Q

A 7-year-old boy is brought in to the GP surgery with an exacerbation of asthma.

On examination he has a bilateral expiratory wheeze but there are no signs of respiratory distress.

His respiratory rate is 24 / min and PEF around 60% of normal.

What is the most appropriate action with regards to steroid therapy?

A

3 days of prednisalone

The 2016 British Thoracic Society guidelines state the following with respect to steroid treatment in children:

Use a dose of 10 mg prednisolone for children under 2 years of age, 20 mg for children aged 2-5 years and 30-40 mg for children >5 years. Those already receiving maintenance steroid tablets

Q

A woman brings her daughter to general practice concerned that she hasn’t started her periods yet. Her daughter is 15 years old.

On general examination, she is in the 9th percentile of height for her age, has short ring fingers, poor breast development, and a high arched palate.

On auscultation of her heart, you note a crescendo-decrescendo murmur on the upper right sternal border which radiates to the carotids.

What is the most likely diagnosis?

What type of murmur is a crescendo-decrescendo murmur?

What is the most likely cause of this murmur?

A

Turner’s syndrome is associated with an ejection systolic murmur due to bicuspid aortic valve

bicuspid aortic valve (15%)

coarctation of the aorta (5-10%)

Q

A 4-year-old boy presents with a 2-day history of passing loose stools and non-bilious vomiting. He has passed 5 loose stools and vomited 2 times over the last 48 hours. No visible mucus or blood seen in the stool, and urine output has not changed according to his mother. He is able to tolerate oral fluid and liquid food.

He has not travelled abroad recently and there are no sick contacts. His vaccination schedule is up-to-date and there are no concerns regarding his growth and development.

On examination, he appears well and is alert and responsive. He has warm extremities and capillary refill time is <2 seconds. His vital signs are normal. Peripheral pulses are strong and regular. There is normal skin turgor and there are no sunken eyes.

How should the patient be managed?

A
  • Introduce oral rehydrating solution (ORS)
  • Do not use antidiarrhoeal medications in children under 5 years old with diarrhoea and vomiting caused by gastroenteritis
  • Discourage the drinking of fruit juices and carbonated drinks, especially in those at increased risk of dehydration [NICE 2009]. Fruit juice without extra water or carbonated drinks has too much sugar in it and this can draw water from the body into the gut, making the child more dehydrated.
  • Do not routinely give antibiotics to children with gastroenteritis [NICE 2009] because treatment is not effective on symptoms and does not prevent complications.

Q

A baby boy is delivered by emergency caesarean section at 42 weeks and 6 days because of fetal tachycardia and thick meconium-stained amniotic fluid.

Intrapartum antibiotics were given as the mother was known to be colonised with group B streptococcus.

The baby is cyanosed and tachypnoeic with chest wall retraction.

Chest X-ray shows patchy infiltrations and atelectasis.

What is the likely diagnosis? (3)
What predisposes babies to it? (3)

A
  • Meconium aspiration syndrome refers to respiratory distress in the newborn as a result of meconium in the trachea.
  • It is more common in post-term deliveries, with rates of up to 44% reported in babies born after 42 weeks.
  • It causes respiratory distress, which can be severe.
  • Higher rates occur where there is a history of maternal hypertension, pre-eclampsia, chorioamnionitis, smoking or substance abuse.

Charlie is a 7 month old baby boy who presents to you with poor weight gain (50th to 10th centile), on examination he has an erythematous, blanching rash over his abdomen, colicky abdominal pain and vomiting after feeds.

He has been breast feeding with top-ups of ‘Aptamil’ formula.

What is the most likely diagnosis?

(3)

A

The correct answer is cows’ milk protein intolerance.

  • Multi-system involvement
  • 7 months would suggest the new introduction of top up feeds which correlates with the symptoms
  • Faltering growth along with the multi-system involvement would suggest cows’ milk protein intolerance

Q

You are called to the postnatal ward to review an 8 hour old baby born by elective caesarian section at 39 weeks gestation.

After reading the case notes you discover the use of maternal labetalol for high blood pressure.

On examination, the baby appears jittery and hypotonic.

What is the most appropriate next step?

What is the diagnosis?

(4)

A

A jittery and hypotonic baby may suggest neonatal hypoglycaemia.

Neonatal abstinence syndrome (also called NAS) is a group of conditions caused when a baby withdraws from certain drugs

The use of maternal labetalol is a risk factor and these babies must have their blood glucose measured.

Neonatal abstinence syndrome may also present in this way and so the use of maternal opiates or illicit drug use in pregnancy should also be ascertained.

An emergency call is put out as a 9-year-old boy has collapsed in the waiting room.

The receptionists have already dialled 999.

He does not respond to stimulation and no signs of respiration can be found after 10 seconds.

There is no obvious foreign body in the mouth.

What is the most appropriate next step?

(3)

A
  • give 5 rescue breaths
  • check for signs of circulation

infants use brachial or femoral pulse, children use femoral pulse

  • 15 chest compressions:2 rescue breaths (see above)
  1. chest compressions should be 100-120/min for both infants and children
  2. depth: depress the lower half of the sternum by 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)
  3. in children: compress the lower half of the sternum
  4. in infants: use a two-thumb encircling technique for chest compression

Q

A baby born at 35 weeks gestations via normal vaginal delivery is found to be irritable 48 hours after birth and suffers a convulsion.

There is no obvious head trauma or swellings.

Which of the cranial injuries is most likely to have occurred?

(3)

A

An intracranial haemorrhage refers to subarachnoid, subdural or intraventricular haemorrhages.

Subarachnoid haemorrhages are common and may cause irritability and even convulsions over the first 2 days of life.

Subdural haemorrhages can occur following the use of forceps.

Intraventricular haemorrhage mostly affects pre-term infants and can be diagnosed by ultrasound examinations.

60
Q

What is this

A

A cephalohaematoma may occur after a spontaneous vaginal delivery or following a trauma from the obstetric forceps or the ventouse.

A haemorrhage results after the presidium is sheared from the parietal bone.

The tense swelling is limited to the outline of the bone. It reduces over a few weeks - months.

Q

You are working in the emergency department when you assess a 6-year-old boy with a broken arm.

As part of your examination, you notice some lacerations on his back.

On questioning, he doesn’t want to talk about it but his mother quickly reassures you this is from him playing with his friends after all, ‘boys will be boys’.

You are suspicious. What do you do?

A

Put the child’s arm in a cast and admit them, then contact child protection

The GMC good medical practice contains guidelines on protecting children and young people.

Within this, they state that ‘you must be open-minded when considering the possible cause of an injury or other signs that may suggest that a child or young person is being abused or neglected.

For example, as part of the differential diagnosis, you should consider whether an uncommon condition, including a genetic condition, might have caused or contributed to the child’s or young persons injury or symptoms.

You must also make sure that the clinical needs of children and young people continue to be met and are not overshadowed by child protection concerns.

76
Q

You are asked to review a neonate with a postnatal diagnosis of congenital diaphragmatic hernia.

They are now stable, having had initial medical management.

The baby’s parents have done some background reading on the condition and have some questions for you.

Q

The next parent arrives with her 2-year-old son.

He was diagnosed with cow’s milk protein allergy (CMPA) when he was 3 months old and got much better after it was first recognised.

He has been on a dairy excluding diet and has been fed hydrolysed milk up until 1 year of age.

He was tried on the milk ladder and successfully made it onto raw milk in the past month without further reaction or diarrhoea.

His mother wonders whether this is normal, or if he was misdiagnosed when he was younger.

IgE testing had been done and found to be normal.

What would you advise the boy’s mother?

A

Most children with non-IgE-mediated cow’s milk protein allergy will be milk tolerant by 3 years of age

84
Q

(2)

A

Most children with non-IgE-mediated cow’s milk protein allergy will be milk tolerant by 3 years of age

Most children with IgE-mediated cow’s milk protein allergy will be milk tolerant by 3 years of age

85
Q

How is cows milk protein (CMPA) generally managed?

(6)

A

Management if formula-fed

  1. extensive hydrolysed formula (eHF) milk is the first-line replacement formula for infants with mild-moderate symptoms
  2. amino acid-based formula (AAF) in infants with severe CMPA or if no response to eHF
  3. around 10% of infants are also intolerant to soya milk

Management if breastfed

  1. continue breastfeeding
  2. eliminate cow’s milk protein from maternal diet. Consider prescribing calcium supplements for breastfeeding mothers whose babies have, or are suspected to have, CMPI, to prevent deficiency whilst they exclude dairy from their diet
  3. use eHF milk when breastfeeding stops, until 12 months of age and at least for 6 months
86

98
Q

A 15-year-old known type 1 diabetic comes in with vomiting, abdominal pain, and drowsiness.

On examination, you notice her breath smells of pear drops.

She tells you that she can’t be admitted right now as she is missing a friend’s birthday party.

After explaining the risks of leaving she seems to understand, can repeat what you have said, and explain her decision.

Her parents say that she should stay for treatment. What should you do?

A

Admit the patient for treatment, seeking legal advice if she continues to refuse treatment

This individual is under the age of 16 and is deemed to have capacity.

Therefore, they have the right to agree to a treatment without a parent’s consent, but if they choose to refuse it, you must weigh up their best interests.

As the patient has diabetic ketoacidosis, the decision to leave would most likely be fatal and so it would be fair to make the decision that it is in her best interests.
