5 Clinical Trials for Various Conditions
In a collaborative effort with the Health Research Board, the national organization for medical research in the Republic of Ireland, individuals with neural tube defects (NTDs) or facial cleft defects and their parents will be studied. With the exception of a few well-described syndromes most cases of NTDs and facial clefts are not inherited in a Mendelian fashion. Nearly all incident cases occur in families with no prior history of the defects. The observed recurrence risk in families with an NTD child is 10-12 fold higher than the general population suggesting that inherited factors modify this risk. Historically, the incidence of NTDs in Ireland was 5-8 fold higher than the USA. The aim of this study is to identify the gene(s) involved in these defects using standard genetic epidemiology approaches, transmission disequilibrium testing and gene mapping strategies. We will initially evaluate genes known to be involved in folate metabolism and pattern formation (development of the body). The major outcomes measured will be aggregate allele frequencies in case groups compared to controls. Biochemical parameters in red cells and plasma will also be measured. Comparisons will be made between the presence of genetics variants, biochemical parameters and clinical phenotype. Characterizing the genes associated with these defects should provide insight into the etiology and metabolic processes that may be involved, furthering prevention and intervention efforts.
The purpose of the study is to evaluate the safety and efficacy of devices used in patients undergoing fetoscopic neural tube defect repair.
The Genetics of Neural Tube Defects Study at the University of Miami: The University of Miami John P. Hussman Institute for Human Genomics is looking for families to participate in research to identify the genetic and environmental factors that contribute to Neural Tube Defects (NTD). Our research goal is to better understand the genetic and environmental causes of both open NTD, like spina bifida and anencephaly, and closed NTD, like lipomeningocele and tethered cord. This will eventually lead to more accurate genetic counseling and risk assessment, improved treatments, and better prevention methods. Any individual with a diagnosis of NTD and his/her selected family members can participate, if willing. Participation is free. Travel is not required. Participation involves reading and signing a consent form, providing a blood sample, a family and medical history interview, and granting the research staff permission to review the medical records of the individual(s) with NTD. We maintain the highest standards of confidentiality for all families.

The purpose of the study is to compare the maternal, fetal and neonatal outcomes of a cohort of 60 patients in whom a multilayer closure with a Durepair patch is performed with a prior cohort of patients in whom a standardized repair without patch (n = 32) was performed using the same minimally invasive fetoscopic repair technique. The hypothesis is that there will be a thicker repair (as measured by MRI at 6 weeks post surgery) and less MMC repair dehiscence and/or CSF leak with the patch repair.
The purpose of the study is to evaluate the maternal and fetal outcomes of a new technique for the fetoscopic repair of fetal MMC at Texas Children's Hospital Pavilion for Women. The investigators hypothesis is that this minimally invasive technique is feasible, and that this approach will have the same efficacy as open fetal surgery for MMC, but with significantly less maternal-fetal risk. Both mother and baby will benefit from the surgery. The fetus will have a repaired MMC defect, and the mother will not have a uterine incision (hysterotomy). A hysterotomy increases the risk of uterine rupture and requires that all subsequent deliveries are by cesarean section. There may also be a decreased risk of Pre-term Premature Rupture Of Membranes (PPROM) and prematurity when compared with the current open operation. Finally, a vaginal delivery is possible following the fetoscopic fetal surgery if the baby is shown to have a skin covered repair.
