1.Compression osteosynthesis Of Dsplaced Subcondylar Fractures using Lag Screws.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1999;26(5):890-897
Conservative or surgical methods have been used for the treatment of fracture of mandibular subcondyle, but consensus has not been reached in regard to the proper management of this injury. Several problems related to the surgical procedure have led many surgeons to avoid surgical management of condylar fractures in favor of closed reduction and intermaxillary fixations. However, luxation of the condyle may lead to various long-term complications such as open bite on the contralateral side, dysfunction, deviation in opening and closing movements, as well as bone apposition leading to ankylosis. As a consequence, open reduction is preferable when the condyle is displaced. Various methods-for example, direct wiring technique, simple bone plating, dynamic compression plating-have been advocated for the treatment of fracture of mandibular subcondyle. Of such methods, a functionally-stable osteosynthesis can be achieved by compression osteosynthesis methods. Lag screw osteosynthesis is essentially a form of compression osteosynthesis in which the bone fragments are bound to one another as a result of traction from the screw. An advantage of compression osteosynthesis is that the end of a fractured bone can be maintained in an opposed position under pressure, and then primary bone healing occurs by direct osteoblastic activity within the fracture. As well, it obviates or reduces the need for maxillomandibular fixation, as well as the morbidity associated with conventional treatment methods such as facial nerve injury and bone resorption due to wide dissection. We have treated 9 cases of displaced subcondylar fractures of the mandible with the lag screw fixation system which is marketed by the Martin corporation. Mobilization and guidance of the jaw was begun from 7 or 10 days postoperatively. The radiologic and clinical evaluations showed good repositioning of the fragments and good occlusion postoperatively The disadvantage is that surgical procedures are relatively compound, and an additional procedure - removal of lag screw - is necessary after complete bone union. Lag screw osteosynthesis can be added as a another valid armament for plastic surgeons in the management of mandibular subcondyle fractures.

3.EPICANTHOPLASTY USING MODIFIED UCHIDA'S METHOD .
Journal of the Korean Society of Aesthetic Plastic Surgery 1999;5(2):364-370
In the majority of East Asian eyelids, the presence of a medial epicanthal fold is one of the unique anatomic characteristics. Roundness of medial canthal area and a narrow, short palpebral fissure are aesthetic consequences of this anatomic features. But, the idea of beauty has changed with time by influence of western culture. Many people are favorable to the wide open eye without epicanthal fold, which make improved facial balance. Double-eyelid operation is the most commonly performed procedure of aesthetic surgery field in Korea. However, many cases of successfully done double-eyelid operation results in only partial improvement by leaving medial epicanthal folds. We can get the improved results by utilizing epicanthopasty that lengthens the palpebral fissure, and thus producing the image of a larger, open eye. Consequently the requirements for epicanthoplasty has increased in modern time. The Uchida's split V-W plasty is one of the most frequently used methods. But, it has disadvantages of completely exposed scar, potential for dog-ear formation, and two stage procedure with some cases of double-eyelid operation. We modified the Uchida's method by moving the position of 2 triangular flaps more laterally and conjoining the incision line of double-eyelid operation with that of epicanthoplasty. The purposes of our modification are not complete elimination but relieving the epicanthal fold, hiding the minimal scar behind the new relieved the new relieved fold and preventing the dog-ear on the transitional zone. From January, 1995 to June, 1999, this method was applied to 93 patients who have medial epicanthal folds and performed with double-eyelid operation concomitantly. Age ranged From 12 to 47 years and the mean age was 23 years. Through the mean 15 months of follow up, the mean widening of the palpebral fissure width was 2.5mm and the mean reduction of the intercanthal distance was 5mm. The modified Uchida's method has advantages of simplicity in procedure, effectiveness in results, minimal scarring with hiding behind the new small fold, and one stage procedure with double-eyelid operation. We think it can be applied generally to almost of all double-eyelid operation except epicanthal fold is marked severe.

6.Determinants of Amount of Service Use in Community-Based Long-term Care for Elders.
Journal of Korean Academy of Nursing Administration 2012;18(4):402-413
PURPOSE: This study was done to explore factors related to amount of service use for elders with long-term care needs. METHODS: A descriptive-correlation design was used. The sample included 259 elders and their primary caregivers who had cared for the elders for at least 6 months. Data on long-term care need assessment, service use and interviews with primary caregivers were analyzed. RESULTS: There was no significant relationship between the sociodemographic characteristics and the amount of services use. Amount of service use differed significantly by Long-term care classification. The mean scores for class 1, 2 and 3 were 22.68, 21.47 and 17.87 days respectively. Primary caregiver relationship with the elders and the number of family-friend helpers were also significant. Multivariate regression analysis showed that gender, marital status, activities of daily living, cognitive impairment, and secondary caregiver support explained 17% of the total variance of service use among these elders (F=3.50, p<.001). CONCLUSION: The results of this study indicate that critical factors including secondary caregiver support and individual background, and other functional dependencies except for physical function should be considered in accurately predicting the amount of service use for community dwelling elders with long-term care needs.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

A case of calcifying synovial sarcoma, occuring in the deep muscle fascia of the left thigh is reported. The presence of extensive calcification in synovial sarcoma is a favorable sign for prognosis. The patient was a 31-year-old female. The tumor mass had been present for 3 years, accompanying local tenderness. X-ray revealed a soft tissue tumor with central calcification, which was located between the adductor magnus and brevis of the left thigh. The tumor size was 7 x 5.5 cm. There was no connection with the knee joint or the femur. Grossly, the tumor was a relatively well circumscribed hard tumor with massive calcification. Microscopically, the tumor was composed of predominantly spindle cells with accompanying hyalinization, numerous spherical concretions and ossification. The epithelial component was not clearly noted. Mitotic figures were rarely noted in the densely cellular area. Immunohistochemical staining for EMA, S-100, vimentin, and carcinoembryonic antigen was negative while vimentin and cytokeratin were weakly and focally positive. EM study revealed multiple desmosome-like calcification intercellular junctions with a slit-like lumen and an incomplete basal lamina, which suggest that tumor show these cells were undergoing epithelia] differentiation. Above evidence suggest that this tumor is a synovial sarcoma associated with a large area of calcification, a so called calcifying synovial sarcoma. No recurrence was noted in one and half years of follow up.

This report concerns a rare malignant smooth muscle neoplasm of the skin and the subcutaneous tissue, which was examined immunohistochemically and ultrastructurally. It occured in a 48-year-old female patient who had suffered from painful nodules on the left shoulder. The nodules were removed and diagnosed as a benign fibrohistiocytic tumor. One year after local excision, multiple nodules were detected by physical examination at the previous operation site. Grossly, thirteen well-defined small nodules had spread in the dermis and the subcutaneous tissue, of which nine were located from lower dermis to the subcutaneous tissue and four were in the subcutaneous tissue. Histologically, each nodule consisted mainly of epithelioid tumor cells having eosinophilic or clear plump cytoplasm and round to oval nuclei with small nucleoli, and some peripheral spindle tumor cells. The tumor cells were negative for PAS reaction with and without diastase digestion or alcian blue. Immunohistochemically, tumor cells were positive for smooth muscle actin and vimentin. Ultrastructurally, the tumor cells showed actin filaments and dense bodies in cytoplasm. This case was diagnosed as an epithelioid leiomyosarcoma of the skin and the subcutaneous tissue with local metastasis one year after local excision.
