Sabia virus incident at Yale University.

An incident involving a human exposure to a newly isolated arenavirus, Sabia virus, in the Yale Arbovirus Research Unit occurred at Yale University on August 8, 1994. A senior-level visiting research scientist was exposed to Sabia virus while purifying the virus from a large volume of tissue culture fluid. The exposure resulted in development of a Sabia virus infection followed by recovery of the patient.

Radiation safety as part of a comprehensive university occupational health and safety program.

Rutgers University has developed an integrated occupational health and safety program incorporating the disciplines of radiation protection, chemical hygiene, industrial hygiene, occupational safety, hazardous substance disposal, and environmental control. The program was implemented by the Department of Radiation and Environmental Health and Safety which was organized in a nontraditional way to provide an interdisciplinary resource and service to a large state university community. In the relatively short period of time that the new organization functioned at full capacity, the strengths of the new organization as well as a few weaknesses have become apparent.

The nature of the background in radionuclide ventriculography: deductions from the mathematical behaviour of the ejection fraction.

The relationship between the ejection fractions calculated from 'uncorrected' radionuclide time activity curves (UEF) and angiographic ejection fractions (AEF) in 200 catheterized patients yielded the regression equation AEF = 1.74 UEF + 0.21.

Differentiation of Charcot joint from osteomyelitis through dynamic bone imaging.

The bone scans of 25 patients with a clinical diagnosis of diabetic osteoarthropathy (Charcot joint) of the ankle and foot were analysed using the technique of dynamic bone imaging. The analysis of time-activity curves generated over the Charcot joint, the contralateral joint and the bone above the Charcot joint, produces characteristic patterns that are distinguishable from the ones observed for osteomyelitis. Recently it has been shown that the significance of dynamic bone imaging resides in its correlation to physiological and morphological components of bone.
