Angiographic findings were analysed in 11 cases of Behcet'sdisease which was diagnosed clinically in Seoul national University Hospital from July 1982 to June 1983. Arterial involvement was noted in 5 cases and venous involvement in 6 cases respectively. Arterial aneurysm and occlusion were arteriographic findings. Arterial aneurysm was noted at large arteries in all 5 cases and multifocal involvement was noted in 4 cases. Characteristic finding of arterial involvement was protruding saccular aneurysm. Venous involvement was thrombotic occlusion of deep veins in iliac, femoral and tibial areas in all 6 cases. Behcet's disease should be differentiated whenever these arterial or venous angiographic findings are revealed in a young adult.

A 30-year-old male was involved in a car accident. Radiographs revealed a depressed marginal fracture of the medial tibial plateau and an avulsion fracture of the fibular head. Magnetic resonance imaging showed avulsion fracture of Gerdy's tubercle, injury to the posterior cruciate ligament (PCL), posterior horn of the medial meniscus, and the attachments of the lateral collateral ligament and the biceps femoris tendon. The depressed fracture of the medial tibial plateau was elevated and stabilized using a cannulated screw and washer. The injured lateral and posterolateral corner (PLC) structures were repaired and augmented by PLC reconstruction. However, the avulsion fracture of Gerdy's tubercle was not fixed because it was minimally displaced and the torn PCL was also not repaired or reconstructed. We present a unique case of pure varus injury to the knee joint. This case contributes to our understanding of the mechanism of knee injury and provides insight regarding appropriate treatment plans for this type of injury.

STATEMENT OF PROBLEM: One of common problems associated with single teeth dental implant prosthetic is the loosening of screws that retain the implants. PURPOSE: The maintenance of screw joint stability is considered a function of the preload achieved in the screw when the suggested initial tightening torque is applied. The purpose of this study was to investigate acquired preload after initial clamping torque for estimating screw joint stability. MATERIAL AND METHODS: A comparative study on the effect of initial clamping of two types of implant systems with different connections was conducted. Three dimensional non-linear finite element analysis is adopted to compare the characteristics of screw preloads and stress distributions between two different types of implant systems composed with abutment, screw, and fixture under the same loading and boundary conditions. RESULTS: 1. When the initial clamping torque of 32Ncm was applied to the implant systems, all types of implants generated the maximum effective stress at the first helix region of screw. 2. Morse taper connection types of implants generate lower stress distributions compared to those by butt joint connection types of implants due to large contact surface between abutment and fixture. 3. The internal types of implant systems with friction grip type implant systems have higher resistance to screw loosening than that of the external types of implant systems since the internal types of implant systems generated larger preload than that generated by the external types for the same tightening moments.

PURPOSE: Under the rising demand of health services, the critical pathway (CP) which standardizes the practice guideline was introduced as a means to provide quality healthcare service. CP may increase the patient's satisfaction rate by providing systematic and consistent service. We aimed to evaluate the significance of CP by development and application of CP to patients undergoing laparoscopic cholecystectomy. METHODS: From June 2010 to July 2011, 148 patients underwent elective laparoscopic cholecystectomy. Patients were divided into two groups, including 57 patients in the CP group and 91 patients in the non-CP group. In a retrospective review, related hospital costs were analyzed and compared for both groups. Survey results on satisfaction for the CP group were also analyzed. RESULTS: The mean age was 22.7 years in the CP group and 37.9 years in the non-CP group. Number of hospitalized days was one day for the CP group and 2.51 days for the Non-CP group with p<0.001. In cost analysis all variables showed a significant reduction in the CP group compared to the Non-CP group. The satisfaction rate in the CP group scored 8 points out of 10. CONCLUSION: Results have shown benefit from the financial point of the view for the CP group. Current inclusion criteria for CP are limited and still in development for a solid protocol. Further efforts with a large-scale comparative study to broaden the indication for CP are desired.

The formation of aortic thrombi is an extremely rare complication of acute pancreatitis. Here we report a case of acute pancreatitis complicated by a paraesophageal pseudocyst, necrotizing mediastinitis, and the formation of multiple thrombi in the ascending aorta. The patient was successfully treated by surgical therapy, which included extensive debridement of the mediastinum and removal of the aortic thrombi under cardiopulmonary bypass. Although esophageal resection was not carried out concomitantly, the lesions were resolved and the patient remained free of complications over 2 years of follow-up care.

PURPOSE: Recurrent patellar dislocation is often associated with genu valgum. The purpose of this study was to analyze the short-term results of single-incision, closing-wedge distal femoral osteotomy (CWDFO) combined with medial reefing and lateral release for recurrent patellar instability with genu valgum. MATERIALS AND METHODS: Combined CWDFO/medial reefing/lateral release was performed on 10 knees. Clinical evaluation was based on pre- and postoperative Knee Society Score (KSS) and Kujala patellofemoral score. Radiographic evaluation was performed with reference to the weight-bearing line (WBL), the femorotibial angle (FTA), and the mechanical lateral distal femoral angles in the knee-standing view. RESULTS: At a mean follow-up of 20±11.7 months (range, 12–42 months), KSS scores improved significantly, from 46.7±5.2 preoperatively to 87±4.4 postoperatively (p<0.001), as did the Kujala score, from 44±8 preoperatively to 86.6±6.8 postoperatively (p<0.001). The WBL decreased significantly, from 76±7% preoperatively to 41±11% postoperatively (p<0.001). The FTA was improved significantly, from 12.7±1.7° preoperatively to 4±4° postoperatively (p<0.001), as was the mLDFA, from 83±4° preoperatively to 91±1.3° postoperatively (p<0.001). CONCLUSION: Use of single-incision CWDFO combined with medial reefing and lateral release prevents patellar dislocation, corrects deformity, and improves clinical outcomes.

PURPOSE: Although obstructive jaundice is a rare presentation, it is an ominous sign of poor prognosis in patients with gastric cancer. Thus, we investigated the incidence, the clinical features, the pathologic characteristics, the treatment modality, and the prognosis for obstructive jaundice in patients with gastric cancer. METHODS: A retrospective analysis was done for patients with gastric cancer who had presented with obstructive jaundice at Korea University Guro Hospital from January 1988 to December 1998. RESULTS: During that period, 2546 patients were diagnosed with gastric cancer, and obstructive jaundice was revealed in 20 (0.78%). The mean age was 58 13 years, and the sex ratio (male:female) was 5.7:1. Jaundice was the first presentation in two patients, and it developed in the other 18 patients during the follow-up period after the initial operation or chemotherapy. The level of total bilirubin was 16.7 8.1 mg/dl, and the cause of the jaundice was lymph-node enlargement at the porta hepatis. A percutaneous transhepatic biliary drainage (PTBD) was done in 17 patients, and improvement was seen in 13 (76%). The most common site of the obstruction was common hepatic duct (CHD) (60%). Antrally located, moderately differentiated and Borrmann type-III gastric cancers were commonly associated with obstructive jaundice. The mean duration from jaundice to death was 4.6 6.2 month. CONCLUSION: Obstructive jaundice is very rare in patients with gastric cancer and is associated with poor survival. Although the bilirubin level was decreased by a PTBD, the survival was not improved. An extended lymphadenectomy along the hepatoduodenal ligament is necessary to prevent obstructive jaundice due to recurrence particularly, in patients with antrally located, moderately differentiated and Borrmann type-III carcinomas.
