The pig shows a marked response to end-to-side portacaval shunt. Survival is short and levels of alkaline phosphatase and cholesterol fall. This study was designed to determine the role of the reduced food intake which follows the operation upon these results. In pair-fed, sham-operated pigs, survival was short and levels of alkaline phosphatase and cholesterol also fell. Sham-operated animals fed normally did not show this response. Reduced appetite has been recorded in many experimental animals after portacaval shunt, but the cause remains to be elucidated. Encephalopathy, bacteremia, peptic ulceration, or hormonal imbalance could be implicated. Similar alteration in appetite and weight loss have not been observed in children who have been treated by portacaval shunt for glycogen storage disease or hypercholesterolemia; however, the underlying metabolic disorder or the species difference may be a contributory cause.

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.

Cholesterol, triglyceride, free fatty acid, and phospholipid concentrations were measured in 33 brain, liver, and adipose tissue samples obtained from 17 children who died of an acute encephalopathy associated with liver dysfunction and hyperammonemia (hyperammonemic encephalopathy). Eleven patients had Reye's syndrome, three had acute "toxic" encephalopathy (without fatty liver), two had glycogen storage disease type 1, and one had congenital hyperammonemia type 2. Hepatic triglyceride concentrations were markedly increased in Reye's syndrome, but varied from normal to increased concentrations in other hyperammonemic encephalopathies. In contrast, the acute encephalopathy could not be differentiated on the basis of clinical, laboratory, or pathologic features and the brain lipid profiles were remarkably similar among all patients studied.

A total of 11 types of glycogen storage disorders have been recognized with variable clinical presentations. Type IV, also known as Andersen disease, represents a rare subtype that can induce severe clinical findings early in life. We report on a patient with early fetal onset of symptoms with severe neuromuscular findings at birth. The pregnancy was further complicated by polyhydramnios and depressed fetal movement. At birth severe hypotonia was noticed requiring active resuscitation and then mechanical ventilation. His lack of expected course for hypoxic ischemic encephalopathy prompted genetic testing, including a muscle biopsy, which confirmed the diagnosis of glycogen storage disease IV (GSD IV). Mutation analysis of the glycogen branching enzyme 1 gene demonstrated a previously unrecognized mutation. We review recent information on early presentation of GSD IV with particular interest in the presentation of the neonatal lethal neuromuscular form of this rare disorder.

Liver cirrhosis represents a state of end-stage failure that is usually fatal. The condition results in liver dysfunction, recurrent ascites, encephalopathy, renal failure, splenomegaly, bleeding, and a poor quality of life in general. With the current severe shortage of donated organs, the only available treatment in the developing countries remains palliative care. We report a case of congenital metabolic liver cirrhosis due to glycogen storage disease diagnosed at age eight. The patient, a male, received bone marrow derived mononuclear cells (BMMC) at age 16 and again at age 17 with significant improvement of his biochemical liver function tests, ascites build-up, asthenia, splenomegaly and quality of life. Furthermore, liver biopsies showed clear reduction of the inflammation and fibrosis from Ishak score dropped from 3 to 1 paralleling the symptomatic improvement of the patient.

Glycogen storage disease (GSD) type 1b (Online Mendelian Inheritance in Man [OMIM] 232220) is an autosomal recessive inborn error of carbohydrate metabolism caused by defects in glucose-6-phosphate translocase. GSD1b patients have severe hypoglycemia with several clinical manifestations of hepatomegaly, obesity, a doll-like face, and neutropenia. Liver transplantation (LT) has been indicated for severe glucose intolerance, poor metabolic control (PMC), and poor growth (PG). We retrospectively reviewed 11 children with GSD1b who underwent living donor liver transplantation (LDLT) at the National Center for Child Health and Development in Tokyo, Japan. Between November 2005 and December 2018, 495 children underwent LDLT with an overall 10-year patient and graft survival of 90.6% and 88.9%, respectively. Of these, LT was indicated for 11 patients with GSD1b. All patients are doing well with the stabilization of glucose intolerance and decreased hospitalization for infectious complications. Demand for granulocyte colony-stimulating factor significantly decreased. However, although LT stabilized the blood glucose level, the platelet function was not improved. The posttransplant developmental quotient (DQ) remained similar to the pretransplant DQ without deterioration. LDLT is a feasible procedure for GSD1b patients with regard to the longterm prognosis. LT should be considered for patients with severe glucose intolerance to protect the cognitive function against hypoglycemic encephalopathy and to ameliorate PMC and PG.
