Trichloroethylene health risk assessment: a new and improved process.

Trichloroethylene (TCE), an environmental contaminant of National concern, is the focus of a new health risk assessment process incorporating the Proposed Cancer Risk Assessment Guidelines. This paper describes not only how TCE became an environmental problem for the Air Force, but also details the new Risk Assessment process envisioned by the Environmental Protection Agency's (EPA) National Center for Environmental Assessment (NCEA). Insights on epidemiological evaluations, both past and future, and their impact on the cancer classification of TCE are discussed.

Travelers' diarrhea among United States military personnel during joint American-Egyptian armed forces exercises in Cairo, Egypt.

A study was conducted of travelers' diarrhea in a United States military population on deployment in Cairo, Egypt, during July and August 1987. Acute diarrhea requiring medical attention developed in 183 (4%) of 4,500 troops. A possible etiologic agent was identified in 49% of all diarrhea cases.

Immunologic responsiveness and safety associated with the Coccidioides immitis spherule vaccine in volunteers of white, black, and Filipino ancestry.

A trial of the killed Coccidioides immitis spherule vaccine was undertaken with 151 healthy skin test negative adult volunteers and controls to evaluate the safety of selected regimens, the induction of humoral and cell-mediated immune responses, and to determine if there were immunogenetic differences in these responses. The vaccine was given as three intra-deltoid doses over 8 weeks. No severe systemic symptoms were noted, although 3% of 3.

Anaplastic seminoma: an analysis of 77 patients.

Over a 28 year period, 77 patients with early stage anaplastic seminoma of the testis were treated by orchiectomy and lymphatic irradiation at three Army medical centers. With a median follow-up of 97 months, the 10 year actuarial survival is 96% of Stage I patients and 87% for Stage II patients. For patients with Stage I anaplastic seminoma no survival advantage can be demonstrated for adding mediastinal and supraclavicular irradiation versus para-aortic and pelvic irradiation alone.
