Kansas City, Kan. ? A Kansas doctor has been sentenced to time served after pleading guilty to being part of a scheme to sell a phony system to diagnose and cure Lyme disease.

U.S. Attorney Barry Grissom said Wednesday that 61-year-old John Toth of Topeka was also sentenced to two years supervised released and fined $25,100.

Toth has already served 26 months in prison after pleading no contest to state manslaughter charges in 2007 after the death of a patient. He was released in 2010.

In the federal case, Toth admitted in October that he and three co-defendants began selling a microscope they said could diagnose Lyme disease. They also promoted a drug treatment plan they claimed could cure the disease.
