BONITA SPRINGS, Fla.- A controversial Bonita Springs doctor, accused of using questionable stem cell procedures, will lose his license.

Late this afternoon, a judge ruled the Department of Health proved malpractice by Bonita Springs Dr. Zannos Grekos. Grekos was on trial back in October of last year for using a controversial stem cell procedure in which a woman died back in 2010. Another male patient died in 2012. The Department of Health says Grekos injected bone marrow into the female patient's brain, and didn't inform the woman of the grave risk.

Today, the judge issued the ruling. Now, it's been recommended that the Board of Medicine revoke Grekos' license and fine him $20,000.
