Glutamate-mediated excitotoxicity involving N-methyl-d-aspartate (NMDA) receptors has been recognized as a final common outcome in pathological conditions involving death of retinal ganglion cells (RGCs). Overstimulation of NMDA receptors results in influx of calcium (Ca) and sodium (Na) ions and efflux of potassium (K). NMDA receptors are blocked by magnesium (Mg). Such changes due to NMDA overstimulation are also associated with not only the altered levels of minerals but also that of trace elements and redox status...

Ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and traumatic brain injury-all have in common early brain injury due to brain tissue destruction, reduced cerebral blood flow and oxygen delivery, and overall substantial morbidity and mortality. The pathophysiology of brain tissue damage likely includes common cellular mechanisms. Neuroprotection has seldom, if ever, been shown to reduce early brain injury. Secondary brain injury develops after these conditions due to macroscopic events such as increased intracranial pressure and reduced cerebral blood flow, as well as cellular processes including vascular damage, inflammation, and apoptotic/necrotic cell death...

Exposure to blast overpressure (BOP) activates a cascade of pathological processes including changes in intracranial pressure (ICP) and blood-brain barrier (BBB) permeability resulting in traumatic brain injury (TBI). In this study the effect of single and multiple exposures at two intensities of BOP on changes in ICP and BBB permeability in Sprague-Dawley rats was evaluated. Animals were exposed to a single or three repetitive (separated by 0.5 h) BOPs at 72 kPa or 110 kPa. ICP was monitored continuously via telemetry for 6 days after exposure to BOP...

The pseudotumor cerebri syndrome (PTCS), also known as idiopathic intracranial hypertension (IIH), is characterized by signs and symptoms of increased intracranial pressure such as headache and cranial nerve palsies, in the absence of any space-occupying mass. This condition commonly affects overweight women of childbearing age, even if it is also frequent in men and children. Children with PTCS may present with atypical signs and symptoms, with a different prognosis compared to adults. However, the treatment is the same for both children and adults, even if there are no strict treatment guidelines in regards...

Megan L Lawlor, Agatha S Critchfield
Intrahepatic cholestasis of pregnancy (ICP) is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L...

REVIEW
Marc J Dinkin, Athos Patsalides
Idiopathic intracranial hypertension causes headache, papilledema and visual field loss, typically in obese women of childbearing age. Its anatomical underpinnings remain unclear, but a stenosis at the junction of the transverse and sigmoid sinuses has been recognized in the majority of patients through venography. The stenosis may result from intrinsic dural sinus anatomy or extrinsic compression by increased intracranial pressure, but in either case, its stenting has been shown to lead to an improvement in symptoms of intracranial hypertension and papilledema in multiple retrospective, non-controlled studies...

This study focused on the generation of aerosols of titanium dioxide (TiO2) nanoparticles (NPs) and their disposition kinetics in rats. Male Sprague-Dawley rats were exposed by inhalation to 15mg/m(3) of anatase TiO2 NPs (∼20nm) during 6h. Rats were sacrificed at different time points over 14days following the onset of inhalation. Ti levels were quantified by ICP-MS in blood, tissues, and excreta. Oxidative damages were also monitored (MDA). Highest tissue levels of Ti were found in lungs; peak values were reached only at 48h followed by a progressive decrease over 14 days, suggesting a persistence of NPs at the site-of-entry...

Central neurocytoma (CN) is a rare, benign brain tumor often located in the lateral ventricles. CN may cause obstructive hydrocephalus and manifest as signs of increased intracranial pressure. The goal of treatment for CN is a gross total resection (GTR), which often yields excellent prognosis with a very high rate of tumor control and survival. Adjuvant radiosurgery and radiotherapy may be considered to improve tumor control when GTR cannot be achieved. Chemotherapy is also not considered a primary treatment, but has been used as a salvage therapy...
