BACKGROUND Nodularity on the gastric mucosa is occasionally seen in general practice. There is no consensus about the association of nodular gastritis and histological premalignant lesions. This study is designed to investigate the prevalence of histological premalignant lesions in dyspeptic patients with endoscopic nodular gastritis. METHODS Consecutive patients with endoscopic nodular gastr...

BACKGROUND The incidence and mortality from gastric cancer is high in Japanese but extremely low in Thailand. It is different among Asian countries. The aim of this study is to investigate the difference of peptic ulcer disease, glandular atrophy, intestinal metaplasia and topography of chronic active gastritis between the Nepalese and Japanese population.

The Helicobacter pylori is associated with the development of different diseases. The clinical outcome of infection may be associated with the cagA bacterial genotype. The aim of this study was to determine the EPIYA patterns of strains isolated from patients with gastritis and gastric adenocarcinoma and correlate these patterns with the histopathological features. Gastric biopsy samples were s...

A population-based screening for detection of early cancers evaluated the prevalence of precancerous gastric lesions in an area in Shandong province, China, with one of the world's highest rates of stomach cancer. A total of 3433 residents aged 35 to 64 yr received gastroscopical examinations with biopsies taken from standard locations. Chronic atrophic gastritis was nearly universal; less than...

Barrett's metaplasia consists of columnar epithelium that replaces the normal esophageal mucosa in patients with chronic gastroesophageal reflux. Because intestinal-type Barrett's metaplasia is the major risk factor for adenocarcinoma development, understanding the mechanisms that predispose the esophageal mucosa to malignant degeneration is clinically important. Glutathione s-transferase (GST)...

background many studies have reported an association between periodontal infections and some systemic diseases such as respiratory and cardiovascular diseases. some studies found a direct association between chronic gastritis caused by helicobacter pylori (hp) infection and poor periodontal health. methods in a cross-sectional study from november 2014 to december 2015 in kerman, the largest pro...

BACKGROUND Helicobacter pylori (H. pylori) colonizes in half of the population of developed and nearly all inhabitants of developing countries. The infection is characterized by gastritis but can present more complicated disease states. We intended to report prevalence of H. pylori infection by histopathology and presence of gastritis, activity, atrophy and intestinal metaplasia in dyspeptic pa...

INTRODUCTION Chronic atrophic gastritis, intestinal metaplasia, hereditary non-polyposos colon cancer, gastric dysplasia, gastric adenoma, Barrett esophagitis and familiar adenomatous polyposis are confirmed precancerous lesions of the stomach. Most of these conditions are correlated with long-term infections with Helicobacter pylori. MATERIAL AND METHOD Patients which were included in our st...
