Deep burns of the face & lips often lead to scarring and contraction of the circum-oral tissues with a marked reduction in the size of the oral aperture. Such burns most commonly caused by electrical contact, for example, children sucking electric plugs, or as a result of chemical burns and the exposture to flame. Once having burns, burned tissue may contract and reduce considerably the size and mobility of the mouth ; therefore bring up the resultant functional disturbance, verbal difficulty, even disgestive difficulty, and poor appearance, which fall into difficulty in social acceptability, caused by burns. In our department, 2 patients who were complain of functional limitations and esthetic problem owing to scar contracture, were visited, and we treated this microstomia with scar excision, graft and flap technique, and postoperative intensive physical therapy. We obtained relatively favorable results, thus report this cases with literature review.

본 논문은 학교현장에서 학습자의 창의력 신장을 위해 멀티미디어 교육을 지원하는 웹 기반 실시간 교육 시스템을 제안하였다. 제안된 시스템은 교수·학습자간의 실시간 상호작용과 개별학습, 학습자의 학습일탈을 방지하기 위한 강제화면 분배를 지원할 수 있게 설계되었다. 본 시스템은 UML을 적용하여 다중 사용자 환경에서의 실시간 메시지 교환과 관리를 위한 모듈을 두어 효율적인 상호작용이 가능하게 하였으며, 학습자의 실험·실습을 위한 시뮬레이션이 이루어지고 실험의 방법과 결과분석 등에 대한 질의 응답을 지원한다. 학습자의 학습진행과 지식형성을 위해 시스템의 교육적 기반을 구성주의에 두었다. In this paper a web-based real-time education system, which is able to support education through multimedia, is suggested for the expansion of learner's creative ability in the school. This system is designed so that it can support three things: 1) a real time interaction between instructors and learners, 2) individual learning through such an interaction, and 3) a coercive distribution of display by instructions for preventing the deviation of learners from learning. Also, this system, which UML is applied to, makes efficient interaction possible through the module for the real-time exchange and management of messages even in the multi-user environment. Through this system, not only the simulation by learners can be made for experiments and practices, but also questions and respondence can be supported on the procedure of experiments and the analysis of their results. This system is built on constructivism, and aimed at helping the learning progress and knowledge formation of learners.

Background: This study evaluates the bacterial pathogens of Ventilator-associated pneumonia (VAP) in a tertiary referral hospital. Methods: A total of 109 bacterial pathogens from 91 adult patients with VAP, who were admitted to the medical intensive care unit from January 2008 to December 2009, were examined. Clinical characteristics, bacterial pathogens, and resistance profiles were analyzed. Results: Staphylococcus aureus (44%) was the most frequently isolated. Acinetobacter baumanii (30%), Pseudomonas aeruginosa (12%), Stenotrophomonas maltophilia (7%), Klebsiella pneumoniae (6%), and Serratia marcescens (2%) were isolated from the transtracheal aspirates or bronchoalveolar lavage in patients with VAP. There was no significant difference of bacterial pathogens between early and late onset VAP. All isolated S. aureus were methicillin resistant S. aureus; the imipenem resistance rate of A. baumanii was 69%. Conclusion: The two most frequent pathogens of VAP were S. aureus and A. baumanii. There were no pathogenic differences between early and late onset VAP.

Bronchiolitis interstitial pneumonitis (BIP), an unclassified and newly described interstitial pneumonia, has a combined feature of prominent bronchiolitis, interstitial inflammation, and fibrosis. It is distinct from bronchiolitis obliterans or bronchiolitis obliterans organizing pneumonia (BOOP). BIP has a better prognosis than common cases of interstitial pneumonia. However, BIP has a poorer prognosis than BOOP. BIP`s response to corticosteroids is not as successful as BOOP`s response to this treatment. We encountered the case of a 31-year-old woman with BIP with an initial presentation of dyspnea and a cough that had lasted for 3 months. The patient`s chest CT scan demonstrated patchy ground glass opacities and multiple ill-defined centrilobular nodules in both lungs, suggesting military tuberculosis or nontuberculous mycobacterial infection. A video-assisted thoracoscopic lung biopsy resulted in the diagnosis of BIP. Clinical symptoms, pulmonary lesions, and pulmonary function tests were improved after oral glucocorticoid therapy.

Factitious hemoptysis is the bleeding type of Munchausen`s syndrome, and this describes a group of patients who intentionally produce symptoms. Because factitious hemoptysis is a very rare manifestation of hemoptysis, it generally passes unnoticed. We report here on a case of factitious hemoptysis in a 15-year-old boy who presented with hemoptysis. During his three hospitalizations, we conducted many diagnostic procedures, including chest CT, laryngoscopy, bronchoscopy and bronchial arteriography, yet we failed to find the definitive cause of the patient`s hemoptysis. He kept on complaining of repetitive hemoptysis and seizure-like activity. His father discovered that he had collected his blood into the specimen cup via an intravenous line. After we removed the intravenous line, he did not show blood to us again. We suggest that factitious hemoptysis should be considered in the differential diagnosis of hemoptysis of an unclear bleeding focus, and especially when the patient has a bizarre hospital course or unusual behavior. We also include a review of the relevant literature. (Tuberc Respir Dis 2008;65:396-399)

Background/Aims: The frequency of nontuberculous mycobacteria pulmonary disease in HIV-negative patients is increasing; the most common pathogen in Korea is the Mycobacterium avium complex (MAC). However, few studies have evaluated the treatment outcome of MAC pulmonary disease in Korea. Methods: The efficacy of a clarithromycin-containing regimen for MAC pulmonary disease was studied in 42 patients treated for more than 6 months between January 2005 and December 2008. All patients were treated with a regimen consisting of clarithromycin, rifampin, and ethambutol. Streptomycin was added in 10 patients. Results: Among the 42 patients, a negative culture conversion was achieved in 33 (78.6%), and the median duration of treatment in these patients was 19 months (interquartile range [IQR], 16 to 22). Of the 33 patients with a negative culture conversion, 14 completed treatment. During the follow-up period (median, 10 months; IQR, 4 to 20) for the 14 patients, one relapsed at 24 months after treatment completion. The culture conversion rate was significantly higher in patients who were treated with more than 500 mg/day clarithromycin (87.1% vs. 54.5%, p = 0.038). Conclusions: The combined regimen including clarithromycin was effective against MAC pulmonary disease. High-dose clarithromycin of more than 500 mg/day may improve the outcome of patients with MAC pulmonary disease. (Korean J Intern Med 2011;26:54-59)

Background: Beyond its current function as a rescue therapy in acute respiratory distress syndrome (ARDS), extracorporeal membrane oxygenation (ECMO) may be applied in ARDS patients with less severe hypoxemia to facilitate lung protective ventilation. The purpose of this study was to evaluate the efficacy of extended ECMO use in ARDS patients. Methods: This study reviewed 223 adult patients who had been admitted to the intensive care units of 11 hospitals in Korea and subsequently treated using ECMO. Among them, the 62 who required ECMO for ARDS were analyzed. The patients were divided into two groups according to pre-ECMO arterial blood gas: an extended group (n=14) and a conventional group (n=48). Results: Baseline characteristics were not different between the groups. The median arterial carbon dioxide tension/ fraction of inspired oxygen (FiO<sub>2</sub>) ratio was higher (97 vs. 61, p<0.001) while the median FiO<sub>2</sub> was lower (0.8 vs. 1.0, p<0.001) in the extended compared to the conventional group. The 60-day mortality was 21% in the extended group and 54% in the conventional group (p=0.03). Multivariate analysis indicated that the extended use of ECMO was independently associated with reduced 60-day mortality (odds ratio, 0.10; 95% confidence interval, 0.02-0.64; p=0.02). Lower median peak inspiratory pressure and median dynamic driving pressure were observed in the extended group 24 hours after ECMO support. Conclusion: Extended indications of ECMO implementation coupled with protective ventilator settings may improve the clinical outcome of patients with ARDS.
