Quality of Life of Healthcare Workers Suffering from Occupational Contact Dermatitis.

BACKGROUND: Healthcare workers are at a high risk of developing Occupational Dermatitis (OD). Affected workers often experience severe impairment of their Quality of Life (QoL). This study aimed to assess the skin-related QoL of healthcare workers with OD and to explore its related factors. METHODS: A cross-sectional and exhaustive study was conducted among healthcare personnel of four public hospitals in the central region of Tunisia. All the cases of OD declared were included. Skin-related QoL was assessed using the validated Tunisian version of the "Dermatology Life Quality Index" (DLQI). Some related patents have also been discussed. RESULTS: A total of 37 cases of OD were collected with an annual incidence of 4.2 cases per 10000 workers. The population was predominantly female (73%) and the mean age was 44.7±9.4 years. Nurses were the most represented occupational category (38%). Allergic contact dermatitis was the most frequent diagnosis (96%). The use of gloves was the most frequently reported occupational hazard (86%). The most frequently affected sites were hands (97%). The median score of DLQI was five. Multivariate analysis showed an association between the impairment of skin-related QoL and female gender (p = 0.04; OR = 19.3,84), exposure to disinfecting chemicals in the workplace (p = 0.01; OR = 17,306) and the absence of occupational reclassification (p = 0.01; OR = 21,567). CONCLUSION: About one-third of the population had an impaired quality of life. The score impairment was significantly related to the female gender, exposure to disinfecting chemicals and the absence of occupational reclassification.

[Semi-quantitative ergonomic analysis of the biomechanical constraints within the cervical spine among screen-operators in the Tunisian universities]. / Analyse ergonomique semi-quantitative des contraintes biomécaniques du rachis cervical parmi les opérateurs sur écran dans les établissements universitaires tunisiens.

INTRODUCTION: This study aims to evaluate the biomechanical constraints associated with neck pain among screen-operators. METHODS: We conducted an ergonomic study of 325 screen-operators in 25 Tunisian universities based on an anthropometric evaluation of on-screen work and on a semi-quantitative analysis of video recordings of the activities of employees over a representative period of 30 minutes. RESULTS: The prevalence of neck pain was 72.3% in a working population who had to seat in an unsuitable chair and to use an unsuitable worktop (84.6%) and a screen too low with regard to horizontal gaze (81.2%). A semi-quantitative analysis, using video recording of the workstation, concluded that the nape flexed more than 40 degrees for 69% of overall working time. Lateral flexion was observed for 50.3% of working time and right or left rotation for 57.4% of working time. Thus, the most limiting head posture on a postural and gestural level was observed when screen-operators read on a computer screen, had an incorrect positioning of the keyboard and consulted documents. CONCLUSION: Our results highlight the importance of biomechanical constraints associated with a design of on-screen work which is not in accordance with the ergonomically recommended anthropometric dimensions. These constraints are associated with a high prevalence of neck pain, reflecting the need to ensure an ergonomic design of workstations in order to prevent this problems.

The Quality of Life and Professional Future among Tunisian Workers Suffering from Occupational Asthma.

OBJECTIVE: To identify the factors influencing the quality of life and professional future of patients suffering from occupational asthma. METHOD: A cross-sectional study of patients compensated for occupational asthma in Tunisian center during 2004-2011. The study of quality of life was based on the Asthma Quality of Life Questionnaires (AQLQ). Some related patents were also discussed. RESULTS: One hundred twenty-nine patients were compensated and the mean age was 40.8 ± 7.6 years. The global score of quality of life was 3.65 ± 0.75. The group of employees having a "bad quality of life" included 82 patients (77.3%), 73 patients kept the same job (56.6%), 20.9% had an occupational reclassification, 13.9% were dismissed, 6.2% abandoned their job and 2.3% were put in disability. The analytical study of the quality of life showed that: - The global score was correlated with the fact of keeping the same job and the application of preventive measures. - The score in the "symptoms" area was correlated with working in the textile sector and the association with an occupational rhinitis. - The score in the "activity limitation" area was correlated with age. The analytical study of the professional future revealed that maintaining the same job was correlated with low rates of permanent partial disability. CONCLUSION: Our study revealed the need to implement early preventive measures and to establish a systematic review of the permanent partial disability rate attributed to workers suffering from occupational asthma before the end of the legal period of five years.

[Occupational asthma compensation in the Tunisian Center: cross-sectional study over a period of eight years]. / Asthme professionnel indemnisé dans le centre tunisien: étude ransversale sur huit ans.

INTRODUCTION: Our study aimed to highlight the epidemiological profile of patients compensated for occupational asthma in the Tunisian Center, to identify their professional characteristics and to determine compensation practices for this occupational disease. METHODS: We conducted an exhaustive retrospective study over a period of eight years. This case study included workers with occupational asthma diagnosed and compensated in the Tunisian Center by the only two medical commissions empowered to set rates for permanent partial disability caused by either a work-related injury or an occupational diseases in the seven central governorates. RESULTS: A total of 129 workers, with average age of 40.6 ± 7.75 years were compensated for occupational asthma during the study period. Sex ratio was 0.66. The most incriminated etiologic agents were vegetable dust pollution in the textile industry (75.2%), wood dust, flour and isocyanates. Nonspecific bronchial hyperreactivity was found in 38% of cases, a high rate of IgE in 14% of cases and positive skin prick test in 10.9% of cases. The average rate of permanent partial disability was 25.6 ± 14.2%. On the basis of the analytical study, this rate was related to patient's age and to the medical commission which had set this rate. CONCLUSION: This study of workers compensated for occupational asthma provides relevant data about epidemiological and clinical features of diagnosed patients and committee practices in particular, in term of application of the voluntary indicative scale, but it does not allow an assessment of the prevalence of this pathology which is often underestimated.

[Socio professional impact of surgical release of carpal tunnel syndrome]. / Impact socio professionnel de la libération chirurgicale du syndrome du canal carpien.

The objective was studying the socio-professional impact of release surgery for carpal tunnel syndrom (CTS). We conducted a cross-sectional study of patients operated for work-related CTS; data were collected in the Occupational Health Department at the University Hospital Tahar Sfar in Mahdia, Tunisia over a period of 8 years, from 1 January 2006 to December 2013. Data collection was performed using a survey form focusing on participants' socio-professional and medical characteristics and on their professional future. We used Karasek's questionnaire to study psychosocial constraints at work. The duration of a work stoppage following release surgery for CTS was significantly related to the existence of musculoskeletal disorders other than CTS, to a statement that the carpal tunnel syndrome was work related and to job seniority. As regards the professional future of operated employees, 50.7% remained in the same position, 15.3% were given customized workstation and 33.8% were offered a different position within the same company. The professional future of these employees was related to their occupational qualifications and to the type of sensory and/or motor impairment of median nerve detected during EMG test. A number of nonlesional factors determines the duration of the work stoppage, while the professional future of patients operated for CTS essentially depends on their professional qualifications and on EMG data. Certainly much broader studies would allow to refine these results.

Work related asthma in the textile industry.

Nowadays, occupational asthma is the most common form of occupational lung disease in the world. In some countries the textile industry remains an important source of potential agents causing occupational asthma. In the textile industry several agents such as cotton dust and dyes may cause occupational asthma. In this review, we discuss the epidemiology, pathogenesis/mechanisms, clinical presentations, management and prevention specific to occupational asthma in the textile industry.Work-related asthma risk is considerable. Current understanding of the mechanisms by which many textile agents cause occupational asthma is limited, especially for low molecular-weight sensitizers and irritants. The diagnosis is generally established on the basis of a suggestive history of a temporal association between exposure and the onset of symptoms and objective evidence that these symptoms are related to airflow limitation. Early diagnosis, elimination or reduction of exposure to the offending agent and early use of convenient therapy according to disease severity may play an important role in the prevention of long-term persistence of asthma. Its prevention in the textile industry should be both technical and medical. It depends on the difficulties to reduce dust level, the limits in arranging work station or in occupational rehabilitation. These difficulties are increased in small textile industry companies. Persistent occupational asthma in this sector is often associated with substantial disability and consequent impacts on income and quality of life. Prevention of new cases is the best approach to reduce the burden of asthma attributable to occupational exposures. This review also outlines different patents on the diagnosis and treatment of asthma.
