In the above brief note, the authors discuss the validity of sterilization with ethylene oxide in hospital. The use of this agent requires most accurate attention by the operator and precise specific indication in view of the many negative factors which limit its widespread use, above all its marked toxicity and the fact that it is not easy to handle.
The risk of pollution by anesthetic gases in operating rooms is examined and the pathologies that can affect exposed personnel are analyzed. As to prevention, measures for ensuring safety of devices used in operating rooms are indicated, as well as procedures for monitoring environment and personnel.
Radon is the most serious cause of human irradiation and can accumulate indoors in large quantities. The authors examine some aspects of human exposition to natural radioactivity, survey the Italian and international literature on indoor radon concentrations, and finally, set out some guidelines for prevention and control of radon pollution.

The main risk factors for cardiovascular disease which are amenable to intervention for prevention are described. These include smoking, hypertension, hypercholesterolaemia, obesity etc. These risk factors can be ranked in order of importance according to the ratio of the attributable risk to the prevalence of the exposure to the factor in the population.

The preliminary data of a policentric study for the determination of the blood-pressure values and the risk factors associated with high-blood pressure are reported for establishing a prospective epidemiological research. This research involved 258 children attending nursery, elementary-school in the city of L'Aquila. The weight, height, the triceps-skin-fold, the heart-rate, the blood systolic and diastolic-pressure (fifth tone) were examined. Furthermore the parent who accompanied the child was given a questionnaire in order to define: the general information concerning the child and the parent, the family anamnesis concerning the pathology correlated to the high-blood pressure, the child's weight at birth and the thronging-index (the ratio of the number of the family members with respect to the number of the habitable rooms). The obtained data show, especially for the PAS, higher blood-pressure values (greater than 95. percentile) in the grown-up subjects and in the male. The close correlation between the heart rate, BMI and the weight at birth, on one hand, and the blood-pressure values on the other hand, show, besides the validity of the research carried out, the connection between the blood-pressure situation and other physiological, paraphysiological and pathological factors. In conclusion, observing that a considerably high percentage of subjects with high-blood pressure values (5.8%' is one important result, especially for the future implications that it can have; it has to be defined if this situation has a prediction value of constant high-blood pressure in the adult and in what measure the examined factors influence the stabilization of this pathological situation.
Indoor atmospheric pollution includes a lot of pollutants coming partly from outdoors and produced partly by internal sources. Concerns about potential public health problems are based on evidence that urban residents typically spend more than 90 percent of their time indoors and concentrations of some contaminants are higher indoors than outdoors. Adverse effects of indoor air pollution are obviously dependent on the type of pollutant; among the more important indoor contaminants are passive tobacco smoke, radon decay products, carbon monoxide, nitrogen dioxide, formaldehyde, asbestos fibers, microorganisms and allergens. Efforts to assess health risks associated with indoor air pollution are limited by insufficient information about the number of people exposed, the pattern and severity of exposures and the health consequences of exposures. An overall strategy should be developed to control sources, dilute indoor contaminants and promulgate specific regulations.
