We report a neonatal case of “intraluminal” pyloric duplication cyst, causing gastric obstruction after birth. Endoscopy revealed a submucosal cystic lesion approximately 15 mm in size arising from the anterior and inferior surfaces of the pylorus obliterating the pyloric canal. After laparotomy, intraoperative cholangiography was performed, which documented no communication between the cyst and the bilio-pancreatic duct. Gastrotomy was performed transversally over the antrum, and the cyst delivered through the incision. The cyst was incised, the upper part of the cyst wall removed, and a mucosectomy performed on the inner cyst wall of the lower part. The mucosa and muscle of the margin of the cyst were approximated. At follow up of 10 months, the patient is well without any sign of gastric obstruction.

Introduction: Conference presentations are a very instructive experience for doctors.Aim: The aim of this study was to evaluate residents' attitude toward conference presentations.Methods: A questionnaire-based survey was conducted on 22 residents at our hospital, regarding their experience with giving a conference presentation.Results: Of the 22 residents, 15 (68%) completed the questionnaires. 13 (87%) of them had experienced giving a presentation for the first time. Overall, 14 (93%) of the 15 residents thought the experience of giving a conference presentation was very instructive. 12 residents (80%) wanted to experience it again. On the other hand, a few residents requested that giving a presentation be made voluntary and not mandatory.Conclusion: The results of our study demonstrates that giving conference presentations would be a very valuable experience for young doctors. The experience of giving a presentation coupled with prior explanations about its instructive value could positively impact intrinsic motivation.

PURPOSE: Dexrazoxane has been used as an effective cardioprotector against anthracycline cardiotoxicity. This study intended to analyze cardioprotective efficacy and secondary malignancy development, and elucidate risk factors for secondary malignancies in dexrazoxane-treated pediatric patients. MATERIALS AND METHODS: Data was collected from 15 hospitals in Korea. Patients who received any anthracyclines, and completed treatment without stem cell transplantation were included. For efficacy evaluation, the incidence of cardiac events and cardiac event-free survival rates were compared. Data about risk factors of secondary malignancies were collected. RESULTS: Data of total 1,453 cases were analyzed; dexrazoxane with every anthracyclines group (D group, 1,035 patients) and no dexrazoxane group (non-D group, 418 patients). Incidence of the reported cardiac events was not statistically different between two groups; however, the cardiac event-free survival rate of patients with more than 400 mg/m2 of anthracyclines was significantly higher in D group (91.2% vs. 80.1%, p=0.04). The 6-year cumulative incidence of secondary malignancy was not different between both groups after considering follow-up duration difference (non-D, 0.52%±0.37%; D, 0.60%±0.28%; p=0.55). The most influential risk factor for secondary malignancy was the duration of anthracycline administration according to multivariate analysis. CONCLUSION: Dexrazoxane had an efficacy in lowering cardiac event-free survival rates in patients with higher cumulative anthracyclines. As a result of multivariate analysis for assessing risk factors of secondary malignancy, the occurrence of secondary malignancy was not related to dexrazoxane administration.
