Andrée-Rosemon Hospital (French: Centre Hospitalier de Cayenne Andrée Rosemon) is a hospital in Cayenne, French Guiana. With 747 beds, it is the largest and only full-service hospital in the overseas department and region of French Guiana.The hospital is located in the Madeleine district of Cayenne. In 1974 a central kitchen and laundry opened at the site. In 1977 a psychiatric hospital was added, and in 1992 the area was further extended with a hospital as a replacement for the Saint-Denis hospital which has become a nursing training institute. In 2007 a nursing home (EHPAD) was added to the terrain. The hospital was named after Andrée Rosemon, the first general nurse of the Cayenne hospital center.The hospital manages 18 prevention and care centres across the region and has as of 2017, 250 doctors and a total staff of 2,175 employees. The intensive care capacity as of 10 April 2020 is 38 beds.
BACKGROUND:Intestinal parasitic infections are common in tropical settings and may influence immune regulation, allergic responses, and respiratory health. In children with sickle cell disease (SCD), respiratory morbidity is multifactorial, and the contribution of intestinal parasites remains uncertain. This study assessed whether documented intestinal parasitic infections, particularly helminth infections, were associated with asthma-like respiratory phenotypes and clinical morbidity in children with SCD in French Guiana. METHODS:We conducted a multicenter cross-sectional analysis of children and adolescents younger than 18 years with confirmed SCD who were being followed by the pediatric SCD centers of Saint-Laurent-du-Maroni, Cayenne, and Kourou between January 2022 and December 2025. Clinical, respiratory, and parasitological data were extracted from routine-care medical records. Intestinal parasitic infection was defined as at least one documented stool parasitology result identifying Strongyloides stercoralis, hookworm, or Entamoeba histolytica, according to the variables consistently available in the database. Respiratory outcomes included physician-diagnosed asthma, bronchial obstruction, bronchodilator reversibility, and an asthma-like respiratory phenotype. RESULTS:Among 233 included children, 105 (45.1%) had at least one documented intestinal parasitic infection and 82 (35.2%) had a helminth infection. Hookworm was the most common parasite (75/233, 32.2%), followed by Entamoeba histolytica (33/233, 14.2%) and Strongyloides stercoralis (24/233, 10.3%). An asthma-like respiratory phenotype was observed in 32/105 infected children (30.5%) versus 44/128 non-infected children (34.4%). Bronchial obstruction and bronchodilator reversibility were also similar between groups. After adjustment for age, sex, genotype, hydroxyurea treatment, rural residence, site of follow-up, and environmental tobacco smoke exposure, intestinal parasitic infection was not associated with asthma-like respiratory phenotype (adjusted OR: 0.94, 95% CI: 0.51-1.72; p = 0.844), recurrent hospitalization, or history of acute chest syndrome. CONCLUSIONS:In this routine-care multicenter pediatric SCD cohort from French Guiana, intestinal parasitic infections were common but were not associated with respiratory phenotype or selected morbidity outcomes. Because testing and respiratory assessment were not systematic, these findings should be interpreted as showing that routine parasitological status alone could not identify children with respiratory morbidity. Prospective studies with standardized repeated parasitological, immunological, environmental, and respiratory assessments are needed.
Introduction L’histoplasmose américaine, causée par le champignon Histoplasma capsulatum var. capsulatum, est une infection fongique acquise par inhalation de spores, qui peut progresser vers des formes disséminées et mortelles chez les immunodéprimés. Cette maladie tropicale négligée, est la première cause d’infection opportuniste chez les patients vivant avec le VIH (PVVIH) en Guyane. L’atteinte cutanée, bien que peu fréquente, permet un diagnostic peu coûteux et rapide. Elle était en diminution pendant les années 2006–2014 concordant avec les avancées thérapeutiques de la prise en charge du VIH. Nous avons conduit une étude rétrospective des cas d’histoplasmose cutanée diagnostiqués en Guyane afin de suivre son évolution clinique et épidémiologique sur cette dernière décennie. Matériel et méthodes Étude multicentrique rétrospective incluant les cas d’histoplasmose confirmés par histologie ou culture mycologique sur biopsie cutanée en Guyane de 2015 à 2025. Résultats Au total, neuf patients présentaient une histologie cutanée positive à Histoplasma capsulatum. Tous les patients avaient moins de 60 ans, vivant en Guyane depuis plus de dix ans. Sept sur 9 étaient porteurs du VIH, avec des CD4 inférieurs à 60/mm3. Les deux autres patients avaient un lymphome et une aplasie de cause indéterminée. Cinq patients présentaient uniquement une atteinte cutanée ou muqueuse et quatre une forme disséminée avec atteinte pulmonaire ou médullaire. Les atteintes cutanées étaient très polymorphes: papules disséminées (1 cas), tableau évocateur de dermatophytose profuse (2 cas), lésions muqueuses palatines et péniennes à type d’ulcération à bord bien délimités (3 cas). Un patient présentait un sarcome de Kaposi concomitant retrouvé sur les mêmes lésions à type de papules violacées; un dernier cas présentait des lésions pseudotumorales dans le cadre d’une co-infection à HTLV-1.L’histologie cutanée était le premier test positif chez sept des neuf patients, avec des cultures sanguines positives seulement dans trois cas. Sept patients étaient traités par amphotéricine B liposomale, un par itraconazole et un patient décédait avant traitement. Cinq des neuf patients sont décédés à trois mois de complications du VIH ou de l’histoplasmose. Discussion L’incidence de l’histoplasmose cutanée chez les PVVIH semble stable malgré les avancées thérapeutiques du VIH (incidence annuelle moyenne de 0,7 par an contre 0,75 par an pendant les années 2004–2016). Le grand polymorphisme des lésions d’histoplasmose cutanée impose une bonne formation des spécialistes car elle est liée à une forme sévère et mortelle de la maladie. En effet, la peau reste l’organe le plus accessible pour confirmer le diagnostic et permet donc un traitement rapide, diminuant la mortalité. Conclusion Cette cohorte souligne l’importance de considérer l’histoplasmose devant toute présentation dermatologique chez les patients VIH positifs dans les régions d’endémie, spécifiquement lorsque leur taux de CD4 est inférieur à 100/mm3.
Introduction La leishmaniose est une zoonose tropicale négligée causée par des parasites transmis par piqûres de phlébotomes. En zone d’endémie, des lésions typiques de leishmaniose cutanée (LC) (ulcères humides ou croûteux) peuvent faire évoquer le diagnostic, mais le polymorphisme clinique donne lieu à des formes atypiques. L’atteinte articulaire n’est pas classiquement décrite. Nous rapportons trois cas de LC avec présentation articulaire. Observations Cas 1 : un homme de 47 ans, hypertendu, ayant vécu dans le parc naturel du Haut Languedoc, n’ayant pas voyagé, présentait une symptomatologie de canal carpien du poignet droit, avec tuméfaction cutanée. Les prélèvements opératoires trouvaient une ténosynovite du fléchisseur ulnaire du carpe. Une PCR de tissu synovial identifiait L. infantum. Après mauvaise tolérance (insuffisance rénale) d’un traitement par amphotéricine B liposomale, puis échec de miltéfosine, la pentamidine IV permettait une résolution clinique complète.Cas 2 : un homme de 28 ans, habitant en Guyane, se présentait avec deux lésions cutanées croûteuses, à la cheville gauche et au coude droit, associées à une arthrite de la cheville gauche. La PCR cutanée identifiait Leishmania guyanensis. Après échec d’une première ligne par amphotéricine B liposomale, la pentamidine intraveineuse permettait une résolution des symptômes.Cas 3 : un homme de 15 ans, ayant voyagé récemment en Guyane, présentait 14 lésions disséminées ulcérées et nodulaires, accompagnées d’arthralgies diffuses. Un large bilan biologique infectieux et auto-immun était négatif. La PCR cutanée identifiait L. guyanensis. Le traitement par pentamidine IV améliorait les lésions cutanées, mais il présentait par la suite une arthrite spontanément résolutive de la cheville, et des arthralgies migratrices diffuses persistantes trois mois après traitement. Discussion Nous rapportons un cas d’arthrite clinique, de polyarthralgie ainsi qu’une ténosynovite documentée, associés à une LC chez des patients immunocompétents. À ce jour, seuls cinq cas d’atteinte articulaire (mono- ou polyarthrite) documentés ont été décrits, mais ils survenaient tous chez des patients immunodéprimés, leur évolution nécessitant plusieurs lignes de traitement aux résultats variables. Dans notre série, la pentamidine IV était efficace dans deux cas, suggérant une option thérapeutique prometteuse, y compris pour les leishmanioses de l’Ancien Monde. Le premier patient a connu une évolution spontanément favorable et présentait une atteinte articulaire diffuse, suggérant un mécanisme inflammatoire réactionnel. La documentation intra-articulaire, bien que non systématique dans notre série, est cruciale : elle permet de distinguer les infections parasitaires directes des réactions inflammatoires réactionnelles. La diffusion intra-articulaire des médicaments anti-leishmaniens étant très mal connue, cette atteinte rhumatologique pourrait être associée à un échec thérapeutique. Conclusion Ces cas cliniques soulignent l’association possible des arthropathies aux manifestations classiques de leishmaniose.
Objectives Lead poisoning is a major public health problem worldwide. In French Guiana, a French overseas territory in South America, several studies have highlighted the massive lead impregnation of the local population, but the risk factors have not yet been fully elucidated. People working in informal gold mining share part of their lifestyle with French Guianese communities. The aim of this was therefore to estimate the level of lead poisoning in this population and the factors associated with it. Methods This cross-sectional descriptive study was based on data collected by questionnaire and blood sampling. Persons working in informal gold mines were enrolled on the logistic rear bases on the Surinamese and Brazilian sites of the bordering rivers. Blood lead levels were measured on dry blood spots (50 microl). Using a threshold of 100 microg.L-1, single and multiple regressions were used to assess the associated factors. Results Among the 526 persons included, the median age was 38 years and 73.5% were men. The prevalence of lead poisoning was 44.7 % (95%CI=40.4%-49.0%). The factors associated with a BLL over 100 microg.L-1 were: amount of time spent in gold mining (OR=1.31 [1.09-1.58], occupation with mud exposure (OR=1.67 [1.13-2.48]), working in the Southwestern region (OR=2.09 [1.34-3.27]) and consuming game (OR=1.58 [1.06-2.36]). Conclusion The people working on gold mining sites are highly exposed to lead poisoning. The risk factors are suggestive of environmental contamination and differ from those suspected in the population of French Guiana. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement The study was funded by the European Regional Development Fund (FEDER) via the Interregional Amazon Cooperation Program (IACP) 2014-2020 and the Regional Health Agency.

Introduction Overlap autoimmune syndromes (OAS) and mixed connective tissue disease (MCTD) are rare in children. We performed a retrospective, longitudinal and descriptive study of Afro-Caribbean patients from the French West Indies followed for MCTD and OAS to describe their characteristics and outcomes during childhood. Methods Retrospective study from January 2000 to 2023. Listings of patients were obtained from multiple sources: computerized hospital archives and national hospital-based surveillance system, registry of pediatricians and adult specialists in internal medicine and the national registry for rare diseases. MCTD was defined according to Kasukawa’s criteria. OAS was defined as overlapping features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and dermatomyositis/autoimmune myositis (DM/AM). Results Sixteen patients were included over a 23-year period (10 MCTD and 6 OAS). The incidence was 0.23 per 100,000 children-years. The mean age at diagnosis was 11.9 years old (2.4–17) with median follow up of 7.9 years (2.1–19.6). SLE phenotype was present in the highest, followed by SSc and DM/AM. Patients had an average of three flares during childhood (1–7). A quarter (25%) had symptomatic pulmonary arterial hypertension (PAH). Ninety-four percent received steroids during follow-up and 88% required a corticosteroid-sparing therapy. Three patients (19%) developed SLE after more than 10y of follow-up. There were no death and no chronic organ failure. Conclusion This is the largest pediatric cohort of MCTD and OAS in Afro-descendant patients treated in a country with a high standard of care. The clinical evolution did not differ between MCTD and OAS. The main complication was PAH, more frequent in our cohort.
