Carcinoids are slow growing neuroendocrine tumors (NET) originating in the enterochromaffin cells of the gastrointestinal tract. In previous studies, rectal NET comprised only about 1% of all anorectal neoplasms, however, the incidence of rectal NET has shown a recent increase. Typically, rectal NET presents as a single subepithelial nodule, and multicentricity of rectal NETs is rare, with reported incidence of 2-4.5%. Due to the rarity of multiple rectal NETs, there is no consensus or guidelines for treatment of multiple rectal NETs. However, NETs of the rectum that are less than 10 mm in diameter and do not infiltrate the muscularis propria, without distant metastasis, can be removed by endoscopy, as with solitary rectal NET. We encountered five cases of multiple rectal NETs which were treated successfully by endoscopy. (Korean J Gastroenterol 2014,64:103-109)

Seungchon Weir was constructed in 2010 on the downstream region of Yeongsan River watershed for four major river projects. The purpose of our study was to determine whether fish compositions and distributions differ between the upper Uw and lower regions Lw of Seungchon Weir during May December 2011 along with hydroacoustic fish surveys using Eco Sounder monitoring EsM technique. Total number of fish species sampled by conventional fish sampling at all sites was 29, and 21 and 24 species occurred in the Uw and Lw, respectively. Most dominant species was Hemiculter eigenmanni 43% in the Uw and Opsaiichthys uncirostris 21% in the Lw indicating a distinct differences of the species composition. According to hydroacoustic approach of EsM, fish density was significantly higher p<0.05 in the Lw section of 250 m than any other sections, This outcome indicates that fishes moving toward the upstream were blocked by weir construction. According to analysis of tolerance guilds, tolerant species TS were made of 88% and 79% in the Uw and Lw region, respectively, while the proportions of sensitive species were < 0.1% of the total in the both regions. Trophic guild analysis showed that the proportion of omnivore species were 58% and 40% in the Uw and Lw region, respectively, while insectivores were made of 16% and 21% in the Uw and Lw region, respectively. Both analyses of tolerance guilds and trophic guilds indicate the biological degradation fo the waterbody. Fish community structure analysis, based on species diversity, dominance, and evenness indices, showed higher community stability in the Lw region than Uw region. Exotic species of largemouth bass were largely increased in this survey 14% , compared to the past <1% , indicating a modification of fish trophic structure.

Fish passage asssessments were conducted in the fishway at Juksan Weir, which was constructed as a four-major rivers project in the downstream area of Youngsan-River Watershed. For the research, fish-movements/migrations were analyzed for seven times from April ~ October, 2013 using an approach of fish trap-setting. Fish fauna and compositions were analyzed in the fishway, and seasonal- and diel-movement patterns were analyzed in relation to current velocity in the fishway. Also, abundances of exotic fishes such as bluegill sunfish (Lepomis macrochirus), large-mouth bass (Micropterus salmoides), and white curcian carp (Carassius cuvieri) were monitored in the fishway. Current velocity(n = 18) in the fishway showed large variations (0.82 ± 0.63 m/s) depending on the location of the fish trap-setting and this physical factor influenced the fish movements. Fish movements, based on the CPUE of individuals, in the fishway was greater in slower velocity (mean: 0.36 m/s, range: 0.10~1.54 m/s) than faster velocity (mean: 1.51 m/s, range: 0.90~1.90 m/s). Seasonal analysis of fish movements showed that most frequent uses (8 speices and 591 individuals, 66.2% of the total) of the fishway occurred in spring period(i.e., June). Diel movement analysis, in the mean time, showed highest in the time period of 00:00 ~ 3:00 am (7 species and 281 individuals, 20.9% of the total). The efficient managements in the fishway at Juksan Weir are required in relation to the hydrological regime.

Plummer-Vinson syndrome manifests as cervical dysphagia, iron deficiency anemia, an upper esophageal web, and atrophic glossitis. The cause of the esophageal web is thought to be iron deficiency anemia; however, the cause of Plummer-Vinson syndrome has not been established. Crohn`s disease is usually accompanied by malnutrition and iron deficiency anemia; however, no case of concomitant Crohn`s disease and Plummer-Vinson syndrome with aggravated malnutrition and anemia has been previously reported. Here, we report on a rare case of Plummer-Vinson syndrome in a Crohn`s disease patient, which caused malnutrition and constipation.

The objectives of this study were to determine trophic sate of agricultural reservoirs within the four major watersheds and evaluate the ecosystem health using the multi- metric fish modeling approach of Lentic Ecosystem Health Assessments (LEHAs). Agricultural reservoirs, based on Trophic State Index (TSI) ranged from mesotrophic to hypertrophic depending on the intensity of Asian monsoon. Regression analysis of N:P ratios showed a negative linear function (R2 = 0.698, p < 0.0001) with TP values, but not with TN (p = 0.939). The plots of "TSI (CHL) - TSI (TP)" and "TSI (CHL) - TSI (SD)" suggest that other factors other than phosphorus limited algal biomass (CHL - TP < 0), and that non-algal particles dominated light attenuation (CHL - SD < 0). Regression model of fish trophic component against TP showed that the proportion of omnivore (OM) and insectivore fish (IS) had a positive (R2 = 0.679, p < 0.01) and negative linear function (R2 = 0.403, p < 0.05) with TP, respectively. Values of multi-metric LEHAs model averaged 26 6.5, indicating a "Fair" conditions. Overall, the ecosystem health was directly influenced by organic matter pollution and high algal production.

Background/Aims: The eradication rates of Helicobacter pylori infection have been reported to have decreased over the years due to antibiotics resistance. The aim of this study is to investigate the trend of eradication rates of first-line triple therapy for H. pylori over the past 13 year period, and to evaluate factors affecting H. pylori eradication in Daegu and Gyeongsangbuk-do, Korea. Methods: A total of 2,982 patients with H. pylori infection who were treated with either 1 week or 2 weeks first-line therapy (proton pump inhibitor [PPI], amoxicillin, and clarithromycin) from January 1999 through December 2011 were included in this study. Data were collected by retrospectively reviewing the medical records. Results: The overall H. pylori eradication rate was 87.2%. The eradication rates from 1999 to 2011 fluctuated between 78.0% and 95.7%, but no definite evidence of a decreasing tendency was seen over the 13 year period (p=0.113). Furthermore, there was no significant difference in the eradication rate according to the duration of therapy (p=0.592). However, there was a significant difference in the eradication rate among various PPIs (p<0.01). Conclusions: There was no decreasing trend in the H. pylori eradication rate over the past 13 years in Daegu and Gyeongsangbuk-do, Korea. There also was no difference in the eradication rates depending on duration of therapy. However, a significant difference was noted among various PPIs. (Korean J Gastroenterol 2014;63:82-89)
