In the Pediatric Dentalc profession the occurrence rate intrusion of young permanent teeth is rather low, and the treatment method varies from one another. Intrusion of the teeth bring complications to the pulp and periodontal ligament, and thus the possibility of endodontic treatment increases. For the formation of calcific barriers, calcium hydroxide is used in young permanent teeth and this makes the final canal filling possible. In this case report, we will show two cases of young permanent teeth intrusion and the treatment methods to help assess the recognition of treatment for young permanent teeth intrusion.

심장 외 인공도관 폰탄 술식을 시행한 선천성 심장병 환자에서 도관 천자를 통하여 정맥을 통한 인공 심박동기 삽입을 한 증례는 아직 보고된 바가 없다. 결론적으로 본 증례와 같이 심장 외 인공도관 폰탄 수술을 시행 받은 환자에서도 안전하고 효과적으로 정맥을 통해 인공 심박동기를 삽입하는 것이 가능하리라 생각된다. As the survival rate of patients with complex congenital heart disease has improved and the number of adult patients with congenital heart disease has risen, arrhythmias and heart failure have become important issues in these patients. Cardiac implantable electronic devices, including pacemakers, are also on the rise. Transvenous implantation or epicardial pacemaker implantation is challenging in patients with complex congenital heart disease. Here we report a case in which a dual-chamber pacing, dual-chamber sensing, dual response and rate-adaptive (DDDR) pacemaker was implanted transvenously into a patient with congenital heart disease. A 34-year-old male with extracardiac conduit Fontan circulation complained of dizziness; an electrocardiogram revealed junctional bradycardia. We performed transvenous implantation of a DDDR pacemaker via trans-conduit puncture. In conclusion, transvenous implantation of a pacemaker is feasible in patients with extracardiac conduit Fontan circulation. (Korean J Med 2015;88:299-302)

The purpose of this study was to compare the microleakage pattern of glass ionomer with resin restoration in microleakage pattern of primary and permanent teeth. Micreoscopical observation of interface between tooth structure and restoration was also performed. 80 and 8 sound molar teeth were used for the microleakage test and SEM study respectively. Data were analyzed statistically using ANOVA test and/or t-Test. The results of the present study were as follows: 1. According to the result of microleakage pattern between primary and permanent tooth, primary tooth generally showed more microleakage than permanent tooth in all groups(p<.05). 2. In the resin-filled groups, occlusal margin was shown to have more micreliakage than gingival margin(p<.05). Whereas the glass ionomer-filled groups showed no statestically significant differences between them(p>.05). 3. No statistically significant differences in microleakage could be found between two different resin groups(p>.05). while FujiⅡ LC group showed less microleakage than Ketac-Fil group(p>.05). 4. The various type hybrid layer was evident under SEM in resin-filled groups both in primary and permanent teeth with generally thicker layer in primary group. Among glass-ionomer group, FujiⅡ LC group showed more intact adhesion to tooth surface than Ketac-Fil group.

We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

Background: Severe acute exacerbations (AEs) of chronic obstructive pulmonary disease (COPD) are associated with a more rapid decline in lung function, poor quality of life, considerable mortality, and high socioeconomic burden. Objective: We aimed to investigate risk factors associated with frequent severe AEs in COPD patients. Methods: A retrospective observational study was performed in 80 patients who experienced severe AE between February 2012 and January 2014 and had one-year follow-up from the first admission day. Results: Of 80 patients, 32 patients (40.0%) experienced frequent AEs (≥2 severe exacerbations over one year) and half of them experienced subsequent event within 90 days. Frequent severe AEs were associated with bronchial asthma, hypertension, poor lung function, home oxygen therapy and oral steroid medication, while subsequent severe AEs within 90 days after initial episode were related with bronchial asthma, poor lung function and home oxygen therapy. In multivariate analysis, home oxygen therapy (P = 0.025), low baseline FEV1 (P = 0.035), high CRP (P = 0.020), high body mass index (P = 0.005) and low eosinophil count (P = 0.049) were associated with frequent severe AEs, while bronchial asthma (P = 0.027) and home oxygen therapy (P = 0.040) were associated with early subsequent severe AEs. Conclusion: The present study showed impact of concomitant bronchial asthma on early subsequent severe AE and found that severity-related factors of underlying disease was associated with frequents severe AE over one year in COPD patients.
TP-43 : 응급실로 내원한 폐렴 환자에 대한 중증도 평가에 있어서 응급실 주치의와 호흡기내과 전임의 사이의 일치도

배경: 폐렴환자에 대한 중증도 평가는 치료 방향 결정 및 예후 평가에 있어서 중요하며 흔히 Pneumonia Severity Index (PSI)와 CURB-65 (confusion, urea, respiratory rate, blood pressure, age 65)를 사용한다. 하지만 응급실에서 일차적으로 진료하는 전공의들의 폐렴 중증도 평가 정도와 정확도에 대하여 알려진 바는 없다. 방법: 2011년 4월에서 2012년 12월 사이에 삼성서울병원 응급실을 통하여 입원한 폐렴환자를 대상으로 응급실 전공의들의 폐렴 중증도 평가 정도를 전향적으로 관찰하고 호흡기내과 전문의의 평가와 일치도를 확인하였다. 결과: 연구기간 동안 응급실을 통해 입원한 513명의 폐렴 환자 중 응급실 전공의가 폐렴 중증도를 평가한 경우는 PSI, CURB-65 각각 27%, 26%에 불구하였다. 중증도가 평가되지 않은 환자의 경우 중증도가 평가된 환자에 비하여 PSI 점수가 높고(105±41 vs 92±36, P=0.001), 의료기관관련 폐렴이 흔하였지만(122/376 [32%] vs 31/137 [23%], P=0.031), 병원 사망률에는 차이가 없었다(27/376 [7%] vs 11/137 [8%], P=0.745). 호흡기내과 전문의에 의한 중증도 평가와 비교 시 PSI class는 카파값 0.419이었으나, CURB-65 점수는 카파값 0.625이었다. 특히 PSI의 경우는 심장질환 여부, 중추신경계질환 여부, 흉수 동반 여부에 대한 항목에서 CURB-65는 의식저하 여부에 대한 항목에서 일치도가 낮았다. 결론: 응급실에서 일차적으로 진료하는 전공의들은 입원이 필요한 폐렴 환자의 약 1/4 정도에서만 중증도를 평가하고 있으며, 특히 중증 환자일수록 평가 정도가 낮았다.

Citation analyses aid in assessing quality, trends, and future directions of research fields. We aimed to identify the most influen-tial articles on infections caused by nontuberculous mycobacteria (NTM) in the last 20 years. We performed a cited reference search of the database Web of Science from 1995 to 2015. The 100 most-cited articles on NTM infections were analyzed. The top 100 articles were cited from 114 to 1,471 times and were published from 1995 to 2013. Sixty-five were laboratory-based, basic science articles, with the major topics being pathophysiology (n = 20) and molecular methods for NTM identification (n = 15). Among the 35 non-laboratory studies, major topics were clinical management (n = 15) and epidemiology (n = 14). The top article was a clinical treatise on the management of NTM disease published in 2007. Although there was a correlation between article rank and journal impact factor (P = 0.043, rho = -0.202), the five articles from the journals with highest impact factors did not rank within the top 10 articles. In conclusion, a large proportion of influential articles on NTM infection are basic scientific studies, and the most influential articles are not always published in high-impact journals.
