Prospective cohort study of children exposed to hepatitis C virus through a pregnancy screening program.

Objectives: Porto Alegre, in south Brazil, has one of the highest hepatitis C virus (HCV) infection rates in the country (84.4 cases/100 000 in 2018). Prenatal screening of HCV, however, has not been routinely offered.

Prevalence of celiac disease in a large cohort of young patients with type 1 diabetes.

Background: Serological screening for celiac disease (CD) allows the identification of individuals genetically predisposed, as type 1 diabetes mellitus (T1DM). However, the diagnosis is confirmed by intestinal biopsy. The aim was to determine the prevalence of immunoglobulin-A anti-tissue transglutaminase antibodies (IgA-tTG) and CD in a large cohort of young T1DM patients.

Hirschsprung disease and hepatoblastoma: case report of a rare association.

Context: Hirschsprung disease is a developmental disorder of the enteric nervous system that is characterized by absence of ganglion cells in the distal intestine, and it occurs in approximately 1 in every 500,000 live births. Hepatoblastoma is a malignant liver neoplasm that usually occurs in children aged 6 months to 3 years, with a prevalence of 0.54 cases per 100,000.

Intestinal permeability assessed by 51Cr-EDTA in rats with CCl4 - induced cirrhosis.

Context: The straight relationship between cirrhosis and impaired intestinal barrier has not been elucidated yet.

Objectives: To verify (51)Cr-EDTA-intestinal permeability in rats with CCl(4)-induced cirrhosis and controls.

Method: Fifty male Wistar rats weighing 150-180 g were separated in three groups: 25 animals received CCl(4) 0.

The role of food restriction on CCl4-induced cirrhosis model in rats.

Effects of food restriction on susceptibility to the toxic effect of some chemicals are controversial. In order to identify an exposure model that could maximize cirrhosis and minimize mortality rate, this study aimed to evaluate the effect of food restriction on tetrachloride carbon (CCl(4))-induced cirrhosis model in rats. Fifty-three male Wistar rats received CCl(4) 0.
