Active clinical trials for "Congenital Abnormalities"

To evaluate the safety and efficacy of Sirolimus in complicated vascular anomalies in Chinese children

This is a single-center, randomized, double-blind, placebo-controlled, single ascending dose, sequential-group Phase 1 study. The study will be conducted utilizing a cohort design, with sequential groups of 8 subjects. Within each dose cohort, 6 subjects will be randomized to active, and 2 will be randomized to placebo.

The aim of this study is to compare Safety, efiicacy and clinical effects of surgical versus transcatheter closure of ventricular septal defect (VSD ). The outcome of interest is success rate, residual shunts, effect on tricuspid and aortic valves, need for blood transfusion, length of hospital and intensive care unit ( ICU ) stay, complications especially complete heart block, affection of kidney functions due to the procedure length caused by Cardiopulmonary bypass in case of surgical group or by the dye used in the group of transcatheter closure.

The aim of the study is to understand the effect of spinal deformity and altered sagittal plane parameters of lumbosacral complex on acetabular cup position in THA.

This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds. Participants will have their heart sounds recorded during their regular clinic appointment after consenting to participate in this study. Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.

This study aims to investigate the effects of foot pronation exercises and arch support insoles on balance and vertical jump test in football players.

Gastrointestinal vascular malformation (GIVM), which is an important cause of acute or chronic gastrointestinal bleeding, currently lacks of effective treatment. The investigators' previous study first confirmed thalidomide treatment of GIVM bleeding was safe and effective. This prospective multi-center randomized controlled clinical trial intends to investigate the efficacy of thalidomide to the recurrent small intestinal hemorrhage due to GIVM.

This research will lead to the first evaluation of intrinsic and dynamic joint and muscle mechanics of equinus in cerebral palsy. It would provide a direct cause and effect relationship between equinus and bone deformity. Mechanical insights to the pathophysiology of the targeted muscles will lead to better understanding and, thus, to a better medical and surgical management of equinus deformity. Secondary aim will provide an important insight whether key gait parameters can be exclusively relied upon for surgical treatment planning and evaluation. In a medium-term perspective, depending upon the results of this study, dynamic MRI of the ankle joint may serve as a guiding tool for fixed equinus surgery in case of cerebral palsy.

The Ilizarov external fixator is an external skeletal fixator that is used to stabilize or lengthen the limb bones. Bone lengthen bone occurs through mechanical distraction on the long axis of the bone, thus the method of lengthening is called distraction osteogenesis. This method has been shown successful. Unfortunately, it has also been associated with a substantial number of complications. Muscle shortening and persistent weakness are among the most common complications seen in this procedure. Muscle shortening usually occurs in strong muscle groups such as the planter flexor muscles, as a result of strength imbalance between the opposing muscle groups. Shortening may persist for more than a year after the removal of the fixator and may require surgical intervention. Fortunately, muscular shortening can be prevented by splinting and physiotherapy in the form of stretching and strengthening exercise and functional training. The use of different exercises in rehabilitation can help accomplishing different therapeutic goals. Thus, the choice to use one or the other should depend on the desired treatment goals. Weight bearing (CKC) and non weight bearing (OKC) exercise has been incorporated into rehabilitation; however, the effects of these two types of exercises particularly on muscle flexibility and mechanics have never been studied systematically. Therefore, the purpose of this is to compare the effects of OKC and the CKC exercise on muscle strength, architecture and flexibility. General Hypothesis: The use of open kinetic or closed kinetic chain exercises will have no different effects on muscle function or internal organization during tibial distraction osteogenesis by Ilizarov's method Specific hypotheses There will be no difference between the effects of OKC and CKC on muscle flexibility. There will be no difference between the effect of OKC and CKC exercises on muscle strength. There will be no difference between the effect of OKC and CKC on the internal organization of muscle specifically the pennation angle, muscle thickness and fiber length. There will be no difference between the overall of OKC and CKC exercise on the functional performance of patients.

The phosphatidylinositol 3-kinase (PI3Kinase)/Protein Kinase B (AKT)/mammalian target of rapamycin (mTor) pathway plays a role on the development and the lymphatic-vascular organisations. The investigators want to study the efficacy and the safety of Rapamycin, an mTor inhibitor.
