I seem to recall reading this in an issue of JAMA the AMA Journal of Medicine. THe backlash was absolutely extreme from some Jewish physicians believing that this was beyond the pale. Forget the fact, that Historical Medicine accounts have been written on the illnesses and deaths of many many other famous people from Mozart to Lincoln.
I believe you are referring to On the Physical Death of Jesus Christ (William D. Edwards, MD; Wesley J. Gabel, MDiv; Floyd E. Hosmer, MS, AMI) published in 1986.
