Background: The ketogenic diet (KD) can be effective in reducing seizures in children. Predictors of success have not been identified yet.
Aims: To evaluate efficacy of KD treatment and to search for child- or diet-related factors that can predict its efficacy at 12 months follow-up.
Background: Neuropsychological deficits after treatment of paediatric brain tumour are well known, but not the role of hydrocephalus in these deficits.
Aims: To study long-term neurological, cognitive, and behavioural deficits in children with a low grade tectal tumour and acquired obstructive hydrocephalus.
Methods: In a consecutive series of 12 children with low-grade tectal tumour diagnosed in our hospital between 1994 and 2008, neurologic, neuropsychological, and radiologic data were prospectively collected.
The objective of this study was to examine the validity of the diagnosis of "febrile seizure" as reported by parents. The study was embedded in a population-based prospective cohort study. Information on paroxysmal events was obtained by screening questions at ages 1, 2, and 3 years.

Method: This work was performed in the Generation R Study, a population-based cohort study in Rotterdam from early fetal life onwards.
Objective: Monocarboxylate transporter 8 (MCT8) is an essential thyroid hormone (TH) transporter as humans with MCT8 mutations have severe neurological and endocrine abnormalities. The objectives are (i) to identify novel MCT8 mutations and (ii) to assess their functional relevance; (iii) to describe the effects of block-and-replace treatment in an MCT8 patient.
Design: The TOP-R study is a cross-sectional nation-wide multicentre study.
Aim: To examine the association between the number of fever episodes and the risk of febrile seizures.
Methods: This study was embedded in a population-based prospective cohort study from early foetal life onwards. Information about the occurrence of febrile seizures and fever episodes was collected by questionnaires at the ages of 12, 24 and 36 months.
Aim: To evaluate survival, clinical, and genetic characteristics of all patients with classic or type 1 lissencephaly born between 1972 and 1990 in the Netherlands, who at the time were enrolled in an observational study.
Method: We re-evaluated 24 patients (11 males, 13 females) for long-term follow-up and survival information.
Results: Mean length of follow-up was 14 years (SD 9 y 8 mo).
Objective: The goal was to examine the associations between fetal growth characteristics in different trimesters of pregnancy and the occurrence of febrile seizures in early childhood.
Methods: This study was embedded in a population-based, prospective, cohort study from early fetal life onward. Fetal growth characteristics (femur length, abdominal circumference, estimated fetal weight, head circumference, biparietal diameter, and transverse cerebellar diameter [TCD]) were measured with ultrasonography in the second and third trimesters of pregnancy.
Purpose: To determine long-term outcome in a cohort of children with newly diagnosed benign childhood epilepsy with centrotemporal spikes (BECTS).
Methods: 29 children with BECTS were included in the Dutch Study of Epilepsy in Childhood. Each child was followed for 5 years, and subsequently contacted 12-17 years after enrolment to complete a structured questionnaire.
Aim: To examine the incidence of paroxysmal epileptic and non-epileptic disorders and the associated prenatal and perinatal factors that might predict them in the first year of life in a population-based cohort.
Method: This study was embedded in the Generation R Study, a population-based prospective cohort study from early fetal life onwards. Information about the occurrence of paroxysmal events, defined as suddenly occurring episodes with an altered consciousness, altered behaviour, involuntary movements, altered muscle tone, and/or a changed breathing pattern, was collected by questionnaires at the ages of 2, 6, and 12 months.
This study reports results of therapy with immunoglobulin in children with Landau-Kleffner syndrome (LKS) or the syndrome of continuous spikes and waves during sleep (CSWS syndrome). In a prospective study, children diagnosed between 2002 and 2006 with either LKS or CSWS syndrome were treated soon after diagnosis with intravenous courses of immunoglobulin (IVIg). We compared the results with those reported in the literature and with data from a retrospective survey of our earlier patients.

All children were followed for 12-17 years. The children were subdivided in three groups for the analyses: those becoming seizure-free (I) within 1 month after enrolment; (II) 1-6 months after enrolment; and (III) more than 6 months after enrolment or having seizures continuing during follow-up.

Recently, it was shown that statin-mediated inhibition of 3-hydroxy-3-methylglutaryl coenzyme A reductase restores the cognitive deficits in an NF1 mouse model.
Objective: To determine the effect of simvastatin on neuropsychological, neurophysiological, and neuroradiological outcome measures in children with NF1.

Introduction: Many data on the course and prognosis after provoked and unprovoked single and multiple seizures in childhood have been collected in the past decennia by prospective, large-scale, long-term observational cohort studies. These data may serve to guide treatment decisions and help to design controlled trials investigating treatment strategies in childhood epilepsy.
Methods: The results of the Dutch study of epilepsy in childhood will be compared with those of other studies.
Purpose: To study the efficacy and tolerability of add-on levetiracetam in children and adolescents with refractory epilepsy.
Methods: In this prospective multi-centre, open-label, add-on study, 33 children aged 4-16 years (median 8.5 years) with epilepsy refractory to at least two antiepileptic drugs were treated with levetiracetam in addition to their present treatment regimen with a follow-up of 26 weeks.
Purpose: To validate two prognostic models for childhood-onset epilepsy designed to predict a terminal remission of <6 months at 2 years after diagnosis in children referred to the hospital.
Methods: A hospital-based cohort of children with newly diagnosed epilepsy was recruited and followed up for 2 years to validate previously developed models. One model was based on variables collected at intake, and the other was based on intake variables plus variables collected during the first 6 months of follow-up.

Background: Most end-of-life decision-making studies have, until now, involved either the general population or newborn infants.
Objective: To assess the frequency of end-of-life decisions preceding child death and the characteristics of the decision-making process in the Netherlands.
Methods: Two studies were performed.
The efficacy of a combination of midazolam and phenytoin in treating generalized convulsive status epilepticus in children was studied retrospectively. The patient group comprised all patients admitted for generalized convulsive status epilepticus to the pediatric intensive care unit over 7 years. Patients treated according to the protocol were included (N = 122).

His parents had not been diagnosed previously with CMT, but on careful examination they showed clinical signs of CMT and reduced nerve conduction velocities. Genetic analysis identified the boy as a heterozygote for both a peripheral myelin protein 22 (PMP22) duplication and a mutation in the lipopolysaccharide-induced-tumour-necrosis-factor-alpha-factor (LITAF) gene, whereas each parent only had one mutated CMT gene.

This study aimed to define the prospects of newly diagnosed childhood epilepsy, assess the dynamics of its course, identify relevant variables and develop models to assess the individual prognosis. Four hundred and fifty-three children with newly diagnosed epilepsy were followed for 5 years.

View Article and Find Full Text PDFWe used a parent-completed 20-item "side effect scale" quantifying complaints that parents perceive to be caused by antiepileptic drugs (AEDs) in 108 children with active epilepsy. We studied the associations between parent-reported complaints, severity of seizures, and restrictions due to epilepsy, and clinical data including number and AED load. In 85% of the children at least one complaint was reported, in less than 20% complaints were perceived as a substantial problem.
