RESUMO
Objective:To investigate the clinical and pathological characteristics and surgical efficacy of early brain injury with focal cortical dysplasia (FCD) IIId in children.Methods:Forty-nine children with epilepsy accepted surgical treatment in our hospital from January 2008 to July 2017 were chosen in our study; these patients were pathologically diagnosed as having FCD IIId. These children were divided into 7 groups according to different brain injuries: cerebral hemorrhage ( n=13), central nervous system infectious disease ( n=19), cerebral infarction ( n=1), intrapartum hypoxia ( n=5), two kinds of early brain injury ( n=2), febrile seizure ( n=6), traumatic brain injury ( n=3). Two years after surgery, Engel grading was used to evaluate the surgical efficacy of the children. The clinical and pathological characteristics of these children were retrospectively analyzed. Results:The average age of brain injury was 0 d-3.8 years, the average age of epilepsy was 4-5.3 years, and the average age of surgery was 7-10.2 years. The incidence of multiple lobe brain injury in the cerebral hemorrhage group (100%, 13/13) was significantly higher than that in the central nervous system infectious diseases group (36.8%, 7/19,) and febrile seizure group (50%, 3/6, P<0.05). There was a significant difference in Engel grading I ratio between cerebral hemorrhage group (84.6%, 11/13) and central nervous system infectious disease group (42.1%, 8/19, P<0.05); Engel grading I and II was noted in 80.0% children (4/5) of the intrapartum hypoxia group. All children had pathological changes and pathological characteristics of FCD after early brain injury. Conclusion:FCD IIId children with cerebral hemorrhage or intrapartum hypoxia have good surgical effect, which may be related to the early occurrence of early brain damage, clear pathological changes, and clear boundary between the focus and the surrounding brain tissues.

RESUMO
Objective@#To investigate the clinicopathologic features of Rasmussen syndrome (RS) and to raise awareness of this rare disease.@*Methods@#Clinicopathologic data of 4 cases of RS were retrospectively analyzed at Beijing Haidian Hospital from 2008 to 2016.@*Results@#The clinical manifestations included epilepsia partialis continua and progressive neurologic deficits in all patients.MRI demonstrated unihemispheric focal cortical atrophy in all cases. The histopathologic changes included variable degrees of lymphocytic infiltrate within the cortex, subarachnoid space and perivascular cuffing.Microglial nodules and neuronophagia were seen. Mild to severe neuronal loss was noted with variable degrees of reactive gliosis. Spongy edema and cavitation were observed in focal cortex. Inflammation involving hippocampus was seen in one case. Three cases were accompanied by focal cortical dysplasia (FCD) Ⅲd. Immunohistochemical staining showed that the infiltrative lymphocytes were positive for CD3, CD8, granzyme B and TIA1 and the proliferating microglial cells were positive for CD68. NeuN positive neurons decreased significantly and reactive astrocytes were GFAP positive.@*Conclusions@#Pathologic changes of RS are similar to viral encephalitis and the inflammation is progressive and multifocal involving the hemisphere. The diagnosis of RS relies on pathologic features combined with clinical findings and neuroradiological examinations.
RESUMO
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.
RESUMO
Objective To investigate the clinicopathologic features of cerebral hemisphere ulegyria in children with refractory epilepsy.Methods The clinical and pathologic findings were reviewed in 26 children who underwent resection of lesion and epileptogenic lobectomy operation in the Neurosurgery Department of Haidian Hospital,Haidian District of Peking University Third Hospital,from January 2011 to August 2015,and pathological diagnosis was cerebral hemisphere ulegyria.Results All children including 19 male and 7 female had medically intractable seizures.The mean ages of seizure onset and disease duration were 3.93 years old (from 10 days to 12 years old) and 5.42 years (from 1 month to 13 years),respectively.Eight cases had seizures because of perinatal period injury,and 12 cases developed seizures owing to infancy injury and others had no cause of disease.The mean operation age was 9.35 years old (5-14 years old).Fourteen cases underwent multilobar resection and the whole corpus callosum incision,and 12 cases were given modified anatomical cerebral hemisphere resection.The pathological diagnoses of brain tissues were cerebral hemisphere ulegyria with focal cortical dysplasia(FCD) Ⅲ d and dual pathology.Seizure outcome after the operation revealed that 19 cases (73.08%) had an Engel grade Ⅰ,3 cases (11.54%)had an Engel grade Ⅱ,2 cases (7.69%) had an Engel grade Ⅲ,and 2 cases (7.69%) missed the follow-up.Conclusions Acquired brain injury during the period of infant can cause ulegyria and cortical dysplasia,resulting in intractable epilepsy.The treatment of improved anatomical cerebral hemisphere resection and multilobar resection is significantly effective.
RESUMO
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.

RESUMO
Objective To explore the expression of Tau protein in brains of the intractable epilepsy patients and discuss its function in the pathogenesis. Methods Immunohistochemistry was adapted to test the expression of Tau protein and the mossy fiber sprouting in the hippocampus and cortex of temporal lobe from 48 intractable epilepsy patients and age-mached 48 cases of controls. Results The expression of phosphorylated Tau protein in the CA_3 areas (0.0450?0.0115) and the molecular layers of dentate gyrus (0.0463?0.0120) in intractable epilepsy patients was increased, accompanied by the hippocampus mossy fiber sprouting (3.18?0.35). No difference on the expression of total Tau protein was observed between the intractable epilepsy patients and the controls. Conclusion The present findings demonstrate that the strengthening of phosphorylated Tau protein might play an important role for the synaptic reorganization of the hippocampus. Thus, the changes of phosphorylated Tau protein could improve clinical prognosis in the intractable epilepsy patients.
