Previous reports have described concomitant presentation of papilledema and Chiari malformation type 1 (CM1). The pathophysiology of each and their relationship remain poorly understood. As such, different management approaches regarding treating the CM1 or the pseudotumor initially have been described, with varying degrees of success. We report the case of an 11 year old girl with 6 mm tonsill...

Background: Measurements of the optic nerve sheath diameter (ONSD) using bedside ultrasound (US) have been shown to correlate with clinical and radiologic signs and symptoms of increased intracranial pressure (ICP). Objectives: Previous literature has identified 5 mm as the ONSD measurement above which patients exhibit either clinical or radiologic signs of elevated ICP. The goals of this study...

Patients with isolated severe head injury with diffuse axonal injury and without any surgical lesion may be treated safely without cerebral resuscitation and intracranial pressure (ICP) monitoring. Seventy two patients were divided into three groups of patients receiving treatment based on ICP-CPP-targeted, or conservative methods either with or without ventilation support. The characteristics ...

The understanding of raised intracranial pressure (ICP) is increasing with the directed use telemetric ICP monitors. This case uniquely observed changes by monitoring in a patient idiopathic hypertension (IIH), who developed rapid sight-threatening disease. A lumbar drain was inserted, as temporising measure, and clamped prior to surgery. resulted rise ICP, which normalised after insertion vent...

A methodology based on coupling isocratic high-performance liquid chromatography (HPLC) and inductively coupled plasma mass spectrometry (ICP-MS) with optimized collision/reaction cell conditions has been developed for the simultaneous analysis of organic and inorganic selenium species in natural water samples. Selenium concentrations found in total and speciation analysis of a number of water ...

Reducing total sulfur in motor fuels has become a critical air pollution control goal worldwide. As countries mandate ever lower permissible levels of total sulfur in fuels, the environmental monitoring and fuel manufacturing industries have been forced to find more sensitive techniques for analysis. Gas chromatography coupled to inductively coupled plasma mass spectrometry (GC-ICP-MS) has the ...

The relationship between the intra-abdominal pressure (IAP) and intracranial (ICP) has been suspected for more than 100 years was subsequently confirmed by numerous studies in both animals humans which demonstrate link positive correlation IAP ICP. There are mounting concerns that pneumoperitoneum created during laparoscopic surgery to create space instrument placement allow safe tissue dissect...

BACKGROUND AND PURPOSE Predictors of clinical outcome in aneurysmal subarachnoid hemorrhage (SAH) vary in reliability. Measurement of cerebral venous hemodynamics by transcranial color-coded duplexsonography (TCCS) has become of increasing interest lately, and correlation with intracranial pressure (ICP) seems to be high. The aim of the presented study was to assess changes of cerebral venous h...

Nanomaterials are increasingly used in food production and packaging, and validated methods for detection of nanoparticles (NPs) in foodstuffs need to be developed both for regulatory purposes and product development. Asymmetric flow field-flow fractionation with inductively coupled plasma mass spectrometric detection (AF(4)-ICP-MS) was applied for quantitative analysis of silver nanoparticles ...

Mortality and adverse neurologic sequelae from HIV-associated cryptococcal meningitis (HIV-CM) remains high due to raised intracranial pressure (ICP) complications. Cerebrospinal fluid (CSF) high opening pressure occurs in more than 50% of HIV-CM patients. Repeated lumbar puncture with CSF drainage and external lumbar drainage might be required in the management of these patients. Usually, ther...
