Screening for Early Detection of Asymptomatic Coronary Artery Disease (Secondary Prevention): An Approach to Cost/Benefit and Cost/Effectiveness Analysis

Classification of different types of preventive measures for ischemic heart disease (IHD) has been much debated. In the classical use of terms “primary prevention” (prevention of occurrence) includes removal of risk factors in otherwise healthy individuals, while the attempts to change diet and life style in the very early age, in order to avoid the acquisition of risk factors, has been called “preprimary prevention” or “early prevention.”

Valutazioni igienico-sanitarie delle acque in tre invasi artificiali della provincia di Palermo destinate al consumo umano

We report the physico-chemical and bacteriological characteristics of three Sicilian reservoirs. The aim of this study was the evaluation of the reservoirs' sanitary conditions, given tha the water is also used for human consumption. 114 samples (4 locations at each lake) were collected in the period from July 1995 to June 1996. We analysed temperature, pH, oxygen saturation, colour and parameters of water mineralization and pollution of natural or human origin.Pathogenic bacteria (Salòmonellae) and opportunistic patjogens such as Pseudomonas aeruginosa and Aeromonas spp. were also investigated. At present, results are not showing particular levels of pollution, and it seems there is no ris…
