Pathologically different features and fibrosis scores in chronic hepatitis C genotypes 3 and 1.

Background: Chronic hepatitis C genotypes 3 and 1 are the two most common genotypes in Thailand.

Objective: Identify the pathologically different features between genotypes 3 and land to compare the fibrosis score of Knodell HAI and Ishak modified HAI.

Material And Method: The pathological features of 114 liver biopsies were evaluated.

Vanishing bile duct syndrome in a child with toxic epidermal necrolysis: an interplay of unbalanced immune regulatory mechanisms.

Vanishing bile duct syndrome (VBDS) is a rare disorder and requires a liver biopsy for a diagnosis. The condition has not been reported in children with toxic epidermal necrolysis (TEN). The etiology of VBDS in our patient with TEN is most likely from drug hypersensitivity.

A rapid serologic test and immunoblotting for the detection of Helicobacter pylori infection in children.

The gold standard for the diagnosis of Helicobacter pylori infection requires an endoscopic biopsy of gastric mucosa for histological examination, urease test and culture. Noninvasive serological tests are useful as a screening test for H. pylori infection.

Hematemesis in infants induced by cow milk allergy.

This study was conducted in order to analyze the clinical manifestations, the endoscopic findings, the histology of the gastrointestinal mucosa, the treatments and the clinical course in infants who had hematemesis induced by cow milk allergy. The medical records were reviewed retrospectively. The criteria for the diagnosis of CMA included elimination of cow milk formula resulting in improvement of symptoms, specific endoscopic and histologic findings as well as the exclusion of other causes.

Histology of gastritis and Helicobacter pylori infection in Thailand: a nationwide study of 3776 cases.

Background: Dyspepsia is a very common problem in Thailand. Etiology of gastritis, incidence of Helicobacter pylori and mode of transmission of Helicobacter pylori infection in the country was proposed.

Methods: A nation-wide study of gastric biopsy in 3776 dyspeptic patients from six different geographic regions for incidence of gastritis, type of gastritis, incidence of H.
