Active clinical trials for "Necrosis"

This is a national multi-center, prospective surveillance study in patients with suspected acute coronary syndrome. Eligible patients must present to one of the participating Emergency Departments within 24 hours from the time of symptom onset. Approximately 2000 patients >18 and <85 years of age are planned to be enrolled. Upon enrollment in the Emergency Department, a venous blood sample will be obtained from each patient for analysis. The patient's diagnostic work-up, treatment and disposition will continue per the standards of the treating institution. Results will be recorded for ECGs, any cardiac biomarkers measured at the site and any follow-up cardiac objective tests performed for evidence of coronary artery disease and/or myocardial damage (exercise treadmill, coronary angiography, cardiac thallium or technetium scintigraphy, etc). The Principal Investigator at each site will evaluate the results of the diagnostic cardiac tests performed for that patient to determine whether each patient enrolled at their site has a final diagnosis of ACS. The status of each patient will also be assessed at 1 month and 6 months after enrollment for intercurrent Major Adverse Cardiac Events (MACE), including myocardial infarction, cardiac revascularization and death.

This study is to investigate if there has been a shift in treatment with tofacitinib, assessing real world patient data and entered in the Corrona registry between 2016 and 2020.

Epipericardial fat necrosis is a benign and self-limited condition that mainly curses with acute pleuritic chest pain and therefore must be an important differential diagnosis for patients in emergency department (ED). The knowledge of characteristics symptoms and correct management may avoid misdiagnosis or mistakes with other severe conditions like pulmonary embolism, pericarditis or acute coronary disease. Despite the importance of this entity, only fewer than 40 cases have been reported since 1957, when the condition was first described. We have seen a couple of similar cases in our institution during a short period of time, and we suspect that these numbers doesn't mean the real prevalence of epipericardial fat necrosis, so maybe this condition could be underdiagnosed. Instead, there isn't a study that tried to estimate an incidence of this entity.

The purpose of this study is to evaluate the prognostic influence of light rheography measurement at the fingertips from subjects with secundary Raynaud syndrome.

Brain imaging tests are routinely used to detect the presence of a brain tumor or to evaluate the response to treatment. Sometimes the images obtained are not specific and the only way to establish a diagnosis is by obtaining a tissue sample. The hypotheses of the study is to determine if multimodal MR technique will provide tissue signatures that differentiate between tumor progression and treatment related necrosis in high grade glioma patients.

The investigators,according to the eligibility criteria,plane to choose 80 elderly anticipates who will undergo selective hip replacement surgery.This participants will be randomly divided into 2 groups:light anesthesia depth group(L Group) and deep anesthesia depth group (D Group).Before anesthesia induction,each participant will be given lumbar plexus and sciatic nerve block in order to control pain of interoperative and postoperative.During operation period,the L Group will be kept in light anesthesia depth(BIS:50-60),while the D group will be kept in deep anesthesia depth(BIS:35-45)--The BIS values in the range of 30-60 have been recommended in general anesthesia.After operation,a PCIA(patient controlled intravenous analgesia) analgesia pump will be given to each participant to control postoperative pain. The investigator will evaluate the mental state of participant with MMSE(mini-mental state examination) before surgery and review each participant with a CAM-CR for 3 days after surgery to assess the situation of postoperation delirium.intraoperative awareness,postoperative pain will also be investigated in postoperative days 1, 2, 3.

Revision total hip replacement arthroplasty is a surgery having intra- and postoperative substantial blood loss. The investigators will investigate the relationship between the various hematologic variables and postoperative bleeding volume.

The goal of this observational study is to compare postoperative results between patients who had total hip arthroplasty (THA) with and without the use of a computer navigation program. The main questions this study aims to answer are: Can using computer navigation produce better THA implant placement? Can using computer navigation make surgery more efficient? Participant data collected include their postoperative x-rays and total operative time.

Flap reconstruction is utilised increasingly for repair of skin and soft tissue defects following pelvic exenteration. Many methods have been proposed but the outcomes associated with each remain largely unknown and the choice dependant on surgeon preference and patient/ disease characteristics. This review sought to assess the preferred methods for perineal reconstruction following pelvic exenteration by retrospectively assessing the outcomes associated with each at an international, multi-centre level.

Displaced, multi-part intracapsular, proximal humerus fractures represent a major challenge for patients and orthopedic surgeons. Proximal humerus fractures represent the third most common fracture after hip and distal radius fractures, and more than 20% of these fractures meet operative indications. Unfortunately, one of the major complications of these fractures is the development of avascular necrosis (AVN), or death of the bone as a result of the loss of blood supply to it. Currently, the ability to predict AVN is limited. The purpose of this study is to determine if computed tomography imaging can identify a quantifiable predictor of AVN following this type of humeral fracture.
