“A prominent UC Davis neurosurgeon was banned from performing medical research on humans after he and an underling were accused of experimenting on dying brain cancer patients without university permission, The Bee has learned.

Documents show the surgeons got the consent of three terminally ill patients with malignant brain tumors to introduce bacteria into their open head wounds, under the theory that postoperative infections might prolong their lives. Two of the patients developed sepsis and died, the university later determined.

The actions – described by two prominent bioethicists as “astonishing,” and a “major penalty” for the school – threaten both the doctors’ professional careers and the university’s reputation and federal-funding status.”
