You are in a genetics clinic and explaining to a mother and father the reasoning why their son has Prader-Willi syndrome. What is the term we use to describe the mode of inheritance for Prader-Willi syndrome?

Autosomal recessive

Autosomal dominant

Imprinting

Pleiotropy

Variable expressivity

Imprinting - Prader-Willi is an example of imprinting. For this disease to occur, the patient does not receive the gene from their father. The mother’s gene may be normal, but that does not prevent the phenotype occurring. The phenotype consists of learning difficulties, hypotonia, obesity and the urge to eat.

Prader-Willi syndrome if gene deleted from father
Angelman syndrome if gene deleted from mother

You see a 6 week-old baby boy for his routine baby check and note a small, soft, umbilical hernia on examination. What should you do?

Advise parents to tape a coin over the area

Refer for surgery

Refer for ultrasound

Watch and wait

Arrange emergency admission

Watch and wait

Small umbilical hernias are common in babies and tend to resolve by 12 months of age. Parents should be reassured no treatment is usually required but to be aware of the signs of obstruction or strangulation such as vomiting, pain and being unable to push the hernia in - this is rare in infants. Advise the parents to present the child at around 2 years of age if the hernia is still present to arrange referral to a surgeon. Attempts to treat the hernia by strapping or taping things over the area are not helpful and can irritate the skin.

An 8-year-old child is brought into the emergency department after have 5 episodes of bloody diarrhoea. Her parents say that the diarrhoea begun 3 days ago after a barbecue at a friends house but did not turn bloody till today. On examination the child is pyrexial at 38 degrees with diffuse abdominal pain. Blood test are taken which show a thrombocytopenia, raised urea, creatinine and lactate dehydrogenase.

Which of the following organisms has most likely caused this infection?

Escherichia coli

Campylobacter jejuni

Listeria monocytogenes

Norovirus

Giardia lamblia

Escherichia coli

The child is not just showing signs of food poisoning but also early signs of haemolytic uraemic syndrome.

You deliver a baby on the maternity ward. At 2 minutes, the baby’s heart rate is 110bpm, the baby is crying loudly with stimulation and moving all four limbs. The baby is pink but hands and feet are slightly blue and feel cold to the touch. What is the APGAR score?

In this case, the baby scores a 9 as the only point he/she misses is the fact his extremities are blue and cold to the touch. This is not unusual in babies

A 5-year-old girl is brought in to see her GP by her mother complaining of increased frequency of passing urine and dysuria. This has never happened before and she is otherwise well. The GP asks for a urine sample to be given before starting antibiotics. Pending culture results, he decides to prescribe a 3-day course of antibiotics. Which antibiotic would be most appropriate in this case?

Trimethoprim

Amoxicillin

Cefalexin

Nitrofurantoin

Clarithromycin

Trimethoprim

Nitrofurantoin is not licensed for a 3-day course. Amoxicillin resistance is common so it should ideally only be used if the culture and sensitivities show that the organism is sensitive. Cephalosporins should be avoided if more narrow-spectrum antibiotics would work due to the increased risk of MRSA, Clostridium difficile and resistant UTIs.

Which one of the following statements regarding childhood squints is correct?

Amblyopia is a sign of a paralytic squint

Divergent squints are more common than convergent squints

The corneal light reflection test is a suitable screening test

Management of the majority of childhood squints should be done in primary care

A child with a non-paralytic squint would have a degree of double vision

The corneal light reflection test is a suitable screening test

A 7-year-old boy is diagnosed with Attention Deficit Hyperactivity Disorder. What is the most appropriate dietary advice to give to his parents?

Eat a normal balanced diet + avoid artificial colourings

Eat a normal balanced diet + avoid all sugar containing products

Eat a normal balanced diet

Eat a normal balanced diet + take a fatty acid supplement unless having three portion of oily fish per week

Eat a normal balanced diet + take a multivitamin tablet

Eat a normal balanced diet

Unless a food diary has shown a link between diet and behaviour there is no basis for recommending the avoidance of artificial colourings or the use of fatty acid supplements

A 4-year-old boy is brought to the GP by his mother who states that she has noted a ‘barking’ cough a few times every day for the last two days. There has been no change to his appetite and his behaviour has not changed. The GP does not find any abnormalities on examination. Given the likely diagnosis of mild croup, what would be the first-line treatment?

Nebulised adrenaline

Oral benzylpenicillin

Oral dexamethasone

Oral prednisolone

Oral ibuprofen

Oral dexamethasone

CKS recommend giving a single dose of oral dexamethasone (0.15mg/kg) to all children regardless of severity

A 10-month-old boy is brought to surgery. Around 4 days ago he developed a fever after being irritable the previous day. The fever settled after around 3 days but following this he developed a rash, which prompted his mother to bring him to surgery. He is taking around 75% of his normal feeds, is producing wet nappies and has had two episodes of loose stools. On examination he is alert, temperature is 37.0ºC, chest is clear, ears/throat unremarkable. There are a number of blanching, rose pink macules present on his trunk. What is the most likely diagnosis?

Rubella

Chickenpox

Roseola infantum

Pityriasis rosea

Measles

Roseola infantum

Fever followed later by rash

A 3-year-old child is brought to surgery as her mother has noticed that she is ‘cross-eyed’. The corneal light reflection test confirms this. What is the most appropriate management?

Advise that referral to secondary care should be delayed until 5 years of age, when surgery may be contemplated

Refer to ophthalmology

Refer to paediatric physiotherapy for eye movement exercises

Reassure mother that the majority of squints improve with age

Advise the mother to restrict the amount of television she watches

Refer children with a squint immediately to ophthalmology

You see a worried mum with her 6 month old baby boy. She is concerned that his skull shape is not normal. His development and birth have been normal and there are no conditions in the family. On examination his head circumference is at the 40th centile with his height and weight at the 30th centile. His occiput is flattened on the left, his left ear mildly protruding forward and his left forehead more prominent than the right. No other abnormality is detected. What is the most appropriate management? Urgent referral to neurosurgery Suggest buying an infant helmet Arrange an MRI scan Routine referral to community child health clinic Reassurance

Reassurance Plagiocephaly is more common since there have been campaigns to encourage babies to sleep on their back to reduce the risk of sudden infant death syndrome (SIDS). Plagiocephaly is a skull deformity producing unilateral occipital flattening, which pushes the ipsilateral forehead ear forwards producing a 'parrallelogram' appearance. The vast majority improve by age 3-5 due to the adoption of a more upright posture. Turning the cot around may help the child look the other way and take the pressure off the one side. Other simple methods include giving the baby time on their tummy during the day, supervised supported sitting during the day, and moving toys/ mobiles around in the cot to change the focus of attention. Ensure all advice is in line with prevention of SIDS.

A 4-year-old boy was discharged from the hospital six weeks ago after an episode of viral gastroenteritis. He now has 4-5 loose stools each day which has been present for the past four weeks. What is the most likely diagnosis? Coeliac disease Inflammatory bowel disease Secondary bacterial infection Lactose intolerance Clostridium difficile infection

Lactose intolerance Transient lactose intolerance is a common complication of viral gastroenteritis. Removal of lactose from the diet for a few months followed by a gradual reintroduction usually resolves the problem.

You are reviewing a 6-month-old child with suspected bronchiolitis. Which one of the following should prompt a referral to hospital? Oxygen saturations of 96% Lethargy Feeding two-thirds of normal amount Respiratory rate 54 / min Crackles on auscultation

Lethargy SIGN suggested the following criteria for referral to hospital: - Poor feeding ( 70/min - Nasal flaring or grunting - Severe chest wall recession - Cyanosis - Oxygen saturation

A 2-year-old boy with meningococcal septicaemia arrests on the ward. You are the first person to attend. After confirming cardiac arrest and following paediatric BLS protocol, what is the rate you should perform chest compressions at? 140-160 compressions per minute 160-180 compressions per minute 120-140 compressions per minute 100-120 compressions per minute 80-100 compressions per minute

100-120 compressions per minute The UK Resuscitation Council's Paediatric Basic Life Support guideline states that chest compressions for children of all ages must be performed at a rate of 100-120 per minute. Compressions should depress the sternum by at least a third of the depth of the chest.

A 12-year-old girl presents with a two-day history of an itchy rash over her whole body associated with a low-grade pyrexia and is diagnosed with chickenpox. Which one of the following complications is least likely to occur? Disseminated haemorrhagic chickenpox Secondary bacterial infection Encephalitis Dilated cardiomyopathy Pneumonia

Dilated cardiomyopathy is not an established complication of chickenpox, unlike the other four options.

A 2-month-old baby presents with gradually worsening noisy breathing which is especially noticeable when she eats. She is on a lower centile for weight gain and has poor food intake. What is the most likely diagnosis? Congenital subglottic stenosis Laryngomalacia Congenital vocal cord paralysis Croup Adenotonsillar hypertrophy

Laryngomalacia Laryngomalacia is the most common cause of stridor in infants. It occurs due to a floppy epiglottis which folds into the airway on inspiration. This is normally a self-limiting condition, but if the stridor becomes severe with signs of respiratory distress, or if there is failure to thrive (due to poor feeding), then surgery is recommended to improve the airway.

A 8-year-old girl presents to the GP with her mother. She has been experiencing nausea for the last few days with dysuria and increased frequency. Her mother is concerned she may have a urinary tract infection. On examination the girl appears well and observations are stable. Abdominal examination is unremarkable. A clean catch sample is obtained and is positive for leucocytes and nitrites. What is the next step in management? 5 day course antibiotics as per local policy 10 day course co-amoxiclav 3 day course antibiotics as per local policy 7 day course antibiotics as per local policy Reassure illness should resolve within 72 hours

3 day course antibiotics as per local policy

A 9-day-old pre-term neonate stops tolerating his cow's milk feeds given by the nurses in the special care baby unit. He vomited after the most recent feed and the nurse noticed bile in the vomit. Stools are normal consistency but the last stool contained fresh red blood. On examination he is well hydrated but his abdomen is grossly distended and an urgent abdominal x-ray is requested. X-ray shows distended loops of bowel with thickening of the bowel wall. What is the next best step in management? Continue oral feeds, switching to breast milk Commence broad spectrum antibiotics Commence IV fluids Commence IV hydrocortisone Commence erythromycin

Commence broad spectrum antibiotics This scenario describes a case of necrotising enterocolitis. Given the history and examination along with the age and prematurity of the infant, bacterial necrotising enterocolitis is the most likely diagnosis. Due to the seriousness of this, broad spectrum antibiotics must be commenced immediately. Although necrotising enterocolitis is seen more often in bottle fed infants, changing feeds at this stage is futile.

A 9-year-old boy presents to the GP with his father. He has had diarrhoea for the past 3 days with no signs of improvement. He describes the stools as watery but there is no blood or mucus present. The boy also states he has been passing stools around 6 times a day since it began. Other than the diarrhoea, the boy has been clinically well. He is still eating and drinking normally and does not appear dehydrated. His bowel pattern has been regular up until this began. His father mentions a few children in the boy's class have been off with a stomach bug in the last week and wonders if this might be the cause. What is the next step in management in this case? Reassure this should settle within 1-2 weeks and advise to maintain normal oral intake Prescribe loperamide Obtain stool for culture Reassure this should settle within 24 hours and advise to maintain a normal oral intake Prescribe oral broad spectrum antibiotics

Reassure this should settle within 1-2 weeks and advise to maintain normal oral intake Viral gastroenteritis is usually self limiting and should settle within 1-2 weeks. It is also crucial to encourage normal oral intake.

A 4-year-old girl presents to the emergency department at 2pm with her pre-school teacher. While having lunch at 12pm, she began to develop urticaria on her arms and neck and has some facial swelling. Her teacher is concerned because the child beside her was eating a peanut butter sandwich. On examination, the child appears well. She has some swelling below her eyes but the airway is patent. Breathing is normal and there is no audible wheeze. Urticaria is present on the right side of the neck and on the forearms. You decide the most likely explanation is a peanut allergy. What is the next best step in management? IM chlorphenamine IM adrenaline 1:1000 IM adrenaline 1:10,000 Oral chlorphenamine IM hydrocortisone

Oral chlorphenamine The child in this scenario is most likely experiencing an allergic reaction to peanuts. She has urticaria and some facial swelling but is otherwise stable with a patent airway. Given her stability and the length of time she has been experiencing this reaction, it is an allergic reaction rather than anaphylaxis.

Meera brings her 5 year old daughter Reena to the surgery who is being treated for acute lymphoblastic leukaemia (ALL) for review as Reena's classmate has been sent home from school with chickenpox. Reena is asymptomatic currently. Meera is unclear if Reena has suffered with chicken pox previously. What would be the correct management? Admit urgently Send home and come back if symptomatic Prescribe aciclovir Prescribe varicella zoster immunoglobulin Urgent bloods for varicella zoster antibodies

Urgent bloods for varicella zoster antibodies 'People who have had a significant exposure to chickenpox and who are immunocompromised should be tested for varicella-zoster antibody, regardless of their history of chickenpox. Test for varicella-zoster immunoglobulin G (IgG) antibodies in primary care if test results can be available within 2 working days of first exposure. If this is not possible, urgently seek specialist advice because testing in secondary care and/or varicella-zoster immunoglobulin prophylaxis may be needed.'

Which one of the following conditions is not associated with obesity in children? Down's syndrome Hypothyroidism Cushing's syndrome Prader-Willi syndrome Growth hormone excess

You are asked to see a baby on the post-natal ward 10 hours post vaginal delivery. The midwife informs you that the mother was positive for group B streptococcus. On examination you note a yellow discolouration to the skin. What is the next most appropriate action to take? Measure serum bilirubin within 2 hours Measure serum bilirubin within 6 hours Measure bilirubin via transcutaneous bilirubinometer Start empirical phototherapy Reassess after 24 hours of age

Measure serum bilirubin within 2 hours

Which one of the following statements regarding infantile spasms is incorrect? EEG shows hypsarrhythmia in the majority of children Carries a good prognosis More common in male children Typically presents in the first 4 to 8 months Causes characteristic 'salaam' attacks
