hello to all, my name is daniel licht, i am a second year medical student at the university of medicine and dentistry of new jersey and, hopefully, a future neurologist. i am interested in this group for personal reasons and because a good friend of mine has parkinson's and has turned to me for advice. advice i give as best as mylimited knowlege permits. i have two questions for whoever can help: 1) what has been the progress of the colorodo fetal tissue implant trial? i understand, or more accurately, it has been rumored, that there has been a problem with patients stroking from the surgery. is this true? 2) there has been a resurgance in the use of pallidotomies, i missed this group's discussion on the subject (i would like to get copies of all that was said)..from what i understand, the latest technique is to clip the ansa lenticularis at the lateral globus. does such proceedure preclude you from having a fetal tissue transplant when and if that proceedure is improved? sorry about the length of the note. i anxiously await response. allbest, daniel ([log in to unmask])
