There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a multi-center, randomized, study to compare Iodine I 131 Tositumomab therapeutic regimen to Ibritumomab Tiuxetan therapeutic regimen in the treatment of patients with relapsed or transformed follicular non-Hodgkin's B-cell lymphoma. A total of 350 patients, approximately 175 patients per arm, will be enrolled at 30 to 40 sites in the United States.
Small contract VA Community Based Outpatient Clinics present unique challenges to implementation of collaborative care because of their distinct organizational characteristics and lack of on-site psychiatrists. A recent effectiveness study, successfully used telemedicine technologies to adapt the collaborative care model for small rural VA Community Based Outpatient Clinics. The purpose of the proposed study is to implement this telemedicine-based collaborative care model in small Contract VA Community Based Outpatient Clinics and determine its sustainability and cost-effectiveness.
The purpose of this study is to determine whether propranolol is better than oxytocin for the treatment of labor abnormalities. The endpoint is the rate of vaginal delivery experienced by women receiving prolonged oxytocin versus propranolol.
Pilot study of early versus delayed carotid endarterectomy (CEA) for small to medium-sized ischemic stroke caused by high-grade carotid stenosis.
Joint spaces are aseptic areas, meaning that they do not contain microorganisms. Any injury to the joint space could cause the entry of microorganisms, with the potential to cause infection. Septic arthritis refers to the infection of a joint space with microorganisms, usually bacteria. This invasion initiates a process of inflammation and causes irreversible damage to a joint cavity. Patients typically present with pain, swelling, decreased motion, and inability to use the joint. When bacteria enter a joint space, the host immune system responds by concentrating inflammatory cells within the joint. While inflammatory cells serve to eliminate the bacteria, they also produce substances that not only attack bacteria but also could destroy the joint space. These substances are called enzymes, and they could damage the cartilage (translucent fairly elastic tissue around the joint) and adjacent bone in the process. Because cartilage has a poor ability to cure itself, this process may lead to irreversible damage and chronic joint dysfunction. Studies have found that signs of early joint damage can be found within hours following joint infection. This is true even if antibiotic therapy (medicine to fight the infection) is started within 24 hours of infection. Also, delay in treatment has been related to poor outcome. However, the best method of treating septic arthritis has yet to be determined. Currently, there are two accepted ways for treating septic arthritis: serial needle aspiration (introducing a needle in the joint to aspirate the inflammatory liquid), and surgical lavage (opening and cleaning the joint space in the OR under anesthesia). Antibiotics are also used with these two forms of treatment. Supporters of surgery believe that the most dependable method of eliminating bacteria from a joint space is through arthrotomy (opening the joint with a surgical incision) and lavage (irrigation of the joint with copious saline solution) .Promoters of serial needle aspiration support this method because it is quick, does not require opening the joint space, and can be performed without anesthesia.At present, there are no conclusive studies comparing the two techniques. Hopefully, this study will help delineate the best course of management.
People with Fabry disease have an alteration in their genetic material (DNA) which causes a deficiency of the a-galactosidase A enzyme. Fabrazyme is a drug that helps to breakdown and remove certain types of fatty substances called "glycolipids." These glycolipids are normally present within the body in most cells. In Fabry disease, glycolipids build up in various tissues such as the liver, kidney, skin, and blood vessels because a-galactosidase A is not present, or is present in small quantities. The build up of glycolipid (globotriaosylceramide or GL-3) levels in these tissues in particular is thought to cause the clinical symptoms that are common to Fabry disease. This study is designed to verify that no loss of Fabrazyme occurs during simultaneous Fabrazyme infusion and hemodialysis in patients currently receiving Fabrazyme at a dose of 1.0 mg/kg every 2 weeks.
The purpose of this study is to evaluate whether high-resolution magnetic resonance imaging of the axilla with spectroscopy can identify nodal features suggestive of metastatic involvement in patients diagnosed with invasive breast cancer. This may enable us to define a select group of patients for whom axillary lymph node dissection could be avoided.
The purpose of this study is to investigate the efficacy of Raptiva (efalizumab) in the treatment of discoid lupus erythematosus (DLE). Discoid lupus erythematosus is a chronic disorder, which may lead to permanent and progressive loss of hair. Lupus is a condition of chronic inflammation cause by an autoimmune disease. Autoimmune diseases are illnesses which occur when the body's tissues are attacked by its own immune system. The immune system is a complex system within the body that is designed to fight infectious agents, for example, bacteria, and other foreign invaders. One of the mechanisms that the immune system uses to fight infections is the production of antibodies. Patients with lupus produce abnormal antibodies in their blood that target tissues within their own body rather than foreign infectious agents. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus erythematosus (DLE). Raptiva (efalizumab) is a humanized immunoglobulin(a protein extract from blood which fights off infection-sometimes called "antibody"), which targets the immune cells that are activated in inflammation. Raptiva has been approved for use in the management of psoriasis at doses of 1mg/kg, but is not approved for the treatment of DLE.
This study is designed to exam the effects of early management with high frequency percussive ventilation (HFPV) on patients with lung injury. Patients at risk for Acute Respiratory Distress Syndrome (ARDS) will be enrolled and randomized to one of two groups. One group will be managed with HFPV. The second group will be managed with conventional ventilation utilizing lung protective techniques. The primary endpoint of the study is rate of ventilator associated pneumonia. We hypothesized that use of HFPV in patients at risk for the development of ARDS will decrease the rate of ventilator associated pneumonia when compared to patients managed with conventional ventilation.
Primary: To determine the effectiveness of the rectal trumpet compared to the standard care in maintaining skin integrity in patients with fecal incontinence. Hypothesis (H1): There will be no difference in the failure rates of rectal area skin integrity between subjects receiving the rectal trumpet and those receiving treatment as usual (staqndard care). Secondary: To determine the ease of use, cost-effectiveness, and level of patient comfort with the rectal trumpet compared to the standard care in patients with fecal incontinence. Secondary (exploratory) hypotheses: There will be differences in the ease of use of the devices, costs of the devices, and patient comfort relative to the devices.
