NCT00030940
This study will explore the role of various immune factors involved in producing the disease symptoms in stiff-person syndrome (SPS) and follow disease progression in patients. SPS is a progressive disease in which unexpected noises, touches or stressful events set off muscle spasms and stiffness. It is thought to be an autoimmune disease in which the body produces antibodies that attack certain healthy tissues. A better understanding of the disease may help researchers design new therapies. Patients of any age with SPS may be eligible for this study, except those who: * Lack of serum anti-GAD antibodies * Have very advanced disease that precludes traveling * Have severe cardiovascular, renal, or other end-organ-disease states Candidates will be screened with a medical history and physical and neurological examinations to confirm the diagnosis of SPS. After screening, those enrolled in the study will be followed at the NIH Clinical Center every 6 months for 2 years (months 6, 12, 18, and 24) to have the following tests and procedures: * Physical and neurological examinations and review of symptoms (every visit) * Blood draw for routine tests and for research studies (every visit) * Stiffness assessment (every visit) - Patients are asked a series of questions about their stiffness, which physicians rate according to the number of stiff areas (e.g., 0-no stiff areas; 1-stiffness of the lower trunk; 2-stiffness of the upper trunk, etc.). * Lymphapheresis (at the beginning of the study and at 12 months) - This is a procedure for collecting large quantities of white blood cells. A needle is placed in a vein in the arm. Blood flows from the vein through a plastic tube (catheter) into a machine that spins the blood, separating it into its components. The white blood cells (lymphocytes) are removed, and the rest of the blood-plasma, red cells and platelets-is returned to the body through a second needle placed in the other arm. * Electrophysiologic studies - These studies include electromyography and nerve conduction testing. For electromyography, a small needle is inserted into a few muscles and the patient is asked to relax or to contract the muscles. The electrical activity of the muscle cells is recorded and analyzed by a computer. For nerve conduction testing, nerves are stimulated through small wire electrodes attached to the skin, and the response is recorded and analyzed. * Lumbar puncture (at the beginning of the study and at 12 months) - This procedure is done to examine the cerebrospinal fluid (CSF), which bathes the brain and spinal cord. After a local anesthetic is administered, a needle is inserted in the space between the bones in the lower back where the CSF circulates below the spinal cord. About 2 tablespoons of fluid is collected through the needle.
NCT00710593
The purpose of this study is to evaluate the immunogenicity, safety, tolerability, and behavioral impact of an HPV-6, -11, -16, -18 vaccine in HIV-infected young women.
NCT00001343
Turners Syndrome is a genetic condition in females that is a result of abnormal chromosomes. Patients with Turner syndrome are typically short, have abnormal physical features, and lack the physical changes normally associated with puberty. In addition, some patients with Turner syndrome have low bone density (osteoporosis) and differences in learning abilities. This study will research the effects of steroid hormones on patients with Turner syndrome. It will look closely at how taking steroid hormones effects the patient's rate of growth as well as the patient's ability to learn. In addition the study will investigate how different hormones (androgen and estrogen) work when given together as a combination. All patients asked to participate in this study will receive growth hormone injections. However, half of the patients will receive an additional sex steroid hormone (oxandrolone) in the form of a pill. The other half of the patients will receive a placebo or "sugar pill". This will allow the researchers to determine if the combination of the hormones produces different results than growth hormone alone. The study will last approximately 2 years. After 2 years of research the patients may qualify for an additional 2 years of treatment. Patients may benefit directly from this research with increased growth and improved ability to learn.
NCT00085410
This phase II trial is studying how well bortezomib works as first-line systemic therapy in treating patients with unresectable locally advanced or metastatic adenocarcinoma (cancer) of the bile duct or gallbladder. Bortezomib may stop the growth of tumor cells by blocking the enzymes necessary for their growth.
NCT00367796
This study will try to find the gene changes responsible for the birth defects in craniosynostosis, Philadelphia type. Craniosynostosis syndromes are a group of conditions that result from closure of one or more of the fibrous joints between the bones of the skull before brain growth is complete. Because of the premature closure, the brain is not able to grow in its natural shape; instead, it compensates with growth in areas of the skull where the joints have not yet closed. The defects in raniosynostosis, Philadelphia type, include skull malformations and webbing of the fingers and toes. Gene changes known to be involved in other craniosynostosis syndromes have not been found in the Philadelphia type syndrome. Therefore, finding the genetic basis of this disorder will provide important new information regarding craniofacial and limb development. This study includes members of a single large family affected with craniosynostosis, Philadelphia type. Participants have 1 to 2 teaspoons of blood drawn for genetic studies. A second blood sample may be requested for further research. Some blood may be used to establish a cell line for later studies. This involves growing the white blood cells from the blood sample. The cells can be kept in the laboratory to make more DNA or can be frozen for later use in craniosynostosis studies. Patients may also have their medical records reviewed.

NCT02433834
A Randomized, Double-Blind, Chronic Dosing (14 days), 5-Period, 7-Treatment, Placebo-Controlled, Incomplete Block, Cross-Over, Multi-center, Dose-ranging Study to Assess the Efficacy and Safety of Glycopyrronium MDI (PT001) Relative to Placebo MDI and Open-Label Serevent Diskus in Adult Subjects With Intermittent Asthma or Mild to Moderate Persistent Asthma
NCT01026493
RATIONALE: Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide. work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving veliparib together with temozolomide may kill more tumor cells. PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of giving veliparib together with temozolomide and to see how well it works in treating patients with recurrent glioblastoma.
NCT00981903
In this study the investigators will determine the safety and effectiveness of Tinzaparin in preventing blood clots for up to 12 months of treatment.
NCT00044239
The purpose of this study is to learn more about Obsessive-compulsive Disorder (OCD) in children. OCD usually has a slow onset, and symptoms that may remain at a stable level over time. A subset of children with OCD has a sudden onset and symptoms that fluctuate in severity over time. This study will also compare healthy children to those with OCD. This is an observational study; children who participate will not receive any new or experimental therapies. OCD affects nearly 1% of the pediatric population. The symptoms of this illness can interrupt development, causing significant psychological distress and producing life-long impairments in social, academic, and occupational functioning. A subgroup of pediatric OCD has been designated by the acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections). This type of OCD is characterized by sudden symptom onset and a relapsing-remitting course of illness; exacerbation of symptoms occurs with scarlet fever or strep. throat infections. This study will identify factors that distinguish children with PANDAS OCD from children with non-PANDAS OCD, and will compare both groups to healthy children. Children with OCD and their parents are screened with interviews and a review of the child's medical records. Participants have an initial evaluation that includes a psychiatric, physical and neuromotor exam, neuropsychological testing, psychological interviews, and a blood test. Structural magnetic resonance imaging (MRS) scans of the brain are also obtained. The MRS scan does not use radiation. After the initial evaluation, children with OCD have follow-up visits every 6 weeks for 12 to 24 months. They are seen yearly for 8 years after the study. If they have a significant improvement or worsening of their symptoms, they are asked to make a maximum of two extra visits. Parents of OCD patients are called four times a year to discuss any changes in the child's condition between yearly visits. All participants have a 1-year follow-up visit upon study completion.
NCT00072813
This study will examine the possible structural and functional abnormalities in patients with an inherited form of epilepsy. It will use magnetic resonance imaging (MRI). Uncontrolled epilepsy is a serious neurological problem with major harmful medical, social, and psychological effects, as well as greater mortality compared with the general population. The cost per year in the United States is at least $12.5 billion. There have been advances in diagnosing the disease, but the cause cannot be determined in many cases. Recently, several seizure syndromes found in families have been described. One syndrome of particular interest involves the lateral temporal lobe of the brain and often includes auditory features. Patients with that kind of syndrome may hear monotonous unformed sounds, but sometimes they may hear complex sounds, such as a song. Patients are eligible for this study if they have a specific form of familial epilepsy that is being studied at Columbia University in New York. Family members without seizures are eligible as well. All the patients in the study will be evaluated at Columbia before participating. Healthy volunteers aged 18 to 55 also may be eligible for this study. Participants will undergo a medical history and physical examination. During the study, they may have three or four sessions of MRI. During the MRI, patients will lie still on a table that can slide in and out of a metal cylinder surrounded by a strong magnetic field. Scanning time varies from 20 minutes to 3 hours, with most scans lasting between 45 and 90 minutes. Patients may be asked to lie still for up to 60 minutes at a time. As the scanner takes pictures, there will be loud knocking noises, and the patients will wear earplugs to muffle the sound. Patients will be able to communicate with the MRI staff at all times during the scan and may ask to be moved out of the machine at any time. Some scans may be done in a 3 Tesla scanner. It is the latest advance in MRI, with a stronger magnetic field than in the more common 1.5 Tesla scanner. Functional MRI (fMRI) is done while patients are performing tasks, such as moving a limb or speaking. Patients will have an opportunity to practice such tasks before entering the scanner. The fMRI will take about 1 hour. ...
NCT00097682
This study will explore what research patients understand about financial collaborations in the research setting and their concerns about these collaborations. Financial partnerships are crucial to advancing medical research; however, they are giving rise to increasing concerns about financial conflicts of interest and possible impacts on the integrity of research and patient safety. This study will examine patients' views about financial ties between drug companies and the doctors running research studies, as well as ties between the drug companies and the cancer centers where the studies are conducted. Patients 18 years of age and older who are enrolled in cancer studies at the National Cancer Institute in Bethesda, MD; the Fred Hutchinson Cancer Research Center in Seattle, WA; the Dana-Farber Cancer Institute in Boston, MA; the Columbia Comprehensive University Herbert Irving Cancer Center in New York, NY; and the University of Colorado Cancer Center in Denver, CO, may be eligible for this study. Participants are interviewed about the following: * Patients' awareness and understanding about individual and institutional financial conflicts of interest, and how such conflicts, if they exist, are being managed * The impact of a researcher's financial ties on the patient's decision to participate in that researcher's study * The impact of the institution's financial ties on the patient's decision to participate in research at that institution * Attitudes about policies and practices regarding conflicts of interest in the research setting * Attitudes about disclosure of conflicts of interest in the research setting * Patient symptoms and performance * Patient's cancer trial * Patient's cancer history * Patient's trust * Patient demographics (gender, age, race, religion, education, income, health insurance, employment).
NCT01522235
The purpose of the study is to see if administering intravenous immune globulin (IVIG) (putting immune globulin directly into your blood) helps to improve the symptoms of orthostatic hypotension (sudden fall in blood pressure when a person stands up) and quality of life in men and women who have autoimmune autonomic ganglionopathy (AAG).
NCT00918047
Study to evaluate the pharmacokinetics, safety, and tolerability of OXC XR as adjunctive therapy in pediatric subjects with refractory partial epilepsy.
NCT00048880
Background: * Some cancers, such as Hodgkin's disease, anaplastic large cell lymphoma and others, have a protein on the surface of the cancer cell called CD30. * HeFi-1 is an antibody that binds to the CD30 protein and sends signals to the cancer cells that can cause them to die. Objectives: * To determine the highest dose of HeFi-1 that can safely be given to patients with tumors that have the CD30 protein. * To determine the response of the tumor to treatment with HeFi-1. Eligibility: * Patients 18 years of age and older with Hodgkin's disease, anaplastic large cell lymphoma, cutaneous T cell lymphoma and adult T cell leukemia or lymphoma who have signs of tumor growth or recurrence following standard treatment * Patients' tumor cells must have the CD30 protein. Design: * Groups of three patients are treated with increasingly higher doses of HeFi-1 (ranging from 0.5 to 5 mg/kg) to determine the highest safe dose. * HeFi-1 is infused through a vein on 4 days, followed by 2 days of rest over a 10-day period. Patients may receive up to 2 treatment courses if they show some response and do not have severe side effects. * Blood samples are collected several times during the study to determine safety. A lymph node biopsy is done at the beginning of the study to test the effect of HeFi-1 on cancer cells in the test tube, and a bone marrow biopsy may be done at the end of treatment if the bone marrow was positive for tumor cells at the beginning of treatment.
NCT00069693
This study will conduct tests with patients with primary chronic orthostatic intolerance (COI) to learn more about this disorder of the autonomic nervous system. Healthy normal volunteers and patients 18 years of age and older with COI may be eligible for this study. Participants undergo one or more of the following tests and procedures: * Blood studies, including arterial catheter insertion to measure blood pressure and collect arterial blood samples, blood flow studies using sensors applied to the skin and a pressure cuff around a limb, blood volume studies using injection of radioactively labeled human serum albumin and gene studies to look for genetic abnormalities associated with certain proteins. * Imaging studies, including CT scan of the adrenal glands, heart ultrasound, and PET scanning. * Electrocardiogram * Microdialysis to measures levels of chemicals in the body fluid of certain tissues. A thin tube is inserted into the skin and a solution is passed through it. Chemicals in the body tissues enter the solution in the tube. The solution is collected and the chemical levels are measured. * Neck suction. Neck suction is applied to test a reflex the brain uses to regulate blood pressure. * Perometry. Limb volume is measured using an infrared light that moves up the limb. * Quantitative sudomotor axon reflex test to evaluate an aspect of autonomic nervous system function. A small amount of a brain chemical (acetylcholine) is applied to the skin with a tiny amount of electricity, and the sweat in a nearby patch of skin is measured. * Skin electrical conduction test using sensors on the skin to measure sweat production. * Skin and core temperature measurements using sensors on the skin and in the ear canal. * Tilt table test. The subject lies on a table, secured with straps around the chest and legs. Sensors are placed on the arms and chest to monitor blood pressure, pulse rate, and heart rhythm. A catheter is placed in a vein in each arm to collect blood samples and give drugs. Another catheter is placed in an artery to draw blood and monitor blood pressure. The subject is given an infusion of norepinephrine and epinephrine, and baseline measures and blood samples are taken. The table is tilted upright and more measurements and blood samples are taken at intervals for up to 30 minutes. The table is returned to a horizontal position and additional measurements and samples may be taken. Drugs may be administered during the tests, including acetylcholine, epinephrine, and norepinephrine, radioactive chemicals used in imaging studies, and drugs that affect blood vessels, heart rate, and force of heart contractions.

The target ratio between 6-8 years and 9-11 years age groups is approximately 1:1 in each treatment arm, with a minimum of 3 children per age group in each treatment arm.
NCT00339638
This study will identify chemical and protein markers in the blood of people who carry the human T-lymphotropic virus type I (HTLV-I), a virus associated with various pathologies, including an increased risk in adults of a rare and aggressive cancer called adult T cell leukemia/lymphoma (ATL). The study will also examine differences in these markers before and after the onset of ATL. ATL has been reported in every area where HTLV-1 is common, including the Caribbean and parts of Japan, West Africa, the Middle East, South America, and Pacific Melanesia. Risk factors for the disease are largely unknown and seem to vary among those affected in different endemic regions. People who acquire the infection early in life are thought to be at higher risk than those who are infected later. In Japan, men seem to be at greater risk than women, but the same is not evident among the black population in the Caribbean and Brazil. Findings from this study will increase understanding of the cause of ATL and identify differences in tumor characteristics and the course of disease across geographical areas. Study subjects are drawn from among participants in eight studies of HTLV-1 carriers, including the 1) Jamaica Mother-Infant Cohort Study, 2) Jamaica Family Study, 3) Jamaica Food Handlers Study, 4) Miyazaki Cohort Study in Japan, 5) Nagasaki Cohort Study in Japan, 6) Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Disease, 7) HTLV Outcome Studies in the United States, and 8) GIPH Cohort Study in Brazil. Stored blood samples previously collected from patients in the above studies who did and did not develop ATL will be analyzed for immunologic and genetic factors.
