The objectives of our study are to evaluate the prevalence of low back pain among nurses and to look for physical and psychosocial risk factors. Methods: It is a cross-sectional study based on a self-administered questionnaire destined for all nurses working in Farhat Hached Teaching hospital of Sousse (Tunisia). Results: Our study included 203 nurses with an average age of 39.8 years. The prevalence of low back pain over the last twelve months was 58.1%. The factors that are significantly associated to low back pain were: high BMI, number of pregnancies, arthritis, poor physical condition, daily frequency of inappropriate posture for the activity being performed, and the layout of materials in the workplace. Conclusion: Our study evidenced the high prevalence of LBP among nurses and allowed bringing to light the role of individual and ergonomic physical factors in the genesis of LBP. Such identification permits to undertake targeted preventive actions. The association between psychosocial factors and LBP was not emphasized.展开更多

The ICSI, technique of reference in severe male infertilities, is visavis unexplained failures whose environmental and professional exposure could be about its cause partly. In this work, we tried to highlight an association between certain factors of professional exposure and the deterioration of the spermatic parameters, then to evaluate the effect of such factors on the result of the ICSI. Materials and Methods: It is about a study of the exposed type—no exposed, realized through collaboration between the Unit of Medicine of the Reproduction and the Service of Medicine of Work of the CHU Farhat Hached of Sousse. This study was based on a questionnaire of which part of the items was collected medical files of the patients raising the general characteristics, the profile of exposure as well as the spermatic parameters and the biological assessment of ICSI. Results: Significant associations between the deterioration of sperm and the professional risk factors such as the exposure to the formaldehydes (p = 0.01) and heat (p = 0.001) were noted. The exposure to formaldehydes was associated at the higher risk of oli gozoospermy, of asthenozoospermy with a significant reduction in mobility (p = 0.05), whereas the talks with cement had a risk higher of teratozoospermy. In addition an exposure to heat was associated at the high risk of oligoteratozoospermy. The total rate of pregnancies after ICSI among 220 patients of our series was of 14.47%. The ICSI balance showed a reduction in total fertility rate (76.6% exposed vs 75.3% no exposed). Conclusion: In spite of the limited number of the patients, this study had shown a correlation between certain professional exposures of origin and the deterioration of sperm. They are preliminary results which encourage continuing collaboration between the specialists in the reproduction and the doctors of work in order to preserve the fertility of the workers exposed to factors gonadotoxic.展开更多
