Filter by:The research purpose is to determine if thymus transplantation with immunosuppression is a safe and effective treatment for complete DiGeorge anomaly. The research includes studies to evaluate whether thymus transplantation results in complete DiGeorge anomaly subjects developing a normal immune system.
The study purpose is to determine if cultured thymus tissue implantation (CTTI) (previously described as transplantation) with tailored immunosuppression based on the recipient's pre-implantation T cell population is a safe and effective treatment for complete DiGeorge anomaly. This study will also evaluate whether cultured thymus tissue implantation and parathyroid transplantation with immunosuppression is a safe and effective treatment for complete DiGeorge anomaly and hypoparathyroidism.
This is an observational, prospective cohort study describing pregnancy outcomes in women with pre-existing (prior to pregnancy) type 2 diabetes who have been exposed to any formulation of exenatide during pregnancy. The pregnancy registry will compare the occurrence of the pregnancy outcomes of interest with those collected from a prospective group of women with pre-existing type 2 diabetes who have been exposed to one or more antidiabetic medications other than exenatide during pregnancy. Insulin exposures are acceptable in both groups but must be in addition to one or more other antidiabetic medications in the non-exenatide group. The primary study objective is to evaluate the percentage of major birth defects (i.e., those that caused significant functional or cosmetic impairment, required surgery, or were life-limiting) following use of exenatide during pregnancy for treatment of type 2 diabetes compared to the percentage of major birth defects following use of one or more antidiabetic medications other than exenatide during pregnancy for treatment of type 2 diabetes. The secondary objectives of the Exenatide Pregnancy Registry are to evaluate the percentage of other adverse pregnancy outcomes (e.g., spontaneous abortion, stillbirth, preterm birth) and any potential impact of exenatide use during breastfeeding among pregnancies or births in women who used exenatide for pre-existing type 2 diabetes: This study is being conducted in the United States (US). Enrollment in the Registry is voluntary. The Exenatide Pregnancy Registry is sponsored by AstraZeneca and is managed by INC Research, LLC. The scientific conduct and analysis of the Registry is overseen by a Registry Review Committee (RRC) consisting of experts in maternal and fetal medicine, teratology/genetics, epidemiology, type 2 diabetes in pregnancy and/or pediatrics.
To develop a non-invasive, simple and affordable, measurement technique to differentiate hemangiomas from subtypes of VMS. The purpose of this study is to determine the best office based diagnositc instrument for differentiating the subtype of vascular lesions. The instrument must be simple and affordable so it can be used by primary car physicians in the doctor office. The procedure will be based on non-invasive and unharmful measurements that will be compared to the diagnosis from specialized physicians in this field and the final pathology.
PURPOSE The purpose of this study is to learn more about multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT). MLT is a rare vascular disorder characterized by multiple congenital skin and visceral lesions, profound thrombocytopenia, and gastrointestinal bleeding. The skin lesions may appear red, brown or blue, often misdiagnosed as hemangiomas. The gastrointestinal tract, liver, and lungs are the most common internal organs involved. The severe thrombocytopenia (low platelets) is believed to be the result of platelet trapping within the skin and visceral vascular lesions. Severe and chronic gastrointestinal bleeding is common during infancy and early childhood. Although a relatively newly described entity, MLT was likely previously reported as hemangiomas, blue rubber bleb nevus syndrome, diffuse hemangiomatosis, Kasabach-Merritt phenomenon, and hereditary hemorrhagic telangiectasia. The term cutaneovisceral angiomatosis with thrombocytopenia is also a term used for this same disease. This study is a longitudinal cohort study of MLT to collect detailed clinical data on the distribution of disease, disease severity, and complications. This data will be used to create diagnostic criteria and an evaluation protocol for infants with this disease
One purpose of this study is to determine whether the amount of cultured thymus tissue implanted into DiGeorge anomaly infants has any effect on the immune outcome. Another purpose of this study is to determine whether parental parathyroid transplantation (in addition to cultured thymus tissue implantation (CTTI) can help both the immune and the calcium problems in DiGeorge infants with hypocalcemia.

This study focuses on women undergoing termination of pregnancy for fetal anomalies (TOPFA). Psychological consequences of such terminations may be even greater than those associated with spontaneous losses of pregnancy because of shame and guilt which can result in social isolation. Currently, there is little support for women after they have left hospital. In this study, 50 TOPFA women will be randomly assigned to an intervention group and 50 to a control group. By completing four questionnaires at the time of induction of labour, total sample will be assessed for depression, stress and "hardiness"; they will be reassessed at 3, 6, and 12 months. Total sample will be interviewed by phone at 6 and 12 months. We hope to determine whether a telephone-based intervention (a biweekly supportive call) can decrease the emotional distress experienced by women undergoing termination of pregnancy.
Phase I of the study (motion and quality assurance [QA] study) is being used to determine intrafraction target motion and define quality assurance procedures for single fraction spinal radiosurgery. The Phase II portion of the study is being used to estimate the palliative response (pain or relief of neurologic symptoms) and local control for single fraction radiosurgery delivered with TomoTherapy and to assess the acute and late toxicity of spinal radiosurgery.
Since Chiari malformation is a common disease, many patients require surgical operation to relieve pressure from the back portion of the skull. The purpose of this research is to compare two different materials that are routinely used to repair the opening in the brain covering during the surgery on the back portion of the skull in patients with symptomatic Chiari Malformation. None of the materials used in this study nor any procedures are experimental.
The staged surgical pathway to treat children with single ventricle heart defects culminates with the Fontan operation. In this procedure, systemic venous return is rerouted directly to the pulmonary arteries, which serves to separate the systemic and pulmonary circulations. Although mortality following the Fontan operation is now uncommon, early postoperative morbidity including prolonged postoperative chest tube drainage and hospitalization remains significant. The efficacy of empiric inotropic, vasodilator and neurohumoral-inhibitory therapies in the perioperative period is unknown and practice varies widely between centers. The investigators will propose a single-center, randomized, double-blind, phase II clinical trial in children undergoing Fontan surgery. The investigators plan to compare the effects of perioperative nesiritide, milrinone and placebo infusions on the early postoperative clinical course and neurohumoral profile. The investigators hypothesize that, when compared to the milrinone and placebo groups, the nesiritide group will have more days alive and out of the hospital within the first 30 days after surgery.
