Objective: Predicting the incidence of emergency patients can be very important for the efficient use of emergency medical resources and the deployment of 119 centers in a pre-hospital setting. The study was conducted to analyze the occurrence of emergency patients using geographic information systems in a pre-hospital setting in Korea. Methods: The basic data used in this study were collected from the 119 centers in Chuncheon-si, Korea, under the firefighting headquarters in Gangwon-do from January 2012 to December 2016. Results: The total number of patients transferred by 119 paramedics was 72,362. Of these, 9,904 (14.7%) were emergency patients; 519 (0.7%) had cardiovascular diseases; 383 (0.5%) had cerebrovascular diseases; 3,043 (4.2%) were trauma patients; 58,413 (80.7%) were non-emergency patients. The occurrence of emergency diseases was slightly lower in the Hyoja-dong area, and it was slightly higher in the area of the outskirts of the city. The incidence of heart disease was low in the Hyoja-dong and Nam-myeon areas, but the incidence of heart disease was highly observed in other areas. The number of trauma patients was 1,265 (41.6%) in the outskirts of the city, a suburban area, showing a relatively higher incidence than other emerging diseases. Conclusion The deployment of ambulances in Chuncheon-si should be carried out considering demographic characteristics and patient occurrence.

The endodermal sinus tumor (EST) is the second most common form of malignant germ cell tumor of the ovary. It accounts for 22% of germ cell lesions and the median age of the patients is 19 years. Three fourths of the patients are initially seen with a combination of abdominal pain and abdominal or pelvic mass. Acute pain is caused by torsion of the tumor and the symptoms are acute and may lead to the diagnosis of acute appendicitis or a ruptured ectopic pregnancy. The tumor is usually large with most tumors measuring between 10 and 30 cm diameter. These neoplasms are highly malignant. In the past, these tumors were once almost uniformly fatal within 2 years of diagnosis, but recent advances in treating the EST of the ovary with the combination chemotherapy result in improvement of the prognosis. Management of younger patients with early stage ovarian EST who desire to preserve fertility can be a challenging problem, and treatment strategies which can save ovarian function must be considered. We have experienced three cases of endodermal sinus tumor in three women (Ic, 18 years; IIc, 20 years; Ic and right proximal femur metastasis, 21 years) and report them with eager review of literatures.

BACKGROUND: GenediaTM H. pylori ELISA is a newly developed diagnostic method which detects serum anti-H. pylori IgG antibody. The aim of this study was to assess the accuracy of GenediaTM H. pylori ELISA for the diagnosis of H. pylori infection in Korean population. METHODS: GenediaTM H. pylori ELISA and GAP-IgG were performed in 353 adult sera and Pyloriset-IgG EIA in 184 subjects. In children, 43 serum samples were tested with GenediaTM H. pylori ELISA. H. pylori infection was determined by rapid urease test, histology, culture or 13C-urea breath test in adults. In children, the subject was considered to be H. pylori positive if 13C-urea breath test was positive. RESULTS: In adults, the sensitivity and specificity of GenediaTM H. pylori ELISA were 93.2% and 83.5% with positive and negative predictive values of 85.1% and 92.5%. Those for GAP-IgG and Pyloriset-IgG EIA were 67.2%, 82.4%, 79.3%, 71.4% and 89.1%, 88.4%, 71.9%, 96.1%, respectively. In children, sensitivity, specificity, positive and negative predictive values of GenediaTM H. pylori ELISA were 80%, 84.8%, 61.5%, and 93.3%. Sensitivity and negative predictive value of GenediaTM H. pylori ELISA were significantly higher than those of GAP-IgG (93.2% vs. 67.2%; plt;0.005 and 92.5% vs 71.4%; p<0.005, respectively). CONCLUSION: GenediaTM H. pylori ELISA is a relatively accurate method for the serodiagnosis of H. pylori infection in Korean subjects compared to GAP-IgG. These results may suggest the clinical use of GenediaTM H. pylori ELISA for epidemiological studies of H. pylori infection in Korea.
