I have a few questions that I haven't come across in the thread. Thanks in advance:
2.8: One regarding woman with enlarged uterus. What is next stop of establishing diagnosis
measure fsh, tsh, hcg, ultrasound, biopsy. I put ultrasound. Thought it was mole.
If that's the one where it says something about a blue tinged vaginal mucosa, then hCG is the right answer. I guessed at that one, but I had defaulted to the always check to see if pregnant rule.
2.18: Man with cirrhosis who has erectile dysfunction. What is decreased?
estradiol, estrone, fsh, hcg, lh, testosterone. I thought it was lh but my guess it is testosterone.
yes it's testosterone. Alcohol causes increased aromatization of testosterone to estrogen, leading to gynecomastia, spider anigomas, etc. Decreased testosterone as a result and its assoc. effects.
2.39: man presents to ed with bruit in lower abdomen. what is going on?
compression fracture, herniated disc, leaking aortic aneurysm, leaking renal artery aneursym, perforated rectum, perforated sigmoid colon. Thought it was renal artery aneurysm
leaking aortic aneurysm
3.16: 2 month old dies of meningitis (mycobacterial infection). What is going on?
Brutons agammaglobulinemia, leukocyte adhesion deficiency, complement deficiency, ifn-gamma receptor problem. I put leukocyte adhesion deficiency.
