OBJECTIVE Major side effects after endovenous laser ablation (EVLA) are pain and bruising. The aim of this study was to compare outcome and side effects after EVLA for primary varicose veins with 1470 nm diode laser using bare-tip orradial fiber. METHODS From October 2007 to December 2010, 385 patients (453 limbs) with primary varicose veins treated with 1470 nm laser were studied. Bare-tip f...

abstract background: distal radial fracture is one of the most common fractures of the skeletal system. although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. the goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extra...

BACKGROUND Surgical excision of the radial head is frequently required after a comminuted fracture of the radial head. The outcome of this procedure is often unpredictable, with some patients experiencing ulna-sided pain in the wrist secondary to proximal migration of the radius. Insertion of a radial head prosthesis could prevent proximal radial migration and restore normal load-sharing at the...

A weakly charged flexible polyelectrolyte chain in a neutral spherical cavity is analyzed by using self-consistent field theory within an explicit solvent model. Assuming the radial symmetry for the system, it is found that the confinement of the chain leads to creation of a charge density wave along with the development of a potential difference across the center of cavity and the surface. We ...

The radiation environment on board the space shuttle and the International Space Station includes high-Z and high-energy (HZE) particles that are part of the galactic cosmic radiation (GCR) spectrum. Iron-56 particles are considered to be one of the most biologically important parts of the GCR spectrum. Tissue-equivalent proportional counters (TEPCs) are used as active dosimeters on manned spac...

BACKGROUND In the past, radial head resection was the surgical treatment of choice for radial head fractures that could not be internally fixed. More recently, radial head implant arthroplasty has gained popularity for the treatment of isolated radial head fractures. The purpose of the present study was to review the long-term results of radial head resection after radial head fractures not ass...
