STUDY DESIGN This is a case report of a 37-year-old woman who sought treatment for a large syringomyelic cavitation extending from C3 to the entire medulla, a tetraventricular hydrocephalus, and a cystic cavitation in the posterior cranial fossa communicating with the fourth ventricle (Blake's pouch cyst). The patient underwent a decompressive craniectomy,(More)
Thirty patients with 33 vascular injuries from blunt trauma to the brachiocephalic branches of the aortic arch are reported. To our knowledge, this is the largest series reported to date of blunt injuries to these vessels. Mechanisms of injury included deceleration, traction, and crush. Half of the injured vessels were the innominate artery, and a quarter(More)
OBJECTIVE To analyze the risk factors of worst outcome associated with moderate head injury. METHODS Data on patients with moderate head injury were collected prospectively in 11 Italian neurosurgical units over a period of 18 months. Patients older than 18 years with blunt head injury and at least one Glasgow Coma Scale (GCS) score between 9 and 13 were(More)
We report a 13-year-old boy who developed severe, refractory dystonia-dyskinesias as an abrupt worsening of a previously nonprogressive movement disorder. The movements became continuous, requiring artificial respiration and continuous sedation in the intensive-care unit. Various drugs and drug combinations failed to achieve control. The child was then(More)
Expression and release of nociceptin/orphanin FQ (N/OFQ) are elevated in the substantia nigra reticulata of 6-hydroxydopamine-hemilesioned rats, suggesting a pathogenic role for N/OFQ in Parkinson's disease. In this study, we investigated whether elevation of N/OFQ expression in 6-hydroxydopamine-hemilesioned rats selectively occurs in substantia nigra and(More)
OBJECTIVE To evaluate seizures as first clinical manifestation of brain arteriovenous malformations (AVMs), in relation to angioarchitectural features of these vascular anomalies. METHODS We performed a prospective observational study, collecting records of patients with AVMs consecutively admitted to the Neurological and Neurosurgery Units of Perugia(More)
After spinal cord injury, quadriplegic patients generally require tracheostomy for ventilatory support and airway clearance. Early tracheostomy has several advantages over translaryngeal intubation, but in patients who undergo anterior surgical fixation of the spine, it is often delayed until after recovery of the surgical wound. We report the case of a(More)
Pharmacokinetic (PK) interactions between protease inhibitors (PI(s)) and immunosuppressive agents (IS) are critical elements in the management of HIV-infected patients who undergo liver transplantation (LT(x)). The primary objective of this study was to evaluate the decreases in IS dosages necessary to maintain an appropriate therapeutic window (TW) after(More)
Congenital pseudarthrosis of the clavicle is a rare condition. Bilateral involvement is extremely rare: only seven cases have been reported in the literature. Although the anatomy of the thoracic outlet can be markedly altered by the hypermobility of the shoulder and although few cases with mild symptoms suggesting brachial plexus impairment have been(More)
