ABSTRACT
We report here an atypical case of acute sacroiliitis caused by Erysipelothrix rhusiopathiae revealing tricuspid endocarditis in a 53-year-old woman without medical history. She was admitted to Cayenne hospital because of intense right hip and thigh pain, associated with fever. A right sacroiliitis was visible on the computed tomography (CT) scan, confirmed on MRI. Transesophageal echocardiography revealed a large mobile tricuspid vegetation. Blood cultures were positive for E. rhusiopathiae. CT scan showed pulmonary alveolar opacities, consistent with septic emboli. Clinical improvement was obtained under ceftriaxone followed by ciprofloxacin for 6 weeks of treatment. We present a review of bone and joint infections caused by E. rhusiopathiae. So far, not a single case has been reported in Latin America.

The health of migrants is a complex issue in public health. In French Guyana, as elsewhere, globalization, through migrants in particular, has transformed the care of diseases previously geographically distant. In this context, the borders now concern the entire territory and not just the peripheries. These borders contribute to the aggravation of the migrants health determinants through the complex and sometimes risky paths that they generate. Transboundary areas are also areas of high vulnerability. However, these cross-border spaces and routes can also constitute health resources, in the original interfaces that they can produce in terms of cooperation promoting shared screening and monitoring programs.
FRONTIÈRES : PROBLÈMES OU RESSOURCES EN SANTÉ POUR LES MIGRANTS ? EXEMPLE DE LA GUYANE. La santé des migrants représente un enjeu complexe en santé publique. En Guyane comme ailleurs, la globalisation, au travers des migrants notamment, a transformé les prises en charge sanitaires de pathologies qui étaient jusqu'alors géographiquement bien éloignées. Dans ce contexte, les frontières intéressent dorénavant l'ensemble du territoire et non plus seulement les périphéries. Ces frontières participent à l'aggravation des déterminants en santé des migrants du fait des parcours complexes et parfois risqués qu'elles engendrent. Les espaces transfrontaliers représentent également des zones de grande vulnérabilité. Cependant, ces espaces et parcours transfrontaliers peuvent aussi constituer des ressources en santé dans les interfaces originales qu'elles peuvent produire en termes de coopération promouvant des programmes partagés de dépistage et de suivi.

A 40-year-old soldier in Guyana consulted at the end of December for skin lesions that had been developing for several weeks after he was lost overnight in the equatorial forest, near the village of Saul. He was bitten by numerous mosquitoes during the night and as he crossed marshy areas. When he arrived at the clinic he had 23 leishmaniasis sites visible.

Sponges collected on the Guyana Shelf, predominantly in Suriname offshore waters, by Dutch HMS 'Snellius' O.C.P.S. 1966, HMS 'Luymes' O.C.P.S. II 1969, and HMS 'Luymes' Guyana Shelf 1970 expeditions are described in this study. Sponges were obtained by trawling, dredging or grabbing on sandy, muddy, shelly, and fossil reef bottoms at 88 stations between 19 and 681 m depth. A total of 351 samples were identified to species level, each consisting of one or more specimens of a given species from each individual station (together comprising 547 individuals and fragments). The collection yielded 119 species together belonging to all sponge classes, but in large majority are Demospongiae. All species are identified to species level, occasionally tentatively, and all are described and illustrated. A new subgenus is proposed, Tedania (Stylotedania) subgen. nov. and a previously synonymized genus, Tylosigma Topsent, 1894 is revived. Thirtysix species were found to be new to science, excluding the first Central West Atlantic record of the genus Halicnemia, not named at the species level because of lack of sufficient material. The new species erected are, in alphabetical order: Amphoriscus ancora sp. nov., Biemna rhabdotylostylota sp. nov., Callyspongia (Callyspongia) scutica sp. nov., Chelonaplysilla americana sp. nov., Cladocroce guyanensis sp. nov., Clathria (Axosuberites) riosae sp. nov., Clathria (Clathria) gomezae sp. nov., Clathria (Microciona) snelliusae sp. nov., Clathria (Thalysias) complanata sp. nov., Clathria (Thalysias) zeai sp. nov., Coelosphaera (Coelosphaera) lissodendoryxoides sp. nov., Craniella crustocorticata sp. nov., Diplastrella spirastrelloides sp. nov., Epipolasis tubulata sp. nov., Erylus rhabdocoronatus sp. nov., Erylus surinamensis sp. nov., Geodia pocillum sp. nov., Geodia sulcata sp. nov., Hemiasterella camelus sp. nov., Hymedesmia (Stylopus) alcoladoi sp. nov., Hymenancora cristoboi sp. nov., Penares sineastra sp. nov., Hymerhabdia kobluki sp. nov., Leucosolenia salpinx sp. nov., Petrosia (Strongylophora) devoogdae sp. nov., Placospongia ruetzleri sp. nov., Pyloderma tropicale sp. nov., Raspailia (Parasyringella) thamnopilosa sp. nov., Raspailia (Raspailia) johnhooperi sp. nov., Sphaerotylus bouryesnaultae sp. nov., Spirastrella erylicola sp. nov., Stelletta vervoorti sp. nov., Suberites crispolobatus sp. nov., Tedania (Stylotedania) folium subgen. nov. sp. nov., Timea tylasterina sp. nov., and Tylosigma ostreicola sp. nov. Two new combinations are proposed: Amphimedon nanaspiculata (Hartman, 1955) comb. nov. and Oceanapia ascidia (Schmidt, 1870) comb. nov. In addition, for two preoccupied combinations, new names, Coelosphaera (Coelosphaera) barbadensis nom. nov. and Hymedesmia (Hymedesmia) rowi nom. nov., are erected. The spatial distribution of the collected specimens over the Guyana Shelf was traced and the results were compared with existing information on bottom conditions. There was a convincing correlation between the location of fossil reefs and other hard substrates such as shell ridges with peaks in the occurrence of species diversity and specimen numbers. Stations made on sand and mud bottoms away from these zones of hard substrates were generally poor in species, but some were found to be rich in individuals of specialized soft bottom dwellers such as Tetilla pentatriaena, Tribrachium schmidtii, Fangophilina submersa, and Oceanapia species. The species composition of the Guyana Shelf was compared with that of neighbouring regions of the Caribbean and from North and East Brazil (Díaz in Miloslavich et al. 2010; Muricy et al. 2011). About 35% of the species encountered are widespread in the Central West Atlantic, occurring both to the north and to the south. Indications that the Guyana Shelf sponge fauna is clearly transitional are southernmost occurrences for Caribbean species (about 30%), and northernmost occurrences of Brazilian species (13%), with a high proportion (25%) of new species, which may be expected to have distributions extending to the Caribbean, to Brazil or both regions.

The Amazon Basin occupies a vast portion of northern South America and contains some of the highest species richness in the world. The northern Brazilian state of Amapá is delimited by the Amazonas River to the south, the Oyapock River to the northern boundary with French Guyana, and the Atlantic northeastern coast to Amazon estuary. Despite several expeditions to the Amazon in recent decades, little is known about the freshwater ichthyofauna from Amapá, with records limited to local inventories and species descriptions. This paper presents a compilation of the freshwater fish diversity sampled in fifteen sites covering two major Amapá ecoregions during the dry season of 2015. 120 species representing eight orders and 40 families are reported upon in this work. Eight species appear for the first time in the Brazilian territory providing new information for future conservation status evaluations.
ABSTRACT
OBJECTIVE: To describe the epidemiological, clinical and prognostic factors of placental abruption and fetal death in utero and to investigate possible risk factors for their occurrence. PATIENTS AND METHODS: Observational retrospective study including the women having presented a placental abruption between January 2001 and January 2012, in a IIB maternity. Women's sociodemographic characteristics, clinical symptoms and the method used to detect placental abruption were collected. Patient data of those whose pregnancy resulted in fetal death were compared to those with more favorable outcomes. RESULTS: There were 171 cases of placental abruption among 21,913 patients having delivered, which represents a 0.78% incidence. Diagnosis was rarely based on clinical data (30%). The rate of fetal death in utero represented 25% of the pregnancy's outcomes. A history of fetal death in utero increased the risk of placental abruption (P<0.001). This complication was more frequent for patients who did not have pregnancy monitoring (P=0.054) and before 37 weeks of amenorrhoea (P=0.005). CONCLUSION: Placental abruption is an important cause of perinatal mortality and maternal morbidity. Among the observed risk factors, only regular pregnancy monitoring can be an easy way to prevent these complications.

A tropical forest is a hostile environment for humans. The military physician supporting these immersion activities must cope with varied clinical situations with limited resources to reduce operational unavailability. This article reports a prospective cross-sectional epidemiologic study conducted from January to May 2012, observing the daily activity at sick call during the rainy season at the tropical forest training center (CEFE) advanced jungle commando training, located in French Guyana. The aim was to observe the distribution of traumatic injuries and specific diseases in this tropical environment. In all, 9,221 army staff members participated in the training (mean age: 30.8 years) during the 120-day study period. There were 486 medical visits, for a mean daily incidence of 5.3% (trainees: 83.8%, trainers: 16.5%). Skin lesions were most frequent (39%), principally irritative dermatitis and skin maceration (moisture/dressing associated dermatitis). A third (34%) of these conditions were due to trauma, mainly limb contusions and ligament injuries. Tropical diseases accounted for 3% of the reasons for consultation, with rare problems related to equatorial fauna or flora. The remaining conditions (24%) were not specific to the environment or activity. Operational attrition averaged five days. Removal from the training course was necessary in 13.8% of the cases. In an isolated area with a demanding environment , edical practice in a tropical forest requires health prevention actions and close medical follow-up. The permanent presence of a physician provides both care and expertise and is an important asset for both trainees and trainers.
