Active clinical trials for "Hernia, Diaphragmatic"

We wish to use the images a mother would have done as part of her normal medical care and make both 3D animations and 3D models of the baby and it's CDH. This will both help the parents see what the problem is and also allow the surgeons, who will operate on the baby once it has been born, to see the size of the hole and what organs are in the wrong place.

The goal of this study is to identify genes that convey susceptibility to congenital diaphragmatic hernia in humans. The identification of such genes, and examination of their structure and function, will enable a delineation of molecular pathogenesis and, ultimately, prevention or treatment of congenital diaphragmatic hernia. There are many different possible modes of inheritance for congenital anomalies, including autosomal dominant, autosomal recessive, and multifactorial. Multi-factorial inheritance is responsible for many common medical disorders, including hypertension, myocardial infarction, diabetes and cancer. This type of inheritance pattern appears to involve environmental factors as well as a combination of genetic variations that together can predispose to or produce congenital anomalies, such as congenital diaphragmatic hernia. Our study is designed to establish a small, well-defined genetic resource consisting of 1) Nuclear families suitable for linkage analysis by parametric,non-parametric (e.g. sib pairs, TDT) and association techniques, 2) Individuals with congenital diaphragmatic hernia who can be directly screened for allelic variation in candidate genes, and 3) Individuals who can serve as controls (are unaffected by congenital diaphragmatic hernia). Neonates and their families will be collected from homogenous and heterogeneous populations. By characterizing diverse populations, it should be possible to increase the likelihood of demonstration of genetic variation in selected candidate genes that can then be used in association and linkage studies in individual subjects with congenital diaphragmatic hernia.

The imaging manifestations of diaphragmatic hernia and diaphragmatic distension were retrospectively analyzed and summarized, combined with the surgical findings, to summarize the differences in indirect signs of diaphragmatic hernia and diaphragmatic distension, so as to achieve the purpose of differential diagnosis.Research contents: (1) To summarize the characteristics of indirect imaging signs in patients with diaphragmatic hernia, to sum up the incidence of each sign, to find new signs and the prognosis of each sign; (2) Summarize the characteristics of indirect imaging signs in patients with diaphragmatic distension, summarize the incidence of each sign, and search for new signs and the prognosis of each sign; (3) To summarize the differences in indirect signs of diaphragmatic hernia and diaphragmatic distension, as well as the differences in their incidence, and combined with their surgical findings, to summarize their image identification points

Congenital diaphragmatic hernia (CDH) occurs when the diaphragm fails to fully fuse and leaves a portal through which abdominal structures can migrate into the thorax. In the more severe cases, the abdominal structures remain in the thoracic cavity and compromise the development of the lungs. Infants born with this defect have a decreased capacity for gas exchange; mortality rates after birth have been reported between 40-60%. Now that CDH can be accurately diagnosed by mid-gestation, a number of strategies have been developed to repair the hernia and promote lung tissue development. Fetal tracheal occlusion is one technique that temporarily closes the herniated area with the Goldvalve balloon to allow the lungs to develop and increase survival at birth. This is a pilot study of a cohort of fetuses affected by severe CDH that will undergo FETO to demonstrate the feasibility of performing the procedure, managing the pregnancy during the period of tracheal occlusion, and removal of the device prior to delivery at BCM/Texas Children's Hospital (TCH). It is anticipated that fetal tracheal occlusion plug-unplug procedure will improve mortality and morbidity outcomes as compared with current management, but this is not a primary endpoint of the feasibility study. We will perform 20 FETO procedures on fetuses diagnosed prenatally with severe and extremely severe CDH.

The purpose of this study is to test if sildenafil is effective in the treatment of infants with severe congenital diaphragmatic hernia (determined by the presence of prolonged pulmonary hypertension or prolonged oxygen supplementation on mechanical ventilation), as measured by the estimated pulmonary artery systolic pressure following treatment.

The objective of this study is to evaluate the use of 2 different types of biosynthetic material for the repair of congenital diaphragmatic hernia. The research question is: what is the best material for repairing large congenital diaphragmatic hernias? The primary outcome variable is recurrence.

The purpose of this phase 2 limited study is to examine whether prenatal intervention correct the lung underdevelopment associated with severe diaphragmatic hernia.

The purpose of this study is to compare the efficacy of oral and rectal omeprazole treatment in infants with gastroesophageal reflux due to esophageal atresia or congenital diaphragmatic hernia.

The study has been designed to investigate the effect of 12 weeks of using virtual reality based exercises on pulmonary functions, exercise capacity, functional performance, and quality of life in children with surgically-repaired congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) is a severe birth defect, with a prevalence of 1:2000 to 1:3000 live births where a defect in the diaphragm results in, herniation of the abdominal contents into the chest with subsequent compression of the intrathoracic structures and respiratory insufficiency after birth. Respiratory insufficiency is managed with intubation and mechanical ventilation. In addition to managing respiratory insufficiency, intubation prevents entrainment of air into the intestines and further compression of the lungs and heart. Resuscitation of infants with CDH also involves placement of a nasogastric tube (NG) into the stomach for removal of entrained air and secretions. As part of routine resuscitation in infants with CDH intubation and NG tube placement are performed after the delivery personnel separates the baby from the placenta by cutting the umbilical cord. This study will assess the feasibility, maternal and fetal tolerance and the optimal approach to performing these initial steps of resuscitation with an intact umbilical cord. The investigators have randomly chosen 10 maternal and infant with congenital diaphragmatic hernia dyads to demonstrate feasibility as well as determine pitfalls and difficulties and the optimal approach to a complex resuscitation with an intact umbilical cord.
