Intracranial hypertension

 

Correlación entre variables clínicas sugestivas de hipertensión intracraneal y alteraciones en la neuroimagen en trauma craneoencefálico. Correlation between clinical variables suggestive of intracranial hypertension and alterations in neuroimaging in traumatic brain injury

Methods: Retrospective observational cohort study where patients admitted for TBI to the ICU area of the HLV were included. 

Results: We included a total of 297 subjects. The most common neuroimaging lesion was multiple lesions (35.4%). We found that there is a significant correlation between the presence of lesion in neuroimaging and the presence of fixed pupils at admission (p = <0.001), score ≤ 8 on the Glasgow scale (p = <0.001) and need for orotracheal intubation (p = <0.001). Similarly, the same 3 variables were significant when related to the score ≥ III on the Marshall scale. In the logistic regression model, pupil fixation was the only one that was shown to increase the risk of a score ≥ III on the Marshall scale (OR: 3.50, 95% CI 1.53-7.99). 

Conclusion: The clinical variables: pupil fixation, need for endotracheal intubation and Glasgow ≤ 8 are related to the development and severity of lesion on neuroimaging in patients with TBI.

Las Aquaporinas y el Sistema Nervioso Central. Aquaporins and Central Nervous System.

The discovery of aquaporins, which constitute a family of integral membrane proteins, has meant a change with respect to the understanding of water transport in biological membranes. The most important is aquaporin 4 (AQP4) which we will focus on below, although there are two other aquaporins, 1 and 9. These aquaporins are of great importance in the physiology of cell volume control and osmotic control mechanisms of the cells. Also in the control of the flow of glycerol and other solutes. In addition, alterations in its functioning have been related to various diseases of the central nervous system such as neuromyelitis optics, cerebral edema, idiopathic intracranial hypertension or chronic hydrocephalus of the adult among others. A review is made on this topic.
