This covers definition pathophysiology causes symptoms diagnosis differentials full management drugs with MOA, doses, adverse effects rehabilitation prevention . --- STROKE COMPLETE DETAILED NOTE --- 1. DEFINITION A stroke (cerebrovascular accident) is an acute neurological deficit caused by interruption of blood flow to the brain either due to vessel occlusion (ischemic stroke) or rupture (hemorrhagic stroke) leading to rapid loss of brain function. --- 2. CLASSIFICATION A. Ischemic Stroke ( 85 ) Caused by reduced or blocked blood flow. Types 1. Thrombotic plaque rupture clot formation in cerebral artery 2. Embolic clot from heart or large vessels brain 3. Lacunar small perforator artery occlusion (HTN related) 4. Watershed infarcts systemic hypotension B. Hemorrhagic Stroke ( 15 ) 1. Intracerebral hemorrhage (ICH) rupture of small arteries (HTN common) 2. Subarachnoid hemorrhage (SAH) rupture of saccular aneurysm --- 3. PATHOPHYSIOLOGY Brain needs continuous oxygen and glucose . Interruption of blood flow energy failure Na /K pump failure cellular swelling cytotoxic edema . Excitotoxicity via glutamate release neuronal death. Ischemic core (irreversible) penumbra (salvageable with timely reperfusion). Hemorrhagic stroke bleeding mass effect, ICP reduced perfusion neuronal injury. --- 4. RISK FACTORS / CAUSES Non-modifiable Age Male sex Family history Prior stroke/TIA Genetic disorders (CADASIL) Modifiable Hypertension (strongest risk factor) Diabetes mellitus Dyslipidemia Atrial fibrillation Smoking, alcohol Obesity Carotid stenosis Sedentary lifestyle Oral contraceptives Hypercoagulable states Causes of Embolic Stroke Atrial fibrillation MI with mural thrombus Prosthetic valves Endocarditis PFO/ASD with paradoxical emboli --- 5. CLINICAL FEATURES Symptoms depend on the arterial territory. General Symptoms Sudden onset focal neurological https://vidshare.erroron.space/uploads/videos/file_6921b47aa36f8.mp4 120 2025-11-22T13:02:50+00:00 yes https://vidshare.erroron.space/video/signs-and-symptoms-of-primary-hyperparathyroidism 2025-11-22T13:08:16+00:00 daily 0.6 https://vidshare.erroron.space/uploads/videos/thumb_6921b5c085c21.jpg Signs and Symptoms of Primary Hyperparathyroidism Below is your complete, expanded, exam-ready clinically robust reference on Primary Hyperparathyroidism (PHPT) following your template Definition Pathophysiology Causes Clinical Features Investigations Differential Diagnosis Management (stepwise) Drug details Monitoring Counselling Concise but exhaustive , suitable for NEET PG physicians your ErrorOn Space content. --- PRIMARY HYPERPARATHYROIDISM (PHPT) COMPLETE DETAILED NOTE --- 1) Definition Primary hyperparathyroidism is a disorder characterized by autonomous overproduction of parathyroid hormone (PTH) from one or more parathyroid glands, leading to hypercalcemia and hypophosphatemia with widespread metabolic, renal, skeletal, and neuropsychiatric effects. --- 2) Pathophysiology Excess PTH causes A. Bone Osteoclast activity Bone resorption Cortical bone loss (radius most affected) Osteitis fibrosa cystica (late) B. Kidneys Calcium reabsorption Phosphate reabsorption hypophosphatemia 1 -hydroxylase 1,25-(OH) -Vitamin D gut calcium absorption Nephrolithiasis and nephrocalcinosis C. GI Gastrin peptic ulcer Calcium absorption D. Cardiovascular Short QT interval Hypertension Arrhythmias (rare) --- 3) Etiology (Causes) A. Parathyroid Adenoma (80 85 ) Single adenoma most common. B. Parathyroid Hyperplasia (10 15 ) All four glands enlarged. C. Parathyroid Carcinoma (14 mg/dL Immediate steps 1. IV normal saline 2. IV furosemide (after hydration) 3. IV calcitonin 4. IV bisphosphonate (zoledronic acid) 5. Dialysis if renal failure --- 8) Complications CKD Severe osteoporosis Pathological fractures Pancreatitis Peptic ulcer Parathyroid carcinoma (rare) Cardiac arrhythmias Hypercalcemic crisis --- 9) Monitoring After Treatment If Surgery Done Serum calcium at 24 hours PTH within 6 months DEXA every 12 24 months If Managed Medically Serum calcium every 6 months PTH every 6 12 months Vitamin D yearly DEXA every 1 2 years Renal ultrasound yearly --- 10) Patient Counselling Points Stay well hydrated Avoid thiazide diuretics Avoid prolonged immobilization Maintain Vit D in norm https://vidshare.erroron.space/uploads/videos/file_6921b5c083ebd.mp4 120 2025-11-22T13:08:16+00:00 yes https://vidshare.erroron.space/video/cushing-syndrome 2025-11-22T18:18:16+00:00 daily 0.6 https://vidshare.erroron.space/uploads/videos/thumb_6921fe6813bce.png Cushing syndrome I can generate all 55 Cushing Syndrome case-scenarios with detailed diagnosis steps complete management drug-wise Rx , but 55 full scenarios will be extremely long for a single message and may exceed limits. Before I generate, tell me which format you prefer --- Choose Format Option A Ultra-Detailed Format Each case includes Presenting complaint Vitals, labs, CT/MRI findings Step-by-step diagnosis Full management All drugs with MOA, dose, PK, ADRs, contraindications, monitoring Follow-up counseling (This becomes very long 55 cases 150 200 pages equivalent.) --- Option B Exam-Ready Clinical Format Each case includes Short case Key findings Diagnosis Management (brief but complete) Rx with only essential drug details Good for NEET PG / FMGE / ErrorOn Space content --- Option C Mixed Format (Recommended) 55 cases Medium-length Includes diagnosis management precise drug regimen All essential details (but not expanded PK of every drug) Best balance of readability exam prep website use Great I will give 35 Cushing Syndrome case scenarios , each with Complete case presentation Interpretation , diagnosis steps Management Full drug Rx (MOA, Doses, ADR, monitoring, contraindications) but concise Follow-up counseling All content will be NEET PG / clinical-practical ready and suitable for ErrorOn Space uploads. --- 35 CASE SCENARIOS OF CUSHING SYNDROME (WITH MANAGEMENT RX) Carefully optimized for medicine endocrinology exam clinical use --- CASE 1 Classic Cushing Disease (Pituitary Adenoma) A 32-yr female presents with weight gain, amenorrhea, purple striae, proximal muscle weakness, BP 158/100, fasting glucose 168 mg/dL.
