Filter by:The objective of this study is to evaluate an antibiotic therapy called Rifalazil to determine its effect on hardening of the carotid arteries.
1. Primary objectives a. To evaluate the Effects of intravitreal Bevacizumab on polypoidal choroidal vasculopathy(PCV) 2. Secondary objectives 1. To assess the changes in visual acuity 2. To assess the change in lesion characteristics of PCV - size of PCV - fluorescein leakage - foveal thickness 3. To investigate the safety of intravitreal Bevacizumab in patients with PCV 4. To assess the effect of intravitreal Bevacizumab on the recurrence rate and the the incidence of submacular hemorrhage in patients with PCV
Implantation of bone marrow cells, including endothelial progenitor cells, into ischemic limbs has been shown to improve collateral vessel formation. In the present study the safety and feasibility of autologous blood mononuclear cells implantation will be investigated in patients with severe peripheral atherosclerosis.Twenty cases will be enrolled. Improvement in the ankle-brachial pressure index (ABI:>0.1), ischemic ulcers and angiography as well as laser doppler flow will be evaluated until six months.
The investigators want to evaluate the burden of peripheral artery occlusion disease in Taiwan peritoneal dialysis (PD) patients by using ankle-brachial pressure index (ABI) and toe-brachial pressure index (TBI). Furthermore, the investigators hope to demonstrate the possible casual factors of peripheral artery occlusion disease (PAOD) in PD patients.
The purpose of this study is to determine if bone marrow derived adult stem cells are safe and effective in inducing development of new blood vessels (angiogenesis) in the legs of patients with severe peripheral vascular disease.
This is the first clinical research trial in which intravenous Prostaglandin E1 (PGE1 is a vasoactive hormone) will be used as supportive treatment along with the angioplasty procedure to treat or open up a blocked artery within one lower limb or the most affected of two limbs in subjects with Peripheral Arterial Occlusive Disease.
The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies. Patients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland. The study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following: - Blood and urine tests not more than 2 tablespoons of blood will be drawn for various tests. - Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm. - Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain. - Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels. - Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck. - Echocardiogram-sound waves are used to image the heart and evaluate heart function. Patients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and/or 12 months, when some of these tests may be repeated to assess changes over time
