A 1-year-old child is diagnosed with multiple congenital abnormalities such as an extra finger on each hand, microphthalmia, microcephaly, and cleft palate and lip. Which chromosome is most likely to be affected in this case?
Your Answer: 13
Explanation:A newborn has been diagnosed with Patau syndrome, which is caused by an extra full copy of chromosome 13 (trisomy 13). This chromosomal abnormality often results in physical and mental disabilities, with distinguishing features including polydactyly, cleft lips and palates, microcephaly, and microphthalmia. Unfortunately, many infants with Patau syndrome do not survive beyond their first year of life. Those who do survive often experience intellectual and motor disabilities.
Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions. Edward’s syndrome, also known as trisomy 18, is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. Fragile X syndrome is characterized by learning difficulties, macrocephaly, long face, large ears, and macro-orchidism. Noonan syndrome is characterized by a webbed neck, pectus excavatum, short stature, and pulmonary stenosis. Pierre-Robin syndrome is characterized by micrognathia, posterior displacement of the tongue, and cleft palate. Prader-Willi syndrome is characterized by hypotonia, hypogonadism, and obesity. William’s syndrome is characterized by short stature, learning difficulties, friendly, extrovert personality, and transient neonatal hypercalcaemia. Cri du chat syndrome, also known as chromosome 5p deletion syndrome, is characterized by a characteristic cry, feeding difficulties and poor weight gain, learning difficulties, microcephaly and micrognathism, and hypertelorism. It is important to note that Treacher-Collins syndrome is similar to Pierre-Robin syndrome, but it is autosomal dominant and usually has a family history of similar problems.

A mother brings in her 8-year-old daughter to the pediatrician's office. She is worried because she has noticed that her daughter has been showing signs of breast development for the past 3 months. The mother is concerned that her daughter may be experiencing early puberty. What course of action would you recommend?
Your Answer: Refer to paediatric specialist for further investigation
Correct Answer: Reassure her that this is normal development
Explanation:If a girl develops secondary sexual characteristics before the age of 8 and a boy before the age of 9, it is considered precocious puberty. However, if a girl is developing within the normal time frame, such as breast development, there is no need for the mother to worry or seek medical attention. Checking sex hormones or referring to a pediatric specialist is unnecessary as the child is developing normally and the breast development will continue as part of the natural pubertal process.
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.

What is the cause of scarlet fever?
Your Answer: Group A haemolytic streptococci
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 desquamination 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.

At what point in the childhood immunisation schedule is the Meningitis B vaccine administered?
Your Answer: 2, 3, and 4 months
Correct Answer: 2, 4, and 12 months
Explanation:The most prevalent cause of meningococcal disease in children in the UK is currently Meningitis B. In 2015, the Meningitis B vaccination was added to the NHS routine childhood immunisation schedule. It is administered at 2, 4, and 12 months of age, in conjunction with other immunisations in the schedule. If given at a different time, doses must be spaced at least 2 months apart. For children over one year old, only two doses are necessary.
Meningitis B Vaccine Now Part of Routine NHS Immunisation
Children in the UK have been vaccinated against meningococcus serotypes A and C for many years, leaving meningococcal B as the most common cause of bacterial meningitis in the country. However, a new vaccine called Bexsero has been developed to combat this strain. Initially, the Joint Committee on Vaccination and Immunisation (JCVI) rejected the use of Bexsero due to a cost-benefit analysis. However, the decision was eventually reversed, and the vaccine has been added to the routine NHS immunisation schedule.
The vaccine is administered in three doses at 2 months, 4 months, and 12-13 months. Additionally, Bexsero will be available on the NHS for individuals at high risk of meningococcal disease, such as those with asplenia, splenic dysfunction, or complement disorder. This new vaccine is a significant step in protecting children and vulnerable individuals from meningitis B.

A 6-week-old girl is brought to the pediatrician by her father with symptoms of vomiting and diarrhea for the past 5 days. She has also developed a new rash that is bothering her and has a runny nose. The father denies any weight loss, fever, or other family members being sick.
Upon further questioning, the father reveals that he has recently introduced formula milk as he is planning to return to work soon and wants the baby to get used to it. The pediatrician suspects that the infant may have an intolerance to cow's milk protein.
What would be the most appropriate alternative feed to try for this baby?Your Answer: Extensively hydrolysed formula
Explanation:Formula options for infants with different types of intolerance vary. For infants with cow’s milk protein intolerance, a partially hydrolysed formula is recommended as it contains proteins that are less allergenic. Amino acid-based formula is suitable for infants with severe intolerance, although it may not be as palatable. High protein formula is used for pre-term infants, but recent studies suggest that it may increase the risk of obesity in the long-term. Lactose-free formula is appropriate for infants with lactose intolerance, which is characterized by gastrointestinal symptoms rather than rash and runny nose.
Understanding Cow’s Milk Protein Intolerance/Allergy
Cow’s milk protein intolerance/allergy (CMPI/CMPA) is a condition that affects around 3-6% of children, typically presenting in the first 3 months of life in formula-fed infants. Both immediate and delayed reactions can occur, with CMPA used for immediate reactions and CMPI for mild-moderate delayed reactions. Symptoms include regurgitation, vomiting, diarrhea, urticaria, atopic eczema, colic symptoms, wheeze, chronic cough, and rarely, angioedema and anaphylaxis. Diagnosis is often clinical, with investigations including skin prick/patch testing and total IgE and specific IgE (RAST) for cow’s milk protein.
Management for formula-fed infants includes using extensive hydrolyzed formula (eHF) milk as the first-line replacement formula for mild-moderate symptoms and amino acid-based formula (AAF) for severe CMPA or if no response to eHF. Around 10% of infants are also intolerant to soya milk. For breastfed infants, mothers should eliminate cow’s milk protein from their diet and consider prescribing calcium supplements to prevent deficiency. eHF milk can be used when breastfeeding stops until at least 6 months and up to 12 months of age.
The prognosis for CMPI is usually good, with most children becoming milk tolerant by the age of 3-5 years. However, a challenge is often performed in a hospital setting as anaphylaxis can occur. It is important to refer infants with severe symptoms to a pediatrician for management. Understanding CMPI/CMPA and its management can help parents and healthcare providers provide appropriate care for affected children.

A 6-year-old girl is seen in surgery. Her father is concerned about her temperature, which she has had for the past 72 hours. He reports that she is eating and drinking around 75% of usual. She is still producing wet nappies and does not have any vomiting or diarrhoea. Examination reveals a temperature of 38.5°C, heart rate 120 beats/min, a capillary refill time <2 s, no rash, no cough, tender cervical lymphadenopathy, and a red exudative throat with pus on the right tonsil.
Which of the following is the best action to take?
Select the SINGLE best action from the list below.Your Answer: Manage at home with antibiotics and antipyretics
Explanation:Based on the NICE Guideline on ‘Fever in under 5s’, this child is considered low risk for serious illness as they have no high-risk or red or amber features on traffic-light scoring. The child can be managed at home with antibiotics and antipyretics unless they deteriorate. The Centor criteria can be used to determine the likelihood of a sore throat being due to bacterial infection, and this child scores 4, indicating that antibiotics should be prescribed. Admitting the child to the hospital or administering IM benzylpenicillin would be inappropriate in this case. While the child has no red flags for serious illness, they are likely to have an acute bacterial infection that could benefit from antibiotics.

A 7-year-old girl is brought in for evaluation. Her medical records indicate that she has previously received treatment for constipation, but is generally healthy. The mother reports that the child is currently passing only one hard stool every 3-4 days, which resembles 'rabbit droppings'. There is no history of overflow soiling or diarrhea. The abdominal examination is normal. What is the most suitable initial intervention?
Your Answer: Advice on diet/fluid intake
Correct Answer: Advice on diet/fluid intake + Movicol Paediatric Plain
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 35-year-old primip has a stillborn baby at 34 weeks gestation. The infant presents with microcephaly, micrognathia, and club feet. What is the diagnosis?
Your Answer: Trisomy 13
Correct Answer: Trisomy 18
Explanation:Edward’s syndrome is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. The baby affected by this syndrome will have experienced slow growth in the womb and will have a low birthweight. Unfortunately, around half of those who survive to birth will pass away within two weeks, and only one in every five will live for at least three months. The survival rate beyond one year is only one in every 12 babies born with Edwards’ syndrome. This information is according to NHS Choices.
Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions. Edward’s syndrome, also known as trisomy 18, is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. Fragile X syndrome is characterized by learning difficulties, macrocephaly, long face, large ears, and macro-orchidism. Noonan syndrome is characterized by a webbed neck, pectus excavatum, short stature, and pulmonary stenosis. Pierre-Robin syndrome is characterized by micrognathia, posterior displacement of the tongue, and cleft palate. Prader-Willi syndrome is characterized by hypotonia, hypogonadism, and obesity. William’s syndrome is characterized by short stature, learning difficulties, friendly, extrovert personality, and transient neonatal hypercalcaemia. Cri du chat syndrome, also known as chromosome 5p deletion syndrome, is characterized by a characteristic cry, feeding difficulties and poor weight gain, learning difficulties, microcephaly and micrognathism, and hypertelorism. It is important to note that Treacher-Collins syndrome is similar to Pierre-Robin syndrome, but it is autosomal dominant and usually has a family history of similar problems.

A 12-year-old boy visits his General Practitioner with complaints of a sore throat, fever and cervical lymphadenopathy. The doctor prescribes amoxicillin. After four days of taking the antibiotics, the boy develops a highly itchy, maculopapular rash. His blood tests from four days ago reveal a lymphocytosis. What is the most probable diagnosis?
Your Answer: Glandular fever
Explanation:Diagnosing Glandular Fever: Understanding Symptoms and Differential Diagnosis
Glandular fever, also known as infectious mononucleosis, is a viral illness that can cause a range of symptoms, including fever, sore throat, fatigue, and swollen lymph nodes. One common symptom is the development of a maculopapular rash, which can be triggered by taking penicillin. However, it is important to consider other potential diagnoses and rule out conditions such as dermatitis herpetiformis, allergy to penicillin, herpes zoster, and streptococcal throat infection.
To confirm a diagnosis of glandular fever, healthcare providers may perform a full blood count to check for lymphocytosis and atypical lymphocytes. Epstein-Barr virus (EBV) serology may also be tested in certain cases. Treatment for glandular fever is primarily supportive, and patients are advised to avoid contact sports to reduce the risk of splenic rupture.
By understanding the symptoms and differential diagnosis of glandular fever, healthcare providers can accurately diagnose and manage this viral illness.

A couple from Bangladesh, parents of a 13-year-old boy, seek guidance. They have recently moved to the UK and have been advised by immigration officials that their son should receive the BCG vaccine for tuberculosis. The boy is currently healthy and shows no symptoms. What would be the most suitable course of action?
Your Answer: Arrange a tuberculin skin test
Explanation:Before administering the vaccine, it is crucial to conduct a tuberculin skin test to rule out any previous exposure to tuberculosis.
The BCG Vaccine: Who Should Get It and How It’s Administered
The Bacille Calmette-Guérin (BCG) vaccine is a vaccine that provides limited protection against tuberculosis (TB). In the UK, it is given to high-risk infants and certain groups of people who are at risk of contracting TB. The vaccine contains live attenuated Mycobacterium bovis and also offers limited protection against leprosy.
The Greenbook provides guidelines on who should receive the BCG vaccine. It is recommended for all infants living in areas of the UK where the annual incidence of TB is 40/100,000 or greater, as well as infants with a parent or grandparent who was born in a country with a high incidence of TB. The vaccine is also recommended for previously unvaccinated tuberculin-negative contacts of cases of respiratory TB, new entrants under 16 years of age who were born in or have lived for a prolonged period in a high-risk country, healthcare workers, prison staff, staff of care homes for the elderly, and those who work with homeless people.
Before receiving the BCG vaccine, any person being considered must first be given a tuberculin skin test, except for children under 6 years old who have had no contact with tuberculosis. The vaccine is given intradermally, normally to the lateral aspect of the left upper arm. It can be given at the same time as other live vaccines, but if not administered simultaneously, there should be a 4-week interval.
There are some contraindications for the BCG vaccine, including previous BCG vaccination, a past history of tuberculosis, HIV, pregnancy, and a positive tuberculin test (Heaf or Mantoux). It is not given to anyone over the age of 35, as there is no evidence that it works for people of this age group.

A 7-year-old child is brought to see you by his parents, who are concerned because he still wets his bed every night. A urine culture is normal; urine is negative for glucose and protein.
What would be the most appropriate approach to managing this child's bedwetting?Your Answer: Reassurance to parents with general advice
Explanation:Understanding and Managing Nocturnal Enuresis in Children
Nocturnal enuresis, or bedwetting, is a common issue among children. While it can sometimes be caused by an underlying medical condition, such as a urinary tract infection or diabetes, in most cases it is simply a developmental issue that will resolve on its own over time.
It is important to have a medical evaluation to rule out any underlying medical conditions, but once those have been ruled out, treatment is generally not recommended until the child is at least six years old. In the meantime, parents can use star charts and enuresis alarms to help motivate their child to stay dry at night.
It is also important to consider any psychological issues that may be contributing to the problem. Parents should ask their child about their school performance, friendships, and home life, and try to speak to the child alone if possible to get a better understanding of any stressors that may be affecting them.
There is no need for a referral for an ultrasound scan unless there is a suspicion of a structural abnormality. Desmopressin nasal spray can be prescribed for short-term relief, but oral imipramine is no longer recommended. Prophylactic antibiotics are also not indicated for nocturnal enuresis.
Overall, parents should be reassured that bedwetting is a common issue that many children experience, and with time and patience, it will likely resolve on its own.

A 25-year-old male patient visits the GP clinic complaining of left ear pain that has been present for 3 days. The patient is new to the clinic and there is no medical history available on the system. Upon examination, you observe the patient's facial features, which include upslanting palpebral fissures, prominent epicanthic folds, low-set ears, and a protruding tongue. Otoscopy examination of the left ear reveals a bulging tympanic membrane. What is the probable diagnosis?
Your Answer: Mastoiditis
Correct Answer: Acute otitis media
Explanation:Acute otitis media can be indicated by a bulging tympanic membrane, which is a common occurrence in individuals with Down’s syndrome. Lesions in the attic area of the tympanic membrane are typically associated with cholesteatoma. Otitis externa does not typically result in a bulging otitis media, while otitis media with effusion is characterized by a retracted tympanic membrane and a feeling of fullness in the ear.
Vision and Hearing Issues in Down’s Syndrome
Individuals with Down’s syndrome are prone to experiencing vision and hearing problems. In terms of vision, they are more likely to have refractive errors, which can cause blurred vision. Strabismus, a condition where the eyes do not align properly, is also common in 20-40% of individuals with Down’s syndrome. Cataracts, both congenital and acquired, are more prevalent in this population, as well as recurrent blepharitis, an inflammation of the eyelids. Glaucoma, a condition that damages the optic nerve, is also a potential issue.
Regarding hearing, otitis media and glue ear are very common in individuals with Down’s syndrome, which can lead to hearing problems. Otitis media is an infection of the middle ear, while glue ear is a buildup of fluid in the middle ear that can cause temporary hearing loss. It is important for individuals with Down’s syndrome to receive regular vision and hearing screenings to detect and address any potential issues.

A 1-month-old infant presents with low-set ears, rocker bottom feet, and overlapping of fingers. What is the probable diagnosis?
Your Answer: Fragile X
Correct Answer: Edward's syndrome
Explanation:Edward’s syndrome is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers, which are present at birth.
Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions.

A 3-year-old boy is brought to the paediatric urology clinic due to recurrent urinary tract infections. A renal ultrasound revealed dilatation of the ureters. The boy's father remembers having a similar issue with a valve in his ureters during childhood, resulting in urine flowing back towards the kidneys. What is the most suitable test to assess the severity of the probable underlying cause?
Your Answer: Micturating cystography
Explanation:Vesicoureteral reflux (VUR) is a likely cause of recurrent urinary tract infections (UTIs) in children under 6 years old. The family history, age of the patient, and abnormal ultrasound findings suggest VUR as the underlying issue. To determine the severity of VUR, a voiding cystourethrogram (micturating cystography) is necessary. This test involves injecting dye into the bladder via a catheter and taking x-ray images while the child urinates. Early detection of VUR is crucial to prevent kidney scarring (reflux nephropathy).
Bladder ultrasound is not an appropriate method for grading VUR severity. While ultrasound imaging of the urinary tract, including the kidneys, can be useful, it cannot grade VUR severity.
A CT abdomen is not necessary and would expose the child to unnecessary radiation.
A dimercaptosuccinic acid (DMSA) scan can assess renal parenchymal defects resulting from VUR and is typically performed within six months of an acute infection in children with recurrent UTIs. However, it cannot grade the severity of VUR.
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.

An infant develops bile-stained vomiting; an abdominal X-ray shows a ‘double bubble’ appearance. The infant is also hypotonic with brachycephaly.
Which of the following is the most likely diagnosis?
Your Answer: Trisomy 21
Explanation:Genetic Disorders and Associated Phenotypic Features
Trisomy 21: Down Syndrome and Duodenal Atresia
Neonates with Down syndrome have an increased risk of duodenal atresia, accounting for around a third of cases. Prenatal imaging can detect this condition, which presents with bilious vomiting within hours of birth. Down syndrome is also characterized by distinct physical features such as brachiocephaly, upward slanting palpebral fissures, and joint hyperflexibility.45,XO: Turner Syndrome and Cardiac Defects
Turner syndrome affects females with a genetic complement of 45XO. It is characterized by short stature, webbed neck, and lymphoedema. Cardiac defects, including coarctation of the aorta, may also be present.Fragile X: Learning Disability and Autism
Fragile X is a common X-linked form of learning disability and autism. Physical features are difficult to detect in infancy, but delayed motor milestones and speech and language delay may be present. Macro-orchidism is almost universal post-puberty, and cardiac defects, including mitral valve prolapse, may occur.Trisomy 18: Edwards’ Syndrome and Neonatal Hypotonia
Trisomy 18, or Edwards’ syndrome, is characterized by neonatal hypotonia, apnoea, and seizures. There is severe psychomotor and growth retardation, microcephaly, and microphthalmia. Over 90% have cardiac defects, commonly VSD, as well as anomalies in most organ systems.47,XXY: Klinefelter’s Syndrome and Infertility
Klinefelter’s syndrome affects males with a genetic complement of either 47,XXY or 48,XXXY. It is a random mutation, not inherited, and is characterized by tall stature, poorly developed testes or cryptorchidism, and gynaecomastia. Infertility is common. Physical features are not obvious in infancy. -

You are assessing a 10-month-old infant with a viral upper respiratory tract infection. Despite being clinically stable, the mother inquires about the child's development towards the end of the consultation. The infant is observed to point and babble 'mama' and 'dada', but has not yet developed any other words. She appears to be timid and cries when being examined. The infant has an early pincer grip and can roll from front to back, but is unable to sit without support. How would you evaluate her developmental progress?
Your Answer: Normal development
Correct Answer: Isolated delay in gross motor skills
Explanation:A delay in gross motor skills is likely as most babies are able to sit without support by 7-8 months, but the other developmental features are normal for her age. If the delay persists at 12 months, referral to a paediatrician should be considered.
Gross Motor Developmental Milestones
Gross motor skills refer to the ability to use large muscles in the body for activities such as crawling, walking, running, and jumping. These skills are essential for a child’s physical development and are achieved through a series of developmental milestones.
At 3 months, a baby should have little or no head lag when pulled to sit and should have good head control when lying on their abdomen. By 6 months, they should be able to lift and grasp their feet when lying on their back, pull themselves to a sitting position, and roll from front to back. At 9 months, they should be able to pull themselves to a standing position and crawl. By 12 months, they should be able to cruise and walk with one hand held. At 18 months, they should be able to walk unsupported and squat to pick up a toy. By 2 years, they should be able to run and walk up and down stairs holding onto a rail. At 3 years, they should be able to ride a tricycle using pedals and walk up stairs without holding onto a rail. By 4 years, they should be able to hop on one leg.
It is important to note that while the majority of children crawl on all fours before walking, some children may bottom-shuffle, which is a normal variant that runs in families. These milestones serve as a guide for parents and healthcare professionals to monitor a child’s physical development and identify any potential delays or concerns.

The parents of a 15-month-old boy visit their GP with concerns about his eyes. They have noticed that in some photos there is no 'red eye' on the right side. Upon examination, the boy is found to have an esotropic strabismus and a loss of the red-reflex in the right eye. There is a family history of a grandparent who had an enucleation as a child.
What is the probable diagnosis?Your Answer: Retinoblastoma
Explanation:The absence of the red-reflex may be a symptom of a congenital cataract, but this condition is typically identified at birth or during routine infant screenings. Additionally, a congenital cataract would not account for the familial history of enucleation.
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 10-year-old boy has been diagnosed with constipation.
What is the recommended first line treatment for constipation in children?
Your Answer: Macrogol (Movicol)
Explanation:First-Line Treatment for Constipation in Children: Macrogol (Movicol)
When a child is diagnosed with constipation and secondary causes have been ruled out, treatment can be initiated. The first-line treatment recommended by NICE is macrogol, which is available as Movicol Paediatric Plain or Movicol depending on the child’s age. The dose is escalated until regular and good consistency stools are achieved. However, it is important to check for faecal impaction before starting maintenance treatment. Suppositories and enemas should not be routinely used in primary care. If macrogol is not tolerated or if there is a particularly hard stool, a stool softener such as lactulose can be used. A stimulant laxative such as senna can also be used as an alternative to macrogol.

Which of the following examples of infant jaundice from the list below is the most concerning?
Your Answer: Jaundice which develops on the day of delivery
Explanation:Jaundice that appears within the first 24 hours after delivery is always considered to be pathological. Physiological jaundice typically develops 2-3 days after delivery and should resolve within 14 days. The risk of developing jaundice is higher in pre-term infants. In cases of physiological jaundice, bilirubin levels typically do not exceed 200 μmol/L.
Jaundice in newborns can occur within the first 24 hours of life and is always considered pathological. The causes of jaundice during this period include rhesus and ABO haemolytic diseases, hereditary spherocytosis, and glucose-6-phosphodehydrogenase deficiency. On the other hand, jaundice in neonates from 2-14 days is common and usually physiological, affecting up to 40% of babies. This type of jaundice is due to a combination of factors such as more red blood cells, fragile red blood cells, and less developed liver function. Breastfed babies are more likely to develop this type of jaundice.
If jaundice persists after 14 days (21 days for premature babies), a prolonged jaundice screen is performed. This includes tests for conjugated and unconjugated bilirubin, direct antiglobulin test, thyroid function tests, full blood count and blood film, urine for MC&S and reducing sugars, and urea and electrolytes. Prolonged jaundice can be caused by biliary atresia, hypothyroidism, galactosaemia, urinary tract infection, breast milk jaundice, prematurity, and congenital infections such as CMV and toxoplasmosis. Breast milk jaundice is more common in breastfed babies and is thought to be due to high concentrations of beta-glucuronidase, which increases the intestinal absorption of unconjugated bilirubin. Prematurity also increases the risk of kernicterus.

A 7-year-old girl presents to you with her father. She complains of bilateral knee and calf pain at night for the past 6 months. The pain worsens after playing soccer during the day and can cause her to wake up 1-2 times per month. Knee examination is normal, and she is otherwise healthy. What is the most probable diagnosis?
Your Answer: Growing pains
Explanation:Children between the ages of 3 and 12 often experience growing pains, which typically involve leg pain. However, it is crucial to check for any potential warning signs when examining these children. One such warning sign is osteosarcoma, a rare but significant diagnosis that should be ruled out. Symptoms of osteosarcoma include an inexplicable lump, bone pain, or swelling. Another condition to consider is juvenile rheumatoid arthritis, which typically presents with fever, rash, and symmetrical joint pain and swelling.
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 with no 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.

Whilst discussing common causes of respiratory infections with a group of medical students, a question was raised about the age at which croup is typically diagnosed. Specifically, the student asked at what age croup is most commonly diagnosed.
Your Answer: 6 months - 3 years
Explanation:Croup affects 6 months to 3 years old and is caused by parainfluenza virus, while bronchiolitis affects 1-9 month olds and is caused by respiratory syncytial virus. Neonatal respiratory distress can occur due to prematurity.
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.

You are conducting the eight-week baby check on a healthy infant who was born at term. As part of health promotion, you are discussing ways to minimize the risk of Sudden Infant Death Syndrome (SIDS) with the mother. She is already aware of the significance of placing the baby on its back while sleeping and does not smoke. What is the most crucial additional risk factor for SIDS?
Your Answer: Sleeping in the same bed as the baby
Explanation:Studies have indicated that bed sharing is the most prominent risk factor for SIDS, followed by prone sleeping, parental smoking, hyperthermia and head covering, and prematurity.
Understanding Sudden Infant Death Syndrome
Sudden infant death syndrome (SIDS) is the leading cause of death in infants during their first year of life, with the highest incidence occurring at three months of age. There are several major risk factors associated with SIDS, including placing the baby to sleep on their stomach, parental smoking, prematurity, bed sharing, and hyperthermia or head covering. These risk factors are additive, meaning that the more risk factors present, the higher the likelihood of SIDS. Other risk factors include male sex, multiple births, lower social classes, maternal drug use, and an increased incidence during winter.
However, there are also protective factors that can reduce the risk of SIDS. Breastfeeding, room sharing (but not bed sharing), and the use of pacifiers have been shown to be protective. In the event of a SIDS occurrence, it is important to screen siblings for potential sepsis and inborn errors of metabolism.
Overall, understanding the risk factors and protective factors associated with SIDS can help parents and caregivers take steps to reduce the likelihood of this tragic event. By following safe sleep practices and promoting healthy habits, we can work towards reducing the incidence of SIDS.

A 5-year-old girl is brought to the emergency room by her father. She has been lethargic and feverish for the past 2 hours. While waiting to be seen, she becomes unconscious. A physician performs an urgent evaluation while the nurse contacts 911. The child is not breathing, so 5 rescue breaths are administered. As you enter the room, the physician cannot detect a pulse in the brachial or carotid artery. What is the best course of action?
Your Answer: Start chest compressions/ventilations at a ratio of 15:2
Explanation:The chest compressions to ventilations ratio should be 15:2 when two trained staff members are present.
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.

Which of the following causes Scarlet fever?
Your Answer: Streptococcus species (group A haemolytic)
Explanation:Scarlet Fever: Symptoms, Causes, and Treatment
Scarlet fever is a bacterial infection caused by toxin-producing strains of the group A streptococcal bacterium (Streptococcus pyogenes). It is a notifiable disease to Public Health England. The symptoms include a sore throat, fever, and a rash with a red strawberry tongue, cervical lymphadenopathy, fine papular rash, tonsillitis, tiredness, headache, nausea, and vomiting.
The condition is treated with fluids, an antipyretic, and phenoxymethylpenicillin. Other causes such as Influenza pneumoniae, Escherichia coli, Haemophilus influenzae, and Parvovirus B19 are not related to scarlet fever. It is important to seek medical attention if you suspect you or your child has scarlet fever.

A 3-year-old boy is taken to his pediatrician by his father due to constant scratching of his bottom at night. The father reports observing some unusual white particles when cleaning his son's bottom after a bowel movement. What would be the best course of action for management?
Your Answer: Prescribe a single dose of mebendazole for the whole household and issue hygiene advice.
Explanation: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 9-month-old girl is presented to the clinic. About 5 days ago, she became feverish after being fussy the day before. The fever subsided after approximately 3 days, but she developed a rash afterwards, which prompted her mother to bring her to the clinic. She is consuming about 80% of her usual feeds, has wet nappies, and has had three instances of loose stools. On examination, she is alert, has a temperature of 37.2ºC, and has clear lungs and unremarkable ears/throat. There are several blanching, rose pink macules on her trunk. What is the most probable diagnosis?
Your Answer: Roseola infantum
Explanation:Roseola infantum is a condition characterized by the occurrence of a fever, which is later followed by the appearance of a rash.
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 6-week-old infant is brought to the GP clinic by her mother for a check-up. The mother is concerned about her daughter's occasional fever and wants to have her checked. The baby appears active and healthy, breathing comfortably with a central capillary refill of less than 2 seconds. She has no rashes and is of normal color.
The following observations and growth measurements are recorded:
- Heart rate: 140 beats per minute (normal range: 115-180)
- Oxygen saturation: 99% on room air
- Respiratory rate: 42 breaths per minute (normal range: 25-60)
- Temperature: 38.7ºC
- Weight: 75th percentile
- Height: 50th percentile
- Head circumference: 75th percentile
What would be the most appropriate course of action?Your Answer: Reassure, give warning signs of when to return, review in 48 hours
Correct Answer: Refer to the paediatric emergency department
Explanation:If an infant is under 3 months old and has a fever over 38ºC, it is crucial to consider the possibility of a serious infection. In this case, it is not appropriate to assess the infant in a GP clinic. Instead, they should be immediately referred to a paediatric emergency department for monitoring and potential investigations, such as urine, chest X-ray, blood cultures, or lumbar puncture, depending on the progression of symptoms. Keeping the infant in the GP clinic for observations is not recommended, as they may deteriorate rapidly and become difficult to manage in that setting. Reassurance and review are usually appropriate for a febrile infant with an obvious infective focus, but not for an infant under 3 months old with no apparent focus of infection. Similarly, an urgent referral to an outpatient paediatrician is not appropriate, as it may take too long to organise and may not be able to manage sudden deterioration.
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 infra-red tympanic thermometer.
The risk stratification table includes green for low risk, amber for intermediate risk, and red for high risk. 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 10-year-old boy is being seen in the paediatric asthma clinic for a review of his asthma. He was diagnosed with asthma 6 months ago and has been using a salbutamol 100mcg metered dose inhaler with a spacer. According to his mother, he has been using his inhaler about 4 times a week and has had 1 episode of waking up at night with difficulty breathing. There have been no recent respiratory infections or changes in his environment. On examination, he appears to be in good health. His inhaler technique is satisfactory. Do you recommend any changes to his asthma medication?
Your Answer: Paediatric low-dose ICS plus a long-acting beta agonist (LABA)
Correct Answer: Paediatric low-dose ICS
Explanation: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.

What is a cause of acyanotic congenital heart disease?
Your Answer: Coarctation of the aorta
Explanation:Coarctation of the aorta does not cause cyanosis.
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.

A mother brings her 5-year-old son to the clinic as she is worried about his bedwetting habit. Unlike his older sibling who stopped bedwetting at the age of 4, this child still wets the bed at night. The mother is seeking advice on possible treatment options. What is the best course of action to manage this issue?
Your Answer: Reassurance and advice on fluid intake, diet and toileting behaviour
Explanation:Reassurance and advice are sufficient for managing nocturnal enuresis in children under 5 years of age. It is important to reassure mothers that bedwetting is still common at the age of 4.
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 grandfather visits you as his grandson has been diagnosed with hypospadias. He wants to know what treatment options are available and if there are any measures he can take to prevent the condition from worsening.
Your Answer: Corrective surgery at around 3 years of age is required and children should not be circumcised
Correct Answer: Corrective surgery at around 12 months of age is required and children should not be circumcised
Explanation:The usual age for performing hypospadias surgery is approximately 12 months.
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 requested to assess a premature infant born at 34 weeks, 48 hours after delivery without any complications. During the examination, you observe a continuous 'machinery-like' murmur and a left subclavicular thrill. Additionally, you notice a bounding pulse and a widened pulse pressure. There are no indications of cyanosis or crackles on auscultation. The mother confirms that there were no complications during pregnancy, and antenatal scans and screening did not reveal any abnormalities. There is no family history of significant illnesses. What would be the most appropriate management option for this probable diagnosis?
Your Answer: Give prostaglandin E1 to the neonate
Correct Answer: Give indomethacin to the neonate
Explanation:To promote closure of patent ductus arteriosus (PDA), indomethacin or ibuprofen is administered to the neonate. This is the correct course of action based on the examination findings. The ductus arteriosus typically closes naturally with the first breaths, but if it remains open, prostaglandin synthesis can be inhibited with medication. Administering indomethacin to the mother would not be effective. Prostaglandin would have the opposite effect and maintain the PDA’s patency, which is not desirable in this scenario. Involving surgeons or monitoring the baby without treatment would also not be appropriate. If left untreated, PDA can lead to serious complications such as pulmonary hypertension or Eisenmenger’s syndrome.
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 10-year-old child receives primary immunisation against hepatitis B. What should be checked four months later to ensure an adequate response to immunisation?
Your Answer: Anti-HBs
Explanation:While a minimum of 10 mIU/ml is considered sufficient to provide protection against infection, it is recommended to attain anti-HBs levels exceeding 100 mIU/ml.
Interpreting hepatitis B serology is an important skill that is still tested in medical exams. It is crucial to keep in mind a few key points. The surface antigen (HBsAg) is the first marker to appear and triggers the production of anti-HBs. If HBsAg is present for more than six months, it indicates chronic disease, while its presence for one to six months implies acute disease. Anti-HBs indicates immunity, either through exposure or immunization, and is negative in chronic disease. Anti-HBc indicates previous or current infection, with IgM anti-HBc appearing during acute or recent hepatitis B infection and persisting IgG anti-HBc. HbeAg is a marker of infectivity and HBV replication.
To illustrate, if someone has been previously immunized, their anti-HBs will be positive, while all other markers will be negative. If they had hepatitis B more than six months ago but are not a carrier, their anti-HBc will be positive, and HBsAg will be negative. However, if they are now a carrier, both anti-HBc and HBsAg will be positive. If HBsAg is present, it indicates an ongoing infection, either acute or chronic if present for more than six months. On the other hand, anti-HBc indicates that the person has caught the virus, and it will be negative if they have been immunized.

A mother brings in her 2-day-old baby girl to the GP surgery. She expresses concern about some white discharge from the baby's vagina. Upon examination, a small amount of mucoid white discharge is observed at the entrance of the vagina. The external appearance of the genitalia is otherwise normal. What is the recommended next step in management?
Your Answer: Reassure the mother that it is normal at this age
Explanation:It is common for newborn girls to experience a mucoid white vaginal discharge, which typically resolves by the age of 3 months. Reassurance is the most suitable course of action, and there is no need to refer to paediatrics or suspect sexual abuse. Arranging a transvaginal ultrasound for these symptoms is not necessary.
Gynaecological Problems in Children
In children, gynaecological problems are not uncommon. However, it is important to note that vaginal examinations and vaginal swabs should not be performed. Instead, referral to a paediatric gynaecologist is appropriate for persistent problems. One of the most common gynaecological disorders in girls is vulvovaginitis. This condition can be caused by bacterial or fungal organisms and is often associated with poor hygiene, tight clothing, lack of labial fat pads protecting the vaginal orifice, and lack of protective acid secretion found in the reproductive years. In some cases, vulvovaginitis may be a result of sexual abuse, which can present as bloody discharge.
It is important to manage vulvovaginitis appropriately. Advising children about hygiene is crucial, and soothing creams may be useful. Topical antibiotics or antifungals may also be prescribed. In resistant cases, oestrogen cream may be recommended. It is important to note that most newborn girls have some mucoid white vaginal discharge, which usually disappears by three months of age.

A 14-year-old girl arrives at the clinic with her mother. She is asking for the combined oral contraceptive (COC) pill as she has recently started a relationship with a 19-year-old man whom she met at a local coffee shop, but they have not yet engaged in sexual activity. During the consultation, you discuss the age difference, but the mother assures you that she has met the boyfriend and believes he treats her daughter well. Both the girl and her mother insist that they do not want anyone else involved. What is the most appropriate course of action?
Your Answer: Assess using Fraser guidelines + prescribe the COC
Correct Answer: Immediately phone local child protection lead and refer to social services
Explanation:According to the GMC guidelines, sexual intercourse with children below the age of 13 cannot be considered consensual, and therefore, any sexual activity would be classified as rape. In such cases, breaking confidentiality is mandatory.
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.

Which one of the following statements regarding the HPV vaccine is incorrect?
Your Answer: The second dose is given at 3-4 years
Correct Answer: Children who received another live vaccine 2 weeks ago can safely have MMR
Explanation:The MMR Vaccine: Information on Contraindications and Adverse Effects
The Measles, Mumps and Rubella (MMR) vaccine is given to children in the UK twice before they enter primary school. The first dose is administered at 12-15 months, while the second dose is given at 3-4 years old. This vaccine is part of the routine immunisation schedule.
However, there are certain contraindications to the MMR vaccine. Children with severe immunosuppression, allergies to neomycin, or those who have received another live vaccine by injection within four weeks should not receive the MMR vaccine. Pregnant women should also avoid getting vaccinated for at least one month following the MMR vaccine. Additionally, if a child has undergone immunoglobulin therapy within the past three months, there may be no immune response to the measles vaccine if antibodies are present.
While the MMR vaccine is generally safe, there are some adverse effects that may occur. After the first dose of the vaccine, some children may experience malaise, fever, and rash. These symptoms typically occur after 5-10 days and last for around 2-3 days. It is important to be aware of these potential side effects and to consult with a healthcare professional if any concerns arise.

A mother brings her 6-week-old newborn baby to see you. She reports that she has noticed that his belly button is always wet and leaks out yellow fluid. On examination, you note a small, red growth of tissue in the centre of the umbilicus, covered with clear mucus. The child is otherwise well, apyrexial and developing normally.
What is the most probable diagnosis for this infant's condition?Your Answer: Omphalitis
Correct Answer: Umbilical granuloma
Explanation:An umbilical granuloma is a growth of tissue that can occur during the healing process of the umbilicus, typically within the first few weeks of life. It appears as a small, red growth in the center of the umbilicus that may leak clear or yellow fluid. Treatment involves applying salt to the wound or cauterizing the granuloma with silver nitrate if necessary.
Omphalitis, also known as umbilical cellulitis, is a bacterial infection that affects the umbilical stump. It typically presents as a superficial cellulitis a few days after birth.
Umbilical hernias are common in newborns, occurring in approximately 1 in 5 children. They usually resolve on their own by the age of 2.
The umbilicus has two arteries and one vein during development, which later dessicates and separates after birth. Umbilical hernias are common in neonates and may resolve spontaneously. Paraumbilical hernias have more defined edges and are less likely to resolve on their own. Omphalitis is a potentially serious infection of the umbilicus that requires antibiotics. Umbilical granulomas can be treated with silver nitrate. Persistent urachus and vitello-intestinal ducts are rare conditions that require imaging and surgical closure.

What is a contraindication for receiving the pneumococcal vaccine in individuals under the age of 2?
Your Answer: Splenectomy in past
Correct Answer: Current febrile illness
Explanation:Immunisation is the process of administering vaccines to protect individuals from infectious diseases. The Department of Health has provided guidance on the safe administration of vaccines in its publication ‘Immunisation against infectious disease’ in 2006. The guidance outlines general contraindications to immunisation, such as confirmed anaphylactic reactions to previous doses of a vaccine containing the same antigens or another component contained in the relevant vaccine. Vaccines should also be delayed in cases of febrile illness or intercurrent infection. Live vaccines should not be administered to pregnant women or individuals with immunosuppression.
Specific vaccines may have their own contraindications, such as deferring DTP vaccination in children with an evolving or unstable neurological condition. However, there are no contraindications to immunisation for individuals with asthma or eczema, a history of seizures (unless associated with fever), or a family history of autism. Additionally, previous natural infections with pertussis, measles, mumps, or rubella do not preclude immunisation. Other factors such as neurological conditions like Down’s or cerebral palsy, low birth weight or prematurity, and patients on replacement steroids (e.g. CAH) also do not contraindicate immunisation.

A father brings his 18-month-old son in for review. He started walking five months ago. The father has noticed that his son seems to be 'bow-legged' when he walks.
Examination of the knees and hips is unremarkable with a full range of movement. Leg length is equal. On standing the intercondylar distance is around 7cm.
What is the most appropriate action?Your Answer: Refer to paediatric orthopaedics
Correct Answer: Reassure that it is a normal variant and likely to resolve by the age of 4 years
Explanation:It is common for children under the age of 3 to have bow legs, which is considered a normal variation. Typically, this condition resolves on its own by the time the child reaches 4 years old.
Common Lower Limb Variants in Children
Parents often become concerned when they notice apparent abnormalities in their child’s lower limbs. This can lead to a visit to their primary care physician and a referral to secondary care. However, many of these presentations are actually normal variants that will resolve on their own.
One common variant is flat feet, where the child’s medial arch is absent when standing. This typically resolves between the ages of 4-8 years and does not require orthotics. In-toeing is another common presentation, which can be caused by metatarsus adductus, internal tibial torsion, or femoral anteversion. Most cases resolve spontaneously, but severe or persistent cases may require intervention. Out-toeing is also common in early infancy and usually resolves by the age of 2 years.
Bow legs, or genu varum, is another normal variant that presents in the first or second year of life. This is characterized by an increased intercondylar distance and typically resolves by the age of 4-5 years. Knock knees, or genu valgum, presents in the third or fourth year of life and is characterized by an increased intermalleolar distance. This also typically resolves spontaneously.
Overall, it is important for parents to be aware of these common lower limb variants in children and to seek medical advice if they have concerns. However, in many cases, parental reassurance and monitoring is all that is needed.

A 14-year-old patient presents to the emergency department with a cut sustained while helping her mother with gardening. The wound appears superficial and is closed with skin glue. During examination, her vital signs are recorded as a temperature of 36.9ºC, heart rate of 86 bpm, blood pressure of 115/87 mmHg, respiratory rate of 16/min, and oxygen saturation of 98% on room air. The patient's mother is concerned about the need for a tetanus booster as she cannot recall if her daughter received the full course of vaccinations during childhood. How should the patient be managed?
Your Answer: Tetanus booster vaccine and immunoglobulin
Explanation:If a patient’s tetanus vaccination history is uncertain and the wound is not minor and less than 6 hours old, they should receive a booster vaccine and immunoglobulin. In this case, the patient is 13 years old and should have received 4 or 5 vaccinations against tetanus under the standard UK vaccination schedule. Antibiotics are not necessary if the wound is clean and not deep. It is more efficient to administer the booster while the patient is in the department rather than asking the GP to follow up, which could result in the patient being lost to follow up. The term tetanus level is incorrect as there is no such test.
Tetanus Vaccination and Management of Wounds
The tetanus vaccine is a purified toxin that is given as part of a combined vaccine. In the UK, it is given as part of the routine immunisation schedule at 2, 3, and 4 months, 3-5 years, and 13-18 years, providing a total of 5 doses for long-term protection against tetanus.
When managing wounds, the first step is to classify them as clean, tetanus-prone, or high-risk tetanus-prone. Clean wounds are less than 6 hours old and have negligible tissue damage, while tetanus-prone wounds include puncture-type injuries acquired in a contaminated environment or wounds containing foreign bodies. High-risk tetanus-prone wounds include wounds or burns with systemic sepsis, certain animal bites and scratches, heavy contamination with material likely to contain tetanus spores, wounds or burns with extensive devitalised tissue, and wounds or burns that require surgical intervention.
If the patient has had a full course of tetanus vaccines with the last dose less than 10 years ago, no vaccine or tetanus immunoglobulin is required regardless of the wound severity. If the patient has had a full course of tetanus vaccines with the last dose more than 10 years ago, a reinforcing dose of vaccine is required for tetanus-prone wounds, and a reinforcing dose of vaccine plus tetanus immunoglobulin is required for high-risk wounds. If the vaccination history is incomplete or unknown, a reinforcing dose of vaccine is required regardless of the wound severity, and a reinforcing dose of vaccine plus tetanus immunoglobulin is required for tetanus-prone and high-risk wounds.
Overall, proper vaccination and wound management are crucial in preventing tetanus infection.

A 16-year-old girl comes to see her doctor because she has not yet begun menstruating. During the physical examination, you observe that she has a short stature and a webbed neck. What would you anticipate hearing when listening to her heart?
Your Answer: Ejection systolic murmur
Explanation:The ejection systolic murmur present in this patient is likely due to her Turner’s syndrome, which is associated with a bicuspid aortic valve. A continuous machinery murmur, late systolic murmur, and mid-late diastolic murmur are less likely causes, as they are associated with different conditions that are not commonly seen in patients 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 newborn is delivered at term via vaginal delivery with no complications, however she is not showing signs of breathing at one minute. Her heart rate is >110bpm, but she is floppy and has a blue colouration. What is the most appropriate next step?
Your Answer: 5 breaths of air via face mask
Explanation:Performing airway suction should be avoided unless there is clear evidence of thick meconium causing obstruction, as it may lead to reflex bradycardia in infants. Chest compressions are not necessary if the heart rate (HR) is above 100 beats per minute (bpm). CPR should only be initiated if the HR drops below 60 bpm. If there are no signs of breathing due to fluid in the lungs, administering five breaths through a 250ml ambu bag is a more effective and hygienic approach than using mouth-to-mouth resuscitation in a hospital setting.
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 22-month-old toddler presents to the GP with a barking cough and fever for 3 days. The fever has been responding to regular paracetamol. The child's parent reports that the toddler is eating and drinking normally and has been urinating regularly. During playtime, the parent has noticed some increased breathing sounds, but they disappear when the child is at rest. There have been no febrile convulsions, rash, or drowsiness reported.
Upon examination, the toddler has a clear chest with no signs of increased work of breathing. An occasional barking cough is heard.
What is the most appropriate management for this toddler?Your Answer: Oral dexamethasone
Explanation:For this infant with mild croup, the recommended treatment is a single dose of oral dexamethasone (0.15 mg/kg body weight) regardless of the severity of symptoms. This should be taken immediately to reduce upper airway inflammation and alleviate the occasional barking cough and stridor. Delayed antibiotic prescription, immediate oral antibiotics, humidified oxygen, and inhaled or nebulised salbutamol are not appropriate options for croup management. Antibiotics are ineffective against viruses, which are the most common cause of croup, while humidified oxygen and inhaled or nebulised salbutamol are used for other respiratory conditions.
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.

Question 45

As a foundation doctor on the neonatal ward, you consult with your supervisor regarding a patient who is five days old and displaying symptoms of cyanosis, tachypnoea, and weak peripheral pulses. Your suspicion is that the patient has a duct dependent cardiac lesion. Once this is confirmed, what would be the most suitable course of treatment?
Your Answer: Indomethacin
Correct Answer: Prostaglandins
Explanation:Prostaglandins can maintain the patency of a patent ductus arteriosus, which can be beneficial in cases of duct dependent cardiac lesions such as tetralogy of Fallot, Ebstein’s anomaly, pulmonary atresia, and pulmonary stenosis. These conditions may be diagnosed before birth or present with symptoms such as cyanosis, tachypnea, and weak peripheral pulses at birth. While surgery is often the definitive treatment, keeping the duct open with prostaglandins can provide time for appropriate management planning. Aspirin is not recommended for children due to the risk of Reyes syndrome, which can cause liver and brain edema and be fatal. Indomethacin and other medications may also be used to close 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 6-week-old infant presents to the clinic with a red rash on their scalp accompanied by yellow flakes. What is the probable diagnosis?
Your Answer: Seborrhoeic dermatitis
Explanation:Seborrhoeic Dermatitis in Children: Symptoms and Management
Seborrhoeic dermatitis is a common skin condition that affects children, typically appearing on the scalp, nappy area, face, and limb flexures. One of the earliest signs is cradle cap, which can develop in the first few weeks of life. This condition is characterized by a red rash with coarse yellow scales.
Fortunately, seborrhoeic dermatitis in children is not harmful and usually resolves within a few weeks. Parents can help manage the condition by massaging a topical emollient onto the scalp to loosen scales, brushing gently with a soft brush, and washing off with shampoo. If the condition is severe or persistent, a topical imidazole cream may be prescribed.
It’s important to note that seborrhoeic dermatitis in children tends to resolve spontaneously by around 8 months of age. Parents should not be overly concerned and can take comfort in knowing that this condition is common and easily managed. By following these simple steps, parents can help their child feel more comfortable and alleviate any discomfort associated with seborrhoeic dermatitis.

A 9-year-old girl comes to the clinic with a one-month history of unusual facial movements noticed by her father. Her father reports that he first noticed her having twitching of left eye and face as well as drooling of saliva. This happens about twice a week, always at night. Each episode lasts for 1-2 minutes and after each episode, the girl is unable to speak properly for around 5 minutes. The girl is aware of these occurrences but reports unable to control them. The father reports that his daughter is otherwise normal with normal development.
What is the diagnosis?Your Answer: Benign rolandic epilepsy
Explanation:Benign rolandic epilepsy is identified by the occurrence of partial seizures during the night.
The child displays typical indications of benign rolandic epilepsy, which is distinguished by partial seizures that occur during the night. Reflex anoxic seizures are caused by anoxia and typically manifest as syncope and subsequent convulsions in very young children. Panayiotopoulos syndrome is characterised by seizures, often prolonged, with predominantly autonomic symptoms such as nausea and retching. Idiopathic childhood occipital epilepsy of Gastaut is mainly characterised by visual hallucinations. Night terrors are a sleep disorder that causes feelings of dread or terror, typically during REM sleep.
Benign rolandic epilepsy is a type of epilepsy that usually affects children between the ages of 4 and 12 years. This condition is characterized by seizures that typically occur at night and are often partial, causing sensations in the face. However, these seizures may also progress to involve the entire body. Despite these symptoms, children with benign rolandic epilepsy are otherwise healthy and normal.
Diagnosis of benign rolandic epilepsy is typically confirmed through an electroencephalogram (EEG), which shows characteristic centrotemporal spikes. Fortunately, the prognosis for this condition is excellent, with seizures typically ceasing by adolescence. While the symptoms of benign rolandic epilepsy can be concerning for parents and caregivers, it is important to remember that this condition is generally not associated with any long-term complications or developmental delays.

You are consulted by the parents of a 5-year-old girl. She has a lifelong history of bedwetting at night, and they are becoming increasingly concerned that the problem is not getting any better. She never has accidents in the day and opens her bowels at least once a day. She has been potty-trained since the age of two. Apart from hay fever, there is no relevant family history. Physical examination is normal. Urinalysis reveals no abnormality. Things have come to a head as she is starting school in two weeks’ time, and they do not want her to wet the bed.
What is the most appropriate management plan?Your Answer: Give general advice on enuresis, reassure the parents that he is almost certain to grow out of the problem and commence treatment with an enuresis alarm to prepare him for his camping trip and advise to restrict fluid from 1600 h to prevent bedwetting during the camping trip
Correct Answer: Give general advice on enuresis, reassure the parents that he is almost certain to grow out of the problem and prescribe desmopressin to be taken during the camping trip to prevent bedwetting
Explanation:Managing Primary Enuresis in Children: Advice and Treatment Options
Primary enuresis, or bedwetting, is a common condition affecting 15-20% of children. It is characterized by nocturnal wetting without daytime symptoms and is thought to be caused by bladder dysfunction. Parents of children with primary enuresis may be reassured that their child is likely to grow out of the problem by age 15, with only 1% of patients continuing to have symptoms into adulthood.
Treatment options for primary enuresis include the use of an enuresis alarm combined with a reward system to teach and reward good habits. Fluid should not be restricted. In children over the age of 5, short-term control can be achieved with a prescription of desmopressin to prevent enuresis during sleepovers or school trips.
It is important to involve the child in the management plan and explore family habits. Referral to a paediatric urologist may be necessary for children with primary enuresis and daytime symptoms or for those who have failed two complete courses of treatment with an enuresis alarm or desmopressin.

As a foundation doctor on the neonatal ward, you are updating a prescription chart for a premature baby born at twenty-seven weeks who is in poor condition. While reviewing the chart, you come across caffeine as one of the medications prescribed. Can you explain the purpose of caffeine in neonatal care?
Your Answer: Aiding weaning off a ventilator
Explanation:Newborn babies can benefit from caffeine as it acts as a respiratory stimulant. It is also used to help neonates transition off a ventilator. Sildenafil, known as Viagra, is typically used to treat erectile dysfunction in adults, but it can also be used to treat pulmonary hypertension in neonates. The approach to addressing distress in newborns depends on the underlying cause, which is often related to respiratory or pain issues. Gaviscon and ranitidine are sometimes used to treat gastro-oesophageal reflux, although this is not an approved use. Necrotising enterocolitis is more prevalent in premature babies and can be treated through medical interventions, such as resting the gut, or surgical interventions, such as resection.
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.

What is a not a cause of hypertension in adolescents?
Your Answer: Renal parenchymal disease
Correct Answer: Bartter's syndrome
Explanation:Bartter’s syndrome is a genetic condition that typically follows an autosomal recessive pattern of inheritance. It results in severe hypokalaemia due to a defect in the absorption of chloride at the Na+ K+ 2Cl- cotransporter in the ascending loop of Henle. Unlike other endocrine causes of hypokalaemia such as Conn’s, Cushing’s and Liddle’s syndrome, Bartter’s syndrome is associated with normotension. The condition usually presents in childhood and is characterized by symptoms such as failure to thrive, polyuria, polydipsia, hypokalaemia, and weakness.
Hypertension, or high blood pressure, can also affect children. To measure blood pressure in children, it is important to use a cuff size that is approximately 2/3 the length of their upper arm. The 4th Korotkoff sound is used to measure diastolic blood pressure until adolescence, when the 5th Korotkoff sound can be used. Results should be compared with a graph of normal values for their age.
In younger children, secondary hypertension is the most common cause, with renal parenchymal disease accounting for up to 80% of cases. Other causes of hypertension in children include renal vascular disease, coarctation of the aorta, phaeochromocytoma, congenital adrenal hyperplasia, and essential or primary hypertension, which becomes more common as children get older. It is important to identify the underlying cause of hypertension in children in order to provide appropriate treatment and prevent complications.

As a foundation doctor on the neonatal ward, you conduct a newborn examination on a six hour old infant. The baby was delivered vaginally at 38 weeks with no risk factors for sepsis and no maternal concerns. The baby was born in a healthy condition, with good tone. However, you observe cyanosis in the peripheries, while the rest of the examination appears normal. Pre and post ductal oxygen saturations are at 97%. What is the probable diagnosis?
Your Answer: Sepsis
Correct Answer: Acrocyanosis
Explanation: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 6-year-old girl presents to the emergency department with a 5-day history of fever and lethargy. She has no significant medical history and is up to date with her childhood vaccinations.
During the examination, the girl appears drowsy and has a temperature of 39.2ºC. Her heart rate is 155 beats/min and respiratory rate is 46 breaths/min. She has a maculopapular rash on her torso and upper limbs, and her lips are cracked and erythematous. Additionally, her conjunctivae are inflamed. Kernig's sign is negative.
What is the most appropriate management for this patient, given the likely diagnosis?Your Answer: Oral phenoxymethylpenicillin
Correct Answer: Aspirin
Explanation:High-dose aspirin therapy is the recommended treatment for Kawasaki disease, despite it typically being contraindicated in children.
Aspirin is the appropriate treatment for this patient’s diagnosis of Kawasaki disease, as evidenced by their persistent fever, conjunctivitis, maculopapular rash, and cracked and erythematous lips. This disease is vasculitic in nature, and current guidelines advise the use of high-dose aspirin therapy as the initial treatment.
Intravenous aciclovir is not indicated for Kawasaki disease, as it is used to treat viral conditions such as viral meningitis or encephalitis.
Intravenous ceftriaxone is not appropriate for the treatment of Kawasaki disease, as it is reserved for significant bacterial infections like Neisseria meningitidis. Additionally, the negative Kernig’s sign makes meningitis less likely.
Oral phenoxymethylpenicillin is not the recommended treatment for Kawasaki disease, as the mucosal changes and conjunctivitis are more indicative of this disease rather than scarlet fever, which is treated with oral phenoxymethylpenicillin.
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 boy is presented to the GP by his mother due to the development of a limp. The mother noticed that his left hip was sore and stiff about a month ago. The pain has gradually worsened, making it difficult for the boy to walk and causing significant discomfort. The boy has a normal developmental history and is otherwise healthy. What is the probable underlying cause of his symptoms?
Your Answer: Epiphyseal slip
Correct Answer: Avascular necrosis
Explanation:Perthes’ disease is characterized by a lack of blood supply to the femoral head, leading to its necrosis and resulting in symptoms such as hip pain, stiffness, and limping. These symptoms are consistent with the presentation of a young boy experiencing progressive hip pain and reduced range of motion. The age of onset for Perthes’ disease typically falls within the range of 6-8 years old, further supporting this diagnosis.
While an epiphyseal plate fracture can also cause pain and limping, it is typically the result of a traumatic injury, which is not the case in this scenario. Slipped upper femoral epiphysis (SUFE) is another potential cause of hip pain and limping, but it typically affects older children and progresses more slowly over several months. Septic arthritis, on the other hand, is a medical emergency characterized by acute joint pain, swelling, and systemic symptoms, which are not present in this case.
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 one of the following is not included in the core Adolescent Health Promotion Program as outlined in the National Service Framework for Children?
Your Answer: Heel-prick test at 5-9 days
Correct Answer: 8-9 month surveillance review
Explanation:The regular surveillance evaluations that were conducted at 8 months, 2 years, and 3-4 years have been discontinued. Nevertheless, if a child is considered to be in a vulnerable situation, it is recommended to conduct more frequent assessments.
Child Health Surveillance in the UK
Child health surveillance in the UK involves a series of checks and tests to ensure the well-being of children from before birth to pre-school age. During the antenatal period, healthcare professionals ensure that the baby is growing properly and check for any maternal infections that may affect the baby. An ultrasound scan is also performed to detect any fetal abnormalities, and blood tests are done to check for neural tube defects.
After birth, a clinical examination of the newborn is conducted, and a hearing screening test is performed. The mother is given a Personal Child Health Record, which contains important information about the child’s health. Within the first month, a heel-prick test is done to check for hypothyroidism, PKU, metabolic diseases, cystic fibrosis, and medium-chain acyl Co-A dehydrogenase deficiency (MCADD). A midwife visit may also be conducted within the first four weeks.
In the following months, health visitor input is provided, and a GP examination is done at 6-8 weeks. Routine immunisations are also given during this time. Ongoing monitoring of growth, vision, and hearing is conducted, and health professionals provide advice on immunisations, diet, and accident prevention.
In pre-school, a national orthoptist-led programme for pre-school vision screening is set to be introduced. Overall, child health surveillance in the UK aims to ensure that children receive the necessary care and attention to promote their health and well-being.

Which one of the following statements regarding congenital inguinal hernias is accurate?
Your Answer: They are more common on the right side
Explanation:Abdominal wall hernias occur when an organ or the fascia of an organ protrudes through the wall of the cavity that normally contains it. Risk factors for developing these hernias include obesity, ascites, increasing age, and surgical wounds. Symptoms of abdominal wall hernias include a palpable lump, cough impulse, pain, obstruction (more common in femoral hernias), and strangulation (which can compromise the bowel blood supply and lead to infarction). There are several types of abdominal wall hernias, including inguinal hernias (which account for 75% of cases and are more common in men), femoral hernias (more common in women and have a high risk of obstruction and strangulation), umbilical hernias (symmetrical bulge under the umbilicus), paraumbilical hernias (asymmetrical bulge), epigastric hernias (lump in the midline between umbilicus and xiphisternum), incisional hernias (which may occur after abdominal surgery), Spigelian hernias (rare and seen in older patients), obturator hernias (more common in females and can cause bowel obstruction), and Richter hernias (a rare type of hernia that can present with strangulation without symptoms of obstruction). In children, congenital inguinal hernias and infantile umbilical hernias are the most common types, with surgical repair recommended for the former and most resolving on their own for the latter.

A mother brings in her 4-year-old daughter to the GP surgery. For the past 3 weeks, the girl has been experiencing discomfort while passing urine. She has a history of 3 previous urinary tract infections. During external examination, you notice thin semitranslucent adhesions that cover the vaginal opening between the labia minora but not the urethra opening. You prescribe a course of trimethoprim. What other treatment options would you consider initiating?
Your Answer: Oral prednisolone
Correct Answer: Oestrogen cream
Explanation:Labial adhesions are typically caused by low levels of estrogen and are usually treated conservatively as they often resolve during puberty. However, if there are recurrent urinary tract infections, oestrogen creams may be considered as a treatment option. The use of trimethoprim pessary, IV dexamethasone, and oral prednisolone are not appropriate treatments for labial adhesions. It is important to address the adhesion as leaving it untreated can lead to complications.
Labial Adhesions: A Common Condition in Young Girls
Labial adhesions refer to the fusion of the labia minora in the middle, which is commonly observed in girls aged between 3 months and 3 years. This condition can be treated conservatively, and spontaneous resolution usually occurs around puberty. It is important to note that labial adhesions are different from an imperforate hymen.
Symptoms of labial adhesions include problems with urination, such as pooling in the vagina. Upon examination, thin semitranslucent adhesions covering the vaginal opening between the labia minora may be seen, which can sometimes cover the vaginal opening completely.
Conservative management is typically appropriate for most cases of labial adhesions. However, if there are associated problems such as recurrent urinary tract infections, oestrogen cream may be tried. If this fails, surgical intervention may be necessary.
In summary, labial adhesions are a common condition in young girls that can be managed conservatively. It is important to seek medical attention if symptoms persist or worsen.

A 6-year-old boy is brought to the Emergency Department by his mother with complaints of right iliac fossa pain for the past two days. He has no previous medical history except for a cough and sore throat in the last week. He has had a high fever for the past two days and has lost his appetite but denies any other symptoms.
On examination, his temperature is 38.9 °C, and his pulse is 130 beats per minute. Bilateral enlarged submandibular and cervical lymph nodes are palpable and slightly tender. Chest examination is clear, with transmitted sounds from the upper airways. Abdominal examination reveals marked tenderness in the right iliac fossa with no guarding.
Urine dipstick reveals 2+ of ketones and 1+ of protein.
Blood test results for his full blood count (FBC) are as follows:
Investigation Result Normal value
Haemoglobin (Hb) 145 g/l 135–175 g/l
White cell count (WCC) 14.3 × 109/ 4.0–11.0 × 109/l
Platelets (PLT) 425 × 109/l 150–400 × 109/l
What is the most likely clinical diagnosis for this 6-year-old boy?Your Answer: Appendicitis
Correct Answer: Mesenteric adenitis
Explanation:Possible Diagnoses for a Child with Right Iliac Fossa Pain and High Temperature
When a child presents with right iliac fossa pain and high temperature, several possible diagnoses should be considered. One of them is mesenteric adenitis, which is characterized by abdominal pain resulting from mesenteric lymphadenopathy and often accompanied by enlarged neck nodes and a recent history of viral upper respiratory tract infection. Appendicitis is another possibility, but it tends to present with a low-grade fever and peritoneal irritation that causes involuntary muscle spasm in the abdominal wall. Meckel’s diverticulitis, which is clinically indistinguishable from appendicitis, is an intra-operative or radiological diagnosis and can cause gastrointestinal bleeding, obstruction, inflammation, or umbilical discharge. Retroperitoneal appendix abscess is an uncommon type of infection that presents with fever, back pain, and abdominal pain, but it can also cause other symptoms such as gastrointestinal bleeding, poor wound healing, chest pain, general discomfort, urinary frequency, and haematuria. Finally, urinary tract infection (UTI) is unlikely if there are no nitrites or leukocytes on urine dipstick, but it can cause non-specific symptoms such as vomiting/diarrhoea, mild abdominal pain, dysuria, frequency, and enuresis, especially in infants.

A 3-year-old child presents to the emergency department with a 3 day history of left knee pain and irritability. The child had recently recovered from a viral respiratory tract infection and is currently asymptomatic and without fever. Upon examination, the joint is painful to move but not hot or red, and the child is able to bear weight. Laboratory results reveal a hemoglobin level of 140 g/L (male: 135-180, female: 115-160), platelet count of 450 * 109/L (150-400), white cell count of 11.5 * 109/L (4.0-11.0), CRP of 29 mg/L (<5), and ESR of 32 mm/hr (0-10). What is the most likely diagnosis?
Your Answer: Osteochondritis dissecans
Correct Answer: Transient synovitis
Explanation:Understanding Septic Arthritis in Children
Septic arthritis is a condition that affects children and can lead to permanent joint damage and systemic infection if not treated promptly. It has an incidence of around 4-5 per 100,000 children and is more common in boys, with a M:F ratio of 2:1. The hip, knee, and ankle are the most commonly affected joints. Symptoms of septic arthritis include joint pain, limp, fever, and lethargy. Signs of the condition include a swollen and red joint, with minimal movement possible.
To diagnose septic arthritis, joint aspiration is necessary to culture the affected area. This will show a raised white blood cell count. Inflammatory markers in the blood will also be raised, and blood cultures will be taken. The Kocher criteria are used to diagnose septic arthritis and include a fever of over 38.5 degrees Celsius, non-weight bearing, raised erythrocyte sedimentation rate (ESR), and raised white cell count (WCC).
Understanding septic arthritis in children is crucial for prompt diagnosis and treatment to reduce the risk of permanent joint damage and systemic infection.

A 9-week-old girl is seen by a surgeon for a general evaluation. During the assessment, her head circumference is observed to be between the 0.4th and 2nd percentile. Which of the following options would NOT account for this observation?
Your Answer: Fragile X syndrome
Explanation:Although not a typical reason for macrocephaly, children diagnosed with Fragile X syndrome often exhibit an enlarged head size.
Understanding Microcephaly: Causes and Definitions
Microcephaly is a condition characterized by a smaller than average head circumference, with measurements falling below the 2nd percentile. While some cases may be attributed to normal variation or familial traits, other causes include congenital infections, perinatal brain injury, fetal alcohol syndrome, and syndromes such as Patau and craniosynostosis.
In some cases, microcephaly may simply be a variation of normal development, with no underlying medical concerns. However, when it is caused by other factors, it can lead to developmental delays, intellectual disability, and other neurological issues.
It is important to note that microcephaly is not a disease in and of itself, but rather a symptom of an underlying condition. As such, it is crucial to identify and address the root cause of microcephaly in order to provide appropriate treatment and support for affected individuals.

Which of the following neonatal complications is least frequently observed in pregnancies of women with diabetes?
Your Answer: Microsomia
Explanation:Macrosomia is more likely to occur in individuals with diabetes than microsomia.
Complications of Diabetes during Pregnancy
Diabetes during pregnancy can lead to various complications for both the mother and the baby. Maternal complications may include polyhydramnios, which occurs in 25% of cases and may be due to fetal polyuria. Preterm labor is also a common complication, occurring in 15% of cases and often associated with polyhydramnios.
Neonatal complications may include macrosomia, although diabetes can also cause small for gestational age babies. Hypoglycemia is another potential complication, which can occur due to beta cell hyperplasia. Respiratory distress syndrome may also occur, as surfactant production is delayed. Polycythemia, which leads to more neonatal jaundice, is also a possibility.
Malformation rates may increase 3-4 fold, with sacral agenesis, CNS and CVS malformations (hypertrophic cardiomyopathy) being some of the potential risks. Stillbirth is also a possibility. Hypomagnesemia and hypocalcemia may occur, and shoulder dystocia may cause Erb’s palsy.

A 6-month-old is brought in by a concerned mother. She reports her baby crying after feeds and drawing his legs to his chest for several weeks. His growth is good and examination unremarkable.
Which of the following is the best treatment option?Your Answer: Gaviscon
Correct Answer: Supportive advice and reassurance
Explanation:Managing Infantile Colic: Supportive Advice and Reassurance
Infantile colic can be a challenging condition for both parents and babies. While there is little evidence for treating colic, there are some strategies that can help manage the symptoms. Nursing the baby upright after feeds, bathing the infant in warm water, using white noise, gentle movement of baby, eg rocking the crib, holding baby during an episode, winding well and offering reassurance when needed can all be helpful.
However, it’s important to note that medications such as Infacol, Colief, Gaviscon, and Ranitidine are not recommended as first-line treatments due to lack of evidence. Maternal diet modification, probiotic supplements, herbal supplements, and manipulative strategies are also not recommended.
If your baby is experiencing colic, know that you are not alone and that supportive advice and reassurance can go a long way in managing the symptoms.

A 6-year-old girl's normal heart rate is which of the following?
Your Answer: 80 – 120 bpm
Explanation:Normal Heart Rate Range for Children
The normal heart rate for a 6-year-old child would be between 80-120 beats per minute (bpm). It’s important to note that the normal heart rate range varies depending on the child’s age. For instance, a heart rate of 110-160 bpm would be normal for a child aged less than 1 year, while a heart rate of 60-100 bpm would be normal for a child aged over 12 years. For children aged between 1 and 2 years, a heart rate of 100-150 bpm is considered normal, while for those aged between 2 and 5 years, a heart rate of 95-140 bpm is normal. For children aged between 5 and 12 years, a heart rate of 80-120 bpm is normal. Knowing the normal heart rate range for children is essential in monitoring their health and detecting any abnormalities.

A father is worried about a swelling he has noticed on his two-day-old baby's head. The baby was delivered using forceps due to a prolonged second stage of labor. Upon examination, there is a swelling in the parietal region that does not cross the suture lines. The doctor informs him that it may take several weeks to resolve. What type of head injury is most likely responsible for this?
Your Answer: Caput succedaneum
Correct Answer: Cephalohaematoma
Explanation: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 2-year-old girl is brought to the GP by her mother due to a new rash. The mother is worried as the rash appeared suddenly just 1 day ago. The child had a cold with a high fever 3 weeks ago, but has since recovered. Apart from that, the child is healthy and active.
During the examination, an erythematous rash is observed on the child's trunk and limbs. The rash does not seem to be causing any itching and disappears when pressure is applied.
What is the most probable diagnosis?Your Answer: Scarlet fever
Correct Answer: Roseola infantum
Explanation:What is the classical history of roseola infantum and how does it differ from other childhood rashes?
Roseola infantum is a common viral illness that typically affects children between 6 months and 2 years of age. It is characterized by a high fever that is followed 1-2 weeks later by an erythematous rash across the trunk and limbs. Febrile seizures are also common with this illness.
Measles, on the other hand, presents with an erythematous rash that starts behind the ears and spreads to the rest of the body. It is associated with fever, conjunctivitis, coryzal symptoms, and white koplik spots on the inside of the mouth.
Parvovirus B19, also known as slapped cheek disease, is characterized by a rash that first appears on the cheeks before spreading to the trunk and arms. It is usually preceded by 2-5 days of mild fever and non-specific viral symptoms.
Rubella presents with an erythematous rash that starts on the face and spreads to the rest of the body. It is associated with mild fever, sore throat, and lymphadenopathy.
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 boy of 7 presents with a unilateral painless limp. Examination shows limitation of rotation and extension at the affected hip joint, and a radiograph shows a dense flattened and fragmented femoral head on the affected side.
Which of the following is the most likely diagnosis?
Your Answer: Congenital dislocation of the hip
Correct Answer: Perthes' disease
Explanation:Perthes’ Disease: Avascular Necrosis of the Proximal Femoral Head in Children
Perthes’ disease is a condition that results from avascular necrosis of the proximal femoral head, which is caused by a compromised blood supply. It typically affects children aged 4-10, with boys being affected more frequently than girls. The disease presents with a painless limp and limited range of motion of the affected hip, followed by hip pain as necrosis develops.
The diagnosis of Perthes’ disease is suspected clinically, and radiographs may be normal initially or show only a non-specific effusion. As the condition progresses, the joint space between the ossified femoral head and acetabulum widens, and narrowing or collapse of the femoral head causes it to appear widened and flattened. Eventually, femoral head collapse may ensue.
Other conditions that may present similarly to Perthes’ disease include slipped upper femoral epiphysis, septic arthritis, juvenile rheumatoid arthritis, and congenital dislocation of the hip. However, each of these conditions has its own unique features and diagnostic criteria.
Overall, Perthes’ disease is a generalised disorder of cartilage development that predisposes children to repeated episodes of infarction in the proximal femoral epiphysis. The most significant factors determining prognosis are onset in the older child, epiphyseal protrusion, extensive involvement of the epiphysis, and arrest of subcapital growth.

A 9-month-old boy is presented to the GP with a 4-week history of rash. He has no significant medical history and is meeting developmental milestones appropriately. He has received all of his scheduled immunizations, has no known allergies, and is feeding and urinating well. Upon examination, there is a symmetrical, poorly defined erythematous rash on his elbows and knees. What is the most probable diagnosis?
Your Answer: Pemphigus vulgaris
Correct Answer: Eczema
Explanation:Atopic eczema commonly appears in children before the age of 2, with symptoms often affecting the face and extensor surfaces of the body. This patient’s visible dermatitis in the extensor aspects of her body suggests a diagnosis of atopic eczema based on clinical presentation. Impetigo, pemphigus vulgaris, and psoriasis are unlikely diagnoses given the patient’s symmetrical dry rash involving the extensor aspects of the limbs.
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 12-month-old boy is brought into morning surgery by a concerned first-time mother. She reports several episodes of her baby crying inconsolably and drawing his legs towards his chest since last night. Today he passed some bright red jelly-like blood in his nappy without any stool.
Which of the following is the likely cause?
Your Answer: Constipation
Correct Answer: Intussusception
Explanation:Understanding Intussusception: A Common Cause of Abdominal Pain in Children
Intussusception is a medical condition where one segment of the bowel invaginates into another, causing obstruction and compromise to the blood supply of that part of the bowel. This can lead to symptoms such as colicky abdominal pains, vomiting, and passing of redcurrant stools. It is a common cause of abdominal pain in children and requires immediate medical attention.
Gastroenteritis, appendicitis, constipation, and volvulus are all conditions that can cause abdominal pain in children, but they are not likely to present with the specific symptoms of intussusception. Any child with suspected intussusception should be admitted to the hospital immediately for further investigation and observation.
Understanding the symptoms and causes of intussusception can help parents and caregivers recognize the condition and seek prompt medical attention for their child.

A 7-year-old girl visits her GP clinic with her mother who is worried about her continued bedwetting at night. They had visited the clinic 4 weeks ago and have seen no improvement despite following general management advice and a basic reward system. The girl is healthy otherwise and has no history of constipation or daytime incontinence. She does not complain of any issues at home or school. Physical examination reveals no abnormalities.
What additional treatment options would you suggest for her?Your Answer: Desmopressin plus oxybutynin
Correct Answer: Enuresis alarm
Explanation:When general management advice has not been effective for nocturnal enuresis, an enuresis alarm is typically the first-line recommendation. This device detects urine moisture and triggers an alarm (either through sound or vibration) to wake the child and prompt them to use the toilet. Enuresis alarms have a high success rate when used consistently, and a review is typically conducted after four weeks to assess progress. Bladder training and retention control training are not recommended by NICE guidelines due to limited evidence and concerns about promoting voiding dysfunction. Desmopressin, a vasopressin analogue that reduces urine production, may be considered if the family is not receptive to or finds an enuresis alarm ineffective. However, an enuresis alarm should be offered first. Desmopressin can provide short-term control, but it can cause hyponatremia. Desmopressin plus oxybutynin may be helpful if there are daytime symptoms or if desmopressin alone does not improve the condition. As not all anticholinergic medications have UK marketing authorization for bedwetting treatment, a healthcare professional with appropriate expertise should manage this combination, often requiring a specialist referral and further investigations.
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 6-month-old infant is presented to the emergency department by their caregiver. The infant is exhibiting a fever, lethargy, and decreased muscle tone. Additionally, a non-blanching rash is observed on the right arm of the infant. What is the best course of treatment?
Your Answer: IV cefuroxime
Correct Answer: IV ceftriaxone
Explanation:For an unwell child with suspected meningitis who is over 3 months old, the recommended initial empirical therapy is IV 3rd generation cephalosporin, such as ceftriaxone. IV cefuroxime, a 2nd generation cephalosporin, is not recommended for this purpose. IV cefotaxime + amoxicillin is recommended for babies at risk of jaundice, but as the child in this case is 4 months old, this is not necessary. IV co-amoxiclav and piperacillin do not provide adequate coverage for meningitis and are not suitable for central nervous system infections.
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 meningococcus 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 16-year-old complains of left knee pain that has been present for the last 4 weeks. No injury history is reported. The pain is located in the front of the joint and is aggravated when ascending or descending stairs. Physical examination reveals no significant findings. What is the probable diagnosis?
Your Answer: Osteoarthritis
Correct Answer: Chondromalacia patellae
Explanation:Common Knee Problems in Children and Young Adults
Knee problems are common in children and young adults, especially those who are active in sports.
Chondromalacia patellae is a condition that is more common in teenage girls. It is characterized by the softening of the cartilage of the patella, which can cause anterior knee pain when walking up and down stairs or rising from prolonged sitting. This condition usually responds well to physiotherapy.Osgood-Schlatter disease, also known as tibial apophysitis, is often seen in sporty teenagers. It causes pain, tenderness, and swelling over the tibial tubercle.
Osteochondritis dissecans can cause pain after exercise, as well as intermittent swelling and locking of the knee.
Patellar subluxation can cause medial knee pain due to lateral subluxation of the patella. The knee may also give way.
Patellar tendonitis is more common in athletic teenage boys. It causes chronic anterior knee pain that worsens after running. On examination, the area below the patella is tender. It is important to note that referred pain may come from hip problems such as slipped upper femoral epiphysis.

As a junior doctor on the postnatal ward, you perform a newborn examination on a twelve-hour-old baby delivered vaginally. During the examination, you observe a scalp swelling that has poorly defined margins and crosses suture lines. The swelling is soft and pitted on pressure. The mother reports that the swelling has been present since birth. What is the probable diagnosis?
Your Answer: Epidural haematoma
Correct Answer: Caput succedaneum
Explanation:Scalp edema known as caput seccedaneum can be identified by its ability to extend beyond the suture lines during examination.
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.

A 7-week-old baby girl comes to her pediatrician with complaints of vomiting and regurgitation after feeding. Her mother also reports that she has been experiencing ongoing issues with diarrhea. The baby appears to be generally fussy, and her mother has noticed some dry patches of skin on the inside of her elbows. The mother mentions that the baby is being fed formula.
Upon examination, the baby appears to be an appropriate size and weight for her age, and the only notable finding is mild eczema in the elbow flexures.
What would be the most suitable course of action at this point?Your Answer: Refer to a paediatrician
Correct Answer: Switch to an extensive hydrolysed formula
Explanation:A baby has been diagnosed with cow’s milk protein intolerance, which is a common condition affecting many infants within the first 3 months of life. The severity of the case is considered mild-moderate, as the baby’s size and weight are appropriate for their age. Primary care can manage this condition initially by switching to an extensive hydrolysed formula. An oral challenge is not recommended, as it is typically reserved for cases with significant diagnostic uncertainty or to determine if a food allergy has resolved. Referral to a paediatrician is not necessary at this stage. If the initial switch to an extensive hydrolysed formula does not alleviate symptoms, an amino acid-based formula can be tried. It is not appropriate to suggest that the mother switch to breastfeeding, as this decision should be respected. Even exclusively breastfed babies can develop cow’s milk protein intolerance, and in those cases, the mother should eliminate cow’s milk from her diet while continuing to breastfeed.
Understanding Cow’s Milk Protein Intolerance/Allergy
Cow’s milk protein intolerance/allergy (CMPI/CMPA) is a condition that affects around 3-6% of children, typically presenting in the first 3 months of life in formula-fed infants. Both immediate and delayed reactions can occur, with CMPA used for immediate reactions and CMPI for mild-moderate delayed reactions. Symptoms include regurgitation, vomiting, diarrhea, urticaria, atopic eczema, colic symptoms, wheeze, chronic cough, and rarely, angioedema and anaphylaxis. Diagnosis is often clinical, with investigations including skin prick/patch testing and total IgE and specific IgE (RAST) for cow’s milk protein.
Management for formula-fed infants includes using extensive hydrolyzed formula (eHF) milk as the first-line replacement formula for mild-moderate symptoms and amino acid-based formula (AAF) for severe CMPA or if no response to eHF. Around 10% of infants are also intolerant to soya milk. For breastfed infants, mothers should eliminate cow’s milk protein from their diet and consider prescribing calcium supplements to prevent deficiency. eHF milk can be used when breastfeeding stops until at least 6 months and up to 12 months of age.
The prognosis for CMPI is usually good, with most children becoming milk tolerant by the age of 3-5 years. However, a challenge is often performed in a hospital setting as anaphylaxis can occur. It is important to refer infants with severe symptoms to a pediatrician for management. Understanding CMPI/CMPA and its management can help parents and healthcare providers provide appropriate care for affected children.

Samantha is a 28-year-old who comes to your GP clinic seeking information about cystic fibrosis. She is in a committed relationship and wants to start a family. Samantha mentions that her partner's family has a history of cystic fibrosis and she wants to know more about it. She has already done some research and knows that cystic fibrosis is caused by mutations in the CF transmembrane conductance regulator gene (CFTR) on chromosome 7. Samantha asks you to explain how cystic fibrosis is inherited.
Can you help her understand the inheritance pattern of cystic fibrosis?Your Answer: Autosomal dominant inheritance
Correct Answer: Autosomal recessive inheritance
Explanation:Cystic fibrosis is a genetic disorder that follows an autosomal recessive pattern of inheritance. The carrier frequency is estimated to be 1 in 25 individuals, while the prevalence of the disease is 1 in 2500 newborns. Having a positive family history is the only known risk factor for CF, and parents should receive appropriate counseling before conception or during pregnancy if they are carriers.
Understanding Cystic Fibrosis and the Organisms that Affect Patients
Cystic fibrosis is a genetic disorder that causes thickened secretions in the lungs and pancreas. This condition is caused by a defect in the cystic fibrosis transmembrane conductance regulator gene (CFTR), which regulates chloride channels. In the UK, 80% of CF cases are due to delta F508 on chromosome 7, and the carrier rate is approximately 1 in 25.
CF patients are susceptible to colonization by certain organisms, including Staphylococcus aureus, Pseudomonas aeruginosa, Burkholderia cepacia, and Aspergillus. These organisms can cause infections and exacerbate symptoms in CF patients. It is important for healthcare providers to monitor and manage these infections to improve patient outcomes. By understanding the genetic basis of CF and the organisms that affect patients, healthcare providers can provide better care for those with this condition.

Sophie is a premature baby (28 weeks) who was born 3 weeks ago. During the past week, she has been experiencing bloody stools, abdominal distension, and poor feeding. Upon physical examination, there is an increase in abdominal size with decreased bowel sounds. An abdominal X-ray reveals asymmetrical bowel loops that are dilated and have bowel wall oedema. What is the probable diagnosis?
Your Answer: Necrotising enterocolitis
Explanation: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.

You encounter the mother of a 9-month-old baby who was born premature (at 30 weeks) and has recently been discharged from hospital after being admitted for 'breathing difficulties'. During the hospital stay, the baby received an injection called palivizumab, but the mother cannot remember the purpose of this medication. Can you explain the medication and its indication?
Your Answer: Macrolide antibiotic used to prevent hospital acquired pneumonia
Correct Answer: Monoclonal antibody used to prevent respiratory syncytial virus (RSV)
Explanation:To prevent respiratory syncytial virus (RSV) in children who are at a higher risk of severe disease, palivizumab, a monoclonal antibody, is administered. Infants who are premature, have lung or heart abnormalities, or are immunocompromised are among those at risk of developing RSV.
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 6-week-old baby is seen in surgery with decreased feeding and a temperature of 38.8°C.
Which of the following is the appropriate action?Your Answer: Advise on antipyretic use
Correct Answer: Refer to the paediatric on-call team
Explanation:Management of Fever in a High-Risk Child
When managing a child with fever, it is important to consider their age and any accompanying symptoms. According to the NICE guideline on ‘Fever in under 5s’, children aged <3 months with a temperature of 38°C are at high risk for serious illness. In such cases, it is recommended to refer the child urgently to a paediatric specialist. Encouraging fluids may be useful, but it should not be relied upon to rule out serious underlying illness. Similarly, antipyretics may be given before the child is seen by the paediatric team, but it is important to consult the NICE guideline for appropriate dosages. Blind prescription of oral antibiotics or IM benzylpenicillin is not recommended without a clear source of infection and discussion with the on-call paediatric team. Therefore, it is crucial to refer high-risk children to the paediatric on-call team for further management.

A first-time mother brings her daughter, Lily, who is 7-months old, to the GP surgery. She is worried about Lily's development as she is still unable to sit without support. However, Lily is able to roll from front to back, sit with back straight if being held, and grasp toys when lying on her back. Can you inform the mother at what age Lily will be able to sit without support?
Your Answer: 13-15 months, refer if not achieved by 18 months
Correct Answer: 7-8 months, refer if not achieved by 12 months
Explanation:If sitting without support is not achieved by 12 months, referral is necessary, although it should typically be achieved by 7-8 months.
Gross Motor Developmental Milestones
Gross motor skills refer to the ability to use large muscles in the body for activities such as crawling, walking, running, and jumping. These skills are essential for a child’s physical development and are achieved through a series of developmental milestones.
At 3 months, a baby should have little or no head lag when pulled to sit and should have good head control when lying on their abdomen. By 6 months, they should be able to lift and grasp their feet when lying on their back, pull themselves to a sitting position, and roll from front to back. At 9 months, they should be able to pull themselves to a standing position and crawl. By 12 months, they should be able to cruise and walk with one hand held. At 18 months, they should be able to walk unsupported and squat to pick up a toy. By 2 years, they should be able to run and walk up and down stairs holding onto a rail. At 3 years, they should be able to ride a tricycle using pedals and walk up stairs without holding onto a rail. By 4 years, they should be able to hop on one leg.It is important to note that while the majority of children crawl on all fours before walking, some children may bottom-shuffle, which is a normal variant that runs in families. These milestones serve as a guide for parents and healthcare professionals to monitor a child’s physical development and identify any potential delays or concerns.

While on your GP placement, you hear a cry for help coming from the reception area. Rushing over, you see a young girl who appears to be around 4 years old collapsed on the floor. Upon checking, you find that there are no signs of life.
What would be your initial course of action in this situation?Your Answer: Precordial thump
Correct Answer: 5 rescue breaths
Explanation:According to the latest Resuscitation Council guidelines for paediatric BLS, the correct initial action when there are no signs of breathing is to give 5 rescue breaths. This is different from the adult algorithm where chest compressions may be done first. Giving 2 rescue breaths initially is incorrect. Chest compressions are given at a ratio of 30:2 if there is only one rescuer and at a ratio of 15:2 if there are multiple rescuers, but only after the initial 5 rescue breaths have been given. It is important to remember that in children, respiratory arrest is more common than cardiac arrest.
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 3 day old infant who was delivered via ventouse presents with a swelling on the left parietal region of the head. The swelling was not present immediately after birth and the baby is otherwise healthy. Upon examination, the swelling does not cross suture lines and the fontanelles and sutures appear normal. What is the probable diagnosis?
Your Answer:
Correct Answer: Cephalohaematoma
Explanation:A cephalohaematoma is a swelling caused by bleeding between the skull and periosteum, typically seen in the parietal region of newborns delivered with instruments. It usually appears 2-3 days after birth and does not cross suture lines, resolving over several weeks.
Caput succadeneum is a common condition in newborns immediately after birth, caused by generalised scalp oedema that crosses suture lines. It is associated with prolonged labour and resolves quickly within a few days.
Subaponeurotic haematoma is a rare and potentially life-threatening condition where bleeding occurs outside the periosteum, causing a fluctuant scalp swelling that is not limited by suture lines.
Craniosynostosis is a rare condition where cranial sutures close prematurely, leading to skull deformities that may be evident at birth and associated with genetic syndromes. The shape of the skull depends on which sutures are involved, and other clinical features include early closure of the anterior fontanelle and a raised ridge along the fused suture.
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.
