ABSTRACT
La enfermedad de Graves Basedow es una enfermedad autoinmune organoespecìfica ocasionalmente asociada a LES. Como dicha coincidencia mòrbida la conocìamos a travès de publicaciones aisladas, quisimos comunicar el caso de una niña de 12 años con enfermedad de Graves Basedow tratada quirùrgicamente, que desarrollò a los pocos meses de la tiroidectomìa una nefropatìa lùpica.

Se considera que la enfermedad de Chagas es el resultado de la interacciòn entre el paràsito (T.cruzi), los vectores triatominos y los huèspedes que viven en condiciones socioeconòmicas de pobreza. La interrupciòn del la transmisiòn vectorial se basa en el rociamiento con insecticidas, el mejoramiento de las viviendas, los programas de educaciòn sanitaria y la participaciòn comunitaria. Sin embargo, la evaluaciòn de la efectividad de tales medidas ha sido realizada aisladamente, lo que les resta valor conclusivo. En el presente estudio se evaluò la capacidad de los niños, que concurren a la escuela de una comunidad donde se desarrollò un proyecto de control de la enfermedad de Chagas, para comprender aspectos bàsicos de la enfermedad asì como para reconocer rastros de triatominos. El èxito de los niños en ambas evaluaciones justifica la incorporaciòn de informaciòn sobre la enfermedad y su control en los programas educativos regulares de zonas endèmicas a fin de preparar a los niños para un eficaz monitoreo de intervenciones de control

Insecticidal residual effect and triatomine infestation rates in houses of a community fumigated with lambdcyhalothrin (Icon) are reported. No mortality was observed in 5th-instar Triatoma infestans nymphs in 72-hr exposure test on three different surfaces, one month after fumigation for a dose of 31.5 mg am/m2. However, during post-exposure observation a mortality of 60 was recorded for those insect exposed on sprayed woodboard. The results observed with mud-containing treated walls, were markedly poorer (0 of mortality). Twelve month after spraying 40 of mortality was observed on first-instar T. infestans nymphs in 72-hr exposure test on woodboard, but lower mortality rates were observed in mud-containing materials. When the effect of deltamethrin (109 mg ai/m2) and lambdcyhalothrin (94 mg ai/m2) was compared, the former did not appear to be superior at similar loads. Both have showed a mortality rate of 30 on 5th-instar T. infestans nymphs three months post-fumigation. The dose utilized in the field fumigation was enough to get a significant (p < 0.0001) control of triatomine domestic infestation, since it was sufficient to keep 95 of the houses uninfested throughout 21 months following treatment, when compared with baseline situation. A remarkable knock-down effect on adult and nymphs forms of the insect and a high in situ mortality were observed as a result of its application, even at very low doses.

One-hundred fish samples of different species, capture between October and Novenber 1989 from Paraguay and Paraná rivers, were evaluated in terms of total mercury content in fresh meat. Specimens were captured at Bahía Negra, Valle-mí, Concepción, Asunción and Pilar on Paraguay river, and at Ayolas an Paraná river. The samples captured at different locations on Paraguay river showed a mercury content of 250.3mg/kg. Consindering the meam values for mercury content in the fishes from Paraguay river from north to south, the lowest value was recoded in Bahía Negra. The mean values of the samples from the other locations on Paraguay river ranged from 209.5 mg/kg on Asunción, to 307.2 mg/kg on Pilar. The mean mercury concentration for the samples from each location are below the safety limit (500 mg/kg), but some specimens showed higher values. It is very interesting to note that the specimens procured from Paraná river (Ayolas) showed the higher mean value for the mecury content. There is certain pattern in the species showing both the lowest and the highest mercury concentration vary in each location. This fact cuold be related more with the food intake charasteristcs of each species more than with the location of the capture. We found that specimens of Piaractus mesopotamicus (pacú) and Doradidae sp. (armado) from different places showed the lowest mercury contents, and specimens of Pseudoplatystoma coruscans (surubí) and Salminus brasiliensis (dorado) showed the highest levels
