PURPOSE Because a lowered intracranial pressure (ICP) is a possible mechanism of optic neuropathy, we wished to study the CSF dynamics in the optic nerve chamber by recording possible changes in the optic nerve subarachnoid space pressure (ONSP) and the impact on it when acutely lowering ICP. METHODS In eight normal dogs pressure probes were implanted in the left brain ventricle, lumbar ciste...
BACKGROUND In brain-injured patients intracranial pressure (ICP) is monitored invasively by a ventricular or intraparenchymal transducer. The procedure requires specific expertise and exposes the patient to complications such as malposition, hemorrhage or infection. As inner-ear fluid compartments are connected to the cerebrospinal fluid space, ICP changes elicit subtle changes in the physiolog...
OBJECTIVES To determine the alterations in intracranial pressure (ICP) during U. S. Air Force Critical Care Air Transport Team transport of critically injured warriors with ICP monitoring by intraventricular catheter (IVC). METHODS Patients with an IVC following traumatic brain injury requiring aeromedical evacuation from Bagram to Landstuhl Regional Medical Center were studied A data logger ...
Increased intracranial pressure (ICP) is a serious complication of a variety of neurologic injuries and is a major challenge in intensive care units. The most common causes of increased ICP are: traumatic brain injury (TBI), stroke, neoplasms, hydrocephalus, hepatic encephalopathy, CNS venous return impairment, encephalitis, and abscesses. Prompt diagnosis and intensive monitoring and therapy o...
CFTR mutations enhance susceptibility for idiopathic chronic pancreatitis (ICP) and congenital bilateral absence of the vas deferens (CBAVD); however, it is unknown why CFTR heterozygotes are at increased disease risk. We recently showed that common CFTR variants are associated with aberrantly spliced transcripts. Here, we genotyped for common CFTR variants and tested for associations in two IC...
OBJECTIVE The LiquoGuard® system is a new ventricular-type monitoring device that facilitates intracranial pressure (ICP)-controlled or volume-controlled drainage of cerebrospinal fluid (CSF). The purpose of this study is to report the authors' experience with the LiquoGuard® ICP monitoring system, as well as the clinical safety, usefulness, and limitations of this device in the management of p...
BACKGROUND The objective of this study is to characterize the relationship between ICP and EEG METHODS: Simultaneous ICP and EEG data were obtained from burst-suppressed patients and segmented by EEG bursts. Segments were categorized as increasing/decreasing and peak/valley to investigate relationship between ICP changes and EEG burst duration. A generalized ICP response was obtained by averagi...

Leishmania mexicana cysteine peptidases (CPs) have been identified as important parasite virulence factors. More recently, a natural inhibitor of CPs (ICP) from L. mexicana has been characterized, and ICP mutants have been created. Infection of BALB/c mice with ICP null mutants or ICP reexpressing mutants resulted in nonhealing, progressively growing lesions albeit slightly attenuated compared ...
BACKGROUND Cerebral perfusion pressure management (CPPM) is an accepted modality of treatment of severe diffuse head injury (SDHI). However, CPPM has the potential to cause transcapillary exudation in the presence of a disrupted blood brain barrier and can lead to further increase of intracranial pressure (ICP) and worsening of compliance. AIMS This study attempts to evaluate the effect of bo...
