Flashcards in clinical overview of hypothalamus and pituitary Deck (18):
what are hypothalamus and pituitary disorders due to?
hypersecretion, deficiency, hormone resistance
what is the cushing syndrome hormone level throughout the day?
increased midnight cortisol compared to normal but normal in mornings
hormone hypersecretion and deficiency is due to what?
neoplastic, autoimmune, latrogenic, infectious/inflammatory rxn
what are the hormones released by the anterior pituitary gland
thyroid stimulating horsmone (TSH)
Follicle stimulating hormone (FSH)
luteinizing hormone (LH)
what is the mechanism of the anterior pituitary release its hormone?
through blood circulation
What hormones are produced in the posterior pituitary
what is the mechanism for the posterior pituitary gland to deliver their hormones
most common benign neoplasm--50% of all functioning pituitary tumors are hyperprolactinemia
Female: amenorrhea, galactorrhea, infertility mild hirtuism
- diminished libido, visual loss, headache, gynecomastia
ACTH deficiency: autoimmune disorder directly affecting adrenal gland and start producing less cortisol, therefore feedbacks to pituitary to make more ACTH
Primary adrenal insufficiency: fatigure, weakness, anorexia, nausea, vomiting, weight loss, low BP, depression, hypoglycemia
Tx for addison's disease
glucocorticoid; hydrocortisone or prednisone
what is the adolescent form of Acromegaly?
What is the common surgery to remove adenoma/ tumors in the pituitary gland?
what is the most proper treatment for Acromegaly?
growth hormone antagonist, surgery, somatostatin analogues, radiation
what test would you need for patient that has prolactinoma
What are the two signals that control release of hormones
Releasing hormone produced by hypothalamus and feedback from target organ
Which hormone has greatest levels at onset of sleep at nigh
what is one thing you must know when testing for hypothalamus/pituitary disorder
