Comparing Fully Covered, Self Expanding Metal Stent (FCSEMS) and Plastic Stents for EUS- Guided...
Walled-off NecrosisThis is a multi-center, single-blinded, randomized trial comparing AXIOS FCSEMS (Fully Covered Self Expanding Metal Stent) and plastic stents for EUS (Endoscopic Ultrasound)-guided management of infected and/or symptomatic WON (Walled Off Necrosis). Patients will be randomized to either FCSEMS or plastic stents for EUS-guided drainage of WON in a 1:1 manner. Following EUS-guided drainage patients in both groups will be assessed pre- procedure, pre -discharge, weeks 1, 6 and months 3, 6, 12 and 24 months. Information will also be collected from any subsequent hospital admissions related to their walled-off necrosis.
Rotational Thromboelastography Study in Tranexamic Acid and Colloid Infusion
Avascular Necrosis of Femoral HeadDegenerative Arthritis of HipColloid solution is generally used to maintain intravascular volume. It is reported to impair blood coagulation in vivo and in vitro more than crystalloid does by prolonging coagulation time and decreasing clot strength. The formed fibrin clot is more vulnerable for fibrinolysis in a case of using colloid. Dilution of plasmin in vitro with colloid enhances fibrinolysis primarily by diminishing α2-antiplasmin-plasmin interaction. Tranexamic acid is an antifibrinolytics that competitively inhibits the activation of plasminogen, by binding to specific site of both plasminogen and plasmin, a molecule responsible for the degradation of fibrin, a protein that forms the framework of blood clot. It is used to treat or prevent excessive blood loss during surgery and in other medical conditions. Gastrointestinal effect, dizziness, fatigue, headache, hypersensitivity reaction, or potential risk of thrombosis is reported as the adverse effect of tranexamic acid. We hypothesized that inhibition of plasmin by tranexamic acid after colloid administration can improve the colloid-induced clot strength impairment.
Nanodiamond-Gutta Percha Composite Biomaterials for Root Canal Therapy
Dental Pulp DiseasesDental Pulp Necrosis1 moreThe purpose of this study is to to compare root canal therapy success between two root canal filler materials: 1) gutta percha (GP), 2) gutta percha modified with nanodiamonds and amoxicillin (NDGX). Gutta percha is the current standard root canal filler material used during non-surgical root canal therapy (RCT). Gutta percha modified with nanodiamonds and amoxicillin is an investigational root canal filler material, not yet FDA approved for use as described in this study. The safety and usefulness of NDGX is being tested in this study in comparison to the current standard of care, gutta percha (GP).
Endoscopic Large Caliber Drainage vs. Complete Necrosectomy for Treatment of Walled-off Pancreatic...
Necrotizing PancreatitisThe purpose of this study is to determine optimal treatment strategies for symptomatic walled-off pancreatic necrosis( WON).
A Validated Necrosis Assay to Determine the Need for Revision Surgery in Metal-on-metal Total Hip...
ArthritisFailure of Total HipThe purpose of the study is to develop a biomarker assay to be used as a diagnostic tool for adverse local tissue reaction, or tissue necrosis, in a metal on metal total hip replacement. A convenience sample of a total of 100 hip patients will be enrolled: 50 metal-on-metal revision hips, 25 metal-on-poly revision hips, and 25 pre-operative total hips (no implant, control group) will be enrolled. Preoperative blood serum samples and intraoperative synovial fluid will be obtained from all hips and used for biomarker testing. Additionally, intraoperative assessment of tissue necrosis will be assessed.

A Multi-centre Study to Assess the Long-term Performance of the Pinnacle™ Cup With a Polyethylene-on-metal...
Rheumatoid ArthritisOsteoarthritis7 moreThe purpose of this study is to monitor the performance of the Pinnacle™ Cup with a polyethylene-on-metal bearing combination in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.
Mortality and Related Risk Factors After Hip Arthroplasty
Fracture of Neck of Femur (Hip)Femoral Head Necrosis2 moreThe patients who underwent hip arthroplasty in our hospital from January 2017 to December 2020 were reviewed. The perioperative data were collected, and then the mortality was calculated and the risk factors were analyzed.
Quantifying the Venous Congestion Curve of a Tissue Oximetry Device
Post-Op ComplicationSkin Flap NecrosisThe purpose of this research study is to measure rate of decline and pattern of tissue oxygenation using the device, ViOptix T.Ox. ViOptix probes will be secured to the arm and hand. The recording process on the ViOptix machine will begin and obtain baseline StO2 levels for 5 minutes. After 5 minutes, a blood pressure cuff will be inflated on one arm. This blood pressure cuff will be left inflated for 10-20 minutes. Every 2 minutes a pulse check or doppler exam will be performed at your wrist. Last, the cuff will be deflated and the you will be free to leave the study room.
