of osteopathic medical schools use the Osteopathic Oath in place of or in addition to the Hippocratic Oath. The Osteopathic Oath was first used in 1938, and the current version has been in use since 1954. One of the most significant revisions was first drafted in 1948 by the World Medical Association (WMA), called the Declaration of Geneva. "During the post World War II and immediately after its foundation, the WMA showed concern over the state of medical ethics in general and over the world. The WMA took up the responsibility for setting ethical guidelines for the world's physicians. It noted that in those years the custom of medical schools to administer an oath to its doctors upon graduation or receiving a license to practice medicine had fallen into disuse or become a mere formality". In Nazi Germany, medical students did not take the Hippocratic Oath, although they knew the ethic of "nil nocere"—do no harm. In the 1960s, the Hippocratic Oath was changed to require "utmost respect for human life from its beginning", making it a more secular obligation, not to be taken in the presence of any gods, but before only other people. When the oath was rewritten in 1964 by Louis Lasagna, Academic Dean of the School of Medicine at Tufts University, the prayer was omitted, and that version has been widely accepted and is still in use today by many US medical schools: I swear to fulfill, to the best of my ability and judgment, this covenant: I will respect the hard-won scientific gains of those physicians in whose steps I walk, and gladly share such knowledge as is mine with those who are to follow. I will apply, for the benefit of the sick, all measures [that] are required, avoiding those twin traps of overtreatment and therapeutic nihilism. I will remember that there is art to medicine as well as science, and that warmth, sympathy, and understanding may outweigh the surgeon's knife or the chemist's drug. I will not be ashamed to say "I know not", nor will I fail to call in my colleagues when the skills of another are needed for a patient's recovery. I will respect the privacy of my patients, for their problems are not disclosed to me that the world may know. Most especially must I tread with care in matters of life and death. If it is given me
