[Environmental risk factors and epidemiologic study].

The problems regarding communication of risks in the environmental sector and the analysis of certain causes of pollution, together with their effects on human health are the subjects of this article. In an illustrative and concise manner results of the most important epidemiological studies concerning the effects of non-ionizing radiations, of radon and of air pollution have been analyzed. Throughout this analysis emphasis has been placed on the difficulty of obtaining clear and scientifically based results. Such results are needed in order to provide the population with satisfying information and thus meet the increasing demand for unambiguous answers. Among the risk factors for human health are the high frequency electromagnetic fields used for mobile phones (radiofrequency--RF) nd extremely low frequency electromagnetic fields (ELF-EMFs) of power-lines. Even though these risk factors may be minimal the high number of persons exposed could make them an important impact on public health. Regarding the topic of air pollution, effects on particular segments of the population (children, elderly people and subjects with chronic diseases) have been found in various studies; for example, for an increase of PM(10) of 10 microg/m(3) an increase in daily mortality of 0.69% (CI 0.40-0.98) due to cardiovascular and respiratory causes has been estimated as well as an increase in general daily mortality of 0.54% (CI 0.33-0.76). Due to the populations' low risk perception (caused by unawareness of the problem) radon is undoubtedly the environmental pollutant which has the most impact on public health. This is true even in Italy where 4,000 cases of lung cancer attributable to radon (about 11% of total lung cancer) have been estimated per year; this risk is heightened by the combined effect with smoking. When dealing with health risks the tools of communication must be simple and correct; the mass-media are the most important mediators between the scientific community and the public. It is therefore vital for the public health operators to maintain a continuous relationship with the mass media which should be based on reciprocal trust and full collaboration.

[Risk management in health care systems: the new legislative orientations in medical civil responsibility].

The recent radical change in the relationships between physicians and patients has increased the frequency of malpractice. Consequently, on one hand, many physicians got used to avoiding any possible risk of denunciation by applying the so called "defensive medicine", while on the other hand, the insurance companies raised the prices of their premiums for policies concerning civil responsibility of health operators. In order to avoid this "vicious circle", some health structures created Units for the Risk Management related to malpractice, while others took advantage of the collaboration of Associations for Patients' Rights to create database about the most frequent medical mistakes. The need for a legislative change has been accepted by the Parliament which expects with the proposal n.108 (approved in spring 2002 by the Commission for Hygiene and Health of the Senate) to attribute the civil responsibility of the physicians to the hospitals (both private and public) for which they work, to constitute a Register of experts and to accelerate the legal disputes. The problem is complex and still to be solved, but it seems that time for a strong intervention in order to improve the situation has to come.

[Microbial air monitoring in operating theatre: active and passive samplings].

Microbial air contamination was evaluated in 11 operating theatres using active and passive samplings. SAS (Surface Air System) air sampling was used to evaluate cfu/m3 and settle plates were used to measure the index of microbial air contamination (IMA). Samplings were performed at the same time on three different days, at three different times (before, during and after the surgical activity). Two points were monitored (patient area and perimeter of the operating theatre). Moreover, the cfu/m3 were evaluated at the air inlet of the conditioner system. 74.7% of samplings performed at the air inlet and 66.7% of the samplings performed at the patient area before the beginning of the surgical activity (at rest) exceeded the 35 cfu/m3 used as threshold value. 100% of IMA values exceeded the threshold value of 5. Using both active and passive sampling, the microbial contamination was shown to increase significantly during activity. The cfu values were higher at the patient area than at the perimeter of the operating theatre. Mean values of the cfu/m3 during activity at the patient area ranged from a minimum of 61+/-41 cfu/m3 to a maximum of 242+/-136 cfu/m3; IMA values ranged from a minimum of 19+/-10 to a maximum of 129+/-60. 15.2% of samplings performed at the patient area using SAS and 75.8% of samplings performed using settle plates exceeded the threshold values of 180 cfu/m3 and 25 respectively, with a significant difference of the percentages. The highest values were found in the operating theatre with inadequate structural and managerial conditions. These findings confirm that the microbiological quality of air may be considered a mirror of the hygienic conditions of the operating theatre. Settle plates proved to be more sensitive in detecting the increase of microbial air contamination related to conditions that could compromise the quality of the air in operating theatres.

[Management of the visual risk in VDT workers and the role of the occupational physician (Medico competente)].

The enormous increasing of computer use in work activities has carried great progresses and many other advantages, but it has brought also possible health problems for the workers. The occupational risk in VDT workers involves the visual system, work-related muscoloskeletal disorders and also the mental state. This article concerns the major problems related to the obligations of the employer and to health surveillance, with special care to ophtalmologist examination for the ability, the responsibility and duty of occupational physicians (medici competenti) and the possible role of the ophthalmologists.

[Degree in prevention techniques for the environment and the workplace: distribution of credits and proposal for a unified training programme].

A revision of the training programmes of the Degree in Prevention techniques in the environment and at the workplace was carried out in order to appraise the present distribution of the credits (CFU) and to propose a common training programme that holds account of the core curriculum, of the present situation and of the training requirements that are emerging so far. In a lot of teaching programmes emerged the deficiency of juridical and psico-social matters that appear fundamental for the training of this Technician while the bio-medical disciplines seem too much represented. General and applied hygiene (SSD MED/42), Occupational medicine (MED/44) and the Applied physics (FIS/07) are the three disciplines activated in all the 25 curricula analysed. The Hygiene is the discipline with the average higher number of CFU (mean of 9.97 with ranks from 2.5 to 21.6).
