An estimate of the current risk of transmitting blood-borne infections through blood transfusion in Italy
No full textWe conducted a retrospective cohort study to estimate the incidence of major blood-borne agents among Italian blood donors and calculated the risk of infection among blood recipients using the 'incidence/window period model'. The study was conducted among 46 180 blood donors enrolled in six blood centres between 1994 and 1999. During follow-up, seven new infections were confirmed: three donors seroconverted for anti-human immunodeficiency virus (HIV); two for anti-hepatitis C virus (HCV); and two showed hepatitis B surface antigen (HBsAg) reactivity; no cases of syphilis were observed. The incidence rates per 100 000 person/years were: 4.06 (95% CI: 0.82-11.85) for HIV; 2.41 (95% CI: 0.29-8.70) for HCV; and 2.70 (95% CI: 0.32-9.77) for HBsAg; the incidence for total hepatitis B virus (HBV) infection was 9.77 per 100 000 person/years (95% CI: 1.16-35.36). The estimated risk of an infectious blood unit not being detected was: 2.45 (95% CI: 0.13-12.33) per 1 million units for HIV; 4.35 (95% CI: 0.30-22.39) for HCV; and 15.78 (95% CI: 1.16-84.23) for HBV. Overall, an estimated 22.58 per 1 million units are infected. In Italy, the risk of transfusion-transmitted infections is low and is similar to that in other western countries. The introduction of new more sensitive screening tests could reduce the residual risk of transfusion-transmitted infection by 40-80%
Environmental effects on immune system and allergy.
No full textIncidence and severity of allergic diseases of the upper and lower airwys has been increasing throughout this century. The hallmark of these disorders is increased IgE production. Many epoidemiological studies have provided indirect evidence for an increased incidence of asthma and atopy linked to airborne pollution in developed countries. In order to better understand the complex interaction(s) between pollution and allergic diseases, we suggest to consider four fundamentl mechanisms. 1. Increased concentration of airborne allergens in urban areas and workplaces. 2) Adjuvant effect. 3) Xenobiotic interaction(s) with immune system. 4) Effects of pollutants on target organs. In conclusion, although epidemiological and laboratory studies show contrasting results, there is evidence that xenobiotics are involved in the pathogenesis of allergic diseases through specific and non-specific mechanisms

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Therapeutic approach in pulmonary mycetoma. Analysis of 27 patients
No full textBACKGROUND:
Pulmonary mycetoma is a characteristic clinical-radiological lesion due to colonization of aspergillus or candida species in pre-existing pulmonary cavities following a number of diseases.
METHODS:
We revisited 27 records of such admitted patients (19 M, 8 F; range age 16-27 yrs) analysing diagnostic approach and therapy. Predisposing conditions were sequelae of tuberculosis or lung abscess, bronchiectasis, bullous emphysema, leukaemia/ lymphoma, diabetes mellitus, corticosteroids and/or immunosuppressant administration and antiblastic chemotherapy. All patients had a characteristic chest X-ray and the most common symptoms were cough and haemoptysis. Diagnosis of pulmonary mycetoma was based on positive sputum culture for aspergillus or candida species and/or positive result for aspergillus precipitin test. Eleven patients received only medical treatment, eight pts only a surgical one and eight patients both medical and surgical ones. Antifungal drugs administered were itraconazole or amphotericin B or fluconazole.
RESULTS:
In the follow-up, six out of eleven patients who had received only medical treatment, cannot be found; five patients or their relatives were interviewed by phone: two of them enjoyed good health and three had died. Sixteen patients underwent thoracic surgery and one of them died because of postsurgical complications. In the follow-up, only nine patients out of this last group were interviewed by phone 2 to 8 years after surgery: seven of them enjoyed good health while two patients had died because of disease not related to pulmonary mycetoma.
CONCLUSIONS:
Aspergilloma treatment is related to the extension of disease and clinical conditions of patients but surgical resection associated with drug administration, when possible, is the treatment of choice
