Special Issue Information

Dear Colleagues,

The daily practice of neurocritical care focuses on the monitoring and treatment of children and adults suffering from a wide range of neurological disorders. A variety of techniques are continuously being developed to further improve the diagnosis, prognosis, and treatment of patients with acute head and spinal injuries, subarachnoid and intracranial hemorrhages, cerebral vascular abnormalities, tumours, intracranial pressure issues, infectious diseases, patients in comatose states, etc. Timely diagnosis, efficient intervention, and accurate monitoring of the condition are crucial to patient outcome. In this Special Issue, we would like to invite all contributions that demonstrate an improvement in cerebrovascular health monitoring or in the treatment of major brain injuries or neurological disorders.

Topics include (but are not limited to) the following areas: cerebrovascular health monitoring using Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) neuroimaging techniques, multi-modality neuromonitoring, EEGs, brain tissue perfusion monitoring, intracranial pressure monitoring, cerebral oxygenation monitoring, biomarkers.

The article may be either original research or a review. There is no length restriction.

Dr. Daniel Milej
Guest Editor

Abstract
Post-hemorrhagic ventricular dilatation (PHVD) is characterized by a build-up of cerebral spinal fluid (CSF) in the ventricles, which increases intracranial pressure and compresses brain tissue. Clinical interventions (i.e., ventricular taps, VT) work to mitigate these complications through CSF drainage; however, the timing of [...] Read more.
Post-hemorrhagic ventricular dilatation (PHVD) is characterized by a build-up of cerebral spinal fluid (CSF) in the ventricles, which increases intracranial pressure and compresses brain tissue. Clinical interventions (i.e., ventricular taps, VT) work to mitigate these complications through CSF drainage; however, the timing of these procedures remains imprecise. This study presents Neonatal NeuroMonitor (NNeMo), a portable optical device that combines broadband near-infrared spectroscopy (B-NIRS) and diffuse correlation spectroscopy (DCS) to provide simultaneous assessments of cerebral blood flow (CBF), tissue saturation (StO2), and the oxidation state of cytochrome c oxidase (oxCCO). In this study, NNeMo was used to monitor cerebral hemodynamics and metabolism in PHVD patients selected for a VT. Across multiple VTs in four patients, no significant changes were found in any of the three parameters: CBF increased by 14.6 ± 37.6% (p = 0.09), StO2 by 1.9 ± 4.9% (p = 0.2), and oxCCO by 0.4 ± 0.6 µM (p = 0.09). However, removing outliers resulted in significant, but small, increases in CBF (6.0 ± 7.7%) and oxCCO (0.1 ± 0.1 µM). The results of this study demonstrate NNeMo’s ability to provide safe, non-invasive measurements of cerebral perfusion and metabolism for neuromonitoring applications in the neonatal intensive care unit.

There is a persistent debate on the optimal target temperature to use during cooling procedures in cardiac arrest survivors. A large randomized clinical trial (RCT) including more than 900 patients showed that targeted temperature management (TTM) at 33 °C had similar mortality and unfavorable neurological outcome (UO) rates as TTM at 36 °C in out-of-hospital cardiac arrest patients with any initial rhythm. Since then, several observational studies have been published on the effects of changes in target temperature (i.e., from 33 to 36 °C) on patients’ outcome. We performed a systematic literature search from 1 January 2014 to 4 December 2020 and identified ten retrospective studies (very low levels of certainty; high risk of bias), including 5509 patients, that evaluated TTM at 33 °C vs. TTM at 36 °C on the occurrence of UO (n = eight studies) and mortality (n = ten studies). TTM at 33 °C was associated with a lower risk of UO when studies assessing neurological outcome with the Cerebral Performance Categories were analyzed (OR 0.80 [95% CIs 0.72–0.98]; p = 0.03). No differences in mortality were observed within the two TTM strategies. These results suggest that an inappropriate translation of TTM protocols from large well-conducted randomized trials into clinical management may result in unexpected effects on patients’ outcome. As for all newly commercialized drugs, epidemiological studies and surveillance programs with an adequate follow-up on large databases are necessary to understand how RCTs are implemented into medical practice.

Occasionally, acute ischemic stroke can be difficult to differentiate from acute intracranial infection. We describe a patient who presented with sudden onset of right hemiparesis and fever. Magnetic resonance imaging (MRI) was consistent with an acute stroke, showing multiple lesions with restricted diffusion in the left middle cerebral artery territory. These lesions were not enhancing and were not associated with vasogenic edema. A diagnosis of acute stroke was made based on the clinical and radiographic data. Follow-up MRI obtained eleven days later showed interval development of ring enhancement and vasogenic edema surrounding the previously noted core of restricted diffusion. Based on these findings, the diagnosis was revised to cerebral abscesses and the patient was treated successfully with antibiotics. In retrospect, the largest diffusion-weighted lesion on baseline MRI demonstrated two characteristics that were atypical for stroke: it had an ovoid shape and a subtle T2 hypointense core. This case demonstrates that acute clinical and radiographic presentation of cerebral abscess and ischemic stroke can be strikingly similar. Follow-up imaging can be instrumental in arriving at an accurate diagnosis. Full article

Neisseria meningitidis-induced acute systemic meningococcal disease is an emergency and a fatal condition that has a high mortality rate. In patients with a fulminant infection, a maculopapular petechial eruption, purpura fulminans, or an ecchymotic lesion are worrisome signs reflecting disseminated intravascular coagulation (DIC) and hint at Waterhouse–Friderichsen syndrome (WFS). Here, we describe a rare case of a patient with a fulminant Neisseria meningitidis-induced acute systemic meningococcal disease presenting with high-grade fever without meningitis symptoms. Fatal septicemia with DIC and multiple organ failure was noted. WFS was chiefly suspected. We highlight the clinical features and pathogenesis of Neisseria meningitidis-induced meningococcemia and WFS. We propose that they should be kept in mind, especially in patients presenting with a petechial eruption and purpura fulminans. Full article
