Active clinical trials for "Congenital Abnormalities"

Children submitted to fetoscopic in utero myelomeningocele repair using the SAFER (Skin-over-biocellulose for Anternatal FEtoscopic Repair) technique will evaluate at 30 months or more, regarding ambulation, neurodevelopment, urinary and fecal status.

: Data was collected retrospectively from six centers providing care for patients with undescended testicles from September 2017 to February 2019. All patients whose congenital anomalies of the epididymis or vas deferens were discovered incidentally during operative intervention for cryptorchidism and where photographs of the anomalies were taken were included.

The purpose of this Post Market Surveillance Validation is to document the performance and clinical outcomes of the Polaris Deformity Spinal System & Trivium 3D Spinal Deformity Correction System.

Complete DiGeorge anomaly (cDGA) is a disorder in which there is no thymus function. With no thymus function, bone marrow stem cells do not develop into educated T cells, which fight infection. Without successful treatment, patients with cDGA must remain in reverse isolation to prevent infection and subsequent death. Cultured thymus tissue with and without immunosuppression (drugs given before and after implantation) has resulted in the development of good T cell function in subjects with complete DiGeorge anomaly. This expanded access study continues cultured thymus tissue safety and efficacy research for the treatment of complete DiGeorge anomaly. Eligible participants receive cultured thymus tissue. Immune function testing is continued for one year post-implantation.

This is a study looking at advanced imaging such as PET/CT and MRI to see if they can provide a more accurate assessment of the patient with dense breasts or difficult to interpret mammograms. In addition, the ability to determine whether one or the other is more accurate or whether both together would be appropriate in this clinical situation, may be able to be measured. The MRI studies are very sensitive for detection of breast histopathology but less specific in differentiating between small low grade malignancies are more benign pathologies. Multifocal pathology can be challenging in determining site(s) for biopsy. PET scanning is specific in the measurement of metabolic glucose activity of various histopathologies and is accurate in differentiating aggressive from benign pathology in multifocal breast disease. A further drawback of PET is the lack of ability to observe lesions less than 3-4mm in diameter. In select cases the combination of MR and PET/CT is able to come to a more conclusive diagnosis - specifically with bilateral or multifocal breast disease.

The purpose of this study is to determine the incidence and clinical history of neurofibromatosis type 1-related spinal abnormalities.

The purpose of the study is to identify biological data linked to auto immune abnormalities associated with Down Syndrome.

This proposal describes a population-based case-control study of all Norwegian infants born with cleft lip or palate over a five-year period. The study will be jointly supported by the U.S. National Institute of Environmental Health Sciences (NIEHS), and the Norwegian National Institute of Public Health (SIFF) and Medical Birth Registry of Norway (MBR). Cases will be identified through the two surgery clinics that treat all clefts in Norway. Controls will be randomly selected from all live births through the MBR. Mothers will complete two selfadministered questionnaires; one regarding exposures before and during pregnancy, the other their diet during their early months of pregnancy. Biological specimens for DNA testing (blood samples, buccal swabs) will be collected from cases, controls and mothers in order to describe possible gene-environment interactions. With 750 cases and 1100 controls, this will be one of the largest and most complete field studies of facial clefting yet conducted.

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.

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.
