  • The usefulness and accuracy of computer-assisted surgery have been evaluated clinically in many orthopedic fields, such as, joint replacement arthroplasty, cruciate ligament reconstruction, and pedicle screw placemen. Recently several preliminary reports have been issued on the application of navigation to bone tumor surgery. The main advantage of navigation-assisted bone tumor surgery is that it provides highly accurate three-dimensional radiological information for intraoperative guidance. In particular, distances from tumors to resection margins can be precisely determined using intraoperative three-dimensional images. Accordingly, the technique allows preservation of function to be maximized by minimizing unnecessary resection. However, surgeons should recognize that the accuracies of navigation systems in bone tumor surgery have some hidden pitfalls. Here, based on our clinical results, we describe the surgical techniques used and include some cautionary notes.

  • Objective : To find a treatment strategy, this study aimed to review and compare the clinical studies of Korea, China, and Japan on traditional medicine treatment for Behcet's disease. Method : Literature searches were performed on six databases in each country and English databases, such as OASIS, KoreanTK, CNKI, J-STAGE, PubMed, and Cochrane CENTRAL. In addition, using the limited keywords, the area was restricted to traditional medicine treatment, but the period was not limited. Studies were categorized according to the study design and we analyzed the difference of treatment among three countries. Results : One hundred and forty-one clinical studies met our inclusion criteria: 11 studies in Korea, 15 in Japan, 115 in China. Randomized controlled trials (RCT) have increased in China, however, no RCT was reported in Korea and Japan. The method of treatment was mainly traditional herbal medicine in all the three countries, but there were significant differences in the field of syndrome identification and prescription among countries. The studies in China made use of most various treatment modalities and reported the highest effectiveness. Conclusion : Traditional medicine treatment showed a considerable effect for improving various symptoms of Behcet's disease. However, more research for answering the safety and well-designed studies considering characteristics of Behcet's disease should be performed to evaluate the effectiveness of traditional medicine treatment objectively in the future.

  • Purpose: We wanted to evalulate the clinical results of pectoris major tendon transfer for a neglected winged scapula that was caused by paralysis of the serratus anterior due to injury to the long thoracic nerve. Materials and Methods: A patient had neglected winged scapula that followed an arthroscopic operation for multi-directional instability of the shoulder joint, which was caused by traumatic dislocation. The patient was treated with pectoralis major tendon transfer using the modified Eden-Lange procedure. The range of a motion was improved from forward flexion $90^{\circ}$ and external rotation $70^{\circ}$ to $170^{\circ}$ and $150^{\circ}$ respectively. Results and Conclusion: There were no complications or recurrence and the patient's psychological satisfaction was also high. If the shoulder girdle muscles are intact, except for the serratus anterior, then pectoralis tendon transfer is a satisfactory method that can provide normal scapulo-thoracic motion.

  • In the field of clinical medicine and research, the analysis of such as protein and DNA at the molecular level and even at the cell level are necessary for disease diagnosis and treatment. In many cases, a real time image of samples is needed for the accurate analysis and manipulation of samples since experimental samples are degenerated with time. In this research, a three-dimensional fluorescence microscope device was developed for taking images of protein and DNA inside a single cell and the server-client based image analysis system was made for an integrated management of the real-time images taken from the microscope device. The system consists of a fluorescent measurement device, the associated software and a client program on smartphone. The developed system allows doctors or experimental managers to receive and look at the real-time experimental images taken from the samples of patients anywhere in the emergency, to analyze results and to instantly diagnose the disease and to transfer the results to the patients. As a result, the system is able to be utilized in the implementation of ubiquitous health as well.

  • Purpose: A traumatic lung cyst (TLC) is a rare complication and is usually detected with a pulmonary contusion. This study attempted to identify the prognostic factors and the clinical characteristics for pulmonary contusion with TLCs. Methods: We retrospectively reviewed the medical records and chest CT findings of 71 TLC patients who visited our hospital from January 2006 to December 2007. Patients were assessed for any clinical characteristics. We evaluated significant differences between the survival and the death groups for patients with a traumatic lung cyst. Results: The male-to-female ratio of patients with TLCs was 54:17, and the mean age of the patients was $37.70{\pm}19.78years$ with 36.6% of the patients being under 30 years fo age. The cause of blunt thoracic trauma was mainly pedestrian traffic accidents (26.8%) and falls (25.4%). Associated conditions included pulmonary contusion in 68 patients (95.7%), hemopneumothorax in 63 patients (88.7%), and rib fracture in 52 patitents (73.2%). There was no consistent relationship between the number of TLCs and the pulmonary contusion score. The overall mortality rate of TLC patients was 26.8%. Death correlated with a need for ventilatory assistance, mean arterial pressure, worst mean arterial pressure in 24 hours, initial pH and base excess, worst pH and base excess in 24 hours, refractory shock, initial GCS score, and pulmonary contusion score. Conclusion: The presence of the aforementioned predictors indicate serious injury, which is the main determinant of the outcome for thoracic injuries with TLCs.

  • Objectives : This study was aimed to review the trend of clinical studies in Journal of Oriental Neuropsychiatry since 2001 to 2010. Methods : We collected 260 clinical studies and analyzed them for publish year, sorts of disease or symptoms, pattern identification diagnosis, and classification of clinical studies. Among them, we selected 46 clinical experimental studies and these studies were further analyzed for publish year, research institution, sort of disease or symptoms, sorts of treatments, number of subject, and pattern identification diagnosis. Results : The number of clinical studies in Journal of Oriental Neuropsychiatry have increased since the year of 2001. There were 62 kinds of diseases and symptoms and Hwa-Byung had the highest number of studies followed by depression, headache, insomnia and so on. The clinical experimental studies, which took up 17% of the clinical studies, have increased since 2001 and was varied with year. There were 13 reserch institutions for clinical experimental studies and they studied about stress, dementia, Hwa-Byung, and so on. Most of studies researched treatment about acupuncture, herb medicine, and meditation treatment for persons under 144. There are only 22% of studies using pattern identification diagnosis. Conclusions : For the development of oriental medicine for psychiatric disease, we need more qualifying clinical studies like RCT. We hope more researchers for psychiatry disease of oriental medicine will be interested in the publication of clinical studies and this will serve to produce advance of oriental medicine as evidence based medecine.
