Pregnancy and Epilepsy: a Korean Tertiary Epilepsy Center Review
전지예,배진곤,Keun Tae Kim,조용원 대한의학회 2020 Journal of Korean medical science Vol.35 No.19
Background: Pregnancy in women with epilepsy (WWE) is known to have a higher risk for fetal development complications, which may include congenital malformations. Unfortunately, information pertaining to pregnancy in WWE is difficult to obtain because there are considerable ethical issues preventing these studies from being conducted on pregnant women. Therefore, this study investigated the pregnancies of Korean WWE in a tertiary epilepsy center to observe data resulting from the outcome of the pregnancies. Methods: This was a retrospective study of 48 pregnant WWE who were treated at the regional tertiary epilepsy center. All records of hospital visits before and after the period of pregnancy were analyzed to obtain information about the seizures as well as pregnancy- related outcomes, including the status of the newborns' conditions. Results: The subject group consisted of 31 (63.3%) with partial epilepsy, 6 (12.5%) with generalized epilepsy, and 11 (22.9%) with unclassified epilepsy. There were 27 subjects who took one antiepileptic drug (AED), and 12 who took two AEDs. The most commonly used drug was lamotrigine (29.8%). Of the 48 WWE involved in the study, 31 underwent caesarian sections and 17 opted for natural birth. Thirty-nine (81.3%) delivered at full-term, but 9 (18.7%) delivered at preterm. Compared to full-term infants, pre-mature infants showed lower birth weight, smaller head circumference, shorter height, and lower 1-minute Apgar scores, but seizure frequencies of the mothers did not differ. Conclusion: In WWE, epilepsy classification, number of AEDs taken, and frequency of seizures are not significantly correlated with delivery and fetal condition. This data could be used as a clinical reference for physicians to provide useful information to WWE if they are concerned about their pregnancies.
Increasing Trends in the Incidence and Prevalence of Epilepsy in Korea
전지예,이혜성,신주영,문혜진,이서영,김재문 대한신경과학회 2021 Journal of Clinical Neurology Vol.17 No.3
Background and Purpose There have been few reports on recent trends in the occurrence of epilepsy. The aim of this study was to estimate the incidence and prevalence of epilepsy and analyze their annual trends in Korea over the period 2009–2017. Methods This nationwide population-based study was carried out using the National Health Insurance Service of Korea database. A prevalent case was defined as one of a patient receiving a prescription of anticonvulsants under the diagnostic codes for epilepsy or seizure. An incident case was ascertained by confirming the absence of any epilepsy-related diagnostic codes and anticonvulsant prescription for 2 years or more before the operational definition for a prevalent case was met. Alternative operational definitions for epilepsy were tested. The temporal trends of the incidence and prevalence of epilepsy were analyzed using a Poisson regression model, and are expressed as average annual percentage changes (AAPCs). Results The incidence of epilepsy increased from 28.7/100,000 persons in 2009 to 35.4/100,000 persons in 2017. The prevalence increased gradually from 3.4/1,000 persons in 2009 to 4.8/1,000 persons in 2017. These increasing trends were more evident among elderly subjects aged ≥75 years and in those who had codes for epilepsy or seizure as an additional diagnosis. Age standardization revealed a less prominent but still increasing trend in both incidence (AAPC=0.48%) and prevalence (AAPC=3.11%). Conclusions There have been increasing trends in both the prevalence and incidence of epilepsy in Korea between 2009 and 2017. This finding appears to be related to societal aging and the high incidence of symptomatic epilepsy in the elderly population.
Cefepime-Induced Encephalopathy in a Tertiary Medical Center in Korea
전지예,조용원,문혜진 대한신경과학회 2020 Journal of Clinical Neurology Vol.16 No.3
Background and Purpose Cefepime is a widely used fourth-generation cephalosporin. It is commonly used as a first-line antibiotic to treat various infectious diseases such as hospital- acquired pneumonia, urinary tract infections, and bacterial meningitis. The primary outcome of this study was the development of cefepime-induced encephalopathy (CIE) at a tertiary medical center in Korea. We also aimed to describe the clinical features of CIE. Methods We enrolled 1,793 consecutive patients treated with cefepime. The CIE group included 44 patients who experienced altered consciousness after receiving cefepime without any other obvious cause and showed full recovery after stopping cefepime. This study collected demographic data, laboratory findings, and clinical data including the cause of infection, duration for onset of altered consciousness, duration of cefepime treatment, dosage of cefepime, duration of recovering consciousness after stopping cefepime, sequelae after encephalopathy, and electroencephalography data. Results Forty-four (2.5%) patients were included in the CIE group. The age was significantly higher in the CIE group than in the control group (71.2±10.8 years vs. 64.7±16.1 years, mean± standard deviation; p=0.007), and females constituted a significantly large proportion in the CIE group (27 of 44, 61.4%). The CIE group had higher blood urea nitrogen (34.7±22.6 mg/dL vs. 23.0±17.5 mg/dL, p<0.001) and creatinine (2.2±2.5 mg/dL vs. 1.1±1.3 mg/dL, p<0.001), and lower estimated glomerular filtration rate (eGFR) (56.3±46.0 mL/min/1.73 mm2 vs. 98.8±66.3 mL/min/1.73 mm2, p<0.001). Multivariate analysis showed that only eGFR was significantly related to CIE. Conclusions The incidence of CIE was 2.5% in this study. It is essential to consider the possibility of CIE occurring, especially in patients with lower values of eGFR and dialysis.
이상성 경과를 보이고 정맥면역글로불린 치료 후 호전된 일본뇌염
이병찬,전지예,문혜진,임정근,조용원 대한임상신경생리학회 2014 Annals of Clinical Neurophysiology Vol.16 No.1
Japanese-B viral encephalitis (JE) usually has a monophasic illness pattern. A 45-year-old woman in an altered mentalityhad improved over 1 month. About 1 week after the initial improvement, the patient became comatose with aggravatedEEG and MRI findings. Assays of cerebrospinal fluid and serum were positive for the IgM antibody to Japanese-B virus. After intravenous immunoglobulin (IVIG) infusion, the patient recovered. We report a patient with JE who showed abiphasic illness pattern and recovered after IVIG therapy. (Korean J Clin Neurophysiol 2014;16:35-38)
