Q

How do you diagnosis acromegaly?

A

measure IGF-I levels and if elevated test glucose intolerance test and GH measure and if inadequately suppressed then do pituitary MRI to find mass if none then do chest and abd CT to find extrapituitary cayse

Q

What tests would you use to assess adrenal fn?

A

Measure urinary hormone or degradation products- 24 hour collection

Dexamethasone suppression test (corsitol levels should decrease if HPA is normal and ectopic ACTH tumors do not respond)

Metyrapone Stimulation Test (inhibits cortisol via inhibition of 11-beta hydroxylase)

CRH Stimulation Test (excessive rise in ACTH in corticotroph tumors but not in ectopic ACTH producing tumors)

Q

Patient is unsure if he has type 1 or type 2 diabetes what test should you order?

A

GAD ab because 90% of type 1 are positive for GAD

A

80-130

36
Q

Patient has FH of hypoglycemia and thinks she is hypoglycemic as well. What test do you order?

A

serum glucose test when she is symptomatic because insulin levels will be high even though blood glucose is low

37

Whipple’s triad

A

hypoglycemia sx, low blood glucose, reversal of sx when blood glucose normalized

=hypoglycemic

38
Q

What is the MC cause of Addison’s Disease in the US?

A

autoimmune adrenalitis-

thyroid disease is MC

39
Q

What is the MC cause worldwide of primary adrenal insufficiency?

A

TB or fungal infection

40
Q

Adrenals enlarged with granulomas and caseation

A

TB causing primary adrenal insufficiency

41
Q

ACTH high

Cortisol low

A

primary adrenal insufficiency

42
Q

What should you be concerned about in a patient with primary AI who has a major infection and is subjected to major stress?

A

Adrenal crisis

43
Q

AM cortisol <3

A

Adrenal insufficiency

44
Q

What is the Cosyntropin Stimulation Test?

A

Inject cosyntropin → measure basal, 30 min and 60 min cortisol

Nrml resp: max cortisol >18 ug/dl

adresses adrenal reserve but not direct pituitary/hypothal fn

45
Q

What is MC cause of Secondary Adrenal Insufficiency

A

exogenous steroid use

46
Q

ACTH Low

Cortisol Low

A

Secondary Adrenal Insufficiency

47
Q

What medications must be avoided when testing a patient for primary aldosteronism?

A

spironolactone and eplernone

48
Q

Elevated aldosteronism, normal or elevated renin

With hypertension: renal artery stenosis, malignant hypertension, renin-secreting tumor

A

Secondary hyperaldosteronism with HTN

49
Q

Decreaseeffectivecentralvascularvolume

Hypovolemia, CHF, cirrhosis, nephrotic syndrome

A

Secondary hyperaldosteronism without HTN

50
Q

What is the Best Screening Test for Primary Aldosteronism?

A

Aldosterone and renin

51
Q

How do you determined if ACTH dependent Cushing’s syndrome is primary or ectopic?

A

High dose dexamethasone suppression test

Pituitary will have partial suppression which Ectopic ACTH will have no suppression

or CRH stimulation test
Ectopic ACTH will not stimulate cortisol while pituitary will

52

A

Bradykinin, histamine, prostaglandins

67
Q

Suspected humoral agent with Skin lesions

A

Niacin deficiency

68
Q

If adrenal hyperplasia is due to excess ACTH what zone is affected?

A

zona fasciculata and

zona reticularis

69
Q

If adrenal hyperplasia is ACTH independent what zone is affected?

A

zona glomerulosa

70
Q

Paraganglioma

A

Extraadrenal pheochromocytoma

71
Q

What finding in Neuroblastoma would indicate poor prognosis?

Autoimmune destruction of insulin-producing pancreatic β cells

74
Q

Impaired cellular responses to the physiological effects of insulin

A

insulin resistance

75
Q

Impaired cellular responses to the physiological effects of insulin

A

insulin resistance

76
Q

MC cause of hypercalcemia

A

primary hyperparathyroidism due to enlarged adenoma

77
Q

TSH is normal but free T4 is low what is most likely diagnosis?

A

central (or secondary) hypothyroidism

78
Q

Low TSH

Low FT4

A

central hypothyroidism

OR

use of T3 product- won’t need FT4 or TSH so they will be low
