Simit epidemiological multicentric study on hospitalized immigrants in Italy during 2002.

The aim of this article is to retrospectively evaluate the patient characteristics and the most common infectious diseases in immigrant patients hospitalized in 46 Italian infectious disease clinics during 2002. The main Italian infectious disease clinics were invited to fill in a questionnaire that regarded the number and type of hospital admissions, the country of origin, and demographic features (age, sex, and resident state) of immigrants. A total of 46 clinics including 2255 patients participated in the study. Most patients were men (63%) with an age between 16 and 40 years (63.4%) covered by the National Health Service (71%) and coming from Africa (44.3%). The main infectious diseases observed were: 378 (16.76%) cases of HIV infection, 303 (13.43%) cases of tuberculosis diseases, 282 (12.5%) cases of various forms of viral hepatitis, 177 (7.84%) cases of respiratory diseases, and 196 (8.69%) gastrointestinal diseases. Tropical diseases found were 134 (5.94%) including 95 cases of malaria (70.9%). In conclusion, a broad range of diseases was noted in immigrants which were directly correlated with conditions of poverty. Only a few tropical diseases were diagnosed and therefore the immigrant should not be considered as an infectious disease carrier.

Prevalence of HIV infections in hospitalised immigrants in Clinics of Infectious Diseases in Italy: a multicentric survey.

Our aim was to evaluate the prevalence of HIV infection in immigrants hospitalised in infectious disease settings in Italy during 2002. Each participating centre filled in a CRF which regarded the number of immigrants hospitalised in ordinary regime or in day-hospital during 2002 and, for HIV-positive patients only, some demographic (age, sex, origin) and clinical features (only HIV positivity or AIDS, new diagnosis or not, diagnosis of opportunistic infections). A total of 46 Infectious Diseases Units participated in the study and a total number of 2255 patients were tested for anti-HIV, irrespective of the cause of hospitalization, with 378 (16%) cases of positivity. Women accounted for 47.9%; the mean age of the population was 34.5 years. African patients showed a higher prevalence of HIV infections than subjects from other geographical areas (61.9% of all cases). Most HIV-infected patients were unaware of their positivity. In conclusion, HIV infection represents one of the main health problems among immigrants, particularly of African origin.

Acute hepatitis induced by cyproterone acetate.

OBJECTIVE: To report a case of acute hepatitis resulting from the use of cyproterone acetate, an adjuvant treatment for prostate cancer. CASE SUMMARY: An 87 year-old white man, admitted to surgery for prostate cancer, received cyproterone acetate 300 mg/d orally and developed acute hepatitis, which initially was diagnosed clinically. A liver biopsy showed changes suggestive of acute cholestatic hepatitis. Cyprotorone was stopped immediately, and the patient was subsequently treated with corticosteroids. He then improved rapidly. DISCUSSION: Cyproterone acetate is thought to be well tolerated, but some authors have reported severe hepatic reactions, in particular acute hepatitis, fatal fulminant hepatic failure, and hepatocellular carcinoma. The above-mentioned hepatotoxicity represents an idiosyncratic drug reaction, probably due to the hepatomitogen action of cyproterone, causing an increase of hepatocytes expressing placental glutathione S-transferase, which are considered preneoplastic elements. CONCLUSION: This case suggests the possibility of hepatotoxicity from cyproterone.

[Molecular genetics and bone diseases].

The authors describe the molecular mechanisms determining some skeletal diseases, in particular those due to a well-defined, single genic defect. In fact, they examine the hereditary disorders due to mutations in the genes encoding the different collagen types and the hereditary diseases secondary to the defects in: a) the structural proteins of cartilage; b) the enzymes and the sulfate transporters of proteoglycans; c) the transcription factors; d) the growth factors. At the end, the authors emphasize the importance of the genetic studies on animal models, for understanding the etiopathogenesis of many human hereditary disorders.

[Usefulness of online bibliographic research in biomedical research, with an application to the epidemiologic study of genetic osteopathy].

The bibliographic research online is an useful means of recovering information in all the subjects, particularly in the field of biomedicine. In fact, this instrument allows researchers to get information in a rapid, complete and up-to-date way. The aim of the present review is to describe the usefulness of the bibliographical research online in the field of the genetic osteopathies. These are rare disorders: so, their own rarity makes the bibliographical research online necessary to carry out a large and effective comparison of experiences. The obtained results are amply reported in the manuscript. For instance, we verified that chondrodysplasias are the diseases most represented in the literature, while melorheostosis the disorder less mentioned. Moreover, we evidenced that some hereditary disorders of connective tissue, such as Marfan's syndrome, osteogenesis imperfecta and Ehlers-Danlos syndrome, are strongly influenced by race, sex and age.

[Sexually transmitted diseases among immigrants in Italy].

In Italy, most foreign residents are between the ages of 19 and 40 years and are sexually active. Data from the Italian national STD surveillance system, a nationwide network of public STD clinics, show that over 10% of the reported cases of STD are diagnosed among these individuals. Furthermore, the mobility of foreign populations and problems with access to health care facilities can contribute to the spread of these diseases. This report presents data on over 4000 STD patients and on 1103 AIDS patients among foreign residents in Italy and includes a discussion of strategies for providing adequate STD care and for promoting prevention.

Immigration and health: the Italian National Focal Point experience.

This report is a description of the situation of migrant populations in Italy. It was written by a committed team of experts from public institutions, non-governmental organisations (NGO) and volunteer associations that for three years have been part of the Italian National Focal Point (NFP) within the European Project "AIDS & Mobility", which is being co-ordinated by the Netherlands Institute for Health Promotion and Disease Prevention (the Netherlands) and financed by the European Commission DG/V. This year the Italian National Focal Point, co-ordinated by the Telefono Verde AIDS of the Istituto Superiore di Sanità, has produced a second report (the first one was published in 1998) on health issues related to migrant populations. Besides providing an updated picture on the presence of foreigners in Italy, such report illustrates the present legislative situation within the sanitary area and some interventions regarding prevention, treatment and rehabilitation provided by each structure in the Italian NFP to foreign citizens. The initiatives carried out during the year 1999 by public institutions, NGO and volunteer associations are also reported in order to detect the psycho-social-sanitary needs of immigrants and target prevention programmes to their particular and specific needs.

Multiple cocaine-induced seizures and corresponding cocaine and metabolite concentrations.

The etiology of seizures associated with cocaine use is unclear. Because cocaine seizures are relatively uncommon, they should be diagnosed by exclusion and a neurological workup to rule out central nervous system (CNS) catastrophe should be made. This report describes the clinical findings, treatment, and blood cocaine and metabolite concentrations in a patient who, on two separate occasions, had seizures associated with crack cocaine ingestion. Approximately 1 hour after the ingestion incidents, the patient had multiple, generalized seizures that abated spontaneously. His workup for CNS bleeding, infection, and trauma was negative. Cocaine concentrations on the first incident peaked at 2.48 mg/L and on the second incident peaked at 3.9 mg/L. Other clinical findings included tachycardia, hypertension, diaphoresis, and disorientation. Blood cocaine and metabolite analysis revealed extremely high concentrations. Other than the incident of seizures and transient cardiovascular aberrations, these high concentrations were tolerated by the patient without further sequelae. A review of cocaine-induced seizures and treatment is included.

Immigration and health: the Italian situation. Italian National Focal Point (NFP) of the AIDS & Mobility Project.

This report is a description of the situation of migrant populations in Italy. It was written as part of the European project "AIDS & Mobility", which is being co-ordinated by the Netherlands Institute for Health Promotion and Disease Prevention and financed by the European Union (EU). The report was written by the Italian National Focal Point (NFP) of the AIDS & Mobility Project, which consists of a committed team of experts from public institutions, non-governmental organizations, volunteer associations, and researchers from the Telefono Verde AIDS (National AIDS Help-line of Italy) of the Centro Operativo AIDS (COA, National AIDS Unit of Italy) of the Istituto Superiore di Sanità. The report illustrates the phenomenon of immigration in Italy, with demographic data (updated at 31 December 1997) on the presence of non-Italians and a review of the current laws pertinent to this phenomenon, with particular reference to health care laws. Moreover, epidemiological data on HIV/AIDS and on sexually transmitted diseases are provided, particularly as they relate to drug addiction and prostitution. Finally, following an accurate analysis of the situation and in light of the experience gained, the report includes proposals for identifying needs, objectives to pursue, and strategies to adopt, with respect to confronting the issue of immigration.

Determinants of tuberculosis in an immigrant population in Rome: a case-control study.

SETTING: An out-patient clinic for immigrants in Rome, Italy. OBJECTIVE: To determine risk factors for tuberculosis among immigrants in Italy. DESIGN: Case-control study. Cases comprised 44 individuals aged 15-55 years who had a first diagnosis of tuberculosis between 1989 and 1994 at the clinic. Controls comprised 264 individuals randomly recruited among immigrants who attended the clinic for other reasons within seven days before or after the case was diagnosed. Subject information included country of origin, date of first arrival in Italy, level of education, knowledge of the Italian language, and legal resident status. RESULTS: An increase of tuberculosis risk was observed with increasing tuberculosis incidence in the country of origin. Multivariate analysis showed an increased risk for those coming from Central and South America (odds ratio [OR] 5.5; 95% confidence interval [CI] 1.6-18.7). The adjusted odds ratio by time since entry in Italy increased during the second year of residence (OR 2.8; 95% CI 1.1-7.0), but decreased after that period. A trend toward increasing risk with decreasing educational level was observed. CONCLUSIONS: These results demonstrate the need for a public health policy in Italy for tuberculosis control among immigrants which includes screening, prophylaxis and treatment.

Predictors of major in-hospital ischemic complications and length of hospital stay after coronary stenting.

Although recent data show that coronary stenting reduces procedural complications and late restenosis, major concern has been expressed about the greater hospital cost associated with the use of this device as compared to conventional coronary angioplasty. Since length of hospital stay after surgical procedures is a major determinant of resource use, the identification of variables associated with an excessively long hospital stay after intracoronary stent placement may have important practical consequences. The purpose of this study was to assess factors responsible for the occurrence of in-hospital complications and prolonged hospital stay after coronary stenting in 939 consecutive patients enrolled in the Registro Impianto Stent Endocoronarico (RISE Study Group). Consecutive patients undergoing coronary stent implantation at 16 medical centers in Italy were prospectively enrolled in the Registry. Clinical data, qualitative and quantitative angiographic findings were obtained from data collected in case report forms at each investigator site. Major ischemic complications were considered death, Q-wave myocardial infarction, emergency bypass surgery and emergency repeat angioplasty. The study group consisted of 939 patients (781 men, 158 women with a mean age of 59 years) in whom 1392 stents were implanted in 1006 lesions and expanded at a maximal inflation pressure of 14.7 +/- 3 atmospheres. The great majority of patients (92%) received only antiplatelet drugs after coronary stenting. During hospitalization, there were 45 major ischemic complications in 39 patients (4.2%): 13 events were related to acute or subacute thrombosis (1.4%). On multivariate logistic regression analysis, the following factors were predictive of in-hospital complications: increasing age (OR 2.19, 95% CI 1.18-4.07), unplanned stenting (OR 3.46, 95% CI 1.65-7.23) and maximal inflation pressure (OR 0.83, 95% CI 0.75-0.93). Mean hospital stay after stent implantation was 4.1 +/- 4.4 days and was related, by multivariate regression analysis, to female sex (p = 0.0001), prior bypass surgery (p = 0.03), non-elective stenting (p = 0.0001), use of anticoagulation (p = 0.0001) and development of major ischemic complications (p = 0.0001). This Registry shows that in an unselected population of patients undergoing coronary stenting, major ischemic complications occur at a relatively low rate (4.2%) and thrombotic events can be kept at 1.4%, despite the omission of anticoagulation in the great majority of patients. Length of hospital stay was affected by the occurrence of major ischemic complications, unplanned stenting, use of anticoagulation, female sex and prior bypass surgery. Accumulating experience, further reduction in complications and complete omission of anticoagulation may decrease length of hospital stay, thus reducing the use of resources after coronary stenting.

[Lung tuberculosis in HIV positive patients. Clinico-radiologic correlations].

UNLABELLED: We investigated the radiologic features of pulmonary tuberculosis in HIV+ patients. SUBJECTS AND METHODS: 24 cases of pulmonary tuberculosis in HIV+ patients were studied (17 men and 7 women, average age: 38 years). The study includes 19 drug addicts, 3 homosexuals, 1 polytransfused subject and 1 patient not belonging to the categories considered at risk). Three subgroups were identified by the CD4/mm3 cell count (< 200, 200-500, > 500). RESULTS: In our 24 patients, we identified 37 radiologic manifestations (in 13 cases associated in the same patient), with 6 cases of bilateral pulmonary and 9 atypical localizations. In detail: 10 consolidations, 7 productive (miliary) cavitations, 8 mediastinal lymphadenitis, 3 extrapulmonary forms and 4 cases with no chest X-ray alterations. There is a major frequency of consolidations and cavitations in the patients with CD4 > 200 and a major frequency of productive forms, lymphadenitis and extrapulmonary localizations in the subjects with CD4 < 200. We observed no cases of tuberculosis in patients with CD4 > 500. The medical therapy is usually more effective in the more immunocompetent subjects and, anyway, in the exudative forms, improving in 35% of cases, than in the productive and disseminated forms improving in 6% of cases only. DISCUSSION AND CONCLUSIONS: Only the severely immunodeficient HIV+ patients (CD4 < 500) are affected with tuberculosis. There exists a significant rate of parenchymal consolidations and tisiogenic forms in subjects with CD4 > 200 and a high rate of miliary forms, lymphadenitis and extrapulmonary localizations in patients with low cell count (< 200). The medical therapy is more effective in the more immunocompetent subjects and, anyway, in the exudative forms, than in the productive and disseminated forms. Finally, atypical localization of pulmonary tuberculosis are frequent in HIV patients.
