joonam  Hey bro, thank you so much for your contributions on these free 120 questions. Your advice on test taking strategies for step 1 have been very helpful. +23
luciana  "Elaborated enzymes by H. pylori may also contribute directly to epithelial cell injury. Ammonia produced through urease activity may be toxic to gastric epithelial cells. H. pylori protease and lipase degrade gastric mucus and disrupt the phospholipid-rich layer at the apical epithelial cell surface, allowing for cell injury from back diffusion of gastric acid." https://www.ncbi.nlm.nih.gov/pubmed/9394757 +4
luciana  I got tricked :( Thought the damage was due to destruction of local somatostatin cells with increased gastrin and acid production... but this is actually the mechanism of duodenal ulcers development related to H. pylori But makes sense, so thats how the somatostatin producing cells are destroyed lol +6
drpee  "Hyperacidity and gastric ulcer development" is also sort of true, but this is hinting at the mechanism for DUODENAL ulcer development from H Pylori. Irritation in the stomach leads to G Cell hyperplasia, increasing acid secrection which causes downstream ulceration. +7
itsalwayslupus  Did anyone else pick the hyperacidity answer just because the correct answer had "local tissue destruction" in it? I figured that H. Pylori was non-invasive, so would not directly damage the tissue it is localized too +8

a1_antitrypsin  Totally agree, and they give you a slight increase in PT instead +1
mambaforstep  yeah but if they gave you an increase in PTT then Hemophilia A could have been a valid answer choice. so they prob showed a nl PTT to differentiate vWF dz from hemophlia A +1
drpee  VWD only sometimes presents with a slightly increased PTT. Don't let those anki facts steer you wrong... Plus all the other answers make no sense. Afibrinogenemia? That means literally no fibrinogin (PT and PTT would be infinitely increased). Hemophelia? Or vitamin K deficiency? Those are coagulation factor disorders so they would present with deep bleeding and large bruising. (Unlike platelet disorders, including VWD, which present with mucosal bleeding, petechiae, and heavy menses). VWD is actually the ONLY one that makes sense. +10
cbreland  I get why it's not afibrinogenemia (which is what I picked), but still don't understand how VWD is right. You have normal PTT and normal platelet aggregation (both of which should be abnormal). Is the only thing leading us to VWD is it being a primary bleeding issue? Again, my answer made no sense, but VWD in this context, seems way out there +4
osteopathnproud  I agree with you @cbreland once I noticed I had to bend lab values for any answer choice then in my head most of them were possible. I took a step back and answer with the most common bleeding disorder, vW disease. Funny thing is when I retook it to check my answers, I had time to overthink and got it wrong. +2
aakb  the anki facts never steer you wrong! my zanki cards say "Low vWF in von Willebrand disease impairs platelet {{c1::adhesion}}" (Gp1B binds to vWF) not platelet aggregation (GpIIbIIIa binds to fibrinogen). additionally it says you can have either a normal or increase PTT. in this case the PT is not increased. It is decreased a little, which I assume is fine esp w an INR of 1.0 +1
lebabs  Shut up +5
justanotherimg  i agree with @drpee , and we also need to keep in mind that hemophilia(x-linked recessive) wont be likely in this patient a 20 yr old woman +1
