Toxocariasis is an infection caused by nematode larvae from Toxocara genus, and the most important infective agents for humans are Toxocara canis and Toxocara cati, parasites from dogs and cats, respectively. Toxocara species belong to Ascaridida order, Ascaridodea super-family, Toxocaridae family. The disease in humans is mainly caused by T. canis. Human toxocariasis was described for the .rst time by Wilder in 1950, who identi.ed a then-unknown nematode in a child presenting with a granulomatous lesion in one of his eyes. In 1952, Beaver reported cases of a multi-systemic, chronic, and sever disease, associated to hypereosinophilia. In Peru, in 1991, Maguiña et al. reported the very.rst cases of visceral larva migrans, and in 1999, Miranda et al. reported the very .rst cases of ocular larva migrans.

Objetivos: Determinar las características epidemiológicas, clínicas, datos de laboratorio y tratamiento de la Bartonelosis aguda en niños. Materiales y métodos: Se revisaron las historias clínicas de 32 niños con Bartonelosis aguda, internados en el Hospital Nacional Cayetano Heredia y en el Instituto Especializado de Salud del Niño entre 1993 y 2003. Resultados: La edad promedio fue 9,8 años, 72% fueron varones, los lugares de exposición probable fueron principalmente las zonas endémicas de los valles interandinos de Perú, pero hubieron pacientes procedentes de zonas no endémicas de la selva alta; fueron nativos de éstas zonas el 72%. Los síntomas principales fueron fiebre (97%), hiporexia (91%), síntomas gastrointestinales (66%) y malestar general (53%); los signos principales fueron palidez (97%), hepatomegalia (78%), taquicardia (75%) y linfadenomegalia (72%). ...

Introduction: the zoonotic ascarid Toxocara canis has been suggested as a possible etiologic agent of asthma. Objective: explore the association between T. canis infection and asthma in children seen at the Hospital Nacional Cayetano Heredia (HNCH), Lima, Perú, and evaluate other factors associated with T. canis infection in the population studied. Materials and methods: this is a case-control study involving 75 asthmatic and 75 nonasthmatic children, from 2 to 13 years who were evaluated at the HNCH in 2002. A questionnaire was applied referring to the interest variables. Seroprevalence of T. canis was determined through a T. canis ELISA IgG test for. Results: the seroprevalence of toxocariosis was 16 %. No significant association was found between the seropositivity for T. canis and asthma. A significant association between a higher frequency of nocturnal sibilance crises an...

Objective: To describe clinical, image, and laboratory findings in patients with eye toxocariasis seen in three of the main ophthalmology services in three national hospitals in Lima, Peru.   Material and method: records of patients with a presumptive diagnosis of ocular toxocariosis between January 1997 and January 2010 in Cayetano Heredia National Hospital, Arzobispo Loayza National Hospital and the Instituto Nacional de Salud del Niño (national reference center for sick children).   Results: Forty-one cases were found. Their ages were between 5 moths and 62 years (11.6 ± 8). The most frequent symptom was reduced visual acuity. Most frequent findings in eye funduscopy and image studies were peripheral granulomata and posterior uveitis.Most patients had positive serology tests for Toxocara canis.   Conclusions: Most patients in this review ere childr...
