The present study aimed to describe the cognitive status of a group of HIV-positive asymptomatic intravenous drug users (IVDU) and changes which occurred over a 12-month follow-up period. Forty-two HIV positive IVDU were selected and matched for age, sex, educational level and pattern of drug abuse with 39 seronegative IVDU controls. Baseline and follow-up(More)
The aim of the Italian Multicentre Neuropsychological HIV Study is to assess the prevalence and natural history of cognitive deficit in intravenous drug users (i.v.DUs) during the asymptomatic phase of HIV infection. The study is currently being conducted in four centres (Napoli, Benevento, Verona and Pavia) whose catchment areas are characterized by(More)
A kinetic model describing the hepatic methylation of arsenite [As(III)] was developed on the basis of limited data from in vitro mechanistic studies. The model structure is as follows: sequential enzymic methylation of arsenite to its monomethylated (MMA) and dimethylated (DMA) products by first-order and Michaelis-Menten kinetics, respectively;(More)
Gambling has seen a significant increase in Italy in the last 10 years and has rapidly become a public health issue, and for these reasons the first National Helpline for Problem Gambling (GR-Helpline) has been established. The aims of this study are to describe the GR-Helpline users' characteristics and to compare the prevalence rates of the users with(More)

The study was performed both clinically and hemodynamically; patients were followed up for a long period (in one case up to 14 years). Although there were consistent differences in the rise and development of the(More)
In order to elucidate better the immunological effect of opioid abuse in the absence of HIV infection as a confounding factor, granulocyte function was investigated in three groups of HIV-negative subjects, including 20 active parenteral heroin abusers (H), 20 long-term methadone-maintained former opiate abusers (M) and 20 healthy controls (C). Chemotaxis(More)
The electrocardiogram of 27 patients with congestive cardiomyopathy (CMC), 15 with obstructive (CMO) and 13 with hypertrophic without obstruction (CMH) have been studied. Cardiac catheterization, angiography, coronary arteriography, and, in some cases, echocardiography, were performed. The study was carried out in an attempt to define certain patterns of(More)
