btl_nyc  The increased testosterone is metabolized by granulosa cells to estrogen and by adipose tissue into estrone. Both feed back on the hypothalamus to inhibit FSH & LH secretion, but FSH is much more sensitive to feedback inhibition than LH, causing an increased LH/FSH ratio. +1

someduck3  Is this the best approach to all of the "strongest predisposing risk factor" type questions? +  
drdoom  There is a town of 1,000 men. Nine hundred of them work as lawyers. The other 100 are engineers. Tom is from this town. He rides his bike to work. In his free time, he likes solving math puzzles. He built his own computer. What is Tom's occupation most likely to be? Answer: Tom is most likely to be a lawyer! Don't let assumptions distract you from the overwhelming force of sheer probability! "Given that Tom is from this town, his most likely occupation (from the available data) = lawyer." +4  
drdoom  There is a town of 1,000 spontaneous pneumo patients. Six hundred are tall, thin and male. The other 400 are something else. Two hundred of the 1,000 smoke cigarettes. The other 800 do not. What risk factor is most strongly associated with spontaneous pneumo? (Answer: Not being a smoker! ... because out of 1,000 people, the most common trait is NOT smoking [800 members].) +4  
impostersyndromel1000  this is WILD! thanks guy +3  
belleng  beautiful! also, i think about odds ratio vs. relative risk...odds ratio is retrospective of case-control studies to find risk factor or exposure that correlates with grater ratio of disease. relative risk is an estimation of incidence in the future when looking at different cohort studies. +  
drdoom  @impostersyndrome I love me some probability and statistics. Glad my rant was useful :P +  
hyperfukus  @drdoom i hate it which is why your rant was extremely useful lol i learned a ton thanks dr.doom! +1  
dubywow  I caught he was thin. The only reason I didn't pick Gender and body habitus is because he was not overly tall (5'10"). I talked myself out of it because I thought the body habitus was too "normal" because he was not both thin AND tall. Got to keep telling myself to not think too hard on these. Thanks for the explanation. +1  
taediggity  It isn't just that this person has Ehlers Danlos and they're more prone to spontaneous pneumo??? +1

wutuwantbruv  Correct, you would not want to give fibrates to someone with recurrent pancreatitis since fibrates increase the risk of cholesterol gallstones due to inhibition of cholesterol 7α-hydroxylase. +  
kernicterusthefrog  FYI @gh889 can't follow your link w/o an NYIT username and password, unless there's a more tech-savvy way around that.. I appreciate the info, though. Niacin rx for familial hypertriglyceridemia w/ recurrent pancreatitis. Now I know.. +2  
impostersyndromel1000  Great points, very in depth knowledge taking place here. Also, familial hypertriglyceridemia (per FA 2019 pg 94) has hepatic overproduction of VLDL so picking this would have been the easiest answer (in retrospect) +2  
hyperfukus  @impostersyndrome1000 literally that's the ONE thing i remembered and i went YOLO lol cuz i was staring for a while +  
osler_weber_rendu  @gh889 I agree niacin is the answer, but even niacin causes increase in HDL. As if getting to the drug wasnt tough enough, NBME puts two of its actions in the options! What a shit question +1  
mtkilimanjaro  I forget where I saw (maybe UWorld), but I always thought increasing HDL is never really a primary form of lipid control. You want to lower the bad cholesterol etc. since increasing good cholesterol wont change LDL VLDL etc. +

keycompany  Additionally, AML is the only answer choice that has multiple blast forms (myeloblasts, promyelocytes, etc.). ALL is characterized by a single blast form (lymphoblasts). +27

keycompany  The answer choices are all of lymphoid origin except for AML and Hodgkin Disease. We know Hodgkin Disease is a lymphoma (not leukemia) and would present with lymphadenoapthy. So the answer must be AML #testtakingstrategies +12

niboonsh  Autosomal Dominant disorders usually present as defects in structural genes, where as Autosomal Recessive disorders usually present as enzyme deficiencies. P450 is an enzyme, so we are probably dealing with an autosomal recessive disorder. furthermore, the question states there was a "homozygous presence of p450.....". In autosomal recessive problemos, parents are usually heterozygous, meaning that 1/4 of their kiddos will be affected (aka homozygous), 1/2 of the kids will be carriers, and 1/4 of their kids will be unaffected. +36  
nwinkelmann  Is this how we should attack this probelm?: First clue stating endoxifen is active metabolite of Tamoxifen should make us recognize this undering first pass hepatic CYP450 metabolism? Once we know that, the fact that the metabolite is decrease suggests an enzyme defect, which is supported by patient's homozygous enzyme alleles. Then use the general rule that enzyme defects are AR whereas structural protein defects are AD inheritance patters. Once we know the pattern, think that most common transmission of AR comes from two carrier parents. So offspring alleles = 25% homozygous normal, 50% heterozygous carrier, and 25% homozygous affected, thus sister has a 25% of having the same alleles as patient (i.e. homozygous CYP450 2D6*4)? +6  
impostersyndromel1000  we had the exact same thought process, so i too am hoping this is the correct way to approach it get reasoning friend +  
ajss  thanks for this explanation, I totally forgot about AR patterns are most likely enzymes deficiencies, this kind of make the question easier if you approach it that way, thanks +
