Flashcards in Day 3 - Endo1 Quiz Deck (15):

Exophthalmos, most likely cause

Graves' disease


Diabetic gastroparesis dx & tx

Gastric emptying study; Metoclopramide (most common), Cisapride, Erthyromycin, Domperidone


Hyperthyroid disease radioactive iodine most likely to result in hypothyroidism: (1) Graves' disease (2) Toxic multinodular goiter (3) Toxic adenoma

Graves' disease (taken up by functional thyroid tissue in entire gland, not just hyperfunctional adenomatous tissue)


Tx of most common cause of hyperthyroidism

Graves' disease - radioactive iodine preferred over surgery (if pregnancy, surgery), other indications for surgery - coexisting thyroid nodule, very large goiter


Causes of hypoglycemia in non-diabetic pt

Insulinoma, exogenous insulin or sulfonylureas, alcohol-induced fasting, adrenal insufficiency


DKA p/w

Kussmaul breathing, weight loss, vomiting w/o diarrhea, polydipsia, polyuria


Non-thyroid lab findings may cause suspicion for thyroid disease

Hyperlipidemia, Unexplained hyponatremia, Elevated serum CPK


Hyperthyroidism pt w/ elevated anti-TPO antibodies at increased risk of which cancer

Thyroid lymphoma; Hashimoto's thyroiditis


Cause of hyperthyroidism in pt p/w (1) extremely tender thyroid (2) pretibial myxedema (3) pride? and recent weight loss in athletic professional? (4) palpation of single thyroid nodule (5) multiple thyroid nodules (6) recent imaging study using contrast & Jod-Basedow phenomenon, eye changes including edema, proptosis (7) History of thyroid surgery

(1) de Quervain's thyroiditis (2) Graves' disease (3) exogenous thyroid abuse (4) Toxic adenoma (5) Toxic multinodular goiter (6) Graves' disease (7) Excess thyroid hormone replacement


Next step: new nodule in pt w/ hyperthyroidism

TSH, Free T4; If hyperthyroidism, radionuclide scan


3 newer diabetic drugs

Exenatide, sitagliptin, Prametide


w/u etiology of dka

R/o infx (blood/urine cultx, cxr, U/A), Toxicology (amphetamines), Amylase/Lipase (pancreatitis), EKG (if age > 30, q 8 hrs along with serial troponins)


Thyroid abnormalities expect during pregnancy

TBG elevated, Total T4 elevated, Free T4 normal


Most common complications of thyroid surgery

Damage to recurrent laryngeal nerve (hoarseness) & parathyroids (hypocalcemia)


Tx proliferative diabetic retinopathy; Tx peripheral neuropathy

Laser photo coagulation; Gabapentin, pregabalin, duloxetine; Also important for both, control glucose level
