수술 후 초래되는 뇌졸중은 그 빈도가 매우 드문 것으로 알려져 있다. 저자들은 자궁 근종으로 인한 월경 과다와 월경 곤란증을 주소로 내원한 47세 여자 환자에게 전신 마취 하에 실시한 전자궁 적출술 후 발생한 뇌 경색 1예를 문헌 고찰과 함께 보고하는 바이다. We report a case of acute cerebral infarction after a total abdominal hysterectomy. A 47 year old female patient had suffered from hypermenorrhea and dysmenorrhea due to myoma of uteri for about 1 year. Preoperatively, anesthesiologist and gynecologist visited and evaluated her but any suspicious symptoms related to cerebral infarction was not found. Her past history was non-specific. Anesthesia was induced with thiopental and succinylcholine and maintained wish pancuronium-enflurane-nitrous oxide -oxygen. Postoperatively, she fell into coma and showed abnormal neurologic signs, so she was diagnosed as acute cerebral infarction of middle cerebral artery territory by brain CT, and ultimately expired.

Purpose: This study evaluated the glycemic response of diets using estimated glycemic load (eGL), which had been developed for mixed meals for Korean adults, and examined its associations with cardiometabolic risk factors among Korean adults. Methods: A total of 4,655 men and 6,760 women aged 19 years and above were included from the 2013~2016 Korea National Health and Nutrition Examination Survey. eGL was calculated by each meal (breakfast, lunch, dinner, and snack) and then summed to give daily total eGL. A multiple logistic regression analysis was used to examine the association. Results: Mean daily total eGL was 112.6 in men and 99.3 in women. Daily total eGL was positively associated with carbohydrate and fiber intakes, but negatively associated with protein and fat intakes in both men and women (p<0.05 for all). Daily total eGL showed an inverse association with HDL-cholesterol level in both men and women (p=0.0036 for men and p=0.0008 for women). Men in the highest quintile of daily total eGL showed a 66% increased risk of hypercholesterolemia (OR, 1.66; 95% CI, 1.10~2.50; p for trend=0.0447) compared with those in the lowest quintile. Conclusion: These findings suggest that eGL based on carbohydrate, protein, fat and fiber intakes can reflect glycemic response and therefore can be used as an index for dietary planning, nutrition education and in the food industry.

Severe hypercarbia can develop for unidirectional valve malfunction and may go undetected during anesthesia. A 29-year-old male patient with history of bronchial asthma underwent tonsillectomy and septorhinoplasty due to chronic tonsillitis, depressed bulbous, and deviated septum of nose. Anesthesia was induced with thipental-vecuronium and maintained with enflurane-N2O-O2 in a semiclosed circle system. We experienced a case of severe hypercarbia from replacement with an incorrect expiratory valve.

오디 조임근 기능이상을 동반한 간질 감염

간질증은 주로 소나 양 같은 초식 동물의 간담관에 기생하는 흡충인 간질에 의한 인수공통 감 염증 으로 사람은 주로 간질의 피낭유충에 오염된 수생 식물을 먹음으로써 감염된다. 이러한 간질 증은 간 농양, 담관염, 담관 폐쇄 등을 유발할 수 있다. 저자들은 원인을 모르는 심와부 통증과 호 산구 증가를 동반했던 42세 여자에서 오디 조임근 내압 검사를 통하여 오디 조임근 기능이상을 진 단 및 내시경 조임근 절개술을 시행하였으나 임상적 호전이 없어 혈청 항체를 통해 간질증을 진 단하 였다. 간질증의 치료 약제인 triclabendazole과 bithionol은 전세계적으로 구하기 힘들고 albendazole과 praziquntel의 효과는 낮은 것으로 보고되고 있는데 본 증례에서는 국내에 서 구 하기 쉬운 albendazole과 praziquntel을 우선 투여하고 임상적 호전이 없어 nitazoxanide 를 투 여하고 경과 관찰 중에 있다. 간질증의 치료 약제로 알려져 있지만 국내에서 사용했던 보고 가 없 는 nitazoxanide를 시도하였고 오디 조임근 기능이상이 간질증에 의해 일어날 수 있음을 시 사하 여 본 증례의 의미가 크다고 본다. Fascioliasis is a zoonotic infection by Fasciloa hepatica, a liver fluke that infests cattle and sheep. Humans are infected by eating water plants contaminated with metacercariae. Fasciola hepatica causes liver abscess, cholangitis, common bile duct obstruction and so on. We report a 42-year-old woman who presented with epigastric pain radiating to back and eosinophilia. During follow-up period, liver function was worsen transiently and abdominal computed tomography showed hypodense area in caudate lobe. She was diagnosed with sphincter of Oddi dysfunction on manometry. Endoscopic sphincterotomy was conducted, but epigastric pain was not changed. Additionally we diagnosed fascioliasis serologically. Triclabendazole, treatment of cholice for fascioliasis, cannot be got all over the world. We have tried albendazole and praziquantel, but clinical improvement was not observed. Recently nitazoxanide was given to her, and we are observing clinical course. This report suggests that sphincter of Oddi dysfunction can be caused by fascioliasis.

Nutritional support in intensive care unit (ICU) patients is important because it is related with clinical prognosis. We investigated the nutritional support in ICU patients and compared it with evidence-based guidelines. To improve nutritional support, we used the protocol and evaluated its effect. Nutritional data were collected from ICU patients before and after the application of protocol (controls,n = 46; intervention group, n = 41). Until the 72 hours after admission, calorie and protein were supplemented mainly with intravenous nutrition. Since then, the proportion of enteral nutrition (EN) has been to increase. Among 42% of patients who had not taken EN on the 3rd day, we did not find any reasons about that. After application of protocol, mean delivered amount of calorie was increased from 33.1% ± 24.2% to 44.8% ± 27.2% and mean delivered amount of protein was increased from 23.8% ± 19.7%to 36.1% ± 23.0%. But the length of stay in ICU was not affected. We discovered that the application of protocol improved nutritional delivery, but it couldn’t affect the length of stay in ICU.

BACKGROUND/OBJECTIVES: Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. SUBJECTS/METHODS: We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. RESULTS: Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). CONCLUSIONS: These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

엔드링을 고려한 농형 유도전동기의 2차원 유한요소해석

하경호,홍정표,김규탁,임태빈,Ha, Gyeong-Ho,Hong, Jeong-Pyo,Kim, Gyu-Tak,Im, Tae-Bin 대한전기학회 1999 전기학회논문지 B Vol.48 No.2

This paper proposes an efficient 2D Finite Element Method(FEM) taking into account the end-ring of three phase squirrel-cage induction motors. The parameters of the squirrel-cage induction motor such as conductivity of secondary conductor have an effect on the characteristics of a motor. Especially, if the characteristic analysis is done without considering the end-ring, the good results can not be obtained. Therefore, we calculated a new resistivity of the secondary conductor including the end-ring's resistance to apply the 2D FEM. Then, the performances of the motors are analyzed by using the new resistivity of secondary conductor which contains the end-ring resistivity. The validity of the proposed method is verified by comparing the numerical results with experimental ones.
