Today is a returning guest, Dr. Michael Hughes. In our discussion we talk about 2 topics. One is on the kidneys and how it affects scleroderma patients and the 2nd topic is on neurological problems and neuromuscular manifestations associated with scleroderma. It was another great conversation and I learned so much. For more background information on Dr. Hughes, you can either go back to episode 39 or go to my website.
