The vascular effects of endothelin-1 (ET) in humans were investigated by brachial artery infusions of ET into 25 healthy volunteers. Forearm blood flow increased from a mean±SD value of 2.3± 1.5 to 2.5± 1.5 ml/min/100 ml forearm tissue (n=25, p<0.05) in response to low dose (0.5 ng/min/100 ml forearm tissue) ET infusion and decreased to 1.78±1.3 and 1.1±0.9 ml/min/100 ml forearm tissue (p<0.001...
1. Hypoxia, induced by 7-12% oxygen breathing, produced vasodilatation in the intact or in the phenoxybenzamine and propranolol treated forearm of human volunteers when arterial blood POz decreased below 45 mmHg, or when deep forearm venous blood PO, decreased below 3540 mmHg. 2. Circulatory arrest of the forearm following alpha and beta adrenergic receptor blockade was followed by greater incr...
BACKGROUND Forearm fractures affect 1.7 million individuals worldwide each year and most occur earlier in life than hip fractures. While the heritability of forearm bone mineral density (BMD) and fracture is high, their genetic determinants are largely unknown. AIM To identify genetic variants associated with forearm BMD and forearm fractures. METHODS BMD at distal radius, measured by dual-...
Patients frequently present with deformity of forearm with bone loss in either of the forearm bones due to various reasons. In this study two children suffering from chronic osteomyelitis and one having neglected Monteggia fracture were selected. In all three cases, single bone forearm reconstruction by radioulnar fusion was attempted successfully. Cosmetic and functional outcomes were evaluate...
The case of a eleven-year-old girl who had a fracture dislocation of the left elbow with entrapment of the ulnar nerve into the dislocated ulnar epicondyle anlage and unstable forearm fracture of the ipslateral upper extremity is described. This severe injury to the elbow and the ipsilateral forearm is termed "floating forearm" injury. The forearm was stabilized percutaneously and the elbow fra...
The effect of intra-arterial and intravenous epinephrine on skeletal muscle blood flow and metabolism were studied in the human forearm following complete suppression of the circulation to forearm skin by epinephrine iontophoresis. Epinephrine by either route of administration increased blood flow, O., consumption and CO;> production, and decreased arteriovenous differences of O., and CO2 acros...
INTRODUCTION Osteomyelitis of the radius resulting in the radial clubhand is a very rare condition and few studies have been published about its prognosis and treatment. CASE OUTLINE This is a case report of hematogenous osteomyelitis of the radius with a complete loss of the radius leaving only the distal radial metaphysis to carry the carpus. In order to achieve best functional results, fou...
Seven fresh cadaveric specimens were used to determine the loss of forearm rotation with varying distal radius fracture malalignment patterns. Uniplanar malunion patterns consisting of dorsal tilt, radioulnar translation, or radial shortening were simulated by creating an osteotomy at the distal end of the radius, orienting the distal fragment position using an external fixator, and maintaining...
