Abstract:
Mallory-Weiss tears are mucosal lacerations caused by forceful retching and are typically located at the gastroesophageal junction. Mallory-Weiss tears have not been described in the duodenum. We report of a Mallory-Weiss tear in the descending duodenum of a 57-year-old man who presented with hematemesis preceded by forceful retching. We discuss the pathophysiology of a duodenal injury in comparison to typical tears occurring at the gastroesophageal junction.

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.
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
