Functional mapping of movement and speech using task-based electrophysiological changes in stereoelectroencephalography.
Stereoelectroencephalography (SEEG) has become the predominant method for intracranial seizure localization. When imaging, semiology, and scalp EEG findings are not in full agreement or definitively localizing, implanted SEEG recordings are used to test candidate seizure onset zones (SOZs). Discovered SOZs may then be targeted for resection, laser ablation, or neurostimulation. If an SOZ is eloquent, resection and ablation are both contraindicated, so identifying functional representation is crucial for therapeutic decision-making. The authors present a novel functional brain mapping technique that utilizes task-based electrophysiological changes in SEEG during behavioral tasks and test this in pediatric and adult patients. ⋯ Task-based electrophysiological mapping using broadband changes in the SEEG signal reliably identifies movement and speech representation in pediatric and adult epilepsy patients.

Efficacy of subcutaneous sumatriptan in postcraniotomy pain and opioid consumption.
Traditional pain management pathways following craniotomy are predicated on opioids. However, narcotics can confound critical neurological examination, contribute to respiratory depression, lower the seizure threshold, and lead to medication habituation, dependence, and/or abuse. Alternative medications to better address postoperative pain while mitigating opioid-related adverse effects remain insufficiently studied. Preliminary studies suggest sumatriptan, a 5-HT (1B/1D) receptor agonist known to regulate dural vasoactivity and inflammation, may moderate pain following trigeminal microvascular decompression and chronic postcraniotomy headache. In this study, the authors evaluated the efficacy of sumatriptan to modulate pain and opioid requirements following craniotomy surgery. ⋯ Postoperative single-dose subcutaneous sumatriptan following elective craniotomy may reduce pain scores and opioid requirements. Additional studies are needed to better understand nuanced differences in opioid modulation and optimal patient selection.

Observational StudyImpact of standardized care guidelines featuring next-day discharge on outcome, healthcare consumption, and patient healthcare experience in patients with idiopathic normal pressure hydrocephalus receiving ventriculoperitoneal shunts.
The aim of this study was to evaluate the effect of standardized care guidelines featuring next-day discharge on hospital length of stay (LOS), outcomes, patient experience, and healthcare consumption in patients receiving ventriculoperitoneal shunts (VPSs) for idiopathic normal pressure hydrocephalus (iNPH). ⋯ Standardized discharge guidelines featuring next-day discharge are safe for iNPH patients undergoing VPS surgery, maintain the quality of the patient experience, and are an effective method for mitigating healthcare consumption in an expanding patient group.

Sublabial transmaxillary approach to the inferior aspect of the orbit.
The objective was to demonstrate the surgical steps and outcomes of the sublabial transmaxillary microsurgical approach with endoscopic assistance to treat lesions in the inferior aspect of the orbit, as well as to describe the use of patient-specific 3D models to facilitate surgical preparation and improve experience with the technique. ⋯ The sublabial transmaxillary approach is a direct and safe method to resect cavernous malformations at the inferior aspect of the orbit. It reduces the risk of complications associated with lateral, transcranial, and transnasal approaches that may cross critical structures. The microsurgical approach provides the benefit of two-handed dissection for lesions embedded in orbital fat, which can be challenging because of adhesions to surrounding tissues. The use of 3D models can facilitate surgical planning and enhance familiarity with the approach.
