Clinical evaluation, management, and prevention of work-related asthma.

Work-related asthma (WRA) is asthma that is attributable to, or is made worse by, environmental exposures in the workplace. WRA has become the most prevalent occupational lung disease in developed countries, is more common than is generally recognized, and can be severe and disabling. Identification of workplace exposures causing and/or aggravating the asthma, and appropriate control or cessation of these exposures can often lead to reduction or even complete elimination of symptoms and disability. This depends on timely recognition and diagnosis of WRA. In this review, the diagnostic evaluation has been organized in a stepwise fashion to make it more practical for primary care physicians as well as physicians specializing in occupational diseases and asthma. WRA merits more widespread attention among clinicians, labor and management health and safety specialists, researchers, health care organizations, public health policy makers, industrial hygienists, and others interested in disease prevention.

Frequency dependence of compliance in the evaluation of patients with unexplained respiratory symptoms.

Frequency dependence of compliance (FDC) reflects non-homogeneous ventilatory distribution and, in the presence of a normal measured airway resistance, suggests peripheral airways dysfunction. This study evaluated peripheral airway function and bronchial reactivity in irritant exposed or non-exposed individuals with normal routine pulmonary function tests (PFTs) who had persistent unexplained lower respiratory symptoms. Twenty-two patients were identified with persistent respiratory symptoms and with normal chest X-ray and PFTs. Twenty were non-smokers; two had stopped smoking more than 10 years before evaluation. Twelve patients had been exposed to irritants in their workplaces or at home. Non-specific bronchial hyper-reactivity (nsBHR) and FDC, pre- and post-bronchodilator, were measured in all patients. Studies were repeated in 6/12 irritant-exposed subjects after exposure removal and inhaled corticosteroid treatment. Whereas 12/22 patients had nsBHR, all 22 subjects demonstrated FDC [dynamic lung compliance/static lung compliance Cdyn,1 / Cst,1 at respiratory frequency 60 min(-1) (f60), mean 46%, range 27-67%]. After bronchodilator administration, a 15% improvement Cdyn,1 was observed most consistently at f60 (mean% improvement 26%, 95% CI 14-38%) and in subjects without nsBHR. However, Cdyn,1 at f60 did not return to normal after inhaled bronchodilator. Irritant-exposed and unexposed individuals appeared similar in results of testing for FDC and nsBHR. FDC and its response to bronchodilators provide objective physiological measures of an airway abnormality which may provide a basis for clinical symptoms in patients with normal routine pulmonary function studies. The presence of persistently abnormal FDC after bronchodilator (BD) and on follow up studies may reflect chronic inflammatory and/or structural changes in the airways in addition to bronchoconstriction.

Occupational and environmental medicine in New York State.

New York State (NYS) is home to 7.2% of the population and producer of 8.4% of the gross domestic product of the United States. The history and the current status of occupational and environmental medicine (OEM) research, educational resources, clinical practice patterns, and regulatory framework in NYS are reviewed. Changes anticipated or already taking place in health care financing, clinical practice patterns, occupational safety and health regulations and enforcement, and funding for research and medical education at the national level, are already having an impact in OEM activities in NYS.

Minority workers and communities.

Environmental and occupational hazards do not affect all communities equally. Members of ethnic and racial minorities, whether as working people or as community residents, sustain disproportionate risks from chemical, physical, and biological hazards. This paper reviews the nature of these disproportionate risks, focusing primarily on the workplace, but considering general environmental exposures as well. It discusses three principal mechanisms of increased risk: excessive hazardous exposures in both the workplace and the general environment, increased susceptibility, and inferior healthcare. It presents evidence that, as the result of these factors, members of minority groups display elevated rates of work-related illness, injury, fatality, and disability. Finally, it offers recommendations with regard to research, primary prevention, minority recruitment into the occupational health professions, and treatment and compensation for injured and ill minority workers.
