Worse Outcomes After Repeat vs Initial Stereotactic Radiosurgery for Cerebral Arteriovenous Malformations: A Retrospective Matched-Cohort Study.
Incompletely obliterated cerebral arteriovenous malformations (AVMs) after initial treatment with stereotactic radiosurgery (SRS) can be treated with a repeat session of SRS. However, the relative efficacy of repeat vs initial SRS is not well specified. ⋯ AVM, arteriovenous malformationRIC, radiation-induced changeRBAS, radiosurgery-based arteriovenous malformation scoreSRS, stereotactic radiosurgeryVRAS, virginia radiosurgery AVM scale.

Invasive neuromodulation of the cortical surface for various chronic pain syndromes has been performed for >20 years. The significance of motor cortex stimulation (MCS) in chronic trigeminal neuropathic pain (TNP) syndromes remains unclear. Different techniques are performed worldwide in regard to operative procedure, stimulation parameters, test trials, and implanted materials. ⋯ MCS, motor cortex stimulationNRS, numeric pain rating scaleTNP, trigeminal neuropathic or deafferentation painVAS, visual analog scale.

Antiplatelet therapy in patients with chronic subdural hematoma (cSDH) presents significant neurosurgical challenges. Given the lack of guidelines regarding perioperative management with antiplatelet therapy, it is difficult to balance the patient's increased cardiovascular risk and prevalence of cSDH. ⋯ ASA, acetylsalicylic acidCAD, coronary artery diseaseCI, confidence intervalcSDH, chronic subdural hematomaGCS, Glasgow Coma ScalemRS, modified Rankin ScaleOR, odds ratioRD, risk difference.

Cervical spondylotic myelopathy (CSM) is a common disease of aging that leads to gait instability resulting from loss of leg sensory and motor functions. The results of surgical intervention have been studied using a variety of methods, but no test has been reported that objectively measures integrative leg motor sensory functions in CSM patients. ⋯ BW, body weightCSM, cervical spondylotic myelopathymJOA, modified Japanese Orthopedic AssociationSLS, single leg squat.

Glioblastoma is the most common and aggressive primary brain tumor. Despite current treatment, recurrence is inevitable. There are no clear guidelines for treatment of recurrent glioblastoma. ⋯ ECOG, Eastern Cooperative Oncology GroupEOR, extent of resectionIDH-1, isocitrate dehydrogenase 1IP, inpatientMGMT, O-methylguanine methyltransferaseOS, overall survivalPFS, progression-free survivalRMH, Royal Melbourne Hospital.
