BACKGROUND: We investigated the risk factors for the recurrence of anterior shoulder instability after arthroscopic surgery with suture anchors and the clinical outcomes after reoperation. METHODS: A total of 281 patients (February 2001 to December 2012) were enrolled into our study, and postoperative subluxation and dislocation were considered as recurrence of the condition. We analyzed radiologic results and functional outcome including the American Shoulder and Elbow Surgeons Evaluation Form, the Korean Shoulder Society Score, and the Rowe scores. RESULTS: Of the 281 patients, instability recurred in 51 patients (18.1%). Sixteen out of 51 patients (31.4%) received a reoperation. In terms of the functional outcome, we found that the intact group, comprising patients without recurrence, had a significantly better functional outcome than those in the recurrent group. The size of glenoid defect at the time of initial surgery significantly differed between intact and recurrent group (p<0.05). We found that the number of dislocations, the time from the initial presentation of symptoms to surgery, and the number of anchor points significantly differed between initial operation and revision group (p<0.05). The functional outcome after revision surgery was comparable to intact group after initial operation. CONCLUSIONS: Eighteen percent of recurrence occurred after arthroscopic instability surgery, and 5.6% received reoperation surgery. Risk factors for recurrence was the initial size of glenoid defect. In cases of revision surgery, good clinical outcomes could be achieved using additional suture anchor.

PURPOSE: Human adipose tissue-derived mesenchymal stem cells(hATSCs) can be differentiated into multiple mesenchymal lineages, including bone, cartilage, and muscle. And growth hormone play important roles in the normal growth and development of the CNS. In this study, we explored whether the transplanted hATSCs and growth hormones could improve functional recoveries from rats with contusive spinal cord injury. METHODS: We divided 30 female rats, which were subjected to a weight driven implant spinal cord injury, into 3 groups with 10 rats each; Group A as a control group, group B with hATSCs transplantation on injured region, and group C with hATSCs transplantation and GH administration for 7 days. Then, we researched their neurologic functional recoveries before and 2, 4, and 8 weeks after transplantation using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. And we checked Y- chromosome positive cells by FISH(Fluorescent in situ hybridization) to identify the survival of transplanted mesenchymal stem cells. RESULTS: After 4 weeks of transplantation, the group B and group C showed significant improvement of neurologic function on BBB locomotor rating scale in comparison with the group A(Group A: 13.1+/-0.58, Group B: 14.6+/-0.69, Group C: 14.9+/-0.56). Moreover, the group C displayed meaningful recovery of neurologic function after 8 weeks in comparison with group B (Group B: 15.7+/-0.63, Group C: 16.5+/-1.14). The group A, the control one, improved for 5 weeks after injury, and had no more recovery. On the other hand, Group B and C showed the improvement of neurologic function continuously for 9 weeks after injury. CONCLUSION: In this study, we found out that hATSCs transplantation have an effect on neurologic functional recovery of spinal cord injured rat and GH injection seems to bring the synergistic results on this good tendency.

Cutaneous leishmaniasis is usually a self-limited infection of skin caused by the genus Leishmania, transmitted by a sandfly. This disease is endemic in tropical and subtropical zone, but recently several cases of cutaneous leishmaniasis were reported in Korean who had worked in Middle East. We report a case of cutaneous leishmaniasis in a 24-year-old male patient, who had travelled in Africa.

PURPOSE: To adapt to rapid and turbulent changes in the field of medicine, education, and society, medical school faculties need appropriate leadership. To develop leadership competencies through education, coaching, and mentoring, we need a leadership competency model. The purpose of this study was to develop a new leadership competency model that is suitable for medical school faculties in Korea. METHODS: To collect behavioral episodes with regard to leadership, we interviewed 54 subjects (faculties, residents, nurses) and surveyed 41 faculties with open-ended questionnaires. We classified the behavioral episodes based on Quinn and Cameron's leadership competency model and developed a Likert scale questionnaire to perform a confirmatory factor analysis. Two hundred seven medical school faculties responded to the questionnaire. RESULTS: The competency clusters that were identified by factor analysis were professionalism, citizenship, leadership, and membership to an organization. Accordingly, each cluster was linked with a dimension: self, society, team (that he/she is leading), and organization (to which he/she belongs). The clusters of competencies were: professional ability, ethics/morality, self-management, self-development, and passion; public interest, networking, social participation, and active service; motivating, caring, promoting teamwork, nurturing, conflict management, directing, performance management, and systems thinking; organizational orientation, collaboration, voluntary participation, and cost-benefit orientation. CONCLUSION: This competency model that fits medical school faculties in Korea can be used to design and develop selection plans, education programs, feedback tools, diagnostic evaluation tools, and career plan support programs.
