QoL assessment is currently considered essential for clinical trials in HIV infection, as commonly used end-points (CD4 level, viral load, opportunistic diseases) are inadequate to catch the complexity of treatment outcomes. The World Health Organization has recently developed a standardized set of instruments to assess subjective quality of life (QoL) in different medical conditions, including HIV infection. Here we report evidence for the acceptability, reliability and validity of the Italian version of the WHOQOL-HIV. The Italian version of WHOQOL-HIV has been administered in a sample of 151 HIV-positive persons, consecutively attending the largest infectious diseases hospital in southern Italy. Mean time of administration and percentage of missing responses, Cronbach alpha, Pearson coefficient and oneway ANOVA were applied to assess, respectively, acceptability, reliability, convergent and disciminant validity, and sensitivity to change. Mean time of administration was 28 minutes; only 2 questionnaires showed more than 20% of missing responses. Cronbach alpha was above 0.70 in 22 of the 28 sections of the WHOQOL-HIV; it ranged between 0.53 and 0.68 in the remaining 6 sections. Each of the 7 QoL principal domains correlated with overall QoL at a significance level p < 0.001. Moreover, correlation between principal domains were always statistically significant (p < 0.01) with only two exceptions. Finally, mean scores in each QoL domain were in the expected direction (worse in AIDS patients as compared to asymptomatic and symptomatic persons). The Italian version of WHOQOL-HIV is a valid and reliable instrument to assess subjective QoL in HIV-positive persons. It seems potentially useful to assess patients' life satisfaction, and to calibrate standards of care in different stages of the infection.

The data reported in the present paper provide preliminary evidence of the reliability and validity of the ISSQoL questionnaire for the measurement of HRQoL in HIV-infected people. The direct involvement of HIV-positive people in all the phases of the project was a key aspect of our work.

To study the effects of a comprehensive, multifaceted intervention program to reduce fireworks-related injuries during the Italian New Year's holiday season, active surveillance was conducted in the 18 public emergency rooms of Naples, Italy, before and after implementation of the program. Preintervention data collected between December 24, 1992, and January 6, 1993, were compared with data collected during the same period in 1993-1994. The number of injuries decreased by 48% from 353 to 183, with the greatest declines seen among 10- to 12-year-olds. The broad-based intervention implemented during the 1993-1994 holiday season appears to have substantially reduced the number of injuries.

We carried out a telephone survey to assess willingness to participate in HIV vaccine trials. The survey was conducted by interviewing randomly selected callers to the Italian National AIDS Help line. The questionnaire consisted of four sections: demographic information, knowledge about HIV vaccines and vaccines in general, factors related to participation in HIV vaccine trials, and acceptability of a future HIV vaccine. Over 50% of the sample had adequate knowledge about HIV and vaccines. Among the individuals interviewed, 37% would volunteer for a vaccine trial; those reporting high-risk behaviours were more likely to volunteer. Of the participants, 83% would agree to be vaccinated with a highly effective vaccine, and 92% would pay for the vaccine. Although the limits of telephone surveys should not be neglected, the results of this survey are encouraging.
