On the q on chronic pancreatitis how is phospholipase A2 wrong? BNB says word for word pro-phosphopilase A2 is an enzyme from pancreas.
Lipase is diagnostic of pancreatitis (hence the answer was co-lipase)
Am I missing something here?
Question on 21 hydroxylase? How is the na level normal? Shouldn’t 11b hydroxylase be answer when corticosterone is made? No mineralocorticoid is made when you have 21 deficiency.
17-hydroxyprogesterone is diagnostic of 21-hydroxylase deficiency (not sure if you’re referring to this one)
lastly the q on the dexamethasone administration why no change no change in ACTH and cortisol? Doesn’t he have adenoma of fascicularis and dexamethasone should inhibit cortisol?
A tumor of that is secreting a ton of cortisol will not be inhibited by another, exogenous cortisol analog (-sone drugs). The patient has zero ACTH levels basically so the tumor has a mind of its own and is blasting away. Tbh, I don’t think anything would suppress it.
Thx If you can help out with these. I went through other q’s and I guess I was wrong. had a rough morning so it was a rough start hopefully gonna be smooth next week lol
