They weren't dr. iacono's data as published in a journal. i think i'm beginning to forget what the point of this was. in any case i just saw a new article in 'neurosurgery', vol 35, no. 6 p. 1126 , dec 1994. a group in switzerland has, instead of lesioning the site in the pallidum, implanted electrodes that deliver a constant current to the site. (this is an established methodology(at least to some extent)). this was done in 3 patients who all showed great improvement similar to that seen in pallidotomies. at up to 1 year there was no regression. the benefit of this is that no tissue is destroyed, and it is reversible. bad points are that you ahve an electrode and power supply inside you. this is yet another published report in a reviewed journal, supporting the concept of a pallidotomy. --- Seth L.
