typically presents as swelling 12-72hours post-delivery and associated with ventouse deliveries.
32
What is craniosynostosis?
uncommon and is where there is premature closure of cranial sutures, causing deformity of the skull. It can be evident at birth and may be associated with genetic syndromes.
The shape of the skull will depend upon which sutures are involved.
Other clinical features include early closure of the anterior fontanelle and raised ridge along the fused suture.

- autosomal dominant
autosomal recessive - usually metabolic diseases (exceptions: structural causes such as ataxia telangiectasia and Freiderich's ataxia)
autosomal dominant - usually structural diseases (exceptions: Gilbert's, hyperlipidaemia type II)

Severe - Frequent barking cough
Prominent inspiratory (and occasionally, expiratory) stridor at rest
Marked sternal wall retractions
Significant distress and agitation, or lethargy or restlessness (a sign of hypoxaemia)
Tachycardia occurs with more severe obstructive symptoms and hypoxaemia
38

(leading to)
increase compliance
(leading to)
reduce work of breathing
41
Why do we give dexamethasone to premature labour mother?
Natural maternal glucocorticosteroids are very important for surfactant production in the foetus, and therefore synthetic steroids are the first line agents for preventing NRDS in pregnancies at risk of pre-term birth.

Anaphylaxis
48
Contraindication to live vaccine
Pregnancy
immunosuppression
49
Transient synovitis VS septic arthritis in child
(Hint: presenting complaint differences)
hip pain, limp and recent infective/autoimmune illness : transient synovitis

ESR >40mm/hr
The probabilities are calculated thus:
0 points = very low risk
1 point = 3% probability of septic arthritis
2 points = 40% probability of septic arthritis
3 points = 93% probability of septic arthritis
4 points = 99% probability of septic arthritis
