BACKGROUND The revised ACC/AHA/ESC 2006 guideline recommends either aspirin or warfarin for the prevention of ischemic stroke in patients with atrial fibrillation (AF) in CHADS(2) score 1. We hypothesized that warfarin is superior to aspirin therapy for the prevention of stroke without increasing bleeding complication in AF patients with CHADS(2) score 1.(More)
BACKGROUND atrial tachycardia (AT) commonly recurs within 3 months after radiofrequency catheter ablation for atrial fibrillation (AF). However, it remains unclear whether early recurrence of atrial tachycardia (ERAT) predicts late recurrence of AF or AT. METHODS of 352 consecutive patients who underwent circumferential pulmonary vein isolation with or(More)
BACKGROUND The aim of this study was to assess whether the morphological and functional changes of the left atrium (LA) differ after catheter ablation (ABL) from those after electrical cardioversion (ECV) in atrial fibrillation (AF). METHODS AND RESULTS AF patients who had maintained sinus rhythm for 3 months after either ECV (n=30) or ABL (n=33) were(More)
Inhalation of toxic gases can lead to pneumonitis. It has been known that methane gas intoxication causes loss of consciousness or asphyxia. There is, however, a paucity of information about acute pulmonary toxicity from methane gas inhalation. A 21-year-old man was presented with respiratory distress after an accidental exposure to methane gas for one(More)
OBJECTIVE In order to validate immature granulocytes as a universal biomarker, we have compared the clinical relevance of the proportion of immature granulocytes (IG%), measured using Sysmex XE-2100, with other biomarkers (white blood cell, C-reactive protein, lactate and procalcitonin). METHODS This single center, retrospective study included 184(More)
Chronic necrotizing pulmonary aspergillosis (CNPA) is an unusual form of pulmonary aspergillosis arising in the setting of mildly immune compromised state or altered local defense system. CNPA rarely shows histological findings mimicking bronchocentric granulomatosis (BCG), which is characterized by peribronchiolar granulomatous destruction. We describe a(More)
This study was carried out to investigate the short term toxicity of nine phthalate diesters including di-2 (ethylhexyl) phthalate (DEHP) , di (n-butyl) phthalate (DBP) , di-n-octyl phthalate (DnOP) , diethyl phthalate (DEP) , butylbenzyl phthalate (BBP) , dimethyl phthalate (DMP) , di-isodecyl phthalate (DIDP) , diundecyl phthalate (DUP) , and di-isononyl(More)
Angiomyolipoma is a common tumor of the kidney but has rarely been found in the mediastinum. We report a case of angiomyolipoma of the posterior mediastinum in a 62-year-old woman. She experienced exertional dyspnea and intermittent cough at admission. Computed tomography indicated a tumor located at the left paravertebral and upper posterior mediastinum(More)
We experienced a case of primary pulmonary biphasic synovial sarcoma, which was confirmed by immunohistochemistry and molecular testing of SYT-SSX2 fusion transcripts. The patient was a 61-year-old man who presented with a well-defined mass in the left upper lung field on chest radiography. Left upper lobectomy with lymph node dissection was performed.(More)
The selection of the optimal right ventricular (RV) pacing site remains unclear. We hypothesized that a normal paced QRS axis would provide a physiological ventricular activation and lead to a better long-term outcome. We evaluated 187 patients who underwent a permanent pacemaker implantation and were dependent on RV pacing. The pacing sites were classified(More)
