Filter by:There are still a large number of severe spinal deformity cases which would keep progressing without treatment. These patients not only have severe appearance deformity, but also suffer from cardiopulmonary compression, reduced abdominal volume, and even spinal cord injury. It is crucial to provide safe and effective surgical intervention for these patients. The corrective surgery with 3-column osteotomy is reported to be an effective surgical strategy for severe spinal deformity. However, due to the great corrective stress on the rods, there is an increased number of patients requiring revision surgery due to rod fracture (3.7%-15%). In patients with 3-column osteotomy, the osteotomy area and the upper and lower adjacent segments are mostly stress-concentrated areas, and the rod is prone to fatigue fracture. Therefore, it is necessary to reinforce the osteotomy area and adjacent segments to reduce the risk of rod fracture. Our previous study found the risk of rod fracture could be reduced by using satellite rods with duet connectors or dominos. However, in the traditional satellite rod technology, the connection of the main rod and the satellite rod rely on the traditional single slot screw and duet connectors. The two are separated and not a whole in the mechanical structure. The stability of the fixation is relatively insufficient, and stil deserves room for improvement. Based on the traditional duet connectors, we further invent a novel dual-headed pedicle screw, which is an combination of traditional single slot screw and duet connector. Compared with the traditional duet connector, the novel dual-headed pedicle screw theoretically has stronger stability between the main rod and satellite rod, due to its integration of screw and connector. Hence, the purpose of this study is to verify the strong stability of the novel dual-headed screw by biomechanical study in cadavers performed with long spinal fusion (T12-pelvis) with L3 pedicle subtraction osteotomy (PSO). And to further investigate its effectiveness in severe adult spinal deformity patients receiving corrective surgery with PSO. If the biomechanical properties and clinical effects of the novel dual-headed screw have been confirmed, the promotion of the product has great prospects in the world. The severe spinal deformity patients would benefit from this study when they receive spinal corrective surgery with 3-column osteotomy, using satellite rods technology by this novel dual-headed screw.
The GAP study is a randomized controlled trial that aims to determine the feasibility and efficacy of the "Incredible Years Autism Spectrum and Language Delays" (IY-ASLD®) intervention for families of children with developmental problems from a genetic basis. It is a multicentric trial where families will randomly be assigned to the intervention group or to a control group (they will follow their usual treatment). The intervention will be carried out in an online format, and it will involve 22 weekly group sessions. The results of The GAP study will help clinicians and policy makers in guiding towards evidence-based treatment options for these particularly vulnerable group of infants.
The present study aims at: A. The main outcome is to compare preoperative and postoperative visual analog scale VAS from 0 to 10 of maximum perceived pain in ladies with OMAs. 1. description of clinical presentation and percentage of OMAs in relation to other Mullerian anomalies 2. description of different subtypes and its percentage. 3. description of the corrective procedures and their short-term outcomes.
In this study, the investigators seek to describe the normal 3D hip joint morphology in asymptomatic volunteers and compare it to various hip joint deformities. Asymptomatic volunteers will be asked to undergo a non-contrast MRI of the hip at 3 Tesla, utilizing a high-resolution morphologic 3D sequence (3D T2 DESS) that enables the segmentation of labrum and cartilage. 3D morphological parameters of the asymptomatic group will subsequently be compared with the 3D morphological parameters of patients with hip deformities, which were collected as part of a previous retrospective study.
Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European Registry for AAOCA (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres.
The purpose of this study is to determine whether a posterior fossa decompression and duraplasty with or without tonsil manipulation results in better patient outcomes with fewer complications and improved quality of life in those who have Chiari malformation type I and syringomyelia.
Evaluation of postoperative outcomes of Chiari type I Malformation Patients at Department of Neurosurgery Assiut University Hospital .
This is a Phase 2, multicenter, double-blind, sponsor unblinded, placebo-controlled, single-dose clinical study of CRD-4730 to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of CRD-4730 when administered as single oral doses to participants with Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). The study will have 2 cohorts in which participants with CPVT will participate in a 3-period, randomized 2-sequence study. Each participant will receive 2 different doses of CRD-4730 and 1 dose of matching placebo, with each study drug administered as a single dose.
The Congenital Heart Disease Physical Activity Lifestyle Intervention Study (CHD-PALS) V.2 seeks to determine the efficacy of a lifestyle intervention program for adolescents and young adults (AYAs) with congenital heart disease (CHD). This trial was adapted from the original CHD-PAL trial to continue improving cardiovascular outcomes for transition-aged CHD survivors.
This study is a randomized block trial designed to evaluate the effectiveness of a breastfeeding behavioural intervention program for mothers of infants with congenital heart disease (CHD). The purpose of this study is to compare exclusive breastfeeding rates, changes in weight-for-age z-scores (ΔWAZ) and height-for-age z-scores (ΔHAZ), and maternal breastfeeding behaviour between the intervention group and the control group at 1, 3, and 6 months of age.
