Q

Management of constipation in kids?

A

Check for faecal impactation: severe constipation, overflow soiling (very loose or rabbit droppings, or very large stools that can block toilet), faecal mass palpable in abdo

Maintenance is same - Movicol 1st line, lactulose added if no response

Ensure dietary fibre and enough fluids but don’t use this as 1st line alone

Q
Cow's milk protein intolerance/allergy presentation?
Investigation?
Management if formula fed?
Management if breast fed?
Prognosis?
A

Appears around 3 months in formula fed infants (can be in breast-fed rarely if mum drinks milk)

  • regurg and vomiting
  • diarrhoea
  • urticaria/atopic eczema
  • ‘colic’ - irritability/crying
  • wheeze/chronic cough
  • rarely angioedema/anaphylaxis

Usually clinical, but if needed:

  • ski prick/patch
  • total IgE and specific IgE (RAST) for cow’s milk protein
  • -> both type I/type IV can occur

Formula fed:

  • Extensive hydrolysed formula if formula-fed
  • amino acid-based formula if severe/still reacting to eHF

Breast fed:

  • continue breastfeeding
  • eliminated cow’s milk from maternal diet and consider calcium supplements
  • eHF when stop breastfeeding until 12 months

Prognosis:

  • IgE - 55% tolerant by 5y/o
  • Type IV - almost all tolerant by 3y/o

Q

Management of febrile convulsions?

Chance of epilepsy?

A

Any kid with first seizure admit to paeds

Risk of further = 1/3
If recurrences, teach parents to use rescue meds - buccal midazolam or rectal diazepam. Phone ambulance if >5 mins

Regular antipyretics = no benefit

2.5% chance of epilepsy in general public
Febrile convulsions alone raise this slightly

febrile convulsions + complex seizure + neurodevelopment disorder = 50% chance

Complex = 15-30 mins, focal, or repeat within 24 hours

Q

Classification of types of precocious puberty?

A

Gonadotrophin dependent (true)

Exomphalis - abdo contents protrude through wall but covered in amniotic sac formed by amniotic membrane and peritoneum

  • C-section at 37 weeks

A

Cephal - SVD/ventouse/forceps - tense swelling limited to frontanelle - weeks-months

Intracranial - epidural never happens. Subdural may occur rarely with forceps. SAH more common than that and can cause irritability/convulsions in first 2 days. Intraventricular commonest and occur if premature, also cause irritability and convulsions and hypotonia. USS scan
