RESUMO
El síndrome de Evans es la coexistencia de trombocitopenia autoinmune con anemia hemolítica autoinmune. Raramente se presenta durante el curso de un embarazo. Esto dificulta las opciones terapéuticas, dado que algunos de los agentes utilizados para el tratamiento son teratogénicos. Los efectos del síndrome de Evans en el feto y recién nacido se desconocen dado el escaso número de casos publicados. Presentamos el caso de una paciente con diagnóstico preconcepcional de síndrome de Evans, que presenta una crisis hemolítica en el curso de una gestación, y diagnóstico de restricción del crecimiento intrauterino (RCIU), en tratamiento en la Clínica Ginecotocológica "A" del Centro Hospitalario Pereira Rossell (CHPR), de Montevideo, Uruguay. Se analizan opciones terapéuticas y evolución, así como publicaciones previas...
Evans' syndrome is the coexistence of autoimmune thrombocytopenia with autoimmune hemolytic anemia. It is rarely found during the course of a pregnancy. This makes treatment options more difficult, since some therapeutic drugs are teratogenic. The effects of Evans' syndrome in the fetus and newborn are unknown given the low number of reported cases. We report the case of a patient with preconceptional diagnosis of Evans' syndrome, who develops a hemolytic crisis during the course of a pregnancy, and diagnosis of intrauterine growth restriction (IUGR), treated at Clinica Ginecotocologica "A" at the Pereira Rossell Hospital Center, in Montevideo, Uruguay. Treatment options and evolution are analyzed, as well as previous reports...

The presence of Aeromonas ssp. in food has been demonstrated. They are often introduced from water, which is the natural habitat of many species and is thought to be the main source of contamination. The occurrence of Aeromonas ssp. was investigated in 70 water samples of a bovine abattoir. Aeromonas ssp. were present in 21.4(per cent) of water samples. A.hydrophila was isolated from 11.4(per cent) of supplying water samples and from 25.7(per cent) of the water drained from carcasses, whereas A. sobria was sole isolated from 5.7(per cent) of supplying water samples. Although greater number of positive samples were from water drained from carcasses, only A.hydrophila isolates were present. This suggests that the supplying water is the source of contamination. The antibiotic susceptibility testing revealed all strains were resistant to ß-lactam antibiotics. However, the susceptibility to other antimicrobials was variable, being A.hydrophila more resistant than A. sobria strains. The investigation for virulence factors revealed positive reactions of hemolysis and hemagglutination. The results indicate that Aeromonas ssp. are present in the supplying water system. These microorganisms may be a potential contaminant of carcasses and widespread in derived food.

Neste estudo foram avaliadas a estabalidade da atividade hemolítica, a resistência a antibióticos e a detecção de plasmídios em cepas orais de A. actinomycetemcomitans. As características foram estßveis durante os diferentes repiques sucessivos realizados nas condições de nosso experimento. Todos os isolados de A. actinomycetemcomitans testados, perderam ou mudaram algums características fenotípicas tal como morfologia colonial e o crescimento em meio líquido.
