A precipitous drop in Hgb effectively rules out malrotation. Overaggressive anticoagulation is associated with intramural hematoma.

Should be 50:50 here between CaGluc vs. Insulin/Glucose. Peaked T's is a hint that we need to protect myocardium right now.

lindasmith462  I mean I get that Calcium is the right answer (it acts the fastest in 1-3 min) but its supper annoying because you'd be giving insulin and glucose AT THE SAME TIME too - they just take longer to work once you put them in.... +1

Guess one needs to bank on "hilar lymphadenopathy with fever" here.

Lacking upper lobe findings, I got this one wrong.

boeboeboe  Patient likely has primary TB presenting with fever, chest pain. Lower lung fields are affected, but usually nothing seen on CXR. Secondary TB affects upper lobes, and is when cavitary lesions will be seen on CXR +1
kingfriday  There's a uworld question that mirrors this presentation, it got me then- the adenopathy is huge +2

Can anyone explain what they're getting at here? How can bethanechol be indicated and contraindicated?

get full access to all content โ‹… become a member
sniperx3  I think it's because Bethanechol acts on M3 receptors which can treat her urinary problems but it might exacerbate her asthma symptoms since there are M3 receptors on the lungs. +42

lsmarshall  Rectal prolapse through posterior vagina ("rectocele"). https://www.drugs.com/cg/images/en2362586.jpg +8
famylife  "When a rectocele becomes large, stool can become trapped within it, making it difficult to have a bowel movement or creating a sensation of incomplete evacuation. Symptoms are usually due to stool trapping, difficulty passing stool, and protrusion of the back of the vagina through the vaginal opening. During bowel movements, women with large, symptomatic rectoceles may describe the need to put their fingers into their vagina and push back toward the rectum to allow the stool to pass (โ€œsplintingโ€). Rectoceles are more common in women who have delivered children vaginally." https://www.fascrs.org/patients/disease-condition/pelvic-floor-dysfunction-expanded-version +19
usmleuser007  really like the pubic hair.... +5
nnp  why not spasm of external anal sphincter? +
vulcania  After looking it up I think that external anal sphincter spasm would be more associated with rectal pain and maybe fecal incontinence. I chose the same answer because I figured if there was a problem with the rectovaginal septum it would have been noted on physical exam... +1
ajss  I did the same, put sphincter spasm because I thought a rectocele would be found on a physical exam. +

mnunez187  I didn't choose spasm because the stem says there the rectal tone is normal +1

The best I can understand, they're describing endometrial hyperplasia, a result of excess estrogen, a steroid hormone that translocates to the nucleus and binds its transcription factor.

get full access to all content โ‹… become a member
mousie  My exact thinking also! +7
sympathetikey  Ditto. +
meningitis  My thought as well but the answer says: "Binding of ligand to Nuclear transcription factor" and I thought to myself: "Estrogen Receptors aren't transcription factors.. they are receptors with Transcription Factor function that bind to the ER Element and recruit more Transcription Factors". Can anyone explain what I am missing? Am overthinking things? +
criovoly  You are overthinking it, Steroid hormones receptor is found intracellular in the cytoplasm then they are translocated to the nucleus where they regulate gene transcription. HOPE THIS HELPS +6
eve1000  Could this be due to the PTEN gene being linked to endometrial hyperplasia? +
feochromocytoma  The question stem says it's glandular hyperplasia "without" atypia It's just due to increased levels of estrogen causing the hyperplasia +4

I might be the only person on earth who got this one wrong, but regardless:

This review suggests that enchondroma and chondrosarcoma are unable to be differentiated on histology alone. According to Orthobullets:

"unlike enchondroma, most chondrosarcomas have non-mechanical pain (rest pain and nocturnal pain)"

Guess this diagnosis is made on history.

"Excitatory amino acids" refers to glutamate, while "Biogenic" apparently refers to tyrosine, the precursor AA to dopamine and norepi.

sahusema  Amphetamines use the NE transporter (NET) to enter the presynaptic terminal, where they utilize the vesicular monoamine transporter (VMAT) to enter neurosecretory vesicles. This displaces NE from the vesicles. Once NE reaches a concentration threshold within the presynaptic terminal, the action of NET is reversed, and NE is expelled into the synaptic cleft +11

This has been a tough concept for me to get, but I think I'm finally there:

The stem is describing primary adrenal insufficiency, or Addison's.

  • ACTH is being over-produced to stimulate the adrenals to produce cortisol, but they can't respond, either due to atrophy or destruction (TB, autoimmune: DR4, etc.)
  • The first 13 amino acids of ACTH can be cleaved to form ฮฑ-MSH, which stimulates melanocytes, causing hyperpigmentation

jotajota94  Good job! Also, cortisol is involved in maintaining blood pressure. which was decreased in the patient. +7
tinydoc  Decreased Na and increase K+ --- Hypoaldosteronisim Hypoglycemia, and hypotension --- Hypocortisolism so the adrenals arent working ---- adrenal Insufficiency the Hyperpigmentation comes from the increase ACTH as ACTH is from Proopiomelanocorticotropin. SO - increased ACTH also increases a -MSH ---> Hyper pigmentation. +12
hungrybox  thank u for this answer +
bilzcop  Ugh! I misread the question and chose ACTH :( +3

maxillarythirdmolar  Why does this patient have elevated BUN and creatinine?? +3
lovebug  @ maxillaryhidmolar > I don't know exactly. but maybe.. Low hypo-adlo -> our body lose water -> hypo-volemia -> Decreased GFR -> Increased Cr,BUN. If I'm wrong. please correct me. +1

Apart from the line in FA referencing PMN infiltrate in Shigella, there is no way to differentiate here between it and E. Coli. Cheap shot.

get full access to all content โ‹… become a member
merpaperple  As best I can understand, what they are trying to get at is that "EMB stain showing neutrophils" -> "EMB stain NOT showing organisms" -> more likely Shigella than E Coli. If a special culture for an organism (e.g. EMB for E. Coli) shows no organisms but only inflammatory cells, i.e. neutrophils, that means that organism is not present. If that's the point here it's kind of a trick question, as we all would have gotten it right if they had just said "EMB showed no organisms." I guess the takeaway is that the point of a special culture is binary - you are looking for a specific organism, and it is either there or it isn't. +1

dr_jan_itor  Why should he avoid eating excessive starchy foods? To avoid gaining weight? It doesn't matter what macronutrients he eats if they are calorie controlled. +2

beeip  Loss of negative feedback from resected ovaries leads to gonadotroph hyperplasia. +2
halux  so, the explanation is that in the absence of Estrogen negative feedback inhibition to LH and FSH, this leads to Gonadotrophs Hyperplasia at the Pituitary resulting in elevated LH and FSH secretion levels? I get busted by this one :/ Thanks in advance! +14
nala_ula  @halux exactly, there's no negative feedback telling them there is an increase in the hormones (since there are no ovaries) so gonadotrophs work in overdrive to keep stimulating the gonads via FSH and LH. +1
