ReviewOutcomes following surgical intervention for acute hemorrhage in severe traumatic brain injury: a review of the National Trauma Data Bank.
Severe traumatic brain injury (TBI) is a public health issue posing significant morbidity and mortality to afflicted patients. While the effect of time to surgery as the primary factor for survival has been extensively studied, long-term dispositional outcomes following intracranial hemorrhage evacuation have not been well described in the literature. Therefore, the aim of this study was to elicit potential prognostic factors in patients presenting with severe TBI that may have a significant impact on discharge disposition. ⋯ Neurosurgical evacuation of intracranial hemorrhage in severe TBI has variable long-term morbidity. Utilizing the largest collection of trauma data within the United States, the authors present quantitative evidence on discharge disposition. Understanding these tangible points can help neurosurgeons present potential outcomes to patients, promote preventative care, and generate tangible conversations with patients and their family members.

ReviewOncolytic viral therapy: a review and promising future directions.
Oncolytic viral therapy is quickly emerging as a promising subset of immunotherapy, which theoretically can target tumor cells while sparing surrounding healthy cells by harnessing the replication machinery of viruses with tropism for tumor cells, resulting in direct oncolysis, and by transforming immunologically "cold" tumor into areas that elicit the host's immune response. This review provides an overview of oncolytic viral therapy until the present day, starting with the original concept in 1912. The general mechanism of oncolytic viruses (OVs) depends on selectively integrating them into tumor cells based on genetic engineering of viral genomic material, inducing oncolysis and eliciting the host's innate immune response. ⋯ In particular, the lack of an optimal delivery method based on tumor type for oncolytic viral therapy poses a significant obstacle, even in clinical studies. Intrathecal continuous delivery of OVs is a promising prospect, potentially by adapting the novel continuous irrigation and drainage IRRAflow catheter. Further exploration and testing of the IRRAflow catheter should be undertaken.

Multicenter StudyGrade 3 meningioma survival and recurrence outcomes in an international multicenter cohort.
Grade 3 meningioma represents a rare meningioma subtype, for which limited natural history data are available. The objective of this study was to identify demographics and pathologic characteristics, clinical and functional status outcomes, and prognostic factors in an international cohort of grade 3 meningioma patients. ⋯ This large multicenter study provides insight into the longitudinal outcomes of grade 3 meningioma, with respect to recurrence, survival, and functional status. This study affirms the survival benefit conferred by radiotherapy in this population and suggests good functional status outcomes for patients surviving to 5 years postoperatively.

When biopsy goes wrong: a case series of misdiagnoses and complications from biopsies of masses of unknown origin potentially originating from a peripheral nerve.
Biopsies of peripheral nerve tumors (PNTs) are often used to plan an efficient treatment strategy. However, performing a biopsy is controversial when the mass is likely to be a benign PNT (BPNT). The aim of this study was to evaluate the side effects of biopsies in patients with potential PNTs. ⋯ Biopsies of PNTs are controversial and may result in misdiagnosis, neuropathic pain, or neurological deficit due to axonal damage, and they may also hinder microsurgical resection when if performed when not indicated. Indications for biopsy of an MUOPON must be carefully considered, especially if BPNT is a possible diagnosis.

How a Scoville aneurysm clip fought in the Cold War and helped to establish neurosurgery in Iceland.
It can be said that the specialty of neurosurgery in Iceland had its beginnings on November 30, 1971, with the arrival of a huge American C-130 Hercules aircraft. It was carrying a small package containing Scoville aneurysm clips. They were sent to the late Bjarni Hannesson (1938-2013), who had received his neurosurgical training in 1967-1971 at the Dartmouth-Hitchcock Medical Center (then known as Mary Hitchcock Memorial Hospital and located in Hanover, New Hampshire). ⋯ It involved the continued presence of the American base at Keflavík, where the C-130 landed. The base was under pressure to be closed by Iceland's left-leaning, nominally communist government. The C-130's arrival generated welcome publicity for the continued operation of the American base, which is still there.
