In the instance wherein concentric reduction cannot be achieved by closed method, open reduction is indicated. Prolonged and forceful attempts to reduce the refractory hips are not without risk to the circulation of the femoral head and open reduction is certainly a less traumatic way to obtain reduction in these hips. The authors performed clinical analysis in 30 patients with congenital dislocation of hip who were treated by open reduction between 1978 and 1987, The results are as follows :1. The results of treatment in 30 patients were acceptable in 22(73.3%), uncertain in 4(13. 3%), and unacceptable in 4 patients(13.3%). 2. Comparing the results depending on the presence of prior treatment or not, acceptable results were obtained in 86.4%(19 out of 22) of patients without prior treatment and in only 37.5%(3 out of 8) of patients with prior theatment by such as Pavlik harness and closed reduction. 3. The surgical approaches for open reduction were medial and anterior routes. The approach was selected depending on the age of patients and the severity of dislocation. The medial approach was used in patients under the age of 18 months. In mild degree of dislocation, the age limit of medial approach was extended to 24 months of age. The anterior approach was used in patients over 19 months of age.

PURPOSE: This study was performed to evaluate the success rate, failure causes, complications, safety and effectiveness of extracorporeal shock wave lithotripsy(SWL) with domestic SDS-5000 lithotriptor for the treatment of urinary calculi. MATERIALS AND METHODS: SWL monotherapy using the Domestic SDS-5000 lithotripter was performed in 195 urinary stones from 173 patients between 9 years and 74 years old from March 1998 to February 1999. Distribution of stones, location and size of stones, session, success rate, causes of failure and complications of SWL were reviewed. RESULTS: Of 195 cases, 88(45.1%) had renal, and 107(54.9%) ureteral stones. Of these cases 44.6% had stones smaller than 0.9cm, 33.3% from 1 to 1.9cm, 15.9% from 2 to 2.9cm, and 4% larger than 3cm. The overall success rate of complete SWL was 91.3% with 90.1% in 5-9mm, 96.9% in 10-19mm, 90.3% in 20-29mm and 62.5% over 30mm stone size. There were no significant complications. The cases of transient gross hematuria were developed in 11.3%, renal colic in 8.7%, steinstrasse in 2.0% and fever in 1.0%. These complications were controlled with conservative treatment or repeated session of shock wave lithotripsy, Double - J stent insertion. CONCLUSIONS: SWL with Domestic SDS-5000 lithotriptor is considered to be a safe and efficient outpatient procedure for the initial treatment of urinary stone.

PURPOSE: The purpose of this study was to evaluate the high-resolution CT features of Swyer-James syndrome with special attention to the airway lesions and to determine the clinical utility of high-resolution CT compared with that of chest radiography. MATERIALS AND METHODS: In seven patients with Swyer-James syndrome, we retrospectively reviewed chest radiographs obtained during inspiration and expiration and high-resolution CT scans obtained in inspiration. The high-resolution CT appearance was evaluated and compared with that of chest radiography. RESULTS: On both chest radiographs and high-resolution CT, the affected lung volume was relatively diminished in four patients and normal in three patients. In all seven patients, chest readiographs showed hyperlucency of the lung which was unilateral in four and bilateral in three patients. Unilateral small hilum was seen in six patients and bronchiectasis was demonstrated in one patient on chest radiographs. The hyperlucent lung volume was not diminished on expiratory radiographs in all seven patients. In all patients, high-resolution CT demonstrated low attenuation regions of the lung either bilaterally(n=5) or unilaterally(n=2). Pulmonary vessels were markedly decreased in size and number in the lung parenchyma with low attenuation. Six patients had bronchiectasis on high-resolution CT, which were cylindrical or varicose in five and cystic in one. Bronchiolectasis was observed in three patients on high-resolution CT. CONCLUSION: The high-resolution CT findings are characteristic of Swyer-James syndrome. High-resolution CT is more sensitive than chest radiography in detecting regions of low attenuation and bronchiectasis and may be useful for the diagnosis of Swyer-James syndrome. Our results suggest that bronchiectasis is a frequently associated airway lesion of Swyer-James syndrome and bronchiolectasis may be associated in some cases.

Authors carried out an investigation of the helminthic parasites of the wild birds in Korea. Most wild birds were collected from Kyoung Sang Do, Kyoung Kee Do and Seoul area from September 1970 to March 1973. A total of 70 wild birds, 19 species were examined, which comprised as follows; 10 Anas platyrhynchus, 10 Anas fulicata, 4 Anas poeciolorhyncha zonorhyncha, 8 Anser albifrone albifrone, 5 Anser cygonopsis cygnoid, 10 Aythya fuligula, 6 Gallicrex cinerea, 2 Porgana fusca, 2 Phisianum calichius korponri, 4 Sterptopilla orientalis, Podiceps cristatus, Larus crasirotatus, Malantta fusca, Garis artcus, Buetes buteo, Egretta alba, Starmus philpiens, Bombycilla granulus. Trematode parasites found from six species of the wild birds. Echinostomatidae has been found from intestine of the Anas platyrhynchus platyrhynchus, Anas poeciolorhyncha zonorhyncha, Anas fulcata. Notocatylus attenuatis found from intestine of the Podiceps cristatus, Anas fulcata. Catylurus japonicus was found from rectum of the Anas platyrhynchus platyrhynchus, Anas poeciolorhyncha zonorhyncha.

The requirements of orthodontic wire should include chemical stability, non-discoloration and non-corrosion in oral environment. Ability to be soldered, ease of fabrication and elasticity should be also considered. The purpose of this study was to compare and analyze the physical properties of Tru-chrome. The results were as follows: 1. Tru-chrome wire and E.S.S. wire were SUS 304 which was 18 Cr-8Ni austenite stainless steel. There was not significant difference in each composition between two wires. 2. There were not significant differences in ultimate tensile strength, yield strength, elongation and modulus of elasticity between Tru-chrome and E.S.S. wires. 3. There was not significant difference between flexure modulus of elasticity of Tru-chrome and E.S.S. wires. 4. Micro-hardness value of E.S.S. wire was more than that of Tru-chrome wire and they were softened significantly by solution heat reatment. 5. Micro-structure of Tru-chrome and E.S.S, wires showed fibrous interlocking grains, and an austenite structure after solution heat treatment. 6. There was significant difference between corrosion rate of Tru-chrome and E.S.S wires.

Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.
