ABSTRACT

La difilobotriosis es una infección parasitaria causada por cestodos del género Diphyllobothrium, cuyos adultos se desarrollan tanto en mamíferos como en aves. El hombre es también hospedero definitivo y los estadios juveniles se establecen en copépodos y peces teleósteos. En las zonas lacustres del sur argentino existen condiciones ecológicas propicias para la instalación de esta endemia. Durante el período 2002-2006 se atendieron en el Hospital de Enfermedades Infecciosas Francisco J. Muñiz de la Ciudad de Buenos Aires (Argentina) 6 casos con difilobotriosis humana, a los cuales se les realizo el diagnóstico epidemiológico, clínico y de laboratorio. Se efectuó el tratamiento antiparasitario específico y el seguimiento correspondiente postratamiento. Todos los casos evolucionaron favorablemente. La importancia de esta publicación reside en alertar a los agentes que trabajan en salud sobre la presencia de esta patología emergente en zonas patagónicas andinas y en pacientes que consumen pescado crudo o poco cocido, provenientes de esa zona. Se destaca la posibilidad de adquirir esta infección íctica por el consumo de ciertos platos de origen oriental, como el sushi y el sashimi, en otras zonas no endémicas.

ABSTRACT

We have compared the searching of the presence of "honeycomb" structures by direct microscopy on wet mount preparations with the direct immunofluorescence (DIF) for the diagnosis of Pneumocystis carinii pneumonia (PCP) in 115 bronchoalveolar (BAL) fluids. The samples belonged to 115 AIDS patients; 87 with presumptive diagnosis of PCP and 28 with presumptive diagnosis other than PCP. The obtained results were coincident in 114 out of 115 studied samples (27 were positive and 87 negative) with both techniques. A higher percentage of positive results (32.18 percent) among patients with presumptive diagnosis of PCP with respect to those with presumptive diagnosis other than PCP (3.57 percent) was observed. One BAL fluid was positive only with DIF, showed scarce and isolated P. carinii elements and absence of typical "honeycomb" structures. The searching for "honeycomb" structures by direct microscopy on wet mount preparations could be considered as a cheap and rapid alternative for diagnosis of PCP when other techniques are not available or as screening test for DIF. This method showed a sensitivity close to DIF when it was applied to BAL fluids of AIDS patients with poor clinical condition and it was performed by an experienced microscopist

ABSTRACT

The presence of filamentous bacteria morphologically similar to Nocardia in a fresh stool sample from an AIDS patient with pulmonary nocardiosis is here reported. The material was submitted to our laboratory for a parasitologic examination and was stained by the Kinyoun method, revealing numerous delicate, irregularly stained, branching acid-fast filaments. Nocardia asteroides had been isolated from sputum samples of this patient. The patient was a 32 year-old HIV+ female admitted to our center on june 1997 because of productive cough, right-sided thoracic pain and weight loss. Chest X rays showed the presence of right superior lobe excavated pneumonia. This was the first time we had observed filamentous bacteria similar to Nocardia in a stool sample submitted to parasitologic examination. For similar cases, and when its presence was not detected in other specimens collected from the same patient, intestinal endoscopy and biopsy should be performed for eventual lesions and smear examination repeated with Kinyoun stain and cultures for Nocardia.

ABSTRACT

Durante el período comprendido entre enero-diciembre de 1993, en la Sección Parasitología del Hospital de Infecciosas Francisco Javier Muñiz, fueron evaluados con exámenes coproparasitológicos 655 pacientes infectados por el Virus de la Inmunodeficiencia Humana (VIH), hallándose un índice de positividad del 35,4 por ciento. La prevalencia de enteroparasitosis fue la siguiente: Blastocystis hominis 43,5 por ciento - Cryptosporidium spp. 27,5 por ciento - Giardia lamblia 17,2 por ciento - Endolimax nana 10 por ciento -Entamoeba coli 6,5 por ciento - Strongyloides stercoralis 4,3 por ciento - Isospora belli, 3,5 por ciento - Otros 8 por ciento. Algunas enteroparasitosis son una causa frecuente de infecciones oportunistas en pacientes inmunocomprometidos, por lo tanto consideramos importante establecer su prevalencia en la población infectada por el VIH. Esta lista de patógenos se irá incrementando y modificando con la aparición de nuevos agentes etiológicos, la revalorización de la acción patógena de parásitos ya conocidos, y la aplicación de técnicas diagnósticas de mayor sensibilidad, especificidad y confiabilidad

ABSTRACT

It is establish the dissemination enteroparasite by Calliphoridae in a district situated around by Federal Capital of Argentina. The species implicated in this dispersal are: Phaenicia sericata (meigen, 1826); Calliphora vicina Robineau-Desvoidy, 1830; Chrysomya chloropyga (Wiedemann, 1818) and Phaenicia eximia (Wiedemann, 1819). Fifty two flies was studies, thirty four (65%) to belong at the family Calliphoridae. Of this thirteen (38%) have eggs of taeniid and cysts of Entamoeba coli (Grassi, 1879) and Giardia lamblia Styles, 1915.
