Abstract
OBJECTIVES We examined the association between travellers' characteristics, compliance with pre-travel recommendations and health problems. METHODS Volunteer travellers were enrolled and data collected using a questionnaire between 30-60 days after returning home. We analyzed the associations through bivariate and multivariate models. RESULTS Of the 468 enrolled travelers, 68% consumed raw food and 81% food containing milk and/or eggs. 32% consumed street vendor food and 30% drinks containing ice. 24% used the recommended mechanical prophylaxis measures. 46% got sick during and/or after travel (gastrointestinal symptoms most frequently). Factors predisposing to health problems were female gender, youth/middle age, intermediate travel duration and profession. The American continent and staying in hostels and tents were significantly associated with febrile illness. Street vendor food was significantly associated with skin reactions. CONCLUSIONS Adherence to behavioral recommendations remains low. Travellers must be informed of health risks during and after travel.

Abstract
Abstract
Introduction
Invasive Meningococcal Disease (IMD) is one of the most severe vaccine-preventable disease, with high fatality rate and severe sequelae in up to 20% of survivors. MenB, MenC and MenACWY vaccines are available in Italy, but recommendations vary among Italian regions in terms of type of vaccines and targeted age groups. The aim of the study is to describe epidemiology of IMDs in order to provide the best vaccination strategy.
Methods
IMDs surveillance data in the period 2011-2017 from the Italian National Health Institute were explored. Excel was used to present trend analysis, stratifying by age and serogroups.
Results
In Italy, during the period 2011-2017, IMDs overall incidence increased from 0.25 cases/100,000 inhabitants in 2011 to 0.33 in 2017. Most cases after 2013 were caused by non-B serogroups (52%, 52%, 66%, 64%, 59% from 2013 to 2017). Although incidence is highest in 1 years old children, the number of cases is highest in the age range 25-64. The number of cases in this age-range had a steady increase after 2013 (36 cases in 2011, 79 in 2017), with serogroups C, W and Y present in more than 65% of cases in 25+ age ranges after 2012.
Conclusions
IMD is a rare but severe vaccine-preventable disease. The key role of public health is to monitor disease serogroups, trends and outbreaks and strengthen methodological evidence-based tools for decision-making processes, public health policies, planning of healthcare services and intervention measures, including immunization. The increase in incidence shown in the period 2011-2017 in Italy, although probably due to better surveillance, highlighted the high circulation also of non-B serogroups and the importance of the disease in the adult population. Based on our analysis we believe that anti-meningococcal vaccination plan in Italy should include the highest number of preventable serogroups and be aimed to the whole population through a multicohort strategy, including boosters in children and in adults.
Key messages
Anti-meningococcal vaccination plan in Italy should include all the preventable serogroups and be aimed to the whole population with a multicohort strategy including boosters in children and in adults. The increase in incidence of IMD in the period 2011-2017 in Italy highlighted the high circulation also of non-B serogroups and the importance of the disease in the adult population.

Abstract
Background Human papillomavirus (HPV) infection is the main cause of cervical cancer and plays a relevant role in the development of genital warts and of the cancer of penis and anus, head/neck, oropharynx and genitourinary system. The aim of this study is the evaluation of hospitalizations due to HPV-related pathologies in 2001-12 in Italy. Methods The national hospital discharge forms were provided by the Ministry of Health. The HPV-related hospitalizations were identified using specific diagnostic codes, accordingly to the ICD-9-CM coding system. The proportion of hospitalizations of potentially HPV-related pathologies, obtained from the literature, was evaluated as well as the hospitalization rates (hr) and their trend over time. Results Uterine cervical cancer and CIN III accounted for 40% of hospitalizations (hr: 15.6/100 000 and 17.6/100 000, respectively). Head/neck and oropharynx pathologies accounted for 24.5% of cases (hr: 16/100 000 and 3.9/100 000, in males and females, respectively), followed by genital warts (17.3% of hospitalizations; hr: 7.5/100 000 in males and 8.52/100 000 in females), anal (8.1% of hospitalizations), genitourinary (7.7%) and penis cancers (2.2%). Conclusions The study, even if limited to the evaluation of hospitalizations, points out how HPV-related pathologies continue to be a relevant public health issue in Italy with a high impact on population.

Abstract
INTRODUCTION The appropriate use of antibiotics is a global priority in order to avoid antibiotic resistance. Up to 50% of antibiotics usage in hospital is inappropriate (e.g. prolonged surgical prophylaxis, "defensive medicine" approach). In 2015, at the Ferrara University Hospital, an antimicrobial stewardship intervention to reduce antimicrobial prescription at the time of hospital discharge in patients at risk of surgical site infection was implemented. This programme included: update meetings for health professionals, focused meetings for critical wards, reviews of some surgical prophylaxis protocols, recommendations to reduce broad-spectrum antimicrobials use, and planning of an audit. The purpose of this study has been to evaluate the effect of this antimicrobial stewardship programme. METHODS To evaluate the effect of this intervention, a study has been carried out including inpatients in surveillance for surgical site infection who had surgery during the last quarter of 2014 (pre-intervention group; 461 patients) and of 2015 (post-intervention group; 532 patients). RESULTS The proportion of patients with prescription of at least one antimicrobial at discharge decreased from 33% to 24.4% (p = 0.002). The most prescribed categories of antimicrobials in both groups were the combination of penicillins with beta-lactamase inhibitors (with prescription rate reduced from 21.9% to 18%; p = 0.13) and fluoroquinolones (from 8.2% to 3.2%; p < 0.001). CONCLUSIONS This statistically significant reduction in antimicrobial prescription after the intervention was registered without a change in surgical site infections rate (from 3.5% to 3.2%; p = 0.08). Therefore, this intervention was effective in reducing the antimicrobial prescription at discharge, without affecting patients' safety.

Abstract
INTRODUCTION Hospital infections, or "healthcare associated infections" (HAI) represent the most common and serious complications of healthcare. Adoption of safe care practices able to prevent or control the transmission of infections, both in hospitals and in other healthcare settings is crucial. The aim of the study is to assess the awareness about the risk factors and the most effective measures of prevention of HAI in the University of Ferrara nursing school students, giving particular attention to the hand hygiene practices and the use of standard precautions. METHODS 339 students attending all the three years of course of the same academic year were enrolled. An anonymous questionnaire was administered in order to investigate the knowledge about three specific areas: infections associated with healthcare practices (HAI), standard precautions (SP) and hand hygiene (HH). RESULTS A sufficient level of knowledge by all the three groups of students was observed only in the SP area. A barely sufficient score was reached only by the third year students with regard to the proper HH. The level of knowledge about HAI was inadequate. CONCLUSIONS A periodically check of nursing students' knowledge would be advisable in order to fill any gaps, improve training, reduce HAI and increase prevention measures compliance.

Abstract
INTRODUCTION Healthcare associated infections (HAIs) and misuse of antimicrobials (AMs) represent a growing public health problem. The Point Prevalence Surveys (PPSs) find available information to be used for specific targeted interventions and evaluate their effects. The objective of this study was to estimate the prevalence of HAIs and AM use, to describe types of infections, causative pathogens and to compare data collected through three PPSs in Ferrara University Hospital (FUH), repeated in 3 different years (2011-2013). The population-based sample consists of all patients admitted to every acute care and rehabilitation Department in a single day. METHODS ECDC Protocol and Form for PPS of HAI and AM use, Version 4.2, July 2011. Risk factor analysis was performed using logistic regression. RESULTS 1,239 patients were observed. Overall, HAI prevalence was 9.6%; prevalence was higher in Intensive Care Units; urinary tract infections were the most common HAIs in all 3 surveys; E.coli was the most common pathogen; AM use prevalence was 51.1%; AMs most frequently administered were fluoroquinolones, combinations of penicillins and third-generation cephalosporins. According to the regression model, urinary catheter (OR: 2.5) and invasive respiratory device (OR: 2.3) are significantly associated risk factors for HAIs (p < 0.05). CONCLUSIONS PPSs are a sensitive and effective method of analysis. Yearly repetition is a useful way to maintain focus on the topic of HAIs and AM use, highlighting how changes in practices impact on the outcome of care and providing useful information to implement intervention programs targeted on specific issues.

Abstract
We evaluated the diagnostic performance of a genomic DNA amplification method for Bordetella pertussis and Bordetella parapertussis compared with culture isolation. Aliquots from B. pertussis and B. parapertussis cultures were added to sterile physiological saline or sterile distilled water to give bacterial suspensions of 108 cells/ml and serial dilutions were prepared. Suspensions in physiological saline were cultured on charcoal agar medium; bacterial growth was observed up to dilutions of 10−7. Suspensions in distilled water were subjected to DNA extraction and nested polymerase chain reaction (PCR) was performed on the extracts; the PCR was positive up to dilutions of 10−8 for B. pertussis and 10−9 for B. parapertussis. Since the efficacy of culture isolation, regarded as the standard for the detection of B. pertussis and B. parapertussis, declines after the first stage of pertussis or with prior vaccination or antibiotic therapy, PCR, although not yet standardized, may provide an alternative diagnostic tool.

Abstract
In this study of influenza vaccination, 37 human immunodeficiency virus (HIV)-1-seropositive patients were randomized to receive either a vaccine with a conventional subunit or one adjuvanted with MF59. Blood samples were collected at the time of vaccination, and then 30 and 180 days later, to evaluate immunogenicity, CD4+ T-lymphocyte count and HIV-1 RNA levels. Seroconversion rates against the three viral strains included in the vaccine ranged between 44% and 72% and 53% and 68% for the adjuvanted vaccine and the subunit vaccine, respectively. Other criteria of the European Medicines Evaluation Agency were also met. Vaccination was not associated with serious adverse events. Local and systemic effects were mild and of short duration. CD4+ T-lymphocyte counts and viraemia levels were not negatively affected by vaccination. These results confirmed the safety and immunogenicity of these currently available vaccines in HIV-1-seropositive patients, thus supporting the recommendation for influenza immunization in this high-risk category.

Abstract
AIM The aim of this paper was to use and evaluate the unplugged project, a school-based program of proven effectiveness aimed at the prevention of substance abuse based on social influence. METHODS This project was conducted during the school-year 2011/2012; it involved the Local Health Unit (LHU)'s personnel specifically and adequately formed and was addressed to teachers working in the three districts of the LHU4 Chiavarese. The courses involved teachers in three consecutive days and provided both theoretical inputs and practical exercises designed to enpower skills and to make the same effective. As a whole, 25 teachers of the secondary schools (public and private) of first and second level were trained. Following the training, 14 curricular courses have been launched and 286 students have been involved. RESULTS The teachers have mainly worked on personal and social components of their students, stimulating their critical assessment of standards and skills potentially transferable in everyday life. The benefits for students have been: establishment of the classroom, positive relationship with the teacher, empathy, decrease of conflicts, increased self-awareness and self-esteem, better school results. Besides, teachers benefit from increased respect, self-reliance and confidence, as well as acquisition of new skills. CONCLUSION Both the interest shown by teachers and the results achieved in classrooms have stimulated school leadership and personnel belonging to LHU4 Chiavarese to plan a new edition of the program the next autumn.

Abstract
Infection with human papillomavirus (HPV) is very common and is acquired by at least 80% of women in their lifetime. A variable percentage of infections, particularly those supported by high risk types, becomes persistent, triggering a process that can progress to the development of cervical cancer, at least in a proportion of cases. The epidemiologic evidence accumulated over the years indicates the high impact of oncogenic HPV on the world's population, particularly women, and supports the need for preventive intervention. The preventive approach was initially based on screening and has led to important results. In fact, secondary prevention based on screening has reduced cervical cancer mortality by over 80% in many industrialized countries. The availability of HPV vaccines with high efficacy and safety has provided an innovative preventive option that requires to be integrated with secondary prevention already implemented. In this context, based on current scientific evidence, the present monograph has as its aims: 1) the assessment of HPV spread in the world and in Italy; 2) the analysis of the epidemiological and clinical burden of HPV-related diseases in both sexes; and 3) the evaluation of primary and secondary prevention strategies against HPV-related diseases and in particular against uterine cervical cancer.

Abstract
INTRODUCTION Estimate the efficacy of oral anticholeric vaccine Dukoral in subjects travelling to high-risk areas for traveler's diarrhoea and cholera. METHODS The study involved subjects of both genders who planned to travel to high-risk areas for traveler's diarrhoea and cholera. Immunization with oral anticholeric vaccine Dukoral was offered to each one of them. Upon returning, all the participants in the study were asked to complete a self-administered questionnaire consisting of 40 close-ended questions mainly concerning: personal and health data, characteristics (length, destination, reason) of the travel, onset of gastrointestinal symptoms, data relating to the assumption of anticholeric vaccine and possible adverse reactions. RESULTS 296 questionnaires have been collected. Mean age was 38.2 years (55.4% males and 44.6% females). Mean travel length was 22.2 days. Reasons for the travel: 66.8% tourism and 33.2% work-cooperation. Most frequent destination was Africa (48.1%), followed by Asia (32.1%) and central South-America (17.8%). 199 subjects (67.2%) properly executed vaccination with Dukoral. The diarrhoea affected 14.1% of vaccinated subjects and 20.6% of non vaccinated ones. The following cohorts showed statistically significant differences in incidence of diarrhoea: <35 years old age (13.7% vs. 27.1%), travel for work-cooperation (14.1% vs. 35%) and travel length >28 days (12.1% vs. 40%). No serious adverse events were reported following vaccination. DISCUSSION Oral Anticholeric vaccine proved to be effective and safe in preventing fecal-oral diseases in travelers exposed to high risk conditions.

Abstract
INTRODUCTION Sepsis is a major cause of significant morbidity and mortality in neutropenic patients. Blood culture remains the gold standard in the microbiological diagnosis of bacterial or fungal bloodstream infections, but it has clear limits of rapidity and sensitivity. The objective of the study was to compare the real-time polymerase chain reaction (RT-PCR) with automated blood cultures (BC) method in detection in whole blood of pathogens in febrile neutropenic patients with hematological malignancies. METHODS A total of 166 consecutive febrile neutropenic patients were enrolled. Blood samples for cultures and SeptiFast testing were obtained at the onset of fever, before the implementation of empirical antibiotic therapy. RESULTS Forty (24.1%) samples out of the 166 blood samples tested, were positive by at least one method. Twenty-three (13.9%) samples were positive by blood culture and 38 (22.9%) by multiplex real-time PCR. The analysis of concordance evidenced a low correlation between the two methods (n = 21; 52.5%), mainly due to samples found negative by culture but positive with the Septi-Fast assay. Sensitivity, specificity, and positive and negative predictive values of RT-PCR were 91.3%, 88.1%, 55.3%, and 98.4%, respectively, compared with BC. DISCUSSION Multiplex real-time PCR assay improved detection of the most bacteria associated with febrile neutropenia episodes. Further studies are needed to assess the real advantages and clinical benefits that molecular biology tests can add in diagnosis of sepsis.

Abstract
UNLABELLED INTRODUCTION. The screening programmes are very challenging from the ethical perspective, and their impact in terms of morbidity and mortality make secondary colorectal cancer prevention a valuable public health intervention. METHODS The target population people aged 50-69 years receive an invitation card with a test-tube for the fecal occult blood test (FOBT) and an immunochemical test is used for fecal occult blood. Subjects positive to FOBT are invited to perform a gastroenterologic examination and a full colonoscopy. RESULTS In the firt round of screening, 100% of the target population has been invited with an adhesion rate of 41.3%. A total of 1739 FOBT-positive subjects have been invited to the second level of the screening. 1429 of them have performed the gastroenterologic examination (83.9%). To date 956 full colonoscopies have been completed and the rate of subjects affected by carcinoma, malignant polyp and advanced adenoma has been equal to 23.5%. DISCUSSION Thanks to the reminders already sent, an increasing compliance has been registered with an increased rate of subjects with a low schooling that have performed a FOBT test. With the aim to optimize all the operative aspects of the screening programme it is already ongoing a set of meetings between health workers of Local Health Unit 4 and General Practioners.

Abstract
The aim of the present study is to analyze the methodological and technical aspects of Health Technology Assessment (HTA) as a tool for the clinical and economic impact of vaccine interventions, describe and comment the main studies at the national level, with a particular focus on HPV vaccination. The work was conducted in 3 phases: a) revision of the scientific literature, strictly linked to methodologies adopted in different studies on economic evaluations on HPV vaccines and analysis of Guidelines for building models for the economic assessment; b) analysis of the peculiarities and critical elements of economic evaluations in the field of vaccinology, from the clinical and epidemiological point of view, as well as the recognition of lack of knowledge on HPV infection dynamics; c) a comparative analysis of the two italian studies and of the results coming from them. Many differences between studies were found. Nevertheless, there is a general agreement on the economic profile of HPV vaccination for adolescent girls, if compared with the actual practice on the prevention of cervical carcinoma (pap-test screening). All the models showed a significant impact in terms of reduction of the incidence of cervical carcinoma and related mortality, in the long run, as well as a reduction of pre-cancer lesions and abnormal Pap tests. HTA approach has been recently recognized as a tool for decision making in vaccinology, and its methodologies and procedures are currently debated by public health experts. There is a strong need to continue the work in improving the model techniques of economic evaluations concerning HPV vaccination, as well as the adoption of homogeneous methods and standards, with the aim of helping the decision process in the field of Public Health.

Abstract
The surveillance and monitoring of rotavirus (RV)-related diseases, preferably through the establishment of sentinel surveillance sites, are essential for assessing the need for vaccination and the projected results of the vaccine in terms of reducing the burden of disease. The objective of the present study was to compare RV strains isolated in Northern (Ferrara) and Southern (Galatina-LE) Italy. During 2007-2008, 115 RV-positive stool samples were collected from children with diarrhea admitted to the hospitals of Ferrara and Galatina. The specimens were genotyped for VP7 (G-type) and VP4 (P-type) gene by reverse transcription (RT) and multiplex polymerase chain reaction (PCR). A subset of 21 RV strains was randomly selected and characterized by sequence analysis of the VP7 genes. In total, seven G/P combinations (G1P[8], G2P[4], G4P[8], G9P[8], G2P[8], G1P[9], and G2P[10]) were identified. Phylogenetic comparison of the VP7 encoding gene of selected strains showed that there was similarity among RV strains circulating in Northern and Southern Italy. The observation of nucleotide sequence diversity contributes to a better understanding of RV spreading and helps to characterize the various antigenic shifts that could have an impact on vaccine effectiveness.

Abstract
We report an increase in the incidence of measles in a population with consistently high and improving immunisation coverage in Ferrara province, northern Italy. During the first six months of 2010, 19 cases were confirmed, 10 of which were hospitalised. General practitioners, paediatricians and local healthcare authorities were alerted about the outbreak and asked to notify all suspected cases. We need to further increase immunisation coverage and to maintain and implement the monitoring system.

Abstract
INTRODUCTION Exposure to biological agents is the most common occupational risk for nursing staff. This study verified changes in attitudes and knowledge occurred in the nursing students after the first year of degree. METHODS The survey was conducted in academic year 2006/07 among the students of the Professional Nursing Course at University of Ferrara (Italy) using a structured questionnaire. Students were 85 at the beginning and 80 at the end of the courses. RESULTS The rate of subjects using gloves for intramuscular injections and fingertip puncture was unsatisfactory. A high percentage of students performed recap of needles. The use of gloves in case of washing of surgical instruments was high. The compliance in the use of gloves in handling test tubes remained low. Only 2/3 of the students washes their hands coming in ward. Incorrect attitudes have been observed in changing or wearing gloves. The students considered vaccination against hepatitis-B necessary, vaccination against flu unnecessary. A high percentage of students had not performed any prophylaxis for tuberculosis. DISCUSSION Students intend the use of gloves mainly to perform self-protection. The concept of self-protection is contradicted by the large percentage of students that recap used needles. A significant percentage of students have not yet gained the critical thinking necessary to consider the importance of universal precautions as a means not only of self-protection but also of prevention of hospital infections. CONCLUSIONS Students consider the basic standard measures for the control of infectious diseases only like self-protection and not to prevent hospital infections.

Abstract
Humoral and cell-mediated immunity (CMI) against B. pertussis was assessed in a sample of adolescent, adult and senior subjects distributed in five different geographical areas in Italy. Most (99.1%) subjects had IgG anti-pertussis toxin (PT) antibodies exceeding the minimum detection level [> or = 2 ELISA units (EU)/ml]. There were no significant differences between the genders; 6.2% samples recorded titres > or = 100 EU/ml. CMI was positive [stimulation index (SI) > or = 5] against PT in 39.0% of all samples. This study suggests that B. pertussis continues to circulate in age groups that have been previously considered to be uninvolved in the circulation of this pathogen and that adolescent and adult pertussis boosters may be of value in these populations. Nevertheless, over the last 10 years, large increases in vaccination coverage rates have contributed to reduce the spread of the aetiological agent, especially in the immunized population.

Abstract
Varicella is an infectious disease caused by a virus of the herpes virus family (VZV) affecting predominantly the pediatric age. Varicella is considered a mild disease, but in some cases, mainly in immunocompromised subjects, it can evolve towards complicated cases, even fatal. In immunocompetent subjects, however, serious complications can also arise, such as cutaneous bacterial superinfections, pneumonia, conjunctivitis or corneal infections and central nervous system (CNS) complications. The rate of hospitalization, even in developed countries, is high. Due to the epidemiological relevance of varicella, the availability of a live, attenuated, safe and effective vaccine, has prompted an international debate on the opportunity of extensive infant varicella vaccination, that could be overcome by the introduction of the combined tetravalent vaccines against measles, mumps, rubella and varicella (MMRV). Priorix Tetra, a new quadrivalent MMRV vaccine produced by GlaxoSmithKline, has demonstrated high immunogenicity, comparable to that of the separate vaccines (Priorix and Varilrix) in addition to a favorable tolerability and safety profile. This review summarizes the epidemiology of measles, mumps, rubella and varicella in Italy, encompassing the rationale for the introduction of varicella vaccination and describes the immunological, clinical and safety profile of Priorix Tetra.

Abstract
In Italy, although vaccination has been recommended for a number of years, vaccination coverage for mumps is still sub-optimal. The objective of the present study was to evaluate the seroprevalence of mumps antibodies in the Italian population, stratified by age, gender and geographical area. The proportion of individuals positive for mumps antibodies remained stable in the age classes 0-11 months and 1 year (25.4% and 30.8%, respectively) and showed a continuous increase after the second year of life. The percentage of susceptible individuals was higher than 20% in persons 2-14 years of age and exceeded 10% in persons 15-39 years of age. No statistically significant differences were observed by gender or geographical area. Comparison between these results and the data obtained from a 1996 survey showed a statistically significant increase in seroprevalence in the age class 2-4 years. No changes were observed in the other age-groups. The results of this study confirm that the efforts made in recent years to improve vaccination coverage within the second year of life should be strengthened.

Abstract
The objective of this study was to evaluate and compare both the safety and tolerability and the humoral and cell-mediated immune responses for two influenza virus subunit vaccines, one with MF59 adjuvant (Fluad) and one without an adjuvant (Agrippal), in healthy and in human immunodeficiency virus type 1 (HIV-1)-infected adult individuals. To achieve this aim, an open, randomized, comparative clinical trial was performed during the 2005-2006 season. A total of 256 subjects were enrolled to receive one dose of vaccine intramuscularly. Blood samples were taken at the time of vaccination and at 1 and 3 months postvaccination. A good humoral antibody response was detected for both vaccines, meeting all the criteria of the Committee for Medical Products for Human Use. After Beyer's correction for prevaccination status, Fluad exhibited better immunogenicity than Agrippal, as shown from the analysis of the geometric mean titers, with significant differences for some virus strains; however, no definitive conclusions on the clinical significance of such results can be drawn, because the method used to estimate antibody response is currently nonstandard for influenza virus vaccines. Significant induction of an antigen-specific CD4+ T-lymphocyte proliferative response was detected at all time points after immunization, for both the vaccines, among HIV-1-seronegative subjects. This was different from what was observed for HIV-1-infected individuals. In this group, significance was not reached at 30 days postvaccination (T30) for those immunized with Agrippal. Also when data were compared between treatment groups, a clear difference in the response at T30 was observed in favor of Fluad (P = 0.0002). The safety profiles of both vaccines were excellent. For HIV-1-infected individuals, no significant changes either in viremia or in the CD4+ cell count were observed at any time point. The results showed good safety and immunogenicity for both vaccines under study for both uninfected and HIV-1-infected adults, confirming current recommendations for immunization of this high-risk category.

Abstract
The European sero-epidemiology network (ESEN2) aims to standardise serological surveillance of varicella zoster virus (VZV) in 11 participant countries. In each country, serum banks were collected between 1996 and 2003 and tested for VZV antibodies. Assay results were standardised so that international comparisons could be made. Age-specific forces of infection were calculated for three age groups (<5, 5-9 and >or=10 years of age) and used to estimate the base reproduction number (R(0)) and the herd immunity threshold (H). Most VZV infection occurred in childhood, but there was a wide variation in transmissibility, with R(0) ranging from 16.9 in the Netherlands to 3.3 in Italy. Herd immunity thresholds varied from 70% in Italy to 94% in the Netherlands. There are substantial differences in VZV sero-epidemiology within the European region, which will need to be taken into account in designing national policies regarding VZV vaccination.

Abstract
In November 2003 the National Plan for the elimination of measles and congenital rubella was approved, with the aim of reducing and maintaining the incidence of congenital rubella syndrome (CRS) at less than 1 case per 100,000 live births by 2007. In order to describe the epidemiology of rubella in Italy, we conducted a serosurvey and evaluated incidence and vaccination coverage data available for the period 1998-2004. In the years considered, national mean coverage of measles-mumps-rubella vaccination within the second year of life, even though still below the 95% threshold, has progressively increased reaching 87%. In addition, previously existing differences in coverage among regions have diminished. In the same period the incidence of rubella has decreased, with a historic minimum of 461 cases notified in 2004. The cyclic pattern typical of rubella persists, but with a prolongation of the interepidemic period and an increased mean age of acquisition of the infection. Although the proportion of immune individuals has increased, the percentage of women of childbearing age susceptible to rubella remains high (11% in the 15-19 year age group and 8% in the 20-39 year age group) and CRS cases continue to occur. Despite the clear results achieved through the implementation of vaccination strategies in children within the second year of life, a continued strong public health commitment is required to increase the proportion of vaccinated individuals and absolute priority must be given to immunising women of childbearing age.

Abstract
Objective of this study was to provide data on hospitalizations for rotavirus gastroenteritis (RVGE) in Ferrara, Italy. The study was conducted analyzing the hospital discharge forms of all children admitted to the Pediatric Department of the University of Ferrara, Arcispedale Sant'Anna, from January 2001 through December 2005. The database was searched for all gastrointestinal diseases and in particular RVGE. During the period under study 3277 children, of which 2038 <60 months of age, were hospitalized; 247 children < 5 years old were admitted for acute gastroenteritis and 89 (4.4% of all and 36% of gastroenteritis-related hospitalizations) had rapid screening tests positive for rotavirus. A seasonal pattern was observed for RVGE with an increase in winter and early spring. The average length of hospital stay was 5.7 days. The median cost of each hospitalized case of RVGE ranged between 1417 and 1595 Euros. The present research confirms that rotavirus gastroenteritis represents an important cause of hospitalization in children and is responsible for significant costs for the Public Health Care System. An effective vaccination program could significantly reduce the incidence of hospitalization and the associated costs.

Abstract
Rotaviruses are the most common agents of diarrhoeal illness in infants and young children. Gastroenteritis caused by rotaviruses is also more likely to be associated with severe dehydration compared to other viral gastroenteritis. We determined the G-genotype of rotaviruses circulating in the Salento. During 2004, 144 stool samples were collected from subjects with a positive screening test and stored at -20 degrees C until confirmation could take place using molecular biology techniques. A reverse transcription-polymerase chain reaction (RT-PCR) assay for the amplification of gene VP7 of rotavirus was developed and used; G-genotype was determined by sequencing and phylogenetic analysis. A total of 101 stool samples were detected positive by RT-PCR and 35 were sequence analyzed and classified into G1, G2, G4, G9 and G12 type. The overall relative incidence of G-types in Salento is different to that of other developed countries. The most prevalent genotype was G2 while genotype G1 was present at low levels. It is also interesting to note the presence of G9 rotavirus, which is now recognized as the fifth globally important rotavirus genotype. In this study, therefore, we demonstrate the usefulness of a simple method for correctly determining the G genotypes circulating in a geographic region.

Abstract
The objective of this study is to evaluate how increasing MMR infant vaccination coverage in recent years has modified the epidemiology of rubella in Italy. A cross-sectional population-based seroprevalence study of rubella antibodies was conducted on 3094 sera, in 2004, and results were compared with data obtained by the same method in 1996. The overall proportion of rubella-seropositive individuals was found to be significantly higher in 2004 with respect to 1996 (84.6% vs. 77.4%). However, an increase in seropositivity was observed only in the 1-19 years age groups. Recent increases in childhood MMR vaccination coverage, therefore, have not had an impact on seroprevalence in women of childbearing age, over 5% of whom remain susceptible to rubella. Preconception screening and postpartum vaccination of susceptible women are fundamental if the WHO target of less than one case of congenital rubella syndrome per 100,000 live births is to be attained.

Abstract
BACKGROUND The objective of this study was to evaluate, within the Italian National Influenza Epidemiological and Virological Surveillance, the rate of vaccination coverage, the incidence of Influenza Like-Illness (ILI), the incidence of Acute Respiratory Illness (ARI), and to identify the virus strains circulating in Apulia from 1999 to 2003. METHODS Vaccination coverage rates were calculated based on the number of doses administered to individuals > 65 years of age. Every week, sentinel physicians reported ILI and ARI cases having occurred among their patients. Voluntary general practitioners (GPs) and paediatricians (Ps) collected oropharyngeal swab samples from patients suspected with ILI. Influenza viruses were isolated and identified by cell culture (MDCK cells) and RT-PCR. Virological surveillance was carried out by the ISS, in collaboration with a network of peripheral laboratories. RESULTS In Apulia, vaccination coverage progressively increased to 68.6% during the 2002-2003 season. The analysis of ILI cases showed higher incidence rates during the 1999-2000 and 2002-2003 seasons. ARI rates appeared to have a more constant trend. ILI and ARI incidence rates were higher in the 0-14 year age group. CONCLUSION The increase in vaccination coverage rates and implementation of the network of clinical, and epidemiological and virological surveillance are fundamental for the control and prevention of influenza.

Abstract
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.

Abstract
An investigation about N. meningitidis carriers was carried out in Apulia (Italy) among teen-agers. 85 healthy carriers were identified (1.4%): the 81.2% of isolates resulted polyagglutinable, 3.5% autoagglutinable and 1.2% were not classifiable with antisera. The other strains belonged to serogroup B (9.4%), W135 (2.3%), Y (1.2%) and 29E (1.2%). Some Authors report that non-groupable strains are usually isolated from healthy carriers pharynx. The most recent molecular methods permit to subdivide these bacteria in serotype and serosubtype by membrane protein antigens, too. So, today the only identification as serogroup is not able to study N. meningitidis epidemiology.

Abstract
We evaluated the stability and the bactericidal activity of a disinfectant containing sodium hypochlorite (Amiclor), which associates the buffer effect of the system sodium carbonate/sodium tetraborate to the stabilizing action of sodium chloride. The stability was determined evaluating the trend of the active chlorine title in various conservation conditions and comparing it with a product having only sodium chloride as stabilizing component. The bactericidal activity, instead, was evaluated by suspension and surface tests against Escherichia coli (ATCC 10536) and in relation to several variables, as product concentration, contact time, presence of interfering substances and water hardness. From the obtained data it is possible to affirm that Amiclor owns a greater stability as regards the traditional products stabilized only with sodium chloride. The activity tests have pointed out that the practical conditions affect the choice of the combination "product concentration/contact time" necessary to obtain an effective bactericidal activity. The activity of Amiclor is conditioned by the presence of proteins in the mixture or on the surface of reaction. This influence is not very clear in clean conditions while it considerably increases in dirty conditions. A decrease of bactericidal activity was observed when the product was diluted in hard water, mainly for contact times of 5 minutes or low product concentrations.

Abstract
A biomonitoring study using "Mytilus galloprovincialis" mussels was carried out, to estimate their possible employment as "natural indicators" of coastal bacterial pollution. The research was conducted from September 2001 to May 2002, twice in a month, near two coastal zones of Salento. We analysed both natural and cultivated mussels. The latter were placed in cages, after checking their starting level of microbiological pollution. The bacteriological analyses conducted simultaneously on mussels and their ambient water, were directed to the search of: total and faecal coliforms, faecal streptococci, Escherichia coli, Salmonella spp., Staphylococcus aureus and yeasts. In this preliminary study the mussels proved to be "sensitive indicators of faecal pollution", since they had an accumulation of the faecal indicators even if the water was not contaminated. Nevertheless a lower frequency in finding yeasts in the mussels (53.8%) in comparison with water (74.3%), the irregular presence of Salmonella spp. in water (3.75%) and its absence in bivalves, show the need of further studies, also through "in vitro" tests, in order to verify absorption/elimination kinetics of microorganisms.

Abstract
In order to know better the groundwater quality of Salento, chemical-physical and microbiological investigations were carried out on waters collected from 31 wells chosen after a preliminary study about the hydrogeologic features of the region. The analysis, conducted once in a month within the span of a year, pointed out a widespread contamination of faecal origin, which limits the employment (drinkable, irriguous) of groundwater because of possible health implications. The results of the chemical-physical analyses show how the groundwater of Salento is "contaminated" by sea water getting into the continent and which in some areas, also owing to excessive drawings, deteriorates its quality and compromises its irriguous use.

Abstract
Six countries (Denmark, England and Wales, France, Germany, Italy and The Netherlands) conducted large serological surveys for mumps, in the mid-1990s, as part of the European Sero-Epidemiology Network (ESEN). The assay results were standardized and related to the schedules and coverage of the immunization programmes and the reported incidence of mumps. Low incidence of disease and few susceptibles amongst adolescents and young adults was observed in countries with high mumps vaccine coverage (e.g. The Netherlands). High disease incidence and large proportions of mumps virus antibody negative samples in adolescent and young adult age groups was noted in countries with poor vaccine coverage (e.g. Italy). The build-up of susceptibles in older children and adolescents in England and Wales, France, the former West Germany and Italy indicate the possibility of further mumps outbreaks in secondary school environments. To control mumps in western Europe, current MMR immunization programmes will need to be strengthened in a number of countries. Sero-surveillance of mumps is an important component of disease control and its usefulness will be enhanced by the development of an international mumps standard.

Abstract
This study was carried out with the aim to investigate the presence of carriers of diphtheria bacillus in a sample of 1970 healthy children, 6-14 years aged, residing in eight Italian towns. Three non-toxigenic strains of Corynebacterium diphtheriae biotype mitis were isolated from as many healthy children. Molecular characterization by ribotyping showed close genetic relation of two of the wild strains with the C7(b) reference strain whereas one of the wild strains showed close genetic relation with two collection strains isolated in the same geographic area (Emilia-Romagna) from diphtheria patients in the seventy years. This supports the hypothesis of the persistence of some non toxigenic C. diphtheriae strains derived from ancient endemic strains under the selective pressure of mass immunization against diphtheria. The persistence of carriers of diphtheria bacilli, although non toxigenic, suggests that high levels of immunity must be maintained, not only in children, but also in adults by booster vaccination.

Abstract
Hepatitis E virus (HEV) is the causative agent of an enterically transmitted viral hepatitis associated with inadequate hygienic conditions. Hepatitis E is endemic in developing countries where it occurs both in sporadic and epidemic form. Outbreaks have been reported in different areas of the world. The aim of the present work was to assess the seroprevalence of HEV infection in the general population and in different risk groups in the area of Lecce. The presence of anti-HEV antibodies was ascertained by qualitative ELISA (Abbott HEV EIA) and Western Blot (Recomblot HEV IgG/IgM, Mikrogen). The prevalence of anti-HEV in the general population was 2.9% while in intravenous drug users, hemodialized patients and immigrants the seroprevalence rates were 0.7%, 4.3% and 15.3% respectively. Our data show a circulation of HEV at low level in the area of Lecce which is endemic for hepatitis A. Higher seroprevalence rates were found in hemodialized patients and remarkably in immigrants coming from endemic areas like Turkey.

Abstract
A serosurvey for measles, mumps and rubella was conducted in Italy; incidence based on statutory notifications over the last three decades was also calculated. In Italy the diseases followed an endemic-epidemic pattern, with an incidence peak every 2-4 years, and had a limited reduction of incidence attributable to childhood immunization. Lower notification rates were observed in the Southern regions. This is possibly related to greater under notification in the South and is confirmed by our seroprevalence data. Incidence of measles and rubella and proportion of cases among young adults increased significantly in the three decades considered, but not for mumps. Serological data confirmed that these infections are still very frequent in Italy, without significant geographic variation in the country. In the age groups 2-4 and 5-9 years the percentage of individuals still susceptible to each virus was higher than 30%. The proportion of susceptible subjects older than 15 years was similar for the three infections (6.1, 11.7 and 8.8% for measles, mumps and rubella, respectively). The low vaccine coverage for rubella and measles in Italy has so far only partially affected the occurrence of the diseases. No impact of mumps vaccination is visible. The average number of deaths, for each disease, has decreased during the three study periods. Today the priority in Italy is to halt the progressive increase of the mean age of acquisition of the three infections, to eliminate differences in coverage among regions and to conform to European standards. This will be achieved through a combination of increasing MMR vaccine coverage before 2 years of age, implementing vaccination campaigns for low seroprevalence age groups, and/or introducing a second dose of MMR, depending on the level of current MMR coverage.

Abstract
We conducted a study to assess the degree of varicella underreporting in Italy, and its distribution by age group and geographical area. Underreporting in individuals from 6 months to 20 years of age was computed as the ratio between the varicella seroprevalence in 1996 and the 1996 lifetime cumulative incidence based on statutory notifications. The degree of underreporting at the national level was 7.7 (95% CI 7.4-7.9); underreporting was greater in older age groups and in southern Italy. Quantification of underreporting can contribute to better understanding of the burden of varicella and to evaluating the potential impact of mass vaccination.

Abstract
BACKGROUND AND OBJECTIVES The development of electronic editions of scientific journals and the rapid spread of scientific information might modify the pattern the bibliographic citations, and thus the impact factor and quality of journals. We assessed changes in the impact factor over years of a number of journals and whether the presence of an electronic version of the journal was associated with the impact factor score. DESIGN AND METHODS This is a retrospective longitudinal study. The availability of journals (table of contents (TOC), abstracts, full text and free full text) on Internet, in years 1995-2000, was assessed between December 2000 and January 2001. The first 20 top-journals from 8 subject categories were included. Changes in impact factor over time and association with Internet availability were modeled. RESULTS Overall, 118/139 journals (85%) had their TOC on the Internet, of these 107 (77%) had abstracts, 97 (70%) had full text and 33 (24%) free full text. The median impact factor for all journals was 1.65, 2.08, 2.10, 2.21 and 2.35 for the years from 1995 to 1999, respectively. This increase was statistically significant, with differences among subject categories. The presence of TOC, abstracts and full text on the Internet was also significantly associated with higher impact factor, after accounting for time and subject category. INTERPRETATION AND CONCLUSIONS The impact factor has been used for assessing the quality of journals. We identified a new limitation of this indicator: the impact factor seems to be related to the amount of circulation of information through Internet. This could be a temporary limitation, associated with diffusion of journals on, and spread of Internet.

Abstract
We conducted a seroepidemiological study to evaluate the potential impact of mass varicella vaccination on the transmission of varicella-zoster virus (VZV) in Italy, where vaccination is not mandatory. We tested 3179 serum samples, collected from September 1996 to October 1997, for specific anti-VZV antibodies using a commercially available ELISA. The results confirmed that varicella typically involves children (82.1% seroprevalence among 10- to 14-year-olds) and that the mean age of acquiring the infection seems to be increasing. The results also revealed that southern Italy, compared to the rest of the country, has a greater circulation of VZV and an earlier age of acquisition. The potential impact of mass vaccination among 12- to 18-month-old children on the epidemiological trend of the infection must be carefully considered, in that failure to reach high levels of coverage could lead to an increase in the mean age of acquisition, which is already occurring in Italy.

Abstract
The European Regional Office of WHO has targeted measles for elimination from the region in 2007. Large national, age and sex stratified serological surveys of measles antibody were conducted in seven Western European countries from 1994-8 as part of the European Seroepidemiology Network. Three patterns were observed in the country-specific measles seroprofiles, ranging from (very) low susceptibility (four countries) to high susceptibility (one country). Susceptibility levels amongst 2-4-year-olds ranged from 2.9 to 29.8%, in 5-9-year-olds from 2.5 to 25% and 10-19-year-olds from 2.1% to 13.9%. A country's susceptibility profile was highly associated with vaccine coverage for the first dose. First dose coverage ranged from 91 to 97.5% for low susceptibility countries, 75 to 85% for intermediate susceptibility countries and 55% for the high susceptibility country. Only the high susceptibility country still reports epidemic measles. In low susceptibility countries, which have achieved or are very close to measles elimination, the priority will be to maintain high MMR vaccine coverage in all geopolitical units for both vaccine doses. In moderate susceptibility countries there is still some endemic transmission, but also risk of outbreaks as pools of susceptibles accumulate. In the high susceptibility country the priority will be to increase infant vaccine coverage and reduce regional variation in coverage levels.
