amiodarone
RAI
Pheochromocytoma etiology and tx
- benign tumor on adrenals
- HTN, hypokalemia
- surgical removal
Addison’s disease findings and diagnostic testing
- hyperpigmentation, hyponatremia, hyperkalemia
- Cosyntropin stimulation test (synthetic ACTH)
Hypoglycemia clinical manifestations
Autonomic: tremors, sweating, palpations, hunger, paresthesias
Neuroglycopenic: confusion, fatigue, seizure, coma
Myasthenia gravis antibody

- Cushing dz: pituitary adenoma
- adrenal hyperplasia, adenoma, carcinoma
- ACTH secretion secondary to small cell lung ca
Addison’s dz causes, lab findings, presentation
- Primary adrenal insufficiency: autoimmune or infectious (HIV, TB, fungal)
- LOW plasma cortisol
- HIGH ACTH
- HYPOnatremia, HYPERkalemia
- weight loss, anorexia, hyperpigmentation, weakness, orthostatic hypotension
Addison’s dz diagnosis
cosyntropin test
Secondary adrenal insufficiency causes, lab findings, presentation
- pituitary tumor, post surgical, or post radiation
- LOW ACTH and no hyperkalemia
- Symptoms the same as primary except NO hyperpigmentation
