BACKGROUND In order to characterize the intracranial pressure-volume reserve capacity, the correlation coefficient (R) between the ICP wave amplitude (A) and the mean ICP level (P), the RAP index, has been used to improve the diagnostic value of ICP monitoring. Baseline pressure errors (BPEs), caused by spontaneous shifts or drifts in baseline pressure, cause erroneous readings of mean ICP. Con...

Progress in medical knowledge can be represented by an ascending spiral in which every loop stands over previous data, adds new findings that deepen our understanding of a disease, and helps to design further research and therapeutic strategies. New loops are frequently inspired by novel approaches to accepted hypotheses and usually supported by the use of more advanced technologies, as seems t...

The technique of coupling liquid chromatography to inductively plasma mass spectrometry (ICP-MS) is reviewed. A brief introduction to the ICP-MS instrument is given as well as methods to couple the two analytical instruments together. The various types of LC that have been used with ICP-MS detection are discussed and advantages over traditional methods of detection are highlighted, such as the ...

This paper attempts to predict Intracranial Pressure (ICP) based on features extracted from non-invasively collected patient data. These features include midline shift measurement and textural features extracted from Computed axial Tomography (CT) images. A statistical analysis is performed to examine the relationship between ICP and midline shift. Machine learning is also applied to estimate I...

The increasing use of shorter-acting hypnotic agents to control intracranial pressure (ICP) following severe head injury has prompted a prospective double-blind controlled trial comparing the efficacy of etomidate and Althesin, given by i.v. infusion. Over the dose ranges used, the two drugs appeared equipotent in decreasing ICP whilst preserving cerebral perfusion pressure. However, in two pat...

The first paper describing axial ICP was published in the mid 1970's (1). However, many years passed before the first commercial ICP emerged in 1993, followed by another ICP about a year later. The latter became an instant success. The race had started for lower detection limits with claims of 10 times better detection limits for most elements using an axial ICP. But as the atomic spectroscopy ...

' X Abstract We investigated an intracranial pressure (ICP) estimation method based on aqueductal cerebrospinal fluid (CSF) flow rate measurements from cine phase-contrast MR images. A fluid dynamics model is provided that relates CSF flow rate change to the elastance index, which is a parameter proportional to the ICP. Experimental results from 8 patients with clinical diagnosis of increased I...

Intrahepatic cholestasis of pregnancy (ICP) is associated to unpredictable fetal risks. The mechanisms underlying poor perinatal outcomes are unknown. Intracranial fetal hemorrhage is a possible complication of ICP. A young patient presented with mild ICP and severe transaminases elevation, at 32 weeks of pregnancy. Ultrasound revealed fetal ventriculomegalia probably secondary to intracranial ...
