Dear nbaker: I'm new on internet and have no idea what I am doing. but.....it wasn't a CA hospital working on implants is China..it was Robert Iacono who took patients to China from here in the days of great controversy regarding foetal implants. Dr. Iacono is a splendid neurosurgeon who happens to be very interested in all phases of Parkinsons including medication. He practices at Loma Linda U and is doing many many pallidotomies there. What is the CO testing in Lubbock you mentioned? Have you met Ava Crowder a parkinsonian who is an ambassador for the American Parkinson Disease Association. If you get this it will be a miracle. I should have addressed this to everybody as there might be something of interest, but once I hit the key to answer to your note it was too late - or is it? Regards, Barbara Yacos
