results the overall prevalence of occupational asthma was 9.7%. this rate was 13.8% in the exposed group. logistic regression analysis showed that even after adjustment for confounding factors, a significant correlation existed between the frequency of occupational asthma and exposure to the produced dust particles (p < 0.05). in addition, age, work experience, body mass index, cigarette smokin...

occupational asthma is defined as “a disease of variable airflow limitations and/or airway hyper-responsiveness due to causes and conditions attributable to a particular occupational environment and not stimuli that are being encountered outside the workplace.” an analysis of general population-based studies published up to 2007 showed that 17.6% of all adultonset asthma is due to workplace exp...

BACKGROUND The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. OBJECTIVE The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for incr...

background: asthma is a chronic multifactorial disease with a high prevalence. among asthma risk factors, the effect of baking in wood tenor ovens (traditional form of baking) on bronchial asthma is still debated. the aim of this study was to determine the association between baking in wood tenor ovens and incidence and control of bronchial asthma. materials and methods: this descriptive study ...

baker's asthma is one of the most common forms of occupational asthma. this study was conducted to determine prevalence of asthma and rhinitis among bakery workers in the city of sanandaj, the provincial center of kurdistan province in the west of iran in the in summer 2006. in this study 776 bread bakery workers were included. these subjects were selected randomly among 1620 bakery workers. th...

occupational asthma has been reported  to  be the most  common  chronic respiratory occupational disease in many developed countries, and  as with other  occupational lung diseases, occupational asthma is potentially preventable. we report  the case of a 24-year-old baker who experienced pneumomediastinum as a consequence of workplace exposure. this is the first report of pneumomediastinum as a...

background :asthma is the most common respiratory disease with an increasing prevalence. on the other hand, obesity is also a challenging disease compromising health in human communities. this study sought to assess the correlation of asthma and body mass index (bmi) in occupational setting.   methods : this study was conducted in a cable manufacturing company in 2012. a total of 551 workers fr...

BACKGROUND Primary prevention of occupational asthma requires timely identification and regulation of asthma-causing agents. METHODS We examined 39 substances identified as causing allergic occupational asthma in the US to determine the basis for their identification and their regulatory status. We compared them with occupational asthmagens identified and regulated in the UK and Germany. RE...

With the accelerating pace of new knowledge about occupational asthma, systematic epidemiological approaches have yielded important new insights into its clinical characteristics. Such questions as "what proportion of all cases of asthma are caused by occupational exposures?" and "is occupational asthma incidence rising?" can now be answered. Surveillance programmes estimate the number of expos...

BACKGROUND The pathogenesis and the pathologic alterations of occupational asthma are similar to those of nonoccupational asthma. Occupational asthma may therefore represent a useful model of "human asthma" to investigate mechanisms and pathophysiology of asthma in general. In an occupational setting the cause and onset of asthma may be easily identified, and the natural history may be examined...
