Study Notes
Definition
- Peptic ulcer: A break in the gastrointestinal mucosa exceeding 3 mm in diameter.
- Commonly occurs in the first portion of the duodenum in Western populations; gastric ulcers are more prevalent in Asia.
- Peptic ulcer disease typically chronic and focal; around 10% of patients have multiple ulcers.
Gastric Protective Barrier
- The protective factors of gastric mucosa include:
- Thick mucous layer
- Integrity of epithelial cells
- Adequate mucosal blood flow
Causes of Peptic Ulcer Disease (PUD)
- Primary cause is Helicobacter pylori (H. pylori), found in:
- 80% of normal populations
- 60-90% of duodenal ulcers
- 50-70% of gastric ulcers
- H. pylori damages mucosal lining via ammonia production and immune response.
- NSAIDs are the second most common cause of peptic ulcers.
- Other contributing factors include:
- Acid hypersecretion
- Alcohol consumption
- Cigarette smoking
- Psychological and physical stress
Clinical Picture
-
Symptoms may be asymptomatic or include:
- Epigastric pain: Long-standing, localized, often burning or gnawing in nature.
- Duodenal ulcers cause pain after meals, waking patients at night; relief often comes from food, milk, or antacids.
- Gastric ulcer pain is unpredictable; eating may worsen pain.
-
Dyspepsia: Nausea and vomiting linked to meal timing.
- Gastric ulcers induce nausea immediately post-meal; duodenal ulcers typically 30-60 min after eating.
-
Hematemesis and melena: Symptoms indicating upper gastrointestinal bleeding.
Complications
- Potential complications of peptic ulcers include:
- Perforation of the ulcer
- Nutritional status impact
- Upper gastrointestinal bleeding
- Association with Mucosal Associated Lymphoid Tissue (MALT) lymphoma.
Oral Manifestations
- Systemic antibiotics for ulcers can cause oral fungal overgrowth (e.g., candidiasis).
- Dentists should look for oral fungal infections like median rhomboid glossitis and report vascular malformations in patients (commonly in older men).
- Enamel erosion may occur due to regurgitation of gastric juices, particularly with pyloric stenosis, necessitating medical evaluation.
Medication Effects
- Treatments can lead to oral side effects:
- Proton Pump Inhibitors (PPIs): Alter taste perception.
- Famotidine and anticholinergics (e.g., propantheline): Associated with xerostomia (dry mouth).
- Xerostomia increases risk for bacterial infections (caries, periodontal disease) and fungal infections (candidiasis).
- Drug-induced erythema multiforme linked to the use of cimetidine, ranitidine, omeprazole, and lansoprazole.
- H. pylori presence in dental plaque may facilitate infection and reinfection; maintaining good oral hygiene can help mitigate this risk.
