Bone strength and structure are closely associated with fracture and screw fixation, however osseous micro architecture on scaphoid has not been clearly addressed. We conducted histomorphometric study of the scaphoid using micro CT to find regional variations and differences in the scaphoid to provide better understanding of fracture mechanism and suggest(More)
BACKGROUND It is unknown whether physicians' attitudes about the management of atrial fibrillation (AF) reflect the recommendations of published guidelines. METHODS To obtain information about physicians' attitudes about management of AF, a questionnaire was returned by 904 (20.1%) of 4500 physicians involved in managing AF (385 cardiologists, 326(More)
OBJECTIVE This study aims to evaluate perioperative mortality and morbidity after total hip replacement in liver transplant recipients and suggesting safety guidelines. BACKGROUND Hip replacement surgery is one of the most common elective surgeries even for organ transplant recipients. However, there is a paucity of literature addressing the morbidity and(More)
BACKGROUND Human alpha(2)-antiplasmin (alpha(2)AP), the primary inhibitor of fibrinolysis, is secreted from the liver into plasma as a 464-residue protein with Met as the N-terminus. An R6W polymorphism has been suggested to affect fibrinolytic rate. Within circulating blood, antiplasmin-cleaving enzyme (APCE) cleaves Met-alpha(2)AP(R6) faster than(More)
The value of dobutamine echocardiography and resting thallium-201 scintigraphy to predict reversal of regional left ventricular wall motion dysfunction after revascularization in patients with chronic coronary artery disease was assessed. Improvement in wall motion during dobutamine echocardiography and normal or mildly decreased uptake on thallium-201(More)
Adenosine has become the preferred treatment for common types of supraventricular tachycardia because it is extremely effective and rarely associated with with serious side effects. It has also been advocated as an intervention for diagnostic use to assess uncommon types of tachycardia. Evidence is shown in this report that adenosine was associated with(More)
While all patients with atrial fibrillation should receive anticoagulation and control of ventricular response, it is not clear whether conversion to sinus rhythm is associated with a good long-term outcome. Data are presented detailing current physician practices regarding conversion to sinus rhythm (preferred by 90%) and why participation in the new(More)
BACKGROUND Optimal surgical treatment of unstable distal clavicle fractures is controversial, and various fixation options are available. The objective of this study was to evaluate a new modified tension band fixation technique for unstable distal clavicle fractures. METHODS Forty-two patients with acute unstable distal clavicle fractures were managed(More)
