So did I just get lucky? I just did rule of 4s, bilateral motor meant medial and I interpreted horizontal eye movement as CN6 which is also medial and pons(CNs 5,6,7,8). Couldn't really place the disarthria but medial pons seemed like a good option.

So I didn't remember IPEX but I do know some basic inmuno and the stem sounded like many autoinmune manifestations, so logically a decrease in Treg lymphocytes (which are inmunosuppresive) seemed like the best answer.

FA 19 256

Does the drug SWIM? Phase 1 - small number of volunteers assess for Safety Phase 2 - moderate number of patients, does it Work Phase 3 - large number random assignment, with placebo, any Improvement? Phase 4 - hit the market, any unexpected side effects, can be withdrawn from Market

kpjk  just would like to make a small correction phase 3- not placebo, but a drug already present in market so to test if there is improvement over standard care phase 2- would have the placebo, to see if the drug is actually working thats why i got confused in this question couldnt phase 2 also have randomized,prospective double blinded study +3

Up to 80 percent of aortic aneurysms are caused by "hardening of the arteries" (atherosclerosis). Atherosclerosis can develop when cholesterol and fat build up inside the arteries. ... Elevated blood pressure through the aorta can then cause the aortic wall to expand and bulge.

FA19 pg. 609 (nice)

drdoom  The prevailing rule of American medicine (and law) is individual autonomy. No other person, professional or otherwise, is granted “default access” or privilege to another person’s body—that includes the physician! The physician must receive consent from a (conscious) “person” before they become “a patient”. In the same way, the person (now, the patient) must give consent before anyone else is permitted to be involved in her care—spouses included! +1

usmlecharserssss  how FEV1/FVC is normal i cannot get that +1  
sammyj98  I think this is standard for restrictive lung diseases. In obstructive the airways collapse during expiration so it's hard to expire, but there's a long drawn out end to epiration as little by little it escapes, leading to a decreased FEV1/FVC. In restrictive pt's just aren't able to move and expand their lungs enough, so when they expire it's of a small volume, but there isn't any collapse involved. It's like a normal expiration just with a restricted volume, making the FEV1/FVC normal. +  
spow  @usmlecharserssss In restrictive lung diseases, the ratio is either normal or increased. +  
drzed  And the reason why FEV1/FVC is either normal or increased in restrictive lung disease is very simple: the FEV1 and FVC both decrease because you are restricting airflow, but the FVC will decrease MORE than the FEV1, and thus because the denominator is larger, the fraction either stays normal, or increases slightly Contrast this to obstructive lung disease where you have an obstruction to air FLOW, e.g. the FEV1 will decrease more than the FVC, leading to a low ratio by defition +2  
llamastep1  To add to what @drzed said, fibrosis causes radial traction on the airways therefore increasing FEV1/FVC. Theres a Uworld q on it +

drdoom  Bulimia comes from Greek "ravenous hunger"; the term is a literal concatenation of the words for ox (bous) + hunger (limos).

smc213  Also, when Meningococcal meningitis is treated ... close contacts are also treated prophylactically whereas the others typically are not. There's also a subunit vaccine for n. meningitis due to high infectivity rate especially in crowded establishments. +6

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). +

drdoom  prefer “patients with hx of substance abuse” over more conveniently typed but less redemptive “drug addict” +8  
sugaplum  I don't see why switching her to oral pain meds when she is ready would be incorrect. Clearly she is worried about being on the pain meds, I feel making a proclamation that she has a low risk of addiction would be profiling just because she doesn't have a history. The opioid epidemic also affects people who didn't have a previous history of drug abuse. Just a thought, not trying to push any buttons. Maybe I am thinking to hard about this, but I don't see the clear A vs B line for this question. +30  
nbme4unme  @sugaplum I thought the exact same thing as you and chose the acetaminophen answer accordingly. I maintain that I am correct, my score be damned! +5  
sushizuka  I had a similar question on UW and the explanation stated that the correct answer choice was the only one that addressed the patient's concern and answered her question. The rest were just alternative treatments, so they were incorrect. But I too answered with oral pain meds. +2  
angelaq11  couldn't agree more with you all. I chose acetaminophen because opioid abuse is NO joke. The crisis is still going strong because of answers like this... +1  
houseppary  I ruled out oral acetaminophen because they described in great detail the severity of her injuries, and indicated that she wasn't even fully conscious/aware when she asked this question about opioids. Rather than expose her to more pain, and possibly worsen her long-term pain prognosis, by switching to acetaminophen too early, in this case it makes sense to keep her comfortable because she's very seriously injured and not even fully lucid. It's kind to reassure her in this case. +1  
anastomoses  I appreciate all of the passion for the opioid crisis, and the wording of the answer is definitely not ideal. However, PAIN is also very real, and there is no way acetaminophen alone would cut it in a case like this, not "as soon as she can take medications orally." Maybe I'm lucky to have 6 months in clinicals before STEP or had a mom who just went through urgent spine surgery for breast cancer mets, but there is a time and place for opioids and this is clearly one of them. Thank you for coming to my ted talk. +2  
llamastep1  I agree with anastomoses, cmon guys have you ever had serious pain? oral acetaminophen is NOT enough for that type of pain. +1  
sora  I r/o oral acetaminophen b/c she's post-op for major GI surgeries so you might want to avoid PO meds for a while +  
melchior  As argument against the oral acetaminophen answer choice, it says "switch the patient to oral acetaminophen boldas soon as she can take the medication orallybold" This means you're just waiting for her swallowing inability from the facial fracture surgery to come back, which might not have much to do with her pain, and so it seems somewhat arbitrary. +  
drpee  Maybe logically/clinically A is true, but this seems like a "patient communication" question to me and I could NEVER imagine A being a good way to phrase this point IRL. +1

d_holles  It seems to me that the brain stem problems can all be answered using the Rule of 4s rather than memorizing the actual brain stem histology. +8  
llamastep1  Yeah I think so too! With the right CN12 palsy you already know it has to be medial (factor of 12) and that would be enough to answer this question. The hemiparesis just confirms that its a medial lesion (starts with M). I know many of us like to really understand the concepts not just use these "tricks" but hey if it works it works. +2

external carotid branch supplies the superior parathyroid glands as well........?

yng  Yes the superior part supplied by superior thyroid gland which is a branch of external carotid branch. +  
llamastep1  No they do not, parathyroids are supplied by the inferior thyroid arteries. +8  
suckitnbme  Superior thyroid artery does supply some blood to the parathyroids through anastomoses but the main vascular supply is from the inferior thyroid artery. +

home_run_ball  ^ Above is partially right: Propranolol is non-selective Beta blocker: Beta1 stimulation causes inc HR, therefore blocking it will dec HR and dec Cardiac output Beta 2 stimulation causes vasodilation, therefore blocking it will CAUSE UNOPPOSED alpha1 activation --> therefore increasing total peripheral resistance. +35  
amarousis  so why tf do we give beta blockers for hypertension -.- +5  
dr_jan_itor  I would also add that the patient was previously on an a2 inhibitor (clonidine), which he ran out of. So he is rebounding on that with upregulated a1 receptor activity. Adding labetalol would cause a greater degree of unopposed alpha, increasing tpr +1  
llamastep1  @amarousis They are used for hypertension because the hypotensive effect of the reduced CO is greater than that of the effect of the increase of TPR. Cheers. +4  
hungrybox  @dr_jan_itor Adding labetalol would not cause unopposed α1 because labetalol and carvedilol are α1 blockers in addition to being nonspecific β blockers (great name btw, I love scrubs haha) +2  
mw126  Beta 1 blockade in the kidney (JG cells) would also decrease renin release, which would also help with HTN. FA2019 pg 245 +  
rockodude  @dr_jan_itor clonidine is an a2 agonist not an a2 inhibitor +

sympathetikey  Brilliant. +4  
medschul  Would pheo have a normal resting BP though? +4  
meningitis  I was trying to justify these tricky questions but very true medschul.. It shouldn't have normal resting BP. Sometimes it seems these NBME always have a trick up their sleeve. Im getting paranoid lol +  
nala_ula  The reason why the patient probably has normal HTN is because Pheochromocytoma has symptoms that occurs in "spells" - they come and go. Apparently in that moment, when the physician is examining her, she doesn't have the HTN, but like @meningitis explained, so many adrenergic hormones around leads to double the vasoconstriction when the patient stands up. +7  
meningitis  Thank you @nala_ula for your contribution! Really filled in the gap Iwas missing. +1  
nala_ula  No problem! Thank you for all your contributions throughout this page! +1  
mjmejora  I thought the pheochromocytoma was getting squeezed during sitting and releasing the epinephrine then. kinda like how it can happen during manipulation during surgery. Got it right for sorta wrong reasons then oh well. +  
llamastep1  When she sits in the examination table there would be a normal activation of the sympathetic system from the stress of getting examined which is amplified by the pheo. Cheers. +  
sammyj98  UpToDate: Approximately one-half have paroxysmal hypertension; most of the rest have either primary hypertension (formerly called "essential" hypertension) or normal blood pressure. +

notyasupreme  Damn llama, that is WAYYY too much of an inference. Maybe if they said she was nervous in general or something, but not everyone gets stressed out by a doctor hahaha +
