Study Notes
Oral Cancers
- Oral cancers are prevalent, particularly among tobacco users.
- Tobacco irritation leads to leukoplakia, characterized by white patches on the mucosa, especially on lips and tongue.
- Leukoplakia lesions can become malignant and have well-defined borders.
- Treatment options include surgery and chemical agents like radiation or chemotherapy.
- Lip cancer typically responds well to treatment, while tongue margin cancers often metastasize swiftly, complicating treatment.
Esophageal Disorders
Hiatal Hernia
- Hiatal hernia involves stomach protrusion through a weakened cardiac sphincter into the diaphragm.
- Common in individuals over 40 years; weight gain is a significant risk factor.
- Normally, the cardiac sphincter prevents gastroesophageal reflux, which is compromised by hiatal hernia.
- Symptoms include abdominal pain and indigestion, particularly after meals.
- Diagnosis involves medical history, chest imaging, barium swallow, or endoscopy.
- Medical treatment is favored over surgery due to high recurrence rates.
- Treatment strategies include dietary changes, antacids, weight loss, and elevating the head during sleep.
- Persistent gastroesophageal reflux can lead to esophagitis and potentially Barrett esophagus, increasing esophageal cancer risk by 30% to 40%.
Stomatitis
- Stomatitis refers to inflammation of the oral mucosa caused by viruses, bacteria, or fungi.
- Common forms include herpetic stomatitis (herpes simplex virus) and candidiasis (Candida albicans).
- Herpes simplex is typically self-limiting, with painful mucosal sores as a symptom.
- The virus can reactivate due to stress or sun exposure after initial infection.
- No cure exists for herpes simplex, but palliative treatments are available for symptom relief.
- C. albicans is an opportunistic fungus present in the mouth, typically controlled by oral bacteria.
- Disruptions in normal bacterial balance can lead to C. albicans overgrowth, causing white oral lesions.
