Diver's bone lesion was described for the first time by Grutzmacher in 1941. Ten cases of osteonecrosis of the femoral head in divers were analysed on the basis of clinical and pathologic feature. The pathologic feature of the osteonecrosis in divers was not reported in Korea previously. The cases were observed from March, 1985 to June, 1988. The authors treated the cases with total hip replacement and obtained good results. The results were as follows:1. The average ate age at the time of operation was 41.5 years. 2. The average follow-up was 20.4 months. 3. The specimens were confirmed as osteonecrosis mieroscopically. 4. By Meyer's modification of Marcus and Enneking classification the average stage was 3.7. 5. Divers bone lesion was increased with the length of diving experiences:diving depth, diving time, age and with bends. 6. The pathologic feature of osteonecrosis in divers differ from that of idiopathic avascular or aseptic osteonecrosis and could be differentiated easily. 7. After total hip replacement, according to Harris hip rading score system, all results were good.

We report a case of acantholytic dyskeratotic epidermal nevus in a 28-year-old female. The patient showed unilateral, asymptomatic, grouped, 2 mm sized, brownish, follicular ant non-follicular, keratotic papules disposed along Blaschko´s lines on the right side of th back, flank and abdomen. She had had this condition for 4 years. The biopsy specimen obtaine, from the abdomen showed hyperkeratosis, parakeratosis, acanthosis, acantholytic suprabasal clefts, corps ronds, and grains. Although cryotherapy with liquid nitrogen was per formed on half of the lesions, the whole skin lesions healed with focal hypertrophic scars 4 weeks later. There was no recurrence after a 12 months follow-up period. To our knowledge this is the first reported case of acantholytic dyskeratotic epidermal nevus in Korean dermatologi, literature.

Fracture of distal one third of tibia is prone to develop angular deformity during weight bearing and delayed union by inadequate immobilization. Most surgeons have performed internal fixation with plate and screws or interlocking Kuentscher nail to provide stability to the fractured tibia. When open reduction and internal fixation is carried out, the periosteum and muscular attachments must be stripped off. And in interlocking Kuentschernailing extraoperative time needed to insert distal screw, and the medullary reaming destroys nutrient circulation by which fracture healing is hindered. However, flexible Ender nailing is a simple procedure which does not necessitate reaming, and also does not disrupt or strip off soft tissues at the fracture site. Authors carried out Ender nailing in 16 patients having distal tibial fractures who were treated at the Orthopaedic Department, Kang-Nam St. Mary's Hospital from February, 1985 to December, 1988. The results are as follows: 1. The radiological union was obtained at 13.3 weeks after operation, and primary healing was taken place. 2. Fractures could be securely fixed by intramedullary Ender nailing. 3. Mild angulation developed in 3 cases, but it did not affect the results. Through the results Ender nailing is proven to be an effective, reliable, and safe method in treatment of fracture of the distal one third of tibia with minimum residua and complication, and brings the natural fracture healing.

PURPOSE: To clarify the chracteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. MATERIALS AND METHODS: We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. RESULTS: The tumors included 33 lipomas, 11 hemangiomas. 11 lymphangiomas, 7 neurilemmomas, 4 epidermold cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The SOhographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxoma), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and chacteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymphangioma. Neurilemmoma showed Iobulated, oval to round, relatively hypoechoic mass with or without internal cystic portion. CONCLUSION: Sonographic evaluation of benign soft tissue tumros is useful in demonstrating the location, size, extent, and internal characteristics of the mass. A relatively confident diagnosis can be made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging.

Rupture of an innominate artery caused by blunt chest trauma is extremely rare because this artery is short and relatively well protected by the bony cage. This report describes a 37-year-old male who sustained a blunt chest injury that resulted in an innominate artery rupture, detected by chest CT and thoracic aortography. The patient underwent an urgent operation through median sternotomy. A 3 by 3 cm sized pseudoaneurysm of proximal innominate artery was found with a complete intimal tear. After the origin of the innominate artery was closed, the injured segment of artery was excised and an aorto-innominate artery bypass with a 10 mm Gore-tex graft was performed without use of a shunt. The patient was discharged 20 days later without neurologic complications and had equal blood pressure in both arms.

BACKGROUND: Elevated plasma homocysteine concentrations are an independent risk factor for vascular disease. The metabolism of homocysteine is closely related to vitamin B12 and folic acid. The purpose of this study is to evaluate the correlation between homocysteine and vitamin B12 as well as folic acid in patients with coronary artery disease. METHODS: Sixteen patients, in whom coronary angiography revealed more than 50% of stenosis at least in one coronary vessel, were enrolled as the patient group, and sixteen hypertensive subjects were selected as the control group. Blood was collected in the peripheral vein to measure the concentrations of homocysteine, vitamin B12, and folate. We evaluated the correlation between homocysteine, vitamin B12 and/or folate in both groups. RESULTS: Total plasma homocysteine concentrations were higher in the coronary artery disease group than in the control group. There were no significant differences in the folate and vitamin B12 levels between the coronary artery disease group and the control group. In the control group, the concentrations of homocysteine showed negative correlation with both vitamin B12 and folate concentrations, but similar trends were not observed in the coronary artery disease group.

The term “non-ossifying fibroma of bone” was introduced by Jaffe and Lichenstein in 1942 to describe a distinctive benign lesion occuring near the ends of the long bones in young people, and the lesion was subsequently described by Hatcher as a developmental defect rather than a true tumor. This lesion was presented as a clear-cut entity on the basis of pathological, clinical and roentgenographic manifestations. The diagnosis of non-ossifying fibroma was made by the histopathological findings of the curetted tissues. The authors have seen and studied 5 cases of non-ossifying fibroma from February 1976 to September 1981. The average duration of follow up was 2.2 years, with a range from 0.8 to 5 years, and the results of treatment were as follows: l. Of the five cases, two were associated with pathologic fractures. 2. The sites of the lesions in all cases were the long bones in the lower extremity. 3 In all cases, the complaints were of only a few days or weeks duration before admission to the hospital, and no cases were discovered incidentally by roentgenographic examination. 4. Good results were obtained by treatment with curettage and bone graft.
