    Curling Ulcer

    A type of ulcer that occurs after extensive burn injuries, often affecting the stomach antrum or duodenum.

    Cushing Ulcer

    A type of ulcer linked to head injuries, strokes, brain tumors, or intracranial surgery. It arises due to increased intracranial pressure, leading to overstimulation of the vagus nerve and excessive gastric acid secretion.

    Gastric Mucosa Damage

    A condition where the protective lining of the stomach (gastric mucosa) is damaged, potentially leading to ulcers.

    Study Notes

    Digestive System Overview

    • Digestion, absorption, and elimination are the major functions
    • Enzymes like ptyalin (salivary amylase), pepsin, hydrochloric acid, and others aid digestion
    • Organs involved include the mouth, stomach, pancreas, liver, and intestines

    Peptic Ulcer Disease

    • Peptic ulcers are erosions in the mucosal lining of the stomach, duodenum, or esophagus
    • Duodenal ulcers are more common than stomach ulcers
    • NSAIDs (Nonsteroidal Anti-inflammatory Drugs) are a major risk factor
    • Helicobacter pylori (H. pylori) infection also impairs the protective lining and increases ulcer risk.

    Pathophysiology

    • Increased acid secretion, or decreased mucosal resistance, are contributing factors.
    • H. pylori infection is the most frequent cause of peptic ulcers, followed by NSAID use.
    • Zollinger-Ellison syndrome is a relatively rare cause.

    Predisposing Factors

    • First-degree relatives with PUD
    • African American/Hispanic ethnicity
    • Blood type O

    Types

    • Curling ulcers: often after extensive burn injuries, affecting the stomach or duodenum
    • Cushing ulcers: common in patients with traumatic brain injuries, strokes, and certain surgeries, due to intracranial pressure and resulting in excessive vagal nerve stimulation.

    Diagnostic Tests

    • Physical examination
    • Endoscopy is used to visualize the stomach and upper intestines
    • Complete blood count (CBC) is assessed for inflammation
    • Stool exam for presence of blood
    • other relevant tests

    Management

    • Medications to decrease gastric acid (antacids, H2 blockers, proton pump inhibitors, etc.)
    • Medications to coat the ulcer lining (e.g. sucralfate)
    • Antibiotics to eradicate H. pylori (in cases where it is present)
    • Surgical interventions (vagotomies, pyloroplasty) depending on the severity or complications

    Pancreatitis

    • Inflammation of the pancreas.
    • Autodigestion of the pancreas is a key mechanism
    • Caused by duct obstructions, acinar cell injury or defective cellular transport.
    • Some contributing factors include gallstones (cholelithiasis), alcohol abuse, certain medications, and infections
    • Symptoms often include severe pain and tenderness in the upper abdomen

    Cholelithiasis

    • Presence of gallstones in the gallbladder.
    • Two main types: pigment stones and cholesterol stones.
    • Predisposing factors include age, sex, ethnicity, and presence of other diseases.
    • Pathophysiology focuses on the lack of bile salt dissolving the cholesterol in the bile, and excessive bile cholesterol production.

    Choledocholithiasis

    • Presence of gallstones in the common bile duct.
    • Similar pathophysiological mechanisms to those of cholelithiasis
    • This can cause blockage of bile flow into the duodenum

    Cholecystitis

    • Inflammation of the gallbladder.
    • Often related to gallstones (calculous cholecystitis) or lacking gallstones (accalculous cholecystitis)
    • Risk factors depend upon factors like age, diet, and diseases.
    • Pathophysiology involves bile precipitation, chemical reactions within the affected organ (autolysis), and increased pressure within the GB

    Appendicitis

    • Inflammation of the appendix due to infection or irritation
    • It is one of the most common causes of acute abdominal pain.
    • Risk factors are related to those of the related disease (e.g. infections) as well as age and environment
    • Pain in the right lower quadrant is a frequently seen symptom.

    Diverticular Disease

    • Presence of diverticula in the colon (outpouchings).
    • Differentiate diverticulosis (prevalence of many diverticula; often asymptomatic) and diverticulitis (inflammation of diverticula, more severe and painful form)
    • Pathophysiology is based upon the low volume in the colon. Increased pressure and low fiber can contribute to the formation of diverticula
    • Pain, changes in bowel habits, fever and nausea are common signs.

    Gastritis

    • Inflammation of the stomach lining.
    • Can be acute (temporary inflammation) or chronic (persistent inflammation).
    • Factors contributing to gastritis include but not limited to infections (H. Pylori,) use of NSAIDs, alcohol exposure, autoimmune disorders, and heavy stress.
    • Symptoms range from mild discomfort to severe pain and discomfort.
