Background : Bleeding after endoscopic procedure of the stomach carries an increased risk of morbidity and mortality. In case of oozing hemorrhage, not in active hemorrhage, powdered sodium alginate may play a role in control of bleeding with convenience. Therefore, we evaluated the clinical effect and efficacy of sodium alginate powder in upper G-Ⅰ bleeding. Methods : Forty-five patients who had upper G-Ⅰ bleeding after endoscopic procedure were enrolled in this study. Twenty-five patients of them were managed by the application of powder preparation of Sodium alginate(ALTO). The others were observed without treatment. The next day, we performed endoscopy in all patients to ascertain the hemostasis. Results : Of 25 patients managed with Sodium alginate, only two patients(8%) had bleeding (hemostatic rate : 92%), On the other hand, of 20 patients who did not receive any treatment, 3 patient(15%) had bleeding (hemostatic rate : 85%). There was no statistical difference between the two groups(p>0.05). Using other endoscopic procedure, We successfully treated the patient who continued to bleed. Conclusion : We evaluated the effect of the spary of sodium alginate on oozing hemorrhage. Although there was no statistical significance in our study, it seems that the spray of sodium alginate may be a useful method for the prevention of bleeding after endoscopic procedure.

자궁내막에 발생한 점막 연관 림프조직 (MALT) 림프종 1예

Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.

최근 학교폭력, 청소년 성매매, 마약, 가출 등 청소년에 의한 범죄와 비행이날로 증가하고 있다.1) 이러한 상황은 자라나는 청소년들에게 급변하는 사회환경에 적절하게 대응할 수 있는 올바른 가치관과 도덕성 함양기능을 제대로 수행하지 못한 결과가 아닌가 생각한다. 최근 일각에서 청소년을 대상으로 한 인성교육의 중요성이 부각되고 있는 것은 다행스런 점이 있다. 이 논문은 Kohlberg(1976)의 도덕발달이론을 논거로 하여 비행청소년과 정상청소년간의 도덕적 추론능력의 차이를 비교한 연구이다. 그에 의하면 도덕의 발달단계에 따라 도덕적 지향의 형태가 달라지고, 도덕적 판단력의 형성에 있어서의 차이는 도덕적 행위나 비도덕적 행위에 관련이 있다고 한다. 논문에서 비행청소년의 도덕적 추론능력을 검증한 결과, 비행청소년은 전인습적 도덕성에 속하는 1, 2단계에 속하는 것으로 밝혀졌다. 또 이를 정상청소년을 준거집단으로 한 비교분석을 해 본 결과, 전인습적 도덕성에 속하는 1단계에서 유의한 차이가 있음이 밝혀졌으며, 이 외에 인습적 도덕성에 속하는 대인간의 조화와 순종의 단계에서도 유의한 차이가 발견되었다. 3단계인 대인간의 조화와 순종단계에서도 정상청소년과 유의한 차이가 있다는 의미는 비행청소년이 대인관계의 기술면에서 부족하다는 것을 나타낸다. 그 외의 단계에서는 비행청소년과 정상 청소년 간에 유의한 차이가 발견되지 않았지만 정상청소년은 콜버그의 도덕적 발달단계에서 상위단계에서도 비교적 높은 점수를 나타내고 있음을 볼 수 있다. 이러한 연구결과는 청소년을 대상으로 도덕성 함양교육 내지 인성교육이 중요함을 시사하고 있다. The purpose of the present study were to compare of moral development level between delinquent adolescences and normal adolescences, and the helpful date in understanding and guiding the delinquent adolescences. Based on the previous studies and Kohlberg's Moral development theory, it was hypothesized that there are difference of total and subfactoric moral development degree between delinquent adolescences and normal adolescences. Subject for the study were 298 boys(middle school:48/high school: 120/delinquent : 130) in Dae-Jeon. They were examine in Kohlberg's Moral development scale which rewrited by Kim Sang Gyun. Statistical methods applied for the present study was mean, standard deviation, and t-test. The statistical computation were done by SPSS 8.0 computer programs. Following conclusions were derived from the results and the discussion. 1. Hypothesis 1 was accepted. Delinquent adolescences had high score on moral development's means compare with normal adolescences. 2. Hypothesis 2 was partially accepted. Delinquent adolescences showed lower "stage 1, stage 2, stage 3" than normal adolescences. However, there were no significant differences of " stage 4, stage 5 and stage 6"

Background : Since highly active antiretroviral therapy has lengthened the life span of individuals infected with human immunodeficiency virus (HIV), the importance of malignancy associated with HIV has been increased. The relative frequencies of malignancies in HIV infected patients may vary in different race and region. The aim of this study is to determine the prevalence and characteristics of malignancies in patients with HIV infection in South Korea. Materials and Methods : To identify HIV patients with malignancy, we reviewed the electronic database of pathological reports for all HIV-infected patients seen from January 1986 to December 2005 at the Seoul National University Hospital. We retrospectively reviewed the medical records of them. Results : Among 850 patients infected with HIV, 33 episodes of malignant diseases were diagnosed in 32 patients (3.76%). Thirty were males, and median age was 46 years (range 29-70). At the time of the diagnosis of malignancy, median CD4^(+) lymphocytes count was 100/uL (range 5-620) and in 27 (82%) patients, CD4^(+) lymphocytes count were less than 200/uL. For 13 patients (40%), malignancy was initial presentation of HIV infection. Excluding patients initially diagnosed as malignancy, median follow-up duration from the first visit to diagnosis of malignancy was 36 months (range 3-96). Non-Hodgkin's lymphoma was the most frequent malignancy (13 patients), followed by Kaposi's sarcoma (7), Hodgkin‘s disease (3), acute myeloid leukemia (1), and other solid cancer (9) including one case of anal cancer associated with human papillomavirus. Among 13 patients with non- Hodgkin's lymphoma, 4(31%) achieved the complete remission after chemotherapy and/or radiation therapy, and had been followed without evidence of recurrence. Conclusion : Malignancy was diagnosed in 3.76% of patients infected with HIV. Non-Hodgkin‘s lymphoma is the most prevalent malignancy in HIV patients in South Korea. 목적 : 효과적인 항레트로바이러스 다제요법이 도입됨에 따라, HIV 감염환자들의 수명이 증가되었고, 이에 따라 HIV 감염환자에서 악성종양의 중요성 또한 증가하고 있다. 본 연구의 목적은 우리나라 HIV 감염환자에서 악성종양의 유병률과 호발하는 악성종양의 특성을 밝히는 것이다. 재료 및 방법 : 1986년부터 2005년까지 서울대학교병원에서 치료를 받은 HIV 감염환자의 의무기록을 후향적으로 분석하였고, 병리학적 검사 결과를 검토하여 악성종양이 진단된 환자들을 대상으로 연구를 시행하였다. 결과 : 총 850명의 환자 중, 32명(3.76%)에서 33예의 악성종양이 진단되어, 악성종양의 발병률은 1,000인년 당13.0명(95% 신뢰구간: 8.6∼17.4명)이었다. 그 중 남자는 30명이었고, 악성종양 진단 당시 연령의 중간값은 46 (29-70)세이었다. 악성종양 진단받을 당시, CD4 림프구 수의 중간값은 lOO/uL (5-620 uL) 이었고, CD4 림프구수가 200/ uL 미만인 환자가 27명(82%)이었다. 악성종양에 대한 검사 도중에 HIV 감염사실이 밝혀진 환자가 13명(40%)이었다. HIV를 진단 받은 후 악성종양이 발병한 환자들에서, HIV 진단 후 악성종양의 발병까지는 평균 36개월(3-96개월)이 걸렸다. 13명의 HIV 감염 환자에서 진단된 비호지킨림프종이 가장 흔한 악성종양이었고, 이외에 카포시육종이 7명, 호지킨병이 3명, HPV와 연관된 항문암이 1명의 HIV 환자에서 진단되었다. 그 밖에 급성백혈병, 방광암, 췌장장, 폐암, 진행성위암, 갑상선암, 간세포암, 후두암이 각각 1예씩 진단되었다. 비호지킨림프종이 진단된13명 환자 중, 4명(31%)은 항암치료 및 방사선치료를 받아 완전관해가 되었고, 현재 재발의 증거 없이 외래에서 경과 관찰 중이다. 결론 : 우리나라 HIV 감염환자에서 악성종양의 유병률은 3.76%이었고, 비호지킨림프종이 가장 흔한 악성종양이었다.

( Yu Ho Lee ),( Yang-gyun Kim ),( Sang-ho Lee ),( Ju-young Moon ),( Kyung-hwan Jeong ),( Tae-won Lee ),( Chun-gyoo Ihm ) 대한신장학회 2014 Kidney Research and Clinical Practice Vol.33 No.3

Background: Urinary kidney injury molecule-1 (KIM-1) is an early and sensitivebiomarker of acute kidney injury, but it is unclear if it is a biomarker of chronicglomerulonephritis. We evaluated whether urinary KIM-1 levels in patients withimmunoglobulin A (IgA) nephropathy can be a marker to reflect clinicopathologicalseverity and predict the prognosis. Methods: We measured urinary KIM-1 levels in 40 patients (15 males; mean age36.6712.9 years) with IgA nephropathy and 10 healthy people (5 males; mean age37.379.6 years) as controls. The correlation of urinary KIM-1 levels with patients’clinical parameters, histological grades, and follow-up data were analyzed using themodified H. S. Lee grading system and tubulointerstitial change scores. Results: Urinary KIM-1 levels were higher in patients with IgA nephropathy thanhealthy controls (P¼0.001). Univariate and multivariate regression analyses showedthat urinary KIM-1 levels had a direct correlation with H. S. Lee grade andtubulointerstitial inflammation (P¼0.004 and P¼0.011, respectively). Conclusion: In patients with IgA nephropathy, urinary KIM-1 has a significantcorrelation with histopathologic severity.
