To compare the effects of early (within 24 hours) and delayed (exceed 24 hours) epidural decompression surgery on the recovery of spinal nerve function in patients with acute spinal cord injury (complete and incomplete) at postoperative 6 months.
Hypothesis: Diagnostic ultrasound is an appropriate screening test for acute stress fracture in the lower extremity and is superior to x-ray. Primary Aims: To determine if diagnostic ultrasound is an appropriate screening test with high sensitivity and at least moderate specificity for the identification of acute stress fractures of the lower extremity. Methods: In this double-blind, prospective clinical study, subjects (age 14 years and up) suspected to have an acute stress fracture of the lower extremity will be recruited from the Sports Medicine clinic at the University of Virginia Health System in the Department of Physical Medicine & Rehabilitation. Subjects will undergo the traditional diagnostic algorithm including screening x-ray as part of standard care. Subjects will then undergo a confirmatory MRI of the region of concern if the initial x-ray was negative as part of standard care. Any subject who does not require an MRI for clinical purposes (initial X-ray was positive) will have one completed for research purposes. All subjects will also undergo diagnostic ultrasound performed by a separate, blinded physician competent in diagnostic ultrasound for research purposes. A statistician in the Department of Public Health at the University of Virginia will be performing statistical analysis during data analysis. Findings will be analyzed using a McNemar chi-square test to evaluate for significant differences between the sensitivities of ultrasound and x-ray.
This is a multi-center, randomized, trial to evaluate the efficacy of adding crenolanib to salvage chemotherapy versus salvage chemotherapy alone in subjects with relapsed/refractory FLT3-mutant AML. Approximately 320 subjects will be randomized 1:1 to receive either salvage chemotherapy (HAM or FLAG-Ida) with crenolanib (treatment arm 1) or salvage chemotherapy (HAM or FLAG-Ida) alone (treatment arm 2).
Obesity and its related metabolic disorders are increasingly a heavy health burden to many parts of the world. Weight control is a well-known important step in avoiding type 2 diabetes mellitus (T2DM). It is also an essential component for normalizing the blood glucose and preventing macrovascular and microvascular insults to patients with diagnosed T2DM. However, life-style modification, physical exercise and dietary adjustment are ineffective measures which are unlikely to confer adequate and sustainable weight loss for the truly obese. On the other hand, large scale long-term follow-up studies have confirmed the role of bariatric surgery in providing durable weight loss and remarkable improvement on medical comorbidities. Among all the bariatric operations, laparoscopic sleeve gastrectomy (LSG) is currently the most widely adopted procedure worldwide because of its simplicity and effectiveness in weight reduction. However, LSG is not without risk. Staple-line hemorrhage, leakage and stenosis are potentially life-threatening complications. LSG is also costly because of the need for expensive laparoscopic staplers.
The most frequent reason for failure of laminate veneers made of glass ceramics (feldspathic, leucite based and lithium silicate based ceramics) was fracture of the ceramic, Therefore, ceramic materials that have higher fracture resistance, especially for patients suffering from abnormal occlusion, are needed.
Wide-awake hand surgery with local anesthetic, no tourniquet and no sedation (WALANT) is increasingly utilized. Conventional anesthesia for hand surgery involves a patient with a block, unable to perform motor function in the arm, and with patient either intubated or sedated, unable to follow surgeon instructions intra-operatively. Flexor tendon repair with a wide awake and cooperative patient is routinely performed successfully at some centres. This method provides several potential benefits including being able to have the patient actively flex the digit and visualize the repair site to assess for any tendon gapping at the repair site, ensure adequate approximation, gliding and absence of triggering. There have not been any prospectively collected randomized controlled trials comparing wide awake vs. regional/general anesthesia in flexor tendon repair. The purpose of our study is to assess for differences in early outcomes including stiffness, patient satisfaction and early complications in wide-awake anesthesia when compared to general/regional anesthesia for flexor tendon repair in zones I and II. Our hypothesis is that there is a lower complication rate and better outcomes when using wide-awake flexor tendon repair.
This study will be observational study. The goal of this study is to evaluate the quality of mandible and to assess the correlation between the jaw bone quality in a sample of Egyptian patients with chronic renal failure and duration of dialysis using CBCT.
Wear is the main reason for revision operations after joint arthroplasty. While the survival of modern implants is often longer than the expected life span in old patients, young patients (<60 years) have to expect at least one wear induced revision operation. The reason is the throughout all registries consistantly significantly reduced implant survival rates in young patients. In the swedish arthrplasty registry the 15 year survival for patients older than 75 years is 95 % and for those younger than 50 years is 75 %. This corresponds to a 5fold increased revision rate (5 % vs. 25 %) 15 years after implantation. This significant difference cannot be explained by the higher activity of younger patients alone. Patient specific factors, that modulate the biological reaction on wear particles, are therefore highly probable. These could explain the significant age dependency of implant survival. The main hypothesis of this study is therefore, that the biological reaction on wear particles depends on the patients age.
This study evaluates the clinical efficacy of the famous prescription in the treatment of unstable angina pectoris. All of the patients will be divided into 4 arms according to their syndrome type. One of the arms will be treated by conventional western medicine, the other three will be treated by different Chinese herbal medicine prescription at the base of conventional western medicine.
This is a randomized double-blind placebo controlled trial aim to compare the efficiency of genuine regional and non-genuine regional Rhizoma Atractylodis in treating functional dyspepsia. This study will also observe the clinical safety of genuine regional Rhizoma Atractylodis.The trial will be conducted in Xiyuan Hospital of China Academy of Chinese Medicine Sciences and Dongzhimen Hospital of Beijing University of Chinese Medicine.
