The aim of this study is to evaluate whether occupational exposure to urban stressors could cause alterations of systolic and diastolic blood pressure in "outdoor" workers. The research was conducted on a sample of 101 municipal policemen. The sample was divided in 2 groups according to length of service: group A (length of service between 1 and 15 years) and group B (length of service > 15 years). Group A and Group B were matched for age, overall length of service, cigarette smoking habit and consumption of alcohol and spirits. Group A was then divided into: Al (length of service between 1 and 7 years) and A2 (length of service between 7 and 15 years). The mean values of systolic and diastolic blood pressure at rest showed statistically significant differences with increased values in group B compared to both groups Al (p<0.05) and A2 (p<0.05). The study suggests that occupational exposure to urban stressors affects the blood pressure regulating system enhancing the risk of blood hypertension.

The aim of our study is to estimate if the occupational exposure to formaldehyde can cause alterations of leukocytes plasma values in health care workers employed in a big hospital compared to a control group. We studied employees in operating rooms and laboratories of Pathological Anatomy, Molecular Biology, Molecular Neurobiology, Parasitology and Experimental Oncology (exposed to formaldehyde) and employees of the Department of Internal Medicine (not exposed). The sample studied was composed of 86 workers exposed to formaldehyde and 86 workers not exposed. All subjects underwent a clinical-anamnaestic examination and for all subjects were measured the following values: total white blood cells, lymphocytes, monocytes and granulocytes (eosinophils, basophils, neutrophils). Statistical analysis of data was based on calculation of the mean, standard deviation and the distribution into classes according to the nature of each variable. Differences were considered significant when p was < 0.05. The mean and the distribution of values of the white blood cells, lymphocytes, monocytes and eosinophils were significantly higher in male subjects exposed to formaldehyde compared to not-exposed. Not significant differences were found in female subjects exposed compared to not exposed. The results underline the importance of a careful risk assessment of workers exposed to formaldehyde and the use of appropriate preventive measures. The health care trained and informed about the risks he is exposed to should observe good standards of behavior and, where it is not possible to use alternative materials, the indoor concentrations of formaldehyde should never exceed occupational limit values.

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.

Purpose: The aim of this study is to evaluate whether perceived stress in the workplace can be a risk factor able to change the blood counts in a group of male and female outdoor workers of the Municipal Police. The study examines possible relations among the levels of stress, as inferred from the scores of the questionnaire, blood counts and voluptuary habits., Methods: We evaluated a final sample of 486 subjects (345 males and 141 females). During the medical examination was performed for each subject: a) the administration of the questionnaire to assess the perception of work-related stress, b) the collection of clinical.anamnestic information related to the consumption of coffee, chocolate, alchool and smoking habit, c) the taking of a venous blood sample. All workers included in the study were divided into three groups on the basis of the scores of the questionnaire., Results: About 61% of workers showed a moderate or severe stress condition, with a statistically significant prevalence (p<0.05) of female workers and younger subjects. The increase of perceived stress coincided with a significant decrease (p <0.05) of the mean levels of white blood cells and with a significant increase (p <0.05) of the consumption of coffee, chocolate and smoking habit. There was no statistically significant differences for alcohol consumption., Conclusions: The results show that the stress induces a reduction of the white blood cells, an increase of coffee and chocolate consumption and of smoking.

The new D. Lgs. N 81, 2008 Article 28 paragraph 1 sanctions that the risk assessment must involve all the possible risks to safety and health of workers, including the work-related stress factors. Stressors at work may vary as to: quantity of work assigned, whether excessive or inadequate; lack of recognition or reward for good job performance; degree of responsibility; precariousness of work; emotional pressures exerted on workers; violence and harassment of psychological nature, poor balance between work and private life. The need man has to understand the causes of his psycho-physical and social disease are old. Only the words we use when dealing with the topic has changed over the time: once it was Alienation now it is Burn-out. The concept of alienation, which has been very important over the time, has many different aspects and has had countless interpretations (which have followed one another), the psycho-analytical, the sociological analysis and the Marxist one, Burnout is actually a syndrome characterized by three interrelated dimensions: exhaustion, cynicism and inefficacy. Therefore it is important to prevent, eliminate or reduce problems related to occupational stress. Among preventive measures, the Europe Agreement identified in the management and in the communication the information necessary to define the goals of the company and the role each employee has. Moreover information and formation are considered the necessary elements to increase awareness and understanding of the problem, its potential causes and possible ways of approading it. Our research group, has developed targeted questionnaires, biological indicators and medical instrumental examinations the occupational doctors can make use of to assess these issues.

Air pollution represents a health risk for people living in urban environment. Urban air consists in a complex mixture of chemicals and carcinogens and its effects on health can be summarized in acute respiratory effects, neoplastic nonneoplastic (e.g. chronic bronchitis) chronic respiratory effects, and effects on other organs and systems. Air pollution may be defined according to origin of the phenomena that determine it: natural causes (natural fumes, decomposition, volcanic ash) or anthropogenic causes which are the result of human activities (industrial and civil emissions). Transport is the sector that more than others contributes to the deterioration of air quality in cities. In this context, in recent years, governments of the territory were asked to advance policies aimed at solving problems related to pollution. In consideration of the many effects on health caused by pollution it becomes necessary to know the risks from exposure to various environmental pollutants and to limit and control their effects. Many are the categories of "outdoor" workers, who daily serve the in urban environment: police, drivers, newsagents, etc.

Aim of our study was to evaluate the influence that shift work and night work could have on mental health. A review of literary articles from 1990 to 2011 on shift work and night work was carried out. The results of this review confirmed that the shift work and night work affect mental health with the onset of neuropsychological disorders such as mood disorders, anxiety, nervousness, depressive anxiety syndromes, chronic fatigue and chronic insomnia irritability, sleep disturbances, reduction in levels of attention, cognitive impairments, alteration of circadian rhythm. Night work and shift work cause severe desynchronization of the cronobiological rhythms and a disruption of social life with negative effects on performance at work, on health and on social relationships. In the light of these results and recognizing shift work and night work as risk factors for the health of workers is necessary to implement preventive and periodic health checks by the occupational doctor to ensure the health and safety of workers taking account of the different environmental and individual factors.

The relation between stress and new technologies has always been a vexed question. Experts say technology is a sort of double-edged weapon; it increases the potential of human senses but on the other hand it also involves an adjustment to artificial, unnatural rhythms which have consequences on mental and physical health. Through tests with patients not too prone to socializing Cognitive Ergonomics shows that using web in a correct guided interactive way, instead of the passive way of using media, helps developing concentration and reactivity and improves the way we come into contact with the world around us.
