Filter by:This study investigates fluorescence image-guided surgery to allow precise identification of necrotic tissue both preoperatively and intraoperatively in burn patients. Furthermore, it uses a multi-model approach to elucidate the localization of ICG in inflammation and necrosis to determine how this novel use of a well-known fluorescence marker can be optimized to aid in surgical decision making. This proposal will provide the necessary data to support the design of a larger clinical trial to study the feasibility and efficacy of this technology to improve the precision of necrosis detection and removal and improve wound healing outcomes. Up to 100 participants will be on study for up to approximately 24 days.
To assess the levels of TNF- α in vitreous samples of patients with retinal vein occlusion prior to administration of intravitreal anti-VEGF and compare them to levels in vitreous samples of normal subjects so as to investigate the association of vitreous tumor necrosis factor with the pathogenesis of retinal vein occlusion.
Acute pancreatitis is one of the most common diagnoses made in gastroenterology wards worldwide which causes a great deal of pain and expense along with fatal complications. Approximately, 10-20% of patients progress to necrotizing pancreatitis that result in significant morbidity and mortality. Initial conservative management may be feasible in necrotizing pancreatitis, however the majority of patients with infected necrosis or persistent symptoms will eventually require a drainage procedure. Drainage procedures for necrotizing pancreatitis include open surgery, minimally invasive surgery, percutaneous drainage, and endoscopic drainage. In the recent years, minimally invasive approaches have largely replaced open surgical necrosectomy. Endoscopic drainage of walled off pancreatic necrosis involves creation of a transmural fistula between the enteral lumen and WOPN cavity with stent placement under endoscopic ultrasound (EUS) guidance. Furthermore, direct endoscopic necrosectomy can be performed through the fistula track. The best timing for endoscopic necrosectomy is not yet defined. A recent retrospective study suggested that immediate necrosectomy after stent placement results in earlier resolution of WOPN with fewer sessions of endoscopic necrosectomy. The aim of this study is to compare immediate vs. on-demand endoscopic necrosectomy in patients with infected WOPN who undergo EUS-guided transmural drainage of WOPN.
Evalaution of clinical success of secondary treatment for total 40 permanent incisors with failed root canal treatment with apical radiolucency. Twenty of of these permanent incisors will be treated with regenerative endodontic treatment(RET) with platelets rich fibrin PRF as intervention group vs. 20 incisors control group secondary treated with (RET) with induced blood clot (BC).
Currently during DIEP flap reconstruction, the perfusion of the flap is assessed by the clinical view of the surgeon. Identification of demarcated ischemic zones of the DIEP flap could be optimized by using fluorescence imaging with indocyanine green (ICG) in order to lower the rate of fat necrosis. This study evaluates whether intraoperative perfusion assessment with ICG fluorescence imaging causes a lower rate of fat necrosis compared to conventional intraoperative clinical evaluation of DIEP flaps.
Single-blinded randomised controlled trial comparing impingement with CT scan for manual and robotic total hip replacement. A pilot study of 50 participants.
This is a Post-Marketing Surveillance of Quadra-P anteverted stem prosthesis.
Walled-off necrosis (WON) is a pancreatic fluid collection, which contains necrotic tissue after four weeks of the onset of acute pancreatitis. Interventions are required to manage patients with infected WON, for which endoscopic ultrasonography (EUS)-guided drainage has become a first-line treatment modality. For patients who are refractory to EUS-guided drainage, the step-up treatment including endoscopic necrosectomy (EN) and/or additional drainage is considered to subside the infection. Recent evidence suggests that EN immediately after EUS-guided drainage may shorten treatment duration without increasing adverse events. In this randomized trial, the investigators will compare treatment duration between EN immediately after EUS-guided drainage versus the step-up approach in patients with symptomatic WON.
Magnetocardiography (MCG) is a promising noninvasive and accurate method for detecting myocardial ischemia. Although progress has been made in this area, there is a lack of studies using up-to-date examination instruments for the calibration of MCG analysis. This is a prospective single-center study aiming to build accurate analytical models of MCG to detect coronary lesions and myocardial necrosis. Coronary lesions are measured by coronary angiography (CAG) or coronary CTA, and are defined by both the stenosis degree and the computer-simulated fraction flow reserve. Myocardial necrosis is examined and quantified by cardiac MR. Healthy volunteers, chest pain patients who will receive CAG or CTA examination, and patients with acute myocardial infarction will be enrolled in this study.
