Welcome to the Twitter account for the WVU School of Medicine MS2 Pathology801 course! Please read our guidelines for participation: https://t.co/wODcZKnUzE
The best answer option here is Diabetes Mellitus. Cigarette smoking certainly increases the risk of death for every PPD. For brief historical perspective on DM "equivalency" to CHD see https://t.co/mi9iNWKsGk
Pathology questions return! Which of the following modifiable risk factors for atherosclerosis doubles the risk of myocardial infarction and is considered a coronary heart disease risk "equivalent"?
If we are looking at a young patient with an infection (cold AIHA/agglutinin disease), often antibody titres are rather high — then, acutely, you can see more intravascular hemolysis (schistocytes).
Cold/IgM-mediated will be positive for C3. Even still, it’s more common to see this chronically in older adults; since it’s chronic, again, mostly extravascular.
I am young kid plagued by a bacterial illness that is giving me diarrhea and causing my RBCs to lyse intravascularly. I’m looking a little yellow, and my urine appears dark. My platelet count is 25 k/uL, and my creatinine level is 5.94 mg/dL. What condition do I likely have?
Anemia of chronic disease also would be more of a production issue. The issue here is iron sequestration, where iron is around but not readily available because it's retained by reticuloendothelial cells. Unavailable iron? Decreased hemoglobin synthesis.
Which of the following contributes to peripheral loss or destruction of red blood cells (as opposed to diminished erythropoiesis)? Choose the *best* answer option. @JeffreyVosMD@MBDFlanaganMD
Strong work, everyone! Yes, hereditary spherocytosis is the best answer option here. For renal failure, there'd be decrease epoetin, which would reduce the production of RBCs.
Burkitt is the answer here😃. The other options are small, not intermediate in size. While Mantle Cell in particular can be aggressive, it does not respond well to chemotherapy. Note: Follicular Lymphoma can transform to a diffuse LARGE B-cell lymphoma.
Which of the following is characterized as an intermediate-sized and aggressive B-cell lymphoma that is fortunately very responsive to intensive chemotherapy? HINT: this entity has a relationship with Epstein-Barr Virus. @JeffreyVosMD@MBDFlanaganMD@AShmooklerMD
Correct answer: AB. AB blood (uncommon) means RBCs express A and B antigens, which means that in plasma there are neither anti-A nor anti-B antibodies that could potentially cause hemolysis of recipient A and/or B RBCs.
Hi! I'm a blood donor. You really would appreciate my blood -- especially my plasma, which is universally accepted by all because I do not offer antibodies to A and B antigens present on red blood cells. Unfortunately, though, I'm not commonly found. What's my blood type?
Note how two of the answer options connect to a particular cell line: CD38 & CD138 (plasma cells).🧐 In a board exam situation, you can likely rule-out both answer options and increase your chances of getting to the right answer.😉
CD20 is characteristically absent from plasma cells. Other markers including CD19 and the markers more specific to plasma cells -- CD38 and CD138 -- are present on plasma cells.
[3/n] Thromboxane A2 does contribute to platelet activation. However, most commonly you'll encounter acquired defects associated with exogenous aspirin administration.
You are a molecule essential for thrombosis. Your function is to participate in a series of activation steps. Your absence is caused by a common X-linked disorder. Which of the following best fits your description? @WVUMedSchool@AShmooklerMD@MBDFlanaganMD@JeffreyVosMD
[2/n] von Willebrand Factor is a good thought, but this participates in the adhesion step of primary hemostasis. Furthermore, von Willebrand Factor disorders (von Willebrand Disease) exhibit an autosomal inheritance pattern most commonly dominant and less so recessive.
