If the Japanese were guilty of running germ warfare tests elsewhere on American POWs, they were guilty of conducting surgical experiments at Itchioka. "Burning Feet," as my father had learned, was treated simply by improving the diet. But one patient suffering from it was forced by a Japanese doctor to submit to an abdominal sympathectomy, a complicated and dangerous operation. As my father wrote in his notes at the time:
The value of these operations for this condition was highly questionable even on theoretical grounds. In effect, Lt. Nisura (the Japanese surgeon) was using these patients as guinea pigs. The operation on____, without consent, and over the objection of Dr. Jackson (the attending physician), which resulted directly in___'s death, constitutes even in its most favorable light—manslaughter.
