With second med school dean out, what's up with USC?

USC announced Thursday that Dr. Rohit Varma is no longer dean of its Keck School of Medicine. He was accused of sexually harassing a young female med school fellow. Varma succeeded Dr. Carmen Puliafito, who resigned last year. The LA Times reported that Puliafito used illegal drugs and partied with criminals and prostitutes -- one of whom overdosed in his hotel room.
