We read with interest the Editorial published recently, entitled “The transforming face of fracture epidemiology” (1). The author has rightly pointed out the facts regarding the nonfatal patterns of skeletal fractures, which include the fractures induced by the restraint system like air bags and frontal motor vehicle collisions (2, 3). The various modification in designing of such light motor v...

Populations of isolated brain capillaries have been proposed as useful models for in vitro studies of the blood-brain barrier. Preliminary investigations of barrier properties using such preparations of brain microvessels have suggested that the tight interendothelial junctions (zonulae occludentes) are intact and retain the impermeability to the protein tracer horseradish peroxidase, exhibited...

BACKGROUND AND AIM This study aims at evaluating the reliability on specific multi-planar cone beam computer tomography (CBCT) reconstruction in the orbital floor fractures. METHODS CBCT examination of the mid-face fractures area involving the floor of the orbit was performed in a number of 93 trauma patients by two independent radiologists. Both radiologists assessed the axial, coronal and s...

Un garçon de 14 ans se présente aux urgences pour une impotence fonctionnelle douloureuse de l'avant bras droit à la suite d'une chute de sa bicyclette. L'examen clinique initial a montré un avant bras tuméfié avec une vive douleur au tiers moyen sans déficit vasculaire ou nerveux. Les diagnostics à évoquer sont une fracture du radius ou de l'ulna ou des deux os de l'avant bras. La radiographie...

The brittle fracture of a gypsum cylinder, which is used as an artificial kidney stone in lithotripsy research, is simulated by the use of the finite element method. The cylinder is submerged in water and is subjected to a pressure front parallel to one of its planar faces. The stresses induced by the pressure wave lead to fracture in the interior of the cylinder, with the formation of a spall ...

Congenital dyserythropoietic anemia type II (CDA II or HEMPAS) is a genetic anemia caused by membrane abnormality. Our previous studies indicated that in HEMPAS, erythrocytes band 3 and band 4.5 are not glycosylated by polylactosaminoglycans. The present study was aimed at determining how such underglycosylated band 3 behaves in erythrocyte membranes. By using anti-band 3 antibodies, immunogold...

Trauma to anterior teeth is common and requires accurate diagnosis and thorough treatment planning. The maxillary incisors are often affected during injury to the face because of their normal labial projection inflicting damage to the crowns. Multidisciplinary treatment approach is important for aesthetic and functional rehabilitation of anterior teeth with crown fracture. The purpose of this a...

We introduce here a technique, "label-fracture," that allows the observation of the distribution of a cytochemical label on a cell surface. Cell surfaces labeled with an electron-dense marker (colloidal gold) are freeze-fractured and the fracture faces are replicated by plantinum/carbon evaporation. The exoplasmic halves of the membrane, apparently stabilized by the deposition of the Pt/C repli...

Condylar fractures are among the most frequent fractures in the context of traumatic lesions of the face. The management of condylar fractures is still controversial, especially when fractures occur in children: if overlooked or inappropriately treated, these lesions may lead to severe sequelae, both cosmetic and functional. The therapy must be careful because severe long-term complications can...

BACKGROUND AND PURPOSE Conventional thinking among radiologists is that the mandible acts as a closed "ring" that needs to fracture at 2 points, though the frequency of multiple mandible fractures has been reported to be only as high as 67%. However, many of these studies did not use CT to confirm the presence of suggested fractures and excluded nondisplaced fractures. The purpose of this study...
