Voice therapy after post-thyroidectomy dysphonia is designed to improve glottal closure without supraglottic hyperfunction by development of abdominal support for breathing and intrinsic muscle strengthening exercises. Regarding voice therapy of unilateral vocal fold paresis/paralysis, several techniques such as head positioning, digital manipulation, pushing and pulling method are used for trial or temporary therapy. And the holistic voice therapy such as LSVT, Accent method, VFE are useful for hypofunctional voice disorders. These may be effective interventions as a temporary improvement until normal voice recovers or may provide the essentials for long-term rehabilitation.

A waste container, one of the key components of a multi-barrier system in a potential high level radioactive waste (HLW) repository in Korea ensures the mechanical stability against the lithostatic pressure of a deep geologic medium and the swelling pressure of the bentonite buffer. Also, it delays potential release of radionuclides for a certain period of time, before it is corroded by intruding impurities. Even though the material of a waste container is carefully chosen and its manufacturing processes are under quality assurance processes, there is a possibility of initial defects in a waste container during manufacturing. Also, during the deposition of a waste container in a repository, there is a chance of an incident affecting the integrity of a waste container. In this study, the appropriate Features, Events, and Processes(FEP's) to describe these incidents and the associated scenario on radionuclide release from a container to the biosphere are developed. Then the total system performance assessment on the Initial waste Container Failure (ICF) scenario was carried out by the MASCOT-K, one of the probabilistic safety assessment tools KAERI has developed. Results show that for the data set used in this paper, the annual individual dose for the ICF scenario meets the Korean regulation on the post closure radiological safety of a repository.
Anastomotic leaks and fistulas are significant complications of gastric surgery that potentially lead to increased postoperative morbidity and mortality. Surgical intervention is reserved for cases with severe symptoms or hemodynamic instability; however, surgery carries a higher risk of complications. With advancements in endoscopic treatment options, endoscopic approaches have emerged as the primary choice for managing these complications. Endoscopic clipping is a traditional method comprising 2 main categories: through-the-scope clips and over-the-scope clips. Through-the-scope clips are user friendly and adaptable to various clinical scenarios, whereas over-the-scope clips can close larger defects. Another promising approach is endoscopic stent insertion, which has shown a high success rate for leak closure, although vigilant monitoring is required to monitor stent migration. Infection control is essential in post-surgical leakage cases, and endoscopic internal drainage provides a relatively safe and noninvasive means to manage fluids, contributing to infection control and wound healing promotion. Endoscopic suturing offers full-thickness wound closure, but requires additional training and endoscopic versatility. As a promising tool, endoscopic vacuum therapy potentially surpasses stent therapy by draining inflammatory materials and closing defects. Furthermore, the use of tissue sealants, such as fibrin glue and cyanoacrylate, has been reported to be effective in selected situations. The choice of endoscopic device should be tailored to individual cases and specific patient conditions, with careful consideration of the nature of the defect. Further extensive studies involving larger patient populations are required to provide more robust evidence on the efficacy of endoscopic approach in managing post-gastric anastomotic leaks.
Purpose: The purpose of this study was to examine the effects of bed angles and bed rest time combined with hemostatic methods on discomfort and hemorrhagic complications in patients after transfemoral cerebral angiography. Methods: Data were collected from 93 inpatients following transfemoral cerebral angiography, from April 20 to September 23, 2016. Patients were grouped according to bed angle ($0^{\circ}$ vs. $30^{\circ}$) and bed rest time combined with hemostatic methods (4-hour bed rest after manual compression vs. 2-hour bed rest after applying vascular closure device). Results: There was a significant group differences on discomfort (F=46.44, p<.001). The post-hoc analysis showed the lowest score of discomfort in those with bed angle $30^{\circ}$ and 2-hour bed rest. There was no difference in hemorrhagic complications among 4 groups. Conclusion: The postangiograpy discomfort can be effectively reduced with the least hemorrhagic complications by bed angle $30^{\circ}$ elevation and 2-hour bed rest after applying vascular closure device for those underwent transfemoral cerebral angiography.
There are various problems while applying classification or clustering algorithm in that document classification which requires post processing or classification after getting as a web search result due to my keyword. Among those, two problems are severe. The first problem is the need to categorize the document with the help of the expert. And, the second problem is the long processing time the document classification takes. Therefore we propose a new method of web document clustering which can dramatically decrease the number of times to calculate a document similarity using the Transitive Closure Tree(TCT) and which is able to speed up the processing without loosing the precision. We also compare the effectivity of the proposed method with those existing algorithms and present the experimental results.
Pulmonary atresia with intact ventricular septum, and with VSD were uncommon congenital anomalies with high mortality in the neonatal period. Those survivals depend on an adequate interatrial communication or interventricular communication and pulmonary flow via large aortopulmonary collateral including PDA. Recently we experienced surgical correction of 2 cases pulmonary atresia with intact ventricular septum and with VSD. On case 1, 10-years old male patient was confirmed as pulmonary valvular membranous atresia with intact ventricular septum combined with large functioning PFO and mild tricuspid incompetence. So we performed total correction under the E.C.C, that was PDA ligation, RVOT reconstruction with monocusp valved outflow patch [16mm], repair of tricuspid insufficiency and closure of PFO. Post-operative hemodynamic result was good and there was no event during hospital course. On case 2, 16-years old female patient was diagnosed as pulmonary atresia with VSD and PDA. MPA was absent, remained fibrous cord like remnant and type of VSD was subaortic defect [3cm by 3cm in the size]. PDA was located at the usual site. Under the E.C.C. VSD patch closure through the right ventriculotomy, anastomosis between the right ventricular outflow tract and the pulmonary bifurcated site with the extra-cardiac Hancock valved conduit [22cm] and PDA ligation were performed.
Background Human bite wounds in emergency department need evaluation in regard of reconstruction. These are due to occlusive bite injuries over face. Most commonly, human bites over face involve ear and nose, and may lead to avulsion injury. Defects over nose can be reconstructed immediately after debridement or delayed till the wound heals and scar becomes supple. Thorough wash and lavage with broadspectrum antibiotic cover has utmost importance in preventing cartilage infection. Methods We report 20 cases of human bite injuries over nose who presented to us in emergency department between 2018 and 2020. At the time of presentation the wound was assessed for closure. If not possible, patient was planned for delayed reconstruction after 3 months. In case delayed reconstruction was planned, the skin and nasal mucosa were approximated at first presentation. The patients underwent paramedian forehead flap after recreation of defect with conchal cartilage graft. Second stage of flap detachment and insetting was done after 3 weeks. After three weeks of second stage, third stage of flap thinning was done. Patients were followed for 3-6 months and subjective satisfaction was noted. Results Nineteen patients underwent delayed staged reconstruction with paramedian forehead flap and one underwent primary wound closure. The flap survival was 100%. The patient satisfaction was excellent in most cases. Conclusion We recommend delayed reconstruction for human bite nasal injuries. For reconstruction, paramedian forehead flap with conchal cartilage graft, if required, provides excellent reconstructive option with good contour and color match and minimal donor site scar.
Background: This study was aimed at analyzing the preoperative conditions post-operative results indication and methods of surgical closure of patent ducturs arterio년 in prematures low birth weight infants and neonates. Patients and Methods: We retro-spectively studied two groups of patients (prematures group and neonates group) who underwent surgical closure of the patent ductus arteriosus between March 1995 and June 1998. Results: The premature group consisted of 9 patients(3 males and 6 females) Their mean gestational period was 30.7 weeks(ranging from 26 weeks to 33 weeks) mean age 27.8 days(11 days to 55 days) and mean body weight 1.56 kg. Prominent preoperative symptoms were dependency on mechanical ventilation generalized edema and hepatomegaly. We performed PDA ligation via thoracotomy in all premature patients. The neonate group consisted of 16 patients and their mean body weight was 3.75 kg. Major symptoms of this group was tachypnea and intercostal retraction resistant to medical treatment. We performed video-assisted PDA clipping to them all. There were no postoperative complications or operation-related mortality in both groups. Comparing the ratio of size of PDA(mm)/body weight(kg) the ratio of premature group (ligation through thoracotomy) was higher than that of neonate group ( video-assisted clipping) that is 3,89:1.21(p=0.03) Conclusion : We conclude that the surgical closure of PDA can be a safe method of treatment for prematures low birth weight infants and neonates with compromised general conditions. Choice of surgical technique depends on the surgeon's preference but there was a tend-ency to choose the ligation method through thoracotomy for patients with small body weight and large PDA.
Background Aggressive treatment of sternoclavicular joint (SCJ) infection involves systemic antibiotics, surgical drainage and resection if indicated. The purpose of this paper is to describe a classification of post resectional SCJ defects and highlight our reconstructive algorithm. Defects were classified into A, where closure was possible often with the aid of topical negative pressure dressing; B, where parts of the manubrium, calvicular head, and first rib were excised; and C, where both clavicular, first ribs and most of the manubrium were resected. Methods Twelve patients (age range, 42 to 72 years) over the last 8 years underwent reconstruction after SCJ infection. There was 1 case of a type A defect, 10 type B defects, and 1 type C defect. Reconstruction was performed using the pectoralis major flap in 6 cases (50%), the latissimus dorsi flap in 4 cases (33%), secondary closure in 1 case and; the latissimus and the rectus flap in 1 case. Results All wounds healed uneventfully with no flap failure. Nine patients had good shoulder motion. Three patients with extensive clavicular resection had restricted shoulder abduction and were unable to abduct their arm past $90^{\circ}$. Internal and external rotation were not affected. Conclusions We highlight our reconstructive algorithm which is summarised as follows: for an isolated type B SCJ defect we recommend the ipsilateral pectoralis major muscle for closure. For a type C bilateral defect, we suggest the latissimum dorsi flap. In cases of extensive infection where the thoracoacromial and internal mammary vessels are thrombosed, the pectoralis major and rectus abdominus cannot be used; and the latissimus dorsi flap is chosen.
Background: The curative treatment of choice for empyema is decortication of the pleura. The risks of this treatment however are increased for the patient with reduced pulmonary function, complicated calcification or septic shock. In the past, open window thoracostomy was a final stage treatment for chronic empyema. Relatively safe treatment of empyema could be achieved in difficult cases with a closure of the open window after open drainage and use of a myocutaneous flap (one stage or staged). Material and Method: A retrospective study of the cause, progression and final outcome of empyema patients who received open window thoracostomy was performed. 21 patients were followed from 1995 to 2004 in the department of Thoracic and Cardiovascular Surgery in the College of Medicine, Pusan National University. Result: The average age of the patients was $57.5{\pm}15.5$ years (range $25{\sim}78$ years), of whom 16 (76.2%) were men and five (23.8%) were women. Pulmonary function test results showed an average FEV1 of $1.58{\pm}0.49 L$. The type of empyema was tuberculous empyema in 13 cases (61.9%), aspergillosis in three cases (14.3%), parapneumonic empyema in three cases (14.3%) and post-resectional empyema in two cases (10%). Bronchopulmonary fistula was seen in 14 cases. Eight cases were complicated by severe calcification of the pleura. For the four cases of bronchopulmonary fistula, the patients' serratus anterior muscle was covered in their first operation. The average number of ribs resected was $4{\pm}1$. Closure of the open window thoracostomy was performed in 12 cases. The average time to closure after open drainage was $10.22{\pm}3.11$ months and the average defect of the empyemal cavity before the final operation was $330{\pm}110 cc$. Among the 12 cases, there were two cases of spontaneous closure. In two cases closure was only achieved by using the reserved skin fold during the first surgery. Of the remaining eight cases, in seven we used the myocutaneous flap (four cases of lattisimus dorsi muscle and three cases of pectoralis major muscle), and in one case we used soft tissue. As regards complications of the closure, tissue necrosis occurred in one case, which led to failed closure, and there was one case of abdominal hernia in the rectus abdominis muscle flap. One patient died within 30 days of the surgery and one patient died of metastatic cancer. Conclusion: A staged operation with a final closure using open window thoracostomy, which consists of open drainage, transposition of the muscle and a myocutaneous flap, can be a safe and effective option for the chronic empyema patient who is difficult to cure with traditional surgical methods.
