Non-Arteritic Ischemic Optic Neuropathy (NAION) is a disease producing swelling of the optic nerve (the "cable" going from the eye to the brain) resulting in decreased vision. About 15% of patients will experience NAION in the second eye; many of these patients will be left legally blind. Currently, there is no treatment for NAION and for patients in whom the second eye becomes involved by the disease the outcome can be devastating. The investigators are conducting a study where the investigators will inject a medication into the involved eye of patients with NAION. This medication might decrease the swelling of the optic nerve and improve their vision in that eye.
The clinical and radiological data of patients with an acute ischemic stroke treated with intravenous thrombolysis (IVT) or intraarterial thrombolysis (IAT) in a Swiss stroke unit are assessed in a Swiss Multicenter Thrombolysis Registry. Like in clinical routine, a clinical evaluation takes place in a 3-months follow-up. Furthermore quality of life is assessed with a standardized questionnaire. The aim of the registry is to compare the safety and efficacy of IVT and IAT in patients with acute ischemic stroke. The registry also helps to improve in-hospital-management of stroke patients.
The primary study objective is to assess the feasibility of using the MindFrame System to safely and effectively restore blood flow in a thrombotic neurovascular occlusion in patients experiencing an ischemic stroke.
Transcorneal stimulation may enable neurons to survive degeneration processes via enhanced secretion of neurotrophic substances and direct stimulation of neurons.
The purpose of this study is to determine the safety, tolerability, and to explore the possible benefit of extended-release niacin (Niaspan®) in attempting to improve the recovery of patients after ischemic stroke.
Previously, the preconditioning signaling pathways have been studied on molecular level or in animal model. By using MR spectroscopy and imaging in a dynamic human model of preconditioning, we will have a better understanding how mitochondrial and endothelial function are affected by preconditioning in-vivo.
The present investigation will be a Phase II, single center, placebo-controlled, randomized, dose escalation, infusion modality (intracoronary vs transendocardial injection using the Cordis Biosense NOGASTAR TM Mapping Catheter with the Biosense MYOSTAR TM left ventricular injection catheter) transplantation of an autologous (your own stem cells) combination of bone marrow-derived stem cells into myocardium for the treatment of severe coronary ischemia. The purpose of this research study is to determine if the infusion of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in patients with symptomatic severe coronary ischemia(CI). In this trial we will determine whether the combination stem cell treatment is safe, feasible and results in the development of mature stable and/or collateral vessels and improvement of cardiac function. Coronary Ischemia (CI) is intractable angina due to severe coronary artery disease which can seriously decrease blood flow to the heart. CI needs a comprehensive treatment since the condition will not improve on its own. The overall goal of the treatment is to increase blood flow to the heart and improve symptoms of angina. The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriate blood supply to the heart. Patients eligible to participate in this study are those suffering from severe blockages of the vessels of the heart and are not candidates for percutaneous revascularization or surgical procedures.
Heart attacks are usually caused by a blood clot blocking an artery supplying blood to the heart. Current treatments are designed at relieving this blockage as quickly as possible to minimise damage to the heart muscle. However in restoring the supply of blood local damage known as "ischaemia-reperfusion injury" may occur. The aim of this study is to assess how clot forming and clot dissolving pathways are affected during this process, and examine the role of a natural inflammatory hormone, bradykinin. This will help us to understand the mechanism by which ischaemia-reperfusion injury may occur and to devise new treatments for heart attacks.
