Neumonía complicada adquirida en la comunidad: Resolución de los hallazgos clínicos y radiológicos en niños Neumonía complicada adquirida en la comunidad: Resolución de los hallazgos clínicos y radiológicos en niñosIntroducción: las infecciones respiratorias agudas, sobre todo la neumonía, constituyen un grave problema de salud al ser causa frecuente de morbilidad y mortalidad infantil en el mundo. Objetivo: determinar la evolución de los hallazgos clínicos y radiológicos. Material y métodos: se realizó un estudio descriptivo longitudinal;  207 pacientes ingresaron en el Servicio de Neumología del Pediátrico "Juan Manuel Márquez", con diagnóstico de Neumonía Complicada adquirida en la comunidad  del 2008 al 2012. Se estudiaron la edad, el sexo, las características clínicas y radiológicas. Todos los pacientes fueron seguidos a su egreso en una consulta especializada, hasta la desaparición de las lesiones pulmonares. Se utilizó el test Chi cuadrado para conocer la posible homogeneidad de grupo. Resultados: hubo un predominio de pacientes en el grupo de edades de 1-4 años (126 para un 61%). Fueron afectados por igual los varones y las hembras. Los hallazgos clínicos más frecuentes fueron la fiebre, en 207 (100%), el murmullo vesicular disminuido, en 197 (95%) y la polipnea, en 148(71%). Las complicaciones más frecuentes fueron: el derrame pleural y el absceso pulmonar, en 176 pacientes (85%) y 35(16.9%), respectivamente. La resolución de los hallazgos clínicos y radiológicos se produjo en más de la mitad de los pacientes en menos de 2 semanas, seguido de 2-4 semanas, excepto en los pacientes con absceso pulmonar y neumatocele. Conclusiones: la duración de los hallazgos radiológicos fue más prolongada que los clínicos y de estos los que más se prolongaron fueron el murmullo vesicular disminuido, la submatidez y los estertores.Palabras clave: neumonía complicada, neumonía comunitaria, derrame pleural, absceso pulmonar, resolución lenta, características imaginológicas.ABSTRACTIntroduction: acute respiratory diseases overall pneumonia are a critical health problem because are frequent causes of infant morbidities and mortalities around the world. Objective: to determine the evolution of clinical and radiological finding. Material and Methods: a descriptive and longitudinal study was performed it  included 207 patients admitted at the Respiratory Service of the Pediatric University Hospital "Juan Manuel Márquez" with diagnose of Complicated community acquired pneumonia from 2008 up to 2012. The age, sex clinical and radiological characteristics were studied. The entire patient enrolled was following up from the hospital discharged up to lung lesions disappear in the respiratory outpatient consult. Chi-square test was used to know the possible homogeneity’s group. Results: there was a preponderance of patient aged from 1 to 4 years old and were affected male and female equally. The clinical findings most frequent were fiber in 207(100%) vesicular breath sound diminished in 197(95%) and polypnea in 148(71%). The most frequent complications were pleura effusion and lung abscess in 176 (85%) patients and 35(16.9%) respectively. The solution of clinical and radiological findings appeared in the half of patients in less than 2 weeks, followed of 2-4 weeks excepting in patients with lung abscess and pneumatocele. Conclusions:  length of radiological findings was more extended than clinical and from these the most extended were vesicular breath sound diminished, sub dullness and the rattles.Key words: complicated pneumonia, community pneumonia, pleura effusion, slow solution, images characteristics.

In this paper, we propose a novel home area networks (HAN) architecture using MMW radio-over-plastic optical fiber (MMW/RoPOF) to provide high-speed wireless connections to end users. The proposed HAN can support bidirectional half-duplex communication be... see more

Future communication needs to be ubiquitous, broadband, convergent, and seamless. Radio over fiber (RoF) technology is one of the most important enabler in access network for the technologies. Adoption of RoF faces bottleneck in optoelectronics, that they... see more

A periodic leaky-wave antenna (LWA) design based on low loss substrate-integrated waveguide (SIW) technology with inset half-wave microstrip antennas is presented. The developed LWA operates in the V-band between 50 and 70 GHz and has been fabricated usin... see more

Risk of DM increased along with increased of age. Compared to those in the 15-39 years age group, those in the =56 years age group had a 4.9-fold risk for DM (ORa=4.88; 95% CI=3.18-7.49), whereas the 40-55 age group had a 2.4-fold risk for DM (ORa=2.42, 9... see more

Background; The incidence of overnutrition for elementary school children continues to increase rapidly throughout the world and has reached an alarming stage due to excessive energy intake. Students who are overweight are caused by the school environment... see more

Due to an increase in the number of radio devices with different types of signals and to increase the speed of information transmission, it is necessary to take into account the increase in the probability of erroneous reception of signals as a result of ... see more
