We propose to examine Congenital Diaphragmatic Hernia (CDH) patients for evidence of airway inflammation as a first step to characterize the reported bronchodilator responsiveness. Airway biopsy studies are invasive and thus we propose to perform induced sputum studies to document the amount and type of inflammation present. Another ancillary non-invasive measure of airway inflammation that we will use is exhaled nitric oxide (NO). The primary objective of this study is to determine if CDH patients have any evidence of airway inflammation. The hypothesis of this study is that children with CDH do not have evidence of airway inflammation associated with bronchodilator responsiveness. Based on this information, treatment for CDH patients will hopefully be more accurate and appropriate for their specific needs.
This is the 5th in a series of physiological studies to determine the amino acid requirements of infants. There have been 4 studies to determine tyrosine, methionine, threonine and lysine requirements in infants when they are fed by parenterally (intravenously). Due to the new requirements of Health Canada for preparation of parenteral solutions, the investigators are starting the phase of the study that determines the enteral (oral) intake of threonine in 1 - 6 mo infants in the interim.
In isolated congenital diaphragmatic hernia (CDH), recurrent risk is low suggesting the occurrence of novo mutations (dominant or recessive). Our objective is to test this hypothesis by combining the search for pathogenic genomic alteration and intragenic mutations through whole exome sequencing in a homogenous group of patients.

The study is primarily a descriptive study examining the physiological, ventilatory, surgical, and recovery effects of patients ≤ 6 months of age who undergo thoracoscopic surgery and to determine the accuracy of transcutaneous CO2 (TC-CO2) and end-tidal CO2 (ET-CO2) during high frequency oscillatory ventilation (HFOV) and thoracoscopic procedures.
Congenital diaphragmatic hernia (CDH) is associated high mortality and morbidity, mainly in those cases with severe forms where there are extremely reduced lung volumes, liver herniation and decreased abnormal pulmonary vascularization. Fetal endoscopic tracheal occlusion performed between 26 and 30 weeks (standard FETO) has been shown to increase fetal pulmonary size and vascularity, and to improve infant survival in isolated severe CDH. Fetal pulmonary response followed FETO can be used to predict outcome and is dependent on the size of the fetal lung prior to the procedure. We hypothesize that performing an earlier FETO, between 22-24 weeks, fetuses with severe form of CDH will have a better fetal pulmonary response and higher chance of surviving.
This is a pilot randomised controlled trial comparing open versus thoracoscopic surgery for repair of oesophageal atresia with tracheo-oesophageal fistula or congenital diaphragmatic hernia in neonates. Thoracoscopic surgery involves insufflation of carbon dioxide into the thoracic cavity and may therefore cause hypercapnia and acidosis.
The neonatal mortality rate in cases with severe isolated congenital diaphragmatic hernia is higher than 90% due to severe pulmonary hypoplasia. Many studies have suggested that fetal tracheal occlusion may increase lung volumes and therefore reducing the risk for severe pulmonary hypoplasia and by consequence the risk for neonatal death. The main objective of the present study is to evaluate if fetal tracheal occlusion improves survival rate in those cases that are followed in our hospital, by conducing a randomized trial.
The purpose of this study is to understand the genetic causes of congenital diaphragmatic disorders (CDD), namely congenital diaphragmatic hernia (CDH), eventration and hiatal hernia. Specifically, the investigators plan to: 1. Ascertain informative families and sporadic cases with congenital diaphragmatic disorders and obtain appropriate phenotypic data and genetic material (peripheral blood and/or diaphragm tissue sample). 2. Localize the gene(s) for CDD to specific chromosomal segments using linkage analysis, and determine the role of somatic mutations in CDD. 3. Isolate and characterize genes involved in the pathogenesis of CDD. 4. Develop molecular markers that will facilitate accurate diagnosis (including prenatal diagnosis) and permit correlation of phenotypic variation with specific mutations. 5. Compare RNA-sequencing from tissue samples of children without CDH to those children with CDH.
