This study was conducted to investigate whether there were any differences in the body image perception, dietary behavior and maternal dietary guidance between an obese group ("OG") and a normal weight group ("NWG"), and furthermore, to provide basic informations for comprehensive educational programs for obese children. For this purpose, the questionnaire method was used. The subjects were 1,501 elementary school children, in the 4th to the 6th grades in Seoul, Busan, Daegu, Gwangju, and Andong, and their mothers (1,459). The percentage of the children who misperceive their body image was higher among the girls (30.4%) than the boys (22.6%). The average scores for balanced dietary behavior as assessed by the children was higher in the OG than in NWG; the average scores for dietary control as assessed by their mothers was higher in the NWG than in the OG. The scores for dietary behavior as assessed by the children was different from those as assessed by their mothers. Assuming that the mothers would give more correct and balanced answers, the development of a reliable questionnaire for dietary behavior that could be more accurately answered by the children is necessary. Maternal dietary guidance for dietary control was more frequently given in the OG as compared with the NWG and more frequently in girls as compared with boys ; while that for balanced diet was more in the NWG as compared with the OG. The worse the mothers estimate of the dietary behavior for their children, the more they tried to guide their children in dietary behavior. It is recommended that the children should be taught to correctly recognize the degree of their obesity, and receive the appropriate educational program accordingly, including the maternal dietary guidance.

A fifty year old Korean female was admitted with a few months history of general malaise. On admission, positive HBs Ag, negative HBs Ab and HBe Ag was negative. The liver function tests showed AST 274 U/L, ALT 126 U/L, CEA 1.87 ng/ml. With the clinical impression of chronic hepatitis B, abdominal CT and ERCP were performed and demonstrated a narrowing of the distal common bile duct suggesting a malignant etiology. The Whipple's procedure was done. The intraoperative finding revealed neoplastic involvement of the distal 1 cm of the common bile duct with severe narrowing and proximal dilatation. Microscopic findings demonstrated cystically dilated ductular structures and intervening irregular hypertrophic smooth muscle bundles.

Anisakiasis of the gastrointestinal tract is caused by the ingestion of raw fish or uncooked foods infested with Anisakis larvae belonging to the subfamily Anisakidae. With the increasing popularity of Japanese cuisine such as sashimi in Korea, the incidence of anisakiasis is expected to increase. The entire gastrointestinal tract from the esophagus to the rectum can be involved. Colonic anisakiasis is rare in comparison with gastric involvement. We report the anisakiasis concurrently invading the stomach, ileocecal valve and transverse colon treated by endoscopy with a brief review of the relevant literature.

BACKGROUND/AIMS: The detection and removal of colorectal polyps are important for secondary prevention of colorectal cancer. We investigated the characteristics and histopathologic finding of polyps to better plan their management. METHODS: We analyzed 334 patients who underwent polypectomies for 770 colorectal polyps between October, 2005 and April, 2007 at Bong Seng Memorial Hospital. RESULTS: Colorectal polyps were frequent in the sixth decade in both sexes. The ratio of male to female patients was 1.72:1. Abdominal pain/discomfort was the most common symptom (34.4%), and the most common site of polyp localization was the rectosigmoid colon. Histopathologic examination showed tubular adenomas (54.6%), hyperplastic polyps (36.4%), and inflammatory polyps (5.6%). Adenomatous polyps were more common in patients with multiple polyps than in patients with a single polyp. Adenomatous polyps with villous histology were more common in patients with large polyps than in patients with small polyps. Non-neoplastic polyps were common before the fifth decade. Neoplastic polyps were common past the fifth decade. CONCLUSIONS: In this study, tubular adenomas were frequently found on histopathologic examination, sessile type were frequently found on gross examination, and colorectal polyps were found principally in the rectosigmoid colon. Neoplastic polyps were more frequent in patients beyond the fifth decade. There fore colonoscopy examination is recommended for secondary prevention of colon cancer.

BACKGROUND: Poor HLA matched donors may become an additional organ source for renal transplantation. This study is conducted to predict the clinical outcomes of renal transplantation in a poor HLA matched group (0 or 1 or 2 HLA matching) by comparing them with those of HLA haploidentical group. METHODS: This study compared a poor HLA matched group (N=89) with HLA haploidentical group (N=79) to analyze differences between two groups in graft survival, incidence of acute rejection, cause of graft failure, posttransplant serum creatinine at 1, 2, 3, 5 years. Total 168 cases, appeared in the medical records for more than six months in Bong-Saeng Hospital, from December, 1984 to March, 2004 were traced and identified as relevant cases for this study. RESULTS: Allograft survival rate at 1, 3, 5, 10 years for poor HLA matched group and HLA haploidentical group were 100%, 98.6%, 95.4%, 72.5% and 100%, 100%, 96.1%, 86.2% (p=not significant) respectively. Acute rejection developed in 25.8% of poor HLA matched group versus 18.9% of HLA haploidentical group (p=not significant). The most common causes of graft failure in both groups were chronic rejection. CONCLUSIONS: It should be actively encouraged to consider renal transplantation in a poor HLA matched group as the results of this study support that the clinical outcomes of renal transplantation in a poor HLA matched group are equivalent to those of HLA haploidentical group.

PURPOSE: Numerous investigations have been conducted in order to determine the potential carcinogenic or chemopreventive activity of capsaicin. The aim of this study is to characterize the effects of capsaicin on colon cancer cells, and provide valuable information concerning the application of capsaicin in chemoprevention as well as for therapeutic purposes. METHODS: CoLo320DM and LoVo cells (human colon cancer cell line) were treated with capsaicin. In order to access cell viability and altered morphology, an MTT assay was performed and the cells were microscopically examined. Decreasing DNA staining was accessed by FACS. The cells were stained with FITC labeled annexin V and analyzed by FACS to detect cellular membrane alteration during apoptosis. The cells were stained with DiOC6(3) and Hydroethidine and analyzed by FACS in order to access ROS and dleta psi m. RESULTS: Capsaicin decreased cell viability in a dose-dependent manner. Capsaicin produced a cell morphology corresponding to the apoptotic features including cell shrinkage and chromatic condensation. Capsaicin treated cells induced a loss of nuclear DNA leading to hypoploidy in a dose-dependent manner. Cells were excluded by double staining with PI and FITC labeled annexin v and detected by FACS. We show that treatment of CoLo320DM, L0Vo cells with increasing concentrations of capsaicin parallel an increase in the percentage of red fluorescent cells (HE-->Eth) that reflect ROS hypergeneration and a decrease in the percentage of green fluorescent cells that reflect delta psi m disruption. CONCLUSION: These results clearly demonstrate that capsaicin-induced colon cancer cell death is apoptotic.

The anal canal is the most distal part of the gastrointestinal tract, and it is developed and formed during the embryonic period. Infection is the most common disease process that occurs around the anorectum, yet tumors or cysts are occasionally encountered. The abnormal development of these parts of the gastrointestinal track during the embryonic period can result in congenital lesions that are discovered in young children or adults. A 72-year-old woman presented to us with postprandial lower abdominal discomfort and fecal incontinence. An anorectal mass was felt on the rectal examination. The colonoscopy demonstrated a submucosal tumor that was closely located to the anorectal junction. The tumor was excised with a snare and it was diagnosed as an analgland cyst due to the histologic features. It is necessary to differentiate anal gland cyst from the other diseases that have submucosal characters, such as carcinoid tumor.

BACKGROUND/AIMS: This study was designed to evaluate normal Korean pancreaticobiliary ducts and to assess the prevalence and pattern of variations and anomalies of theses structures. METHODS: We performed this multicenter study in which 7 university hospitals in Korea participated from March 1997 until June 1999. Total 10,243 ERCP cases were reviewed during this study period. RESULTS: 1) Maximal and midportion diameters of common bile ducts were 6.4+/-1.8 mm and 5.5+/-1.7 mm, respectively. Maximal and midportion diameters of pancreas head were 3.2+/-1.1 mm and 2.7+/-1.0 mm, respectively. Pancreaticobiliary duct diameters of subjects above the age of 40 were greater than those of subjects below the age of 40 (p<0.05). 2) The prevalence of choledochal cyst was 0.32%. The prevalence of gallbladder anomalies and anomalous union of pancreaticobiliary duct was 4.2% and 4.1%, respectively. The prevalence of pancreas divisum and annular pancreas was 0.49% and 0.05%, respectively. The most common type of pancreaticobiliary duct union was V shape (60.2%), followed by U shape (23.7%) and Y shape (16.1%). CONCLUSIONS: Understanding normal pancreaticobiliary structures and being aware of the prevalence and pattern of variations and anomalies of pancreaticobiliary structures will be helpful to diagnose and treat patients with pancreaticobiliary problems.

BACKGROUND AND OBJECTIVES: The intracoronary injection of acetylcholine (Ach) has been shown to induce coronary spasms in patients with variant angina. Clinical significance and angiographic characteristics of patients with a significant response to lower Ach dosages are as-yet non-clarified compared with patients responding to higher Ach doses. SUBJECTS AND METHODS: A total of 3034 consecutive patients underwent coronary angiography with Ach provocation tests from January 2004 to August 2010. Ach was injected in incremental doses of 20, 50, 100 microg into the left coronary artery. Significant coronary artery spasm was defined as focal or diffuse severe transient luminal narrowing (>70%) with/without chest pain or ST-T change on the electrocardiogram (ECG). We compared the clinical and angiographic characteristics of patients who responded to a lower Ach dose (20 or 50 microg, n=556) to those that responded to a higher Ach dose (100 microg, n=860). RESULTS: The baseline clinical and procedural characteristics are well balanced between the two groups, except diabetes was higher in the lower Ach dose group and there were differences in medication history. After adjusting for confounding factors, the lower Ach dose group showed more frequent temporary ST elevation and atrioventricular block on the ECG. Furthermore, the group of patients who responded to the lower Ach dose was associated with a higher incidence of baseline and severe spasm than those who responded to a higher Ach dose. CONCLUSION: Patients with a significant response to a lower Ach dose were associated with more frequent ST elevation, baseline spasm, and more severe spasm compared with those who responded to a higher Ach dose, suggesting more intensive medical therapy with close clinical follow-up is required for those patients.
