HEPATITIS B vaccines ,MEDICAL personnel ,VACCINATION - Abstract
Abstract: Background: In Italy, vaccination against hepatitis B virus infection was strongly recommended for healthcare workers since 1985. Update findings on vaccination coverage are lacking. Aim: To assess current vaccination coverage against hepatitis B in this job category. Methods: In 2006, 1632 healthcare workers randomly selected in 15 Italian public hospitals completed a self-administered precoded questionnaire. Results: The overall vaccination coverage was 85.3%, a figure higher than the 64.5% observed in 1996. Vaccine coverage showed a significant downtrend (p <0.01) from the Northern (93.1%) to the Southern (77.7%) areas. Logistic regression analysis showed that residence in the North (Odds ratio 4.2; 95% confidence interval 2.6–6.7) and youngest age (Odds ratio 4.5; 95% confidence interval 2.6–7.8), both were independent predictors of vaccine acceptance. Conclusions: Ten years apart, vaccine coverage has markedly increased, closely paralleling the downtrend in the incidence of acute B hepatitis among healthcare workers in Italy.

- Abstract
Objective: Multiple twin studies have demonstrated the heritability of anthropometric and metabolic traits. However, assessment of body composition parameters by bioimpedance analysis (BIA) has not been routinely performed in this setting., Design: A cross-sectional study., Setting: Study subjects were recruited and assessed at twin festivals or at major university hospitals in Italy, Hungary, and the United States to estimate the influence of genetic and environmental components on body composition parameters in a large, wide age range, international twin cohort by using bioelectrical impedance analysis., Subjects: 380 adult twin pairs (230 monozygotic and 150 dizygotic pairs; male:female ratio, 68:32; age years 49.1 ± 15.4; mean ± standard deviation; age range 18-82) were included in the analysis., Results: Heritability was calculated for weight (82%; 95% confidence interval [CI]: 78-85), waist and hip circumferences (74%; 95%CI: 68-79), body fat percentage (74%; 95%CI: 69-79), fat-free mass (74%; 95%CI: 69-79) and body mass index (79%; 95%CI: 74-83). The completely environmental model showed no impact of shared environmental effects on the variance, while unshared environmental effects were estimated as between 18% and 26%., Conclusions: BIA findings provide additional evidence to the heritability of anthropometric attributes related to obesity and indicate the practical value of this simple method in supporting efforts to prevent obesity-related adverse health events., (© 2014 Asian Oceanian Association for the Study of Obesity .

- Abstract
In a scenario of increasing life expectancy worldwide, it is mandatory to identify the characteristics of a healthy aging phenotype, including survival predictors, and to disentangle those related to environment/lifestyle versus those related to familiarity/genetics. To this aim we comprehensively characterised a cohort of 1,160 Italian subjects of 90 years and over (90+, mean age 93 years; age range 90-106 years) followed for 6 years survival, belonging to 552 sib-ships (familiar longevity) recruited (2005-2008) within the EU-funded GEHA project in three Italian geographic areas (Northern, Central and Southern Italy) different for urban/rural and socio-economical characteristics. On the whole, the following factors emerged as significant predictors of survival after 90 years of age: absence of cognitive impairment and physical disability, high hand grip strength scores and body mass index (BMI) values, "excellent/good" self-reported health, high haemoglobin and total cholesterol levels and low creatinine levels. These parameters, excluding BMI values, were also significantly associated within sib-ships, suggesting a strong familial/genetic component. Geographical micro-heterogeneity of survival predictors emerged, such as functional and physical status being more important in Southern than in Central and Northern Italy. In conclusion, we identified modifiable survival predictors related to specific domains, whose role and importance vary according to the geographic area considered and which can help in interpreting the genetic results obtained by the GEHA project, whose major aim is the comprehensive evaluation of phenotypic and genetic data.

- Abstract
Background: The fetal and infant life are periods of rapid development, characterized by high susceptibility to exposures. Birth cohorts provide unique opportunities to study early-life exposures in association with child development and health, as well as, with longer follow-up, the early life origin of adult diseases. Piccolipiù is an Italian birth cohort recently set up to investigate the effects of environmental exposures, parental conditions and social factors acting during pre-natal and early post-natal life on infant and child health and development. We describe here its main characteristics., Methods/design: Piccolipiù is a prospective cohort of expected 3000 newborns, who will be recruiting in six maternity units of five Italian cities (Florence, Rome, Trieste, Turin and Viareggio) since October 2011. Mothers are contacted during pregnancy or at delivery and are offered to participate in the study. Upon acceptance, their newborns are recruited at birth and followed up until at least 18 years of age. At recruitment, the mothers donate a blood sample and complete a baseline questionnaire. Umbilical cord blood, pieces of umbilical cord and heel blood spots are also collected. Postnatal follow-up currently occurs at 6, 12, and 24 months of age using on-line or postal self administered questionnaire; further questionnaires and medical examinations are envisaged. Questionnaires collect information on several factors, including mother's and/or child's environmental exposures, anthropometric measures, reproductive factors, diet, supplements, medical history, cognitive development, mental health and socioeconomic factors. Health promotion materials are also offered to parents., Discussion: Piccolipiù will broaden our understanding of the contribution of early-life factors to infant and child health and development. Several hypotheses on the developmental origins of health can be tested or piloted using the data collected from the Piccolipiù cohort. By pooling these data with those collected by other existing birth cohorts it will be possible to validate previous findings and to study rare exposures and outcomes.

- Abstract
Background: Hormone therapy (HT) in the menopause is still a tricky question among healthcare providers, women and mass media. Informing women about hormone replacement therapy was a Consensus Conference (CC) organized in 2008: the project Know the Menopause has been launched to shift out the results to women and healthcare providers and to assess the impact of the cc's statement., Methods: And Findings: The project, aimed at women aged 45-60 years, was developed in four Italian Regions: Lombardy, Tuscany, Lazio, Sicily, each with one Local Health Unit (LHU) as "intervention" and one as "control". Activities performed were: survey on the press; training courses for health professionals; educational materials for target populations; survey aimed at women, general practitioners (GPs), and gynaecologists; data analysis on HT drugs' prescription. Local activities were: training courses; public meetings; dissemination on mass media. About 3,700 health professionals were contacted and 1,800 participated in the project. About 146,500 printed leaflets on menopause were distributed to facilitate the dialogue among women and health care professionals. Training courses and educational cascade-process activities: participation ranged 25- 72% of GPs, 17-71% of gynaecologists, 14-78% of pharmacists, 34-85% of midwives., Survey: 1,281 women interviewed. More than 90% believed menopause was a normal phase in life. More than half did not receive information about menopause and therapies. HT prescription analysis: prevalence fell from 6% to 4% in five years. No differences in time trends before-after the intervention. Major limitations are: organizational difficulties met by LHU, too short time for some local activities., Conclusions: A huge amount of information was spread through health professionals and women. The issue of menopause was also used to discuss women's wellbeing. This project offered an opportunity to launch a multidisciplinary, multimodal approach to menopause looking not only at pharmacological aspects, but also at quality of life and information.

- Abstract
The health status of the oldest old, the fastest increasing population segment worldwide, progressively becomes more heterogeneous, and this peculiarity represents a major obstacle to their classification. We compared the effectiveness of four previously proposed criteria (Franceschi et al., 2000; Evert et al., 2003; Gondo et al., 2006; Andersen-Ranberg et al., 2001) in 1160 phenotypically fully characterized Italian siblings of 90 years of age and older (90+, mean age: 93 years; age range: 90-106 years) belonging to 552 sib-ships, recruited in Northern, Central and Southern Italy within the EU-funded project GEHA, followed for a six-year-survival. Main findings were: (i) "healthy" subjects varied within a large range, i.e. 5.2% (Gondo), 8.7% (Evert), 17.7% (Franceschi), and 28.5% (Andersen-Ranberg); (ii) Central Italy subjects showed better health than those from Northern and Southern Italy; (iii) mortality risk was correlated with health status independently of geographical areas; and (iv) 90+ males, although fewer in number, were healthier than females, but with no survival advantage. In conclusion, we identified a modified version of Andersen-Ranberg criteria, based on the concomitant assessment of two basic domains (cognitive, SMMSE; physical, ADL), called "Simple Model of Functional Status" (SMFS), as the most effective proxy to distinguish healthy from not-healthy subjects. This model showed that health status was correlated within sib-ships, suggesting a familial/genetic component., (Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
The Italian Twin Register has been in place for more than 10 years. Since its establishment, it has been focusing, on the one hand, on a continuous update of the existing information, and on the other hand, on new phenotypes and sample collection. Demographic data on about 140,000 twins have been updated using the municipality registries. The Italian Twin Register has been carrying out several new studies during the last few years. A birth cohort of twins, Multiple Births Cohort Study, has been started and the enrollment is ongoing. For this cohort, data on pregnancy and birth are collected, and periodical follow-ups are made. DNA is being collected for the twins and their parents. In the area of behavioral genetics, most efforts have been directed to psychological well being assessed with self-reported tools. Research on age-related traits continues with studies on arteriosclerosis development, early biomarkers in mild cognitive impairment, and the relation between lifestyle habits and mutagen sensitivity. The Italian Twin Register biobanking has grown in its size and in its know-how in terms of both technical issues and ethical procedures implementation. Furthermore, attitudes toward biobank-based research, together with willingness and motivation for donation, are being investigated. A valuable key resource for the Italian Twin Register is the possibility of linking twin data with disease registries. This approach has been yielding several important results, such as the recent study on the heritability of type 1 diabetes.

- Abstract
Objectives: Obesity and exposure to cardiovascular risk factors during adolescence may be associated with the development of atherosclerosis and cardiovascular diseases later in life. The objective of the study was to investigate whether any excess body weight, including moderate overweight, is associated with a more severe cardiovascular risk profile and signs of early atherosclerosis in a pediatric population., Patients and Methods: A cross-sectional study was conducted among 646 adolescents ages 11 to 13 years from several primary schools of Reggio Calabria, Italy. Body mass index, waist circumference, blood pressure, glucose, insulin, homeostatic model assessment of insulin resistance, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and C-reactive protein (CRP) were determined. All of the subjects underwent carotid ultrasonography for the measurement of intima-media thickness. Complete clinical data were available from 575 subjects., Results: Overweight was similarly frequent in boys and girls (31.2% vs 31.0%), whereas prevalence of obesity was higher in boys (18.4% vs 10.1%). Subjects with lower levels of HDL and higher levels of triglycerides, insulin, and CRP plasma were observed more frequently among overweight and obese subjects than nonoverweight. At multivariate analysis, HDL cholesterol, insulin, and CRP were associated (P < 0.05) with overweight and obesity in girls, whereas in boys, insulin and CRP were associated (P < 0.05) with overweight and obesity, and LDL cholesterol with obesity. The association between overweight or obesity and increased intima-media thickness, a sign of early atherosclerosis, was present in girls (P < 0.05) and was close to statistical significance in obese boys (P = 0.07)., Conclusions: Overweight and obese adolescents have a higher prevalence of cardiovascular risk factors and show signs of early atherosclerosis. In girls, in particular, overweight is sufficient to determine a more severe cardiovascular risk profile.

- Abstract
Objectives: Investigating women's knowledge, attitude and practice in relation to menopause and systemic hormone therapy (HT) through a sample survey implemented within the preliminary works for the Consensus Conference "Informing women on hormone replacement therapy" that took place in Turin in May 2008 [Available at www.partecipasalute.it. Last access 7/8/2008]., Methods: The survey involved representative samples of women 45-60 years from five Italian regions. Twenty trained interviewers distributed the questionnaires reaching participants at their homes. A total of 969 women were selected from electoral rolls. 720 of them completed the interview (74.3% response rate)., Results: Participants reported positive attitudes about menopause; more than 90% believed menopause is a normal phase in women's life and more than 40% stated it is a good experience for a woman. Nevertheless, more than half of the sample did not receive any information about menopause and possible therapies, and those who did, often rated it as poor and contrasting. Moreover, clinicians who prescribed HT reported advantages (94%) much more frequently than disadvantages (22%) and risks (39%) in relation to this treatment. Lack of knowledge was associated with women's low educational level and their no or scarce attitude to attend health services., Conclusions: More and qualified information should be provided to support women in making informed choices in relation to menopause and the use of systemic HT. Therefore, actions' should be carried out in order to strengthen the advisory role of clinicians and other sources of information, when taking care of women who may be using or thinking of using HT.

- Abstract
Since its start as a database of "possible twins", the Italian Twin Register has developed remarkably in terms of twin approach and recruitment, data-management tools, the cohorts enrolled, and the breadth of information gathered, making the Italian Twin Register a valuable resource for genetic epidemiological research. The Italian Twin Register is a random population of twins at both the national level and within targeted geographical areas or birth cohorts. Further, the Register is linked with disease records and has recently implemented a web-based method for volunteer twin recruitment specifically designed to promote the Register and to disseminate information on genetic epidemiology. To date, approximately 9000 twins have joined the Italian Twin Register, the majority of whom (approximately 70%) represent young adults aged 20 at time of enrollment. Although the total number of twins recruited to date is far below the expected figure initially predicted, the newly established standardized procedures guarantee an increase of around 2000 twins each year. Following the collaboration between the Italian Twin Register and the main Italian nonprofit association for blood donors, twin DNA sampling and storage has recently accelerated contributing to the large amount of phenotypic data collected. The Italian Twin Register is currently involved in both population and clinical based studies on various complex phenotypes and diseases, some conducted within large European consortia.

- Abstract
Background and Aims: We adopted the twin method to disentangle the genetic and environmental components of susceptibility to coeliac disease (CD). We estimated disease concordance rate by zygosity and HLA genotypes, discordance times, progression rates to disease, and heritability., Methods: We crosslinked the Italian Twin Registry with the membership lists of the Italian Coeliac Disease Association and recruited 23 monozygotic (MZ) and 50 dizygotic (DZ) twin pairs with at least one affected member. Zygosity was assigned by DNA fingerprinting, and HLA-DQ and DR alleles were genotyped. Disease status was ascertained by antiendomysial, anti-human tissue transglutaminase antibodies, and bowel biopsy., Results: Concordance was significantly higher in MZ (83.3% probandwise, 71.4% pairwise) than in DZ (16.7% probandwise, 9.1% pairwise) pairs. Concordance was not affected by sex or HLA genotype of the co-twin and being MZ was significantly associated with the occurrence of CD (Cox adjusted hazard ratio 14.3 (95% confidence interval 4.0-50.3)). In 90% of concordant pairs the discordance time was

- Abstract
Knowledge about the balance between heritable and nonheritable risk in multiple sclerosis (MS) is based on twin studies in high-prevalence areas. In a study that avoided ascertainment limitations and directly compared continental Italy (medium-prevalence) and Sardinia (high-prevalence), we ascertained 216 pairs from 34,549 patients. This gives a twinning rate of 0.62% among MS patients, significantly less than that of the general population. In continental Italy, probandwise concordance was 14.5% (95% confidence interval, 5.1-23.8) for monozygotic and 4.0% (95% confidence interval, 0.8-7.1) for dizygotic twins. Results in Sardinia resemble those in northern populations but in limited numbers. Monozygotic concordance was 22.2% (95% confidence interval, 0-49.3) probandwise, but no concordant dizygotic pairs were identified. A questionnaire on 80 items possibly related to disease cause was administered to 70 twin pairs, 135 sporadic patients, and 135 healthy volunteers. Variables positively (7) or negatively (2) associated with predisposition and concordance in twins largely overlapped and were mainly linked to infection. If compared with previous studies, our data demonstrate that penetrance in twins appears to correlate with MS prevalence. They highlight the relevance of nonheritable variables in Mediterranean areas. The apparent underrepresentation of MS among Italian twins draws attention to protective factors, shared by twins, that may influence susceptibility.

- Abstract
Serum biochemical liver tests (LTs) (ALT, AST, GGT) and platelet counts are often used to screen for chronic liver disease. Population-based data on abnormal LTs in Mediterranean areas are lacking. The prevalence and etiology of abnormal LTs were assessed from 2002 to 2003 in a 1 in 5 systematic random sample of the general population who were 12 years of age or older in Cittanova, a southern Italian town with 10,600 inhabitants. LTs, indices of metabolism, and markers of HBV and HCV infection were assayed and alcohol intake was recorded in the selected population. In virus-free individuals with abnormal LTs, LTs were retested, and upper abdominal echography and tests for other causes of liver damage were undertaken. Among the 1,645 individuals screened, the prevalence of anti-HCV was 6.5%; the prevalence was particularly high in individuals over 50 years of age. The corresponding prevalence for HBsAg was 0.8%. The overall prevalence of individuals with abnormal LTs was 12.7% (95% CI: 11.1-14.3). The probable cause of abnormal LTs was excessive alcohol in 45.6%, HCV in 18.6%, HBV in 1%, alcohol plus HCV and/or HBV in 8.8%, and rare diseases in 2%. In 24% of individuals with abnormal LTs, the probable cause was nonalcoholic fatty liver disease (NAFLD); in this subgroup, increased body weight, hypercholesterolemia, and hyperglycemia were common, and 63.3% of them had a bright liver at echography. In conclusion, in southern Italy, a Mediterranean area where dietary habits are different from those in industrialized areas, one eighth of the general population has abnormal LTs suggestive of possible liver damage; NAFLD appears to be emerging as a potentially important etiology of this presumed liver injury.

- Abstract
Reference values for 26 elements, namely Al, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Mn, Mo, Ni, Pb, Sb, Si, Sn, Sr, Tl, V, W, Zn and Zr are proposed in serum and blood of 110 healthy adults of the urban area of Rome. They were included in the study on the basis of strict criteria of eligibility and exclusion. With the exception of Ba, Bi, Co, Cr, Ni, Sb, Sn Tl in serum, and Bi, Hg, Si, V and W in whole blood, experimental data for each all the other analytes were found to approach a normal distribution. The estimated 5-95% references ranges (in ng ml(-1)) were reported. For several elements the reference ranges observed overlapped information available in the literature. Gender, age, body mass index, smoking habits and alcohol consume were used as grouping variables. Mutual associations were observed for several elements, as follows: Be, Ca, Co, Cr, Cu, Li, Mo, Pb and Zn with sex; Ca, Pb and Si with age (< and > 45 years); Co, Cr, Mo, Sb and Tl with body mass index; Cd and Pb with smoking habit; Cr and Pb with alcohol consume.

- Abstract
Goals: The aim of this work is to assess how the clinical features of celiac disease have changed in Italy after the widespread introduction of serologic tests in 1993., Study: Twenty Italian Clinical Centers collected information from 1982 until 2002 on 1968 patients older than 18 years diagnosed with celiac disease., Results: The results show that the incidence of atypical and silent cases of celiac disease has increased after the wider availability of serological test, which has allowed earlier diagnosis and treatment., Conclusions: This paper provides a view on the evolution of the clinical features of celiac disease in Italy over 2 decades. The relevance of the analysis is supported by the fact that Italy is one of the countries with the highest incidence of celiac disease. These findings underline the importance of a timely diagnosis of celiac disease.

- Abstract
Twins are a valuable resource for the study of complex traits. The twin method is substantially based on the comparison between correlations and concordance in monozygotic (MZ) and dizygotic (DZ) twins and allows several applications in biomedical and molecular genetic research. It allows either the qualitative and quantitative evaluation of the influences that genetic and environmental factors exert on phenotypes or the estimation of trait variability. Moreover, classical genetic linkage analysis is more powerful if performed in DZ twins. However, the twin method has some pitfalls, such as the necessity that collected samples be representative of both twin and general population. For this reason, over the last few years, a number of Countries have established population-based twin registers, which guarantee the maximum level of representation and, consequently, are of extreme value for epidemiological studies. Italy is also implementing a national twin register. The following is the description of the procedure that led to the establishment of the Italian Twin Registry.

- Abstract
Aims/hypothesis: The pathogenesis of permanent diabetes mellitus diagnosed early in life is heterogeneous and, in most cases, not known. We aimed at identifying markers differentiating between non-autoimmune and autoimmune diabetes., Methods: The clinical, genetic and epidemiological features of 111 diabetic patients (62 males) who received insulin within 12 months of life were studied., Results: The epidemic curve by age of diabetes onset revealed two subsets of patients at a cutoff of 180 days. In the group with diabetes onset before 180 days ("early onset" permanent diabetes) the analysis of HLA susceptibility heterodimers (available for 21 individuals) showed that 76% had a "protective" HLA genotype for Type I (insulin-dependent) diabetes mellitus as compared to 11.9% (5/42) of the later onset group. Accordingly, "early onset" children were less likely to have autoimmunity markers (4 out of 26 tested) than children with onset after 180 days (13 out 20 tested) (15.4% vs. 65.0%, p<0.01). Of note, 19 out of 20 (or the 95%) patients who were born on the island of Sardinia, an Italian region where the incidence of Type I diabetes is six times higher than continental Italy (33/100,000/year vs 5/100,000/year), were included in the later onset group (>180 days). Small-for-date birthweight, a possible sign of reduced foetal insulin secretion, was more common in the "early onset" group (OR=9.9, 95%-CI 2.6-38.6)., Conclusion/interpretation: These results, obtained in the largest population-based cohort of diabetic infants hitherto reported, suggest that "early onset" permanent diabetes cases differ from later onset cases and that most of them do not have an autoimmune pathogenesis.

- Abstract
Objectives: To evaluate the prevalence of and the risk factors for Helicobacter pylori in a population of medical and non-medical workers at a teaching hospital in Rome, Italy., Design: A cross-sectional study., Methods: From January to October 1998, 655 subjects (65% of the total population) underwent a 13C-urea breath test to assess H. pylori infection. Subjects completed a questionnaire concerning sociodemographic characteristics, work departments and history of some gastrointestinal symptoms. Differences in means and proportions were evaluated and independent predictors of H. pylori infection status were assessed by multiple logistic regression analysis., Results: Forty percent of the subjects were found to be H. pylori infected. The mean age of positive subjects was significantly higher than that of negative ones (38 +/- 14 versus 34 +/- 12 years; P < 0.01). No significant difference was found between males and females concerning the infection status (40.2% males versus 39.9% females). Lower years of father's education [odds ratio (OR), 3.1; 95% confidence interval (CI), 1.9-5.1] and age older than 35 years (OR, 2.0; 95% CI, 1.3-3.1) were the only independent predictors of the likelihood of H. pylori positivity. Prevalence of gastrointestinal symptoms was similar in infected and uninfected subjects. Physicians were significantly less infected than nurses and auxiliary personnel (26% versus 47% versus 55%, respectively); however, a loss of association was observed after adjustment by multiple logistic regression (OR, 1.8; 95% CI, 0.9-3.7). In all groups, some specific departments appear to be associated with a higher infection status., Conclusions: Among healthcare workers, H. pylori infection was associated with specific sociodemographic characteristics, such as age and level of father's education. The prevalence of H. pylori infection was not associated with different professional categories. However, some specific departments seem to increase infection risk.

- Abstract
In 1996-1997 data was collected and a Mantoux tuberculin test performed in 2882 Italian military recruits aged 18-23 years in order to establish the prevalence of tuberculin reactivity. In addition, the annual risk of infection, defined as the probability that a non-infected individual would be infected during the following year, was calculated. Of the 2882 recruits, 513 had received a BCG vaccination, the remaining 2369 had not. The overall prevalence of subjects with a tuberculin skin reaction size >5 mm (the cut-off point for positivity corresponding to the antimode in the reaction size frequency curve) was 6.1% (144/2369). The prevalence of skin reactivity increased with age but remained similar when related to area of residence, duration of father's school education and family size. The same general trend was observed if the standard pre-established cut-off point of 10 mm was used. In this case the overall prevalence of a positive skin reaction was 4% (95/2369). The annual risk of infection was 0.3% for a prevalence of tuberculin skin reactivity of 6.1% (cut-off point 5 mm) and 0.19% for a prevalence of 4% (cut-off point 10 mm). Analysis of the population sample vaccinated with BCG showed a lack of correlation between the positive reaction after vaccination reported retrospectively by the subject and the current skin reaction observed by the physician in this study (K = 0.254). Moreover, a significant difference was observed between the skin reaction in subjects vaccinated with BCG in 1993-1994 (average size 12.5 mm) and that of subjects vaccinated in 1995-1996 (average size 10.1 mm, P<0.01), probably as a consequence of mycobacteria circulating in the general population which act as a natural booster in people already vaccinated with BCG. A booster effect of tuberculin in Mantoux assays also cannot be excluded.

- Abstract
In 1997, prevalence of and risk factors for hepatitis A virus (HAV) infection were evaluated in 146 homosexual and 286 heterosexual men attending a Sexually Transmitted Disease (STD) Clinic in Rome, Italy. Total HAV antibody (anti-HAV) was detected in 60.3% of homosexuals and 62.2% of heterosexuals. After adjustment for the confounding effects of age, years of schooling, number of sexual partners, use of condoms, and history of STD, homosexuals were not found to be at increased risk of previous HAV exposure than heterosexuals (OR 1.1; 95% CI 0.7-1.9). Independent predictors of the likelihood of anti-HAV seropositivity among homosexuals and heterosexuals were: age older than 35 years and positive syphilis serology which is likely a proxy of lifestyles that increase the risk of faecal-oral infections. These findings do not support a higher risk in homosexual men but could suggest a role for the vaccination of susceptible patients attending STD clinics.

- Abstract
Acute promyelocytic leukaemia (APL) exhibits peculiar epidemiological, clinical, cytogenetic and molecular features, compared to the other acute myeloid leukaemias (AML). Data on epidemiology and occupational risk factors for APL desumed from the GIMEMA archive are reported and compared with those of the other AML. An exploratory case-case study was designed on AML patients from 56 haematology centres in Italy. Overall, 4296 patients older than 15 yr with a new diagnosis of acute leukaemia were recorded between July 1992 and July 1997. Of these, 335 were classified as APL, and 2894 as other AML. The median age of APL patients was 43 compared to 59 yr for the other AML (p < 0.00001). In order to identify peculiar risk factors for APL development, different parameters were compared in the 2 groups. After adjusting by age no significant differences were observed with regard to education, lifetime prevalence of cancer among siblings and previous diseases in the patient's history. Occupational exposure as a possible risk factor for APL showed no increased risk compared to other AML among farmers, builders and leather workers. A significant association was found in electricians (OR=4.4, 95% CI=2.0-9.7) and a weak association was found in wood workers (OR=3.2, 95% CI=0.8-10.8). The proportion of APL with respect to other AML was significantly higher in the north east of Italy compared to the rest of the country (OR=1.7, 95% CI=1.3-2.2). These data confirm the younger age of APL patients compared to the other AML. A possible role of electromagnetic fields is suggested by the higher risk of APL in electrical workers and in the more industrialized areas of the country.
