Active clinical trials for "Congenital Abnormalities"

OBJECTIVES: I. Identify latent hypoparathyroidism in normocalcemic adult survivors with repaired conotruncal cardiac defects, by evaluating parathyroid gland secretory function after induced hypocalcemia. II. Determine the relationship of parathyroid hormone secretion to microdeletions in the same region of chromosome 22q11 as found in patients with DiGeorge anomaly.

The objective of this study is to discover the genes responsible for the development of hereditary cataracts in families. A cataract is clouding of the lens of the eye that obstructs the passage of light and may impair vision. Information from this study may provide a better understanding of why hereditary cataracts form and perhaps lead to the development of a test that can predict who will likely be affected and to what degree. Patients or family members of patients with inherited cataracts who participate in this study will be asked questions about their family history, especially concerning eye disease or cataracts, and a family tree will be drawn. They will undergo a complete eye examination, including photographs to document the clarity or opacity of the lens. In addition, a small blood sample will be drawn for use in gene mapping studies of inherited cataract.

The aim of this retrospective longitudinal study was to describe a key factor in the prenatal diagnosis of isolated cleft palate on the axial transverse view, in order to provide better understanding, detection and diagnosis of this anomaly.

Gestational sonographic follow up may find some brain malformations. The trial is about to characterize these findings and correlate with the immediate postnatal findings.

The purpose of this study is to compare the use of the Micro Vascular Plug (MVP) system and other embolic devices in treatment of PAVMs. Pulmonary Arteriovenous Malformations (PAVMs) are abnormal connections between the pulmonary vein and the pulmonary artery. This affects blood flow between the heart and lungs which puts patients at risk of stroke, brain abscess, hypoxia and even sudden death. The standard treatment of PAVMs is embolization. Embolization is the placing of an embolic (synthetic agent) into a blood vessel to block blood flow. The embolic is inserted via a catheter into the blood vessel. Detachable coils are the most commonly used embolic in the treatment of PAVMs. Despite long procedure times, numerous coils that are often required to occlude a single PAVM and recanalization rates ranging from 5% to 15%, the most widely used embolic device is still the detachable coil.

This study aims to validate a non-invasive method of chromosomal screening (NICS), based on the Multiple Annealing and Looping Based Amplification Cycles- Next-generation Sequencing (MALBAC-NGS) technology, in order to determine the chromosomal endowment of a blastocyst from the DNA of the embryonic culture medium. The chromosomal status of the embryo from an embryo biopsy of trophoectoderm will be established (usual clinical practice), the chromosomal endowment from the DNA of the embryonic culture medium will be determined, and the results using the NICS and the conventional invasive method (Preimplantation Genetic Testing for Aneuploidy [PGT-A]) will be compared.

Agenesis of the corpus callosum (ACC) is one of the most frequent cerebral malformations and is now diagnosed prenatally in most cases. Prenatal counseling is then challenging because of uncertain neurodevelopmental outcome, depending on the genetic cause of ACC. Our purpose is to evaluate the feasibility of sequencing known genes responsible for ACC by whole exome sequencing (WES) in trio (fetus and both parents) when ACC is diagnosed during the pregnancy, in order to provide complete and loyal information on the intellectual prognosis for the fetus.

Thanks to the evolution in knowledge and technical advances in premature newborn intensive care, the survival of very premature infants is now possible. However, prognosis remain sometimes uncertain. In 2011, the Epipage 2 study showed a significant improvement as compared with the 1997 Epipage1 study with a decrease in mortality and an increase of the survival rate without severe morbidity of 14% for preterm babies born between 25 and 29 weeks and 6% for babies born between 30 and 31 weeks. However, surviving babies without initial major deficiencies, may later show problems in terms of growth, sensory - motor and/or neuro-psychologic development. This untoward evolution lead to social and family interaction disorders and school difficulties. In this context, a perinatal care network was created for each Region in France, making it possible to take care of these vulnerable children early on and all along their development. A retrospective study will evaluate 97 pre-term babies born before 33 weeks in 2012 and who are taken care of at Nancy as part of the Lorraine regional network program "Rafael" until they are 7 years old. The objective is to evaluate objectively the neurocognitive and school abilities of these children at the age of 7. At 8 years of age, a secondary measure of outcome will be the impact of the eventual neurocognitive consequences on the quality of their family life, on the behavior of the child and the parents' feelings. This way more options to improve the way they are taken care of will be available.

The aim of the study is to determine the prevalence, describe the types and risk factors of congenital anomalies among newborns admitted to Neonatal Intensive Care Unit (NICU) of Assiut University Children Hospital (AUCH). It is a prospective and a case control study was performed and screening of the newborn admitted at NICU of Assiut University Children Hospital during the period of 6 months from 1-12-2017 to the end of 5-2018 the sample was 346 newborns, 173 cases and 173 control. Data were collected using a record checklist and an interviewing questionnaire. Conclusion: The prevalence of congenital anomalies was 22.97%. The most common anomalies were gastrointestinal anomalies (GIT), musculoskeletal anomalies, multiple anomalies and circulatory system anomalies. The risk factors were consanguineous marriage, positive family history, urban areas, full-term and singleton pregnancies.

This study aims to evaluate the accuracy of a newly developed mobile application versus the conventional method of cephalometric analysis in the diagnosis of dental and skeletal deformities among pre-adolescent patients.
