Current state of social media utilization in neurosurgery amongst European Association of Neurosurgical Societies (EANS) member countries.

BACKGROUND Social Media (SoMe) is becoming increasingly used in the medical community, and its use has been related with academic productivity. However, utilization of SoMe in the European neurosurgical community has not been assessed systematically. METHODS An online search was undertaken to discover SoMe accounts of (1) national and related neurosurgical societies listed on the EANS website, (2) neurosurgical journals present on EANS website, (3) neurosurgery centers within EANS member countries, as listed on their website. SoMe accounts of Facebook, Twitter, YouTube, and Instagram were searched for journals and societies, and Twitter, Instagram, and Facebook for neurosurgery departments. The number of likes/followers/subscribers was recorded. RESULTS Five (31%) neurosurgery journals had a SoMe presence. The highest number of followers, likes, and tweets was found for JNNP, and Journal of Neurological Surgery Part B had the most subscribers and video views. SoMe usage was identified for 11 national (28.2%) and 2 multi-national neurosurgical societies. From these, the French Society of Neurosurgery had the largest number of Facebook followers (> 2800) and Likes (> 2700), the Society of British Neurological Surgeons had the largest number of Twitter followers (> 2850), whereas EANS overall had the most followers on Twitter > 5100 and Facebook > 5450. A total of 87 SoMe neurosurgery center accounts were found on either Facebook, Instagram or Twitter, for 64 of 1000 centers (6.4%) in 22 of 40 different countries (55%). Of these 67% (n = 43/64) arose from 6 countries (England, Germany, Italy, Romania, Turkey, Ukraine). There were more Facebook accounts (n = 42) than Instagram accounts (n = 23) or Twitter accounts (n = 22). CONCLUSION SoMe use amongst neurosurgical societies and departments in Europe is very limited. From our perspective, explanations are lacking for the correlated numbers to the market shares of SoMe in the respective countries. Further research, including a survey, to follow up on this important topic should be undertaken among EANS members

What are the options for cardiac standstill during aneurysm surgery? A systematic review

To perform a systematic review of the techniques for transient circulatory arrest during intracerebral aneurysm surgery according to the PRISMA guidelines. Search of PubMed and Google Scholar using the following: ("heart arrest" OR "cardiac standstill"[All Fields]) AND ("intracranial aneurysm" OR "intracranial"[All Fields] AND "aneurysm"[All Fields]). A total of 41 original articles were retrieved, of which 17 were excluded (review articles, editorials and single-case reports). A total of 24 separate articles published between 1984 and 2018 were included in the final analysis, where the majority of patients harbored anterior circulation giant or large aneurysms. Adenosine-induced cardiac arrest gave a short, temporary asystole. The method had benefits in aneurysm with a broad neck, a thin wall, in specific localizations with narrow surgical corridors or in case of intraoperative rupture. Rapid ventricular pacing (RVP) allows a longer and more easily controlled hypotension. Its use is largely limited to elective cases. Deep hypothermic circulatory arrest required a complex infrastructure, and fatal procedure complications lead to a 11.5-30% 30-day mortality rate, limiting its application to giant or complex aneurysm of the basilar artery or to residual posterior circulation aneurysm after endovascular treatment. Adenosine and RVP are both effective options to facilitate clipping of complex aneurysms. However, their use in patient with ischemic heart disease and cardiac arrhythmias should be avoided, and their safety in the context of subarachnoid hemorrhage is yet to be determined. Today, deep hypothermic circulatory arrest is almost obsolete due to endovascular alternatives

Supratentorial Pediatric Midline Tumors and Tumor-like Lesions: Clinical Spectrum, Natural History and Treatment Options

Childhood Central Nervous System tumors account for 25% of all pediatric tumors. Large availability and broadening of indications to imaging has made incidental findings more common. Among these, midline lesions have different clinical relevance depending on their intrinsic pattern of behaviour and on their specific location. In this narrative review we describe the natural history and treatment options of midline lesions in children

Augmented reality in intracranial meningioma surgery: a case report and systematic review

Augmented Reality (AR) is as a useful and reliable tool in cranial surgery. We report the case of a left fronto-temporal meningioma in contact with the left Sylvian bifurcation, managed surgically with the aid of AR. We complete the picture with a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines

Trends and outcomes for non‑elective neurosurgical procedures in Central Europe during the COVID‑19 pandemic

The world currently faces the novel severe acute respiratory syndrome coronavirus 2 pandemic. Little is known about the efects of a pandemic on non-elective neurosurgical practices, which have continued under modifed conditions to reduce the spread of COVID-19. This knowledge might be critical for the ongoing second coronavirus wave and potential restrictions on health care. We aimed to determine the incidence and 30-day mortality rate of various non-elective neurosurgical procedures during the COVID-19 pandemic.A retrospective, multi-centre observational cohort study among neurosurgical centres within Austria, the Czech Republic, and Switzerland was performed. Incidence of neurosurgical emergencies and related 30-day mortality rates were determined for a period refecting the peak pandemic of the frst wave in all participating countries (i.e. March 16th–April 15th, 2020), and compared to the same period in prior years (2017, 2018, and 2019).A total of 4,752 emergency neurosurgical cases were reviewed over a 4-year period. In 2020, during the COVID-19 pandemic, there was a general decline in the incidence of non-elective neurosurgical cases, which was driven by a reduced number of traumatic brain injuries, spine conditions, and chronic subdural hematomas. Thirty-day mortality did not signifcantly increase overall or for any of the conditions examined during the peak of the pandemic.The neurosurgical community in these three European countries observed a decrease in the incidence of some neurosurgical emergencies with 30-day mortality rates comparable to previous years (2017–2019). Lower incidence of neurosurgical cases is likely related to restrictions placed on mobility within countries, but may also involve delayed patient presentation.Medicine, Faculty ofOther UBCNon UBCReviewedFacultyResearcherPostdoctora
