Aim: To examine lymph nodes obtained after lipolysis and liposuction of subcutaneous fat of the inguinal region of female vulvar cancer patients to explore the feasibility of clinical application. Methods: The field of operation was on the basis of the range of the conventional resection of inguinal lymph nodes. We injected lipolysis liquid fanwise, started liposuction after 15-20 minutes; then the subcutaneous fatty tissue was sucked out clearly by suction tube. We selected the first puncture holes located on 2-3 cm part below anterior superior spine, the others respectively being located 3cm and 6cm below the first for puncturing into the skin, imbedding a trocar to intorduce $CO_2$ gas and the specular body, and excise the lymph nodes by ultrasonic scalpel. The surgical field chamber was set with negative pressure drainage and was pressured with a soft saline bag after surgery. Results: A lacuna emerged from subcutaneous of the inguinal region after lipolysis and liposuction, with a wide fascia easily exposed at the bottom where lymph nodes could be readily excised. The number of lymph nodes of ten patients excised within the inguinal region on each side was 4-18. The excised average number of lymph nodes was 11 when we had mature technology. Conclusion: Most of adipose tissue was removed after lipolysis and liposuction of subcutaneous tissue of inguinal region, so that the included lymph nodes were exposed and easy to excise by endoscope. This surgery avoided the large incision of regular surgery of inguinal region, the results indicating that this approach is feasible and safe for used as an alternative technology.

Burning mouth syndrome(BMS) refers to a chronic orofacial pain disorder usually unaccompanied by mucosal lesions or other clinical signs. Tongue(anterior and lateral border) is found to be the most common site for the burning sensations in the oral cavity, and various oral sites may be affected including hard palate and lips. The etiology of this disorder remains poorly understood, but the various factors might be related with the pathogenesis of the BMS. These factors have been devided into local, systemic and psychological. Recently, there have been increasing reports that the pain of BMS may be neuropathic in origin. The complex and multifactorial etiology of BMS necessitates multidisciplinary approach for the management of these patients. Recently, several studies have reported that oral parafunctional habits could be related the pathogenesis of BMS, and tried to control the symptom of BMS with various methods. We reported the cases who had the symptom of burning mouth syndrome with removable anti-nociceptive appliance in the lower dentition.

The purpose of this study was to evaluate the result after 2-phase surgical-orthodontic treatment without preoperative orthodontic treatment for the skeletal Cl III malocclusion patient and to obtain an adequate protocol on the bases of this result. This retrospective study of ten patients who underwent 2-phase treatment were done to evaluate 1) the surgical stability and relapse pattern 2) the facial esthetics 3) the TMJ problem 4) the total time of the treatment. Results were followed : 1) The horizontal relapse of the mandible was 26.8% and didn't show significant differences compared to the conventional 3-phase treatment. But, it was considered that this amount of relapse was the sum of true relapse and autoratation of mandible due to decreased vertical dimension during orthodontic treatment. 2) It was estimated that there's no difference on the ratio of anterior facial height between the subjects and the normal patients. On the horizontal analysis, the mandible of the subjects was located more anteriorly than that of the normal patients. This result showed that there was a need for the accurate preoperative esthetic evaluation and the additional methods for reducing the relapse due to the occlusal interference. 3) Wide variation was noted on the TMJ symptoms of the subjects, however, it was estimated that there's no significant differencees of symptoms compared to that of the conventional 3-phase treatment on literatures. 4) The average of the overall period of treatment was 20.8 months and we obtained reduction of the treatment time compaired to 3-phase treatment on many literatures. Most of the results of this study were similar to the findings of the 3-phase treatment(preoperative orthodontic-orthognathic surgery-postoperative orthodontic), but total time of the treatment was shorter in patients with 2-phase treatment than in those with the conventional 3-phase treatment. With 2-phase treatment, we experienced many advantages compared to the conventional method considering that it was favarable conditions for the teeth, it had the flexibility for the treatment, and it could be the adequate treatment approach for the stomatognathic system. Although this retrospective pilot study had some limitations, due to small samples, the authors would hope that it could serve as a guide for the future researches, and the clinical applications.

The Dentigerous cyst is reported to be one of the most common lesions of the jaw. It is derived from reduced enamel epithelium that surrounds the crown of an unerupted tooth. Dentigerous cysts usually remains asymptomatic and presents as well-circumscribed radiolucencies surrounding the crown of a tooth. Most dentigerous cysts are treated by surgical enucleation or marsupialization of the cyst to allow eruption of the permanent tooth. The nasopalatine duct cysts derived from the islands of epithelium remaining after closure of the embryonic nasopalatine duct. The cyst presents as a well-circumscribed oval or heart-shaped radiolucency located in the midline of the anterior maxilla between the roots of the central incisors. Treatment is by surgical enucleation, employing a palatal approach. This report present two cases. One case was diagnosed with dentigerous cyst and treated by enucleation. 12 Months later, affected second premolar was erupted normally. The other case was diagnosed with nasopalation duct cyst. Histological examination of the enucleated cyst confirmed a nasopalatine duct cyst. There was no recurrence during follow up period.

The conservative treatment for impingement and rotator cuff tear includes rest, nonsteroidal anti-inflammatory drugs (NSAIDs), local steroid injection and physiotherapy depending on the purpose to relieve the pain and inflammation, in addition, stretching exercise to recover flexibility and strengthening exercise to recover the function could be used. When these conservative treatments are divided into multiple steps, the first one contains pain relief, modification of daily activity and stretching exercise. Second step includes strengthening exercise of the anterior/posterior cuff and peri-scapular muscles and eventually. The third step includes training program to return to job, housework and hobby activities and maintain. Thus, the key of these step wise approach for the treatment of impingement and rotator cuff tear is exercise program. Understanding of various exercise program and apply to the patients properly is most important for the conservative treatment of impingement and cuff tear.

The biomimetic approach on the cuticular spinning nozzles of the major ampullate silk glands in the golden-web spider Nephila calvata has been attempted using various visualizing techniques of light and electron microscopes to improve the design of spinning nozzle for producing synthetic nanofibers spun from electrospinning apparatus. The major ampullate spigot which has the most effective nozzle system to produce nanofibers for dragline silk with high strength and elasticity is connected via the bullet type spigot on anterior spinneret with flexible terminal segment. The excretory duct which transports the liquid silk feedstock from ampulla to spigot is divided into 3 limbs by loops back on itself to form an S-shape morphology that is bundled in connective tissue. Final diameter of the nanofibers at nozzle was dramatically reduced by gradual narrowing of duct cuticle less than 10 times comparing to its original size of funnel region. Moreover, the funnel has a characteristic cuticular organization with porous microstructure which seems to be related to water removal from feedstock of silk precursors. High magnification electron micrographs also reveal the presence of the spiral grooves on the surface of the cuticular intima near the valve which presumed to reduce friction during rapid flow of liquid silk.

Purpose: To report the mid-term results of the inferior capsular shift procedure for the multidirectional instability, and to analyze whether the bilateral laxity, the generalized ligamentous laxity and the voluntary instability can influence upon the final outcome. Material and Method: We reviewed 95 patients with 96 shoulders treated by the inferior capsular shift procedure for multidirectional instability through an anterior approach. In total, 49 shoulders(51%) showed generalized ligamentous laxity, 56 shoulders(58%) bilateral laxity, and 65 shoulders(68%) voluntary subluxation. Mean follow-up was 27 months(11-60 months). Result: The final Rowe score was 75 points in patients who had had at least one of the bilateral laxity, generalized ligamentous laxity, or the voluntary subluxation and 84 points without any of these in each element. Seventy-five percent of the bilateral laxity and 87% of the unilateral instability continued to function well without any pain and instability postoperatively. Those with a voluntary(74%), those with an involuntary instability(83%), those with a generalized ligamentous laxity(73%) and without laxity(84%) could do well a daily living activity without instability Eighty-six percent who had had the voluntary instability was eliminated completely the voluntability. Eighty-four percent of the patients stated that they were subjectively satisfied with the status of their shoulder. Nine shoulders(9.4%) had recurrence of symptomatic and disabling instability and theses patients had had at least voluntary instability preoperatively. Seven patients(7.3%) suffered from the stiff shoulder after the inferior capsular shift procedure. Conclusion: The inferior capsular shift procedure in multidirectional instability provided satisfactory results both in objective and subjective terms. Nonetheless, a patient who has a bilateral laxity, a generalized ligamentous laxity or a voluntary instability could be expected less favorable results compared to those with neither of these. A careful selection of the inferior capsular shift procedure for the multidirectional instability is needed before surgery. But our results suggests that a voluntary instability is not always poor candidate for the inferior capsular shift procedure.

Purpose: To report the results of surgical treatment of comminuted fractures of distal humerus and to identify factors that affect the results. Materials and Methods: Thirty-two patients who were treated with open reduction and internal fixation for comminuted fracture of distal humerus were enrolled. According to the AO classification, A2.3 was 1 case, A3.2, 2 cases, A3.3, 8 cases, B1.3, 1 case, B2.3, 1 case, C2.2, 5 cases, C2.3, 4 cases, C3.2, 3 cases and C3.3, 7 cases. As fixation technique, 17 cases were fixed by double plates, 4 cases by only K-wires, 4 cases by only screws, 3 cases by K-wires and screws and 4 cases by one plate and screws. The mean age at the time of the operation was 49 years(range, $19{\sim}77$ years). The mean follow-up period was 16 months(range, $8{\sim}51$ months). Results: At the last follow-up, the mean maximum flexion was $116.4^{\circ}\;(range,\;85{\sim}140^{\circ})$ and the mean loss of terminal extension was $11.8^{\circ}\;(range,\;0{\sim}40^{\circ})$. The average Mayo elbow performance score was $91.4^{\circ}\;(range,\;55{\sim}100^{\circ})$. Overall 29 cases(91%) showed good to excellent results. The mean range of motion of extraarticular and intraarticular fracture group was $105.5^{\circ}\;(range,\;65{\sim}140^{\circ})$ and $104^{\circ}\;(range,\;55{\sim}140^{\circ})$, respectively. The average elbow score of both groups was$93^{\circ}\;(range,\;70{\sim}100^{\circ})$ and $90.7^{\circ}\;(range,\;55{\sim}100^{\circ})$. Over 90% showed more than good results. 30 cases(94%) showed complete bony union but two cases, nonunion. One case of the nonunion cases underwent replating with bone graft as revision surgery and total elbow arthroplasty was performed in the other case. At the last follow-up, 27 patients(84.4%) showed subjective satisfaction. Conclusion: Open reduction and internal fixation with appropriate surgical technique for comminuted fractures of distal humerus showed good results, which were not affected by age at the time of operation, fixation methods and anterior transposition of the ulnar nerve. Transolecranon approach may be considered as good choice for intraarticular comminuted fractures of distal humerus.

Objectives : Our study aimed to investigate the sustained effects of sham (SHAM) and verum acupuncture (ACUP) into the post-stimulus resting state. Methods : In contrast to previous studies, in order to define the changes in resting state induced by acupuncture, changes were evaluated with a multi-method approach by using regional homogeneity (ReHo) and amplitude of low frequency fluctuation (ALFF). Twelve healthy participants received SHAM and ACUP stimulation right GB34 (Yanglingquan) and the neural changes between post- and pre-stimulation were detected. Results : The following results were found; in both ReHo and ALFF, the significant foci of; left and right middle frontal gyrus, left medial frontal gyrus, left superior frontal gyrus, and right posterior cingulate cortex, areas that are known as a default mode network, showed increased connectivity. In addition, in ReHo, but not in ALFF, brain activation changes in the insula, anterior cingulate cortex, and the thalamus, which are associated with acupuncture pain modulation, were found. Conclusions : In this study, results obtained by using ReHo and ALFF, showed that acupuncture can modulate the post-stimulus resting state and that ReHo, but not ALFF, can also detect the neural changes that were induced by the acupuncture stimulations. Although more future studies with ReHo and ALFF will be needed before any firm conclusions can be drawn, our study shows that particularly ReHo could be an interesting method for future clinical neuroimaging studies on acupuncture.

Recently, video-assisted thoracoscopic surgery for mediastinal lesions has been considered a new effective therapeutic method. From March, 1992 to April, 1997, 33 cases of video assisted thoracoscopic surgery for mediastinal lesions were performed. Gender distribution was 16 males and 17 females. Average age was 42 years old(ranged from 14 to 69). The locations of lesions were anterior mediastinum in 14 cases, middle mediastinum in 5 cases, posterior mediastinum in 11 cases, and superior mediastinum in 3 cases. These included 9 neurilemmomas, 5 benign cystic teratoma, 4 pericardial cysts, 2 ganglioneuroma, 2 thymus, 2 thymic cyst, 1 thymoma, 2 esophageal leiomyomas, 1 dermoid cyst, 1 lipoma, 1 malignant lymphoma, 1 bronchogenic cyst, 1 pericardial effusion, and 1 Boerhaave's disease with empyema. Working window was needed in 6 cases. We converted to open thoracotomy in 6 cases. Reasons of convertion to open thoracotomy were large sized mass(1), severe adhesion(3), and difficult location to approach(2). The average operation time was 116min($\pm$56 min). The average chest tube drainage time was 4.7days. The average hospital stay was 8.7 days. Operative complications were atelectasis(2), empyema with mediastinitis(1), recurrent laryngeal nerve palsy(1), and plenic nerve palsy(1). In conclusion, VATS for mediastinal lesions were performed with shorter operation time and hospital stay, and lesser complications and pain than those of conventional thoracotomy.
