Endo Flashcards
(75 cards)
treatment for prolactinoma MOA
Dopamine agonists (like bromocriptine/cabergoline)
or transsphenoidal resection
Adverse effect of anti-psychotics on prolactin
increase prolactin secretion (most anti-psychotics work via antagonizing dopamine)
treatment for Acromegaly/ Gigantism (2)
- somatostatin analogs (like Octreotide)
2. GH-R antagonist (pegvisomant)
treatment for central DI and nocturnal enuresis
desmopressin (ADH analog)
enzymes inhibited by Propylthiouracil
- thyroid peroxidase
2. 5’ deiodinase
enzyme inhibited by methimazole
thyroid peroxidase
Which endocrine hormones signal through cAMP? (12)
“FLAT ChAMP + cal+GHRH+glucagon”
- FSH/LH/TSH/hCG (these are all derived from same molecule)
- ACTH/CRH
- ADH(V2-R)
- MSH
- PTH/calcitonin
- GHRH
- Glucagon
Which endocrine hormones signal through cGMP? (2)
“BAD GraMPa” (GraMPa=GMP)
- BNP/ANP
- E’D’RF (NO)
- think vasodilators
Which endocrine hormones signal through IP3 (Gq)? (7)
“GOAT HAG”
- GnRH
- Oxytocin
- ADH (V1-R)
- TRH

- IGF-1
- FGF
- PDGF
- EGF
Which endocrine hormones signal via Non-receptor tyrosine kinase? (6)
JAK/STAT pathway "PIGGlET" 1. Prolactin 2. Immunomodulators (cytokines, IL-2, IL-6, IFN) 3. GH 4. G-CSF 5. Erythropoietin 6. Thrombopoietin
treatment for Pheochromocytoma?
MOA
Phenoxybenzamine (also has 16 letters like Pheo)
- irreversible a-antagoist
Follow this with a BB prior to tumor resection
- Never BB before a-angtagonist (always in alphabetical order) to avoid Hypertensive crisis
treatment for Thyroid Storm? (4)
Treat with the 4P’s
- BB (propranolol)
- Propylthiouracil

- Potassium iodine
treatment for central DI? (2)
- desmopressin
2. hydration
treatment of nephrogenic DI? (5)
- hydrochlorothiazide (thiazide diuretic)
- indomethacin (NSAID= decrease renal flow)
- amiloride (K-sparing)
- hydration
- remove offending agent (like lithium)
- scare body with volume depletion to cause increase proximal tubule saline reabsorption
Treatment of SIADH ?
- fluid restriction
- salt tablets
- IV hypertonic saline
- diuretics
- conivaptan
- tolvaptan
- demeclocyline
treatment for Hypopituitarism?
Hormone replacement
corticosteroids, thyroxine, sex steroids, HG
treatment for Diabetic ketoacidosis?
IV fluids
IV insulin
K to replace intracellular stores
Glucose as necessary to prevent hypoglycemia
Treatment of hyperosmolar hyperglycemia non-ketotic syndrome?
aggressive IV fluids
insulin therapy
treatment for glucagonoma
ocreotide or surgery
treatment of insulinoma
