A 37-year-old woman who had undergone coronary artery bypass grafting (CABG) surgery for left main and right coronary ostial lesions 2 years prior presented with angina and transient visual dimness. Computed tomography angiography showed a patent left internal mammary artery (LIMA) bypass graft and concentric narrowing with perivascular thickening around the arch vessels. The patient was diagnosed with Takayasu arteritis with coronary subclavian steal syndrome (CSSS). Thoracic angiography revealed severe stenosis of the left proximal subclavian artery (SCA) and reverse flow from the coronary artery to the distal left SCA via the LIMA graft. Successful percutaneous stenting of the left SCA was performed together with stenting of the right common carotid artery (CCA). The patient’s symptoms were completely resolved. This case is informative since it shows that Takayasu arteritis can manifest as angina due to coronary ostial lesions and then can involve arch vessels, which can lead to CSSS in patients with CABG.

N/A Objective: Restenosis after successful PTCA remains the main limitation of this technique. Restenosis is a response to injury of the vessel wall, platelet aggregation, thrombus formation, liberation of growth factors, cellular hyperplasia involving predominantly smooth muscle proliferation and migration, and intercellular matrix formation. The identification of risk factors for restenosis could help to prevent and reduce the impact of this phenomenon. We undertook this study to evaluate retrospectively the association between risk factors and restenosis after PTCA Methods: We studied 123 patients and 174 lesions that underwent successful P1YA and the follow-up period (from PTCA to follow-up angiography) was 8.2±5.8 months in all patients. They were divided into two groups according to the restenosis. Clinical feature, lesional feature, PTCA procedural feature, and other risk factors were compared. Restenosis was defined as the cutoff paint of >50% in diameter stenosis at angiographic follow-up. Results: 1) Restenosis was found in 68 lesions after successful PTCA (39.1%), 2) Clinical features of restenosis group are similar to no restenosis group 3) Thrombus (p=0,002), total occlusion (p=0.001), severity of stenosis in the initial lesion (p=0.013) and residual stenosis (p=0.001) were found to be independently associated with restenosis, whereas other lesional characteristics were not. 4) Balloon inflation duration (p=0.017) and dissection (p=0.002) were found to be independently associated with restenosis, whereas other procedural characteristics were not. Conclusion: Thrombus, total occlusioo, dissection, severity of stenosis in the initial lesion, balloon inflation time, residual stenosis were found to be associated with restenosis after PTCA in our study.

N/A Background: Little has been known about the incidence, the relationship with H. pylori infection and the prognosis of the multiple gastric polyposis. Recently, it was suggested that the eradication of H. pylori infection led the disappearance of the gastric polyps associated with H. pylori. We carried out a prospective study to determine the effect of H. pylori eradication on multiple gastric polyposis associated with H, pylori. Methods-From July 1997 through August 2000, 13 patients who had multiple gastric polyposis on upper gastrointestinal endoscopy were recruited for this study. After eradication of H. pylori, we performed follow-up endoscopy at 2-3 months and 5-6 months later. Results : The topographical distributions of gastric polyps were as following : antrum only in 7 cases, antrum and lower body in 4 cases, antrum and fundus area in 1 case, and entire stomach in 1 cases, respectively. The histopathological findings were as following : 13 cases showed chronic active gastritis, 2 cases with hyperplastic polyps, and 1 case with adenomatous polyps. After eradication of H. pylori infection, regression of multiple gastric polyps occurred in 7 cases (53.8%). In 7 cases with regression, regression was observed in 5 cases with chronic active gastritis alone, 1 case with hyperplastic polyps, and 1 case with adenomatous polyps. The re-biopsy specimens in 7 cases with regression revealed that the grade of inflammation decreased from 2.2 to 1.5 by the histological index of the updated Sydney system. Conclusion : With these results, we may conclude that the development of multiple gastric polyposis might be closely related with chronic H. pylori infection, and the eradication of H. pylori could lead to the regression of polyposis.

본 논문에서는 3축 가속도 센서를 이용하여 사람이 보행 시 발생하는 센서 데이터를 획득하여 실시간 걸음 수 검출이 가능한 웨어러블 디바이스를 개발하였다. 피험자 59명을 대상으로 트레드밀에서 Actical 과 본 연구에서 개발된 디바이스를 착용 후 36분 동안 테스트 프로토콜에 따라 느리게 걷기, 걷기, 빠르게 걷기, 천천히 뛰기, 뛰기, 빠르게 뛰기 등의 다양한 걸음속력에서 테스트를 진행하였다. 3축 가속도 센서의 X, Y, Z축 출력 값을 하나의 대표 값으로 처리하는 신호벡터크기(Signal Vector Magnitude:SVM)를 사용하였다. 또한 정확한 걸음 수를 검출하기 위해 휴리스틱 알고리즘(Heuristic Algorithm:HA)을 제안하고 적응적인 임계값 알고리즘(Adaptive Threshold Algorithm:ATA), 적응적인 잠금 구간 알고리즘(Adaptive Locking Period Algorithm:ALPA)을 제안한다. 실험결과 제안하는 알고리즘의 걸음 수 인식률은 97.34%로 Actical의 인식률(91.74%)보다 5.6%향상 되었다. We have developed a wearable device that can convert sensor data into real-time step counts. Sensor data on gait were acquired using a triaxial accelerometer. A test was performed according to a test protocol for different walking speeds, e.g., slow walking, walking, fast walking, slow running, running, and fast running. Each test was carried out for 36 min on a treadmill with the participant wearing an Actical device, and the device developed in this study. The signal vector magnitude (SVM) was used to process the X, Y, and Z values output by the triaxial accelerometer into one representative value. In addition, for accurate step-count detection, we used three algorithms: an heuristic algorithm (HA), the adaptive threshold algorithm (ATA), and the adaptive locking period algorithm (ALPA). The recognition rate of our algorithm was 97.34% better than that of the Actical device(91.74%) by 5.6%.

연구목적: 신경정신과에 자문 의뢰된 사례 중 섬망상태를 주 증상으로 한 환자들을 대상으로 자문의사와 의뢰의사간의 진단 일치율 및 정신과 권고사항에 대한 반영도를 조사하여 자문시 상호 협조정도를 알아보고 치료 반영도에 영향을 미치는 요인을 밝히려 하였다. 방법: 1995년 7월 1일부터 1997년 12월 31일 사이에 한양대학교 구리병원에 입원하여 신경정신과에 자문 의뢰되었던 583명 중 54명의 섬망환자를 대상으로 하였다. 대상자의 자문요청서와 과거입원기록을 통해서 환자들의 인적사항, 입원진단명, 증상, 의뢰 전 처방, 정신과 처방, 의뢰 후 처방, 섬망에 대해 의뢰의사가 내린 진단과 자문의사의 진단 등에 대한 정보를 얻었다. 권고사항에 대한 반영도는 완전 반영, 부분 반영, 비반영으로 나누어 이중 완전 반영과 부분 반영을 반영한 것으로 평가하였다 의뢰한 과를 각 과별 그리고 내과계와 외과계로 나누어 각각의 반영도를 비교하였다. 결과: 섬망상태의 원인에 대한 진단 일치율은 자문과의 진단 기준으로 보면 원인이 기질성 뇌 증후군 (organic brain syndrome)인 경우가 가장 높았고 (85.7%) 전반적인 의학적 상태(general medical condition)의 경우가 가장 낮았다 (0%). 반영도는 의뢰과별로 유의한 차이가 없었으며, 내과계와 외과계간에도 유의한 차이가 없었다. 반영도에 영향을 미치는 중상을 비교한 결과 충동적 공격적 행동이 동반된 경우에 반영도가 73.5%이고, 행동변화가 동반되지 않은 경우가 40.0%여서 행동상의 문제가 동반되었을 때 정선과 의견에 대한 반영도가 통계적으로 유의하게 높았다. 수면장애가 동반된 경우에도 반영도가 높았는데 행동변화와 수연장애의 두 증상을 하나의 변인으로 비교한 결과, 두 증상이 모두 있는 경우는 반영도가 80.0%, 하나의 증상만 있거나 모두 없는 경우 반영도가 44.8%여서 유의한 차이가 있었다. 의뢰과에서 평가가 용이하지 않은 증상인 의식상태, 지남력상태, 환각의 유무는 반영도와 통계적 유의성이 없었다. 결론: 섬망의 원인에 대한 진단 일치율은 병변의 확인이 용이한 기질성 뇌 증후군의 경우가 가장 높았고 권고사항에 대한 반영도에 영향을 주는 요인은 행동변화와 수면장애의 증상이 나타나는 경우였다. Objectives : The author investigated the rate of diagnostic agreement between consultants and consultees and concordance ratings on the consultees' recommendation to examine the interactive collaborativeness and find the factors that influence the reflectiveness on treatment. Methods : The subjects were 54 patients with delirium selected from 583 cases referred from other departments who were admitted to Hanyang University Kuri Hospital from July 1, 1995 to Dec. 31, 1997. The information on demographic data, diagnostic impression, symptoms, management before consultation, psychiatric recommendation, management after consultation, diagnoses at the referring departments and the psychiatric department on delirium was obtained by medical records and consultation papers retrospectively. The reflectiveness of the psychiatric recommendation was divided into complete concordance, partial concordance, and nonconcordance and among them the complete and partial concordance were considered for concordance. The reflectiveness was compared among all the departments and between medical unit and surgery unit. Results: The rate of diagnostic agreement on the cause of delirium was highest(85.7%) in organic brain syndrome and lowest in general medical condition(0%). There was no statistically significant differences between medical unit and surgery unit. Neither differences were there among all the departments. In comparing symptoms affecting the reflectiveness, it was 73.5% in impulsive and aggressive behavioral changes, whereas 40.0% in behavioral changes. Reflectiveness of psychiatric recommendation showed higher scores in the case of behavioral changes. The cases of sleep problem showed higher scores of reflectiveness. When these two symptoms of behavioral change and sleep problem were compared as one factor, the results suggested that there were significant differences. The cases with both two symptoms showed 80% in reflectiveness, and the cases with only one symptom or no symptoms showed 44.8% in reflectiveness. There were no statistical significances between concordance ratings and symptoms such as disturbance of consciousness, disorientation, and hallucination that cannot be easily evaluated at the referring departments. Conclusions : The rate of diagnostic agreement on the cause of delirium was highest in the case of organic brain syndrome in which lesions can be easily recognized. The factors that influence the reflectiveness of psychiatric recommendation were behavior changes and sleep disorders in the symptoms of evaluated cases.

Training for asthma patients by professionals has been highly emphasized for patients' self-management. In the present study, three standardized training sessions targeting hospital pharmacists were performed. On the basis of the number of training sessions taken, a non-educated group (CG), an once-educated group (NG), and a twice more-educated group (IG) were allocated. The most frequent errors of using an inhalant were shaking before the use in MDI while taking breathe out before inhaling in the case of DPI, and the total average number of errors were the biggest for CG and the smallest in IG. On comparison in the number of the four symptoms of asthma according to the level of seriousness, it was revealed that the total average number was the biggest in CG and the smallest in IG. In the level of awareness regarding the contents of training for patients, patients over 50 tended to answer that they were aware of education contents, and particularly in mouth rinsing and the use before/after a meal, significant similarity was examined. Regular asthma patient training performed by hospital pharmacists appeared to reduce errors in the inhaler usage, increase the quality of life of an patient, and help a patient remember the contents of the training. Especially among patients over 50, it was found to be more effective and retraining of more than two sessions was requisite.
