Hypothalamus controlling temperature set point is briefly mentioned in Pathoma 2018 edition page 13, Chapter 2 III Cardinal signs of inflammation D. Fever

Pyogenes -> macrophage release IL-1 and TNF -> increased cyclooxygenase activity in hypothalamus perivascular cells -> increased hypothalamus PGE2 -> raised temperature set point

Pathoma 2018 edition page 4 chapter 1 - Cellular Injury - III. Reversible & irreversible cellular injury - B.1.

I had difficulty trying to figure out what hydropic change means though...

bharatpillai  i swear i've done the same question before on uworld/ one of the previous NBMEs and the answer to that was intracellular Ca accumulation. +1
mangotango  @bharatpillai that's also true! Dec ATP >> dec activity of Ca2+ and Na+/K+ pumps >> cellular swelling (earliest morphologic manifestation of reversible cell injury), mitochondrial swelling --- FA, pg 207 Na+/K+ ATPase inhibited >> inc intracellular Na+ >> dec activity of Ca2+/3Na+ exchange pump >> inc intracellular Ca2+ --- this is the same way digoxin works in the heart! +

Does anyone know what are A, C, D? For C not sure if it's pointing to the ribosomes on RER.

(I'm assuming E is glycogen granules based on a comment below!)

vshummy  Synaptobrevin is a SNARE protein. Why they couldn’t just give us SNARE I’ll never know. +36  
yotsubato  Cause they're dicks, and they watched sketchy to make sure our buzzwords were removed from the exam +36  
yotsubato  Oh and they read FA and did UW to make sure its not in there either +29  
soph  This toxin binds to the presynaptic membrane of the neuromuscular junction and is internalized and transported retroaxonally to the spinal cord. Enzymatically, tetanus toxin is a zinc metalloprotease that cleaves the protein synaptobrevin, an integral neurovesicle protein involved in membrane fusion. Without membrane fusion, the release of inhibitory neurotransmitters glycine and GABA is blocked. -rx questions! +5  
qfever  So out of curiosity I checked out B) N-Acetylneuraminic acid It's sialic acid typical NBME +2  
alexxxx30  shocked they haven't started calling a "farmworker" a "drudge" <-- word I pulled from thesaurus. +2  
snripper  "You shouldn't memorize buzzwords. You gotta learn how to think." Lemme pick another random ass word that doesn't have anything to do with critical thinking skills and use it instead. +4  
mw126  Just as an FYI, there are multiple "SNARE" Proteins. Syntaxin, SNAP 25, Synaptobrevin (VAMP). From google it looks like Tetanospasmin cleaves Synaptobrevin (VAMP). Botulism toxin has multiple serotypes that target any of the SNARE proteins. +2

mousie  thanks for this explanation! +  
macrohphage95  can any one explain to me why not lens ? +  
krewfoo99  @macrophage95 Lens are an interal part of the refractive power of the eye. Without the lens the image would not be formed on the retina, thus leading to visual loss +4  
qfever  Do anyone know why not choroid? +1  
adong  @qfever, no choroid would also be more detrimental to vision since it supplies blood to the retina +2  
irgunner  That random zanki card with colobomas associated with a failure of the choroid fissure to close messed me up +7  
mnemonicsfordayz  Seems like the key to this question is in what is omitted from the question stem: there is no mention of vision loss. If we assume there is no vision loss, then we can eliminate things associated with visual acuity (weird to think of in 2 week old but whatever): C, D, E, F. Also, by @hayayah 's reasoning, we eliminate E & F. If you reconsider the "asymmetric left pupil" then the only likely answer between A & B is B, Iris because the iris' central opening forms the pupil. I mistakenly put A because I was thinking of the choroid fissure and I read the question incorrectly - but it's a poorly worded question IMO. +  
mamed  Key here is that it doesn't affect vision- the only thing would be the iris. All others are used in vision. Don't have to know what a coloboma actually is. +1  
azibird  The extra section of that Zanki card specifically says that a coloboma "can be seen in the iris, retina, choroid, or optic disc." Don't you dare talk trash about Zanki! +1
