OBJECTIVES This study examined the association of resource use with comorbidity status and patient age among hip fracture patients who underwent surgical treatment. DESIGN We used a database from the Voluntary Hospitals of Japan Quality Indicator Project that involved 10 privately owned leading teaching hospitals in Japan. SETTING Four of these(More)
Oxygen dynamics were measured in both sides of the paraspinal muscles of patients with degenerative lumbar scoliosis. The objective was to investigate the extent of stress by measuring the changes in oxygenation and blood flow volume using near-infrared spectroscopy. There were 44 patients with degenerative lumbar scoliosis (7 men, 37 women) and 11 controls(More)
Sirs, We read with great interest the article entitled “Acute renal failure due to obstructive uric acid stones associated with acute gastroenteritis” by Fujita et al. that was recently published in Pediatric Nephrology [1]. Here, we would like to comment on the pathogenesis of uric acid stone formation in children with human rotavirus (HRV)-associated(More)
OBJECTIVE We assessed variations in the use of breast conserving surgery (BCS) for operable breast cancer paticnts among hospitals in Japan, and then compared the length of stay (LOS) and total charges during hospitalization between patients who received BCS and those who received mastectomy. SETTING AND STUDY PARTICIPANTS We used a database from the(More)
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 mesenteric(More)
Blind needle puncture of the subclavian vein, which is the standard method used for insertion of pancemaker 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)
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)
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)
