We report the case of a 72-years-old woman who complains fever, headache, malaise and weakness, with a history of tooth extraction five days before the onset of this symptoms. On laboratory samples, Actinomyces israelii was isolated from her blood culture. We suggest that, although bacteremia caused by this organism is uncommon, it should be take in account, specially in febrile patients who were underwent an odontologic procedure.

Consumption of transgenic foods constitutes a potential health risk. However, in Peru there is a lack of updated and reliable information on the presence of transgenics in food and on the relevant data on their labeling; in the same way about the food consumed by animals for supply, whose products are going to be ingested by humans. Objetive. To determine the transgenicity, through the detection of the 35S promoter, in industrialized corn food products for human and animal consumption, which are marketed in Lima and to verify if the labeling mentions whether or not it contains transgenic sequences. Methods. 30 food samples for human consumption and 10 for consumption by animals for production were analyzed; and the labeling was revised. The Dneasy Mericon Food kit was used for DNA extraction, the Real Time-PCR method for P35S detection using the Mericon Screen 35S kit, and the Mericon Qu...

Introducción. El consumo de alimentos industrializados que contienen organismos genéticamente modificados (OGM) se ha incrementado notablemente. Desde su inicio ha generado crecientes controversias debido a que se considera de riesgo para la salud. En Perú se carece de información científica sobre los OGM en alimentos industrializados. Objetivo. Detectar y cuantificar molecularmente los indicadores de transgenicidad P35S y TNOS, y la soya transgénica Roundup Ready en alimentos industrializados de soya; y verificar su mención en la etiqueta. Métodos. Analizamos 30 muestras, para extraer el ADN utilizamos los kits Dneasy Mericon Food y Dneasy Power Soil. Para la detección y cuantificación de las secuencias transgénicas usamos la técnica PCR en tiempo real con los kits Mericon. Resultados. Detectamos transgenicidad en el 100% de las muestras y soya Roundup Ready en el 66,7%. El ...

Objectives: To determine dermatomycoses epidemiological evolution in outpatients during the period 1976-2005. Design: Descriptive, retrospective, and analytical study. Setting: Daniel Alcides Carrion Institute of Tropical Medicine, Universidad Nacional Mayor de San Marcos, Lima, Peru. Participants: Patients positive to dermatomycoses. Interventions: Medical records of 7 185 (55.3%) dermatomycoses-positive patients were reviewed. Main outcome measures: Etiologic agent, season, gender, age, and clinical forms. Results: Females (52.1%) and the 16 to 30 year-old group (42.7%) were the most affected. Most frequent dermatomycoses was onychomycosis (43.6%). Most prevalent pathogens were Trichophyton rubrum (33.2%), Candida albicans (15.3%), Candida non albicans (11.8%), Trichophyton mentagrophytes (9.4%), Malassezia spp. (9.1%), and mixed infections (7.2%). The fungal scalp infection showed ste...
