In the article "Struggle Over Online Cancer Service Spurs Larger Medical Ethics Debate" (F. Hoke, The Scientist, April 3, 1995, page 1), Dean Mouscher was insufficiently identified. In addition to being a Chicago options trader in Chicago, he is clinical trials director for the Houston-based clinic of Stanislaw Burzynski, whose experimental and controversial antineoplaston therapy Mouscher feels extended and improved the quality of his father's life. Mouscher's father died of glioblastoma multiforme, an aggressive brain cancer, in 1993. Also, in the same article, gynecological oncologist Ivor Benjamin's position at the University of Pennsylvania was incorrectly given. He is an assistant professor in the department of radiation oncology at the university.
