[Ab] Resumo:To investigate the characteristics of symptomatic trigeminal neuralgia (TN) caused by tumors and the relationship between anatomicosurgical findings and tumor type, the authors undertook a retrospective review of 35 patients with symptomatic TN between 2006 and 2015. The tumors included 16 meningiomas, 14 epidermoids, 4 vestibular schwannomas, and 1 hemangioblastoma. The studies show that patients with tumor-induced TN were significantly younger than those idiopathic TN (P <0.05). Meningioma-induced TN tended to have responsible vessels, while epidermoid tumor seemed to cause TN by wrapping or compressing the nerve. Additional vascular compression was observed in 15 (42.9%) of these 35 patients. All patients except one showed immediate pain relief following total or subtotal tumor removal with microvascular decompression (if required). Two patients with epidermoid-induced TN experienced symptom relapses caused by tumor regrowth, and one with meningioma-induced TN experienced pain recurrence caused by adhesive arachnoid. The key for operative success is to examine the entire nerve root for possible vascular compression after total or subtotal tumor resection.

[Ab] Resumo:Importance: Individuals with vestibular hypofunction acutely restrict head motion to reduce symptoms of dizziness and nausea. This restriction results in abnormal decoupling of head motion from trunk motion, but the character, magnitude, and persistence of these deficits are unclear. Objective: To use wearable inertial sensors to quantify the extent of head and trunk kinematic abnormalities in the subacute stage after resection of vestibular schwannoma (VS) and the particular areas of deficit in head-trunk motion. Design, Setting, and Participants: This cross-sectional observational study included a convenience sample of 20 healthy adults without vestibular impairment and a referred sample of 14 adults 4 to 8 weeks after resection of a unilateral VS at a university and a university hospital outpatient clinic. Data were collected from November 12, 2015, through November 17, 2016. Exposures: Functional gait activities requiring angular head movements, including items from the Functional Gait Assessment (FGA; range, 1-30, with higher scores indicating better performance), the Timed Up & Go test (TUG; measured in seconds), and a 2-minute walk test (2MWT; measured in meters). Main Outcomes and Measures: Primary outcomes included peak head rotation amplitude (in degrees), peak head rotation velocity (in degrees per second), and percentage of head-trunk coupling. Secondary outcomes were activity and participation measures including gait speed, FGA score, TUG time, 2MWT distance, and the Dizziness Handicap Inventory score (range, 0-100, with higher scores indicating worse performance). Results: A total of 34 participants (14 men and 20 women; mean [SD] age, 39.3 [13.6] years) were included. Compared with the 20 healthy participants, the 14 individuals with vestibular hypofunction demonstrated mean (SD) reduced head turn amplitude (84.1° [15.5°] vs 113.2° [24.4°] for FGA-3), reduced head turn velocities (195.0°/s [75.9°/s] vs 358.9°/s [112.5°/s] for FGA-3), and increased head-trunk coupling (15.1% [6.5%] vs 5.9% [5.8%] for FGA-3) during gait tasks requiring angular head movements. Secondary outcomes were also worse in individuals after VS resection compared with healthy individuals, including gait speed (1.09 [0.27] m/s vs 1.47 [0.22] m/s), FGA score (20.5 [3.6] vs 30.0 [0.2]), TUG time (10.9 [1.7] s vs 7.1 [0.8] s), 2MWT (164.8 [37.6] m vs 222.6 [26.8] m), and Dizziness Handicap Inventory score (35.4 [20.7] vs 0.1 [0.4]). Conclusions and Relevance: With use of wearable sensors, deficits in head-trunk kinematics were characterized along with a spectrum of disability in individuals in the subacute stage after VS surgery compared with healthy individuals. Future research is needed to fully understand how patterns of exposure to head-on-trunk movements influence the trajectory of recovery of head-trunk coordination during community mobility.

[Ti] Título:Management of Residual Tumor After Limited Subtotal Resection of Large Vestibular Schwannomas: Lessons Learned and Rationale for Specialized Care.

[Ab] Resumo:BACKGROUND: In an era where subtotal resection (STR) is increasingly used, we have encountered a growing number of patients referred to our institution with limited resection of large vestibular schwannomas (VSs), sometimes associated with grave complications. Our aim was to highlight lessons learned in the management of large VSs and provide a rationale for specialized care. METHODS: A prospectively maintained database of >2000 patients with VSs evaluated at our institution between 2000 and 2016 was reviewed. Details of 10 patients with residual tumor after limited subtotal resection were reviewed, with 3 presented in detail to illustrate key aspects of management. RESULTS: All but 1 patient underwent initial surgery at private hospitals without a designated skull base team. The median posterior fossa tumor diameter at the time of initial operation was 4.0 cm, whereas median diameter of residual tumor at the time of our evaluation was 3.5 cm. Before referral, 3 patients had undergone fractionated radiation therapy after their initial operation; 1 had undergone stereotactic radiosurgery. Four patients had moderate to severe facial weakness; 2 had permanent sequelae from stroke, including hemiparesis and blindness; and 7 had ongoing symptomatic brainstem compression and/or hydrocephalus. CONCLUSIONS: Management of large VSs remains challenging, including treating presenting hydrocephalus, maximizing extent of resection while optimizing facial nerve outcome, and avoiding complications. Most cases should be approached with the intent of complete resection, realizing that subtotal resection may become necessary based on intraoperative findings.

[Ab] Resumo:OBJECTIVES: The video-head-impulse test (vHIT) provides a functional assessment of all six semicircular canals (SCC). Occasionally isolated loss of the posterior canal(s) (ILPC) is diagnosed, though this finding is poorly characterized. Here we assessed how accurate that diagnosis is by measuring the co-occurrence of abnormalities on caloric irrigation, vestibular-evoked myogenic-potentials and audiometry. METHODS: We identified 52 patients with ILPC (unilateral=40, bilateral=12). We determined vHIT-gains and saccade-amplitudes and correlated vHIT-findings with other vestibulo-cochlear tests. RESULTS: The most frequent diagnoses were history of vestibular neuritis (13/52), Menière's disease (12/52) and vertigo/dizziness of unclear origin (13/52). Unilateral ILPC on vHIT was accompanied by a deficient horizontal canal on calorics, saccular and/or utricular deficits ipsilesionally in 33/40 (83%), while ipsilesional hearing-loss was noted in 24/40 (60%). Involvement of other sensors was highest for vestibular schwannoma (100%) and history of vestibular neuritis (92%). Bilateral deficits in ≥1 vestibulo-cochlear sensor(s) were noted in 2/12 cases with bilateral ILPC. CONCLUSIONS: >80% of patients with unilateral ILPC had additional deficits of other parts of the vestibular organ, while this rate was ≤20% for patients with bilateral ILPC. SIGNIFICANCE: Dizzy patients should receive testing of the posterior canals and if abnormalities are observed, additional vestibulo-cochlear testing should be obtained.

[Ti] Título:Probabilistic Multiple-Bias Modeling Applied to the Canadian Data From the Interphone Study of Mobile Phone Use and Risk of Glioma, Meningioma, Acoustic Neuroma, and Parotid Gland Tumors.

[Ab] Resumo:We undertook a re-analysis of the Canadian data from the 13-country case-control Interphone Study (2001-2004), in which researchers evaluated the associations of mobile phone use with the risks of brain, acoustic neuroma, and parotid gland tumors. In the main publication of the multinational Interphone Study, investigators concluded that biases and errors prevented a causal interpretation. We applied a probabilistic multiple-bias model to address possible biases simultaneously, using validation data from billing records and nonparticipant questionnaires as information on recall error and selective participation. In our modeling, we sought to adjust for these sources of uncertainty and to facilitate interpretation. For glioma, when comparing those in the highest quartile of use (>558 lifetime hours) to those who were not regular users, the odds ratio was 2.0 (95% confidence interval: 1.2, 3.4). After adjustment for selection and recall biases, the odds ratio was 2.2 (95% limits: 1.3, 4.1). There was little evidence of an increase in the risk of meningioma, acoustic neuroma, or parotid gland tumors in relation to mobile phone use. Adjustments for selection and recall biases did not materially affect interpretation in our results from Canadian data.

[Ab] Resumo:BACKGROUND: Further investigation is needed to look at the impact of vestibular schwannoma (VS) on the health-related quality of life (QOL) of participants who undergo Gamma Knife® radiosurgery (GKRS). OBJECTIVES: Investigators compared the QOL for VS participants to reported US population norms in order to evaluate disease burden and long-term QOL several years after GKRS. METHODS: This cross-sectional study surveyed participants to assess hearing status, tinnitus, imbalance, vertigo, as well as the Short-Form 36-item Health Questionnaire (SF-36). The data were normalized, age adjusted, and functional status was correlated to determine clinically significant differences. RESULTS: A total of 353 participants who underwent GKRS between 1997 and 2007 were included in this study with a median postoperative period of 5 years. SF-36 scores were very similar to population norms, and age-adjusted scores for participants followed the US population curve. Frequent vertigo and balance problems had the largest statistically and clinically significant effect on physical and mental component summary scores followed by nonuseful hearing in the tumor ear. CONCLUSIONS: Participants reported a good long-term QOL that was very similar to the QOL of US population norms. Of the common VS symptoms, vertigo had the greatest impact on QOL followed by imbalance and then hearing loss.
