Filter by:The investigators aim to identify the frequency with which an elective brain MRI yields and etiologic diagnosis to explain its indication. The protocol includes children undergoing elective brain MRI with anesthesia prior to their third birthday.
This study is designed as a prospective, non-randomized, observational, multicenter clinical trial. The primary aim of this study is to observe if the use of the rapid responds electroencephalography (EEG) system impacts physician decision making. Secondary aims include exploring the safety and performance information of the Ceribell EEG system compared to conventional EEG system. The study will recruit physicians (Faculty physicians and Trainees) at up to five institutions and examine the impact of rapid response EEG when providing care to patients in whom EEG recording has been ordered for clinical reasons.
Electroencephalography (EEG) records electric activity of the brain using electrodes placed on the scalp. EEG is an important tool in the diagnostic work-up of patients with epilepsy. Specific types of sharp EEG discharges (epileptiform discharges) are associated with patients with epilepsy. The International Federation of Clinical Neurophysiology (IFCN) has recently published a set of six operational criteria for identifying epileptiform discharges. At least four criteria need to be present in order to classify a discharge as epileptiform. These criteria are largely based on expert opinion and have not been validated yet. It is not clear what the sensitivity and specificity of these criteria are, and which combination of these criteria are optimal. Each criterion is based on visual assessment. However, it is not known what the inter-rater agreement of these criteria are. EEG is traditionally inspected in sensor space, i.e. in the recording channels. Advances in signal analysis made possible reconstructing the electric currents in the regions of the brain generating them, and displaying the signals in the source space, instead of the sensor space. The objectives of this study are: to determine the inter-rater agreement of the IFCN criteria by visual analysis in sensor space, to determine the combination of criteria with the best accuracy (sensitivity and specificity) and assess the accuracy of evaluating the discharges in source space. The raters will analyze EEG recordings from 100 patients, from two groups: consecutive patients with epilepsy and consecutive patients with non-epileptic paroxysmal episodes. EEG was recorded during long-term video-EEG monitoring. As reference standard, the investigators used the evaluation of the patients´ habitual clinical episode. The performance of the criteria in sensor-space and the analysis in source space will be compared with the unrestricted expert scorings.
The 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.
Febrile seizures(FS) are the most common neurological disorder in chilhood and are a great stress for parents due to their dramatic clinical appearance. Using HRC-test(test for determination of homozygously recessive characteristics in humans) we analyzed presence, distribution, and individual combination of 20 selected genetically controlled morpho-physiological traits among FS patients and control to determine a possible deviation in the homozygosity level and genetic loads in the group of affected children and whether there is a predisposition to the occurrence of FS.
In this study, we will explore the feasibility of a randomized controlled trial that will compare high protein dose from ICU day 6 to 14 with moderate protein intake.
This is a multi-center, double-blind, randomized, parallel group, dose-ranging study to investigate the efficacy and clinical usability of STAP-001 in adult (18 years of age and older) subjects with epilepsy with a predictable seizure pattern. These subjects have an established diagnosis of focal or generalized epilepsy with a documented history of predictable seizure episodes. This is an in-patient study. The subjects will be admitted to a Clinical Research Unit (CRU) or Epilepsy Monitoring Unit (EMU) for study participation. The duration of the stay in the in-patient unit will be 2-8 days. One seizure event per subject will be treated with study medication. The duration and timing of the seizure event and occurrence of subsequent seizures will be assessed by the Staff Caregiver(s)1 through clinical observation and confirmed with video electroencephalogram (EEG).
The investigators aim to determine the feasibility of using the Medtronic LINQ device for epilepsy diagnosis, monitoring and management. The feasibility will be determined by comparing EEG signals from the LINQ system to the gold standard clinical recordings. If seizures can be identified using the LINQ device with the same level of accuracy as adjacent scalp EEG recording electrodes, then the LINQ will be deemed feasible.
This is a two-part study that aims to determine the reliability and safety of the use of the Hövding inflatable helmet in seizures, as evidenced by the deployment of the helmet during seizures, and qualitative patient reporting.
This is a Phase 2a, open-label study consisting of a screening period of up to 4 weeks and a 4-dose-titration treatment period to a dose of up to 10 mg twice daily (BID) of CX-8998, followed by a 1-week safety follow-up period after the last dose of study medication.
