PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

Benign symmetric lipomatosis is characterised by diffuse symmetric deposits of adipose tissue, predominantly on the neck, shoulder, back and upper extremities. We report a case of benign symmetric lipomatosis in a 61-year-old-man, which was first noted one year previously. It began growing rapidly about 3 months ago and was associated with alcoholic liver disease. Histopathological findings showed that the reticular dermis had been replaced by normal uncapsulated mature fat cells that were slightly increased in number in the fibrous connective tissue. He was treated with theophylline 300mg/day for two months.

In patients disabled by severe rheumatoid and degenerative arthritis of both knees, bilateral total knee arthroplasty(TKA) afforded much functional improvement in pain relief and function. Postoperative results of bilateral TKA was described as being similiar to those observed among patients with single joint replacement. The purpose of this study is to evaluate the etiology and postoperative result of bilateral TKA performed on 32 knees in 16 patients at Department of Orthopedic Surgery, Seoul National University Hospital from Mar. 1985 to Oct. 1988. In our series, there were 15 females and only 1 male, their mean age was 53 years. Duration of follow up was ranged from 1 to 4 years and 5 months being average 1 year and 6 months. The results were as follow. 1. Cheif complaints were pain in 18 cases(100%) and difficulty in walking in 15 cases(82%). 2. Preoperative etiology was rheumatoid arthritis in 11 cases and degenerative arthritis in 7 cases. 3. Knee joint function by HSS(Hospital for Special Surgery) knee rating score was increased from 44.6 points preoperatively to 81.2 points postoperatively. 4. The tibiofemoral angle was changed from 1.4 degree varus to 4 degree valgus. 5. The prothesis type used were PFG(Press Fit Condylar) in 22 knees, Miller-Galante in 8 knees, AMK in 3 knees, PCA in 2 knees and unicompartmental type in 1 knee. 6. Complication were 1 case of knee fusion due to concomittant tuberculous arthritis and mild joint effusion in 6 knees. 7. Bilateral one-stage arthroplasty may be considered as an alternative procedure.

Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in the synovial membrane, periarticular structures, skeletal muscle and perineural sheath. Eventually, the joints are destroyed, ankylosed and deformed. Therfore, the aim of treatment is to keep the inflammatory process at a minimum, thereby preserving the joint motion, maintaining the health of muscle supplying motor power about the joint and preventing secondary joint stiffness and deformity. Surgical treatment in rheumatoid arthritis has progressed and there have been advances in the relief of pain and increase in the range of motion. Among them the results of total knee arthroplasty (TKA) have improved steadily during the past decade due to refinements in design, fixation, and surgical technique. At orthopedic department of seoul national university hospital, we performed 31 total knee replacement in 18 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1988. Following results were obtained. 1. Knee score increased from 37.8 to 76.9. 2. Tibio-femoral angle was corrected from 0.9° valgus to 5.3° valgus. 3. Conplications were peroneal nerve palsy in 3 knees, instability in 1 knee, tuberculous arthritis in 1 knee. 4. In 25 out of 31 knees, good functional results were obtained.

BACKGROUND: Although an ultrasound-guided brachial plexus block has become the standard, conventional brachial plexus blocks with a paresthesia or muscle twitch are still performed. However despite eliciting a paresthesia or muscle twitch, there are some cases in whom the brachial plexus block fails. This has been attributed to the difference between the proximal response (PR) and distal response (DR). Therefore, this study compared a supraclavicular block showing a PR with that showing a DR. In addition, clinical data such as success rate, onset time, and complications were examined. METHODS: Eighty three patients received a supraclavicular block with a nerve stimulator. All blocks were performed with 1% mepivacaine 40 ml. The subjects were divided into two groups-Group PR (n = 20, contraction of triceps or biceps) and Group DR (n = 63, flexion or extension of wrist or fingers) according to the types of muscle twitch. The success rate, onset time, and complications were measured and evaluated. RESULTS: The success rate of Group DR (93.7%) was higher than that of Group PR (75.0%) (P < 0.05). The onset times of Group PR and DR were 15.3 +/- 6.7 min and 14.4 +/- 6.0 min, respectively. CONCLUSIONS: The elicitation of a DR was more effective in increasing the success rate and reducing the onset time than the elicitation of a PR in a single-injection supraclavicular block.

The Third International Consensus Definitions for Sepsis and Septic Shock (SEPSIS-3) task force assessed the latest pathophysiological parameters associated with sepsis and septic shock and defined sepsis as life-threatening organ dysfunction caused by a dysregulated host response to infection. This SEPSIS-3 definition may be applied using relevant clinical and biological criteria including changes in the Sequential Organ Failure Assessment score and serum lactate levels. The new definition does not include criteria for systemic inflammatory response syndrome or the concept of 'severe sepsis.' The SEPSIS-3 definition aims to devise more precise descriptions of sepsis and to improve clinical care. However, there are important questions relating to the clinical application of the new definition. We review the main characteristics and limitations of previous definitions and discuss some of the potential controversies raised by the new framework.

BACKGROUND: Multiple needle attempts to gain a muscle twitch or a paresthesia for a classical supraclavicular brachial plexus block can increase the risks of nerve damage or pain. The aims of this study were to obtain reliable clinical data on ultrasound-guided supraclavicular blocks, demonstrate the higher success rate and fewer complications, and design an injection method for patients whose brachial plexus can not be located. METHODS: 105 patients received an ultrasound-guided supraclavicular block. 40 ml of 1% mepivacaine was injected without a muscle twitch or paresthesia. The groups were divided into two groups - Group A (n = 92, patients who had visible brachial plexus) and Group B (n = 13, patients whose brachial plexus can't be located). After the blocks, the clinical characteristics such as the success rate, the time to onset, the extent of the sensory block, and occurrence of complications were evaluated. RESULTS: The Success rate of Group A (98.9%) was higher than that of Group B (84.6%) (P < 0.05). The overall success rate was 97.1%. All patients could be operated on under sedation. The time to onset of Group A (12.6 +/- 4.4 min) was shorter than that in Group B (23.1 +/- 5.1 min) (P < 0.05). The overall time to onset was 13.8 +/- 5.5 min. There were no serious complications such as pneumothorax. CONCLUSIONS: An ultrasound-guided supraclavicular block is very effective in even patients whose brachial plexus can not be located.
