We report here a case of a gastrointestinal stromal tumor (GIST) in the stomach that was diagnosed by endoscopic ultrasound-guided fine needle aspiration cytology (EUS-FNA). A 67 year old male patient underwent regular check-ups for five years due to the presence of a submucosal tumor that was found in the fundus of the stomach incidentally. EUS-FNA was performed to evaluate the tumor, which had increased in size from 1 cm to 2.8cm. A cytologic smear revealed cohesive sheets or clusters of spindle cells with elongated nuclei. Immunohistochemical staining revealed a strong positive reaction for c-kit and CD34, without any reaction for smooth muscle actin and Ki-67. Therefore, a diagnosis of GIST was made.

목적: 이번 연구는 원격 전이가 없는 식도암 환자에서 근치 목적으로 시행한 방사선 및 항암화학요법과 수술을 포함한 방사선 및 항암화학요법을 비교하여 두 치료법의 효용성과 생존율 차이를 알아보고자 하였다. 대상 및 방법: 1997년 1월부터 2005년 12월까지 원격 전이가 없는 절제 가능한 식도암 환자 88예를 대상으로 하였다. 이 후향 연구는 임상의학윤리위원회(IRB)의 승인을 받았다. 방사선은 5,000-5,500cGY를 조사하였고, 항암 약제는 수술 전 또는 후에 5-fluorouracil과 cisplatinum을 사용하였다. 전체 생존기간은 진단일부터 사망하거나 추적관찰 중간 종료기간인 2005년 12월까지를 기준으로 하였고 후향 분석하였다. 병기는 AJCC 기준에 따라 구분하였고, 생존율은 Kaplan-Meier method로 분석하였다. 결과: 근치 목적으로 방사선항암화학 병행요법으로 치료받은 환자는 61예였고 수술 치료와 더불어 방사선 치료와 항암화학요법을 시행한 환자는 27예였다. 두 군 간을 비교 시 조직형, 위치, 임상병기에는 유의한 차이가 없었으나, 평균나이는 수술한 그룹이 63±10세로 수술하지 않은 그룹인 69±8세보다 적었다. 중앙 추적기간은 17개월이었고(1-87개월), 5년 생존율은 방사선항암화학 병행치료군은 7%, 수술과 방사선항암화학 병행치료군은 4%였다. 방사선항암화학 병행치료를 받은 환자군의 중앙 생존기간은 11개월이며 수술과 더불어 방사선항암화학 병행치료를 받은 환자군의 중앙 생존기간은 10개월로 유의하지 않았다(p=0.697). 결론: 수술과 더불어 방사선항암화학 병행치료를 받은 환자군이 근치 목적으로 방사선 및 항암화학 병행치료를 받은 환자군에 비해 생존율 증가는 관찰되지 않았으나, 향후 많은 대상군과 장기 추적기간을 통한 전향 연구가 필요하다. Background/Aims: This study was designed to compare the survival rates between patients with localized esophgeal cancer who were treated with concurrent chemoradiation therapy without surgery and patients who were treated with concurrent chemoradiation therapy including surgery. Methods: Eighty-eight patients from January 1997 to December 2005 with locally advaned resectable esophageal cancer were selected and retrospectively analyzed. Survival period was defined as the time to death from the date of diagnosis or mid-monitor period of December 2005. Sixty-one patients were treated with chemoradiation therapy alone while twenty-seven patients were treated with chemoradiation therapy in addition to surgery as for curative intention. As for radiation therapy, 5,000-5,500 cGY was used. 5-Fluouracil and cisplatin were used for chemotherapy. The primary end point was overall survival time. The secondary end point was overall progression free survival time. Results: There was no significant difference in tissue type, location and clinical staging, but the median age was significantly younger in the group treated with surgery (63.4 years) than the group treated without surgery (68.8 years). Median period analyzed was 17.3 months. Five year survival rate for the group with chemoradiation alone was 7.4% and 4% for the group with surgery. The median survival rate was 11±3 months for the group with chemoradiation alone and 10±6 months for the group with surgery, in which there was no statistical difference (p=0.697). Conclusions: There was no significant increase in survival rate in patients who were treated by chemoradiation with surgery compared with chemoradiation alone. Further analysis in terms of prospective study is needed. (Korean J Gastroenterol 2009;53:15-22)

Pseudomembranous colitis (PMC) is known to be associated with the administration of antibiotics which alter normal gastrointestinal flora and allow overgrowth of Clostridium difficile. Most cases of rifampicin-induced PMC are seen in patients with pulmonary tuberculosis, but not with gastrointestinal tuberculosis. We report a case of PMC associated with rifampicin therapy in a patient with gastrointestinal tuberculosis. A 65-year-old female patient with rectal cancer and gastrointestinal tuberculosis was admitted due to abdominal pain and diarrhea. She was treated with anti-tuberculosis agents containing rifampicin. On colonoscopic examination, mucoid exudates and yellowish plaque lesions were observed. Anti-tuberculosis agents were stopped, and the patient was treated with metro-nidazole. Symptoms were relieved and did not recur when all the anti-tuberculosis agents except rifampicin were started again. When a patient complains of abdominal pain or diarrhea while taking rifampicin, the physician should consider the possibility of rifampicin-associated PMC. (Korean J Gastroenterol 2009;53:53-56)

As days go by, E-commerce is sharply increasing and direct oversea purchase is still hot. However, many problems arise in e-commerce and overseas direct purchase. In avoiding the problems, the reviews and comments can be helpful. This study is to sort out positive WOM and two-sided WOM from online WOM and find out which type of WOM is useful and what impact it has on the purchase intention. 2x2 factorial design method was used. The results of the research can be summarized as follows. First, Usefulness of information in a group exposed to two-sided WOM is bigger than in a group exposed to positive WOM. Second, Purchase intention in a group exposed to positive WOM is bigger than in a group exposed to two-sided WOM. In high involvement, two-sided WOM is more useful than positive WOM, but in low involvement, there is no difference between the usefulness of information two-sided WOM and positive WOM. In high involvement, there is no difference between the purchase intention of consumers with positive WOM and the ones with two-sided WOM. However, in low involvement, the purchase intention is more influenced by positive WOM than two-sided WOM.

Purpose - The purpose of this study is to investigate the effect of ethnocentrism on the corporate image and brand image among the various variables affecting consumers’ evaluations and attitudes toward domestic and foreign products and purchase intention. This study analyzes the effect of corporate image and brand image on the purchase intention of domestic smartphone products and US products for Korean consumers to identify the factors that influence ethnocentrism and provide them as a basis for establishing domestic and overseas marketing strategies. Research design, data & methodology - The survey for this study was conducted during January 10th through 20th in 2018. 250 copies of the questionnaire were distributed to Korean customers. The surveyed products were Samsung and LG smartphones in Korea, and iPhone in the United States. After excluding five copies of missing and unreliable responses, 245 copies of questionnaire were used in the research analysis. This study conducted that the survey questionnaires and confirmatory analysis were used for the reliability and validity of the study. SPSS 25 version and AMOS programs were used for the analysis. Results - In this research analysis, the stronger the ethnocentrism propensity, the more positively the corporate image and the brand image are influenced, and the corporate image and brand image are also found to increase the purchase intention. Therefore, in this study, Koreans’ ethnocentrism tendency is more influenced by corporate image and brand image in purchase intention. Conclusion - The results of this study show that the ethnocentric propensity of Koreans is not consistent with the results of previous research that negatively affects the evaluation and purchasing intention of foreign products. And this suggestion is something meaningful that ethnocentrism affects Korean consumers’ evaluation and purchasing intentions of foreign products but they can not find any significant difference, even if there are other various influencing factors

Inflammatory bowel disease often involves extra-intestinal organs. Cerebral thrombosis, portal vein thrombosis and pulmonary thrombosis have been reported. Deep vein thrombosis and pulmonary thromboembolism are significant causes of mortality in patients with inflammatory bowel disease. A 48-year-old woman was diagnosed as inflammatory bowel disease on colonoscopy and histology. We used hydrocortisone and mesalazine for the treatment of disease. Nineteen days later, she complained of abrupt dyspnea. Pulmonary CT angiography revealed a thromboembolism in right pulmonary arteries. After the treatment of heparin therapy, follow-up pulmonary CT angiography showed significant improvement of previously thrombosed pulmonary arteries. (Korean J Gastroenterol 2009;53:48-52)

Splenic artery aneurysms, no longer considered rare, occur in 10% of patients with liver cirrhosis and portal hypertension. But, spontaneous rupture of splenic artery aneurysm is a rare condition. Due to a fatal rupture, they are considered dangerous. Rupture is often the first and only symptom. With an increased index of suspicion and early aggressive treatment of asymptomatic splenic artery aneurysms, mortality has drastically decreased. We experienced a case of splenic artery aneurysm rupture associated with liver cirrhosis. A 40-year-old female patient was admitted due to left upper quadrant pain. The patient was diagnosed as splenic artery aneurysm rupture with liver cirrhosis by celiac arteriogram and computed tomography. The patient was treated with splenic artery embolization and splenectomy, but the patient died. In this paper, the case of splenic artery aneurysm rupture associated with liver cirrhosis is reported with review of relevant literatures.(Korean J Med 61:302-306, 2001)
