Abstract:
Helicobacter pylori is a microorganism that is highly prevalent in mankind and closely linked to several gastroduodenal disorders. Though Helicobacter pylori was introduced to the scientific community in 1983 by Robin Warren and Barry Marshall, a closely related Helicobacter species had been described one hundred years earlier by the Italian pathologist Giulio Bizzozero in the canine stomach. In this review we analyze the different steps involved in the discovery of Helicobacter and provide a biography of the pioneer Giulio Bizzozero.

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.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
