10 Background: The influence of occupation and ex/passive smoking on inflammatory phenotype is not well 11 understood. The aim of this study was to examine the relationship between occupation, past smoking and current 12 passive smoking and airway inflammation in a population of adults with refractory asthma. 13 Methods: Sixty-six participants with refractory asthma were characterised. Occupati...
This consensus statement provides practical recommendations for specific inhalation challenge (SIC) in the diagnosis of occupational asthma. They are derived from a systematic literature search, a census of active European centres, a Delphi conference and expert consensus. This article details each step of a SIC, including safety requirements, techniques for delivering agents, and methods for a...
Occupational asthma accounts for about 15% of adult-onset [1] and is associated with poorer quality life than in workers similar severity not caused by exposures at work, main...
Previously we observed an excess risk for occupational asthma among florists with rhinitis. To further evaluate the link between upper and lower airways, we investigated united airways disease in the same occupational group. Occupational history, symptoms and atopy were investigated among 128 florists. Age-, smoking-, and gender-adjusted risks were calculated using logistic regression models co...
T here has been a remarkable increase in recent years of individual and public perceptions about health effects caused i y toxic chemical and physical agents in the workplace and elsewhere in the environment. Although the full nature and extent of the health burden resulting from occupational and environmental exposures remain to be elucidated, a consensus has emerged that our health care syste...
We have previously designed a system for exposure to particles and described the preliminary results in 20 subjects exposed to occupational sensitizers in powder form (Cloutier Y, et al. - Eur Respir J, 1989; 2: 769). Modifications have been made to the particles generator, exposure chamber and sampling ports. Furthermore, in order to improve the stability of concentrations in the exposure cham...
BACKGROUND This study describes exposure levels of bakery and pastry apprentices to flour dust, a known risk factor of occupational asthma. METHODS Questionnaires on work activity were completed by 286 students. Among them, 34 performed a series of two personal exposure measurements using a PM2.5 and PM10 personal sampler during a complete work shift, one during a cold ("winter") period, and ...
BACKGROUND Acute asthma attacks strike unpredictably and may lead to hospitalization in otherwise healthy individuals. The burden of asthma hospitalization on the US health care system has greatly interested health care workers, many of whom see the incidence of asthma as increasing. OBJECTIVES To examine the annual incidence of hospitalization and the frequency of subsequent hospitalization ...
AIMS To summarise incidence rates and epidemiological characteristics of new cases of work related respiratory disease reported by specialist physicians in thoracic and occupational medicine, with particular reference to occupation, industry, and causal agents for asthma, inhalation accidents, and allergic alveolitis. METHODS Cases reported 1992-2001 to the SWORD and OPRA national surveillanc...
