Filter by:This trial will evaluate the efficacy and safety of the modified Blalock-Taussig shunt (MBTS) compared to the right ventricle to pulmonary artery (RV-to-PA) shunt; compare the effect of the MBTS to that of the RV-to-PA shunt on the incidence of death or cardiac transplantation at 12 months post randomization; and compare the effect of the two shunts on intensive care unit (ICU) morbidity, unintended cardiovascular interventional procedures, right ventricular function, tricuspid valve regurgitation, pulmonary artery growth, and neurodevelopmental outcome.
Ribavirin should be avoided during pregnancy and during the 6 months before pregnancy in both the female and the male sexual partner. If a pregnancy occurs and is reported to the Ribavirin Pregnancy Registry, the Registry will follow the pregnant woman throughout pregnancy. The Registry will also follow the infant until 1 year of age. The goal of the Registry is to learn more about the effects of ribavirin on pregnancy and the risk for birth defects. Pregnant women exposed to ribavirin, either by taking ribavirin (during pregnancy or 6 months before pregnancy) or through a male sexual partner (who took ribavirin during the female partner's pregnancy or during the 6 months before pregnancy), are encouraged to contact the Registry.
This study will evaluate the efficacy and safety of angiotensin converting enzyme inhibition (ACE-I) therapy for the treatment of mitral regurgitation (MR).
This study will evaluate the efficacy and safety of administering an angiotensin converting enzyme inhibitor (ACE-I) (enalapril) to infants with a functional single ventricle. The study will also compare the effect of ACE-I therapy to placebo on somatic growth and compare the effect of ACE-I therapy to placebo on signs and symptoms of heart failure, neurodevelopmental and functional status, ventricular geometry, function, and atrioventricular (AV) valve regurgitation. In addition, the study will determine the relationship between genetic polymorphisms linked to ventricular hypertrophy (enlarged heart) and the response to ACE-I therapy and compare the incidence of adverse events in subjects treated with ACE-I with those in subjects treated with placebo.
Cleft lip and palate are a significant component of morbid human birth defects in the developing world. This study measures the impact of having a child born with a cleft lip on subsequent maternal/infant family health, and whether frequent pediatric care compared to standard pediatric care will reduce neonatal mortality in children born with cleft lip and palate.
Feeding difficulties and airway related consequences contribute significantly to the infant mortality and morbidity. Some of these problems may be dependent on neural control and muscular function. Prematurity, congenital anomalies and perinatal depression represent three important conditions in infants, that may have feeding and airway difficulties.Development of motility of the foregut and the adaptation during normal and disease in developing infants is unclear.
This study will examine blood or other tissue samples from patients with Fraser syndrome and patients with Fryns syndrome to try to identify the gene responsible for these diseases. Fraser syndrome is characterized by congenital abnormalities including cryptophthalmos (lack of eyelid formation), syndactyly (webbed fingers or toes) and abnormal genitalia. Patients may also have abnormalities of the nose, ears and larynx (voice box), cleft lip or palate, and kidney agenesis. Fryns syndrome is characterized by hernia through the diaphragm, cloudy cornea, coarse facial features, cleft lip or palate, abnormal fingers and toes, heart, kidney and brain malformations and hydrocephalus (accumulation of fluid around the brain). This protocol consists of laboratory study only; it does not involve patient care or patient counseling. Patients with Fraser syndrome or Fryns syndrome are eligible for this study. Parents and healthy siblings of patients will also be included for genetic study, and parents of children with undiagnosed multiple congenital anomalies syndromes will be included for comparison study. Participants will provide a blood sample (about 8 to 10 teaspoons from adults; 1 to 3 teaspoons from children) or sample of skin cells collected by swabbing the inner surface of the cheek. Some patients may undergo a skin biopsy, in which a small skin sample (about 1/8-inch in diameter) is surgically removed. The tissue samples will be used to obtain DNA (genetic material) for laboratory testing. A permanent cell line-a collection of cells grown in the laboratory from the original tissue specimen-will also be established to enable additional testing in the future.
Primary Hypothesis: Gulf War veterans will have an equal prevalence or mean level of the following medical and psychological conditions frequently reported in the literature compared to a control group of nondeployed veterans: (1) chronic fatigue syndrome, (2) fibromyalgia, (3) post-traumatic stress disorder, (4) neurologic abnormalities, including peripheral neuropathy and cognitive dysfunction, and (5) general health status.
This is a study to determine the safety and efficacy of liothyronine sodium/triiodothyronine (Triostat), a synthetic thyroid hormone, when given to infants with congenital heart disease during cardiopulmonary bypass surgery.
This project is designed to establish whether pesticides or other environmental agents have a role in the excess birth defects identified in the Red River Valley of Minnesota. In this human study, laboratory based health parameters will be used to key in health survey data. In vitro data will be developed to mechanistic information. Concordant results among these study features will provide a weight of evidence approach.
