Refractory gelastic seizure is one of the most common clinical manifestations in patients with hypothalamic hamartoma (HH) and HH is usually regarded as the epileptogenic focus. A young female patient with a small HH and refractory seizures is reported here. However, both the seizure semiology and results of electroencephalogram monitoring indicated the(More)
A study of the propagation of electroencephalogram (EEG) activity before seizure by means of the Directed Transfer Function (DTF) is presented. The DTF method is a multi-channel parametric method of analysis based on an autoregressive model, and is capable of supplying such information as the direction, spectra and dynamics of the propagation of EEG(More)
Despite the drive towards evidence-based practice, the extent to which research evidence is being implemented in nursing practice is unclear, particularly in developing countries. This study was to assess the levels of perceived barriers to and facilitators of research utilization in practice among Chinese nurses and inter-relationships between these(More)
Gelastic seizure is an uncommon type of seizure which is characterized by recurrent bouts of unprovoked and stereotyped laughter. It is commonly observed in patients with hypothalamic hamartoma, while its association with other cerebral lesions is rare. The patient was a 15-year-old right-handed male. His chief complaints were recurrent onsets of laughter(More)
OBJECTIVE To explore the application of intracranial electrodes (IE) for temporal lobe epilepsy (TLE) surgery and assess the clinical utility of intracranial video electroencephalography (IVEEG). METHODS The clinical data of 60 TLE patients undergoing implantation of IE were reviewed retrospectively. Cortical subdural strip, grids and depth electrodes(More)
BACKGROUND The findings of previous studies remain controversial on the optimal management required for effective seizure control after surgical excision of arteriovenous malformations (AVMs). We evaluated the efficacy of additional bipolar electrocoagulation on the electrically positive cortex guided by intraoperative electrocorticography (ECoG) for(More)
OBJECTIVE To explore the clinical features of hippocampal lesions. METHODS the clinical data of 21 patients with hippocampal lesions, 15 males and 6 females, aged 19 (8-42), with a duration of mesial temporal lobe epilepsy (MTLE), underwent resection of the anterior temporal lobe, amygdaloid nucleus, and hippocampus. The resected hippocampal tissues were(More)
OBJECTIVE To find morphological changes of synapses related to the spike discharge by observation on ultrastructures of the EEG spike foci of cerebral cortexes. MATERIAL AND METHODS The cerebral cortexes were obtained surgically from the EEG spike (recorded by flaky silver electrodes on the surface of cortexes) foci and nonspike areas within the limits of(More)
