Statistical analysis was performed by using a repeated-measures analysis of variance (ANOVA) model.Results: Mean ± SD values for NSE levels (ng/ml) were 12.5 ± 4.4 (1 h), 10.8 ± 3.8 (3 h), 11.1 ± 4.9 (6 h), and 8.2 ± 1.9 (24 h). The corresponding prolactin levels (mU/L) were 1,311 ± 1,034, 232 ± 158, 237 ± 175, and 251 ± 98. There was a significant decrease of NSE and prolactin levels over time (p < 0.001). The pair-wise comparison of NSE levels showed significant differences between the time points 1 vs. 24 h (p < 0.001), 3 vs. 24 h (p = 0.007), and 6 vs. 24 h (p = 0.009). In contrast, serum prolactin levels showed a significant difference between 1 vs. 3 h (p < 0.001) only. Most of the NSE levels remained normal after CPSs and SGTCSs. At 1 h after the seizure, only 33% of the subjects had increased NSE, whereas abnormal prolactin levels occurred with a sensitivity of 80%.Conclusions: In contrast to prolactin, serum NSE is not a sensitive marker of individual seizures. Only some individuals showed an increase of NSE beyond the prolactin-sensitive time frame after a single seizure, and mean NSE levels were not significantly increased compared with those of normal controls."],["dc.identifier.doi","10.1111/j.1528-1157.1999.tb00768.x"],["dc.identifier.gro","3151700"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8519"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0013-9580"],["dc.title","Kinetics of Serum Neuron-Specific Enolase and Prolactin in Patients After Single Epileptic Seizures"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Further, as a control, a second evaluation was made by an independent group to control for interindividual reliability of the dipole source analysis. With the realistic head model (CURRY) considering cortex, skull, and skin segmentation, the spike source was located. Methods: In five patients with mesial temporal epileptogenesis, confirmed by successful epilepsy surgery, the spike source was close to the hippocampus, with a mean distance of the dipole source from the hippocampus of 13.6 mm (range, 9-17.2 mm). In one case the ictal EEG also could be analyzed and resulted in a dipole-source localization comparable to the interictal source. Results: In both head models using either pure cortex segmentation only or a concentric three-shell model, the dipole source was systematically dislocated in a more superior position. Data analysis by a second group with independently chosen EEG samples and identical individual head model resulted in deviations of <5.3 mm. Data analysis using independently selected spikes and independently segmented head models resulted in deviations less than or equal to 16.7 mm. Conclusions: In four cases of extratemporal epileptogenesis, the origin of interictal epileptiform discharges was localized to the suspected primary epileptogenic zone."],["dc.identifier.doi","10.1111/j.1528-1157.2000.tb01508.x"],["dc.identifier.isi","000084703400013"],["dc.identifier.pmid","10643927"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/51667"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Lippincott Williams & Wilkins"],["dc.relation.issn","0013-9580"],["dc.title","Dipole-source analysis in a realistic head model in patients with focal epilepsy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In addition, the meningeal markers cystatin-C and β-trace as well as total protein were measured. Patients with trigeminal neuralgia (TN) undergoing glycerol rhizotomy served as controls. S100 protein and NSE levels ipsilateral to the site of seizure onset were significantly higher than in TN. Contralateral TLE values were also markedly but not significantly elevated. The meningeal markers cystatin-C and β-trace protein as well as total protein did not differ in TLE and TN.
