Adrenal glands (Pathology) Flashcards
3 layers of cortex and what they excrete
glomerulosa - mineralcorticoids “salt”
fasciculata - glucocorticoids “sugar”
reticularis - estrogens and androgens “sex”
adrenal medula excretes
Epi & NE
trunkal obesity, moon facies w/flushing, acne, buffalo hump
cushing syndrome
Cushing disease
pituitary cushing syndrome
characteristics of hyperaldosteronism
htn & hypokalemiaa
aldosterone-secreting cortical adenoma causes
Conn syndrome
hypertension & hypokalemia
usual significance of cortical adenomas?
often insignificant (insidentaloma)
21-hydroxylase or 11-beta-hydroxylase deficiency leads to
adrenogenital syndrome
adrenogenital syndrome
impaired synthesis of both cortisol and aldosterone
increased secretion of adrenocorticotropic hormone, resulting in adrenal hyperplasia and increased synth of testosterone
Most common cause of Waterhouse-Friderichsen Syndrome
N. meningitidis
typical appearance of adrenal glands in Waterhouse-Friderichsen syndrome
big bag of blood
3 causes of acute adrenal insufficiency and outcome
N. meningitidis in Waterhous-Friderichsen syndrome
Sudden withdrawal from corticosteroids
patients with chronic insufficiency with sudden stress
Often fatal
chronic adrenal insufficiency
addison’s disease
addison’s disease characteristics
weakness, nausea, weight loss, hypotensive. pigmented skin.
hyponatremia, hyperkalemia, metabolic acidosis, hypoglycemia, low cortisol,
failure to respond to stimulation tests by increasing cortisol output
