Hypersensitivity pneumonitis (HP) develops after inhalation of many different environmental antigens, causing variable clinical symptoms that often make diagnosis uncertain. The prevalence of HP is higher than recognized, especially its chronic form. Mechanisms of disease are still incompletely known. Strategies to improve detection and diagnosis are(More)
Hypersensitivity pneumonitis (HP) was identified among employees in an automobile parts manufacturing facility. Mycobacteria immunogenum (MI) was identified as a metal removal fluid (MRF) contaminant at this facility and had been identified as a contaminant in other facilities where HP had occurred. We therefore questioned whether measurement of MI-specific(More)
While there is a growing body of information about hazards of nanomaterials, little is known about the risks to workers exposed to them. However, workers are the first people in society that are being exposed to the growing inventory of "nano-enabled" products in commerce. The number of workers involved in the investigation, manufacture, production, and(More)
Extensive water damage after major hurricanes and floods increases the likelihood of mold contamination in buildings. This report provides information on how to limit exposure to mold and how to identify and prevent mold-related health effects. Where uncertainties in scientific knowledge exist, practical applications designed to be protective of a person's(More)
OBJECTIVE This article provides an overview of the issues that arise with medical surveillance, exposure registration, and epidemiologic research involving nanomaterial workers. METHODS An occupational health perspective is applied to detecting risks in nanomaterial workers individually and as a group. RESULTS General principles for medical(More)
OBJECTIVE Health authorities, employers, and worker representatives are increasingly faced with making decisions about occupational health surveillance of workers potentially exposed to engineered nanoparticles. This article was developed to identify options that can be considered. METHODS The published scientific literature on health effects from(More)
The extent of health effects and exposure to environmental contaminants among workers and residents indirectly affected by the September 11, 2001, attack on the World Trade Center (WTC) is unknown. The objective of this study was to evaluate concerns related to health effects and occupational exposures three months after the WTC disaster among a population(More)
The goal of occupational health practice is to protect the health of workers by preventing diseases and injuries from occurring. When work activities are anticipated, recognized, or found during an investigation to involve risks to workers’ health, preventive measures should be taken to control hazardous exposures in the workplace. Respirators are often(More)
There has been increased concern over health effects related to potential exposure of building occupants to bioaerosols. We report the case of a worker with a respiratory illness related to bioaerosol exposure in a water-damaged building with extensive fungal contamination. We performed environmental tests to evaluate potential exposure to fungi, and we(More)
