Summary Introduction:?The literature reports that when it comes of instrumental assessment of swallowing in children, undoubtedly, video fluoroscopy of swallow offers great advantages over the endoscopic study. Objective:?Check the risk of aspiration pneumonia after the study of swallowing by video fluoroscopy, in children with dysphagia. Method:?In a study of prospective cutting, participated 16 children aged between 6 months and 10 years, with an average of 5,2 years, referred for study of swallowing by video fluoroscopy. Were tested 4 consistencies, pudding, nectar, honey and liquid. The presences of signs and/or respiratory symptoms were evaluated pre and post study of deglutition by video fluoroscopy, through history and clinical exam. When necessary was asked chest x-ray. Results:?Of 16 children, 5 didn't presented dysphagia. In 11 children the exam showed 4 with mild dysphagia, 2 moderate and 5 severe, as classification of OTT (1996) - Classification of severity of dysphagia to the video fluoroscopy. Of the 7 children who aspirated during the exam, only 1 presented respiratory symptoms after the deglutition study, but without signal of pneumonia to the physical examination. Conclusion:?In the studied population there were no occurrences of aspiration pneumonia after the study of deglutition was performed by video fluoroscopy, despite the occurrence of aspiration during the exam in about 50% of cases.
Introduction Technological advances have provided a large variety of instruments to view the swallowing event, aiding in the evaluation, diagnosis, and monitoring of disturbances. These advances include electromyography of the surface, dynamic video fluoroscopy, and most recently sonar Doppler. Objective To characterize swallowing sounds in typical children through the use of sonar Doppler. Method Thirty newborns participated in this prospective study. All newborns received breast milk through either their mother's breasts or bottles during data collection. The newborns were placed in either right lateral or left lateral positions when given breast milk through their mother's breasts and in a sitting position when given a bottle. There were five variables measured: initial frequency of sound wave (FoI), frequency of the first peak of the sound wave (FoP1), frequency of the second peak of the sound wave (FoP2), initial intensity and final sound wave (II and IF), and swallowing length (T), the time elapsed from the beginning until the end of the analyzed acoustic signal measured by the audio signal, in seconds. Results The values obtained in the initial frequency of the babies had a mean of 850 Hz. In terms of frequency of first peak, only three presented with a subtle peak, which was due to the elevated larynx position. Conclusion The use of sonar Doppler as a complementary exam for clinical evaluations is of upmost importance because it is nonintrusive and painless, and it is not necessary to place patients in a special room or expose them to radiation.
Antecedentes: La tuberculosis multirresistente (MDR-TB) y extremadamente resistente a los medicamentos (XDR-TB) es un grave problema de salud pública en todo el mundo, con una alta tasa de mortalidad. Por ello, se ha propuesto reducir la mortalidad y la incidencia para el año 2030. El objetivo de este estudio es realizar un análisis bibliométrico de la producción científica de TB-MDR y TB-XDR entre 1990 y 2019. Métodos: Estudio bibliométrico utilizando la base de datos Scopus. Extraemos la investigación anual, revistas, autores, instituciones, idioma y países. Los datos fueron analizados en Microsoft Excel. Además, los gráficos de clúster y las redes colaborativas se realizaron en VosViewer. Resultados: Obtuvimos 6171 documentos, de los cuales 4256 (68,97%) fueron artículos, 630 (10,21%) reseñas, 524 (8,49%) cartas, 224 (3,63%) notas y 537 (8,70%) otros tipos. La mayoría se publicaron en inglés con 5474 (88,71%) documentos. Las revistas con más publicaciones fueron International Journal of Tuberculosis and Lung Disease, seguida de Plos One y European Respiratory Journal. Los países con mayor producción fueron Estados Unidos, Reino Unido, Sudáfrica e India. Conclusiones: La mayor producción científica se concentra en los países de habla inglesa y se trata principalmente de artículos originales. Es necesario incentivar la investigación en países de bajos ingresos con mayor prevalencia de tuberculosis.
