OBJECTIVE: CDA is a standard for the exchange and sharing of clinical documents among all entities in the healthcare domain. As it proliferates, the number of CDA documents will increase exponentially and it will require huge storage spaces to store them. The main goal of this study is to devise an efficient compression method optimized for CDA documents so that the storage requirement can be lowered. METHODS: The method proposed in this paper is based on a compression method called Xmill which has been designed specifically for XML documents at large, which requires human intervention for the effective compression, especially, of CDA. Our proposed method, CDACOM, automatically extracts type information from CDA documents to infer the data type, assigns data values of the same type to the same data container, and applies an optimized encoder to the container so that a better compression rate can be achieved. RESULTS: Experiments with various types of CDA documents were performed to evaluate the effectiveness of CDACOM over Xmill. The results show that CDACOM indeed outperforms Xmill and can decrease the output file size by about 24.1% on average, compared to Xmill. If documents are combined and compressed together, the gap gets even bigger to about 50%. CONCLUSION: The proposed compression method, CDACOM, is very effective and promising. It will help lowering the cost for systems to transmit and store CDA documents and, hence, expediting the adoption of the standard in the healthcare domain.

Isometric positioning of the ACL graft is an important consideration in successful reconstruction of the ACL-deficient knee. The purpose of this study is to get a certain guideline in the endoscopic one-tunnel technique of anterior cruciate ligament reconstruction by measuring the skin angle and determine the degree of minimum flexion of the knee joint during femoral tunneling and interference screw fixations. To get the guide lines, first we get the tibial tunnel angle parallel to the Blumensaat's line from fully extended lateral knee joint radiography. Secondly measure the differences between angles of the femur-tibia shaft and anterior thigh-leg skin. Then measure the minimum femur-tibia flexion angle does not perforated the posterior cortex of the distal femur during femoral tunneling. Intraoperative measuring the angle between interference screw guide pin and tibial tunnel to get the parallelism of the femoral tunnel and interference screw. The results were as follows; The average femur-tibia shaft angle with 30degrees anterior thigh-leg skin angle was 30.2+/-1.75degrees, with 45degrees was 45.2+/-1.23degrees, with 60degrees was 61.9+/-4.23degrees, with 75degrees was 78.6+/-2.62degrees, with 90degrees was 97.8+/-3.96degrees. Predetermined sagittal tibial tunnel vector on the 0degrees extension knee joint lateral radiographs were applied to the several knee joint dynamograms. The mean minimum flexion angle of the femur-tibia shaft that doesn't perforate the posterior cortex of the femur was 45+/-1.58degrees (male), 44.5+/-4.97degrees (female). The average angle between interference screw guide pin and tibial tunnel was 23.0+/-2.23degrees. The findings of the present study suggest that anterior thigh-leg skin angle can be used instead of the true femur-tibia shaft angle. Less knee flexion angle makes good arthroscopic view during the tibio-femoral tunneling and interference screw fixation.

We report herein a case of smooth muscle hamartoma associated with Beckers nevus in a 5-year-old female. The child presented with a slight.ly brownish. 2 x 3 cm sized, pigmentecl patch with follicular accentuation on the right forearm, witch had been observecl since age of 2. Histopathologic findings showed the epidermal changes most consistent with Becker's nevus and the presence of irregularly arranged hyperplastic smooth muscle hundless in the dermis.

Isolated dislocation of all five carpometacarpal joints is extremely rare, only eleven cases had been reported since 1873. In Korea, we have not seen it probably. We experienced one case of isolated dislocation of all five carpometacarpal joints with a good result in I year after closed reduction and internal fixation.
