Objectives: Intracranial devices may be used to treat or guide treatment of increased intracranial pressure in patients with pneumococcal meningitis. European guidelines do not recommend the routine use of intracranial devices in management of pneumococcal meningitis. However, in some countries, intracranial devices are used routinely, but the effect remains unknown. We aimed to examine whether mortality and sequelae were lower in patients with pneumococcal meningitis admitted to hospitals in regions in which intracranial devices were routinely used compared to regions not utilizing intracranial devices routinely in pneumococcal meningitis management.
Methods: In a registry-based, nationwide, population-based cohort study we examined patients with pneumococcal meningitis (Denmark, 2004-2021). Patients were categorized according to whether the individual was admitted to hospitals in regions where intracranial devices were routinely (exposed patients, n=305 of whom 66 (22%) had an intracranial device) or not routinely used (non-exposed patients, n=333 of whom 4 (1%) had an intracranial devices). We used Cox-regression to calculate adjusted mortality rate ratios (aMRR) and hazard ratios of sequelae for the short-term and long-term periods (<6 or ≥6 months after study inclusion).
Results: The short-term cumulative incidence of death was 22% among exposed patients and 22% among non-exposed patients. We found no association between mortality and routine use of intracranial devices in the region in which patients with pneumococcal meningitis were admitted (short-term aMRR (95% confidence interval [95%CI]): 0.9 [0.6-1.3], long-term aMRR [95%CI]: 1.0 [0.7-1.6]). Furthermore, our study did not demonstrate lower risks of diagnosis of epilepsy, hearing loss, diagnoses suggestive of brain damage, disability pension, or shorter length of stay in exposed compared with non-exposed patients with pneumococcal meningitis.
Conclusions: The routine use of intracranial devices is not associated with lower mortality or morbidity among patients with pneumococcal meningitis.

Minimally invasive interventions for intracranial pathologies using tubular retractors in the pediatric population: Safety, efficacy, technical aspects and outcomes.

Background: Minimally invasive surgeries for intracranial pathologies are gaining popularity, recognizing the intrinsic benefits, mostly related to recovery time, while minimizing injury to healthy parenchyma and adjacent functional areas, especially during the resection of deep and centrally located lesions. These procedures require technical familiarity and cultivated surgical experience, coupled with dedicated instruments, appropriate planning, and a stringent patient selection.
Objective: To describe our novel experience with minimally invasive trans-sulcal parafascicular surgery (MIPS) in a single-center pediatric population, emphasizing the interdependencies between surgical experience, best practices, preparation, and positive surgical outcomes.

Identifying epileptogenic zones non-invasively is challenging due to signal interference by the scalp and skull, necessitating invasive methods like subdural recordings and stereoelectroencephalography. Recent microcatheter advancements suggest that a microcatheter-compatible endovascular EEG (eEEG) device could overcome these barriers. We developed a thin, flexible eEEG electrode, the EP-01, for use with current microcatheters.

Purpose: It is unclear how flow diverters (FD) and vessels interact in the treatment of intracranial aneurysms. In this study, we examine the local changes in artery and device morphology caused by their mutual interaction.
Methods: Pre-treatment 3DRA and post-treatment XperCT or DynaCT images were collected retrospectively from 25 patients.

Endoscopy's ability to provide close observation, deep magnification, and multi-angle views has proven to be an effective tool for minimally invasive craniotomy in neurosurgery. However, no large case series have been published on the use of fully endoscopic-assisted minimally invasive keyhole craniotomy for clipping intracranial aneurysms (IAs). To evaluate the value of fully endoscopic-assisted minimally invasive keyhole craniotomy in the treatment of anterior circulation aneurysms.

The introduction of cerebrospinal fluid (CSF) drainage shunts has made treatment of hydrocephalus possible. However, failure rate is still high. Choice of shunt components could significantly reduce the need for revision, particularly using antisiphon devices and adjustable valves, at least in older patients.
