BACKGROUND: Intussuseception is one of the most common diseases requiring abdominal emergency care in early childhood. The delay in diagnosis increases morbidity and, in particular, reduces the success rate of the non-surgical method of reduction. In this report, the authors determined the clinical characteristics of pediatric patients with intussusception, and the factors involved in delayed diagnosis and the efficacy of doppler ultrasonography in diagnosis. METHODS: The authors performed a retrospective study of 44 cases in 42 patients with intussusception who had visited the emergency room of SamSung medical center from January 1st to December 31, 1996. RESULTS: The sex ratio was equal and 64.3% of the patients were under 1 year of age. The prevalent complaints were vomiting(36.4%) and abdominal pain(33.8%). Ultrasonography was used in 11 cases, 3 of them were performed because of obscure symptoms and the rest were due to diagnostic delay. The average time past from visit to diagnosis was 4 hours and 20 minutes, and there were 4 diagnostic delays. Air enema reductions were unsucessful in 11 cases(25%) and that was related to hospital-visit delays and long time past from symptom onset to diagnosis. There were no motalities. CONCLUSION: To reduce delays in diagnosis and unnecessary operations, the use of doppler ultrasonography is recommanded in suspicious cases. And to reduce the hospital-visit delays, related to the failure on non-surgical reduction, the education about this disease is necessary.

We describe herein a case of meningioma showing three recurrences and in the end malignant transformation. To compare the differences of MIB1, p53 and progesterone receptor expressions in benign, recurrent and malignant meningiomas of the same patient, we performed immunohistochemical stainings for those markers. MIB1 and p53 reactivities were increased in proportion to histologic aggressiveness. By contrast, the progesterone receptor expression was noted in benign meningioma but not in malignant meningioma.

For many years, healing membranous bone fractures have been known to show a persistent lucency at the fracture interface. Radiographic follow-up has proven to be of little value as a guideline for healing of mandibular fractures. Recently, a fracture has been treated by rigid internal fixation by metallic plate and screws rather than closed reduction and wire fixation, we expected that some difference in the radiographic features of fracture healing. To investigate these questions we undertook a retrospective radiographic and clinical analysis of 33 followed patients with fractures of the body and angle of the mandible from 1993 to 1997. There were 26 male and 7 female patients ranging in age between 5 and 74 years, with an average of 29.7 years. All patients were managed by open reduction with metallic plates and screws. The length of follow-up ranged from 9 to 187 weeks. Total 81 radiographic follow-up films were obtained and divided into 3 grades according to the degree of radiolucency of fracture lines; grade 0 radiolucent fracture line and no evidence of fracture interface calcification, grade 1 decreased radiolucent area and evidence of fracture interface calcification, and grade 2 disappearance of fracture line.Until follow-up of 8 weeks, all of the radiographs showed grade 0. From 8 weeks to 16 weeks, 62.5 percent showed grade 0 and 37.5 percent showed grade 1. From 16 weeks to 48 weeks, 38.5 percent showed grade 1 and 61.5 percent showed grade 2. After follow-up of 48 weeks, all showed grade 2.In this study we have shown that the radiographic disappearance of mandibular fracture lines was usually accomplished by 48 weeks. We feel that radiographic union of the mandible is lagging well behind clinical union, but disapperance of the fracture line in rigidly fixated mandibular fracture was occurred earlier than healed by fibrous union. We propose that radiographic union of the mandible by approximately 1 year can be a guideline for the normal mandibular bone healing.

PURPOSE: The purpose of this study was to identify the influencing factors on turnover intention of nurses in long-term care hospitals. METHODS: Data were collected from 210 nurses in 11 long-term care hospitals in B city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and Stepwise multiple regression. RESULTS: Turnover intention was significantly correlated with emotional labor(r=.35, p<.001) and job involvement (r=-.38, p<.001). In a multiple regression, emotional labor (beta=.31, p<.001), age (beta=-.27, p<.001), job satisfaction (beta=.24, p<.001), job involvement (beta=-.23, p<.001), and number of patients assigned(beta=.14, p=.009) were associated with turnover intention. These factors attributed to 41.2% of the total variance in turnover intention. CONCLUSION: Considering the results of this study, proactive educational and/or human resource management interventions need to be developed especially for those younger nurses in order to reduce emotional labor as well as to promote job satisfaction and job involvement of nurses in long-term care hospitals.

PURPOSE: We studied the effectiveness and toxicities of 5-fluorouracil+leucovorin, combination chemotherapy in advanced or recurred colo-rectal cancer patients, who didn't have previous chemotherapy and enrolled from August 1993 to July 1998. MATERIALS AND METHODS: All patients were treated with leucovorin followed by 5-fluorouracil for 5 consecutive days every 4 weeks. Among 43 patients who were enrolled, 40 patients received treatment at least 2 courses, and they were evaluable. Male to female ratio was 21 to 19. In serum CEA level, 27 patients were greater than 5 ng/ml and 13 were less than 5 ng/ml. And primary site was colon in 21 patients and rectum in 19 patients. RESULTS: The complete response rate was 7,5% and the partial response rate was 25%. The median survival duration was 14.7 months, the median response duration was 16.0 months, and median time to progression was 7.3 months. In the analysis of response, survival duration, time to progression according to various characteristics of patients, serum CEA level and liver involvement were revealed significant difference in survival duration, time to progression (p=0.0122, 00350 & 0.0202, 0.0123) on univariate analysis, but no significant difference on multivariates. Hematologic and non-hematologic toxicities were mild and tolerable. CONCLUSION: This study indicates that the combination of 5-fluorouracil (370 mg/m) and leucovorin (20 mg/m) is effective and tolerable regimen in advanced or recurred colo-rectal cancer patients without previous chemotherapy.
