Although the incidence of tuberculosis of the bone and joints is being decreased with good nutrition, hygine and the development of preventive medicine, it is still a common disease in our clinic. One hundred and ninty-eight cases of tuberculosis of the bone and joints were studied in the Department of Orthopedic Surgery, Seoul National University Hospital for 10 years from January, 1966 to December. 1975. The results were as follows: 1. Total cases of tuberculosis of the bone and joints were 588 Among them, peripheral bone and joints excluding the spine occupied 198 cases (34%). 2. Sex ratio was 1.7 : 1 (male : female). Age distribution showed the group below 10 years was 78 cases (39%). On the other hand, 7 cases were over 51 years old. 3. More than 50% of patients visited hospital after one year from the onset. 4. One-third of all cases had been given some management before admission and the most common treatment was anti-tuberculous chemotherapy (25%). 5. Erythrocyte sedimentation rate was definitly increased in 41%. 6. Associated tuberculous lesionsoe of extraskeletal system were confirmed in 66 cases (33%). Among them, active pulmonary tuberculosis were 51 cases (77%) 7. Various treatments (conservative, curettage, synovectomy, arthrodesis, etc.) had been carried out. However, surgical managements for saving the range of motion must be considered always before arthrodesis.

Transmitral left ventricular diastolic inflow velocities determined by pulsed Doppler in 47 normotensives, 80 hypertensives and 44 age-matched hypertensives were measured to evaluate the effects of age and left ventricular hypertrophy on left ventricular diastolic fuction in normotensives and hypertensives. The results were as follows: 1) The peak E velocity in normotensives(77.82+/-13.53cm/sec) was significantly different from those of hyeprtensives(58.13+/-11.80cm, p<0.01) and age-matched hypertensives(59.31+/-10.94cm/sec, p<0.01). The peak E/A in normotensives(1.31+/-0.45) was significantly different from those of hypertensives(0.83+/-0.21,p<0.01) and age-matched hypertensives(0.83+/-0.20, p<0.01). 2)In normotensives, simple linear regression analysis revealed strong inverse correlations of peak E with age(r=-0.758, p<0.01), peak E/A with age(r=-0.748, p<0.01), but no significant correlation of peak E and peak E/A with LVMI(p>0.05). Stepwise regression analysis revealed that age was the most important correlate of peak E and peak E/A in normotensives(peak E: R

Fat embolism is one of a rare catastrophic complication after multiple fraetures and extensive soft tissue injury. Many hypothesis on its pathogenesis has been postulated by many writers, still its exact pathogenesis, definite diagnostic criteria and treatment is not established. Nowadays fat embolism is considered as a respiratory insufficiency syndrome, even disseminated intravascular coagulation rather than isolated phenomena after extensive trauma of musculoakeletal system. Respiratory failure associated with fat embolism is a major cause of death, but is usually seIf-limited and is responsive to intensive treatment. Monitoring of blood gas is required for early diagnosis and respiratory supportive treatment with continued monitoring is necessary until resolution. The writers experienced six cases of fat embolism, at the Department of Orthopedic Surgery, Seoul National University Hospital for the period of three years from June 1974 till May 1977. Respiratory support, parenteral steroid and low molecular weight dextran with other supportive measure was a mainstay of treatment. Of six cases, five was recovered without sequalae and one was expired four days after trauma.

Flowcytometry is a very important technique for the analysis of cell properties, with the advantages of simultaneous multiparameter analysis of large cell population in a short time. Recent advances in computer science and techniques in cell preparation and staining make it more valuable for the study of cell biology and its clinical application. This study was performed to establish the techniques of flowcytometry analysis of osteosarcoma cells, to evaluate the results of the characteristics of the DNA and specific cell cycle phase of osteosarcoma cells obtained by preparation of paraffin-embedded tissue blocks, and to analyze any possible difference between cell populations lacated apart from each other in the tumor mass for making a base for further clinical application. Paraffin-embedded tissue blocks were obtained from 10 cases of primary osteosarcoma, which had undergone amputation without chemotherapy or radiotherapy. Tissue blocks obtained from the most superficial and the deepest portions of the tumor mass from the skin surface were selected respectively in each cases. To evaluate the technique and results obtained, analysis of the whole sample were performed twice in a separate setting. Satisfactory DNA histogram was obtained from 14 of 20 tissue blocks, with the values of distribution in the specific cell cycle phases. DNA aneuploidy was found in 2 cases with a DNA index of 1.6 and 1.3, and no difference in DNA ploidy by the location in tumor mass. The S-phase and G2+M phase fraction were 13.2±8.5 and 6.2±3.1 respectively, reflecting the increased cell proliferation compared with normal cell population. There was no statistically significant difference of these values between superficial and deep portions, but the difference was 9.0±9.7 with a maximum of 26.6, much greater than the difference 3.3±3.6, between the first and second set of analysis. Flowcytometry is a very useful technique in the analysis of the DNA and cell cycle phase properties, and the characteristics of DNA and cell proliferation status of osteosarcoma cells were successfully evaluated by this technique. Unsatisfactory DNA histograms were thought to be the result of inappropriate samples. To adequately evaluate the changes in the tumor mass, standardization in obtaining tumor tissue about the location in the tumor mass is suggested for future studies with flowcytometry about the properties of tumor cells.

Of the bronchographic findings of 408 patients, performed in our hospital for recent 5 years, 108 cases showed definite bronchial obstruction, and 61 cases of those were selected and their obstructive findings were evaluated. All that not confirmed were abandoned. For evaluation of the reliability of 9 bronchographic obstruction signs onappplying to diagnose malignant or benign pulmonary diseases, each sign was identified and applied to each of the61 confirmed cases. In addition, obstructed bronchi, distance of obstruction from the bifurcation site, and thedirection of meniscus, if peresent, were evaluated. The reuslts were follows; 1. The most frequent cause ofbronchial obstruction was lung cancer (59.0%), and that of the benign obstruction was pulmonary tuberculosis(13.1%). 2. Amputation, asymmetric narrowing, thumbprint indentation, rat-tail narrowing and encasement signs werethe most accurate signs of malignancy and were practically diagnostic ones, 3, The most frequent sign in lungcancer was sharp cut off one, but it could be seen in lung abscess and in unresolved pneumonia, too. 4. Circumferential symmetric narrowing and regular concavity with a small central profection signs were specific onesto benignancy. 5. The most frequent obstruction sign in benign lung disease was gradual tapering sign, but it alsocould be seen inbronchogenic epidermoid and alveolar cell carcinoma. 6. Of all bronchial obstructions, 55.4% occurred at lobar bronchus and 77.4% of those were caused by lung cancer. 7. 77.2% of those obstruction which located within 3 times distance of the bronchial diameter at the nearest proximal bifurcation site, were lungcancer, but 75.0% of those located at over 3 times distance were benign pulmonary diseases. 8. There were nocorrelation of the direction of the meniscus at the obstructing and in differential diagnosis between benign andmalignant pulmonary diseases.

BACKGROUND: Intramuscular stimulation (IMS) shows good results in the treatment of chronic pain patients who did not respond to other treatments such as oral analgesics, trigger point injection, nerve block and epidural steroid injection. Fluoroscopy Guided Interventional Musculoskeletal Adhesiolysis and Nerve Stimulation (FIMS) was used to stimulate the correct anatomic point using fluoroscopy. We present the results of FIMS in spinal stenosis. METHODS: 106 patients with ages ranging from 39 to 87 years were enrolled in this study. All the patients were postoperatively evaluated for the clinical outcomes such as numeric rating scale (NRS) for pain at 1 month, reduction in the analgesics dose, and the overall satisfaction rate. The patients considered to have received clinical benefit from FIMS were evaluated for the recurrence of pain by either a follow-up or telephone interview. RESULTS: FIMS reduced the level of pain compared with the pretreatment (P < 0.001). In addition, 61% of patients reported that they were satisfied. There were no procedural related serious complications. Three months after FIMS, there was continuing pain relief in 50% of the patients treated successfully. CONCLUSIONS: FIMS is a safe and effective treatment modality for spinal stenosis.

PURPOSE: The purpose of this study was to develop an instrument of task performance evaluation for clinical nurses, thus testing the validity and the reliability of the scale. METHOD: Data was collected from 84 Head Nurses and 255 General Nurses. A conceptual framework, composed of 4 factors of meaning in task performance evaluation, was identified through review of the relevant literature. A total of 78 items were developed and were used on a five-point likert scale. Through factor analysis, items whose factor loading was below 0.50 were deleted, thus 35 items remained. To test the validity and reliability of the instrument, the SPSS 11.0 windows program was used. RESULT: The results of the factor analysis indicated that 4 factors were classified and the cumulative percent of variance was 67.54%. The results of the reliability test indicated that Cronbach's coefficient of the total 35 items was over 0.9176. The results of the factor analysis indicated that factor loadings of all items was over 0.50. Conclusively, the validity and the reliability of the scale were proven. CONCLUSION: This study was identified as a tool with a high degree of reliability and validity.
