We were not able to show an efficacy of cervical spine manipulation in 52 children and adolescents.

The most effective drugs in patients with PCDH19 mutations were bromide and clobazam. Although epilepsy in PCDH19 mutations is often pharmacoresistant, three quarters of the patients became seizure-free for at least for 3 months and half of them for at least one year. However, assessing the effectiveness of the drugs is difficult because a possible age-dependent spontaneous seizure remission must be considered.

Summary:Purpose: Valproic acid (VPA) is an antiepileptic drug (AED) commonly used for generalized and focal epilepsies. We provide an update on hepatotoxic side effects in Germany between 1994 and 2003.Methods: We mailed a questionnaire to all members of the German Section of the International League Against Epilepsy, asking for VPA-induced side effects, especially severe side effects such as hepatopathy.

SUMMARYPurpose: Data on epileptiform electroencephalography (EEG) discharges in healthy children are limited, with published studies dating back more than 20 years. Moreover, analyses have been performed exclusively using paperrecorded EEG, and reported prevalences differ significantly. With recent reports using these data as reference suggesting an increased prevalence of epileptiform EEG discharges in children with behavioral disturbances, acquisition of exact prevalence data has become even more critical. The aim of our study was to analyze the frequency of epileptiform EEG discharges in healthy children using digitally recorded EEG (DEEG) and to compare these data to those of previously published studies. Methods: Prospective analysis of DEEG was performed in 382 healthy children (226 male, 156 female) ages 6-13 years admitted to our hospital for minor head trauma. Recording was carried out for a minimum of 20 min including hyperventilation and photic stimulation.Analysis was carried out by two board-certified clinical neurophysiologists. Results: Epileptiform EEG discharges were detected in 25 of 382 children (11 of 226 male, 14 of 156 female) corresponding to an overall prevalence of 6.5%. Of these 25 children, 4 had either generalized or bifrontal spikes, 12 showed constant localized focal discharges, and 9 showed multifocal discharges. Compared to previous studies using non-DEEG recording, the prevalence of epileptiform EEG discharges in our population was significantly higher. No significant difference was found when comparing our data to prevalences recently reported in children with behavioral disturbances using DEEG. Conclusions: Our study further highlights the urgent need to reevaluate the prevalence of epileptiform EEG discharges in healthy children using DEEG recordings in a large cohort.

There are conflicting results concerning bone metabolism in children receiving antiepileptic medication, with data concentrating on neurologically impaired patients. We performed a multicenter cross-sectional study in otherwise healthy children who received monotherapy with valproic acid, oxcarbazepine, lamotrigine, sulthiame, levetiracetam, or topiramate for at least 6 months. Data on calcium, phosphorus, alkaline phosphatase, 25-OH vitamin D, and parathormone were collected. Among 128 patients, 24.4% had hypocalcemia, 25.4% hypophosphatemia, and 13.3% (n = 17) 25-OH vitamin D levels <10 ng/mL. All patients were clinically asymptomatic. Mean calcium concentrations were found to be significantly lower among the study population (2.41 mmol/L) compared with healthy controls (2.53 mmol/L). Lowest mean concentration was observed in patients treated with sulthiame followed by oxcarbazepine and valproic acid. No influence of calcium intake or therapy on bone metabolism was noted. Effects on bone metabolism of anticonvulsive monotherapy are not restricted to neurologically impaired children but also affect otherwise healthy children.

Our follow-up study shows that Alice-in-Wonderland is most likely a benign, self-terminating childhood condition, although occasional recurrences of symptoms are possible.
