Dexmedetomidine and Propofol for Pediatric MRI Sedation
HeadacheTumor5 moreThe purpose of this study is to compare the results of combining two anesthetic medications (dexmedetomidine and propofol) in low doses with a standard dose of a single drug that is commonly used to provide sedation/anesthesia for MRI studies in young children (propofol). The drugs used for the MRI scan in this study will be chosen randomly. Half the patients will receive small doses of propofol and dexmedetomidine. The other half will receive propofol administered constantly throughout the scan. Other drugs that may be used include sevoflurane and nitrous oxide at the start of the sedation (for placing an intravenous), lidocaine (to reduce the pain of propofol injection) and glycopyrrolate (to prevent the heart rate from decreasing too low. The investigators will record 5 additional blood pressures and heart rates. If additional medications are required to complete the scan, the investigators will administer whatever is necessary. At the end of the study, the investigators will have an observer record the time it takes for participants to spontaneously open eyes , to be able to drink liquids and/or eat and to behave as before the study. Also, it is very important that the investigators find out from participants about changes in behavior, or if eating or sleeping habits were unusual following completion of the study. For that reason, the investigators will call participants in a day or so following the MRI scan. The investigators expect to recruit 40 children between the ages of 12 and 72 months for the study and hope to have the study completed in December 2018.
A Placebo-Controlled Effectiveness in INPH Shunting (PENS) Trial
Idiopathic Normal Pressure Hydrocephalus (INPH)The Placebo-Controlled Effectiveness in Idiopathic Normal Pressure Hydrocephalus (iNPH) Shunting (PENS) trial is a multi-center blinded, randomized, placebo-controlled design investigation of cerebrospinal fluid (CSF) shunt surgery to study the shunt effectiveness in iNPH patients.
Anterior Pituitary Function in Patients With Hydrocephalus
Normal Pressure HydrocephalusHydrocephalus (secondary or idiopathic) is a condition characterized by dilatation of the lateral and third ventricles, and often associated with increased intracranial pressure (ICP). We hypothesize that either the ventricle dilatation or the increased ICP may cause disturbances in the hypothalamic-pituitary axis, resulting in different degrees of hypopituitarism. The goal of this study is to determine the prevalence of hypopituitarism in adult patients with hydrocephalus.
Impact of a Standing Program in a Child With Spina Bifida: A Case Report
Spina Bifida With HydrocephalusThe purpose of this case study is to investigate a child with MMC who has significant knee and hip flexion contractures to answer the following research questions: 1) Is a home standing program effective in reducing hip and knee flexion contractures in a child with MMC? 2) Does a home standing program result in a change in the quality of functional movement? A Physical therapist, PT, will administer the Peds NRS and goniometric measurements prior to the start of the study and at the end of the study. The PT will also provide the parent instruction on the standing home program with weekly check-ins to ensure the parent and child are able to follow the home program. The home standing program will last 8 weeks. The parent will keep a written log of stander use. The Peds NRS scores and goniometric measurements will be compared pre and post intervention. The expected outcome is that the Peds NRS scores and hip and knee extension range of motion measurements will improve.
Positron Emission Tomography Imaging of Brain Amyloid in Normal Pressure Hydrocephalus
Normal Pressure HydrocephalusTo determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical and histochemistry estimates of amyloid levels in frontal lobe biopsy samples obtained from subjects during shunt placement for NPH.
A Randomised Controlled Trial of Lumbar Drainage to Treat Communicating Hydrocephalus After Severe...
Intracerebral HemorrhageObstructive HydrocephalusThe purpose of this study is to determine if usage of early lumbar drainage leads to less shunt surgery and less catheter associated complications in patients with communicating hydrocephalus after intracerebral hemorrhage with severe ventricular involvement.
Study to Evaluate Efficacy of Shunt Operation for Idiopathic Normal Pressure Hydrocephalus
Idiopathic Normal Pressure HydrocephalusThis study evaluates the efficacy of shunt operation for idiopathic normal pressure hydrocephalus, and determines the diagnostic value of noninvasive procedures commonly practiced in the clinic.
Hydrocephalus iPad-App Based Intervention Study
HydrocephalusHydrocephaly1 moreThis is a pilot study examining the feasibility and efficacy of using Apple iPad applications ("apps") during therapy interventions that target visual motor, visual attention, and visual-spatial reasoning skills in school age children who were previously treated surgically for hydrocephalus. Each subject will participate in an initial assessment and baseline MRI, followed by 6-weeks of iPad app-based interventions, and finally a follow-up assessment and a follow-up MRI.
Third Ventriculostomy Versus Shunt for Children With Hydrocephalus
Communicating HydrocephalusVentriculoperitoneal shunts are the standard of care for patients with communicating hydrocephalus, but they have a high failure rate - up to 40% fail within 1 year and 50% fail within 2 years. It has long been assumed that endoscopic third ventriculostomy (ETV) would not work in this population and is better suited to patients with obstructive hydrocephalus (such as from a tumor blocking cerebral-spinal fluid (CSF) pathways). However, as scientists learn more about CSF and the way our brains absorb this fluid, they have learned that this may not be so straight-forward. Recent small studies have shown that ETVs can work in a good percentage of children with communicating hydrocephalus, too. But no randomized controlled trials have been done to compare these two treatments directly to determine which will provide children with a better prognosis, fewer surgeries over their lifetime, less time in the hospital and the greatest chance at as normal a life as possible. The investigators will conduct a trial to compare these two surgical treatments where patients will be randomized to receive either a shunt or an ETV. Because ETV has been shown to have a high failure rate in newborns, the investigators will not include these patients and instead will study patients who come to Duke University with communicating hydrocephalus between the ages of 1 year and 18 years. The study will include patients with ventricular shunts who are in need of revision and patients who were just diagnosed and need their first shunt. All patients who agree to participate will be randomized to receive either an ETV or a shunt. The study team will follow them for one year from the time of the surgery and will determine what percentage of patients require further CSF-related surgeries, how long they go after their surgery before they need another surgery, how much time they spend in the hospital and what percentage of patients suffer CSF-infections or other problems related to the surgery or their hydrocephalus. The study team will examine these results and determine if ETV is a safer or more effective treatment for children with communicating hydrocephalus than is a ventricular shunt.
A Precision and Accuracy Study of the Codman Valve Position Verification (VPV) System.
HydrocephalusNormal Pressure HydrocephalusThe purpose of this study is to determine the agreement rate between the CODMAN Valve Position Verification (VPV) adjustment outcome (reprogramming) and X-ray verification in order to support an alternative to X-ray confirmation with respect to the valve adjustment process.
