Surgical management of patients with Eagle syndrome.

OBJECTIVE: Eagle syndrome, a spectrum of disease resulting from an elongated styloid process and/or calcified stylohyoid ligament, lacks standardized recommendations regarding indications for surgical intervention and approach. STUDY DESIGN: Retrospective cohort study. SETTING: Single tertiary care institution. SUBJECTS: Patients treated surgically for Eagle syndrome between January 2011 and June 2017. METHODS: Patients were diagnosed with Eagle syndrome based on thorough clinical workup and assessment. The primary outcome was improvement in pain severity following surgery, with complete resolution of pain being considered clinically meaningful. Wilcoxon rank-sum tests and Fisher's exact were used to compare numerical and categorical variables, respectively. RESULTS: Twenty-one patients were diagnosed with Eagle syndrome and underwent surgical resection of the styloid process. Patients most often complained of neck pain (81%), throat pain (62%), and ear pain (48%). Among these patients, 57% of procedures featured a transcervical approach, while the remaining 43% were transoral. The vast majority (90%) of patients experienced improvement in pain severity from a median of 6.0 before surgery to 0.0 afterwards (p < 0.01) as 62% experienced complete resolution. Using multivariable linear regression to model changes in pain severity, neck pain (ß = -1.69, p < 0.01) and jaw pain (ß = -0.93, p = 0.03) predicted greater relief, while headache (ß = 0.82, p = 0.04) predicted an inferior response. Adverse events were uncommon and typically resolved within three months, with 24% experiencing first bite syndrome and 19% reporting numbness. CONCLUSIONS: Transcervical and transoral styloidectomy are effective treatments for Eagle syndrome with minimal adverse effects. Patients with classic symptoms of neck or jaw pain benefit most from surgery.

Cognitive impairment after chemotherapy related to atypical network architecture for executive control.

OBJECTIVES: A common complaint of cancer patients is the experience of cognitive difficulty during and after chemotherapy. We hypothesized that cognitive impairment may result from dysfunction in large-scale brain networks, particularly those involved in attentional control. METHODS: Using a case-control design, this study includes women with a history of invasive ductal or lobular triple-negative breast cancer who completed standard adjuvant chemotherapy within 2 years of study entry. Women who reported cognitive impairment by the Global Rating of Cognition question were considered to be cases (n = 15). Women who reported no cognitive impairment were considered to be controls (n = 13). All enrolled participants were eligible for MRI investigation and underwent resting-state functional connectivity MRI. RESULTS: Women who self-reported cognitive impairment were found to have disrupted resting-state functional connectivity, as measured by MRI, when compared to women who did not self-report cognitive impairment. These findings suggest that some women may be more sensitive to the standard treatments for breast cancer and that this increased sensitivity may result in functional connectivity alterations in the brain networks supporting attention and executive function. CONCLUSIONS: Neuroimaging analyses confirmed self-reported cognitive deficits in women with breast cancer treated with chemotherapy.

Cost-effective Analysis of Subcutaneous vs Sublingual Immunotherapy From the Payor's Perspective.

OBJECTIVE: Compare the cost-effectiveness of subcutaneous immunotherapy (SCIT) and aqueous sublingual immunotherapy (SLIT) as treatment modalities for adult patients with allergic rhinitis and conjunctivitis who undergo testing and qualify for allergen immunotherapy (AIT). METHODS: A systematic review was performed to identify key statistics for analysis, including the compliance and efficacy rates for each treatment. The body of literature on this topic is highly heterogeneous, so ranges were obtained and assumptions stated clearly where they were made. Charges were derived from average commercial payor charges from a single hospital institution. A hypothetical 100 patients are examined for the study. RESULTS: A cost-effectiveness sensitivity analysis was then performed using a decision tree model to compare the modalities. A sensitivity and threshold analysis was then performed to assess the strength of recommendations after identifying results at baseline. DISCUSSION: Assuming an 80% compliance rate with allergen immunotherapy and an estimated efficacy (assumed to be clinically significant improvement in symptoms) of 70% for SLIT and 80% for SCIT, at the 12-month mark, the baseline total cost to the payor of SLIT per successful treatment outcome is $1196 while the charge of SCIT per successful treatment outcome is $2691. Our analysis favors SLIT as the more cost-effective modality per successful outcome. IMPLICATIONS FOR PRACTICE: When compared to SCIT, SLIT is economically favorable and should be considered the financially conscious option for patients with >40% adherence to therapy.

Cognitive Training for Adults With Bothersome Tinnitus: A Randomized Clinical Trial.

Importance: Individuals with tinnitus have poorer working memory, slower processing speeds and reaction times, and deficiencies in selective attention, all of which interfere with readiness and performance. Brain Fitness Program-Tinnitus (BFP-T) is a cognitive training program specially designed to exploit neuroplasticity for preservation and expansion of cognitive health in adults with tinnitus. Objective: To evaluate the effect of the BFP-T on tinnitus. Design, Setting, and Participants: This open-label, intention-to-treat randomized clinical trial prescreened 191 patients with tinnitus and 64 healthy controls (HCs) from June 1, 2012, through October 31, 2013. Participants were 40 adults with bothersome tinnitus for more than 6 months and 20 age-matched HCs. Patients with tinnitus were randomized to a BFP-T or non-BFP-T control group. The BFP-T was completed online, and assessments were completed at Washington University School of Medicine. Interventions: Participants in the intervention group were required to complete the BFP-T online 1 hour per day 5 days per week for 8 weeks. Tinnitus assessment, neuroimaging, and cognitive testing were completed at baseline and 8 weeks later. The HCs underwent neuroimaging and cognitive assessments. Main Outcomes and Measures: The primary outcome measure was the change in Tinnitus Handicap Inventory (THI) score. Behavioral measures, neuroimaging, and cognitive tests were performed before and after the intervention. Results: A total of 40 patients with tinnitus and 20 HCs participated in the study (median [range] age, 56 [35-64] years in the BFP-T group, 52 [24-64] years in the non-BFP-T group, and 50 [30-64] years in the HC group; 13 [65%] in the BFP-T group, 14 [70%] in the non-BFP-T group, and 13 [65%] in the HC group were males; and 16 [80%] in the BFP-T group, 16 [80%] in the non-BFP-T group, and 15 [75%] in the HC group were white). There was a reduction in the THI score in the BFP-T group (median, 7; range, -16 to 64) and non-BFP-T group (median, 11; range, -6 to 26), but this reduction was not significantly different between the 2 groups (median difference, 0; 95% CI, -10 to 8). There was no difference in cognitive test scores and other behavioral measures. There was a significant difference between baseline and follow-up in functional connectivity in cognitive control regions in the BFP-T group but not in HCs or individuals with untreated tinnitus. Of the 20 patients in the BFP-T group, 10 (50%) self-reported improvement attributable to the intervention, and 6 (30%) reported to be much improved in the domains of tinnitus, memory, attention, and concentration. Conclusions and Relevance: These findings suggest that the computer-based cognitive training program is associated with self-reported changes in attention, memory, and perception of tinnitus. A possible mechanistic explanation for these changes could be neuroplastic changes in key brain systems involved in cognitive control. Cognitive training programs might have a role in the future treatment of patients with tinnitus. Trial Registration: clinicaltrials.gov Identifier: NCT01458821.

Effects of mindfulness based stress reduction therapy on subjective bother and neural connectivity in chronic tinnitus.

OBJECTIVE: To evaluate the impact of a Mindfulness Based Stress Reduction (MBSR) program in patients with chronic bothersome tinnitus on the (1) severity of symptoms of tinnitus and (2) functional connectivity in neural attention networks. STUDY DESIGN: Open-label interventional pilot study. SETTING: Outpatient academic medical center. SUBJECTS: A total of 13 adult participants with a median age of 55 years, suffering from bothersome tinnitus. METHODS: An 8-week MBSR program was conducted by a trained MBSR instructor. The primary outcome measure was the difference in patient-reported tinnitus symptoms using the Tinnitus Handicap Index (THI) and Tinnitus Functional Index (TFI) between pre-intervention, post-MBSR, and 4-week post-MBSR assessments. Secondary outcomes included change in measurements of depression, anxiety, mindfulness, and cognitive abilities. Functional connectivity magnetic resonance imaging (MRI) was performed at pre- and post-MBSR intervention time points to serve as a neuroimaging biomarker of critical cortical networks. RESULTS: Scores on the THI and TFI showed statistically significant and clinically meaningful improvement over the course of the study with a median ΔTHI of -16 and median ΔTFI of -14.8 between baseline and 4-week follow-up scores. Except for depression, there was no significant change in any of the secondary outcome measures. Analysis of the resting state functional connectivity MRI (rs-fcMRI) data showed increased connectivity in the post-MBSR group in attention networks but not the default network. CONCLUSION: Participation in an MBSR program is associated with decreased severity in tinnitus symptoms and depression and connectivity changes in neural attention networks. MBSR is a promising treatment option for chronic bothersome tinnitus that is both noninvasive and inexpensive.

Exploring SEER-Medicare for changes in the treatment of laryngeal cancer among elderly medicare beneficiaries.

OBJECTIVE: To explore the change in frequency of treatment, and its association with 5-year survival, among elderly Medicare enrollees with squamous cell carcinoma of the larynx (SCCL). STUDY DESIGN: Retrospective analysis of a national cancer database. SUBJECTS AND METHODS: This was an analysis of the Surveillance, Epidemiology, and End Results (SEER)-Medicare data set of elderly patients diagnosed with SCCL between 1992 and 2007. Surgical and nonsurgical treatments were identified, and changes in frequency by year of cancer diagnosis were explored. A propensity-matched multivariate Cox proportional hazards model was used to compare the impact of treatment. RESULTS: There were 3324 cases of primary SCCL diagnosed between 1992 and 2007 studied. Most were male (n = 2605; 78%), white (n = 2845; 87%), and between 66 and 74 years of age (n = 1874; 56%). Between 1992 and 2005, there was a significant trend for increasing 5-year overall survival (43% in 1992 to 54% in 2005-2007; P < .01). There was a significant trend for decreasing frequency of surgical therapy (47% in 1992-1995 to 41% in 2005-2007; P = .03). Surgical therapy was associated with a decreased risk of overall mortality (hazard ratio, 0.76; 95% confidence interval, 0.68-0.86) in comparison to nonsurgical treatments. CONCLUSION: The analysis demonstrates an increase in survival among elderly Medicare enrollees diagnosed with SCCL between 1992 and 2007. Despite a significant trend for its decreasing use, there was a significantly decreased risk of overall mortality associated with surgical therapy.
