Abstract

Cranioplasty with titanium mesh provides a stable and cosmetically sound option for the correction of extensive skull bone defects following trauma or tumour surgery with osseous involvement. Meningiomas are for the most part benign lesions that are amenable to surgical cure, however lesions with extradural extension pose additional challenges not only due to increased technical difficulty in achieving gross total resection but also because of distinct biological behaviour. We describe the case of a 43-years-old woman that had been submitted to gross total resection of a WHO grade I falcine and superior sagittal sinus secretory meningioma with extradural and bone extension and cranioplasty with a titanium mesh who had a recurrence 4 years later as two tumour masses on top of the titanium mesh with no adjacent soft tissue invasion, and without dural involvement. To our knowledge, this is the first reported case of meningioma growth on top of titanium cranioplasty material. Seeded or incompletely removed tumoral cells might have exploited the biocompatibility of titanium to promote tumour regrowth. [ABSTRACT FROM AUTHOR]

Abstract

Background and Objectives The efficacy of deep brain stimulation of the anterior nucleus of the thalamus (ANT DBS) in patients with drug-resistant epilepsy (DRE) was demonstrated in the double-blind Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy randomized controlled trial. The Medtronic Registry for Epilepsy (MORE) aims to understand the safety and longer-term effectiveness of ANT DBS therapy in routine clinical practice. Methods MORE is an observational registry collecting prospective and retrospective clinical data. Participants were at least 18 years old, with focal DRE recruited across 25 centers from 13 countries. They were followed for at least 2 years in terms of seizure frequency (SF), responder rate (RR), health-related quality of life (Quality of Life in Epilepsy Inventory 31), depression, and safety outcomes. Results Of the 191 patients recruited, 170 (mean [SD] age of 35.6 [10.7] years, 43% female) were implanted with DBS therapy and met all eligibility criteria. At baseline, 38% of patients reported cognitive impairment. The median monthly SF decreased by 33.1% from 15.8 at baseline to 8.8 at 2 years (p < 0.0001) with 32.3% RR. In the subgroup of 47 patients who completed 5 years of follow-up, the median monthly SF decreased by 55.1% from 16 at baseline to 7.9 at 5 years (p < 0.0001) with 53.2% RR. High-volume centers (>10 implantations) had 42.8% reduction in median monthly SF by 2 years in comparison with 25.8% in low-volume center. In patients with cognitive impairment, the reduction in median monthly SF was 26.0% by 2 years compared with 36.1% in patients without cognitive impairment. The most frequently reported adverse events were changes (e.g., increased frequency/severity) in seizure (16%), memory impairment (patient-reported complaint, 15%), depressive mood (patient-reported complaint, 13%), and epilepsy (12%). One definite sudden unexpected death in epilepsy case was reported. Discussion The MORE registry supports t
