A case of bladder prolapse through a patent urachus is reported in a female infant born with a large, red, tubular mass inferior to the umbilical cord. A cystic mass communicating with fetal bladder was detected by prenatal ultrasound performed at $20^{+2}$ weeks of gestation. A fetal MRI was also performed to confirm the diagnosis and to exclude associated fetal anomalies. At $40^{+4}$ weeks, the cystic mass was no longer present and a new small solid mass was noted at the fetal abdominal wall. After birth, a protruded mucosal mass inferior to the umbilical cord was noted, and catheterization confirmed communication between the protruded mass and the urinary bladder. On the second day of life, reduction of the bladder and partial resection of the urachus was performed. A voiding cystourethrogram showed good bladder capacity and no vesicoureteral reflux. The patient voided well and was discharged after 10 days. Here, we present a case of urinary bladder prolapse through a patent urachus, diagnosed by fetal sonography and this is the first case reported that was treated by simple excision without complication.

Background : Interpretative reporting is an important aspect of laboratory medicine. The large menu of laboratory tests available today makes it increasingly difficult for the non-specialist to order and interpret all laboratory tests. The aim of this study was to determine the usefulness of an expert system to interpret laboratory tests and help physicians order the appropriate tests. Materials and Methods : In order to interpret laboratory tests, a rules-based expert system was developed. In this module, if-then rules were used to interpret the given test result patterns (e.g. urinalysis, anemia, hepatitis B virus, hypercholesterolemia, glucose, syphilis, and tumor markers) and select matching text elements. The system was used to evaluate 535 subjects who visited a health-check program. Results : The overall abnormal rate was 50.5% in the expert system; 34% for cholesterol, 9.9% for urinalysis, 8.0% for anemia, 7.7% for thyroid function tests, 4.5% for tumor marker study, 4.7% for hepatitis virus antigen, 4.3% for serum glucose, and 1.1% for syphilis. Conclusion : These results indicate that the application of the expert system for the interpretation of laboratory tests may provide a useful method for the interpretation of reports. However more rules are needed for the application to in-patients.

Purpose: To evaluate the usefulness of ultrasonography in diagnosis of the medial meniscus tear as a screening tool before performing magnetic resonance imaging. Materials and Methods: From April 2009 to September 2010, magnetic resonance imaging (MRI) was taken in 147 knees out of 341 knees examined with ultrasonography (US) under the suspicion of medial meniscus tear. The sonographic findings were 16 without abnormality, 12 inhomogeneity, 4 cluster, 60 cleavage and 55 more than 5mm medial extrusion of medial meniscus. In Statistical analysis, sensitivity and specificity, positive predictive value and negative predictive values were calculated. Results: The MRI showed abnormality in 104 knees. Sensitivity and specificity of ultrasonography for MRI was 94.2% and 23.3%, respectively. Positive predictive value was 74.8%, negative predictive value was 62.5%. The positive predictive value of ultrasonography were 58.3% in heterogeneity, 100% in showing cluster, 75% in visible cleft and 80% in medial extrusion. Conclusion: The US is a useful tool in prediction of medial meniscus tear before confirming it in high-cost MRI.

Background: Aortic diseases tend to involve the entire aorta. Hence, there is the constant possibility of the need for a secondary operation at the remnant aorta. This study analyzed our cases of secondary aortic surgery in order to determine its characteristics and problems. Material and Method: Between April 2003 and June 2007, 12 patients (6 male and 6 female) underwent thoracoabdominal aortic replacement as a secondary aortic operation. Their clinical courses were analyzed. Four of the patients underwent lower thoracobadominal aortic replacement under the normothermic femorofemoral bypass, and the others underwent an entire thoracobdominal aortic replacement under deep hypothermic circulatory arrest. Result: There was no death or paraplegia. As local complications, there were 3 cases of wound infection and 2 cases of an immediate reoperation caused by bleeding and one case of delayed wound. revision for a contaminated perigraft hematoma. As a systemic complication, there was one case of renal insufficiency, which required hemodialysis and one case of respiratory insufficiency that needed prolonged ventilator care. The mean admission period was $30{\pm}21$ days. All the patients were followed up for $626{\pm}542$ days without reoperation or other problems. Conclusion: Using properly selected patients and a careful approach, thoracoabdominal aortic replacement can be performed safely as a secondary aortic surgery.

The purpose of this study is to survey the status of oral care of adult patients with disabilities and satisfaction degree of outpatient general anesthesia for dental treatment. 30 adult patients who underwent general anesthesia for dental treatment at clinic for the disabled in Seoul National University Dental Hospital enrolled for telephone survey. Many patients (83.3%) had mental problems to do social communication. And someone of family members (mainly mother) had cared for the patient but there was only one patient who got regular oral care. The satisfaction level of outpatient general anesthesia and nursing care for dental treatment was very high(100%).

Thymic carcinoid or neuroendocrine tumor of thymus is a very rare disease and has poor prognosis due to frequent recurrence and distant metastasis. A 43-year-old man was refered to our hospital because of Rt. chest pain and tightness. Chest X-ray revealed $7{\times}8$cm sized mass on Rt. anterior mediastinum. Surgical excision was performed and light microscopic, immunohistochemical and electron microscopic findings were confirmed as atypical thymic carcinoid tumor with thymic cyst. The patient has been followed up without recurrence or distant metastasis postoperatively for 3 months to now. We report a case of atypical thymic carcinoid with thymic cysts.

Total anomalous pulmonary venous return is a rare but serious cardiac malformation, accounting for only about 1.5~3% of congenital heart disease. Surgical results have been dramatically improved in the last two decades, largely owing to improved techniques of cardiopulmonary bypass and perloperative management. Seven patients ranging in age from 15 days to 11 years with total anomalous pulmonary venous return underwent repair between 1984 and 1995. The types of anomalous return were supracardiac in 5, and cardiac in 2. There were 5 boys and 2 girls. There were two hospital death, occurred in 15-day-old, and 40-day-old infants with supracardiac type. Follow-up periods have ranged from 3 months to 11 years, and all survivors have remained asymptomatic with normal growth and development.

The DiGeorge syndrome is a rare congenital abnormality consisting of aplasia or hypoplasia of the thymus and parathyroid glands resulting from malformation of the third and fourth pharyngeal pouches. This syndrome usually includes congenital cardiac anomalies and abnormal facial features. We experienced a case of congenital cardiac anomaly associated with DiGeorge syndrome. The patient was 1 month old boy weighing 3.5 kg. The congenital cardiac anomalies included ventricular septal defect, atrial septal defect, coactation of aorta, and patent ductus arteriosus. We performed one-stage operation with two separate incisions for these cardiac anomalies. Postoperative course was uneventful and the patient at 6 months of follow up is doing well.

We treated 654 patients with simultaneous bilateral sympathectomy for essential hyperhidrosis from March 1989 to September 1997(354 males and 300 females). The exposure afforded by thoracoscopy is actually superior to that seen at the time of either thoracotomy or axillary thoracotomy. The use of single-lumen intubation with alternating partially collapsed lung by CO2 inflation resulted in shorter anesthesia, shorter operative time, and shorter hospitalization. 2-mm extended thoracoscopic T2-sympathectomy is not only a time-saving method but also a very simple and effective one in the treatment of hyperhidrosis by experienced surgeons. The modification on our technique of thoracoscopic sympathectomy as described allowed us to significantly improve our previous results. A majority of the patients were relieved, and over 95% were satisfied initially.

Extramedullary hematopoiesis is a common compensatory mechanism of chronic anemia, but an asymptomatic posterior mediastinal mass is rarely diagnosed as an extramedullary hematopoiesis after surgical resection. The differential from neurogenic tumors is important, but fine needle aspiration biopsy is not recommended because of the difficulty of approach and risk of bleeding. Although diagnosis and treatment can involve resection via thoracotomy, video-assisted thoracic surgery may also be a useful strategy. We performed video-assisted thoracic surgery on a 59-year-old man for posterior mediastinal extramedullary hematopoiesis, with no evidence of recurrence or related hematologic diseases.
