Migrant health: the Apulian model

Since the 1990s Puglia has been totally involved in the reception and assistance of refugees. The prevention of infectious diseases among migrants, especially those residing in communities, is an important concern for public health authorities, since infectious diseases eliminated in Europe may still be widespread in the migrants' countries of origin, and other diseases may have a higher incidence than in European countries. Thus immigrants may contribute to the burden and spread of infectious diseases

A study on the sexual and contraception behaviours of the pre-university students in Puglia (South-Italy)

Introduction. The aim of the present study is to determine attitude and associated factors towards the use of methods of protection/contraception. Methods. In August 2008, a study was carried out using a self-administered standardised anonymous questionnaire. It was administered to school-leavers who were attending a study course at Bari University. Results. The total number of questionnaires returned was 1091, the average age of the interviewed subjects was 19.6. Those declaring to have had sexual intercourse at least once was 88%. Of those sexually active, the average age at first intercourse was 16.8, and 75.2% stated that they had used some form of contraception on this occasion. The condom was the most popular method employed, followed by withdrawal and by contraceptive pills. Around 20% of the interviewees indicated that they used emergency post-coital contraception. Discussion. The study results emphasise the importance of an effective teaching of the aspects of sex and relationship education before puberty

How will the MMR universal mass vaccination change the epidemiologic pattern of mumps? A 2012 Italian serosurvey

To investigate the changes in the epidemiologic pattern of mumps, we carried out a serosurvey among young adults from Apulia, Italy. A convenience sample of 1,764 blood donors were enrolled in 2012: 93.4% (95% confidence interval, 92.1-94.5) showed a positive antimumps immunoglobulin G titre, geometric mean titer was 2.05. Results were consistent with previously published data on the immunogenicity of mumps vaccine but showed a lack of immunity (10% of people aged 18-26 years susceptible for mumps). Future research must be focused on the long-time immunogenicity of the mumps vaccine

An audit of TB prevention on Italian health care workers

Tuberculosis (TB) is considered an occupational disease in health care workers. The aim of this study is to asses the state of tuberculosis prevention among the personnel of the Vaccina- tion Services of the Puglia Region (Italy), who were given an interview-based standardised questionnaire. Of the 302 replies, TB screening had been undergone by 80.5%, whom 78.6% took advice by the occupational health physician. Of those who were negative to the PPD skin test, 60.6% had received BCG, whom 78% took vaccination advice by the occupational health physi- cian. In Italy, the procedures for the monitoring and prevention of tuberculosis are a consolidated practice for occupational health physicians

Clinical benefits of routine varicella vaccination for adults

Varicella is a highly contagious disease caused by varicella zoster virus. In children, it is generally a mild to moderate illness while it is often more severe in adults, with serious complications as dehydration, pneumonia, bleeding problems, infection or inflammation of the brain, secondary bacterial infections, sepsis, toxic shock syndrome, bone infections, joint infections and deaths. Some groups of adults are at major risk of complications, in particular immunocompromised persons as subjects with impaired humoral immunity and who is receiving systemic steroids, persons who live or work in environments in which transmission of varicella is likely, health-care personnel and pregnant women. After the introduction of Universal Mass Vaccination (UMV), the first mathematical models suggested that vaccination will lead to a shift in the average age at infection from children to adults with an increasing numbers of complicated forms, nevertheless new models predicted that, although an upward shift in the age at infection may occur, the overall morbidity due to varicella is likely to decrease. Current literature seems to suggest that for public health authorities the key action to prevent an increase of varicella incidence among adults is to achieve high vaccination coverage among babies and adolescents in countries who adopted UMV

Immunization coverage among splenectomized patients: Results of an ad hoc survey in Puglia Region (South of Italy)

Patients with anatomic or functional asplenia have a 10-50 times higher risk than general population to develop Overwhelming Post-Splenectomy Infection. Evidences are unanimous in recommending splenectomised patients to receive meningococcal, antipneumococcal and Haemophilus influenzae type B vaccinations according to a specific timing. In Italy there are no current data on the immunisation coverage in these patients. This study aims to investigate immunisation coverage in patients undergoing elective or urgent splenectomy for 2012-2013 in the 3 Apulian hospitals. The patients discharged with the code ICD-9-CM 41.5 - "Total splenectomy" were enrolled. The administration of vaccines was verified through consultation of medical records, archives of general practitioners and vaccination offices. In the study period, 166 subjects underwent splenectomy and none of them received vaccinations during hospitalization. 25 splenectomised patients (15.1%) received at least one of the recommended vaccinations. 21 patients (12.6%) received vaccine against Streptococcus pneumonia, 13 (7.8%) meningococcal vaccine, 10 patients (6%) Haemophilus influenzae type B vaccine. The low vaccination coverage could be due both to poor perception of the risk of infection and to a lack of knowledge on vaccinations by surgeons. For this reason it is necessary to draw up and share operational protocols that establish the administration of vaccines

Determinants of varicella breakthrough: Results of a 2012 case control study

This study aims to evaluate the determinants of breakthrough infection after one dose of varicella vaccine. We designed a retrospective case-control study. Breakthrough cases were children, aged 1-15, who presented varicella symptoms ≥ 42 days after the first dose of varicella vaccine (breakthrough). Controls were children, aged 1-15 years, who attended the same class (in a school or in a kindergarten) than the cases in the year of the breakthrough onset; they received a dose of varicella vaccine ≥ 42 days before the case rash onset and they did not develop varicella symptoms. We enrolled 45 cases and 135 controls. 40% of cases (n = 18; 95% CI = 25.4-54. 6) presented at least one risk factor; this proportion was 39.2% (95% CI = 30.9-47.6) among the controls (chi-square = 0.0078; P = 0.93). Time between vaccination and virus exposure was longer among cases. Logistic regression showed that breakthrough disease was associated with duration of time from vaccination

Communication about vaccinations in Italian websites: A quantitative analysis

Babies' parents and people who look for information about vaccination often visit anti-vaccine movement's websites, blogs by naturopathic physicians or natural and alternative medicine practitioners. The aim of this work is to provide a quantitative analysis on the type of information available to Italian people regarding vaccination and a quality analysis of websites retrieved through our searches. A quality score was created to evaluate the technical level of websites. A research was performed through Yahoo, Google, and MSN using the keywords "vaccine" and "vaccination," with the function "OR" in order to identify the most frequently used websites. The 2 keywords were input in Italian, and the first 15 pages retrieved by each search engine were analyzed. 149 websites were selected through this methodology. Fifty-three per cent of the websites belonged to associations, groups, or scientific companies, 32.2% (n = 48) consisted of a personal blog and 14.8% (n = 22) belonged to some of the National Health System offices. Among all analyzed websites, 15.4% (n = 23) came from anti-vaccine movement groups. 37.6% reported webmaster name, 67.8% webmaster e-mail, 28.6% indicated the date of the last update and 46.6% the author's name. The quality score for government sites was higher on average than anti-vaccine websites; although, government sites don't use Web 2.0 functions, as the forums.: National Health System institutions who have to promote vaccination cannot avoid investing in web communication because it cannot be managed by private efforts but must be the result of Public Health, private and scientific association, and social movement synergy

A nosocomial outbreak of 2009 pandemic influenza A(H1N1) in a paediatric oncology ward in Italy, October – November 2009

A nosocomial outbreak of 2009 pandemic influenza A(H1N1), with eight confirmed cases, occurred in a paediatric oncology ward in Italy, in October/November 2009. The fact that one case was infected despite being isolated and without contact to a symptomatic patient, hints towards potential transmission through a health care worker (HCW) and underlines the importance of vaccination of HCW who are involved in the care of critically ill patients

Serosurveillance of hepatitis A in a region which adopted the universal mass vaccination

Hepatitis A is a common infectious disease worldwide that was endemic in many regions of Southern Italy, such as Apulia region. After a large hepatitis A outbreak occurred between 1996 and 1997, in Apulia an active-free immunization program that was targeted to new-borns and adolescents was started. The aim of this study is to investigate the hepatitis A seroprevalence in the adult Apulian population 18 years after the immunization program introduction, in order to evaluate the risk of new epidemics onset.The study was carried out from May 2011 to June 2012 among blood donors from Department of Transfusion Medicine and Blood Bank of Policlinico General Hospital in Bari. Participants signed a written consent and filled out a questionnaire including items on demographic characteristics, risk factors, disease memory, and raw food consumption. Serum samples, collected from each patient, were tested for anti-HAV using the chemiluminescent microparticle immunoassay. Vaccination status against hepatitis A was checked on Regional Digital Immunization Registry (GIAVA).In total 1827 donors agreed to participate (77.7% male) with a mean age of 38.4 ± 11.7 years. However, 1172 (64.1%) donors were seropositive with no difference by sex. The highest proportion of seronegative subjects was in the 27 to 35 years age group. 91.8% of 1-dose vaccinated subjects (n = 190/207; 95%CI = 87.2-95.1) and 96.1% (n = 171/178; 95%CI = 92.1-98.1) of 2-doses vaccinated subjects were immune to the disease. Sensitivity of disease memory in unvaccinated subjects was 14.4% (95%CI = 12.2-16.7), specificity was 97.8% (95%CI = 96.3-98.8), positive predictive value was 91% (95%CI = 85.3-95), and negative predictive value was 42.6% (95%CI = 40-45.2). Raw seafood consumption in unvaccinated subjects was associated with the anti-HAV IgG positivity (OR = 2.1; 95%CI = 1.7-2.7; z = 7.4; P < 0.0001).The vaccination program seems to have changed the virus circulation pattern, with a higher seronegativity rate among subjects not included in the vaccination strategy: 67% of susceptible subjects were among younger people aged 27 to 35 years. Immunization program implementation with a catch-up strategy may be needed to avoid a possible increase of hepatitis A incidence and outbreaks in Apulia. Epidemiological surveillance should be continued and vaccination should actively be offer for free to all the cases contacts, in order to prevent new outbreaks onset
