Endocrine Flashcards
PHPTH (primary hyperparathyroidism) diagnosis?
PTH (normal) with high iCa
What hormone is produced by the anterior pituitary?
Prolactin
Also FSH, LH and TSH, GH, ACTH
What is the fastest acting thyroid hormone?
Which thyroid hormone has the shortest latency until effect?
T3 and also T3
What is the effect of somatostatin?
Inhibits secretion of glucagon (also insulin and gastrin)
Inhibits growth hormone
What is the effect of PTH on the calcium in the kidneys?
Ca resorption
What is a complication/progression of untreated Addison’s?
Increased creatinine
What is the most sensitive test for hyperthyroidism?
Scintigraphy
What is the most likely diagnosis in a patient that is dehydrated, hypernatremic, hyposthenuric, mildly azotemic, hyporephosphatemic and has decreased osmolality?
CDI?
Best treatment for hyperlipidemia and hypertriglyceridemia?
Low fat diet
What metabolite may lead to DKA when low?
Oxaloacetate
What hormone increases GFR?
PGE2
What is an endocrine cause of hypokalemia?
Hyperaldosteronism
What does calcitonin do?
Opposite effect of parathyroid on calcium and phosphate…
What fluid type would you use in a patient with DKA?
Normal saline
What are some prognostic factors for pituitary macroadenoma post radiation?
Resolution of neurological signs?
signs of hyperadrenocorticism take a long time to resolve
What is the most common cause of insulin resistance in cats with diabetes?
Pancreatitis
An other is acromegaly
Giving a PP dog (psychogenic/primary polydypsia) DDAVP leads to what?
Hyponatremia
What blood change is expected with hyperthyroidism?
ALT (elevation?)
Dog with a USG of 1.005. Dog fails to respond to water deprivation or vasopressin. What is the diagnosis?
Nephrogenic diabetes insipidus
What is the most potent stimulator for aldosterone secretion?
Elevated K+
What is the stimulation for ADH secretion?
Osmotic receptors in the supraoptic nuclei.
What is the most common cause for migrating necrotizing dermatitis?
Glucagonoma
Old cat with DKA; given bloodwork showing severe acidosis, mildly low K, very low Cl, severe hyperglycemia, ketonuria/glucosuria; how to treat first
Fluid therapy with 0.9% NaCl (vs insulin)
Interpret a low dose dexamethasone suppression test that shows no suppression at 4 or 8 hours
Consistent with hyperadrenocorticism but cannot tell which type.
