During 2010–2013, we recruited 16 persons with confirmed Mayaro virus infection in the Peruvian Amazon to prospectively follow clinical symptoms and serologic response over a 12-month period. Mayaro virus infection caused long-term arthralgia in more than half, similar to reports of other arthritogenic alphaviruses.
Abstract.In the Americas, 8 million people are infected with Chagas disease, and an additional 90 million people are at risk for infection. Little is known about the role bats play in the sylvatic transmission cycle of Trypanosoma cruzi, the parasite causing Chagas disease. Here, we captured bats in the villages of Palmiche, Pachacutec, Nuevo San Martin, and Mayuriaga located in the Datem del Marañon Province in Loreto, Peru. Venous blood samples were collected by cardiac puncture or from the upper extremities, and trypanosomatids were identified by microscopy and molecularly. We collected blood samples from 121 bats on filter paper for molecular studies and 111 slides for microscopic examination of thin and thick blood smears from 16 different bat species. The prevalence of trypanosomatids in all bats species was 34.7% (42/121) and the prevalence of T. cruzi was 4.1% (5/121). In hematophagous bat species, the prevalence of trypanosomatids and T. cruzi was 36.9% (27/73) and 2.7% (2/73), respectively. In non-hematophagous bats, the prevalences of trypanosomatids and T. cruzi were 31.2% (15/48) and 6.2% (3/48), respectively. Also, we confirm the presence of T. cruzi in salivary glands of hematophagous bats Diaemus youngi. These results suggest a sylvatic cycle of trypanosomatid transmission in which bats may harbor infectious T. cruzi parasites that could be transmitted to humans via hematophagous bat bites or salivary contamination by non-hematophagous bats of vegetables consumed by humans.
Posterior reversible encephalopathy syndrome is a clinicoradiologic entity associated with diverse medical conditions. It is very important to properly recognize this condition because early diagnosis and treatment usually result in its complete resolution, whereas a delay in giving an adequate therapy may lead to permanent neurologic sequelae. A case of posterior reversible encephalopathy syndrome in a female patient with an overlap syndrome of systemic lupus erythematosus and systemic sclerosis is presented here.
Objetivos: Describir las enfermedades registradas por contingencia laboral en los descansos médicos emitidos por el Seguro Social de Salud (EsSalud) a nivel nacional, 2015-2016. Materiales y métodos: Se realizó un estudio descriptivo transversal de la base total existente en EsSalud. El estudio abarcó todos los certificados de incapacidad temporal para el trabajo (CITT) reportados como enfermedades por contingencia laboral en el sistema de gestión hospitalario de EsSalud a nivel nacional. Resultados: De 256 CITT reportados, ingresaron al análisis 188 CITT que cumplieron el criterio de inclusión (encontrarse en lista peruana de enfermedades profesionales). Los trastornos músculo esqueléticos representaron la patología más frecuente, presentando mayor cantidad de días por incapacidad. En 39 CITT no se logró identificar a que actividad productiva se encontraban registradas. Conclusiones: En las enfermedades registradas por contingencia laboral que requirieron descanso médico, la gran mayoría corresponde a trastornos musculo esqueléticos, dentro de las cuales el lumbago tuvo mayor frecuencia. Existe la necesidad de realizar mayor investigación para definir mediante los criterios de causalidad si las enfermedades mencionadas corresponden a la definición de enfermedades profesionales.
Sr. Editor. Luego de los informes preliminares de los primeros casos por Hantavirus en la ciudad de Iquitos (1,2) , la infección por este género ha cobrado importancia en la Salud Pública por la alta letalidad (40-60%) (3). Asimismo, es necesario describir algunos aspectos para establecer las medidas apropiadas de control. Estos pueden resumirse en cuatro preguntas:
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
