Background: Thoracoscopic R3 sympathicotomy can effectively treat palmar hyperhidrosis. Here, we evaluated post-operative outcomes of patients receiving a thoracoscopic R3 sympathicotomy due to palmar hyperhidrosis. Material and Method: From January 2001 to December 2006, 225 patients were treated with a R3 sympathicotomy, and follow up was completed for 200 patients, with an average follow up period of 51.7 ($11{\sim}80$) months. We measured postoperative hand sweating according to four grades; dry (grade 1), proper (grade 2), light sweating (grade 3), heavy sweating (grade 4) and evaluated patient satisfaction using 4 grades: very good (grade 0), good (grade1), regular (grade 2), and deficient (grade 3). Result: There were no differences in clinical parameters between the compensatory sweating group and the non-compensatory sweating group. There was a 83.5% compensatory sweating rate. The degree of compensatory sweating related to the patient's body mass index and was influenced by the season, environmental temperature, and emotional stress. Conclusion: The satisfaction rate was 61.5%, and the degree of satisfaction related to the development of compensatory sweating. Therefore, reducing compensatory sweating would increase patient satisfaction with R3 sympathicotomies.

Purpose: To evaluate the survival rate, local failure rate and patterns of failure, and analyze the prognostic factors affecting local relapse of ductal carcinoma in situ treated with breast conserving surgery and radiotherapy Materials and Methods: From June 1995 to December 2001, 96 patients with ductal carcinoma in situ treated with breast conserving surgery and radiotherapy were retrospectively analyzed. The operations were either local or wide excision in all patients, with an axillary lymph node dissection performed in some patients. Radiation dose to the whole breast was 50.4 Gy, over 5 weeks, with 1.8 Gy daily fractions, with additional doses ($10\~14$ Gy) administered to the primary tumor bed in some patients with close ($\leq$2 mm) or positive resection margin. The median follow-up period was 43 months (range $10\~102$ months). Results: The 5-year local relapse free survival and overall survival rates were 91 and $100\%$ respectively. Local relapse occurred in 6 patients ($6.3\%$). Of the 6 recurrences, one was invasive ductal cell carcinoma. With the exception of one, all patients recurred 2 years after surgery. There was no regional recurrence or distant metastasis. Five patients with local recurrence were salvaged with total mastectomy, and are alive with no evidence of disease. One patient with recurrent invasive ductal cell carcinoma will receive salvage treatment. On analysis of the prognostic factors affecting local relapse, none of the factors among the age, status of resection margin, comedo type and nuclear grade affected local relapse. Operation extent also did not affect local control (p=0.30). In the patients with close resection margin, boost irradiation to the primary tumor bed did not affect local control (p=1.0). Conclusions: The survival rate and local control of the patients with ductal carcinoma in situ treated with breast conserving surgery and radiotherapy were excellent. Close resection margin and boost irradiation to the primary tumor bed did not affect local relapse, but further follow-up with much more patients is needed.

Skeletal class III malocclusion with aterior deep bite is difficult to manage properly, especially in case of mild mandibular prognathism. We have designed lower anterior segmental osteotomy for improving the lower third of the facial contour. Considerable improvement of esthetic facial contour with correction of cross bite in anterior incisors was observed in patients with mandibular prognathism.

Tooth ankylosis is frequently resulted from trauma. If indicated, surgical correction is useful osteotomy is one of the method orthodontic surgery that realigns each tooth to the desirable position by using interdental alveolotomy. This method is being adapted when conventional orthodontic of tooth ankylosis on the anterior maxilla via unitooth osteotomy with literature review.

Lesions of the long head biceps tendon pulley are frequent causes of shoulder dysfunction and pain. These lesions cause instability of the long head of the biceps tendon (LHB), and intra-articular tear of the subscapularis and the supraspinatus tendon might result from them. The arthroscopic repair of these lesions has not gained widespread acceptance as an effective procedure. Predictable results can be obtained by treating these lesions more definitively with tenotomy or tenodesis. The purpose of this article is to review the anatomy and properties of the LHB pulley and to provide treatment strategies for alleviating pulley lesions.

The Incidence of synovial sarcoma Is very low but sarcoma Is a well-defined entity, which occurs primarily around large Joints and usually in association with tendon sheaths, bursae or the capsule. Recently we experienced a case of synovial sarcoma which invaded the right femoral vein of 433 5-year-old man. The tumor was widely excised incl ding the invaded femoral vein, and vein reconstruction was done using saphenous vein graft. The postoperative course was uneventful without intractable edema nor disability.

편측 왜소증의 얼굴을 상하악과 하악 모두 신장할 필요가 있는 경우 하악을 신장하여 상악도 신장시키는 방법을 최근 소개한 바 있으나 본 논문에서는 오히려 상악을 신장시킬 때 하악도 같이 신장시키는 방법을 개발하여 좋은 결과를 얻었다. 두 명의 편측안면 왜소증 환자에서 양악 동시에 골 신장술을 시행하였다. Ortiz Monasterio의 방법과 달리 상악은 구내 르포트씨 제일 골절단술을 시행하였고, 하악은 구내 시상분할 골 절단술을 이용하여 골신장시 저항을 최소한으로 줄이려 하였다. 편방향 구내 골 신장기와 스플린트를 이용하여 양악 골신장술을 시행하였다. 5일의 잠재기 후 매일 1mm의 골신장을 시행하였고 6주에서 8주간의 경화기를 둔 후, 골 신장기와 스플린트를 제거하였다. 골신장 길이는 각각 13mm와 15mm이었고, 특이할 만한 부작용은 관찰되지 않았다. 이에 본 교실에서는 상악신장을 바탕으로 양악을 신장시키는 새로운 술식을 보고하는 바이다.

The purpose of this study was to investigate whether rhBMP-2 (BMP2) could induce synergistic effect with $Pro-Root^{(R)}$ MTA (MTA) in pulpotomized teeth in the rats. Healthy upper first molars from thirty-two, 10 weeks old, Sprague-Dawley rats were used for this investigation. The molars were exposed with round bur, and light pressure was applied with sterilized cotton to control hemorrhage. 1.2 grams of MTA cement was placed in right first molars as a control group. In left first molars, $1\;{\mu}g$ of BMP2 was additionally placed on exposed pulps with MTA. All cavities were back-filled with light-cured glass-ionomer cements. The rats were sacrificed after 2 weeks and 7 weeks, respectively. Then histologic sections were made and assessed by light microscopy. Data were statistically analyzed via student t-test with SPSSWIN 12.0 program (p < 0.05). Inflammation observed in 2 weeks groups were severe compared to the 7 weeks groups. But the differences were not statistically significant. BMP2-addition groups had less inflammation than MTA groups in both periods, though these differences were also not statistically significant. In conclusion, the combination of BMP2 and MTA showed no differences with MTA only for pulpotomy of rat teeth.
