The peculiar radiological and pathological findings of four pediatric cases admitted to the University Hospital of Padua between 1990 and 2007 are described. In all cases, the contrast-enhanced head and spine magnetic resonance images revealed thickened and abnormally enhancing subarachnoid spaces particularly at the level of basal cisterns and(More)
OBJECTIVES The principle underlying this project is that, despite nervous reorganization following upper limb amputation, original pathways and CNS relays partially maintain their function and can be exploited for interfacing prostheses. Aim of this study is to evaluate a novel peripheral intraneural multielectrode for multi-movement prosthesis control and(More)
Cervical degenerative pathology produces pain and disability, and if conservative treatment fails, surgery is indicated. The aim of this study was to determined whether anterior decompression and interbody fusion according to Cloward is effective for treating segmental cervical degenerative pathology and whether the results are durable after a(More)
Chordoid meningioma is a rare meningothelial tumor characterized by chordoma-like histological features with lymphoplasmacellular infiltration. This tumor is often seen in children, but not in adults, with a systemic inflammatory syndrome (iron-resistant microcytic anemia and/or dysgammaglobulinemia) and very rarely with a persistent moderate hyperthermia.(More)
Idiopathic spinal cord herniation (ISCH) is a rare, although increasingly recognized, cause of myelopathy. It is the result of an anterior dural defect in the thoracic spine through which the spinal cord herniates. Surgical restoration of the herniated cord to its normal position is usually followed by significant improvement in patients' clinical status.(More)
The aim of this study is to determine if radical microsurgical removal of cervical intramedullary spinal cord tumors (CIMSCT) is achievable without causing respiratory, motor and sphincter deficits. Sixteen consecutive patients, who underwent surgical removal of a cervical intramedullary spinal cord tumor between 1988 and 1997, are presented. Surgical(More)
BACKGROUND Odontoid fractures are the most common odontoid injury and often cause atlantoaxial instability. Reports on postoperative status of patients who underwent surgery for such injuries are limited to small case series, and it is unclear whether any one technique produces better outcomes than another. QUESTIONS/PURPOSES We assessed the quality of(More)
STUDY DESIGN Retrospective case review of children with eosinophilic granuloma of the cervical spine. OBJECTIVE To present the clinical features, radiographic findings, management, and results of 7 pediatric patients with eosinophilic granuloma of the cervical spine. SUMMARY OF BACKGROUND DATA Management of the eosinophilic granuloma of the pediatric(More)
Hypoxia commonly occurs in solid tumors of the central nervous system (CNS) and often interferes with therapies designed to stop their growth. We found that pediatric high-grade glioma (HGG)-derived precursors showed greater expansion under lower oxygen tension, typical of solid tumors, than normal CNS precursors. Hypoxia inhibited p53 activation and(More)
