PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

In 1971 inclusion body myositis was reported by Yunis and Samaha. This disease is similar with chronic multiple myositis clinically. Pathologically, inclusion body myositis is characterized by intracytoplasmic vacuole with degenerating fibers and accompanied with inclusion body in internal nucleus and cytoplasm. Since then 240 cases of inclusion body myositis have been reported in the world including 3 cases in Korea. A 27 years-old lady had inclusion body myositis, which show slowly progressive muscular weakness. We confirmed this with clinical symptom, muscle biopsy, and electrophysiologic study. We report the typical manifestation of inclusion body myositis in a 27 years-old lady with the brief review of literature.

Purpose: Surgery is prioritized for a splenic injury when the patient is hemodynamically unstable or the injury is severe and there is an increased risk of bleeding. This study aimed to examine the outcomes of splenectomies where a surgical stapling device was used to reduce operation time and rapidly control bleeding. Methods: This retrospective study included 53 patients who underwent a splenectomy for traumatic splenic injury at Chosun University Hospital between 2012 and 2017. Clinical outcomes including operation time (duration), blood transfusion amount (number of units), length of hospital stay, length of intensive care unit stay, and mortality rate were compared between patients who received conventional ligation [conventional group (CG)] and patients who received a splenectomy where a surgical stapling device was used [stapling group (SG)]. Results: The SG showed an average operation time of 17 minutes less than the CG, although the reduction was not statistically significant. No significant differences in estimated blood loss and blood transfusion amount were determined between the 2 groups, although the SG received 1 more unit of red blood cells for transfusion in the 48-hour post-operative period compared with the CG. One case of pancreatic fistula as a postoperative complication was reported in the SG. Conclusion The use of a surgical stapling device in a splenectomy may be considered for a hemodynamically unstable patient with splenic injury which caused severe anatomical damage.

BACKGROUND: Lifestyle is an important risk factor for many diseases. We need to educate medical students for advocating health promoting behaviors to their patients. Teaching knowledge, however, was not enough for medical students to change their health-related lifestyle. In this study, we investigated health promoting behaviors of medical students, and the improvement of their health behaviors after competitive lifestyle modification program. METHODS: All sophomores of medical college in Seoul National University were included in this study. We performed lifestyle modification program consisting of lecture, group competition, and feedback. We focused on reforming health behaviors like smoking, drinking, exercise, stress management and eating habits. And we also checked common symptoms of functional diseases, medication frequency for relieving these symptoms and general life satisfaction. RESULTS: After 2 months of lifestyle modification program, the obese (P = 0.0455) and the average value of BMI (P < 0.001) were decreased and two of smokers quitted smoking. Numbers of medical students with health related habits such as regular exerciser (P = 0.027), frequent user of symptom-relief medication (P < 0.001), breakfast skipper (P = 0.005) were signifi cantly changed in positive way, and the average value of general life satisfaction score (P = 0.003) was improved. CONCLUSION: Lifestyle modification program improved medical students' health habits and enhanced general life satisfaction.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and cystic changes are commonly observed. However, there have been few reports of cases of exophytic pedunculated GIST with cystic changes. Here, we report a 45-year-old man who presented with a palpable mass in the left upper quadrant of the abdomen. The mucosal folds were endoscopically abnormal, but there was no mucosal lesion. Computed tomography demonstrated a large, low-density cystic lesion surrounding an enhanced nodule in the greater curvature of the gastric body, and there was no tumor infiltration to other organs. The patient underwent hemigastrectomy and the lesion was shown to be an exophytic pedunculated cystic tumor. Histopathological examination showed epithelioid cells with marked hemorrhaging. Immunohistochemical examination indicated that most of the tumor cell cytoplasm was positive for the c-kit protein (CD117) and CD34. The tumor was diagnosed as an exophytic pedunculated GIST of the stomach with cystic changes.

PURPOSE: For fixation of the large posterior malleolar fracture fragment, indirect anterior fixation with cannulated screw has been widely used, but the anatomical reduction is not always obtained. The purpose of this article is to evaluate the clinical result of posterior malleolar fractures treated with anatomical reduction and internal fixation using posterior approach. MATERIALS AND METHODS: We have analyzed the 15 patients with posterior malleolar fractures, treated with posterior approach from August 2005 to August 2008. The mean follow up period was 17.6 months, We have reviewed the perioperative joint integrity, method of operation, postoperative care, bony union and complication. A clinical outcome was evaluated by AOFAS (American orthopedic foot and ankle society) scaling system and Olerud & Molander scoring system. RESULTS: Among 15 cases, posterolateral approach and posteromedial approach were chosen in 9 cases and 6 cases respectively. The radiologic unions were achieved at 12.4 (12~18) weeks. Mean AOFAS score was 90.3 (72~98), and Olerud & Molander score was "excellent" in 5 cases, "good" in 7 cases, "fair" in 1 case and "poor" in 2 cases. Postoperative complications in 2 cases revealed a posttraumatic arthritis and a scar band contracture respectively. CONCLUSION: In posterior malleolar fracture of ankle joint, the integrity of joint has closely affected clinical outcomes. We suggest that a posterior approach for posterior malleolar fracture with especially incarcerated fragments and comminuted fractures, can be a useful method for anatomical reduction and stable fixation, and satisfactory clinical results.

Glomus tumors are uncommon soft tissue tumors which usually found in a subungual lesion of hand, producing pain. This uncommon tumors have been reported in other locations, including nasal cavity, stomach, mediastinum, heart, lung, and vagina etc. Especially, it was a very rare case found in an extradigital lesion of foot. Glomus tumors should not be ruled out for an extradigital mass lesion of foot and also any other locations. Although glomus tumors are generally considered a benign lesion, it should be considered that glomus tumors have also reported as a malignant type tumor, even the diagnosis based on histologic features not clinical one.

OBJECTIVE: To investigate the effect of treadmill aerobic exercise for eight weeks on cardiopulmonary fitness and functional mobility in stroke patients METHOD: Twenty one stroke patients who could walk independently and had MMSE score of 24 or higher were included. We used maximal exercise test by means of modified Harbor protocol before and after eight weeks' treadmill aerobic exercise. We monitored patients' status with EKG, heart rate, blood pressure and Borg rating of perceived exertion, and measured maximal O2 consumption, maximal heart rate, blood pressure, minute ventilation, rate pressure product and respiratory exchange ratio during maximal exercise test. We also assessed functional mobility by Fugl-Meyer assessment of lower extremity, Berg balance scale, five times sit to stand test, timed up & go test, dynamic gait index scale, activities-specific balance confidence scale and Korean-modified Barthel index before and after 8 weeks' training. RESULTS: Twenty one patients completed treadmill aerobic exercise training. After eight weeks' treadmill aerobic exercise, the cardiopulmonary fitness, measured by maximal O2 consumption, maximal heart rate, minute ventilation, systolic blood pressure, functional mobility measured by Fugl-Meyer assessment of lower extremity, Berg balance scale, five times sit to stand test, timed up & go test, dynamic gait index scale, activities-specific balance confidence scale and Korean-modified Barthel index showed statistically significant improvement (p<0.05). CONCLUSION: Eight weeks' treadmill aerobic exercise improved the cardiopulmonary fitness and functional mobility in ambulatory stroke patients.
