The program Hepascore was produced by an interdisciplinary group working in the Laboratory of Clinical Informatics of the San Giovanni Battista Hospital in Turin with the aim of supporting physicians in the early diagnosis of hepatic damage and in its qualitative and quantitative characterization. The methodology used by this program can be useful especially for investigations concerning Industrial Medicine, which intend to control the occupational risk due to environmental exposure, not only to perform an early diagnosis (secondary prevention), but also to control the temporal evolution of the disease, by comparing significant data in a reproducible way. ⋯ This fact confirms that the sequential approach used by Hepascore provides the same outcomes obtained by performing all tests in the entire population under study, allowing a saving of 57% of the total cost spent for the traditional evaluation. The sequential approach proposed by Hepascore could be employed in all the clinical settings in which an evaluation of liver functional state is required, both in presence of environmental risk factors and in the case of a programme for the optimization of the population's food habits.

Occupational exposure to high concentrations of anaesthetic gases can cause neurobehavioral effects in operating room personnel. The measures taken to reduce waste gas exposures, including the installation of active scavenging devices and airconditioning systems, are not effective, so that the NIOSH recommendations for maximum exposure are currently unattainable in practice. ⋯ Low-flow anaesthesia appears to be effective in reducing waste gas exposure: lower flows produced lower values and protect the integrity of neurobehavioral functions.

This article aims to discuss the influence that the application of the recent discoveries in genomics will have on the theory and practice of industrial toxicology in developed post-industrial countries. It is stressed that the recent advances in toxicogenomics can be integrated into the existing wealth of knowledge on the toxic properties of industrial chemicals to improve the efficacy of prevention of toxicological risk. ⋯ A closer integration between industrial toxicology and state-of-the-art molecular genetics derived from the recent sequencing of the human genome is the way to overcome the limitations described. In particular, the individual subjects in the examined populations can be classified with regard to some genetically controlled characters relevant to the biotransformation of xenobiotics and to DNA repair and the statistical analysis of data can be performed on more homogeneous subpopulations, in order to decrease inter-individual variability of biochemical and physiological response. This in turn increases the predictive power of the biological markers, both of dose and effect, and improves the efficacy of prevention, e.g., by highlighting oversensitive subpopulations or lifestyles which can increase the risk of occupational and environmental disease.

Low-dose exposures to mixtures of substances have received increasing interest and they involve many different occupational and environmental situations. The presence in the population (working and general) of groups of susceptible individuals is an important public health issue that poses new challenges to science and society. ⋯ The challenge in this field for the coming years appears to be not the analytical but the medical and ethical implications.

Rhizarthrosis of the hand secondary to job-related static-dynamic stress is a rare occupational condition characterised by secondary osteoarthrosis. ⋯ In the case of workers over 50 years of age whose jobs have the characteristics described here, Finkelstein's test should be performed on occasion of occupational health surveillance to screen for the arising of the disease.
