Summary of follow-up results from potential tuberculosis exposures
There were two isolated episodes of LeRC workers who were diagnosed with pulmonary tuberculosis (TB) during the fall of 1990. The specifics surrounding each case were very different, and it is clear that the two episodes were completely unrelated. The fact that the final diagnoses of pulmonary tuberculosis came within three weeks of each other was purely coincidental. The Occupational Medicine Service (OMS) conducted separate informational sessions and offered free PPD skin testing to all employees, both NASA and contractors, who felt that they were at risk of having been exposed to tuberculosis from either individual. The procedures and results of these are briefly discussed.

Screening for prostate cancer
Despite recent advances in both the survival and cure rates for many forms of cancer, unfortunately the same has not been true for prostate cancer. In fact, the age-adjusted death rate from prostate cancer has not significantly improved since 1949, and prostate cancer remains the most common cancer in American men, causing the second highest cancer mortality rate. Topics discussed include the following: serum testosterone levels; diagnosis; mortality statistics; prostate-sppecific antigen (PSA) tests; and the Occupational Medicine Services policy at LeRC.
