Ba'ltmasor Syndrome was a disease suffered by some Klingons. Typically, Ba'ltmasor Syndrome required the sufferer to take regular injections, at least once a week.
In 2367, J'Dan suffered from this disease. He used it as a cover in an attempt to steal Federation secrets. (TNG episode: "The Drumhead")
