Abordaje terapéutico de los aneurismas aórticos asociados a neoplasia / Association between aortic aneurysm and malignant neoplasia therapeutic accesible

La asociación entre un aneurisma aórtico y neoplasia maligna es poco frecuente. Cuando se encuentra, es necesario tomar una decisión en cuanto a cuál deberá ser resecado primero. En el presente artículo, se muestra una serie de nueve pacientes con aneurisma de la aorta y carcinoma en localizaciones intra o extraabdominales, su tratamiento y su evolución postoperatoria. Finalmente, se hace una serie de comentarios en cuanto a las pautas de tratamiento cuando se encuentra esta asociación

Comparative analisis plasmids from nosocomial Klebsiella pneumoniae strains isolated from two hospitals

A total of 46 clinical isolates of Klebsiella pneumoniae were studied. Of these, 33 were from "Hospital Infantil de Mexico" (HIM) and 13 from "Hospital General de Mexico" (HGM). The susceptibility of these strains to five antibiotics, as well as the plasmid DNA profiles, were determined for each group. Antibiotic susceptibility profiles were very similar in strains from both hospitals; however, most of the strains analyzed exhibited heterogeneous plasmid DNA profiles. Results showed that strains isolated in the two hospitals did not differ regarding morphology, biochemical profiles, antibiotic susceptibility or plasmid populations, and these characteristics may not be used as markers to differentiate Klebsiella pneumoniae strains from different hospitals
