Question 1
Correct

A 7-year-old boy presents to the GP clinic with symptoms suggestive of a common cold. He is meeting his developmental milestones as expected, enjoys playing soccer, and has no other health concerns. During auscultation of his chest, you notice a soft, low-pitched murmur that occurs early in systole and is most audible at the lower left sternal border. S1 and a split S2 are both audible, with the latter becoming wider during inspiration. What is the likely diagnosis?
Your Answer: Innocent murmur
Explanation:Innocent Murmurs and Other Heart Conditions in Children
Innocent murmurs are common in children and are considered benign. They are diagnosed through clinical examination and history, and are characterized by a lack of associated symptoms such as feeding difficulties, shortness of breath, and cyanosis. Innocent murmurs are not loud and do not have associated heaves or thrills. They occur in systole and are associated with normal heart sounds. The Valsalva maneuver can reduce their intensity by reducing venous return.
Other heart conditions in children may present with symptoms such as feeding difficulties, shortness of breath, and cyanosis. Abnormal pulses, heaves, and thrills may also be present during examination. Aortic stenosis may be associated with an ejection click and can cause shortness of breath and exertional syncope. Patent ductus arteriosus produces a continuous murmur and may present with cyanosis or breathing difficulties. Pulmonary stenosis is characterized by a widely split second heart sound and may have an ejection systolic click. Ventricular septal defects produce a harsh pan-systolic sound and may be asymptomatic if small.
the differences between innocent murmurs and other heart conditions in children is important for proper diagnosis and treatment. Innocent murmurs are common and benign, while other conditions may require further evaluation and intervention. Clinical examination and history are key in identifying these conditions and determining the appropriate course of action.

A 23-year-old woman with a history of bipolar disorder gives birth to a baby girl at home. She received no prenatal care, but when she found out she was pregnant, she started taking prenatal vitamins that she got from the pharmacist. Her only medication is valproic acid. It is 2 days since the birth, and the mother has brought her baby to the Emergency Department because she has become impossible to arouse. On examination, the baby is estimated to have been born at 35 weeks’ gestation. The baby is afebrile, with stable vital signs. A head ultrasound through the fontanelle shows an intracerebral haemorrhage in the germinal matrix. There are no calcifications. Retinal examination does not show petechial haemorrhages. A full skeletal survey is negative.
What is the most likely pathophysiologic mechanism underlying this baby’s haemorrhage?Your Answer: Vitamin K deficiency
Explanation:Causes of Periventricular Hemorrhage in Neonates
Periventricular hemorrhage is a common condition in neonates that can lead to neurological damage. There are several possible causes of this condition, including vitamin K deficiency, folate deficiency from valproic acid treatment, congenital cytomegalovirus, congenital toxoplasmosis, and congenital herpes simplex virus.
Vitamin K deficiency is a natural occurrence in neonates as they do not have established gut bacteria that produce this vitamin. Vitamin K is essential for the production of clotting factors and anticoagulant proteins. Therefore, neonates born in hospitals are usually injected with vitamin K to prevent periventricular hemorrhage.
Folate deficiency from valproic acid treatment is a common cause of neural tube defects but does not lead to periventricular hemorrhage. Prenatal vitamins usually contain folate, which can prevent this deficiency.
Congenital cytomegalovirus and congenital toxoplasmosis can cause periventricular hemorrhage, but they are also accompanied by other congenital abnormalities, such as intracerebral calcifications.
Congenital herpes simplex virus can cause periventricular hemorrhage and neurological damage, but it also causes a diffuse vesicular rash and other symptoms.

A 6-week-old baby girl is brought to her pediatrician's office by her mother who is worried about her poor feeding over the past 24 hours. The mother has noticed that the baby feels warm but has not observed any signs of cough or cold. The baby is scheduled to receive her vaccinations next week. She has had a wet and dirty diaper today and her urine has a strong odor.
During the examination, the baby has a fever of 38.9ºC and is fussy, but her chest and abdomen appear normal.
What is the most appropriate course of action for this infant?Your Answer: Admit same day to the paediatrics ward for assessment
Explanation:If a child under 3 months old is suspected to have a UTI, it is important to refer them to specialist paediatrics services. In the case of a baby with a persistent fever and no clear source of infection, a urine sample should be collected to check for a UTI. It is important to note that a raised temperature alone is considered a red sign according to NICE guidance for assessing fever in children, and the child should be referred for urgent paediatric assessment. It would be inappropriate to reassure the mother that this is just a virus and can be managed at home, and using paracetamol to manage the fever would not be acceptable in this case. While antibiotics may treat the infection, waiting a week for a review could be dangerous for an unwell child who may deteriorate rapidly. Referring the child for a routine review with paediatrics would also not be appropriate, as urgent attention is required. While a health visitor may be helpful for feeding issues, the short history of poor feeding and fever suggests that the baby is struggling to feed due to illness, and this would not address the current presentation.
Urinary tract infections (UTI) are more common in boys until 3 months of age, after which the incidence is substantially higher in girls. Presentation in childhood depends on age, with infants showing poor feeding, vomiting, and irritability, younger children showing abdominal pain, fever, and dysuria, and older children showing dysuria, frequency, and haematuria. NICE guidelines recommend checking urine samples in children with symptoms or signs suggestive of a UTI, unexplained fever of 38°C or higher, or an alternative site of infection but who remain unwell. Urine collection should be done through clean catch or urine collection pads, and invasive methods should only be used if non-invasive methods are not possible. Management includes referral to a paediatrician for infants less than 3 months old, admission to hospital for children aged more than 3 months old with an upper UTI, and oral antibiotics for 3-10 days for children aged more than 3 months old with a lower UTI. Antibiotic prophylaxis is not given after the first UTI but should be considered with recurrent UTIs.

A 3-year-old boy was brought to his GP by his mother, who had noticed a slight squint in his left eye. During the examination, the GP observed that the red reflex was absent.
What is the most accurate description of this child's condition?Your Answer: There is a significant risk for secondary malignancy in survivors
Explanation:Retinoblastoma: A Rare Eye Cancer with High Survival Rate but Risk of Secondary Malignancy
Retinoblastoma is a rare type of eye cancer that primarily affects children under the age of 5. It is characterized by an abnormal reflection in the pupil, appearing white instead of red, known as leucocoria. Most cases are caused by mutations in the retinoblastoma 1 (RB1) gene, located on chromosome 13, with one-third of cases being inherited in an autosomal dominant pattern. Surgical removal of the tumor, usually through enucleation, is the standard treatment, and the 5-year survival rate is almost 100% if diagnosed and treated promptly.
However, survivors of retinoblastoma are at risk of developing secondary non-ocular tumors, including malignant melanoma, sarcoma, brain tumors, leukemia, and osteosarcoma. Therefore, regular monitoring throughout life is necessary. Most cases are diagnosed before the age of 5, with 90% of cases being diagnosed before the child’s fifth birthday. It is important to note that retinoblastoma is not a recessive condition, and the RB1 gene is located on chromosome 13, not 16.

A 14-year-old boy comes to the GP complaining of left groin pain and a limp that has been gradually developing over the past 5 weeks. He has no medical or family history and his right leg is unaffected. Upon examination, there is a noticeable decrease in internal rotation of the left leg, but no swelling or warmth around the joints. The patient's vital signs are normal, and his height is in the 50th percentile while his weight is in the 95th percentile. What is the most probable diagnosis?
Your Answer: Slipped capital femoral epiphysis
Explanation:Slipped capital femoral epiphysis is more likely to occur in obese boys aged 10-15, as obesity is a risk factor for this condition. It is caused by a weakness in the proximal femoral growth plate, which can also be due to endocrine disorders or rapid growth. Loss of internal rotation of the affected leg is a common finding during examination. Perthes’ disease can also cause groin pain, but it typically affects children aged 4 to 8 years old. Being male and having a lower socioeconomic status are also risk factors for this condition. Septic arthritis is unlikely in this case as the child’s vital signs are normal, and it usually presents with a hot and swollen joint and systemic illness. Developmental dysplasia of the hip is usually detected during routine hip examinations in the first year of life, using Barlow/Ortolani tests and assessing hip abduction.
Slipped Capital Femoral Epiphysis: A Rare Hip Condition in Children
Slipped capital femoral epiphysis, also known as slipped upper femoral epiphysis, is a rare hip condition that primarily affects children between the ages of 10 and 15. It is more commonly seen in obese boys. This condition is characterized by the displacement of the femoral head epiphysis postero-inferiorly, which may present acutely following trauma or with chronic, persistent symptoms.
The most common symptoms of slipped capital femoral epiphysis include hip, groin, medial thigh, or knee pain and loss of internal rotation of the leg in flexion. In some cases, a bilateral slip may occur. Diagnostic imaging, such as AP and lateral (typically frog-leg) views, can confirm the diagnosis.
The management of slipped capital femoral epiphysis typically involves internal fixation, which involves placing a single cannulated screw in the center of the epiphysis. However, if left untreated, this condition can lead to complications such as osteoarthritis, avascular necrosis of the femoral head, chondrolysis, and leg length discrepancy.
In summary, slipped capital femoral epiphysis is a rare hip condition that primarily affects children, especially obese boys. It is characterized by the displacement of the femoral head epiphysis postero-inferiorly and can present with various symptoms. Early diagnosis and management are crucial to prevent complications.

A 16-year-old girl from Manchester is presented to the emergency room by her father with complaints of abdominal discomfort for the past 48 hours. Upon examination, there is a suspicion of appendicitis and a recommendation for hospitalization is made. However, the patient refuses to be admitted as she has a concert to attend tonight. Despite being fully informed of the potential consequences of untreated appendicitis, she insists on leaving. What is the best course of action in this scenario?
Your Answer: His mother may overrule his wishes
Explanation:In England and Wales, a child can provide consent for treatment, but cannot decline it. The demonstration of capacity, as per the Fraser guidelines, is not a significant factor.
Guidelines for Obtaining Consent in Children
The General Medical Council has provided guidelines for obtaining consent in children. According to these guidelines, young people who are 16 years or older can be treated as adults and are presumed to have the capacity to make decisions. However, for children under the age of 16, their ability to understand what is involved determines whether they have the capacity to decide. If a competent child refuses treatment, a person with parental responsibility or the court may authorize investigation or treatment that is in the child’s best interests.
When it comes to providing contraceptives to patients under 16 years of age, the Fraser Guidelines must be followed. These guidelines state that the young person must understand the professional’s advice, cannot be persuaded to inform their parents, is likely to begin or continue having sexual intercourse with or without contraceptive treatment, and will suffer physical or mental health consequences without contraceptive treatment. Additionally, the young person’s best interests require them to receive contraceptive advice or treatment with or without parental consent.
Some doctors use the term Fraser competency when referring to contraception and Gillick competency when referring to general issues of consent in children. However, rumors that Victoria Gillick removed her permission to use her name or applied copyright have been debunked. It is important to note that in Scotland, those with parental responsibility cannot authorize procedures that a competent child has refused.

A 4-year-old girl presents with a 5-day history of fever, increasing irritability, and a rash. Her mother is concerned as she has been giving her paracetamol and ibuprofen but there has been no improvement. During examination, the child's temperature is 39.1°C, respiratory rate is 32 breaths/min, and heart rate is 140 beats/min. Further examination reveals bilateral conjunctivitis without exudate, cervical lymphadenopathy, erythema of the oral mucosa, and a non-vesicular rash that is spreading from her hands and feet. What is the immediate treatment that should be administered?
Your Answer: High dose aspirin and a single dose of intravenous immunoglobulin
Explanation:The appropriate treatment for the child with Kawasaki disease, who meets at least five of the six diagnostic criteria, is a high dose of aspirin and a single dose of intravenous immunoglobulin. The initial dose of aspirin should be 7.5-12.5 mg/kg, given four times a day for two weeks or until the child is afebrile. After that, the dose should be reduced to 2-5 mg/kg once daily for 6-8 weeks. Intravenous immunoglobulin should be administered at a dose of 2 g/kg daily for one dose, and it should be given within 10 days of the onset of symptoms. These recommendations are based on the BNF for Children.
Understanding Kawasaki Disease
Kawasaki disease is a rare type of vasculitis that primarily affects children. It is important to identify this disease early on as it can lead to serious complications, such as coronary artery aneurysms. The disease is characterized by a high-grade fever that lasts for more than five days and is resistant to antipyretics. Other symptoms include conjunctival injection, bright red, cracked lips, strawberry tongue, cervical lymphadenopathy, and red palms and soles that later peel.
Diagnosis of Kawasaki disease is based on clinical presentation as there is no specific diagnostic test available. Management of the disease involves high-dose aspirin, which is one of the few indications for aspirin use in children. Intravenous immunoglobulin is also used as a treatment option. Echocardiogram is the initial screening test for coronary artery aneurysms, rather than angiography.
Complications of Kawasaki disease can be serious, with coronary artery aneurysm being the most common. It is important to recognize the symptoms of Kawasaki disease early on and seek medical attention promptly to prevent potential complications.

A 9-year-old girl presents to a general practice appointment with her mother complaining of right-sided hip pain and occasional limp for the past month. The patient is feeling well, has no fever, and is in the 90th percentile for weight. She was born via spontaneous vertex vaginal delivery at term and had a normal newborn physical examination. On examination, there is limited range of motion in her right hip. A frog-leg hip x-ray is ordered, which reveals sclerosis of the right upper femoral epiphysis and moderate resorption of the femoral head. What is the most accurate diagnosis for this patient?
Your Answer: The condition is 5 times more common in boys
Explanation:Perthes disease is a condition that primarily affects one hip, with only a minority of patients experiencing it in both hips. It is not associated with obesity, unlike slipped capital femoral epiphysis which is more common in overweight children. The management of Perthes disease typically involves conservative measures such as casting or bracing, although surgery may be necessary for older children or those with significant damage to the hip socket. The use of a Pavlik harness is not appropriate for treating Perthes disease, as it is typically used for developmental dysplasia of the hip.
Understanding Perthes’ Disease
Perthes’ disease is a degenerative condition that affects the hip joints of children, typically between the ages of 4-8 years. It is caused by a lack of blood supply to the femoral head, which leads to bone infarction and avascular necrosis. This condition is more common in boys, with around 10% of cases being bilateral. The symptoms of Perthes’ disease include hip pain, stiffness, reduced range of hip movement, and a limp. Early changes can be seen on an x-ray, such as widening of the joint space, while later changes include decreased femoral head size and flattening.
To diagnose Perthes’ disease, a plain x-ray is usually sufficient. However, if symptoms persist and the x-ray is normal, a technetium bone scan or magnetic resonance imaging may be necessary. If left untreated, Perthes’ disease can lead to complications such as osteoarthritis and premature fusion of the growth plates.
The severity of Perthes’ disease is classified using the Catterall staging system, which ranges from stage 1 (clinical and histological features only) to stage 4 (loss of acetabular integrity). Treatment options include keeping the femoral head within the acetabulum using a cast or braces, observation for children under 6 years old, and surgical management for older children with severe deformities. The prognosis for Perthes’ disease is generally good, with most cases resolving with conservative management. Early diagnosis is key to improving outcomes.

A 16-year-old girl comes to her family doctor complaining of bilateral knee pain that has been bothering her for the past four weeks. She mentions that she is a member of her school's track and field team but denies any recent injuries or falls. During the physical examination, the doctor notes tenderness in both of her tibial tuberosities. However, her anterior and posterior cruciate ligament stress tests, as well as the Apley's and McMurray's tests, all yield normal results.
What would be the most appropriate next step?Your Answer: Do no further investigations - advise analgesia, reduce physical exertion and consider physiotherapy
Explanation:Osgood-Schlatter Disease: Diagnosis and Treatment
Osgood-Schlatter disease is a common condition that affects teenagers who are very active in sports. It is caused by traction, which results in numerous microscopic avulsion fractures at the tibial tuberosity. The diagnosis is clinical, and treatment is conservative. X-rays and imaging are usually normal. Physiotherapy may help by strengthening the quadriceps muscles. The pain reduces and resolves, as the bones mature and ossification is completed. It is important to avoid unnecessary investigations and refer to secondary care only if there is suspicion of other conditions.

A 16-year-old boy attends the Emergency Department (ED) with his father. They are both heavily intoxicated with alcohol. The boy’s records show that this is the fourth time in eight months that he has attended the ED with alcohol-related problems. The safeguarding lead has advised you to contact social services.
What is the most suitable course of action in this scenario?Your Answer: Inform the patient and her mother you are referring them to social services
Explanation:Referring a Child at Risk to Social Services: Best Practices
When a child is believed to be at risk, it is crucial to refer them to social services for safeguarding. However, the process of making a referral can be sensitive and requires careful consideration. Here are some best practices to follow:
1. Inform the patient and their parent/guardian about the referral: It is important to inform the patient and their parent/guardian that a referral to social services is being made. However, if there is a risk that informing them could put the child in further danger, the referral should be made without informing them.
2. Seek consent for the referral: Consent should be sought from the patient or their parent/guardian before making a referral. If consent is refused, the referral should still be made, but the patient and/or parent must be fully informed.
3. Refer urgently: If there is a concern that the child is at immediate risk, the referral should be made urgently.
4. Follow up with a written referral: A phone referral should be made initially, but it is important to follow up with a written referral within 48 hours.
By following these best practices, healthcare professionals can ensure that children at risk receive the support and protection they need.

A 16-year-old girl visits your GP practice seeking contraception. After counseling her, you both agree that the implant would be the most suitable option. You believe that she has the ability to make this decision and give her consent for the insertion. However, during previous consultations, you have found her to lack capacity for certain decisions and have involved her parents. According to the GMC, what is necessary to proceed with the implant insertion?
Your Answer: Just the patient's consent.
Explanation:Capacity to make decisions is dependent on both time and the individual’s ability to make decisions. If the patient did not have the capacity to make a decision in the past, but currently has the capacity to do so, their consent is the only one required. It is advisable to involve parents in the decision-making process for pediatric patients, especially in cases involving contraception. However, if the patient is not convinced, the treatment can still proceed as long as they have the capacity to make the decision. If there are doubts, it is good practice to involve another healthcare team member, but if the patient is deemed capable of making the decision, their capacitous consent is sufficient according to the GMC. There is no requirement for a time gap between consultations to allow for decision-making.
Guidelines for Obtaining Consent in Children
The General Medical Council has provided guidelines for obtaining consent in children. According to these guidelines, young people who are 16 years or older can be treated as adults and are presumed to have the capacity to make decisions. However, for children under the age of 16, their ability to understand what is involved determines whether they have the capacity to decide.

A 3-month-old girl is brought to the morning clinic by her father. Since last night she has been taking reduced feeds and has been 'not her usual self'. On examination the baby appears well but has a temperature of 38.5ºC. What is the most suitable course of action?
Your Answer: Admit to hospital
Explanation:The latest NICE guidelines classify any infant under 3 months old with a temperature exceeding 38ºC as a ‘red’ feature, necessitating immediate referral to a paediatrician. While some seasoned GPs may opt not to adhere to this recommendation, it is crucial to stay informed about recent examination guidelines.
The NICE Feverish illness in children guidelines were introduced in 2007 and updated in 2013. These guidelines use a ‘traffic light’ system to assess the risk of children under 5 years old presenting with a fever. It is important to note that these guidelines only apply until a clinical diagnosis of the underlying condition has been made. When assessing a febrile child, their temperature, heart rate, respiratory rate, and capillary refill time should be recorded. Signs of dehydration should also be looked for. Measuring temperature should be done with an electronic thermometer in the axilla if the child is under 4 weeks old or with an electronic/chemical dot thermometer in the axilla or an infrared tympanic thermometer.
The risk stratification table includes green for low risk, amber for intermediate risk, and red for high risk. The table includes categories such as color, activity, respiratory, circulation and hydration, and other symptoms. If a child is categorized as green, they can be managed at home with appropriate care advice. If they are categorized as amber, parents should be provided with a safety net or referred to a pediatric specialist for further assessment. If a child is categorized as red, they should be urgently referred to a pediatric specialist. It is important to note that oral antibiotics should not be prescribed to children with fever without an apparent source, and a chest x-ray does not need to be routinely performed if a pneumonia is suspected but the child is not going to be referred to the hospital.

Question 13

A 9-month-old baby is presented to the emergency department due to vomiting and diarrhoea that has been going on for 2 days. The vomit and stools are unremarkable, but the father reports that the baby has been lethargic and unsettled for the past 3 days. Additionally, the baby has had 6 episodes of uncontrollable crying where he draws his legs up to his chest for a few minutes at a time. The baby has no fever. During the examination, the baby appears pale and lethargic, and a small mass is palpated in the right upper quadrant. To investigate further, a plain abdominal x-ray is performed, which shows no signs of obstruction, and an ultrasound scan reveals a target sign. What is the most probable diagnosis?
Your Answer: Intussusception
Explanation:This question pertains to gastrointestinal disorders in children, specifically focusing on the symptoms of vomiting and diarrhea. While there can be various reasons for these symptoms, the child in this scenario displays indications of Intussusception. One of the classic signs is the child crying intermittently and pulling their legs towards their chest. Additionally, the presence of a small mass in the right upper quadrant and a target sign on ultrasound further support this diagnosis, along with the vomiting, diarrhea, and pain.
The vomit and stool do not show any significant abnormalities, and the absence of a fever suggests that it is not an infectious episode. Pyloric stenosis is unlikely to present in this manner. However, before an abdominal ultrasound x-ray is conducted, it is not possible to rule out a small bowel obstruction. Nevertheless, there are no indications of obstruction on the x-ray.
Understanding Intussusception
Intussusception is a medical condition that occurs when one part of the bowel folds into the lumen of the adjacent bowel, usually around the ileo-caecal region. This condition is most common in infants between 6-18 months old, with boys being affected twice as often as girls. The symptoms of intussusception include severe, crampy abdominal pain that comes and goes, inconsolable crying, vomiting, and blood stained stool, which is a late sign. During a paroxysm, the infant will typically draw their knees up and turn pale, and a sausage-shaped mass may be felt in the right upper quadrant.
To diagnose intussusception, ultrasound is now the preferred method of investigation, as it can show a target-like mass. Treatment for intussusception involves reducing the bowel by air insufflation under radiological control, which is now widely used as a first-line treatment instead of the traditional barium enema. If this method fails, or the child shows signs of peritonitis, surgery is performed.
In summary, intussusception is a medical condition that affects infants and involves the folding of one part of the bowel into the lumen of the adjacent bowel. It is characterized by severe abdominal pain, vomiting, and blood stained stool, among other symptoms. Ultrasound is the preferred method of diagnosis, and treatment involves reducing the bowel by air insufflation or surgery if necessary.

A 2-year-old girl presents to the emergency department with a 1-day history of rectal bleeding. Her parents report seeing fresh blood in her nappies mixed with her stool. Upon examination, she appears alert, active, afebrile, and hemodynamically stable. She has non-specific abdominal tenderness without guarding, and there is no active bleeding. An abdominal ultrasound is performed, which shows no abnormalities. Meckel's diverticulum is suspected. What is the most appropriate next step in investigating this patient?
Your Answer: Technetium scan
Explanation:When investigating stable children with suspected Meckel’s diverticulum, a technetium scan is the preferred method.
Meckel’s diverticulum is a small pouch in the small intestine that is present from birth. It is a leftover part of the omphalomesenteric duct, which is also known as the vitellointestinal duct. The diverticulum can contain tissue from the ileum, stomach, or pancreas. This condition is relatively rare, occurring in only 2% of the population. Meckel’s diverticulum is typically located about 2 feet from the ileocaecal valve and is around 2 inches long.
In most cases, Meckel’s diverticulum does not cause any symptoms and is only discovered incidentally during medical tests. However, it can cause abdominal pain that is similar to appendicitis, rectal bleeding, and intestinal obstruction. In fact, it is the most common cause of painless massive gastrointestinal bleeding in children between the ages of 1 and 2 years.
To diagnose Meckel’s diverticulum, doctors may perform a Meckel’s scan using a radioactive substance that has an affinity for gastric mucosa. In more severe cases, mesenteric arteriography may be necessary. Treatment typically involves surgical removal of the diverticulum if it has a narrow neck or is causing symptoms. The options for surgery include wedge excision or formal small bowel resection and anastomosis.
Meckel’s diverticulum is caused by a failure of the attachment between the vitellointestinal duct and the yolk sac to disappear during fetal development. The diverticulum is typically lined with ileal mucosa, but it can also contain ectopic gastric, pancreatic, or jejunal mucosa. This can increase the risk of peptic ulceration and other complications. Meckel’s diverticulum is often associated with other conditions such as enterocystomas, umbilical sinuses, and omphalocele fistulas.

You are requested to attend an elective Caesarean section for macrosomia and maternal diabetes. When should you evaluate the APGAR scores during the procedure?
Your Answer: 1, 5 minutes
Explanation:NICE guidelines suggest that APGAR scores be regularly evaluated at both 1 and 5 minutes after birth. It is expected that the scores will show improvement over time, but if they remain low, they should be rechecked. The APGAR acronym stands for the assessment of Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiratory effort.
The Apgar score is a tool used to evaluate the health of a newborn baby. It is recommended by NICE to be assessed at 1 and 5 minutes after birth, and again at 10 minutes if the initial score is low. The score is based on five factors: pulse, respiratory effort, color, muscle tone, and reflex irritability. A score of 0-3 is considered very low, 4-6 is moderate low, and 7-10 indicates that the baby is in good health. The score helps healthcare professionals quickly identify any potential issues and provide appropriate care.

A 10 week old male infant is presented to the GP by his mother with concerns about an undescended testis on the right side since birth. The mother was advised to seek medical attention if the issue persisted after 6 to 8 weeks of age. Upon examination, the GP confirms the presence of a unilateral undescended testis on the right side, with a normal appearing penis. What would be the next step in management?
Your Answer: Review at 3 months of age
Explanation:If the testicle remains undescended after 3 months, it is recommended to refer the child to a paediatric surgeon for review before they reach 6 months of age, as per the NICE guidelines for undescended testes.
Undescended Testis: Causes, Complications, and Management
Undescended testis is a condition that affects around 2-3% of male infants born at term, but it is more common in preterm babies. Bilateral undescended testes occur in about 25% of cases. This condition can lead to complications such as infertility, torsion, testicular cancer, and psychological issues.
To manage unilateral undescended testis, NICE CKS recommends considering referral from around 3 months of age, with the baby ideally seeing a urological surgeon before 6 months of age. Orchidopexy, a surgical procedure, is typically performed at around 1 year of age, although surgical practices may vary.
For bilateral undescended testes, it is crucial to have the child reviewed by a senior paediatrician within 24 hours as they may require urgent endocrine or genetic investigation. Proper management of undescended testis is essential to prevent complications and ensure the child’s overall health and well-being.

Correct Answer: Auditory Brainstem Response test as a newborn/infant
Explanation:When a newborn baby’s hearing test at birth shows an abnormal result, they are recommended to undergo an auditory brainstem response test as a newborn or infant. Prior to being discharged from the hospital, all newborns should have an acoustic emission test, which involves placing a soft earpiece in the baby’s ear and playing quiet clicking sounds to detect inner ear responses. If this test yields abnormal results, the auditory brainstem response test is conducted using three sensors placed on the baby’s head and neck, along with soft headphones to play sounds and analyze the brain and hearing nerve responses. At 6-9 months of age, a distraction test is performed, and most areas in the UK conduct pure tone audiometry at school entry.
Hearing Tests for Children
Hearing tests are important for children to ensure that they are developing normally. There are several tests that may be performed on children of different ages. For newborns, an otoacoustic emission test is typically done as part of the Newborn Hearing Screening Programme. This test involves playing a computer-generated click through a small earpiece and checking for the presence of a soft echo, which indicates a healthy cochlea. If the results of this test are abnormal, an Auditory Brainstem Response test may be done.
For infants between 6-9 months, a Distraction test may be performed by a health visitor with the help of two trained staff members. For children between 18 months to 2.5 years, a Recognition of familiar objects test may be used, which involves using familiar objects like a teddy or cup and asking the child simple questions like where is the teddy? For children over 2.5 years, Performance testing and Speech discrimination tests may be used, such as the Kendall Toy test or McCormick Toy Test. Pure tone audiometry is typically done at school entry in most areas of the UK for children over 3 years old.
In addition to these tests, there is also a questionnaire for parents in the Personal Child Health Records called Can your baby hear you? It is important for parents to be aware of these tests and to have their child’s hearing checked regularly to ensure proper development.

A 41-year-old female with a history of Leber's optic atrophy visits her doctor. She and her husband are planning to have children and she wants to know the likelihood of passing on her condition. She vaguely remembers her geneticist mentioning something about mitochondria but can't recall the specifics of the inheritance pattern. Assuming her husband does not carry the same gene defect, what is the chance that their child will inherit the condition?
Your Answer: 0%
Explanation:Mitochondrial disorders encompass a range of conditions, such as leigh syndrome, mitochondrial diabetes, MELAS syndrome, and MERFF syndrome.
Mitochondrial Diseases: Inheritance and Histology
Mitochondrial diseases are caused by mutations in the small amount of double-stranded DNA present in the mitochondria. This DNA encodes protein components of the respiratory chain and some special types of RNA. Mitochondrial inheritance has unique characteristics, including inheritance only via the maternal line and none of the children of an affected male inheriting the disease. However, all of the children of an affected female will inherit the disease. These diseases generally encode rare neurological diseases and have a poor genotype-phenotype correlation due to heteroplasmy, where different mitochondrial populations exist within a tissue or cell.
Histologically, muscle biopsy shows red, ragged fibers due to an increased number of mitochondria. Some examples of mitochondrial diseases include Leber’s optic atrophy, MELAS syndrome (mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes), MERRF syndrome (myoclonus epilepsy with ragged-red fibers), Kearns-Sayre syndrome (onset in patients < 20 years old, external ophthalmoplegia, retinitis pigmentosa, and ptosis may be seen), and sensorineural hearing loss.

A mother brings her 9-month-old son to the general practitioner. She is concerned, as he has had an unusually high-pitched cry and has been drawing his legs up and vomiting. His last nappy revealed some bloody, slimy stools. She has recently started to wean him.
Which is the most likely diagnosis?Your Answer: Intussusception
Explanation:Pediatric Gastrointestinal Conditions: Symptoms and Differentiation
Intussusception: A pediatric emergency condition where a bowel segment invaginates into a neighboring part of the bowel, causing obstruction. Symptoms include vomiting, abdominal pain, passing blood and mucous per rectum, lethargy, and a palpable abdominal mass. Diagnosis is via ultrasonography, and treatment can be non-operative or operative depending on the severity.
Food Intolerance: Occurs following ingestion of an allergen and presents with diarrhea, vomiting, wheezing, pruritus, and rash. Typically seen in children at the age of weaning.
Colic: Excessive, high-pitched crying in infants, typically in the evenings. Can relate to a variety of causes, including gastro-oesophageal reflux, overfeeding, incomplete burping following feeds, and food allergy.
Pyloric Stenosis: Caused by hypertrophy of the pyloric muscle leading to gastric outlet obstruction. Presents in the first weeks of life with projectile non-bilious vomiting, a palpable mass in the abdomen, and visible peristalsis.
Cystic Fibrosis: An inherited condition associated with mutations in the cystic fibrosis transmembrane conductance regulator, affecting the transmembrane transport of chloride ions and leading to thick secretions in the lungs and bowel. Symptoms include meconium ileus, constipation, abdominal distension, bilious vomiting, diarrhea, steatorrhea, failure to thrive, and rectal prolapse. Identified by heel-prick screening at birth or around the age of 6-8 months.

You have just assisted with the normal vaginal delivery of a baby boy, during the delivery there was a large amount of meconium. On observation of the baby just after the birth, what signs would indicate the need for the neonatal team to evaluate the baby?
Your Answer: Respiratory rate 75/minute
Explanation:The Apgar score is a tool used to evaluate the health of a newborn baby. It is recommended by NICE to be assessed at 1 and 5 minutes after birth, and again at 10 minutes if the initial score is low. The score is based on five factors: pulse, respiratory effort, color, muscle tone, and reflex irritability. A score of 0-3 is considered very low, 4-6 is moderate low, and 7-10 indicates that the baby is in good health. The score helps healthcare professionals quickly identify any potential issues and provide appropriate care.

You are conducting an 8-month well-baby visit for a boy and his mother. The physical examination is normal, and you proceed to discuss the child's immunizations. The mother expresses concern about recent measles outbreaks and asks when her son should receive the first dose of the MMR vaccine.
When is the MMR vaccine typically administered as part of routine immunizations?Your Answer: At 12-13 months of age
Explanation:The MMR vaccine is administered as a standard practice when a child reaches 12-13 months of age, and then again during the preschool booster at 3-4 years old.
The UK immunisation schedule recommends certain vaccines at different ages. At birth, the BCG vaccine is given if the baby is at risk of tuberculosis. At 2, 3, and 4 months, the ‘6-1 vaccine’ (diphtheria, tetanus, whooping cough, polio, Hib and hepatitis B) and oral rotavirus vaccine are given, along with Men B and PCV at certain intervals. At 12-13 months, the Hib/Men C, MMR, and PCV vaccines are given, along with Men B. At 3-4 years, the ‘4-in-1 preschool booster’ (diphtheria, tetanus, whooping cough and polio) and MMR vaccines are given. At 12-13 years, the HPV vaccination is given, and at 13-18 years, the ‘3-in-1 teenage booster’ (tetanus, diphtheria and polio) and Men ACWY vaccines are given. Additionally, the flu vaccine is recommended annually for children aged 2-8 years.
It is important to note that the meningitis ACWY vaccine has replaced meningitis C for 13-18 year-olds due to an increased incidence of meningitis W disease in recent years. The ACWY vaccine will also be offered to new students (up to the age of 25 years) at university. GP practices will automatically send letters inviting 17-and 18-year-olds in school year 13 to have the Men ACWY vaccine. Students going to university or college for the first time as freshers, including overseas and mature students up to the age of 25, should contact their GP to have the Men ACWY vaccine, ideally before the start of the academic year.
It is worth noting that the Men C vaccine used to be given at 3 months but has now been discontinued. This is because the success of the Men C vaccination programme means there are almost no cases of Men C disease in babies or young children in the UK any longer. All children will continue to be offered the Hib/Men C vaccine at one year of age, and the Men ACWY vaccine at 14 years of age to provide protection across all age groups.

A female infant is presenting with dyspnea and cyanosis. The mother attempted to feed her but noticed milk coming out of her nose and difficulty breathing during feeding. Upon examination, the infant was found to be tachypneic and tachycardic with intercostal recession. A bulge was observed on the praecordium and an early systolic murmur was heard along the left sternal edge. The chest x-ray revealed cardiomegaly, a loss of the normal thymus shadow, and a right aortic notch. Blood tests were normal except for low corrected serum calcium. What is the most likely diagnosis?
Your Answer: DiGeorge syndrome
Explanation:DiGeorge Syndrome
DiGeorge syndrome is a genetic disorder caused by a deletion of chromosomal region 22q11.2. It affects around 1 in 3000 live births and is characterized by a spectrum of disorders. The poor migration of neural crest cells to the third and fourth pharyngeal pouches is thought to be the cause of the midline abnormalities found in DiGeorge syndrome. These abnormalities include cardiac defects, abnormal facies, thymic hypoplasia, and hypocalcemia.
Characteristic facies develop as the child grows and include high broad noses, low set ears, small teeth, and narrow eyes. Other systems may also be affected, and cognitive and psychiatric problems are common but variable. Around 80% of patients have an associated cardiac defect, often of a conotruncal variety. Tetralogy of Fallot is also found, as are other defects such as ventricular septal defects and atrial septal defects.
The diagnosis of DiGeorge syndrome can be difficult, but clinical features consistent with the diagnosis include abnormalities of heart sounds and features of cardiac failure or cyanosis. The chest x-ray helps with the diagnosis, and an echocardiogram and possibly high resolution contrast CT imaging would be helpful in these cases. The above example has a persistent truncus arteriosus, which is a failure to separate the aorta and the main pulmonary artery. This can lead to dyspnea, cyanosis, and cardiac failure.
In summary, DiGeorge syndrome is a complex disorder that affects multiple systems in the body. Early diagnosis and management are crucial to prevent complications and improve outcomes for affected individuals.

A premature infant is born at 30 weeks gestation through a spontaneous vaginal delivery. The amniotic fluid did not show any signs of meconium staining. However, the baby develops sternal recession, tachypnea, grunting, and cyanosis shortly after birth. What is the probable diagnosis?
Your Answer: Neonatal respiratory distress syndrome (NRDS)
Explanation:When answering questions about respiratory issues in newborns, it is important to consider the risk factors involved. Prematurity is the primary risk factor for neonatal respiratory distress syndrome (NRDS), while caesarean section increases the risk of tachypnea of the newborn (TTN). Meconium staining is a significant risk factor for aspiration pneumonia.
Symptoms of NRDS typically include respiratory distress that worsens over the first few days after birth. TTN, on the other hand, is characterized by rapid breathing shortly after birth, which often resolves within the first day of life. A chest X-ray can be helpful in diagnosing these conditions. NRDS is typically indicated by a diffuse ground glass appearance in the lungs, low lung volumes, and a bell-shaped thorax. TTN, on the other hand, may show a pattern similar to heart failure on the X-ray, with interstitial edema and pleural effusions, but with a normal heart size and rapid resolution of the pattern within a few days.
Surfactant Deficient Lung Disease in Premature Infants
Surfactant deficient lung disease (SDLD), previously known as hyaline membrane disease, is a condition that affects premature infants. It occurs due to the underproduction of surfactant and the immaturity of the lungs’ structure. The risk of SDLD decreases with gestation, with 50% of infants born at 26-28 weeks and 25% of infants born at 30-31 weeks being affected. Other risk factors include male sex, diabetic mothers, Caesarean section, and being the second born of premature twins.
The clinical features of SDLD are similar to those of respiratory distress in newborns, including tachypnea, intercostal recession, expiratory grunting, and cyanosis. Chest x-rays typically show a ground-glass appearance with an indistinct heart border.
Prevention during pregnancy involves administering maternal corticosteroids to induce fetal lung maturation. Management of SDLD includes oxygen therapy, assisted ventilation, and exogenous surfactant given via an endotracheal tube. With proper management, the prognosis for infants with SDLD is generally good.

You are discussing conception with two parents who both have achondroplasia. They ask you what the chances are that a child of theirs would be of average height. What is the appropriate answer?
Your Answer: 25%
Explanation:Understanding Achondroplasia
Achondroplasia is a genetic disorder that is inherited in an autosomal dominant manner. It is caused by a mutation in the fibroblast growth factor receptor 3 (FGFR-3) gene, which leads to abnormal cartilage development. This results in short stature, with affected individuals having short limbs (rhizomelia) and shortened fingers (brachydactyly). They also have a large head with frontal bossing and a narrow foramen magnum, midface hypoplasia with a flattened nasal bridge, ‘trident’ hands, and lumbar lordosis.
In most cases, achondroplasia occurs as a sporadic mutation, with advancing parental age at the time of conception being a risk factor. There is no specific therapy for achondroplasia, but some individuals may benefit from limb lengthening procedures. These procedures involve the application of Ilizarov frames and targeted bone fractures, with a clearly defined need and endpoint being essential for success.
Overall, understanding achondroplasia is important for individuals and families affected by this condition. While there is no cure, there are treatment options available that can improve quality of life for those living with achondroplasia.

At what age is precocious puberty in males defined as the development of secondary sexual characteristics occurring before?
Your Answer: 9 years of age
Explanation:Understanding Precocious Puberty
Precocious puberty is a condition where secondary sexual characteristics develop earlier than expected, before the age of 8 in females and 9 in males. It is more common in females and can be classified into two types: gonadotrophin dependent and gonadotrophin independent. The former is caused by premature activation of the hypothalamic-pituitary-gonadal axis, resulting in raised levels of FSH and LH. The latter is caused by excess sex hormones, with low levels of FSH and LH. In males, precocious puberty is uncommon and usually has an organic cause, such as gonadotrophin release from an intracranial lesion, gonadal tumour, or adrenal cause. In females, it is usually idiopathic or familial and follows the normal sequence of puberty. Organic causes are rare and associated with rapid onset, neurological symptoms and signs, and dissonance, such as in McCune Albright syndrome. Understanding precocious puberty is important for early detection and management of the condition.

A 10-year-old boy visits his family doctor complaining of a limp that has been bothering him for the past 48 hours. He mentions having a runny nose and cough for a few days, but he feels better today. He reports pain in his left hip.
During the examination, the boy seems to be in good spirits and can bear weight with an antalgic gait.
His blood pressure is 110/70 mmHg, and his heart rate is 90 beats per minute. His respiratory rate is 16 breaths per minute, and his temperature is 38.5ºC.
What is the most appropriate course of action based on this information?Your Answer: Refer urgently for same-day assessment
Explanation:The option to reassure and provide safety netting advice is not appropriate for a child with an acutely irritable hip and fever >38.5ºC, as septic arthritis is a possible diagnosis that requires urgent assessment, including synovial aspiration. Although transient tenosynovitis is the most likely diagnosis, the presence of fever warrants further investigation to rule out septic arthritis. The recommendation of a Pavlik harness and orthopaedic review is not applicable unless developmental dysplasia of the hip is confirmed. Rest and over-the-counter analgesia are not sufficient management for this patient, as urgent referral for same-day assessment is necessary to exclude septic arthritis.
Transient synovitis, also known as irritable hip, is a common cause of hip pain in children aged 3-8 years. It typically occurs following a recent viral infection and presents with symptoms such as groin or hip pain, limping or refusal to weight bear, and occasionally a low-grade fever. However, a high fever may indicate other serious conditions such as septic arthritis, which requires urgent specialist assessment. To exclude such diagnoses, NICE Clinical Knowledge Summaries recommend monitoring children in primary care with a presumptive diagnosis of transient synovitis, provided they are aged 3-9 years, well, afebrile, mobile but limping, and have had symptoms for less than 72 hours. Treatment for transient synovitis involves rest and analgesia, as the condition is self-limiting.

A 4-month-old is brought to the emergency department with a suspected UTI and responds well to antibiotics within 48 hours. An ultrasound may be necessary to determine if this is a typical or atypical UTI. What is the most common indicator of an atypical UTI?
Your Answer: Poor urine flow
Explanation:If an infant under 6 months shows signs of an atypical UTI, it is important to schedule an ultrasound scan during their acute admission. Atypical UTI may be indicated by symptoms such as poor urine flow, an abdominal or bladder mass, raised creatinine, septicaemia, failure to respond to appropriate antibiotics within 48 hours, or infection with non-E. coli organisms. However, raised white blood cells alone do not necessarily indicate septicaemia, and abdominal pain is a common symptom of UTI but does not necessarily indicate an atypical UTI.
Urinary tract infections (UTI) are more common in boys until 3 months of age, after which the incidence is substantially higher in girls. Presentation in childhood depends on age, with infants showing poor feeding, vomiting, and irritability, younger children showing abdominal pain, fever, and dysuria, and older children showing dysuria, frequency, and haematuria. NICE guidelines recommend checking urine samples in children with symptoms or signs suggestive of a UTI, unexplained fever of 38°C or higher, or an alternative site of infection but who remain unwell. Urine collection should be done through clean catch or urine collection pads, and invasive methods should only be used if non-invasive methods are not possible. Management includes referral to a paediatrician for infants less than 3 months old, admission to hospital for children aged more than 3 months old with an upper UTI, and oral antibiotics for 3-10 days for children aged more than 3 months old with a lower UTI. Antibiotic prophylaxis is not given after the first UTI but should be considered with recurrent UTIs.

A 7-year-old girl is brought to the pediatrician's office by her father. She has been experiencing nighttime itching around her bottom and has mentioned to her father that she has seen small white strands moving in her stool. She is not constipated and is generally healthy. No one else in the household has reported similar symptoms. The girl lives with her father and her two-year-old brother.
What should be the next course of action?Your Answer: Mebendazole and hygiene measures for the patient and his parents, as his sister is too young
Explanation:It is recommended to treat asymptomatic household contacts of patients with threadworms, even if they show no symptoms. In the case of this boy with threadworms, the appropriate course of action would be to administer Mebendazole and advise on hygiene measures for both the patient and his parents. It is not necessary to send a sample to the laboratory for confirmation as empirical treatment is recommended. Advising on hygiene and fluid intake alone would not be sufficient to treat the infection. It is important to note that Mebendazole should not be given to children under six months old, so treating the patient’s three-month-old sister is not appropriate. Permethrin is not a suitable treatment for threadworms as it is used to treat scabies.
Threadworm Infestation in Children
Threadworm infestation, caused by Enterobius vermicularis or pinworms, is a common occurrence among children in the UK. The infestation happens when eggs present in the environment are ingested. In most cases, threadworm infestation is asymptomatic, but some possible symptoms include perianal itching, especially at night, and vulval symptoms in girls. Diagnosis can be made by applying Sellotape to the perianal area and sending it to the laboratory for microscopy to see the eggs. However, most patients are treated empirically, and this approach is supported in the CKS guidelines.
The CKS recommends a combination of anthelmintic with hygiene measures for all members of the household. Mebendazole is the first-line treatment for children over six months old, and a single dose is given unless the infestation persists. It is essential to treat all members of the household to prevent re-infection. Proper hygiene measures, such as washing hands regularly, keeping fingernails short, and washing clothes and bedding at high temperatures, can also help prevent the spread of threadworm infestation.

A 6-day-old baby who is 39+6 weeks’ gestation on the Neonatal Unit develops jaundice with a conjugated fraction of 42% (reference < 20%). The baby has feeding difficulty and so is being fed through a nasogastric tube. Investigations are being completed into a diagnosis of conjugated hyperbilirubinaemia. The baby is currently under single phototherapy for his jaundice.
What is the most suitable course of treatment?Your Answer: Ursodeoxycholic acid
Explanation:Treatment Options for Conjugated Hyperbilirubinaemia in Neonates
Conjugated hyperbilirubinaemia in neonates can be caused by various factors, including biliary atresia and choledochal cysts. Ursodeoxycholic acid is a commonly used treatment option for reducing serum bilirubin levels by decreasing bile flow, intestinal absorption of bile acids, and bilirubin concentration. On the other hand, caffeine is given to preterm neonates to improve their cardiac drive and apnoea but is not used for hyperbilirubinaemia. Phototherapy is the first-line treatment for jaundice, but increasing light concentration does not target the conjugated fraction. Milk fortifier may be useful for poor growth or meeting gestational criteria, but it has no place in the treatment of hyperbilirubinaemia. Omeprazole is given for reflux but does not aid in the management of hyperbilirubinaemia.

A 12-year-old boy comes to see his GP complaining of hip and knee pain on one side. He reports that the pain started 2 weeks ago after he was tackled while playing football. His limp has become more pronounced recently. During the examination, the doctor notes a reduced ability to internally rotate the leg when flexed. The boy has no fever and his vital signs are stable. What is the probable diagnosis?
Your Answer: Slipped capital femoral epiphysis
Explanation:Slipped capital femoral epiphysis is often associated with a loss of internal rotation of the leg in flexion. Acute transient synovitis is an incorrect answer as it typically resolves within 1-2 weeks and is often preceded by an upper respiratory infection. Developmental dysplasia of the hip is typically diagnosed in younger children and can be detected using the Barlow and Ortolani tests. While Perthes’ disease is a possibility, the loss of internal rotation of the leg in flexion makes slipped capital femoral epiphysis a more likely diagnosis. Septic arthritis would present with a fever and may result in difficulty bearing weight.
Slipped Capital Femoral Epiphysis: A Rare Hip Condition in Children
Slipped capital femoral epiphysis, also known as slipped upper femoral epiphysis, is a rare hip condition that primarily affects children between the ages of 10 and 15. It is more commonly seen in obese boys. This condition is characterized by the displacement of the femoral head epiphysis postero-inferiorly, which may present acutely following trauma or with chronic, persistent symptoms.
The most common symptoms of slipped capital femoral epiphysis include hip, groin, medial thigh, or knee pain and loss of internal rotation of the leg in flexion. In some cases, a bilateral slip may occur. Diagnostic imaging, such as AP and lateral (typically frog-leg) views, can confirm the diagnosis.
The management of slipped capital femoral epiphysis typically involves internal fixation, which involves placing a single cannulated screw in the center of the epiphysis. However, if left untreated, this condition can lead to complications such as osteoarthritis, avascular necrosis of the femoral head, chondrolysis, and leg length discrepancy.
In summary, slipped capital femoral epiphysis is a rare hip condition that primarily affects children, especially obese boys. It is characterized by the displacement of the femoral head epiphysis postero-inferiorly and can present with various symptoms. Early diagnosis and management are crucial to prevent complications.

A 7-year-old girl is diagnosed with Attention Deficit Hyperactivity Disorder and prescribed methylphenidate. What should be monitored during her treatment?
Your Answer: Growth
Explanation:In March 2018, NICE released new guidelines for identifying and managing Attention Deficit Hyperactivity Disorder (ADHD). This condition can have a significant impact on a child’s life and can continue into adulthood, making accurate diagnosis and treatment crucial. According to DSM-V, ADHD is characterized by persistent features of inattention and/or hyperactivity/impulsivity, with an element of developmental delay. Children up to the age of 16 must exhibit six of these features, while those aged 17 or over must exhibit five. ADHD has a UK prevalence of 2.4%, with a higher incidence in boys than girls, and there may be a genetic component.
NICE recommends a holistic approach to treating ADHD that is not solely reliant on medication. After presentation, a ten-week observation period should be implemented to determine if symptoms change or resolve. If symptoms persist, referral to secondary care is necessary, typically to a paediatrician with a special interest in behavioural disorders or to the local Child and Adolescent Mental Health Service (CAMHS). A tailored plan of action should be developed, taking into account the patient’s needs and wants, as well as how their condition affects their lives.
Drug therapy should be considered a last resort and is only available to those aged 5 years or older. Parents of children with mild/moderate symptoms can benefit from attending education and training programmes. For those who do not respond or have severe symptoms, pharmacotherapy may be considered. Methylphenidate is the first-line treatment for children and should be given on a six-week trial basis. It is a CNS stimulant that primarily acts as a dopamine/norepinephrine reuptake inhibitor. Side effects include abdominal pain, nausea, and dyspepsia. Weight and height should be monitored every six months in children. If there is an inadequate response, lisdexamfetamine should be considered, followed by dexamfetamine if necessary. In adults, methylphenidate or lisdexamfetamine are the first-line options, with switching between drugs if no benefit is seen after a trial of the other. All of these drugs are potentially cardiotoxic, so a baseline ECG should be performed before starting treatment, and referral to a cardiologist should be made if there is any significant past medical history or family history, or any doubt or ambiguity.
As with most psychiatric conditions, a thorough history and clinical examination are essential, particularly given the overlap of ADHD with many other psychiatric and

Which of the features below, following a head injury, is not an indication for an immediate CT head scan in adolescents?
Your Answer: A single, discrete episode of vomiting
Explanation:Although immediate CT is not necessary, patients should be admitted and closely monitored with a low threshold.
Criteria for Immediate CT Scan of Head in Paediatric Head Injury Cases
Head injuries in children can be serious and require immediate medical attention. In some cases, a CT scan of the head may be necessary to assess the extent of the injury. The following criteria are used to determine when an immediate CT scan is required:
– Loss of consciousness lasting more than 5 minutes (witnessed)
– Amnesia (antegrade or retrograde) lasting more than 5 minutes
– Abnormal drowsiness
– Three or more discrete episodes of vomiting
– Clinical suspicion of non-accidental injury
– Post-traumatic seizure but no history of epilepsy
– GCS less than 14, or for a baby under 1 year GCS (paediatric) less than 15, on assessment in the emergency department
– Suspicion of open or depressed skull injury or tense fontanelle
– Any sign of basal skull fracture (haemotympanum, panda’ eyes, cerebrospinal fluid leakage from the ear or nose, Battle’s sign)
– Focal neurological deficit
– If under 1 year, presence of bruise, swelling or laceration of more than 5 cm on the head
– Dangerous mechanism of injury (high-speed road traffic accident either as pedestrian, cyclist or vehicle occupant, fall from a height of greater than 3 m, high-speed injury from a projectile or an object)It is important for healthcare professionals to be aware of these criteria and to promptly order a CT scan when necessary to ensure the best possible outcome for the child.

A 4-week-old baby boy is brought in by his concerned parents. Since two weeks of age, he has had a slowly expanding lump to the left side of his head. He is otherwise healthy, gaining weight, and breastfeeding well. He wakes to demand food and is starting to show signs of social smiling. He was delivered by unassisted normal vaginal delivery at 38 weeks’ gestation after an uncomplicated pregnancy. Birthweight was 3.2 kg. Other than a slightly prolonged second stage of labor, there is no significant perinatal history. He has no siblings and there is no family history of note.
During the examination, an alert and active baby is observed. Vital signs are normal. There is a smooth lump measuring 2 × 3 cm arising in the left parieto-occipital region. The lump is compressible and non-pulsatile and does not cross the suture lines. A head to toe examination of the baby reveals no other lumps, skin lesions, rashes, or marks. The anterior fontanelle is normal. The baby has good tone and a normal Moro reflex. There is no jaundice or pallor.
What is the most likely diagnosis?Your Answer: Cephalohaematoma
Explanation:Common Neonatal Head Injuries: Causes, Symptoms, and Differences
Cephalohaematoma, Caput succedaneum, Cephalocele, and Subgaleal haemorrhage are common neonatal head injuries that can occur during birth. Understanding the causes, symptoms, and differences between these injuries is important for proper diagnosis and treatment.
Cephalohaematoma is a subperiosteal haemorrhage that occurs in 1-2% of live births, usually associated with a prolonged second stage of labour. It presents as a well-circumscribed, fluctuant mass over the parietal bone, and does not cross suture lines. Complications such as anaemia and jaundice can result from a cephalohaematoma, depending on its size.
Caput succedaneum is a form of birth trauma caused by pressure exerted on the presenting part by the cervix during the first stage of labour. It presents as diffuse swelling of the scalp and is associated with moulding. It can cross the midline and extends over suture lines. It resolves over the course of the first few days of life.
Cephalocele is a rare congenital condition where brain herniation occurs through a defect in the cranium. It is usually detected antenatally and most commonly presents in the midline.
Subgaleal haemorrhage is most commonly associated with instrumental delivery, caused by rupture of the emissary veins connecting the dural sinuses with the scalp veins. It presents as a fluctuant mass over the occiput, with superficial skin bruising 12-72 hours post-delivery. It may cross suture lines and pass over fontanelles, distinguishing it from a cephalohaematoma.
It is important to note that non-accidental injury should always be considered in cases of unexplained head injuries. However, in the absence of any concerning features, a cephalohaematoma or other neonatal head injury is likely due to birth trauma and can be managed accordingly.

A 14 kg 2-year-old girl with a history of vomiting and diarrhea for 4 days is brought to the pediatric emergency department due to increasing fussiness and fatigue. The child has not eaten anything for the past 24 hours and has only been able to tolerate a small amount of fluids. The mother also noticed that the child has been urinating less frequently.
Upon examination, the child appears lethargic and unresponsive. The heart rate is 155 beats per minute (normal range: 90-140/min), respiratory rate is 30 breaths per minute (normal range: 20-30/min), and systolic blood pressure is 88 mmHg (normal range: 80-100 mmHg). The child's temperature is within normal limits.
There are no skin rashes present. The capillary refill time is 3 seconds, and the child's extremities are cold and pale. Skin turgor is decreased, and the mucous membranes are dry. What can you conclude about the hydration status of the girl and how would you manage the patient based on your conclusion?Your Answer: There is early (compensated) shock. Urgent fluid resuscitation is needed
Explanation:Managing Diarrhoea and Vomiting in Children
Diarrhoea and vomiting are common in young children, with rotavirus being the most common cause of gastroenteritis in the UK. According to the 2009 NICE guidelines, diarrhoea usually lasts for 5-7 days and stops within 2 weeks, while vomiting usually lasts for 1-2 days and stops within 3 days. When assessing hydration status, NICE recommends using normal, dehydrated, or shocked categories instead of the traditional mild, moderate, or severe categories.
Children younger than 1 year, especially those younger than 6 months, infants who were of low birth weight, and those who have passed six or more diarrhoeal stools in the past 24 hours or vomited three times or more in the past 24 hours are at an increased risk of dehydration. Additionally, children who have not been offered or have not been able to tolerate supplementary fluids before presentation, infants who have stopped breastfeeding during the illness, and those with signs of malnutrition are also at risk.
If clinical shock is suspected, children should be admitted for intravenous rehydration. For children without evidence of dehydration, it is recommended to continue breastfeeding and other milk feeds, encourage fluid intake, and discourage fruit juices and carbonated drinks. If dehydration is suspected, give 50 ml/kg low osmolarity oral rehydration solution (ORS) solution over 4 hours, plus ORS solution for maintenance, often and in small amounts. It is also important to continue breastfeeding and consider supplementing with usual fluids, including milk feeds or water, but not fruit juices or carbonated drinks.
In terms of diagnosis, NICE suggests doing a stool culture in certain situations, such as when septicaemia is suspected, there is blood and/or mucous in the stool, or the child is immunocompromised. A stool culture should also be considered if the child has recently been abroad, the diarrhoea has not improved by day 7, or there is uncertainty about the diagnosis of gastroenteritis. Features suggestive of hypernatraemic dehydration include jittery movements, increased muscle tone, hyperreflexia, convulsions, and drowsiness or coma.

A 7-year-old girl presents with diffuse lower limb bone pain and tenderness. Her past medical history and family history are mostly unknown, but she is known to have been malnourished and is currently under the care of social services.
During examination, she appears malnourished and pale, with bossing of her forehead, bowing of her legs, and prominent kyphoscoliosis of her spine. She has a waddling gait when walking, and her weight is below the 2nd centile according to a growth chart.
What radiological feature may be observed given the probable diagnosis?Your Answer: Joint widening
Explanation:Rickets can cause joint widening due to an excess of non-mineralized osteoid at the growth plate. This is consistent with the patient’s symptoms of forehead bossing, bowing of the legs, waddling gait, bone pain, and kyphoscoliosis of the spine. The patient’s malnourishment and pale appearance suggest a possible dietary deficiency of vitamin D, which can lead to inadequate mineralization of developing bones. Ballooning, joint space narrowing, and osteolysis are not associated with rickets and do not explain the patient’s symptoms.
Understanding Rickets: Causes, Symptoms, and Treatment
Rickets is a condition that occurs when bones in developing and growing bodies are inadequately mineralized, resulting in soft and easily deformed bones. This condition is usually caused by a deficiency in vitamin D. In adults, a similar condition called osteomalacia can occur.
There are several factors that can predispose individuals to rickets, including a dietary deficiency of calcium, prolonged breastfeeding, unsupplemented cow’s milk formula, and lack of sunlight. Symptoms of rickets include aching bones and joints, lower limb abnormalities such as bow legs or knock knees, swelling at the costochondral junction (known as the rickety rosary), kyphoscoliosis, and soft skull bones in early life (known as craniotabes).
To diagnose rickets, doctors may perform tests to measure vitamin D levels, serum calcium levels, and alkaline phosphatase levels. Treatment for rickets typically involves oral vitamin D supplementation.
In summary, rickets is a condition that affects bone development and can lead to soft and easily deformed bones. It is caused by a deficiency in vitamin D and can be predisposed by several factors. Symptoms include bone and joint pain, limb abnormalities, and swelling at the costochondral junction. Treatment involves oral vitamin D supplementation.

A 6-week-old infant is experiencing projectile vomiting following feeds. The vomit is abundant but not bile-tinged and happens shortly after a feed. During examination, a small mass in the pylorus can be felt. What electrolyte abnormality is most likely to be observed in this baby?
Your Answer: Hypochloremic hypokalaemic metabolic alkalosis
Explanation:The infant is suffering from pyloric stenosis, which leads to a typical imbalance of electrolytes and acid-base known as hypochloremic, hypokalaemic metabolic alkalosis. The continuous vomiting results in a gradual loss of fluids that contain hydrochloric acid, causing the kidneys to retain hydrogen ions over potassium. If the illness is brief, there may not be any electrolyte abnormalities.
Understanding Pyloric Stenosis
Pyloric stenosis is a condition that usually occurs in infants between the second and fourth weeks of life. However, in rare cases, it may present later, up to four months. This condition is caused by the thickening of the circular muscles of the pylorus. Pyloric stenosis is more common in males, with an incidence of 4 per 1,000 live births. It is also more likely to affect first-borns and infants with a positive family history.
The most common symptom of pyloric stenosis is projectile vomiting, which usually occurs about 30 minutes after a feed. Other symptoms may include constipation, dehydration, and a palpable mass in the upper abdomen. Prolonged vomiting can lead to hypochloraemic, hypokalaemic alkalosis, which can be life-threatening.
Diagnosis of pyloric stenosis is typically made using ultrasound. Management of this condition involves a surgical procedure called Ramstedt pyloromyotomy. This procedure involves making a small incision in the pylorus to relieve the obstruction and allow for normal passage of food. With prompt diagnosis and treatment, infants with pyloric stenosis can make a full recovery.

A female infant is born prematurely at 32 weeks gestation by emergency cesarean section. She initially appears to be stable. However, over the ensuing 48 hours she develops worsening neurological function. What is the most probable cause of this deterioration?
Your Answer: Intraventricular haemorrhage
Explanation:Understanding Intraventricular Haemorrhage
Intraventricular haemorrhage is a rare condition that involves bleeding into the ventricular system of the brain. While it is typically associated with severe head injuries in adults, it can occur spontaneously in premature neonates. In fact, the majority of cases occur within the first 72 hours after birth. The exact cause of this condition is not well understood, but it is believed to be a result of birth trauma and cellular hypoxia in the delicate neonatal central nervous system.
Treatment for intraventricular haemorrhage is largely supportive, as therapies such as intraventricular thrombolysis and prophylactic cerebrospinal fluid drainage have not been shown to be effective. However, if hydrocephalus and rising intracranial pressure occur, shunting may be necessary. It is important for healthcare professionals to be aware of this condition and its potential complications in order to provide appropriate care for affected patients.

A 3-year-old girl is brought to the emergency department after experiencing a seizure. Once she is observed and tested, she is diagnosed with febrile convulsions. What advice should be given to her parents before they take her home?
Your Answer: If the seizure lasts longer than 5 minutes, they should call an ambulance
Explanation:Paracetamol is commonly used to treat fever and pain in children. While there is a small chance of developing epilepsy, the risk is minimal. Additionally, there is no proof that paracetamol reduces the likelihood of future seizures.
Febrile convulsions are seizures caused by fever in children aged 6 months to 5 years. They typically last less than 5 minutes and are most commonly tonic-clonic. There are three types: simple, complex, and febrile status epilepticus. Children who have had a first seizure or any features of a complex seizure should be admitted to pediatrics. Regular antipyretics do not reduce the chance of a febrile seizure occurring. The overall risk of further febrile convulsion is 1 in 3, with risk factors including age of onset, fever duration, family history, and link to epilepsy. Children without risk factors have a 2.5% risk of developing epilepsy, while those with all three features have a much higher risk.

A 14-year-old boy presents to the emergency department with his parents complaining of sudden onset right-sided groin pain and inability to bear weight after a fall. On examination, he has a decreased range of motion and an antalgic gait. His heart rate is 96 bpm, blood pressure is 118/76 mmHg, BMI is 31 kg/m², and he is afebrile. What is the most probable finding on examination for this diagnosis?
Your Answer: Reduced internal rotation of the leg in flexion
Explanation:Slipped capital femoral epiphysis (SCFE) often results in a loss of internal rotation of the leg in flexion. This is likely the case for a boy with obesity aged between 10-15 years who is experiencing acute-onset right-sided groin pain and inability to weight bear following potential trauma. Attempting to internally rotate the leg while the hip is flexed would be limited in SCFE due to the anterior and external rotation of the femoral metaphysis. Therefore, reduced internal rotation of the leg in flexion is the correct option. Reduced external rotation of the leg in extension, reduced external rotation of the leg in flexion, and reduced internal rotation of the leg in extension are all incorrect options as they do not align with the typical presentation of SCFE.
Slipped Capital Femoral Epiphysis: A Rare Hip Condition in Children
Slipped capital femoral epiphysis, also known as slipped upper femoral epiphysis, is a rare hip condition that primarily affects children between the ages of 10 and 15. It is more commonly seen in obese boys. This condition is characterized by the displacement of the femoral head epiphysis postero-inferiorly, which may present acutely following trauma or with chronic, persistent symptoms.
The most common symptoms of slipped capital femoral epiphysis include hip, groin, medial thigh, or knee pain and loss of internal rotation of the leg in flexion. In some cases, a bilateral slip may occur. Diagnostic imaging, such as AP and lateral (typically frog-leg) views, can confirm the diagnosis.
The management of slipped capital femoral epiphysis typically involves internal fixation, which involves placing a single cannulated screw in the center of the epiphysis. However, if left untreated, this condition can lead to complications such as osteoarthritis, avascular necrosis of the femoral head, chondrolysis, and leg length discrepancy.
In summary, slipped capital femoral epiphysis is a rare hip condition that primarily affects children, especially obese boys. It is characterized by the displacement of the femoral head epiphysis postero-inferiorly and can present with various symptoms. Early diagnosis and management are crucial to prevent complications.

A 16-year-old girl is brought to the Emergency Department after overdosing on alcohol and paracetamol. She was discovered by her friend, unconscious in a local park, after sending a concerning text message. Her parents were both at work at the time. Upon regaining consciousness, she expresses embarrassment and explains that she had an argument with her boyfriend, now regrets her actions, and wishes to return home. All of her blood tests come back normal and she is deemed medically stable.
What is the best course of immediate action for her management?Your Answer: Admit onto the paediatric ward to await an urgent Child and Adolescent Mental Health Services (CAMHS) assessment prior to discharge
Explanation:Options for Discharging a Child with Suicidal Ideation
When a child presents with suicidal ideation, it is important to carefully consider the best course of action for their safety and well-being. Here are some options for discharging a child with suicidal ideation:
1. Admit onto the paediatric ward to await an urgent Child and Adolescent Mental Health Services (CAMHS) assessment prior to discharge.
2. Start fluoxetine 10 mg and discharge home. However, antidepressants should only be considered following full assessment and recommendation by a child and adolescent psychiatrist.
3. Discharge home with outpatient CAMHS follow up within a week. This option is only appropriate if the child is not at high risk of deliberate self-harm/attempted suicide.
4. Discharge home with advice to book an urgent appointment to see their GP the same day. This option is only appropriate if the child is not at high risk of deliberate self-harm/attempted suicide.
5. Start citalopram 10 mg and discharge home. However, antidepressants should only be considered following full assessment and recommendation by a child and adolescent psychiatrist.
It is important to prioritize the safety and well-being of the child and consult with mental health professionals before making any decisions about discharge.

A 6-year-old child comes to the Emergency Department (ED) after running into a door while playing with his older brother. He cried and screamed initially, but fell asleep about an hour later. Upon waking up, he vomited twice. During the examination, a 3 cm x 4 cm swelling is observed on his forehead. The central nervous system (CNS) and peripheral nervous system (PNS) examination are generally normal, as are his eyes. His cervical spine is also normal. While in the examination room, he vomits again. What is the best course of action?
Your Answer: Observe him closely for at least 4 hours (after the injury)
Explanation:Guidelines for Management of Head Injuries in Children: Observation and CT Scans
Children are at a higher risk for head injuries, which can lead to contusion and intracerebral hemorrhage. However, CT scans can also cause radiation-related brain damage and increase the risk of malignancy. Therefore, it is crucial to conduct a detailed assessment and balance the risks and benefits before deciding on investigation and management. The National Institute for Health and Care Excellence (NICE) has provided clear guidelines for head injuries in children.
Observation and CT scans are necessary for children who have had a head injury and have more than one of the following features: loss of consciousness for more than 5 minutes, abnormal drowsiness, three or more episodes of vomiting, a dangerous mechanism/high-impact injury, or amnesia for more than 5 minutes. If they have only one of these features, they should be observed for at least 4 hours.
CT scans should be performed within 1 hour for children with risk factors such as suspicion of non-accidental injury, post-traumatic seizure, GCS less than 14, or presence of a skull fracture or basal skull fracture. A provisional written radiology report should be made available within 1 hour of the scan being performed.
If a child has only one of the risk factors mentioned above, they should be observed for a minimum of 4 hours. If any of the risk factors occur during observation, a CT scan should be performed within 1 hour.
It is important to note that child protection is crucial, but there are no features in the case history that suggest non-accidental injury. Therefore, speaking to social services may not be necessary.

A 3-month-old girl is presented to the pediatrician by her father. The baby has been struggling with feeding since birth, is frequently fussy, and her lips turn blue after crying for extended periods. She was born at term, weighing 2500 grams. During the examination, the doctor detects an ejection systolic murmur at the left sternal edge.
What is the probable diagnosis?Your Answer: Tetralogy of Fallot
Explanation:Tetralogy of Fallot is characterized by cyanosis or collapse within the first month of life, as well as hypercyanotic spells and an ejection systolic murmur at the left sternal edge. The presence of poor feeding, agitation, and low birth weight also suggest this diagnosis. It’s important to note that the murmur is caused by pulmonary stenosis, not the ventricular septal defect, which is too large to produce a murmur. An atrial septal defect and patent ductus arteriosus are unlikely as they are acyanotic shunts that produce different symptoms and sounds on auscultation. Transposition of the great arteries is also not a possibility as it presents with different symptoms immediately after delivery.
Understanding Tetralogy of Fallot
Tetralogy of Fallot (TOF) is a congenital heart disease that results from the anterior malalignment of the aorticopulmonary septum. It is the most common cause of cyanotic congenital heart disease, and it typically presents at around 1-2 months, although it may not be detected until the baby is 6 months old. The condition is characterized by four features, including ventricular septal defect (VSD), right ventricular hypertrophy, right ventricular outflow tract obstruction, and overriding aorta. The severity of the right ventricular outflow tract obstruction determines the degree of cyanosis and clinical severity.
Other features of TOF include cyanosis, which may cause episodic hypercyanotic ‘tet’ spells due to near occlusion of the right ventricular outflow tract. These spells are characterized by tachypnea and severe cyanosis that may occasionally result in loss of consciousness. They typically occur when an infant is upset, in pain, or has a fever, and they cause a right-to-left shunt. Additionally, TOF may cause an ejection systolic murmur due to pulmonary stenosis, and a right-sided aortic arch is seen in 25% of patients. Chest x-ray shows a ‘boot-shaped’ heart, while ECG shows right ventricular hypertrophy.
The management of TOF often involves surgical repair, which is usually undertaken in two parts. Cyanotic episodes may be helped by beta-blockers to reduce infundibular spasm. However, it is important to note that at birth, transposition of the great arteries is the more common lesion as patients with TOF generally present at around 1-2 months. Understanding the features and management of TOF is crucial for healthcare professionals to provide appropriate care and treatment for affected infants.

You are a junior doctor in paediatrics. You are called to attend an emergency Caesarean section for a baby at 32 weeks’ gestation due to fetal distress. The baby is delivered and does not cry immediately. The cord is cut, and the baby is dried and placed on the Resuscitaire®. There is no spontaneous respiratory effort from the baby who is pale and floppy, with a heart rate of 30 bpm.
When would it be appropriate to start chest compressions in a premature neonate?Your Answer: After a total of ten inflation breaths and 30 seconds of effective ventilation breaths if the baby’s heart rate is < 60 bpm
Correct Answer:
Explanation:Neonatal Resuscitation Guidelines for Heart Rate and Ventilation
In neonatal resuscitation, it is important to follow guidelines for heart rate and ventilation to ensure the best possible outcome for the baby. Here are the guidelines for different scenarios:
– After a total of ten inflation breaths and 30 seconds of effective ventilation breaths if the baby’s heart rate is < 60 bpm: Chest compressions are indicated at a ratio of 3:1 (compression:ventilation). The heart rate should be checked every 30 seconds. If the heart rate is not detectable or very slow (<60), consider venous access and drugs.
– After ten inflation breaths if the baby’s heart rate is < 120 bpm: Give 30 seconds of effective ventilation breaths before starting compressions if the heart rate is < 60 bpm.
– After five inflation breaths if the baby is not spontaneously breathing: Ventilate for 30 seconds before starting compressions, unless there is an underlying cardiac cause for the cardiorespiratory arrest.
– After ten inflation breaths and two minutes of effective ventilation breaths if the baby’s heart rate is < 60 bpm: This scenario is not applicable as compressions should have been started after the initial 30 seconds of ventilation.
– Before any inflation breaths if the baby’s heart rate is < 60 bpm: Give 30 seconds of effective ventilation breaths before starting compressions if ten inflation breaths are not successful and the heart rate is still < 60 bpm. -

A 4-year-old boy is brought to the paediatric assessment unit by his parents after they witnessed him having a seizure. He had been experiencing a fever and cold symptoms for the past three days. His father also noticed a rash on his chest and a swollen tongue yesterday. The boy has met all of his developmental milestones prior to this incident.
After being assessed, the medical team has determined that the boy is safe to go home. What advice should the parents be given?Your Answer: An ambulance must be called if another seizure occurs and persists for longer than five minutes
Explanation:Parents should be informed that if a febrile convulsion lasts longer than five minutes, they should call an ambulance. The presence of a sandpaper rash and strawberry tongue in the vignette suggests a diagnosis of scarlet fever, which is often associated with febrile seizures. However, it is important to note that simple febrile seizures lasting only a few minutes are generally not a cause for concern. It is not recommended to prescribe prophylactic antipyretics as they have not been shown to reduce seizure frequency according to NICE guidelines. Referral to a paediatric neurologist is only necessary if the child has neurodevelopmental delay or signs of a neurocutaneous syndrome or metabolic disorder.
Febrile convulsions are seizures caused by fever in children aged 6 months to 5 years. They typically last less than 5 minutes and are most commonly tonic-clonic. There are three types: simple, complex, and febrile status epilepticus. Children who have had a first seizure or any features of a complex seizure should be admitted to pediatrics. Regular antipyretics do not reduce the chance of a febrile seizure occurring. The overall risk of further febrile convulsion is 1 in 3, with risk factors including age of onset, fever duration, family history, and link to epilepsy. Children without risk factors have a 2.5% risk of developing epilepsy, while those with all three features have a much higher risk.

A 2-year-old boy is presented to an urgent GP appointment with an acute limp. He has a runny nose but no fever. There is no reported injury. He is able to bear weight on the affected leg.
What is the appropriate course of action?Your Answer: Urgent specialist assessment
Explanation:A child under the age of 3 who presents with an acute limp requires urgent specialist assessment. This is because septic arthritis is more common than transient synovitis in this age group. A routine paediatric referral is not appropriate as the concern is ruling out septic arthritis, which requires urgent attention. An urgent X-ray or hip ultrasound scan is also not sufficient, as a comprehensive specialist examination is necessary to exclude serious pathology.
Causes of Limping in Children
Limping in children can be caused by various factors, which may differ depending on the child’s age. One possible cause is transient synovitis, which has an acute onset and is often accompanied by viral infections. This condition is more common in boys aged 2-12 years. On the other hand, septic arthritis/osteomyelitis may cause a child to feel unwell and have a high fever. Juvenile idiopathic arthritis may cause a painless limp, while trauma can usually be diagnosed through the child’s history. Development dysplasia of the hip is usually detected in neonates and is six times more common in girls. Perthes disease, which is due to avascular necrosis of the femoral head, is more common in children aged 4-8 years. Finally, slipped upper femoral epiphysis may occur in children aged 10-15 years and is characterized by the displacement of the femoral head epiphysis postero-inferiorly. It is important to identify the cause of a child’s limp in order to provide appropriate treatment and prevent further complications.

A 6-year-old boy visits his GP with a productive cough and wheeze. During the examination, a 1/6 intensity systolic murmur is detected in the second intercostal space lateral to the left sternal edge. The murmur is not audible when the child lies flat. What is the most probable diagnosis?
Your Answer: Innocent murmur
Explanation:The innocent murmur is the correct answer. It is characterized by being soft, systolic, short, symptomless, and varying with position when standing or sitting. In contrast, coarctation of the aorta produces an ejection systolic murmur that can be heard through to the back and does not change with position. This condition is also associated with hypertension in the upper extremities and a difference in blood pressure between the arms and legs. Ventricular septal defect presents as a pansystolic murmur, while atrial septal defect is an ejection systolic murmur that is often accompanied by fixed splitting of the 2nd heart sound.
Innocent murmurs are common in children and are usually harmless. There are different types of innocent murmurs, including ejection murmurs, venous hums, and Still’s murmur. Ejection murmurs are caused by turbulent blood flow at the outflow tract of the heart, while venous hums are due to turbulent blood flow in the great veins returning to the heart. Still’s murmur is a low-pitched sound heard at the lower left sternal edge.
An innocent ejection murmur is characterized by a soft-blowing murmur in the pulmonary area or a short buzzing murmur in the aortic area. It may vary with posture and is localized without radiation. There is no diastolic component, no thrill, and no added sounds such as clicks. The child is usually asymptomatic, and there are no other abnormalities.
Overall, innocent murmurs are not a cause for concern and do not require treatment. However, if a child has symptoms such as chest pain, shortness of breath, or fainting, further evaluation may be necessary to rule out any underlying heart conditions.

What is the most common age for the presentation of hereditary multiple exostosis (osteochondroma)?
Your Answer: 10 years - 25 years
Explanation:Multiple Exostosis or Osteochondromas
Multiple exostosis or osteochondromas are typically seen in early adulthood, although they are believed to be congenital lesions that arise from displaced or abnormal growth plate cartilage. These growths may also occur in children with open growth plates who have been exposed to radiation. While spontaneous regression is rare, surgical removal is the preferred treatment option if necessary. Osteochondromas are most commonly found in the metaphysis of long bones, but they can also occur in any bone that develops through endochondral bone formation.

A 4-year-old boy is brought to his pediatrician by his father. He has been experiencing a dry cough and runny nose for the past 7 days, along with a 6-day history of fevers up to 38.7ºC that have not responded to paracetamol and ibuprofen.
During the examination, the boy appears generally unwell and unhappy. His tongue is bright red, and there is a maculopapular rash on his trunk. Bilateral conjunctival injection is present, but there is no apparent discharge. Additionally, palpable submandibular lymphadenopathy is observed.
What investigation should be utilized to screen for long-term complications, given the probable diagnosis?Your Answer: Echocardiogram
Explanation:An echocardiogram should be used to screen for coronary artery aneurysms, which are a complication of Kawasaki disease. To diagnose Kawasaki disease, a child must have a fever for at least 5 days and meet 4 out of 5 diagnostic criteria, including oropharyngeal changes, changes in the peripheries, bilateral non purulent conjunctivitis, polymorphic rash, and cervical lymphadenopathy. This disease is the most common cause of acquired cardiac disease in childhood, and it is important to exclude coronary artery aneurysms. Echocardiograms are a noninvasive and appropriate screening modality for this complication, as they do not expose the child to ionising radiation. Antistreptolysin O antibody titres, CT coronary angiogram, and ECG are not appropriate screening modalities for coronary artery aneurysms associated with Kawasaki disease.
Understanding Kawasaki Disease
Kawasaki disease is a rare type of vasculitis that primarily affects children. It is important to identify this disease early on as it can lead to serious complications, such as coronary artery aneurysms. The disease is characterized by a high-grade fever that lasts for more than five days and is resistant to antipyretics. Other symptoms include conjunctival injection, bright red, cracked lips, strawberry tongue, cervical lymphadenopathy, and red palms and soles that later peel.
Diagnosis of Kawasaki disease is based on clinical presentation as there is no specific diagnostic test available. Management of the disease involves high-dose aspirin, which is one of the few indications for aspirin use in children. Intravenous immunoglobulin is also used as a treatment option. Echocardiogram is the initial screening test for coronary artery aneurysms, rather than angiography.
Complications of Kawasaki disease can be serious, with coronary artery aneurysm being the most common. It is important to recognize the symptoms of Kawasaki disease early on and seek medical attention promptly to prevent potential complications.

During the baby check of Maya, a 4-day-old neonate delivered via Caesarean section due to a breech position, both Barlows and Ortolani's tests are negative. What should be the next best step?
Your Answer: Perform a bilateral hip ultrasound at 4-6 weeks
Explanation:The Importance of Bilateral Hip Ultrasound in Newborns with Risk Factors for Developmental Dysplasia of the Hip
Babies with risk factors for developmental dysplasia of the hip require further investigation even if they test negative on Barlows and Ortolani’s tests. National guidelines recommend a bilateral hip ultrasound at 4-6 weeks for these infants. If the Barlow’s or Ortolani’s tests are abnormal, a scan should be done within 2 weeks. In cases where the baby was in the breech position at term but had negative test results, a hip ultrasound is still necessary. It is important to reassure parents that this is a normal procedure and that no treatment may be necessary. Bilateral hip radiographs are not useful in neonates and MRI is not used in the diagnosis of developmental dysplasia of the hip. Operative approaches are only recommended for patients over 18 months of age, and conservative approaches are preferred for younger children.

You are reviewing a 12-hour-old neonate on the Postnatal Ward. During your examination, you notice a swelling over the occipital region of the skull. It is soft and does not appear tender. On further examination, you feel that the swelling is crossing the cranial sutures. Neurologically, the child appears normal. She was born by forceps due to failure to progress. There is no family history of note.
What is the most appropriate initial investigation?Your Answer: Cranial ultrasound scan
Explanation:Investigations for Cranial Swellings in Neonates
Cranial swellings in neonates can be a cause for concern, and prompt investigation is necessary to rule out serious conditions such as subgaleal haemorrhage. The following are some common investigations used to diagnose cranial swellings in neonates:
Cranial Ultrasound Scan
This is the investigation of choice and can be done quickly and safely by Neonatal Consultants and most Paediatric Registrars on Neonatal placement. The scan can provide a significant amount of information, and the key finding to look for is whether the swelling crosses the cranial suture lines. If it does, this should be a cause for concern as it may indicate subgaleal haemorrhage.Cerebral Function Monitoring
This investigation is used to monitor a neonate’s neurological state and identify seizure activity. However, it is not necessary in cases where the baby appears neurologically normal, as in the case of cranial swellings.Cranial Computed Tomography (CT) Scan
This investigation exposes the baby to unnecessary radiation and is not recommended as the first choice. If the findings from the cranial ultrasound scan are unclear, an MRI scan is the next investigation of choice.Cranial Magnetic Resonance Imaging (MRI) Scan
This investigation is not the first choice and is only done after a cranial ultrasound scan. It provides detailed information about the cranial swelling and can help diagnose conditions such as subgaleal haemorrhage.Liver Function Tests
Liver function tests are not part of the initial workup for cranial swellings. However, they may be done at some point during admission for other reasons, such as the risk of jaundice secondary to possible extra-/intracranial haemorrhage. -

A 7-year-old girl is brought to the pediatrician by her father. She has been experiencing coryza and a fever of 38C for the past 3 days. This morning her father noticed a red rash on both cheeks and pallor surrounding her mouth. What is the most probable organism responsible for these symptoms?
Your Answer: Parvovirus B19
Explanation:The cause of the boy’s symptoms, which include a red rash following coryza and fever, is erythema infectiosum, also known as slapped-cheek syndrome. This infection is caused by parvovirus b19, a common organism responsible for childhood infections.
The table provides information on various childhood infections including chickenpox, measles, mumps, rubella, erythema infectiosum, scarlet fever, and hand, foot and mouth disease. Each infection has its own unique features such as fever, rash, and systemic upset. Chickenpox starts with fever and an itchy rash that spreads from the head and trunk. Measles has a prodrome of irritability and conjunctivitis, followed by a rash that starts behind the ears and spreads to the whole body. Mumps causes fever, malaise, and parotitis. Rubella has a pink maculopapular rash that starts on the face and spreads to the whole body, along with suboccipital and postauricular lymphadenopathy. Erythema infectiosum, also known as fifth disease, causes lethargy, fever, and a slapped-cheek rash. Scarlet fever is a reaction to erythrogenic toxins produced by Group A haemolytic streptococci and causes fever, malaise, tonsillitis, and a rash with fine punctate erythema. Hand, foot and mouth disease causes mild systemic upset, sore throat, and vesicles in the mouth and on the palms and soles of the feet.

A 5-year-old girl is seen by the orthopaedic specialist after experiencing a worsening limp for 4 weeks. Her blood tests were normal, and x-rays revealed a hip joint effusion without any significant femoral head structural abnormalities. The doctor diagnosed her with Perthes' disease. What would be the most suitable initial management plan for this child?
Your Answer: Observation
Explanation:If Perthes’ disease is diagnosed in children under the age of 6 years and there is no significant collapse of the femoral head or gross structural abnormalities, observation is the recommended course of action. This involves regular x-rays, monitoring, and physiotherapy. The Pavlik harness, serial casting, and steroid injections are not appropriate treatments for this condition.
Understanding Perthes’ Disease
Perthes’ disease is a degenerative condition that affects the hip joints of children, typically between the ages of 4-8 years. It is caused by a lack of blood supply to the femoral head, which leads to bone infarction and avascular necrosis. This condition is more common in boys, with around 10% of cases being bilateral. The symptoms of Perthes’ disease include hip pain, stiffness, reduced range of hip movement, and a limp. Early changes can be seen on an x-ray, such as widening of the joint space, while later changes include decreased femoral head size and flattening.
To diagnose Perthes’ disease, a plain x-ray is usually sufficient. However, if symptoms persist and the x-ray is normal, a technetium bone scan or magnetic resonance imaging may be necessary. If left untreated, Perthes’ disease can lead to complications such as osteoarthritis and premature fusion of the growth plates.
The severity of Perthes’ disease is classified using the Catterall staging system, which ranges from stage 1 (clinical and histological features only) to stage 4 (loss of acetabular integrity). Treatment options include keeping the femoral head within the acetabulum using a cast or braces, observation for children under 6 years old, and surgical management for older children with severe deformities. The prognosis for Perthes’ disease is generally good, with most cases resolving with conservative management. Early diagnosis is key to improving outcomes.

You assist in the delivery of a newborn in the neonatal unit. At 5 minutes, the baby's heart rate is 120 bpm, the baby is crying vigorously with active movement in all extremities. The baby is coughing and sneezing. The body is pink but the hands and feet are slightly blue and cool to the touch. Determine the APGAR score.
Your Answer: 9
Explanation:The Apgar score is a tool used to evaluate the health of a newborn baby. It is recommended by NICE to be assessed at 1 and 5 minutes after birth, and again at 10 minutes if the initial score is low. The score is based on five factors: pulse, respiratory effort, color, muscle tone, and reflex irritability. A score of 0-3 is considered very low, 4-6 is moderate low, and 7-10 indicates that the baby is in good health. The score helps healthcare professionals quickly identify any potential issues and provide appropriate care.

Each one of the following statements regarding ADHD is correct, except:
Your Answer: The majority of children have normal or increased intelligence
Explanation:Understanding Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects social interaction, communication, and behaviour. It is usually diagnosed during early childhood, but symptoms may manifest later. ASD can occur in individuals with any level of intellectual ability, and its manifestations range from subtle problems to severe disabilities. The prevalence of ASD has increased over time due to changes in definitions and increased awareness, with recent estimates suggesting a prevalence of 1-2%. Boys are three to four times more likely to be diagnosed with ASD than girls, and around 50% of children with ASD have an intellectual disability.
Individuals with ASD may exhibit a broad range of clinical manifestations, including impaired social communication and interaction, repetitive behaviours, interests, and activities, and associated conditions such as attention deficit hyperactivity disorder and epilepsy. Although there is no cure for ASD, early diagnosis and intensive educational and behavioural management can improve outcomes. Treatment involves a comprehensive approach that includes non-pharmacological therapies such as early educational and behavioural interventions, pharmacological interventions for associated conditions, and family support and counselling. The goal of treatment is to increase functional independence and quality of life for individuals with ASD.

A 3-month-old infant with Down's syndrome is presented to the GP by his parents due to their worry about his occasional episodes of turning blue and rapid breathing, especially when he is upset or in pain. These episodes have caused him to faint twice. The parents also mention that he has a congenital heart defect. What is the likely diagnosis based on this history?
Your Answer: Tetralogy of Fallot
Explanation:Understanding Tetralogy of Fallot
Tetralogy of Fallot (TOF) is a congenital heart disease that results from the anterior malalignment of the aorticopulmonary septum. It is the most common cause of cyanotic congenital heart disease, and it typically presents at around 1-2 months, although it may not be detected until the baby is 6 months old. The condition is characterized by four features, including ventricular septal defect (VSD), right ventricular hypertrophy, right ventricular outflow tract obstruction, and overriding aorta. The severity of the right ventricular outflow tract obstruction determines the degree of cyanosis and clinical severity.
Other features of TOF include cyanosis, which may cause episodic hypercyanotic ‘tet’ spells due to near occlusion of the right ventricular outflow tract. These spells are characterized by tachypnea and severe cyanosis that may occasionally result in loss of consciousness. They typically occur when an infant is upset, in pain, or has a fever, and they cause a right-to-left shunt. Additionally, TOF may cause an ejection systolic murmur due to pulmonary stenosis, and a right-sided aortic arch is seen in 25% of patients. Chest x-ray shows a ‘boot-shaped’ heart, while ECG shows right ventricular hypertrophy.
The management of TOF often involves surgical repair, which is usually undertaken in two parts. Cyanotic episodes may be helped by beta-blockers to reduce infundibular spasm. However, it is important to note that at birth, transposition of the great arteries is the more common lesion as patients with TOF generally present at around 1-2 months. Understanding the features and management of TOF is crucial for healthcare professionals to provide appropriate care and treatment for affected infants.

A 4-year-old girl is under your review for idiopathic constipation treatment with Movicol Paediatric Plain. Despite her mother increasing the dose, there has been no improvement. The child is in good health and abdominal examination is unremarkable. What would be the most suitable course of action to take next?
Your Answer: Add senna
Explanation:Understanding and Managing Constipation in Children
Constipation is a common problem in children, with the frequency of bowel movements decreasing as they age. The National Institute for Health and Care Excellence (NICE) has provided guidelines for the diagnosis and management of constipation in children. A diagnosis of constipation is suggested by two or more symptoms, including infrequent bowel movements, hard stools, and associated distress or pain. Most cases of constipation in children are idiopathic, but other causes such as dehydration, low-fiber diet, and medication use should be considered and excluded.
If a diagnosis of constipation is made, NICE recommends assessing for faecal impaction before starting treatment. Treatment for faecal impaction involves using polyethylene glycol 3350 + electrolytes (Movicol Paediatric Plain) as the first-line treatment, with the addition of a stimulant laxative if necessary. Maintenance therapy involves a similar regime, with adjustments to the starting dose and the addition of other laxatives if necessary.
It is important to note that dietary interventions alone are not recommended as first-line treatment, although ensuring adequate fluid and fiber intake is important. Regular toileting and non-punitive behavioral interventions should also be considered. For infants, extra water, gentle abdominal massage, and bicycling the legs can be helpful for constipation. If these measures are not effective, lactulose can be added.
In summary, constipation in children can be managed effectively with a combination of medication, dietary adjustments, and behavioral interventions. It is important to follow NICE guidelines and consider the individual needs of each child.

A 6-year-old girl is brought to the Emergency Department by her parents. She has been experiencing pain in her left hip for the past two weeks and has been limping. Upon examination, there is a slight decrease in the range of motion in her left hip joint, but no signs of swelling or effusion. Her right hip appears normal. Blood tests, including cultures, are negative. What is the most suitable initial management option for the underlying diagnosis?
Your Answer: Reassurance and follow-up
Explanation:Perthes’ disease is a condition that affects the hip joints of children, typically between the ages of 4 and 8. It is more common in boys and presents with symptoms such as hip pain, limping, and reduced range of motion. However, if Perthes’ disease occurs in children under the age of 6, it has a good prognosis and can be managed with observation and follow-up. Therefore, this is the preferred management choice. Open reduction and internal fixation, splinting, and the use of a Pavlik harness are not appropriate treatments for Perthes’ disease in children under 6 years old.

A 10-year-old girl is brought to the Accident and Emergency department by her parents. On a background of high-grade fever and lethargy over the last 12 hours, the child had an episode of jerking of the limbs, frothing at the mouth and incontinence of urine. She has failed to recover full consciousness after the episode. At presentation, she is poorly responsive to name-calling, but responsive to pain. She is however maintaining her airway and oxygen saturation is 95% on air. Limited neurological examination is unremarkable. Non-contrast computerised tomography (CT) scan of the brain is normal. Lumbar puncture is performed and reveals a slightly raised opening pressure, moderately increased cerebrospinal fluid (CSF) protein, CSF lymphocytosis and normal glucose.
What is the most important step in management?Your Answer: IV acyclovir
Explanation:The child in question is suffering from viral encephalitis, which is typically treated with IV acyclovir. The recommended dosage is 5 mg/kg every 8 hours for 5 days, or 10 mg/kg every 8 hours for at least 14 days in cases of encephalitis. Encephalitis should be suspected when a patient presents with altered behavior, decreased consciousness, focal neurology, or seizures, along with a viral prodrome of fever and lethargy. The most common cause of encephalitis is the herpes simplex virus-1 (HSV-1), with other common causes including cytomegalovirus (CMV), Epstein-Barr virus (EBV), and Japanese encephalitis. Diagnostic tests should include a full blood count, urea and electrolytes, inflammatory markers, blood glucose, blood cultures, and serum for viral polymerase chain reaction (PCR). A CT scan of the brain is necessary to rule out structural brain lesions and raised intracranial pressure. Lumbar puncture is then performed. Mortality in untreated viral encephalitis is high, so IV acyclovir should be started within 30 minutes of the patient arriving. Intubation and ventilation may be necessary in severe cases, but in this case, acyclovir is the most appropriate treatment. While MRI may aid in diagnosis, CSF analysis is sufficient, and IV cefotaxime and IV mannitol are not the most urgent steps in management.

A 5-year-old girl is brought to the Emergency Department by her father who is concerned about her recent limp. She had a cold recently, but is otherwise healthy and has not experienced any injuries. The child has met all developmental milestones and there were no complications during pregnancy or birth. What is the probable reason for her current condition?
Your Answer: Transient synovitis
Explanation:Transient synovitis, also known as irritable hip, is a common cause of hip pain in children aged 3-8 years. It typically occurs following a recent viral infection and presents with symptoms such as groin or hip pain, limping or refusal to weight bear, and occasionally a low-grade fever. However, a high fever may indicate other serious conditions such as septic arthritis, which requires urgent specialist assessment. To exclude such diagnoses, NICE Clinical Knowledge Summaries recommend monitoring children in primary care with a presumptive diagnosis of transient synovitis, provided they are aged 3-9 years, well, afebrile, mobile but limping, and have had symptoms for less than 72 hours. Treatment for transient synovitis involves rest and analgesia, as the condition is self-limiting.

You are a healthcare professional at the paediatric oncology unit and you have been summoned to speak with the parents of a 6-year-old boy who has recently been diagnosed with acute lymphoblastic leukaemia (ALL). The parents are anxious about their older daughter and are wondering if she is also at a higher risk of developing ALL. Can you provide them with information on the epidemiology of acute lymphoblastic leukaemia?
Your Answer: Peak incidence is 2-5 years
Explanation:Childhood leukaemia is the most prevalent cancer in children, without significant familial correlation. However, certain genetic disorders, such as Down’s syndrome, can increase the risk of developing this disease.
Acute lymphoblastic leukaemia (ALL) is a type of cancer that commonly affects children and accounts for 80% of childhood leukaemias. It is most prevalent in children between the ages of 2-5 years, with boys being slightly more affected than girls. Symptoms of ALL can be divided into those caused by bone marrow failure, such as anaemia, neutropaenia, and thrombocytopenia, and other features like bone pain, splenomegaly, and hepatomegaly. Fever is also present in up to 50% of new cases, which may indicate an infection or a constitutional symptom. Testicular swelling may also occur.
There are three types of ALL: common ALL, T-cell ALL, and B-cell ALL. Common ALL is the most common type, accounting for 75% of cases, and is characterized by the presence of CD10 and a pre-B phenotype. Poor prognostic factors for ALL include age less than 2 years or greater than 10 years, a white blood cell count greater than 20 * 109/l at diagnosis, T or B cell surface markers, non-Caucasian ethnicity, and male sex.

An emergency call is made for a 10-year-old boy who has collapsed in the waiting room. The receptionists have already called 999. After 10 seconds, there are no signs of respiration and the boy does not respond to stimulation. There is no apparent foreign object in his mouth. What should be the next appropriate action?
Your Answer: Give 5 rescue breaths
Explanation:The current guidelines for paediatric basic life support still prioritize rescue breaths, despite the shift in focus for adult cases. This is because most cases of paediatric cardiac arrest are caused by issues with the airway or breathing. It is recommended to administer 5 rescue breaths if the child shows no signs of breathing during initial assessment.
Paediatric Basic Life Support Guidelines
Paediatric basic life support guidelines were updated in 2015 by the Resuscitation Council. Lay rescuers should use a compression:ventilation ratio of 30:2 for children under 1 year and between 1 year and puberty, a child is defined. If there are two or more rescuers, a ratio of 15:2 should be used.
The algorithm for paediatric basic life support starts with checking if the child is unresponsive and shouting for help. The airway should be opened, and breathing should be checked by looking, listening, and feeling for breaths. If the child is not breathing, five rescue breaths should be given, and signs of circulation should be checked.
For infants, the brachial or femoral pulse should be used, while children should use the femoral pulse. Chest compressions should be performed at a ratio of 15:2, with a rate of 100-120 compressions per minute for both infants and children. The depth of compressions should be at least one-third of the anterior-posterior dimension of the chest, which is approximately 4 cm for an infant and 5 cm for a child.
In children, the lower half of the sternum should be compressed, while in infants, a two-thumb encircling technique should be used for chest compressions. These guidelines are crucial for anyone who may need to perform basic life support on a child, and it is essential to follow them carefully to ensure the best possible outcome.

A two-hour-old baby born at 38+5 weeks in the Special Care Baby Unit is exhibiting mild respiratory distress, with subcostal recessions and grunting. The baby's respiratory rate is 68/min without any apnoeas, their heart rate is 150 bpm, and their axillary temperature is 36.8ºC. The baby appears pink, with normal pre-post ductal saturations and no additional heart sounds. Fontanelles are normal, and their birth weight is within the normal range.
The chest X-ray shows hyperinflation and a thin fluid line in the right horizontal fissure. What is the most significant risk factor for the likely diagnosis?Your Answer: Caesarean section delivery
Explanation:Transient tachypnoea of the newborn (TTN) is most likely the diagnosis for a baby with mildly raised respiratory rate and increased work of breathing in the hours after labour, with all other observations being normal. Caesarean section delivery is the most important risk factor for TTN, with other risk factors including male gender, birth asphyxia, and gestational diabetes. Breech presentation is not a risk factor for TTN, while meconium in liquor would make meconium aspiration the most likely diagnosis. Fever during vaginal delivery would make other infective differentials more likely, but a sepsis screen would be needed to rule this out before a diagnosis of TTN could be made.
Understanding Transient Tachypnoea of the Newborn
Transient tachypnoea of the newborn (TTN) is a common respiratory condition that affects newborns. It is caused by the delayed resorption of fluid in the lungs, which can lead to breathing difficulties. TTN is more common in babies born via caesarean section, as the fluid in their lungs may not be squeezed out during the birth process. A chest x-ray may show hyperinflation of the lungs and fluid in the horizontal fissure.
The management of TTN involves observation and supportive care. In some cases, supplementary oxygen may be required to maintain oxygen saturation levels. However, TTN usually resolves within 1-2 days. It is important for healthcare professionals to monitor newborns with TTN closely and provide appropriate care to ensure a full recovery. By understanding TTN and its management, healthcare professionals can provide the best possible care for newborns with this condition.

A 4-year-old girl is brought to the emergency department by her father with bruising after a fall. During assessment, it is noted that she has a global developmental delay. She walks with difficulty, has some fine motor skills, and is playing with toys during the consultation. There are bruises on her back, right elbow, and right thigh, at different stages of healing.
Her father reports that these bruises are from her being clumsy for the past few months and he himself once had bruising which required oral steroids and thinks she has developed the same condition.
What would be the most appropriate next step in her management?Your Answer: Immediately contact safeguarding lead
Explanation:The presence of multiple bruises at different stages of healing in an infant who has been brought a few months after the injuries occurred should raise suspicion of non-accidental injury. This is because it is unlikely for a child to have so many bruises from clumsiness alone. A delayed presentation may also suggest non-accidental injury. Therefore, the correct course of action is to immediately contact the safeguarding lead. While coagulation screen and coagulopathy testing may be performed later, they are not the first priority. Similarly, oral prednisolone is not the first-line treatment for children with immune thrombocytopenia (ITP) and is not relevant in this case. The priority is to assess the infant for non-accidental injury.
Recognizing Child Abuse: Signs and Symptoms
Child abuse is a serious issue that can have long-lasting effects on a child’s physical and emotional well-being. It is important to be able to recognize the signs and symptoms of child abuse in order to intervene and protect the child. One possible indicator of abuse is when a child discloses abuse themselves. However, there are other factors that may point towards abuse, such as an inconsistent story with injuries, repeated visits to A&E departments, delayed presentation, and a frightened, withdrawn appearance known as frozen watchfulness.
Physical presentations of child abuse can also be a sign of abuse. These may include bruising, fractures (especially metaphyseal, posterior rib fractures, or multiple fractures at different stages of healing), torn frenulum (such as from forcing a bottle into a child’s mouth), burns or scalds, failure to thrive, and sexually transmitted infections like Chlamydia, gonorrhoeae, and Trichomonas. It is important to be aware of these signs and symptoms and to report any concerns to the appropriate authorities to ensure the safety and well-being of the child.

A 3-year-old girl is presented to the clinic by her mother complaining of ear pain and fever. During the examination of the chest, a murmur is detected. Which of the following features is not in line with an innocent murmur?
Your Answer: Diastolic murmur
Explanation:Innocent murmurs are common in children and are usually harmless. There are different types of innocent murmurs, including ejection murmurs, venous hums, and Still’s murmur. Ejection murmurs are caused by turbulent blood flow at the outflow tract of the heart, while venous hums are due to turbulent blood flow in the great veins returning to the heart. Still’s murmur is a low-pitched sound heard at the lower left sternal edge.
An innocent ejection murmur is characterized by a soft-blowing murmur in the pulmonary area or a short buzzing murmur in the aortic area. It may vary with posture and is localized without radiation. There is no diastolic component, no thrill, and no added sounds such as clicks. The child is usually asymptomatic, and there are no other abnormalities.
Overall, innocent murmurs are not a cause for concern and do not require treatment. However, if a child has symptoms such as chest pain, shortness of breath, or fainting, further evaluation may be necessary to rule out any underlying heart conditions.

A 6 month old infant presents to the hospital with a fever. Upon examination, there are no respiratory symptoms or signs of diarrhea. What initial investigations would you include in your assessment?
Your Answer: Blood culture
Explanation:When evaluating infants under 3 months with a fever, the following tests should be conducted: a complete blood count, blood culture, C-reactive protein test, urine analysis to check for urinary tract infections, and a chest X-ray if respiratory symptoms are present. Additionally, a stool culture should be performed if the infant is experiencing diarrhea.
The NICE Feverish illness in children guidelines were introduced in 2007 and updated in 2013. These guidelines use a ‘traffic light’ system to assess the risk of children under 5 years old presenting with a fever. It is important to note that these guidelines only apply until a clinical diagnosis of the underlying condition has been made. When assessing a febrile child, their temperature, heart rate, respiratory rate, and capillary refill time should be recorded. Signs of dehydration should also be looked for. Measuring temperature should be done with an electronic thermometer in the axilla if the child is under 4 weeks old or with an electronic/chemical dot thermometer in the axilla or an infrared tympanic thermometer.
The risk stratification table includes green for low risk, amber for intermediate risk, and red for high risk. The table includes categories such as color, activity, respiratory, circulation and hydration, and other symptoms. If a child is categorized as green, they can be managed at home with appropriate care advice. If they are categorized as amber, parents should be provided with a safety net or referred to a pediatric specialist for further assessment. If a child is categorized as red, they should be urgently referred to a pediatric specialist. It is important to note that oral antibiotics should not be prescribed to children with fever without an apparent source, and a chest x-ray does not need to be routinely performed if a pneumonia is suspected but the child is not going to be referred to the hospital.

A 9-month-old infant is experiencing feeding difficulties accompanied by a cough and wheeze, leading to a diagnosis of bronchiolitis. What is a triggering factor that can cause a more severe episode of bronchiolitis, rather than just an increased likelihood of developing the condition?
Your Answer: Underlying congenital heart disease
Explanation:Bronchiolitis can be more severe in individuals with congenital heart disease, particularly those with a ventricular septal defect. Fragile X is not associated with increased severity, but Down’s syndrome has been linked to worse episodes. Formula milk feeding is a risk factor for bronchiolitis, but does not affect the severity of the disease once contracted. While bronchiolitis is most common in infants aged 3-6 months, this age range is not indicative of a more severe episode. However, infants younger than 12 weeks are at higher risk. Being born at term is not a risk factor, but premature birth is associated with more severe episodes.
Bronchiolitis is a condition where the bronchioles become inflamed, and it is most commonly caused by respiratory syncytial virus (RSV). This virus is responsible for 75-80% of cases, with other causes including mycoplasma and adenoviruses. Bronchiolitis is most prevalent in infants under one year old, with 90% of cases occurring in those aged 1-9 months. The condition is more serious in premature babies, those with congenital heart disease or cystic fibrosis. Symptoms include coryzal symptoms, dry cough, increasing breathlessness, and wheezing. Hospital admission is often necessary due to feeding difficulties associated with increasing dyspnoea.
Immediate referral is recommended if the child has apnoea, looks seriously unwell, has severe respiratory distress, central cyanosis, or persistent oxygen saturation of less than 92% when breathing air. Clinicians should consider referral if the child has a respiratory rate of over 60 breaths/minute, difficulty with breastfeeding or inadequate oral fluid intake, or clinical dehydration. Immunofluorescence of nasopharyngeal secretions may show RSV, and management is largely supportive. Humidified oxygen is given via a head box if oxygen saturations are persistently low, and nasogastric feeding may be necessary if children cannot take enough fluid/feed by mouth. Suction may also be used for excessive upper airway secretions. NICE released guidelines on bronchiolitis in 2015 for more information.

A doctor is performing a routine check on a 6-month-old baby and finds that the hips are positive for Barlow and Ortolani tests. What is the most probable situation for this child?
Your Answer: Female
Explanation:Developmental dysplasia of the hip is more likely to occur in females. Positive Barlow and Ortolani tests are indicative of DDH. High birth weight, breech presentation, and oligohydramnios are risk factors for DDH, while C-section birth is not a relevant factor.
Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be bilateral in 20% of cases. Screening for DDH is recommended for infants with certain risk factors, and all infants are screened using the Barlow and Ortolani tests at the newborn and six-week baby check. Clinical examination includes testing for leg length symmetry, restricted hip abduction, and knee level when hips and knees are flexed. Ultrasound is used to confirm the diagnosis if clinically suspected, but x-ray is the first line investigation for infants over 4.5 months. Management includes the use of a Pavlik harness for children under 4-5 months and surgery for older children with unstable hips.

A mother brings her 8-week-old baby to the GP clinic for their routine 7-week check-up. The baby appears happy and responsive during the assessment. During the examination, you observe weak femoral pulses on both sides. The rest of the examination is normal.
What is the most suitable course of action to take?Your Answer: Same day discussion with paediatrics
Explanation:If a baby’s femoral pulses are absent or weak during their 6-8 week check, it is important to discuss this immediately with paediatrics. Any signs of a critical or major congenital heart abnormality should also be seen urgently by a specialist. Advising the mother that these findings are normal would be inappropriate, as they are abnormal. While safety netting is important, the child should still be seen urgently by the appropriate specialist. Taking the child to the emergency department is not the best option, as they may not be equipped to deal with this issue and will likely refer to the paediatrics team themselves. Referring routinely to paediatrics or making an appointment in 2 weeks would waste valuable time in a potentially unwell child who needs urgent referral.
Congenital heart disease can be categorized into two types: acyanotic and cyanotic. Acyanotic heart diseases are more common and include ventricular septal defects (VSD), atrial septal defect (ASD), patent ductus arteriosus (PDA), coarctation of the aorta, and aortic valve stenosis. VSD is the most common acyanotic heart disease, accounting for 30% of cases. ASDs are less common than VSDs, but they are more frequently diagnosed in adult patients as they tend to present later. On the other hand, cyanotic heart diseases are less common and include tetralogy of Fallot, transposition of the great arteries (TGA), and tricuspid atresia. Fallot’s is more common than TGA, but TGA is the more common lesion at birth as patients with Fallot’s generally present at around 1-2 months.

A 5-year-old girl is brought to the emergency department with a rash. Her parents deny any trauma and have no history with social services. She recently had a cold which resolved on its own.
The child has no medical history and was born at term through vaginal delivery. She has met all developmental milestones and is up-to-date with her vaccinations.
During examination, a petechial rash is observed on the child's legs. She appears healthy without other signs of bleeding.
Her blood tests show:
Hb 140 g/L Female: (120-160)
Platelets 25 * 109/L (150 - 400)
WBC 8.0 * 109/L (4.0 - 11.0)
What is the recommended course of action?Your Answer: None
Explanation:It is important to advise patients to avoid any trauma as it can impact the resolution of ITP, whether or not treatment is administered. Administering oral corticosteroids is not recommended as it is not necessary for a child who is not actively bleeding and the platelet count will typically recover on its own. Similarly, IV corticosteroids should not be used as they pose unnecessary risks for a child who will likely recover without the need for non-specific immunosuppressants. IV immunoglobulin is also not a suitable option as the child is not exhibiting any signs of active or previous bleeding and their platelet count is sufficient.
Understanding Immune Thrombocytopenia (ITP) in Children
Immune thrombocytopenic purpura (ITP) is a condition where the immune system attacks the platelets, leading to a decrease in their count. This condition is more common in children and is usually acute, often following an infection or vaccination. The antibodies produced by the immune system target the glycoprotein IIb/IIIa or Ib-V-IX complex, causing a type II hypersensitivity reaction.
The symptoms of ITP in children include bruising, a petechial or purpuric rash, and less commonly, bleeding from the nose or gums. A full blood count is usually sufficient to diagnose ITP, and a bone marrow examination is only necessary if there are atypical features.
In most cases, ITP resolves on its own within six months, without any treatment. However, if the platelet count is very low or there is significant bleeding, treatment options such as oral or IV corticosteroids, IV immunoglobulins, or platelet transfusions may be necessary. It is also advisable to avoid activities that may result in trauma, such as team sports. Understanding ITP in children is crucial for prompt diagnosis and management of this condition.

A 5-day-old infant presents with feeding difficulties for the past day. The baby was born at 38 weeks, induced 48 hours after pre-labor spontaneous rupture of membranes. Following observation, there were no concerns and the baby was discharged. The infant is breastfed every 1-2 hours, but over the past 24 hours, has been less interested in feeding, occurring every 3-4 hours, sometimes being woken to feed. The baby appears uncomfortable during feeding and frequently pulls away. The mother also reports an unusual grunting sound after the baby exhales. Based on this information, what is the most likely diagnosis?
Your Answer: Neonatal sepsis
Explanation:Neonatal Sepsis: Causes, Risk Factors, and Management
Neonatal sepsis is a serious bacterial or viral infection in the blood that affects babies within the first 28 days of life. It is categorized into early-onset (EOS) and late-onset (LOS) sepsis, with each category having distinct causes and common presentations. The most common causes of neonatal sepsis are group B streptococcus (GBS) and Escherichia coli, accounting for approximately two-thirds of cases. Premature and low birth weight babies are at higher risk, as well as those born to mothers with GBS colonization or infection during pregnancy. Symptoms can vary from subtle signs of illness to clear septic shock, and diagnosis is usually established through blood culture. Treatment involves early identification and use of intravenous antibiotics, with duration depending on ongoing investigations and clinical picture. Other important management factors include maintaining adequate oxygenation and fluid and electrolyte status.

A 7-year-old boy comes to the doctor's office with his mother, reporting pain in his left hip. The mother mentions that he had a recent bout of the flu. Upon examination, the boy appears alert with a heart rate of 80 bpm, respiratory rate of 20 breaths/min, temperature of 38.5ºC, blood pressure of 120/80 mmHg, and oxygen saturations of 98% on room air. What is the best course of action for management?
Your Answer: Refer for same-day assessment
Explanation:If a child is experiencing hip pain or a limp and also has a fever, it is crucial to refer them for immediate assessment, even if the suspected diagnosis is transient synovitis.
Transient synovitis is often the cause of hip pain in children following a previous illness, such as the flu. However, discharging the patient with oral antibiotics is not recommended as this condition is typically managed conservatively. Antibiotics may only be necessary if there are signs of a septic joint.
Similarly, discharging the patient with pain relief alone is not appropriate. Although a septic joint is unlikely, it cannot be ruled out without a formal assessment by orthopaedics.
Reassuring the patient and discharging them without assessment is also not an option. Given the child’s current fever and recent illness history, it is essential to conduct a thorough evaluation before considering discharge.
It is critical to refer a child with hip pain and a fever for same-day assessment to rule out the possibility of a septic joint. However, routine referral to orthopaedics is not necessary as this may cause unnecessary delays in urgent assessment.
Transient synovitis, also known as irritable hip, is a common cause of hip pain in children aged 3-8 years. It typically occurs following a recent viral infection and presents with symptoms such as groin or hip pain, limping or refusal to weight bear, and occasionally a low-grade fever. However, a high fever may indicate other serious conditions such as septic arthritis, which requires urgent specialist assessment. To exclude such diagnoses, NICE Clinical Knowledge Summaries recommend monitoring children in primary care with a presumptive diagnosis of transient synovitis, provided they are aged 3-9 years, well, afebrile, mobile but limping, and have had symptoms for less than 72 hours. Treatment for transient synovitis involves rest and analgesia, as the condition is self-limiting.

You are consulting with a family whose daughter has been referred due to suspected learning difficulties. Whilst talking to her parents, you notice that she has a friendly and sociable personality. You begin to wonder if she might have William's syndrome.
What physical characteristic would be the strongest indicator of this diagnosis?Your Answer: Elfin facies
Explanation:William’s syndrome is linked to unique physical characteristics such as elfin facies, a broad forehead, strabismus, and short stature. It is important to note that Klinefelter’s syndrome is characterized by a tall and slender stature. Edward’s syndrome is associated with rocker-bottom feet, while foetal alcohol syndrome is linked to a flattened philtrum. Turner’s syndrome and Noonan’s syndrome are associated with webbing of the neck. Individuals with William’s syndrome often have an elongated, not flat philtrum.
Understanding William’s Syndrome
William’s syndrome is a genetic disorder that affects neurodevelopment and is caused by a microdeletion on chromosome 7. The condition is characterized by a range of physical and cognitive features, including elfin-like facies, short stature, and learning difficulties. Individuals with William’s syndrome also tend to have a very friendly and social demeanor, which is a hallmark of the condition. Other common symptoms include transient neonatal hypercalcaemia and supravalvular aortic stenosis.
Diagnosis of William’s syndrome is typically made through FISH studies, which can detect the microdeletion on chromosome 7. While there is no cure for the condition, early intervention and support can help individuals with William’s syndrome to manage their symptoms and lead fulfilling lives. With a better understanding of this disorder, we can work towards improving the lives of those affected by it.

A newborn is admitted to the paediatric cardiology intensive care unit with congenital transposition of the great arteries (TGA) identified on pre-natal scans. The baby was delivered spontaneously at 38 weeks. What is the most crucial medication to administer until the neonate can undergo surgery in a few days?
Your Answer: Alprostadil
Explanation:To maintain a patent ductus arteriosus in cyanotic congenital heart diseases, prostaglandin E1 is recommended. This is particularly important in cases of transposition of the great arteries (TGA), where alprostadil is given to ensure some flow of oxygenated blood to the body. Neonatal apnoea is managed with caffeine, but it is not the primary medication used in TGA. Corticosteroids are administered to pregnant women at risk of premature birth to stimulate surfactant production in the neonatal lungs. NSAIDs such as ibuprofen and indomethacin can be used to close a persistent or symptomatic patent ductus arteriosus in babies.
Cyanosis, a bluish discoloration of the skin, is a common occurrence in newborns. Peripheral cyanosis, which affects the hands and feet, is often seen in the first 24 hours of life and can be caused by crying or illness. Central cyanosis, on the other hand, is a more serious condition that occurs when the concentration of reduced hemoglobin in the blood exceeds 5g/dl. To differentiate between cardiac and non-cardiac causes of central cyanosis, doctors may use the nitrogen washout test, which involves giving the infant 100% oxygen for ten minutes and then measuring arterial blood gases. A pO2 of less than 15 kPa indicates cyanotic congenital heart disease, which can be caused by conditions such as tetralogy of Fallot, transposition of the great arteries, and tricuspid atresia.
If cyanotic congenital heart disease is suspected, initial management involves supportive care and the use of prostaglandin E1, such as alprostadil, to maintain a patent ductus arteriosus in ductal-dependent congenital heart defects. This can serve as a temporary measure until a definitive diagnosis is made and surgical correction is performed.
Acrocyanosis, a type of peripheral cyanosis, is a benign condition that is often seen in healthy newborns. It is characterized by bluish discoloration around the mouth and extremities, such as the hands and feet, and is caused by vasomotor changes that result in peripheral vasoconstriction and increased tissue oxygen extraction. Unlike other causes of peripheral cyanosis that may indicate significant pathology, such as septic shock, acrocyanosis occurs immediately after birth in healthy infants and typically resolves within 24 to 48 hours.

A 4-year-old girl, Lily, is taken to the pediatrician by her father. He is concerned about an umbilical hernia that Lily has had since birth. He was told that it would likely go away on its own, but it has not yet resolved. The pediatrician conducts an examination and finds a 1.5 cm umbilical hernia that is easily reducible. What is the most suitable course of action for managing this, according to the guidelines?
Your Answer: Delaying referral for elective outpatient surgical repair until 5 years of age, if still unresolved
Explanation:According to medical guidelines, umbilical hernias in children usually close on their own by the age of 4-5. However, if the hernia persists beyond this age or is large and causing symptoms, surgical repair is recommended. In the case of a small hernia in a 3-year-old child, observation is appropriate until the age of 5. If the hernia becomes incarcerated, it should be manually reduced and surgically repaired within 24 hours. The use of compression therapy after surgery is not recommended. Waiting for the hernia to self-resolve after the age of 5 is not advised as it is unlikely to happen and could lead to incarceration. These recommendations are based on BMJ Best Practice guidelines.
Umbilical Hernia in Children: Causes and Treatment
Umbilical hernias are a common occurrence in children and are often detected during the newborn examination. This condition is characterized by a bulge or protrusion near the belly button, caused by a weakness in the abdominal muscles. While umbilical hernias can occur in any child, they are more common in Afro-Caribbean infants and those with Down’s syndrome or mucopolysaccharide storage diseases.
Fortunately, in most cases, umbilical hernias in children do not require treatment and will resolve on their own by the age of three. However, if the hernia persists beyond this age or becomes painful, surgery may be necessary to repair the abdominal wall. It is important to monitor the hernia and seek medical attention if there are any changes in size or symptoms.
In summary, umbilical hernias are a common condition in children that typically resolve on their own without treatment. However, certain factors such as ethnicity and underlying medical conditions may increase the likelihood of developing an umbilical hernia. Parents should be aware of the signs and symptoms of umbilical hernias and seek medical attention if necessary.

A 2-month-old infant is scheduled for a hearing screening test. She was born at 38 weeks without any pregnancy complications and delivered vaginally. Which hearing test would be most suitable for this child?
Your Answer: Automated otoacoustic emissions
Explanation:The otoacoustic emission test is specifically designed to screen newborns for hearing issues. Different hearing tests are available for different age groups, but in the UK, newborns are typically screened using the automated otoacoustic emissions test or the evoked otoacoustic emissions test. If any abnormalities are detected, the automated auditory brainstem response test is used as a follow-up. The other hearing tests mentioned are more appropriate for older children. This information is provided by the NHS in the UK.
Hearing Tests for Children
Hearing tests are important for children to ensure that they are developing normally. There are several tests that may be performed on children of different ages. For newborns, an otoacoustic emission test is typically done as part of the Newborn Hearing Screening Programme. This test involves playing a computer-generated click through a small earpiece and checking for the presence of a soft echo, which indicates a healthy cochlea. If the results of this test are abnormal, an Auditory Brainstem Response test may be done.
For infants between 6-9 months, a Distraction test may be performed by a health visitor with the help of two trained staff members. For children between 18 months to 2.5 years, a Recognition of familiar objects test may be used, which involves using familiar objects like a teddy or cup and asking the child simple questions like where is the teddy? For children over 2.5 years, Performance testing and Speech discrimination tests may be used, such as the Kendall Toy test or McCormick Toy Test. Pure tone audiometry is typically done at school entry in most areas of the UK for children over 3 years old.
In addition to these tests, there is also a questionnaire for parents in the Personal Child Health Records called Can your baby hear you? It is important for parents to be aware of these tests and to have their child’s hearing checked regularly to ensure proper development.

A 6-year-old girl is brought to the paediatric clinic by her father with a sore throat that worsens with swallowing, headaches, and malaise. He reports no coughing.
Upon examination, her temperature is 38.5ºC, her heart rate is 100 bpm, and her tonsils are symmetrically enlarged and red, with white patches present. There is tender anterior cervical lymphadenopathy. The doctor's overall impression is that of an ill child.
The patient has no medical history but is allergic to penicillin. What is the most appropriate immediate step in her management?Your Answer: Immediate hospital admission
Explanation:Immediate hospital admission is necessary for a child with fevers who appears unwell to a paediatric healthcare professional, as this is considered a red flag indicating severe illness. In this case, the child has a Centor score of 4 and presents with tonsillitis symptoms, including tonsillar exudate, tender cervical lymphadenopathy, fever, and no cough. While antibiotic treatment may be warranted, the priority is to admit the child for assessment and management of their condition. Delayed antibiotic prescription or prescribing a specific antibiotic, such as clarithromycin or phenoxymethylpenicillin, would not be appropriate in this situation.
The NICE Feverish illness in children guidelines were introduced in 2007 and updated in 2013. These guidelines use a ‘traffic light’ system to assess the risk of children under 5 years old presenting with a fever. It is important to note that these guidelines only apply until a clinical diagnosis of the underlying condition has been made. When assessing a febrile child, their temperature, heart rate, respiratory rate, and capillary refill time should be recorded. Signs of dehydration should also be looked for. Measuring temperature should be done with an electronic thermometer in the axilla if the child is under 4 weeks old or with an electronic/chemical dot thermometer in the axilla or an infrared tympanic thermometer.
The risk stratification table includes green for low risk, amber for intermediate risk, and red for high risk. The table includes categories such as color, activity, respiratory, circulation and hydration, and other symptoms. If a child is categorized as green, they can be managed at home with appropriate care advice. If they are categorized as amber, parents should be provided with a safety net or referred to a pediatric specialist for further assessment. If a child is categorized as red, they should be urgently referred to a pediatric specialist. It is important to note that oral antibiotics should not be prescribed to children with fever without an apparent source, and a chest x-ray does not need to be routinely performed if a pneumonia is suspected but the child is not going to be referred to the hospital.

A 6-year-old girl comes to the clinic with a widespread rash on her cheeks, neck, and trunk. The rash does not appear on her palms. The texture of the rash is rough and it appears red. The child's mother reports that she has been experiencing a sore throat for the past 48 hours. The child has no known allergies. What is the recommended treatment for this condition?
Your Answer: Oral penicillin V for 10 days and he is safe to return to school after 24 hours
Explanation:The recommended treatment for scarlet fever in patients who do not require hospitalization and have no penicillin allergy is a 10-day course of oral penicillin V. Patients should also be advised not to return to school until at least 24 hours after starting antibiotics. Scarlet fever is characterized by a red, rough, sandpaper-textured rash with deep red linear appearance in skin folds and sparing of the palms and soles. Calamine lotion and school exclusion until scabs have crusted over is not the correct treatment for scarlet fever, but rather for chicken pox. High-dose aspirin is not the correct treatment for scarlet fever, but rather for Kawasaki disease. No medication is not the correct treatment for scarlet fever, as it is a bacterial infection that requires antibiotic therapy. Oral acyclovir for 10 days is not the correct treatment for scarlet fever, but rather for shingles caused by herpes varicella zoster virus.
Scarlet fever is a condition caused by erythrogenic toxins produced by Group A haemolytic streptococci, usually Streptococcus pyogenes. It is more prevalent in children aged 2-6 years, with the highest incidence at 4 years. The disease spreads through respiratory droplets or direct contact with nose and throat discharges, especially during sneezing and coughing. The incubation period is 2-4 days, and symptoms include fever, malaise, headache, nausea/vomiting, sore throat, ‘strawberry’ tongue, and a rash that appears first on the torso and spares the palms and soles. The rash has a rough ‘sandpaper’ texture and desquamation occurs later in the course of the illness, particularly around the fingers and toes.
To diagnose scarlet fever, a throat swab is usually taken, but antibiotic treatment should be initiated immediately, rather than waiting for the results. Management involves administering oral penicillin V for ten days, while patients with a penicillin allergy should be given azithromycin. Children can return to school 24 hours after commencing antibiotics, and scarlet fever is a notifiable disease. Although usually a mild illness, scarlet fever may be complicated by otitis media, rheumatic fever, acute glomerulonephritis, or rare invasive complications such as bacteraemia, meningitis, or necrotizing fasciitis, which may present acutely with life-threatening illness.

You are evaluating the growth of a 6-week-old infant. Her length is at the 35th percentile, weight at the 42nd percentile, and head circumference at the 4th percentile. What is the probable reason for her microcephaly?
Your Answer: Foetal alcohol syndrome
Explanation:Microcephaly is often linked to foetal alcohol syndrome, which also presents with other physical characteristics such as a smooth philtrum, hypoplastic upper lip, and epicanthic folds. Conditions like Thalassaemia, Turner’s syndrome, and cerebral palsy do not typically impact head size, while Achondroplasia is associated with macrocephaly and frontal bossing, not microcephaly. Recognizing the distinct physical features of congenital conditions is crucial for both exams and accurate diagnosis.
Understanding Fetal Alcohol Syndrome
Fetal alcohol syndrome is a condition that occurs when a pregnant woman consumes alcohol, which can lead to various physical and mental abnormalities in the developing fetus. At birth, the baby may exhibit symptoms of alcohol withdrawal, such as irritability, hypotonia, and tremors.
The features of fetal alcohol syndrome include a short palpebral fissure, a thin vermillion border or hypoplastic upper lip, a smooth or absent philtrum, learning difficulties, microcephaly, growth retardation, epicanthic folds, and cardiac malformations. These physical characteristics can vary in severity and may affect the child’s overall health and development.
It is important for pregnant women to avoid alcohol consumption to prevent fetal alcohol syndrome and other potential complications. Early diagnosis and intervention can also help improve outcomes for children with fetal alcohol syndrome. By understanding the risks and consequences of alcohol use during pregnancy, we can work towards promoting healthier pregnancies and better outcomes for children.

A 6-month-old infant is scheduled for routine immunisations. All recommended immunisations have been administered so far. What vaccinations should be given at this point?
Your Answer: Hib/Men C + MMR + PCV + Men B
Explanation:The UK immunisation schedule recommends certain vaccines at different ages. At birth, the BCG vaccine is given if the baby is at risk of tuberculosis. At 2, 3, and 4 months, the ‘6-1 vaccine’ (diphtheria, tetanus, whooping cough, polio, Hib and hepatitis B) and oral rotavirus vaccine are given, along with Men B and PCV at certain intervals. At 12-13 months, the Hib/Men C, MMR, and PCV vaccines are given, along with Men B. At 3-4 years, the ‘4-in-1 preschool booster’ (diphtheria, tetanus, whooping cough and polio) and MMR vaccines are given. At 12-13 years, the HPV vaccination is given, and at 13-18 years, the ‘3-in-1 teenage booster’ (tetanus, diphtheria and polio) and Men ACWY vaccines are given. Additionally, the flu vaccine is recommended annually for children aged 2-8 years.
It is important to note that the meningitis ACWY vaccine has replaced meningitis C for 13-18 year-olds due to an increased incidence of meningitis W disease in recent years. The ACWY vaccine will also be offered to new students (up to the age of 25 years) at university. GP practices will automatically send letters inviting 17-and 18-year-olds in school year 13 to have the Men ACWY vaccine. Students going to university or college for the first time as freshers, including overseas and mature students up to the age of 25, should contact their GP to have the Men ACWY vaccine, ideally before the start of the academic year.
It is worth noting that the Men C vaccine used to be given at 3 months but has now been discontinued. This is because the success of the Men C vaccination programme means there are almost no cases of Men C disease in babies or young children in the UK any longer. All children will continue to be offered the Hib/Men C vaccine at one year of age, and the Men ACWY vaccine at 14 years of age to provide protection across all age groups.

The pediatrician is asked to review a 4 hour old term baby by the nurse. The mother had no antenatal concerns and was not on any medication during pregnancy. The baby has not yet latched to the breast and appears lethargic. A heel prick blood sugar test was done and the result was as follows:
Glucose 2.5 mmol/L (4.0-5.9)
Upon examination, the baby was easily rousable and had a good suck. He had normal tone and cardiovascular examination was unremarkable. However, he had not passed urine or opened his bowels yet.
What should be the first step in the pediatrician's management plan for this baby?Your Answer: Ask the breastfeeding support team to come and support mum and baby with attempting a further feed now
Explanation:It is common for newborns to experience transient hypoglycemia in the first few hours after birth. If a mother wishes to breastfeed, she should be provided with support and guidance on proper latching techniques and encouraged to engage in skin-to-skin contact with her baby. If the baby is having difficulty feeding, the mother can be taught how to hand express and provide colostrum through alternative methods. Blood glucose levels should be monitored before and after each feeding, without more than three hours between feeds. If the baby is asymptomatic, buccal glucose can be administered in conjunction with a feeding plan. However, if the baby has not yet had a feed and is mildly hypoglycemic, action should be taken and blood sugar levels should be checked again prior to the next feeding. It is important to provide mothers with information and support to encourage breastfeeding, rather than immediately suggesting formula feeding for a well, asymptomatic term baby. These guidelines are based on the BAPM Framework for Practice’s Identification and Management of Neonatal Hypoglycemia in the Full Term Infant (2017).
Neonatal Hypoglycaemia: Causes, Symptoms, and Management
Neonatal hypoglycaemia is a common condition in newborn babies, especially in the first 24 hours of life. While there is no agreed definition, a blood glucose level of less than 2.6 mmol/L is often used as a guideline. Transient hypoglycaemia is normal and usually resolves on its own, but persistent or severe hypoglycaemia may be caused by various factors such as preterm birth, maternal diabetes mellitus, IUGR, hypothermia, neonatal sepsis, inborn errors of metabolism, nesidioblastosis, or Beckwith-Wiedemann syndrome.
Symptoms of neonatal hypoglycaemia can be autonomic, such as jitteriness, irritability, tachypnoea, and pallor, or neuroglycopenic, such as poor feeding/sucking, weak cry, drowsiness, hypotonia, and seizures. Other features may include apnoea and hypothermia. Management of neonatal hypoglycaemia depends on the severity of the condition and whether the newborn is symptomatic or not. Asymptomatic babies can be encouraged to feed normally and have their blood glucose monitored, while symptomatic or severely hypoglycaemic babies may need to be admitted to the neonatal unit and receive intravenous infusion of 10% dextrose.

A 12-year-old boy is brought into the Emergency Department by his mother. He is known to have haemophilia B and has fallen while playing basketball. His ankle is very swollen and bruised.
Which of the following would be the best treatment option for this patient?Your Answer: Recombinant factor IX
Explanation:Treatment Options for Haemophilia B: Recombinant Factor IX and Cryoprecipitate
Haemophilia B, also known as Christmas disease, is a rare genetic disorder caused by a deficiency in factor IX. While it shares similar inheritance patterns and clinical features with haemophilia A, its incidence is much lower. Treatment for haemophilia B involves factor IX concentrates, with recombinant factor IX being the most commonly used. Prophylactic doses may be given twice a week for patients with severe disease or a history of significant bleeding, but there is a risk of developing inhibitors against the factor.
Cryoprecipitate, on the other hand, does not contain factor IX but rather fibrinogen, von Willebrand’s factor, and factors VIII and XIII. It may be used in certain situations, but it is not a primary treatment for haemophilia B.
It is important to note that recombinant factor VIII is not indicated for haemophilia B, as it is specific to haemophilia A. Similarly, factor XI is not a treatment option for haemophilia B.
While factor IX is a vitamin K-dependent clotting factor, the deficiency in haemophilia B is not caused by a lack of vitamin K. Understanding the appropriate treatment options for haemophilia B is crucial for managing this rare disorder.

Sophie is a 6-year-old girl who requires a blood transfusion after a serious accident. Her condition is critical and she needs urgent resuscitation. Sophie has suffered significant blood loss and will not survive without a transfusion. However, her parents are Jehovah's Witnesses and are present, but they refuse to provide consent for the blood transfusion. What is the most appropriate course of action?
Your Answer: Give the blood transfusion because it is a life threatening situation and it is in James' best interest
Explanation:According to the GMC guidelines, if a child lacks the capacity to make a decision and both parents refuse treatment due to their religious or moral beliefs, healthcare professionals must discuss their concerns and explore treatment options that align with their beliefs. The child should also be involved in a manner that is appropriate for their age and maturity. If an agreement cannot be reached after discussing all options, and treatment is necessary to preserve life or prevent serious health deterioration, healthcare professionals should seek advice on approaching the court. In emergency situations, treatment that is immediately necessary to save a life or prevent health deterioration can be provided without consent or, in rare cases, against the wishes of a person with parental responsibility.
Understanding Consent in Children
The issue of consent in children can be complex and confusing. However, there are some general guidelines to follow. If a patient is under 16 years old, they may be able to consent to treatment if they are deemed competent. This is determined by the Fraser guidelines, which were previously known as Gillick competence. However, even if a child is competent, they cannot refuse treatment that is deemed to be in their best interest.
For patients between the ages of 16 and 18, it is generally assumed that they are competent to give consent to treatment. Patients who are 18 years or older can consent to or refuse treatment.
When it comes to providing contraceptives to patients under 16 years old, the Fraser Guidelines outline specific requirements that must be met. These include ensuring that the young person understands the advice given by the healthcare professional, cannot be persuaded to inform their parents, is likely to engage in sexual activity with or without treatment, and will suffer physical or mental health consequences without treatment. Ultimately, the young person’s best interests must be taken into account when deciding whether to provide contraceptive advice or treatment, with or without parental consent.
In summary, understanding consent in children requires careful consideration of age, competence, and best interests. The Fraser Guidelines provide a useful framework for healthcare professionals to follow when providing treatment and advice to young patients.

A 10-year-old boy with severe haemophilia A is brought to the Emergency Department by his mother due to a nosebleed that has been ongoing for over 30 minutes. He is currently receiving regular injections to manage his condition but is aware that further treatment may be necessary in the event of a significant bleed. What is the most appropriate course of action for managing this patient?
Your Answer: Recombinant factor VIII
Explanation:Treatment Options for Haemophilia A: Recombinant Factor VIII and Desmopressin
Haemophilia A is a genetic condition that results in a deficiency of clotting factor VIII. The severity of the condition varies depending on the level of factor VIII present. Patients with severe haemophilia A or a history of significant bleeds may receive prophylactic recombinant factor VIII to prevent recurrent bleeding and joint damage. In cases of acute bleeding, recombinant factor VIII can be used to stop the bleed. Desmopressin is an option for mild to moderate haemophilia A, but is not effective for severe cases or haemophilia B. Local measures can also be used to minimize bleeding, but the best option for a child with severe haemophilia A experiencing significant epistaxis is to treat with recombinant factor VIII.

A 10-year-old girl presents to the Emergency department with complaints of hip and knee pain following a minor fall from her bike. Upon examination, her knee appears normal but there is limited range of motion at the hip joint. What is the probable diagnosis?
Your Answer: Slipped upper femoral epiphysis
Explanation:Slipped Upper Femoral Epiphysis: Symptoms and Risk Factors
Slipped upper femoral epiphysis is a condition that commonly affects obese adolescent boys with a positive family history. It is characterized by the displacement of the femoral head from the femoral neck, which can lead to a range of symptoms.
The most common symptoms of slipped upper femoral epiphysis include an externally rotated hip and antalgic gait, decreased internal rotation, thigh atrophy (depending on the chronicity of symptoms), and hip, thigh, and knee pain.
It is important to note that 25% of cases are bilateral, meaning that both hips may be affected. This condition can be particularly debilitating for young people, as it can limit their mobility and cause significant discomfort.
Overall, it is important for healthcare professionals to be aware of the risk factors and symptoms of slipped upper femoral epiphysis, as early diagnosis and treatment can help to prevent further complications and improve outcomes for patients.

A 6-year-old girl has been referred to the enuresis clinic by her pediatrician due to ongoing bedwetting. Her mother has expressed concern as the girl has never had a dry night. The pediatrician has provided advice on diet, fluid intake, and toileting habits, but the bedwetting persists despite the use of a reward system. The mother has contacted the enuresis clinic for further intervention. What is the likely intervention that will be provided?
Your Answer: Enuresis alarm
Explanation:When a child experiences nocturnal enuresis, an enuresis alarm is typically the first option if general advice has not been effective. According to NICE guidelines, this is the primary approach. It may be worthwhile to consider a more appealing reward system to motivate the child, as they may not be incentivized if the prize is not deemed valuable. However, it is assumed that the mother can adequately motivate their child, so this may not be the chosen route for the clinic. If the initial intervention is unsuccessful, it is unlikely that repeating it will yield different results. If the enuresis alarm is not effective, pharmacological interventions such as desmopressin, oxybutynin, and unlicensed tolterodine may be considered, with desmopressin being the usual choice.
Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.
When managing bedwetting, it’s important to look for any underlying causes or triggers, such as constipation, diabetes mellitus, or recent onset UTIs. General advice includes monitoring fluid intake and encouraging regular toileting patterns, such as emptying the bladder before sleep. Reward systems, like star charts, can also be helpful, but should be given for agreed behavior rather than dry nights.
The first-line treatment for bedwetting is an enuresis alarm, which has a high success rate. These alarms have sensor pads that detect wetness and wake the child up to use the toilet. If short-term control is needed, such as for sleepovers, or if the alarm is ineffective or not acceptable to the family, desmopressin may be prescribed. Overall, managing bedwetting involves identifying any underlying causes and implementing strategies to promote continence.

A 14-year-old girl from Germany comes to the clinic complaining of chronic diarrhoea that has been ongoing for the past 10 months. She also reports having foul smelling stools. Her medical history includes recurrent chest infections since childhood and a diagnosis of diabetes mellitus.
What is the probable diagnosis?Your Answer: Cystic fibrosis
Explanation:Regional research programs and voluntary early-detection programs test a significant number of neonates for cystic fibrosis. While coeliac disease and type 1 diabetes mellitus are often associated due to their auto-immune nature, the recurring chest infections are not indicative of coeliac disease.
Cystic Fibrosis: Symptoms and Characteristics
Cystic fibrosis is a genetic disorder that affects various organs in the body, particularly the lungs and digestive system. The symptoms of cystic fibrosis can vary from person to person, but there are some common features that are often present. In the neonatal period, around 20% of infants with cystic fibrosis may experience meconium ileus, which is a blockage in the intestine caused by thick, sticky mucous. Prolonged jaundice may also occur, but less commonly. Recurrent chest infections are a common symptom, affecting around 40% of patients. Malabsorption is another common feature, with around 30% of patients experiencing steatorrhoea (excessive fat in the stool) and failure to thrive. Liver disease may also occur in around 10% of patients.
It is important to note that while many patients are diagnosed with cystic fibrosis during newborn screening or early childhood, around 5% of patients are not diagnosed until after the age of 18. Other features of cystic fibrosis may include short stature, diabetes mellitus, delayed puberty, rectal prolapse (due to bulky stools), nasal polyps, male infertility, and female subfertility. Overall, the symptoms and characteristics of cystic fibrosis can vary widely, but early diagnosis and treatment can help manage the condition and improve quality of life.

You are working in the Neonatal Intensive Care Unit and currently assessing a 3-day-old boy with respiratory distress due to meconium aspiration. The mother is visibly upset and asks if there was anything she could have done to prevent this.
After reviewing the medical history, you find that the baby was conceived through in vitro fertilization, there were no complications during the pregnancy, but he was delivered via C-section at 41 weeks with a birth weight of 2.6kg.
What is the most significant risk factor for meconium aspiration in this particular case?Your Answer: Post-term delivery
Explanation:Post-term delivery is a major risk factor for meconium aspiration, which is why women are induced following term. Placental insufficiency, not low birth weight, is a consequence of meconium aspiration. The sex of the child and assisted reproduction are not considered independent risk factors. While meconium aspiration may cause distress during labor and potentially result in a Caesarean section, it is not a risk factor on its own.
Understanding Meconium Aspiration Syndrome
Meconium aspiration syndrome is a condition that affects newborns and causes respiratory distress due to the presence of meconium in the trachea. This condition typically occurs in the immediate neonatal period and is more common in post-term deliveries, with rates of up to 44% reported in babies born after 42 weeks. The severity of the respiratory distress can vary, but it can be quite severe in some cases.
There are several risk factors associated with meconium aspiration syndrome, including a history of maternal hypertension, pre-eclampsia, chorioamnionitis, smoking, or substance abuse. These risk factors can increase the likelihood of a baby developing this condition. It is important for healthcare providers to be aware of these risk factors and to monitor newborns closely for signs of respiratory distress.
Overall, meconium aspiration syndrome is a serious condition that requires prompt medical attention. With proper management and treatment, however, most babies are able to recover fully and go on to lead healthy lives. By understanding the risk factors and symptoms associated with this condition, healthcare providers can help ensure that newborns receive the care they need to thrive.

You are scheduled to see a 12-year-old girl in your clinic. The booking notes indicate that her mother is worried about her daughter's growth compared to her peers. Before the appointment, you quickly review the patient's medical records. The patient's past medical history includes asthma, attention deficit hyperactivity disorder, and being born prematurely at 35 weeks. The patient is taking methylphenidate, a beclomethasone inhaler during the winter months, and a salbutamol inhaler. The patient's family history shows that both parents are of average height, and a blood test conducted a year ago revealed borderline low ferritin levels. What is the most relevant information for this presentation?
Your Answer: Methylphenidate
Explanation:The most important information in the patient’s records is that he is taking methylphenidate for attention deficit hyperactivity disorder, which can lead to stunted growth. Therefore, his height and weight should be monitored every six months. Although corticosteroid inhalers like beclomethasone can also cause growth reduction in children who use them regularly, this is less likely to be relevant in this case since the patient only uses it intermittently. The patient’s blood test results indicating borderline low ferritin levels may suggest a poor diet, which could potentially affect growth, but this was a while ago and limits any conclusions that can be drawn. While familial height can be helpful, it is not as significant as the patient’s medication history, especially since both parents have average heights.
In March 2018, NICE released new guidelines for identifying and managing Attention Deficit Hyperactivity Disorder (ADHD). This condition can have a significant impact on a child’s life and can continue into adulthood, making accurate diagnosis and treatment crucial. According to DSM-V, ADHD is characterized by persistent features of inattention and/or hyperactivity/impulsivity, with an element of developmental delay. Children up to the age of 16 must exhibit six of these features, while those aged 17 or over must exhibit five. ADHD has a UK prevalence of 2.4%, with a higher incidence in boys than girls, and there may be a genetic component.
NICE recommends a holistic approach to treating ADHD that is not solely reliant on medication. After presentation, a ten-week observation period should be implemented to determine if symptoms change or resolve. If symptoms persist, referral to secondary care is necessary, typically to a paediatrician with a special interest in behavioural disorders or to the local Child and Adolescent Mental Health Service (CAMHS). A tailored plan of action should be developed, taking into account the patient’s needs and wants, as well as how their condition affects their lives.
Drug therapy should be considered a last resort and is only available to those aged 5 years or older. Parents of children with mild/moderate symptoms can benefit from attending education and training programmes. For those who do not respond or have severe symptoms, pharmacotherapy may be considered. Methylphenidate is the first-line treatment for children and should be given on a six-week trial basis. It is a CNS stimulant that primarily acts as a dopamine/norepinephrine reuptake inhibitor. Side effects include abdominal pain, nausea, and dyspepsia. Weight and height should be monitored every six months in children. If there is an inadequate response, lisdexamfetamine should be considered, followed by dexamfetamine if necessary. In adults, methylphenidate or lisdexamfetamine are the first-line options, with switching between drugs if no benefit is seen after a trial of the other. All of these drugs are potentially cardiotoxic, so a baseline ECG should be performed before starting treatment, and referral to a cardiologist should be made if there is any significant past medical history or family history, or any doubt or ambiguity.
As with most psychiatric conditions, a thorough history and clinical examination are essential, particularly given the overlap of ADHD with many other psychiatric and

You are observing a doctor on the neonatal ward who is asked to assess a 3-hour-old baby delivered at 40+5 weeks by ventouse. The mother is concerned about the appearance of her baby's head. Upon examination, you notice a soft, puffy swelling at the back of the head with some light bruising from the ventouse cup. The swelling seems to extend across the suture lines. However, the baby appears to be in good health otherwise, and the neonatal hearing screen conducted earlier that morning was normal. What could be the probable cause of this presentation?
Your Answer: Caput succedaneum
Explanation:Caput succedaneum is a puffy swelling that occurs over the presenting part during prolonged ventouse delivery and resolves spontaneously. It differs from bulging fontanelle, which is caused by increased intracranial pressure, and cephalohaematoma, which is a swelling caused by fluid collecting between the periosteum and skull. Hydrocephalus is a condition where there is an accumulation of cerebrospinal fluid around the brain, and subaponeurotic haemorrhage is a rare condition caused by rupturing of emissary veins.
Understanding Caput Succedaneum
Caput succedaneum is a condition that refers to the swelling of the scalp at the top of the head, usually at the vertex. This swelling is caused by the mechanical trauma that occurs during delivery, particularly in prolonged deliveries or those that involve the use of vacuum delivery. The condition is characterized by soft, puffy swelling due to localized edema that crosses suture lines.
Compared to cephalohaematoma, which is a collection of blood under the scalp, caput succedaneum is caused by edema. While cephalohaematoma is limited to a specific area and does not cross suture lines, caput succedaneum can affect a larger area and cross suture lines. Fortunately, no treatment is needed for caput succedaneum, as the swelling usually resolves on its own within a few days.

As an F1 in the emergency department, you receive a 15-year-old girl who has been brought in from her high school due to complaints of abdominal pain and nausea. Upon examination, you discover that she is septic and can only provide a brief medical history before becoming drowsy. The surgical team suspects that she may have a perforated appendicitis and requires immediate surgery. Unfortunately, the patient's parents cannot be reached with the contact numbers provided by the school, and the patient is not in a state to provide consent for the operation. What would be the most appropriate course of action in this situation?
Your Answer: Take the patient to surgery immediately
Explanation:According to GMC, it is permissible to administer emergency treatment to a child or young person without their consent in order to save their life or prevent their health from seriously deteriorating. This means that obtaining consent from their parents, seeking permission from others, or obtaining a court order is not required.
Understanding Consent in Children
The issue of consent in children can be complex and confusing. However, there are some general guidelines to follow. If a patient is under 16 years old, they may be able to consent to treatment if they are deemed competent. This is determined by the Fraser guidelines, which were previously known as Gillick competence. However, even if a child is competent, they cannot refuse treatment that is deemed to be in their best interest.
For patients between the ages of 16 and 18, it is generally assumed that they are competent to give consent to treatment. Patients who are 18 years or older can consent to or refuse treatment.
When it comes to providing contraceptives to patients under 16 years old, the Fraser Guidelines outline specific requirements that must be met. These include ensuring that the young person understands the advice given by the healthcare professional, cannot be persuaded to inform their parents, is likely to engage in sexual activity with or without treatment, and will suffer physical or mental health consequences without treatment. Ultimately, the young person’s best interests must be taken into account when deciding whether to provide contraceptive advice or treatment, with or without parental consent.
In summary, understanding consent in children requires careful consideration of age, competence, and best interests. The Fraser Guidelines provide a useful framework for healthcare professionals to follow when providing treatment and advice to young patients.

A 2-year-old girl is brought to the pediatrician by her father due to concerns about her breathing. The father reports that she has had a fever, cough, and runny nose for the past three days, and has been wheezing for the past 24 hours. On examination, the child has a temperature of 37.9ºC, a heart rate of 126/min, a respiratory rate of 42/min, and bilateral expiratory wheezing is noted. The pediatrician prescribes a salbutamol inhaler with a spacer. However, two days later, the father returns with the child, stating that the inhaler has not improved her wheezing. The child's clinical findings are similar, but her temperature is now 37.4ºC. What is the most appropriate next step in management?
Your Answer: Oral montelukast or inhaled corticosteroid
Explanation:Child has viral-induced wheeze, treat with short-acting bronchodilator. If not successful, try oral montelukast or inhaled corticosteroids.
Understanding and Managing preschool Wheeze in Children
Wheeze is a common occurrence in preschool children, with around 25% experiencing it before they reach 18 months old. Viral-induced wheeze is now one of the most frequently diagnosed conditions in paediatric wards. However, there is still ongoing debate about how to classify wheeze in this age group and the most effective management strategies.
The European Respiratory Society Task Force has proposed a classification system for preschool wheeze, dividing children into two groups: episodic viral wheeze and multiple trigger wheeze. Episodic viral wheeze occurs only during a viral upper respiratory tract infection and is symptom-free in between episodes. Multiple trigger wheeze, on the other hand, can be triggered by various factors, such as exercise, allergens, and cigarette smoke. While episodic viral wheeze is not associated with an increased risk of asthma in later life, some children with multiple trigger wheeze may develop asthma.
To manage preschool wheeze, parents who smoke should be strongly encouraged to quit. For episodic viral wheeze, treatment is symptomatic, with short-acting beta 2 agonists or anticholinergic via a spacer as the first-line treatment. If symptoms persist, a trial of intermittent leukotriene receptor antagonist (montelukast), intermittent inhaled corticosteroids, or both may be recommended. Oral prednisolone is no longer considered necessary for children who do not require hospital treatment. For multiple trigger wheeze, a trial of inhaled corticosteroids or a leukotriene receptor antagonist (montelukast) for 4-8 weeks may be recommended.
Overall, understanding the classification and management of preschool wheeze can help parents and healthcare professionals provide appropriate care for children experiencing this common condition.

A family consisting of a husband, wife, and their toddler son visit a genetic counselling session. The son has recently been diagnosed with hereditary haemochromatosis, and both parents are carriers. They are worried as they had plans to expand their family.
What is the likelihood of their next child having the same genotype?Your Answer: 25%
Explanation:Understanding Autosomal Recessive Inheritance
Autosomal recessive inheritance is a genetic pattern where a disorder is only expressed when an individual inherits two copies of a mutated gene, one from each parent. This means that only homozygotes, individuals with two copies of the mutated gene, are affected. Both males and females are equally likely to be affected, and the disorder may not manifest in every generation, as it can skip a generation.
When two heterozygote parents, carriers of the mutated gene, have children, there is a 25% chance of having an affected (homozygote) child, a 50% chance of having a carrier (heterozygote) child, and a 25% chance of having an unaffected child. On the other hand, if one parent is homozygote for the gene and the other is unaffected, all the children will be carriers.
Autosomal recessive disorders are often metabolic in nature and can be life-threatening compared to autosomal dominant conditions. Understanding the inheritance pattern of autosomal recessive disorders is crucial in genetic counseling and family planning.

You are requested to assess a 35-year-old man who has presented to the emergency department complaining of shortness of breath, fever, and unusual breathing sounds for the past twelve hours. He reports having a sore throat for the past few days, which has rapidly worsened. He has no significant medical history.
Upon examination, his vital signs are as follows: respiratory rate 30/min, pulse 120 bpm, oxygen saturation 96%, temperature 39.0ºC, blood pressure 110/60 mmHg. From the end of the bed, you can observe that he is visibly struggling to breathe, has a hoarse voice, and is drooling into a container. You can hear a high-pitched wheeze during inspiration.
What would be the most appropriate course of action at this point?Your Answer: Call the on-call anaesthetist to assess the patient for intubation
Explanation:In cases of acute epiglottitis, protecting the airway is crucial and may require endotracheal intubation. Symptoms such as high fever, sore throat, dyspnoea, change in voice, and inspiratory stridor indicate a potential airway emergency. While other treatments may be necessary, securing the airway should be the top priority, following the ABCDE management steps. IV dexamethasone can help reduce laryngeal oedema, but an anaesthetic assessment should be arranged before administering any medication. Nebulised salbutamol is ineffective in treating laryngeal narrowing caused by epiglottitis. X-rays of the neck may be used, but they can take time to organise and delay urgent airway management. Attempting to visualise the larynx without appropriate senior support and intubation capabilities is dangerous in cases of acute epiglottitis. Flexible nasendoscopy should only be performed with the presence of trained personnel who can secure the airway if necessary.
Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B. It is important to recognize and treat it promptly as it can lead to airway obstruction. Although it was once considered a disease of childhood, it is now more common in adults in the UK due to the immunization program. The incidence of epiglottitis has decreased since the introduction of the Hib vaccine. Symptoms include a rapid onset, high temperature, stridor, drooling of saliva, and a tripod position where the patient leans forward and extends their neck to breathe easier. Diagnosis is made by direct visualization, but x-rays may be done to rule out a foreign body.
Immediate senior involvement is necessary, including those who can provide emergency airway support such as anaesthetics or ENT. Endotracheal intubation may be necessary to protect the airway. It is important not to examine the throat if epiglottitis is suspected due to the risk of acute airway obstruction. The diagnosis is made by direct visualization, but only senior staff who are able to intubate if necessary should perform this. Treatment includes oxygen and intravenous antibiotics.

A 4-year-old girl is seen by the General Practitioner (GP). She has been unwell with coryzal symptoms for two days and has fever. She has been eating a little less than usual but drinking plenty of fluids and having her normal amount of wet nappies. Her mother reports that she had an episode of being unresponsive and her limbs were jerking while in the waiting room that lasted about 30 seconds. On examination, following the episode, she is alert, without signs of focal neurology. Her temperature is 38.9 °C, heart rate 120 bpm and capillary refill time < 2 seconds. She has moist mucous membranes. There is no sign of increased work of breathing. Her chest is clear. She has cervical lymphadenopathy; her throat is red, but no exudate is present on her tonsils. She has clear, thick nasal discharge, and both her tympanic membranes are inflamed, but not bulging.
Which of the following is most likely to indicate that the child can be managed safely at home?Your Answer: Examination reveals signs of pneumonia
Correct Answer:
Explanation:When to Seek Urgent Medical Attention for Febrile Convulsions in Children
Febrile convulsions are seizures that occur in response to a high body temperature in children aged between six months and three years. While most febrile convulsions are harmless and do not require urgent medical attention, there are certain red flag features that parents should be aware of. If any of the following features are present, urgent hospital admission is necessary:
– Children aged less than 18 months
– Diagnostic uncertainty
– Convulsion lasting longer than 5 minutes
– Focal features during the seizure
– Recurrence of convulsion during the same illness or in the last 24 hours
– Incomplete recovery one hour after the convulsion
– No focus of infection identified
– Examination findings suggesting a serious cause for fever such as pneumonia
– Child currently taking antibiotics, with a clear bacterial focus of infectionIt is important to note that a first febrile convulsion in a child is also an indication for urgent hospital admission. If a child less than six months or over three years experiences a seizure not associated with fever, it may be due to an underlying neurological condition and require further specialist investigation. Parents should be aware of these red flag features and seek medical attention promptly if they are present.

A 12-year-old girl comes to the emergency department with a headache. During the examination, she mentions that the lights are bothering her eyes and the doctor observes a purpuric rash on her chest. Her respiratory rate is 22/min, heart rate is 140/min, and blood pressure is 80/60 mmHg. Which of the following tests should be avoided in this patient?
Your Answer: Blood cultures
Correct Answer: Lumbar puncture
Explanation:Performing a lumbar puncture is not recommended for patients with meningococcal septicaemia, which is a contraindication. In cases of suspected meningitis and sepsis, a coagulation screen and blood glucose may be ordered in secondary care, while blood cultures and serum lactate are typically included in the sepsis 6 protocol.
Investigation and Management of Meningitis in Children
Meningitis is a serious condition that can affect children. When investigating meningitis, it is important to note any contraindications to lumbar puncture, such as signs of raised intracranial pressure, focal neurological signs, papilloedema, significant bulging of the fontanelle, disseminated intravascular coagulation, or signs of cerebral herniation. For patients with meningococcal septicaemia, a lumbar puncture is contraindicated, and blood cultures and PCR for meningococcal should be obtained instead.
The management of meningitis in children involves administering antibiotics, such as IV amoxicillin (or ampicillin) and IV cefotaxime for children under three months, and IV cefotaxime (or ceftriaxone) for children over three months. Steroids should be considered if the lumbar puncture reveals certain findings, such as purulent cerebrospinal fluid, a high white blood cell count, or bacteria on Gram stain. Fluids should be administered to treat shock, and cerebral monitoring should be conducted, including mechanical ventilation if necessary.
It is also important to notify public health authorities and administer antibiotic prophylaxis to contacts. Ciprofloxacin is now preferred over rifampicin for this purpose. Overall, prompt and appropriate management of meningitis in children is crucial for ensuring the best possible outcomes.

A 6-year-old girl is brought to the emergency department by her father. Her temperature is 38.5ºC and her respiratory rate is 30 breaths per minute.
During the examination, you observe that her left leg is warm and swollen with purple discoloration. On the back of her leg, her skin is peeling, and a deep, erythematosus, diffuse, grey soft wound is visible with white discharge.
When you ask her father about her medical history, he mentions that there was an outbreak of chickenpox at her school. He first noticed the wound on her leg three days ago.
Her Hb is 115 g/L (110-140), platelets are 140* 109/L (150 - 450), and WBC is 16 * 109/L (5-12 * 109).
What is the most likely complication?Your Answer: Necrotising fasciitis
Explanation:Chickenpox and its Complications
Chickenpox can lead to various complications, including invasive group A streptococcal soft tissue infections such as necrotizing fasciitis. This rare complication of the varicella-zoster virus causes painful lesions on the skin and underlying muscles, with systemic symptoms and open wounds. Diagnosis is made by passing a probe or gloved finger below the affected skin, causing it to separate from the underlying tissue.
Another complication caused by group A streptococcus is cellulitis, which affects the dermis and subcutaneous tissue. It presents with erythema, pain, swelling, and warmth, without systemic symptoms. Erysipelas, on the other hand, is a bacterial infection that affects the superficial layer of the dermis and commonly affects superficial cutaneous lymphatics. It presents similarly to cellulitis but has well-defined borders and can be a rare complication of chickenpox.
Henoch-Schonlein Purpura is an IgA-mediated vasculitis of the small vessels of the skin. It can rarely present as a complication of chickenpox with a widespread rash on the buttocks and lower thigh, abdominal pain, and joint pain. Reyes syndrome is another complication that commonly presents after a recent viral infection such as chickenpox. It is also thought to be triggered by aspirin use, which is often used to treat the symptoms of chickenpox, such as headaches. It presents with tachypnea, tiredness, and in severe cases can cause behavioral changes and coma. However, in this case, the patient only presents with tachypnea, and there is no evidence to suggest the use of aspirin.
Chickenpox: Causes, Symptoms, and Management
Chickenpox is a viral infection caused by the varicella zoster virus. It is highly contagious and can be spread through respiratory droplets. The virus can also reactivate later in life, causing shingles. Chickenpox is most infectious four days before the rash appears and until five days after the rash first appears. The incubation period is typically 10-21 days. Symptoms include fever, an itchy rash that starts on the head and trunk before spreading, and mild systemic upset.
Management of chickenpox is supportive and includes keeping cool, trimming nails, and using calamine lotion. School exclusion is recommended during the infectious period. Immunocompromised patients and newborns with peripartum exposure should receive varicella zoster immunoglobulin (VZIG). If chickenpox develops, IV acyclovir may be considered. Secondary bacterial infection of the lesions is a common complication, which may be increased by the use of NSAIDs. In rare cases, invasive group A streptococcal soft tissue infections may occur, resulting in necrotizing fasciitis. Other rare complications include pneumonia, encephalitis, disseminated haemorrhagic chickenpox, arthritis, nephritis, and pancreatitis.
Radiographic Findings in Varicella Pneumonia
Varicella pneumonia is a rare complication of chickenpox that can occur in immunocompromised patients or adults. Radiographic findings of healed varicella pneumonia may include miliary opacities throughout both lungs, which are of uniform size and dense, suggesting calcification. There is typically no focal lung parenchymal mass or cavitating lesion seen. These findings are characteristic of healed varicella pneumonia.

The consultant requests your assessment of a 4-week-old girl in the neonatal ward who was born prematurely at 28 weeks gestation. The infant is thriving, gaining weight appropriately, and appears pink and warm. Oxygen saturation is within normal limits, and lung sounds are clear. During cardiac auscultation, you note a continuous machinery murmur heard over the upper left sternal edge that does not vary with position or radiation. What is the most likely cause of this murmur?
Your Answer: Patent ductus arteriosus
Explanation:The child in question has an asymptomatic murmur that is not an innocent murmur since it does not vary with position. The continuous machinery murmur heard at the upper left sternal edge is indicative of patent ductus arteriosus, a condition that is most common in premature babies like this one. In utero, the ductus arteriosus is a connection between the pulmonary artery and the aorta that allows blood to bypass the lungs. Normally, it closes within two days after birth.
It’s worth noting that other conditions present differently. For example, pulmonary stenosis is characterized by an ejection systolic murmur over the left upper sternal edge, while coarctation of the aorta presents with a systolic murmur under the left scapula and in the left infraclavicular area.
Patent ductus arteriosus is a type of congenital heart defect that is typically classified as ‘acyanotic’. However, if left untreated, it can eventually lead to late cyanosis in the lower extremities, which is known as differential cyanosis. This condition is caused by a connection between the pulmonary trunk and descending aorta that fails to close with the first breaths due to increased pulmonary flow that enhances prostaglandins clearance. Patent ductus arteriosus is more common in premature babies, those born at high altitude, or those whose mothers had rubella infection during the first trimester of pregnancy.
The features of patent ductus arteriosus include a left subclavicular thrill, a continuous ‘machinery’ murmur, a large volume, bounding, collapsing pulse, a wide pulse pressure, and a heaving apex beat. To manage this condition, indomethacin or ibuprofen is given to the neonate, which inhibits prostaglandin synthesis and closes the connection in the majority of cases. If patent ductus arteriosus is associated with another congenital heart defect that is amenable to surgery, then prostaglandin E1 is useful to keep the duct open until after surgical repair.

Explanation:It is not recommended to exclude children from school due to head lice.
Understanding Head Lice
Head lice, also known as pediculosis capitis or ‘nits’, is a common condition in children caused by a parasitic insect called Pediculus capitis. These small insects live only on humans and feed on our blood. The eggs are glued to the hair close to the scalp and hatch in 7 to 10 days. Nits are the empty egg shells and are found further along the hair shaft as they grow out.
Head lice are spread by direct head-to-head contact and tend to be more common in children who play closely together. They cannot jump, fly, or swim. When newly infected, cases have no symptoms, but itching and scratching on the scalp occur 2 to 3 weeks after infection. There is no incubation period.
To diagnose head lice, fine-toothed combing of wet or dry hair is necessary. Treatment is only indicated if living lice are found. A choice of treatments should be offered, including malathion, wet combing, dimeticone, isopropyl myristate, and cyclomethicone. Household contacts of patients with head lice do not need to be treated unless they are also affected. School exclusion is not advised for children with head lice.
Understanding head lice is important to prevent its spread and manage the condition effectively. By knowing the symptoms, diagnosis, and management, we can take necessary precautions and seek appropriate treatment when needed.

You are attending labour for an emergency Caesarean section for failure to progress. The operation goes on without any complications. The baby cries immediately after birth and there is 30 seconds of delayed cord clamping. On examination, baby is centrally pink with blueish hands and feet. Saturation probes are attached to the baby and show an oxygen saturation of 73% at 5 minutes. What is the most appropriate next step in management?
Your Answer: Observe and reassess at next interval
Explanation:During the first 10 minutes after birth, it is normal for a healthy newborn to have SpO2 readings that are not optimal. It is also common for them to experience temporary cyanosis, which typically resolves on its own and does not require intervention. It is important to evaluate the baby’s appearance and color using the APGAR scoring system at 1 minute after birth, and then again at 5 and 10 minutes.
Cyanosis, a bluish discoloration of the skin, is a common occurrence in newborns. Peripheral cyanosis, which affects the hands and feet, is often seen in the first 24 hours of life and can be caused by crying or illness. Central cyanosis, on the other hand, is a more serious condition that occurs when the concentration of reduced hemoglobin in the blood exceeds 5g/dl. To differentiate between cardiac and non-cardiac causes of central cyanosis, doctors may use the nitrogen washout test, which involves giving the infant 100% oxygen for ten minutes and then measuring arterial blood gases. A pO2 of less than 15 kPa indicates cyanotic congenital heart disease, which can be caused by conditions such as tetralogy of Fallot, transposition of the great arteries, and tricuspid atresia.
If cyanotic congenital heart disease is suspected, initial management involves supportive care and the use of prostaglandin E1, such as alprostadil, to maintain a patent ductus arteriosus in ductal-dependent congenital heart defects. This can serve as a temporary measure until a definitive diagnosis is made and surgical correction is performed.
Acrocyanosis, a type of peripheral cyanosis, is a benign condition that is often seen in healthy newborns. It is characterized by bluish discoloration around the mouth and extremities, such as the hands and feet, and is caused by vasomotor changes that result in peripheral vasoconstriction and increased tissue oxygen extraction. Unlike other causes of peripheral cyanosis that may indicate significant pathology, such as septic shock, acrocyanosis occurs immediately after birth in healthy infants and typically resolves within 24 to 48 hours.

A father and his 6-year-old daughter visit your Child and Adolescent Mental Health Service (CAMHS) clinic, as she has recently been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). The father has already attended an educational program on ADHD and is feeling overwhelmed as his daughter's behavior is difficult to manage at home. He has heard that medication may be helpful. Based on previous interventions, what would be the next most suitable treatment for her ADHD?
Your Answer: Methylphenidate
Explanation:Methylphenidate is the recommended initial treatment for ADHD.
In March 2018, NICE released new guidelines for identifying and managing Attention Deficit Hyperactivity Disorder (ADHD). This condition can have a significant impact on a child’s life and can continue into adulthood, making accurate diagnosis and treatment crucial. According to DSM-V, ADHD is characterized by persistent features of inattention and/or hyperactivity/impulsivity, with an element of developmental delay. Children up to the age of 16 must exhibit six of these features, while those aged 17 or over must exhibit five. ADHD has a UK prevalence of 2.4%, with a higher incidence in boys than girls, and there may be a genetic component.
NICE recommends a holistic approach to treating ADHD that is not solely reliant on medication. After presentation, a ten-week observation period should be implemented to determine if symptoms change or resolve. If symptoms persist, referral to secondary care is necessary, typically to a paediatrician with a special interest in behavioural disorders or to the local Child and Adolescent Mental Health Service (CAMHS). A tailored plan of action should be developed, taking into account the patient’s needs and wants, as well as how their condition affects their lives.
Drug therapy should be considered a last resort and is only available to those aged 5 years or older. Parents of children with mild/moderate symptoms can benefit from attending education and training programmes. For those who do not respond or have severe symptoms, pharmacotherapy may be considered. Methylphenidate is the first-line treatment for children and should be given on a six-week trial basis. It is a CNS stimulant that primarily acts as a dopamine/norepinephrine reuptake inhibitor. Side effects include abdominal pain, nausea, and dyspepsia. Weight and height should be monitored every six months in children. If there is an inadequate response, lisdexamfetamine should be considered, followed by dexamfetamine if necessary. In adults, methylphenidate or lisdexamfetamine are the first-line options, with switching between drugs if no benefit is seen after a trial of the other. All of these drugs are potentially cardiotoxic, so a baseline ECG should be performed before starting treatment, and referral to a cardiologist should be made if there is any significant past medical history or family history, or any doubt or ambiguity.
As with most psychiatric conditions, a thorough history and clinical examination are essential, particularly given the overlap of ADHD with many other psychiatric and

A 4-week-old female neonate is brought to the hospital with a 1-week history of vomiting and regurgitation of non-bilious materials, mostly consisting of ingested milk. The vomiting has lately become projectile. On examination, an olive-shaped mass is palpated in the right upper quadrant, and a periodic wave of peristalsis is visible in the epigastric region. The neonate has puffy hands and feet and redundant skin in the neck. A systolic murmur is noted on the cardiac apex. Laboratory tests reveal hypokalaemic, hypochloraemic metabolic alkalosis.
What is the most likely diagnosis?Your Answer: Turner syndrome
Explanation:Differential Diagnosis for a Neonate with Hypertrophic Pyloric Stenosis and Other Symptoms
Hypertrophic pyloric stenosis is a condition that causes gastric outlet obstruction and is more common in neonates with Turner syndrome. Other symptoms in this scenario include puffy hands and feet due to lymphoedema, redundant skin in the neck due to early resolution of cystic hygroma, and a systolic murmur likely caused by coarctation of the aorta. Non-bilious vomiting distinguishes pyloric stenosis from duodenal atresia.
Congenital diaphragmatic hernia presents with vomiting, hypoxia, and a scaphoid abdomen, but is not typically associated with chromosomal abnormalities.
Down syndrome is characterized by flat and broad facies, epicanthal folds, simian creases, low-set ears, and a protruding tongue, but does not typically present with puffiness and redundant skin in the neck.
Duodenal atresia is associated with Down syndrome and presents with bilious vomiting, while this scenario involves non-bilious vomiting.
Tracheoesophageal fistula is associated with Down syndrome and VACTERL association, but does not typically present with puffiness and redundant skin in the neck.

A 10-year-old boy is the shortest in his class, measuring only 125 cm. His parents are worried about his growth. His last three recorded heights have been between the 0.4th and 2nd centile. His mother is 160 cm tall and his father is 175 cm tall. He has no other health issues.
What could be the probable reason for his short stature?Your Answer: Familial short stature
Explanation:Familial Short Stature in Children
Children who have short parents and are otherwise healthy may have familial short stature. This means that their height and weight fall within the expected range based on their parents’ heights, and growth charts can be used to predict their adult height. In the case of a girl with familial short stature, her predicted adult height would be 154 cm, which falls within the mid-parental range of heights. Delayed puberty would cause a failure to gain height at the beginning of puberty and crossing of height centiles, while inadequate nutrition would cause crossing of both height and weight centiles. Low birth weight can also cause short stature in children, but in the absence of any other history, familial short stature is the most likely explanation. Precocious puberty, on the other hand, causes children to be tall for their age at the onset of puberty, not short.

Question 104

A 7-year-old girl presents to the emergency department with sudden onset of shortness of breath. Her parents report that she had a cold for a few days but today her breathing has become more difficult. She has a history of viral-induced wheeze and was recently diagnosed with asthma by her GP.
Upon examination, her respiratory rate is 28/min, heart rate is 120/min, saturations are 95%, and temperature is 37.5ºC. She has intercostal and subcostal recession and a global expiratory wheeze, but responds well to salbutamol.
What medications should be prescribed for her acute symptoms upon discharge?Your Answer: Salbutamol inhaler + 3 days prednisolone PO
Explanation:It is recommended that all children who experience an acute exacerbation of asthma receive a short course of oral steroids, such as 3-5 days of prednisolone, along with a salbutamol inhaler. This approach should be taken regardless of whether the child is typically on an inhaled corticosteroid. It is important to ensure that patients have an adequate supply of their salbutamol inhaler and understand how to use it. Prescribing antibiotics is not necessary unless there is an indication of an underlying bacterial chest infection. Beclomethasone may be useful for long-term prophylactic management of asthma, but it is not typically used in short courses after acute exacerbations. A course of 10 days of prednisolone is longer than recommended and may not be warranted in all cases. A salbutamol inhaler alone would not meet the recommended treatment guidelines for acute asthma.
Managing Acute Asthma Attacks in Children
When it comes to managing acute asthma attacks in children, it is important to assess the severity of the attack and take appropriate action. For children between the ages of 2 and 5, those with severe or life-threatening asthma should be immediately transferred to the hospital. For moderate attacks, children should have a SpO2 level above 92% and no clinical features of severe asthma. However, for severe attacks, children may have a SpO2 level below 92%, be too breathless to talk or feed, have a heart rate above 140/min, and use accessory neck muscles. For life-threatening attacks, children may have a SpO2 level below 92%, a silent chest, poor respiratory effort, agitation, altered consciousness, and cyanosis.
For children over the age of 5, it is recommended to attempt to measure PEF in all cases. For moderate attacks, children should have a SpO2 level above 92%, a PEF level above 50% best or predicted, and no clinical features of severe asthma. For severe attacks, children may have a SpO2 level below 92%, a PEF level between 33-50% best or predicted, and be unable to complete sentences in one breath or too breathless to talk or feed. For life-threatening attacks, children may have a SpO2 level below 92%, a PEF level below 33% best or predicted, a silent chest, poor respiratory effort, altered consciousness, and cyanosis.
For children with mild to moderate acute asthma, bronchodilator therapy should be given via a beta-2 agonist and spacer (or close-fitting mask for children under 3 years old). One puff should be given every 30-60 seconds up to a maximum of 10 puffs. If symptoms are not controlled, the beta-2 agonist should be repeated and the child should be referred to the hospital. Steroid therapy should also be given to all children with an asthma exacerbation for 3-5 days, with the usual prednisolone dose varying based on age and weight.

A 4-year-old girl is brought to the emergency department by her father due to pain in her left hip. She has been complaining of pain and is hesitant to put weight on her left leg. She has a normal range of movement in both legs. Her father reports that she has been feeling sick with cold symptoms for the past few days and she currently has a temperature of 37.8 ºC.
What is the probable diagnosis?Your Answer: Transient synovitis
Explanation:Transient synovitis, also known as irritable hip, is a common cause of hip pain in children aged 3-8 years. It typically occurs following a recent viral infection and presents with symptoms such as groin or hip pain, limping or refusal to weight bear, and occasionally a low-grade fever. However, a high fever may indicate other serious conditions such as septic arthritis, which requires urgent specialist assessment. To exclude such diagnoses, NICE Clinical Knowledge Summaries recommend monitoring children in primary care with a presumptive diagnosis of transient synovitis, provided they are aged 3-9 years, well, afebrile, mobile but limping, and have had symptoms for less than 72 hours. Treatment for transient synovitis involves rest and analgesia, as the condition is self-limiting.

A 20-days-old infant is brought to the emergency department by his parents due to a distended abdomen and lethargy. The parents report a decrease in feeding over the past three days and repeated vomiting, with bilious vomit. The infant also had bloody stools this morning but no fever. He was born prematurely at 35 weeks due to premature rupture of membranes but is currently in good health. Based on the probable diagnosis, which investigation should be conducted?
Your Answer: Abdominal x-ray
Explanation:The preferred diagnostic test for necrotising enterocolitis is an abdominal x-ray. This condition, which is a leading cause of death among premature infants, presents with symptoms such as abdominal distension, feeding intolerance, bloody stool, and bilious vomiting. An abdominal x-ray can reveal dilated bowel loops, intramural gas, and portal venous gas. Treatment involves total gut rest and total parenteral nutrition, with laparotomy required for babies with perforations.
Intussusception is diagnosed using abdominal ultrasound, but this is unlikely in this case as the child does not have the characteristic symptoms of paroxysmal abdominal colic pain and red currant jelly stool. Laparotomy is used to investigate perforation, but this is unlikely as the child has no fever. Test feed is used to diagnose pyloric stenosis, but this is also unlikely as the child is presenting with multiple gastrointestinal symptoms. An upper gastrointestinal tract contrast study is used to diagnose malrotation, but this is unlikely as the child was born healthy.
Understanding Necrotising Enterocolitis
Necrotising enterocolitis is a serious condition that is responsible for a significant number of premature infant deaths. The condition is characterized by symptoms such as feeding intolerance, abdominal distension, and bloody stools. If left untreated, these symptoms can quickly progress to more severe symptoms such as abdominal discolouration, perforation, and peritonitis.
To diagnose necrotising enterocolitis, doctors often use abdominal x-rays. These x-rays can reveal a number of important indicators of the condition, including dilated bowel loops, bowel wall oedema, and intramural gas. Other signs that may be visible on an x-ray include portal venous gas, pneumoperitoneum resulting from perforation, and air both inside and outside of the bowel wall. In some cases, an x-ray may also reveal air outlining the falciform ligament, which is known as the football sign.
Overall, understanding the symptoms and diagnostic indicators of necrotising enterocolitis is crucial for early detection and treatment of this serious condition. By working closely with healthcare professionals and following recommended screening protocols, parents and caregivers can help ensure the best possible outcomes for premature infants at risk for this condition.

Which of the following is not a characteristic of Tetralogy of Fallot?
Your Answer: Atrial septal defect
Explanation:Understanding Tetralogy of Fallot
Tetralogy of Fallot (TOF) is a congenital heart disease that results from the anterior malalignment of the aorticopulmonary septum. It is the most common cause of cyanotic congenital heart disease, and it typically presents at around 1-2 months, although it may not be detected until the baby is 6 months old. The condition is characterized by four features, including ventricular septal defect (VSD), right ventricular hypertrophy, right ventricular outflow tract obstruction, and overriding aorta. The severity of the right ventricular outflow tract obstruction determines the degree of cyanosis and clinical severity.
Other features of TOF include cyanosis, which may cause episodic hypercyanotic ‘tet’ spells due to near occlusion of the right ventricular outflow tract. These spells are characterized by tachypnea and severe cyanosis that may occasionally result in loss of consciousness. They typically occur when an infant is upset, in pain, or has a fever, and they cause a right-to-left shunt. Additionally, TOF may cause an ejection systolic murmur due to pulmonary stenosis, and a right-sided aortic arch is seen in 25% of patients. Chest x-ray shows a ‘boot-shaped’ heart, while ECG shows right ventricular hypertrophy.
The management of TOF often involves surgical repair, which is usually undertaken in two parts. Cyanotic episodes may be helped by beta-blockers to reduce infundibular spasm. However, it is important to note that at birth, transposition of the great arteries is the more common lesion as patients with TOF generally present at around 1-2 months. Understanding the features and management of TOF is crucial for healthcare professionals to provide appropriate care and treatment for affected infants.

What are the typical vaccines administered to adolescents aged 12-19 years?
Your Answer: Tetanus/diphtheria/polio + Men ACWY
Explanation:The UK immunisation schedule recommends certain vaccines at different ages. At birth, the BCG vaccine is given if the baby is at risk of tuberculosis. At 2, 3, and 4 months, the ‘6-1 vaccine’ (diphtheria, tetanus, whooping cough, polio, Hib and hepatitis B) and oral rotavirus vaccine are given, along with Men B and PCV at certain intervals. At 12-13 months, the Hib/Men C, MMR, and PCV vaccines are given, along with Men B. At 3-4 years, the ‘4-in-1 preschool booster’ (diphtheria, tetanus, whooping cough and polio) and MMR vaccines are given. At 12-13 years, the HPV vaccination is given, and at 13-18 years, the ‘3-in-1 teenage booster’ (tetanus, diphtheria and polio) and Men ACWY vaccines are given. Additionally, the flu vaccine is recommended annually for children aged 2-8 years.
It is important to note that the meningitis ACWY vaccine has replaced meningitis C for 13-18 year-olds due to an increased incidence of meningitis W disease in recent years. The ACWY vaccine will also be offered to new students (up to the age of 25 years) at university. GP practices will automatically send letters inviting 17-and 18-year-olds in school year 13 to have the Men ACWY vaccine. Students going to university or college for the first time as freshers, including overseas and mature students up to the age of 25, should contact their GP to have the Men ACWY vaccine, ideally before the start of the academic year.
It is worth noting that the Men C vaccine used to be given at 3 months but has now been discontinued. This is because the success of the Men C vaccination programme means there are almost no cases of Men C disease in babies or young children in the UK any longer. All children will continue to be offered the Hib/Men C vaccine at one year of age, and the Men ACWY vaccine at 14 years of age to provide protection across all age groups.

A 6-month-old infant is brought to the Emergency Department with persistent vomiting for the past 2 days. The mother reports that the vomiting is forceful and occurs after every feed. Despite attempts to soothe the baby, the vomiting has not subsided. Upon examination, the infant appears to be in good health. The heart rate is 130 bpm, respiratory rate is 32/min, blood pressure is 95/65 mmHg, capillary refill is 2 seconds, and mucous membranes are slightly dry. The infant has no fever. The paediatric registrar is called to assess the infant and decides to admit the infant for further investigation. Which diagnostic test would be most helpful in determining the cause of the vomiting?
Your Answer: Abdominal ultrasound scan
Explanation:The baby in this situation displays typical indications of pyloric stenosis. If a young infant experiences projectile vomiting after each feeding, it is important to consider the possibility of pyloric stenosis. The most effective method to visualize the issue is through an ultrasound scan, which can identify the thickening of the circular pylorus muscles. This is also the safest and most straightforward diagnostic test for a young baby. Additionally, a thorough abdominal examination may uncover a detectable lump in the upper left quadrant.
Understanding Pyloric Stenosis
Pyloric stenosis is a condition that usually occurs in infants between the second and fourth weeks of life. However, in rare cases, it may present later, up to four months. This condition is caused by the thickening of the circular muscles of the pylorus. Pyloric stenosis is more common in males, with an incidence of 4 per 1,000 live births. It is also more likely to affect first-borns and infants with a positive family history.
The most common symptom of pyloric stenosis is projectile vomiting, which usually occurs about 30 minutes after a feed. Other symptoms may include constipation, dehydration, and a palpable mass in the upper abdomen. Prolonged vomiting can lead to hypochloraemic, hypokalaemic alkalosis, which can be life-threatening.
Diagnosis of pyloric stenosis is typically made using ultrasound. Management of this condition involves a surgical procedure called Ramstedt pyloromyotomy. This procedure involves making a small incision in the pylorus to relieve the obstruction and allow for normal passage of food. With prompt diagnosis and treatment, infants with pyloric stenosis can make a full recovery.

A couple, one male and one female, seek genetic counselling as a family member has been diagnosed with sickle cell anaemia, an autosomal recessive condition. After testing, it is discovered that both individuals are carriers of sickle cell anaemia. The woman is currently 16 weeks pregnant.
What is the likelihood that their unborn child will also be a carrier of sickle cell anaemia?Your Answer: 50%
Explanation:The statement is incorrect because if at least one parent is a carrier of sickle cell anemia, there is a probability greater than zero.
Understanding Autosomal Recessive Inheritance
Autosomal recessive inheritance is a genetic pattern where a disorder is only expressed when an individual inherits two copies of a mutated gene, one from each parent. This means that only homozygotes, individuals with two copies of the mutated gene, are affected. Both males and females are equally likely to be affected, and the disorder may not manifest in every generation, as it can skip a generation.
When two heterozygote parents, carriers of the mutated gene, have children, there is a 25% chance of having an affected (homozygote) child, a 50% chance of having a carrier (heterozygote) child, and a 25% chance of having an unaffected child. On the other hand, if one parent is homozygote for the gene and the other is unaffected, all the children will be carriers.
Autosomal recessive disorders are often metabolic in nature and can be life-threatening compared to autosomal dominant conditions. Understanding the inheritance pattern of autosomal recessive disorders is crucial in genetic counseling and family planning.

A 6-hour-old baby girl is assessed after being born at 37 weeks without any complications. The mother has not reported any issues and breastfeeding has been going smoothly. During the examination, the neonate appears to be in good condition. However, a blood glucose test reveals a reading of 2.0 mmol/L. What is the best course of action at this point?
Your Answer: Encourage continued breastfeeding
Explanation:Dextrose is not the correct treatment option, except in cases where the baby is symptomatic or has extremely low glucose levels.
Neonatal Hypoglycaemia: Causes, Symptoms, and Management
Neonatal hypoglycaemia is a common condition in newborn babies, especially in the first 24 hours of life. While there is no agreed definition, a blood glucose level of less than 2.6 mmol/L is often used as a guideline. Transient hypoglycaemia is normal and usually resolves on its own, but persistent or severe hypoglycaemia may be caused by various factors such as preterm birth, maternal diabetes mellitus, IUGR, hypothermia, neonatal sepsis, inborn errors of metabolism, nesidioblastosis, or Beckwith-Wiedemann syndrome.
Symptoms of neonatal hypoglycaemia can be autonomic, such as jitteriness, irritability, tachypnoea, and pallor, or neuroglycopenic, such as poor feeding/sucking, weak cry, drowsiness, hypotonia, and seizures. Other features may include apnoea and hypothermia. Management of neonatal hypoglycaemia depends on the severity of the condition and whether the newborn is symptomatic or not. Asymptomatic babies can be encouraged to feed normally and have their blood glucose monitored, while symptomatic or severely hypoglycaemic babies may need to be admitted to the neonatal unit and receive intravenous infusion of 10% dextrose.

A mother brings her 12-year-old boy into the Emergency Department. She is concerned as he has started to limp over the last few days and is in pain. There is no history of trauma; he has no temperature and is otherwise well. You notice he is overweight for his age.
Which is the most likely diagnosis?Your Answer: Slipped femoral epiphysis
Explanation:Pediatric Hip Conditions: Slipped Femoral Epiphysis, Perthes’ Disease, Septic Arthritis, and Juvenile Idiopathic Arthritis
Hip conditions in children can present with a variety of symptoms and causes. One common condition is slipped femoral epiphysis, which typically affects boys aged 10-16 who are overweight. Symptoms include a painful limp, limited internal rotation, and displacement of the femoral head on X-ray. Treatment involves surgical fixation.
Another condition is Perthes’ disease, which is avascular necrosis of the femoral head and typically affects younger children aged 4-10, more commonly in boys. Symptoms include an intermittent limp and limited joint movement. Treatment can be medical or surgical, but surgery may result in limb shortening and a permanent limp.
Septic arthritis presents with an acutely painful, inflamed, and swollen joint, often with fever. It is more common in patients with underlying joint disease or a history of trauma. Musculoskeletal back pain is unlikely in this scenario.
Juvenile idiopathic arthritis is an autoimmune inflammatory joint disease seen in children under 16. It presents with joint swelling, morning pain, limping, lethargy, reduced activity, and poor appetite, and is associated with anterior uveitis and spiking fevers. However, it is unlikely in this scenario due to the chronicity of symptoms and the child’s overall health.
In conclusion, pediatric hip conditions can have various causes and symptoms, and proper diagnosis and treatment are crucial for optimal outcomes.

As a doctor, you have been requested by a midwife to conduct a newborn examination on a 24-hour old infant. During the examination, the parents express concern about their baby's penis appearing abnormal and request your assistance. Upon inspection, you observe that the urethral meatus is situated on the ventral aspect of the glans and the prepuce is hooded. However, the baby has already passed urine with a strong stream, as noted by the midwife earlier in the day. What should be the doctor's next course of action?
Your Answer: Refer to a specialist for possible surgery around 12 months of life
Explanation:It is recommended to refer a child with hypospadias to a specialist for possible surgery around the age of 12 months. This timing is considered optimal, taking into account various factors such as developmental milestones, tolerance of surgery and anesthesia, and the size of the penis. It is important to refer the child to a specialist at the time of diagnosis. Referring a child for surgery within the first month of life or within four hours is not necessary, as this is not an urgent or life-threatening issue. Hypospadias always requires a specialist referral, even if it is mild, and it is the specialist’s responsibility, along with the parents, to decide whether surgery is necessary. It is crucial to advise parents not to circumcise their child with hypospadias, as the prepuce may be used during corrective surgery.
Understanding Hypospadias: A Congenital Abnormality of the Penis
Hypospadias is a condition that affects approximately 3 out of 1,000 male infants. It is a congenital abnormality of the penis that is usually identified during the newborn baby check. However, if missed, parents may notice an abnormal urine stream. This condition is characterized by a ventral urethral meatus, a hooded prepuce, and chordee in more severe forms. The urethral meatus may open more proximally in the more severe variants, but 75% of the openings are distally located. There appears to be a significant genetic element, with further male children having a risk of around 5-15%.
Hypospadias most commonly occurs as an isolated disorder, but it can also be associated with other conditions such as cryptorchidism (present in 10%) and inguinal hernia. Once hypospadias has been identified, infants should be referred to specialist services. Corrective surgery is typically performed when the child is around 12 months of age. It is essential that the child is not circumcised prior to the surgery as the foreskin may be used in the corrective procedure. In boys with very distal disease, no treatment may be needed. Understanding hypospadias is important for parents and healthcare providers to ensure proper management and treatment of this condition.

You are working in a district general hospital and are asked to perform a routine check on a 6-month-old infant. You're part of the paediatric team and haven't had any access to the previous medical records.
On examination, the infant appears healthy with appropriate weight for age and has a strong cry. There are no signs of respiratory distress and no abnormal heart sounds on auscultation. However, you notice a cleft palate. What is the most likely association with this finding?Your Answer: Maternal anti-epileptic use in pregnancy
Explanation:The use of anti-epileptic medication by expectant mothers can lead to the development of orofacial clefts in their babies. Orofacial clefts are a common birth defect that can be caused by various factors, including smoking, benzodiazepine use, anti-epileptic medication, and rubella infection during pregnancy. Treatment for orofacial clefts requires a team of specialists, including plastic and orthodontic surgeons, paediatricians, and speech therapists. It is important to note that congenital heart disease does not increase the risk of orofacial clefts.
Understanding Cleft Lip and Palate
Cleft lip and palate are common congenital deformities that affect approximately 1 in every 1,000 babies. These conditions can occur as isolated developmental malformations or as a component of over 200 birth defects. The most common variants of cleft lip and palate are isolated cleft lip, isolated cleft palate, and combined cleft lip and palate.
The pathophysiology of cleft lip and palate involves polygenic inheritance and an increased risk for babies whose mothers use antiepileptic medication. Cleft lip occurs when the fronto-nasal and maxillary processes fail to fuse, while cleft palate results from the failure of the palatine processes and nasal septum to fuse.
Children with cleft lip and palate may experience problems with feeding and speech. Orthodontic devices can be helpful for feeding, while speech therapy can help 75% of children develop normal speech. Babies with cleft palate are at an increased risk of developing otitis media.
Management of cleft lip and palate involves repairing the cleft lip earlier than the cleft palate. The timing of repair varies, with some practices repairing the cleft lip in the first week of life and others waiting up to three months. Cleft palates are typically repaired between 6-12 months of age.

A 32-week neonate is brought to the neonatal intensive care unit. The baby was delivered via emergency Caesarean section to a 17-year-old mother who had not received adequate antenatal care. The mother had a history of significant tobacco and alcohol use. During examination, it was observed that the baby had intestinal loops protruding through a hole on the left side of the umbilicus. What is the probable diagnosis?
Your Answer: Gastroschisis
Explanation:Socioeconomic deprivation, maternal alcohol/tobacco use, and maternal age under 20 are all associated with gastroschisis.
While gastroschisis and omphalocele have similar presentations, gastroschisis refers to a defect located to the side of the umbilicus, while omphalocele refers to a defect in the umbilicus itself.
Foetal alcohol syndrome is characterized by a small head, flattened philtrum, and thin upper lip.
Anencephaly is a neural tube defect that results in the absence of the brain, skull, and scalp.
Gastroschisis and exomphalos are both types of congenital visceral malformations. Gastroschisis refers to a defect in the anterior abdominal wall located just beside the umbilical cord. In contrast, exomphalos, also known as omphalocoele, involves the protrusion of abdominal contents through the anterior abdominal wall, which are covered by an amniotic sac formed by amniotic membrane and peritoneum.
When it comes to managing gastroschisis, vaginal delivery may be attempted, but newborns should be taken to the operating theatre as soon as possible after delivery, ideally within four hours. As for exomphalos, a caesarean section is recommended to reduce the risk of sac rupture. In cases where primary closure is difficult due to lack of space or high intra-abdominal pressure, a staged repair may be undertaken. This involves allowing the sac to granulate and epithelialise over several weeks or months, forming a shell. As the infant grows, the sac contents will eventually fit within the abdominal cavity, at which point the shell can be removed and the abdomen closed.
Overall, both gastroschisis and exomphalos require careful management to ensure the best possible outcome for the newborn. By understanding the differences between these two conditions and the appropriate steps to take, healthcare professionals can provide effective care and support to both the infant and their family.

A 13-year-old girl visits her GP with worries about not having started her periods yet, unlike her peers. During the examination, the GP notes that she is 143cm tall and has several melanocytic naevi on her arms. She also holds her arms at a wide carrying angle when at rest. There is no relevant family history and her cardiovascular examination is normal. What is the probable diagnosis?
Your Answer: Turner's syndrome
Explanation:Understanding Turner’s Syndrome
Turner’s syndrome is a genetic disorder that affects approximately 1 in 2,500 females. It is caused by the absence of one sex chromosome (X) or a deletion of the short arm of one of the X chromosomes. This condition is denoted as 45,XO or 45,X.
The features of Turner’s syndrome include short stature, a shield chest with widely spaced nipples, a webbed neck, a bicuspid aortic valve (15%), coarctation of the aorta (5-10%), primary amenorrhea, cystic hygroma (often diagnosed prenatally), a high-arched palate, a short fourth metacarpal, multiple pigmented naevi, lymphoedema in neonates (especially feet), and elevated gonadotrophin levels. Hypothyroidism is much more common in Turner’s syndrome, and there is also an increased incidence of autoimmune disease (especially autoimmune thyroiditis) and Crohn’s disease.
In summary, Turner’s syndrome is a chromosomal disorder that affects females and can cause a range of physical features and health issues. Early diagnosis and management can help individuals with Turner’s syndrome lead healthy and fulfilling lives.

A 3-month-old baby was brought to the emergency department three days ago with a purpuric rash, fever, vomiting, and reduced wet nappies. During the assessment, the baby had a seizure which resolved on its own. The baby was admitted and tested for meningitis. A lumbar puncture was done and the laboratory results showed elevated protein levels, increased white cells, and a gram-positive organism. What is the appropriate course of action for managing this infant?
Your Answer: IV amoxicillin and IV cefotaxime
Explanation:In the case of suspected or confirmed bacterial meningitis in children under 3 months old, corticosteroids should not be used. For an infant with lumbar puncture results indicating bacterial meningitis, a combination of IV amoxicillin and IV cefotaxime is the appropriate antibiotic choice to cover both gram positive and gram negative bacteria until a specific pathogen is identified. Prescribing only amoxicillin would not provide sufficient coverage. It is crucial to administer antibiotics in this situation and not withhold treatment.
Investigation and Management of Meningitis in Children
Meningitis is a serious condition that can affect children. When investigating meningitis, it is important to note any contraindications to lumbar puncture, such as signs of raised intracranial pressure, focal neurological signs, papilloedema, significant bulging of the fontanelle, disseminated intravascular coagulation, or signs of cerebral herniation. For patients with meningococcal septicaemia, a lumbar puncture is contraindicated, and blood cultures and PCR for meningococcal should be obtained instead.
The management of meningitis in children involves administering antibiotics, such as IV amoxicillin (or ampicillin) and IV cefotaxime for children under three months, and IV cefotaxime (or ceftriaxone) for children over three months. Steroids should be considered if the lumbar puncture reveals certain findings, such as purulent cerebrospinal fluid, a high white blood cell count, or bacteria on Gram stain. Fluids should be administered to treat shock, and cerebral monitoring should be conducted, including mechanical ventilation if necessary.
It is also important to notify public health authorities and administer antibiotic prophylaxis to contacts. Ciprofloxacin is now preferred over rifampicin for this purpose. Overall, prompt and appropriate management of meningitis in children is crucial for ensuring the best possible outcomes.

A newborn baby, delivered via C-section at term, has been diagnosed with a ventricular septal defect (VSD) and is being reviewed by cardiology. The mother is feeling anxious and wants to know what risks her son may face. What is the high-risk factor associated with VSD in newborns?
Your Answer: Endocarditis
Explanation:Patients with VSD may require surgical intervention if their defect causes haemodynamic instability, while those with small shunts may not require treatment. However, all patients with VSD are at an increased risk of developing endocarditis, with a rate of 2.4 cases per 1000 patients per year. While pulmonary hypertension is common in patients with VSD, they are not at a higher risk of developing essential hypertension. Although VSD is associated with aneurysms of the ventricular septum, there is no known link to aortic aneurysms, carotid dissection, or papillary muscle atrophy.
Congenital heart disease can be categorized into two types: acyanotic and cyanotic. Acyanotic heart diseases are more common and include ventricular septal defects (VSD), atrial septal defect (ASD), patent ductus arteriosus (PDA), coarctation of the aorta, and aortic valve stenosis. VSD is the most common acyanotic heart disease, accounting for 30% of cases. ASDs are less common than VSDs, but they are more frequently diagnosed in adult patients as they tend to present later. On the other hand, cyanotic heart diseases are less common and include tetralogy of Fallot, transposition of the great arteries (TGA), and tricuspid atresia. Fallot’s is more common than TGA, but TGA is the more common lesion at birth as patients with Fallot’s generally present at around 1-2 months. The presence of cyanosis in pulmonary valve stenosis depends on the severity and any other coexistent defects.

You assess an 11-year-old girl who has been experiencing worsening constipation for the past 3 years, despite previously having regular bowel movements. All other aspects of her medical history and physical examination are unremarkable. She is not currently taking any medications.
What would be the appropriate next course of action in managing her constipation?Your Answer: Osmotic laxative
Explanation:Constipation at this age is most likely caused by dietary factors. Therefore, it is important to offer dietary guidance, such as increasing fiber and fluid consumption. Additionally, advising the individual to increase their activity level may be beneficial. As the constipation is getting worse, a laxative would be helpful. An osmotic laxative is recommended initially, as the stool is expected to be hard. A stimulant laxative may be necessary once the stool has softened.
Understanding and Managing Constipation in Children
Constipation is a common problem in children, with the frequency of bowel movements decreasing as they age. The National Institute for Health and Care Excellence (NICE) has provided guidelines for the diagnosis and management of constipation in children. A diagnosis of constipation is suggested by two or more symptoms, including infrequent bowel movements, hard stools, and associated distress or pain. Most cases of constipation in children are idiopathic, but other causes such as dehydration, low-fiber diet, and medication use should be considered and excluded.
If a diagnosis of constipation is made, NICE recommends assessing for faecal impaction before starting treatment. Treatment for faecal impaction involves using polyethylene glycol 3350 + electrolytes (Movicol Paediatric Plain) as the first-line treatment, with the addition of a stimulant laxative if necessary. Maintenance therapy involves a similar regime, with adjustments to the starting dose and the addition of other laxatives if necessary.
It is important to note that dietary interventions alone are not recommended as first-line treatment, although ensuring adequate fluid and fiber intake is important. Regular toileting and non-punitive behavioral interventions should also be considered. For infants, extra water, gentle abdominal massage, and bicycling the legs can be helpful for constipation. If these measures are not effective, lactulose can be added.
In summary, constipation in children can be managed effectively with a combination of medication, dietary adjustments, and behavioral interventions. It is important to follow NICE guidelines and consider the individual needs of each child.

A 14-year-old male from the Roma community presents to his GP with symptoms of cough, rhinorrhoea, sore throat, fever and a rash. He has no significant medical history and is not taking any medications. He recently arrived from Romania. On examination, he has a maculopapular rash on his face, serous discharge from his eyes, and small white lesions on his buccal mucosa. There is no tonsillar exudate or evidence of meningism. Cardio-respiratory and abdominal examinations are unremarkable. What is the most likely diagnosis?
Your Answer: Measles
Explanation:The patient’s symptoms, including cough, conjunctivitis, fever, and a rash with Koplik spots, suggest a diagnosis of measles. Measles is characterized by these symptoms, as well as a maculopapular rash that starts behind the ears. The presence of Koplik spots is a key indicator of measles. It is worth noting that some groups, such as the Roma community, have lower rates of vaccination against measles, mumps, and rubella.
Epstein Barr virus is an incorrect answer. While it can cause fever and sore throat, it is less likely to present with a rash and Koplik spots. Instead, cervical lymphadenopathy is a more prominent feature. Palatal petechiae may be visible early on.
Rubella is also an incorrect answer. While it can cause a rash on the face, there is no presence of Koplik spots. Additionally, fever tends to be less severe. Post-auricular and suboccipital lymphadenopathy may be present.
Scarlet fever is another incorrect answer. The rash associated with scarlet fever typically starts on the abdomen and spreads to the back and limbs. Sore throat is a prominent symptom, and there may be tonsillar exudate. Cough is not typically present, and a strawberry tongue may be visible.
Measles: A Highly Infectious Viral Disease
Measles is a viral disease caused by an RNA paramyxovirus. It is one of the most infectious known viruses and is spread through aerosol transmission. The disease has an incubation period of 10-14 days and is infective from the prodromal phase until four days after the rash starts. Measles is now rare in developed countries due to immunization programs, but outbreaks can occur when vaccination rates drop, such as during the MMR controversy of the early 2000s.
The disease is characterized by a prodromal phase, which includes irritability, conjunctivitis, fever, and Koplik spots. The latter typically develop before the rash and are white spots on the buccal mucosa. The rash starts behind the ears and then spreads to the whole body, becoming a discrete maculopapular rash that may become blotchy and confluent. Desquamation may occur after a week, typically sparing the palms and soles. Diarrhea occurs in around 10% of patients.
Measles is mainly managed through supportive care, and admission may be considered in immunosuppressed or pregnant patients. The disease is notifiable, and public health should be informed. Complications of measles include otitis media, pneumonia (the most common cause of death), encephalitis (typically occurring 1-2 weeks following the onset of the illness), subacute sclerosing panencephalitis (very rare, may present 5-10 years following the illness), febrile convulsions, keratoconjunctivitis, corneal ulceration, diarrhea, increased incidence of appendicitis, and myocarditis.
If an unimmunized child comes into contact with measles, MMR should be offered within 72 hours. Vaccine-induced measles antibody develops more rapidly than that following natural infection.

A 10-year-old boy is brought to surgery due to persistent leg pains. Which one of the following would not be consistent with a diagnosis of 'growing pains'?
Your Answer: Present upon waking in the morning
Explanation:Understanding Growing Pains in Children
Growing pains are a common complaint among children aged 3-12 years. These pains are often attributed to ‘benign idiopathic nocturnal limb pains of childhood’ in rheumatology, as they are not necessarily related to growth. Boys and girls are equally affected by growing pains, which are characterized by intermittent pain in the legs without obvious cause.
One of the key features of growing pains is that they are never present at the start of the day after the child has woken up. Additionally, there is no limp or limitation of physical activity, and the child is systemically well with normal physical examination and motor milestones. Symptoms may worsen after a day of vigorous activity.
Overall, growing pains are a benign condition that can be managed with reassurance and simple measures such as massage or heat application. However, it is important to rule out other potential causes of leg pain in children, especially if there are any worrying features present.

A 12-year-old girl visits the doctor with her mother, worried about not having started her periods yet. During the examination, it is observed that she has normal female genitalia but bilateral inguinal hernias. Additionally, she has breast buds and minimal pubic and axillary hair. The girl's weight and IQ are both within the normal range for her age. What is the probable underlying reason for her concern?
Your Answer: Complete androgen insensitivity
Explanation:Primary amenorrhoea can be caused by conditions such as Turner syndrome, where the absence of ovaries and uterus leads to underdeveloped inguinal hernias containing immature testes. Aromatase can cause breast bud development and sparse pubic hair, while the lack of menstruation is due to the absence of reproductive organs. Anorexia nervosa is not indicated in this case, as it typically presents with a low body mass index, distorted body image, and extreme dietary or exercise habits. Polycystic ovarian syndrome (PCOS) is a possible cause of secondary amenorrhoea, often seen in patients with a high BMI, irregular menses, hyperandrogenism, and multiple ovarian follicles. If the patient had PCOS, other signs of hyperandrogenism, such as hirsutism or acne, would be expected. Pregnancy is another cause of secondary amenorrhoea.
Disorders of sex hormones can have various effects on the body, as shown in the table below. Primary hypogonadism, also known as Klinefelter’s syndrome, is characterized by high levels of LH and low levels of testosterone. Patients with this disorder often have small, firm testes, lack secondary sexual characteristics, and are infertile. They may also experience gynaecomastia and have an increased risk of breast cancer. Diagnosis is made through chromosomal analysis.
Hypogonadotrophic hypogonadism, or Kallmann syndrome, is another cause of delayed puberty. It is typically inherited as an X-linked recessive trait and is caused by the failure of GnRH-secreting neurons to migrate to the hypothalamus. Patients with Kallmann syndrome may have hypogonadism, cryptorchidism, and anosmia. Sex hormone levels are low, and LH and FSH levels are inappropriately low or normal. Cleft lip/palate and visual/hearing defects may also be present.
Androgen insensitivity syndrome is an X-linked recessive condition that causes end-organ resistance to testosterone, resulting in genotypically male children (46XY) having a female phenotype. Complete androgen insensitivity syndrome is the new term for testicular feminisation syndrome. Patients with this disorder may experience primary amenorrhoea, undescended testes causing groin swellings, and breast development due to the conversion of testosterone to oestradiol. Diagnosis is made through a buccal smear or chromosomal analysis to reveal a 46XY genotype. Management includes counseling to raise the child as female, bilateral orchidectomy due to an increased risk of testicular cancer from undescended testes, and oestrogen therapy.

A concerned father brings his 6-year-old daughter to see the GP, worried about her walking and balance. The child learned to walk around 2 years old, much the same as her older brother. However, over the last few months, her dad has noticed that she has become reluctant to walk and often trips or falls when she does.
On examination, the child is of average build but has disproportionately large calves. When asked to walk across the room she does so on her tiptoes. Gowers test is positive.
What investigation is considered most appropriate to confirm the likely diagnosis?Your Answer: Genetic analysis
Explanation:A diagnosis of Duchenne muscular dystrophy (DMD) can now be made through genetic testing instead of a muscle biopsy. The symptoms and history described strongly suggest DMD, which is a genetic disorder that causes muscle wasting and weakness. Classic features of DMD include calf hyperplasia and a positive Gowers test. Most individuals with DMD will require a wheelchair by puberty, and management is primarily conservative. CT imaging of the legs is not typically used for diagnosis, and while a high creatine kinase can indicate muscular dystrophy in children, genetic testing is more definitive. Muscle function testing is useful for monitoring disease progression but not for initial diagnosis.
Understanding Duchenne Muscular Dystrophy
Duchenne muscular dystrophy is a genetic disorder that is inherited in an X-linked recessive manner. It affects the dystrophin genes that are essential for normal muscular function. The disorder is characterized by progressive proximal muscle weakness that typically begins around the age of 5 years. Other features include calf pseudohypertrophy and Gower’s sign, which is when a child uses their arms to stand up from a squatted position. Approximately 30% of patients with Duchenne muscular dystrophy also have intellectual impairment.
To diagnose Duchenne muscular dystrophy, doctors typically look for elevated levels of creatinine kinase in the blood. However, genetic testing has now replaced muscle biopsy as the preferred method for obtaining a definitive diagnosis. Unfortunately, there is currently no effective treatment for Duchenne muscular dystrophy, so management is largely supportive.
The prognosis for Duchenne muscular dystrophy is poor. Most children with the disorder are unable to walk by the age of 12 years, and patients typically survive to around the age of 25-30 years. Duchenne muscular dystrophy is also associated with dilated cardiomyopathy, which can further complicate the management of the disorder.

A 7-month-old girl has been referred to you by the out of hours GP. Her parents report a 24-hour history of increased work of breathing, coryzal symptoms, lethargy, and reduced oral intake. Upon examination, you observe fine inspiratory crackles and subcostal recessions. She has a fever of 38.1ºC and her oxygen saturations are 92% in air.
What would be the most suitable next step to take?Your Answer: Admit for observation and oxygen therapy
Explanation:If your child is experiencing any of the following symptoms, seek medical attention immediately:
– High fever (over 102°F or 39°C)
– Severe dehydration (signs include dry mouth, sunken eyes, and decreased urine output)
– Persistent severe respiratory distress, such as grunting, significant chest recession, or a respiratory rate exceeding 70 breaths per minute.It is important to ensure your child is drinking enough fluids to avoid dehydration.
Bronchiolitis is a condition where the bronchioles become inflamed, and it is most commonly caused by respiratory syncytial virus (RSV). This virus is responsible for 75-80% of cases, with other causes including mycoplasma and adenoviruses. Bronchiolitis is most prevalent in infants under one year old, with 90% of cases occurring in those aged 1-9 months. The condition is more serious in premature babies, those with congenital heart disease or cystic fibrosis. Symptoms include coryzal symptoms, dry cough, increasing breathlessness, and wheezing. Hospital admission is often necessary due to feeding difficulties associated with increasing dyspnoea.
Immediate referral is recommended if the child has apnoea, looks seriously unwell, has severe respiratory distress, central cyanosis, or persistent oxygen saturation of less than 92% when breathing air. Clinicians should consider referral if the child has a respiratory rate of over 60 breaths/minute, difficulty with breastfeeding or inadequate oral fluid intake, or clinical dehydration. Immunofluorescence of nasopharyngeal secretions may show RSV, and management is largely supportive. Humidified oxygen is given via a head box if oxygen saturations are persistently low, and nasogastric feeding may be necessary if children cannot take enough fluid/feed by mouth. Suction may also be used for excessive upper airway secretions. NICE released guidelines on bronchiolitis in 2015 for more information.

A 9-year-old girl presents to the Emergency department with a three day history of limping. She has been experiencing illness recently. Upon examination, she has no fever and shows discomfort when moving her hip. What is the probable diagnosis?
Your Answer: Transient synovitis
Explanation:Transient Synovitis in Childhood: the Causes and Diagnosis
Transient synovitis is a prevalent cause of hip pain in children, but it is crucial to rule out other more severe causes before diagnosing it. The exact cause of this condition is still unknown, but it is believed to be associated with viral infections, allergic reactions, or trauma.
Transient synovitis is a self-limiting condition that typically resolves within a few days to weeks. However, it is essential to differentiate it from other conditions that may require urgent medical attention, such as septic arthritis or Legg-Calve-Perthes disease. Therefore, a thorough medical history, physical examination, and imaging studies are necessary to make an accurate diagnosis.
In conclusion, transient synovitis is a common cause of hip pain in childhood, but it is crucial to exclude other more serious conditions before diagnosing it. Parents should seek medical attention if their child experiences hip pain, limping, or difficulty walking to ensure prompt and appropriate treatment.

You are working in the pediatric unit and examine a 6-month-old infant. On examination, you observe a small left-sided hematoma over the parietal bone. The hematoma is soft to touch and does not extend beyond the margins of the parietal bone. The infant is otherwise healthy. The infant was born at term via spontaneous vaginal delivery, and there were no prenatal or labor complications. What is the probable diagnosis?
Your Answer: Cephalhaematoma
Explanation:Medical students may mistake a cephalhaematoma for a caput succedaneum, but there are distinguishing features. Cephalhaematomas typically develop after birth and do not cross the skull’s suture lines, as the blood is contained between the skull and periosteum. Caput succedaneum, on the other hand, is an extraperiosteal collection of blood that can cross over the suture lines and may be present at birth. Subaponeurotic haemorrhages are a serious condition caused by bleeding in the potential space between the periosteum and subgaleal aponeurosis. They typically present as a boggy swelling that grows insidiously and is not confined to the skull sutures. In severe cases, the neonate may experience haemorrhagic shock. Chignons are birth traumas that occur after the use of a ventouse device during delivery, while a cranial abrasion usually occurs after a caesarean section or instrumental delivery.
A cephalohaematoma is a swelling that appears on a newborn’s head, usually a few hours after delivery. It is caused by bleeding between the skull and periosteum, with the parietal region being the most commonly affected site. This condition may lead to jaundice as a complication and can take up to three months to resolve.
In comparison to caput succedaneum, which is another type of swelling that can occur on a newborn’s head, cephalohaematoma is more localized and does not cross suture lines. Caput succedaneum, on the other hand, is a diffuse swelling that can cross suture lines and is caused by fluid accumulation in the scalp tissue. Both conditions are usually harmless and resolve on their own, but medical attention may be necessary in severe cases.

A 4-month old baby presents with a murmur and cyanosis. What is the most probable diagnosis?
Your Answer: Fallot's tetralogy
Explanation:Causes of Cyanotic Congenital Cardiac Disease
Cyanotic congenital cardiac disease is a condition that causes a lack of oxygen in the body, resulting in a blue or purple discoloration of the skin. The most common cause of this condition that does not present in the first few days of life is Fallot’s tetralogy. However, transposition of the great arteries is almost as common, but it presents in the first few days. Other causes of cyanotic congenital cardiac disease include tricuspid atresia, single ventricle, and transposition of the great vessels. As the condition progresses, Eisenmenger’s syndrome may develop due to the switch to right to left flow associated with deteriorating VSD. It is important to identify and treat these conditions early to prevent further complications.

A 7-year-old is brought in by his father who is worried about his son's right hip pain that has been ongoing for the past 7 weeks. The father reports that the pain has been getting worse and is now causing his son to wake up at night. Over the last week, he has noticed his son limping and having difficulty getting in and out of the car and bathtub.
What is the probable diagnosis?Your Answer: Perthes' disease
Explanation:Perthes disease is characterized by avascular necrosis of the femoral head, leading to progressive hip pain, stiffness, and limp. It typically affects children between the ages of 4-8 years and can take 2-3 years to heal. Slipped upper femoral epiphysis, which affects overweight or tall thin adolescents, and developmental dysplasia present differently. Transient synovitis of the hip, which resolves within 7-10 days, is not likely due to the absence of a preceding viral illness. Septic joint is also unlikely based on the given information.
Understanding Perthes’ Disease
Perthes’ disease is a degenerative condition that affects the hip joints of children, typically between the ages of 4-8 years. It is caused by a lack of blood supply to the femoral head, which leads to bone infarction and avascular necrosis. This condition is more common in boys, with around 10% of cases being bilateral. The symptoms of Perthes’ disease include hip pain, stiffness, reduced range of hip movement, and a limp. Early changes can be seen on an x-ray, such as widening of the joint space, while later changes include decreased femoral head size and flattening.
To diagnose Perthes’ disease, a plain x-ray is usually sufficient. However, if symptoms persist and the x-ray is normal, a technetium bone scan or magnetic resonance imaging may be necessary. If left untreated, Perthes’ disease can lead to complications such as osteoarthritis and premature fusion of the growth plates.
The severity of Perthes’ disease is classified using the Catterall staging system, which ranges from stage 1 (clinical and histological features only) to stage 4 (loss of acetabular integrity). Treatment options include keeping the femoral head within the acetabulum using a cast or braces, observation for children under 6 years old, and surgical management for older children with severe deformities. The prognosis for Perthes’ disease is generally good, with most cases resolving with conservative management. Early diagnosis is key to improving outcomes.

Which statement regarding ventricular septal defect (VSD) is correct?
Your Answer: There may be a diastolic murmur at the apex
Explanation:Ventricular Septal Defects
Ventricular septal defects (VSDs) are a type of congenital heart defect that can cause a diastolic murmur. This murmur can occur due to aortic incompetence or increased flow across the mitral valve, which can lead to relative mitral stenosis. In some cases, right to left shunting can occur, which can cause cerebral abscesses.
While large VSDs may be associated with soft murmurs, pulmonary hypertension can occur in association with increased flow across the shunt. However, it may also indicate decreased flow across the shunt and increased pulmonary vascular resistance, which can result in a softer murmur.
It’s important to note that the risk of bacterial endocarditis is high in individuals with VSDs, even those with haemodynamically trivial lesions. Therefore, it’s crucial to monitor and manage this condition carefully.

A 22-year-old woman brings her 8-week-old baby to an emergency GP appointment. The mother reports that her baby is extremely fussy in the evenings, crying incessantly and pulling up their legs. The baby was delivered vaginally at full term and is exclusively breastfed. The baby's weight is normal and there are no other health concerns. Upon examination, everything appears to be normal. What course of action would you suggest?
Your Answer: Reassurance and support
Explanation:Understanding Infantile Colic
Infantile colic is a common condition that affects infants under three months old. It is characterized by excessive crying and pulling up of the legs, which is often worse in the evening. This condition affects up to 20% of infants, and its cause is unknown.
Despite its prevalence, there is no known cure for infantile colic. However, there are some remedies that parents can try to alleviate the symptoms. NICE Clinical Knowledge Summaries advise against the use of simethicone or lactase drops, such as Infacol® and Colief®, respectively. These remedies have not been proven to be effective in treating infantile colic.
Parents can try other methods to soothe their baby, such as holding them close, rocking them gently, or using a pacifier. Some parents also find that white noise or music can help calm their baby. It is important to remember that infantile colic is a temporary condition that usually resolves on its own by the time the baby is three to four months old.

A 7-year-old girl is brought to the pediatrician by her father. For the past few days, she has been experiencing pain while walking. Her father is concerned as this has never happened before and he cannot think of any reason for it.
During the examination, the girl refuses to walk. Her vital signs are stable, except for a temperature of 38ºC. On examining her legs, there is no visible inflammation, but the left hip is tender. When attempting to move the left leg, the child screams in pain. The right leg appears to be normal. She has no medical history and is not taking any medications.
What is the most appropriate management for the most likely diagnosis?Your Answer: Advise to attend the emergency department
Explanation:If a child is experiencing hip pain or a limp and has a fever, it is important to refer them for same-day assessment, even if the suspected diagnosis is transient synovitis.
The correct course of action in this case is to advise the patient to attend the emergency department. Although the patient appears to be well, the presence of a fever raises concerns about septic arthritis, which can cause long-term complications. Further investigations cannot be performed in a general practice setting, making it necessary to seek urgent medical attention.
Advising the patient to attend a local minor injury unit is not appropriate, as the staff there would most likely transfer the patient to an emergency department, causing unnecessary delays. Similarly, arranging an urgent orthopaedic outpatient appointment is not appropriate in this acute situation.
Prescribing aspirin and providing a safety net is not a suitable option, as aspirin should never be given to children due to the risk of Reye’s syndrome. It is also unwise to exclude septic arthritis without further supporting evidence.
Finally, growing pains are an unlikely diagnosis in this case, as they are typically bilateral and do not interfere with daily activities.
Transient synovitis, also known as irritable hip, is a common cause of hip pain in children aged 3-8 years. It typically occurs following a recent viral infection and presents with symptoms such as groin or hip pain, limping or refusal to weight bear, and occasionally a low-grade fever. However, a high fever may indicate other serious conditions such as septic arthritis, which requires urgent specialist assessment. To exclude such diagnoses, NICE Clinical Knowledge Summaries recommend monitoring children in primary care with a presumptive diagnosis of transient synovitis, provided they are aged 3-9 years, well, afebrile, mobile but limping, and have had symptoms for less than 72 hours. Treatment for transient synovitis involves rest and analgesia, as the condition is self-limiting.

A 35-year-old woman attends an ultrasound scan at 36 weeks due to gestational hypertension. This shows a breech presentation. She has a successful external cephalic version (ECV) at 37 weeks and her baby is born vaginally at 40+5 weeks. On the initial postnatal check, both Ortolani's and Barlow's tests are negative. Mums' blood pressure returns to normal after birth.
What investigations will be necessary?Your Answer: Ultrasound hips of baby at 6 weeks
Explanation:At 6 weeks, the mother will undergo a 2-hour oral glucose tolerance test (OGTT) with a glucose load of 75g.
Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be bilateral in 20% of cases. Screening for DDH is recommended for infants with certain risk factors, and all infants are screened using the Barlow and Ortolani tests at the newborn and six-week baby check. Clinical examination includes testing for leg length symmetry, restricted hip abduction, and knee level when hips and knees are flexed. Ultrasound is used to confirm the diagnosis if clinically suspected, but x-ray is the first line investigation for infants over 4.5 months. Management includes the use of a Pavlik harness for children under 4-5 months and surgery for older children with unstable hips.

When would a social services referral be indicated in the first instance?Your Answer: If you suspect a child is being maltreated or you feel the family could benefit from some extra support
Explanation:When to Make a Referral to Social Services for Child Protection
As a healthcare professional, it is important to know when to make a referral to social services for child protection. Here are some situations that require immediate action:
1. Suspected maltreatment or need for extra support: If you suspect a child is being maltreated or you feel the family could benefit from some extra support, a referral must be made urgently to social services. Follow up within 48 hours with written confirmation.
2. Immediate danger: If you feel a child needs to be removed from premises immediately for their safety, inform the police immediately. Once the child is considered to be in a place of safety, social services will be informed.
3. Recent sexual assault: If the child has disclosed a recent sexual assault, they would need to be referred urgently for forensic examination. Following this, social services will be likely to be informed.
4. Discussion with safeguarding lead: If you feel confident in your judgement, you do not have to seek advice from the safeguarding lead before every referral. If you suspect a child is at risk of harm, it is your responsibility to take action to ensure the child’s safety.
5. Consent of parent and/or patient: Always try to gain consent from the parent or patient before making a referral to social services. If consent is refused, the referral can still be made, but it is important that the patient/parent is fully informed of your actions.

A three-year-old child is admitted to the hospital with a high fever of 39ºC that has persisted for the past five days. The parents are worried as they have noticed redness in the child's eyes, swelling in the neck, and a new rash.
During the examination, the child is found to have a widespread maculopapular rash and bilateral conjunctivitis. Additionally, there is unilateral cervical lymphadenopathy, cracked and erythematosus lips, and a strawberry tongue.
What is the initial treatment that should be given to this three-year-old child?Your Answer: Aspirin
Explanation:Kawasaki disease is a systemic vasculitis that typically affects children under the age of 5. Symptoms include a fever lasting over 5 days, bilateral non-purulent conjunctivitis, a rash, mucosal erythema with a strawberry tongue, and unilateral cervical lymphadenopathy. In some cases, swelling of the hands and feet can occur, followed by desquamation in the second week. If left untreated, up to one-quarter of patients can develop coronary aneurysms. The main goal of treatment is to reduce the risk of cardiac complications. In the UK, the standard treatment is intravenous immunoglobulin and high dose aspirin, despite the fact that aspirin is usually contraindicated in children. Benzylpenicillin is not indicated in the treatment of Kawasaki disease. Conservative management is also not appropriate, as specific treatment is required to reduce inflammation and prevent the risk of coronary complications. Corticosteroids may be used as a second-line treatment if the patient does not respond to intravenous immunoglobulins.
Understanding Kawasaki Disease
Kawasaki disease is a rare type of vasculitis that primarily affects children. It is important to identify this disease early on as it can lead to serious complications, such as coronary artery aneurysms. The disease is characterized by a high-grade fever that lasts for more than five days and is resistant to antipyretics. Other symptoms include conjunctival injection, bright red, cracked lips, strawberry tongue, cervical lymphadenopathy, and red palms and soles that later peel.
Diagnosis of Kawasaki disease is based on clinical presentation as there is no specific diagnostic test available. Management of the disease involves high-dose aspirin, which is one of the few indications for aspirin use in children. Intravenous immunoglobulin is also used as a treatment option. Echocardiogram is the initial screening test for coronary artery aneurysms, rather than angiography.
Complications of Kawasaki disease can be serious, with coronary artery aneurysm being the most common. It is important to recognize the symptoms of Kawasaki disease early on and seek medical attention promptly to prevent potential complications.

A 4-year-old boy visits his pediatrician complaining of a new rash that has spread all over his body. Upon further inquiry, it is discovered that he had been experiencing a high fever, fatigue, conjunctivitis, and a mild cough for the past four days. During the last week, he had been experiencing these symptoms. Upon examination, the pediatrician notices small white spots on the inside of the boy's cheeks. What is the probable diagnosis?
Your Answer: Measles
Explanation:Symptoms of Measles
The initial symptoms of measles, known as the prodrome, include a high fever, cough, malaise, conjunctivitis, and coryza. Additionally, the buccal mucosa may develop white punctate lesions, which are referred to as Koplik spots. As the maculopapular cutaneous rash begins to appear, these spots fade away. The rash typically starts on the face and upper neck before spreading to the extremities. These symptoms are considered pathognomonic for measles, and the Koplik spots often disappear as the macular rash becomes more prominent. Overall, recognizing these symptoms is crucial for early diagnosis and treatment of measles.

A 7-month-old infant is brought to the emergency department with symptoms of vomiting, blood in stools, and irritability. During the physical examination, the baby's abdomen is found to be tense, and he draws his knees up in response to palpation.
What would be the most suitable course of action for this baby?Your Answer: Refer to paediatric surgeons
Explanation:Intussusception in Children: Diagnosis and Treatment
Intussusception is a medical condition that occurs when one part of the intestine slides into another part, causing a blockage. Children with this condition may experience severe abdominal pain, vomiting, and bloody stools. If left untreated, intussusception can lead to bowel perforation, sepsis, and even death. Therefore, it is crucial to diagnose and treat this condition promptly.
When a child presents with symptoms of intussusception, the most appropriate course of action is to refer them immediately to a paediatric surgical unit. There, doctors will attempt to relieve the intussusception through air reduction, which involves pumping air into the intestine to push the telescoped section back into place. If this method fails, surgery may be necessary to correct the blockage.
Several risk factors can increase a child’s likelihood of developing intussusception, including viral infections and intestinal lymphadenopathy. Therefore, parents should seek medical attention if their child experiences any symptoms of this condition. With prompt diagnosis and treatment, most children with intussusception can make a full recovery.

A mother observes that her 2-year-old son has small eye openings, a small body, and low-set ears. During the examination, the pediatrician also observes a flat philtrum, a sunken nasal bridge, short palpebral fissures, and a thin upper lip. What could be the probable cause of these symptoms?
Your Answer: Maternal alcohol abuse
Explanation:Fetal alcohol syndrome is a condition that occurs when a mother abuses alcohol during pregnancy. This can lead to various physical and developmental abnormalities in the fetus, including intrauterine growth restriction, small head size, underdeveloped midface, small jaw, a smooth ridge between the nose and upper lip, small eye openings, and a thin upper lip. Affected infants may also exhibit irritability and attention deficit hyperactivity disorder (ADHD).
Understanding Fetal Alcohol Syndrome
Fetal alcohol syndrome is a condition that occurs when a pregnant woman consumes alcohol, which can lead to various physical and mental abnormalities in the developing fetus. At birth, the baby may exhibit symptoms of alcohol withdrawal, such as irritability, hypotonia, and tremors.
The features of fetal alcohol syndrome include a short palpebral fissure, a thin vermillion border or hypoplastic upper lip, a smooth or absent philtrum, learning difficulties, microcephaly, growth retardation, epicanthic folds, and cardiac malformations. These physical characteristics can vary in severity and may affect the child’s overall health and development.
It is important for pregnant women to avoid alcohol consumption to prevent fetal alcohol syndrome and other potential complications. Early diagnosis and intervention can also help improve outcomes for children with fetal alcohol syndrome. By understanding the risks and consequences of alcohol use during pregnancy, we can work towards promoting healthier pregnancies and better outcomes for children.

Question 138
Correct

A 24-hour-old newborn, born at 35 weeks to a healthy mother, is currently being examined on the ward. The baby appears to be in good health on initial inspection and the mother has not reported any concerns thus far. During the examination, the doctor observes a large volume, collapsing pulse, a heaving apex beat, and a left subclavicular thrill. On auscultation of heart sounds, the doctor detects a continuous 'machinery-like' murmur. An urgent echocardiogram is ordered by the doctor, which confirms their suspected diagnosis. No other abnormalities or defects are detected on the echo.
What would be the most appropriate initial management, given the findings and likely diagnosis?Your Answer: Give indomethacin to the neonate
Explanation:The probable diagnosis based on the examination findings is pulmonary ductus arteriosus (PDA), which is characterized by a ‘machinery-like’ murmur. The recommended treatment for this condition is the administration of indomethacin or ibuprofen, which inhibits prostaglandin production and promotes duct closure. The use of prostaglandin E1 is not appropriate in this case, as it would keep the duct open. Referral for routine or urgent surgery is also not necessary, as no other congenital heart defects were found on the echocardiogram. Monitoring and repeating echocardiograms alone are not sufficient and medical intervention is required for closure of the duct.
Patent ductus arteriosus is a type of congenital heart defect that is typically classified as ‘acyanotic’. However, if left untreated, it can eventually lead to late cyanosis in the lower extremities, which is known as differential cyanosis. This condition is caused by a connection between the pulmonary trunk and descending aorta that fails to close with the first breaths due to increased pulmonary flow that enhances prostaglandins clearance. Patent ductus arteriosus is more common in premature babies, those born at high altitude, or those whose mothers had rubella infection during the first trimester of pregnancy.
The features of patent ductus arteriosus include a left subclavicular thrill, a continuous ‘machinery’ murmur, a large volume, bounding, collapsing pulse, a wide pulse pressure, and a heaving apex beat. To manage this condition, indomethacin or ibuprofen is given to the neonate, which inhibits prostaglandin synthesis and closes the connection in the majority of cases. If patent ductus arteriosus is associated with another congenital heart defect that is amenable to surgery, then prostaglandin E1 is useful to keep the duct open until after surgical repair.

A 36 hour old neonate is presented to the GP by the parents due to the absence of bowel movement since birth at home and vomiting of yellow/green liquid after feeding. During the examination, the child's stomach appears significantly distended, but no palpable masses are detected. What is the gold standard diagnostic test for the probable diagnosis?
Your Answer: Barium enema
Correct Answer: Rectal biopsy
Explanation:Understanding Hirschsprung’s Disease
Hirschsprung’s disease is a rare condition that affects 1 in 5,000 births. It is caused by a developmental failure of the parasympathetic Auerbach and Meissner plexuses, resulting in an aganglionic segment of bowel. This leads to uncoordinated peristalsis and functional obstruction, which can present as constipation and abdominal distension in older children or failure to pass meconium in the neonatal period.
Hirschsprung’s disease is three times more common in males and is associated with Down’s syndrome. Diagnosis is made through a rectal biopsy, which is considered the gold standard. Treatment involves initial rectal washouts or bowel irrigation, followed by surgery to remove the affected segment of the colon.
In summary, Hirschsprung’s disease is a rare condition that can cause significant gastrointestinal symptoms. It is important to consider this condition as a differential diagnosis in childhood constipation, especially in male patients or those with Down’s syndrome. Early diagnosis and treatment can improve outcomes and prevent complications.

A 2-year-old girl presents with bilious vomiting, abdominal distension and has been constipated since birth and did not pass meconium until she was 3 days old. Height and weight are at the fifth percentile. On examination, the abdomen is distended and a PR examination causes stool ejection. What is the probable diagnosis?
Your Answer: Hirschsprung disease
Explanation:Hirschsprung disease is a bowel disease that is present at birth and is more common in boys than girls, occurring five times more frequently. The typical symptoms include vomiting of bile, swelling of the abdomen, difficulty passing stool, and failure to pass meconium within the first two days of life. However, in some cases, the disease may not become apparent until later in childhood or adolescence. A colon biopsy is used to diagnose the condition, which reveals a segment of bowel that lacks nerve cells.

A 10-month-old infant is brought to the emergency department by her mother. She has had a barking cough for the past 2 days and her mother says she has been eating poorly for the past 3 days. During examination, the infant appears calm and is easily entertained by her toys. The barking cough is audible even at rest and there is slight sternal retraction. Vital signs are stable. The diagnosis is croup and treatment is initiated. What is the most appropriate initial treatment for this infant?
Your Answer: Nebulised salbutamol
Correct Answer: Oral dexamethasone
Explanation:The infant’s condition is stable.
If oral administration is not possible, IV hydrocortisone may be required, but it is not the preferred option.
Antibiotics are not the primary treatment for croup as it is mostly caused by a viral infection.Understanding Croup: A Respiratory Infection in Infants and Toddlers
Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.
The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.
Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.
Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

A 15-year-old boy is presented to the General Practitioner by his mother who reports that he has been having difficulties at school for the past year. The patient has a medical history of recurrent otitis media. The mother mentions that her nephew and niece have both required extra assistance at school, and the latter has been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). The patient had a normal birth history and early childhood development. On examination, he has an elongated face and protruding ears. What is the most probable diagnosis?
Your Answer: Down's syndrome
Correct Answer: Fragile X syndrome
Explanation:Fragile X Syndrome: A Genetic Disorder
Fragile X syndrome is a genetic disorder caused by a trinucleotide repeat. It affects both males and females, but males are more severely affected. Common features in males include learning difficulties, large low set ears, long thin face, high arched palate, macroorchidism, hypotonia, and a higher likelihood of autism. Mitral valve prolapse is also a common feature. Females, who have one fragile chromosome and one normal X chromosome, may have a range of symptoms from normal to mild.
Diagnosis of Fragile X syndrome can be made antenatally by chorionic villus sampling or amniocentesis. The number of CGG repeats can be analyzed using restriction endonuclease digestion and Southern blot analysis. Early diagnosis and intervention can help manage the symptoms of Fragile X syndrome and improve the quality of life for those affected.

A 6-year-old boy is brought to the GP surgery by his mother. He has a two-year history of asthma which has previously been controlled with a salbutamol inhaler twice daily and beclomethasone 50 micrograms bd. He has an audible wheeze that has been gradually worsening over the last few weeks and has not responded to additional doses of salbutamol. His mother also reports that he has a night-time cough for the past 6 weeks.
What is the most appropriate next step in management?Your Answer: Add a trial of a leukotriene receptor antagonist
Explanation:If a child under the age of 5 has asthma that is not being controlled by a short-acting beta agonist (SABA) and a low dose of inhaled corticosteroids (ICS), then a leukotriene receptor antagonist should be added to their asthma management plan.
Managing Asthma in Children: NICE Guidelines
Asthma management in children has been updated by NICE in 2017, following the 2016 BTS guidelines. The new guidelines for children aged 5-16 are similar to those for adults, with a stepwise approach for treatment. For newly-diagnosed asthma, short-acting beta agonist (SABA) is recommended. If symptoms persist, a combination of SABA and paediatric low-dose inhaled corticosteroid (ICS) is used. Leukotriene receptor antagonist (LTRA) is added if symptoms still persist, followed by long-acting beta agonist (LABA) if necessary. Maintenance and reliever therapy (MART) is used as a combination of ICS and LABA for daily maintenance therapy and symptom relief. For children under 5 years old, clinical judgement plays a greater role in diagnosis. The stepwise approach is similar to that for older children, with an 8-week trial of paediatric moderate-dose ICS before adding LTRA. If symptoms persist, referral to a paediatric asthma specialist is recommended.
It should be noted that NICE does not recommend changing treatment for well-controlled asthma patients simply to adhere to the latest guidelines. The definitions of low, moderate, and high-dose ICS have also changed, with different definitions for adults and children. For children, <= 200 micrograms budesonide or equivalent is considered a paediatric low dose, 200-400 micrograms is a moderate dose, and > 400 micrograms is a high dose. Overall, the new NICE guidelines provide a clear and concise approach to managing asthma in children.

A 3-year-old girl is brought to the Emergency Department, during the autumn period, with severe dyspnoea at rest. She has been unwell for the past week with a barking cough and inspiratory stridor which are typically worse in the late evening. On examination, intercostal and subdiaphragmatic recessions are noticeable. A chest radiograph shows tapering of the upper trachea.
What is the most probable pathogen responsible for this girl's condition?Your Answer: Streptococcus pyogenes
Correct Answer: Parainfluenza virus
Explanation:The most likely cause of this patient’s dyspnoea at rest, combined with being generally unwell and the time of year, is croup. Croup is commonly caused by the parainfluenza virus. Bordetella pertussis, Parvovirus B19, and Respiratory syncytial virus are unlikely causes as they present with different symptoms and are associated with different conditions.

A 6-year-old male is brought to his pediatrician by his father who is worried that he may have an infection. He reports that for the past 5 days his son has been scratching his anal and genital area, especially at night. He has also noticed some 'white threads' in his son's stool which he is very concerned about.
What is the most suitable course of action based on the probable diagnosis?Your Answer: Single dose of oral mebendazole for the daughter only and hygiene advice
Correct Answer: Single dose of oral mebendazole for the entire household and hygiene advice
Explanation:The most likely diagnosis in this case is a threadworm infection, which commonly affects young children and can cause anal and vulval itching. Threadworms can be seen in faeces and appear as white thread-like pieces. The recommended first-line treatment for threadworm infection is a single dose of mebendazole, and it is advised that all members of the household receive treatment due to the high risk of transmission. In addition to medication, hygiene measures such as frequent hand-washing, washing of bedding and towels, and disinfecting surfaces should also be recommended. It is important to note that hygiene advice alone is not sufficient to eradicate the infection. Administering mebendazole to only the affected individual or for a prolonged period of time is also incorrect.
Threadworm Infestation in Children
Threadworm infestation, caused by Enterobius vermicularis or pinworms, is a common occurrence among children in the UK. The infestation happens when eggs present in the environment are ingested. In most cases, threadworm infestation is asymptomatic, but some possible symptoms include perianal itching, especially at night, and vulval symptoms in girls. Diagnosis can be made by applying Sellotape to the perianal area and sending it to the laboratory for microscopy to see the eggs. However, most patients are treated empirically, and this approach is supported in the CKS guidelines.
The CKS recommends a combination of anthelmintic with hygiene measures for all members of the household. Mebendazole is the first-line treatment for children over six months old, and a single dose is given unless the infestation persists. It is essential to treat all members of the household to prevent re-infection. Proper hygiene measures, such as washing hands regularly, keeping fingernails short, and washing clothes and bedding at high temperatures, can also help prevent the spread of threadworm infestation.

A 16-month-old boy has been diagnosed with roseola infantum. What is the most frequent complication associated with this illness?
Your Answer: Otitis media with effusion
Correct Answer: Febrile convulsions
Explanation:Understanding Roseola Infantum
Roseola infantum, also known as exanthem subitum or sixth disease, is a common illness that affects infants and is caused by the human herpes virus 6 (HHV6). This disease has an incubation period of 5-15 days and is typically seen in children aged 6 months to 2 years. The most common symptoms of roseola infantum include a high fever that lasts for a few days, followed by a maculopapular rash. Other symptoms may include Nagayama spots, which are papular enanthems on the uvula and soft palate, as well as cough and diarrhea.
In some cases, febrile convulsions may occur in around 10-15% of children with roseola infantum. While this can be concerning for parents, it is important to note that this is a common occurrence and typically resolves on its own. Additionally, HHV6 infection can lead to other possible consequences such as aseptic meningitis and hepatitis.
It is important to note that school exclusion is not necessary for children with roseola infantum. While this illness can be uncomfortable for infants, it is typically not serious and resolves on its own within a few days.

A 10-year-old boy with Down's syndrome, asthma, reflux, and hyperthyroidism is brought to the GP by his mother due to concerns about his chronic snoring. What could be the potential cause of his snoring based on his medical history?
Your Answer: Previous tonsillectomy
Correct Answer: Down's syndrome
Explanation:Children who have Down’s syndrome are susceptible to snoring due to their low muscle tone in the upper airways, large tongue/adenoids, and increased risk of obesity. On the other hand, gastroesophageal reflux disease is not connected to snoring, but it can worsen at night and cause coughing. Tonsillectomy is a common treatment for snoring as it eliminates enlarged tonsils that can obstruct the upper airway. Hypothyroidism, not hyperthyroidism, is linked to snoring.
Snoring in Children: Possible Causes
Snoring in children can be caused by various factors. One of the common causes is obesity, which can lead to the narrowing of the airways and difficulty in breathing during sleep. Another possible cause is nasal problems such as polyps, deviated septum, and hypertrophic nasal turbinates, which can also obstruct the airways and cause snoring. Recurrent tonsillitis can also contribute to snoring, as the inflamed tonsils can block the air passages.
In some cases, snoring in children may be associated with certain medical conditions such as Down’s syndrome and hypothyroidism. These conditions can affect the structure and function of the respiratory system, leading to snoring and other breathing difficulties.
It is important to identify the underlying cause of snoring in children and seek appropriate treatment to prevent potential health complications. Parents should consult a healthcare professional if their child snores regularly or experiences other symptoms such as daytime sleepiness, difficulty concentrating, or behavioral problems.

A 4-year-old girl with cerebral palsy comes to the GP with her father for a check-up. Upon examination, she has a delay in her overall development. She is not yet able to walk or crawl, but she can use her fingers to pick up objects and is happily playing with toys during the visit. She can say a few words, such as mom and dad. During the examination, you notice some bruises on her abdomen, left elbow, and right forearm. Her father explains that these bruises are due to her clumsiness and he is concerned that she will continue to hurt herself. He mentions that her mother had a similar condition that required oral steroids and wonders if his daughter has developed the same condition.
What is the next step in managing this patient?Your Answer: Reassure and discharge
Correct Answer: Same-day paediatric assessment
Explanation:Immediate paediatric assessment is necessary for a non-mobile infant with multiple bruises, as this could indicate non-accidental injury. Bruising near the trunk, cheeks, ears, or buttocks should also be considered red flags. Coagulation screen and coagulopathy testing may be performed later, but the priority is to assess for potential abuse. Oral prednisolone is not first-line for children with immune thrombocytopenia (ITP) and reassurance and discharge are not appropriate in this situation.
Recognizing Child Abuse: Signs and Symptoms
Child abuse is a serious issue that can have long-lasting effects on a child’s physical and emotional well-being. It is important to be able to recognize the signs and symptoms of child abuse in order to intervene and protect the child. One possible indicator of abuse is when a child discloses abuse themselves. However, there are other factors that may point towards abuse, such as an inconsistent story with injuries, repeated visits to A&E departments, delayed presentation, and a frightened, withdrawn appearance known as frozen watchfulness.
Physical presentations of child abuse can also be a sign of abuse. These may include bruising, fractures (especially metaphyseal, posterior rib fractures, or multiple fractures at different stages of healing), torn frenulum (such as from forcing a bottle into a child’s mouth), burns or scalds, failure to thrive, and sexually transmitted infections like Chlamydia, gonorrhoeae, and Trichomonas. It is important to be aware of these signs and symptoms and to report any concerns to the appropriate authorities to ensure the safety and well-being of the child.

The mother of a 3-year-old child is worried about her child's developmental progress. Upon assessment, you observe that the child can only build a tower of five blocks at most and can only speak in two to three-word phrases. What is the typical age range for a healthy child to achieve these developmental milestones?
Your Answer: 3 years
Correct Answer: 2 ½ years
Explanation:Developmental Delay in Children
Developmental delay in children can be a cause for concern, especially when they fail to meet certain milestones at their age. For instance, a 4-year-old child should be able to speak in full sentences, play interactively, and build structures with building blocks. However, when a child exhibits a degree of developmental delay, it could be due to various factors such as neurological and neurodevelopmental problems like cerebral palsy and epilepsy, unmet physical and psychological needs, sensory impairment, genetic conditions like Down’s syndrome, and ill health.
It is important to understand the causes of developmental delay in children to provide appropriate interventions and support. Parents and caregivers should observe their child’s development and seek professional help if they notice any delays or abnormalities. Early intervention can help address developmental delays and improve a child’s overall well-being. By the factors that contribute to developmental delay, we can work towards creating a supportive environment that promotes healthy growth and development in children.

A 7-year-old boy is presented to the Emergency department with a sudden onset of limping. He denies any history of injury, but experiences pain in his right hip with any movement. Additionally, his temperature is 37.5°C. What investigation would have the greatest impact on your management plan in the next few hours?
Your Answer: Right hip ultrasound scan (USS)
Correct Answer: Full blood count (FBC) and C reactive protein (CRP)
Explanation:Assessing Orthopaedic Infection Risk in Limping Children
In order to assess the risk of orthopaedic infection in a limping child, it is important to consider the most likely diagnoses, which include septic arthritis, osteomyelitis, and trauma. If the child is apyrexial, the risk of septic arthritis is low, but it is still important to measure inflammatory markers and white cell count before considering further testing. If these markers are elevated, blood cultures should be taken and an ultrasound scan performed to look for an effusion that could be aspirated. If the markers are normal, the diagnosis is likely to be transient synovitis of the hip.
In older apyrexial children, bilateral AP hip x-rays may be performed to investigate for slipped upper femoral epiphysis, although this is rare in children under 8 years old. By carefully assessing the child’s symptoms and conducting appropriate tests, healthcare professionals can accurately diagnose and treat orthopaedic infections in limping children.

You are requested to assess a neonate who is 6 hours old and has been experiencing intermittent grunting and occasional nasal flaring. The baby was delivered this morning through an elective Caesarean section at 41 weeks gestation. The respiratory rate and oxygen saturation of the baby are both normal. The mother is worried as her previous child, who was also born through Caesarean section, had a similar presentation. What guidance would you provide to the mother?
Your Answer: The baby needs a chest x-ray
Correct Answer: No further treatment or investigation is currently required
Explanation:The primary treatment for uncomplicated transient tachypnoea of the newborn (TTN) involves observation and supportive care, along with the possible use of oxygen. This condition is frequently observed in babies delivered via Caesarean section, but in most cases, no additional treatment or testing is necessary if the baby is healthy. TTN typically resolves on its own, and parents should be reassured accordingly. Antibiotics, supplemental oxygen, and chest imaging are not typically required unless symptoms worsen. Additionally, TTN is not linked to any genetic predisposition or cause.
Understanding Transient Tachypnoea of the Newborn
Transient tachypnoea of the newborn (TTN) is a common respiratory condition that affects newborns. It is caused by the delayed resorption of fluid in the lungs, which can lead to breathing difficulties. TTN is more common in babies born via caesarean section, as the fluid in their lungs may not be squeezed out during the birth process. A chest x-ray may show hyperinflation of the lungs and fluid in the horizontal fissure.
The management of TTN involves observation and supportive care. In some cases, supplementary oxygen may be required to maintain oxygen saturation levels. However, TTN usually resolves within 1-2 days. It is important for healthcare professionals to monitor newborns with TTN closely and provide appropriate care to ensure a full recovery. By understanding TTN and its management, healthcare professionals can provide the best possible care for newborns with this condition.

A baby boy is born after 29 weeks gestation. On day three, a routine examination reveals a continuous mechanical murmur and bounding femoral pulses. Echocardiography confirms a haemodynamically significant, isolated patent ductus arteriosus (PDA). What should be the next step in managing this condition?
Your Answer: Medical management - prostaglandin infusion
Correct Answer: Medical management - cyclooxygenase inhibitor infusion
Explanation:Management of Patent Ductus Arteriosus
The ductus arteriosus is a fetal blood vessel that directs deoxygenated blood from the right ventricle directly into the descending aorta. After birth, the ductus should close within the first few days due to decreased prostaglandin levels and increased oxygen concentrations. Premature and low birth weight babies are at a higher risk of the ductus remaining open, which can lead to complications such as reduced blood supply to tissues, pressure overload of the pulmonary circulation, and volume overload of the systemic circulation.
The decision to intervene and close a patent ductus arteriosus (PDA) is based on the individual case and the severity of the condition. Medical management is usually the first step and involves administering a cyclooxygenase inhibitor to block prostaglandin synthesis and promote closure of the ductus. Conservative management may be an option for PDAs of little consequence, but even small PDAs pose long-term risks and may require intervention. Cardiac catheterisation is not appropriate in isolated PDA cases, and surgical management is reserved for those who fail medical management. Prostaglandin infusions may be used to keep the ductus patent in certain cardiac malformations that require a shunt for survival.
Overall, the management of PDA is crucial in preventing complications and ensuring proper blood flow. The decision to intervene should be made on a case-by-case basis, with medical management being the usual first step.

A 15-year-old girl presents to your clinic with worries about delayed menarche. Upon taking her medical history, you find no developmental issues. She is currently at the 65th percentile for weight and 5th percentile for height. During the physical examination, you observe a short webbed neck and broad chest. After conducting a karyotype analysis, you discover an abnormality. What is the most prevalent heart condition linked to this clinical presentation?
Your Answer: Mitral valve prolapse
Correct Answer: Bicuspid aortic valve
Explanation:The most frequently observed cardiac defect in individuals with Turner’s syndrome (45 XO) is a bicuspid aortic valve, which is more prevalent than coarctation of the aorta. Additionally, aortic root dilation and coarctation of the aorta are also associated with this condition.
Understanding Turner’s Syndrome
Turner’s syndrome is a genetic disorder that affects approximately 1 in 2,500 females. It is caused by the absence of one sex chromosome (X) or a deletion of the short arm of one of the X chromosomes. This condition is denoted as 45,XO or 45,X.
The features of Turner’s syndrome include short stature, a shield chest with widely spaced nipples, a webbed neck, a bicuspid aortic valve (15%), coarctation of the aorta (5-10%), primary amenorrhea, cystic hygroma (often diagnosed prenatally), a high-arched palate, a short fourth metacarpal, multiple pigmented naevi, lymphoedema in neonates (especially feet), and elevated gonadotrophin levels. Hypothyroidism is much more common in Turner’s syndrome, and there is also an increased incidence of autoimmune disease (especially autoimmune thyroiditis) and Crohn’s disease.
In summary, Turner’s syndrome is a chromosomal disorder that affects females and can cause a range of physical features and health issues. Early diagnosis and management can help individuals with Turner’s syndrome lead healthy and fulfilling lives.

As an F1 doctor on a paediatric ward, you come across a 9-year-old girl with her parents. She has been diagnosed with West syndrome and is part of a research trial that requires regular EEG recordings. While discussing her progress during the ward round, the girl interrupts and expresses her dislike for the 'horrible head stickers'. She becomes visibly upset when the trial is mentioned. What would be the best course of action in this situation?
Your Answer: Remove the child from the trial immediately
Correct Answer: Raise your concerns with your consultant about the child's obvious objections in being involved with the trial
Explanation:It is unprofessional to disregard the concerns regarding the patient’s participation in the trial. As an F1 doctor, it would be an extreme measure to remove the child from the trial or report the matter to the GMC without consulting a senior colleague first. It would be advisable to discuss the parents’ comprehension of the trial, but it would be more appropriate to approach the consultant initially, as they would have more knowledge of the research being conducted. The GMC guidelines also state that children and young people should not be involved in research if they object or appear to object, even if their parents provide consent.
Guidelines for Obtaining Consent in Children
The General Medical Council has provided guidelines for obtaining consent in children. According to these guidelines, young people who are 16 years or older can be treated as adults and are presumed to have the capacity to make decisions. However, for children under the age of 16, their ability to understand what is involved determines whether they have the capacity to decide. If a competent child refuses treatment, a person with parental responsibility or the court may authorize investigation or treatment that is in the child’s best interests.
When it comes to providing contraceptives to patients under 16 years of age, the Fraser Guidelines must be followed. These guidelines state that the young person must understand the professional’s advice, cannot be persuaded to inform their parents, is likely to begin or continue having sexual intercourse with or without contraceptive treatment, and will suffer physical or mental health consequences without contraceptive treatment. Additionally, the young person’s best interests require them to receive contraceptive advice or treatment with or without parental consent.
Some doctors use the term Fraser competency when referring to contraception and Gillick competency when referring to general issues of consent in children. However, rumors that Victoria Gillick removed her permission to use her name or applied copyright have been debunked. It is important to note that in Scotland, those with parental responsibility cannot authorize procedures that a competent child has refused.

A concerned mother brings her 4-year-old child to the Emergency Department with a ‘barking cough’. The child has been experiencing ‘noisy breathing’ and a fever for the past 48 hours. The child is eating and drinking, but not as much as usual. The child is urinating regularly and has no significant medical history. Upon examination, the child is alert, well, and smiling. The child is clearly suffering from a cold. There is no stridor, and vital signs are normal. The chest is clear, without signs of recession. The diagnosis is croup.
What is the most appropriate course of action?Your Answer: Give a single dose of dexamethasone orally, and discharge home with clear advice on the signs of worsening croup
Explanation:Croup is a viral illness that affects young children, causing a sudden-onset barking cough and upper airway inflammation. Mild cases can be treated with a single dose of oral dexamethasone, while moderate to severe cases require admission and nebulised adrenaline. This child has mild croup and should be given a single dose of oral dexamethasone before being discharged home with clear instructions on when to seek further medical attention. If the child develops any signs of respiratory distress, they should be taken to the Emergency Department immediately.

A 14-year-old high school student comes to your office with symptoms of depression. During the consultation, she reveals that she has been bullied for having sex with an 18-year-old boy in the same school. The sexual encounter was consensual and occurred only once, without the influence of drugs or alcohol.
What is the best immediate step to take?Your Answer: You must ask the girl to discuss it with the police because of her age
Correct Answer: You should disclose that this girl has been sexually active to the relevant authority
Explanation:When it comes to sexual issues involving young people, the topics of consent and confidentiality can be challenging. However, in this particular case, there is no ambiguity. Legally, individuals under the age of 13 are incapable of giving consent for sexual activity. Therefore, it is typically necessary to disclose this information. If there is a decision to withhold this information, it should be discussed with a designated doctor for child protection and documented appropriately. This is an uncommon occurrence. As the patient is under 13, she is unable to provide consent for sexual activity. While it may be necessary to discuss the situation with the patient’s mother, this is not the most urgent responsibility. The primary duty is to report the incident to the appropriate authority, and it cannot be left in the hands of the patient.

A father brings his 9-month-old to the pediatrician with concerns about a rash. The infant has been experiencing a fever and cold symptoms for a few days, and the rash appeared last night. It's worth noting that the baby started daycare two weeks ago. During the examination, the child is alert and responsive with good muscle tone. The baby has no fever, and all vital signs are normal. There is some nasal congestion, and a papular rash is present on the trunk, which disappears when pressed. What is the most probable cause of the rash?
Your Answer: Scarlet fever
Correct Answer: Roseola infantum
Explanation:Understanding Roseola Infantum
Roseola infantum, also known as exanthem subitum or sixth disease, is a common illness that affects infants and is caused by the human herpes virus 6 (HHV6). This disease has an incubation period of 5-15 days and is typically seen in children aged 6 months to 2 years. The most common symptoms of roseola infantum include a high fever that lasts for a few days, followed by a maculopapular rash. Other symptoms may include Nagayama spots, which are papular enanthems on the uvula and soft palate, as well as cough and diarrhea.
In some cases, febrile convulsions may occur in around 10-15% of children with roseola infantum. While this can be concerning for parents, it is important to note that this is a common occurrence and typically resolves on its own. Additionally, HHV6 infection can lead to other possible consequences such as aseptic meningitis and hepatitis.
It is important to note that school exclusion is not necessary for children with roseola infantum. While this illness can be uncomfortable for infants, it is typically not serious and resolves on its own within a few days.

A 4-week-old infant boy born at 37 weeks gestation by caesarian section is presented to his pediatrician for a routine check-up. The pediatrician observes that the neonate's urethral meatus is situated on the ventral aspect of the penile shaft, instead of the distal glans penis. What other congenital anomaly is this neonate more likely to have?
Your Answer: Posterior urethral valve
Correct Answer: Cryptorchidism
Explanation:Hypospadias is often accompanied by cryptorchidism in neonates, indicating a potential issue with embryological urogenital migration that may be linked to endocrine disruptions during pregnancy, such as low serum androgens. Imperforate anus, obstructive uropathy with a patent urachus, and posterior urethral valve are not associated with hypospadias and would present with different symptoms or complications.
Understanding Hypospadias: A Congenital Abnormality of the Penis
Hypospadias is a condition that affects approximately 3 out of 1,000 male infants. It is a congenital abnormality of the penis that is usually identified during the newborn baby check. However, if missed, parents may notice an abnormal urine stream. This condition is characterized by a ventral urethral meatus, a hooded prepuce, and chordee in more severe forms. The urethral meatus may open more proximally in the more severe variants, but 75% of the openings are distally located. There appears to be a significant genetic element, with further male children having a risk of around 5-15%.
Hypospadias most commonly occurs as an isolated disorder, but it can also be associated with other conditions such as cryptorchidism (present in 10%) and inguinal hernia. Once hypospadias has been identified, infants should be referred to specialist services. Corrective surgery is typically performed when the child is around 12 months of age. It is essential that the child is not circumcised prior to the surgery as the foreskin may be used in the corrective procedure. In boys with very distal disease, no treatment may be needed. Understanding hypospadias is important for parents and healthcare providers to ensure proper management and treatment of this condition.

A 16-year-old known type 1 diabetic presents with vomiting, abdominal pain, and drowsiness. During the examination, you detect a distinct smell of pear drops on her breath. Despite the severity of her condition, she insists on leaving to attend a friend's birthday party. After discussing the potential consequences of leaving, she appears to comprehend the risks and can articulate her decision. However, her parents believe she should remain for treatment. What course of action should you take?
Your Answer: Admit the patient for treatment, seeking legal advice if she continues to refuse treatment
Explanation:This person is below the age of 16 but is considered to have the ability to make decisions. As a result, they have the right to consent to treatment without the need for parental approval. However, if they choose to decline treatment, their best interests must be taken into account. In this case, the patient is suffering from diabetic ketoacidosis, and leaving without treatment would likely result in death. Therefore, it would be reasonable to conclude that it is in their best interests to receive treatment.
According to the General Medical Council’s ethical guidelines, parents cannot override the competent consent of a young person when it comes to treatment that is deemed to be in their best interests. However, if a child lacks the capacity to consent, parental consent can be relied upon. In Scotland, parents are unable to authorize treatment that a competent young person has refused. In England, Wales, and Northern Ireland, the laws regarding parents overriding a young person’s competent refusal are complex.
When a young person refuses treatment, the harm to their rights must be carefully weighed against the benefits of treatment to make decisions that are in their best interests. This is outlined in paragraphs 30-33 of the GMC’s ethical guidance for individuals aged 0-18 years.
Understanding Consent in Children
The issue of consent in children can be complex and confusing. However, there are some general guidelines to follow. If a patient is under 16 years old, they may be able to consent to treatment if they are deemed competent. This is determined by the Fraser guidelines, which were previously known as Gillick competence. However, even if a child is competent, they cannot refuse treatment that is deemed to be in their best interest.
For patients between the ages of 16 and 18, it is generally assumed that they are competent to give consent to treatment. Patients who are 18 years or older can consent to or refuse treatment.
When it comes to providing contraceptives to patients under 16 years old, the Fraser Guidelines outline specific requirements that must be met. These include ensuring that the young person understands the advice given by the healthcare professional, cannot be persuaded to inform their parents, is likely to engage in sexual activity with or without treatment, and will suffer physical or mental health consequences without treatment. Ultimately, the young person’s best interests must be taken into account when deciding whether to provide contraceptive advice or treatment, with or without parental consent.
In summary, understanding consent in children requires careful consideration of age, competence, and best interests. The Fraser Guidelines provide a useful framework for healthcare professionals to follow when providing treatment and advice to young patients.

Which one of the following conditions is not associated with obesity in adolescents?
Your Answer: Down's syndrome
Correct Answer: Growth hormone excess
Explanation:Understanding Obesity in Children
Childhood obesity is a complex issue that requires careful assessment and management. Unlike adults, defining obesity in children is more challenging as body mass index (BMI) varies with age. To accurately assess BMI, percentile charts are needed. According to recent guidelines by the National Institute for Health and Care Excellence (NICE), the UK 1990 BMI charts should be used to provide age- and gender-specific information.
NICE recommends tailored clinical intervention if BMI is at the 91st centile or above. If BMI is at the 98th centile or above, assessing for comorbidities is necessary. Lifestyle factors are the most common cause of obesity in childhood. However, other factors such as growth hormone deficiency, hypothyroidism, Down’s syndrome, Cushing’s syndrome, and Prader-Willi syndrome can also contribute to obesity in children.
Obesity in children can lead to various consequences, including orthopaedic problems such as slipped upper femoral epiphysis and Blount’s disease, musculoskeletal pains, psychological consequences like poor self-esteem and bullying, sleep apnoea, and benign intracranial hypertension. Moreover, obesity in childhood can increase the risk of developing type 2 diabetes mellitus, hypertension, and ischaemic heart disease in the long run. Therefore, it is crucial to identify and manage obesity in children to prevent these adverse outcomes.

A 6-day-old infant has been experiencing noisy breathing since birth. A perceptive resident physician identifies that the sound occurs during inhalation. What is the primary reason for stridor in a newborn?
Your Answer: Asthma
Correct Answer: Laryngomalacia
Explanation:1 – Children between 6 months and 3 years old are typically affected by croup.
2 – Stridor is a common symptom of Epiglottitis in children aged 2-4 years, although the introduction of the H. influenzae vaccine has almost eliminated this condition.
4 – Bronchiolitis often affects individuals between 3 and 6 months old.
5 – No information provided.Stridor in Children: Causes and Symptoms
Stridor is a high-pitched, wheezing sound that occurs during breathing and is commonly seen in children. There are several causes of stridor in children, including croup, acute epiglottitis, inhaled foreign body, and laryngomalacia. Croup is a viral infection that affects the upper respiratory tract and is characterized by stridor, barking cough, fever, and coryzal symptoms. Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B, which can lead to airway obstruction. Inhaled foreign body can cause sudden onset of coughing, choking, vomiting, and stridor, depending on the site of impaction. Laryngomalacia is a congenital abnormality of the larynx that typically presents at 4 weeks of age with stridor.
It is important to recognize the symptoms of stridor in children and seek prompt medical attention, especially if the child appears unwell or toxic. Treatment may include medications, such as corticosteroids or nebulized epinephrine, or in severe cases, intubation or tracheostomy. Prevention measures, such as vaccination against Haemophilus influenzae type B, can also help reduce the incidence of acute epiglottitis. Overall, early recognition and management of stridor in children can help prevent complications and improve outcomes.

A 9-month-old girl is brought to their GP due to family concerns over the child's development. They were born at term via vaginal delivery, without complications. The child is otherwise well, without past medical history.
What developmental milestone would be most anticipated in this child?Your Answer: Pass objects from one hand to another
Explanation:A 6-month-old boy was brought to the GP by his family who were concerned about his development. The GP tested his developmental milestones and found that he was able to hold objects with palmar grasp and pass objects from one hand to another. However, the child was not yet able to build a tower of 2 bricks, have a good pincer grip, or show a hand preference, which are expected milestones for older children. The GP reassured the family that the child’s development was within the normal range for his age.
Developmental Milestones for Fine Motor and Vision Skills
Fine motor and vision skills are important developmental milestones for infants and young children. These skills are crucial for their physical and cognitive development. The following tables provide a summary of the major milestones for fine motor and vision skills.
At three months, infants can reach for objects and hold a rattle briefly if given to their hand. They are visually alert, particularly to human faces, and can fix and follow objects up to 180 degrees. By six months, they can hold objects in a palmar grasp and pass them from one hand to another. They are visually insatiable, looking around in every direction.
At nine months, infants can point with their finger and demonstrate an early pincer grip. By 12 months, they have developed a good pincer grip and can bang toys together and stack bricks.
As children grow older, their fine motor skills continue to develop. By 15 months, they can build a tower of two blocks, and by 18 months, they can build a tower of three blocks. By two years old, they can build a tower of six blocks, and by three years old, they can build a tower of nine blocks. They also begin to draw, starting with circular scribbles at 18 months and progressing to copying vertical lines at two years old, circles at three years old, crosses at four years old, and squares and triangles at five years old.
In addition to fine motor skills, children’s vision skills also develop over time. At 15 months, they can look at a book and pat the pages. By 18 months, they can turn several pages at a time, and by two years old, they can turn one page at a time.
It is important to note that hand preference before 12 months is abnormal and may indicate cerebral palsy. Overall, these developmental milestones for fine motor and vision skills are important indicators of a child’s growth and development.

A 16-year-old girl visits her doctor with primary amenorrhoea and cyclical abdominal pain. The patient has normal secondary sexual characteristics on examination.
What is the probable cause of her absence of menstrual periods?Your Answer: Normal physiological delay
Correct Answer: Imperforate hymen
Explanation:The patient is experiencing cyclical abdominal pain and amenorrhoea, indicating a pathological delay in menarche rather than a normal physiological delay. A specialist should assess the patient, as an imperforate hymen may be present, causing obstruction of menstrual blood outflow. An ultrasound scan can confirm the presence of haematocolpos, and initial treatment involves using oral contraceptives to suppress menses and analgesia to manage pain until surgical correction and drainage of collected blood occurs. Congenital uterine deformities are associated with pelvic pain, abnormal bleeding, recurrent miscarriages, and premature delivery. Hyperprolactinaemia and hypothyroidism are less likely causes, as the patient does not exhibit symptoms such as headaches, galactorrhoea, breast pain, fatigue, constipation, weight gain, cold intolerance, muscle weakness, depression, or altered mental function.

A 9-year-old girl presents with symptoms of left knee pain. The pain has been present on most occasions for the past four months and the pain typically lasts for several hours at a time. On examination; she walks with an antalgic gait and has apparent left leg shortening. What is the most likely diagnosis?
Your Answer: Transient synovitis of the hip
Correct Answer: Perthes Disease
Explanation:Hip pain in the 10-14 year age group can have various causes, some of which may also result in knee pain. The most common disorder is transient synovitis of the hip, but it usually does not persist for more than 3 months. An osteosarcoma typically does not cause limb shortening unless there is a pathological fracture. While a slipped upper femoral epiphysis can lead to a similar presentation, it usually occurs later and in patients with different characteristics.
Understanding Perthes’ Disease
Perthes’ disease is a degenerative condition that affects the hip joints of children, typically between the ages of 4-8 years. It is caused by a lack of blood supply to the femoral head, which leads to bone infarction and avascular necrosis. This condition is more common in boys, with around 10% of cases being bilateral. The symptoms of Perthes’ disease include hip pain, stiffness, reduced range of hip movement, and a limp. Early changes can be seen on an x-ray, such as widening of the joint space, while later changes include decreased femoral head size and flattening.
To diagnose Perthes’ disease, a plain x-ray is usually sufficient. However, if symptoms persist and the x-ray is normal, a technetium bone scan or magnetic resonance imaging may be necessary. If left untreated, Perthes’ disease can lead to complications such as osteoarthritis and premature fusion of the growth plates.
The severity of Perthes’ disease is classified using the Catterall staging system, which ranges from stage 1 (clinical and histological features only) to stage 4 (loss of acetabular integrity). Treatment options include keeping the femoral head within the acetabulum using a cast or braces, observation for children under 6 years old, and surgical management for older children with severe deformities. The prognosis for Perthes’ disease is generally good, with most cases resolving with conservative management. Early diagnosis is key to improving outcomes.

A 3-year-old boy is brought to see the pediatrician by his father. He was born at 34/40 weeks gestation. His father is worried about cerebral palsy, as he has heard that premature birth can cause developmental problems. The child has been meeting all his developmental milestones, but his father is still concerned. During the examination, the boy shows normal power, tone, and reflexes in all four limbs.
What developmental problem would indicate a diagnosis of cerebral palsy in this 3-year-old boy?Your Answer: Loss of attained developmental milestones
Correct Answer: Not walking by 18 months old (corrected for prematurity)
Explanation:Developmental Milestones and Red Flags in Children: A Guide for Parents and Caregivers
As children grow and develop, they reach certain milestones that indicate their progress in various areas such as motor skills, social skills, and language development. However, if a child is not meeting these milestones within a certain timeframe, it may be a cause for concern and require further investigation. Here are some red flags to look out for:
– Not walking by 18 months old (corrected for prematurity): This may be a sign of cerebral palsy or other developmental problems including muscular dystrophy. Other areas of development should also be assessed.
– Hand preference at 18 months old: It is abnormal for a child to develop hand dominance before the age of 12 months old. This could be a sign of cerebral palsy or an injury causing an occult fracture or neuropathy.
– Loss of attained developmental milestones: While cerebral palsy is a non-progressive condition, delays in achieving milestones may be a sign of prenatal infections, birth trauma, hypoxic brain injury, or meningitis in the neonatal period.
– Not able to balance on one leg by the age of two years: This may be a sign of cerebral palsy or Duchenne muscular dystrophy.
– Not sitting up by six months old (corrected for prematurity): If a baby is unable to sit unsupported by the age of eight months, corrected for prematurity, further investigations should be done.It is important to remember that every child develops at their own pace, but if you have concerns about your child’s development, it is always best to seek advice from a healthcare professional. Early intervention and support can make a significant difference in a child’s development and future outcomes.

A mother brings her 18-day old baby to the emergency department with visible jaundice and distress. The baby has been feeding poorly since yesterday. Upon examination, hepatomegaly and splenomegaly are observed. The newborn jaundice screen shows no infection, normal thyroid function tests, raised conjugated bilirubin, liver transaminases, and bile acids. Reducing substances are absent in the urine. What is the initial management option for the most probable diagnosis?
Your Answer: Frequent monitoring
Correct Answer: Surgical intervention
Explanation:Biliary atresia is diagnosed when a newborn presents with prolonged jaundice, hepatomegaly, splenomegaly, abnormal growth, and cardiac murmurs. Surgery is the preferred treatment, specifically a hepatoportoenterostomy (HPE), also known as Kasai portoenterostomy. This procedure removes the blocked bile ducts and replaces them with a segment of the small intestine, restoring bile flow from the liver to the proximal small bowel. Ursodeoxycholic acid may be given as an adjuvant after surgery to facilitate bile flow and protect the liver. However, it should not be given if the total bilirubin is >256.6 micromol/L (>15 mg/dL). Frequent monitoring is not sufficient, urgent action is required. Liver transplant is not the first-line treatment, but may be considered if HPE is unsuccessful or if there are signs of end-stage liver disease, progressive cholestasis, hepatocellular decompensation, or severe portal hypertension.
Understanding Biliary Atresia in Neonatal Children
Biliary atresia is a condition that affects the extrahepatic biliary system in neonatal children, resulting in an obstruction in the flow of bile. This condition is more common in females than males and occurs in 1 in every 10,000-15,000 live births. There are three types of biliary atresia, with type 3 being the most common. Patients typically present with jaundice, dark urine, pale stools, and abnormal growth.
To diagnose biliary atresia, doctors may perform various tests, including serum bilirubin, liver function tests, serum alpha 1-antitrypsin, sweat chloride test, and ultrasound of the biliary tree and liver. Surgical intervention is the only definitive treatment for biliary atresia, and medical intervention includes antibiotic coverage and bile acid enhancers following surgery.
Complications of biliary atresia include unsuccessful anastomosis formation, progressive liver disease, cirrhosis, and eventual hepatocellular carcinoma. However, the prognosis is good if surgery is successful. In cases where surgery fails, liver transplantation may be required in the first two years of life. Overall, understanding biliary atresia is crucial for early diagnosis and effective management in neonatal children.

A murmur is incidentally discovered by a GP in a 9-year-old girl. The murmur is described as a 'continuous blowing noise' heard below both clavicles. What type of murmur is most likely to be diagnosed?
Your Answer: Pulmonary flow murmur
Correct Answer: Venous hum
Explanation:A venous hum is a harmless murmur commonly found in children. It is characterized by a constant blowing sound that can be heard beneath the collarbones. In contrast, a Still’s murmur is also benign but produces a low-pitched noise on the lower left side of the sternum. A pulmonary flow murmur is another harmless murmur, but it is heard on the upper left side of the sternum. The remaining murmurs are considered pathological.
Innocent murmurs are common in children and are usually harmless. There are different types of innocent murmurs, including ejection murmurs, venous hums, and Still’s murmur. Ejection murmurs are caused by turbulent blood flow at the outflow tract of the heart, while venous hums are due to turbulent blood flow in the great veins returning to the heart. Still’s murmur is a low-pitched sound heard at the lower left sternal edge.
An innocent ejection murmur is characterized by a soft-blowing murmur in the pulmonary area or a short buzzing murmur in the aortic area. It may vary with posture and is localized without radiation. There is no diastolic component, no thrill, and no added sounds such as clicks. The child is usually asymptomatic, and there are no other abnormalities.
Overall, innocent murmurs are not a cause for concern and do not require treatment. However, if a child has symptoms such as chest pain, shortness of breath, or fainting, further evaluation may be necessary to rule out any underlying heart conditions.

A 29-year-old primiparous woman who is 20 weeks pregnant comes in for a consultation after her foetal anomaly scan revealed polyhydramnios and a midline sac containing bowel. She has no significant medical history and is not taking any regular medications. She had planned for a home birth and is now concerned about how this condition will affect her delivery.
What is the best course of action for managing this condition?Your Answer: Plan for delivery on the ward
Correct Answer: Schedule an elective caesarean section
Explanation:If a foetus is diagnosed with exomphalos before birth, it is recommended to schedule and perform a caesarean section at term to reduce the risk of sac rupture, infection, and atresia. While a ward delivery provides access to theatres, specific surgical planning is necessary to minimize complications. Instrumental delivery in theatre does not decrease the risk of sac rupture. It is important to explain to the mother why hospital delivery is necessary and the risks associated with a home birth. Induction of labour at 37 weeks is not advisable as it increases the risk of complications during vaginal delivery.
Gastroschisis and exomphalos are both types of congenital visceral malformations. Gastroschisis refers to a defect in the anterior abdominal wall located just beside the umbilical cord. In contrast, exomphalos, also known as omphalocoele, involves the protrusion of abdominal contents through the anterior abdominal wall, which are covered by an amniotic sac formed by amniotic membrane and peritoneum.
When it comes to managing gastroschisis, vaginal delivery may be attempted, but newborns should be taken to the operating theatre as soon as possible after delivery, ideally within four hours. As for exomphalos, a caesarean section is recommended to reduce the risk of sac rupture. In cases where primary closure is difficult due to lack of space or high intra-abdominal pressure, a staged repair may be undertaken. This involves allowing the sac to granulate and epithelialise over several weeks or months, forming a shell. As the infant grows, the sac contents will eventually fit within the abdominal cavity, at which point the shell can be removed and the abdomen closed.
Overall, both gastroschisis and exomphalos require careful management to ensure the best possible outcome for the newborn. By understanding the differences between these two conditions and the appropriate steps to take, healthcare professionals can provide effective care and support to both the infant and their family.

A 9-year-old girl comes to the GP with her father. She has been complaining of nausea for the past few days along with dysuria and increased frequency. Her father is worried that she might have a urinary tract infection. Upon examination, the girl seems healthy and her vital signs are stable. There are no notable findings during abdominal examination. A clean catch sample is collected and shows positive results for leucocytes and nitrites. What should be the next course of action in managing this case?
Your Answer: Reassure illness should resolve within 72 hours
Correct Answer: 3 day course antibiotics as per local policy
Explanation:The scenario describes a child showing symptoms of a lower urinary tract infection, which is common in girls of her age. To confirm the diagnosis, a clean catch urine sample should be obtained for testing. However, given the child’s positive test results for leucocytes and nitrites, along with her history of dysuria and frequency, treatment should be initiated immediately. As per local guidelines, a 3-day course of antibiotics is recommended for children of her age with lower urinary tract infections. The child’s mother should be advised to return if the symptoms persist beyond 48 hours. It’s important to note that a 10-day course of co-amoxiclav is only prescribed if the infection is in the upper urinary tract.
Urinary tract infections (UTI) are more common in boys until 3 months of age, after which the incidence is substantially higher in girls. Presentation in childhood depends on age, with infants showing poor feeding, vomiting, and irritability, younger children showing abdominal pain, fever, and dysuria, and older children showing dysuria, frequency, and haematuria. NICE guidelines recommend checking urine samples in children with symptoms or signs suggestive of a UTI, unexplained fever of 38°C or higher, or an alternative site of infection but who remain unwell. Urine collection should be done through clean catch or urine collection pads, and invasive methods should only be used if non-invasive methods are not possible. Management includes referral to a paediatrician for infants less than 3 months old, admission to hospital for children aged more than 3 months old with an upper UTI, and oral antibiotics for 3-10 days for children aged more than 3 months old with a lower UTI. Antibiotic prophylaxis is not given after the first UTI but should be considered with recurrent UTIs.

You are a junior doctor in paediatrica and have been asked to perform a newborn exam. Which statement is true regarding the Barlow and Ortolani manoeuvres?
Your Answer: Parents can be reassured that a negative test excludes all hip problems in their child
Correct Answer: It relocates a dislocation of the hip joint if this has been elicited during the Barlow manoeuvre
Explanation:Understanding the Barlow and Ortolani Manoeuvres for Hip Dislocation Screening
Hip dislocation is a common problem in infants, and early detection is crucial for successful treatment. Two screening tests commonly used are the Barlow and Ortolani manoeuvres. The Barlow manoeuvre involves adducting the hip while applying pressure on the knee, while the Ortolani manoeuvre flexes the hips and knees to 90 degrees, with pressure applied to the greater trochanters and thumbs to abduct the legs. A positive test confirms hip dislocation, and further investigation is necessary if risk factors are present, such as breech delivery or a family history of hip problems. However, a negative test does not exclude all hip problems, and parents should seek medical advice if they notice any asymmetry or walking difficulties in their child.

A 4-month-old boy is brought to the clinic by his parents as they are concerned about a possible heart condition. The baby was born full-term and has had no major health issues except for a mild cold. After examining the child, the consultant paediatrician suspects the presence of a patent ductus arteriosus (PDA).
What is a clinical feature that would indicate the presence of a PDA in this infant?Your Answer: Congenital toxoplasmosis
Correct Answer: Wide pulse pressure
Explanation:Patent ductus arteriosus (PDA) is a condition where the ductus arteriosus fails to close, causing a left-to-right shunt of blood from the aorta to the pulmonary artery. This can lead to a spectrum of clinical effects, including a continuous murmur, increased pressure in diastole, and widened pulse pressures. Larger PDAs can cause dilation and cardiac failure, and may be associated with prematurity, female infants, congenital rubella syndrome, and Down’s syndrome. PDAs should be closed if detected to prevent complications such as pulmonary hypertension and right heart failure.

A 15-year-old girl comes to your clinic with concerns about not having started her menstrual cycle yet. As her physician, you decide to investigate the reason for this delay. During the physical examination, you observe that she has low set ears and a short stature. What type of murmur are you likely to detect upon auscultation?
Your Answer: Late diastolic murmur
Correct Answer: Ejection systolic murmur
Explanation:An ejection systolic murmur is commonly heard in individuals with Turner’s syndrome, which is often caused by a bicuspid aortic valve. Therefore, this is the most probable answer. Aortic or pulmonary regurgitation can cause early diastolic murmurs, while AV stenosis is associated with late diastolic murmurs. Late systolic murmurs are linked to mitral regurgitation, and aortic stenosis is associated with a pansystolic murmur. Given the patient’s symptoms and characteristics, it is essential to consider heart defects or murmurs that are commonly associated with Turner’s syndrome.
Understanding Turner’s Syndrome
Turner’s syndrome is a genetic disorder that affects approximately 1 in 2,500 females. It is caused by the absence of one sex chromosome (X) or a deletion of the short arm of one of the X chromosomes. This condition is denoted as 45,XO or 45,X.
The features of Turner’s syndrome include short stature, a shield chest with widely spaced nipples, a webbed neck, a bicuspid aortic valve (15%), coarctation of the aorta (5-10%), primary amenorrhea, cystic hygroma (often diagnosed prenatally), a high-arched palate, a short fourth metacarpal, multiple pigmented naevi, lymphoedema in neonates (especially feet), and elevated gonadotrophin levels. Hypothyroidism is much more common in Turner’s syndrome, and there is also an increased incidence of autoimmune disease (especially autoimmune thyroiditis) and Crohn’s disease.
In summary, Turner’s syndrome is a chromosomal disorder that affects females and can cause a range of physical features and health issues. Early diagnosis and management can help individuals with Turner’s syndrome lead healthy and fulfilling lives.

A 35-year-old man has been experiencing muscle weakness and cramps, and after extensive investigation, it has been determined that he has a rare form of myopathy. His family history reveals that his mother, maternal grandmother, brother, maternal aunt, and her two sons are all affected by the same condition. Interestingly, his maternal uncle has the disease, but none of his children do. There is no evidence of the disease on the paternal side, and his wife has no family history of the disorder. What is the likelihood that his biological children will inherit the myopathy from him?
Your Answer: 100%
Correct Answer: 0%
Explanation:Mitochondrial Diseases: Inheritance and Histology
Mitochondrial diseases are caused by mutations in the small amount of double-stranded DNA present in the mitochondria. This DNA encodes protein components of the respiratory chain and some special types of RNA. Mitochondrial inheritance has unique characteristics, including inheritance only via the maternal line and none of the children of an affected male inheriting the disease. However, all of the children of an affected female will inherit the disease. These diseases generally encode rare neurological diseases and have a poor genotype-phenotype correlation due to heteroplasmy, where different mitochondrial populations exist within a tissue or cell.
Histologically, muscle biopsy shows red, ragged fibers due to an increased number of mitochondria. Some examples of mitochondrial diseases include Leber’s optic atrophy, MELAS syndrome (mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes), MERRF syndrome (myoclonus epilepsy with ragged-red fibers), Kearns-Sayre syndrome (onset in patients < 20 years old, external ophthalmoplegia, retinitis pigmentosa, and ptosis may be seen), and sensorineural hearing loss.

A 4-year-old girl comes to the doctor's office complaining of nightly coughing fits over the past 2 weeks. She has an inspiratory whoop and noisy breathing, but no signs of cyanosis or other abnormalities during the physical exam. The doctor diagnoses her with whooping cough. What is the most appropriate initial treatment for this patient?
Your Answer: Clarithromycin
Explanation:According to NICE guidelines, if a patient has developed a cough within the last 21 days and does not require hospitalization, macrolide antibiotics such as azithromycin or clarithromycin should be prescribed for children over 1 month old and non-pregnant adults. In this case, the patient does not meet the criteria for hospitalization due to their age, breathing difficulties, or complications. Along with antibiotics, patients should be advised to rest, stay hydrated, and use pain relievers like paracetamol or ibuprofen for symptom relief.
Whooping Cough: Causes, Symptoms, Diagnosis, and Management
Whooping cough, also known as pertussis, is a contagious disease caused by the bacterium Bordetella pertussis. It is commonly found in children, with around 1,000 cases reported annually in the UK. The disease is characterized by a persistent cough that can last up to 100 days, hence the name cough of 100 days.
Infants are particularly vulnerable to whooping cough, which is why routine immunization is recommended at 2, 3, 4 months, and 3-5 years. However, neither infection nor immunization provides lifelong protection, and adolescents and adults may still develop the disease.
Whooping cough has three phases: the catarrhal phase, the paroxysmal phase, and the convalescent phase. The catarrhal phase lasts around 1-2 weeks and presents symptoms similar to a viral upper respiratory tract infection. The paroxysmal phase is characterized by a severe cough that worsens at night and after feeding, and may be accompanied by vomiting and central cyanosis. The convalescent phase is when the cough subsides over weeks to months.
To diagnose whooping cough, a person must have an acute cough that has lasted for 14 days or more without another apparent cause, and have one or more of the following features: paroxysmal cough, inspiratory whoop, post-tussive vomiting, or undiagnosed apnoeic attacks in young infants. A nasal swab culture for Bordetella pertussis is used to confirm the diagnosis, although PCR and serology are increasingly used.
Infants under 6 months with suspected pertussis should be admitted, and in the UK, pertussis is a notifiable disease. An oral macrolide, such as clarithromycin, azithromycin, or erythromycin, is indicated if the onset of the cough is within the previous 21 days to eradicate the organism and reduce the spread. Household contacts should be offered antibiotic prophylaxis, although antibiotic therapy has not been shown to alter the course of the illness. School exclusion is recommended for 48 hours after commencing antibiotics or 21 days from onset of symptoms if no antibiotics are given.
Complications of whooping cough include subconjunctival haemorrhage, pneumonia, bronchiectasis, and

A 2-week-old girl has her hearing checked through the Newborn Hearing Screening program. She had a normal delivery at 40 weeks and was discharged home with her parents. The hearing screening was abnormal and a follow-up test is required to confirm. What is the follow-up test in this scenario?
Your Answer: Newborn otoacoustic emission test
Correct Answer: Auditory brainstem response test
Explanation:When a newborn baby’s hearing test at birth shows an abnormal result, they are offered an auditory brainstem response test as a follow-up. This test involves placing electrodes on the baby’s scalp to measure their auditory evoked potentials in response to sounds. If there is no response, it may indicate reduced hearing ability.
It is not appropriate to use a distraction test on a newborn as they are not yet developed enough for this type of testing. This test is typically used for toddlers aged 6-9 months and requires two staff members. The test involves producing sounds to the right or left of the baby, out of their field of view, and assessing the loudness required for them to react.
Newborn otoacoustic emission testing is the initial screening assessment for hearing in newborns. However, this is only a screening test and further investigations are required to confirm any hearing loss. The test works by generating a click sound through an earpiece and measuring for the presence of a soft echo, which indicates a healthy cochlea.
Pure tone audiometry is not an appropriate second-line hearing investigation for newborns. This test requires the participant to indicate when they hear specific sounds and is typically used in school-aged children. Therefore, it is not useful for newborns.
Hearing Tests for Children
Hearing tests are important for children to ensure that they are developing normally. There are several tests that may be performed on children of different ages. For newborns, an otoacoustic emission test is typically done as part of the Newborn Hearing Screening Programme. This test involves playing a computer-generated click through a small earpiece and checking for the presence of a soft echo, which indicates a healthy cochlea. If the results of this test are abnormal, an Auditory Brainstem Response test may be done.
For infants between 6-9 months, a Distraction test may be performed by a health visitor with the help of two trained staff members. For children between 18 months to 2.5 years, a Recognition of familiar objects test may be used, which involves using familiar objects like a teddy or cup and asking the child simple questions like where is the teddy? For children over 2.5 years, Performance testing and Speech discrimination tests may be used, such as the Kendall Toy test or McCormick Toy Test. Pure tone audiometry is typically done at school entry in most areas of the UK for children over 3 years old.
In addition to these tests, there is also a questionnaire for parents in the Personal Child Health Records called Can your baby hear you? It is important for parents to be aware of these tests and to have their child’s hearing checked regularly to ensure proper development.

A 10-year-old girl visits her GP complaining of stiffness, swelling, and pain in both knees. During the examination, the doctor observes a salmon-pink rash on her legs. What is the probable diagnosis?
Your Answer: Measles
Correct Answer: Juvenile idiopathic arthritis
Explanation:Juvenile idiopathic arthritis, also known as Still’s disease, is identified by the presence of a distinct salmon-pink rash along with joint pain. While joint pain may also be present in Henoch-Schonlein purpura, the rash in this condition is palpable and purpuric. Meningitis, on the other hand, is characterized by a non-blanching purpuric rash but does not cause joint pain.
Understanding Systemic Onset Juvenile Idiopathic Arthritis
Juvenile idiopathic arthritis (JIA) is a condition that affects individuals under the age of 16 and lasts for more than six weeks. It is also known as juvenile chronic arthritis. Systemic onset JIA, also referred to as Still’s disease, is a type of JIA that presents with several symptoms. These symptoms include pyrexia, a salmon-pink rash, lymphadenopathy, arthritis, uveitis, anorexia, and weight loss.
When investigating systemic onset JIA, doctors may find that the antinuclear antibody (ANA) is positive, especially in oligoarticular JIA. However, the rheumatoid factor is usually negative. It is important to note that systemic onset JIA can be challenging to diagnose, as its symptoms can mimic other conditions.

A 3-year-old girl with a 2-day history of coughing is brought in by her father. The cough is non-productive in nature. On examination, she has no accessory muscle usage and is afebrile. On auscultation, she is noted to have a left-sided wheeze.
What is the most likely cause of this?Your Answer: Inhaled foreign body
Explanation:Pediatric Wheezing: Causes and Characteristics
Pediatric wheezing can be caused by various conditions, each with its own unique characteristics. Unilateral wheeze in a child under three years old is often associated with inhalation of a foreign body, which can partially or completely obstruct the airway. Bronchiolitis, typically caused by respiratory syncytial virus, initially presents as an upper respiratory tract infection and progresses to a lower respiratory tract infection with bilateral wheeze, cough, and difficulty breathing. Pneumonia may also cause wheezing, but is typically accompanied by systemic symptoms such as fever and crepitations on auscultation. Asthma, a common cause of pediatric wheezing, is characterized by bilateral expiratory wheezing due to premature bronchiole collapse. Croup, caused by a parainfluenza virus, presents with a barking cough, stridor, and respiratory distress, and is treated with dexamethasone.

During the examination, a rough-textured maculopapular rash is found to be widespread. Her tongue is swollen, red, and covered with white papillae, and her tonsils are erythematosus. All other system examinations are normal.
What is the most likely diagnosis based on these findings?Your Answer: Roseola infantum
Correct Answer: Scarlet fever
Explanation:Scarlet fever is a condition caused by erythrogenic toxins produced by Group A haemolytic streptococci, usually Streptococcus pyogenes. It is more prevalent in children aged 2-6 years, with the highest incidence at 4 years. The disease spreads through respiratory droplets or direct contact with nose and throat discharges, especially during sneezing and coughing. The incubation period is 2-4 days, and symptoms include fever, malaise, headache, nausea/vomiting, sore throat, ‘strawberry’ tongue, and a rash that appears first on the torso and spares the palms and soles. The rash has a rough ‘sandpaper’ texture and desquamation occurs later in the course of the illness, particularly around the fingers and toes.
To diagnose scarlet fever, a throat swab is usually taken, but antibiotic treatment should be initiated immediately, rather than waiting for the results. Management involves administering oral penicillin V for ten days, while patients with a penicillin allergy should be given azithromycin. Children can return to school 24 hours after commencing antibiotics, and scarlet fever is a notifiable disease. Although usually a mild illness, scarlet fever may be complicated by otitis media, rheumatic fever, acute glomerulonephritis, or rare invasive complications such as bacteraemia, meningitis, or necrotizing fasciitis, which may present acutely with life-threatening illness.

What is the typical distribution of atopic eczema in a 12-month-old child?
Your Answer: Scalp and arms
Correct Answer: Face and trunk
Explanation:Eczema in Children: Symptoms and Management
Eczema is a common skin condition that affects around 15-20% of children and is becoming more prevalent. It usually appears before the age of 2 and clears up in around 50% of children by the age of 5 and in 75% of children by the age of 10. The symptoms of eczema include an itchy, red rash that can worsen with repeated scratching. In infants, the face and trunk are often affected, while in younger children, it typically occurs on the extensor surfaces. In older children, the rash is more commonly seen on the flexor surfaces and in the creases of the face and neck.
To manage eczema in children, it is important to avoid irritants and use simple emollients. Large quantities of emollients should be prescribed, roughly in a ratio of 10:1 with topical steroids. If a topical steroid is also being used, the emollient should be applied first, followed by waiting at least 30 minutes before applying the topical steroid. Creams are absorbed into the skin faster than ointments, and emollients can become contaminated with bacteria, so fingers should not be inserted into pots. Many brands have pump dispensers to prevent contamination.
In severe cases, wet wrapping may be used, which involves applying large amounts of emollient (and sometimes topical steroids) under wet bandages. Oral ciclosporin may also be used in severe cases. Overall, managing eczema in children involves a combination of avoiding irritants, using emollients, and potentially using topical steroids or other medications in severe cases.

A 10-year-old boy is seen in the paediatric clinic for a follow-up appointment. His standing height is below the 0.4th centile, while his sitting height is on the 9th centile. These measurements have been consistent with their respective centiles for the past three years. What genetic diagnosis is most probable for this boy?
Your Answer: Fragile X syndrome
Correct Answer: Achondroplasia
Explanation:Achondroplasia and Other Causes of Short Stature
Achondroplasia is a genetic condition that affects bone growth, resulting in disproportionately short limbs and a greater sitting height compared to standing height. This is because the condition impairs the growth of cartilaginous bone, leading to much shorter arms and legs than the spine. Measuring sitting height can help estimate axial skeleton growth compared to standing height, which includes the limbs.
Other causes of short stature include Down’s syndrome and Noonan’s syndrome, which result in proportionate short stature and a similar standing and sitting centile. However, Fragile X syndrome and Klinefelter’s syndrome typically do not cause short stature. It is important to understand the underlying causes of short stature in order to provide appropriate medical care and support for individuals affected by these conditions.

What technique will be employed to test the child's hearing as part of the screening program?Your Answer: Otoacoustic emission test
Correct Answer: Pure tone audiometry
Explanation:The appropriate test for school entry hearing screening in most areas of the UK is pure tone audiometry. This test is suitable for individuals over the age of 3 and involves playing sounds at varying frequencies and volumes, with the patient indicating when they can no longer hear the sound. This test helps to identify the presence of hearing loss, the affected frequencies, and the severity of the condition.
The auditory brainstem response test, distraction test, and otoacoustic emission test are not suitable for school entry hearing screening. The auditory brainstem response test is typically performed on newborns and infants with abnormal otoacoustic emission test results. The distraction test is used for children aged 6-9 months to assess their ability to hear and locate sounds. The otoacoustic emission test is part of the newborn hearing screening program and is used to determine the health of the cochlea.
Hearing Tests for Children
Hearing tests are important for children to ensure that they are developing normally. There are several tests that may be performed on children of different ages. For newborns, an otoacoustic emission test is typically done as part of the Newborn Hearing Screening Programme. This test involves playing a computer-generated click through a small earpiece and checking for the presence of a soft echo, which indicates a healthy cochlea. If the results of this test are abnormal, an Auditory Brainstem Response test may be done.
For infants between 6-9 months, a Distraction test may be performed by a health visitor with the help of two trained staff members. For children between 18 months to 2.5 years, a Recognition of familiar objects test may be used, which involves using familiar objects like a teddy or cup and asking the child simple questions like where is the teddy? For children over 2.5 years, Performance testing and Speech discrimination tests may be used, such as the Kendall Toy test or McCormick Toy Test. Pure tone audiometry is typically done at school entry in most areas of the UK for children over 3 years old.
In addition to these tests, there is also a questionnaire for parents in the Personal Child Health Records called Can your baby hear you? It is important for parents to be aware of these tests and to have their child’s hearing checked regularly to ensure proper development.

A 24-hour old baby is evaluated in the neonatal intensive care unit due to tremors in his limbs, as observed by his nurse. He is also experiencing poor feeding, increased irritability, and excessive drowsiness. The baby was delivered via emergency caesarean section at 34 weeks due to reduced foetal movements and foetal bradycardia. The mother had an otherwise healthy pregnancy, but was taking lamotrigine for epilepsy. During the examination, the baby appeared larger than expected for his prematurity and exhibited visible arm tremors. Based on these symptoms, which aspect of the baby's medical history is most likely responsible for his condition?
Your Answer: Delivery via emergency caesarean section
Correct Answer: Prematurity
Explanation:Prematurity is a significant risk factor for neonatal hypoglycaemia, which is characterized by autonomic symptoms such as irritability and jitteriness, as well as neuroglycopenic symptoms like drowsiness and poor feeding. This is because preterm infants have not yet developed the same glycogen reserve as term infants. Admission to the neonatal intensive care unit, delivery via emergency caesarean section, formula feeding, and maternal lamotrigine use are not independent risk factors for neonatal hypoglycaemia. While caesarean section may result in transient hypoglycaemia, it is not typically symptomatic due to the lack of catecholamine release present during vaginal delivery. Terbutaline use, on the other hand, may increase the risk of hypoglycaemia.
Neonatal Hypoglycaemia: Causes, Symptoms, and Management
Neonatal hypoglycaemia is a common condition in newborn babies, especially in the first 24 hours of life. While there is no agreed definition, a blood glucose level of less than 2.6 mmol/L is often used as a guideline. Transient hypoglycaemia is normal and usually resolves on its own, but persistent or severe hypoglycaemia may be caused by various factors such as preterm birth, maternal diabetes mellitus, IUGR, hypothermia, neonatal sepsis, inborn errors of metabolism, nesidioblastosis, or Beckwith-Wiedemann syndrome.
Symptoms of neonatal hypoglycaemia can be autonomic, such as jitteriness, irritability, tachypnoea, and pallor, or neuroglycopenic, such as poor feeding/sucking, weak cry, drowsiness, hypotonia, and seizures. Other features may include apnoea and hypothermia. Management of neonatal hypoglycaemia depends on the severity of the condition and whether the newborn is symptomatic or not. Asymptomatic babies can be encouraged to feed normally and have their blood glucose monitored, while symptomatic or severely hypoglycaemic babies may need to be admitted to the neonatal unit and receive intravenous infusion of 10% dextrose.

A toddler with macrosomia has had a difficult delivery, owing to shoulder dystocia. The obstetrician pulled the child’s head downwards towards the floor to disengage the anterior shoulder from below the pubic bones. When the child is having a check-up prior to discharge, the paediatrician notes that the left upper limb is adducted and medially rotated, with extension at the elbow joint. When questioned, the mother admits that the child has not been moving it.
What is the most likely diagnosis?Your Answer: Erb–Duchenne palsy due to trauma to the upper trunk of the brachial plexus
Explanation:Differentiating Brachial Plexus Injuries: Causes and Symptoms
The brachial plexus is a network of nerves that originates from the spinal cord and supplies the upper limb. Trauma to this network can result in various types of injuries, each with its own set of symptoms. Here are some of the common types of brachial plexus injuries and their distinguishing features:
Erb-Duchenne Palsy: This injury occurs due to trauma to the upper trunk of the brachial plexus, typically during obstructed labor or delivery. The affected muscles include those supplied by the musculocutaneous, radial, and axillary nerves, resulting in adduction and medial rotation of the arm, wrist drop, and sensory loss along the posterolateral aspect of the limb.
Isolated Radial Nerve Injury: This type of injury is associated with paralysis of the wrist and digital extensors, as well as the triceps. However, medial rotation of the humerus is not affected.
Klumpke’s Palsy: This injury is caused by trauma to the lower trunk of the brachial plexus, often during difficult delivery or sudden upward stretching of the upper limb. It results in claw hand due to damage to T1, causing paralysis of the short muscles of the hand.
Isolated Axillary Nerve Injury: With this type of injury, the wrist extensors function normally.
Isolated Musculocutaneous Nerve Injury: This injury is not associated with wrist drop.
In summary, understanding the specific symptoms associated with each type of brachial plexus injury can aid in accurate diagnosis and treatment.

A 10-year-old foster parent brings in her 7-year-old foster child to the GP. He has been complaining of pain when going to the toilet. The foster mother explains that he often has pain when urinating and as a younger child often cried when passing urine. He has only recently developed pain while defecating, however, the foster mother is clearly concerned and consents to the GP examining the child.
What clinical findings are most likely to indicate child sexual abuse in a 7-year-old child who complains of pain when going to the toilet and has a history of crying while passing urine?Your Answer: Haemorrhoids and Candida infection
Correct Answer: Anal fissures and recurrent urinary tract infections
Explanation:Childhood sexual abuse may be indicated by the presence of anal fissures and recurrent UTIs in children.
Signs of childhood sexual abuse can include various symptoms such as pregnancy, sexually transmitted infections, sexually precocious behavior, anal fissure, bruising, reflex anal dilation, enuresis and encopresis, behavioral problems, self-harm, and recurrent symptoms such as headaches and abdominal pain. However, haemorrhoids and Candida infections are not specific clinical features that suggest a child may be at risk of sexual abuse.
Understanding Sexual Abuse in Children
Sexual abuse is a serious issue that affects many children, but unfortunately, adults often do not believe their allegations. Children with special educational needs are at a higher risk of being sexually abused. The abusers can be anyone, but statistics show that 30% of abusers are fathers, 15% are unrelated men, and 10% are older brothers.
There are several features that may be present in a sexually abused child, including pregnancy, sexually transmitted infections, recurrent UTIs, sexually precocious behavior, anal fissure, bruising, reflex anal dilation, enuresis and encopresis, behavioral problems, self-harm, and recurrent symptoms such as headaches and abdominal pain.
It is important to recognize these signs and take action to protect children from sexual abuse. By understanding the signs and symptoms, we can work towards preventing and addressing this issue.

A 6-year-old male is brought to the emergency department by his mother due to increasing lethargy over the past few days. The child has a temperature of 38.6ºC and appears more pale than usual. Upon physical examination, petechiae and bruising are noted on the lower extremities. The following blood results are obtained: Hb 94 g/L (135-180), Platelets 86 * 109/L (150 - 400), WBC 26 * 109/L (4.0 - 11.0), Neutrophils 1.0 * 109/L (2.0 - 7.0).
What is the most likely diagnosis?Your Answer: Beta thalassaemia
Correct Answer: Acute lymphoblastic leukaemia
Explanation:The most common childhood cancer is ALL, which is characterized by anaemia, neutropaenia, and thrombocytopaenia. Symptoms include pallor, lethargy, splenomegaly, and petechiae. In contrast, aplastic anaemia is characterized by pancytopenia and hypoplastic bone marrow, which would result in leukopenia instead of leukocytosis. Thalassaemia, a genetic condition that causes anaemia, does not match the patient’s blood film or clinical presentation. ITP, an immune-mediated reduction in platelet count, would not explain the leukocytosis and neutropaenia seen in the patient. Meningitis, which can cause fever and purpura, is unlikely to be bacterial meningitis as it would result in neutrophilia instead of neutropaenia.
Acute lymphoblastic leukaemia (ALL) is a type of cancer that commonly affects children and accounts for 80% of childhood leukaemias. It is most prevalent in children between the ages of 2-5 years, with boys being slightly more affected than girls. Symptoms of ALL can be divided into those caused by bone marrow failure, such as anaemia, neutropaenia, and thrombocytopenia, and other features like bone pain, splenomegaly, and hepatomegaly. Fever is also present in up to 50% of new cases, which may indicate an infection or a constitutional symptom. Testicular swelling may also occur.
There are three types of ALL: common ALL, T-cell ALL, and B-cell ALL. Common ALL is the most common type, accounting for 75% of cases, and is characterized by the presence of CD10 and a pre-B phenotype. Poor prognostic factors for ALL include age less than 2 years or greater than 10 years, a white blood cell count greater than 20 * 109/l at diagnosis, T or B cell surface markers, non-Caucasian ethnicity, and male sex.

As a FY1 in the emergency department, you encounter a mother and her 5-year-old child who is complaining of a rapidly worsening sore throat, high fever, and excessive drooling from the sides of their mouth. The mother admits that the child has missed some vaccinations due to concerns about their negative effects, but is unsure which ones were omitted. Upon examination, the child is sitting on the examination couch, leaning forward and refusing to move. They are pyrexial (38.1C) with overt drooling from the sides of their mouth, and emitting a soft, high-pitched sound on inspiration. What is the most likely causative agent responsible for this child's condition?
Your Answer: Respiratory syncytial virus
Correct Answer: Haemophilus influenzae type B
Explanation:Haemophilus influenzae type B is the primary cause of acute epiglottitis, which is evident in this child’s classic symptoms. It is possible that the child has not received the vaccine for this bacteria, making it a more likely culprit. While Streptococcus pyogenes and other pathogens can also cause this condition, they are less common.
Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B. It is important to recognize and treat it promptly as it can lead to airway obstruction. Although it was once considered a disease of childhood, it is now more common in adults in the UK due to the immunization program. The incidence of epiglottitis has decreased since the introduction of the Hib vaccine. Symptoms include a rapid onset, high temperature, stridor, drooling of saliva, and a tripod position where the patient leans forward and extends their neck to breathe easier. Diagnosis is made by direct visualization, but x-rays may be done to rule out a foreign body.
Immediate senior involvement is necessary, including those who can provide emergency airway support such as anaesthetics or ENT. Endotracheal intubation may be necessary to protect the airway. It is important not to examine the throat if epiglottitis is suspected due to the risk of acute airway obstruction. The diagnosis is made by direct visualization, but only senior staff who are able to intubate if necessary should perform this. Treatment includes oxygen and intravenous antibiotics.

A 1-year-old child is brought to the emergency room with poor muscle tone, gasping respirations, cyanosis, and a heart rate of 80 bpm. The child's APGAR score is 3 and is placed in the sniffing position for airway maintenance. However, there are no changes noted on reassessment. After positive pressure ventilation for 30 seconds, the child is now showing shallow respirations and a heart rate of 50 bpm. Chest compressions are initiated. What is the recommended compression: ventilation ratio for this child?
Your Answer: 2:01
Correct Answer: 3:01
Explanation:If a newborn is healthy, they will have good tone, be pink in color, and cry immediately after delivery. A healthy newborn’s heart rate should be between 120-150 bpm. However, if the infant has poor tone, is struggling to breathe, and has a low heart rate that is not improving, compressions are necessary. According to newborn resuscitation guidelines, compressions and ventilations should be administered at a 3:1 ratio. Therefore, the correct course of action in this scenario is to perform compressions.
Newborn resuscitation involves a series of steps to ensure the baby’s survival. The first step is to dry the baby and maintain their body temperature. The next step is to assess the baby’s tone, respiratory rate, and heart rate. If the baby is gasping or not breathing, five inflation breaths should be given to open the lungs. After this, the baby’s chest movements should be reassessed. If the heart rate is not improving and is less than 60 beats per minute, compressions and ventilation breaths should be administered at a rate of 3:1.
It is important to note that inflation breaths are different from ventilation breaths. The aim of inflation breaths is to sustain pressure to open the lungs, while ventilation breaths are used to provide oxygen to the baby’s body. By following these steps, healthcare professionals can increase the chances of a newborn’s survival and ensure that they receive the necessary care to thrive. Proper newborn resuscitation can make all the difference in a baby’s life, and it is crucial that healthcare professionals are trained in these techniques.

Sarah, a 12-year-old girl with Down's syndrome, visits her GP complaining of fatigue. What medical condition is commonly linked to Down's syndrome?
Your Answer: ADHD
Correct Answer: Hypothyroidism
Explanation:Hypothyroidism is commonly found in individuals with Down syndrome, while the risk of hyperthyroidism is also increased. Type-1 diabetes is more prevalent in those with Down syndrome, but there is no association with ADHD. Fragile X is linked to ADHD, and male breast cancer is not associated with Down syndrome but has been linked to Klinefelter’s syndrome.
Down’s syndrome is a genetic disorder that is characterized by various clinical features. These features include an upslanting of the palpebral fissures, epicanthic folds, Brushfield spots in the iris, a protruding tongue, small low-set ears, and a round or flat face. Additionally, individuals with Down’s syndrome may have a flat occiput, a single palmar crease, and a pronounced sandal gap between their big and first toe. Hypotonia, congenital heart defects, duodenal atresia, and Hirschsprung’s disease are also common in individuals with Down’s syndrome.
Cardiac complications are also prevalent in individuals with Down’s syndrome, with multiple cardiac problems potentially present. The most common cardiac defect is the endocardial cushion defect, also known as atrioventricular septal canal defects, which affects 40% of individuals with Down’s syndrome. Other cardiac defects include ventricular septal defect, secundum atrial septal defect, tetralogy of Fallot, and isolated patent ductus arteriosus.
Later complications of Down’s syndrome include subfertility, learning difficulties, short stature, repeated respiratory infections, hearing impairment from glue ear, acute lymphoblastic leukaemia, hypothyroidism, Alzheimer’s disease, and atlantoaxial instability. Males with Down’s syndrome are almost always infertile due to impaired spermatogenesis, while females are usually subfertile and have an increased incidence of problems with pregnancy and labour.

As a junior doctor in the emergency department, you are asked by a senior doctor to examine a child with a persistent cough. However, they caution you against examining the child's throat as it may lead to airway obstruction. What could be the possible diagnosis for this case?
Your Answer: Glandular fever
Correct Answer: Croup
Explanation:It is not recommended to conduct a throat examination on a patient with croup as it may lead to airway obstruction. This risk is higher in cases of acute epiglottitis, which is a less common condition. However, for the other conditions, throat examination is not contraindicated.
Understanding Croup: A Respiratory Infection in Infants and Toddlers
Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.
The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.
Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.
Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

A 4-year-old patient presents with recurrent chest infections and green sputum production. Upon examination, a chest x-ray reveals ring shadows and bronchial wall thickening in both lung bases. What is the probable diagnosis?
Your Answer: Aspiration pneumonia
Correct Answer: Bronchiectasis
Explanation:Recurrent Chest Infections and Bronchiectasis: A Possible Sign of Cystic Fibrosis
Patients who have a history of recurrent chest infections and x-ray appearances that suggest bronchiectasis may be showing signs of cystic fibrosis. Bronchiectasis is a condition where the airways in the lungs become damaged and widened, leading to a build-up of mucous and bacteria. This can cause recurrent chest infections, which can be difficult to treat. Cystic fibrosis is a genetic condition that affects the production of mucous, leading to thick and sticky secretions that can block the airways and cause infections.
If a patient is showing signs of bronchiectasis, it is important to consider cystic fibrosis as a possible cause. Early diagnosis and treatment of cystic fibrosis can help to manage symptoms and prevent complications. Testing for cystic fibrosis may involve a sweat test, genetic testing, or other diagnostic tests. Treatment may include medications to help clear mucous from the airways, antibiotics to treat infections, and other therapies to manage symptoms.

A 6-hour-old neonate born at 38 weeks gestation is being evaluated on the postnatal ward. The midwives have observed that the baby is jittery and has irregular breathing. The mother had gestational diabetes. At 6 hours old, a heel prick blood glucose measurement was taken and showed the following result:
Glucose 1.2 mmol/L (1.5 – 6)
Apart from these symptoms, the baby appears to be healthy without other complications. What is the most appropriate course of action for managing this newborn?Your Answer: Admit to neonatal unit and encourage to breastfeed
Correct Answer: Admit to neonatal unit and give IV 10% dextrose
Explanation:To manage a newborn with symptomatic hypoglycaemia, the appropriate course of action is to administer a bolus of dextrose to prevent further neurological symptoms such as seizures, coma or apnoea. Admitting the infant to the neonatal unit is recommended to ensure proper care is provided, but breastfeeding alone is not sufficient to correct the hypoglycaemia quickly enough to prevent potential complications. Keeping the infant on the postnatal ward and encouraging breastfeeding is inappropriate, as this setting is not equipped to manage a potentially severely unwell infant. Repeating the heel prick glucose measurement in one hour is unnecessary, as one measurement is enough to initiate treatment without waiting for a second confirmatory test. Obtaining a venous sample for laboratory glucose testing is also unnecessary, as a heel prick test is accurate enough to confirm the hypoglycaemia and treatment should not be delayed while awaiting laboratory confirmation.
Neonatal Hypoglycaemia: Causes, Symptoms, and Management
Neonatal hypoglycaemia is a common condition in newborn babies, especially in the first 24 hours of life. While there is no agreed definition, a blood glucose level of less than 2.6 mmol/L is often used as a guideline. Transient hypoglycaemia is normal and usually resolves on its own, but persistent or severe hypoglycaemia may be caused by various factors such as preterm birth, maternal diabetes mellitus, IUGR, hypothermia, neonatal sepsis, inborn errors of metabolism, nesidioblastosis, or Beckwith-Wiedemann syndrome.
Symptoms of neonatal hypoglycaemia can be autonomic, such as jitteriness, irritability, tachypnoea, and pallor, or neuroglycopenic, such as poor feeding/sucking, weak cry, drowsiness, hypotonia, and seizures. Other features may include apnoea and hypothermia. Management of neonatal hypoglycaemia depends on the severity of the condition and whether the newborn is symptomatic or not. Asymptomatic babies can be encouraged to feed normally and have their blood glucose monitored, while symptomatic or severely hypoglycaemic babies may need to be admitted to the neonatal unit and receive intravenous infusion of 10% dextrose.

A 14-year-old boy comes to the clinic with complaints of central abdominal pain and haematuria that have been present for a week. He also reports experiencing pain in both knees. Upon examination, a non-blanching purpuric rash is observed on his legs and buttocks. Urine dipstick results show blood ++ and protein +. Additionally, his renal function is abnormal with urea levels at 26.3 mmol/l and creatinine levels at 289 μmol/l. What is the most probable diagnosis?
Your Answer: Urinary tract infection
Correct Answer: Henoch–Schönlein purpura
Explanation:Distinguishing Henoch-Schönlein Purpura from Other Conditions: A Brief Overview
Henoch-Schönlein purpura (HSP) is a condition that can present with a range of symptoms, including abdominal pain, non-blanching purpuric rash, arthralgia, haematuria, and renal impairment. It is important to distinguish HSP from other conditions that may have similar symptoms.
Nephrotic syndrome, for example, is characterized by significant proteinuria, hypoalbuminaemia, and oedema, which are not present in HSP. Urinary tract infection, on the other hand, is not associated with a purpuric rash and typically presents with urinary symptoms and positive nitrite and leukocyte dipstick tests.
Goodpasture’s syndrome is a systemic vasculitis that can cause acute renal failure and pulmonary haemorrhage, but it is not typically associated with a purpuric rash. Appendicitis, which can cause an acute abdomen, is unlikely to cause pain for a week and does not typically present with a rash.
In summary, recognizing the unique symptoms of HSP and distinguishing it from other conditions is crucial for accurate diagnosis and appropriate treatment.

A 6-year-old girl presents to your clinic with her parents for a follow-up appointment. She has been experiencing nocturnal enuresis for the past eight months. During her last visit four months ago, she was wetting the bed six to seven nights a week. You advised her parents to limit her fluid intake before bedtime, establish a toileting routine before bed, and implement a reward system for positive behavior. Despite following these recommendations, she continues to wet the bed six to seven nights a week. What would be the most appropriate next step in managing her nocturnal enuresis?
Your Answer: Oxybutynin
Correct Answer: Enuresis alarm
Explanation:When general advice has not been effective, an enuresis alarm is typically the initial treatment option for nocturnal enuresis. However, there are exceptions to this, such as when the child and family find the alarm unacceptable or if the child is over 8 years old and needs rapid short-term reduction in enuresis. Additionally, it is important to note that enuresis alarms have a lower relapse rate compared to other treatments.
Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.
When managing bedwetting, it’s important to look for any underlying causes or triggers, such as constipation, diabetes mellitus, or recent onset UTIs. General advice includes monitoring fluid intake and encouraging regular toileting patterns, such as emptying the bladder before sleep. Reward systems, like star charts, can also be helpful, but should be given for agreed behavior rather than dry nights.
The first-line treatment for bedwetting is an enuresis alarm, which has a high success rate. These alarms have sensor pads that detect wetness and wake the child up to use the toilet. If short-term control is needed, such as for sleepovers, or if the alarm is ineffective or not acceptable to the family, desmopressin may be prescribed. Overall, managing bedwetting involves identifying any underlying causes and implementing strategies to promote continence.

A 9-month-old male is found unresponsive by his father at home. The father immediately calls for emergency services and begins to assess his son's condition. One of the first things the father does is check his son's pulse.
Where should the father check for the pulse during this assessment?Your Answer: Brachial and femoral
Explanation:When assessing for a pulse in infants, the recommended areas to check are the femoral and brachial arteries. This is because the carotid pulse may be difficult to palpate due to the short neck of infants. Checking for a central pulse is important as peripheral pulses may be weaker and harder to feel, especially in unwell patients with peripheral shutdown. It is important to note that according to BLS guidelines, the carotid pulse may only be used in children over 12 months old, making it an inappropriate option for an 8-month-old infant. Therefore, options including the carotid pulse are incorrect.
Paediatric Basic Life Support Guidelines
Paediatric basic life support guidelines were updated in 2015 by the Resuscitation Council. Lay rescuers should use a compression:ventilation ratio of 30:2 for children under 1 year and between 1 year and puberty, a child is defined. If there are two or more rescuers, a ratio of 15:2 should be used.
The algorithm for paediatric basic life support starts with checking if the child is unresponsive and shouting for help. The airway should be opened, and breathing should be checked by looking, listening, and feeling for breaths. If the child is not breathing, five rescue breaths should be given, and signs of circulation should be checked.
For infants, the brachial or femoral pulse should be used, while children should use the femoral pulse. Chest compressions should be performed at a ratio of 15:2, with a rate of 100-120 compressions per minute for both infants and children. The depth of compressions should be at least one-third of the anterior-posterior dimension of the chest, which is approximately 4 cm for an infant and 5 cm for a child.
In children, the lower half of the sternum should be compressed, while in infants, a two-thumb encircling technique should be used for chest compressions. These guidelines are crucial for anyone who may need to perform basic life support on a child, and it is essential to follow them carefully to ensure the best possible outcome.

A 9-month-old baby has become unresponsive in the waiting area of the pediatrician's office for an unknown cause. Basic life support for infants is started, and chest compressions are administered. What is the appropriate technique for performing chest compressions in this scenario?
Your Answer: Two-thumb encircling technique
Explanation:For infants aged younger than one, the recommended technique for chest compression during paediatric BLS is the two-thumb encircling technique. Using one hand to compress the lower half of the sternum or two hands to compress the upper half of the sternum are incorrect methods. Additionally, using two hands to compress the lower half of the sternum or the one-thumb encircling technique are not recognised techniques for providing chest compressions in any circumstance.

A parent brings their 3-week-old girl, who was diagnosed prenatally with Down's syndrome, to hospital. She has been feeding poorly and has been constipated.
On examination, her abdomen is distended.
A colonic biopsy shows absence of ganglion cells in the submucosa.
What is the initial management for this condition?Your Answer: Immediate surgery
Correct Answer: Rectal washouts/bowel irrigation
Explanation:Rectal washouts/bowel irrigation is the initial management for Hirschsprung’s disease. The absence of ganglion cells in the submucosa is a diagnostic criterion, and serial rectal irrigation should be performed before surgery to prevent enterocolitis. Conservative management is not recommended according to current guidelines, and high dose steroids have no role in this scenario. Surgery is the definitive treatment, but serial rectal irrigation should be performed beforehand to prevent enterocolitis. Laxatives are not appropriate for medical management in Hirschsprung’s disease.
Understanding Hirschsprung’s Disease
Hirschsprung’s disease is a rare condition that affects 1 in 5,000 births. It is caused by a developmental failure of the parasympathetic Auerbach and Meissner plexuses, resulting in an aganglionic segment of bowel. This leads to uncoordinated peristalsis and functional obstruction, which can present as constipation and abdominal distension in older children or failure to pass meconium in the neonatal period.
Hirschsprung’s disease is three times more common in males and is associated with Down’s syndrome. Diagnosis is made through a rectal biopsy, which is considered the gold standard. Treatment involves initial rectal washouts or bowel irrigation, followed by surgery to remove the affected segment of the colon.
In summary, Hirschsprung’s disease is a rare condition that can cause significant gastrointestinal symptoms. It is important to consider this condition as a differential diagnosis in childhood constipation, especially in male patients or those with Down’s syndrome. Early diagnosis and treatment can improve outcomes and prevent complications.

A 17 month old girl comes to your GP clinic with symptoms of a viral URTI. While examining her, you notice some developmental concerns. What would be the most worrying sign?
Your Answer: Not toilet trained
Correct Answer: Unable to say 6 individual words with meaning
Explanation:1. At 23-24 months, children typically have a vocabulary of 20-50 words and can form 2-word phrases with meaning.
2. Toilet training usually occurs at or after 3 years of age.
3. By 3 years of age, most children can stand briefly on one leg and hop by age 4.
4. Walking is typically achieved by 18 months, although most children will walk before 17 months.
5. It is common for 23-month-old children to engage in solitary play.Developmental milestones for speech and hearing are important indicators of a child’s growth and development. These milestones can help parents and caregivers track a child’s progress and identify any potential issues early on. At three months, a baby should be able to quieten to their parents’ voice and turn towards sound. They may also start to squeal. By six months, they should be able to produce double syllables like adah and erleh. At nine months, they may say mama and dada and understand the word no. By 12 months, they should know and respond to their own name and understand simple commands like give it to mummy.
Between 12 and 15 months, a child may know about 2-6 words and understand more complex commands. By two years old, they should be able to combine two words and point to parts of their body. Their vocabulary should be around 200 words by 2 1/2 years old. At three years old, they should be able to talk in short sentences and ask what and who questions. They may also be able to identify colors and count to 10. By four years old, they may start asking why, when, and how questions. These milestones are important to keep in mind as a child grows and develops their speech and hearing abilities.
