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.
Supracondylar fractures are the most common elbow fractures in children. In the current orthopedic literature crossed pinning and lateral-only entry techniques are co-gold standards of operative treatment. The crossed pinning technique has been shown to be biomechanically superior especially under torsional loading but has a higher incidence of iatrogenic injury to the ulnar nerve. All studies comparing these techniques to date have been either biomechanical or retrospective in nature. A randomized, controlled, prospective study comparing these two popular techniques has not been performed. The purpose of this study is to prospectively evaluate the amount of displacement incurred when treating type III supracondylar humerus fractures in children with crossed pinning versus lateral-entry only technique. Overall complication rate, loss of reduction, iatrogenic neurovascular injury, and pin tract infection rates between the two cohorts will be evaluated. The study population will comprise all patients less than ten years of age presenting to Scottish Rite Hospital during the study period with a type III supracondylar fracture managed by the Children's Healthcare of Atlanta Orthopedic Group. All patients will be randomized to one specific treatment arm based on surgeon preference established at the onset of the study. The hypothesis to be tested is that no difference in amount of displacement or overall complication rate is present between these two techniques. Radiographic parameters measured pre-operatively, immediately post-operatively and four weeks post-operatively will be quantitatively evaluated and compared. Chart reviews to determine complications during the treatment period will be made. Pre-study power analysis and post-study statistical analysis will be performed.
Nearly all patients with Duchenne's Muscular Dystrophy (DMD) have scoliosis. Posterior instrumented spinal fusion, which is a surgery to correct scoliosis, has been shown to improve quality of life and satisfaction of both parents and families. The progressive muscular weakness leads to the development of scoliosis soon after the child has become unable to walk. The muscular weakness and scoliosis also affect the pulmonary function of these children. Pulmonary Function Tests (PFT) have been used to determine "pulmonary fitness" prior to surgery as a way to determine how well or if the child will tolerate surgery. Children with poor results on the PFT are determined to be too fragile to tolerate such a large operation. The physicians conducting this study feel that the PFT may be inaccurate and that this may not be the best single test to determine "pulmonary fitness". The physicians conducting the study think things like the time of day the study is done, how tired you are when you complete the test, and how well you understand the test may affect the results of the test.
This clinical trial is being conducted to 1) evaluate the possible usefulness of a panel of cardiac markers in assessing emergency department patients with possible acute coronary syndrome, 2) evaluate the usefulness of BNP in assessing emergency department patients with possible acute coronary syndrome, 3) determine if BNP can be used to predict adverse events during hospitalization and in the emergency department, and 4) evaluate how a Point-of-Care testing platform affects resource utilization in the emergency department.
The purpose of this study is to determine if Divalproex Sodium can be used to Treat and Prevent Depression in Patients with Bipolar Disorder who have Comorbid Alcohol Dependence/Abuse.
Based on the limited amount of experience with plasmapheresis and CytoGam concomitant use, the researchers seek to evaluate the pharmacokinetics (drug absorption, distribution, and elimination) of this therapy. The researchers are also interested in evaluating the pharmacokinetics of the various immunosuppressant medications that patients will receive such as tacrolimus, mycophenolate mofetil and daclizumab.
The purpose of this study is to test the effectiveness of the amino acid arginine in reducing liver injury in individuals with alcohol-related hepatitis.
Hypothesis: The use of cascade platelet-rich fibrin matrix (PRFM) on medium and large sized rotator cuff tears will improve patient results versus the control results by 50%. The purpose of this study is to examine the effect of PRFM on rotator cuff repairs. Since locally applied platelet-derived growth factor (PDGF) has shown early promise in enhancing tendon and ligament healing in anterior cruciate ligament (ACL) and medial collateral ligament (MCL) reconstruction, the investigators believe that locally applied PRFM will enhance the quality of rotator cuff repairs.
This project is a clinical study of women with high blood pressure who become pregnant. Preeclampsia is a syndrome developing at the end of a pregnancy characterized by an abrupt rise in blood pressure (BP), blood clotting and kidney dysfunction, and may result in premature delivery, infant death, and maternal bleeding, kidney failure and stroke. The goal is to determine whether lowering blood pressure to a normal pressure of 120/80 is associated with a lower incidence of preeclampsia. Women who are completely healthy have a 5% chance of developing preeclampsia, however women with preexisting high blood pressure have a 25% chance of this complication. Several studies, including our own suggest that higher blood pressure early in pregnancy (<20 weeks) is associated with an even higher risk of preeclampsia. Currently we, the researchers at Weill Medical College of Cornell University, do not know how to treat women with high blood pressure and/or kidney disease during pregnancy. Keeping the BP in the normal range may be beneficial to the mother. On the other hand, we are not sure if the blood pressure lowering or the medications may or may not have adverse effects for the baby. Different trials to answer this question have been performed with no clear conclusions. Because of these uncertainties, we propose to compare two different strategies for treating women with high BP who become pregnant. We will treat half the women with BP medications to normalize BP (120-130/80 mm Hg) (experimental group) and the other half with the goal of keeping the BP slightly higher (140-150/90-100 mm Hg)(standard therapy group). We will determine which approach results in healthier pregnancies, and lower incidence of preeclampsia. Reducing the incidence of preeclampsia would be of significant benefit to both mothers and babies.
The study will correlate the volumes of the brain obtained from magnetic resonance imaging (MRI) scans done at term gestation for infants born prematurely who weighed less than 1000 grams at birth with their corresponding development at 18 months corrected age.
Healthy African American subjects with normal hepatic and renal function will be administered 10mg adefovir dipivoxil in a fasting state. Subjects will have blood and urine collections over the following 24 hours for the measurement of adefovir renal clearance. To investigate the role of age in renal adefovir elimination, 8 subjects will be enrolled from each of the following age groups: 18-25 years and 48-55 years.
