Endocrine Flashcards
1
Q
Glucocorticoid Toxicity
A
Cushing Syndrome Diabetes Osteoporosis Glaucoma Peptic Ulcers Neuropsychiatric issues Tertiary adrenal insufficiency Atrophy of adrenal cortex
2
Q
Aldosterone
A
Helps to regulate salt and water balance in the sweat glands and GI tract
Increased aldosterone secretion can occur with decreased sodium and decreased water volume
- high sodium can suppress aldosterone
3
Q
If some one has an aldosterone deficiency
A
- use fludrocortisone it stimulates the aldosterone receptor very avidly
- some synthetic glucocorticoids can have mineralocorcticoid activity
4
Q
Treatment of Pheochromocytoma
A
- give alpha blocker like phenoxybenzamine first
- then give beta blocker
If you give beta blocker without alpha then you can increase the hypertension but having uninhibited alpha vasoconstriction
5
Q
Adrenal Insufficiency
A
- can use metyrapone stimulation test = blocks the last step of cortisol synthesis (11-deoxycortisol –> cortisol)
- Normal response is decreased cortisol and compensatory increased ACTH
- in adrenal insufficiency ACTH remains decreased after test
6
Q
Tesamorelin
A
GHRH analog used to treat HIV associated lipodystrophy
7
Q
TRH
A
increases prolactin secretion
