ReviewGenetics and molecular pathophysiology of normal pressure hydrocephalus.
Idiopathic normal pressure hydrocephalus (iNPH) is characterized by dilation of the cerebral ventricles without increased cerebral pressure. Patients typically present with cognitive impairment, gait abnormalities, and urinary incontinence. ⋯ Familial cases and genomic studies of iNPH have recently suggested an underappreciated role of genetics in disease pathogenesis, implicating mechanisms ranging from dysregulated CSF dynamics to underlying neurodegenerative or neuroinflammatory processes. In this paper, the authors provide a brief review of genetic insights and candidate genes for iNPH, highlighting the continued importance of integrated genetic analysis and clinical studies to advance iNPH management.

Comparative StudyThe impact of general anesthesia versus non-general anesthesia on thrombectomy outcomes by occlusion location: insights from the ETIS registry.
Identifying the optimal anesthetic technique for mechanical thrombectomy (MT) remains an unresolved issue. Prior research has not considered the influence of occlusion site when comparing general anesthesia (GA) with non-GA. This study evaluates the differential impacts of the anesthetic technique (GA vs non-GA) on outcomes according to the location of occlusion. ⋯ While GA and non-GA techniques did not differ significantly in functional outcomes, the influence of GA on angiographic and procedural safety outcomes was location dependent, underscoring the importance of a tailored anesthesia technique in MT procedures.

Multicenter StudyA taxonomy for cerebellar cavernous malformations: subtypes of cerebellar lesions.
An anatomical taxonomy has been established to guide surgical approach selection for resecting brainstem and deep and superficial cerebral cavernous malformations (CMs). The authors propose a novel taxonomy for cerebellar CMs, introduce 6 distinct neuroanatomical subtypes, and assess their clinical outcomes. ⋯ Most cerebellar CMs are convexity lesions that do not require deep dissection. However, transsulcal and fissural approaches are used for those beneath the cerebellar surface to minimize tissue transgression and preserve associated function. Complete resection without any new deficit is accomplished in most patients. The proposed taxonomy for cerebellar CMs (suboccipital, tentorial, petrosal, vermian, tonsillar, and deep nuclear) guides the selection of craniotomy and approach to enhance patient safety and optimize neurological outcomes.

Core outcomes in nerve surgery: development of a core outcome set for common peroneal (fibular) neuropathy.
Common peroneal (fibular) neuropathy is the most common mononeuropathy of the lower extremity. Despite this, there are surprisingly few studies on the topic, and a knowledge gap remains in the literature. As one attempts to address this knowledge gap, a core outcome set (COS) is needed to guide the planning phases of future studies to allow synthesis and comparability of these studies. The objective of this study was to develop the COS-common peroneal neuropathy (CoPe) using a modified Delphi approach. ⋯ The COINS Consortium developed a consensus COS and provided definitions, methods of implementation, and time points for assessment. The COS-CoPe should serve as a minimum set of data that should be collected in all future neurosurgical studies on common peroneal neuropathy. Incorporation of this COS should help improve consistency in reporting, data synthesis, and comparability, and should minimize outcome reporting bias.

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.
