The first successful case of surgical treatment of a superior mesenteric artery aneurysm is described at the Honorio Delgado Regional Hospital III in Arequipa. The case report involved a patient who had experienced 18 months of epigastric pain and was diagnosed with computed tomography and computed tomography. The patient underwent laparotomy for aneurysm resection and a bypass of the superior mesenteric artery was performed using a polytetrafluoroethylene graft. The patient had a rapid and uncomplicated recovery and has since progressed well. This type of aneurysm is rare, with no epidemiological data in Peru. Surgical treatment requires careful planning due to the high risk of rupture and mortality. Technological support is essential in the surgical approach of these patients, which is often a challenge in non-specialized public hospitals.

Introducción: La infección del tracto urinario (ITU) es muy frecuente tanto en la comunidad como en el entorno hospitalario. Obtener un diagnóstico y antibiograma rápido del agente etiológico permite un tratamiento específico oportuno llevando a una menor morbilidad y mortalidad y disminuyendo el riesgo de resistencia a los antibióticos. La identificación directa de patógenos del tracto urinario por la técnica MALDI-TOF MS (Matrix Assisted Laser Desorption/Ionization Time-of-Flight Mass-Spectrometry) no ha sido usada ampliamente para procesar muestras de orina directamente de los pacientes sin obtener un cultivo previo. Objetivo: Evaluar la concordancia entre los resultados de la identificación directa por análisis MALDI-TOF y urocultivo de patógenos del tracto urinario de muestras de orina de pacientes del Hospital Nacional Carlos Alberto Seguín Escobedo (HNCASE) en el per...
