MM is frequently associated with the development of osteolytic bone lesions, osteoporosis and pathological fractures. Bone destruction in MM is caused by osteoclasts recruited in areas adjacent to myeloma plasma cells; their contact triggers both cell types to secrete soluble factors sustaining one each other's activation and proliferation. Osteoclasts(More)
BACKGROUND The Rib Index, (RI), extracted from the double rib contour sign (DRCS) on lateral spinal radiographs to evaluate rib hump deformity, (RHD), in idiopathic scoliosis, (IS), patients, has been previously introduced. Although various papers using the RI have been published, no study on its reproducibility has been reported. The aim of this report is(More)
The increased incidence of motor vehicle accidents during the past century has been associated with a significant increase in brachial plexus injuries. New imaging studies are currently available for the evaluation of brachial plexus injuries. Myelography, CT myelography, and magnetic resonance imaging (MRI) are indicated in the evaluation of brachial(More)
The incidence of brachial plexus injuries is rapidly growing due to the increasing number of high-speed motor-vehicle accidents. These are devastating injuries leading to significant functional impairment of the patients. The purpose of this review paper is to present the available options for conservative and operative treatment and discuss the correct(More)
Objectives Idiopathic scoliosis (IS) is a 3D deformity of the trunk with detectable bony asymmetries and deformities not only of the spine-the central axis-but also of the rib cage and other parts of the body. The thorax, like any other part of the skeleton displays variations in dimensions and proportions. The bony framework of the thorax changes so that(More)
BACKGROUND Review of literature reveals that in Idiopathic Scoliosis (IS) children, the post-operative rib hump (RH) correction using full transpedicular screw construct has never been compared to hybrid constructs, applying the Rib-Index (RI) method. Therefore the aim of this report is to study which of the above two constructs offers better postoperative(More)
Objectives The Rib Index, (RI), extracted from the double rib cou-ture sign (DRCS) on lateral spinal radiographs to evaluate rib hump deformity in IS patients has been earlier introduced (Grivas at al 2000). Although various papers using the RI have been published, no study of its reproducibil-ity was reported. To estimate the variations of the RI in a(More)

We report a case of cervical epidural abscess from Enterococcus faecalis, which caused an insidious onset of tetraparesis. This 53-year-old female with a history of diabetes mellitus and chronic renal failure under hemodialysis presented with pain and progressive weakness of upper and lower extremities without fever. Although a recent MRI she did at the(More)
