Although osteltis fibrosa cystica was the clinical manifestation originally recognized as a feature of the primary hyperparathyroidism, its frequency in diagnosed cases currently has decreased. Affected patients are now being detected in earlier stages of the disease. We have experienced a case of primary hyperparathyroldism with the typical bony changes and the pathologic, subtrochanteric fracture of left femur. We have treated the fracture with Zickel nalling and parathyroidectomy was performed. Four months after the removal of parathyoid adenoma the fractured femur healed well.

More than 100 surgical methods were described as the treatment of recurrent patella dislocation. These can be divided into two categories, the proximal, dynamic reconstruction and the distal, static reconstruction. We treated a case of recurrent patella dislocation with a new method, using gracilis. The tendon of gracilis was dissected and cut at the point about 7cm proximal to the insertion. A 'H' shaped slot was made subperiosteally in the anterior surface of patella. The both ends of cut gracilis tendon were imbedded into the 'H' shaped slot of patella and sutured. So the gracilis tendon could act as a static and dynamic stabilizer. The result was excellent at 1 year follow up.

Experiences of 26 cases of electrical bone stimulation on normal adult rabbits was documented in this paper. The cathodic electrode was introduced longitudinally into the medullary cavity of the proximal tibia and the anodic electrode was introduced transversely in the distal femur of the same side. The contralateral tibia was used as the control, of which the Teflon coated Kirschner wire was introduced longitudinally into the medullary cavity. 10uA of direct current was passed continuously through the fixed wires between the proximal tibia and distal femur. At the second, fourth and sixth week, random bone scan with 99m-Tc was performed and the animals were sacrificed. The specimen X-rays of the tibia and femur were taken and the specimens were prepared for the microscopic study. The followings are obtained from this experimental study. 1. The rate of new bone formation is 69.2% in the stimulated group and 7.7% in the control group. There were also fibrosis and cartilage formation as well as the new bone formation. The fibrosis and cartrilage formation are observed only in the electrically stimulated side and their occurances are 69.2% and 11.1% respectively. So The new bone formation and fibrosis are definitely increased in the bones of the cathodic electrical stimulation than those of the control side. 2. The intramembraneous ossification is the predominent feature of this electrically stimulated new bone formation. 3. Bone and soft tissue necrosis was the main microscopic feature in the anode side. 4. Since new bone, fibrous tissue and sometimes new cartilage were observed in this study, it seems that the cathodic electrical stimulation is not specific for the new bone formation, but induce crude tissues such as bone, cartilage, fibrous tissue or vessels. Furthermore, it can be postulated that the 10uA electrical stimulation is only one of the best electrical environment for the formation of the crude tissues, especially for bone and fibrous tissue.

It has been known that the obesity is one of the predisposing factors of the primary degenerative arthritis of knee. And nowadays, it seems that the number of obese person increases gradually in Korea. The authors studied 50 cases of the degenerative arthritis of knee clinically and statistically, compared with 50 cases of the control group, in the Department of Orthopedic Surgery, Seoul National University Hoispital from Jan. to Aug. 1981. The results were as follows: l. Among the degenerative arthritis of knee, the ratio of male: female was 1:9, and the age group with the highest frequency was the 5th. decade (48%). 2. Thirty-two cases (64%) was obese in the degenerative arthritis group, and 7 cases (14%) was obese in the control group. 3. The incidence of obesity in the degenerative arthritis group was 13.5 times higher than that in the control group, and it was highly significant statistically.

The cubitus varus is one of the most common complications of supracondylar fracture of humerus. The authors treated surgically 45 cases of cubitus varus in the Seoul National University Hospital, from 1977 to 1981, and the results were as follows: 1. The mild ulnar n. palsy signs were found in 11 cases(24.5%). 2. The supracondylar, closed wedge osteotomy was done through lateral approach and fixed by cross pinning with 2 K-wires. 3. The postoperative immobilization must be more complete, and the average duration of immobilization was 7 weeks. The osteotomy site united in the all cases, and no limitation of range of motion developed. 4. The incidence of postop. ulnar nerve palsy was the same in the osteotomy only group as in the osteotomy and ulnar n. transposition group. The osteotomy and ulnar n transpositin group recovered naturally, but 2 cases of the osteotomy only group did not recover so ulnar n. transposition was performed later. 5. There was no recurrence of deformity after the average follow-up of 2.2 years, so it was recommended that the correction of deformity should be done in the early childhood.

BACKGROUND AND OBJECTIVE: The outcome of asthma treatment has traditionally been assessed by measuring the conventional clinical parameters such as symptoms, expiratory flow rates and needs for medications. But none of them tells us whether the patients are actually able to function properly in their lives. Only assessment of the quality of life (QOL) can reflect the parts of patients lives affected by the disease. However, there is no measure to assess the quality of life of patients with any chronic diseases in Korea yet. We developed the QOL Questionnaire for Korean Asthmatics and evaluated its measurement properties. METHOD: The questionnaire was composed of 18 items in four domains : i.e. activity limitation (6 items), symptoms (5 items), emotional function (3 items) and environmental stimuli (4 items). At our out-patient clinic, 32 adults with moderate to severe persistent bronchial asthma were enrolled. The study design consisted of 4 week unblinded single cohort with visits at 0 and 4 weeks, and the patients were asked to answer the questionnaire by self administration method at the two separate visits. Forced expiratory volume for 1 second (FEV1) and peak expiratory flow rate (PEFR) were recorded at each visit. According to the patients and physicians global assessment, the patients were divided into two groups, i.e. stable and changed (improved). The responsiveness, reproducibility and validity of the questionnaire were evaluated. RESULTS: The total QOL scores at the second visit in the changed group were significantly higher than those at the first visit. The score differences between the two visits in the changed group were higher than in the stable group. In the stable group, the responses to the questionnaire were reproducible. The QOL scores showed good longitudinal correlation with the expiratory flow rates, whereas FEV1 did not correlate with the QOL in cross-sectional analysis. CONCLUSION: The questionnaire proved to be reproducible, responsive and valid in the subjects. It could be recommended for the outcome evaluation of Korean asthmatics.

Miliary osteoma cutis of the face is a form of primary osteoma cutis. We report a case of miliary osteoma cutis on the jaw of a 55-year-old female. She presented with several 2~3 mm sized, skin-colored firm papules over both lower jaws for 5 years. Skin biopsy was performed and the specimen showed numerous osteocytes and osteoblasts in the bony tissue which was located in the deep dermis.

The combination of an intradermal nevus with epidermal cyst or other adnexal tumors has often been described since 1952. Most of these reports have involved the coexistence of common epidermal cysts and melanocytic nevi. Herein, we report a 21-year-old Korean male, who initially presented to our department with a rapidly enlarging preexisting nevus on his back. The mass was surgically excised and histopathologically showed intradermal nevus combined with epidermal cyst.
