Abstract

Blood and body fluid Exposure is a major occupational safety problems for health care workers. Therefor We conducted a descriptive and retrospective study to identify the characteristics of blood exposure accidents in health care settings which lasted five years (2005-2009) at the two university hospitals of Sfax. We have 593 blood exposure accidents in health care settings 152 (25.6%) health personnel and 441 (74.4%) trainees' doctors, nurses and health technicians. The mechanism of blood and body fluid exposure was accidental needle-stick injury in 78.9% of health staff, and 81% of trainees, accidental cut in 14.7% of health workers and 10.2% of trainees. The increasing severity of blood exposure accidents is linked to the lack of safe behavior against this risk. [ABSTRACT FROM AUTHOR]

Abstract

Objectives: To identify the determinants that influence the outcome of the return to work (RTW) after occupational injuries., Methods: We conducted a cross-sectional study at the National Health Insurance Fund of Tunisia among victims of occupational injuries. Individual and professional factors have been evaluated through a face-to-face questionnaire for ten months. Biomechanical exposure was estimated by the job-exposure matrix "MADE" and social support by the Social Support Scale. Along with descriptive statistics, we used bivariate analysis, binary logistic regression, and random forest., Results: We included 199 injured workers aged 20-60 years (mean = 42.73; 79.9 % male).Of the 199 injured workers, 39.7 % had unsuccessful RTW. Low social support, biomechanical exposure, blue-collar workers, working long hours, and severe injuries were associated with an unsuccessful return to work. In the variable importance plot issued from the random forest model, low social support at work was the most important risk factor of an unsuccessful RTW, followed by MADE variables: repetitiveness and effort., Conclusion: Biomechanical exposure and social support are main influencers of the return-to-work process., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Abstract

Introduction: Workaholism is an emerging form of behavioural addiction encountered in the workplace. The present study aims to assess the prevalence and the associated factors of this phenomenon in engineers., Methods: A cross sectional survey was conducted for two months by means of an online questionnaire of engineers practising in Tunisia. The evaluation of workaholism was based on the WART questionnaire (Work Addiction Risk Test)., Results: A total of 107 engineers have answered the questionnaire. The mean age of participants was 29.2±4.4 years. Computer engineers represented 32.7% of our sample. Most of engineers worked more than 8hours per day (45.8%) and less than 6 days per week (63.6%). A high risk of workaholism was noted in 42.1% of cases. Statistical analysis showed that workaholism was not associated with socio-demographic characteristics. However, it was associated with smoking cigarettes, psychotropic drug consumption and poly-addiction and inversely associated with the presence of a leisure activity. With regard to occupational factors, workaholism was associated with agronomic engineering, working more than 8hours per day, working the whole week and a job satisfaction score under 5/10., Conclusion: Workaholism interested a significant proportion of this sample, and several professional factors could increase the likelihood of adopting this behaviour. The intervention of occupational doctors seems important in order to raise awareness about this form of addiction and to identify its early signs among employees., (Copyright © 2022 L'Encéphale, Paris.

Abstract

Background: Healthcare professionals (HCPs) are exposed to multiple psychosocial risks that may lead to high levels of stress and low levels of life satisfaction and well-being. Mindfulness, defined as the awareness that arises by intentionally paying attention in the present moment and in a non-judgmental way, seems to be a moderator in the causal association between life stressors and well-being., Aims: The aim of the present study was to test the model of relationships between self-reported mindfulness, perceived stress, well-being index and life satisfaction in a sample of Tunisian HCPs., Methods: We performed a correlational cross-sectional study on a sample of HCPs at Hedi Chaker University Hospital, Tunisia. We used validated self-reporting instruments: the Mindful Attention Awareness Scale (MAAS), the Perceived Stress Scale (PSS), the World Health Organisation Well-Being Index (WHO-5) and the Satisfaction with Life Scale (SWLS). For data analysis, the SPSS version 23 program was used., Results: Participants (n=297) included staff nurses (49.2%), medical technicians (19.2%) and doctors (31.6%). The overall model revealed that reduced perceived stress (β=-0.30, P<0.000) and high levels of well-being (β=0.13, P=0.03) were associated with mindfulness, explaining 14% of the variance. Individually, perceived stress significantly predicted mindfulness explaining 13% of the variance., Conclusion: The study explores a variety of elements that can support the development of mindfulness interventions for stress prevention, staff well-being, and improvement of services as a whole., (Copyright © 2022 L'Encéphale, Paris.

Abstract

Vitiligo is a multifactorial dermatosis with many etiological hypotheses that have been suggested for its occurrence. To our knowledge, few epidemiological studies are available on vitiligo induction factors and particularly on the role of exposure to chemicals in the onset of the disease has been found. Therefore, there is need to investigate the relationship between vitiligo and chemical exposures in order to understand this mysterious disease. We conducted a case-control study of patients with vitiligo whose diagnosis was made by a specialist in dermatology. The total study period was of 6 months extending from 1 July to 31 December 2019. The minimum sample size was determined as 46 cases and 92 controls. The control group was gender, age, and professional status matched to the vitiligo group. In the binary logistic regression model, household chemicals/colored toothpaste use, a history of a repeated antibiotic use, and an occupational exposure to phenol/catechol derivatives were significantly associated with vitiligo (three to fourfold increase). Our results suggest that chemical factors play a key role in the occurrence of vitiligo. Therefore, prevention of this dermatosis requires the identification of exposure to the incriminated chemicals in any patient followed for vitiligo. The earlier the diagnosis of 'chemical' or chemically aggravated vitiligo, the better the prognosis for this disease.

Abstract

Objectives. This study aimed to explore the work productivity loss (WPL) due to musculoskeletal symptoms (MS) and its explanatory psychosocial, ergonomic and personal factors in Tunisian shoe and leather industry workers. Methods. We conducted a cross-sectional survey among 337 workers. We evaluated WPL using the work productivity and activity impairment questionnaire. We used the Nordic questionnaire to assess the MS prevalence, the job content questionnaire of Karasek to examine the psychosocial work environment and the quick exposure check (QEC) tool to estimate the ergonomic exposure levels. Results. The mean WPL was 44.9 ± 33%. In the multiple linear regression model, WPL was positively correlated with a history of MS, professional seniority, a rhythm perceived as restrictive, low social support and decision latitude, the number of symptomatic sites and the QEC strain level of the back. Conclusion. There was a decline in work productivity due to MS that results from a combination of personal, psychosocial and biomechanical factors. Once addressed, both work productivity and workers' well-being should be restored.

Abstract

Isothiazolinones, used as preservative, are known to be skin sensitizers. Although cosmetics represent their main source, occupational exposure may be a significant origin of eczema. While allergic eczema related to these derivates have been reported in a number of professional sectors, their presence in the same workplace was not common., Competing Interests: All authors have nothing to declare. They know of no conflicts of interest associated with this publication, and there has been no significant financial support for this work that could have influenced its outcome., (© 2022 The Authors.

Abstract

Purpose: Chronic occupational exposure to ionizing radiation (IR) induces a wide spectrum of DNA damages. The aim of this study was to assess the frequencies of micronucleus (MN), sister chromatid exchanges (SCE) and to evaluate their association with XRCC1 399 Arg/Gln and XRCC3 241 Thr/Met polymorphisms in Hospital staff occupationally exposed to IR., Materials and Methods: A questionnaire followed by a cytogenetic analysis was concluded for each subject in our study. The exposed subjects were classified into two groups based on duration of employment (Group I < 15 years; Group II ≥15years). The genotypes of all individuals (subjects and controls) were determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)., Results: DNA damage frequencies were significantly greater in IR workers compared with controls (p < .05). However, no association arised between XRCC1 399 Arg/Gln and XRCC3 241 Thr/Met polymorphisms, on one hand, and the severity of DNA damages in the studied cohort of Tunisian population, on the other hand., Conclusion: Our data provide evidence for an obvious genotoxic effect associated with IR exposure and reinforce the high sensitivity of cytogenetic assays for biomonitoring of occupationally exposed populations. These results indicate that workers exposed to IR should have periodic monitoring, along their exposure. The variants, rs25487 and rs861539, of XRCC1 and XRCC3 genes have obvious functional effects. Paradoxically, these variants are not associated with the severity of damages, according to used assays, in the studied cohort of Tunisian population, unlike other studies.

Abstract

This article describes a case of Pseudomonas aeruginosa keratitis resulting from projection of biological fluids (bronchial secretions) on the face, mainly in the right eye. The employee presented with keratitis complicated by a corneal abscess. Consequently, the employee had a chronic and severe ocular surface and stoma destruction, possibly due to microbial proliferation into the surface tissues exacerbated by contact lenses. The infection was determined to be work related by experts. [Workplace Health Saf 2014;62(10):400-402.]., (Copyright 2014, SLACK Incorporated.)

Abstract

Blood and body fluid Exposure is a major occupational safety problems for health care workers. Therefor We conducted a descriptive and retrospective study to identify the characteristics of blood exposure accidents in health care settings which lasted five years (2005-2009) at the two university hospitals of Sfax. We have 593 blood exposure accidents in health care settings 152 (25.6%) health personnel and 441 (74.4%) trainees' doctors, nurses and health technicians. The mechanism of blood and body fluid exposure was accidental needle-stick injury in 78.9% of health staff, and 81% of trainees, accidental cut in 14.7% of health workers and 10.2% of trainees. The increasing severity of blood exposure accidents is linked to the lack of safe behavior against this risk.

Abstract

The authors report the results of an investigation of witness cases realised in collaboration between Occupational Medecine Service and Immunology Laboratory of Hedi CHAKER University Hospital SFAX during the year 2000. The purpose was to search the genetic control of the HLA class I system for the non-response to hepatitis B vaccine and to evaluate the contribution of other favorite factors as tabac, sex, age. Thus, in a population of 32 healthy agents found nonresponders to hepatitis B vaccine by the titers of anti HBs antibody, we have performed the HLA-A, -B phenotypes by the technique of complement dependent microcytotoxicity. The frequency of studied HLA class I antigens, was compared for the non-responders group, to the frequency observed in witnesses group, done with 52 responders healthy agents. The rate of nonresponsiveness hepatitis B vaccine was evaluated up to 5 %. Statistically significant difference was observed for HLA A1 and-B44 markers showing fraquencies which were considerably higher in the non-responders than in witnesses.

Abstract

Mullerian structures were discovered during cure of bilateral ectopic testes in a 14-year-old boy. The original feature of this case was the presence of both testes on the same side. The Mullerian structures were left in place as they were intimately adherent to the vas deferens. This attitude was adopted as no degeneration of these structures has been described and because of the possibility of reproduction of these patients during adulthood.

Abstract

The purpose of our study was to evaluate the protective effect of a new silicone-containing barrier-cream (Anthydro) and its vehicle (Anthydro without silicone) in the prevention of cutaneous irritation by detergents. We therefore planned a study in several stages, using an anionic surfactant well known for its irritant properties: sodium laurylsulphate (SLS) in aqueous solution. In a first series of experiments, the protective effect of the Anthydro cream against SLS was studied by invasive methods on guinea-pigs in order to determine histologically the protective effect of the cream when a 10 p. 100 SLS solution was applied on the skin under occlusion during 24 hours (Square chambers, Van der Bend). Typical and reproducible lesions were apparent, and the protected sites were compared with the unprotected sites. In parallel, we used non-invasive methods (conductivity, transepidermal water loss and cutaneous blood flow) to determine in humans the protective effect of Anthydro cream in comparison with unprotected sites after application during 24 hours of patches soaked with a 5 p. 100 SLS solution on the forearms of 13 adult and healthy volunteers (Silver patch tests, Van der Bend). In both experiments the Anthydro cream was effective in reducing the SLS-induced cutaneous irritation. In a second series of experiments, the Anthydro barrier-cream was compared with its "base" (Anthydro without silicone) in terms of effectiveness, following the same experimental procedure (invasive on guinea-pigs, and non-invasive on humans). The base was shown to be effective in protecting against irritation. However, the histological lesions were less intense when the skin was protected by Anthydro than by its vehicle. Concerning the non-invasive methods in humans, no significant statistical differences appeared in the measurement of various parameters between the sites protected by Anthydro and the sites protected by the vehicle. These results lead us to suggest the existence of an essentially mechanical protective effect in which the silicone plays a very small part in terms of effectiveness. These experimental results necessitates further investigations to be extrapolated to occupational conditions without tests performed in industries and well-conducted epidemiological investigations.

Abstract

A positive "edge effect", i.e., the accumulation on the skin of a chemical solution (such as fluorescein 0.01% in a 50/50 water-ethanol solution) at the periphery of the patch test sites has been demonstrated. It occurs with different test materials (Finn Chamber; Silver Patch Test; Patch Test Chamber). Practical implications are discussed: this observation could be important when discussing results of laboratory investigations. In clinical practice, it could explain the occurrence of "ring-shaped" positive allergic patch test reactions to chemicals used in solution, i.e., Kathon CG or hydrocortisone.
