RESUMEN
Objective To study the outcomes of Lennox-Gastaut syndrome (LGS) with single-stage total corpus callosotomy combined with different resective surgeries. Methods Nine LGS patients, admitted to our hospital from May 2010 to May 2014, were chosen in our study. Their clinical data were retrospectively analyzed. According to the results of anatomy, electrophysiology and clinical comprehensive evaluation, all the 9 children received single-stage total corpus callosotomy combined with different resective operations. The differences of epileptic seizures of these children before and after surgery were compared. Results The 9 LGS children were followed up for 2 years;5 achieved Engel grade I, 3 achieved Engel grade II, and one achieved Engel grade III. The surgical effective rate was 88.9％ (8/9). The frequencies of drop seizures, convulsive seizures, tonic seizures and tonic-clonic seizures were decreased of different degrees, with drop seizures enjoying the best control. Three patients had transient silence, remarkable relief one week after surgery and total recovery half year after surgery. Conclusion Early single-stage total corpus callosotomy combined with different resective operations can help to control seizures in children with intractable LGS.
RESUMEN
Objective Sylvian Veins morphology analysis contributes to cortex veins protection for clear surgical fields, a better choice for operation plan evaluation. Methods 33 cases diagnosed as epilepsy, male∶female=19∶14, mean ages 18.7y (9-52). Results 4 types of Sylvian Veins spreading were observed from the procession of functional surgery: long stem pattern 49%(16/33), short stem pattern 15%(5/33), long truncks pattern 33%(11/33), and absent stem pattern 3%(1/33). Conclusion Sylvian Veins morphology analysis shows that there exist 4 main patterns, which may contribute to functional surgery about frontal operculum, temporal operculum and insular lobe or intracranial electrode placement.
RESUMEN
Objective To identify the cellular distribution of a my elin-associated protein (Nogo-A) in the central nervous system (CNS) of mice a nd explore its possible inhibition on the CNS axon regeneration after spinal cor d injury. Methods Brain, spinal cord, peripheral tissues and w eight-dropping injuried spinal cord from the adult C57BL/6 mice were studied. N ogo-A protein expression was localized immunohistochemically. Chick E12DRG neur ons were cultured and growth cone collapse assessed. Results N ogo-A protein expression detected was mainly in the oligodendrocyte cell body a nd the myelinated axons surrounded by cell processes rather than in the peripher al tissues. After spinal cord injury, Nogo-A was up-regulated at a moderate de gree in the area around the lesion. Chick E12 DRG growth cone collapse rate was as high as 70%, significantly higher than that in the blank control and vector control groups with a significant difference ( P
