Purpose: The aim of this study was to identify risk factors influencing permanent stomas after low anterior resection with temporary stomas for rectal cancer. Materialsand Methods: A total of 2528 consecutive rectal cancer patients who had undergonelow anterior resection were retrospectively reviewed. Risk factors for permanentstomas were evaluated among these patients. Results: Among 2528 cases of rectal cancer, a total of 231 patients had a temporary diverting stoma. Among these cases, 217 (93.9%) received a stoma reversal. The median period between primary surgery and stoma reversal was 7.5 months. The temporary and permanentstoma groups consisted of 203 and 28 patients, respectively. Multivariate analysis showed that independent risk factors for permanent stomas were anastomotic-related complications (p=0.001) and local recurrence (p=0.001). The 5-year overall survival for the temporary and permanent stoma groups were 87.0% and 70.5%, respectively (p<0.001). Conclusion: Rectal cancer patients who have temporarystomas after low anterior resection with local recurrence and anastomotic-related complications may be at increased risk for permanent stoma.

목적: 위에 발생하는 신경내분비 종양은 국내에서도 그 보고가 드문 매우 독특한 조직형인데, 이 종양의 임상병리 학적 특징들에 대해 알아보고자 하였다. 대상 및 방법: 1999년 1월부터 2007년 8월까지 고신대학교 의과대학 외과학교실에서 위암으로 수술받은 4,159예 중 신경내분비 종양으로 진단받은 13예를 대상으로 의무기록 및 조직 표본을 후향적으로 분석하였다. 결과: 위 신경내분비 종양은 남자 11예, 여자 2예였고, 평 균나이는 54.9세(42∼72)였으며, 주증상은 상복부 통증과 속 쓰림이 많았다. 점막 또는 점막하 종양 2예를 제외하고 나 머지 9예는 모두 근육층 이상을 침범한 진행성이었고, 종 양의 평균 크기는 7.0 cm (0.7∼15)였다. WHO 분류법에 의 한 내분비 종양의 유형은 제 3형이 8예, 제 4형이 4예, 제 1형이 1예였다. 림프절 전이는 11예에서 있었고, 추적 기간 내 재발한 4명의 환자 모두 제 3형과 제 4형이었고, 재발 한 장기는 간이 2예, 다장기(복막, 폐) 1예, 다장기(간, 췌장, 십이지장) 1예였고, 생존 기간은 평균 12.8개월이었다. 결론: 위에 발생하는 신경내분비 종양은 진단 당시 진행 된 경우가 많았고 간 전이를 잘 하였으며 예후가 나쁜 독 특한 조직형이다.

Acute gastrointestinal (GI) bleeding is a common cause of emergency department admission and hospitalization. Diagnosis and treatment requires promptly with a multidisciplinary approach to reduce morbidity and mortality of acute GI bleeding. Many diagnostic modalities are being used in the evaluation of GI bleeding, each with its own strengths and weaknesses. With the recent advances in technology, computed tomography (CT) angiography has become an effective first-line method for imaging the cause of GI bleeding to guide management. The purpose of this review is to discuss diagnostic modalities of GI bleeding, with a focus on the emerging role of CT angiography.

The radon concentrations were measured to survey distribution of radon concentrations in Seoul subway stations. The radon concentrations in air and water were measured at seventeen subway stations(Mapo, Chungjongno, Sodaemun, Kwanghwamun, Chongno3ga, Ulchiro4ga, Tangdaemun, Sangildong on Line 5;Nowon, Chunggye, Hagye, Kongnung, Taenung, Mokkol, Chunghwa, Sangbong, Myomok on Line 7) using the $RAdtrak^{TM}$ radon gas detector, Pylon AB-5 continuous passive radon detector and liquid scintillation counting method from January to May 1999. The major results obtained from this study were as follows: The long-term mean concentrations of radon were $61.8\;Bq/m^3$ in office, $78.9\;Bq/m^3$ in platform, $38.2\;Bq/m^3$ in concourse and $20.1\;Bq/m^3$ in outdoor, respectively. These levels were less than the action level ($148\;Bq/m^3$) of the U.S. EPA. The highest level of short-term mean concentrations was $116.55\;Bq/m^3$ at Chongno3ga station on the 5th line subway stations, while the lowest mean concentration was $19.55\;Bq/m^3$ at Mokkol station on the 7th line subway stations. The highest concentration of radon in the road water and storing underground water in the subway stations was $234.7\;KBq/m^3\;and\;155.5\;KBq/m^3$ in Sodaemun subway station, respectively. The results suggest that radon concentration in subway stations seems to be affected by ventilation and radon concentratin in underground water in the subway stations.

Background: Tobacco use is a leading cause of countless deaths and disabilities worldwide. An estimated 11 million Korean adults were still using tobacco in 2020, according to the Korea National Health and Nutrition Examination Survey. This review aims to explain the current trends in tobacco use, sales, cessation, and control policies in South Korea. Current Concepts: Heated tobacco products (HTPs), a hybrid between conventional and electronic cigarettes, were first launched in South Korea in June 2017. Advertisements stating that HTPs are odorless, tar-free, and less harmful to health have caused sales of HTPs to grow quickly over the past 5 years, such that they account for about 15% of the total tobacco market. According to national smoking rate statistics and tobacco sales trends, declines in current smoking rates have slowed and even risen in some groups, and declines in total tobacco sales have slowed but also risen again during the coronavirus 19 pandemic. In addition, the number of visitors to smoking cessation clinics decreased just after the advent of HTPs and social distancing policies triggered by the coronavirus. Nicotine replacement therapy can serve as a drug therapy for smoking cessation, or bupropion and varenicline can be prescribed. Korea’s representative tobacco control policies include the tax increase policy, non-smoking area policy, cigarette pack warning picture policy, and support policy for visiting smoking cessation clinics. Discussion and Conclusion: There is a pressing need to reflect tobacco control policies in line with changes in tobacco user behaviors and tobacco company marketing strategies.
