Active clinical trials for "Congenital Abnormalities"

Evaluation of postoperative outcomes of Chiari type I Malformation Patients at Department of Neurosurgery Assiut University Hospital .

BACKGROUND: Carpal tunnel syndrome (CTS), the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel CTs is a very common complication found in pregnancy, which is reported as high as 62% in pregnant females. The functioning of median nerve is compromised in almost all pregnant females especially during the third trimester of pregnancy, the majority may still feel some symptoms up to 3 years after delivery. Many clinicians have used LLLT on acupuncture points, which is called laser acupuncture (LA), to treat many clinical problems, such as musculoskeletal pain, lateral epicondylitis, headaches, etc. In contrast with traditional acupuncture needles, LA is a non-invasive therapy that does not cause tingling/pain during procedures Objective: to determine efficacy of laser acupuncture on electrophysiological parameters of median nerve in postpartum women

A single arm clinical trial evaluating the safety and efficacy of the second generation TEVG as vascular conduits for extracardiac total cavopulmonary connection.

A new endovascular route for the treatment of brain AVMs may be possible in some cases: Trans-Venous Embolization (TVE). The technique uses microcatheters to navigate to the draining veins of AVM, to reach and then fill the AVM nidus retrogradely with liquid embolic agents until the lesion is occluded. This technique has the potential to improve on some of the problems with the arterial approach to AVM embolization, such as a low overall occlusion rate. However, by occluding the vein first, and filling the lesion with the embolic agent in a retrograde fashion, the method transgresses a widely held dogma in the surgical or endovascular treatment of AVMs: to preserve the draining vein until all afferent vessels have been occluded. Nevertheless, the initial case series have shown promising results, with high occlusion rates, and few technical complications. The method is increasingly used in an increasing number of centers, but there is currently no research protocol to guide the use of this promising but still experimental treatment in a prudent fashion. Care trials can be designed to offer such an experimental treatment, taking into account the best medical interests of patients, in the presence of rapidly evolving indications and techniques.

A hospital-based cluster stratified randomization control study will be conducted to investigate spinal growth in Early Onset Scoliosis patients between 5 and 9 years of age. Patients must have a major coronal curve measuring over 50 degrees and be undergoing Magnetically Controlled Growing Rod treatment. We will be studying 6-week lengthening intervals compared to 16-week lengthening intervals on spinal growth within 3 years.

Two cohorts are being studied based on leptin levels. Cohort A is composed of patients with baseline leptin <8.0 ng/mL and Cohort B is composed of patients with baseline leptin 8.0 to ≤20.0 ng/mL The primary objectives will be evaluated for patients in Cohort A only: To evaluate the effect of REGN4461 on fasting triglycerides (TG) in patients with elevated baseline fasting TG To evaluate the effect of REGN4461 on hyperglycemia in patients with elevated baseline Hemoglobin A1c (HbA1c) The following secondary objectives of the study will be evaluated for Cohort B and for the combined set of Cohorts A plus B: To evaluate the effect of REGN4461 on fasting TG levels in patients with hypertriglyceridemia To evaluate the effect of REGN4461 on glycemic control in patients with hyperglycemia The following secondary objectives of the study will be evaluated for Cohorts A and B separately, and for the combined set of Cohorts A plus B: To evaluate the effect of REGN4461 on liver fat in patients with hepatic steatosis To evaluate the effect of REGN4461 on hunger To evaluate safety and tolerability of REGN4461 To characterize the concentration profile of REGN4461 over time To assess immunogenicity to REGN4461

In this study, we investigate the safety and efficacy of topical sirolimus in the treatment of superficial complicated vascular anomolies.

Evaluation of the safety and efficacy of the reSept ASD Occluder to treat patients with clinically significant secundum atrial septal defect

The aim of the study is to evaluate the efficacy and safety of sirolimus (oral form), to decrease the volume and symptoms due to superficial arteriovenous malformations (AVM). Sirolimus has properties that reduce the activity of the immune system (immunosuppressant), to fight against the proliferation of cancer cells (anti- tumor) and also reduce the proliferation of blood vessels (anti -vascular). Sirolimus is primarily used in transplant patients to prevent organ transplant rejection. Many animal and laboratory studies were carried out and demonstrate in particular the activity of sirolimus on vessels. It is this anti- vascular effect that could help treat arteriovenous malformations.

Objectives: The aim of this randomised controlled clinical trial is to evaluate surgical accuracy and efficiency of computer-assisted jaw reconstruction using 3D-printed patient-specific titanium surgical plates versus conventional plates. Hypothesis to be tested: The investigators hypothesize that compared to conventional surgical plates, 3D-printed patient-specific surgical plates improve surgical accuracy and efficiency of computer assisted jaw reconstruction. Design and subjects: This is an open-label, prospective, double-arm, and single-centre randomised controlled clinical trial. Patients with maxillary or mandibular neoplastic, inflammatory and congenital diseases who require immediate or secondary reconstructive surgery will be invited to participate in the study. Study instruments: 3D-printed patient-specific titanium surgical plates and conventional plates. Main Outcome Measures: The primary endpoint is the accuracy of reconstruction. The secondary endpoints include the accuracy of osteotomy, reconstruction time, total operative time, intraoperative blood loss, length of post-operative hospital stay, and postoperative adverse events. Data analysis: The accuracy parameters, reconstruction time, total operative time, intraoperative blood loss, length of post-operative hospital stay will be presented as mean values with standard deviations. The post-operative adverse events will be calculated and presented as frequency with standard deviation. Expected results: This randomised control trial will prove improved accuracy and efficiency of reconstruction using 3D printed patient-specific titanium surgical plates. This study is expected to provide high-level evidence to push forward the popularity of using 3D medical printing technology in surgical field.
