To estimate the impact of intravenous drug use (IVDU) on mentality in the general population of young adults in Rome, Italy, the Population Attributable Risk (PAR) was calculated for the overall and cause-specific mortality in the 15–34 years age group. Relative risks were derived from a previous historical cohort study on mortality among 4200 intravenous drug users (IVDUs) in Rome, in which increased mortality from cardiovascular, respiratory, and gastrointestinal diseases as well as from violence, overdose and AIDS had been observed. The prevalence of the risk factor (i.e. the proportion of IVDUs) in the general population was estimated using the ‘multiplier formula’ and ‘capture-recapture’ methods. The proportion of all deaths attributable to IVDU in the 15–34 age group in the Roman population was 16% and 9% in males and females, respectively. The cause-specific attributable proportions were 66% for endocarditis and 37% for cirrhosis in males, and 36% for endocarditis and pneumonia in females. These findings further document the relevant health consequences of IVDU on the general population of a large metropolitan area.

Objectives: to evaluate the effectiveness of a large-scale, school-based, teacher-delivered campaign for the prevention of HIV infection. Methods: 46 junior and senior high schools in the Lazio Region of Italy were randomized to either an intervention or a control group. The corresponding study population consisted of 645 teachers and 3,866 students. The intervention followed the methods used in a large-scale, teacher-delivered campaign already implemented in the schools of the region. Questionnaires eliciting AIDS-related knowledge, attitudes and risk perceptions were administered to teachers and students in both study groups before and after the intervention. The increments in scores were analysed by a mixed model analysis of variance. Results: the average increment in the teachers' knowledge score was 4.18 points higher in the intervention group than in the control group (p

Overdose mortality is the major adverse health effect of drug injection. The potential determinants of overdose death are poorly understood; the aim of this study was to investigate risk factors for overdose mortality among intravenous drug users (IVDU). A cohort of 4200 IVDU attending methadone treatment centres in Rome during the period 1980-1988, was enrolled. Data were collected from clinical records. Vital status and cause of death were ascertained as of 31 December 1988. A matched case-control analysis within the cohort was performed to identify risk factors of death from overdose. All overdose deaths were included as cases and four controls, matched on year of birth and sex, were selected for each case from among the cohort members still alive at the time of death of the corresponding case. In all, 81 deaths from overdose were identified as cases and compared with 324 controls. A high risk of overdose death occurred among subjects who left treatment compared with those still in treatment (odds ratio [OR] = 3.55, 95% confidence interval [CI]: 1.82-6.90). The OR was particularly elevated in the first 12 months after drop-out compared with those retained in treatment (OR = 7.98, 95% CI: 3.40-18.73). The risk of overdose death was higher for unmarried compared with married people (OR = 2.48, 95% CI: 1.31-4.68); a higher risk of overdose death was also associated with lower educational status and younger age at first drug use, but such association was not statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)

The present estimates of the lung cancer risk for the general population due to radon exposure in dwellings are generally obtained by extrapolating the risk estimates derived from epidemiologic studies on miner cohorts. However, due to uncertainties related to this extrapolation, numerous case-control studies in Europe and North America were planned to estimate directly the risk in dwellings. Most of these studies are still underway and, thanks to their similar design and compatible protocols, it will be possible to perform a pooled analysis in order to improve statistical power. One of these projects is being conducted in the Lazio region of Italy. In this paper the main results of the studies already published are summarised, and the principal characteristics of the Italian study are outlined.

We investigated whether exposure to indoor [gamma]-radiation and radon might be associated with enough free radical formation to increase urinary concentrations of 8-hydroxydeoxyguanosine (8-OHdG), a sensitive marker of DNA damage, due to a hydroxyl radical attack at the C8 of guanine. Indoor radon and [gamma]-radiation levels were measured in 32 dwellings for 6 months by solid-state nuclear track detectors and thermoluminescent dosimeters, respectively. Urine samples for 8-OHdG determinations were obtained from 63 healthy adult subjects living in the measured dwellings. An overall tendency toward increasing levels of 8-OHdG with increasing levels of radon and [gamma]-radiation was seen in the females, presumably due to their estimated longer occupancy in the dwellings measured. Different models were considered for females, with the steepest slopes obtained for [gamma]-radiation with a coefficient of 0.500 (log nmol/l of 8-OHdG for each unit increase of [gamma]-radiation on a log scale) (p

Because of the variety of problems connected with the AIDS epidemic, there is an urgent need for qualified information and counselling. In June 1987, The Italian Ministry of Health established a hot-line, acting within the National AIDS Operational Centre. Through the analysis of more than 39,000 calls received during the first year of activity, a clear outline has been obtained of the emotional impact of the disease on Italian public opinion, and of the problems raised. 67% of callers belong to 20–39 age group; the male/female ratio is 2:1. Interesting correlations have been found between the content of the questions and the sex, age, and type of caller. The vast majority of questions concerning basic concepts and notions about HIV infections are asked by no-risk-related subjects. During the first year, the percentage of questions asked by subjects actually at risk increased, and the questions themselves have become more specific.

The most common complications in plastic surgery are tissue reactivity, infections, and wound dehiscence. In the literature, there are only a few studies with sample sizes large enough and methods of statistical analysis appropriate for evaluating the role of suture materials in inducing such complications. In the 1000 plastic surgery outpatients in this study, the association of different suture materials, individual patient characteristics, surgeon skill, and wound site and length with postoperative wound complications (i.e., tissue reactivity, infection rate, and wound dehiscence) were investigated. No substantial differences were found between the different suture materials and suturing techniques. A moderate increase in the risk of tissue reactivity for silk and polyglactin 910 and a protective effect of thinner internal sutures were observed. In multivariate analysis, such differences were not statistically significant. Male sex [odds ratio (OR), 1.7; 95 percent confidence interval (CI), 1.06 to 2.72] and older age (OR, 2.34; 95 percent CI, 1.36 to 4.05) were found to be the most important risk factors for tissue reactivity and infection rate (male sex: OR, 5.1; 95 percent CI, 1.7 to 15.9; older age: OR, 5.6; 95 percent CI, 1.9 to 16), whereas younger age was associated with an increased risk of dehiscence (OR, 3.06; 95 percent CI, 1.41 to 6.65). Wounds on the lower limbs showed a lower risk of tissue reactivity and wounds on the back a higher risk of dehiscence. Wound length was associated with the risk of tissue reactivity in one-layer sutures (OR, 2.92; 95 percent CI, 1.51 to 5.65). An increased risk of both tissue reactivity (OR, 1.53; 95 percent CI, 1.03 to 2.27) and dehiscence (OR, 2.44; 95 percent CI, 1.1 to 5.43) was observed for operations performed by less-experienced surgeons. Rather than factors related to suture materials and different surgical techniques, and with the exception of surgeon experience, general characteristics of the patients (i.e., sex and age) and of the wounds (i.e., length and site) seemed to be primarily responsible for local wound complications.

To examine factors associated with compliance with dermatologic treatment.Longitudinal study. Quality of life and psychological well-being were measured before the dermatologic visit with a self-completed questionnaire. Telephone interviews were performed 3 days and 4 weeks after the visit to evaluate patient satisfaction and medication adherence, respectively.Outpatient clinics of a large dermatologic hospital in Rome, Italy.A total of 1389 outpatients were contacted and 722 (52%) agreed to participate. Among them, 424 responded to the inclusion criteria and were enrolled in the study. Of these, 396 (93%) completed the telephone interviews.Self-reported compliance with dermatologic treatment.The dermatologists' prescriptions were not exactly followed by 44% of patients. In multiple logistic regression analysis, treatment adherence was strongly associated with complete satisfaction. Poor quality of life on the emotions scale (indicating mainly high levels of shame and embarrassment) was also associated with medication adherence. On the contrary, a strong negative association was observed between psychiatric morbidity and compliance.This is the first longitudinal study on dermatologic patients showing that dissatisfaction with care and psychiatric morbidity are significantly and independently associated with poor medication adherence. To improve medication adherence, particular attention should be dedicated to the physician's interpersonal skills, which emerged as a major component of patient satisfaction. Moreover, our results highlight the need for a timely identification and appropriate management of psychiatric disorders in everyday dermatologic practice.
