In general, soft tissue and bone tumors are diagnosed clinically by physical findings, laboratory data, and X-ray findings with only limited reliability, and a definite diagnosis must be supported by histopathological evidence. For this purpose, open biopsy routinely has been carried out, but there have been many disadvantages and sometimes followed by surgical complications. The present study was undertaken to compare the cytologic findings of soft tissue and bone lesions with the histological findings. The specimen were obtained by fine needle aspiration and Franklin-Silverman needle. For cytodiagnosis Stormby's cell block of aspirates were utilized. For histological diagnosis small tissue fragments obtained by the Franklin-Silvermans cutting needle were used. Then, the diagnostic accuracy of 3 different methods were compared, and the clinical applicability of those methods as adjunctive diagnostic procedures in the diagnosis of the soft tissue and bone tumors were assessed. The results obtained were as follows: l. In 15 out of the 20 cases (75%) in which clinically and roentgenologically the soft tissue and bone tumors were suspected, sufficient material was aspirated to enable detailed cytological diagnosis possible by fine needle aspiration. ln 13 out of the 15 cases, diagnosis could be made by cytologic findings, which was similar to histologic findings of tissue obtained by Franklin-Silverman needle. 2. In 6 out of the 20 cases, sufficient tissue fluid for cell block preparation were obtained from the tumor tissues. In 5 cases, cytologic findings of cell blocks were consistent with that ot the tissue obtained by Silverman needle. But in one case malignancy was susupected by cytodiagnostic method, and definite diagnosis could not be made. Finally the lesion was found to be malignant schwannoma through the histological study of tissue specimen obtained by Franklin-Silverman needle biopsy. 3. In 19 out of the 20 cases, diagnosis could be made by Franklin-Silverman needle biopsy. 4. Diagnostic accuracy of the lesions by clinical and roentgenological method was 75%, which overall diagnostic accuracy of 3 methods were 86.7% in aspiration cytology, 83.3% in cytodiagosis of cell block and 95% of histodiagnosis of tissue specimen obtained by Franklin-Silverman needle. Through this study it is found that cytodiagnostic method of aspirates and histodiagnosis of the small tissue specimen by Franklin-Silverman needle are very useful adjunctive methods in enhancing the diagnostic accuracy of the soft tissue and bone lesion prior to open biopsy trial.

Bacteriological index(BI) was calculated by slit-skin smears taken from the earlobe and the dorsal surfaces of the proximal phalanges of the index finger and of the great toe in 110 lepromatous leprosy patients who have been treated regularly by antileprosy chemotherapy. The bacteriaI indices from the three sites were compared, and the results were as follows. 1) Sixteen patients whose BI of the earlobe smear was 4. 0 in average shawed the highest degree of positivity of M. leprae in the smears taken from the finger and the great toe. 2) ln seventy-four patients whose BI of the earlobe smear was l. 0 or higher, eight (10.8%) showed higher BI in smears taken from both the finger and the great toe, fifteen (20. 3%) and twenty-seven(36. 5%) showed approximately the same BI in smears taken from the finger and the great toe, respectively, 3) In thirty-six patients whose BI of the earlobe smear was negative, twelve (33. 3%) showed higher BI in smears taken from both the finger and the great toe. 4) The mean value of BI of the three sites was 3.7 in the earlobe, 3. 2 in the finger and 3. 0 in the great toe. Comparing the BI of the three sites, the finger and the great toe were found to have comparable BI with the earlobe, although the BI of the earlobe was highest. The authors concluded that it was quite reasonable to include the finger and the great toe in slit-skin smears for M. leprae identification, particularly when the BI of the earlobe was negative. A follow-up investigation seems mandatory.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 1999;26(6):1095-1100
Utile recently, osteotomy & reposition surgery of prominent zygoma have been performed by means of a coronal incision or intraoral preauricular incision. But penalties are paid, such as scar, the possibility of facial nerve injury and long operative time. Reflecting on our past experiences of facial bone surgery, we developed an alternative approach. In our method, the protrusion in the cheekbone is corrected by performing an osteotomy and reposition method through intraoral incision only. During the past 3 years we have operated on 23 patients of malar prominences. The amount of the bone to be removed is determined on preoperative interview, physical examination and x-rays. Intraoral incision provide access to the zygomatic body and lateral orbital rim. After L-shaped osteotomy, two paralle vertical and one transverse osteotomies, at medical part of the zygomatic body, the midsegment is removed. Posterior portion of zygomatic arch was approached through medical aspect and was outfractured using curved osteotome. After completion of triple osteotomy, the movable zygomatic complex was reduced medially and fixed with miniplates and screws on the zygomaticomaxillary buttress. The patients were followed for 9.5 months with acceptable result and little complication. The author concludes that this technique is effective and safe method in reduction malarpalsty.

Korean Journal of Nuclear Medicine 2000;34(1):22-29
PURPOSE: We compared the first postoperative diagnostic and post-therapy scans of patients who received therapeutic doses of I-131, to investigate the difference in clinical outcomes between patients with concordant findings of diagnostic and post-therapy scans and patients with discrepant (more lesions in post-therapy scan) findings. MATERIALS AND METHODS: The first postoperative diagnostic and post-therapy radioiodine scans of one hundred forty three patients with well differentiated thyroid carcinoma were reviewed. Diagnostic scans were obtained following ingestion of 185 MBq of I-131 and post-therapy scans were obtained after therapeutic dose of 3.7~9.3 GBq of I-131. Successful ablation was defined as no radioiodine uptake on diagnostic radioiodine scan and normal range of serum thyroglobulin level (<10 ng/ml) during serum TSH elevation. RESULTS: Discrepant scan findings were noted in 25 (17.5%) patients. Twenty-two patients (15.4%) showed more lesions in post-therapy scan and 3 patients (2.1%) showed stunning effect. Nine (64.3%) of 14 patients with distant metastasis revealed metastatic lesion(s) only on post-therapy scan. Stunning effect was considered as sublethal damage in 1 patient and treatment by a diagnostic dose in 2 patients. Ablation was achieved in 52.4% (75/143) of all patients. Ablation rate and mean cumulative radioiodine dose were not different statistically between concordant and discrepant groups. CONCLUSION: There were 17.5% difference between diagnostic and post-therapy scan findings when using 185 MBq of I-131 as a diagnostic dose. However, 64.3% of distant metastases were revealed only on post-therapy scan. Ablation rate and mean cumulative radioiodine dose were not different statistically between concordant and discrepant groups. The stunning effect was considered as not only sublethal damage but also treatment by a small diagnostic dose of radioiodine.

In this study, author tried to clarify the chronological and histological change of the growing spine after posterior cement fixation in dogs. The material used for the study consisted of 24 male mongrel dogs, aged 8 weeks. Lumbar spines, from 3rd to 5th were fixed posteriorly with bone cement (Zimmer Co. U.S.A.). After posterior spinai fixation with bone cement, there dogs at a time were sacrificed every 4 weeks up to 32 weeks, and histologic changes of intervertebral disc, growth plate and the vertebral bodies were observed after hematoxylin & eosin stainning with light microscope. The results obtained were as follows: 1. Thinning of the growth plate and distortion of the cartilage columns developed gradually after posterior cement fixation of the spine, but premature closure of the growth plate did not develop and the growth of the vertebral body continued till 32 weeks after operation. 2. Intervertebral disc thinned posteriorly and widened anteriorly without any changes in subchondral cortices, though there is some bony atrophy in the body which is represented by the thinning and coarseness of bony spicules. 3. At 16 weeks the cartilage layer of the vertebral end plate became thinner, and at 32 weeks there were profound degenerative changes in the cartilages. 4. After fixation of the spine, the nucleus pulposus gradually degraded and was replaced by fibrous tissues, and began to adhere to the vertebral end plate at 24 weeks and completely adhered to it at 32 weeks after fixation. 5. The direction of the horizontally arranged annulus fibrosus began to derange from 24 weeks after fixation, and at 32 weeks all the fibers of the annulus fibrosus were vertically arranged completely. Through this study it is found that posterior spinal fixation with bone cement affects growths of the vertebral growth plate, and end plate slightly, but there were no cessation of cartilaginous growth which might later cause the vertebral deformity. Also it is clarified that posterior fixation of e spine with cement develops noticeable degenerative changes in the intervertebrai disc and thereby develops the lordotic curve of the cemented segment of the spine.

Since Palmer's introduction of the torn medial collateral ligament, many clinical and anatomical studies were performed. But any reconstructive procedure of the medial collateral ligament of the knee known to us, has not solved the problem completely yet. The purpose of present study is to describe a technique of reconstruction, socalled Tatsuzawa's tenodesis surgery of transposed semitendinosus tendon, and is to report the clinical results of 45 cases treated by his procedure between April 1976 and June 1981. In addition, significance of the procerdure was compared with the result of primary closure group of the torn ligament. Tatsuzawa's procedure consists of reinforcement surgery of the repaired or unrepaired torn medial collateral ligament with forwardly transposed semitendinosus. The semitendinosus tendon was brought forward to lie adjacent to deep layer of the medial collateral ligament. The transposed part of the tendon was sutured throughout its length to the medial collateral ligament and to the medial aspect of the tibia and femoral condyle. Because the direction of transposed tendon as similar to the direction of fibers of medial collateral ligament, the procedure was very simple and anatomical one, and had some functional advantages. In this series some old cases are treated only with tendon reinforcement operation without repairing the laxed torn ligament. The results of the surgery were evaluated by the Asais modification of the Feltons evaluation criteria. Results obtained were as follows: 1. In semitendinosus tenodesis with or without primary repair of the torn ligament, satisfactory results were obtained (excellent and good) in 33 cases (73.3%). But in 20 cases of the primary repair group, the satisfactory results were obtained in 11 cases (55%). More satisfactory results were obtained with the semitendinosus tendon reinforcement operation of the torn ligament than only with primary repair. 2. In 29 cases with fresh injury of the medial collateral ligament in which the primary repair together with the tendon reinforcement procedure was performed, satisfactory (excellent and good) results were obtained in 72.4% (21 cases), and in 16 untreated old cases in which only the tendon reinforcement procedure were done, satisfactory results were obtained in 75%. 3. In 5 cases having medial collateral and anterior cruciate ligaments tear, excellent results were obtained in 3. This explains that semitendinosus tendon reinforcement procedure is the key one of the reconstructive operative procedures. It is thought that the procedure is also effective for the anterior cruciate tear to provide the anterior instability.

The distal tibial physeal plate is the second most frequently injured physis and the percentile incidence of its injury is reported to reach 11 percent of all physeal injuries. After physeal injuries, many complications may follow such as angulatory deformity, incongruity of the joint surface, and growth disturbance, which are well recognized. Therefore, for preventing these complications, we have to know mechanism of injury and position of foot in injury. There are several published articles about classification of these injuries. The first traumatological classification of ankle injuries in children is the one proposed by Bishop. Although there were many reports about classification since Bishop, those did not mention the position of foot in injury. Recently a modified classification by Dias and Tachdjian added the postiton of the foot during injury to the direction of the force as Lauge-Hansen did. There were only few reports about epiphyseal and physeal injuries of the ankle in Korea. Also, we could not find the reports which dealt with more than forty cases. The authors have made a clinical analysis on forty cases of childrens ankle fractures, and among them twenty-two could be followed over a year, who were treated at the Department of Orthopaedic Surgery, Kang-Nam St. Marys Hospital, from June 1981 to December 1986. Children were in age of 3 to 16 years. Forty cases were classified according to modified Dias and Tachdjians. 15 out of 40 cases (37.5%) had supination and external rotation injury, which is the most frequent mechanism of injury in this series. However, one case (2.5%) which was suspected to be axial compression type could not be accommodated to this classification. Twenty-seven cases were treated by gentle closed reduction and immobillization in a plaster cast, and thirteen by open reduction and internal fixation. Among the 22 cases who were followed over a year, five cases had complications, such as angulatory deformity, incongruity of the joint surface, and growth disturbance. Three cases out of these five cases had incongruity of the joint surface.

10.Pavlov's Ratio of Cervical Spine of Normal Koreans : Determining Spinal Stenosis on Routine Lateral Roentgenograms
Myung Sang MOON ; Kee Yong HA ; Dae Young JEONG
The Journal of the Korean Orthopaedic Association 1989;24(5):1307-1312
The accepted radiographic method to determine cervical spinal stenosis is the direct measurement of the sagittal diameter of the spinal canal on the routine lateral view of the cervical spine. The reported normal and abnormal values for this measurement are inconsistent because of various methods of obtaining the roentgenograms and different body types which affect the size of the X-ray image. According to Pavlow, the ratio method of determining crevical spinal stenosis, in which the sagittal diameter of the spinal canal is divided by the sagittal diameter of the corresponding vertebral body, is independent of technical factor variables and is a reliable method for determining cervical spinal stenosis. In order to determine the Pavlov's ratio of normal Koreans, and compare it with that of radiculopathic group, we measured the diameter of cervicl canal in 47 normal persons(28 male, 19 female), and 32 patients( 9 male, 23 female) who had transient tingling sensation and radiculopathic symtom from the second to fifth decades. The results were as follows :1) The average Pavlov's ratio from C3 to C7 in normal Korean men are 0.906(0.70–1.13), 0.899 (0.070–1.13),0.948(0.70–1.67) and 0.948(0.67–1.17), respectively, and those of normal Korean women are 0.977(0.83–1.15), 1.021(0.83–1.13), 1.014(0.84–1.33) and 1.055(0.88–1.18), respectively. 2) The average Pavlov's ratio from C3 to C7 in radiculopathic Korean men are 0.88(0.65–1.12), 0.90(0.68–1.12), 0.95(0.79–1.12) and 0.95(0.78–1.06), respectively, and those of radiculopathic Korean women are 0.902(0.70–1.27), 0.905(0.69–1.27), 0.939(0.70–1.33) and 0.931(0.70–1. 18), respectively. 3) There are not statistically differences of the Pavlov's ratio between the control group and the radiculopathic group. 4) We believe that the Pavlov's ratio is an effective method in detection of cervical stenosis and is able to eliminate technical factor such as body position, target and object-to-film distanc.
