[Evaluation of medical information systems as a mean of identification of incident cases of colorectal cancer].

Background: Cancer registries are a reliable source of data to estimate national cancer incidence rates, but they are not always available in all regions. This study assessed the value of medical information systems (PMSI) to identify incident cases of colorectal cancer

Methods: Two algorithms were elaborated to identify these incident cases in the PMSI database. The first algorithm was based on diagnosis and medical procedure codes and the second algorithm was based exclusively on diagnoses and the absence of diagnoses over the last five years.

Comparison of British and French expatriate doctors' characteristics and motivations.

Objective: The aim of this study was to analyse the migration of doctors between the UK and France, in an attempt to identify the reasons for these migrations.

Design: This was a cross-sectional study conducted using a self-completed questionnaire.

Setting: The questionnaire was sent to all British doctors practising in France and to all French doctors practising in the UK.

Chronic viral hepatitis and risk of lymphoid malignancies: a retrospective twelve-year population-based cohort study in Côte d'Or, France.

Background: The association between hepatitis C infection and lymphoid malignancies is still a matter of debate. The hypothesis of a relationship between hepatitis B and lymphoid neoplasms is more recent and has been far less thoroughly explored.

Aim: The aim of this study was to evaluate the association between hepatitis C and B infections and B cell non-Hodgkin and Hodgkin lymphomas.

Environmental justice in a French industrial region: are polluting industrial facilities equally distributed?

Recent studies have suggested that minority or deprived groups are subject to the additional burden of a polluted living environment. Our goal is to determine whether such environmental inequalities occur in France's leading industrial region, using detailed socio-economic data and advanced Bayesian methods. Associations between proximity to hazardous facilities (i.

Active trachoma among children in Mali: Clustering and environmental risk factors.

Background: Active trachoma is not uniformly distributed in endemic areas, and local environmental factors influencing its prevalence are not yet adequately understood. Determining whether clustering is a consistent phenomenon may help predict likely modes of transmission and help to determine the appropriate level at which to target control interventions. The aims of this study were, therefore, to disentangle the relative importance of clustering at different levels and to assess the respective role of individual, socio-demographic, and environmental factors on active trachoma prevalence among children in Mali.

Dioxin emissions from a municipal solid waste incinerator and risk of invasive breast cancer: a population-based case-control study with GIS-derived exposure.

Background: To date, few epidemiologic studies have examined the relationship between environmental PCDD/F exposure and breast cancer in human populations. Dioxin emissions from municipal solid waste incinerators (MSWIs) are one of the major sources of environmental dioxins and are therefore an exposure source of public concern. The purpose of this study was to examine the association between dioxins emitted from a polluting MSWI and invasive breast cancer risk among women residing in the area under direct influence of the facility.
