hungrybox  *other downers: alcohol, benzodiazepines, barbiturates +2  
nwinkelmann  THANK YOU! for the link to the video. this is one thing I've ALWAYS struggled with. +  
qball  I get that this is a good rule of thumb to help narrow down between alcohol and heroin, BUT is still not enough to answer this question. Some key features for depressants (downer) is alcohol (if we are talking mild withdraw) - tremors , diaphoresis and delirium (heavy withdraw) . For Heroin - Dilated pupils, yawning and lacrimation are key exam findings. +1

at my uni, we learnt that at lower GFR, loop diuretics still work. That's why you should use them in renal failure. Thiazides would not work with a GFR of <30.

qball  Dang, you actually learned something at your school? Lucky. +9  
lowyield  At our med school they teach us that Thiazide anti-HTN function is primarily from it's direct effects on vasculature rather than it's diuretic effects. Somehow directly affects the vasculature which is not well understood but this is linked to why Thiazides have greater efficacy in African American Populations. That's kinda why i figured it wouldn't be the best diuretic in this case. +

This is a picture of Giardia lamblia… caused by drinking contaminated water with cysts.

Multinucleated trophozoites

qball  This is testing our knowledge in a FAIR way. Why cant there be more questions like this instead of them trying to trick us, have poorly worded questions or have us pick the least shitty answer. End of rant. +1

hungrybox  agreed "granular deposits" rules out MCD (the only other nephrotic syndrome) because MCD is IF (-) +2  
cooldudeboy1  could someone explain why the other choices are ruled out by biopsy? +  
arlenieeweenie  @cooldudeboy1 PSGN does have a granular immunofluorescence, but there is no previous illness or hematuria mentioned so you can rule that out. Goodpasture is classically linear IF since they're antibodies against the GBM. IgA nephropathy is mesangial IF so it would deposit more in the middle. Minimal change wouldn't show anything on IF +2  
qball  I know First Aid states MPGN as a nephritic disease but I think it can present as nephritic or nephrotic syndrome. Of course, the renal biopsy helps give it away but I wouldn't be so quick as to rule out MPGN +1  
taediggity  Totally agree w/ you Qball... I thought MPGN too, but I think Penicillamine makes it Membranous Nephropathy +

qball  Awesome explanation. Now explain it to me like I'm 5. +5  
drdoom  All baby peptides are born in the cytosol. But some baby peptides have a birthmark at their N-terminus. The birthmark tells a special mailman that this baby needs to be delivered somewhere else. If you chop off the birthmark — or erase it somehow — the mailman never knows to take baby to its true home. The end. Now go to sleep or Santa won’t bring your presents. +27

pg32  Nice explanation, but can anyone clarify how we know from the question that we are measuring HCO3 rather than dissolved CO2? +1  
qball  @pg32 This question is asking about what accounts for the LARGER amount of co2 and the HCO3 buffer is about 85% of this transport and dissolved C02 is about 5-7%. +1

suckitnbme  This isn't exactly right as males can still be born as evidenced by individuals III 6,9,11. This basically an x-linked recessive disease. A carrier mother can still pass her normal X chromosome to a son (50% chance). It's just that the other 50% chance of passing an affected X chromosome results in death of the fetus in utero. Thus all males actually born will not be affected. +2  
makinallkindzofgainz  @suckitnbme, Correct, but if you're a live-born male, you 100% for sure do NOT have the disease, so the chance of a live-born male "being affected" is 0. +3  
spow  @suckitnbme it's not X-linked recessive, otherwise every single son would be affected and therefore have died in utero. It's X-linked dominant +2

alexb  Great explanation, except that there was a question in NBME 22 in which the prostatic carcinoma was osteolytic. One of the commenters here looked it up and apparently it's like that 30% of the time or something. So I guess you would have to use the high output HF, normal Ca, high ALP, and mosaic pattern to "play odds" as Goljan would say. +1  
qball  At least they were nice enough to put Paget disease because I had no idea what osteitis deformans is. +1  
drzed  USMLE seems to be moving away from using eponymous names... so it's a good idea to see if there is a descriptive name for diseases. For example, they don't use the word "Wegener" anymore if you have noticed, since it turns out that guy was a nazi. So now they call it by what it is -- granulomatosis with polyangitis. +2

gabeb71  To add to ^ It is widely used (though off-label in many countries including the United States) in the treatment of hyponatremia (low blood sodium concentration) due to the syndrome of inappropriate antidiuretic hormone (SIADH) when fluid restriction alone has been ineffective. Physiologically, this works by reducing the responsiveness of the collecting tubule cells to ADH. The use in SIADH actually relies on a side effect; demeclocycline induces nephrogenic diabetes insipidus (dehydration due to the inability to concentrate urine). +13

submitted by rainlad(20),

my approach to this question was to eliminate all the answer choices that mentioned specificity or sensitivity, since the data here did not provide information about any sort of screening test.

that left me with two possible answer choices: I eliminated the one about consistency of other studies, since no other studies were mentioned in the question stem.

not sure if I oversimplified things, but it led me to the right answer!

dentist  So, Cholera is also p2p but Mening is more likely? +1  
usmlecharserssss  in cholera people to water => water to people +  
qball  Remember the fire sprinklers from Sketchy for M. Meningitis. as respiratory droplets are the easiest to transmit from person to person. +  
drschmoctor  but the poop water comes from people so.... +1  
llamastep1  Respiratory dropplets is easier than fecal-oral tho +1  
lowyield  Can also reason that n. meningitidis is common in college students because they live in close quarters which suggests high rate of transmission even amongst immunocompetent individuals +1  
peridot  I can see why fecal-oral can seem like person-to-person transmission. What helped me reason it was that in countries with lots of cases of cholera, the primary reason is lack of water sanitation. Even when you google cholera, you get pictures of people collecting dirty water and how the WHO is aiming to reduce cases of the disease by improving water sources. Therefore it's more of a systemic/environmental problem rather than the fact that one person accidentally touched another person's poopy parts and then transmitted it to their own mouth, making this less of a person-to-person thing, especially when compared to another answer choice such as Meningococcal meningitis. +  
bbr  To add, think of the water in cholera as a reservoir. The bug is going to hang out there between infecting another person. In meningitis it seems we are going from 1 persons saliva to another. Without much of a reservoir inbetween. (might be using the word reservoir incorrectly). +
