Allergic and immunologic profile of symptomatic Persian Gulf War veterans.

Background: Persian Gulf War veterans have been enrolled in the Veterans Administration Persian Gulf Health Registry for evaluation of unexplained symptoms and illnesses. The allergy and immunology division at the West Los Angeles Veterans Administration Medical Center evaluated 20 consecutive symptomatic Persian Gulf War veterans.

Objective: The purpose of this study was to examine the immunologic profiles of symptomatic Persian Gulf War Veterans.

Severe hypersensitivity reaction during hemodialysis.

Background: Hemodialysis-associated hypersensitivity reactions are well documented in the literature. Ethylene oxide sensitization and activation of complement are important factors involved during such reactions. The majority of severe hypersensitivity reactions in dialysis patients, however, is due to sensitization to ethylene oxide.

Performance of dust respirators with facial seal leaks: I. Experimental.

The ability of representative half-mask and single-use respirators with facial seal leaks to provide protection against aerosols was evaluated by experimental measurement. Respirators were mounted on a manikin in a test chamber and operated at seven steady flow rates over the range of 2 to 150 L/min. Samples of polydisperse and monodisperse aerosols were taken from inside and outside the respirator and analyzed by a calibrated optical particle counter over the particle-size range 0.

Acute symptoms secondary to formaldehyde exposure in a pathology resident.

Formaldehyde is ubiquitous and found at work and at home. The National Institute of Occupational Safety and Health (NIOSH) lists fifty-two occupations with substantial formaldehyde exposure. Pathology is one such occupation.
