A gathering body of evidence has repeatedly revealed associations between indoor fungi and initiation, promotion, and exacerbation of allergic respiratory disease. The relationship between the exposure and outcome are complicated by the difficulties in measuring both exposure and outcome, the multifactorial nature of the disease, and the wide range of potential confounders. New technologies are...

The authors investigated changes in respiratory health after September 11, 2001 ("9/11") among residents of the area near the World Trade Center (WTC) site in New York City as compared with residents of a control area. In 2002, self-administered questionnaires requesting information on the presence and persistence of respiratory symptoms, unplanned medical visits, and medication use were sent t...

OBJECTIVE The objective of this study was to assess respiratory outcomes and environmental exposure levels of workers in cage-housed and floor-housed poultry operations. METHODS Poultry operations were evaluated for total dust, endotoxin, and ammonia, and respiratory symptoms and lung function tests of workers were conducted. RESULTS Workers in floor-housed poultry operations had significan...

BACKGROUND Non-protective work practices followed by farm workers during spraying of pesticides lead to occupational exposure among them. OBJECTIVE This study is designed to explore the respiratory health and hematological profile of agricultural workers occupationally exposed to OP pesticides. MATERIALS AND METHODS A cross sectional study was undertaken among 166 pesticide sprayers working...

INTRODUCTION Occupational exposure to grain dust causes respiratory symptoms and pathologies. To decrease these effects, major changes have occurred in the grain processing industry in the last twenty years. However, there are no data on the effects of these changes on workers' respiratory health. OBJECTIVES The aim of this study was to evaluate the respiratory health of grain workers and far...

Background and Purpose: Inhalation of hardwood dust may produce a range of adverse health effects in the upper and lower respiratory system, including asthma, along with Sino-nasal cancer and nasopharyngeal cancer. This study was carried out to evaluate personal exposure to wood dust among workers in chipboard and furniture production saloons in Neka Choob factory, Iran. Materials a...

The association between occupational exposure to airway irritants and the prevalence of chronic respiratory symptoms and level of lung function, and whether these associations were modified by airway hyperresponsiveness, smoking, and a history of allergy were studied in 668 workers from synthetic fibre plants. Respiratory symptoms were recorded with a self administered Dutch version of the Brit...

BACKGROUND Previous studies have suggested associations of adult exposures to secondhand smoke (SHS) with respiratory symptoms, but no study has focused on blue-collar industrial environments. We assessed the association between SHS and respiratory symptoms in 1,562 non-current smoking U.S. trucking industry workers. METHODS Information on SHS exposure and respiratory health was obtained by q...

Acute exposure to high doses of toluene can generate respiratory depression. However, neurotoxic mechanism of its action in the brainstem is not completely clear. In this work, acute, but not subchronic, exposure of rats to toluene increased leu-enkephalin immunostaining in several myelencephalic nuclei implicated in cardiorespiratory control. Due to the physiological role of enkephalins in the...
