SETTING AND STUDY PARTICIPANTS We used a database from the(More)
Blind needle puncture of the subclavian vein, which is the standard method used for insertion of pacemaker electrodes, causes an increased risk of lead fractures due to entrapment of the lead by the costoclavicular ligament and/or subclavius muscle. The extrathoracic lead insertion technique was developed to prevent such lead fractures. The present study(More)

Over the last decade in Japan, laparoscopic cholecystectomy (LC) has replaced traditional open cholecystectomy as the standard of elective surgery for cholelithiasis. The laparoscopic approach has a clinical course relatively easier to standardize among the different types of intraabdominal surgery. However, significant practice variation is suspected in(More)
A 56-year-old man who complained of quadrantic hemianopsia was admitted to determine its etiology. Cerebral angiography revealed no organic stenosis. Echocardiography showed clear direct continuity between a hypertrophied anterolateral papillary muscle and the anterior mitral leaflet, and the left ventricular (LV) outflow tract (LVOT) was narrowed by the(More)
UNLABELLED Transmesenteric hernia is a rare cause of small bowel obstruction and is seldom diagnosed preoperatively, partly because of unfamiliarity with this type of internal hernia. The clinical symptoms of internal hernia may be intermittent and nonspecific, making the diagnosis extremely difficult. We report two patients, 7- and 5-year-old girls, with(More)
Transthoracic echocardiography is useful for evaluation of the coronary arteries in infants and children with Kawasaki disease. In adults, however, transthoracic echocardiography often cannot detect or accurately estimate coronary artery lesions. We describe two young adults admitted for a diagnosis of acute myocardial infarction ascribed to Kawasaki(More)
