미추마취는 1901년 소개된 경막외마추의 일종으로서 무통분만, 수술후 통증 및 암성통즌의 치료, 항문, 회음부 및 하복부 수술시 성인 또는 소아를 불문하고 현재 널리 이용되고 있는 비교적 안전한 부위마취방법이다. 그러나 가끔 전신중독반응, 태아두부손상, 분만지연, 지주막하마취 및 이에 동반되는 동맥저혈압 등의 합병증과 마취가 전혀 되지 않거든 불확실한 부문적인 마취만 되는 경우도 있을 수 있다. 저자는 치핵제거술은 받기 위한 42세 여자 환자에게 천골열공을 정확하게 찾은 후 19 gauge 바늘로 미추마취를 정확하게 시행했으나 좌측 항문 및 회음부의 외음부신경이 분포하는 지역만 마취가 되고 우측은 전혀 마취가 되지 않은 1예를 경험하였기에 보고하며, 이는 아마도 경막외강의 정중앙에 존재하는 막(plica mediama dorsalis)에 의한 것이라 생각된다.

Locking Compression Plate를 이용한 전위성 쇄골 간부 골절의 수술적 치료

정남식,홍기도,하성식,박성준,강정호,심재천,Chung, Nam-Sik,Hong, Ki-Do,Ha, Sung-Sik,Park, Sung-Joon,Kang, Jung-Ho,Sim, Jae-Cheon 대한정형외과스포츠의학회 2006 대한정형외과스포츠의학회지 Vol.5 No.1

목적: 전위성 쇄골 간부 골절의 치료로 관혈적 정복술 후 LCP를 사용하여 내고정을 시행한 환자를 대상으로 방사선학적, 임상적 결과를 분석하여 전위성 쇄골 간부 골절의 치료에 있어서 LCP의 유용성을 알아보고자 하였다. 대상 및 방법: 2003년 5월부터 2004년 11월까지 본원에서 쇄골 간부 골절에 대해 LCP를 이용한 관혈적 정복, 금속내 고정술을 시행하고 6개월 이상 추시가 가능하였던 26례를 대상으로 하였다. 수술 후 최종 평가는 방사선 결과와 fang s criteria를 이용한 임상적 결과로 분석하였다. 결과: 수술 후 평균 9.3주에 모든 예에서 지연유합 없이 골유합 되었으며 임상적으로 Kangs criteria에 따라 구분한 결과, 우수 이 상이 22례로 나타났다. 특히, 견관절 운동은 상완골 골절이 동반된 두 경우를 제외한 24례에서 2.9주내에 정상 범위로 빠른 회복을 보였다. 합병증으로는 견관절 운동 장애 2례, 수술 절개 부위의 켈로이드 형성 1례였으며 그 이외에 다른 주요 합병증은 없었다. 결론: 전위성 쇄골 간부 골절에서 LCP를 이용한 관혈적 정복 및 금속내 고정술은 기존의 금속판에 비해 수술 후 합병증을 줄이고 효과적인 골유합과 조기 견관절 운동에 도움을 줄 수 있는 좋은 치료 방법 중 하나라고 사료된다. Purpose: To assess the effectiveness of the Locking compression plate (LCP) after open reduction for the treatment of the displaced clavicular shaft fracture, the clinical and radiologic outcome of the patients who were managed with the LCP for internal fixation after open reduction has been analyzed. Materials and Methods: We reviewed 26 cases with a displaced clavicular shaft fracture treated by internal fixation using Locking compression plate after open reduction between May 2003 and November 2004. The patients were followed up for at least six months period, and final postoperative outcome was evaluated using clinical results based on Kang's criteria, radiologic signs of fusion. Results: All fractures united by an average of 9.3 weeks without delayed union and showed fast recovery of motion fraction and shoulder function. In addition,24 cases without the fractures of proximal humerus recovered to normal range of shoulder notion within 2.9 weeks. Clinically, according to Kang's criteria, the outcome was good or better in 22 patients. The complications included shoulder joint dysfunction in two cases and keloid formation in one case, and no other complications were observed. Conclusion: The internal fixation using LCP for the treatment of displaced clavicular shaft fracture is a safe, reliable method of treatment, with few complications, and offers rapid recovery of shoulder joint function and bone union.

성인 Hutchinson-Gilford Progeria Syndrome 의 심혈관계 병변의 관찰

정남식,심원흠,하종원,윤정한,이웅구 대한내과학회 1991 대한내과학회지 Vol.41 No.4

Progeria, or the Hutchinson-Gilford syndrome, is characterized by a growth abnormality and an appearance of premature aging. Cardiovascular change of Hutchinson-Ciilford Progeria syndrome is reported with a brief review of the literature. This 24-year-old male patient was admitted to the hospital because of dyspnea and premature aging appearance. Two-dimensional echocardiography revealed senile aortic valvular calcific stenosis and an enlarged, hypertrophied left ventricle with reduced global systolic function, Pulsed wave Doppler profiles of transmitral inflow revealed a restrictive hemodynamic pattern of the left ventricle. A calcification of the aortic wall and valve was visualized in fluoroscopy, and a grade II/IV of aortic regurgitation demonstrated in an aortogram and LVEDP was 45 mmHg. An 80%, diameter narrowing of the left anterior descending artery and total ostial occlusion of the right coronary artery with good collateral flow from the left circumflex artery were noted in a coronap angiogram. The patient died suddenly 2 weeks after discharge.

The purpose of this study was to apply the instructional strategies for conceptual change prescribed by Posner et al(1982) to the astronomic content domain taught in the elementary and middle school and to analyze the characteristics of students' knowledge revealed in the test before, during and after the instruction. Also, it was to investigate the intercorrelation of cognitive levels, spatial ability and science achievement. The major findings of this study are as follows: 1. Students had a great variety of misconceptions related to the motion of the moon before the instruction, that is, the phases, the names of phases and the cause of changing phases by the moon's orbit about the earth, the moon's appearance and location at the given time, the relative positions of earth, moon and sun during a lunar eclipse, the cause that a full moon is not at the line of node once a month. In the analysis of students' responses concerning the cause of changing phases of the moon and a lunar eclipse, the results indicate that the great majority of students had rote learning rather than meaningful learning in the middle school. 2. Students' reponses during the instruction concerning the changing phases of the moon and the predictive knowledge about the motions of the earth and the moon were analyzed. 1) According to the results of the test given before and after experiment, after discussion, achievement score of the whole of subjects and groups in both preformal and formal cognitive levels appeared to increase linearly. 2) There was no statistically significant differences of achievement scores before and after experiment, after discussion between preformal group and formal group in cognitive levels. 3. Distribution of achievement scores according to the whole of subjects and groups in preformal and formal cognitive levels shows that there was a statistically significant difference between pretest and posttest. 4. Types of conceptual changes concerning the cause of changing phases of the moon that occurred from pretest to posttest were classified as accommodation, incomplete accommodation, assimilation, no change and no model. Six of the seven students starting instruction with alternative frameworks didn't sustain those alternative models throughout instruction. Five of these six students accommodated completely and the last one partially. Seventy-nine percentage of students taking instruction with fragmental models assimilated correct propositions at the end of the instruction. These results suggest that conceptual change model prescribed by Posner et al(1982) has promised the meaningful learning to students taking with fragmental models, especially in cases where students with misconception enter instruction. 5. High correlation between achievement score of simple-recall items and that of written items in pretest and posttest indicates that the higher students got the score in simple-recall items the better they also performed in written items. However, there was no statistically significant differences among cognitive levels, spatial ability and science achievement in the whole of subjects and groups according to the cognitive levels.
