Intracranial pressure (ICP) measurements are essential in evaluation and treatment of neurological disorders such as subarachnoid and intracerebral hemorrhage, ischemic stroke, hydrocephalus, meningitis/encephalitis, and traumatic brain injury (TBI). The techniques of ICP monitoring have evolved from invasive to non-invasive-with both limitations and advantages. Some limitations of the invasive...

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...

In order to describe variation in AP and ICP during OSA, six patients with severe OSA were examined, with determination of ICP, AP, CVP, respiration, tcPO2, tcPCO2, and nocturnal sleep polygraphy. During apnea, elevations of AP and ICP were observed, related to the apneic episodes. The elevations in pressure were only observed in relation to apneic episodes. While awake, none of the patients sh...

BACKGROUND The correlation between intracranial pressure (ICP) and intraocular pressure (IOP) is still controversial in literature and hence whether IOP can be used as a non-invasive surrogate of ICP remains unknown. The aim of the current study was to further clarify the potential correlation between ICP and IOP. METHODS The IOP measured with Goldmann applanation tonometer was carried out on...

BACKGROUND AND AIMS The aim of this study was to investigate the genetic aetiology of intrahepatic cholestasis of pregnancy (ICP) and the impact of known cholestasis genes (BSEP, FIC1, and MDR3) on the development of this disease. PATIENTS AND METHODS Sixty nine Finnish ICP patients were prospectively interviewed for a family history of ICP, and clinical features were compared in patients wit...

We describe the structure and functionality of the Internet Cache Protocol (ICP) and its implementation in the Squid Web Caching software. ICP is a lightweight message format used for communication among Web caches. Caches exchange ICP queries and replies to gather information to use in selecting the most appropriate location from which to retrieve an object. We present background on the histor...

Intracranial pressure (ICP) monitoring was carried out in 100 patients with severe acute brain trauma, primarily by means of a subarachnoid catheter. Statistical associations were evaluated between maximum ICP values and: 1) Glasgow Coma Scale (GCS) scores; 2) findings on computed tomography (CT) scans of the head; and 3) mortality. A significant association was found between low GCS scores (3 ...

BACKGROUND Intracranial pressure (ICP) monitoring is a cornerstone of care for severe traumatic brain injury (TBI). Management of ICP can help ensure adequate cerebral blood flow and oxygenation. However, studies indicate that brain hypoxia may occur despite normal ICP and the relationship between ICP and brain oxygenation is poorly defined. This is particularly important for children in whom l...

A recent study has reported an excellent correlation between intraocular pressure (IOP) and intracranial pressure (ICP), suggesting that measurement of IOP may serve as a noninvasive means to determine ICP. To reexamine the relation between IOP and ICP, we reviewed the medical records of all patients who underwent lumbar puncture between 1991 and 2007 in the neuro-ophthalmology clinic at the Un...

The Iterative Closest Point (ICP) algorithm can accurately register and match 3D rigid surfaces. However, when it comes to non-rigid or semi-rigid surfaces such as the human face, the performance of ICP drops significantly. In this paper, we extend the ICP algorithm and propose a Semi-Rigid ICP algorithm which can match and register semi-rigid surfaces. We compare the performance of SRICP and I...
