Abstract
OBJECTIVES This study aimed to assess the impact of the COVID-19 pandemic on national surveillance of viral hepatitis in Italy. STUDY DESIGN Interrupted time series analysis. METHODS Using an interrupted time series analysis with a customised AutoRegressive Integrated Moving Average model on hepatitis cases reported to the Integrated Epidemiological System of Acute Viral Hepatitis from 2006 to 2022, we examined trends in incidence, time to diagnosis and time to epidemiological investigations for hepatitis A, hepatitis B and hepatitis C. RESULTS The quarterly incidence of hepatitis B (-0.251, P = 0.05) and hepatitis C (-0.243, P = 0.003) significantly decreased with the onset of the pandemic. Surveillance times for hepatitis B (5.496, P < 0.001) and hepatitis C (35.723, P < 0.001), measured as days lost per quarter, significantly increased 12 and 24 months after the pandemic's start. This aligns with a notable rise in quarterly incidence at 36 months for both (0.032, P = 0.030 for hepatitis B; 0.040, P < 0.001 for hepatitis C). CONCLUSIONS The decrease in reported cases could be due to an increase in infection prevention control and containment measures put in place in a pandemic context. However, a delay in the initiation of epidemiological investigations was observed, which could lead to a further increase in incidence in the future.

Abstract
OBJECTIVE Coronary artery disease is one of the first causes of death in the Western world; for this reason, it is essential to identify new, systemic, non-invasive and low-cost cardiovascular risk markers. The acute coronary syndrome includes ST-Elevation Myocardial Infarction (STEMI) and Non-ST-Elevation Myocardial Infarction (NSTEMI), based on ECG findings. We aimed to evaluate Renal Resistive Index (RRI) as a marker of cardiovascular risk and assess the associations with other cardiovascular risk factors (metabolic indexes, mineral metabolism disorders and endothelial dysfunction and atherosclerosis markers) in STEMI and NSTEMI patients. PATIENTS AND METHODS Clinical, laboratory and instrumental examinations as metabolic and inflammation indexes, markers of atherosclerosis and endothelial dysfunction (renal function, mineral metabolism disorders, inflammation indexes, Intima Media Thickness (IMT), Ankle Brachial Pressure Index, Left Ventricular Mass Index, Relative Wall Thickness) were performed. RESULTS Eighty-one patients with STEMI and NSTEMI were enrolled. We showed a significant positive correlation between RRI and age (p<0.01), intact parathyroid hormone (p<0.01) and IMT (p<0.01), as well as a significant negative correlation between RRI and body surface area (BSA) (p=0.02), estimated Glomerular Filtration Rate (eGFR) (p<0.01), serum calcium (p<0.01) and 25-hydroxy-vitamin D (p=0.03). Moreover, we found a significant correlation between RRI and male patients (p<0.01), coronary artery disease history (CAD) (p=0.049), hypertension (p=0.025) and left ventricular eccentric hypertrophy (LVEH) (p=0.047). CONCLUSIONS Our study showed an association between RRI and the main traditional and non-traditional cardiovascular risk factors involved in atherosclerosis pathogenesis, such as age, BSA, hypertension, male sex, CAD history, mineral metabolism disorders and LVEH, in patients with preserved renal function. Moreover, we found a significant correlation between RRI and eGFR, suggesting that RRI could be useful in the evaluation of both renal function and progression of renal damage, even in an early stage with a conserved or only slightly reduced kidney function. We also showed a significant correlation with some markers of systemic atherosclerosis such as IMT and LVEH. For a more precise assessment of prognosis and cardiovascular risk in patients with high cardiovascular mortality, we suggest performing a systematic RRI evaluation, considering the non-invasive nature of the procedure, its reproducibility, easy execution, and low costs.

Abstract
This paper studies the temperature dependence of the electrical resistivity of low-cost commercial graphene-based strips, made from a mixture of epoxy and graphene nanoplatelets. An equivalent homogenous resistivity model is derived from the joint use of experimental data and simulation results obtained by means of a full three-dimensional (3D) numerical electrothermal model. Three different types of macroscopic strips (with surface dimensions of cm2) are analyzed, differing in their percentage of graphene nanoplatelets. The experimental results show a linear trend of resistivity in a wide temperature range (-60°C to +60°C), and a negative temperature coefficient . The derived analytical model of temperature-dependent resistivity follows the simple law commonly adopted for conventional conducting materials, such us copper. The model is then validated by using the graphene strips as heating elements by exploiting the Joule effect. These results suggest that such materials can be used as thermistors in sensing or heating applications.

Abstract
This paper deals with the fabrication, modeling and experimental characterization of a monitorable and renewable graphene-based pollution filter. The main goal is to demonstrate a method to monitor the status of such a filter in real time during its operating phases: pollutant adsorption, saturation, and regeneration. The filter is realized by a disk of pressed graphene nanoplatelets. This is a low-cost type of graphene which has recently drawn great interest due to its potential use in large scale industrial production. Here the nanomaterial is obtained through the exfoliation method assisted by microwave irradiation, by exploiting the thermal expansion of commercial intercalated graphite, according to a low-cost and ecologically friendly procedure. The filter is used here to adsorb acetonitrile, a toxic water-soluble organic compound that is present in some industrial solvents and paints. The monitoring method is based on the interpretation of the time variation of the electrical impedance measured during filter operation. There are two main results of the paper: Firstly, the graphene filter is shown to be effective in adsorbing the above pollutant, with the additional feature of being fully renewable: all the pollutant can be removed from the filter without the need of costly physical or chemical processes. Secondly, monitoring of the time-evolution of the electrical impedance allows efficient detection of the different phases of the filter life cycle: clean, polluted, saturated and regenerated. This feature is of potential interest since it enables the predictive maintenance of such filters.

Abstract
PURPOSE To investigate the association at baseline between plasma levels of selected vitamins and the presence and type of cataract in the participants in The Italian-American Trial of Nutritional Supplements and Age-related Cataract. METHODS At baseline, the participants (1020, 710 with "early cataract" and 310 with "no cataract," 55-75 years of age) received an ocular examination, photographic lens grading, and measurement of plasma levels of vitamins A, C, E, beta-carotene, and of red blood cell glutathione reductase activity. RESULTS In multiple logistic models adjusted for potential confounders, high vitamin C levels were associated with a protective effect on nuclear (N) [OR: 0.54; 95% CI: 0.30, 0.97] and posterior subcapsular (PSC) cataract (OR: 0.37; 95% CI: 0.15, 0.93). High vitamin E levels were associated with increased prevalence of cortical cataract (C) (OR: 1.99; 95% CI: 1.02-3.90), PSC (OR: 3.27; 95% CI: 1.34, 7.96) and of any cataract (OR: 1.86; 95% CI: 1.08, 3.18). CONCLUSIONS In agreement with some earlier studies, we found higher plasma levels of vitamin C to be associated with reduced prevalence of N and PSC cataracts. The finding of an increased prevalence of some types of cataract with higher levels of vitamin E was unexpected, has not been previously reported, and could be due to unadjusted confounding.

Abstract
PURPOSE To report the long-term outcome of patients with indirect traumatic optic neuropathy (TON) which showed useful vision for a short period after trauma. METHODS A cohort of 12 TON patients treated with steroids megadose immediately after trauma was followed every 6 months for an overall period of 5 years. Other than a full neuro-ophthalmologic examination, each visit included quantitative Goldmann perimetry and pattern reversal visual evoked potentials. The results of each examination were compared with the visual function at baseline. The main outcome measures were visual acuity and visual field. Data were analyzed using the Wilcoxon signed-rank test. A p value of less than 0.05 was considered statistically significant. RESULTS All patients showed a stable visual function 5 years after optic nerve trauma. There was no difference in visual acuity levels (p=0.65) and no visual field surface area between the visit at baseline and the last follow-up. However, a significant improvement in visual field extension (p=0.036) was observed after perimetry evaluation. CONCLUSIONS This cohort of patients clearly demonstrates that the residual visual function found in the short term after TON is maintained for at least 5 years. These findings add further important clinical information for patients with TON. Furthermore, these data may be helpful to better quantify morbidity related to optic nerve trauma and its permanent sequelae.

Abstract
We carried out a multicentre study on 2830 patients with chronic liver disease from 79 liver units (25 in northern, 24 in central and 30 in southern Italy) to evaluate naturally acquired immunity against hepatitis A virus (HAV) in relation to age, sex, geographical area of origin and entity of liver disease, and to define the strategy for specific vaccination. Antibody to HAV (anti-HAV) was detected in 1514 (53.5%) of the 2830 patients tested; the prevalence was 50.4% in males and 59.1% in females. Both in central and southern Italy the prevalence of anti-HAV positive subjects increased with increasing age from 43.3 and 44.7%, respectively, in the 0-30-year-old subjects to 80.1 and 68.3%, respectively, in those aged over 60 years. The overall prevalence was much lower in northern Italy, as were the variations from one age group to another, from 28.4% in the 0-30-year-old subjects to 38% in those aged over 60 years. 40.6% of patients with cirrhosis lacked naturally acquired protection against HAV; this percentage was higher in northern (60.5%) than in central (34.9%, P < 0.0001) and southern Italy (27.6%, P < 0.0001). The high prevalence of patients in Italy with chronic hepatitis or cirrhosis who lack naturally acquired immunity to HAV warrants the implementation of vaccination programmes against hepatitis A in such patients.

Abstract
BACKGROUND/AIMS Hepatitis C virus (HCV) infection results in a high frequency of chronic disease. The aim of this study was to identify early prognostic markers of disease resolution by performing a comprehensive analysis of viral and host factors during the natural course of acute HCV infection. METHODS The clinical course of acute hepatitis C was determined in 34 consecutive patients. Epidemiological and virological parameters, as well as cell mediated immunity (CMI) and distribution of human leukocyte antigens (HLA) alleles were analysed. RESULTS Ten out of 34 patients experienced self-limiting infection, with most resolving patients showing fast kinetics of viral clearance: at least one negative HCV RNA test during this phase predicted a favourable outcome. Among other clinical epidemiological parameters measured, the self-limiting course was significantly associated with higher median peak bilirubin levels at the onset of disease, and with the female sex, but only the latter parameter was independently associated after multivariate analysis. No significant differences between self-limiting or chronic course were observed for the distribution of DRB1 and DQB1 alleles. HCV specific T cell response was more frequently detected during acute HCV infection, than in patients with chronic HCV disease. A significantly broader T cell response was found in patients with self-limiting infection than in those with chronic evolving acute hepatitis C. CONCLUSION The results suggest that host related factors, in particular sex and CMI, play a crucial role in the spontaneous clearance of this virus. Most importantly, a negative HCV RNA test and broad CMI within the first month after onset of the symptoms represent very efficacious predictors of viral clearance and could thus be used as criteria in selecting candidates for early antiviral treatment.

Abstract
BACKGROUND Studies of immigrants represent an useful tool to determine the relative relevance of environmental vs genetic factors in causing the reported rapid increase of the prevalence of sensitization and allergic diseases. METHODS A total of 152 Albanian migrants to Southern Italy responded to a questionnaire based on the European Community Respiratory Health Survey (ECRHS) and 139 of them underwent skin prick test, and 61 serological assays for total IgE and IgG antibodies against Toxoplasma gondii (TG), herpes simplex virus 1 (HSV-1), hepatitis A virus (HAV) and Helicobacter pylori (HP). RESULTS Reported asthma was rare (2/152; 1.3%) and reported nasal allergies rather frequent (24/152; 15.8%). Sensitization to common inhalant allergens occurred in 27/139 (19.4%) subjects. The frequency of skin sensitization to pollen (P = 0.003) and that of hay fever (P = 0.004) increased with the time spent in Apulia. All the 61 sera had antibodies against HAV, 59/61 (96.7%) against HSV-1, 48/61 (78.7%) against HP and 34/61 (55.7%) against TG. The prevalence of skin sensitization and hay fever symptoms were correlated to the duration of residence in Southern Italy. CONCLUSIONS Data presented indicate that Albanian migrants to Italy, in spite of the low prevalence of allergic diseases and sensitization in their country of origin, manifest with time an increasing prevalence of sensitization to local allergens and nasal symptoms after immigration to Italy. This would suggest a permanent role of allergen exposure and lifestyle factors in influencing the appearance of sensitization and symptoms of allergic diseases.

Abstract
BACKGROUND In 1992, the characteristics of liver cirrhosis in Italy were assessed in a cross-sectional study among 1829 cirrhosis patients attending 21 tertiary centres. AIM To evaluate the characteristics of cirrhosis patients 9 years later. PATIENTS A total of 2185 consecutive cirrhosis patients were enrolled over a 6-month period in 79 hospitals located throughout Italy, randomly selected by means of systematic cluster sampling. RESULTS The main agent associated with cirrhosis was hepatitis C virus, which was found in 69.9% of the patients and was the only etiologic factor in 51.1% of the patients. Hepatitis B surface antigen was present in the serum of 13.0% of the cases (in 7.3%, it was the only etiologic factor). A history of alcohol abuse was found in 31.9% of the cases (12.4% without viral infection). Patients with hepatitis C virus-related cirrhosis were older (mean age of 64.4 years) and more likely to be female (male:female ratio of 0.7), compared to patients with other pathogenic factors. Virus-related cirrhosis was more likely to be observed in southern Italy, whereas alcohol-related cirrhosis was prevalent in the North. CONCLUSIONS As found in the 1992 study, the results of the present study show that in Italy, liver cirrhosis is mainly associated with hepatitis C virus infection, reflecting the high prevalence of this infection in the general population.

Abstract
OBJECTIVE To investigate a possible correlation between final visual acuity and the presence at baseline of various systemic and local (orbital/ocular) signs in patients affected by indirect traumatic optic neuropathy. METHODS 35 cases of traumatic optic neuropathy were examined retrospectively and 13 variables were tested. Univariate analysis with "no recovery of visual acuity" as the primary outcome was performed. Relative risk (RR) and 95% confidence intervals (CI) were calculated. Fisher's exact test was used for two variables to test differences between proportions. RESULTS Four variables showed a significantly increased risk for no recovery of visual acuity: presence of blood within the posterior ethmoidal cells (RR = 2.25, 95% CI 1.25 to 4.04); age over 40 years (RR = 1.79, 1.07 to 2.99); loss of consciousness associated with traumatic optic neuropathy (RR = 2.21, 1.17 to 4.16); and absence of recovery after 48 hours of steroid treatment (p < 0.01, Fisher's exact test). Recovery documented at the first follow up visit after treatment was significantly associated with recovery at the last follow up visit (p < 0.01, Fisher's exact test). CONCLUSIONS These four negative prognostic signs in patients affected by traumatic optic neuropathy may be useful in predicting the visual outcome in patients developing visual loss after head trauma and in deciding on the need for surgical treatment.

Abstract
PURPOSE To measure visual acuity (VA) on Early Treatment Diabetic Retinopathy Study (ETDRS) charts with a modified faster procedure (ETDRS-Fast), based on adaptive psychophysics methods and to assess the method's validity and reproducibility. METHODS Whereas the standard method for measuring VA with the ETDRS charts requires that the subject read all the letters beginning with the top row, in the ETDRS-Fast procedure, the subject is asked to read only one letter per row until a mistake is made. Then, following simple rules, the examiner finds a row from which the subject can begin reading all the letters downward, thus making the method identical with the standard method near threshold. VA determination was performed twice with both methods in 57 subjects in two separate sessions to assess validity and reproducibility. RESULTS In both sessions the correlation between the two procedures was high (intraclass correlation coefficient 0.95), confirming the validity of the ETDRS-Fast procedure. Reproducibility was good for both procedures, with intraclass correlation coefficients of 0.94 for the standard and 0.96 for the ETDRS-Fast method. The ETDRS-Fast procedure allowed a significantly shorter test duration (-30%; P < 0.0001). CONCLUSIONS Adaptive procedures allow accurate and fast determination of psychophysical thresholds by reducing the number of stimulus presentations when the subject is far from threshold. In the ETDRS-Fast method a few simple rules applied to optotype chart reading allow adaptation to each patient's level of VA. The ETDRS-Fast procedure significantly reduces test time and still yields results that are as accurate as those obtained with the standard method.

Abstract
OBJECTIVE To investigate if markers of exposure to foodborne and orofecal microbes versus airborne viruses are associated with atopy and respiratory allergies. DESIGN Retrospective case-control study. PARTICIPANTS 240 atopic cases and 240 non-atopic controls from a population sample of 1659 participants, all Italian male cadets aged 17-24. SETTING Air force school in Caserta, Italy. MAIN OUTCOME MEASURES Serology for Toxoplasma gondii, Helicobacter pylori, hepatitis A virus, measles, mumps, rubella, chickenpox, cytomegalovirus, and herpes simplex virus type 1; skin sensitisation and IgE antibodies to relevant airborne allergens; total IgE concentration; and diagnosis of allergic asthma or rhinitis. RESULTS Compared with controls there was a lower prevalence of T gondii (26% v 18%, P=0.027), hepatitis A virus (30% v 16%, P=0.004), and H pylori (18% v 15%, P=0.325) in atopic participants. Adjusted odds ratios of atopy decreased with a gradient of exposure to H pylori, T gondii, and hepatitis A virus (none, odds ratio 1; one, 0. 70; two or three, 0.37; P for trend=0.000045) but not with cumulative exposure to the other viruses. Conversely, total IgE concentration was not independently associated with any infection. Allergic asthma was rare (1/245, 0.4%) and allergic rhinitis infrequent (16/245, 7%) among the participants (245/1659) exposed to at least two orofecal and foodborne infections (H pylori, T gondii, hepatitis A virus). CONCLUSION Respiratory allergy is less frequent in people heavily exposed to orofecal and foodborne microbes. Hygiene and a westernised, semisterile diet may facilitate atopy by influencing the overall pattern of commensals and pathogens that stimulate the gut associated lymphoid tissue thus contributing to the epidemic of allergic asthma and rhinitis in developed countries.

Abstract
This study describes the treatments that 253 patients affected by major depressive disorder, according to DSM-III-R criteria, received by their general practitioner prior to their referral to the outpatients clinic of the Department of Psychiatry of the University of Rome "La Sapienza". Out of 253 study subjects only 97 had received prescriptions of antidepressant drugs. In about 50% of these cases (corresponding to 27.4% of the study population) prescribed dosages were inadequate. In 34.7% of subjects who sought medical help antidepressants were not prescribed and other psychotropic drugs (mostly benzodiazepines) or pseudodrugs were used. In 6% of cases no treatment was prescribed. Over one third of the outpatients had been ill for over one year prior to their referral to a psychiatrist. Remedial actions are considered.

Abstract
OBJECTIVE To evaluate whether, in the Italian-American natural history study, cataract surgery in one eye influences the incidence/progression rate of lens opacities in the fellow eye. DESIGN Follow-up study of age-related cataract. PARTICIPANTS A total of 1399 participants with age-related cataracts were regularly followed for 5 years and cataract status evaluated by the Lens Opacities Classification System II on slit-lamp and retroillumination lens photographs. A total of 228 participants had cataract surgery in 1 eye during the study period, and 192 had sufficient follow-up visits to be included in the analysis. MAIN OUTCOME MEASURE The incidence/progression of cataract was defined as two or more consecutive visits with a severity grade greater than the baseline grade. RESULTS When entered into a Cox model, incidence/progression of specific cataract types was not associated with cataract surgery on the fellow eye and was not significantly different from that observed in participants who had no cataract surgery. CONCLUSIONS Cataract extraction does not influence incidence/progression rate of specific lens opacities in the fellow eye.

Abstract
Bronchial hyperresponsiveness (BHR) is a hallmark of asthma and represents a strong risk factor for the disease. However, not all asthmatics have BHR and it can be observed in normal subjects too, probably because of genetic predisposition. Increasing attention is being focused on the beta2-adrenoceptor gene (ADRB2), whose genetic variability at amino acids 16 and 27 has been shown to correlate with some clinical features of asthma, including airways reactivity. To verify whether ADRB2 gene polymorphisms can influence BHR at a broader level, we studied a large, highly homogeneous sample of individuals sharing race, gender, age, and current living environment. BHR was strictly defined as a constant positive response to serial methacholine challenge tests and an improved definition of genetic variability at the ADRB2 locus was used, by identifying the haplotypic combinations of polymorphisms 16 and 27. We observed that the ADRB2 haplotype with a Gly at position 16 and a Gln at position 27 is associated with BHR in our sample. The association persisted also after correction for potentially confounding variables such as specific and total IgE levels. This observation suggests therefore that ADRB2 gene can confer genetic susceptibility to BHR, rather than having only a disease-modifying effect in asthma.

Abstract
BACKGROUND Having a low number of siblings and a low birth order has been reported to be a relevant risk factor for development of atopic diseases and skin sensitization to common inhalants. Although the inverse association of atopy with sibship size has been confirmed repeatedly, the association with birth order has provided conflicting results. This possibly is due to the relatively small size of the population sample examined. OBJECTIVE The objective of this study was to investigate the relation between sibship size, birth order, and atopy in a very large population sample, highly homogeneous for age and sex. METHODS This was a retrospective survey of 11,371 Italian young men, 18 to 24 years old, all candidates for enrollment in the Italian Air Force. Demographic data had been collected by a standard questionnaire. Specific IgE for locally relevant airborne allergens had been tested by a multi-RAST assay (CAP-Phadiatop). RESULTS The prevalence of atopy (defined as a high level of specific IgE against inhalants [cut-point >1.2 log RU]) was inversely related to the total number of siblings (25% in those with no siblings and 9% in those with five or more siblings), with a mean of a 3% decrease in prevalence for each added sibling. This relation persisted after adjustment for relevant variables such as father's education and rural and southern residence. An independent association between birth order and atopy was also observed because the decrease in atopy prevalence with increasing numbers of older siblings was significantly steeper than that found with the number of younger siblings (chi2 = 179, df = 1, p < 0.0001). CONCLUSIONS In a very large and homogeneous population sample of a Mediterranean country, not only sibship size but also birth order was significantly associated with atopy. This observation further highlights the role of family structure in the development of atopy and supports the hypothesis that cross-infections acquired early in infancy or in later childhood might prevent development of atopy later in life.

Abstract
In 1990, to study regional prevalences and risk factors of Helicobacter pylori infection in healthy young adult males, sera were collected from a nationwide sample of 1659 males (mean age 20.7 years) at introduction into the Air Force School for military students in Caserta, Italy. An enzyme-linked immunosorbent assay was used to detect H. pylori specific immunoglobulin G antibodies. The observed overall seropositivity rate was 17.5% (95% CI 15.7-19.4). Prevalence was higher in southern Italy and in the Italian islands as compared with northern Italy and central Italy (21.3% vs. 9.5%). Multiple logistic regression analysis showed that residence in southern areas and islands was the strongest predictor of the likelihood of H. pylori seropositivity; number of siblings in the household was marginally associated; years of father's schooling was not a significant predictor. H. pylori positive subjects were more likely positive for antibodies to hepatitis A virus infection (anti-HAV) than those H. pylori negative (35.4% vs. 24.9%; Odds Ratio 1.7, 95% CI 1.3-2.2). Adjustment for the confounding effect of sociodemographic variables weakened this association (OR 1.3, 95% CI 1.0-1.7). These findings suggest that differences in environmental conditions rather than in socioeconomic status may have played the major role in the different spread of H. pylori infection across the country.

Abstract
PURPOSE To assess intra- and interobserver reproducibility of the Age-Related Eye Disease Study (AREDS) system for grading lens opacities and to provide data on its capacity to reliably detect changes in lens status. METHODS Independent and replicate grading of 40 sets of lens photographs (one slit-lamp and two retroillumination photographs) were performed by three experienced observers. Patients were participants in the Collaborative Italian-American Clinical Trial of Nutritional Supplements which is testing the effect of a mineral-multivitamin supplement on age-related cataract (CTNS). Scatterplots and intraclass correlation were used to assess measurement error. RESULTS Analysis revealed good intra- and interobserver reproducibility of the system. Greatest intraobserver measurement error showed 100% of pairs within 10% areal difference for cortical cataract, 97.5% within 15% areal difference for posterior subcapsular cataract, and 100% within 1 density unit difference for nuclear opacity. Greatest interobserver measurement error showed 95% of pairs within 10% areal difference for cortical cataract, 97.5% within 15% areal difference for posterior subcapsular cataract, and 97.5% within 1.5 density unit difference for nuclear opacity. CONCLUSIONS The AREDS lens opacities grading system appears to be sufficiently reliable to detect changes of at least 10% areal involvement for cortical, 15% areal involvement for posterior subcapsular, and 1.0 units for nuclear opacities. It therefore seems sufficiently sensitive to adequately monitor progression of lens opacities in a longitudinal study of patients with early cataract. Its applicability in a population with advanced or complex mixed opacities must await further testing.

Abstract
OBJECTIVE To investigate the working hypothesis that common infections occurring early in life prevent atopy. DESIGN Cross sectional, retrospective study of young Italian men with results for hepatitis A serology and atopy. SETTING Air force school of military students in Caserta, Italy. SUBJECTS 1659 male students aged 17-24, most of whom (90%) were from central and southern Italy. MAIN OUTCOME MEASURES Skin sensitisation and specific IgE antibodies to locally relevant airborne allergens; diagnosis of respiratory allergy (asthma or rhinitis, or both); hepatitis A seropositivity. RESULTS 443 of the 1659 subjects (26.7%) were positive for hepatitis A virus antibody. Atopy was less common among seropositive than seronegative subjects according to skin sensitization (weal reaction > or = 3 mm) to one or more allergens (21.9% (97/443) v 30.2% (367/1216), P < 0.001); polysensitisation (sensitive to three or more allergens) (2.7% (12/443) v 6.4% (78/1216), P < 0.01); high specific IgF concentration (9.7% (43/443) v 18.4% (224/1216), P < 0.00005); and lifetime prevalence of allergic rhinitis or asthma, or both (8.4% (37/443) v 16.7% (203/1216), P < 0.001). Hepatitis A seropositivity remained inversely associated with atopy after adjusting for father's education, the number of older siblings, and the area of residence (based on the number of inhabitants). The prevalence of atopy was constantly low among seropositive subjects, whatever the number of older siblings; by contrast, it increased with a decreasing number of older siblings among seronegative subjects. CONCLUSION Indirect but important evidence is added to the working hypothesis as common infections acquired early in life because of the presence of many older siblings (among seronegative subjects) or because of unhygienic living conditions (among seropositive subjects) may have reduced the risk of developing atopy.

Abstract
Over the period 1989-1991 a case-control study was carried out in the area of Naples comparing 162 subjects with acute hepatitis B and 788 hospitalized control subjects. The results of multivariate analysis showed that surgical intervention (odds ratio 3.8; 95% CI 1.2-11.7), household contact with an hepatitis B surface antigen (HBsAg) positive carrier (odds ratio 2.7; 95% CI 1.1-6.7) and intravenous drug use (odds ratio 13.0; 95% CI 3.2-52.7) were risk factors independently associated with hepatitis B. No association was found with the other risk factors considered, such as blood transfusion, hospitalization, other percutaneous exposures, dental therapy, contact with an icteric case, barber shop shaving and two or more sexual partners. As a significant proportion of the general population undergoes surgical intervention, efficient procedures for sterilization of instruments should be implemented, together with the use of disposable materials, to control the spread of HBV infection in surgical settings.

Abstract
UNLABELLED This paper concerns one of the four research projects developed during a training course in clinical epidemiology managed by the Lombardy training centers IREF. OBJECTIVES To compare the recommendations for treatment concerning 9 vignettes derived from the Australian Quality Assurance Project. SETTING Six Mental Health Services of Regione Lombardia. DESIGN AND PARTICIPANTS For each vignette, all psychiatrists working in the 6 Mental Health Services were asked to fill in a questionnaire about treatment location, psychopharmacology, psychotherapy, priority between psychotherapy and psychopharmacology and degree of difficulty in answering. RESULTS 44 out of 52 target psychiatrists took part to the study. Remarkable variability for treatment location and psychotherapies; moderate variation for psychodrugs prescriptions and a good agreement for diagnoses were observed. In drugs prescription an access of association was observed. The most prevalent model of psychotherapy was the psychodynamic, followed by the cognitive-behavioural and the family-systemic. There was a tendency toward a flexible approach, as suggested by recommendations of different psychotherapeutic models according to the nature of the disorder. No case were judged very difficult; only in 3 cases a judgement of "somewhat difficult" was expressed by more than 20% (but less than 30%) of the psychiatrists. CONCLUSIONS Studies of this type are very easy to carry out and give useful information for continuous training programs and Continuous Quality Improvement projects.

Abstract
PURPOSE To examine the distribution of cortical opacities across the lens in the Italian-American Natural History Study of Age-Related Cataract and to study the association between an index of sunlight exposure and the location of cortical cataract within the lens. METHODS Lens photographs of one eye of 731 persons with cortical opacities (503 with pure and 228 with mixed types of opacity) were included in the analysis. A radial grid superimposed on the photographs was used to assess presence, location, and severity of wedge-shaped cortical opacities. RESULTS Both the prevalence and the extent of cortical opacities were highest in the inferior-nasal quadrant and lowest in the superior-nasal quadrant of the lens. In polychotomous logistic regression, persons with the greatest excess areal involvement in the inferior half of the lens were more likely to have high exposure to sunlight, as measured by a sunlight index, than persons with excess involvement in the superior half of the lens (odds ratio, 1.73; 95% confidence interval 1.03, 2.93). Excess areal involvement of the inferior lens also was associated with the pure type of cortical cataract and with the total extent of the opacity. CONCLUSIONS Age-related cortical opacities occur more frequently inferiorly than superiorly and, to a lesser extent, nasally than temporally. Possibly higher exposure of these lens segments to sunlight may explain this preferential location of cortical opacities.

Abstract
PURPOSE To compare the distribution of cataract types at surgery with the distribution detected in an ophthalmology clinic-based case-control study in the same geographic area (Parma, Italy). METHODS The distribution of cataract type assessed according to the Lens Opacities Classification System I in 284 consecutive patients 45 years of age or older, who were admitted for cataract surgery to the Institute of Ophthalmology in Parma during 1994, was compared with the distribution assessed in 1008 participants in the Italian-American case-control study of age-related cataract in the Parma metropolitan area from 1987 to 1989. RESULTS Analysis of cataract distribution indicates in the surgical group, compared with the case-control population, a significant increase of nuclear (N) and posterior subcapsular (PSC) opacities (any), a reduction of pure forms of cortical and N cataracts, and a marked increase of mixed types of opacities with a simultaneous N and PSC component. CONCLUSION Although cortical opacities are probably the most prevalent type of age-related lens change in the general population of Parma metropolitan area, the type of cataract most frequently responsible for the decision of patients to undergo cataract surgery is a mixed type of opacity with an N-PSC component.

Abstract
An increased incidence of hepatitis A was observed in Naples from 1990-1991. A hospital-based case-control study was carried out to evaluate the relative importance of various risk factors. A hundred and ninety-eight cases and 238 hospital controls were recruited during the study period. The strongest association was contact with a jaundiced person among children. A correlation was also shown for children and adults with raw shellfish consumption and pre-school nursery attendance or presence in the household of children attending pre-school nurseries. History of travel and intravenous drug use were risk factors for adult subjects. Considering the relative importance of the specific risk factors we found that 38% of the acute hepatitis A cases were attributable to contact with a jaundiced person, 15% to presence in the household of children attending pre-school nurseries and 28% to raw shellfish consumption.

Abstract
The incidence of hepatitis Delta virus in the general Italian population was estimated by a specific surveillance system for acute viral hepatitis over the period 1987-1992. The hepatitis Delta virus incidence rate declined from 3.1/1,000,000 inhabitants in 1987 to 1.2/1,000,000 in 1992. Males predominated (83.8% of cases); the sex ratio was 5.2. Only 2.5% of cases occurred in subjects younger than 15 years. There were 119 (49.4%) coinfections of Delta and B hepatitis and 122 (50.6%) Delta superinfections in chronic HBsAg carriers. Jaundice was present in 83.6% of cases. The hospitalization rate was 97.5%; median stay in hospital was 25 days (range 1-98 days). The results of multivariate analysis showed that a history of intravenous drug abuse (odds ratio 34.9; confidence interval 95% = 16.8-72.5), household contact with an HBsAg+ carrier (odds ratio 10.7; confidence interval 95% = 4.36-23.30) and a history of two or more sexual partners within the previous 6 months (odds ratio 2.44; confidence interval 95% = 1.34-4.43) were independent risk factors associated with Delta hepatitis. No association was found with the other risk factors considered, such as blood transfusion, surgical intervention, hospitalization, other percutaneous exposures, dental therapy, contact with an icteric case, and household contact with an i.v. drug abuser. These findings indicate that, in Italy, Delta hepatitis currently has a minor impact. In addition to intravenous drug abuse and household contact with an HBsAg+ carrier, heterosexual activity appears to be an efficient route of HDV transmission.

Abstract
A case-control study was carried out comparing 333 case subjects with non-A, non-B hepatitis and 1095 hospital control subjects. Of 333 case subjects, 197 (59%) were positive for hepatitis C antibody (anti-HCV). Excluding blood transfusion and intravenous drug use, surgical intervention and dental therapy were strongly associated with anti-HCV-positive cases: in particular, obstetric and gynecology surgical intervention was found to be strongly associated with HCV positivity (odds ratio [OR] = 32; 95% confidence interval [CI] = 7, 147). Raw shellfish consumption was a risk factor for anti-HCV-negative cases (OR = 2.2; 95% CI = 1.0, 5.1), thus suggesting an enterically transmitted virus in sporadic non-A, non-B hepatitis in Italy.

Abstract
The objectives of the present report were to give a baseline picture of hepatitis B notification incidence rates in children before the campaign of mass vaccination for newborns and adolescents (12-13 years old), and to study the role of different risk factors. Data from a specific national surveillance system of acute viral hepatitis (SEIEVA, Sistema Epidemiologico Integrato dell'Epatite Virale Acuta) were used and acute hepatitis B cases were compared to acute hepatitis A patients with the case-control study method to estimate the associations with the considered risk factors. Since the system began, one hundred and sixty-three local health departments have joined SEIEVA covering 30% of the Italian population. The incidence of acute hepatitis B notifications among 0-14 aged children was 9 per 100,000 in 1985 and 1 per 100,000 in 1990. Such decline in incidence was observed in both the North and the South of Italy. Surgical interventions, dental therapy and household contacts with a HBsAg chronic carrier were found to be associated with acute hepatitis B. The point estimate of the odds ratio was 10 for the latter risk factor. Other preventive measures in addition to vaccination are needed to control the risk of hepatitis B infection and other parenteral diseases due to surgical intervention and dental therapy.

Abstract
530 patients with localised cutaneous melanoma consecutively observed between 1980 and 1991 at a hospital for skin diseases in Rome, Italy, were studied. Crude survival proportions were calculated with the method of Kaplan and Meier. Cox proportional hazards regression analysis was used to estimate the effect of prognostic factors on death rates. Females and younger patients had better 5- and 10-year survival rates, while increasing tumour thickness was associated with a decrease in survival time. In the multivariate analysis, an independent association with survival was found for tumour thickness, presence of ulceration, age, sex and cross-sectional profile of neoplasia. Our study confirms that females and young patients with thin melanomas have a better prognosis, while the importance of cross-sectional profile needs further study.

Abstract
A household health interview survey on MCH services utilization was carried out in 22 villages of a rural district of Arsi region, Ethiopia, before the launching of an integrated MCH programme. Coverage of antenatal services was 26%, and 61% of the women who received antenatal care reported having had 3 or more visits. Antenatal care was positively associated with living within 10 km of the Health Centre. Twenty-eight percent of the mothers attended the under-5 clinic and most returned for 3 or more visits. In addition, 99% reported having breast-fed their last child but more than 25% started weaning only after the seventh month of age. Differences in practice of treating diarrhoea according to knowledge of ORS were found. Of the 33% of those with knowledge of ORS, almost 90% reported use of ORS for treating child's diarrhoea, showing a positive attitude towards modern health care. The proportion of women using family planning was 5%, with no difference found between Christians and Muslims. Results on EPI coverage validated data from routine reporting. Integration of MCH services including out-reach activities may increase access and coverage of MCH services.

Abstract
A census and an ecologic survey were performed in 39 villages of a rural district of Arsi Region, Ethiopia, in difficult field circumstances. Information on age, ethnic group, education and family relationship, as well as data on health facilities and availability of basic services were collected. Supervised students, working in teams, were used as interviewers. Communities were involved through plenary meetings and community health agents participated in the data collection process. A total of 64,714 people in 12,152 households were registered. The repeatability of age assessment was investigated by comparing the results from two villages with data obtained in a pilot study carried out 6 months earlier. The technical error was only 0.80 and 1.67 in the 0-5 and 6-15 age-groups, respectively. Three percent of the total population was under one year, less than previously estimated. This may, in part, be due to the family planning programme in the region. Eighteen percent of the households were headed by females. School attendance was less common among females and in the Oromo ethnic group. The availability of basic services, including safe water and basic sanitation supplies, was very poor in the area.

Abstract
In Italy, a dramatic decline of hepatitis B infection occurred in recent years as a result of nonmedical and medical factors. The national type-specific surveillance system shows that the age of maximum incidence changed from early childhood, when the risk of becoming a chronic carrier after infection is very high, to late adolescence. Data of several seroepidemiologic studies are consistent with this picture, but could not be compared with previous data on similar age groups. In 1981, a seroepidemiologic study on a national sample of 5,005 recruits showed a high prevalence of serologic markers of hepatitis B infection among young adults in Italy. In 1990, the authors replicated that original study on a national sample of 4,993 recruits. The adjusted prevalence of hepatitis B core antibodies among Italian male recruits dropped from 16.8% to 5.8% in 9 years. The authors anticipate a substantial reduction in the rate of production of chronic carriers and the rates of liver cirrhosis and primary liver carcinoma in Italy in the next decades. Vaccination campaigns, especially if combined with nonimmunologic preventive measures, will further reduce the rate of hepatitis B infection in Italy.

Abstract
To assess the prevalence of HIV-1 infection and study selected risk factors among patients attending a clinic for sexually transmitted diseases in Rome, 1442 outpatients seen consecutively between 20 February and 12 December 1989 were anonymously tested for anti-HIV-1. An evaluation of the trend of the HIV-1 infection was attempted by comparing the results of the present study with those obtained from a similar sample studied in 1986 in the same clinic. The overall estimated prevalence of anti-HIV-1 was 1.2% among heterosexual non-drug user subjects and 16.1% among homosexual or bisexual men. The anti-HIV-1 seropositivity was significantly higher in heterosexual subjects who reported sexual contact with intravenous drug users, as compared with those who did not report such exposure (12.5% vs 0.8%, p less than 0.005). Comparing the present data with those of a study conducted in 1986 in the same clinic, a lower prevalence of anti-HIV-1 was found among heterosexual subjects (1.2% in 1989 vs 6.0% in 1986, p less than 0.001). The availability after 1986 of several outpatient facilities attracting seropositive subjects and a change in the sexual behaviour of anti-HIV-1 positive subjects could explain this finding. Twenty percent of the heterosexual subjects and 62% of the homosexual or bisexual men reported consistent use of condoms.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A seroprevalence study was carried out on 1757 outpatients consecutively seen in a sexually transmitted disease (STD) clinic in order to evaluate the sexual transmission of hepatitis C virus (HCV). A total of 1442 consenting patients were tested for hepatitis C, hepatitis B and human immunodeficiency virus type 1 (HCV, HBV, HIV-1) antibodies. The relations between anti-HCV, anti-HBc and anti-HIV-1 were studied. Of 73 anti-HCV positive reactions, 45 (61.6%) were confirmed by the recombinant immunoblot assay (RIBA). The proportion of individuals with anti-HCV was higher in outpatients with a history of sexually transmitted disease than without. It was 2.8% in non drug user heterosexuals and 2.9% in non drug user homosexuals. Intravenous drug users (IDU) had higher anti-HCV prevalence when a history of STD was taken into account (42.3% in subjects with STD versus 36.7% in subjects without STD). Among non drug user heterosexuals an association was found between anti-HCV and anti-HBc. These data suggest that sexual transmission of HCV occurs, although it seems to be less efficient than other parenteral modes of transmission. When a more sensitive and specific marker of HCV infection become available, a more accurate estimate of the frequency and efficiency of the sexual transmission will be possible.

Abstract
A specific surveillance system for acute viral hepatitis which uses weekly notification of cases and a standard risk factor questionnaire was started in Italy in 1984. From 1985 to 1988 153 Health Departments (27% of Italian population) joined the system. Estimated incidence of reported viral hepatitis was 30 per 100,000 in 1985 and 14 in 1988. The decline was impressive for hepatitis A, particularly in the south. Reduction of incidence was also evident for hepatitis B and Non-A, Non-B hepatitis, particularly in young adults. The decrease of viral hepatitis in Italy is consistent with recent seroepidemiological data. Shellfish consumption was the most frequent risk factor reported for hepatitis A cases at all ages. Hospitalization, surgical intervention, dental therapy and other percutaneous exposures still play a role in the transmission of parenteral hepatitis in Italy. Blood transfusions seem to be important only for Non-A, Non-B. Interventions other than vaccination to prevent B and Non-A, Non-B hepatitis due to hospitalization, surgical intervention, other percutaneous exposures and dental therapy are needed and can further contribute to the decline of hepatitis virus infection rates in Italy.
