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: There is no increased risk of the child developing epilepsy
Correct 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 12-year-old female presents to her GP complaining of fatigue, weight loss, frequent urination, and excessive thirst. Her random plasma glucose level is 15 mmol/litre. The patient has a pre-existing condition since childhood that may be responsible for these symptoms. What is the most probable underlying condition?
Your Answer:
Correct Answer: Cystic fibrosis
Explanation:The onset of diabetes in a young person, as described in this presentation, is a classic symptom and has been confirmed by a random blood glucose level of >11 mmol/L. Among the given options, only cystic fibrosis has the potential to cause the development of diabetes. Cystic fibrosis typically manifests in childhood with respiratory symptoms, but as the disease progresses, other symptoms may appear. If the pancreas is affected, it can lead to the development of diabetes mellitus. However, it may take some time for the pancreas to be affected enough to cause diabetes, which is why children with cystic fibrosis may develop diabetes later in life. While the other conditions listed may cause fatigue or weight loss, they do not typically result in polyuria or polydipsia.
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 as a Foundation Year 2 in a GP surgery. A mother brings her 4-year-old girl to see you with a cough. You notice an alert on her notes that states she is on a child protection plan.
Which of the following is true regarding a child protection plan?Your Answer:
Correct Answer: They are devised for children at risk of significant harm
Explanation:Understanding Child Protection Plans and Child in Need Plans
Child protection plans and child in need plans are two different interventions designed to support children who may be at risk of harm or in need of extra support. It is important to understand the differences between these plans and how they are implemented.
Child protection plans are devised for children who are at risk of significant harm. The aim of these plans is to ensure the child’s safety, promote their health and development, and support the family in safeguarding and promoting the child’s welfare. Child protection plans are not voluntary and involve a team of professionals working together to ensure the child’s safety.
On the other hand, child in need plans are voluntary and are designed to support children who may need extra help with their health, safety, or development. These plans identify a lead professional and outline the resources and services needed to achieve the planned outcomes within a specific timeframe.
It is important to note that both plans involve consultation with parents, wider family members, and relevant agencies. Additionally, child protection plans are regularly reviewed to ensure that the child’s safety and well-being are being maintained.
In summary, child protection plans and child in need plans are interventions designed to support children in different ways. Understanding the differences between these plans can help ensure that children receive the appropriate support and interventions they need to thrive.

A father attends his GP to discuss concerns he has about his 12-year-old daughter. Since the age of three, she has had a lot of routines, such as how she organizes her toys and which way she walks to school, and is very rigid about following them. She does not cope at all well with changes to the routine. She struggles to make friends and seems very uncomfortable in social situations. Apart from going to school, she avoids meeting children; she has been to a few birthday parties, but she was very clingy to her father and demanded to be taken home after a few minutes. On examination, the GP is unable to build a rapport with the girl, as she refuses to speak and will not maintain eye contact. She appears fidgety and gets up and down out of her chair on several occasions to try and leave the room. You suspect a diagnosis but advise her father that more assessment will be needed to confirm a diagnosis.
The sign to support the diagnosis is the child's rigid adherence to routines and difficulty coping with changes to the routine, as well as their struggles with social situations and avoidance of meeting other children.Your Answer:
Correct Answer: Less than ten spoken words by age two years
Explanation:Developmental Milestones and Red Flags in Early Childhood
By the age of two years, children should be using 50 or more words. If they do not meet this milestone, there may be a social, speech or hearing issue that needs to be assessed by a paediatric team. Lack of spoken words could be a sign of autistic spectrum disorder (ASD).
A lack of social smile by age three months is considered abnormal and could indicate a social, visual, or cognitive problem. However, it may also signal ASD in some cases.
Parallel play is normal behavior for two-year-olds. They will happily play next to each other but rarely play with each other. It isn’t until the age of three when they usually start to involve other children in playing.
Separation anxiety from parents or carers at age ten months is normal behavior. Children can become upset if they are not with their parents or carer until the new person becomes more familiar to them, usually between the ages of six months and three years.
Temper tantrums at age 18 months are normal behavior. However, if these tantrums persist into later childhood, it could indicate a social or developmental problem.

A 16-year-old girl with short stature visits her GP due to delayed onset of menstruation. During the physical examination, the GP observes a broad neck and detects a systolic murmur in the chest. What condition is most likely causing these symptoms, and with which of the following options is it associated?
Your Answer:
Correct Answer: Coarctation of the aorta
Explanation:Aortic coarctation, a congenital cardiac abnormality characterized by the narrowing of a section of the aorta, is commonly associated with Turner’s syndrome. This condition results in an increase in afterload, which can be detected as a systolic murmur. The patient’s amenorrhea further supports a diagnosis of Turner’s syndrome over other possibilities. Mitral regurgitation, mitral stenosis, and mitral valve prolapse are unlikely to be 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 child is born at 28 weeks gestation and is transferred to the neonatal unit. After a few hours, the child shows signs of nasal flaring, chest wall indrawing, and appears to have jaundice. The observations show a heart rate of 75/min, a respiratory rate of 68/min, and a temperature of 38.2ºC. What is the most common organism responsible for the probable diagnosis?
Your Answer:
Correct Answer: Group B streptococcus
Explanation:The leading cause of early-onset neonatal sepsis in the UK is infection by group B streptococcus.
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 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:
Correct 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 7-year-old girl is brought to the GP by her parents due to concerns about her weight loss. She has been experiencing abdominal pain, diarrhoea, and a poor appetite. She denies having polyuria and her urinalysis results are normal. Upon examination, she is found to be below the 0.4th centile for both height and weight, having previously been on the 9th centile. What series of investigations would be most helpful in confirming a diagnosis?
Your Answer:
Correct Answer: Autoantibodies and CRP
Explanation:Investigating Short Stature in a Child with GI Symptoms
When a child presents with short stature and symptoms suggestive of gastrointestinal (GI) pathology, it is important to consider chronic disease as a possible cause. In this case, the child has fallen across two height and weight centiles, indicating a potential secondary cause. Autoantibodies such as anti-endomysial and anti-tissue transglutaminase may be present in coeliac disease, while a significantly raised CRP would be consistent with inflammatory bowel disease. Further investigation, such as a full blood count and U&E, should also be conducted to exclude chronic kidney disease and anaemia.
While a glucose tolerance test may be used to diagnose diabetes, it is unlikely to be associated with abdominal pain in the absence of glycosuria or ketonuria. Similarly, an insulin stress test may be used for confirmation of growth hormone deficiency, but this condition would not account for the child’s GI symptoms or weight loss. A TSH test may suggest hyper- or hypo-thyroidism, but it is unlikely to support the diagnosis in this case.
It is important to consider all possible causes of short stature in children, especially when accompanied by other symptoms. In this case, measuring autoantibodies and CRP can be useful in making a diagnosis, but further investigation may be necessary for confirmation.

A 5-year-old boy comes to his pediatrician with a complaint of daily nosebleeds for the past week. During the examination, the doctor notices petechiae and bruises on the child's legs. Apart from these symptoms, the child appears to be healthy and does not report any other issues. Blood tests reveal low platelet count, but no other abnormalities are detected. The child's symptoms disappear entirely after four months. What is the likely precursor to these symptoms?
Your Answer:
Correct Answer: Glandular fever
Explanation:ITP, a condition characterized by low platelet count and symptoms such as epistaxis and unexplained bruising/petechiae, may be preceded by a viral infection that is self-limiting and can resolve within a year. The correct answer to the question is glandular fever, as constipation, epileptic fits, asthma attacks, and stress have not been linked to triggering ITP.
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 4-week-old infant, born at term, presents to the Emergency Department with persistent jaundice since birth, pale stools and dark urine. The infant is currently being breastfed.
What is the most probable reason for this infant's jaundice?Your Answer:
Correct Answer: Biliary atresia
Explanation:Understanding the Causes of Jaundice in Infants
Jaundice in newborns that lasts for more than two weeks is considered pathological and requires medical attention. In this case, the infant is exhibiting signs of conjugated hyperbilirubinemia, which is characterized by jaundice with pale stools and dark urine. This is indicative of biliary atresia, a condition that affects the liver and bile ducts.
Cystic fibrosis is another condition that may present in infants with recurrent respiratory infections, but it is not associated with jaundice. Cholelithiasis, or gallstones, is a common cause of obstructive jaundice, but it is more prevalent in middle-aged individuals. Breastfeeding jaundice occurs due to suboptimal milk intake, but it does not cause conjugated hyperbilirubinemia.
Physiological jaundice is common in infants and typically lasts for 1-2 weeks. However, if jaundice persists for more than two weeks, it is considered pathological and requires medical attention. It is important to understand the various causes of jaundice in infants to ensure prompt diagnosis and treatment.

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:
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 baby boy born 3 weeks ago has been experiencing persistent jaundice since 72 hours after birth. His parents have observed that he is hesitant to breastfeed and his urine appears dark. During your examination, you confirm that the infant is jaundiced and has an enlarged liver. Upon reviewing his blood work, you find that he has conjugated hyperbilirubinemia. His serum alpha-1 antitrypsin levels and electrophoresis are normal, and the neonatal heel prick test conducted at birth was negative. What is the recommended treatment for this condition?
Your Answer:
Correct Answer: Early surgical treatment
Explanation:Biliary atresia is the primary cause of prolonged jaundice in this infant, which occurs due to an obstruction in the flow of bile within the extrahepatic biliary system. To confirm the diagnosis, bilirubin levels, liver function tests, and abdominal ultrasound are performed, while alpha-1 antitrypsin deficiency and cystic fibrosis are excluded as differential diagnoses. The Kasai procedure, a surgical intervention, is the preferred treatment option to restore bile flow and prevent further hepatic damage. Postoperative management may involve IV antibiotics to manage complications such as ascending cholangitis, while ursodeoxycholic acid may be used to augment weight gain and decrease episodes of cholangitis. Optimizing feeds is also important, but not the primary management option in this case, as the heel prick test has excluded CF. Infusion of alpha-1 antitrypsin is not necessary, as the infant’s serum levels are normal.
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 13-year-old boy was hospitalized due to a two-week history of high-grade fever and bleeding gums. Upon examination of his peripheral blood, multiple blasts were observed, some of which displayed Auer rods. Which congenital condition is most strongly linked to this presentation?
Your Answer:
Correct Answer: Trisomy 21 (Down syndrome)
Explanation:Congenital syndromes associated with acute myeloblastic leukemia
Acute myeloblastic leukemia (AML) can be associated with various congenital syndromes, including severe congenital neutropenia (Kostmann syndrome), Bloom syndrome, Fanconi anemia, Diamond-Blackfan syndrome, neurofibromatosis type 1, and Li Fraumeni syndrome. However, Gardner syndrome, or familial colorectal polyposis, is not linked to AML. Trisomy 18 (Edward syndrome) is a chromosomal abnormality that has a poor prognosis but is not typically associated with AML. Klinefelter syndrome, a genetic disorder characterized by an extra X chromosome in males, may increase the risk of breast cancer and germ cell tumors, but the evidence for an association with AML is inconclusive. Haemophilia, a bleeding disorder caused by a deficiency in clotting factors, does not predispose to AML or mucosal bleeding.

Parents bring their infant to see you because their child is not growing normally. There is no family history of note. On examination, he is noted to have a large head relative to the limbs. The limbs are relatively shortened, compared to the trunk.
What is the molecular basis for this condition?Your Answer:
Correct Answer: Activation of the fibroblast growth factor 3 (FGF3) receptor
Explanation:There are several genetic mutations that can cause developmental abnormalities and disorders. One such mutation is the activation of the fibroblast growth factor 3 (FGF3) receptor, which leads to achondroplasia and stunted bone growth. Another mutation affects the fibrillin-1 gene, causing Marfan’s syndrome and resulting in tall stature, joint hypermobility, and cardiac abnormalities. Mutations in collagen genes can lead to disorders like osteogenesis imperfecta, Ehlers-Danlos syndrome, and Alport disease. Trisomy 18, or Edwards’ syndrome, is caused by an extra copy of chromosome 18 and results in severe developmental abnormalities and organ system dysfunction. Trisomy 21, or Down syndrome, is caused by an extra copy of chromosome 21 and leads to characteristic physical features such as dysplastic ears and a high arched palate, as well as intellectual disability.

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:
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 5-year-old child has a history of chronic constipation for the past two years and chronic abdominal distention with vomiting for six months. Hirschsprung's disease is suspected. What investigation from the list below provides the most conclusive diagnosis for this condition?
Your Answer:
Correct Answer: Rectal biopsy
Explanation:While anorectal manometry can aid in the diagnosis of Hirschsprung’s disease, the gold standard for confirmation remains rectal biopsy. This is due to the fact that microscopic analysis reveals the absence of ganglionic nerve cells in the affected area.
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 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:
Correct 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.

What are the typical vaccines administered to adolescents aged 12-19 years?
Your Answer:
Correct 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.

What is the preferred investigation for diagnosing vesicoureteric reflux in pediatric patients?
Your Answer:
Correct Answer: Micturating cystourethrogram
Explanation:Understanding Vesicoureteric Reflux
Vesicoureteric reflux (VUR) is a condition where urine flows back from the bladder into the ureter and kidney. This is a common urinary tract abnormality in children and can lead to urinary tract infections (UTIs). In fact, around 30% of children who present with a UTI have VUR. It is important to investigate for VUR in children following a UTI as around 35% of children develop renal scarring.
The pathophysiology of VUR involves the ureters being displaced laterally, which causes a shortened intramural course of the ureter. This means that the vesicoureteric junction cannot function properly. VUR can present in different ways, such as hydronephrosis on ultrasound during the antenatal period, recurrent childhood UTIs, and reflux nephropathy, which is chronic pyelonephritis secondary to VUR. Renal scarring can also produce increased quantities of renin, which can cause hypertension.
To diagnose VUR, a micturating cystourethrogram is usually performed. A DMSA scan may also be done to check for renal scarring. VUR is graded based on the severity of the condition, with Grade I being the mildest and Grade V being the most severe.
Overall, understanding VUR is important in preventing complications such as UTIs and renal scarring. Early diagnosis and management can help improve outcomes for children with this condition.

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:
Correct 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

Question 22

A 6-month-old boy is brought to the paediatrics emergency department by his parents. His parents report that he has had a fever for 2 days with reduced activity and feeding. On examination, he is not smiling, his respiratory rate is 50 breaths/minute (normal range: 30-60 breaths/minute) and his heart rate is 155 beats/minute (100-160 beats/minute). He also has reduced skin turgor and looks pale. A nurse looks up the NICE traffic light system to identify his risk of serious illness.
What is the most concerning symptom in this patient?Your Answer:
Correct Answer: Reduced skin turgor
Explanation:According to the NICE traffic light system, reduced skin turgor is a red flag symptom in children. This system is used to identify the risk of serious illness in children. Decreased activity is considered an amber symptom, while age <6 months is not a red flag symptom. Age 3-6 months with a temperature of >=39ºC is an amber flag symptom, and age <3 months with a temperature of >=38°C is a red flag symptom. A respiratory rate of >60 breaths/minute is also a red flag symptom. Finally, a heart rate of >160 beats/minute in children under 12 months is an amber flag symptom.
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 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:
Correct 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 12-hour-old neonate is evaluated in the neonatal unit after a normal vaginal delivery at 35 weeks' gestation. The mother reports no issues thus far. During the examination, a continuous 'machinery-like' murmur is heard, and a left subclavicular thrill is observed. The neonate has a large-volume collapsing pulse. An echocardiogram is performed, revealing the suspected defect but no other anomalies. What is the most suitable course of action at this point?
Your Answer:
Correct Answer: Give indomethacin to the neonate
Explanation:The most likely diagnosis based on the examination findings is patent ductus arteriosus (PDA). To close the PDA, indomethacin (or ibuprofen) should be given to inhibit prostaglandin synthesis. Giving prostaglandin E1 would have the opposite effect and maintain the patency of the duct, which is not necessary in this scenario. Simply observing the neonate over time is not appropriate, and routine or urgent surgical referrals are not needed at this stage. First-line management should be to try medical closure of the PDA using indomethacin, which is effective in most cases.
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 healthy toddler is playing outside but suddenly stops breathing. The toddler's heart rate is over 100 bpm, but the skin colour is blue and the toddler is not moving. After calling for help and checking for a pulse, what is the most appropriate action to take?
Your Answer:
Correct Answer: Give five breaths of air via a face mask
Explanation:Steps for Neonatal Resuscitation
Neonatal resuscitation is a crucial process that can save a newborn’s life. Here are the steps to follow:
1. Dry the baby and assess its tone, breathing, and heart rate. If the baby is not breathing or gasping, open the airway by placing the baby on its back with the head in a neutral position. Give five inflation breaths of air via a face mask.
2. If the heart rate increases but the baby still cannot breathe, give breaths at a rate of 30-40 per minute until the baby can breathe independently.
3. Cardiac massage should only be done if the chest is not moving or the heart rate drops below 60 bpm. In this case, commence cardiac massage at a rate of three compressions to one breath.
4. Suction of the airways should only be done if there is an obvious airway obstruction that cannot be corrected by airway repositioning manoeuvres.
5. While it is important to keep the baby warm, avoid wrapping it tightly in a towel as it can obstruct the resuscitation process.
6. Intubation is not the first step in the resuscitation process. It is an option when resuscitation is failing and is the decision of a senior paediatrician.
By following these steps, you can increase the chances of a successful neonatal resuscitation.

Which one of the following statements regarding osteosarcoma is true?
Your Answer:
Correct Answer: More than 90% of children survive to adulthood
Explanation:Retinoblastoma is a prevalent type of eye cancer that is commonly found in children, with an average age of diagnosis at 18 months. It is caused by a loss of function of the retinoblastoma tumor suppressor gene on chromosome 13, which is inherited in an autosomal dominant pattern. About 10% of cases are hereditary. The most common presenting symptom is the absence of red-reflex, which is replaced by a white pupil (leukocoria). Other possible features include strabismus and visual problems.
When it comes to managing retinoblastoma, enucleation is not the only option. Depending on how advanced the tumor is, other treatment options include external beam radiation therapy, chemotherapy, and photocoagulation. The prognosis for retinoblastoma is excellent, with over 90% of patients surviving into adulthood.

A 31-year-old woman expresses a concern during her booking appointment that is forwarded to the obstetrician. She discloses that her previous child was born with a congenital defect and inquires if any action needs to be taken during her current pregnancy. Upon reviewing the notes from her previous pregnancy, the obstetrician notes that the neonate had a left subclavicular thrill, a heaving apex beat, and a continuous 'machinery-like' murmur.
What is the appropriate course of action for managing this defect?Your Answer:
Correct Answer: Indomethacin to be given to the neonate, postnatally
Explanation:The correct management for patent ductus arteriosus (PDA) in a neonate is to administer indomethacin postnatally, not to the mother during the antenatal period. If a PDA is identified on examination, indomethacin is given to the neonate to inhibit prostaglandin synthesis and close the defect. Dexamethasone is not used for PDA management but for fetal lung maturation in cases of suspected premature delivery. Administering indomethacin to the mother antenatally or prostaglandin E1 antenatally or postnatally is incorrect. Prostaglandin E1 is only given postnatally if another congenital heart defect is found that requires surgery.

A paediatrician is called to assess a 3-day-old neonate born at 37+2 weeks gestation due to concerns in the newborn physical examination. The neonate has absent fundal reflexes bilaterally and a loud machinery murmur is heard on auscultation. Automated otoacoustic emission suggests sensorineural deafness. The mother recently arrived from overseas where she was unable to access antenatal care. In the first trimester, she had an exanthematous rash on her trunk, but the pregnancy was otherwise unremarkable. What is the likely diagnosis for this neonate?
Your Answer:
Correct Answer: Congenital rubella syndrome
Explanation:Congenital rubella syndrome is the correct answer, as it is known to cause both sensorineural deafness and congenital cataracts. Although rubella has been eliminated in many Western countries due to vaccination, it is still prevalent in some African, Middle Eastern, and Southeast Asian countries. Rubella may present with a non-specific viral rash, similar to the one described in this patient. Congenital rubella syndrome is also associated with a patent ductus arteriosus, which can cause a machinery murmur.
Alport syndrome is not the correct answer, as it is associated with congenital sensorineural hearing loss but not with congenital cataracts. Alport syndrome is also linked to renal impairment and nephritic syndrome.
Congenital cytomegalovirus infection is not the correct answer, as it is associated with congenital sensorineural deafness but not typically with congenital cataracts. Congenital CMV infection may also cause cerebral palsy, anemia, and jaundice.
Congenital toxoplasmosis infection is not the correct answer, as it would not typically present with sensorineural deafness, congenital cataracts, or a patent ductus arteriosus. Congenital toxoplasmosis infection is known to cause cerebral calcification, chorioretinitis, and hydrocephalus.
Congenital Infections: Rubella, Toxoplasmosis, and Cytomegalovirus
Congenital infections are infections that are present at birth and can cause various health problems for the newborn. The three major congenital infections that are commonly encountered in medical examinations are rubella, toxoplasmosis, and cytomegalovirus. Cytomegalovirus is the most common congenital infection in the UK, and maternal infection is usually asymptomatic.
Each of these infections has characteristic features that can help with diagnosis. Rubella can cause congenital cataracts, sensorineural deafness, and congenital heart disease, among other things. Toxoplasmosis can cause growth retardation, cerebral palsy, and visual impairment, among other things. Cytomegalovirus can cause microcephaly, cerebral calcification, and chorioretinitis, among other things.
It is important to be aware of these congenital infections and their potential effects on newborns. Early diagnosis and treatment can help prevent or minimize health problems for the newborn.

A couple brings their 5 week old formula fed baby to the short stay paediatric ward due to persistent non-bilious vomiting and increasing lethargy. However, the baby's appetite remains substantial. During examination, the baby appears pale and visible peristalsis is observed in the left upper quadrant. What is the probable diagnosis?
Your Answer:
Correct Answer: Pyloric stenosis
Explanation:This presentation may indicate the possibility of pyloric stenosis, as there are signs of visible peristalsis where the stomach is attempting to move its contents past the obstruction. The vomiting is non-bilious, which suggests that the obstruction is located before the second part of the duodenum where bile enters the digestive system. This is different from malrotation and duodenal atresia.
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.
