What is the neoplastic chondrocytes filling lacunes?

mumenrider4ever  I think that's a chondrosarcoma (tumor of malignant chondrocytes, found in the pelvis, proximal femur and humerus, FA 2020 pg. 465) +1

Was anyone thinking about answer choice E- PTH hormone production? I was in between a Vitamin D and Calcium deficiency with the no milk. I ended up going with vitamin D (thank you sketchy) but couldn't rule out a calcium deficiency in my mind.

Formation of granulation tissue (Day 3-7 of healing): Fibroplasia leads to the synthesis and deposition of type III collagen. Growth factors (ie- VEGF) from fibroblasts and epithelial cells promote angiogenesis. (Credit- Amboss)

Pyridostigmine is an acetylcholineserase inhibitor used long term for MG (Sketchy). Put pyridostigmine as my answer because it does treat MS. But yes baclofen is a classic anti-spasm drug.

Per boards and beyond, in the lateral pons is there is the spinal V nucleus which carries contralateral pain and temperature. Knowing that + CN V arises it in the pons, I went with pons. The only other option I had left not crossed out was cerebral hemisphere but that seemed to broad.

vivarin  BB also said not to use the rule of 4's to localize CN V to the pons so that's why I crossed it out... +

"disproportionate reduction in the peak expiratory flow rate or maximum minute volume compared with the forced expiratory volume in one second (FEV1). It should be noted, however, that there can be a significant loss in airway cross-sectional area before the textbook flattening of the inspiratory or expiratory loops are visualized."

mamed  google fixed upper airway obstruction - the spirometry curve shows decreased inspiration and expiration. A lower airway obstruction just blunts expiration. Extrathoracic blunts inspiration. +

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 +11  
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. +2  
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

confused why this is not autonomic dysfunction or hyponatremia due to sweating and why is this orthostatic hypotension?

mamed  Not sure if this is correct thinking but how I got this right was: 1. She is hypovolemic 2. Likely retaining salt so water follows (ADH or just renal dynamics in general). This is how I ruled our hypokalemia and hyponatremia 3. If she is hyponatremic b/c sweating then why wouldn't she also be hypokalemic? so both have to wrong because both can't be right 4. Volume depletion ==> orthostatic hypotension +1  
blah  I thought that orthostatic hypotension was more of a chronic condition, but I fooled myself into believing that. +  
cbreland  I completely read over the initial BP measurement and picked the wrong answer (mostly b/c of that). Test in 4 days lets get it! +3

tallerthanmymom  Just remember that E.Coli and Bacteriodes Fragilis (sp?) are the 2 main gutys that cause intraperitoneal infections from the gut. +6  
bharatpillai  Why not citrobacter though? +7  
mamed  Common organisms involved in gangrenous and perforated appendicitis include Escherichia coli, Peptostreptococcus, Bacteroides fragilis, and Pseudomonas species (UpToDate) +5
