Age-specific causes of upper gastrointestinal bleeding in children.

The etiology of upper gastrointestinal bleeding (UGIB) varies by age, from newborns to adolescents, with some of the causes overlapping between age groups. While particular causes such as vitamin K deficiency and cow's milk protein allergy are limited to specific age groups, occurring only in neonates and infants, others such as erosive esophagitis and gastritis may be identified at all ages. Furthermore, the incidence of UGIB is variable throughout the world and in different hospital settings.

Predictive value of hepatic ultrasound, liver biopsy, and duodenal tube test in the diagnosis of extrahepatic biliary atresia in Serbian infants.

Background/aims: Extrahepatic biliary atresia (EHBA) is the most important cause of neonatal cholestasis. The validity of different diagnostic methods in the diagnosis of EHBA in developed countries has been presented elsewhere, but data from developing countries with low national incomes are scarce. The aim of this study was to investigate the relative accuracy and roles of abdominal ultrasonography, duodenal tube test (DTT), and liver biopsy in the diagnosis of EHBA in Serbia.

Profile of typical and atypical celiac disease in Serbian children.

We compared the clinical, biopsy and serology profile in typical vs atypical celiac disease. Mean TTG value for Marsh 3b/c in typical group was (140.53+/-88.

[Sample representativeness and incidence of liver biopsy complications caused by needles of bigger diameter (1.6 mm) and smaller diameter (1.2 mm) in children with cholestatic syndrome].

Introduction: Percutaneous liver biopsy and histomorphological analysis of liver tissue is an important diagnostic procedure in the investigation of neonates and infants with cholestatic syndrome. This study has been aimed at determining whether there is a difference in the incidence of complications after liver biopsy performed by Menghini technique using a needle of 1.6 mm as compared to 1.

Primary Budd-Chiari syndrome in a 3-year-old boy with homozygous factor V Leiden G1691A mutation.

Unlabelled: Budd-Chiari syndrome (BCS) is an uncommon disorder characterized by obstruction of hepatic venous outflow. The primary BCS is a rare disease with an incidence about 0.2 per million inhabitants per year.

Twelve-year-old girl with primary biliary cirrhosis.

Primary biliary cirrhosis (PBC) is a slowly progressive cholestatic liver disease of autoimmune etiology. The initial presentation of PBC is varies from asymptomatic, abnormal liver biochemical tests to overt cirrhosis. Unlike other autoimmune liver diseases, PBC has rarely been reported in childhood.

Cardiomyopathy associated with celiac disease in childhood.

Celiac disease is predominantly a disease of the small intestine characterized by chronic malabsorption in genetically susceptible individuals who ingest grains containing gluten, such as wheat, barley, and rye. Although previously believed to be uncommon, celiac disease may be present in up to 1% of the adult and children population. Celiac disease is associated frequently with iron-deficiency anemia, dermatitis herpetiformis, selective IgA deficiency, thyroid disorders, diabetes mellitus, and various connective tissue disorders but is rarely associated with cardiomyopathy.
