DR. BOLIN, I am so grateful for you. You are a natural teacher. Sometimes I wish you would make the videos a little longer. But just know that you are well appreciated for taking the time to share your knowledge about medicine. Thank you
Dr Bolin thank you very much for all this effort you are putting into these videos...you have been of great help for thousands of medical students and residents!! In 21:41 do you mean 'erythema marginatum' instead of 'erythema migrans'?
