PURPOSE: The aim of this study was to review the outcome of local control after the local excision for T1/T2 rectal cancers and, thus, to assess its effectiveness as an alternative to a more radical resection. METHODS: This retrospective study analyzed 23 patients with T1/T2 rectal cancer treated by local excision (LE), and their results were compared with the results for 22 patients with rectal cancer of the same stage treated by a radical resection (RR). All patients with pT2 lesions in the LE group received postoperative adjuvant chemoradiation. The outcomes were defined as 5-year local-recurrence-free survival (LRFS). The median follow-up was 72 (range, 40~92) months. RESULTS: Recurrence occurred in 4 patients (pT1, 1; pT2, 3) in the LE group and in 3 patients (all pT2) in the the RR group. One patient with vascular invasion (T2N1M0) in the RR group showed multiple liver metastases at 23 months postoperatively. The difference in 5-year LRFS was not statistically significant between the two groups. In the LE group, the 5-year LRFS for pT2 lesions was significantly less favorable than that for pT1 lesions (40% vs. 94%; P= 0.005). The 5-year LRFS for pT2 in the RR group was more favorable than that in the LE group, although the difference was not statistically significant (76.9% vs. 40%, P=0.138). CONSLUSIONS: Local excision provides a favorable local control for pT1 rectal cancers. A more radical resection, however, remains an effective surgical option for pT2 lesions because local excision, even combined with adjuvant chemoradiation, showed substantial local recurrences.

The purpose of this study was to identify the effect of individual emotional characteristics (empathetic concern and emotional contagion) on emotional labor (frequency of emotional display, intensity and variety of emotional display, surface acting, and deep acting) of school dietitians. Data was collected through a questionnaire survey of 309 school dietitians and then analyzed statistically by SPSS 18.0 package program. The results of this study were as follows: empathetic concern (3.93) occurred more often than emotional contagion (3.22) in school dietitians. The older (p < 0.001) and more experienced (p < 0.01) they were, the higher empathetic concern they had. It showed that married dieticians (p < 0.001), nutrition teachers (p < 0.01), and dieticians who were working in elementary schools (p < 0.01) had a higher rate of empathetic concern than single dieticians, non-nutrition teachers, and dieticians who were working in middle and high schools, respectively. Their level of emotional labor was the highest in deep acting (3.32), followed by surface acting (3.28), frequency (3.12), intensity and variety (3.09). According to multiple regression analysis, emotional contagion proved to be strongly significant and positively related to frequency of emotional display (beta = 0.257, p < 0.001). Both empathetic concern (beta = 0.117, p < 0.05) and emotional contagion (beta = 0.162, p < 0.01) were positively related to intensity and variety of emotional display, and empathetic concern (beta = 0.173, p < 0.01) had also an effect on deep acting. These results suggested that the emotional labor of school dietitians should be managed on the organizational viewpoint, not a personal matter.

The purpose of this study was to compare wage treatment and the employment environment of school foodservice employees before and after conversion to indefinite contract status since September 2012 when the Ordinance on the Appointment of Education Officials (indefinite contract) under the Gangwon Provincial Superintendent of Education was applied as well as to examine the effects of wage treatment and the employment environment on job stability. The questionnaire survey was conducted from March 31 to April 10, 2017 for school foodservice employees working at 97 schools in Gangwon province. A total of 477 questionnaires were distributed and 470 questionnaires were used for the analysis. Statistical analysis was conducted using SPSS Window Ver.18.0. The detailed results of this study were as follows. First, wage treatment (2.29 vs. 3.16), employment environment (3.45 vs. 4.22) and job stability (1.88 vs. 2.35) revealed significantly positive perceptions after conversion to indefinite contract status compared to before conversion. Second, after analyzing leading factors influencing job stability, it was revealed that wage treatment (before: βâ = 0.516, P < 0.05; after: βâ=0.465, P < 0.05) had a positive (+) effect on job stability, whereas employment environment did not affect job stability. In conclusion, in the context that most school foodservice employees are contract employees, this study is significant in that the changes in the employment policies of the national government and education office were confirmed to have effects on school foodservice employees.

Benign tumors of the esophagus occur rarely as compared with the incidence of carcinomas. Among the benign tumors of the esophagus such as leiomyoma, lipoma, hemangioma, papilioma. polyp, cystetc. leiomyoma is the most common, although less than 10 percents of leiomyomas of the gastrointestinal tract are found in the esophagus. Most of leiomyomas of the esophagus present as solitary lesions but multiple tumors occur in about 4 percents of cases. Leiomyomas of the esophagus are diagnosed by thorough clinical evaluation, esophagogram and upper gastrofiberscopic examination but histological confirmation requires surgical or necropsy specimens. Occasionally gastrofiberscopic polypectomized specimens are used. We report one case of multiple leiomyomas of the esophagus located in between 25 cm and 40 cm distance from the incisor in a 38-year-old man who complained of vague substernal discomfort for about 10 years. Gastrofiberscopic polypectomized specimen was used for preoperative histological confirmation. The pathologic examination of the specimen showed leiomyoma of the esophagus.

The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed by Stoll's egg-counting technique, and praziquantel was administered to positive cases. The egg-positive rates for Clonorchis sinensis and Metagonimus species were 9.3% and 5.5%, respectively, and the double infection rate was 3.5%. The numbers of eggs per gram (EPG) of feces of C. sinensis and Metagonimus sp. were 918 +/-1.463 and 711+/-947, respectively. The egg-positive rates for C. sinensis and Metagonimus sp. in the riverside area were 14.2% and 8.4%, respectively, which were significantly higher than those of the inland area (3.2% and 1.7%, respectively). The egg-positive rates of C. sinensis and Metagonimus sp. in males (16.7% and 10.0%) were significantly higher than those of females (3.5% and 1.8%). However, there were no significant differences of EPG values between localities and sexes. The prevalence of clonorchiasis and metagonimiasis in this survey was significantly lower than that in the previous reports. However, there is still a high prevalence of infection with C. sinensis and Metagonimus sp. in this region, especially in the riverside area.

The authors have experience of a case of prolonged paresis following administration of galamine triethiodide to a patient undergoing reoperation. The muscular weakness continued for 20 hours, necessitating artificial ventilation intermittently. It was reversed by neostigmine.
