    ABSTRACT: Background: Many factors influence the return to work of workers with chronic low back pain (CLBP). They have been said to vary according to socio-professional group. This study first aimed to compare prognostic factors influencing the return to work of CLBP healthcare workers (HCWs) and other workers (non-HCWs) after rehabilitation coupled with an occupational intervention. The second objective was to improve the evolution of indicators such as clinical examination, psychosocial impact and pain impact. Methods: Between 2007 and 2012, a cohort of 217 CLBP workers (54.8 %-women; mean age = 41.3 ± 9.5 years, 118 non-HCWs; 99 HCWs mainly from the public sector) was included in an ambulatory rehabilitation program (standard physiotherapy or intensive network physiotherapy) coupled with an occupational intervention. Workers completed a questionnaire and had a clinical examination at baseline and after 24 months' follow up. Physical, social and occupational data was collected at the same time. Statistical analyses were performed to evaluate prognostic factors for return to work and compare the two worker populations. Results: There was no difference between groups for the rate of OP (occupational physician) intervention or type of physiotherapy. 77.3 % of workers returned to work after 2 years following inclusion. To be an HCW (OR 0.1; 95 % CI [0.03-0.34]), to have less than 112 sick- leave days (OR 1.00; 95 % CI [0.93-1.00]), a small fingertip-floor distance (OR 0.96; 95 % CI [0.93-0.99]), a low anxiety/depression score (OR 0.97; 95 % CI [0.95-1.00]), a low impact of CLBP on daily life (OR 0.96; 95 % CI [0.93-1.00]), and on quality of life (OR 0.98; 95 % CI [0.95-1.00]) at baseline were statistically associated with return to work after 2 years of follow up. Only the profession (workplace) was statistically associated with return to work after 2 years of follow up using multivariate analysis. Conclusion: To our knowledge, this is the first cohort study concerning predictive factors of RTW among CLBP workers after 2 years of follow up. Interventions in the work environment did not seem to predict job retention significantly. But only 50 % of the employees in both groups (HCW and non-HCW) had one intervention at their workplace after 2 years. This study underlined the fact that the type of physiotherapy with a well-trained physiotherapist used to take care of CLBP could not impact on the RTW forecast. To develop these initial results, it might be interesting to study the comparison between private and public sectors and to randomize the physiotherapeutic intervention.

    ABSTRACT: International studies on occupational risks in public hospitals are infrequent and only few researchers have focused on psychosocial stress in Moroccan Health Care Workers (HCWs). The aim of this study was to present and analyze Moroccan HCWs occupational risk perception. Across nine public hospitals from three Moroccan regions (northern, central and southern), a 49 item French questionnaire with 4 occupational risks subscales, was distributed to 4746 HCWs. This questionnaire was based on the Job Content Questionnaire. Psychosocial job demand, job decision latitude and social support scores analysis were used to isolate high strain jobs. Occupational risks and high strain perception correlation were analyzed by univariate and multivariate logistic regression. 2863 HCWs (60 %) answered the questionnaire (54 % women; mean age 40 years; mean work seniority 11 years; 24 % physicians; 45 % nurses). 44 % of Moroccan HCWs were at high strain. High strain was strongly associated with two occupational categories: midwives (2.33 OR; CI 1.41-3.85), full-time employment (1.65 OR; CI 1.24-2.19), hypnotics and sedatives use (1.41 OR; CI 1.11-1.79), analgesics use (1.37 OR; CI 1.13-1.66). Moroccan HCWs, physicians included, perceive their job as high strain. Moroccan HCWs use of hypnotics, sedatives and analgesics is high. Risk prevention plan implementation is highly recommended.

    ABSTRACT: The occupational skin diseases affecting mechanics appear to represent approximately 10% of the cases of occupational dermatitis. Irritation or allergic skin diseases are observed. Irritants factors are multiple and the major allergens are the preservatives in oils and greases but also in soaps. Metals (chromium and cobalt) and rubber are often encountered allergens. In the metal machining workers irritation dermatitis are observed in relation with caustic effect due to the presence of amines and preservatives in too high concentration. Allergies are related to the presence of metals, biocides, emulsifiers and deodorants or fragrances. Prevention is essential in these jobs.

    ABSTRACT: Nantes University Hospital comprises 20 activity sectors. To investigate the role of the work environment at the individual level, as well as the workplace level, in explaining the variability in employees' perception of stress. A self-administered enhanced Karasek Job Content Questionnaire was sent to employees. The main variables were the psychological job demand (PJD) score and the job decision latitude (JDL) score. Univariate and multivariate logistic regression analyses were conducted to estimate crude odds ratio (OR) and adjusted OR. One thousand eight hundred and sixty-eight workers were included. Nursing managers (25.9 ± 3.4), non-specialized nurses (25.6 ± 3.5) and physicians (25.3 ± 3.4) had the highest PJD. Cleaning staff (61.4 ± 11.4) and nurse aides (63.6 ± 8.8) had the lowest JDL. Items correlated with high PJD are: unacceptable work schedule, adjusted OR 2.16 (95% CI = 1.3-3.5); unsatisfactory workstation accessibility, OR 1.92 (95% CI = 1.1-3.2); getting from A to B, OR 1.67 (95% CI = 1.2-2.4); and heavy manual handling, OR 1.62 (95% CI = 1.1-2.3). Sleeping tablet use was linked to high PJD (P < 0.01), extra workload (P < 0.05) and tiredness (P < 0.05). Use of painkillers was correlated with musculoskeletal disorders (P < 0.05). Our study highlighted women >40 years old, nurse managers, physicians, permanent and/or full-time workers having a high PJD. Nursing aides, medical secretary and nurses presented with high strain. Better control measures should be implemented for those socioprofessional categories to improve prevention measures. This study should be repeated in the future with a multi-centre approach to determine the generalizability of the findings.

    ABSTRACT: Wood dust is a well-established risk factor for intestinal type sinonasal adenocarcinoma. The 5-year overall survival has varied from 20% to 80% according T1-T4 stages; 5-year survival according to histologic subtype has varied from 20% to 50%. To date, no study has evaluated whether environmental, occupational, and personal risk factors have any impact on both overall and cancer-specific survival. We aimed to determine whether exposure to carcinogenic risk factors besides wood exposure can influence the survival of patients with sinonasal ethmoid carcinoma. Retrospective cohort study of the association of survival data and occupational and personal carcinogenic risk factors. All patients hospitalized for ethmoid adenocarcinoma at the Nantes University Hospital between 1988 and 2004 were included . Data concerning TNM classification, histology, type and quality of tumor resection at the macro- and microscopic level, and occupational and personal exposure to carcinogens were collected. Statistical analysis was conducted using univariate and multivariate linear regression. A total of 98 patients were included with a response rate of 98%. Data showed 86% of patients had been exposed to wood dust. The 5-year survival was 62%. We first identified four factors that independently influenced overall survival: diplopia (P = .0159), spread to the orbit (P = .0113), bilateral involvement (P = .0134), TNM stage (P < .001). When the analysis included all occupational environmental factors (wood dust, solvent, and metals exposure) as well as personal risk factors, the length of exposure to metals (P = .0307) and tobacco exposure (P = .0031) also were found to influence 5-year overall survival. We identified high prevalence of colon cancer (4%) and double cancer (18%). We showed exposure to both environmental (tobacco) and occupational (metal dust) factors could influence survival in the diagnosis of a cancer. Our study suggests that screening for colon cancer should be offered to wood dust workers. A prospective multicentric study should be necessary to confirm our results.

    ABSTRACT: Contact dermatitis to cutting fluids is a very frequent cause of occupational skin disease, with different mechanisms for those caused by irritation or allergies. The different allergens in question are many and complex. Different batteries of patch tests are available but the interpretation of the relevance of positive tests is not simple. The aim of this work is to make clearer the investigative methods and the interpretation of the relevance of the results of patch tests, for more effective prevention.

    ABSTRACT: Occupational hands dermatoses are very frequent and disabling. Medical prevention is principally based on the application of individual skin protective measures. As a supplement to the protection by gloves, the application of a protective cream specifically adapted for manual labor has been studied to assess the efficacy, tolerance, cosmetic acceptability of the applied cream and the impact on the quality of life. Its daily use showed, that it was a individual response effective, well tolerated and adapted in subjects affected by an occupational irritant contact dermatitis with a significant improvement of quality of life.

    ABSTRACT: Inflammatory contact dermatitis is frequent in food industry workers (bakers, pastry cooks, butchers, porkbutchers and caterers, restaurants, slaughter-houses, etc.). It is due not only to foodstuff of plant origin (flour, fruits and vegetables) but also to foodstuff proteins of animal origin, as well as food additives, drinks and spices. The use of cleaning and sterilization products made more and more powerful to meet the demands of cleanliness and sterility in food stores is causing much occupational contact dermatitis, which simple preventive measures could avoid.

    ABSTRACT: Occupational medicine has always been part of social medicine, but focuses on the part of the population in paid employment. Investigations of occupational diseases have identified several toxic chemicals that can affect other sectors of society: examples include cancers due to sawdust, asbestos, benzene, as well as carcinogens, mutagens and reproductive toxins. Better knowledge of the risks posed by epoxy resins, cements, formaldehyde, lead, toluene and other chemical agents has helped to understand certain diseases in the population. Knowledge of musculoskeletal disorders due to repetitive work has been of help in other areas; gradual resumption of appropriate activity seems to be the best basic treatment. Studies of mental overload and its consequences in the workplace (suicide, depression, etc.) have implications for human relations in society as a whole. Multidisciplinary networking helps to regularly take stock of findings in occupational medicine that may be applicable to social medicine.

    ABSTRACT: Using French cut-offs for the Tuberculin Skin Test (TST), results of the TST were compared with the results of an Interferon-gamma Release Assay (IGRA) in Healthcare Workers (HCW) after contact to AFB-positive TB patients. Between May 2006 and May 2007, a total of 148 HCWs of the University Hospital in Nantes, France were tested simultaneously with IGRA und TST. A TST was considered to indicate recent latent TB infection (LTBI) if an increase of >10 mm or if TST >/= 15 mm for those with no previous TST result was observed. For those with a positive TST, chest X-ray was performed and preventive chemotherapy was offered. All HCWs were BCG-vaccinated. The IGRA was positive in 18.9% and TST >/= 10 mm was observed in 65.5%. A recent LTBI was believed to be highly probable in 30.4% following TST. Agreement between IGRA and TST was low (kappa 0.041). In 10 (16.7%) out of 60 HCWs who needed chest X-ray following TST the IGRA was positive. In 9 (20%) out of 45 HCWs to whom preventive chemotherapy was offered following TST the IGRA was positive. Of those considered TST-negative following the French guidelines, 20.5% were IGRA-positive. In a two-step strategy - positive TST verified by IGRA - 18 out of 28 (64.3%) IGRA-positive HCWs would not have been detected using French guidelines for TST interpretation. The introduction of IGRA in contact tracings of BCG-vaccinated HCWs reduces X-rays and preventive chemotherapies. Increasing the cut-off for a positive TST does not seem to be helpful to overcome the effect of BCG vaccination on TST.

    ABSTRACT: Sinonasal adenocarcinomas are uncommon tumors which develop in the ethmoid sinus after exposure to wood dust. Although the etiology of these tumors is well defined, very little is known about their molecular basis and no diagnostic tool exists for their early detection in high-risk workers. To identify genes involved in this disease, we performed gene expression profiling using cancer-dedicated microarrays, on nine matched samples of sinonasal adenocarcinomas and non-tumor sinusal tissue. Microarray results were validated by quantitative RT-PCR and immunohistochemistry on two additional sets of tumors. Among the genes with significant differential expression we selected LGALS4, ACS5, CLU, SRI and CCT5 for further exploration. The overexpression of LGALS4, ACS5, SRI, CCT5 and the downregulation of CLU were confirmed by quantitative RT-PCR. Immunohistochemistry was performed for LGALS4 (Galectin 4), ACS5 (Acyl-CoA synthetase) and CLU (Clusterin) proteins: LGALS4 was highly up-regulated, particularly in the most differentiated tumors, while CLU was lost in all tumors. The expression of ACS5, was more heterogeneous and no correlation was observed with the tumor type. Within our microarray study in sinonasal adenocarcinoma we identified two proteins, LGALS4 and CLU, that were significantly differentially expressed in tumors compared to normal tissue. A further evaluation on a new set of tissues, including precancerous stages and low grade tumors, is necessary to evaluate the possibility of using them as diagnostic markers.

    ABSTRACT: Where allergic investigations are carried out for occupational dermatitis, appropriate tests must be performed but commercially available batteries are not always suitable for the working conditions and for the products handled by patients. During testing, the products being handled must thus be correctly diluted with full knowledge of their composition in order to prevent harmful effects, particularly caustic effects, and to avoid false positives and false negatives.

    ABSTRACT: Contact dermatitis to epoxydic and phenolic resins are the most frequent contact dermatoses due to plastics, in particular in the form of airborne dermatitis. The chemical formulas of the various components of these resins and their additives are complex and the patch tests available in the trade are insufficient and often arrive at a late stage in the progress of industry, in particular in advanced technologies like aeronautical engineering, shipbuilding or the new floor and wall coverings in buildings. This article is a review of the actions to be taken with these allergies, as well as with regards to their diagnosis, prevention and medico-legal compensation.

    ABSTRACT: Occupational skin diseases of chemical origin are frequent among hairdressers. They can be caused by hair dyes, in particular those containing para-amines (especially paraphenylenediamine); bleaching agents containing alkaline persulphates, which can cause eczema, contact urticaria, rhinitis and asthma; liquids used in permanents containing products derived from irritant, sensitizing glycolic acid; irritant and sensitizing shampoos, in particular those with coconut derivatives, proteins hydrolysates and ubiquitous perfumes. Other allergic factors which are observed episodically include nickel, glutaraldehyde, formaldehyde, ethyl cyanoacrylate and minoxidil (Regaine®). Prevention, which is essential, should start at the beginning of the training.

    ABSTRACT: Objective The aim of this study was an evaluation of the occupational risk perceveid by the employees in a health care establishment in accordance with French legislation. Method An anonymous questionnaire based on JCQ, physical and environmental stressors was addressed to the employees. Employees were categorised by socioprofessional category (SPC), health care department or group, age, sex, professional statute. Results 1868 subjects were included in the study; major job strain was found in non specialized nurses, nurse aides and the health care executives. The main risk factors emerging are musculoskeletal symptoms in geriatric, orthopedics and traumatology departments, violence verbal and physical aggressiveness in psychiatric and emergency departments. Sleeping pills use seems related to a high psychological demand at work. It seems also related to a weaker social support. Analgesics consumption is related to perceived stress and musculoskeletal disorders.

    ABSTRACT: Occupational skin diseases (irritation, ulceration, urticaria and immunological eczema) to aldehydes, especially formaldehyde, glutaraldehyde and glyoxal, have been recognized for a long time in France as occupational diseases entitled to compensation. The occupational circumstances where these conditions are encountered are primarily in health care workers, particularely those who sterilize endoscopy, dental and dialysis instruments, who conserve tissues (especially in anatomy and pathology laboratories), those who use cooling fluids during machining of metals, who handle plastics containing formol derivatives, as well as those who have contact with certain textiles, cosmetics or nails hardeners. These allergens are very frequently encountered (formol is included in the standard battery of contact allergens), but it is expected that their use will decrease because of the now-recognized cancerogenic character of formol and the inefficiency of glutaraldehyde in sterilization against prions. Preventive measures against these aldehydes are therefore essential.
