| Clinical presentation | Pathophysiology | Histopathological/gross appearance | Treatment/ Lab Tests | Miscellaneous | 
|---|---|---|---|---|
| 
					  What is Graves Disease					 
					 weight loss, hot flashes, bilaterally enlarged thyroid, warm dry skin, heart palpitations, nervousness, prone to thyroid storm | 
					  What is toxic adenoma					 
					 Activating mutations in TSH receptor or its associated G protein i.e. Gs alpha subunit mutation | 
					  What is papillary carcinoma					 
					 psammoma bodies, ground glass "orphan annie eye" nucleus, fibrovascular stalk | 
					  What is iodine replacement via diet or supplement					 
					 Iodine Deficiency Treatment | 
					  What is HT:: High TSH, low T4/T3, increases TRH, stimulates prolactin --> amennorhea via feedback inhibition. Cushing's --> neg feedback disrupt GnRH					 
					 Compare and contrast reason for amenorrhea in hypothyroidism vs. Cushing's disease | 
| 
					  What is Iodine Deficiency					 
					 bilaterally enlarged thyroid, gradual decline in mental function, gradual onset of fatigue, cold intolerant, overweight, constipation, dyspnea | 
					  What is thyroid stimulating immunoglobulin, binds to TSH receptor and mimics TSH action					 
					 Graves disease | 
					  What is graves' disease					 
					 diffuse hypertrophy and hyperplasia, tall and crowded follicular cells, pale colloid with scalloped margins | 
					  What is radioactive iodine therapy, methimazole, propylthiouracil, beta blockers, thyroidectomy					 
					 Graves Disease Treatment | 
					  What is FAS binds FAS-L, --> DISC (death inducing signalling complex) - includes FADD, --> caspase 8, -->caspase 3 and BID. (extrinsic)					 
					 Death pathway experienced by thyroid cells in hashimoto thyroiditis | 
| 
					  What is functional thyroid adenoma					 
					 unilateral swelling of the thyroid - solitary nodule, hot on RAIU, weight loss, hot flashes, heart palpitations, nervousness | 
					  What is hashimoto thyroiditis					 
					 loss of self-tolerance to thyroid auto-antigens, increased T-cell activity and inflammatory response | 
					  What is hemorrhagic adrenals, presenting with hypotension and DIC secondary to N. meningitis					 
					 Waterhouse-Friderichsen | 
					  What is hashimoto thyroiditis					 
					 decreased T3/T4, increased TSH, elevated WBC and inflammatory markers | 
					  What is labs: hypocalcemia, increased calcitonin Mutation: RET activation					 
					 Familial Medullary Thyroid Carcinoma: lab levels? mutation? | 
| 
					  What is Hashimoto Thyroiditis					 
					 An older female, diffusely enlarged thyroid, cold on RAIU, decline in mental function, weight gain, fatigue, constipation | 
					  What is issue with: iodine transport into cell, moves basal to apical movement, oxidized by peroxidase, combined with thyroglobulin - forms MIT/DIT					 
					 Iodine Deficiency | 
					  What is Hashimoto Thyroiditis (Hurthle cells = metaplastic response to inflammation)					 
					 lymphocytic invasion, extensive mononuclear infiltrate, Hurthle cells | 
					  What is toxic adenoma					 
					 high T3/T4, low TSH | 
					  What is hyperaldosteronemia - Conn's syndrome - via adrenal hyperplasia (17-OH deficiency), adenoma					 
					 hypertension, hypernatremia, hypokalemia, alkalosis, low renin | 
| 
					  What is Cushing's Disease					 
					 weight gain, buffalo hump, abdominal striae, high blood pressure, hyperglycemia, fatigue, oligomenorrhea | 
					  What is MEN 1 --> parathyroid, pituitary, and pancreatic endocrine tumors					 
					 mutation in menin, increased calcitonin, hyperparathyroidism, Zollinger-Ellison syndrome | 
					  What is toxic adenoma					 
					 well-circumscribed mass with capsule demarcated from adjacent parenchyma, uniform follicles, homogeneous follicular cells | 
					  What is when in acute need - i.e. surgery - T4 takes 6 weeks to show improvement, T3 takes only 2.					 
					 When would you give T3 as opposed to T4 | 
					  What is pituitary adenoma					 
					 dexamethasone test - fail single, fail low, pass high |
