Endocrine Flashcards
Electrolyte abnormalities with adrenal insufficiency
Hypercalcemia
Hyperkalemia
Hyperphosphatemia
Hyponatremia
Major biochem change in adrenal insufficiency besides electrolyte changes
Azotemia
CBC change associated with hypothyroidism
Normocytic normochromic nonregenerative anemia
Biochem change in hypothyroidism?
Hypercholesterolemia
CBC change in hyperthyroid cats
Polycyhemia
Biochem change in hyperthyroid cats
Increased ALP, ALT, AST
Effect of hyperthyroidism on serum fructosamine in cats
Lower than normal
What stimulates glucagon release?
Hypoglycaemia
What does glucagon do?
Stimulates hepatic glycogenolysis and gluconeogenesis -> increases blood glucose
Lipolysis and ketogenesis
2 proteins measures for long-term blood glucose monitoring
Glycosyation of Hb
Fructosamine
What is the effect of aldosterone on renal electrolyte excretion?
Increased reabsorption of sodium
Increased excretion of potassium
Which type of hyperadrenocorticism does not suppress with a high-dose dexamethasone suppression test?
Adrenal tumours
Which type of hyperadrenocorticism does not suppress with either high or low dose Dex suppression test?
Adrenal dependent
Which is the best test to detect iatrogenic hyperadrenocorticism?
ACTH stim.
What causes hyponatremia and hyperkalemia in hypoadrenocortisism?
Lack of aldosterone
