Introduction: The exposure to shift works, and especially to night shift, goes against the circadian rythmicity of the social man, which brings about a multitude of disruptive effects on health. In a hospital environment, such night shift is necessary so as to ensure the continuity of care. Sleep and vigilance disorders related to this work mode are frequent and often pose adaptation problems. The objective of this study is to detect the harmful effects of night shift on sleep, vigilance and the quality of life of nurses in Farhat Hached Teaching Hospital in Sousse. Material and Methods: It is a cross-sectional study carried out among two groups of nurses: one group performing a fixed night work and the other one working permanently during the day at Farhat Hached Teaching Hospital in Sousse. Data collection is mainly based on validated questionnaires evaluating sleep quality (Pittsburg sleep quality index), daytime sleepiness (Epworth sleepiness scale), sleep typology (Horne and Ostberg questionnaire), and the quality of life (SF-12). An objective evaluation of vigilance was realized by the study of reaction time and error rates to different tasks of “Super lab” software. Results: 50 night and 50 day nurses have been colligated. Both groups were age- and gender-matched. Sleep quality mean index was significantly higher among night nurses in comparison with day nurses (10.2 ± 5.9 versus 6.76 ± 5.16). After multivariate analysis, sleep quality was significantly correlated to age, department, schedule and the choice of schedule. Night shift was not related to daytime sleepiness. The objective analysis of vigilance showed that the reaction time to different tasks exploring the attentional mechanisms, as well as errors rate, were significantly more important among the night group. The mental score of the quality of life was significantly higher among day nurses. However, such difference was not significant with regard to physical score. Conclusion: The findings of our study highlight not only the alteration of the health and the well being of paramedical staff secondary to night shift, but also a possible threat to safety care lavished by these teams, which involves the necessity to undertake preventive measures on an individual and collective scale. 展开更多

Colorectal cancers (CRC) account for frequent and serious cancers which result from the interaction between individual genetic factors and environmental factors, and in particular widely studied nutritional ones. The role of other occupational factors remains a controversial subject. The objective of this study is to evaluate the possible impact of occupational factors on the risk of developing CRC. Materials and Methods: This is a retrospective case-control study. The cases and the control group were enlisted in the general surgical ward of Farhat Hached Teaching Hospital of Sousse (Tunisia) during the period extending from 2004 to 2008, and they were age and gender-matched. The data were analyzed using SPSS 11.0 software with a signification threshold fixed at 5%. A univariate analysis was carried out as well as a multiple binary logistical regression. Results: During the period of the study, 40 cases of colorectal cancers have been colligated including 28 men and 12 women with a sex ratio of 0.43. The average age of the cases was 61.55 ± 13.3 years and 60.40 ± 12.84 years for the control group, with a non significant difference (P = 0.69). The univariate analysis has objectivized significant associations between colorectal cancer and the housing conditions, the neoplastic and digestive family history, the occupational activity sector, exposure to pesticides, and lack of periodic medical supervision. After logistical regression, the occurrence risk of CRC was significantly associated with: alcohol and smoking (ORa = 3.43; Pa = 0.05), meat consumption (ORa = 3.34; Pa = 0.03), exposure to pesticides (ORa = 20.44; Pa = 0.012) and lack of periodic medical supervision (OR = 7.45; P = 0.004). Conclusion: The occupational risk factors might play a role in the etiopathogenesis of colorectal cancers. With regard to our study, pesticides seem to be most implicated and necessitate suitable preventive measures. Nevertheless, it seems useful to multiply the studies to a much larger scale in order to further explore such relationship and to further reinforce the prevention of such serious disease. 展开更多
