    ABSTRACT: This study sought to summarize the diagnostic and treatment aspects of congenital diaphragmatic eventration (CDE) in children by retrospectively analyzing their medical records to identify and understand the complications of CDE, its treatment, and to evaluate the long-term outcomes of diaphragmatic plication. The medical records of children who received treatment for CDE from January 2000 to December 2011 at the Children's Hospital of Chongqing Medical University, China were analyzed. Data analyzed included the following: age, sex, symptom, location of eventration, associated anomalies, surgical procedures, complications, and survival and follow up details after diaphragmatic plication. The medical records of 177 children (boys: 128, girls: 49, mean age: 10.28±2.35months) with CDE were included in this study. Specific symptoms of eventration of the diaphragm were reported for 86 cases; and the typical symptoms included rapid breathing, vomiting, and recurrent respiratory infections. Except for a bilateral case, all the other patients had unilateral CDE. Associated malformations were observed in 31 cases (17.5%), hypoplastic lung (10 cases) was the most common followed by congenital heart disease (9 cases), and cryptorchidism (3 cases). Interestingly, 91 patients were asymptomatic. Diaphragmatic plication was performed in all symptomatic patients (86 cases, 48.5%) and none had recurrence. Clinical symptoms of CDE varied in severity, ranging from asymptomatic conditions to life-threatening respiratory distress. Timely accurate diagnosis and treatment of symptomatic CDE could effectively resolve respiratory morbidity and reduce complications. The diaphragm plication surgery provided good results among the study population with no recurrence. Copyright © 2014 Elsevier Inc. All rights reserved.

    ABSTRACT: Respiratory syncytial virus (RSV) is the most important cause of severe, lower respiratory tract infections in infants, and RSV infections have been associated with chronic wheezing and asthma during childhood. However, the mechanism of RSV-induced airway inflammation and airway hyperresponsiveness (AHR) is poorly understood. Furthermore, there are presently neither effective vaccines nor drugs available for the prevention or treatment of RSV infections. In this study, we investigated the effect of the plant extract resveratrol as a means of preventing airway inflammation and attenuating RSV-induced AHR. Our data showed that resveratrol reduced RSV lung titers and the number of infiltrating lymphocytes present in bronchoalveolar lavage fluid (BALF) and reduced inflammation. Furthermore, resveratrol attenuated airway responses to methacholine following RSV infection and significantly decreased gamma interferon (IFN-γ) levels in BALF of RSV-infected mice. Data presented in this report demonstrated that resveratrol controlled Toll-like receptor 3 (TLR3) expression, inhibited the TRIF signaling pathway, and induced M2 receptor expression following RSV infection. These data support a role for the use of resveratrol as a means of reducing IFN-γ levels associated with RSV-mediated airway inflammation and AHR, which may be mediated via TLR3 signaling.
