Consecutive occurrence of benign epilepsy with centro-temporal spike and childhood absence epilepsy: true coexistence or atypical evolution?

引用

World Journal of Pediatrics 2018年第4期14卷 410-411页

作者： Eun Hye lee Hoi Soo yoon Department of Pediatrics College of MedicineKyung Hee UniversitySeoulKorea

We read with great interest the recent review of benign epilepsy with centro-temporal spikes (BECTS) and child-hood absence epilepsy (CAE) by Verrotti et al. (1)BECTS and CAE are the most common epilepsy syndromes in childhood and share certain clinical features: similar age at onset, overall good prognosis, and genetic predispo-sition. Several studies have reported the coexistence of the two syndromes, and recently, Verrotti et al. analyzed 19 cases reported to have clinical features of CAE and BECTS. Among the total 19 cases, three cases had fea-tures of both syndromes contemporarily;three cases expe-rienced absence seizures initially followed by BECTS;and the other 13 cases experienced BECTS at onset and had absence seizures later.

Numerical Visualization of Air Intake Induced by Free Surface Vortex

引用

Journal of Thermal Science 2017年第6期26卷 540-544页

作者： Young Kyu Park Mohan Kumar Dey yoon Hwan Choi Yeon Won lee Research Institute of Industrial Science & Technology Pukyong National University Busan Korea Interdisciplinary Program of Biomedical Mechanical and Electrical Engineering Pukyong National University Busan Korea Department of Mechanical Design Engineering Pukyong National University Busan Korea

Free surface vortex control is vital in a pump sump system because the air absorbed by free surface vortex induc- es noise, vibration, and cavitation corrosion on the pumping system. In this study, the change of free surface vor- tex and air absorption in a pump intake has been investigated by the Volume of Fraction （VOF） method with steady multiphase flow model in order to represent the behavior of the free surface vortex exactly. The homoge- neous free surface model is used to apply interactions of air and water. The results show that air intake by the free surface vortex motion can be visualized using the iso-surface of air volume fraction. The vortices make an air column from the free surface to the pump intake. Also, it was found that the flee surface vortex can be controlled by installing curtain walls.

Does antiviral therapy reduce complications of cirrhosis?

引用

World Journal of Gastroenterology 2014年第23期20卷 7306-7311页

作者： Goh Eun Chung Jeong-Hoon lee yoon Jun Kim Department of Internal Medicine Healthcare Research InstituteGangnam Healthcare CenterSeoul National University HospitalSeoul 135-984South Korea Department of Internal Medicine and Liver Research Institute Seoul National College of MedicineSeoul 110-744South Korea

Chronic hepatitis B infection is associated with the development of cirrhosis, hepatocellular carcinoma, and finally liver-related mortality. Each year, approximately, 2%-5% of patients with hepatitis B virus (HBV)-related compensated cirrhosis develop decompensation, with additional clinical manifestations, such as ascites, jaundice, hepatic encephalopathy, and gastrointestinal bleeding. The outcome of decompensated HBV-related cirrhosis is poor, with a 5-year survival of 14%-35% compared to 84% in patients with compensated cirrhosis. Because the risk of disease progression is closely linked to a patient’s serum HBV DNA level, antiviral therapy may suppress viral replication, stabilize liver function and improve survival. This article briefly reviews the role that antiviral therapy plays in cirrhosis complications, particularly, in decompensation and acute-on-chronic liver failure.

World Journal of Pediatrics 2018年第1期14卷 57-65页

作者： Ji yoon Kim Chang Ho lee Hyoung-Mi Kim Otorhinolaryngology Department CHA UniversitySeongnamKorea Otorhinolaryngology Department CHA Bundang MedicalCenterCHA University351Yatap-dongBundang-guSeongnam-siGyeonggi-do463-712Korea

Background Adenotonsillectomy (AT) has been an effective treatment for sleep-disordered breathing (SDB) in children, and several studies described the risk of postoperative weight gain and obesity in children treated with AT. The present study aimed to evaluate behavioral improvements in children with SDB one year after adenotonsillectomy and to investigate an influence of postoperative weight gain on behaviors. Methods The study included 170 children aged 5–11 years who underwent adenotonsillectomy for SDB and 150 controls. Body mass index percentile was obtained for age and gender, and parental sleep-related breathing disorder (SRBD) question-naire was used to assess the severity of SDB. Psychological assessment was performed pre- and post-adenotonsillectomy using standardized questionnaires including strength and difficulties questionnaire, children's depression inventory and screen for child anxiety-related emotional disorder. Results The mean age of 170 patients was 7.7 ± 1.5 years with 73 (42.9%) girls and 97 (57.1%) boys. The mean follow-up period were 15.4 ± 2.7 months. The patients had shown significant improvements in SDB scores as well as in questionnaire-based behavioral problems after adenotonsillectomy. The odds of a child being overweight were significantly increased after adenotonsillectomy. Less improvements in hyperactivity and conduct problems were observed in the patients with older ages, higher SRBD scores, and overweight/obesity at 1-year follow-up after adenotonsillectomy. Conclusion These data suggest that abnormal behavioral outcomes should be evaluated postoperatively, which potentially could be reduced with the early adenotonsillectomy and adequate postoperative weight control.

Monitoring of non-point source pollutants load from a mixed forest land use

引用

Journal of Environmental Sciences 2010年第6期22卷 801-805页

作者： sung Wan yoon Se Woong Chung Dong Geun Oh Jae Woon lee Department of Environmental Engineering Chungbuk National University Geum River Environmental Research Center National Institute of Environmental Research

The aim of this study was to determine the unit load of NPS （non-point source） pollutants including organic variables such as BOD （biochemical oxygen demand）, COD （chemical oxygen demand） and DOC （dissolved organic carbon）, nitrogen and phosphorus constituents, and suspended solids （SS） and their event mean concentration （EMC） of runoff flows from a water-shed of mixed forest land use by intensive field experiments. Field monitoring for continuous measurements of rainfall, flow, and water quality was conducted over 12 storm events during 2008-2009 using automated and manual sampling methods. The EMCs of individual runoff event were estimated for each water quality constituent based on the flow rate and concentration data of runoff discharge. The average EMCs of BOD, COD, DOC, SS, TN （total nitrogen）, NH4^＋-N, NO3^--N, TP （total phosphorus）, PO4^3-P from the mixed forest land were 1.794, 3.498, 1.462, 10.269, 0.862, 0.044, 0.634, 0.034, and 0.005 mg/L, respectively. The annual unit loads of BOD, COD, DOC, SS, TN, NH4^＋-N, NO3^--N, TP and PO4^3--P were estimated as 66.9, 133.2, 55.5, 429.8, 36.5, 1.6, 26.9, 1.3 and 0.1 kg/（ha·yr）, respectively. In addition, affecting parameters on the EMCs were investigated by statistic analysis of the field data. As a result, significant correlations with precipitation, rainfall intensity, and total runoff flows were found in most constituents.
