Why could this not be extravascular hemolysis? In FA it says acute hemolytic transfusion reaction can be due to ABO incompatibility or extravascular hemolysis.

niboonsh  because extravascular hemolysis is associated w jaundice. Intravascular hemolysis would have hemoglobinuria but that's not an answer
niboonsh  i mean that is the answer lol
krewfoo99  According to pathoma: Intrvascular haemolysis will lead to haemoglobin binding to haptoglobin. This complex will travel to the kidneys and be excreted. This will lead to red colored urine and haemosiduria (Note: This can also lead to acute tubular necrosis) Extravascular haemolysis is when macrophages break down the RBC. Then the Haeme is converted to biliverdin then bilirubin and conjugated in liver, and then excreted.

The patient has a leaking berry aneurysm --> this leads to a subarachnoid hemorrhage (or leakage into subarachnoid space) --> acute SAH can lead to decreased absorption and movement via arachnoid villi

zbird  So this patient has a leaking berry aneurysm which undergone to surgery and repaired but in two days she developed widening of the SA space which could be explained by increased CSF production but a decreased in absorption, which is due to blockage of the arachinoid granulations by the leaked red and white cells therefore there is a decreased movement of the CSF via the arachinoid villi

"Desmosome (Macula adherens) - A cell-to-cell connection that provides structural support with intermediate filaments, particularly in tissues that undergo mechanical stress (e.g., skin, gastric tissue, bladder). Connects keratinocytes in the stratum spinosum of the epidermis." - AMBOSS

sympathetikey  This is why I was looking for some answer indicating keratinocytes in the stratum spinosum...instead they just gave a bunch of bs choices. +9  
roygbiv  I'm confused because I also know that S. aureus cleaves desmoglein in the stratum granulosum, so why is it specifically this answer? +  
duat98  desomosomes connects cells to cells. hemidesmosome connects cells to basement membrane. +
