The diagnostic accuracy of magnetic resonance (MRI) signs of intracranial hypertension (ICH) in children remains unclear. This study aims to assess how brain MRI signs of ICH correlate with cerebrospinal fluid opening pressure (CSFOP). A retrospective case-control study was conducted with 77 children aged 1 to 18 years, who underwent brain MRI and lumbar puncture with CSFOP measurement. A blinded radiologist evaluated key ICH signs, including distension of the perioptic subarachnoid space, optic nerve (ON) tortuosity, posterior scleral flattening, intraocular protrusion, and enhancement of the prelaminar ON, among others. Odds ratios, likelihood ratios, predictive values, sensitivity, specificity, and the area under the ROC curve (AUROC), were calculated in relation to CSFOP, adjusted for age and sex. The ICH group included 38 patients (49.3%) and the control group 39 (50.7%). The presence of four or more MRI signs of ICH provided the best diagnostic performance (specificity 92%, sensitivity 40%, AUROC 0.759) for identifying elevated CSFOP, particularly with intraocular protrusion of the prelaminar ON (p = 0.006, median CSFOP 49.6 cm H 2 O, p < .001) and papilledema (p = 0.042)., Conclusion: The presence of four or more MRI signs is associated with elevated CSFOP in children with non-structural ICH., What Is Known: • The diagnostic accuracy of magnetic resonance imaging (MRI) signs of intracranial hypertension (ICH) in children remains unclear. • In children, there is no consensus about the most appropriate diagnostic criteria or robust evidence regarding the diagnostic performance of imaging signs for ICH., What Is New: • The presence of four or more MRI signs is associated with elevated cerebrospinal fluid opening pressure (CSFOP) in children with non-structural ICH. • Intraocular protrusion of the prelaminar ON, and papilledema are particularly relevant signs for identifying elevated CSFOP., Competing Interests: Declarations.

Cerebrospinal fluid opening pressure values are associated with various neurologic diseases; however, numerous factors can modify this measurement. This study aims to describe factors related to modifications in opening pressure measurements in pediatric patients. Methods: A retrospective analysis of lumbar punctures in pediatric patients conducted by the neuropediatrics group with institutional standardization. Bivariate and linear regression analyses were performed to determine the association between opening pressure and variables included in the study. Results: 544 events, median age 107 months, median opening pressure 19.7 cm H 2 O. Bivariate analysis found no association with medication use; anesthetics that increased opening pressure were remifentanil ( P = .02) and propofol ( P = .05), along with a positive linear correlation between opening pressure and age ( P  < .0001). Multiple linear regression analysis revealed that age, BMI, male gender, and remifentanil use were associated with an increase in opening pressure, whereas corticosteroid withdrawal was associated with a reduction in opening pressure. There is an interaction between age and headache, with an association with increased opening pressure up to around 140 months. Conclusion: This study identifies factors associated with changes in opening pressure, crucial for estimating normal opening pressure values in children. Headaches, anesthetic use, and corticosteroid withdrawal are confirmed as significant factors., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article. more...

Introduction: The ratio of cerebrospinal fluid (CSF) glucose and blood glucose is of major relevance, conducting to the diagnosis of hypoglycorrhachia, which is a sign of neuroinfection, as well as a number of neurological diseases of genetic or neoplastic etiology. Glucose in capillary sample (glucometry) is a low cost, readily available technique, as compared to venous glucose. This study aims to compare glucometry to venous glucose in the diagnosis of hypoglycorrhachia in pediatric population., Methods: Prospective cross-sectional study based on data obtained from lumbar punctures in the period from February 2017 to January 2019 in a specialized pediatric institution in Colombia., Results: 97 patients were analyzed, aged 1 month to 17 years old, mean 7.67 years, 52 (53.61%) were female. 26 (26.8%) were diagnosed with hypoglycorrhachia. Pearson correlation coefficient for absolute venous and capillary glucose was 0.54, and 0.55 for the ratios of CSF glucose/venous glucose and CSF glucose/glucometry, which support a linear correlation between the variables in both, absolute values and ratios. Intraclass correlation coefficient was calculated for both, the venous glucose and glucometry ratios, which was 0.52, revealing a moderate agreement among the tests. Sensitivity and specificity of CSF glucose/glucometry, as compared to gold standard are 73.1% and 60.6% respectively; whereas predictive positive value (PPV) and negative predictive value (NPV), were 40.4% and 86.0%., Conclusion: Glucometry cannot replace the glucose in venous sample in the diagnosis of hypoglycorrhachia in children., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 The Japanese Society of Child Neurology.
