Ankle arthrodesis has been used as standard treatment of ankle arthritis unresponsive to conservative treatment. Transfibular approach was used for ankles with severe deformities and minimally invasive arthroscopic ankle arthrodesis was used for patients with mild deformities. Anterior approach may be used when lateral approach couldn't be performed. Tibiotalocalcaneal arthrodesis is standard treatment for coexisting ankle and subtalar arthritis, and modified Blair arthrodesis can be used if the talus body resection is necessary in severe talar necrosis. In serious infection of ankle arthritis, arthrodesis can be performed as staged operation. In cases with low bone density and severe deformities, Charcot arthropathy should be considered.

Background: Although adjuvant chemotherapy is a standard treatment in stage III colon cancer, its benefit is not as clear for stage II patients. In this retrospective analysis, we aimed to evaluate the survival of patients with low-risk stage II colon cancer, the efficacy of adjuvant chemotherapy in high-risk stage II colon cancer patients, and prognostic factors in stage II disease. Materials and Methods: One hundred and seventeen patients who were diagnosed with stage II colon cancer between January 2006 and December 2011 were included in the study. Patients were stratified into two groups as being low-risk and high-risk according to risk factors for stage II disease. Adjuvant 5-fluorouracil-based chemotherapy were administered to the patients with risk factors. Results: Ninety-four patients were treated with adjuvant chemotherapy due to high risk factors and 23 were monitored without treatment. Median follow-up time was 43 months. In terms of disease free survival and overall survival, adjuvant chemotherapy did not provide a statistically significant difference. Univariate analysis demonstrated that bowel obstruction was the major risk factor for shortened disease-free survival, while bowel perforation and perineural invasion were both negative prognostic factors for overall survival. Conclusions: The recommendation of adjuvant chemotherapy for stage II colon cancer is not clear. In our study, it was found that adjuvant chemotherapy did not contribute to survival in high-risk stage II patients. Due to the fact that prognosis of stage II patients is good, many more patients will be needed for statistically significant differences in survival. Adjuvant chemotherapy containing 5 fluorouracil is being used to high-risk stage II patients although it is not a standard treatment approach.

Purpose: CA 19-9 need to examine a number of sample volume, and the postwar 200 U/ml concentration hook effect appears slight. Thus, the antibody-antigen reaction, and by reducing the amount of (sample volume), they can hook effect to minimize the impact of the sample volume and relevance know, I saw the hook effect. In addition, the current maximum of using the standard concentration of the reagent in 240 U/ml increase more than the standard concentration can be seen knows. Material and Method: 5 U/ml and under, make a few low concentration of serum pool from the high concentration of the sample hook effect together with a standard concentration of about 500 to meet the production. The reagents used in experiments are currently using SNUH NM experiment. Orignal method along with the experiment is to 25 ul sample volume (1 / 4), 50 ul (1 / 2), 100 ul (Orignal method) in the experiment. My greatest concentration of the reagent concentration of approximately two times the standard concentration of production. When was the last to make the first experiment, as measured by the standard concentration after that. The new inspection information through a standard solution modified by entering values in them. Results: 100 ul, and to apply the new standard concentration y = 1.3021x - 10.97, $R^2$ = 0.9844. Overall, the results showed a similar orignal method. Because of the concentration in the value of more than 240 U/ml, but it is an overall value that can be made out of a similar value When I put the 50 ul y = 1.045x + 9.5861, $R^2$ = 0.9428. Overall orignal method and the results of a similar value. 50 ul, and to apply the new standard concentration y=1.2006x+11.252, $R^2$=0.9423. Showing a slightly lower value compared with orignal method. Because of the concentration in the value of more than 240 U/ml, but it is an overall value that can be made out of a similar value. When I put the man 25 ul y=0.6012x+24.755, $R^2$=0.4033. Results showed that very small amounts of sample are insecure inside and showed a lower middle cpm orignal method and showed a lot of mismatched. Conclusions: 25 ul of the sample volume is not possible to use the instability had, when I put the 50 ul of the orignal method can be used to show a similar concentration. The new values are slightly lower concentration, The new values are slightly lower concentration, concentration, which are likely due to the lack of data has had a little gap between the sample showed 80 to 200 U/ml additional experiments seem to do. Apply a new 100 ul concentration values are applied to a large crowd is not even in sight. But this way the concentration of 100 to more 400 U/ml gather further experiments should possible adds.

Purpose: The purpose of this study was to investigate the extent of empowerment, task performance and job satisfaction perceived by hospital nurses and the relationship among those variables. Methods: The sample consisted of 261 nurses from a university affiliated hospital. Data were collected with self-administrated questionnaires including empowerment, performance and job satisfaction and analyzed using mean, standard deviation, ANOVA and $Scheff{\acute{e}}$ test. Results: The mean scores of variables were as follows. Empowerment was 4.6472, task performance was 3.7814, and job satisfaction was 3.1240. The older, more educated and more experienced nurses showed more empowered and higher job performed than the younger, less educated and less experienced nurses. Empowerment had a positive correlation with task performance and job satisfaction. Conclusions: The results imply that hospital should develop the empowerment program for nurses to be more job performed and satisfied.

Although the accounting system is a very useful information system for manager, that of the National University Hospitals is not settled until now. Specially, when it will adapt the responsibility management system itself, it will more important tools for them. The purpose of this research is to make the standard accounting system for National University Hospital. It was surveyed the 7 National University Hospital's accounting system, and compared to that of Private University Hospital. The results are fellows; First, it must be match financial report with budgeting system. By comparing to each other, it can make to evaluate the performance of hospital. Second, it must make same format and contents in financial report among 7 hospitals. Specially, the cost information is needed to be made more details. This research suggest the new direction to make the basic information form. It was confirmed with financial manager in private university hospital. We hope it will contribute to make the new accounting system for National University Hospital.

Gastric cancer is a major cause of cancer-related mortality. At the time of diagnosis, majority of the patients usually have unresectable or metastatic disease. The most common sites of metastases are the liver and the peritoneum, but in the advanced stages, there may be metastases to any region of the body. Bone marrow is an important metastatic site for solid tumors, and the prognosis in such cases is poor. In gastric cancer cases, bone marrow metastasis is usually observed in younger patients and in those with poorly differentiated tumors. Prognosis is worsened owing to the poor histomorphology as well as the occurrence of pancytopenia. The effect of standard chemotherapy is unknown, as survival is limited to a few weeks. This report aimed to evaluate 5 gastric cancer patients with bone marrow metastases to emphasize the importance of this condition.

The epidemic of 2019 novel coronavirus, later named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still gradually spreading worldwide. The nucleic acid test or genetic sequencing serves as the gold standard method for confirmation of infection, yet several recent studies have reported false-negative results of real-time reverse-transcriptase polymerase chain reaction (rRT-PCR). Here, we report two representative false-negative cases and discuss the supplementary role of clinical data with rRT-PCR, including laboratory examination results and computed tomography features. Coinfection with SARS-COV-2 and other viruses has been discussed as well.
