Recently, new designaed spinal fixation device using pedicle screw was introduced and there was a trend to use this posterior short segment instrumentation. In the surgical treatment of unstable thoracolumbar spine. various methods of instrumentation have been used for stabilization of the spine. correction of deformity and reductin of fracture. painless mobilization. A further aim is to avoid late malposition and to preserve mobility. Simultaneously. it provides immediate postoperative rehabilitation without rigid external support. The authors have treated 31 cases of unstable thoracolumbar spine using VSP and C-D instrumentation at our hospital from May 1989 to March 1992. We reported the result of clinical analysis of those system.

Usefulness of Transient Elastography for Non-Invasive Diagnosis of Liver Fibrosis in Pediatric Non-Alcoholic Steatohepatitis

권영대,고경옥,임재우,천은정,송영화,윤정민 대한의학회 2019 Journal of Korean medical science Vol.34 No.23

Background: Transient elastography (FibroScan®) is a non-invasive and rapid method for assessing liver fibrosis. While the feasibility and usefulness of FibroScan® have been proven in adults, few studies have focused on pediatric populations. We aimed to determine the feasibility and usefulness of FibroScan® in Korean children. Methods: FibroScan® examinations were performed in 106 children (age, 5–15 years) who visited the Konyang University Hospital between June and September 2018. Liver steatosis was measured in terms of the controlled attenuation parameter (CAP), while hepatic fibrosis was evaluated in terms of the liver stiffness measurement (LSM). Children were stratified into obese and non-obese controls, according to body mass index (≥ or < 95th percentile, respectively). Results: The obese group was characterized by significantly higher levels of aspartate aminotransferase (AST, 57.00 ± 48.47 vs. 26.40 ± 11.80 IU/L; P < 0.001) and alanine aminotransferase (ALT, 91.27 ± 97.67 vs. 16.28 ± 9.78 IU/L; P < 0.001), frequency of hypertension and abdominal obesity (abdominal circumference > 95% percentile) (P < 0.001), CAP (244.4–340.98 dB/m), and LSM (3.85–7.77 kPa) (P < 0.001). On FibroScan®, 30 of 59 obese children had fibrosis (LSM > 5.5 kPa), whereas the remaining 29 did not (LSM < 5.5 kPa). Obese children with fibrosis had higher levels of AST (73.57 ± 56.00 vs. 39.86 ± 31.93 IU/L; P = 0.009), ALT (132.47 ± 113.88 vs. 48.66 ± 51.29 IU/L; P = 0.001), and gamma-glutamyl transferase (106.67 ± 69.31 vs. 28.80 ± 24.26 IU/L; P = 0.042) compared to obese children without fibrosis. LSM had high and significant correlation (P < 0.05) with AST, ALT, homeostasis model assessment for insulin resistance, and AST-to-platelet ratio index. Conclusion: FibroScan® is clinically feasible and facilitates non-invasive, rapid, reproducible, and reliable detection of hepatic steatosis and liver fibrosis in the Korean pediatric population.

급성 뇌경색 환자의 증상 발현 후 응급실 도착까지의 시간이 치료 결과에 미치는 영향

권영대,윤성상,장혜정,Kwon, Young-Dae,Yoon, Sung-Sang,Chang, Hye-Jung 대한예방의학회 2007 예방의학회지 Vol.40 No.2

Objectives : Recent educational efforts have concentrated on patient's early hospital arrival after symptom onset. The purpose of this study was to evaluate the time interval between symptom onset and hospital arrival and to investigate its relation with clinical outcomes for patients with acute ischemic stroke. Methods : A prospective registry of patients with signs or symptoms of acute ischemic stroke, admitted to the OO Medical Center through emergency room, was established from September 2003 to December 2004. The interval between symptom onset and hospital arrival was recorded for each eligible patient and analyzed together with clinical characteristics, medication type, severity of neurologic deficits, and functional outcomes. Results : Based on the data of 256 patients, the median interval between symptom onset and hospital arrival was 13 hours, and 22% of patients were admitted to the hospital within 3 hours after symptom onset. Patients of not-mild initial severity and functional status showed significant differences between arrival hours of 0-3 and later than 3 in terms of their functional outcomes on discharge. Logistic regression models also showed that arrival within 3 hours was a significant factor influencing functional outcome (OR=5.6; 95% CI=2.1, 15.0), in addition to patient's initial severity, old age, cardioembolism subtype, and referral to another hospital. Conclusions : The time interval between symptom onset and hospital arrival significantly influenced treatment outcome for patients with acute ischemic stroke, even after controlling for other significant clinical characteristics. The findings provided initiatives for early hospital arrival of patients and improvement of emergency medical system.

This study has been undertaken on attitude of members of quality assurance committees by sending questionnaires through the mail to survey on their understanding of the concept of quality assurance, recognition of the need of implementing quality assurance policy, evaluation of the present quality assurance activities and opinions of future directions of quality assurance. The result of this study is as follow : Respondents appeared to be understanding the concept of quality assurance as the concept of 'the best quality of care' and take very high recognition of the need of implementing quality assurance policy. They provided negative answer in evaluating performance of quality assurance committee, defining the main cause as the lack of understanding and poor capacity of physicians for quality assurance. In addition, indicated from their attitude was to have medical professionals be the main body of implementation for quality assurance in the future.

Objectives : To estimate the weighting for the disability caused by major cancers in Korea using the Delphi method. Methods : We selected 19 panelists to estimate the disability weighting of major cancers in Korea by using the Delphi method. To select the relevant kinds of cancers, we used National Death Certificate Data produced by the National Statistical Office in 1996. Then the stability of each delphi round was calculated by using the coefficient of variance. Results : The disability weight of major cancers for males was pancreas cancer(0.36), liver cancer(0.35), esophageal cancer(0.30), stomach cancer(0.27), lung cancer(0.26), and colorectal cancer(0.30). The disability weight of major cancers fer females was pancreas cancer(0.36), liver cancer(0.34), esophageal cancer(0.29), stomach cancer(0.28), lung cancer(0.26), and colorecial cancer(0.28). Conclusion : The results of this study will provide baseline data useful for the measurement of the burden of disease caused by cancers in Korea.

권영대,지은미,박규택 한국동물분류학회 2010 Animal Systematics, Evolution and Diversity Vol.26 No.1

A notodontid moth, Disparia diluta (Hampson, 1910) is reported for the first time from the Korean peninsula. At the same time, taxonomical note for D. nihonica (Wileman, 1911) is given. The male genitalia of D. nihonica (Wileman) were erroneously illustrated as those of Neodrymonia delia (Leech) by Tshisjakov and Kwon (1999),and Schintlmeister (2008) cited D. nihonica (Wileman) to be distributed in the Korean peninsula, based on the illustration.
