A 7-year-old castrated male Schnauzer was presented with melena and inappetence. Laboratory examination revealed mild anemia. Abdominal ultrasonography showed abnormal enlargement of intestinal segment and a oval mass with soft tissue density. After surgical resection of the enlarged intestine including the mass, histopathologic examination showed that the mass was tentatively diagnosed as synchronous occurrence of gland cell- and mesenchymal cell-origin tumors. Subsequently, immunohistochemistry showed positivity to cytokeratin AE1/AE3 in the gland cells and positivity to ${\alpha}-smooth$ muscle-specific actin, but negative expression of c-Kit, suggesting the co-existence of adenocarcinoma and leiomyosarcoma. Follow-up examination after 3-year of the surgery confirmed that the dog remained healthy and did not show recurrence of the tumors.

A hundred and fifty-one patients with congenital heart disease less than 24 months old underwent intracardiac repairs from January 1982 to July 1983, which consists 24.2% of all the patients with congenital heart diseases operated during the same period. There were 98 patients[64.9%] with acyanotic congenital heart disease and 53 patients[35.1%] with cyanotic congenital heart disease, and 55 patients[36.4%] were less than 1 year of age. Twenty-two patients died within 30 days after surgery and 3 patients died after postoperative 30th day: Ventricular septal defect, four of 90 patients; Tetralogy of Fallot, five of 23 patients; Transposition of great arteries, nine of 17 patients; Tricuspid atresia, four of 5 patients; Pulmonary atresia, all of 2 patients; Single ventricle, one of single patients. Over all mortality was 16.6% and mortality of acyanotic congenital heart disease, cyanotic congenital heart disease and patients less then 1 year of age was 4.1%, 39.6% and 20.0% respectively. Still the mortality of cyanotic congenital heart disease is high. Careful preoperative evaluation of the detailed intracardiac anatomy and hemodynamics of the patients and proper selection of surgical treatment yield better clinical results.

식도암 환자에서 동시에 일차성 폐암이 발견되는 빈도는 2% 미만에 불과하며, 특히 두 질환 모두 예후가 나쁨으로 인해서 환자들이 근치적 절제술을 받을 기회를 놓치게 되는 경우가 많다. 그러나 환자를 신중히 선택한다면 폐와 식도의 중복암을 동시에 절제함으로써 좋은 결과를 가져올 수 있다고 생각한다. 저자들은 최근 식도와 폐의 일차성 중복암 환자 1예를 경험하였고, 쌍폐엽절제술과 Ivor Lewis 술식으로 일차성 근치적 절제술을 시행하여 좋은 결과를 얻었기에 국내 문헌상으로는 최초로 이를 보고하는 바이다.

Vocal nodule due to vocal hyperfunction is one of the representative chronic diseases of vocal folds, and it can be cured by surgical movement, and/or voice therapy. The present study is, focusing on the latter, to compare the acoustic and aerodynamic results of the pretreatment with those of posttreatment, and then to investigate the objective date on the efficiency of the voice therapy for the patients with vocal nodules. 11 females(age : 7-49) and 5 males(age : 8-40), total 16 patients wi vocal nodules treated by voice therapy were participated as subjects. Six measurements and comparisons of pretreatment and posttreatment of the results were performed : litter, shimmer, and noise-to-harmonic ratio as acoustic analyses ; maximum phonation time, mean flow rate, and the subtraction of mean flow rate from maximum flow rate as aerodynamic analyses. As a result, 14 of 16 subjects showed improvement at more than 4 of 6 measurements, and in group data, every measurements of posttreatment was improved significantly than the pretreatment. On the whole, the improvement of aerodynamic aspects was more statistically significant than that of acoustic ones.

Fine needle aspiration biopsy cytology is a widely recognized and useful technique which can provide diagnosis in lesions of the head and neck, enabling appropriate management plans for individual patient to be made. Fifty one fine needle aspirates from salivary gland masses were examined. Four aspirates (8%) were inadequate for examination. Of the remaning 47 samples, 42 cases (82%) were benign lesions which consist of 30 pleomorphic adenoma(58%), 7 inflammatory lesion (14%), 4 Warthin's tumor(8%) and 1 benign lesion(2%). Two cases(4%) were atypical lesions. Three cases(6%) were malignant lesions consisting of 2 adenoid cystic carcinomas(4%) and 1 mucoepidermoid carcinoma (2%). The cytologic diagnoses were compared with the subsequent histologic diagnosis of surgical resected specimen in 24 cases. 19 cases of 21 aspirates from benign tumors were correctly diagnosed by fine needle aspiration cytology, with a specificity of 90%. All 3 aspirates from the 3 patients with malignant tumor were correctly diagnosed by fine needle aspiration cytology, with a sensitivity at 100%. Overall acurracy was 88%. Diagnostic error was encountered in adenoid cystic carcinoma, mucoepidermoid carcinoma and Warthin's tumor Correct histologic diagnosis was made in 86% of benign tumors(84% for pleomorphic adenoma and 100% for Warthin's tumor) and in 100% of malignant tumors.

Objective : To determine demographic, clinical, health care utilization factors predicting unplanned readmission(within 28 days) to the hospital. Methods : A case-control study was conducted from January to December 2009. Multiple logistic regression was used to examine risk factors for readmission. 180 patients who had been readmitted within 28 days and 1,784 controls were recruited from an university hospital in Seoul. Results : Six risk factors associated with readmission risk were identified and include mail sex, medical service rather than surgical service, number of comorbid diseases, type of patient's room, lenth of stay, number of admissions in the prior 12 months. Conclusions : One of the association with readmission risk identified was the number of hospital admissions in the previous year. This factor may be the only risk factor necessary for assessing prior risk and has the additional advantage of being easily accessible from computerized medical records without requiring other medical record review. This risk factor may be useful in identifying a group at high readmission risk, which could be targeted in intervention studies. Multiple risk factors intervention approach should be considered in designing future prevention strategies.

PURPOSE. The aim of this study was to obtain statistical data on the residual bone height at different natural tooth positions by panoramic radiography in edentulous Korean patients aged 60-90 years. MATERIALS AND METHODS. The study included the diagnostic panoramic radiographs of 180 randomly selected edentulous patients without systemic diseases affecting bone. The radiographic selection criteria included absence of obvious facial asymmetry, clearly visible anatomic structures, and no surgical and fracture history. The panoramic radiographs of 79 patients met these criteria and were used in the analysis. The same researcher processed all the radiographs by using a standardized method. The height of the residual bone was measured at 18 predetermined sites (7 in the maxilla and 11 in the mandible) on digitized and printed radiographs by using a Digimatic caliper, triangle, and ruler. Gender- and age-related differences were statistically analyzed by using the t-test and rank-sum test (${\alpha}=0.05$). RESULTS. The maxillary residual bone height did not show significant gender-related differences, but male patients had significantly higher residual bone in the mandible(P<.05). No significant height differences at the measured sites were noted among the 60s, 70s, and 80s age groups. CONCLUSION. Dentists should pay greater attention to older female edentulous patients because they are more prone to rapid residual bone resorption. Residual bone resorption may not be affected by age.

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare idiopathic inflammatory bone disease characterized by pain and swelling without any detectable infectious factors, the main feature is mild to moderate bone pain. CRMO commonly develops in the metaphyses of long bones and clavicles in children or adolescents. Chronic nonbacterial osteomyelitis (CNO) is the isolated form of CRMO and the etiology of CNO is still unclear. This report describes a rare case of CNO of the mandible in an 8-year-old female patient. On the basis of clinical, histological, and radiological findings, CNO was diagnosed. The patient was asymptomatic after surgical curettage followed by antibiotic therapy. Cone beam CT scan revealed a nearly completed bone healing after three months.

Spontaneous gastric perforation in the newborn is a rare disease that requires early diagnosis and prompt surgical treatment. Between 1988 and 2001 at the Department of Pediatric Surgery. Kyungpool National University Hospital, 9 cases of spontaneous gastric perforation were treated. Seven were males and two females. The mean gestational age and birth weight were 36.7 weeks and 2,455 g respectively. All patients presented with severe abdominal distention and pneumoperitoneum on cross table lateral film of the abdomen. Perforations were located on the anterior wall along the greater curvature of the stomach in six and on the posterior wall along the greater curvature in two. One case showed two sites of perforation on the anterior and posterior wall along the greater curvature. Six patients were managed with debridement and primary closure and the others with debridement and partial gastrectomy. Peritoneal drainage was not performed. There were four deaths; two from sepsis due to leakage from the anastomotic site, one as a result of acute renal failure, and the other by associated respiratory distress syndrome. Spontaneous gastric perforation in the newborn is usually located along the greater curvature. Elevated intragastric pressure is a possible cause of the perforation. Poor prognosis is related to associated diseases and prematurity.
