Chylothorax is a rare but serious and well-recognized complication of thoracic and cardiac procedures. A postoperative chylothorax developed in a 3-month-old male patient after ligation of patent ductus arteriosus and repair of coarctation of aorta. He was treated successfully with conservative management using a combination of parenteral octreotide and medium-chain triglyceride (MCT) -enriched fomula with pleural drainage. We report a case of successful conservative treatment using octreotide for postoperative chylothorax.

Severe cases of mandibular prognathism can be treated with orthodontic therapy or surgical correction, but there are situations where only prosthetic improvement is possible. An understanding of class III patients is needed, including a vertical chewing pattern and the absence of anterior guidance. Additionally, it is relatively easy to increase occlusal vertical dimension to correct the anterior crossbite, but this approach can sometimes lead to unfavorable results, necessitating careful diagnosis and treatment planning. In this case report, oral rehabilitation was conducted in a patient with mandibular prognathism and asymmetry, utilizing implants and fixed dental prosthesis. Through a step-by-step treatment approach, the existing occlusal vertical dimension was maintained, and the final fixed dental prosthesis restoration was completed. Accordingly, it shows functional and aesthetically appropriate results, and reports on the patient's diagnosis and treatment process.

Avulsion of the hamstring tendon from the ischial tuberosity is common in many sports, especially with younger athletes. The injury results from a sudden forceful flexion of the hip joint when the knee is extended and the hamstring muscles powerfully contracted. Early diagnosis and surgical repair with reattachment of avulsed muscles to the ischial tuberosity restore function and correct deformity. But, a delay in the diagnosis and treatment leads to a poor result functionally and clinically. Complication, such as heterotopic ossification and failure of the fixation, etc., were reported following a surgical procedure for this injury. However, sciatic nerve injury has not been reported in the literature. We report our experience of a sciatic nerve palsy after surgery that was performed three months after that the initial injury.

Ultrasonographic examination for the rotator cuff disease is dynamic noninvasive study and the results is comparable to MRI on the behalf of recent development. It also can be used as a tool for guided injection and follow up study after rotator cuff repair. The development of equipment, learning curve and knowledge for the disease are the three most important factors for the critical role of the ultrasonography in the diagnosis and treatment of the rotator cuff disease.

Purpose: Recently, the use of radiosurgery as a local therapy in patients with early stage non-small cell lung cancer has become favored over surgical resection. To evaluate the efficacy of radiosurgery, we analyzed the results of stereotactic body radiosurgery in patients with primary or recurrent non-small cell lung cancer. Materials and Methods: We reviewed medical records retrospectively of total 24 patients (28 lesions) with non-small cell lung cancer (NSCLC) who received stereotactic body radiosurgery (SBRT) at Inha University Hospital. Among the 24 patients, 19 had primary NSCLC and five exhibited recurrent disease, with three at previously treated areas. Four patients with primary NSCLC received SBRT after conventional radiation therapy as a boost treatment. The initial stages were IA in 7, IB in 3, IIA in 2, IIB in 2, IIIA in 3, IIIB in 1, and IV in 6. The T stages at SBRT were T1 lesion in 13, T2 lesion in 12, and T3 lesion in 3. 6MV X-ray treatment was used for SBRT, and the prescribed dose was 15~60 Gy (median: 50 Gy) for PTV1 in 3~5 fractions. Median follow up time was 469 days. Results: The median GTV was 22.9 mL (range, 0.7 to 108.7 mL) and median PTV1 was 65.4 mL (range, 5.3 to 184.8 mL). The response rate at 3 months was complete response (CR) in 14 lesions, partial response (PR) in 11 lesions, and stable disease (SD) in 3 lesions, whereas the response rate at the time of the last follow up was CR in 13 lesions, PR in 9 lesions, SD in 2 lesions, and progressive disease (PD) in 4 lesions. Of the 10 patients in stage 1, one patient died due to pneumonia, and local failure was identified in one patient. Of the 10 patients in stages III-IV, three patients died, local and loco-regional failure was identified in one patient, and regional failure in 2 patients. Total local control rate was 85.8% (4/28). Local recurrence was recorded in three out of the eight lesions that received below biologically equivalent dose 100 $Gy_{10}$. Among 20 lesions that received above 100 $Gy_{10}$, only one lesion failed locally. There was a higher recurrence rate in patients with centrally located tumors and T2 or above staged tumors. Conclusion: SBRT using a CyberKnife was proven to be an effective treatment modality for early stage patients with NSCLC based on high local control rate without severe complications. SBRT above total 100 $Gy_{10}$ for peripheral T1 stage patients with NSCLC is recommended.

Purpose: To report the results of curative treatment for patients with tonsil cancer by retrospective analysis. Materials and Methods: From Jan. 1995 till Dec. 2000, 27 patients with squamous cell carcinoma of the tonsil received curative treatment at Samsung Medical Center. Therapeutic decision was made through multidisciplinary conference, and curative radiation therapy was favored when, (1) the patient's condition was not fit for general anesthesia and surgery, (2) the patient refused surgery, (3) complete resection was presumed impossible, or (4) too severe disability was expected after surgery. Surgery was the main local modality in 17 patients (S$\pm$RT group), and radiation therapy in 10 (RT$\pm$CT group). The median follow-up period was 41 months. Results: AJCC stages were I/II in four, III in two, and IV in 21 patients. The 5-year disease-free survival rate was 73.3$\%$ in all patients, 70.6$\%$ in the S$\pm$RT group, and 77.8$\%$ in the RT$\pm$CT group. Treatment failure occurred in seven patients, all with stage III/IV, and all the failures occurred within 24 months of the start of treatment. Five patients among the S$\pm$CT group developed treatment failures; 2 local, 2 regional, and 1 distant (crude rate=29.4$\%$). Two patients among the RT$\pm$CT group developed failures; 1 synchronous local and regional, and 1 distant (crude rate=20.0$\%$). The 5-year overall survival rate was 77.0$\%$ in all patients, 80.9$\%$ in the S$\pm$RT group, and 70.0$\%$ in the RT$\pm$CT group. Conclusion: We could achieve favorable results that were comparable to previously reported data with respect to both the rates of local control and of survival by applying S$\pm$RT and RT$\pm$CT. RT$\pm$CT is judged to be an alternative option that can avoid the functional disability after surgical resection.

Skeletodental asymmetries are common and asymmetric orthodontic treatments are very difficult to correct successfully. The cause of asymmetries can be the skeletal asymmetry, dental, or functional, or combinations of these causes. Skeletodental asymmetries can be the result of congenital factors, such as hemifacial microsomia and environmental factors, such as trauma. Optimal treatment outcome of the severe facial asymmetry requires the orthognathic surgery. Mild asymmetry problem can be treated by only orthodontic treatment. The orthodontic treatment of asymmetry is usually difficult. Facial asymmetry orthodontic treatment are primarily based on proper diagnosis and careful treatment planning. Side effects of asymmetric elastic to treat midline discrepancies are canted occlusal plane, tipped incisors and unesthetic results. In the management of dental arch asymmetries, the clinician should select the appropriate force system and the appliance design necessary to address the asymmetry while minimizing undesirable side effects. This report presents treatment strategies for the treatment of skeletodental asymmetry. In this case report, the clinical case with midline discrepancies treated by optimal mechanics is described. Through diagnosis and strategic treatment mechanics can obtain proper midline correction with minimal side effects.

Purpose: To evaluate the end results between the surgical treatment with neo-adjuvant chemotherapy in Korea and non-invasive high intensity focused ultrasound (HIFU) technique in China for osteogenic sarcomas. Materials and Methods: The surgical treatment with neoadjuvant chemotherapy for total 67 cases (4 IIA, 58 IIB, and 5 III) in Korea since 1993 and the HIFU therapy for total 71 cases (57 II and 14 III) in China since 1997 was performed. In Korea, neo-adjuvant chemotherapy in 66 cases out of total 67 patients, but the adjuvant chemotherapy in only one case was done. On the contrary, in China, full chemotherapy for more than 9 times for 37 patients with stage II out of total 71 cases, but for less than 8 times of partial chemotherapy for 23 patients (stage II) and 14 patients (stage III) was done. The surgical treatment in total 67 Korean patients was done with wide resection and reconstruction for 56 patients, but wide resection without reconstruction for 5 patients and amputation for 6 patients. In china, total 71 patients was treated with average 1.5 times (1~4 times) of HIFU, and if there are some evidences of residual tumor after HIFU with following MRI, the second HIFU therapy was given 2~4 weeks later. After then, the bony defect was in no touch, keep bracing for long time expecting regeneration. All of them were followed for average 46 Mo (12~150 Mo) in Korea, but followed for average 22 Mo (9 years~8 months) in China. Results: The 5 year survival rate (stage II), was average 92.7% (IIA 100%, IIB 85.5%) in Korea series, and average 78.7% (full chemotherapy 91.8%, part chemotherapy 56.6%) in China series. The 3 year survival rate (stage III) was 20% in Korea and 7.1% in China. So, the final overall survival rate was 65.2% in Korea and 51.8% in China. The overall functional outcome score by ISOLS was 24.3 (81%) in Korea and 19.8 (73%) in China. There are 25.4% (17/67 cases) of complications in Korea and 31% (27 complications in 22 patients out of total 71 cases) in China after each treatment. Conclusions: The end results of Korea series which was treated with neoadjuvant chemo- and surgical methods are better than that of non-invasive thermal ablation in china. But we also believe the HIFU, as one of, was also effective to decrease the local recurrence and symptomatic releaf for stage II or even in III of osteogenic sarcomas.

In term of the factors affecting psychosocial adjustment of breast cancer patients, their quality of life after surgical operation, radiation, and chemotherapy were systematically meta-analyzed. As a result, their qualities of life of the patients that had radiation therapy was the lowest right after the therapy, and gradually increased after the end of the therapy. However, after six months, their quality of life failed to reach the same level before the therapy. They had depression and side effects the most right after the therapy, and somewhat reduced them after the end of the therapy. In case of surgical operation, the more they were educated, the more they had psychosocial adjustment, and the more they had a medical examination and took out an insurance policy, the more they had psychosocial adjustment. In case of chemotherapy, their cognitive function is influenced so that they have impairments in memory, learning, and thinking stages. Since subjective cognitive impairment has a relationship with depression, it is necessary to monitor depression of chemotherapy patients. Given the results of this systematic meta-analysis, when three types of therapies (surgical operation, radiation therapy, and chemotherapy) are applied to patients with breast cancer, it is necessary to recognize their psychosocial adjustment, depression, anxiety, and quality of life in the nursing and radiation therapy fields and thereby to introduce an intervention program for a holistic approach.

Background : Recently, medical treatment of multi-drug resistant pulmonary tuberculosis has been unsuccessful. Through analyzing the cases with surgical treatment, we hope to provide some help in treating multi-drug resistant pulmonary tuberculosis in the future. Material and Method : A retrospective review was performed with 138cases of surgical treatment of multi-drug resistant tuberculosis during 10years from January 1994 to December 2003 at National Masan Hospital. Results : The ratio of men to women, 5.1:1 indicates that there were more incidences in men. The number of the resistant drugs was 5.3 with a mean age of 42.6 years. Cavitary lesions on the plain chest X-rays were seen in 94cases (68.1%). 128cases had positive sputum culture preoperatively. Types of operations were 24 pnemonectomies, 83 lobectomies, 10 bilobectomies, 19 lobectomies with segmentectomies or wedge resections, 1 wedge resection, and 1 carvenoplasty. There was no death after operation. There were 6cases of air leakage over a week, 6cases of postoperative bleeding, 8cases of bronchopleural fistula and empyema, 16cases of dead space, 1case of atelectasis, 1case of wound infection, 1case of cyst as postoperative complication. Postoperative complication showed higher long-term negative conversion rate of 92.8%. Conclusion : There has been many discussions about operative indications, postoperative drug regimens, length of postoperative chemotherapy. In our study, we showed higher long-term success rate of postoperative chemotherapy with pulmonary resection on multi-drug resistant pulmonary tuberculosis.
