Study Notes
Multiple Sclerosis (MS)
- Demyelination of nerve fibers in the central nervous system (CNS) leads to the formation of plaques.
- The etiology of MS is unknown (idiopathic), but infections, such as Torque teno virus or Epstein Barr virus, and environmental factors may play a role.
- Early symptoms include vision changes (blurred vision, double vision, nystagmus), mobility issues (tremor, spasticity, muscle weakness), and fatigue.
- Diagnosis is confirmed using magnetic resonance imaging (MRI) which reveals lesions within the brain.
- Treatment strategies aim to prevent injuries, promote physical mobility, manage pain, and enhance bladder and bowel function.
Myasthenia Gravis (MG)
- MG is a rare autoimmune disorder that causes muscle weakness, particularly affecting the ocular and bulbar muscles.
- The underlying cause is unknown (idiopathic), but the condition can be induced by drugs, thymic disorders, Graves' Hyperthyroidism, and environmental factors.
- Characterized by "fatigable" muscle weakness that worsens with activity and improves with rest.
- Common symptoms include droopy eyelids (ptosis), double vision (diplopia), difficulty swallowing (dysphagia), and respiratory distress.
- Diagnosis involves imaging studies, the Edrophonium Chloride (Tensilon) test, and blood tests for antibodies.
- Management focuses on respiratory support, eye protection, communication assistance, aspiration prevention, and mobility improvement.
- Medications like pyridostigmine and neostigmine increase acetylcholine levels to improve muscle strength.
- Thymectomy, surgical removal of the thymus gland, may be considered to help manage symptoms.
HIV/AIDS
- HIV infection attacks CD4+ T-helper cells, resulting in immunodeficiency and progressive disease over time.
- Transmission occurs through sexual contact, needlestick injuries, blood transfusions, and perinatal transmission.
- Key symptoms include Kaposi's sarcoma, opportunistic infections, weight loss, and neurological changes.
- No cure exists for HIV/AIDS, but treatment aims to maintain immune function and prevent progression using antiretroviral therapy (cART or HAART).
- The goal is to control viral load while preventing opportunistic infections.
- Treatment encompasses symptom management, including pain relief, infection control, oxygen therapy, and nutritional support.
Systemic Lupus Erythematosus (SLE)
- A chronic, progressive autoimmune disease affecting connective tissues and organs, leading to inflammation and potential organ dysfunction.
- The cause is unknown (idiopathic) but genetic, environmental, and hormonal factors may play a role.
- Symptoms include a butterfly rash (photosensitivity), fatigue, joint pain, weight loss, hair loss, and kidney/lung complications.
- Diagnosis involves a skin biopsy, blood tests (CBC, ESR, ANA), and clinical assessment.
- Management strategies focus on symptom control, flare prevention, and preventing organ damage.
- Medications include hydroxychloroquine, corticosteroids (prednisone), immunosuppressants, and NSAIDs.
- Patient education emphasizes sunlight/UV light avoidance, lifestyle modifications, and coping strategies.
