DA: Doc Masturbated on Patient, Sexually Assaulted 3 Others He wrote a book on doctor-patient relations By Michael Harthorne, Newser Staff Posted Mar 24, 2016 6:40 PM CDT 60 comments Comments (Shutterstock) (Newser) – A prominent former New York City emergency room doctor already charged with sexually assaulting two women in his care has been indicted on additional charges of sex abuse for assaulting two more women he treated, the AP reports. David Newman, who wrote a book on the patient-doctor relationship and claims to have served in a combat hospital in Iraq, victimized the women at Mount Sinai Hospital between August and January, according to court papers. In one case, Newman injected a woman with pain killers and then masturbated on her, the papers charge. The Manhattan DA called the woman's abuse while under sedation by a doctor a patient's "nightmare scenario." Newman has pleaded not guilty to all of the counts. Newman was arrested after the first woman claimed he masturbated on her and a semen sample from her face matched Newman's DNA. (An "embarrassed" Newman claims he masturbated prior to treating the woman and may have had ejaculate on his hands.) Following his arrest, the other women, whose ages ranged from 18 to 29, came forward alleging they were similarly abused, authorities said. Newman is the author of Hippocrates' Shadow: Secrets From the House of Medicine, a book that examines "the fraying of patient-doctor relations" and advocates a "new paradigm to rebuild the bridge between physicians and their patients."
