Socioeconomic determinants impact quality of life at vestibular schwannoma diagnosis.

BACKGROUND: Socioeconomic variables including race, education, and income have been shown to affect vestibular schwannoma incidence, treatment, and outcomes. We sought to determine the impact of socioeconomic factors on quality of life at the time of vestibular schwannoma diagnosis. METHODS: Retrospective cohort study conducted at a tertiary academic center. All patients evaluated for vestibular schwannoma from March 1, 2010 to December 31, 2021 who completed at least one Penn Acoustic Neuroma Quality of Life (PANQOL) questionnaire at presentation or prior to any intervention were included. PANQOL scores were compared across income quintiles, racial groups, and health insurance categories. RESULTS: Two-hundred and ninety-six patients who had non-missing information on variables of interest were included. Compared to White/Caucasian patients (84.5 %), Black/African American patients (4.7 %) had significantly lower PANQOL total scores (b = -12.8[-21.7, -4.0], p = 0.005). Compared to patients with Commercial insurance (53 %), patients who were Uninsured/ Self-pay (1.7 %) had significantly lower PANQOL total scores (b = -16.7[-31.4, -1.9], p = 0.027). Patients in higher income quintiles had significantly higher PANQOL total scores (b = 11.7[3.9, 19.5], p = 0.004 comparing highest income quintile to lowest). After controlling for potential confounders, income quintile (b = 9.6[1.3, 17.9], p = 0.023 comparing highest quintile to lowest) and insurance (b = -17.0[-31.9, -21], p = 0.025 comparing Uninsured/Self-pay to Commercial insurance) remained predictors of total PANQOL score. CONCLUSIONS: Socioeconomic factors including race, health insurance, and income appear to contribute to quality of life at the time of vestibular schwannoma diagnosis. These variables are interrelated and the effects of race may be mediated in part by differences in income and health insurance coverage.

Single center experience using 3†mm trevo stent retrievers in medium vessel occlusion thrombectomy.

BACKGROUND: Endovascular mechanical thrombectomy has been shown to benefit select patients with acute ischemic stroke caused by medium vessel occlusion, aided by recent advancements in endovascular mechanical thrombectomy devices that facilitate navigation through narrower vasculature. In this study, we aim to evaluate the safety and efficacy of using the 3 mm Trevo NXT stent retriever (Stryker, Kalamazoo, MI) for endovascular mechanical thrombectomy in patients with acute ischemic stroke caused by medium vessel occlusion. METHODS: From our single-center registry, we performed a retrospective review of all acute ischemic stroke patients from 2018 to 2022 who underwent endovascular mechanical thrombectomy for medium vessel occlusion with a 3 mm Trevo NXT. We examined efficacy outcomes (modified thrombolysis in cerebral infarction and puncture-to-revascularization time), clinical outcomes (National Institutes of Health Stroke Scale), and procedural complication rate. RESULTS: Between 2018 and 2022, 44 patients (52.2% female, mean age 71.1 years, median National Institutes of Health Stroke Scale of 15 [8-22.8]) met our inclusion criteria. The 3 mm Trevo NXT was used in the first pass in 56.9% of individuals, with 72.4% achieving successful recanalization (modified thrombolysis in cerebral infarction ≥ 2B). The 3 mm Trevo NXT was used as "rescue" after initial revascularization failure in 43.1% of individuals, achieving successful recanalization in 60.0% of passes. Acute complications were reported in 2.4% of cases. Median National Institutes of Health Stroke Scale at 24 h after intervention was 12 (4-20.8). CONCLUSIONS: Our results suggest that endovascular mechanical thrombectomy using the 3 mm Trevo NXT is a safe and effective treatment option for medium vessel occlusion. The utility of novel stent retrievers in the treatment of medium vessel occlusion should be further explored in future multicenter studies.

A Rare Case of Cochlear Implant Electrode Array Misplacement Into the Posterior Semicircular Canal.

Cochlear implant electrode array misplacement is a rare but serious complication that may result in failure of hearing rehabilitation, non-auditory percepts, vestibular disturbance, or damage to adjacent neurovascular structures. We present a case of an elderly patient who suffered electrode array misplacement into the posterior semicircular canal, resulting in vestibular symptoms and severe downstream sequelae. The risk of misplacement may be higher in patients with a history of chronic otitis media or prior otologic surgery, and with the use of pre-curved electrode arrays. Electrophysiological testing and intraoperative imaging may allow for early detection and intervention in these cases. Laryngoscope, 133:175-177, 2023.
