Active clinical trials for "Congenital Abnormalities"

This study is a two periods multi-center Phase II trial, with a 6 months double-blind, placebo-controlled period followed by open label period. It will involve 20 participants with MCAP syndrome. Assessment will be performed at baseline and after 24 months of treatment and will include MRI, biological and clinical results, attention, language, and Intellectual Quotient (IQ) assessment. Appropriate neuropsychological tests will be used according to the age of patients and their level of cognitive impairment.

The purpose of this study is to evaluate the feasibility of a fetoscopic surgical technique for antenatal correction of fetal myelomeningocele. Two surgical approaches will be utilized. The percutaneous approach will be offered to participants with a posterior placenta. The laparotomy/uterine exteriorization approach will be offered to participants regardless of placental location.

The restriction of the range of motion is one of the most frequently encountered complications after the surgical procedures of the knee. While the flexion deficit is relatively well tolerated, even the small extension deficit significantly impairs the quality of life due to the increased stress on the patellofemoral joint, functional leg length discrepancy and the subsequent mechanical overload in the hip joint, lumbar spine and contralateral knee. In the majority of cases the guided physiotherapy protocol is sufficient to restore the full range of motion. In refractory cases, the treatment consists of the thorough arthrolysis of the affected knee, aiming to excise the adhesions, osteophytes and orthopaedic implants interfering with the knee range of motion. However, as the extension deficit persists, the contracture of the knee posterior capsule may develop and the sole debridement of the knee may be insufficient. In such rare cases the treatment consists of the posterior capsulotomy of the affected joint. Traditionally, this procedure was performed through the open approach. However, with the growing indications toward the arthroscopic procedures seen in recent decades, even such salvage procedures like posterior knee capsulotomy are increasingly performed through the arthroscopic approach. The aim of this study is to assess the outcomes of the arthroscopic complete posterior capsulotomy of the knee basing on the knee range of motion and functional outcomes. The primary outcome consists of the knee extension, whereas the secondary outcomes include knee flexion, knee total range of motion, The International Knee Documentation Committee Questionnaire and the Knee injury and Osteoarthritis Outcome Score.

The purpose of the study is to calculate magnitude, type of intraoperative brain shift and assess possibility of it's prediction.

The purpose of the study is to assess accuracy, advantages of functional neuronavigation and calculate safe distance from motor areas to brain tumors and vascular malformations in image-guided surgery.

This study aims to assess the feasibility to perform a fetoscopic prenatal repair of an open neural tube defect, and secondly to assess the maternal, fetal and neonatal outcomes.

To evaluate the wound healing response following nipple-areolar complex (NAC) reconstruction with a decellularized donor NAC graft (DCLNAC)

The subjects of this study are patients with non-load-bearing bone defects of the extremities who need bone grafting surgery. The patients was treated with bone graft using magnesium containing biodegradable polymer bone repair material produced by Shenzhen Zhongke Jingcheng Medical Technology Co., Ltd.. Three follow-up visits were performed at the 12th, 24th and 36th weeks after bone grafting, the clinical role for bone will be assessed.

Atrophic alveolar bone presents a unique difficulty, preventing correct implant placement and affecting long-term results. There are different techniques that are recommended to restore the proper length of the posterior ridge of the mandible and thus achieve proper form and function, one of those is distraction osteogenesis. Refinements in the technique of distraction can improve the treatment outcome and decrease postoperative complications.

A thorough analysis of the literature shows that children with clefts have a lesser oral hygiene (OH) and dental health (DH) than children without facial malformations, which leads to an increased number of tooth decay on temporary and permanent tooth and a poor gingival health due to gingivitis or periodontitis. The incidence of tooth decay is corelated with the severity of the cleft, children with bilateral cleft lip (including the alveolar bone) have a higher rate of tooth decay. Despite the fact that carious lesions are decreasing in general population, its rate remain constant in children with cleft. Children who suffer from cleft in the north-west region of France are treated within the center of competence of rare disorder in the Nantes's hospital (CCMR MAFACE); this center is a gathering of different professional health specialist (surgeon, speech specialist, gynecologist, orthodontists, pediatrician…) working together to maximize treatment for those patients from diagnosis (sometime antenatal) to adulthood. The active file of patients treated for cleft in Nantes's CHU is quite important, allowing an easy recruitment. The investigator would like to create a clinical study, assessing the impact implementing a special program to strengthen OH in patient with cleft whose follow-up is taking place in Nantes's CCMR MAFACE. It would be an epidemiologic, prospective, randomized, controlled, and monocentric study
