  • Interrupted aortic arch with concomitant intracardiac defects is a rare congenital anomaly that has an unfavorable natural course. We report a successful staged operation of interrupted aortic arch with apical muscular ventricular septal defect associating esophageal atresia with tracheoesophageal fistula in a 3-day-old neonate weighing 2.6 kg. We repaired esophageal atresia through the right thoracotomy and subsequently performed extended end-to-end anastomosis of the aortic arch with pulmonary artery banding through the left thoracotomy at same operation. The apical muscular VSD was repaired 87 day after first operation. The patient required multiple additional interventions before closure of the apical muscular ventricular septal defect, such as pyloromyotomy for idiopathic hypertrophic pyloric stenosis, anterior aortopexy for airway obstruction, and balloon aortoplasty for residual coarctation. She is now doing well.

  • Most patients with acquired maxillary surgical defects have difficulties such as functional impairments of mastication, speech, and deglutition as well as various degrees of facial deformity. The purpose of a prosthetic approach is to restore function and appearance with an obturator as normal as possible. This goal can be achieved when there is thoughful preoperative communication between a prosthodontist and a surgeon regarding a rehabilitation. In this case report, prosthetic rehabilitation was planned before the surgery for the patient diagnosed with squamous cell carcinoma in the right maxillary sinus with careful oral examination. Four months after maxillectomy, a definitive obturator was fabricated following the surgical and interim obturation phase. The objective of this case report is to describe the satisfactory results of the patient with improved rehabilitation of mastication, speech, deglutition, and appearance.

  • A 5-day-old male Korean native calf was referred with the primary complaint of anorexia, absence of feces, depression, and abdominal distention. Although this case was tentatively diagnosed as atresia coli, plain and contrast radiography was performed to confirm site and appearance of obstruction. A plain radiograph revealed gas distension in the large intestine, with absence of fecal material in the descending colon. In a contrast radiograph, the blind part of descending colon that was accumulated with contrast media smoothly protruded to distended colon with gas and the middle part was seen as narrow. These findings were well corresponded with the mucosal blockage junction between distended spiral loop with gas and descending colon that was hypoplasia or atropy in necropsy. In conclusion, contrast radiography was considered very useful method to identify the site and type of obstruction in diagnosis of atresia coli.

  • Gangilosides are ubiquitous membrane components in mammalian cells and are suggested to play essential roles in cellular phenomena such as cell-cell interadion, differentiation, and signal transduction. Rat ovary contained GM3 as major gangiloside. Nn order to study GM3 distribution in the atretic follicles and its possible changes during follicular development, frozen sections were stained with spedfic monocional antibodies against eleven gangilo-series gangliosides including GM3. In the atretic follicles, Glf3 was expressed in a spatlo-temporally different manner during foilicular development, but GM1 and other gangliosides were not immunohistochemicaily detected. in atretic follicle from primary follicle stage, GM3 was expressed in all the theca cells and some granulosa cells adjacent to oocyte. In atretic follicle from secondary follicle stage, GM3 were expressed in all theca cells and granulosa cells. in atretic follicles from developing Graaflan follicle stages, GM3 was similarly expressed as in secondary follicle stage.

  • The role of the posterior palatal seal is important in retention of the maxillary complete denture. After taking the final impression, additional retention can be given to the maxillary denture through a mechanical method of forming a groove on master cast, but this is often overlooked in the clinical process. As a result, the posterior palatal seal is formed in a uniform way by the technician without considering the individual characteristics of the patient. Until now, various types of posterior palatal seal have been introduced by many people. This case report describes the process of manufacturing the maxillary complete denture by determining the position and form of an appropriate posterior palatal seal after considering the patient's anatomical palatal form and tissue displacement during function.

  • This study aims to evaluate the accuracy and completeness of Korean and English closed captions for Netflix's "Squid Game" and to present implications based on the findings. To achieve this, the closed captioning guidelines of the U.S. Federal Communications Commission, DCMP, and the Korea Communications Commission were identified and analyzed. The analysis of the subtitle of the entire "Squid Game" series reveals that, while Korean closed captions accurately present slangs and titles, they present non-existent information in speaker identification. In English closed captions, speaker identification guidelines are well followed, but omissions of slangs and title mistranslations are observed. In terms of completeness, both Korean and English closed captions are found to omit certain audio parts. To address these issues, the study suggests strengthening the QA process, establishing a system to communicate original text problems during translation, and utilizing general English subtitles.

  • Background: Radiofrequency endovenous ablation of incompetent saphenous vein has gaining popularity over the conventional ligation and stripping as a minimally invasive technique. The latest version of radiofrequency endovenous catheter, $VNUS^{\circledR}Colosure$ fast VNUS medical Technologies, San Jose, CA, adopted a segmental ablation system, instead of continous pullback, is designed to reduce treatment time in comparison with the previous model $VNUS^{\circledR}Colosure$ plus VNUS medical Technologies, San Jose, CA. The purpose of this study is to compare the difference between two endovenous radiofrequency ablation systems in terms of treatment efficacy and complication rates. We analyze the initial efficacy and complication rates of $VNUS^{\circledR}Colosure$ fast with $VNUS^{\circledR}Colosure$ plus. Material and Method: Between June 2006 and August 2009, $VNUS^{\circledR}Colosure$ plus was performed to treat varicose vein on 59 limbs in 41. patients and $VNUS^{\circledR}Colosure$ fast was performed on 76 limbs in 67 patients. We retrospectively compared in both group with sex, mean treatment time, mean treatment diameter, conjugated treatment, and complications after the procedure. Result: All patient were symptomatic and diagnosed as varicose vein and underwent level 2 clinical classification with color duplex scan. The mean treatment time for the great saphenous vein was significantly less with $VNUS^{\circledR}Colosure$ fast ($17.0{\pm}6.5min$) than $VNUS^{\circledR}Colosure$ plus ($62.7{\pm}9.8min$). There was no significant difference in 1 yr closure rate between groups (p=0.32). Minor complications such as skin burn, thrombophlebitis, ecchymosis, hematoma, cellulitis, tenderness, and there were not different between the groups. Conclusion: Both $VNUS^{\circledR}Colosure$ fast and $VNUS^{\circledR}Colosure$ plus are effective methods of endovenous saphenous ablation. $VNUS^{\circledR}Colosure$ fast is superior to the previous model with less treatment time preserving compatible efficacy and complications. The efficacy of $VNUS^{\circledR}Colosure$ fast for long term closure rate remains to be established.

  • We assessed the intermediate-term result of tricuspid annuloplasty (TAP) for tricuspid valve regurgitation (TR) associated with congenital heart disease in adults. Risk factors for residual TR were also analysed. Material and Method: From August 1989 to June 2001, seventy three adult patients, 51 females and 22 males, underwent TAP for TR associated with various congenital heart disease. Their age ranged from 46 years to 73 years (mean:43). Associated heart anomalies were atrial septal defect (55), ventricular septal defect (6), partial anomalous pulmonary venous return (4) and others (8). Preoperative and post-operative TR velocities were 3.25 m/sec and 2.56 m/sec respectively, and the types of TAP were De Vega in 43, Kay in 18 and Ring annuloplasty in 12. Postoperative follow-up duration was 2,347 patient-month (mean: 32.6 months), and 134 two-dimensional echocardiographic examinations were done during this period. Residual TR greater than III/IV was considered as TAP failure. Result: TAP failure was observed in 7 patients (9.6%), and one patient among them underwent tricuspid valve replacement. Risk factors for TAP failure were diagnosis other than atrial septal defect (p=0.001), preoperative (p=0.038) and postoperative (p=0.028) high TR velocity. There was no statistical significance in terms of TAP methods. Conclusion: Careful evaluation of valve morphology and aggressive surgical intervention are mandatory for the repair of TR with preoperative or residual RV pressure overload.

  • Aggressive revascularization of the ischemic lower extremities in atherosclerotic occlusive diseases or acute embolic arterial occusion due to cardiac valvular disease by thromboembolectomy or an arterial by- pass operation has been advocated by some authors. To evaluate clinical pattern and operative outcome of the ischemic lower extremity, surgical experience in 101 patients who were admitted to Dong-A Univer- sity Hospital between March 1990 and August 1995 was analyzed. The patients were 92 males and 9 females ranging fro 25 to 87 years of age. The underlying causes of arterial occlusive disease were atherosclerotic obliterances in 54 case, Buerger's disease in 20 cases, thromboembolism in 24 cases, vascular trauma in 3 cases and pseudoaneurysm in 3 cases. - The major arterial occlusive sites of atherosclerotic obliterance were femoral artery in 30 cases, iliac artery in 23 cases, popliteal artery in 10 cases, distal aorta in 6 cases and the major arterial occlusive sites of Buerger's disease were posterior tibial artery in 14 cases, anterior tibial artery in 8 cases, popliteal artery in 5 cases. The operative procedures of arterial occlusive disease were bypass graft operation in 61 cases, thromboembolectomy in 21 cases, sympathectomy in 20 cases. Arterial bypass operations with autogenous or artificial vascular prosthesis were done in 61 cases which Included femoro-popliteal bypass in 21 cases, femoro-femoral bypass in 15 cases, axillo-bifemoral bypass in 7 cases, aorto-bifemoral with inverted Y-gr ft In 3 cases, femoro-profundafemoral bypass in 3 cases, popliteo-tibial bypass in 2 cases, aorto-iliad bypass in 1 case Over all postoperative patency rates were 83.6 oyo at 1 year, 75.5% at 3 years and limb salvage rate was 86.8 oyo . Six patients died in the hospital following vascular surgery for ischemic lower extremities, although the causes of death were not directly related to the vascular reconstructive operative proccedures. The leading causes of death were in the order of multiple organ failure, acute renal failure, and sepsis.
