Thomas A. Medsger, Jr., MD
University of Pittsburg School of Medicine
I just found a recent presentation by Dr. Thomas Medsger on the clinical significance of autoantibodies in systemic scleroderma. This is a slide show presented to rheumatologists in Arizona in 2014 and is the best summary of current research on this topic that I have ever seen. Dr. Medsger is considered by most researchers to be one of the top scleroderma researchers in the world. (He is also an informal advisor to my research group.)
Please note that this is a very technical presentation meant for rheumatologists, but there is still a lot of information that you may find interesting even without a medical background. If you have specific questions, I will be happy to answer any that I can.
