RESUMO
Introduction: the recent mpox outbreak was considered an international public health emergency. Objective: describe the epidemiological and clinical characteristics of mpox in a hospital in the province of Buenos Aires. Methods: case series study in patients ≥15 years of age in the Dermatology service of the Hospital Interzonal General de Agudos "San Martín" in La Plata between August and November 2022. Results: 10 patients were included. The mean age of presentation was 35 years. Seven of the patients were men and the remaining three were women. Most of them presented risky sexual intercourse as an epidemiological history. Pseudopustules were observed in 70% of the patients and all had genital, gluteal or perianal lesions. The complications observed were: local edema, proctitis, conjunctivitis and pharyngitis. Conclusion: we present 3 female patients out of a total of 24 women reported in the country, which represent only 2% of mpox infections in Argentina. In most cases we observe pseudopustules, an elementary lesion recently described for this entity. One patient presented ocular involvement, a complication reported in 1% of cases in the current outbreak.
Introducción: el brote reciente de mpox fue considerado una emergencia de salud pública internacional. Objetivo: describir las características epidemiológicas y clínicas de mpox en un hospital de la provincia de Buenos Aires. Métodos: estudio de serie de casos en pacientes ≥ 15 años en el servicio de Dermatología del Hospital Interzonal General de Agudos "San Martín" de La Plata entre agosto y noviembre del año 2022. Resultados: se incluyeron 10 pacientes. La edad media de presentación fue 35 años. Siete de los pacientes eran hombres y las tres restantes fueron mujeres. La mayoría de ellos presentó relación sexual de riesgo como antecedente epidemiológico. En el 70% de los pacientes se observaron pseudopústulas y todos tuvieron lesiones a nivel genital, glútea o perianal. Las complicaciones observadas fueron: edema local, proctitis, conjuntivis y faringitis. Conclusión: presentamos 3 pacientes de sexo femenino del total de 24 mujeres reportadas en el país, que representan sólo el 2% de las infecciones por mpox en Argentina. En la mayoría de los casos observamos pseudopústulas, lesión elemental descripta recientemente para esta entidad. Un paciente presentó compromiso ocular, complicación informada en un 1% de los casos en el brote actual.

To date, more than 2400 valid fish species have been recorded in the Amazon basin. However, some regions remain poorly documented. This is the case in the Beni basin and in particular in one of its main sub-basins, the Tuichi, an Andean foothills rivers flowing through the Madidi National Park in the Bolivian Amazonia. The knowledge of its ichthyological diversity is, however, essential for the management and protection of aquatic ecosystems, which are threatened by the development of infrastructures (dams, factories and cities), mining and deforestation. Environmental DNA (eDNA) has been relatively little used so far in the Amazon basin. We sampled eDNA from water in 34 sites in lakes and rivers in the Beni basin including 22 sites in the Tuichi sub-basin, during the dry season. To assess the biogeographical patterns of the amazonian ichthyofauna, we implemented a metabarcoding approach using two pairs of specific primers designed and developed in our laboratory to amplify two partially overlapping CO1 fragments, one of 185bp and another of 285bp. We detected 252 fish taxa (207 at species level) among which 57 are newly identified for the Beni watershed. Species compositions are significantly different between lakes and rivers but also between rivers according to their hydrographic rank and altitude. Furthermore, the diversity patterns are related to the different hydro-ecoregions through which the Tuichi flows. The eDNA approach makes it possible to identify and complete the inventory of the ichthyofauna in this still poorly documented Amazon basin. However, taxonomic identification remains constrained by the lack of reference barcodes in public databases and does not allow the assignment of all OTUs. Our results can be taken into account in conservation and management strategies and could serve as a baseline for future studies, including on other Andean tributaries.
