Q

Jaundice in neonate: physiological vs biliary atresia?

A

Physiological should NOT be seen beyond 2 weeks

Otherwise, consider biliary atresia: intra and extra-hepatic fibrosis which progresses to cirrhosis within 3-6 mths if untreated

24
Q

Haemochromatosis more common in males or females?

A

6X more common in males

25
Q

Haemochromatosis and adrenals?
