Abstract:
Marshall and Warren were the first to succeed in culturing Helicobacter pylori (H. pylori) from the gastric mucosa of patients with gastritis in 1983. H. pylori is a spiral-shaped bacterium that resides in the gastric mucosa and is one of the most common infections worldwide. H. pylori infection causes gastritis and peptic ulcers and is associated with the development of gastric cancer and MALT lymphoma. Now, a variety of accurate diagnostic tests are widely available. Both invasive tests (bacterial culture, histopathology, and RUT) and non-invasive tests (UBT and serological test) are conducted for the diagnosis of H. pylori infection. This review provides a general overview of the diagnostic methods and tests the characteristics (sensitivity and specificity) for H. pylori infection.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
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.

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...
