a b s t r a c tBackground: Among healthcare professions, critical care healthcare workers (HCWs) have one of the most stressful jobs. This study was conducted to determine the relationship between job stress and burnout syndrome (BOS) among nurses and healthcare technicians at the surgical emergency department and intensive care unit of Critical Care department at the Alexandria University Hospital. Methods: A cross-sectional approach was conducted from October 2014 to March 2015. Eighty-two nurses and healthcare technicians participated in the research (response rate = 80.39%). Data was collected by an interview questionnaire using selected subscales of NIOSH Generic job stress Questionnaire and Maslach Burnout Inventory of Health and human service Questionnaire. The relationship between BOS and job stress was examined using bivariate and multivariate analyses. Results: Although majority of participants reported variation of workload (84.15%), quantitative overload (76.8%), responsibility for peoples' life (69.5%) and lack of perceived control (63.41%), yet, 85.4% were satisfied with their job. Moreover, high levels of emotional exhaustion was reported by the majority of participants (80%), while less than one third reported either high levels of depersonalization or low levels of personal accomplishment domains of BOS. In multiple regression analysis, skill underutilization, variation in workload, and intragroup conflicts were negatively associated with BOS domains. While, job satisfaction and responsibility for peoples' life were positively associated with personal accomplishment domain of BOS. Conclusion: Critical care HCWs had high BOS. The study concluded that reducing intragroup conflict, improving skills utilization, and raising job satisfaction are crucial to reduce BOS among critical care HCWs. More attention and psychological support is recommended to critical care HCWs. Ó 2017 Alexandria University Faculty of Medicine. Production and hosting by Elsevier B.V.

Background: Formaldehyde can be toxic, allergenic and carcinogenic. Evaporation of formaldehyde from formalin-treated cadavers in the anatomy dissection rooms can produce high exposure. This study was conducted to assess acute and chronic toxic effects of formalin-treated cadavers on medical students, staff members, and workers at the Anatomy department in the Alexandria Faculty of Medicine (AFM). Methods: A cross sectional approach was adopted to investigate medical students (n = 454). Staff members and workers at the Anatomy department (n = 16), and unexposed staff members and workers in the AFM (n = 19) were included in the study. Medical students filled self-administered predesigned questionnaire. Formalin-exposed and unexposed staff members filled a questionnaire and a Complete Blood Count was done for them. Results: The most frequently reported symptoms by medical students were unpleasant smell (91.2%), itching in the eyes (81.3%), and excessive lacrimation (76.1%). Majority of them reported duration of relief within one hour (>80%), and more than two thirds reported wearing laboratory coats and hand gloves. Formalin-exposed staff reported symptoms of skin disorders as drying (75%), eczema (68.8%), and allergic contact dermatitis (87.5%), besides, eye irritation (68.8%), respiratory tract irritation (93.8%), and workrelated bronchial asthma (53.3%). The mean RBCs and platelets counts were significantly lower among formalin-exposed staff (4.08 ± 0.65 Â 10 6 /ul and 237,375 ± 71745.73/ul respectively) compared with unexposed staff (4.95 ± 0.50 Â 10 6 /ul and 280473.68 ± 54456.27/ul respectively). WBCs count was abnormal (low or high) among formalin-exposed staff members (6.2%, and 18.8% respectively), while all unexposed staff had normal WBCs counts. Conclusion:The research highlighted the irritating action of formalin on medical students, and chronic toxic effects on staff members. This necessitates re-evaluation of the concentration of formalin, proper ventilation and assessment of working practices in the dissecting rooms at the Anatomy department.

Background: Of the estimated 384,000 needle-stick injuries occurring in hospitals each year, 23% occur in surgical settings. This study was conducted to assess safe injection procedures, injection practices, and circumstances contributing to needlestick and sharps injures (NSSIs) in operating rooms. Methods: A descriptive cross sectional approach was adopted. Modified observational checklists based on World Health Organization (WHO) definitions were used in operating rooms (n = 34) and interview questionnaire was administered to HCWs (n = 318) at the Alexandria Main University Hospital. Results: Safe injection procedures regarding final waste disposal were sufficiently adopted, while measures regarding disposable injection equipment, waste containers, hand hygiene, as well as injection practices were inadequately carried out. Lack of job aid posters that promote safe injection and safe disposal of injection equipment (100%), overflowing of sharps containers and presence of infectious waste outside containers (50%), HCWs not cleaning their hands with soap and water or alcohol-based hand rub (58.1%), and HCWs not wearing gloves during IV cannula insertion (58.1%), were all findings during observations. High prevalence of NSSIs was reported (61.3%), mostly during handling suture needles (50.8%). In addition, 66.2% of the injured HCWs were the original user of the sharp item which was contaminated in 80% of injuries. At time of NSSI, 79% HCWs were wearing gloves. The most common injured sites were left fingers (39.5%), and 55.4% of injuries were superficial. After exposure, 97.9% did not report their exposure. The source patient was not tested for HBV, HCV and HIV infection in more than 70% of injuries and 96.9% of injured HCWs did not receive post exposure prophylaxis. Conclusion: The study highlighted that inadequately adopted safe injection procedures and insufficient injection practices lead to high prevalence of NSSIs in operating rooms.

Background: Globally, there is an expansion in computer-related work, which may have contributed to an increased burden of complaints of the arm, neck and/or shoulder (CANS). The study was conducted to determine the prevalence and factors associated with CANS among computer office workers (OWs) in Alexandria. Participants and Methods: Computer OWs at four banks and two telecommunication companies (n=211) were included in a cross-sectional study in 2016. Data were collected using the self-administered Musculoskeletal Upper Extremity Questionnaire-Arabic version. Potentially related factors were examined using bivariate and multivariate analyses. Results: The sample comprised 95 (45.02%) males and 116 (54.97%) females. Overall, 72% aged 25-35 years. Prevalence with 95% confidence interval (CI) for CANS was 0.73 (95% CI: 0.66-0.79), 0.69 (95% CI: 0.62-0.75) and 0.70 (95% CI: 0.64-0.76), respectively. The majority of the complaints were minor (86%). Factors significantly associated with neck complaints were female sex (P=0.03), inappropriate office equipment (P=0.02), task complexity (P<0.01), break autonomy (P=0.02) and low decision authority (P=0.05). Factors significantly associated with arm/hand complaints were female sex (P=0.01), awkward body posture (P=0.05), break autonomy (P<0.01) and low break quality (P=0.04) Conclusion: The study revealed high prevalence of CANS and highlighted associated factors, namely, task complexity, inappropriate office equipment, low decision authority, low break quality and female sex. Improving ergonomic conditions, reducing job demands, and increasing job control are crucial to reduce CANS among computer OWs.

Background Few data were documented about risk factors for lower limb varicose veins (LLVV) among Egyptian population. Identifying modifiable risk factors is crucial to plan for prevention. The current research aims to study the epidemiological, life style, and occupational factors associated with LLVV in a sample of Egyptian population. Methods A case control study was adopted. Cases with LLVV (n = 150) were compared with controls (n = 150). Data was collected using an interview questionnaire and clinical assessment. Data was analyzed using the univariate and multivariate logistic regression analyses. Results According to multivariate analysis among all participants (n = 300), the odds of LLVV was 59.8 times greater for those who frequently lift heavy objects (95% CI = 6.01, 584.36) and 6.95 times higher for those who drink < 5 cups of water/day (95% CI = 2.78, 17.33). Moreover, it was 4.27 times greater for those who infrequently/never consume fiber-rich foods (95% CI = 1.95, 9.37) and 3.65 times greater for those who stand > 4 h/day (95% CI = 1.63, 8.17). Additionally, odds of LLVV was 3.34 times greater for those who report irregular defecation habit (95% CI = 1.68, 6.60), and 2.86 times higher for those who sleep < 8 h/day (95% CI = 1.14, 7.16), and 2.53 times higher for smokers compared with ex-smokers/non-smokers (95% CI = 1.15, 5.58). In addition, a standing posture at work was an independent predictor of LLVV among ever employed participants (n = 234) in the current study (OR = 3.10; 95% CI = 1.02, 9.38). Conclusions This study highlighted seven modifiable independent predictors of LLVV mostly related to the life style, namely, frequent lifting of heavy objects, drinking < 5 cups of water/day, infrequent/no consumption of fiber-rich food, standing more than 4 h/day, irregular defecation habit, sleeping less than 8 h/day, and smoking. These findings provide a basis to design an evidence-based low-cost strategy for prevention of LLVV among Egyptian population.
