Q

Marker for monitoring papillary thyroid cancer

A

Serum thyroglobulin and thyroglobulin antibody

17
Q

Treat type 2 amiodarone induce thyrotoxicosis and symptomatic thyroid tenderness from thyroiditis

18
Q

Teprotumumab is a monoclonal antibody to insulin like growth factor 1 receptor, uses to treat

A

Moderate to severe graves ophthalmopathy

19
Q

Treatment of primary hyperparathyroidism and concurrent osteoporosis, unable to undergo surgery

20
Q

Pituitary infiltrative disorder caused by sarcoidosis and Langerhans cell histiocytosis

A

Can cause deficiency of anterior pituitary hormones and arginine vasopressin deficiency

21
Q

How many types of amiodarone induce thyroiditis and how to differentiate

A

Type 1 AIT on graves and thyroid nodules, treat with methimazole
Type 2 AIT called destructive thyroiditis treated with glucocorticoid
Differentiate by ultrasound. Increase vascularity is type 1, decrease vascularity is type 2

22
Q

Which circumstances to check free t3

A

1: evaluation of thyrotoxicosis to identify isolated t3 toxicosis
2: assess the severity of hyperthyroidism and response to therapy
3: to potentially differentiate hyperthyroidism from destructive thyroiditis

23
Q

Contrandication of raloxifen

A

High risk for fracture and history of cardiovascular disease

24
Q

Contraindication of romosozumab: mixed anabolic and antiresorptive effect

A

History of cardiocascular disease

25
Teriparatide is an anabolic agent used for postmenopausal women at high risk osteoporotic fracture. If start subsequent to denosumab discontinuation, it will stimulate the bone resorption associated with denosumab
26
Positive plasma aldosterone concentration/plasma renin activity in primary aldosteronism
Ratio greater than 20 with plasma aldosterone concentration of at least 15 ng/dl
27
When do we consider pheochromocytoma
When nodule density is more than 10 hounsfield units
28
How is plasma renin activity on patient uses acei and arb
Plasma renin activity is elevated. If pra is low, suspect primary hyperaldosteronism
29
Confirmatory test for primary hyperaldosteronism
Aldosteron measurement after oral sodium loading or saline suppression test. Aldosteron level need to be suppressed after loading with sodium
30
How to distinguish renal and extrarenal of potassium loss
Check 24-hour potassium creatinine ratio or spot urine potassium creatinine ratio. If less than 13 meq/g it is extrarenal.
31
In acromegaly, if IGF-1 is elevated, what to do next
Oral glucose tolerance test to confirm the diagnosis
32
How high is GH after oral glucose tolerance test to diagnose
Normal is less than 0.2 ng/ml Diagnostic is more than 1 ng/ml
33
Aldosterone also has direct inflammatory and fibrotic effects
