    ABSTRACT: Background Currently, little data is available about the management of asthma in the working population. The aim of this study was to describe asthma control and severity among workers according to current or previous allergic rhinitis comorbidity. Methods A network of occupational physicians participated in this pilot study on a voluntary basis. They included a random sample of salaried workers during their systematic occupational medical check-up. All subjects completed a self-administered questionnaire based on the European Community Respiratory Health Survey screening questionnaire, and if they reported any respiratory symptoms including allergic rhinitis, the physician filled in a medical questionnaire. Current asthma control and severity were evaluated according to 2006 Global Initiative for Asthma guidelines. Results A total of 110 occupational physicians from two French regions participated. Out of the 6906 employees screened, 3102 identified respiratory symptoms and completed the medical questionnaire and performed spirometry. Overall, 374 were identified as current asthmatics, including 271 (72.5 %) with allergic rhinitis. Among current asthmatics with current allergic rhinitis (n = 95), 68.8 % had partially controlled asthma or uncontrolled asthma, including 51.6 % who received insufficient anti-asthmatic treatment. Partly or no control asthma was not associated with current rhinitis (OR = 1.4; 95 % CI: 0.8-2.7). Current asthmatics with current or previous allergic rhinitis had a significantly lower risk of emergency department visits than current asthmatics without allergic rhinitis (respectively 11.6, 17.1 and 29.1 %; P = 0.002). Conclusions Most current asthmatics both with and without allergic rhinitis had uncontrolled asthma, with inappropriate treatment. Future intervention strategies need to be developed for effective control and prevention of asthma in the workplace.

    ABSTRACT: The aim of the present study was to analyse the interaction between asthma and smoking in the risk of adult airway obstruction, accounting for atopy. In the European Community Respiratory Health Survey, 15 668 persons aged 20-56 years underwent spirometry in 1991-1993 and 9 years later (n = 8916). Risk of airway obstruction and lung function decline associated with smoking and early-onset (<10 years of age) and late-onset (>10 years of age) asthma were analysed with generalised estimating equation models and random-effect linear models, adjusting for covariates. Interaction of asthma with smoking was expressed as relative excess risk due to interaction (RERI). A 20-fold increase in adult airway obstruction was found among those with early-onset asthma independently of smoking status (never smokers: OR 21.0, 95% CI 12.7-35; current smokers: OR 23.7, 95% CI 13.9-40.6). Late-onset asthma was associated with airway obstruction, with a stronger association among current smokers (OR 25.6, 95% CI 15.6-41.9) than among never-smokers (OR 11.2, 95% CI 6.8-18.6) (RERI 12.02, 95% CI 1.96-22.07). Stratifying by atopy, the association between smoking and asthma was most pronounced among nonatopics. Early- and late-onset asthma were associated with 10-20-fold increased risk of adult airway obstruction. Smoking increased the risk of adult airway obstruction in subjects with asthma onset after age 10 years. Investigation of measures potentially preventive of chronic obstructive pulmonary disease development following asthma is urgently needed. ©ERS.

    ABSTRACT: Background Tobacco control measurements’ had little impact on smoking prevalence in Morocco. The aim of this study is to provide first data on smoking attributable mortality in Morocco. Method The Smoking-Attributable Mortality, Morbidity and Economic Costs (SAMMEC) software was used to estimate the smoking attributable mortality (SAM) in Casablanca region in 2012. Smoking prevalence and mortality data of people aged 35 years or older were obtained from the national survey on tobacco “Marta” and from Health Ministry Mortality System, respectively. Results Of the 5261deaths of persons aged 35 years and older, 508 (9.7%) were attributable to cigarette smoking. This total represents 16.2% of all male deaths (n =448) and 2.0% (n =80) of all female deaths in this region. The leading four causes of smoking attributable deaths were lung cancer (177), chronic airways obstruction (76), ischemic heart disease (39), and cerebrovascular disease (31). Conclusion Tobacco use caused one out of six deaths in Casablanca in 2012. Four leading causes (lung cancer, ischemic heart disease, cerebrovascular disease and chronic airways obstruction,) accounted for 51.6% of SAM. Effective and comprehensive actions must be taken in order to slow this epidemic in Morocco.

    ABSTRACT: Background One of the most important measures for ascertaining the impact of tobacco is the estimation of the mortality attributable to its use. Several indirect methods of quantification are available. The objective of the article is to assess methodologies published and applied in calculating mortality attributable to smoking. Methods A review of the literature was made for the period 1998 to 2005, in the electronic databases MEDLINE. Twelve articles were selected for analysis. Results The most widely used methods were the prevalence methods, followed by smoking impact ration method. Ezzati and Lopez showed that the general rate of Smoking attributable mortality (SAM) globally was 12% (18% in men). Across countries, attributable fractions of total adult deaths ranged from 8% in Southern Africa, 13.6% in Brazil (18.1% in men) and 25% in Hong Kong (33% in men). Conclusion The variations can be attributed to methodological differences and to different estimates of the main tobacco-related illnesses and tobacco prevalence. All methods show limitations of one type or another, yet there is no consensus as to which furnishes the best information.

    ABSTRACT: Lung cancer is the leading cause of cancer morbidity and mortality. Its management has a significant economic impact on society. Despite a high incidence of cancer, so far, there is no national register for this disease in Morocco. The main goal of this report was to estimate the medical costs of lung cancer in our country. We first estimated the number of annual new cases according to stage of the disease on the basis of the Grand-Casablanca-Region Cancer Registry data. For each sub-group, the protocol of treatment was described taking into account the international guidelines, and an evaluation of individual costs during the first year following diagnosis was made. Extrapolation of the results to the whole country was used to calculate the total annual cost of treatments for lung cancer in Morocco. Overall approximately 3,500 new cases of lung cancer occur each year in the country. Stages I and II account for only 4% of cases, while 96% are diagnosed at locally advanced or metastatic stages III and IV. The total medical cost of lung cancer in Morocco is estimated to be around USD 12 million. This cost represents approximately 1% of the global budget of the Health Department. According to AROME Guidelines, about 86% of the newly diagnosed lung cancer cases needed palliative treatment while 14% required curative intent therapy. The total cost of early and advanced stages lung cancer management during the first year were estimated to be 4,600 and 3,420 USD, respectively. This study provides health decision-makers with a first estimate of costs and the opportunity to achieve the optimal use of available data to estimate the needs of health facilities in Morocco. A substantial proportion of the burden of lung cancer could be prevented through the application of existing cancer control knowledge and by implementing tobacco control programs.

    ABSTRACT: The aim of the present study was to examine the influence of childhood respiratory infections on adult respiratory health. In 1992-1994, the European Community Respiratory Health Survey recruited community based samples of 20-44-yr-old people from 48 centres in 22 countries. Study participants completed questionnaires and underwent lung function testing. On average, 8.9 yrs later, 29 centres re-investigated their samples using similar methods. Mixed effects models comprising an estimate for the random variation between centres were used to evaluate the relevant associations. In total, 9,175 patients participated in both studies, of whom 10.9% reported serious respiratory infections (SRI) before 5 yrs of age and 2.8% reported hospitalisation for lung disease (HLD) before 2 yrs if age. SRI was associated with current wheeze (odds ratio (OR) 1.9, 95% confidence interval (CI) 1.7-2.2), asthma (OR 2.5, 95% CI 2.2-3.1), and lower forced expiratory volume in one second (FEV(1); 89 mL; 95% CI 54-126), forced vital capacity (FVC; 49 mL; 95% CI 8-90) and FEV(1)/FVC ratio (-1.2%; 95% CI -1.8- -0.6). Childhood respiratory infections were also associated with new asthma (OR 1.5, 95% CI 1.03-2.0), new wheeze (OR 1.5, 95% CI 1.0-2.4) and persistent wheeze (OR 2.2, 95% CI 1.4-3.6) but not with a decline in lung function. Similar findings were observed for HDL. These associations were significantly consistent across centres. SRI was associated with lower FEV(1) when excluding ever asthmatics and current wheezers. The impact of early infections was significantly larger in subjects exposed to maternal or active smoking. The impact of childhood respiratory infections on the respiratory system may not only last into adulthood but also influence development and persistence of adult respiratory morbidity.
