Reporting of Participants' Sex, Race, Ethnicity, and Socioeconomic Status in Pituitary Surgery Literature.

 Social determinants of health (SDOH) are associated with differential outcomes after pituitary tumor treatment. However, the specific impact of SDOH is not well characterized. One reason may be the lack of collection and reporting of sociodemographic variables in the literature.

Microsurgical anatomy and approaches to thalamic gliomas. Part 1: A cartography guide for navigating to the thalamus. Integrating 3D model rendering with anatomical dissections.

Objective: The selection of appropriate microsurgical approaches to treat thalamic pathologies is currently largely subjective. The objective of this study was to provide a structured cartography map for surgical navigation to treat gliomas involving different surfaces of the thalamus.

Methods: Fifteen formalin-fixed, silicone-injected cadavers (30 sides) were dissected, and 10 adult brain specimens (20 sides) were used to illustrate thalamic microsurgical anatomy using the Klingler fiber dissection technique.

Microsurgical anatomy and approaches to thalamic gliomas. Part 2: Maximal safe resection of thalamic gliomas improves outcomes. A single-center experience.

Objective: As presented in Part 1 of this series, thalamic gliomas (TGs) are deep-seated, difficult-to-access tumors surrounded by vital neurovascular structures. Given their high operative morbidity, TGs have historically been considered inoperable lesions. Although maximal safe resection (MSR) has become the treatment standard for lobar and even deep-seated mediobasal temporal and insular gliomas, the eloquent location of TGs has precluded this management strategy, with biopsy and adjuvant treatment being the mainstay.

Developmentally Unique Cerebellar Processing Prioritizes Self- over Other-Generated Movements.

Animals must distinguish the sensory consequences of self-generated movements (reafference) from those of other-generated movements (exafference). Only self-generated movements entail the production of motor copies (i.e.

Blood-Brain Barrier Disruption for the Treatment of Primary Brain Tumors: Advances in the Past Half-Decade.

Purpose Of Review: To review relevant advances in the past half-decade in the treatment of primary brain tumors via modification of blood-brain barrier (BBB) permeability.

Recent Findings: BBB disruption is becoming increasingly common in the treatment of primary brain tumors. Use of mannitol in BBB disruption for targeted delivery of chemotherapeutics via superselective intra-arterial cerebral infusion (SIACI) is the most utilized strategy to modify the BBB.

Image-Based Assessment of Natural Killer Cell Activity against Glioblastoma Stem Cells.

Glioblastoma (GBM) poses a significant challenge in oncology and stands as the most aggressive form of brain cancer. A primary contributor to its relentless nature is the stem-like cancer cells, called glioblastoma stem cells (GSCs). GSCs have the capacity for self-renewal and tumorigenesis, leading to frequent GBM recurrences and complicating treatment modalities.

Developmentally unique cerebellar processing prioritizes self-over other-generated movements.

Animals must distinguish the sensory consequences of self-generated movements (reafference) from those of other-generated movements (exafference). Only self-generated movements entail the production of motor copies (i.e.

Predictors of Surgical Outcomes in Patients with Abducens Nerve Schwannoma: A Comprehensive Systematic Review and a Case Report.

Background: Abducens nerve (AN) schwannomas are extremely rare tumors. Clinical characteristics and factors that influence postoperative outcomes are not well defined.

Objective: To characterize clinical features of AN schwannomas and predictors of surgical outcomes.

Establishment and characterization of patient-derived xenograft of a rare pediatric anaplastic pleomorphic xanthoastrocytoma (PXA) bearing a CDC42SE2-BRAF fusion.

Pleomorphic xanthoastrocytoma (PXA) is a rare subset of primary pediatric glioma with 70% 5-year disease free survival. However, up to 20% of cases present with local recurrence and malignant transformation into more aggressive type anaplastic PXA (AXPA) or glioblastoma. The understanding of disease etiology and mechanisms driving PXA and APXA are limited, and there is no standard of care.

Methods: Complete author listings for neurosurgical oncology articles published between 1944 and 2021 in five top neuro-oncology journals were extracted from the PubMed database and journal websites on December 2, 2021. Author gender was characterized with the web application programming interface (API) genderize.

GammaTile for Gliomas: A Single-Center Case Series.

GammaTile® (GT Medical Technologies, Tempe, Arizona) is a surgically targeted radiation source, approved by FDA for brachytherapy in primary and secondary brain neoplasms. Each GammaTile is composed of a collagen sponge with four seeds of cesium 131 and is particularly useful in recurrent tumors. We report our early experience in seven patients with recurrent gliomas to assess this type of brachytherapy with particular attention to ease of use, complication, and surgical planning.

Hemoglobin Concentration May Influence the Incidence of Postoperative Transient Neurological Events in Patients With Moyamoya After Extracranial-intracranial Arterial Bypass: A Retrospective Single Center Experience.

Background: Moyamoya is a rare condition characterized by cerebral angiographic findings of intracranial carotid artery stenosis with abnormal net-like vessels in the brain, and often presents as transient ischemic attacks or intracranial hemorrhage. Revascularization in the form of extracranial-intracranial (EC-IC) artery bypass has demonstrated efficacy in preventing ischemic attacks and intracranial hemorrhage, although it is associated with a relatively high rate of perioperative ischemic and hemorrhagic stroke. This retrospective analysis aims to evaluate the possible association between postoperative hemoglobin (Hgb) concentration and early postoperative transient neurological events (TNEs) experienced at our center.

Fellowship, gender, and scholarly productivity: trends among academic neurosurgeons in the US.

Objective: Current data on fellowship choice and completion by neurosurgical residents are limited, especially in relation to gender, scholarly productivity, and career progression. The objective of this study was to determine gender differences in the selection of fellowship training and subsequent scholarly productivity and career progression.

Methods: The authors conducted a quantitative analysis of the fellowship training information of practicing US academic neurosurgeons.

Hair-sparing technique using absorbable intradermal barbed suture versus traditional closure methods in supratentorial craniotomies for tumor.

Background: Hair-sparing techniques in cranial neurosurgery have gained traction in recent years and previous studies have shown no difference in infection rates, yet limited data exists evaluating the specific closure techniques utilized during hair-sparing craniotomies. Therefore, it was the intention of this study to evaluate the rate of surgical site infections (SSIs) and perioperative complications associated with using an absorbable intradermal barbed suture for skin closure in hair-sparing supratentorial craniotomies for tumor in order to prove non-inferiority to traditional methods.

Methods: A retrospective review of supratentorial craniotomies for tumor by a single surgeon from 2011 to 2017 was performed.

Brain Tumor Surgery is Safe in Octogenarians and Nonagenarians: A Single-Surgeon 741 Patient Series.

Objectives: Elderly patients with surgically accessible brain tumors are often not offered clinically indicated brain tumor surgery (BTS) because of to assumptions of greater risk for perioperative morbidity and mortality. Because brain tumor incidence is highest in the geriatric population, and because the global population is aging, accurate understanding of BTS risk in elderly patients is critical. We aimed to compare safety of BTS in elderly patients with younger counterparts to better understand the risk-benefit profile of BTS for elderly patients.

The use of dehydrated amniotic membrane allograft for augmentation of dural repair in transsphenoidal endoscopic endonasal resection of pituitary adenomas.

Background: In transsphenoidal endoscopic endonasal surgery (TEES), watertight separation of the sinonasal cavity and intracranial compartment is the primary goal of closure. However, even when meticulous closure technique is implemented, cerebrospinal fluid (CSF) leaks, dural scarring, and meningitis may result. Particularly when intraoperative CSF leak occurs, materials that facilitate the creation of a watertight seal that inhibits disease transition and minimizes inflammatory response after durotomy are sought.

Predictors of Successful Discharge of Patients on Postoperative Day 1 After Craniotomy for Brain Tumor.

Background: Shorter hospital stays have been associated with decreased complication rates, fewer hospital-acquired infections, and lower costs. We evaluated an optimized treatment paradigm for patients undergoing craniotomy allowing for postoperative day 1 (POD1) discharge if the criteria were met. We compared the complication and readmission rates between the POD1 patients and those with longer stays, and examined the patient and surgical variables for predictors of POD1 discharge.
