Background:
Gastritis has a broad histopathologic and topographical spectrum and leads to different patterns of disease. The introduction of the Sydney system made it possible to grade histological parameters, identify topographic distribution and provide etiological information which would help to generate reproducible and clincally useful diagnoses. The aim of this study was to determine the prevalence of Helicobacter pylori in non-ulcer dyspepsia, duodenal ulcer and gastric ulcer; and to assess the histopathologic features associated with chronic gastritis.
Methods:
Gastric antral biopsy specimens from 200 patients were examined for the prevalence of H. pylori, and were classified and graded histologically.
Results:
The overall colonization rate of H. pylori was 44%. The colonization rates were 85%, 67% and 41% in patients with duodenal ulcer, gastric ulcer and non-ulcer dyspepsia respectively. There was not much difference between the degree of atrophy and intestinal metaplasia in H. pylori positive and negative cases.
Conclusions:
Helicobacter gastritis is the commonest type of gastritis present in patients presenting with dyspeptic symptoms. It is more common in patients presenting with duodenal ulcer. Adequate sampling is a must for accurate diagnosis of H. pylori colonization.

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
01:27Gastritis-I: Introduction and Types
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...
