Filter by:Background: For people who have Niemann-Pick disease, type C1 (NPC1), cholesterol and other fats have trouble moving out of liver and other tissue cells. This makes the cells sick. Researchers want to find out if a drug called VTS-270 can help. Objective: To test if VTS-270 is safe and effective in treating chronic liver disease associated with NPC1. Eligibility: People ages 3-60 with NPC1 Design: Participants may be screened by phone or under another protocol. Participants will have visits once a month for 12 months. If they have intrathecal injections, the study may last 15 months or more. The first visit will last about 5 days. Others will last 2-3 days. Participants will get VTS-270 injected into a vein at each visit. They can also choose to have intrathecal injections. These are like spinal taps. Some visits will also include: Physical exam Urine tests Blood tests. A small tube or needle will be inserted into the participants vein to collect blood. The small tube will also be used to give the VTS-270. Hearing tests: For one test, participants will have electrodes taped to their head. These will record brain waves. Breathing tests Ultrasound of abdomen: Sounds waves will take pictures of the participant s body. Chest x-ray: This is a picture of the lungs.
Peripheral nerve diseases can separately affect different kind of nerve fibres. Globally two kinds of fibres can be distinguished: large size and small size. The usual electromyogram only investigates large size fibres. Techniques to explore small size fibre function exist but are not used in common practice because of their very specialized aspect or their lack of diagnostic value. The purpose of this study is to develop a measurement technique of small size type C nerve fibre conduction velocity, to show that this velocity is reduced in patients suffering from polyneuropathies and to establish reference values in healthy patients.
Phase II of this study includes a pragmatic clinical trial which will take place at Northwest Rehabilitation Associates (NWRA) in Salem, OR to verify the efficacy of the system in a physical therapy clinic.
The purpose of this study is to evaluate the efficacy and safety of spinal cord stimulation (SCS) using the PINS spinal cord stimulator device for chronic and intractable pain.
This study aims to assess the feasibility of running a brief psychoeducation group intervention in an outpatient setting to assess the practicalities and benefits of offering this type of intervention for both clinicians and patients
This study plans to learn about how to measure symptoms (like tiredness or rash) in children with special healthcare needs who take 5 or more medications. Sometimes symptoms change in severity over time or new symptoms develop. This can happen after a new medication is started. This can also happen after the dose of an existing medication is changed. The Investigators believe that parents will be able to provide the best assessment of any symptoms that their child might be experiencing. This study asks parents to report any symptoms their child is currently experiencing.
In patients undergoing spine surgery, spinal nerve roots and spinal cord are vulnerable to surgical insults especially for instrumentation and may lead to long term sequelae. The incidence of clinical peripheral neuropathy after cervical spine surgery has been reported up to 30%. Intraoperatively, spinal cord and nerves function can be monitored using electromyography (EMG) and somatosensory evoked potentials (SSEP) and thereby, intervention can be made to potentially reduce the incidence of adverse neurological sequelae. However, conventional EMG and SSEP monitoring requires presence of a trained EP technician, use of needle electrodes and currently bulky EP equipment and is thus not practical for routine clinical usage. In this study, the invesitgators will assess the clinical feasibility of using a novel miniaturized and automated EMG/SSEP device (EPAD® 2.0) in spine surgical patients.
SWITCH Study
We use Transcranial magnetic stimulation (TMS), combined with simultaneous registration of electroencephalograph (EEG),for examining human cortical functionality. TMS-EEG is a noninvasive brain stimulation method that allows to study human cortical function in vivo. EEG provides an opportunity to directly measure the cerebral response to TMS, measuring the cortical TMS Evoked potential (TEP). In this study we measure TEPs, in a wide variety of neurological conditions and healthy as a measure of cerebral reactivity across wide areas of neocortex.
The purpose of this study is to investigate whether aerobic exercise improves the participant's ability to recover function in the arm and leg affected by the participant's stroke. The investigators are also calculating the cost effectiveness of the rehabilitation interventions.
