Six years of activity of the Italian vaccine portal "VaccinarSì": a web traffic evaluation using Google Analytics.

BACKGROUND: Despite the scientific consensus about vaccines safety and effectiveness, there is still a discrepancy between scientific evidence and perception by the general population. The "VaccinarSì" portal was created in 2013 by Italian specialists in Public Health to provide evidence-based information regarding vaccination. STUDY DESIGN: The purpose of this study was to analyse the web traffic on "VaccinarSì" platform during a six-year period (May 8, 2013-May 8, 2019). Moreover, we compared the first six-month with the last six-month period of the website activity, to identify potential areas of improvements. METHODS: This is a descriptive study using Google Analytics data. We collected data regarding the following: total number of sessions to the portal, total number of pages viewed, total number of users and the number of new visitors, geographical locations and demography of users as well as user access mode (type of device used and way of access). We also collected some data that were informative about the possibility to infer the level of visitors' engagement with the portal, such as thee number of returning users, bounce rate, number of pages visited per session and mean session duration. RESULTS: Throughout the relevant period, the portal has consistently increased its popularity, with a remarkable increment of monthly connections (ending up to more than 80,000/month) from all over Italy. Visitors were mainly female (71.1%), aged between 25 and 44 years (64.7%). Healthcare professionals were responsible for a considerable proportion of accesses (50.6%). The mobile has become the dominant device used to access the portal, accounting for 77.8% of total connection in the last six months. Similarly, in the last period, organic search accounted for 92% of all connections. Measles and MPR vaccine, as well as chickenpox and hexavalent vaccine, have remained the most appealing topics of interest among visitors over the years. The page that attracted more visitors over the six years was "real risks and benefits of vaccination", accounting for 5.67% of total sessions with a high mean duration spent of 05:08 minutes. CONCLUSION: During the six years of activity, overall, the level of users' engagement with the portal has dropped with an increased bounce rate and a lower average number of pages visited per session and a lower mean duration of each connection. The lowest engagement involved connections accessed through mobile devices. Results helped "Vaccinarsi" developers to speculate about future strategies to further increase the platform popularity and optimize visitors' engagement.

Screening for hepatitis B virus infection among refugees diagnosed with latent tuberculosis in an Italian community.

Background: Refugees are a growing population in the EU-27 area with specific health needs that are to be addressed in the most rapid and effective way at their arrival in the host country. Screening for Hepatitis B Virus infection is offered to specific categories and it could be useful and effective to extend its indications. The aim of this study was to define the epidemiological profile regarding Hepatitis B Virus infection in re-fugees hosted in the Asylum Seekers Centers of Verona (Italy), diagnosed with latent tuberculosis infection and eligible for chemoprophylaxis. Methods: We conducted a retrospective study in 715 refugees diagnosed with latent tuberculosis infection from January 1st, 2015 to December 31st, 2017. Screening for Hepatitis B Virus infection was offered to la-tent tuberculosis infection patients who were due to commence treatment. Subjects were tested for Hepatitis B surface Antigen and Hepatitis B core antigen total antibodies. None of the screened patients reported previous vaccination for hepatitis B. Results: Among the 715 refugees diagnosed with latent tuberculosis infection, 593 were eligible for treatment for latent tuberculosis infection. Of these, 211 (35.6%) accepted to be screened for Hepatitis B Virus infection. One hundred and ninety-five of the 211 (92.4%) came from African countries, and 16 (7.6%) from Asia; the majority (80.9%) were males. Median age was 23 years (95% CI 22-24). Of the 211, 58 individuals (27.5%) were Hepatitis B surface Antigen and Hepatitis B core antigen total antibodies positive; 74 (35.1%) were Hepatitis B surface Antigen negative and Hepatitis B core antigen total antibodies positive; and 79 (37.4%) were Hepatitis B surface Antigen and Hepatitis B core antigen total antibodies negative. Male gender and African origin were associated with a lower probability of being Hepatitis B surface Antigen- and Hepatitis B core antigen total antibodies-negative. Conclusions: Screening for Hepatitis B Virus is of paramount importance not only for the control and prevention of infection, but also in terms of long-term healthcare issues. Making screening more systematic can have an important impact on public health, while always considering cost-effectiveness and promotion of awareness among ethnic groups in order to gain their compliance to treatment/vaccination.

Active TB screening among homeless people attending soup kitchens in Verona (Italy).

Background: The hard-to-reach populations, including the homeless, are particularly vulnerable to the development of active tuberculosis. According to the World Health Organization, tuberculosis rates among the homeless in industrialized Countries are up to 20 times higher if compared with the general popula-tion, representing a relevant public health problem. The aim of our study was to describe the results of an active tuberculosis screening applied in order to find out suspected active TB cases among the homeless in Verona. Methods: As part of a partnership between the non-profit association Medici per la Pace and one of the Local Health Units of Veneto Region (ULSS 9 Scaligera) in 2018, a tuberculosis screening, based on thoracic radiographs, was offered to the homeless guests of two Verona's soup kitchens. Results: The studied population included 139 people, and three cases of suspected active tuberculosis, all in males, were observed. Among these, two received a diagnostic confirmation of active tuberculosis (a prevalence of 1.44% - CI: 0,17 - 5,1). Moreover, radiographic patterns of tuberculosis aftermaths were found in six additional subjects. Conclusions: Interventions specifically dedicated to hard-to-reach populations, can be useful in identifying tuberculosis active cases and controlling the disease in low tuberculosis burden countries. In particular, the active research of subjects, the screening carried out with mobile X-ray, and also the constant caring of the patients with active disease, could be the right method to keep under control this relevant public health problem.

Influenza vaccination and absenteeism among healthy working adults: a cost-benefit analysis.

BACKGROUND: Seasonal influenza is a highly contagious infection that might lead to serious clinical complications and incurs a conspicuous socio-economic impact. Influenza vaccination is currently recommended only for specific groups of healthy adults (such as healthcare workers) even though it was demonstrated to be effective in reducing absenteeism and decreased workers' productivity during flu epidemic period. The main purpose of this study is to analyse the extent of absences due to illness following a voluntary flu immunization program among the Komatsu Italia Manufacturing company's personnel during the flu season 2017-2018. Secondly, we aimed at performing a cost-benefit analysis of the vaccination campaign from the company's perspective. STUDY DESIGN: This is an observational cohort study conducted during the period between the 14th week of 2017 and the 13th week of 2018 (from 03/04/2017 to 01/04/2018). The study population was the personnel of Komatsu Italia Manufacturing S.p.A. on duty during the study period. METHODS: For each subject the following data were collected: sex, date of birth, professional profile, seasonal influenza immunization status and sick-leave days. Sick-leave days were compared among the influenza epidemic period and the previous one between vaccinated and unvaccinated and any difference in days of absence was considered to be caused by seasonal influenza. RESULTS: Out of 408 employees, 60 (14.7%) accepted the voluntary influenza vaccination. In multivariate analysis (logistic model) an age ≥ 50 years was the only predictor for vaccination acceptance (ORM 3.11 p<0.001). During the flu period, the monthly mean of sick-leave days per employee was significantly lower among the vaccinated than the unvaccinated, respectively of 0.328 days/person vs 0.752 days/person (p = 0.022). Unvaccinated employees reported a higher average of sick-leave days during the flu period compared to the previous non-influenza period (0.752 days/month/person vs 0.337 days/month/person p <0.001). The monthly mean cost for sickness absences per employee was significantly higher for an unvaccinated subject compared to one vaccinated, respectively € 129.00 and € 54.00 (p = 0.028). The overall net saving estimated was € 314.00 per person vaccinated. CONCLUSIONS: Influenza vaccination proved to be an extraordinary preventive tool and a cost-effective intervention. However, influenza immunization seems to be unappealing among healthy adults and higher flu vaccination coverages could be achieved through educational interventions possibly addressing young employees who showed little interest in vaccination. Finally, among health promotion interventions, companies should point out the importance of flu vaccination both for the individual wellbeing and the company environment.

The Prevalence of patients with panic attacks (PAs) and panic disorder (PD) visiting Emergency Departments of the Verona Hospital.

BACKGROUND: Panic Attacks (PAs) and Panic Disorder (PD) represent a heavy burden not only because of the difficulty in distinguishing them from other pathologies and in treating them appropriately but also because of their impact on public health worldwide. In Europe, PD constitutes one of the five most common mental disorders adversely affecting quality of life. STUDY DESIGN: The aim of this study is to evaluate the period prevalence of visits to the Emergency Departments of the University Hospital of Verona (North East of Italy) over the period between 2012-2016 because of symptoms of PAs or PD in order to quantify the burden of the disorder. METHODS: This study was carried out by retrospectively collecting data from the medical records of all the patients assessed at the Emergency Departments (EDs) of the Verona Hospital because of symptoms of PAs or PD over a 5-year period (1 January 2012 - 31 December 2016). The search words used in reviewing the medical records registered in the hospital discharge reports from the Gynecological, Pediatric and General Medicine Emergency Departments were: "Anxiety" and/or "Panic". A multiple logistic regression model was also created to evaluate the predictors of ED visits for PAs or PD over the period that was investigated. RESULTS: The study identified 3,771 cases of PAs or PD; 62.3% were females and 37.7% were males. The female-to-male ratio was 1.7:1. The mean age was 44 years (46 for the females and 41 for the males). The majority of the patients fell into two age categories: 30 to 39 (20.6%) and 40 to 49 (23.8%). The proportion of visits to the EDs for PAs or PD was approximately 20% per year, with an average of approximately 754 patients visiting the EDs every year. The period prevalence of accesses for PAs or PD over the five year period studied in the mean resident population (1.4%) and the mean visits to the EDs (2.5%) were calculated. Study results showed that the majority of the patients (80.9%) were referred to their general practitioner (GP) at the end of the assessment protocol at the EDs. According to the regression logistic model, the following variables were significant (p<0.05) risk factors for PAs or PD: being female vs. male (OR 1.899; 95% CI 1.785-2.020), being Italian vs. Foreigner (OR 1.292; 95% CI 1.174-1.421), having a white or green priority code at arrival (low urgency) vs. the other ones (OR 1.195; 95% CI 1.100-1.297), and being aged ≤42 years old (OR 1.091; 95% CI 1.024-1.161). CONCLUSION: The role of the GP is crucial in the management of PD and PAs. Given the difficulty of implementing primary and secondary prevention programs for these conditions, public health officials should make every effort to promote tertiary prevention in order to reduce the burden of the ailment and societal cost.

Energy drink and ginseng consumption by Italian university students: a cross-sectional study.

INTRODUCTION: The consumption of energy drinks (ED) and ginseng by young people to enhance their mental and physical performance has become widespread. Reported side-effects of ED have raised doubts regarding their safety. This cross-sectional study investigates the phenomenon. METHODS: An anonymous questionnaire was administered to a representative sample of Verona university students. The resulting data were analyzed with Excel 2013, STATA 13 software. RESULTS: ED and ginseng consumption was reported by 38.6% and 37.4% of the students, respectively. More than 70% of ED and ginseng users were 18 to 22 years old. Excluding non-responders, ED consumers were mostly males (51.8% vs 33.0%), contrary to ginseng consumers (females 40.4% vs 30.9%). Being a working student was significantly positively associated both to EDs (OR 1.5) and ginseng use (OR 1.4). The most frequently reported academic and other reasons for ED use were: "to study longer" (47.5%), and "to socialize" (29.1%). The most often used combinations were ED containing alcohol (65.6%) and ginseng-coffee beverages (71.8%). CONCLUSIONS: The diffusion of ED and ginseng consumption warrants prevention and monitoring measures, and deserves further analysis.

Brain doping: stimulants use and misuse among a sample of Italian college students.

INTRODUCTION: The non-medical use of prescription stimulants (NMUPS) has become the subject of great interest for its diffusion among university students, who abuse these substances to cope with the increasing load of academic stress. NMUPS has been widely investigated in the U.S. due to its increasing trend; this behavior, however, has also been reported in Europe. The aim of this cross-sectional study was to examine stimulants misuse in a Northern Italian geographic area, identifying possible developments of the phenomenon in Italy. METHODS: To evaluate academic and extra-academic NMUPS (Methylphenidate and Amphetamines), an anonymous multiplechoice questionnaire was administrated to a sample of Bachelor's and Master's degrees students attending a University North East of Italy. Data elaboration and CI 95% were performed with Excel software 2013. Fisher's exact tests were performed using Graph- Pad INSTAT software. RESULTS: Data from 899 correctly completed questionnaires were analyzed in this study. 11.3% of students reported NMUPS, with an apparent greater use by students aged 18-22 years (73.5%) and without any statistically significant gender predominance. Fifty-seven point eight percent of students used stimulants at most five times in six months, and the most frequent academic and extra-academic reasons to use them were respectively to improve concentration while studying (51.0%) and sports performance (25.5%). NMUPS was higher among working students than nonworking ones (p < 0.05), suggesting a use of stimulants to cope with stress by the first ones. CONCLUSIONS: These exploratory and preliminary data suggest that NMUPS is quite relevant in Northern Italy, suggesting a need for preventive and monitoring measures, as well as future analysis via a longitudinal multicenter study.

Prevalence of acute alcohol intoxication in Borgo Trento Hospital Emergency Department (Verona).

INTRODUCTION: Alcohol is an important factor weighting towards global disease burden, premature death and Disability-Adjusted Life Years. This study examines the burden imposed on the Borgo Trento Verona Hospital Emergency Department (ED) Italy by patients with Acute Alcohol Intoxication (AAI). METHODS: A 6-year retrospective study was performed by reviewing medical records in all patients (≥ 16 years old) diagnosed with AAI. Clinical criteria for inclusion in the sample followed those defined in the "Alcohol Intoxication Symptoms" section of DSM-IV-TR. Ambiguous cases presenting traumas potentially related to AAI were confirmed positive using a Blood Alcohol Level (BAL) test before inclusion in the sample. Socio-demographic data, case history, timing of admission/discharge and outcome were collected for each patient. RESULTS: One thousand five hundred forty-seven patients (males:females = 6.6:1) were included in the study. With regard to marital status, the crude rate within the sample shows that single and married subjects have a significantly higher prevalence (p < 0.01). When demographic data of residents was taken into consideration, divorced/separated and single categories were significantly more represented (p < 0.05). The admissions appeared fairly constant throughout the week with a higher prevalence of patients aged between 25-55 years, and a significant peak of the youngest age class on weekends. Higher rates of admission were recorded during the late afternoon and night. The triage code of admission appeared uniformly distributed along the week, with the highest prevalence of green code (67.7%), followed by yellow one (25.8%). The analysis of clinical symptoms and BAL highlights that moderate clinical severity concerns almost 50%, and clinically critical severity the 6.6% of cases of access. Admissions rates of foreign patients resulted to be 3 times higher compared to those of natives when adjusted to demographic data. DISCUSSION: Social disadvantages such as foreign provenance and social difficulties as unemployment, low money intake, perception of loneliness, and dysfunction in family life were frequently identified in the sample. An exception was found within the youngest age group, where the AAI are mostly related to alcohol abuse during social outings over the weekend. EDs play a crucial role in helping patients with AAI, but prevention of alcohol abuse though implementation of social and sanitary health policies on all ages (but especially among the youngest) is essential.

Piercing and tatooing in high school students of Veneto region: prevalence and perception of infectious releated risk.

INTRODUCTION: Body piercing (P) and tattoo (T) is a growing social phenomenon over recent years. Nowadays in Italy little is known about the prevalence, the attitude, the medical and social consequences of these activities. The purpose of this study is to examine the prevalence distribution and the attitude towards P and T and the perception of the risk for infections, in a sample of high school students living in the four Provinces of the Veneto Region (Italy). METHODS: An anonymous, self administrate multiple-choice questionnaire about piercing and tattoo practices was distributed during the 2009-2010 academic year to a sample of randomly extracted grades to obtain information about sociodemographic characteristics, family educational level, personal attitude, prevalence and perception of the importance of the sanitary, technical and artistic competence of the operator. RESULTS: The correctly compiled questionnaires were 2712 (95.4%). Males and females were respectively 46.2% and 53.8% (mean age 17 +/- 1.7 years). The 20.2% and the 6.4% of all the students had already experienced respectively P and T and resulted "very interested" the 46.7% to P and the 57.4% to T. Esthetical motivations are the main ones referred to use body art. The most part of interviewed subjects (81.6%) think that it is possible to have an infection, but only about 50% of students reported to know specific information about transmission of HIV, Viral Hepatitis and skin infections. The parents' educational levels do not influence the perception of the risk of infection. The majority of interviewed subjects (88.0%) prefers to undergo body art practices in a qualified center. Only the 30% of students recur to a medical help to solve problem of infection. DISCUSSION: The piercing and tattoo prevalence rate in our study (P: 20.2% and T:6.4%) resulted similar to other Italian ones (range reported: P: 20.3-35.1%, T: 4.8-8.6%), showing an increasing trend with age. Since a high rate of interviewed students referred a substantial ignorance about the risk of transmission of body art related infectious diseases, it is suitable to promote as soon as possible among the youth educational interventions and counseling.

The impact of acute intoxications in a toxicological unit care in north east Italy.

Retrospective study in a toxicological unit care (TUC) performed to know the epidemiology of acute intoxication (AI) in Verona (Italy) during years 2008-2009. All data regarding patients with a diagnosis of certain/suspected AI were collected and evaluated: some demographic information, the characteristics of the agent involved, the pattern of exposure, the triage at the admission to TUC and the outcome. 244 cases were analyzed: 45.9% males and 54.9% females, mean age respectively 45.1 and 43.9 years. The monthly distribution of admitted patients resulted fairly constant, except from a light rising prevalence in autumn, with a majority of yellow (45.9%) and green (43.4%) triage code. The pattern of exposure resulted: ingestion (82.7% of cases; age peaks: 18-34 and 35-51 years old; mostly due to food (as mushrooms), drinks, detergents, soap, pharmaceutical, drugs of abuse, caustics substances), contact (10.2% of cases; age peak 18-51) and inhalation (6.9% of cases). In 17.2% of cases the poisoning exposure was intentional. In 63.5% the patients were sent to their general practitioners (45.5% of the yellow and 81.1% of the green coded patients) and in 22.1% of cases they were admitted to clinical rooms (44.6% of the yellow coded patients). In most cases the triage code assigned to the studied patients resulted yellow and green. Considering that the seriousness of the symptoms can appear after several hours from the exposure to toxic substances, a quick and specific intervention to obtain the best therapeutical effectiveness is suitable, in order to save lives or to avoid irremediable health damages.

National pathfinder survey on children's oral health in Italy: pattern and severity of caries disease in 4-year-olds.

This paper describes the dental health status of Italian 4-year-olds in 2004/2005 and analyzes the association between caries in preschool children and some background characteristics in children and parents. Caries was recorded according to WHO criteria. 5,538 subjects were examined. Information on the children's and their parents' social, behavioral, ethnic and demographic status was obtained through a series of closed questions. Bivariate analysis was performed to investigate the association between caries and background characteristics. The probability of being an extra zero for the dmfs index was estimated via the zero-inflated negative binomial regression model (ZINB). 78.4% (95% CI = 77.2-79.6) of the children were caries-free. The national mean dmfs index was 1.36 (95% CI = 1.15-1.57), ranging from 1.22 (95% CI = 1.03-1.42) in the Italian North-East to 1.73 (95% CI = 0.83-2.63) in the South section. Significant bivariate associations between caries experience and risk factors were observed for parents' nationality (not Italian vs. Italian: p < 0.001), parents' educational levels (low vs. high: p < 0.001), preterm birth (yes vs. no: p = 0.011), prolonged breastfeeding (13 months: p = 0.038) and early tooth eruption (<6 months as reference: p = 0.004). Multivariable analysis (ZINB) showed that children with a low caries risk level had a higher probability of being an extra zero; in particular, children from fathers with a high educational level showed a probability of being an extra zero of 0.22. The results suggest a need to plan preventive programs to reduce oral health disparities among Italian preschool children, based on educational intervention with parents and children concerning oral health and caries prevention.

Epidemiology of domestic injuries. A survey in an emergency department in North-East Italy.

INTRODUCTION: Home injuries (HI) represent a social and public health problem worldwide. In Italy, there are 1,300,000-1,700,000 admissions to Emergency Department (ED) for HI and 130,000 hospitalizations every year, but the data are incomplete and fragmentary. A study of the phenomenon was carried out in Emergency Department (ED) of Civil Hospital of Verona to evaluate prevalence, characteristics and possible preventive actions. METHODS: In 2007, 3120 admission for HI have been registered at the Eä of the Civil Hospital of Verona. The distribution was calculated in relation to sex, age, month, code of urgency, outcomes, type and location of trauma. RESULTS: Children in pre-school age, men between 30 and 40 years and women over 60 years are the population groups most at risk, with a fairly homogeneous incidence distribution. Both sexes have similar distributions up to 41-50 years followed by an increase in females and a decrease in males at higher age. The traumas are generally slight (49.8% white code and 42.1% green code) and the hospitalizations represent 5.8% of all recorded HI. The most frequent injuries are wounds/abrasions (28.7%), contusions/crushing (27.7%) and fractures/distortions/ dislocations. The most affected body parts are hands and wrists (25.9%). Head trauma is significantly more frequent in children and elderly people, fracture in elderly people, and burn in adult women and male children. Every year about 30% of the admissions to emergency departments are caused by HI. Even though 92% of the times the events aren't serious, the sanitary cost is consistent due to the elevate number of admissions. It is therefore important to do prevention through sanitary education and adequate building legislation.

Self-reported sleep disorders in secondary school students: an epidemiological and risk behavioural analysis.

PURPOSE: To estimate the prevalence of self-reported sleep disorders (SD), to examine associations among demographic characteristics and familiar factors with SD, between SD and daytime sleep-related disorders (DD) and between evening habits and SD. METHODS: An anonymous questionnaire was proposed to 1563 students (aged 14-21 years, mean age 16.5 +/- 1.5; 42.8% males, 57.2% females) attending all classes of two high schools in Verona (North-East of Italy). Data were analyzed by some personal and familial characteristics, by definition of three sleeper groups (non problem, occasional problem or problem-sleepers). Moreover SD were put in relation with DD and with some personal evening attitudes. RESULTS: The 75.5% of the subjects report at least one SD. Difficulty falling asleep is the most frequent SD. The DD concern 91.2% of the sample. Females are more involved than males in SD and DD. All SD result strongly associated with the referred DD, except for sleepiness. Sport is significantly correlated with a minor prevalence of SD. Smoking and studying appear to be associated with SD. CONCLUSIONS: Since SD in youth constitute an important Public Health matter with a severe social impact they would be accurately studied to offer youth appropriate counselling given the importance of lifestyle in determining good sleep.

Perception and knowledge of HPV-related and vaccine-related conditions among a large cohort of university students in Italy.

HPV is involved in cervical, anal, penile, vulvar and oropharyngeal cancers, as well as genital warts. It is important to investigate knowledge and attitudes among university students, considering in this age a shift in healthcare decision-making from parents to students themselves. The aim of this study was to estimate knowledge and perception of HPV in terms of potential shame for HPV-related conditions, trust in vaccine efficacy and worry for potential side effects. The study involved students (18-25 years old) from the Universities of Padua and Verona, Italy. Socio-demographic and behavioural characteristics were collected with a questionnaire (n = 9988). Female gender and older age were positively associated with higher knowledge. The adjusted logistic regression showed an association between the set of perceptions investigated and the vaccination status, while a direct connection with knowledge was not found. However, another adjusted linear regression showed that a good set of perceptions could be partially explained by a high level of knowledge. Perceptions seem to fill an intermediate position between the knowledge and the decision to get vaccinated. The potential shame deriving from asking for HPV-vaccination was not identified as a relevant barrier. Having received information from healthcare workers, family and school showed to be positively associated with the adhesion to the vaccination policy. This study identifies university students as a possible target for HPV vaccination and pinpoints specific areas that might be targeted as first to encourage vaccine uptake. Primary prevention together with screening programmes remains essential in further reducing the burden of HPV-related diseases.

Prevalence of alcohol and drugs in urine of patients involved in road accidents.

OBJECTIVE: Road injuries are the leading injury-related cause of death among people aged 15-44. A clear dose-effect relationship has been demonstrated for drug and alcohol use and road traffic accidents. The objective of our study was to estimate the prevalence of drug and/or alcohol use in subjects admitted for road traffic accidents to an Emergency Department. METHODS: In this study, conducted between January and April 2006, 100 patients of both sexes (age 18-65) examined after road traffic accidents were consecutively enrolled. A commercial rapid urine test was used to detect drugs by the Emergency Department staff The alcohol concentration was determined from a blood sample at the central laboratory. RESULTS: Most of the patients were drivers under 35 years of age. 67/100 road traffic accidents occurred at the weekend (Friday-Sunday), nearly 60% between 24:00-09:00 hrs; on non-weekend days about 80% of road traffic accidents were recorded between 14:00-24:00 hrs (p < 0.0001). With the alcoholemia test and urine test for drugs detection 43/100 patients showed a single or multiple positivity. Alcohol and drug presence is relevant during the weekend (37/43 cases), in contrast with non weekend (6/43 cases) [OR 3.04 (95% CI 1.43; 6.46)]. Alcohol was the most frequently detected abuse substance (72%), followed by benzodiazepines (42%), tetrahydrocannabinol (21%) and cocaine (14%). DISCUSSION: 43% of patients examined were under the influence of psychotropic substances (alcohol, drugs or both). The greater part of road traffic accidents in positive test patients occurred during the week-end, in particular during the late night/early morning hours, probably after recreational time. The high incidence of alcohol and/or drug abuse may have caused physical and/or psychological problems, therefore the high number of road traffic accidents, especially if taken in combination. CONCLUSION: The rapid urine test used cannot represent a diagnosis, and requires a confirmation test. It can be used for medical purposes as an easy and fast preliminary response which enables a faster diagnostic and therapeutic guideline, but it cannot be used for sanctions. Further studies are advisable with an increase of number of patients, in a wider temporal range, including control subjects, and using confirmation tests.

National Pathfinder survey of 12-year-old Children's Oral Health in Italy.

No recent data on the experience of caries among Italian 12-year-olds are available. In 2004, an epidemiological survey called 'National Pathfinder among Children's Oral Health in Italy' was promoted and carried out. This study reports the actual oral health status of Italian 12-year-olds according to gender, residence area and geographical distribution. Clinical examinations were carried out from March 2004 to April 2005, according to WHO criteria, and included dental caries (decay at the dentinal lesion level) and Community Periodontal Index (CPI). 5,342 children (2,670 males, 2,672 females) were examined by 7 ad hoc calibrated raters. Dental caries experience was found in 43.1% (95% CI 41.8-44.4%) of the study population. The mean DMFT score was 1.09 (95% CI 0.98-1.21). Significant differences (p < 0.05) were observed among geographical sections for DT, FT and DMFT. An inverse relationship was observed between mean DMFT and gross national product per capita (p < 0.001). Gingival bleeding was observed in 23.8% of children, while 28.7% had calculus. Significant differences in CPI scores among sections were found throughout the sample in both males and females (p < 0.001). Over the past two decades, mean DMFT fell from over 5 to its present level, halving every decade; consequently, the recorded level of dental caries has become aligned with that in other Western European countries. Nevertheless, differences in DMFT values remain between children from different socioeconomic backgrounds.

Immunity to poliovirus among children and the elderly in north-east Italy.

INTRODUCTION: Italy and Europe were declared polio-free in June 2002, but increasing migration, even from undeveloped countries where polio still exists, may lead to a come-back of circulating poliovirus (PV) and infection in previously polio-free areas. It is consequently advisable to continue to monitor the immunity of the population in polio-free areas. The aim of this study was to assess the current prevalence of neutralizing antibodies in recently-immunized children and in elderly people who were never vaccinated. METHODS: Sera from 511 healthy subjects resident in the Veneto Region were examined to assay their antibody titer for PV 1, 2 and 3, using the microneutralization test. Data were analyzed by chi-squared test, Student's t-test and linear regression analysis, using EPI-Info 2000 supplied by the Centers for Disease Control and Prevention (Atlanta, GA, USA). RESULTS: Neutralizing antibodies in group A (231 subjects aged 1-17 years) showed significantly higher geometric mean titers (GMTs) than in group B (280 subjects aged 65-100 years) for all three PV serotypes (P < 0.001). Nobody simultaneously lacked neutralizing antibodies for all three serotypes. There were no difference between the two groups in terms of male/female GMTs for the three PV Antibodies decreased with time since vaccination, but the difference was only significant for PV 3. GMTs were lower in the elderly, with no significant difference among the three PV. DISCUSSION: The population examined showed a good level of protection against the three PV strains: both groups A (vaccinated) and B (naturally immunized) revealed a valid immunity to poliovirus. CONCLUSION: Immunization programs and immunity status population screening are still advisable until polio has been world-wide eradicated.

Relationship between pathological gambling, alcoholism and drug addiction.

The aim of this survey was to evaluate the distribution of pathological gamblers treated in an alcohol or drug addiction treatment program run by the Italian National Health Service providing assistance to alcohol and drug abusers in Venice (North east Italy) from September 1 to December 31, 2001. Each drug- or alcohol-dependent patient retained for treatment for at least one month was administrated an anonymous precoded questionnaire to collect personal and socio-demographic features. The South Oaks Gambling Screen (SOGS) was used to measure pathological gambling and the Symptom Checklist-90-Revised (SCL-90-R) to measure psychological distress levels and psychiatric symptoms. Among the 113 enrolled subjects we found a greater prevalence of pathological gamblers among drug users than among alcoholics and drug abusers were younger than alcoholics; moreover, there was a prevalence of single status, low schooling, and a low-medium income despite full-time occupation. Only pathological gamblers revealed a significant positive correlation with a family history of gambling and reached positive scores (>1.5) for some likely psychiatric symptoms. Abuse disorders and pathological gambling are frequently associated with multidependence personality traits. Preventing substance abuse may reduce the pathological gambling rates and better results can be obtained with educational campaigns beginning earlier in life.

Immunogenicity and Reactogenicity following Primary Immunisation with a Combined DTaP-HBV Vaccine and a Haemophilus influenzae Type B Vaccine Administered by Separate or Mixed Injection.

OBJECTIVES: The aim of this open, randomised, multicentre trial was to evaluate the immunogenicity and reactogenicity of the tetravalent diphtheria-tetanus-acellular pertussis-hepatitis B (DTaP-HBV) vaccine when given either as a mixed or as a separate concomitant injection with the Haemophilus influenzae type b (Hib) vaccine at 3, 5 and 11 months of age. METHODS: Antibody against diphtheria, tetanus, pertussis (ELISA), hepatitis B (radioimmunoassay) and Hib polyribosylribitol phosphate (PRP) [radiolabeled antigen binding assay] was determined. Solicited local and systemic adverse events were evaluated on the day of each vaccination and for three subsequent days. Follow-up of unsolicited and serious adverse events was conducted for 30 days following each vaccination. RESULTS: A total of 360 subjects were enrolled in the study. After completion of the three-dose vaccination course, seroprotective antibody concentrations against diphtheria, tetanus and hepatitis B, together with a pertussis vaccine response, were seen in almost all subjects with immunogenicity results (n = 336). All subjects had post-vaccination Hib anti-PRP antibody concentrations of at least 0.15 mug/mL, and 97.0% and 99.4%, respectively, of the subjects receiving a single or separate injections had Hib anti-PRP antibody concentrations >/=1.0 mug/mL. Addition of the Hib vaccine to the tetravalent DTaP-HBV vaccine did not increase the incidence of local or systemic reactions. CONCLUSIONS: Combination of DTaP-HBV and Hib vaccines in a single injection is safe, immunogenic and well tolerated, and thus has the potential to simplify the childhood immunisation schedule in Italy.

Factors influencing hospital infection control policies in Italian hospitals.

A study was undertaken to determine the resources available in Italian hospitals for the control of nosocomial infections and the factors favouring a successful approach. During January-May 2000 a questionnaire about infection control was sent to the hospital health director of all Italian National Health System hospitals treating acute patients and with more than 3500 admissions in 1999. An active programme was defined as a hospital infection control committee (HICC) meeting at least four times in 1999, the presence of a doctor with infection control responsibilities, a nurse employed in infection control and at least one surveillance activity and one infection control guideline issued or updated in the past two years. There was a response rate of 87.5% (463/529). Almost fifteen percent (69/463) of hospitals had an active programme for Infection Control and 76.2% (353/463) had a HICC. Seventy-one percent (330/463) of the hospitals had a hospital infection control physician and 53% (250/463) had infection control nurses. Fifty-two percent (242/463) reported at least one surveillance activity and 70.8% (328/463) had issued or updated at least one guidance document in the last two years. The presence of regional policies [odds ratio (OR) 8.7], operative groups (OR 4.2), at least one full-time nurse (OR 4.6) and a hospital annual plan which specified infection control (OR 2.1) were statistically associated with an active programme in the multivariate analysis.
