surprisingly, I actually learned this from the Magic School Bus when I was a kid. That's the only reason I got this right. Thanks Ms. Frizzle! :D

Why is it not ovarian follicle cells? I thought the female analog of Sertoli and Leydig is theca/granulosa cells.

colonelred_  Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen. +2  
brethren_md  Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +1  
sympathetikey  Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +1  
s1q3t3  Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +1  
masonkingcobra  Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +  
mcl  Wait, but did anyone mention that females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen??? +10  
mcl  But seriously though, pathology outlines says sertoli-leydig tumor "may be suspected clinically in a young patient presenting with a combination of virilization, elevated testosterone levels and ovarian / pelvic mass on imaging studies." As for follicle cell tumors, granulosa cell tumors usually occur in adults and would cause elevated levels of estrogens. Theca cell tumor would also primarily produce estrogens. Putting the links at the end since idk if they're gonna turn out right lol Link pathology outlines for sertoli leydig granulosa cell tumor theca cell tumor +6  
bigjimbo  LOL +  
fallenistand  Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen. +2  
medpsychosis  So after doing some intense research, UPtoDate, PubMed, an intense literature review on the topic I have come to the final conclusion that...... ...... ...... ...... Wait for it.... ..... ..... Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen. +3  
charcot_bouchard  Hello, i just want to add that Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +1  
giggidy  Hold up, so I'm confused - I read all the posts above but I still am unsure - are sertoli-leydig cells notorious for producing androgen? +1  
subclaviansteele  Hold the phone.....Females can get sertoli leydig cell tumors which are notorious for producing androgen? TIL TL;DR - Females can get sertoli leydig cell tumors = high androgens +  
cinnapie  I just found a recent study on PubMed saying "Females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen" +  
youssefa  Hahahahaha ya'll just bored +2  
water  Bored? you wouldn't think so if you knew that females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +  
nbmehelp  I dont get it +  
redvelvet  how don't you get it that females can get Sertoli Leydig cell tumors, which are notorious for producing lots of androgen? +  
drmomo  what if this means..... females can get Sertoli Leydig cell tumors, which are notorious for producing lots of androgen +  
sunshinesweetheart  hahahaha this made my day #futurephysicians #lowkeyidiots +  
sunshinesweetheart  @medstruggle look up placental aromatase deficiency (p. 625 FA 2019), it would have a different presentation +  
deathbystep1  i am sure i would ace STEP 1 if i only knew that females can get sertoli-leydig cell tumors, which are notorious for producing lots of androgen +  
noplanb  Wait... I might actually never forget this now lol +  


submitted by mousie(83),

is this subacute endocarditis associated Membrano-proliferative GN?

jus2234  The question describes how he had a strep infection 15 days ago, and now this is poststreptococcal glomeruloneprhitis, which can also be described as proliferative glomerulonephritis +7  
seagull  The question would be too fair if it just said PSGN. Instead we need to smell our own farts first. +28  
yotsubato  And they used terminology NOT found in FA +5  
water  who said they were limited to FA? +1  
nbmehelp  FA uses the common nomenclature and the fact most of our other resources use the same nomenclature for this, I think we can agree that is is the accepted terms. If they're gonna decide not to use the nomenclature that most medical students are taught then they should provide their own study materials at that point for us to use. The test shouldn't be this convoluted for no reason. +1  


Can someone explain why does this patient have hypokalemia?

colonelred_  Catecholamines activate the Na/K pump, which will drive K inside. +5  
trazabone  Read online that catachelamines are released following tonic clonic seizures. Besides that, BP of 180/100 could indicate that catecholamines are circulating. +1  
fulminant_life  This mechanism is why giving albuterol for hyperkalemia works +3  
nbmehelp  Why does this guy have increased catecholamines tho +  
johnson  His SNS activity is seriously increased --> increased catecholamines. +  
nbmehelp  Why is his SNS activity increased? Is the BP literally the only hint? +  
youssefa  Alcohol withdrawal creates a hyper- catecholaminergic state + Seizures do that as well. +1  
water  My best guess is that withdrawal puts the body in a state of stress (same for seizures) and with stress you have release of catecholamine which we'll see in the BP and the hypokalemia. +
