ABSTRACT
Objective To investigate the efficacy of initial polytherapy in the patients with newly diagnosed infantile spasm by evaluating the ambulatory electronecephalogram (EEG) profiles and serum neuron specific enolase ( NSE ) level.Methods Data from 108 cases of newly diagnosed infantile spasm from Sep.2007 to Nov.2010 in the Department of Pediatrics,the First Hospital of Jilin University,were respectively analyzed for the EEG profiles and serum NSE level.The patients were treated with multiple drugs.Results ( 1 )After treatment,EEG showed normal shape in 56 cases ( 62.2％ ),sporadic sharp and slow waves without hypsarrhythmia in 32 cases( 35.6％ ),and hypsarrhythmia in 2 cases (2.2％).The overall effective rate was 97.8％.(2) Serum NSE in 35 seizure-free cases were examined at the time points of hospital admission,48 hours and one month after seizure cessation,respectively.NSE level was significantly decreased at 48 hours after seizure control than that at hospital admission ( t =6.54,P ＜ 0.05 ) ; NSE at one month after seizure free was further decreased compared with that at admission point ( t =9.29,P ＜ 0.05 ).Conclusion Polytherapy for infantile spasms can ameliorate the abnormal EEGs.NSE level is decreased after seizure cessation.Intelligence is improved 6 months after seizure free and polytherapy may improve the prognosis of the children with infantile spasms.
ABSTRACT
The ambulatory EEG recorder designed in this paper can continuously record 24-hour EEG signals on 18 channels. C8051F020, a kind of mixed-signal ISP FLASH MCU, controls all the functions such as sampling, storage and many others. The 12-bit ADC in C8051F020 samples the EEG signal amplified by the preamplifier. At the same time, the EEG signal of every channel can be selected through the keyboard to be displayed on LCD so that the working status can be detected. After the system is ready, the signals sampled during 24 hours are stored into the CompactFlash card as FAT16 files.
ABSTRACT
Objective To explore the feature of epileptiform discharges during day and night in patients with sleep epilepsy and its diagnosis value. Methods Ambulatory EEG (AEEG) was performed continuously for 24 hours in 91 patients with sleep epilepsy. The frequency of epileptiform discharges in wake phase and sleep phase were analyzed. Results Epileptiform discharges were observed in 71 patients. 4 patients showed epileptiform discharges only in wakefulness, 41 only in sleep and 26 both in wakefulness and sleep. 34 patients showed epileptiform discharges only in stage 1 and 2 of NREM sleep, and 33 patients displayed epileptiform discharges in whole cycle of sleep. Seizure frequency in the patients with epileptiform discharges in wakefulness was higher than those without epileptiform discharges or with epileptiform discharges in sleep (both P
ABSTRACT
Objective To explore the value of ambulatory electroencephalography (AEEG) monitoring in diagnosis and differential diagnosis of epilepsy.Methods 24-hour AEEG in 761 patients with epilepsy and 1327 patients with paroxysmal disorder was analyzed retrospectively.Results The positive finding of epileptiform discharge by AEEG was obviously higher than routine EEG (all P
