Résumé : National audience
The most recent data on prevalence of chronic hepatitis B and C in the French Overseas Territories (FOT) show great variability among these territories with a prevalence rising from 0.46 to 3.4% for HBs Antigen and from 0.02 to 0.67%for anti HCV antibodies. The modes of transmission rely mainly for HBV on sexual or materno-fetal exposure, especially among people from non-French border endemic areas, and for HCV on blood or nosocomial route. Good adhesion of the treating physicians and pediatricians to vaccination has significantly reduced the prevalence of HBV in the ten past years, with an estimated coverage of 75 to 85%depending on the territories. Although there is still a high prevalence of HBV in some FOT, the screening policy and management are based on those carried out inmetropolitan France, which seems insufficient and inadequate to the situation of these territories. Regarding the therapeutic management of HCV, the means attributed to FOT have been identical to those of metropolitan France but the small number of specialist practitioners and remoteness contributed to provision of new molecules later in certain territories. Medical pluridisciplinary sessions have been implemented and based on the universitary or regional hospitals. Copyright © 2017 John Libbey Eurotext.

Résumé : International audience
The diversity of chemicals used in hospitals (detergents-disinfectants, alcohol-based hand sanitizers, drugs, etc.) and recent developments in indoor air quality regulation of public access buildings require a better understanding of chemical risks in this particular environment. We developed a methodology for semi-quantitative chemical risk assessments in this environment to prioritize inhalation risks by sector and chemical. This methodology is based on a similar approach in the workplace that defines classes of exposures and of hazards. Their combination produces a risk matrix. Four criteria were used to determine the exposure classes: quantity and frequency of the chemical's use, volatility (vapor pressure), and the type of collective protective equipment associated with each area. The hazard class is also derived from four criteria: classification as carcinogenic, mutagenic, or toxic to reproduction, the existence of a toxicity reference value, occupational exposure limit values, and risk phrases (official risk descriptions, on labels, data sheets, etc). This methodology was tested in the Rennes University Hospital (Rennes, France) in five different hospital areas, with a specific survey undertaken to collect data about chemicals in each area. The results show the spatial specificity of chemical risks. Among the various sites analysed, the chemical risks of two require priority attention: the parasitology-mycology laboratory and patients' rooms. Because of their wide use in the hospital and the volatility of some of their components (alcohols), detergents-disinfectants contribute to increasing risk levels in all areas. The model is therefore discriminatory in terms of areas and substances.

Résumé : How may fish domestication participate in sustainable development of aquaculture? The development of fish farming currently compensates for the stagnation of fishery catches while the market demand continues to increase. The development of fish farming relies on an active diversification of farmed fish species. A diversification based on the farming of native species could reduce the environmental impact of fish culture and could better fit to needs of local markets. Such development could also favour a more integrated local economy. In this context, the building of a generic approach for multi-species domestication is required to optimise the use of the technical and financial means available for fish culture diversification.

Résumé : International audience
Environmental health risk assessment is commonly used in France for risk management purposes. The Methodology section of the "Société française de santé environnement" (French Society for Environmental Health) seeks to improve the utility and implementation of risk assessment in France. An initial operational objective is to make a list of short-, intermediate- and long-term improvements. This inventory is based in part on the experience and expertise of society members in this area and in part on their analysis of "Science and Decisions: Advancing Risk Assessment" (National Research Council 2009). In this paper, the Society recommends modifications in the indications for and use of risk assessments, during each of the four stages of the process: hazard identification and dose-response assessment, exposure assessment, risk characterization, and results interpretation. Some may be implemented now, while others need consensus building or research because of gaps in knowledge. Environmental health risk assessment must be understood as a decision tool for risk management in situations of uncertainly. Thus, appropriate linkage is required between decision making and assessment, and between the methods and the expected results.
L'évaluation des risques sanitaires est fréquemment utilisée en France dans les processus de décision en santé environnementale. La section " Méthodologie d'évaluation des risques sanitaires " de la Société française de santé environnement (SFSE) s'est donnée pour objectif de proposer des éléments de réflexion et des outils méthodologiques en vue d'améliorer l'utilité et les pratiques de l'évaluation des risques sanitaires. Un premier objectif opérationnel est l'inventaire des améliorations possibles à court, moyen et long termes à apporter à la démarche et à son utilisation. Ce travail s'est fondé, d'une part, sur la pratique et l'expertise des membres de la section, et, d'autre part, sur une lecture critique du rapport " Science and Decisions : Advancing Risk Assessment " publié en 2009 par le National Research Council et portant également sur les évolutions de la démarche. Dans cet article, la section restitue les conclusions de cet inventaire critique et propose un certain nombre d'améliorations en termes d'indications et d'utilisations de l'évaluation des risques sanitaires pour chacune des quatre étapes : identification des dangers et relation dose-réponse ; évaluation de l'exposition ; caractérisation des risques ; et interprétation des résultats. Certaines recommandations peuvent être mises en oeuvre immédiatement ; d'autres, en préalable à leur mise en oeuvre, nécessitent un consensus ou encore de la recherche car les connaissances manquent. En conclusion, la section insiste sur le fait que l'évaluation des risques sanitaires doit être comprise comme une aide à la décision en situation d'incertitude ; l'articulation entre le contexte décisionnel et l'évaluation, sa méthodologie et les résultats attendus est donc primordiale.

Résumé : International audience
In mainland France, as in most Western countries, prostate cancer is the most frequent cancer in men. However, the incidence of this cancer is highly variable, depending on the region of the world. This variability is largely accounted for by differences in access to care, but also by environmental conditions and the ethnogeographic origins of the populations. The French West Indies--the archipelago of Guadeloupe and the island of Martinique--are unique in terms of their geography, environment and the lifestyle and origins of their populations. We report the incidence and mortality rates for prostate cancer in the French West Indies and also provide the first description of the major clinical and anatomical characteristics of this disease in this region.

Résumé : International audience
Chemical risk assessment is a tool used in decision-making processes concerning situations of scientific uncertainty. Approaches to risk assessment in occupational and environmental health share the same objective of risk prevention. Nevertheless, the methods for both differ depending on whether the goal is to enforce regulations or conduct expert assessments and studies. These differences are stronger in occupational health, for which regulations require risk assessments at the work station, to classify and prioritize exposure situations to implement occupational risk prevention strategies. Risk assessment thus has somewhat different meanings in occupational and environmental health. This article attempts to clarify the different terms used in the different contexts and to describe the similarities and differences of the two approaches.

Résumé : International audience
French toxicological reference values (VTR) and French occupational exposure limit values (VLEP) are indicators that are widely used in risk assessment for, respectively, human and occupational health. Neither value can replace the other. However, the information obtained for one can be very useful for the other. We propose to clarify the fundamental differences and similarities between these two values. To achieve this, we review first their history and then the methods used to derive them; we conclude by proposing some improvements to harmonize them. A case study of formaldehyde illustrates our analysis.

Résumé : International audience
The principal gynaecological cancers (breast, ovary, uterus, and cervix) account for over 40% of cancers found in women worldwide. However, large differences exist, in both their incidence and geographical distribution. The French West Indies, through their location, environment, socio-economic development, lifestyle, nutrition and the origins of their populations, constitute territories with a very particular character in the heart of the Caribbean. These characteristics have an impact on public health and can affect the incidence of tumours. We report for the first time the incidence of these major gynaecological cancers in Guadeloupe. Breast, ovary and uterine cancers have lower incidences in Guadeloupe than in mainland France. By contrast, cervical cancer is more frequent in Guadeloupe than in mainland France. The mortality rates associated with breast cancer, ovary and uterine cancer are also lower in Guadeloupe than in mainland France, whereas the opposite pattern is observed for cervical cancer. These observations may be accounted for in part by a difference in the prevalence of established or suspected risk factors for each of these types of cancer.

Résumé : International audience
Prostate cancer is the most frequent cancer affecting men in most Western countries. Certain risk factors have been identified (age, family history, ethnic origin), but the aetiology of this cancer remains largely unknown. However, a role for environmental factors is strongly suspected. Questions have been raised concerning the role of the chemical substances generated by human activities in the occurrence of this disease. Diverse studies have consistently demonstrated a higher risk of prostate cancer in agricultural populations than in the general population. The hypothesis that this higher risk is linked to the use of pesticides has been tested in a number of studies, mostly in North America and Europe. However, to date, with a few possible exceptions, it has been impossible to demonstrate a significant association between exposure to pesticides or a chemical family of pesticides and prostate cancer. In the face of these uncertainties, rigorous studies are required, with objective measurements of exposure, taking into account confounding factors and individual risk factors, making it possible to assess gene-environment interactions.

Résumé : The new sustainable development data repository requires new analysis grids, in particular for factors accounted for in productive system typologies. This paper, based on the aquaculture example, analyses the diversity in aquaculture systems with respect to sustainable development. Various typologies are obtained by evaluating structural and functional approaches integrating variables related to production and regulation systems and to the territorial insertion of fish farms. Categories have been defined on a scale based on a set of five sites, which are representative of a wider range of aquaculture systems. Use of these categories goes beyond the local typologies and prepares a generic meta-typology classification for the systems. This generic classification is then compared to the views of sustainable development held by the fish farmers working on the various types of farms.
