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.
