Paediatric liver disorders in Singapore.

Abstract

The liver in an infant or child is as liable to the same pathologies afflicting the adult liver but with certain differences in prevalence and causes. Genetic disorders are more likely to present in the paediatric age group where many involve metabolic processes such as galactosemia, phenylketonuria, glycogen storage disease and others. Many of these present in the newborn period. However, neoplasms and hamartomas also present in the newborn period, such as congenital neuroblastoma with an enormously enlarged liver, hepatoblastoma and haemangioma. The latter may present with intractable cardiac failure as a result of considerable shunting of blood. Acquired liver lesions often present in the newborn period or early infancy and this includes hepatitis and biliary atresia. The difficulties in the differentiation of the two lesions will be discussed together with the management of biliary atresia. As the child grows older, Reyes encephalopathy with microvesicular fat in the liver is not uncommon. The pathophysiology of Reyes encephalopathy as seen locally will be described. The choledochal cyst with direct (Caroli's disease) or indirect effect on the liver will be described. Problems of childhood portal hypertension as well as congenital hepatic fibrosis will be described. Hemosiderosis of the liver is chiefly seen in homozygous beta-thalassaemia patients who have been kept alive with repeated blood transfusions. Amoebic and pyogenic hepatitis, fatty liver due to protein malnutrition, biliary ascariasis, etc, which are common in tropical and subtropical countries are rarely seen now in Singapore children.
