Abstract:
Henoch-Schonlein purpura (HSP) is an immune-mediated vasculitis. HSP presents with purple spots on the skin (purpura), arthralgia, digestive problems, and kidney injury. HSP is most commonly seen in children, and rarely presents in adults. The pathogenesis involves the deposition of immune complexes in small to medium size blood vessels which leads to necrosis and inflammation. Most patients recover after symptomatic treatment, while more severe cases are treated with steroids. We report a 28-year-old female patient who presented with two episodes of hematemesis, worsening abdominal pain, and bloody diarrhea. Physical examination showed erythematous, palpable, purpuric rashes on her thighs and lower legs. Contrast-enhanced computed tomography (CT) scan showed thickening of the duodenal wall, and upper endoscopy revealed mild gastric erythema and diffuse erythematous, hemorrhagic, friable mucosa with superficial, thick, adherent white exudate seen in the second portion of the duodenum, consistent with the diagnosis of HSP. We report on the clinical presentation of our patient, and review adult-onset HSP.

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.

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.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
