ResumenLa cistitis enfisematosa hace referencia a una entidad infrecuente, generalmente secundaria a infecciones de vías urinarias bajas, que por diferentes mecanismos producen gas alrededor de la vejiga. Esta patología se asocia a gérmenes (E. Coli, Enterobacter Arogenes, y Klebsiella, entre otros), y factores de riesgo como género femenino, edad avanzada y diabetes. Este diagnóstico requiere un manejo oportuno, con antibioticoterapia dirigida y control de comorbilidades asociadas; a continuación, se reporta el caso de un paciente masculino de 81 años, en el hospital de San José de Bogotá, a quien se le diagnostica esta patología, con el respectivo aislamiento microbiológico, factores de riesgo, diagnóstico y manejo instaurado. Palabras clave: cistitis, diabetes mellitus tipo 2, infecciones urinarias, antibacterianos.

Background: Neisseria meningitidis is the most frequent etiologic agent of meningococcemia and meningitis. In both scenarios it is capable to produce clinical manifestations of great importance. The purpura fulminans is part of the cutaneous signs caused by this bacterial agent. It begins as a cutaneous hemorrhage and necrosis due to vascular thrombosis and disseminated intravascular coagulation secondary to immunological, genetic, and vascular events. Being in this infectious disease a factor of poor prognosis. Case presentation: We present a case of purpura fulminans where the etiological agent isolated by blood culture was Neisseria meningitidis in a Patient at the Hospital de San José in the city of Bogotá. The patient shows on physical examination erythematous macula type lesions with irregular edges like purpuric lesions. The isolated bacteria was Neisseria meningitidis and the diagnosis of meningococcemia was did. Conclusion: Meningococcemia it is considered that the most frequent etiologic agent of this entity is Neisseria meningitidis. Typically, it can start as a cutaneous hemorrhage and necrosis due to vascular thrombosis and disseminated intravascular coagulation, being a presentation a factor of poor prognosis.

The pursuit of low losses and low distortion are necessary conditions to improve the signal integrity. As mentioned in [1], it is sometimes said that thereare two types of engineers—those who have signal integrityproblems and those who will.As clock frequencies increase,magnifying signal integrityproblems, this saying willbecome even more accurate.On the other hand, the usage of the technology is now a day unavoidable. Thus, to avoid the electromagnetic radiationdirectly on the brain, should be recomendablethe useof the hand off device since the integrated inalambric amplifiers of new generation genertea lot of energy (power). Besides, it is convenient that the user of that technology be aware to the activities he is doing to avoid accidents mainly when he is manipulating some kind of equipment or driving a vehicle.As mentioned in[2], the power amplifier (PA) is a critical component whitin a WLAN transmitter because PA performance affects wireless coverage area, data rate capacity, and battery life.Â
