Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma.  Case Presentation: We...

BACKGROUND For patients suffering from primary brain injury, monitoring intracranial pressure alone is not enough to reflect the dynamic intracranial condition. In our previous study, a segment of the pressure-volume curve can be expressed by the parabolic regression model with single indicator "a". The aim of this study is to evaluate if the indicator "a" can reflect intracranial conditions. ...

We report our observations on MR imaging quality and functionality of a recently introduced intracranial pressure monitoring device. The device was tested at two different field strengths in a pig brain specimen to investigate MR imaging artifacts, probe function during and after MR data acquisition, and device-related temperature changes in the brain tissue. Image reading was not impaired, and...

To ensure safe and stable drilling operation, bottom hole pressure (BHP) should be kept within some region. However measurement of the BHP is sometimes not available or reliable, especially when the circulation is low, e.g., during pipe connection procedures. This paper presents the application of a moving horizon estimation (MHE) method for online estimation of the BHP during petroleum drillin...

objective(s): brain edema is one of the most serious causes of death within the first few days after trauma brain injury (tbi). in this study we have investigated the role of shilajit on brain edema, blood-brain barrier (bbb) permeability, intracranial pressure (icp) and neurologic outcomes following brain trauma.   materials and methods: diffuse traumatic brain trauma was induced in rats by dr...

Secondary insults can adversely influence outcome following severe traumatic brain injury. Monitoring of cerebral extracellular chemistry with microdialysis has the potential for early detection of metabolic derangements associated with such events. The objective of this study was to determine the relationship between the fundamental biochemical markers and neurological outcome in a large cohor...

PURPOSE OF REVIEW The review touches upon the current physiopathological concepts relating to the field of intracranial pressure (ICP) monitoring and offers an up-to-date overview of the ICP monitoring technologies and of the signal-analysis techniques relevant to clinical practice. RECENT FINDINGS Improved ICP probes, antibiotic-impregnated ventricular catheters and multimodality, computeriz...

OBJECTIVE The main concepts involved in the therapeutic management of intracranial hypertension are revisited, including pathophysiology, monitoring, the traditional approach, and also the presentation of recently proposed therapies. SOURCE OF DATA The main medical literature data bases (especially Medline and Lilacs) were searched for articles published in the last 10 years, and traditional ...

background: in previous studies, the neuroprotective effect of 17&beta-estradiol; in diffuse traumatic brain injury has been shown. this study used ici 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17&beta-estradiol; in traumatic brain injury is mediated by the estrogen receptors. methods: the ovariectomized rats were divided in...
