BACKGROUND The British Thoracic Society (BTS) Standards of Care (SoC) Committee produced a standard of care for occupational asthma (OA) in 2008, based on a systematic evidence review performed in 2004 by the British Occupational Health Research Foundation (BOHRF). METHODS BOHRF updated the evidence base from 2004-2009 in 2010. RESULTS This article summarises the changes in evidence and is ...
Occupational allergies are generally regarded as diseases resulting from a hypersensitivity (exaggerated response) of the immune system to substances encountered in the work environment. Bakers’ asthma, like other forms of occupational asthma, is probably the most serious manifestation of occupational allergy among bakery workers. It is caused by immunological sensitisation and subsequent aller...
Occupational asthma due to the pyrolysis products of polyvinyl chloride (PVC) produced by shrink wrapping processes has previously been reported. The first case of occupational asthma in a shrink wrap worker using a different plastic, polyethylene, is reported; the association was confirmed by specific bronchial provocation testing.
sthma and other idiosyncratic respiratory diseases have become an increasingly important component of the occupational lung disease burden in the United States and other developed countries as more cases are recognized and the pneumoconioses come under control (see Mao, “Cornpensation for Occupational Asthma in Quebec, “ this issue). Unfortunately, control of occupational asthma cannot be achie...
Much has been learned from epidemiologic studies conducted in the past 4 decades that can be directly applied to the management of workers affected with occupational asthma. Studies have provided information about host factors, environmental exposure, and occupational agents posing the highest risks for development of severe irreversible airway obstruction and asthma disability. Investigators h...
Background Baker’s asthma is one of the most common types of occupational asthma and its prevalence is increasing in the last years. Diagnosis of occupational asthma is complex. The poor specificity of current diagnostic approaches may be associated with insufficient purity of wheat extracts or lack of inclusion of major allergens in them. In this work, we use microarray technology to character...
W ork-related asthma, which includes occupational asthma as well as work-aggravated asthma, has become one of the most prevalent occupational lung diseases. In spite of increasing knowledge of the causes and underlying pathophysiological mechanisms, this preventable disorder continues to account for at least 15% of all asthma cases in the adult population and is responsible for a significant so...
Immediate hypersensitivity reactions ranging from mild urticaria to life threatening anaphylaxis after exposure to natural rubber latex have been reported frequently in health care workers while occupational asthma due to latex exposure is less well studied. The results of specific challenge tests and immunological tests in four health care workers with work related respiratory and skin disorde...
PURPOSE OF REVIEW Diisocyanates are the leading cause of occupational asthma, the most commonly reported lung disease associated with the workplace. Clinical studies have implicated the immune system in the pathogenesis of occupational asthma, but ethical and moral issues prevent mechanistic investigations in humans. For this reason, the development and characterization of animal models are ger...
The contribution of workplace exposures to the prevalence of asthma in adults has been minimized in the epidemiology of this illness. Analysis of the 1978 Social Security Disability Survey provides a population-based assessment as a novel approach utilizing self-attributed, occupationally related asthma as a measure of disease. Of 6,063 respondents, 468 (7.7 percent) identified asthma as a pers...
