The utility of routine intraoperative CSF during ventricular shunt insertion: a 10-year retrospective cohort study.

Objective: Ventricular shunt insertion is a common procedure in pediatric neurosurgical practice. In many areas of medicine there is a push toward rationalization of healthcare resources and a reduction in low-value tests or procedures. The intraoperative sampling of CSF at the time of shunt insertion is one traditional aspect of care that has not been rigorously evaluated.

Fourth ventricular roof angle does not predict surgical outcome in paediatric patients with Chiari I malformation.

Purpose: Pre-operative fourth ventricle roof angle (FVRA) has recently been highlighted as a novel radiographic predictor of clinical severity in Chiari type-I malformation (CM-I) as reported by Seaman et al. (J Neurosurg Pediatr 25:1-8, 2021). This has led to suggestions that FVRA could be included in algorithms to determine indications for surgery.

Synchronous intracranial arteriovenous malformation and papillary glioneuronal tumour: hypothesis or reality?

Brain arteriovenous malformations (AVM) rarely occur with spatial and/or temporal co-localisation to intracranial neoplasms. Most prior reports describe this association with high-grade gliomas; however, reports of a co-occurrence with low grade gliomas are very rare. It is unclear whether such cases represent a true co-occurrence of separate pathologies or simply an unusually vascular phenotype of the neoplasm.

Ten-year statewide cross-sectional review of pediatric sinogenic intracranial abscess and empyema in Queensland, Australia: microbial profile before and after COVID-19.

Objective: Sinogenic intracranial infections in children, such as subdural empyema or intracranial abscess, are a rare disease process with significant associated morbidity. Recent literature has suggested that there may have been an increase in frequency of these infections following the COVID-19 pandemic, but the literature has been conflicting, perhaps related to the heterogenous management of COVID-19 lockdowns in various states and differences in data capture between methods. The collection of statewide Australian data overcomes these limitations by capturing a comprehensive sample though the public healthcare system of patients who were subject to a homogeneous statewide approach to public health policy during the COVID-19 pandemic (population 5.
