Objective: To characterize the risk of progression to nonserviceable hearing in patients with sporadic vestibular schwannomas (VS) who elect initial observation. Study Design: Retrospective case series. Setting: Two tertiary care centers. Patients: VS patients with serviceable hearing who underwent at least two audiograms and two MRI studies before intervention or loss to follow-up. Main outcome measure(s): Serviceable hearing, defined as the pure tone average ≤ 50 dB HL and word recognition score ≥ 50%. Results: Four-hundred sixty-six patients (median age of 57 yr and median tumor diameter of 7.3 mm) had serviceable hearing at presentation and were followed for a median of 2.3 years (IQR 1.0 – 4.0). Kaplan–Meier estimated rates of maintaining serviceable hearing (95% CI; number still at risk) at 1, 3, 5, 7, and 10 years following diagnosis were 94% (91–96; 357), 77% (73–82; 172), 66% (60–73; 81), 56% (49–65; 31), and 44% (33–59; 10), respectively. Each 10-dB increase in pure-tone averages at diagnosis was associated with a 2-fold increased likelihood of developing nonserviceable hearing (hazard ratio 2.07; p < 0.001). Each 10% decrease in word recognition score was associated with a 1.5-fold increased likelihood of developing nonserviceable hearing (hazard ratio 1.48; p < 0.001). Conclusions: Among patients with sporadic VS, good baseline word recognition score and low pure-tone average are jointly associated with maintenance of serviceable hearing. These data may be used to guide patient counseling and optimize management.

AbstractObese children are at higher risk of developing psoriasis, and obesity severity is correlated with psoriasis severity. The relationship between obesity and pediatric psoriasis was explored in a well‐defined population. Obesity and psoriasis coexist at diagnosis, but it is likely that obesity commonly precedes psoriasis in children.

Objective: To describe the incidence of intralabyrinthine schwannoma (ILS) utilizing the Rochester Epidemiology Project (REP), a unique medical consortium in the United States that covers a complete population of all ages in a well-defined geographic area over the past half-century. Patients: All patients with ILS diagnosed between January 1, 1966 and December 31, 2016 in Olmsted County, Minnesota, identified using the REP medical records-linkage system. Main Outcome Measures: Incidence of ILS. Results: Fourteen incident cases of ILS were identified in Olmsted County since 1966—a period spanning 5.9 million person-years. Over the past decade, the incidence rate of ILS was 0.81 per 100,000 person-years and 1.1 over the last 5 years. Since 1966, the cumulative incidence rate of ILS over the past 50 years was 0.26 per 100,000 person-years. The median age at diagnosis was 60 years (interquartile ranges, 39–70). Incidence increased with age: over the last 5 years, those aged 60 to 69 exhibited an incidence rate of 2.7 per 100,000 person-years and those 70+ displayed a rate of 4.1. All patients had varying levels of asymmetrical sensorineural hearing loss with 64% of patients presenting with class D hearing. Four (29%) patients had a history of sudden sensorineural hearing loss, five (36%) reported imbalance and/or vertigo, and four (29%) reported aural fullness. Three of the 14 (21%) patients had neurofibromatosis type 2. Conclusion: The incidence of ILS exceeds 1 per 100,000 person-years with modern diagnostic imaging. The rising incidence of ILS in recent years most likely reflects improved capacity for disease detection rather than a true increase in tumor development. Given the reputability of the REP consortium, these data suggest that ILS comprises a more common entity than previously considered.

AbstractBackgroundShared decision making in the emergency department (ED) can increase patient engagement for patients presenting with chest pain. However, little is known regarding which factors are associated with actual patient involvement in decision making or patients’ desired involvement in emergency care decisions. We examined which factors were associated with patients’ actual and desired involvement in decision making among ED chest pain patients.MethodsThis is a secondary analysis of data from a randomized trial of a shared decision‐making intervention in ED patients with low‐risk chest pain. We evaluated the degree to which patients were involved in decision making using the OPTION‐12 (observing patient involvement) scale and patients’ reported desire for involvement in decision making using the Control Preferences Scale (CPS). We measured the associations of patient factors with OPTION‐12 and CPS scores using multivariable regression.ResultsOf the 898 patients enrolled, mean (±SD) age was 51.5 (±11.4) years and 59% were female. Multivariable analysis revealed that only two factors were significantly associated with OPTION‐12 scores: study site and use of the decision aid. OPTION‐12 scores were 10.3 (standard error = 0.6) points higher for patients randomized to the decision aid compared to usual care (p < 0.001). Higher health literacy was associated with lower scores on the CPS, indicating greater desire for involvement (odds ratio = 0.91, p < 0.001).ConclusionsPatients’ reported desire for involvement in decision making was higher among those with higher health literacy. After study site and other potential confounding factors were adjusted for, only use of the decision aid was associated with observed patient involvement in decision making. As the science and practice of shared decision making in the ED moves toward implementation, high‐fidelity integration of the decision aid into the flow of care will be necessary to realize desired outcomes.

AbstractBackgroundThe purpose of this study was to determine the clinical outcomes and review the management strategies for metastatic esthesioneuroblastoma.MethodsWe conducted a systematic review and meta‐analysis.ResultsForty‐eight studies totaling 118 patients met inclusion criteria. Chemotherapy in combination with surgery and/or radiation exhibited the best overall survival when compared to monotherapy and no treatment (P < .001). However, most patients (66%) received either monotherapy or no therapy. The number and location of metastases among the 3 treatment groups did not significantly differ (P = .85). Treatment modality remained significantly associated with overall survival on multivariable analysis (P < .001). Platinum‐based chemotherapy was most commonly utilized but did not provide a survival benefit when compared with all other regimens (P = .88).ConclusionDistant metastases with esthesioneuroblastoma portend a poor prognosis. Chemotherapy in combination with surgery and/or radiation was associated with improved overall survival. Further research into the optimal systemic therapeutic regimen for patients with distant metastases is critical.

Objective The absence of a centralized health system has limited epidemiologic research surrounding vestibular schwannoma (VS) in the United States. The Rochester Epidemiology Project (REP) comprises a unique medical consortium that covers a complete population of all ages in a well‐defined geographic region over the past half‐century. The objective of this study was to characterize the incidence of sporadic VS over this extended period. Study Design Population‐based study. Setting Olmsted County, Minnesota. Subjects and Methods Review of all VSs diagnosed between January 1, 1966, and December 31, 2016, was conducted with the REP medical records linkage system. Results A total of 153 incident cases of VS were identified. The incidence of VS significantly increased over the past half‐century from 1.5 per 100,000 person‐years during the first decade to 4.2 in the last decade ( P <. 001). Incidence increased with age ( P <. 001): those aged ≥70 years exhibited the highest incidence rate at 18.3 per 100,000 person‐years in the last decade. Age at diagnosis significantly increased from a median of 52 years in the first decade to 62 years in the last ( P <. 001). Despite presenting with fewer symptoms and smaller tumors, the time delay between symptom onset and diagnosis significantly decreased over the past 5 decades (all P <. 05). Almost 1 in 4 patients was diagnosed incidentally in the last decade. Conclusion The incidence of VS increased significantly over the past half‐century to a rate greater than previously reported. Patients’ ease of access to medical care in Olmsted County and the comprehensive REP system likely contributed to this elevated detection rate of VS.

Objective(1) Assess 3‐dimensional volumetric growth of untreated sporadic vestibular schwannomas (VSs) in a large cohort of patients treated with conservative observation. (2) Compare volumetric and conventional linear diameter measurements for detecting tumor growth.Study DesignCase series with chart review.SettingTertiary skull base referral center.Subjects and MethodsPatients with sporadic VS who elected initial conservative treatment with at least 2 serial magnetic resonance imaging (MRI) scans were included. Tumor volume was determined with 3‐dimensional segmentation of MRI sequences. The volumetric threshold for tumor growth was an increase ≥20% from baseline tumor volume. Tumor size based on linear diameter was assessed with the 1995 American Academy of Otolaryngology—Head and Neck Surgery Foundation guidelines for VS outcome reporting, with growth defined as an increase ≥2 mm.ResultsA total of 361 patients were included with a median radiologic follow‐up of 4.1 years (interquartile range [IQR], 2.5‐6.8). At diagnosis, 232 VSs (64%) were purely intracanalicular, and 129 (36%) extended into the cerebellopontine angle. The median baseline tumor volume was 0.161 cm3 (IQR, 0.054‐0.418). Overall, 69% of tumors demonstrated volumetric growth at a median of 1.1 years (IQR, 0.6‐2.1) after initial MRI. In contrast, based on linear measurement assessment, 48% of tumors demonstrated growth at a median of 1.8 years (IQR, 0.8‐3.1) from first MRI scan. Disequilibrium, facial hypoesthesia, aural fullness, initial tumor size, and nonincidental diagnosis were associated with tumor growth.ConclusionThree‐dimensional volumetric assessment of VS provides a more sensitive measure of tumor growth when compared with linear diameter assessment. Through volumetric analysis, the current study revealed that a significant proportion of VSs demonstrate growth during observation.
