연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

404 nurses and nurse-aids rated their experiences of 45 symptoms(Moos' Menstrual Distress Questionnaire) of the menstrual, premenstrual and intermenstrual phase on a 4 point scale separately. The 45 symptoms were inter-related and factor analyzed separately for each phase. six common clusters of symptoms emerged from 3 phases, which were labeled concentration, motor tension, pain, pleasurable affect, autonomic reactions and water retention. Four clusters of symptoms emerged from premenstrual phase. These clusters were labeled instabillity, withdrwal reactions, depression and headache. The factor named unpleasurable affect emerged from intermenstrual and menstrual phase. Above findings were differed from the results of Moos' study in which eight basically replicated clusters of symptoms emerged from three phases. Through discussion of validity of this scale, and differences between results of Moos' and this study, we came to the conclusion that sampling of subjects, prospective longitudinal symptoms reporting, amount of variance in a symptom over the course of menstrual cycle and proper choice of factor analysis method would be salient variables to construct valid scale for measuring menstrual cycle symptoms.

This study is to investigate the adsorption capacity of the wastes obtained from three different depth and quality in Nanji landfill site. Nanji landfill site was the biggest site until Kimpo sanitary landfill site emerged in Seoul Metropolitan Area. It had been landfilled for 14 years from the year of 1978 to 1992. Continuous experiments were performed employing synthetic heavy metal-bearing solution and the modified column apparatus of ASTM standards. Each waste sample was analyzed to find out the physicochemical properties such as moisture contents, ignition ashes and combustible components in wet and dry bases. The quantitative analysis of metals was determined by use of ICP (inductively Coupled Plasma Emission Spectroscopy). From the study, following conclusions were obtained : 1) Physicochemical properties of soils in landfill site were moisture contents 20.8 - 52.4 %, ignition ashes 44.6 - 75.4 % and combustible components 2.5 - 3.7%, respectively. 2) Adsorptivity of soils was sely related to the organic matter decomposition and the formation of humic substances in the land-disposed wastes. 3) After 25 days, breakthrough point occurred in any soil column except that for soil type 3.

Objectives : To investigate the nature of emotional responsiveness in norma) adults, we exam the emotional responses to emotional pictures in an evaluative space defined by arousal and valence. Methods : Subjects were instructed to rate the arousal and valence that they experienced from the presentation of one of two sets of 60 emotional pictures. These two picture sets were comprised of 107 pictures : 101 selected from Intetnational Affective Pictures System and six pictures from our own collection. According to "evaluative space model", the authors set an evaluative space defined by the arousal scores as independent variable and the valence scores as dependent variable. In this evaluative space, one-hundred-and-seven pairs of coordinates representing respective emotional pictures were plotted. With regression analyses, the steepness of the regression lines on the plots with positive emotional responsiveness (n=51) and those with negative emotional responsiveness (n=56) were compared. Results : In the evaluative space, the regression line of negative emotional responsiveness was significantly different from that of positive responsiveness. The slope of negative responsiviveness was significantly steeper than that of positive responsiveness. At a low arousal level, the absolute valence of a positive stimuli was larger than that of a negative picture. Conclusion : This finding indicates that the function of the negative affective responsiveness might be different from that of the positive responsitiveness. IAPS also seems applicable to Korean subjects.

Background: This study evaluated the efficacy of administering Donepezil(Aricept^(?)) for improving cognitive function, activities of daily living, and quality of life in patients with post-stroke dementia. Methods: Patients(n=99; mean age, 69.89 years; 48.5% men) with post-stroke dementia, according to criteria of the DSM-IV and MRI, were treated with donepezil 5mg/day or 10mg/day during 24 weeks. They were examined using Mini-mental Status Examination(MMSE), Chinical Dementia Rating(CDR), Barthel Activities of daily living(B-ADL), Instrumental Activities of daily living(I-ADL), Short Form 36 Health Survey-Korean(SF-36-K), and Geriatric Depression Scale(GDS) at before treatment and 24 weeks after treatment. Results: The 97 patients completed the trial. At 24 weeks, they showed significant improvement in MMSE(p<0.001), CDR(p<0.001), B-ADL(p=0.002), I-ADL(p<0.001), and SF-36-K(p=0.003) except GDS(p=0.288). Donepezil was well tolerated. There was no withdrawal due to adverse events. Conclusion: This results demonstrate that donepezil was beneficial in improving the cognitive function, activities of daily living, and quality of life in patients with post-stroke dementia and was well toleraetd.
