Hematology Review Questions - CRASH! Medical Review Series

Great video and great job... In question 16 you mentioned how LMW heparin was used instead of UFH to reduce instances of HIT. The pathogenesis in HIT is antibodies due to PF4 which is a platelet factor. When HIT develops, there is cross reactivity to LMW heparin too, so we use DTI like bivalirudin and lepirudin. In a normal patient, we could choose between any of the two. However, in patients in Renal failure we choose Bivalirudin since it is hepatically metabolized and in patients in Hepatic failure we choose Lepirudin since it is metabolized in the kidneys.

Very helpful, case studies are the most challenging for us, especially with hematology. Thank you so much.

Thank you so much as always!!! I'm a Patreon supporter! You're freaking awesome.

Question #5: Stool quaiac can lead to false negatives as colon cancers don't always bleed. Would order a colonoscopy and skip the guaiac.

Thank you Paul. For number 2, I also eliminated BSS based on the fact that it is less common than vWF. But I think BSS is also normally associated with low platelet count (correct me if I'm wrong)

Omg I'm so happy I found channel. Thank you

Thank you for posting this video! Very helpful!

thank you so much, these videos are very helpful.

Thank you I needed this for my exam preparation😊

Answer to Question # 17 --- D is a better answer . IV Vancomycin + Aztreonam has broader coverage compared to IV Amp+Gent . The latter combination might be good for urosepsis or listeriosis where as the former combination also covers MRSA/MSSA in addition to gram negative rods and is a better empiric choice .

Thanks for your great videos! Extremely beneficial!

thank u so much for ur time n great work

In the UK, with regard to Q5, we would not do a stool guaic test (focal occult blood test) due to high false negative rate, so colonoscopy and endoscopy is usually performed in any older male with IDA. Great video!

Amazing video! Thank you very much!

very very helpful!!!!! Thanks alot.

Thank you very helpful, love from Boston!

Thanks paul great work indeed

Any updates on whether or not to use LMWH in the event of HIT, Dr. Bolin?

Thank you my dear Paul
