ABSTRACT

OBJECTIVE: The aim of this study is to evaluate whether the exposure to a low dose of nickel could determinate a variation in levels of progesterone in outdoor workers. MATERIALS AND METHODS: Two hundred sixty one subjects were divided by sex, task, age, seniority, and cigarette smoking habit. For each workers was evaluated the dose of blood progesterone and urinary nickel.The statistical analysis was performed. RESULTS: The Pearson correlation showed a statistically significant correlation between urinary nickel levels and progesterone. The multiple linear regression showed a significant correlation between progesterone and urinary nickel in the total sample and in the subgroups of smokers and workers with tasks of traffic direction. CONCLUSIONS: The results of our study suggest that occupational exposure to low doses of nickel present in urban pollution may influence to progesterone levels in outdoor workers.

ABSTRACT

OBJECTIVE: To assess the risk factors for upper extremity-work-related musculoskeletal disorders (UE-WMSD) on 13 production lines in an airbag factory using the threshold limit values-American conference of industrial hygienists- hand activity level (TLV-ACGIH-HAL) method and introduce the ergonomic improvement to reduce the repetitiveness and the peak force (Pf). METHODS: Professional exposure level on 13 production lines in a automobile factory was measured using the TLV-ACGIH-HAL method and a further risk was assessed according to the ergonomic improvement. RESULTS: The first assessment of 9 production lines showed that the professional exposure level was above the TLV or HAL limit. The second assessment showed that the professional exposure level was below the AL limit on all production lines except 1, in which the professional exposure level was between TLV and HAL. CONCLUSION: The assessment of UE-WMSD-related risk can identify the riskiest emplacements and evaluate the reduction of risk in professional exposure through interventions of structural- organizational type.

ABSTRACT

INTRODUCTION: In health care the contact with body fluids, such as saliva or blood is frequent. The aim of our study was to analyze whether the exposure to biological risks in health care, in particular exposure to HBV and HCV, could cause alterations of some liver parameters. MATERIALS AND METHODS: Our study analyzes of 254 health care workers of a big hospital in Rome. The subjects exposed to biological risks were divided into two groups, one exposed to a high biological risk and the other one exposed to a low biological risk, according to individual duties and/or the departments where they carry out their work. We checked the markers for hepatitis B and C in order to highlight a possible infection, the possible vaccine coverage and the control of the antibody titer by previous infection. We measured the values of transaminases, GGT, alkaline phosphatase, total bilirubin and fractional proteinaemia total and electrophoresis. RESULTS: In health care workers exposed to high risk the average values of transaminases, total protein, alkaline phosphatase, gamma GT, total bilirubin were not significant compared to the some values formed in workers exposed to low risk (p > 0.05). Subjects positive for hepatitis B and C were 4% in the group of workers exposed to high risk (class 1) while in the group of workers exposed to low risk (class 2) the percentage of exposed individuals was 0.01% for the hepatitis B and 2.6% for hepatitis C. DISCUSSION AND CONCLUSIONS: We found a small numbers of positive cases of hepatitis B and C in people exposed to biological agents. We did not find alterations of the average values of transaminases, total protein, alkaline phosphatase, gamma GT, total bilirubin and albumin in positive cases, so that we can say that the proper use of personal protective equipment, training and information of workers and the observance of universal precautions are effective in protecting workers.
