Filter by: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.
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.
The purpose of this study includes the investigation of Metal-ion release and Renal Function analysis in M2a Total Hip Arthroplasty.
There is a lack of evidence of the long-term successful outcomes of antimicrobial endodontic treatment for primary teeth. This study intended to evaluate (by survival analysis) the effectiveness of an antimicrobial pulpotomy (chloramphenicol, tetracycline, zinc oxide/eugenol) in primary molars compared to calcium hydroxide pulpectomy, testing the hypothesis that antimicrobial pulpotomy could be an alternative pulp therapy for primary teeth with pulp inflammation or necrosis.

The purpose of this study is to test the effect of zoledronic acid over 2 years in preventing early collapse and progression of joint dome depression (≥ 2 mm by X-ray) of the femoral head in patients with large (> 30%: criteria according to Kim et al) nontraumatic osteonecrosis.
The purpose of the investigators study is to characterize the composition of the hard and soft tissues present in root canals of teeth previously diagnosed with necrotic pulps and incomplete root formation and treated with a triple antibiotic regeneration protocol. The investigators hypothesis is that treatment of teeth with necrotic pulps and immature apices with triple antibiotic paste will stimulate continued root formation by the deposition of dentin at the root apices. The primary outcome measure will be histological identification of mineralized tissue and adherent cells in the apical third of these teeth.
The purpose of this study is to monitor the performance of artificial hip joints implanted with two different bone cements, SmartSet® HV and SmartSet® GHV, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to SmartSet® HV or SmartSet® GHV and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments
The purpose of the study is to assess the long-term performance of the NexGen LPS-Flex Mobile Bearing Knee in the treatment of patients with severe knee pain or degenerative knee disease.
