Meningiomas of the spine are the most common benign intradural extramedullary lesions and account for 25%-46% of all spinal cord tumors in adults. The goal of treatment is complete surgical resection while preserving spinal stability. Usually, these lesions occur in the thoracic region and in middle-aged women. Clinical presentation is usually nonspecific(More)
During resting tidal breathing the shape of the expiratory airflow waveform differs with age and respiratory disease. While most studies quantifying these changes report time or volume specific metrics, few have concentrated on waveform shape or area parameters. The aim of this study was to derive and compare the centroid co-ordinates (the geometric centre)(More)
Spinal subarachnoid hematoma (SSH) is a rare condition, more commonly occurring after lumbar puncture for diagnostic or anesthesiological procedures. It has also been observed after traumatic events, in patients under anticoagulation therapy or in case of arteriovenous malformation rupture. In a very small number of cases no causative agent can be(More)
Paravertebral titanium rod migration represents an unusual and potentially fatal complication of vertebral stabilization surgical procedures. This condition, which requires a prompt and rapid diagnosis, is often mistaken for other more common diseases, or scotomized. We present a case of a 69 years old female affected by a non-Hodgkin lymphoma with evidence(More)
STUDY DESIGN Retrospective study. PURPOSE The aim of our study was to analyze the safety and effectiveness of posterior pedicle screw fixation for treatment of pyogenic spondylodiscitis (PSD) without formal debridement of the infected tissue. OVERVIEW OF LITERATURE Posterior titanium screw fixation without formal debridement of the infected tissue and(More)
BACKGROUND Traumatic thoracolumbar spinal fractures represent approximately 65% of all traumatic spinal fractures and are frequently associated to permanent disability with significant social and economic impact. These injuries create severe physical limitations depending on neurological status, level of fracture, severity of injury, patient age and(More)
OBJECTIVE AND BACKGROUND The objective of this study is to evaluate how the neurological outcome in patients operated for cervical spinal cord injury (SCI) is influenced by surgical timing, admission American Spinal Injury Association (ASIA) grading system, and age. MATERIALS AND METHODS From January 2004 to December 2011, we operated 110 patients with(More)
BACKGROUND Different surgical approaches have been developed for dealing with third ventricle lesions, all aimed at obtaining a safe removal minimizing brain manipulation. The supraorbital subfrontal trans-lamina terminalis route, commonly employed only for the anterior third ventricle, could represent, in selected cases with endoscopic assistance, an(More)
Background and Study Aims Surgical treatment for acute subdural hematomas (ASDHs) in elderly patients is still considered unsatisfactory. Series focusing on the use of conventional craniotomy or decompressive craniectomy in such patients report discouraging results. Glasgow Coma Scale (GCS) score at admission seems to be crucial in the decision-making(More)
BACKGROUND Treatment of multiple intracranial aneurysms is particularly demanding and even more so in a developing country where access to specialized centers may be prevented by different factors. METHODS Single-stage surgical treatment of 7 cerebral aneurysms was performed in a 58-year-old woman from the northern Peruvian Andes. RESULTS All 7(More)
