Aim In the context of the Italian Multicentric Epidemiological Study on Risk Factors for Childhood Leukaemia and Non-Hodgkin's Lymphoma (SETIL), the risk of childhood cancer was investigated in relation to parental occupational exposures. Methods All cases of childhood leukaemia and non-Hodgkin's lymphoma (NHL) in children aged 0-10 years were identified. Controls were chosen at random from the local population in each region. Parents were interviewed using a structured questionnaire. The collected data were blindly reviewed by expert industrial hygienists in order to estimate exposure to a list of agents. Statistical analyses were performed for each agent using unconditional multivariable logistic regression models, taking into account timing of exposure. Results 683 cases of acute childhood leukaemia, 97 cases of NHL and 1044 controls were identified. Increased risk of childhood leukaemia was found for maternal exposure to aliphatic (OR 4.3) or aromatic hydrocarbons (OR 3.8) in the preconception period, and for paternal exposure to diesel exhaust (OR 1.4), lead exposure (OR 1.4) and mineral oils (OR 1.7). Risk of NHL appeared to be related to paternal exposure to oxygenated solvents (OR 2.5) and petrol exhaust (OR 2.2). Conclusions We found increased risk for childhood leukaemia associated with maternal occupational exposure to aromatic and aliphatic hydrocarbons, particularly in the preconception period; increased risks were also observed for paternal exposure to diesel exhaust fumes, mineral oils and lead. The risk of NHL appeared to be related to paternal exposure to oxygenated solvent and petrol exhausts. Source

The objective of this study was to analyse time-related aspects of the use of fertility drugs related to the risk of endometrial cancer using data from a case-control study conducted between 1992 and 2006 in Italy. The study included 454 cases (median age, 60 years; range, 18-79) with incident, histologically confirmed endometrial cancer and 908 female controls (median age, 61 years; range 19-79) admitted to the same network of hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. Controls were frequency matched to cases with a 2 : 1 ratio for age and study centre. Information was collected by trained interviewers using a structured questionnaire. We calculated odds ratios (ORs) and the corresponding 95% confidence intervals (CI) using conditional logistic regression models adjusted for major relevant covariates. The OR of endometrial cancer for ever use of fertility drugs was 3.26 (95% CI, 1.07-9.95). The risk was higher for duration of use 12 months or more (OR=6.10; 95% CI, 0.96-38.6), time since last use 25 years or less before the interview (OR=5.30; 95% CI, 1.12-25.1), and for age at first use less than 30 years (OR=5.14; 95% CI, 1.13-23.4). The association was apparently stronger in ever-gravid (OR=6.50; 95% CI, 1.10-38.3) than in nulligravid (OR=2.83; 95% CI, 0.32-25.0) women. Our data support earlier findings of an increase in risk of endometrial cancer with duration of use of fertility drugs. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source


Aim. The purspose of this research was to show the translation and linguistic validation of the PedsQL™ 4.0 Generic Core Infant Scales Parents Report for Infants (ages 13-24 months) from its original English version to Italian language. Methods. The linguistic validation consists in three steps: a) different forward translations from the original US English instrument to Italian; this step includes the drawing of a "reconciliation" version (version 1); b) backward translations from the Italian reconciliation version to US English; c) patient testing: the second version of the questionnaire (obtained after the backward translations) has to be tested on a panel of a minimmum of 5 respondents, throughout cognitive interviewing methodology, in order to obtain the final italian version of the PedsQL™ Parents Report for Infants (ages 13-24 months). In this report we summarize the third step of this process. To study the content validity, the applicability and comprehension of our questionnarie traslation, we tested it through a qualitative methodology in a sample of parents whose children were hospitalized in Bambino Gesù Children's Hospital with two different kinds of interview: 4 parents responded to the questions posed through a "thinkaloud interview" and 3 parents responded to the questionnaire and to a "respondent debriefing" interview. Results and conclusion. We modified the main question of each section and also one of the possible answer in order to maintain the Italian traslation that appeared in others PedsQL™. We did not modify the questions of each section because respondents expressed that are clearly comprehensible and easy to understand. Source

Iron refractory iron deficiency anemia (IRIDA) is a rare hereditary disease caused by mutations in TMPRSS6 gene encoding Matriptase-2, a negative regulator of hepcidin transcription. Up to now, 53 IRIDA patients from 35 families with different ethnic origins have been reported and 41 TMPRSS6 mutations have been identified. TMPRSS6 polymorphisms are more frequent than mutations, and have been associated with variation in iron and hematologic parameters. Our study evaluated their presence in 113 subjects with iron deficiency anemia (IDA) partially responsive to oral iron therapy and in 50 healthy blood donors. Thalassemic trait was diagnosed in 38 patients. Sequencing analysis of TMPRSS6 gene revealed that the frequency of several polymorphisms was markedly different between IDA subjects and controls. In particular, the V736A TMPRSS6 polymorphism was associated to moderately lower hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin levels, and in thalassemia carriers with marked anemia and microcytosis. A new variant-H448R- and two uncommon polymorphisms -A719T and V795I- were also identified. These results indicate that TMPRSS6 polymorphisms are more frequent in subjects with persistent IDA than in healthy controls, and in thalassemia carriers V736A variant may account for lower hemoglobin and MCV levels. Further studies in larger court of patients are necessary to identify potential haplotypes and polymorphisms responsible for low response to oral iron treatment and may be useful for planning a correct iron supplementation. © 2014 Wiley Periodicals, Inc.

Computer-aided diagnosis (CAD) has been extensively reported to increase sensitivity by about 10% when added to a single reading while increasing recall rate by 12%, and its current use can be safely recommended in clinical practice. CAD has been suggested as a possible alternative to conventional double reading in screening. Uncontrolled comparison is consistent and suggests that CAD is comparable to double reading in incremental cancer detection rate (CAD +10.6%, double reading +9.1%) and possibly better in recall rate (CAD +12.5%, double reading +28.8%). However, controlled studies comparing single reading + CAD to conventional double reading are not consistent and on average suggest a lower cancer detection rate (-5.1%) and a lower recall rate (-9.8%) for CAD. Scientific evidence is not sufficient for a safe recommendation of single reading + CAD as a current alternative to conventional double reading. © 2010 Springer-Verlag Italia. Source
