Study Notes
Addison's Disease
- Autoimmune disorder characterized by organ-specific circulating autoantibodies.
- Rare cases may be caused by tuberculosis or fungal infections, often linked to HIV.
- Adrenal insufficiency disrupts electrolyte and fluid balance, leading to severe clinical consequences.
- Compensatory overproduction of adrenocorticotropic hormone (ACTH) leads to skin and mucosal pigmentation.
- Initial pigmentation often appears on gingivae, buccal mucosa, and lips, resembling a suntan; can range from brown to nearly black.
- Long-term management typically involves oral hydrocortisone, with dosage adjustments needed during stress or illness.
- Insufficient steroid treatment may precipitate an Addisonian crisis, presenting severe health risks.
Clinical Features of Addison's Disease
- Symptoms include lassitude, anorexia, weakness, fatigue, and craving for salt due to low aldosterone levels.
- Gastrointestinal issues such as diarrhea, nausea, and vomiting may occur alongside significant weight loss and low blood pressure.
- Increased risk for hypotensive crises and potential association with chronic mucocutaneous candidiasis in different syndromes.
Diagnosis of Addison's Disease
- Diagnosed by monitoring low blood pressure and elevated ACTH levels.
Management of Addison's Disease
- After confirming diagnosis through histology, antifungal treatment for secondary infections may be necessary, though difficult to eradicate completely.
- Miconazole gel is effective, sometimes requiring systemic options like fluconazole.
Oral Tuberculosis
- Oral tuberculosis is uncommon and usually associated with active pulmonary disease.
- Typically affects elderly men with chronic undiagnosed pulmonary infections, showing symptoms like chest pain and weight loss.
- Characterized by painless ulcers on the mid dorsum of the tongue with distinct angular or stellate shapes.
Oral Crohn’s Disease
- Presents with soft or tense swelling of lips, cobblestone buccal mucosa, erythematous gingivae, and painful linear mucosal ulcers.
- Glossitis may arise from deficiencies in iron, folate, or vitamin B12 due to malabsorption.
Ulcerative Colitis
- Chronic inflammation of the large intestine leading to ulceration, with oral manifestation linked to pyostomatitis vegetans and related anemia.
Coeliac Disease
- Permanent intolerance to gliadin, resulting in inflammation of the small intestine and villous atrophy.
- Malabsorption can lead to deficiencies, particularly iron and folic acid; can present various oral lichen planus types.
Lichen Planus
- Cutaneous lichen planus appears as dusky pink papules with Wickham's striae; typically occurs in flexor regions and other sites.
- Histological features include hyperkeratosis, lymphocytic infiltrate, and significant basal cell destruction.
Lichenoid Reactions
- Induced by various triggers, including drugs, making clinical differentiation from lichen planus challenging.
- Commonly involved drug categories include NSAIDs, ACE inhibitors, and antimalarials, emphasizing the need for thorough patient drug histories.
Topical Lichenoid Reactions
- Can be triggered by restorative materials like amalgam, localized to the areas in contact with materials.
- Clinical features often mimic lichen planus or lupus erythematosus.
Management of Lichenoid Reactions
- Symptomatic treatments aim to manage flare-ups; many asymptomatic lesions require no intervention.
