Why do more intelligent people live healthier and longer lives? One possibility is that intelligence tests assess health of the brain, but psychological science has lacked technology to evaluate this hypothesis. Digital retinal imaging, a new, noninvasive method to visualize microcirculation in the eye, may reflect vascular conditions in the brain. We studied the association between retinal ves...

Nine children with chronic post-traumatic dislocation of the head of the radius were treated by an osteotomy of the ulna with over-correction of the angular deformity and with elongation of the bone. Satisfactory results were obtained in eight cases, the only poor outcome following a three-year delay between the initial injury and the reposition. The interosseous membrane of the forearm appeare...

Caliber-persistent artery (CPLA) of the lip is a common vascular anomaly in which a main arterial branch extends to the surface of the mucous tissue with no reduction in its diameter. It usually manifests as pulsatile papule, is easily misdiagnosed, and is observed more frequently among older people, suggesting that its development may involve a degenerative process associated with aging; CPLA ...

Materials and methods The reconstructed site was the humerus in 15 cases, the radius, the ulna or the wrist joint in 22 cases, carpal or metacarpal bone in 52. The etiologies consisted of three traumatic bone defects, 13 traumatic nonunions of long bone, two osteonecroses of the humeral head, eight osteomyelitis, nine case after resections of bone tumor, two congenital pseudoarthroses of the ul...

Two consecutive cases of chronic dislocation of the head of the radius after missed Bado type-I Monteggia lesions are presented. Reduction was successfully achieved in both patients after ulnar corticotomy, gradual lengthening and angulation of the ulna using an external fixator. Open reduction or reconstruction of the radio-ulnar capitellar joint was not undertaken. The age at injury was seven...

Congenital proximal radioulnar synostosis (PRUS) is a rare congenital anomaly where the radius and ulna are fused at the proximal portion which can cause the rotation of the forearm to be restricted (Fig.1). Bilateral pronation ankylosis over sixty degrees can restrict the patient’s daily activities. According to the position of the radius head in x-ray, PRUS is classified into three types, pos...

Subluxation or dislocation of the distal radio-ulnar joint has been regarded as one of the rarer complications after fracture of the head of the radius. Brockman (1930) and Essex-Lopresti (1950) each reported two cases, and Essex-Lopresti recalled that Murray (1940) had found no obvious wrist changes in 459 such fractures, Burton (1942) none in fifty, and Gaston, Smith and Baab (1949) none in 1...
