Castlemans disease is a rare, benign disorder of the lymphoid tissue, and refers ta a distinctive type of giant lymphoid hyperplasia that forms tumor-like masses in lymph nodes and, occasionally, in extranodal sites. Although the mediastinum is its the most common location, it also occurs, albeit rare, in other areas of the body, where lymph nodes are normally found. It is difficult to differentiate between Castlernans disease and other malignant lesions preoperatively. We report a case of a hyaline-vascular variant of Castlemans disease presenting as a solitary retroperitoneal mass in a 39 year old female patient. We also present the MR features, together with conventional radiologic imagings, which made it possible to diagnose Castlemans disease preoperatively, although the mass of the patient was in an unusual location, This report may provide information on differentiation between primary retroperitoneal malignancies and Castlemans disease.

N/A We experienced a case of primary sclerosing cholangitis(PSC) in a 40-year-old female who complained of jaundice and pruritus. Marked elevation of serum alkaline phophatase level, typical beaded appearance and pruned-tree appearance on endoscopic retrograde cholangiography, together with a finding of chronic obliterative fibrosing cholangitis on sono-guided gun biopsy specimen of the liver led to a confirmative diagnosis of PSC. The patient responded to ursodeoxycholic acid (UDCA), but was reluctant to treatment and died of hepatic failure 7 months later. PSC is a very rare disease in Korea. So far, only 5 cases including our present case have been reported in the Korean literature. Male-to-female ratio was 2:3 and the median age was 40(27-80 years old). Ulcerative colitis was associated in one case. Four cases involved both intra, and extrahepatic bile ducts and one case was reported to be confined in the intrahepatic bile ducts. Fatality was in 3 cases, 20 days, 36 days, and 7 months after the initial presentaion, respectively. The causes of death were acute cholangitis and sepsis in two, and hepatic failure in one. We herein report a case of PSC and clinical charateristics of the reported cases in Korea, and review the literature with an emphasis on UDCA treatment in PSC.

본 논문은 정밀한 메모리 워크로드 분석을 위해 리눅스 기반의 커널 수준에서 프로세스의 메모리 관리 구조체에 직접 접근하는 방법을 이 용하여 고속으로 커널 데이터를 수집하는 기법을 제안한다. 기존의 분석기들은 데이터 수집 속도가 느리고 제공되는 데이터의 제한으로 인하여 확장성이 부족하다. 제안 기법은 메모리 관리 구조체 내의 프로세스 메모리정보, 페이지 테이블, 페이지 구조체를 직접 수집하는 방법을 이용하 여 기존의 기법 보다 빠르게 커널 데이터를 수집하며, 사용자가 원하는 데이터를 선택하여 수집할 수 있다. 제안 기법을 통해 실제 실행 중인 프로세스의 메모리 관리 데이터를 수집하고 메모리 워크로드에 대한 분석을 수행하였다. This paper proposes high speed kernel data collection method for analysis of memory workload, using technique of direct access to process`s memory management structure. The conventional analysis tools have a slower data collection speed and they are lack of scalability due to collection only formalized memory information. The proposed method collects kernel data much faster than the conventional methods using technique of direct collect to process`s memory information, page table, page structure in the memory management structure, and it can collect data which user wanted. We collect memory management data of the running process, and analyze its memory workload.
간경변과 임신 : 증례 보고 및 국내 문헌 고찰 A case report and a review of the reported cases in Korea

간경변 환자에서의 임신은 비교적 드문데, 그럼에도 불구하고 어렵게 임신이 된 경우에는 산모와 태아에게 각각 미칠 수 있는 이환율과 사망률을 심각하게 고려하여 임신을 지속할 것인지 또는 종결할 것인지를 결정해야만 한다. 그러나 아직까지 간경변 환자에서의 임신에 관한 보고는 많지 않기 때문에 그 관리나 치료에 있어서 명확한 지침은 없는 실정이고, 특히 외국 보고들은 대상 환자들이 대개 알코올성 간경변으로서 주로 바이러스성 간경변이 많은 국내의 사정과는 차이가 있을 수 있다. 한편, 간경변 환자에서 임신이 되는 경우 간기능의 악화 여부에 대해서도 아직 논란이 있다. 저자들은 B형 간염에 의한 간경변과 임신 23주 상태에서 내원한 36세 여자 환자에서 고빌리루빈혈증과 저알부민혈증 등의 저하된 간기능이 치료적 임신 종결에 의해 호전되는 것을 관찰하여 임신이 간경변 환자의 간기능을 악화시키는 요인으로 작용하는 경우를 경험하였기에 보고하는 바이며, 그간 국내에 보고된 증례들의 임상적 특징과 임신의 결과를 정리 및 분석하여 향후 진료에 도움이 되고자 하였다. Pregnancy is rarely encountered in women with liver cirrhosis, but can occur in all forms of liver cirrhosis. The amount of data regarding pregnancy in cirrhotic patients is not great and thus no clear-cut guidelines for management can be outlined. Another interesting point of pregnancy in liver cirrhosis would be how pregnancy affects liver function in cirrhotic patients. In korea, only 6 pregnancies in 5 patients have been reported. Recently, we experienced a case of pregnancy in a patient with liver cirrhosis. A 36 year-old, primigravida woman presented at 23 weeks of gestation. B-viral liver cirrhosis was diagnosed 2 months earlier when she had developed generalized edema and ascites. We observed a recovery of hyperbilirubinemia and hypoalbuminemia after a therapeutic termination of pregnancy. This case may illustrate that pregnancy can deteriorate liver function in some patients with liver cirrhosis. We report this case with an analysis of the reported cases in Korea (Korean J Med 64:119-124, 2003)
상부위장관 출혈을 동반한 위 기생충성 호산구성 육아종 1예

The localized eosinophilic granulomatous lesions of the stomach are rare benign tumorous conditions resembling submucosal tumors. They can be divided into two types. One is an inflammatory fibroid polyp. The other is an eosinophilic granuloma due to migration of Anisakis-type larva in the alimentary tract. The latter is usually found in the gastric body and anterior wall of the angle, and appears as a submucosal tumor. Histologically, the granuloma exhibits a characteristic lamellated structure consisting of a necrotic center with or without the worm, surrounded by layers of granulation tissue and eosinophilic infiltration. The present case is a 50 year-old male presenting with an episode of profuse melena. An emergency esophagogastroduodenoscopy revealed a 2x1.5cm sized, irregularly shaped ulcerative lesion with elevated margins and prominent folds convergence. Despite the endoscopic injection of hypertonic saline-epinephrine solution due to a recent bleeding stigmata, the patient experienced a rebleeding during hospitalization, The locally excised specimen showed an eosinophilic granuloma having a central necrosis. Although the larval body of Anisakis was not found, the lesion was diagnosed as a parasitic eosinophilic granuloma of the stomach.
