There is an urgent need for both the scientific development and clinical validation of novel therapies for acute spinal cord injury (SCI). The scientific development of novel therapies would be facilitated by a better understanding of the acute pathophysiology of human SCI. Clinical validation of such therapies would be facilitated by the availability of(More)
From 1974 to 1988, 15 adult patients (aged over 16 years) with cerebellar medulloblastomas were observed in our Neurosurgical Department. All were treated by total (8 patients) or subtotal (7 patients) resection of the tumor, followed by radiation therapy to the posterior cranial fossa, spine and whole brain. A 5-year survival was achieved in 7 patients(More)
OBJECT Ischemia is an important factor in the pathophysiology of secondary damage after traumatic spinal cord injury (SCI) and, in the setting of thoracoabdominal aortic aneurysm repair, can be the primary cause of paralysis. Lowering the intrathecal pressure (ITP) by draining CSF is routinely done in thoracoabdominal aortic aneurysm surgery but has not(More)
Since an objective noninvasive method for measuring inflammation in arthritis is lacking, radioimaging experiments were conducted with 111indium-chloride (111InCl3) in the collagen model. A computer imaging index, reflecting uptake in the feet and ankles, was significantly greater in 16 rats immunized with collagen than in 6 nonimmunized rats (mean +/- SEM(More)
Fifty patients with intracranial meningiomas, verified histologically, are retrospectively analyzed to correlate the peritumoral brain edema with the positivity of estrogen receptors and progesterone receptors. The extent of edema was quantified on CT scan and/or MR. Monoclonal antibodies were used to test the estrogen receptors and the dextran-coated(More)
BACKGROUND AND PURPOSE The Medical Physics Division of the Portuguese Physics Society (DFM_SPF) in collaboration with the IAEA, carried out a national auditing project in radiotherapy, between September 2011 and April 2012. The objective of this audit was to ensure the optimal usage of treatment planning systems. The national results are presented in this(More)
Eighty-three patients with intraplaque hemorrhage of the carotid arteries, explored by Duplex scanning, are reported; 36 among them were also studied by digital angiography and 28 were operated on. The echographic aspect suggesting the presence of an intraplaque hemorrhage is that of a hypo-anechogenic stria separating the intimal plaque from the(More)
