Brain temperature, body core temperature, and intracranial pressure in acute cerebral damage.
To assess the frequency of hyperthermia in a population of acute neurosurgical patients; to assess the relation between brain temperature (ICT) and core temperature (Tc); to investigate the effect of changes in brain temperature on intracranial pressure (ICP). ⋯ Fever is extremely frequent during acute cerebral damage and ICT is significantly higher than Tc. Moreover, Tc may underestimate ICT during the phases when temperature has the most impact on the intracranial system because of the close association between increases in ICT and ICP.

Magnetic resonance imaging of the entorhinal cortex and hippocampus in mild cognitive impairment and Alzheimer's disease.
To explore volume changes of the entorhinal cortex (ERC) and hippocampus in mild cognitive impairment (MCI) and Alzheimer's disease (AD) compared with normal cognition (NC); to determine the powers of the ERC and the hippocampus for discrimination between these groups. ⋯ Volume reductions in the ERC and hippocampus may be early signs of AD pathology that can be measured using MRI.

Spinal cord magnetic resonance imaging demonstrates sensory neuronal involvement and clinical severity in neuronopathy associated with Sjögren's syndrome.
To determine spinal cord MRI findings in neuronopathy associated with Sjögren's syndrome and their correlation with severity of sensory impairment. ⋯ High intensity areas on T2* weighted MRI in the spinal dorsal columns reflect the degree of sensory neuronal involvement in neuronopathy associated with Sjögren's syndrome; this finding could also be a helpful marker for estimating severity of this neuronopathy.

Increase of interstitial glycerol reflects the degree of ischaemic brain damage: a PET and microdialysis study in a middle cerebral artery occlusion-reperfusion primate model.
To evaluate interstitial glycerol as a marker of ischaemia by studying the changes in glycerol in direct relation to changes in regional cerebral metabolic rate of oxygen (CMRO(2)), the lactate/pyruvate ratio (LP ratio), and glutamate. ⋯ A marked, sustained increase in interstitial glycerol is indicative of severe ischaemia in this stroke model. A transient, diminutive increase in interstitial glycerol may reflect a penumbra situation. Interstitial glycerol in combination with other biochemical markers such as the LP ratio and glutamate may be useful for clinical monitoring of the ischaemic brain, reflecting a sequence of secondary pathophysiological events.
