Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life, but it is rare in the pleura. We recently experienced a case of cytology of malignant fibrous histiocytoma in pleural fluid. The smear revealed histiocytic malignant cells, spindle malignant cells and inflammatory cells. The histiocytic cells showed abundant, pale cytoplasm and ovoid, irregular, eccentrically-placed nuclei. The spindle cells showed elongated nuclei. Intercellular collagen was also present.

Between January 1994 and February 1996 lumbar fusion was carried out in eight patients who had degenerative lumbar disease by a technique of translaminar facet screw fixation. The goal of instrumentation is to confer immediate stability to unstable segments and lower the pseudarthrosis rate. However, transpedicular systems can carry a risk of neural damage and require a high standard surgical skills. Therefore, the purpose of this study was to determine the efficacy and safety, and to introduce the simple fusion technique. We usually used this technique for the patients who had been planned single level fusion without definite preoperative instability. Preoperative diagnosis were isthmic spondylolisthesis in one, spinal stenosis in three and laterally herniated lumbar discs in four in which postoperative instability was expected without performing fusion. A single-level fusion was perfomed in all patients. Fusion levels were L2-3 in two, L3-4 in one, L4-5 in four and L5-Sl in one. The average follow-up period was 20 months, ranging from 12 to 36 months. Overall clinical satisfaction including excellent and good result was obtained in all cases. The fusion rate was evaluated radiographically and all were solidly fused. The time to fusion ranged from 3 to 10 months at an average of 5.4 months. There were no significant complications including nerve root injury, and screw loosening or breakage. Although this study was retrospective and the number of cases were small, translaminar facet screw fixation for degenerative lumbar disease is simple and readily available, and provides sufficient rigid stabilization.

10 cases of femoral shaft fractures were treated by cast brace during the past 5 years from May, 1975 to August, 1979 at the Department of Orthopedic Surgery, Korea General and Jae II Hospital, The results were summarized as follows; 1. Of the 10 cases, 8 cases were male and 2 were female, and age distribution was between 14 and 65. 2. 5 cases were treated by cast brace from the start as the primary treatment and the other 5 were by other method initially and followed by cast brace secondarily. 3. One of 5 cases treated by early cast brace developed delayed union and the other one of 5 cases treated by late cast brace secondarily developed non-union, which were treated by open reduction and internal fixation with cancellous bone graft. 4. The cast brace was applied within the first 6 weeks after fracture and average application time was 9. 7 weeks in the cases treated by early cast brace, which was compared with 12.5 weeks in the late cast brace group. 5. Average time of fracture healing was 13.5 weeks in the early cast brace group and 18. 5 weeks in the late cast brace group. 6. In three of 10 cases, counter traction was applied to reduce the limb shortening during bed rest.

Background: Esmolol as a drug for induced hypotension can, not only avoid many drawbacks of nitroprusside, but reduce the amount of intraoperative bleeding and make better operative field. This study was performed to evalute cardiovascular changes during esmolol-induced controlled hypotension. Methods: Induced hypotension using esmolol was applied to 18 adult patients receiving spinal surgery under the diagnosis of spinal stenosis or scoliosis. After prehydraion of 2,000 ml of crystalloid solution, 0.5 mg/kg esmolol was used as loading dose once, twice or three times until mean blood pressure (MBP) fell below 70 mmHg, followed by continuous infusion (50~300 microg/kg/min) of esmolol. MBP and heart rate (HR) were measured before, 5, 10, 15, 30, 60 and 90 min after esmolol administration, and 5, 10 and 15 minutes after discontinuation of esmolol. In 8 patients, cardiac output (CO) and mixed venous oxygen tension and saturation were measured before, during and after esmolol use. Results: MBP was decreased from 91+/-12 mmHg to 67+/-7 mmHg after 15 min (P<0.05). HR(BPM) was decreased from 76+/-17 to about 60 after 15 min (P<0.05). CO was decreased about 30% during induced hypotension but recoverd to initial level 15 min after esmolol discontinuation. While oxygen transport was reduced significantly during induced hypotension (P<0.05), oxygen consumption was maintained all the time. Conclusion: With the use of esmolol, stable hypotension could be achieved. Although oxygen transport decreased possibly due to reduction of CO, but oxygen consumption was maintained.

PURPOSE: Tumor necrosis factor-alpha(TNF-alpha) is a pro-inflammatory cytokine that has been implicated in the pathogenesis of cardiovascular disease. Serum levels of TNF-alpha are elevated in many human cardiac related pathogenic conditions, including heart failure. It is well known that TNF-alpha inhibits myocardial contractility and induces apoptosis of adult rat cardiomyocytes via stimulation of TNF receptor 1. But pathophysiologically relevant low levels of TNF-alpha can not induce apoptosis of neonatal cardiomyocytes. So, we evaluated the effects of different concentrations of TNF-alpha in cultured rat neonatal cardiomyocytes : apoptosis or necrosis. METHODS: Neonatal ventricular myocytes were isolated from 3-day-old rats by stepwise collagenase dissociation, and the cells were cultured for 3 days. After that, cardiomyocytes were treated with low(25 ng/mL) and high(250 ng/mL) concentration of TNF-alpha for 48 hours. Apoptosis was determined by terminal deoxynucleotidyl transfer-mediated end labelling(TUNEL) staining, and cell viability was evaluated by lactate dehydrogenase(LDH) measurements using cell culture supernatants. RESULTS: Low dose TNF-alpha did not induce apoptosis compared with controls(10.5 +/- 3.5% : 10.4 +/- 4.3%). And high dose TNF-alpha also did not induce significant apoptosis(10.2 +/- 3.6% : 10.4 +/- 4.3%). There was no detectable morphological changes of cardiomyocytes after low and high concentration of TNF-alpha treatment. LDH levels after TNF-alpha treatment was not significant compared with control(control : low : high, 3.2 +/- 0.1% : 3.1 +/- 0.2% : 3.3 +/- 0.3%). CONCLUSIONS: Our results suggest that high concentration of TNF-alpha alone can not induce apoptosis and significant cytotoxicity in neonatal rat cardiomyocytes.

Xanthogranuloma (XG) is a benign self-healing disorder that's characterized by multiple yellowish papulonodular lesions of the skin and other visceral organs. It appears within the first year of life in approximately 80 percent of the cases and it disappears spontaneously within 3 to 6 years. Adult XG clinically differs from juvenile XG in that the adult lesion is usually solitary, it generally does not involve internal organs and it does not resolve spontaneously. Multiple adult XG is classified as the presence of more than 5 XG lesions. A review of the literature shows that its disseminated form is exceptional, and only a few cases have been reported so far. We herein report on an atypical case ofadult XG with numerous papulonodular lesions.
