Protective effect of the V1a receptor antagonist SR49059 on brain edema formation following middle cerebral artery occlusion in the rat
There exists no pharmacological treatment for fulminating brain edema. Since evidence indicates that brain aquaporin-4 (AQP4) water channels are modulated by vasopressin V1a receptors, we examined the edema-re...

Chapter and Conference Paper
Bolus tracer delivery measured by MRI confirms edema without blood-brain barrier permeability in diffuse traumatic brain injury
Previous studies have shown that edema formation after diffuse traumatic brain injury (TBI) with secondary insult is cytotoxic and not vasogenic. This assumption is based on observations of reduced apparent di...

Modulation of AQP4 expression by the protein kinase C activator, phorbol myristate acetate, decreases ischemia-induced brain edema
The protein kinase C activator, phorbol 12-myristate 13-acetate (PMA), is known to interact with aquaporin-4 (AQP4), a waterselective transporting protein abundant in astrocytes and ependymal cells, that has b...

Traumatic brain edema in diffuse and focal injury: cellular or vasogenic?
The objective of this study was to confirm the nature of the edema, cellular or vasogenic, in traumatic brain injury in head-injured patients using magnetic resonance imaging techniques. Diffusion-weighted ima...

Brain tissue water content in patients with idiopathic normal pressure hydrocephalus
Relatively little is known regarding the water content of brain tissue in idiopathic normal-pressure hydrocephalus (NPH) patients. The objective of our study was to determine absolute water content non-invasiv...

Chapter and Conference Paper
Effect of dimethyl sulfoxide on blood-brain barrier integrity following middle cerebral artery occlusion in the rat
Dimethyl sulfoxide (DMSO) is widely used as a solvent for other drugs, i.e., for the protein kinase C activator phorbol 12-myristate 13-acetate (PMA) and the V1a receptor-antagonist SR49059, to reduce brain ed...

Contribution of raised ICP and hypotension to CPP reduction in severe brain injury: correlation to outcome
The aim of this study was to determine to what degree hypotension and ICP contribute to the reduction of cerebral perfusion pressure (CPP), particularly in light of the shift in emphasis to CPP management by t...

Mitochondrial injury measured by proton magnetic resonance spectroscopy in severe head trauma patients
The aim of this study was to evaluate the extent of mitochondrial injury by assessing N-Acetyl-Aspartate by MR spectroscopy in head injured patients and relating the extent of mitochondrial injury to outcome. ...

Guidelines for management of idiopathic normal pressure hydrocephalus: progress to date
The aim of this project was to develop evidenced based guidelines for the diagnosis and management of idiopathic normal pressure hydrocephalus (iNPH). An advisory panel consisting of the authors assisted by in...

Chapter and Conference Paper
Mortality from traumatic brain injury
It is the general sense that mortality has been decreasing in recent years compared to earlier studies described by the NIH traumatic coma data bank. We studied mortality during the period of 1984 to 1996 to d...

The importance of translational research in brain injury
Progress in the understanding of the pathophysiologic process and management of brain injury provides a unique challenge to the young investigator. Currently, there are teams both in the laboratory and clinica...

Chapter and Conference Paper
Three-year outcome of shunted idiopathic NPH patients
The incidence of idiopathic normal pressure hydrocephalus (iNPH) has increased as a result of improved longevity. This report describes the 3-year outcome of shunted iNPH patients compared to three-month outco...

Clinical trials in traumatic brain injury: current problems and future solutions
Over the past decade many neuroprotective agents have been developed with the hope of being able to improve outcome in patients with traumatic brain injury. Unfortunately, none of the phase III trials performe...

Treatment of raised intracranial pressure following traumatic brain injury
Appropriate treatment of raised intracranial pressure (ICP) after traumatic brain injury (TBI) remains a controversial topic in ne-urotraumatology. Several techniques are employed clinically, which include vas...
