Background: - Many people who have cerebral palsy (CP) have spastic diplegia, which affects the legs and causes difficulty with leg movement and walking. Research has shown that exercise can help those with CP learn to move their arms better, but more research is needed to determine whether exercise programs can improve leg movements in people with CP. - Walking on a treadmill with the help of a physical therapist has improved the treatment outcomes of some individuals with spinal cord injuries. Many children with CP already have physical therapy but still have trouble with walking and leg coordination. Two other kinds of exercise machines, a stationary bicycle and an elliptical machine, used in the home, may be able to help children with CP walk better and move their legs better. Objectives: - To see how children with cerebral palsy (CP) move their legs differently from children without CP. - To see if an exercise program can improve leg coordination in children with CP. Eligibility: - Children between 5 and 17 years of age who either have spastic diplegia CP or are healthy volunteers. Design: - Children who are able and willing will have magnetic resonance imaging (MRI) scans at the start and the end of the study. - During Part I of the study, participants will demonstrate their leg and muscle function with the following tests: - Measurement of leg size and movement - Combined camera motion study and electrical impulse evaluation to assess how well the participant walks (with or without an assistive device, as needed) - Leg movement tests on an exercise bicycle and elliptical machine - Tests of leg muscle strength, stiffness, and effectiveness - Ultrasound scans of leg muscle - Parents of participants will complete computer-based questionnaires about their child s motor abilities. - A smaller group of participants will continue to Part II of the study, which involves regular exercise of 20 minutes a day, 5 days a week, for 3 months, on a stationary bicycle or elliptical trainer. Half of the group will start this exercise program immediately after the first part of the study, while the other half will wait 3 months before beginning the exercise program. - During Part II, participants will return to the clinical center for two more sets of the tests and evaluations performed in Part I.
The purpose of this study is: - To determine whether oral narcotic medication versus placebo improves the pain and anxiety scores for pediatric patients requiring laceration repair in the pediatric emergency department and receiving the standard of care with lidocaine treatment - To evaluate for a statistical difference in pain scores in children during laceration repair - To evaluate for a statistical difference in State-Trait Anxiety Inventory for Children (STAIC) scores during laceration repair
Background: - Autism spectrum disorders (ASDs) are a group of developmental disorders that affect communication, social interaction, and behavior. Relatively little is known about the relationship between genetics and behavior among these individuals and their close relatives. Researchers are interested in using interviews and rating scales to better understand these issues, as well as collecting brain scan data and genetic samples for testing and comparison. - By comparing test results and genetic samples from healthy volunteers, people with ASD, and parents (or caregivers or legal guardians) of the first two groups, researchers hope to better understand the neuroscience of ASD. Objectives: - To learn more about the brain in healthy people and in people with autism spectrum disorders. - To study genes that might be involved in autism spectrum disorders by collecting DNA samples from participants. Eligibility: The following groups of participants will be eligible for the study: - Individuals between 5 and 89 years of age who have autism spectrum disorders. - Healthy volunteers between 5 and 89 years of age. - Cognitively impaired children between 5 and 17 years of age. - Parents/caregivers/legal guardians of individuals in the above three groups. Design: - Participants will visit the National Institutes of Health Clinical Center for research tests, which will be administered over multiple visits. Researchers will determine the specific tests to be administered based on the medical history of the study participant. - Researchers will study the brain through interviews, tests of thinking and memory (neuropsychological tests), brain imaging with magnetic resonance imaging (MRI), and magnetoencephalography (MEG). - The study will also collect blood or saliva to obtain a DNA sample.
This proposal represents a unified programme supported by both clinical and academic staff in the Departments of Paediatrics at Imperial College and St Mary's Hospital, Southampton Hospital and John Radcliffe Hospital (Oxford). St Mary's Hospital is the hub of a paediatric network for West London, and forms part of the Paediatric Intensive Care Network for the London region, with potential access to a population of 3 million children. We aim to improve diagnosis and understanding of children with infectious, inflammatory and allergic conditions. Our study will establish well-characterised cohorts of patients with defined conditions, in whom microbiological and patient samples will be used to understand the contribution of genetic background, differential gene expression, proteomics and the pathogen type to the disease process. Unwell children coming to hospital through any route will be invited to join the study. Entering the study will entail the child having blood taken for research purposes in addition to the clinically indicated tests. We will also recruit well (control) children who are having blood tests performed for elective purposes, such as surgery. In addition, children presenting with an illness that is likely to have an infectious aetiology will also have samples collected for microbiological diagnosis. Those samples taken for ordinary diagnostic purposes (such as blood, urine, cerebrospinal fluid (CSF), bronchoalveolar lavage (BAL) fluid or nasal brushings for epithelial cell cultures) would also be used for state-of-the-art diagnostic techniques, in order to maximise the likelihood of confirming a microbiological diagnosis. Where healthy, uninfected children are having invasive procedures, such as lumbar punctures, we would aim to recruit these children as controls and collect biological samples such as CSF samples. This bid addresses the need for translational research in paediatrics, by building on the world-class basic science and clinical paediatric base at Imperial College and St Mary's Hospital.
Type 1 diabetes (T1D) is still associated with tremendous morbidity and premature mortality. Patients require multiple daily insulin injections throughout their lives as well as close monitoring of their diet and blood sugar levels to prevent complications. Unfortunately, there is presently no permanent cure for diabetes. Whole pancreas or islet cell transplantation is available only to a very limited number of patients and necessitates potential lifelong immunosuppressive therapy. Autologous stem cell transplants have been used successfully for ALL (acute lymphoblastic leukemia), AML (acute myeloblastic leukemia) and for the treatment of a variety of cancers including breast cancer and neuroblastomas, and more recently for the treatment of autoimmune disorders such as multiple sclerosis (MS), lupus-like disease, and rheumatic disorders. Recently it was shown that bone marrow-derived stems cells transplanted into diabetic mice led to reduced hyperglycemia within 7 days after transplantation and was sustained until they were sacrificed at 35 days post-transplantation. The investigators' goal is to transfuse autologous umbilical cord blood into 23 children (Germany 10 and 20 Controls) with T1D in an attempt to regenerate pancreatic islet insulin producing beta cells and improve blood glucose control. As secondary goals, the investigators aim to track the migration of transfused cord blood stem and study the potential changes in metabolism/immune function leading to islet regeneration.
Comparison of two regimens (Sevorane/LMA ctr. Propofol/Remifentanil) for children undergoing MRI in general anesthesia.
Physical activity is a well-known and powerful tool in medicine,having preventive, palliative, and curative properties. This has not been sufficiently examined in children in remission from cancer. In this study, children in remission from cancer will be divided into exercise and control groups. The interventional group will perform two supervised, 60-minute weekly exercise sessions. Outcome measures of the exercise intervention will be quality of life, mood, cardiorespiratory fitness, body composition and bone mineral density.
This is a children's study evaluating the effects of a tonsillectomy with tonsillar fossae closure compared to without closure of the operative wound.
The Study is designed to collect information about adverse events that occur in children undergoing anesthesia in participating hospitals. Demographic information will be collected on all anesthetics. An analysis of each adverse event will be performed and entered into the database. From this information we will devise strategies to prevent these adverse events.
