This randomized phase III trial is studying how well combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia that is likely to come back or spread. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) and giving the drugs in different doses and in different combinations may kill more cancer cells.
This pilot trial studies the differentiation of bone sarcomas and osteomyelitis with ferumoxytol-enhanced magnetic resonance imaging (MRI). Imaging procedures that allow doctors to more accurately differentiate between malignant bone sarcomas and osteomyelitis may help in diagnosing patients correctly and may result in more timely treatment.
This is a prospective, multi-center, non-randomized, non-controlled study designed to obtain survival and outcome data on the Continuum Metal on Polyethylene Acetabular System when used in primary total hip arthroplasty.
Tako Tsubo syndrome (TTS) is characterized by the occurrence in the context of mental or physical stress, a clinical and ECG of acute myocardial infarction without significant coronary artery stenosis, accompanied by a disorder Acute, reversible left ventricular who takes on a characteristic apical ballonnisation evoking the image of a Japanese octopus trap called Tako (octopus) tsubo (jar). Pathophysiology of unknown changes immediate life-threatening prognosis is often good in the longer term.
An increase in cardiac biomarkers has been shown to occur in 5% to 30% of patients after otherwise successful percutaneous coronary interventions (PCIs)(1) Apart from side-branch occlusion, intimal dissection and coronary spasm, a possible aetiology of myonecrosis after PCI might be distal embolization of atherogenic materials from plaque disruption,(2 )causing obstruction of blood flow at capillary level resulting in micro-infarction.(3,4 )Recent studies have suggested that pretreatment with Atorvastatin may be associated with a reduction in infarct size after elective PCI. (5-7 ). Actually the standard pretreatment in patients undergoing elective coronary-PCI and already treated with aspirin is clopidogrel loading dose administration before procedure.(8,9)The investigators compared a high (80mg) re-loading dose of Atorvastatin with a high loading dose of Rosuvastatin (40 mg) both administered within 24h before the procedure in reducing the rate of periprocedural MI. Therefore, the investigators will conduct a single center, prospective randomized study to assess whether a single, high (80mg) loading (within 24h)dose of Atorvastatin compared with a single loading dose of Rosuvastatin (20 mg) is effective in preventing elevation of biomarkers of MI after elective coronary stent implantation. We evaluate the incidence of MACCE(occurring of cardiac death, myocardial infarction (including periprocedural myonecrosis) and stroke at 30 days 6 and 12 month follow-up.
This study is being done to learn about the safety of the study drug bevacizumab(Avastin®), when used to treat radiation necrosis. The primary objective of this study is to test the feasibility of treating Central Nervous System (CNS) tumor patients suffering from radiation necrosis with bevacizumab every 2 weeks. The secondary objectives of this study are: - To evaluate improvement in neurologic symptoms associated with bevacizumab as assessed by clinical evaluation; - To investigate the neuro-imaging changes in radiation necrosis associated edema, including Mass Resonance (MR) spectroscopy; - To evaluate changes in corticosteroid use in patients with radiation necrosis following treatment with bevacizumab; - To evaluate changes in quality of life.
Few reports described outcomes of complete compared with infarct related artery (IRA) only revascularization in patients with ST elevation myocardial infarction (STEMI) and multivessel coronary disease (CAD). The purpose of this study is to determine outcome (death, myocardial infarction, target vessel failure) of 180 consecutive patients with STEMI and multivessel CAD undergoing primary angioplasty. Before the first angioplasty patients are randomized to 2 different strategies: 1) culprit vessel angioplasty only, 2) staged revascularization.
The purpose of this study is to monitor the performance of the DePuy PROXIMA™ hip 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.
This is a multicentre post-marketing prospective study to evaluate performance and clinical outcomes of AMIIStem primary hip system.
