Filter by:Inborn Errors of metabolism comprise a large number of rare conditions with a collective incidence of around 1/2000 newborns. Many disorders are treatable provided that a correct diagnosis can be established in time, and for many diseases novel therapies are being developed. Without treatment, many of the conditions result in early death or severe irreversible handicaps. The Centre for Inherited Metabolic Diseases, CMMS at Karolinska university hospital, is an integrated expert center where clinical specialists work closely together with experts in laboratory medicine, combining clinical genetics, clinical chemistry, pediatrics, neurology, and endocrinology. The center serves the whole Swedish population with diagnostics and expert advice on IEM and has a broad arsenal of biochemical investigations designed to detect defects in intermediary metabolism.
This study aims to evaluate the efficacy of a ketogenic diet in treating pediatric intractable epilepsy and to explore its relationship with changes in inflammatory markers. The investigators plan to recruit 59 participants with intractable epilepsy, 39 of whom will receive a combination of ketogenic diet and conventional antiepileptic drugs, while 20 will receive only conventional drugs. The study will assess the impact of the ketogenic diet on epilepsy control and inflammatory markers, hoping to discover new treatment strategies.
This study was planned as a randomized controlled experimental study with a pretest-posttest design to determine the effect of parental supervision and video-guided progressive relaxation exercise (PRE) and music recital on sleep, quality of life and emotional states in children with epilepsy aged 9-16 years. The main questions it aims to answer are as follows: According to the evaluation of children with epilepsy, does the progressive relaxation exercise applied to children have an effect on sleep, quality of life and emotional states? According to the evaluation of children with epilepsy, does music recital applied to children have an effect on sleep quality of life and emotional states? The study consisted of 45 children (15 children in the progressive relaxation exercise group, 15 children in the music recital group and 15 children in the control group). Ethics committee approval, permission from the institutions and informed consent of the children were obtained for the conduct of the study. A value of p<0.05 was considered statistically significant in data analysis.
This study investigates the usefulness of high resolution electrical source imaging (HR-ESI) in the setting of presurgical evaluation of drug-resistant focal epilepsy in children. This method is based on an estimation of the intra-cerebral source that produces a signal recorded by scalp electrodes by solving the inverse problem, taking into account attenuation factors resulting from particular conductivity properties of the cerebral, peri-cerebral and cranial tissues. Electrical sources are then fused on structural magnetic resonance imaging (MRI). Scalp EEG recorded using 64 to 256 electrodes refers to as high resolution EEG (HR-EEG), leading to HR-ESI. Studies based on small population of children or on mixt population of children and adults showed that HR-ESI has accuracy values, i.e. percentage of true positives (electrical source localized in the brain area resected and success of surgery) and true negatives (electrical source localized outside the brain area resected and failure of surgery) among the total population, ranging from 50 to 80%. Discrepancies between studies could be explained by the limited number of patients included or by the mixture of pediatric and adult data. Another limitation of previously published studies is that the spatial pattern of dipole source distribution was not taken into account to determine prediction accuracy of ESI. Studies using magnetoencephalography (MEG) to perform magnetic source imaging (MSI) suggest that the spatial pattern of dipole source distribution needs to be considered, a spatially-restricted dipole distribution being associated with better post-surgical outcome when resected. To tackle these issues, the investigators aim to conduct the first large prospective multicentric study in children with focal epilepsy candidates to surgery to assess prediction accuracy of ESI based on the finding of tight clusters of dipoles. This is original as this pattern (tight versus loose cluster of dipoles) has been studied by several researchers using MEG but not using HR-EEG. The investigators make the hypothesis that HR-EEG will allow to identity good candidates for epilepsy surgery and thus to offer this underutilized treatment in more children with better post-surgical outcome. Among the secondary objectives, the investigators will address methodological issues related to the resolution of the inverse problem (methods using distributed sources models versus methods based on equivalent dipole estimation), the potential added value to model high-frequency oscillations (HFO), and the investigators will assess the cost-utility of the HR-ESI procedure.
Currently, mapping the epileptogenic zone is based on a comprehensive preoperative assessment involving clinical, imaging and electrophysiological examinations. To reduce the need for invasive stereoelectroencephalography (SEEG) explorations, electrophysiological and imaging methods have been developed, such as resting-state functional MRI (fMRI) coupled with electroencephalogram and arterial spin-labeling perfusion MRI (ASL-MRI). It has been published that these new methods enable precise delineation of the epileptogenic zone and better preparation for surgery. The aim is to determine whether, in children with focal lesional epilepsy, the combination of ASL-MRI-EEG and resting-state fMRI-EEG enables precise identification of the epileptogenic zone to be defined by SEEG, the current reference examination.
This study is being done to find out if a smartphone app can identify absence seizures. Children who have a history of absence seizures, as well as children without any seizure history, will be testing out the app. If participating the child will be guided through hyperventilation, an activity that asks the child to take quick, deep breaths. The app will record video of the child's face and sounds they make during hyperventilation. Hyperventilation is a safe and established technique frequently used during EEG (electroencephalogram) to encourage seizure occurrence. The App will be used during a regularly scheduled EEG.
The effect of sulthiame on EEG has been studied in epilepsy syndromes of childhood with sleep activation by comparing sleep EEG obtained at baseline and after 4 weeks of treatment. The aim of the study is to know if an effect is still identifiable after 2 weeks of treatment by performing sleep EEG recordings after 2 and 4 weeks of treatment, respectively.
The proper period of anti-seizure medication (ASM) treamtment is important for decreasing side effect of ASM and recurrence of seizure. We evaluate reliable risk factor analysis for safe withdrawal of ASM in children with epilepsy. Futhermore, we develop the scoring system for prediction of seizure recurrence to set the standard for safe withdrawal of ASM.
The hematologic consequences of novel Anti-seizure medications (ASMs) are rarely reported. Whether coagulation dysfunctions increase the risk of peri-operative bleeding remains controversial. The research is performed to investigated the incidence and risk factors of preoperative coagulation dysfunction in children undergoing surgery for epilepsy and their impact on surgery.
The purpose of this study is to evaluate the effect of melatonin for improving sleep in pediatric epilepsy.
