김병수,서재홍,최철원,김열홍,김준석,김정아,손상균,김재석,이경희,이제중,정익주,곽재용,안진석,이정애,박영석 대한조혈모세포이식학회 1999 대한조혈모세포이식학회지 Vol.4 No.1

연구배경: 조혈모세포이식후 신체 및 정신적 장애의 정도가 얼마나 환자의 '삶의 질(QOL)'에 영향을 미치는지에 대하여 외국에서는 연구들이 활발히 진행되고 있다. 그러나 우리나라에서는 조혈모세포이식이 비교적 활발히 시술되고 있음에도 불구하고 이에 대한 연구가 미미한 실정이었다. 연구자 등은 우리 나라에서 조혈모세포이식을 받은 환자들의 QOL은 어떤지를 알아보고자 하는 목적으로 본 연구를 시행하였다. 방법: 본 연구에 참여한 각 기관에서 조혈모세포이식을 받고 주된 치료가 끝난 후 1999년 2월 시점에서 최소 3개월이 지나고 관해상태에서 일상생활을 영위하고 있는 재생불량성 빈혈과 급성 및 만성 백혈병 환자들을 각각 자가 및 동종 조혈모세포이식을 시행받은 조혈모세포이식군(1군)과 항림프구 글로불린, 공고요법 등으로 치료를 끝낸 화학요법군(2군)으로 분류하고 연구자 병원에 내원한 건강한 환자 보호자들로 이루어진 정상대조군(3군)을 선정하여 각각의 QOL을 비교, 분석하였다. QOL의 측정은 EORTC QLQ-C30 문항을 우리나라의 실정에 맞게 번역하여 사용하였다. 결과: 조혈모세포이식군(1군)은 53명, 화학요법군(2군)은 57명, 정상대조군(3군)은 55명 이었고, 성별, 나이, 질환별 분포, 검사시점 등에서의 유의한 차이는 없었다. 각 군간의 QLQ-C30 평균 점수를 비교한 결과, 전반적인 삶의 질에서는 1군이 73.5, 2군이 51.7, 3군이 79.3으로 2군이 1.3군보다 낮았고 역할 및 사회기능은 각각 1군이 64.3/68.9, 2군이 57.6/70.3, 3군이 85.2/85.5로 1,2군이 3군에 비하여 낮았다.(P<0.01). 또한, 오심/구토가 1군은 8.7, 2군은 4.5, 3군은 3.2로 1군이 2, 3군보다 높았으며 통증은 1군은 17.0, 2군은 19.2, 3군은 9.6으로 1,2군이 3군에 비하여 높았다(p〈0.01). 기타 신체, 감정, 인식기능 및 피로에서는 각군간에 유의한 차이를 발견할 수 없었다. 결론: 본 연구에 참여한 조혈모세포이식환자들의 전반적인 삶의 질은 화학요법을 받은 환자들보다 우월하면서 정상인들과 유사하였으나 역할기능 및 사회기증, 통증에서는 화학요법 환자들처럼 정상인들에 비하여 열악하였고 오심/구토는 화학요법 환자들 및 정상인에 비하여 심한 양상을 보였다. 그러므로 본 연구를 바탕으로 하여 국내 실정에 맞는 QOL 측정 방법을 개발하고 조혈모세포이식을 시행받는 환자들의 삶의 질에 관한 연구들이 향후 계속 진행되어야 하리라고 생각된다. Background: It is very important to endow patient with satisactory quality of life (QOL). However, little is known about QOL after hematopoietic stem cell transplantation (HSCT) in Korea. In this study we tried to measure QOL in the patients treated with HSCT and compare QOL scores with those of patients treated with usual chemotherapy and normal populations. Methods: The QOL evaluation was performed with EORTC QLQ-C30 questionnaires interpreted to Korean language. The study populations were consisted with 53 patients treated with HSCT (Group 1), 55 patients treated with usual chemotherapy (Group 2), and 55 normal populations (Group 3). The QLQ-30 scores of each group were evaluated and compaired with x² test. Results: Global quality of in group 1, 3 (score: 73.5, 79.3, respectively) were higher than that (score: 51.7) of group 2. Role and social function were lower in group 1, 2 (score: 64.3/68.9, 57.6/70.3, respectively) than those (score: 85.2/85.5) of group 3. The degree of nausea and vomiting was more severe in group 1 (score: 8.7) than those of group 2, 3 (score: 4.5, 3.2 respectively). Pain scores of group 1, 2 (score: 17.0, 19.2, respectively) were more higher than that of group 3 (score: 9.6) In other parameters of QLQ-C30, there was no significant difference between each groups. Conclusion: Our perliminary result may suggest that HSCT is not necessarily associated with deterioration of QOL. This underlines the necessity of undertaking perospective studies using reliable and well-validate methods for measuring QOL

Agranulocytosis, one of the major side effects of antithyroid a gents, probably occurs in less than 0.25% of cases treated with antithyroid agents. It usually occurs within the first several weeks or months after the initiation of therapy, when drug dosage is higher. Most reported cases of agranulocytosis have occurred during the first 3 months of therapy. We describe here a rare case that did not experience the side effect for 6 years of antithyroid agent treatment but presented with agranulocytosis in one month after re-exposure. It suggests that the major side effect such as agranulocytosis can occur in patients who had undergone prior uneventful antithyroid drug therapy.

Background/Aims: The major morbidity after adult living donor liver transplantation (ALDLT) is due to biliary complications. The aim of the present study is to evaluate 1) the kinds of biliary complications and their incidence, 2) the risk factors of biliary stricture and 3) the clinical outcomes of management. Methods: Between January 2000 and December 2006, 259 adult patients underwent ALDLT at Seoul National University Hospital. Among 259 recipients, 20 patients died during the postoperative period. We retrospectively analyzed the remaining 239 patients. Results: The mean follow-up period was 40 months (range, 7-90 months), and the graft failure rate was 3%. The 1-year survival rate was 91%. The main causes of death were hepatocellular careinoma recurrence (65%), acute or chronic rejection (10%), sepsis (10%) and HCV reactivation (5%). The overall incidence of biliary complications was 28.9% for biliary stricture, 6.2% for bile leakage, 1.6% for bile duct stone and 0.8% for biliary cast. On multivariate analysis, the risk factors of biliary stricture were multiple bile duct anastomosis (OR 3.25, CI 1.2-8.7, p=0.02), bile leakage (OR 28.1, CI 3.3-238.1, p-0.02) and hepatic artery stenosis (OR 9.7, CI 2.3-41.4, p=0.002). All strictures were initially treated nonsurgically (endoscopic cholangioplasty, n=27; percutaneous cholangioplasty, n=41; and observation, n=1). However, 6 patients ultimately required biliary reconstruction. The patients with bile leakage were treated with endoscopic nasobiliary drainage (n=3), percutancous transbiliary drainage (n=11) or biliary reconstruction (n=1). Biliary casts and stones that developed after ALDLT were cured with endoscopic or percutaneous removal. Conclusions: The most common biliary complication after ALDLT was biliary stricture. Hepatic artery stenosis, multiple bile duct anastomosis and bile leakage were significantly associated with biliary stricture. Biliary complications can be successfully managed with nonsurgical methods.

Seo, Jeong Kyun,Kim, Su Hyun,Lee, Sang Hyub,Park, Joo Kyung,Woo, Sang Myung,Jeong, Ji Bong,Hwang, Jin-Hyeok,Ryu, Ji Kon,Kim, Jin-Wook,Jeong, Sook-Hyang,Kim, Yong-Tae,Yoon, Yong Bum,Lee, Kuhn Uk,Kim, S Lippincott Williams Wilkins, Inc. 2010 European journal of gastroenterology & hepatology Vol.22 No.8

BACKGROUND: Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are often confused with other intrahepatic cystic diseases. AIMS: The aims of this study were to investigate predictive factors of biliary cystic tumor (BCT) and clinical characteristic of BCAC. METHODS: We retrospectively reviewed preoperative diagnoses, overall characteristics and postoperative outcome of 20 BCTs and 19 cystadenoma-mimicking simple cysts that were pathologically confirmed. RESULTS: Comparing with atypical simple cysts, symptoms, left-lobe cyst, thick wall, septation, mural nodule, bile duct dilatation and an increase of serum alkaline phosphatase were associated with BCTs. However, on multivariate analysis, mural nodule, left-lobe cyst, and an increase of serum alkaline phosphatase were significantly frequent in BCTs with odds ratios of 75.5, 13.8, and 33.0, respectively. Among the 20 BCTs, seven BCACs were diagnosed. The characteristics of BCACs were mural nodule (P<0.01), intrahepatic cyst debris (P<0.01), and bile duct dilation (P=0.04). Cystic fluid analysis provided no significant differences between BCT and simple cyst. After fine needle aspiration cytology of BCTs, all except one BCAC with atypical cell showed nonspecific findings. After complete surgical excision (97.4% of patients), only one patient with BCAC had recurrence during 29 months of follow-up period. CONCLUSION: In hepatic cysts with mural nodule, left-lobe cyst or increment of serum alkaline phosphatase seem to be indicative of BCTs in the diagnosis of suspicious hepatic cyst. Intracystic debris, bile duct dilation, and mural nodule may be suggestive clinical features of malignancy in BCTs.

본 연구에서는 최근 친환경 재료에 대한 의식의 변화로 인한 목재의 실내 사용 증가에 따른 화재 위험성을 절감하기 위하여 붕소-인계, 암모늄계 화학종을 혼합하여 제조한 방염액을 처리한 방염 목재의 방염 성능 및 연소 특성에 대하여 평가하였다. 방염액은 친환경성과 목재 표면 처리 시 발생할 수 있는 백화 현상을 고려하여 붕소-인계 성분을 조절하고 방염 성능을 향상하기 위하여 암모늄계 화학종을 첨가하여 혼합 제조하였다. 본 연구에서 처리된 방염 목재는 국내에서 실시되고 있는 방염성능평가기준(KOFEIS 1001)에 의거하여 성능 평가를 실시하였으며, 연소 시 방출되는 가스유해성을 확인하기 위해 KS F 2271 기준을 적용하였다. 방염성능평가 시험 결과, 상용 방염액 2종과 비교하였을 때 자체 개발된 방염액 FRCs의 성능이 유사하게 나타났으며, 무처리 시험편에 비해 FRCs를 처리한 시험편의 탄화면적은 약 80%, 탄화길이는 약 50%로 감소된 것으로 확인하였다. 방염액 3종을 비교한 가스유해성 평가의 결과에서는 상용 방염액 2종의 경우 각각 7분 24초, 7분 54초로 확인되어 성능 기준을 만족하지 못하였으나, FRCs 처리 시험편의 경우 9분 44초의 결과를 나타내어 규격을 만족하였다. 본 연구는 목재 및 목질재료용 방염액의 적정 혼합비율을 개발하여 향후 건물 실내 적용 시 화재 확산을 억제하고 유해가스 성분 방출을 감소시키는 연구를 진행하는 데 목적이 있다. This study carried out analysis of the flame-retardant performance and hazards in gas products according to the flame retardant performance standard of KOEFIS 1001 and the test procedure of KS F 2271 for incombustibility internal finish material and element of buildings (KS F 2271). Flame retardant chemical composites (FRCs) was prepared by adding boron-phosphorus and nitrogen element content. When manufacturing FRCs, environmentally friendliness and whiteness on the surface of wood as well as the content ratio of the boron-phosphorus chemical compounds were considered. As a result of flame retardant performance test, the performance of FRCs was similar in comparison with the two flame retardant solutions. Also, the carbonization area of the FRCs reated specimens was reduced to about 80%, and carbonization length was reduced to about 50% in comparison with untreated specimens. The results of the gas hazard test comparing the three flame retardants showed that two commercial flame retardant solutions were 7 minutes 24 seconds and 7 minutes 54 seconds, respectively, however, the FRCs treated specimens showed a result of 9 minutes and 44 seconds. And the result was satisfied with the limits defined in the specification. The purpose of this study is to develop appropriate mixing ratio of flame-retardant solution for wood and wood-based material of building applications, and to suppress fire spread and to reduce the emission of harmful gas components.

  In mobile ad-hoc networks(MANETs), nodes are mobile and network topology changes very frequently. The mobility of nodes does affect the system performance. There has been considerable attention on the mobility models, however, most work is confined to the simulation or test-bed. In this paper, we propose an analytical method to evaluate the performances of MANETs such as the average radio range dwell time of mobile nodes, link holding time, and transmission failure probability considering the node"s mobility. In the proposed model, MANETs consist of the multi-hop and multicasting routing paths. A simulation is done to validate our proposed analytical model.
