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 study will prospectively compare the findings of two diagnostic tests, Direct Magnetic Resonance Arthrography(MRA) and Indirect MRA, to the findings during shoulder arthroscopy in patients with shoulder pain. The sensitivity and specificity of both Direct and Indirect MRA's in diagnosing specific pathologies of the shoulder will be determined using shoulder arthroscopy as the gold standard.
This research studies protein in tumor samples from patients with non-small cell lung cancer. Finding specific proteins in tumor tissue samples from patients with cancer may help doctors tell what type of lung cancer a patient has and plan better treatment.
Chronic hepatitis C is a major cause of liver disease and is thus an important public health problem. Although some strains (genotypes) of the hepatitis C virus are highly responsive to treatment with a combination of peginterferon and ribavirin, the most common form of the virus (genotype 1) is relatively resistant to this treatment. Recently, telaprevir has been approved by the Food and Drug Administration to be given in combination with peginterferon and ribavirin. This 3-drug combination boosts the remission rate for genotype 1 hepatitis C to that seen with other more responsive hepatitis C genotypes treated with only peginterferon and ribavirin. However, telaprevir has additional side affects such as rash and anemia that may limit its usefulness. Intriguingly, about one third of patients infected with genotype 1 hepatitis C, who have a specific variation (polymorphism) in the DNA sequence (CC) near an immune response gene (IL28B), in fact are highly responsive to 2-drug treatment with peginterferon and ribavirin. This raises the possibility that individuals who have the IL28B CC polymorphism may not need to be treated with the addition of telaprevir and could therefore be spared unnecessary side effects. Thus, the purpose of this study is to determine among genotype 1 hepatitis C patients with the IL28B CC polymorphism the success rate and side effects of 3-drug treatment compared with 2-drug treatment. In this study, patients with genotype 1 chronic hepatitis C who have the IL28B CC polymorphism will be randomly assigned to be treated with telaprevir, peginterferon, and ribavirin or with only peginterferon with ribavirin. These medications and the procedures involved, including patient history, physical examination, and obtaining small volume blood specimens (less than 4 teaspoons) for laboratory testing, are within the scope of standard management of hepatitis C treatment. All patients will be monitored during treatment with periodic blood testing (weeks 2, 4, and every 4 weeks thereafter while on treatment, and 24 weeks after stopping treatment) and office visits (weeks 5, 12, 25, 49 while on treatment and 25 weeks after stopping treatment). The success of treatment will be judged by the presence or absence of detectable virus in blood, as measured by a sensitive diagnostic test (PCR). The data to be generated will include measurement by PCR of hepatitis C viral loads before, during, and after treatment, as well as reporting of adverse drug effects.
Burned patients because of their increased oxidative stress have severely depleted vitamin E, which is a dietary antioxidant. Oxidative stress is responsible for much of the pathophysiology seen in burned patients, which leads to acute and chronic morbidity and mortality, in addition to a decrease in their quality of life. Oral vitamin E will be used to reverse the oxidative stress of burn injury and, in the process, decrease the secondary consequences of thermal trauma. This proposal will demonstrate the benefit of maintaining adequate vitamin E status.
Most resectable tumors arising in the body or tail of the pancreas are malignancies or premalignancies which are surgically treated with distal pancreatectomy in combination with splenectomy. Retrieval of the lymph node tissue which lies along the splenic vessels is necessary to complete an oncologically sound operation. Two techniques for spleen preserving distal pancreatectomy have been described, but only a small number of lesions are amenable to spleen preserving pancreas surgery because these operation compromise oncologic principles. Removal of a normal spleen usually does not cause immediate consequences but can make patients vulnerable to life threatening infections. Asplenic patients must be vigilant for these infections and antibiotic prophylaxis is recommended anytime a fever occurs. Splenectomy results in measurable changes in the cellular components of the blood. If thrombocytosis occurs as a result of splenectomy, it requires life-long antiplatelet treatment. Some childhood hematologic disorders such as hereditary spherocytosis are successfully treated with partial splenectomy. The post-surgical remnant spleen has been shown to be viable and functional. Both hematologic and immunologic function of the spleen seems to be preserved in most patients. Partial splenectomy has also been successful ly employed to treat benign and malignant lesions of the spleen. Unfortunately these indications for surgery are rare and so the experience with partial splenectomy is small. To date, distal pancreatectomy with partial splenectomy has not been described in the medical literature. The investigators have devised a surgical procedure combining distal pancreatectomy with partial splenectomy, in principal allowing preservation of splenic function without compromise of oncologic principles. This procedure is possible now because of new technology which allows for near bloodless transection of solid organs. These instruments are routinely used in liver, kidney and pancreas surgery. There are scattered reports of successful use of these instruments in splenic transection, but there is no large experience to date. The study intends to answer the question, is the proposed procedure, distal pancreatectomy and partial splenectomy, a viable alternative to the current standard of care, distal pancreatectomy with total splenectomy, for patients who will undergo surgical treatment of pancreas lesions arising in the body or tail of the pancreas?
The investigators will use different types of brain imaging (MRI) in patients with Phenylketonuria (PKU) who are currently not on a strict diet to test the hypothesis that there is improvement in brain circuitry and biochemistry after return to diet and/or sapropterin dihydrochloride (Kuvan).
The purpose of this study is to determine if the magnetic needle, in combination with magnetic nanoparticles can accurately identify minimal residual disease in leukemia patients.
The purpose of this study is to determine whether stereotactic body radiation therapy (SBRT) with simultaneous boost (higher radiation dose) to areas within the prostate with more prominent cancerous growth (intraprostatic lesions) utilizing intensity modulated radiotherapy (IMRT) planning techniques is a safe and effective treatment in patients with low- and intermediate-risk localized prostate cancer.
This study is to find out if 3.0 Tesla (3.0-T) Magnetic Resonance Imaging (MRI) will improve in diagnosing breast cancer in women with high-risk of breast cancer.
The study is designed to see if once daily oral dosing of LY2608204 will help control diabetes as measured by the glycosylated fraction of hemoglobin A (HbA1c) level. It will also help to determine the safety of the medication and the most useful doses of the medication.
