Résumé : International audience
The diagnosis of some infectious diseases is sometimes difficult to make and new diagnostic tools have been regularly assessed to that end. 18fluoro-deoxyglucose ((18)FDG) positron-emission tomography (PET) coupled with computed tomography (CT) is one of these new procedures. It has been evaluated for numerous infectious diseases with uneven results. A literature review allowed drawing some conclusions. First, (18)FDG-PET/CT is not currently a first-line procedure for infectious diseases. Second, it has proved useful for the evaluation of patients presenting with fever of unknown origin (FUO). Its negative predictive value is 100%: the symptoms of patients experiencing FUO with negative first-line investigations and a negative (18)FDG-PET/CT will almost always spontaneously disappear. Third, (18)FDG-PET/CT also seems to be contributive for the diagnosis of vascular prosthesis infections or osteomyelitis. Fourth, it has promising results for patients presenting with infective endocarditis, especially for secondary infectious foci, or for patients presenting with suspected infection of pacemakers or implanted defibrillator; but results are still preliminary and must be confirmed. Finally(18)FDG-PET/CT cannot be recommended yet for other infectious diseases due to lack of published data.

Résumé : International audience
After noting the forecast of a La Niña episode, associated with heavy rainfall in French Guiana, we monitored the fate of wasp nests before and during the 2006 short rainy season. The population of the most abundant epiponine wasp species, Polybia bistriata, decreased dramatically during the short rainy season (60.6% of the nests disappeared) then remained low for at least 18 months. Colonies that survived moved from the shelter of large, low leaves (a situation well adapted to the previous dry season) of the most frequent substrate tree, Clusia grandiflora (Clusiaceae), to upper leaves, better ventilated and whose orientation provides good protection from the rain. Therefore, the possibility of moving the nest higher during the first rains following the dry season seems very adaptive as colonies that do not do so are eliminated during the La Niña years, whose frequency will increase with global climate change.

Résumé : International audience
Objectifs Aucun consensus n’existe concernant la prise en charge des pneumothorax spontanés de grande abondance. Les recommandations actuelles proposent soit une exsufflation à l’aiguille, soit un drainage thoracique, la plupart des patients étant hospitalisés. Nous avons voulu tester l’efficacité d’une prise en charge ambulatoire des pneumothorax par cathéters de petit calibre dit en « queue de cochon ». Méthodes De février 2007 à janvier 2011, tous les pneumothorax spontanés primaires et secondaires de grande abondance reçus à l’hôpital de Lorient ont été pris en charge par drainage via un cathéter de petit calibre associé à une valve anti-retour. Les patients rentraient immédiatement à domicile et étaient par la suite évalués tous les deux jours selon un algorithme précis. Résultats Sur 132 pneumothorax consécutifs (110 spontanés primaires, 22 secondaires), 103 ont été exclusivement traités en ambulatoire avec un retour complet à la paroi thoracique à j2 ou j4, ce qui représente un succès de l’ambulatoire à 78 %. La durée moyenne de drainage était de 3,4 jours. Sept patients ont été initialement hospitalisés, mais sont rapidement rentrés à domicile et ont été totalement guéris à j2 ou j4, ramenant le taux de succès à 83 %. L’usage d’antalgique était faible. Le taux de récidive à un an était de 26 %. En cas de succès, cette prise en charge est potentiellement économique avec un coût moyen estimé à 926 comprenant 2 consultations et une radiographie thoracique, en comparaison aux 4276 estimés si le patient était hospitalisé avec mise en place d’un drain thoracique pendant 4 jours. Conclusion La prise en charge ambulatoire des pneumothorax spontanés de grande abondance par cathéters de type « queue de cochon » associés à une valve anti-retour peut être considérée comme un traitement de première intention raisonnable. En comparaison avec d’autres études, notre protocole ne nécessite pas d’hospitalisation et est économique

Résumé : International audience
Although they are famous among Earth scientists, the Lherz peridotites are exposed within geological formations of the North Pyrenean Zone (NPZ) still lacking detailed investigations. Our study focuses on the metasediments of the Aulus basin hosting the Lherz peridotite body and associated ultramafic fragments of smaller size. The new data set comprises of structural analysis and detailed geological mapping of the massive Mesozoic marbles that form the prerift sequence typical of the NPZ and of the ultramafic-rich clastic breccia formations surrounding the peridotite bodies. The massive marbles display an evolution from hot and ductile to cold and brittle deformation, indicative of an exhumation process ending with the sedimentary reworking of both the deformed Mesozoic metasediments and the exhumed ultramafic rocks. Crystal Preferred Orientations (CPO) measured in the marbles support a deformation mechanism by dislocation creep of calcite, which is dominant between 400 8C and 600 8C; these deformation temperatures are within the range determined earlier by Clerc et al. (2015), using RSCM (Raman Spectroscopy of Carbonaceous Material) geothermometry. As a consequence, we better describe the transition from ductile to brittle deformation in the prerift marbles and clarify the origin of the syn-rift breccias. Due to continuous exhumation along detachments' faults, the brecciated metamorphic carbonates of the prerift NPZ sedimentary cover were passively uplifted towards shallower levels and progressively unroofed, while transported passively on the back of the exhumed ultramafic footwall. These results are consistent with the recent interpretations of the North Pyrenean peridotites as remnants of subcontinental mantle rocks exhumed within the pre-Pyrenean rift system. We emphasize the importance of tectonic decoupling between the Mesozoic sedimentary cover and the Palaeozoic basement, which leads to the juxtaposition of metamorphosed and deformed Mesozoic Please cite this article in press as: Lagabrielle Y, et al.

Résumé : National audience
OBJECTIVES: Medical tools to determine the imminence of unplanned out-of-hospital birth have not been validated. The main goal of this study was to analyze assessments of the imminence of these deliveries, by methods such as the Manilas score and the need to push. PATIENTS AND METHODS: All calls made to the Emergency Medical Aid Service in Guadeloupe concerning risks of unplanned delivery between January 1st and June 30th 2011 were reviewed retrospectively, and 69 of the 85 cases cared for by the hospital mobile emergency unit were included. RESULTS: Risks of unplanned out-of-hospital deliveries represented 1.9% of the calls during the study period. The Malinas score was used for dispatching in only 13% and was not used for intervention in any case. It was estimated that the need-to-push feeling was used for 58% (dispatching) and 54.5% (intervention) of patients. Its sensitivity, specificity and predictive values were higher than those of the Malinas score in dispatching and substantially higher in intervention. CONCLUSION: These results argue for the development of tools for estimating the imminence of unplanned delivery. Such tools should be applicable in extra-hospital emergency situations to ensure their use in practice.

Résumé : International audience
This observation perfectly illustrates the main epidemiological, clinical and biological peculiarities of this parasitic disease. Particularly, as it concerns a tourist who travelled across Africa for a short period of time it is possible to assess the time of exposure to infecting mosquito bites, the maturation period of time as well as the time of clinical incubation. On the other hand the value of the immunological techniques to make the diagnosis of loaiasis as well as the difficulties to treat this affection are stressed upon.

AIM: To describe the amount of medical and paramedical involvement in a sample of Breton children with cerebral palsy as a function of the Gross Motor Function Classification System (GMFCS). MATERIALS AND METHODS: This is a transversal descriptive study. All children with cerebral palsy in Brittany were eligible. Parents who accepted to participate were asked to fill in a questionnaire regarding medical and paramedical involvement with their child. RESULTS: One hundred and thirty-three parents participated. 40.6% of the children were level I on the GMFCS, 20.3% II, 12.03% III, 13.53% IV and 13.53% were level V. Thirty-nine percent of the children took at least one medication (of which 43% were antiepileptic drugs). 33.1% of the children had received at least one injection of botulinum toxin within the year. Forty-four percent used a mobility aid. Eighty-five percent of the children had at least one orthotic device, most often a night ankle-foot orthosis. The median number of rehabilitation sessions per week was 3.85 [0.5-11.5]. The frequency and type of sessions were mostly related to the GMFCS level. CONCLUSION: This study reports high levels of medical and paramedical involvement. Studies must attempt to define optimal practice.

Résumé : La présente revue a pour but de faire état des travaux traitant de la relation entre la musique et la performance sportive à des efforts de courte et de longue durées.L’analyse de la littérature souligne clairement les bénéfices de la musique sur les performances motrices et/ou sportives. La plupart des études révèle que la musique écoutée avant, pendant ou après l’effort influence les processus psychophysiologiques de la performance et/ou la performance elle-même à des efforts de courte ou de longue durées. La littérature révèle toute la complexité de la relation musique–performance dans la mesure où cette relation implique un grand nombre de facteurs, de type interne, situationnel et contextuel, entrant en interaction complexe, affectant ainsi les sphères affective, cognitive, motivationnelle, physiologique et comportementale des individus.Si la littérature relate un nombre considérable de travaux confortant l’hypothèse selon laquelle la musique améliore la performance, la compréhension des mécanismes psychophysiologiques sous-tendant la relation musique–performance reste encore limitée. L’adoption de la perspective complexe et dynamique proposée dans ce présent travail pourrait permettre de faire la lumière sur les mécanismes sous-tendant cette relation.Bien que l’examen de la relation musique–performance réponde à un objectif essentiellement théorique, la compréhension de ses mécanismes devrait permettre de développer des stratégies pouvant améliorer la performance sportive.

Résumé : International audience
Depuis quelques années, l'expression " perturbateur endocrinien " fait partie du langage commun scientifique et populaire. Cette expression fait référence aux substances chimiques, d'origine anthropique ou naturelle, susceptibles de générer des effets nocifs sur la santé humaine et animale par le biais de leurs propriétés hormonales. Mais la définition même des perturbateurs endocriniens fait encore l'objet de discussions. De très nombreux processus physiologiques font intervenir des systèmes de communication hormonale. Les substances chimiques pouvant interférer avec ces systèmes sont très diverses. Les systèmes endocriniens sont multiples. De ce fait, les conséquences sanitaires potentielles peuvent être très variées. À ce jour et à quelques rares exceptions, les conséquences délétères des expositions aux perturbateurs endocriniens sur la santé humaine n'ont pas été prouvées. La science qui s'est développée autour des perturbateurs endocriniens présente des contours particulièrement larges et flous. Cette science en pleine évolution est donc soumise à de nombreuses incertitudes, Cependant, sur le plan strictement scientifique, c'est une opportunité d'accroître les connaissances du fonctionnement des systèmes endocriniens et de leurs pathologies. Sur un plan sociétal, c'est l'occasion de s'interroger sur les activités de l'homme et sur ses conséquences néfastes sur sa santé, son devenir et son environnement.

Central Africa hosts the world's second largest tropical forest after the Amazonian basin. However, as compared to its Amazonian counterpart, the Central Africa forests receive much less rain (∼1500 mm/year in mean spread over two rainy seasons in March-May and September-November, and two dry seasons). They also experience a slower deforestation rate, so that the main threat for the next decades might come from climate variations. Nonetheless, their response to the annual cycle of solar radiation and rainfall/clouds is still poorly known. Analysing high resolution remote sensing data of Enhanced Vegetation Index, rainfall, cloudiness, and solar radiation for a target region located between 0 and 5°N and 12–19°E, we explore the climatic drivers of the forests greenness mean annual cycle. Three main points emerge; first, the diurnal cycle is a key-scale for understanding the mean annual cycles of rainfall and incoming solar radiation at surface, then how climate shapes the greenness mean annual evolution; second, neither the two dry seasons nor the two rainy seasons resemble each other in terms of cloud cover, solar radiation and rainfall, and their links with greenness levels; third, whereas the first rainy season (March-May) appears optimal for greenness especially because of favorable light conditions, water availability is the main controlling factor during the main dry season and at the start of the first vegetative season (February). Regarding the little dry season (mid-June-mid-August) and the second rainy season (September-October), light availability might be the main limiting factor. These findings pave the way for further studies of the climate interannual variability and change impacts on the Central Africa forests, taking into account time-scale interactions.

Résumé : International audience
Introduction: Hydroxyurea is an antimetabolite widely used in the treatment of myeloproliferative diseases. Usual side effects are mainly hematological, gastrointestinal, neurological disorders and induced-fevers. More rarely, hydroxyurea-induced pneumonitis are reported. Case report: We report a case of a patient treated for polycythemia vera. She was admitted 20 days after introduction of hydroxyurea for a high fever, productive cough and clear sputum associated with nausea. Chest CT-scan found diffuse bilateral ground-glass opacities. The microbiological investigations were negative. Symptoms disappeared few days after discontinuation of treatment. Its reintroduction led to recurrence of symptoms. Conclusion: This additional case completes the 15 cases of hydroxyurea-induced pneumonitis described in the literature. Two forms of this disease seem to exist: an acute form with fever occurring in the month following introduction of hydroxyurea; and a chronic form without fever. Even if it is uncommon, pulmonologists should be aware of this complication.

Résumé : International audience
The only symbiotic Mediterranean gorgonian, Eunicella singularis, has faced several mortality events connected to abnormal high temperatures. Since thermotolerance data remain scarce, heat-induced necrosis was monitored in aquarium by morphometric analysis. Gorgonian tips were sampled at two sites: Medes (Spain) and Riou (France) Islands, and at two depths: 15 m and-35 m. Although coming from contrasting thermal regimes, seawater above 28 degrees C led to rapid and complete tissue necrosis for all four populations. However, at 27 degrees C, the time length leading to 50% tissue necrosis allowed us to classify samples within three classes of thermal sensitivity. Irrespectively of the depth, Medes specimens were either very sensitive or resistant, while Riou fragments presented a medium sensitivity. Microsatellite analysis revealed that host and symbiont were genetically differentiated between sites, but not between depths. Finally, these genetic differentiations were not directly correlated to a specific thermal sensitivity whose molecular bases remain to be discovered.

Résumé : International audience
The two experiments reported in the present paper concern (i) the differential imagery value of French and Creole and (ii) the influence of language on the recall of sequences of patterned movements in a bilingual population. Creole words were obtained a higher imagery value than French words, certainly because Creole is an oral and vernacular language. Motor recall scores were better when the sequence was presented in Creole compared to French. The generation of visual images by Creole would facilitate the memorization and recall of new sequences of movements. The effect of language on imagery value of words and motor recall among bilingual French–Creole subjects was discussed in terms of nature of information encoding in each language.
Les deux expérimentations relatées dans cet article évaluent la valeur d'imagerie de mots et le rappel moteur d'enchaînements auprès de bilingues français–créole en faisant varier la langue de présentation. Les mots en créole, supposés susciter plus facilement des images mentales visuelles, car le créole est une langue orale et vernaculaire, ont effectivement obtenu une cote plus élevée que les mots français sur l'échelle de valeur d'imagerie. L'évocation d'images visuelles facilitant la mémo-risation et la planification de séquences de mouvements, les performances de rappel obtenues à partir des consignes en créole ont été supérieures à celles obtenues en français. Les effets de la langue de présentation sur la valeur d'imagerie des mots et le rappel moteur d'enchaînements de morphocinè-ses auprès des participants bilingues sont discutés en termes de nature d'encodage de l'information verbale dans chacune des langues.
