Did NY dentist dump unconscious patient on sidewalk?

In New York, a 71-year-old woman reportedly passed out during a dentist's appointment, and the dentist is accused of ... well, just dumping her on the sidewalk. It might have started as an allergic reaction, but she suffered severe brain damage and might not live. The dentist's attorney says he didn't have anything to do with it.
