Respiratory syncytial virus (RSV) has a major role in respiratory infections in young infants around the world. However, substantial progress has been made in recent years in the field of RSV. A wide variety of observational studies and clinical trials published in the past decade provide a thorough idea of the health and economic burden of RSV disease in the developing world. In this review, we discuss the impact of RSV burden of disease, major gaps in disease estimations, and challenges in generating new therapeutic options and an immune response against the virus, and briefly describe next generation technologies that are being evaluated.
Presentación de casos clínicos RESUMENLa pericarditis constrictiva es una entidad poco frecuente en pediatría, en la cual existe una limitación para la diástole cardíaca por fibrosis del pericardio. El origen etiopatogénico de esta patología es múltiple, encontrándose en primer lugar, la pericarditis constrictiva idiopática y, en segundo, la infección por Mycobacterium tuberculosis. El diagnóstico constituye un desafío clínico, ya que requiere de un alto grado de sospecha. Suele presentarse de forma oligosintomática. La presencia de edema, ascitis y alteración de la función hepática suele orientar el estudio hacia una enfermedad hepática primaria. Una cuidadosa historia clínica y examen físico, junto con estudios por imágenes adecuados, constituyen las piedras angulares del diagnóstico. El tratamiento quirúrgico realizado de forma oportuna resulta curativo en la gran mayoría de los pacientes. Se presenta el caso de un paciente de 16 años que inicia estudios por hallazgo de hepatomegalia asociada a disnea grado 1-2 en un control de salud habitual.
ABSTRACTConstrictive pericarditis is a rare entity in pediatrics in which there is a limitation for cardiac diastole due to fibrosis of the pericardium. The etiopathogenic origin of this pathology is multiple, finding idiopathic constrictive pericarditis firstly and Mycobacterium tuberculosis infection secondly. Diagnosis is a clinical challenge since it requires a high degree of suspicion. It usually presents as oligosymptomatic or with signs and symptoms of low cardiac output. The presence of edema, ascites and impaired liver function usually guides the study towards primary liver disease. A careful clinical history and physical examination together with adequate imaging studies are the cornerstones of the diagnosis. Surgical treatment is curative in the vast majority of patients. We present the case of a 16-yearold patient with hepatomegaly and dyspnea grade 1-2 found in a routine health check-up.
