The incidence of brachial plexus injury is increasing because of the development of motor vehicle but the the results of treatment was reported poor due to its complex anatomical structure and changes of function and sensory during the recovery after trauma. But the results of treatment has been improved by the recently introduced high sensitive diagnostic method that can evaluate accurately the site and extent of the injury and treatment method. Restoration of the elbow flexion is the most important goal of treatment after brachial plexus injury and nerve graft, neurotization and muscle transfer were used for methods of treatment. From December 1992 to May 1994, the author performed 6 cases of latissimus dorsi transfer at the same side for the improvement of elbow flexion in the patients of brachial plexus injury. There were 5 cases of male, one case of female and average age was 22 years old. The causes of injury were traffic accident in 3 cases, gun shot injury, falldown and birth injury in each one case and in all cases, the type of injury were upper arm type. The average follow up period were 1 year 5 months ranging from 12 months to 4 years 5 months. In all cases, active elbow flexion was impossible before operation and average muscle power was grade I. We analysed the active range of motion, muscle power and the functional results. At the last follow up, range of active elbow flexion was average $124^{\circ}$ and flexion contracture was average 11 degrees and the average of muscle power was grade IV. In the functional analysis, there were two cases of excellent, three cases of good and 1 case of fair. There was no complications including wound infection, vascular compromise and donor site problem. The results of latissimus dorsi transfer for improvement elbow flexion in the patients of brachial plexus injury is one of the useful mettled for the restoration of elbow flexion.

Purpose: Cardiotoxicity is a serious late complication of breast cancer treatment. Individual treatment risk of specific drugs has been investigated. However, studies on the evaluation of the composite risk of chemotherapeutic agents are limited. Methods: We retrospectively analyzed the medical records of breast cancer patients who received adjuvant treatment and had available serial echocardiography results. Patients were assigned to subgroups based on chemotherapy containing anthracyclines (A), anthracyclines and taxanes (A+T), and radiotherapy (RT). The development of cardiac disease and serial ejection fraction (EF) were reviewed. EF decline up to 10% from baseline was considered grade 1 cardiotoxicity and EF decline >20% or absolute value <50% was considered grade 2 cardiotoxicity. The most recent medical records and echocardiography results over 1 year of chemotherapy completion were also reviewed. Late cardiotoxicity was defined as a lack of recovery of EF decline or aggravated EF decline from baseline. Results: In total, 123 patients were evaluated. A small reduction in EF was observed after chemotherapy in both chemotherapy groups. There were no significant differences between groups A and A+T in EF decline following chemotherapy. We could not find any differences in composite risk between the chemotherapy groups and the RT group during follow-up. Late cardiotoxicity was seen in 15.45% of patients. During follow-up, three patients were diagnosed with dilated cardiomyopathy. Conclusion: There was no significant composite risk elevation following adjuvant treatment of breast cancer. However, late cardiotoxicity was considerable and further research in this direction is necessary.

Objectives This study aimed to investigate the effect of SJS non-resistance technique-facial palsy (SJSNRT-F) using Korean medicine treatment on facial nerve palsy through three case studies. Methods SJSNRT-F, with other Korean medicine treatments, was performed on three patients who underwent treatment at OO Korean Medicine Hospital from March 2021 to August 2021. Additionally, the House-Brackmann grading system (H-B grade) and Yanagihara's unweighted grading system (Yanagihara's score) were evaluated in these patients. Results There was a significant increase in the Yanagihara scores. Except for one patient who was discharged early, two patients showed improvement in the H-B grade. Conclusions This study suggests that Korean medicine treatment including SJSNRT-F may affect the treatment of facial nerve palsy. However, better clinical studies are needed to confirm the same.

Purpose: Thoracic radiotherapy is a major treatment modality of stage III non-small cell lung cancer. The normal lung tissue is sensitive to radiation and radiation pneumonitis is the most important dose-limiting complication of thoracic radiation therapy. This study was performed to identify the clinical and dosimetric parameters related to the risk of radiation pneumonitis after definitive radiotherapy in stage III non-small cell cancer patients. Materials and Methods: The medical records were reviewed for 49 patients who completed definitive radiation therapy for locally advanced non-small cell lung cancer from August 2000 to February 2010. Radiation therapy was delivered with the daily dose of 1.8 Gy to 2.0 Gy and the total radiation dose ranged from 50.0 Gy to 70.2 Gy (median, 61.2 Gy). Elective nodal irradiation was delivered at a dose of 45.0 Gy to 50.0 Gy. Seven patients (14.3%) were treated with radiation therapy alone and forty two patients (85.7%) were treated with chemotherapy either sequentially or concurrently. Results: Twenty-five cases (51.0%) out of 49 cases experienced radiation pneumonitis. According to the radiation pneumonitis grade, 10 (20.4%) were grade 1, 9 (18.4%) were grade 2, 4 (8.2%) were grade 3, and 2 (4.1%) were grade 4. In the univariate analyses, no clinical factors including age, sex, performance status, smoking history, underlying lung disease, tumor location, total radiation dose and chemotherapy were associated with grade ${\geq}2$ radiation pneumonitis. In the subgroup analysis of the chemotherapy group, concurrent rather than sequential chemotherapy was significantly related to grade ${\geq}2$ radiation pneumonitis comparing sequential chemotherapy. In the univariate analysis with dosimetric factors, mean lung dose (MLD), $V_{20}$, $V_{30}$, $V_{40}$, MLDipsi, $V_{20}$ipsi, $V_{30}$ipsi, and $V_{40}$ipsi were associated with grade ${\geq}2$ radiation pneumonitis. In addition, multivariate analysis showed that MLD and V30 were independent predicting factors for grade ${\geq}2$ radiation pneumonitis. Conclusion: Concurrent chemotherapy, MLD and $V_{30}$ were statistically significant predictors of grade ${\geq}2$ radiation pneumonitis in patients with stage III non-small cell lung cancer undergoing definitive radiotherapy. The cutoff values for MLD and $V_{30}$ were 16 Gy and 18%, respectively.

하악골에서 low grade 골육종은 매우 드물게 보고되고 있으며 조직검사상 conventional osteosarcoma와는 달리 pleomorphism을 보이지 않기 때문에 양성종양으로 underdiagnosis되기 쉽다. 그러나 정확한 환자의 진단은 적절한 치료와 환자의 예후에 영향을 큰 영향을 미친다. 그러므로 조기에 정확한 진단을 위하여는 의심되는 여러부위에서 조직검사를 시행하고 임상소견과 방사선소견 등을 병리의사와 공유하여야 한다. 이에 저자들은 초기에 진단이 어려웠던 하악골에 발생된 low grade 골육종을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

The atrioventricular node reentrant tachycardia[AVNRT] is a common type of supraventricular tachycardias. Recently we experienced two cases of AVNRT. One is AVNRT with severe aortic regurgitation[grade IV] and the other is AVNRT with patent ductus arteriosus. Dissection of perinodal tissue has been successfully carried out in the beating heart under the normothermic cardiopulmonary bypass, and aortic valve replacement and ligation of patent ductus arteriosus were also performed, respectively. Postoperatively, permanent atrioventricular block was not occured and AVNRT was not developed during the follow up. We propose that the surgical dissection of perinodal tissue is a simple and effective treatment for the patient with refractory AVNRT.

Mucoepidermoid carcinoma is one of bronchial adenoma which arising from submucosal gland or mucosal gland of lower respiratory tract. The symptoms of the tumor were produced by bronchial irritation and bronchial obstruction such as coughing, pneumonitis, and atelectasis. The malignancy potency of this tumor was determined by histologic pattern but high grade malignancy was uncommon and so distant metastasis was rare. Three treatment modality such as surgery, radiotherapy, chemotherapy were used for treatment but radiotherapy and chemotherapy were lesser effective than surgery. So Early and radical resection of tumor was recommended. Here we report one case of mucoepidermoid carcinoma which treated with radical resection.

In this study, the influence of pre-treatment(bleaching, mercerization by liquid ammonia and caustic soda) on cotton fabrics were investigated on dyeing Rubia cordifolia extracts. Aluminium Sulfate, Iron(Ⅱ) Sulfate Heptahydrate, Copper(Ⅱ) Sulfate Pentahydrate, Tin(Ⅱ) Sulfate, Manganese(Ⅱ) Chloride Tetrahydrate were used as mordanting agents. K/S value and washing fastnesses of the dyed cotton fabrics pretreated under different conditions were investigated. The K/S values were increased in the order of bleaching, liquid ammonia and mercerization pre-treatment. It was found that the pre-treatment conditions did not significantly affect the color change. The colorfastness to washing of most of all dyed fabrics were over grade 4 regardless of pre-treatment condition.
