Eligibility for low-dose computerized tomography screening among asbestos-exposed individuals
Objectives: The study aimed to incorporate an estimate of risk for asbestos exposure in the Canadian Cancer Risk Management Lung Cancer (CRMM-LC) microsimulation model. Methods: In CRMM-LC, a 3-year probability of developing lung cancer can be derived from different risk profiles. An asbestos-exposed cohort was simulated and different scenarios of low-dose computerized tomography (LDCT) screening were simulated. Results: As annual LDCT screening among non-asbestos-exposed individuals is less cost-effective than biennial screening, all the scenarios modeled for an asbestos-exposed cohort were biennial...
L’absence d’éosinophilie bronchique est-elle un facteur de mauvais pronostic de l’asthme professionnel?
L'asthme est une maladie inflammatoire des bronches qui se traduit par une respiration sifflante, de la toux et de la difficulté à respirer. Ces symptômes s'accompagnent de changements de la fonction respiratoire qui comprennent une obstruction des bronches ainsi qu'une irritabilité anormale de celles-ci. L'inflammation présente dans l'asthme correspond la plupart du temps à la présence de cellules appelées éosinophiles. L'asthme professionnel (AP) est un asthme qui est causé par une allergie à un...
How Does an Occupational Neurologist Assess Welders and Steelworkers for a Manganese-Induced Movement Disorder?
Part II, will present a synopsis of the evaluation including blood and urine manganese and results from one magnetic resonance image and discuss and analyze the results. Limitations and conclusions will be presented. Part I, from an earlier JOEM issue, focused on the historical background and literature supporting parkinsonism and manganese exposure, both from mining and welding. Differential diagnosis, including radiological assessment and methods were discussed.

Practice recommendations in the diagnosis, management and prevention of carbon monoxide poisoning
Carbon monoxide (CO) poisoning is common in modern society, resulting in significant morbidity and mortality in the United States annually. Over the past two decades, sufficient information has been published about carbon monoxide poisoning in the medical literature to draw firm conclusions about many aspects of the pathophysiology, diagnosis and clinical management of the syndrome, along with evidence-based recommendations for optimal clinical practice. This article provides clinical practice guidance to the pulmonary and critical care community with regard to the diagnosis, management and prevention...
Occupational eosinophilic cough conditions
This project was to improve understanding of emerging occupational respiratory conditions typified by chronic cough and airway eosinophilia. Chronic cough is associated with impaired quality of life and eosinophilic airway disorders may be associated with accelerated lung function decline. It is clear from the case reports that workplace allergens may induce cough-variant asthma and non-asthmatic eosinophilic bronchitis. These conditions may be more difficult to recognise as being occupational in nature given that by definition they lack some of the classical symptoms of asthma and the most common...
Allergie respiratoire professionnelle au cobalt
Le cobalt et ses composés ne sont que très rarement responsables de rhinite et/ou d'asthme professionnels. Dans les secteurs industriels exposant aux poussières de cobalt (principalement fabrication des métaux durs, usinage d'alliages spéciaux et de pièces en carbures métalliques frittés et polissage du diamant mais aussi utilisation de pigments dans l'industrie du verre et de la céramique et synthèse et conditionnement de sels de cobalt), c'est la conjonction d'un tableau clinique d'asthme et d'un...
Using Digital Chest Images to Monitor the Health of Coal Miners and Other Workers
Under the Federal Coal Mine Health and Safety Act of 1969, as amended by the Federal Mine Safety and Health Act of 1977, NIOSH administers a long-standing chest radiographic (x-ray) monitoring program for underground coal miners (The Coal Workers X-ray Surveillance Program [CWXSP]). Conventional screen-film chest radiographic imaging has been an indispensable tool for monitoring the lung health of miners and other dust-exposed workers. In these surveillance programs, trained readers assess a worker's chest radiograph for the presence and severity of occupational lung disease (parenchymal a...
