BACKGROUND: This study quantitatively and qualitatively analyzed the characteristics and trends of papers published in the Journal of the Korean Geriatrics Society. METHODS: Original articles, case reports, review articles published from 2006 to 2013 were retrospectively examined. All of the article research topics, paper-specific corresponding author's affiliations and number of authors were investigated. Original articles were separated and grouped according to research designs. Using the Korean Citation Index, impact factor of this journal was examined and compared with four related journals. RESULTS: Of the 276 articles analyzed, 159 (57.6%) were original articles, 145 (91.2%) were analytic studies, and 36 (22.6%) were experimental studies. The proportion of original articles accounted for about 60% until 2007 but decreased to 41.0% in 2013. By clinical study topics, 37 studies (13.4%) addressed the understanding of geriatric diseases and 45 studies (16.3%) were focused on nervous system diseases. The median number of authors for the 276 studies was 6. Internal medicine accounted for the largest proportion of corresponding author's affiliation (109 studies, 39.5%) studies. Impact factor of the journal increased from 0.05 (4th position) in 2009 to 0.48 (3rd position) in 2011. CONCLUSION: Articles published in the Journal of the Korean Geriatrics Society increasingly included experimental studies based on evidence-centered medicine, with the proportion of original articles decreasing. The impact factor increased annually along with the journal ranking, compared with other journals. Journal of the Korean Geriatrics Society is judged to be qualitatively improving.

A 76-year-old man with no notable medical history was scheduled for a robot-assisted radical prostatectomy. After the operation, he was given sugammadex. Two minutes later, ventricular premature contraction bigeminy began, followed by cardiac arrest. Cardiac arrest occurred three times and cardiopulmonary resuscitation was done. The patient recovered after the third cardiopulmonary resuscitation and was transferred to the intensive care unit. Coronary angiography was done on postoperative day 1. The patient was diagnosed with variant angina and discharged uneventfully on postoperative day 8.

Background: An accurate diagnosis in patients with interstitial lung diseases (ILDs) by multidisciplinary discussion (MDD) based on histopathologic information is essential for optimal treatment. Transbronchial lung cryobiopsy (TBLC) has increasingly been used as a diagnostic alternative to surgical lung biopsy. This study aimed to evaluate the appropriate methods of TBLC in patients with ILD in Korea. Methods: A total of 27 patients who underwent TBLC were included. TBLC procedure details and clinical MDD diagnosis using TBLC histopathologic information were retrospectively analyzed. Results: All procedures were performed under general anesthesia with the fluoroscopic guidance in the operation room using flexible bronchoscopy and endobronchial balloon blocker. The median procedure duration was less than 30 minutes, and the median number of biopsies per participant was 2. Most of the bleeding after TBLC was not severe, and the rate of pneumothorax was 25.9%. The most common histopathologic pattern was alternative (48.2%), followed by indeterminate (33.3%) and usual interstitial pneumonia (UIP)/probable UIP (18.5%). In the MDD after TBLC, the most common diagnosis was idiopathic pulmonary fibrosis (33.3%), followed by smoking-related ILD (25.9%), nonspecific interstitial pneumonia (18.6%), unclassifiable-ILD (14.8%), and others (7.4%). Conclusion This first single-center experience showed that TBLC using a flexible bronchoscopy and endobronchial balloon blocker with the fluoroscopic guidance under general anesthesia may be a safe and adequate diagnostic method for ILD patients in Korea. The diagnostic yield of MDD was 85.2%. Further studies are needed to evaluate the diagnostic yield and confidence of TBLC.
