ABSTRACT
RESUMEN Se presentó un caso clínico de un paciente de seis años de edad, con toxocariasis ocular. La manifestación clínica fue disminución de la agudeza visual monocular. El fondo de ojo izquierdo mostró un granuloma retiniano periférico, asociado a un desgarro retiniano perilesional. El examen oftalmológico confirmó el diagnóstico de Toxocara ocular. El paciente fue tratado posteriormente mediante corticoides sistémicos y fotocoagulación láser focal en el desgarro retiniano (AU).
ABSTRACT We present the clinical case of a male patient, aged 6 years, with ocular toxocariasis. The clinical manifestation was monocular visual acuity decrease. The left ocular fundus showed a peripheral retina granuloma, associated to a perilesional retinal tear. The ophthalmological examination confirmed the diagnosis of ocular Toxocara. After that the patient was treated using systemic corticoids and focal laser coagulation in the retinal tear (AU).

A 24-year -old woman 2-3 months after a normal parturation presented geophagy. Due to hypermenorrhea she consulted a gynecologist and in a hemogram a 57 percent (6, 893 x mm3) hypereosinophilia was detected. A chest TAC showed bilateral pulmonary nodules. The following tests resulted positive: ELISA IgG for toxocariasis 1: 1000, isohemagglutinins anti A 1:2048 and anti B 1:512. The patient was treated with albendazole and prednisone during 10 days. One month after treatment eosinophilia decreased to 2.590 x mm3 and ELISA IgG for toxocariasis descended to 1:128. Different aspect of human toxocariasis are commented. When hypereosinophia is observed in adult patients, toxocariasis must be checked

Toxocariosis is a zoonosis which has beem widely studied in dogs. However, not much is known about this parasitosis in cats. The aim of the present work was to determine the frequency of Toxocara cati in domestic cats in Mexico City and the State of Mexico. Feces of 660 domestic cats were studied by the Faust concentration-floating test; 401 samples were from cats living in Mexico City of which 308 lived in houses and 93 in apartments; 231 were from urban areas of the State of Mexico an 28 from a rural area of the same state. The total frequency of T. cati eggs obtained from domestic cats in Mexico City was 42.9 percent; in cats living in apartments it was 18.3 percent and in cats living in houses it was 50.3 percent. In domestic cats from the State of Mexico, T. cati frequency was 36.4 percent in the urban and 21.4 percent in the rural areas. We consider that toxocariosis frequency observed at the two studied sites is high and that the need to prevent dissemination of the infectious forms of T. cati is urgent,as it the necessity of informing the population of the risk of living with T. cati parasited animals and of the anatomopathological alterations caused by T. cati in man

La toxocariasis es una infección por un nematodo que tiene dos formas clínicas de manifestarse: larva migrans visceral y toxocariasis ocular. estas últimas es casi exclusivamente unilateral y típica de la edad infantil; sin embargo, se ha descrito en individuos desde los 2 a los 40 años de edad. Puede presentarse con disminución de la visión, estrabismo, leucocoria o uveítis. Más frecuente es la presencia de un granuloma subrretiano en el polo posterior, o bien un granuloma coriorretiniano periférico. Menos frecuente es la existencia de una endoftalmitis con desprendimiento de retina. Las tres formas de afección ocular presentan las mismas patogenia. Presentamos dos casos clínicos correspondientes a un granuloma coriorretiniano periférico en un varón de 42 años de edad, y a un granuloma de polo posterior en un varón de 29 años. En ambos pacientes el diagnóstico se realizó fundamentalmente por los signos y síntomas, el aspecto clínico típico del fondo de ojo y los antecedentes personales

One hundred and twenty-six patients with recurrent abdominal pain and other associated symptoms and signs were classified into two groups. The first comprised thirty-eight patients who were subjected to emergency surgery for exploration and/or appendicectomy and contributed to liver biopsy specimen examination for Toxocara eosinophilic granuloma [twenty-two were proved positive]. The second group comprised ninety-eight patients without available biopsy specimens. Toxocara IgG antibodies were sought in sera of both groups by Enzyme-linked immunosorbent assay [ELISA] using excretory - secretory larval Toxocara antigen [ES antigen]. Similar frequencies of age and symptoms and signs [cough, wheeze, hepatomegaly and eosinophilia] among Toxocara seropositive patients, both in histopathologically proved group [22] and biopsy lacking group [98] led us to consider anti-Toxocara IgG ELISA-ES a useful tool in elucidating toxocariasis as a causative agent of significant proportion of children complaining of recurrent abdominal pain with obscure aetiology

Se presenta un caso de toxocariasis diagnosticado en una paciente de 18 años hospitalizada por un cuadro clínico de comienzo brusco caracterizado por disnea, dolor torácico, pérdida del conocimiento con relajación de esfínteres y hepatomegalia dolorosa. El estudio realizado demostró una moderada leucocitosis con eosinofilia de 24 a 55% y reacción de toxocariasis positiva 1/64. La enferma fue tratada con tiobendazol observando una rápida mejoría subjetiva con desaparición de la sintomatología respiratoria, digestiva y neurológica y con gradual reducción de la eosinofilia y del título de la reacción de toxocariasis

En esta comunicacion se pretende condensar los datos mas importantes del protocolo de trabajo sobre el tema de la toxocariasis ocular en Bogota, asi como dar a conocer los resultados de esta investigacion, cuyos propositos han sido contribuir al desarrollo del laboratorio diagnostico de parasitosis a traves de la estandarizacion de la tecnica ELISA para Toxocara canis, y alertar acerca de la presencia de la parasitosis canina en humanos, con el impacto de esta sobre la morbilidad ocular y la incapacidad permanente por ceguera, teniendo en cuenta la intratabilidad de la lesion una vez declarada
