Inflammatory bowel diseases (IBD) is heterogeneous, chronic relapsing disorder. Inappropriate and exaggerated immune response for the luminal antigen is known as a main pathogenesis. Genetic, infectious, and environmental factors are responsible for unbalanced immune response, but the definite pathogenesis is still unclear. Genetic factor is the most important role of all. That is based on high concordance rate of identical twins and family history. The incident rate and prevalence of IBD for the Asian population is relatively lower than Western population, and the lack of NOD2 or TLR4 genetic polymorphisms in Korea and Japanese population suggests the difference in genetic background between Asian and Western population. In Korea, the case of familial aggregation of IBD is pretty rare. We report a case of the daughter with ulcerative colitis and her mother with Crohn`s disease who have a -159C/T promoter polymorphism of CD14 gene for IBD. (Korean J Gastroenterol 2010;55:336-339)

목적: 현재 H. pylori 제균치료는 소화성 궤양 환자에서만 인정을 받고, 위암이나 위염 환자를 대상으로 적용 범위를 확대 적용하는 것에는 아직 논란의 여지가 있다. 최근 들어 표준 삼제요법의 제균율이 점차 감소하는 경향을 보이며, 이는 항생제 내성의 증가 및 환자의 순응도 감소와 가장 큰 연관이 있으나, 다른 여러 요인들도 제균율에 영향을 미치는 것으로 알려져 있다. 저자들은 진료과에 따른 제균율의 차이가 있는지 알아보기 위해 진료과별 제균치료 현황과 제균율, 그리고 내시경적인 궤양에 대한 적용 빈도를 조사하였다. 대상 및 방법: 2003년 1월부터 2007년 6월까지 가톨릭대학교 성빈센트병원에서 H. pylori 제균요법을 시행했던 환자를 대상으로 소화기내과, 일반내과, 가정의학과별로 제균율의 차이를 후향 조사하였다. 대상 환자는 2,050명으로 의료영상 저장 전송 체계(PACS)를 이용하여 3명의 내시경전문의가 각각의 내시경 소견을 다시 판독하여 내시경적인 미란과 궤양을 구분하였다. 결과: 일차 삼제요법에 대한 제균율은 82.5%였고, 이차 사제요법에 대한 제균율은 71.2%였다. 일차 진료를 담당하는 가정의학과와 내과 일반에서 소화기내과에 비해 내시경적인 미란에 대해 제균요법을 시행하는 빈도가 의미 있게 높았고, 전체 제균율과 내시경적인 궤양에 대한 제균율은 유의하게 낮았다. 결론: 일차 진료과에서 적용한 H. pylori 제균요법은 미란 등 부적절한 제균대상이 많았다. 전체적인 제균율이나 내시경적인 궤양에 대한 제균율은 소화기내과가 일차 진료과에 비해 의미 있게 높았고, 이것은 여러 가지 복합적인 요인이 작용하고 있을 것이며, 그 중에서도 복약에 대한 환자의 순응도가 중요한 역할을 할 것으로 본다. Background/Aims: Eradication rates of Helicobacter pylori (H. pylori) tend to decrease over the last few years. Apart from the antibiotic resistance and patient`s compliance, various factors have an influence on the efficacy of eradication therapy. We analyzed the inter-departmental differences in the eradication therapy for H. pylori infection. Methods: Between January 2003 and June 2007, total 3,072 eradication regimens were prescribed to patients. Eradication rates according to departments-gastroenterology (GE), general internal medicine (IM) and family medicine (FM)-were analyzed retrospectively. Results: The overall eradication rate of first-line triple therapy was 82.5% and second-line quadruple therapy was 71.2%. In the department of IM and FM, the eradication therapy was applied more frequently to the patients with erosion only, not ulcer. Overall eradication rates according to the departments were 87.0% in GE, 81.1% in IM and 77.2% in FM (p=0.02 GE vs. IM and p<0.01 GE vs. FM, respectively). Eradication rate in patients with peptic ulcer was also significantly higher in GE compared with IM or FM. Conclusions: In primary clinic (IM and FM), the eradication therapy was frequently applied to erosion. The eradication rates of H. pylori in GE department were significantly higher than those of IM or FM. Inter-departmental differences of the eradication rate might be caused by patients` compliance to prescribed medication. (Korean J Gastroenterol 2009;53:221-227)

Carcinosarcoma of the esophagus is a rare malignancy accounting for approximately 1-2% of all esophageal neoplasms. It presents as a bulky intraluminal polypoid lesion mainly in the mid to lower esophagus, which harbors both carcinomatous and sarcomatous components histologically. It often presents relatively early because of its rapid intraluminal growth. We report the case of a 69-year-old man who had suffered from dysphagia for 1 month. He was previously admitted to the hospital due to corrosive esophagitis caused by ingestion of acetic acid. Endoscopy and radiological studies revealed a bulky polypoid mass with superficial ulcerations and mucosal friability, measuring 10 cm in length approximately, in the mid-esophagus. Subtotal esophagectomy with esophagogastrostomy was done. Microscopically it was composed of sarcomatous component intermingled with squamous cell carcinoma. Immunohistochemical stains reveal cytokeratin, 34βE12, and p63 positivity in the nests of carcinoma, and desmin and vimentin positivity in the spindle cells of sarcomatous stoma.

Background : Pyogenic liver abscess is an acute infectious disease caused by bacteria and can become severe and potentially life-threatening, with a mortality rate of 6-18%. The purpose of this study is to provide the basic informations for the management of liver abscess and the choice of the most effective and economic antibiotics. Materials and Methods : We investigated clinical, laboratory, radiologic findings and the results of bacteriological studies retrospectively by reviewing the medical records of 141 cases of pyogenic liver abscess patients, admitted to Catholic University St Vincent's Hospital from January 1998 to December 2007. Results : Patients demographics revealed a mean age of 57.1, (age: 18 to 87), and 71 of the 141 patients were male (50.4%). Cure was achieved in 51 (98.1%) of the 52 patients who were treated with the combination of percutaneous drainage and antibiotics, and in 80 (90.0%) of 89 patients who were treated only with antibiotics. However, there were no significant differences in mortality (P=0.092) and the time to defervescence between both groups. The mean duration of percutaneous drainage was 15.8U9.7 days. Sixty-four of 141 patients showed positive culture results, and K. pneumoniae (70.3%) was the most common organism. Among 45 K. pneumoniae, the rates of resistance were 73.3% to ampicillin, 66.7% to piperacillin, 8.9% to cefazolin, 2.2% to cefuroxime, 0% to ceftriaxone, and 0% to ciprofloxacin. Conclusions : Combination treatment of intravenous antibiotics and percutaneous drainage was effective for the treatment of pyogenic liver abscess, Initial broad spectrum antibiotic coverage and then switch to first or second cephalosporin according to the susceptibility results, could be recommended especially in patients with monomicrobial K. pneumoniae liver abscess.
