Abstract
OBJECTIVE In the treatment of inner ear conditions, intratympanic injection emerges as an important drug delivery method. Novel compounds designed for intratympanic injection are routinely loaded in viscous drug carriers. To date, it is unclear if they can freely distribute in the middle ear. The aims of this study were to investigate the middle ear distribution of different drug carriers during intratympanic injection and to determine an optimal injection method for thermosensitive hydrogels. METHODS Twenty-one human temporal bones were intratympanically injected with fluid drug carriers or poloxamer-407 hydrogels at different tympanic membrane injection sites (inferior, anterior-superior) using different needle types (Whitacre, Quincke). Fluid distribution was evaluated via an endoscopic view. Injection volume, duration, backflow, and overall safety were analyzed. RESULTS Liquid drug carriers distribute effortlessly in the middle ear, whereas an additional ventilation hole is advantageous when applying thermosensitive hydrogels. The round window is coated with required volumes between 150 and 200 μl, irrespective of the injection position. Required volumes to also coat the stapedial footplate ranged from 310 to 440 μl. Use of the Whitacre-type needle reduced backflow to the ear canal and enabled longer tympanic membrane visibility when no additional ventilation hole was placed. CONCLUSION Intratympanic injection is a safe and reliable method for the application of thermosensitive hydrogels. The round window niche is readily filled regardless of the injected formulation and injection position. Although fluid drug carriers distribute effortlessly in the middle ear, the placement of an additional ventilation hole might facilitate the application of viscous hydrogels.

Abstract
OBJECTIVES The aim of this review is to assess the methodological quality of guidelines for the management of vertigo and dizziness and to compare their recommendations, with specific focus on neuroimaging. DATABASES REVIEWED MEDLINE, EMBASE, National Guideline Clearinghouse, and National Institute for Health and Clinical Excellence database. METHODS In March 2022, a systematic search was performed to find practice guidelines of management of vertigo and dizziness. The evaluation of guidelines quality was performed independently by four authors using the AGREE II tool. We excluded from the results those guidelines that were not primarily focused on vertigo and dizziness, such as national/international guidelines in which vertigo and dizziness were only briefly mentioned. RESULTS Our strategy of literature search identified 161 studies, and 18 guidelines were selected for the appraisal. Only five guidelines reached the acceptance level in the overall result (at least 60%), with three of them reaching the highest scores (at least 80%). The highest scores were found in Domain 6 "Editorial Independence," Domain 1 "Scope and purpose," and Domain 4 "Clarity of presentation" (median value = 66%, 62%, and 61%, respectively). The remaining domains showed a low level of quality: Domain 2 "Stakeholder Involvement," Domain 3 "Rigor of development," and Domain 5 "Applicability" had median values of 27%, 27%, and 22%, respectively. The quality of these guidelines was very low, because of low involvement of multidisciplinary teams in writing guidelines recommendations. CONCLUSION Considering all guidelines, only three had a "high" overall score, whereas 13 of 18 (72%) of them were rated as of "low" quality. Future guidelines might take this into account to improve clinical applicability.

Abstract
PURPOSE The present study aimed to investigate the clinical features of patients with direction-changing spontaneous nystagmus (DCSN) and gain insight into its underlying mechanisms. METHODS Medical records and vestibular function test results collected in our dizziness clinic between February 2013 and February 2020 were retrospectively reviewed. Spontaneous nystagmus was recorded while sitting upright using videonystagmography for 2 min to confirm the spontaneous changes in nystagmus direction. Causative disease diagnoses were based on the patients' clinical history, audiometry results, vestibular function tests, and imaging studies. RESULTS Of 4786 patients, DCSN was observed in 41 (0.86%). Causative disease diagnoses included vestibular neuritis (n = 9), lateral semicircular canal cupulopathy (n = 9), cerebellopontine angle tumor (n = 8), vestibular paroxysmia (n = 2), vestibular migraine (n = 2), vestibular nucleus infarction (n = 1), sudden sensorineural hearing loss with vertigo (n = 2), Meniere's disease (n = 2), Ramsay Hunt syndrome (n = 1), labyrinthine fistula due to middle ear cholesteatoma (n = 1), lateral semicircular canal dysplasia (n = 1), post tympanomastoidectomy dizziness (n = 1), and head trauma (n = 2). CONCLUSIONS Although the periodicity of DCSN could not be determined because of insufficiently long observation times, it was observed in various central and peripheral vestibulopathies. Careful examination of spontaneous nystagmus over a sufficient period may ensure the detection of DCSN when evaluating dizziness.

Abstract
A high rate of Meniere's disease (MD) in patients with osteoporosis has been suggested. This research intended to estimate the bidirectional association of MD with osteoporosis. The ≥40-year-old population in the Korean National Health Insurance Service-Health Screening Cohort 2002-2019 was examined. In study I, 9529 patients with MD and 38,116 control I participants were analyzed for a previous history of osteoporosis. In study II, 65,858 patients with osteoporosis and 65,858 control II participants were analyzed for a previous history of MD. Stratified Cox proportional hazard models were applied to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) of MD for osteoporosis in study I and of osteoporosis for MD in study II. The rate of a prior history of osteoporosis was 13.3% for the MD group and 11.3% for the control I group. The patients with MD had a 1.12 times higher HR for previous osteoporosis (95% CI = 1.04-1.20). In study II, the rate or a prior history of MD was 3.7% for patients with osteoporosis and 2.0% for the control II group. The patients with osteoporosis had a 1.50 times higher HR for previous MD (95% CI = 1.40-1.61). Most subgroups according to age, sex, and comorbid conditions demonstrated consistent bidirectional associations between MD and osteoporosis. Adult patients with MD had a greater risk of osteoporosis. In addition, adult patients with osteoporosis also showed a higher risk of MD.

Abstract
OBJECTIVES To determine the prevalence of polypharmacy in patients presenting with dizziness to a tertiary neurotology clinic and analyze the association between polypharmacy and clinical characteristics. DESIGN Retrospective, cross-sectional review. Demographics, symptoms, diagnoses, medications, audiometry, dizziness handicap index (DHI) scores, and cognitive failure questionnaire (CFQ) scores were extracted from charts of patients seen as new patients from September 1, 2019, to March 31, 2020, with a primary complaint of dizziness. RESULTS A total of 382 patients were included. More than two-thirds of the patients (n = 265, 69.4%) met criteria for polypharmacy (≥5 medications), of which most (n = 249, 94.0%) were prescribed a potentially ototoxic drug. Approximately 10% of patients were taking five or more ototoxic medications (oto-polypharmacy). Polypharmacy was correlated to age and was more common for patients with diabetes, hypertension, other cardiovascular comorbidities, and depression (odds ratio [OR], 3.73-6.67; p < 0.05). Polypharmacy was twice as likely in patients with mild to moderate hearing loss (OR 2.02 [1.24-3.29] and OR 2.13 [1.06-4.27], respectively; p < 0.05) and ~1.5× more likely in patients who had moderate to severe DHI scores (OR 1.65 [1.05-2.59] and OR 1.63 [1.00-2.65], respectively; p < 0.05). Patients with polypharmacy also had higher CFQ scores compared to those without polypharmacy (CFQ 32.5 [19.0-48.0] versus CFQ 25.0 [13.0-40.0]; p = 0.002. Oto-polypharmacy was more common for patients with lightheadedness as a dizziness descriptor (OR 3.16 [1.56-6.41]; p < 0.01). However, oto-polypharmacy was only more common for patients with mild to moderate hearing loss (OR 2.69 [1.33-5.45] and OR 2.86 [1.31-6.20], respectively; p < 0.01) and severe DHI scores (2.31 [1.12-4.77], p = 0.02). CONCLUSIONS The prevalence of polypharmacy in patients with vestibular disorders is high. Some of the medications that patients are on are also potentially ototoxic at variable degrees. Polypharmacy is more common when lightheadedness is one of the dizziness descriptors and seems to be associated with worse scores on patient-reported outcome measures (DHI, CFQ). Medication reconciliation and multidisciplinary involvement could help to better address polypharmacy in this patient population. However, further investigation is needed to elucidate polypharmacy's role in symptom presentation, vestibular testing results, and therapeutic strategies.

Abstract
Corticosteroids, oral or transtympanic, remain the mainstay for inner ear diseases characterized by hearing fluctuation or sudden changes in hearing, including sudden sensorineural hearing loss (SSNHL), Meniere's disease (MD), and autoimmune inner ear disease (AIED). Despite their use across these diseases, the rate of complete recovery remains low, and results across the literature demonstrates significant heterogeneity with respect to the effect of corticosteroids, suggesting a need to identify more efficacious treatment options. Previously, our group has cross-referenced steroid-responsive genes in the cochlea with published single-cell and single-nucleus transcriptome datasets to demonstrate that steroid-responsive differentially regulated genes are expressed in spiral ganglion neurons (SGN) and stria vascularis (SV) cell types. These differentially regulated genes represent potential druggable gene targets. We utilized multiple gene target databases (DrugBank, Pharos, and LINCS) to identify orally administered, FDA approved medications that potentially target these genes. We identified 42 candidate drugs that have been shown to interact with these genes, with an emphasis on safety profile, and tolerability. This study utilizes multiple databases to identify drugs that can target a number of druggable genes in otologic disorders that are commonly treated with steroids, providing a basis for establishing novel repurposing treatment trials.

Abstract
OBJECTIVE To perform a matched cohort study to assess whether patients with Meniere's Disease (MD) require more intensive auditory rehabilitation following cochlear implantation (CI) and identify factors that may affect outcomes in patients with MD. METHODS A retrospective case review was performed. MD and control patients were matched for age, biological sex, implant manufacturer and electrode design. Outcomes measured were speech scores, number of visits to audiology department following switch-on, and post-operative active MD. RESULTS Forty consecutive implanted MD patients were identified between May 1993 and May 2019. Patients with active MD following CI required significantly more visits to the audiology department compared to controls (P < 0.01) and patients who had inactive MD post-operatively (P < 0.01). However, in MD patients, active MD was less likely following CI (P = 0.03). In patients who continued to experience active MD post-operatively, further medical and surgical ablative intervention was required to control ongoing Meniere's attacks. CONCLUSION We present the largest case series of performance outcomes in CI patients with MD. Although speech outcomes in MD patients are comparable to controls, patients with active MD pre-operatively are more likely to experience variation in CI performance requiring a prolonged period of auditory rehabilitation compared to inactive preoperative MD.

Abstract
Importance Understanding of the economic burden of recurrent vestibular causes of vertigo and areas contributing to the cost is needed. Objective To analyze and identify the factors contributing to the direct medical costs associated with Ménière disease (MD), vestibular migraine (VM), and benign paroxysmal positional vertigo (BPPV). Design, Setting, and Participants This economic evaluation used MarketScan Commercial Database claims data from 2018 to identify the non-Medicare patient population with the diagnoses of MD, VM, or BPPV. Data were analyzed January 1 to December 31, 2018. Main Outcomes and Measures The total direct medical costs associated with MD, VM, and BPPV. Results A total of 53 210 patients (mean [SD] age, 47.8 [11.8] years; 67.6% female) were included in this study, with 34 738 normal comparisons. There were 5783 (10.9%) patients with MD, 3526 (6.6%) patients with VM, and 43 901 (82.5%) patients with BPPV in the data set. Mean age and sex were different across the different vestibular disorders. Across the different groups, patients with no comorbidities or with a Charlson Comorbidity Index score of zero ranged from 98.4% to 98.8%. Around 5% of patients were hospitalized with inpatient stay lasting between 4.6 and 5.2 days. After adjusting for age, sex, and comorbidities, there were large differences in mean adjusted annual payments/direct costs across the different groups (MD, $9579; VM, $11 371; and BPPV, $8247). This equated to a total incremental estimated cost of $60 billion compared with the normal population. The number of outpatient brain magnetic resonance imaging or computed tomography scans per patient ranged anywhere from 1 to 20, while the number of inpatient brain magnetic resonance imaging or computed tomography scans per patient ranged anywhere from 1 to 6. A heat map of the total cost expenditure indicated that the costs were concentrated around the Midwest, Lake Michigan, and the East Coast. Conclusions and Relevance In this economic evaluation, the 3 most common causes of recurrent vertigo-MD, VM, and BPPV-had considerable medical costs associated with them. Extraneous imaging orders and vestibular testing are factors to consider for cost reduction. However, further research and widespread education is needed to optimize the diagnosis, treatment, and care of patients presenting with vestibular disorders or dizziness.

Elevated G-CSF, IL8, and HGF in patients with definite Meniere's disease may indicate the role of NET formation in triggering autoimmunity and autoinflammation. Sci Rep 2022; 12:16309.

Abstract
The etiology and mechanism causing Meniere’s disease (MD) are not understood. The present study investigated the possible molecular mechanism of autoimmunity and autoinflammation associated with MD. Thirty-eight patients with definite MD and 39 normal volunteers were recruited, and 48 human cytokines/chemokines were quantified. In patients with MD pure tone audiograms, tympanograms and standard blood tests were performed. The mean hearing loss in the worse ear was 44.1 dB nHL. Compared to the referents, the concentrations of TNFα, IL1α, IL8, CTACK, MIP1α, MIP1β, G-CSF, and HGF in the sera of patients with MD were significantly elevated, while those of TRAIL and PDGFBB were significantly decreased. The area under the receiver operating characteristic curve (AUC) showed that G-CSF, MIP1α, and IL8 were above 0.8 and could be used to diagnose MD (p < 0.01), and the AUCs of CTACK and HGF were above 0.7 and acceptable to discriminate the MD group from the control group (p < 0.01). The revised AUCs (1 − AUC) of TRAIL and PDGFBB were above 0.7 and could also be used in the diagnosis of MD (p < 0.01). The linear regression showed significant correlations between MIP1α and GCSF, between IL2Rα and GCSF, between IL8 and HGF, between MIP1α and IL8, and between SCF and CTACK; there was a marginal linear association between IP10 and MIP1α. Linear regression also showed that there were significant age-related correlations of CTACK and MIG expression in the MD group (p < 0.01, ANOVA) but not in the control group. We hypothesize that G-CSF, IL8, and HGF, which are involved in the development of neutrophil extracellular traps (NETs) and through various mechanisms influence the functions of macrophages, lymphocytes, and dendritic cells, among others, are key players in the development of EH and MD and could be useful in elucidating the pathophysiological mechanisms leading to MD. Biomarkers identified in the present study may suggest that both autoimmune and autoinflammatory mechanisms are involved in MD. In the future, it will be valuable to develop a cost-effective method to detect G-CSF, IL8, HGF, CTACK, MIP1α, TRAIL, and PDGFBB in the serum of patient that have diagnostic relevance.

Abstract
BACKGROUND Delayed endolymphatic hydrops (DEH) is a rare disease, and the actual number of patients in Japan remains unknown. OBJECTIVE To investigate the number and prevalence of patients with DEH in Japan. METHODS In total, 781 departments of otolaryngology in Japan were selected for survey by stratified random sampling according to the total number of hospital beds. We sent questionnaires to the target departments and collected data regarding the number of patients with DEH who visited those departments in 2019. RESULTS The overall response rate was 68.0% (531 departments). The estimate number of patients with DEH in Japan was 962, and the prevalence was calculated to be 0.8 per 100,000 population. CONCLUSION Patients with DEH were extremely rare in Japan. SIGNIFICANCE This may be the first nationwide epidemiological study on the number and prevalence of patients with DEH in Japan or in the world.

Eur J Pharm Sci 2022; 178:106291. [PMID: 36058499 DOI: 10.1016/j.ejps.2022.106291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 07/12/2022] [Accepted: 08/31/2022] [Indexed: 11/27/2022]
Abstract
The safety and efficacy of intratympanic (IT) histamine (HIS) injection as an adjuvant to increase the inner ear penetration of dexamethasone (DEX) was investigated in this study. IT injections of DEX-only, 1% HIS+DEX and 4% HIS+DEX were performed in mice with noise-induced hearing loss. An inflammatory reaction in the middle ear was observed only in the 4% HIS+DEX group although no serious cytotoxic effects on the organ of Corti (OC) were observed at that concentration. Compared with the DEX-only group, the perilymphatic concentration of DEX was approximately two times higher in the 1% HIS+DEX group and approximately five times higher in the 4% HIS+DEX group. The expression of the DEX receptor in the cochlea was significantly increased in the 4%-HIS+DEX group. HIS appeared to induce transient damage the microstructure of the RWM with recovery observed within 3 weeks. The 1% and 4% HIS + DEX groups showed a significant recovery of the OC compared with the control group and they also achieved significantly better hearing restoration at 8 kHz in the DPOAE hearing test (P < .05) when compared to the DEX-only group. IT HIS temporarily disrupts the structure of the RWM and middle ear mucosa and significantly enhances the inner ear penetration of DEX. Therefore, IT HIS injection could be a simple and effective adjuvant therapy to increase perilymph concentration of DEX and achieve OC recovery after cochlear damage.

Abstract
Objective:To construct a prediction model for Ménière's disease based on neural network and evaluate its prediction ability. Methods:Sixty-four patients with Ménière's disease underwent gadolinium enhanced magnetic resonance imaging of inner ear which showed endolymphatic hydrops. Meanwhile, 40 healthy adults were enrolled as controls. The database of wideband tympanometry of patients and control subjects was analyzed, and the neural network model was established by MATLAB 2021a software. The prediction ability of the model was evaluated by accuracy, positive predictive value, negative predictive value, the Youden index, sensitivity, specificity, receiver operating characteristic curve and area under curve (AUC). Results:A feedforward network model was built with a single hidden layer to predict Ménière's disease with wideband tympanometry. There were 104 features in the input layer, 13 neuron nodes in the hidden layer and 1 output neuron in the output layer. The accuracy of the model was 83.2%, the positive predictive value was 80.7%, the negative predictive value was 84.3%, the sensitivity was 76.5%, the specificity was 83.7%, the Youden index was 0.602, and the AUC was 0.855. Conclusion:Based on neural network, the prediction model of Ménière's disease with high accuracy was constructed according to the results of wideband tympanometry, which provided reference for the diagnose of Ménière's disease.

Abstract
Background Several methods are used for hearing loss screening; however, their benefits are uncertain. In this study, we aimed to determine the predictive factors of acute sensorineural hearing loss for clinical application by primary care doctors. Methods This retrospective, cross-sectional study included 365 patients with acute sensorineural hearing loss without prior therapy. The patients’ clinical data, demographic information, and medical histories were obtained, and they were asked about comorbidities. In addition, we assessed lifestyle factors such as stress level, alcohol consumption, marital status, and socioeconomic level. Logistic regression analysis was performed to investigate the diagnostic predictive ability of the selected factors associated with acute sensorineural hearing loss. The hearing levels of all patients were evaluated using pure tone audiometry. Results We identified significant predictive factors for acute sensorineural hearing loss. The absence of hyperacusis was a predictive factor for sudden sensorineural hearing loss. Younger age, female sex, and marital status were predictive factors for acute low-tone hearing loss. High body mass index, high socioeconomic level, low alcohol consumption, high stress level, hyperacusis, and vertigo/dizziness were predictive factors for Ménière’s disease. High body mass index and ear fullness were predictive factors for perilymph fistula. Low stress level was a predictive factor for acoustic tumours. Conclusions Our findings can be used to distinguish between the types of acute sensorineural hearing loss. Symptoms, physical status, and lifestyle factors identified during this study are useful markers for predicting acute sensorineural hearing loss occurrence.

Abstract
A few prior researchers presumed the impacts of smoking and alcohol on the risk of Meniere’s disease (MD). This study investigated the relationship between smoking, alcohol consumption, and obesity with Meniere’s disease in an adult population. The ≥40-year-old population in the Korean National Health Insurance Service-Health Screening Cohort 2002−2019 was analyzed. A total of 15,208 patients with MD were matched with 499,658 comparison participants. The current smoking, alcohol consumption, and past medical histories were collected. Body mass index (BMI) was grouped into underweight, normal, overweight, obese I, and obese II. The odds of histories of smoking and alcohol consumption and the BMI group for MD were analyzed using conditional logistic regression analysis. These associations were further analyzed in subgroups of age, sex, smoking, alcohol consumption, and BMI. In the overall adult population, smoking and alcohol consumption did not show an association with MD. Being underweight was linked with lower odds for MD (adjusted OR [aOR] = 0.80, 95% CI = 0.68−0.93, p = 0.004). In the male group, smoking was positively associated with MD (aOR = 1.08, 95% CI = 1.00−1.17, p = 0.043), while alcohol consumption was negatively related to MD (aOR = 0.87, 95% CI = 0.81−0.94, p < 0.001). Being underweight was related to a lower risk of MD. In adult men, smoking was predicted to increase, while alcohol consumption was predicted to decrease the risk of MD.

Abstract
Vestibular assessment tests such as the video head impulse test (vHIT) for the horizontal semicircular canal, and caloric test (Cal), both evaluate horizontal canal function. One would assume that the outcomes for these tests should lead to concordant results, yet several studies have suggested that dissociation can occur in certain pathological conditions. As this topic remains inconclusive, this review aims to analyze the scientific evidence regarding the patterns of hypofunction observed in vHIT and Cal in different otoneurological diseases. A comprehensive review of the literature regarding dissociation between these tests in common neurotological diseases was carried out. Articles were analyzed when data for vHIT and Cal were described in a way that it was possible to calculate discordance rates; both retrospective and prospective studies were analyzed. In this review, the discordance rates were as follows: 56% in Ménière’s disease, 51.5% in vestibular migraine, 37.2% in vestibular schwannoma, and 20.8% in vestibular neuritis. These results highlight the benefit of using both Cal and vHIT, and that they are complementary tests.

Abstract
Dizziness is one of the most common symptoms encountered by physicians daily. It is divided into four categories: vertigo, disequilibrium, presyncope, and psychogenic dizziness. It is essential to distinguish these four symptoms because the causes, prognosis, and treatment differ. Vertigo constitutes a disease of the central or peripheral nervous system. Central origin vertigo may be a life-threatening situation and must be detected as soon as possible because it includes diseases such as stroke, hemorrhage, tumors, and multiple sclerosis. Peripheral origin vertigo includes benign diseases, which may be fully treatable such as vestibular migraine, benign paroxysmal positional vertigo, vestibular neuritis, Ménière’s disease, and cervical vertigo. The HINTS (head impulse, nystagmus, test of skew) examination is essential to distinguish central from peripheral causes. A detailed history including the duration of vertigo (episodic or continuous), its trigger, and a clinical examination step by step following the appropriate protocol could help to make a definite and accurate diagnosis and treatment. Due to a lack of expertise in dizziness and inappropriate treatment, many patients are admitted to dizziness clinics with long-standing dizziness. A holistic treatment combining medications, vestibular rehabilitation, physiotherapy, and psychotherapy should be initiated to improve the quality of life of these patients. So, this review aims to recommend a clinical protocol for approaching a dizzy patient with vertigo and to present in detail the epidemiology, pathophysiology, symptoms, diagnosis, and contemporary treatments of all causes of vertigo.

Abstract
Present study aimed to find if multiple audio-vestibular tests can be used to improve in diagnosing Meniere's disease. The study compares the results of four test procedures of glycerol test, Electrocochleography (ECochG), cervical Vestibular Evoked Myogenic Potential (c-VEMP) and ocular Vestibular Evoked Myogenic Potential (o-VEMP) individually and also together to see whether the diagnosis of Meniere's disease can be improved. Experimental group consist of 16 participants (32 ears) diagnosed with Meniere's disease as per American Academy of Otolaryngology (AAO) -Head and Neck Foundation (2020) guidelines. Control group consist of 16 participants with compliant of only vertigo participated in the study. Participants in both group underwent glycerol test, Electrocochleography (ECochG), cervical Vestibular Evoked Myogenic Potential (c-VEMP) and ocular Vestibular Evoked Myogenic Potential (o-VEMP). Glycerol test showed a 38% positive rate for the presence of Meniere's disease. ECochG indicated the presence of endolymphatic hydrops in 62% of the participants. Abnormal finding in c-VEMP and o-VEMP was seen in 31% and 56% of the participants respectively. The combination of two tests such as ECochG and o-VEMP has increased the positive rate upto 87%. Adding one more test of c-VEMP or combining all four audiovestibular tests had a positive rate of 94% only. The present study indicated ECochG is a more sensitive tool in the diagnosis of Meniere disease followed by o-VEMP. Thus, the present study indicated that combination ECochG and o-VEMP could be used to find the presence of Meniere's disease successfully.

Abstract
Importance Overuse of costly neuroimaging technology is associated with low-value care for the prevalent symptom of dizziness. Although quality improvement initiatives have focused on the overuse of computed tomography (CT) scans in emergency departments (EDs), most patients with dizziness present to outpatient clinics. To inform practice and policy, a comprehensive understanding of the uses and costs of neuroimaging across settings and episodes of care is needed. Objective To characterize neuroimaging use, timing, and spending as well as factors associated with imaging acquisition within 6 months of presentation for dizziness in outpatient vs ED settings. Design, Setting, and Participants This cross-sectional study of commercial and Medicare Advantage claims for 805 454 adults (≥18 years of age) with new diagnoses of dizziness was conducted from January 1, 2006, through December 31, 2015. Data were analyzed from October 1, 2020, to September 30, 2021. Main Outcomes and Measures Use of neuroimaging (CT scan, magnetic resonance imaging [MRI], angiography, and ultrasonography) and total spending on neuroimaging were measured. Kaplan-Meier analysis was performed. The associations of neuroimaging with setting, sociodemographic characteristics, and clinicians were estimated with multivariable analyses. Results A total of 805 454 individuals with dizziness (502 055 women [62%]; median age, 52 years [range, 18-87 years]) were included in this study; 156 969 (20%) underwent neuroimaging within 6 months of presentation (65 738 of 185 338 [36%] presented to EDs and 91 231 of 620 116 [15%] presented to outpatient clinics). The median time to neuroimaging was 0 days (95% CI, 0-2 days) after ED presentation and 10 days (95% CI, 9-10 days) after outpatient presentation. Neuroimaging was independently associated with advanced age, comorbidity, race and ethnicity, ED presentation, and outpatient clinician specialty. Across sites, a head CT scan was the most used test on presentation date (92% of tests [46 852 of 51 022]). Within 6 months of presentation, a head CT scan was the most used test (47% of all tests [177 949 of 376 149]), followed by brain MRI (25% [93 130 of 376 149]), cerebrovascular ultrasonography (15% [56 175 of 376 149]), and magnetic resonance angiography (9% [34 026 of 376 149]). Of $88 646 047.03 in total neuroimaging spending, MRI accounted for 70% ($61 730 251.95), CT scans for 19% ($16 910 506.24), and ultrasonography for 11% ($10 005 288.84). Per-test median spending ranged from $68.97 (CT scan of the head) to $319.63 (MRI of the brain) among commercially insured individuals and $43.21 (CT scan of the head) to $362.02 (MRI of the orbit, face, and neck) among Medicare Advantage beneficiaries. Conclusions and Relevance The findings of this cross-sectional study suggest that use of neuroimaging for dizziness is prevalent across settings. Interventions to optimize the use of neuroimaging must occur early in the patient care journey to discourage guideline-discordant use of CT scans, advocate for judicious MRI use (particularly in ambulatory settings), and account for the effects of price transparency.

Importance A connection between Meniere disease (MD) and migraine has been proposed, but the temporal association remains unknown. Objective To examine the bidirectional association of MD with migraine. Design, Setting, and Participants This case-control study included participants 40 years or older from the Korean National Health Insurance Service Health Screening Cohort from 2002 to 2015. Main Outcomes and Measures A total of 6919 patients with MD were matched with 27 676 control participants without MD for age, sex, income, region of residence, and index date. The incidence of migraine was analyzed in the MD and matched groups using a stratified Cox proportional hazard regression model. In addition, 35 889 patients with migraine were matched with 71 778 control participants without migraine. The incidence of MD was analyzed using a stratified Cox proportional hazard regression model. Results Of 142 262 total participants, 94 611 (66.5%) were women. Migraine occurred in 695 of 6919 patients with MD (10.0%) and 970 of 27 676 matched control participants (3.5%). The MD group demonstrated a 2.22-fold higher risk of migraine than the matched control group (95% CI, 1.99-2.49). Meniere disease was present in 1098 of 35 889 patients with migraine (3.1%) and 781 of 71 778 matched control participants (1.1%). The migraine group had a 1.95-fold higher risk of MD than the matched control group (95% CI, 1.77-2.15). Conclusions and Relevance The results of this case-control study suggest that patients with MD had a greater risk of migraine occurrence. Furthermore, patients with migraine had a higher risk of MD. Based on the bidirectional association, therapeutics for migraine could potentially be applied to MD and vice versa.

Consensus on intratympanic drug delivery for Menière's disease. Eur Arch Otorhinolaryngol 2022; 279:3795-3799.

Abstract
Purpose Intratympanic (IT) drug delivery receives attention due to its effectivity in treatment for Menière’s disease (MD). Due to the release of the consensuses and new evidence on IT drug delivery for MD have been published, the review with a view to supplementing the details of IT treatment of MD is indispensable. Methods The literatures on IT injection for MD treatment over the last two decades are retrieved, International consensus (ICON) on treatment of Menière’s disease (2018), Clinical Practice Guideline (2020) and European Position statement on Diagnosis and Treatment of Meniere’s Disease (2018) are taken into account for reference, and follow advice from experts from Europe, USA and China. Results Experts agree on the following: (1) The effectiveness of IT methylprednisolone (ITM) on vertigo control seems to be somewhat better than that of IT dexamethasone (ITD), and ITM can restore hearing in some cases. (2) Due to the ototoxicity of aminoglycosides, the application of intratympanic gentamicin (ITG) in MD patients with good hearing is conservative. However, some studies suggest that ITG with low doses has no significant effect on hearing, which needs to be further proved by clinical studies with high levels of evidence. (3) Currently, generally accepted treatment endpoint of ITG is no vertigo attack in a 12-month period or a vestibular loss in objective tests in the affected ear. Conclusion More studies with high level of evidence are needed to evaluate the drug type, efficacy, and therapeutic endpoint of IT therapy for MD.

Abstract
Vertigo in children is a challenging topic. The lack of dedicated trials, guidelines and papers causes inhomogeneity in the treatment of vertigo in children. Meniere’s disease, migraine equivalents, vestibular neuritis, paroxysmal positional benign vertigo (BPPV), persistent postural-perceptual dizziness (PPPD) and motion sickness may affect children with various degrees of incidence and clinical severity compared to adults. Several drugs are proposed for the management of these conditions, even if their use is subordinated to the child’s age. In this review, we summarize the existing evidence related to the use of drugs for this clinical condition in children as a start point for new trials, stating the urgent need for international guidelines.

A Perspective for Ménière’s Disease: In Silico Investigations of Dexamethasone as a Direct Modulator of AQP2. Biomolecules 2022; 12:biom12040511. [PMID: 35454100 PMCID: PMC9028334 DOI: 10.3390/biom12040511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 03/21/2022] [Accepted: 03/24/2022] [Indexed: 12/04/2022] Open
Abstract
Ménière’s disease is a chronic illness characterized by intermittent episodes of vertigo associated with fluctuating sensorineural hearing loss, tinnitus and aural pressure. This pathology strongly correlates with a dilatation of the fluid compartment of the endolymph, so-called hydrops. Dexamethasone is one of the therapeutic approaches recommended when conventional antivertigo treatments have failed. Several mechanisms of actions have been hypothesized for the mode of action of dexamethasone, such as the anti-inflammatory effect or as a regulator of inner ear water homeostasis. However, none of them have been experimentally confirmed so far. Aquaporins (AQPs) are transmembrane water channels and are hence central in the regulation of transcellular water fluxes. In the present study, we investigated the hypothesis that dexamethasone could impact water fluxes in the inner ear by targeting AQP2. We addressed this question through molecular dynamics simulations approaches and managed to demonstrate a direct interaction between AQP2 and dexamethasone and its significant impact on the channel water permeability. Through compartmentalization of sodium and potassium ions, a significant effect of Na+ upon AQP2 water permeability was highlighted as well. The molecular mechanisms involved in dexamethasone binding and in its regulatory action upon AQP2 function are described.

Abstract
Objective:To evaluate the efficacy of vestibular rehabilitation in patients with anterior peripheral vertigo and analyze its influencing factors. Methods:From January 2018 to June 2021, 153 cases with peripheral vertigo diseases(including 47 cases of benign positional paroxysmal vertigo, 38 cases of Meniere's disease, 26 cases of sudden deafness with vertigo, 23 cases of vestibular migraine and 19 cases of vestibular neuritis) were enrolled. One hundred and three cases were treated with vestibular rehabilitation combined with drugs, and 50 cases only treated with drugs were used as controls. Self-rating scale and vertigo disorder scale were evaluated at the beginning of treatment, 4 weeks and 8 weeks, respectively. The curative effects of the two groups were tested by t-test, and the independent risk factors affecting the curative effects were analyzed by multiple linear regression. Results:There was no difference in clinical data, self-assessment scale and vertigo disorder scale between the two groups(P>0.05). At 4 and 8 weeks, the scores of self-assessment scale and vertigo disorder scale in the experimental group were better than those in the control group(all P<0.01), and the curative effect at 8 weeks was better than that at 4 weeks, especially the decrease of emotional score during walking and the proportion of severe vertigo disability(all P<0.01). The scores of self-rating scale and vertigo disorder scale of the cases with benign positional paroxysmal vertigo and vestibular neuritis were better than Meniere's disease, vestibular migraine and sudden deafness with vertigo(P<0.05). Headache(P<0.05) and severe vertigo disorder before intervention(P<0.01) were independent risk factors affecting the efficacy of vestibular rehabilitation. Conclusion:Vestibular rehabilitation combined with anti-vertigo drugs in the treatment of vestibular peripheral vertigo is better than that of only using drugs, especially in improving the degree of emotional disorder and vertigo disability. It is more suitable for benign positional paroxysmal vertigo and vestibular neuritis, while the effect of combined headache or severe vertigo is relatively poor.

Dexamethasone does not affect endolymphatic hydrops (EH) in patients with Meniere’s disease within 24 h, and intratympanic administration of gadolinium plus dexamethasone simplifies high-quality imaging of EH using a novel protocol of 7 minutes. J Otol 2022; 17:164-174. [PMID: 35847578 PMCID: PMC9270566 DOI: 10.1016/j.joto.2022.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 02/23/2022] [Accepted: 02/28/2022] [Indexed: 11/28/2022] Open
Abstract
Background Intratympanic administration of gadolinium chelate allows for a better visualization of endolymphatic hydrops (EH) using MRI than intravenous injection and was recently further improved to facilitate high-quality imaging of EH in 7 min. The aim of the present study was to simplify the intratympanic administration protocol by mixing gadolinium chelate with therapeutic dexamethasone and to evaluate the effects of this mixture on the visualization of EH in MRI. Materials and methods In an in vitro study, the potential impact of gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) on the stability of dexamethasone was evaluated by analyzing dynamic changes in dexamethasone with high-performance liquid chromatography (HPLC) after mixing with Gd-DTPA. Ten patients with definite Meniere's disease (MD) were recruited to study the potential interference of dexamethasone on MRI visualization of EH, and 49 patients with MD were recruited to evaluate the effect of intratympanic injection of Gd-DTPA mixed with dexamethasone on MRI of EH using a 3T MR machine and a novel heavily T2-weighted 3-dimensional fluid-attenuated inversion recovery reconstructed using a magnitude plus zero-filled interpolation (hT2FLAIR-MZFI) sequence. Results The retention times and peak area of dexamethasone in HPLC were not modified by the addition of Gd-DTPA. EH grading in the cochlea and vestibule was not influenced in any ear by intratympanic injection of dexamethasone. Excellent inner ear images were obtained from all patients, and EHs with various grades were displayed. There were significant correlations between diagnosis and cochlear EH (p < 0.01, Spearman's Rho), between diagnosis and vestibular EH (p < 0.01, Spearman's Rho), and between cochlear and vestibular EH (p < 0.01, Spearman's Rho). The distribution of Gd-DTPA plus dexamethasone negatively correlated with the grade of vestibular EH. Injury of the endolymph-perilymph barrier was detected in one cochlea and three vestibules of 59 inner ears with MD. Conclusions Intratympanic administration of Gd-DTPA plus dexamethasone yielded high-quality MRI images of EH in patients with MD using a novel 7-min protocol and simplified the clinical application. Intratympanic administration of Gd-DTPA plus dexamethasone might be used to test its therapeutic effect in future work. Level of evidence 3.

Abstract
Objectives The underlying etiology of Meniere's disease (MD) is not completely clear, but the precipitated triggers may alter the circadian clock in patients with MD. This study aims to survey the expression of circadian clock genes in peripheral blood (PB) leukocytes of MD patients. Methods We investigated the expression of nine circadian clock genes in the PB leukocytes of patients with MD and normal controls using real‐time quantitative reverse transcriptase‐polymerase chain reaction (qRT‐PCR). Results We observed significantly lower expression of PER1 gene and higher expression of CLOCK gene in MD patients than those in normal controls (p < 0.05). PER1 did not associate with the degree of dizziness handicap in the patients with MD, but a lower expression of PER1 was significantly correlated with higher pure tone average (PTA) and speech reception threshold of the affected ear (p < 0.05). Patients with PTA > 30 dB had significantly lower PER1 expression than those with PTA ≤30 dB in the affected ear (p < 0.05). Our qRT‐PCR result was validated by fewer positively stained leukocytes for PER1 protein in the MD patients using the immunocytochemical study. Conclusion Our study implies the alteration of the circadian clock in patients with MD. In particular, the downregulation of PER1 correlated with the degree of hearing loss in the affected ear. PER1 in PB leukocytes may be a potential marker for the progression of hearing loss in MD.

Abstract
Reducing the amounts consumed of organic solvents while keeping good chromatographic performance has been a significant step towards the greening of analytical methodologies. When sodium dodecyl sulfate (SDS) and Brij-35 surfactants are combined in a mobile phase, they can be used as a green alternative to organic modifiers. Surfactants have numerous advantages, including low cost and toxicity, safe environmental disposal, and unique selectivity, in addition to high solubilization capabilities. In this research, two highly selective chromatographic methods were adopted for the determination of betahistine (BHS) in the presence of its pharmacopeial impurity 2-(2-hydroxyethyl)pyridine (HEP). A solvent-free HPLC method was validated, in which the mixture was separated using a C18 column (3.5 µm, 75.0 × 4.6 mm) and a mobile phase composed of 0.01 M Brij-35, 0.12 M SDS, and 0.02 M disodium hydrogen phosphate adjusted to a pH of 5.5 using phosphoric acid. The flow rate was 1.5 mL min−1 and the resolved peaks were detected at 260 nm. Another HPTLC-densitometric method was validated using HPTLC aluminum plates coated with silica gel 60 F254 as the stationary phase and a developing system consisting of methylene chloride/methanol/ethyl acetate/ammonia (at a ratio of 5:2:2:0.2 by volume); the separated bands were scanned at 260 nm.

Abstract
BackgroundMeniere's disease (MD) is an inner ear disorder, characterized by recurrent attacks of vertigo, low-frequency sensorineural hearing loss, tinnitus, and aural fullness. Endolymphatic sac surgery is an effective treatment to control vertigo attacks but without causing a hearing loss for intractable MD. However, the methods and effects of endolymphatic sac surgery have been controversial for many years, and the relationship between the vertigo control rates of different endolymphatic sac surgery methods is not well-documented.ObjectivesThis study compared the vertigo control rate, hearing outcome, and quality of life (QOL) among different endolymphatic sac surgery, such as local endolymphatic sac decompression (LESD), endolymphatic sac mastoid shunt (ESMS), and wide endolymphatic sac decompression (WESD).Materials and MethodsWe retrospectively analyzed the patients who underwent endolymphatic sac surgery from January 2008 to June 2019. The control rate of vertigo and QOL scores were compared after 2 years of follow-up. The QOL was scored with validation of the MD patient-oriented symptom-severity index (MDPOSI). The pure tone thresholds of all patients at pre- and postoperation were also compared.ResultsIn total, 83 MD patients with complete follow-up data were included in the study, i.e., 20 patients with LESD, 28 patients with ESMS, and 35 patients with WESD. Results showed a better vertigo control with WESD than the other groups (70% with LESD, 71.4% with ESMS, and 88.6% with WESD). The QOL was improved after surgery in all groups in which the difference was statistically significant (QOL, preoperative vs. postoperative, 38.2 vs. 10.1 with LESD, 37.8 vs. 9.6 with ESMS, and 37.6 vs. 8.3 with WESD), respectively. After endolymphatic sac surgery, the hearing was well-preserved in the three groups [pure tone averages (PTAs), dB, preoperative vs. postoperative, 41.0 ± 19.3 vs. 40.8 ± 17.9 with LESD, 39.7 ± 16.4 vs. 40.8 ± 18.2 with ESMS, and 38.5 ± 18.7 vs. 36.6 ± 19.5 with WESD].ConclusionWide endolymphatic sac decompression has a higher vertigo control rate, better improvement of QOL, and relatively higher hearing stability or improvement rate after surgery in patients with MD compared with LESD and ESMS.

Abstract
Importance Ménière disease is a rare chronic benign disorder of the inner ear with a natural history of multiple clinical phenotypes of variable severity and a tendency to burnout with time. Although multiple treatment modalities have been shown to improve the disease process-some adversely affecting cochleovestibular function-it remains uncertain whether one, several separate, or a combination of pathophysiologic mechanisms affect the disease process. A scoping review of the evidence underlying proposed pathophysiologic mechanisms of Ménière disease is needed to determine which processes are most likely to be etiopathogenic factors. Observations Of the 4602 relevant articles found through Embase, Ovid, and PubMed, 444 met inclusion criteria. The most common reported causes of Ménière disease were autoimmune or immune-mediated, genetic, or structural dysfunction of the inner ear. During the study period from inception to March 2021, etiologic theories shifted from structural dysfunction to autoimmune and genetic causes of Ménière disease. Conclusions and Relevance This scoping review found that Ménière disease is a multifactorial disease with lifelong comorbidities and loss of quality-associated life-years whose most commonly reported causes were structural dysfunction, immunologic damage, and genetic susceptibility. Recent studies have examined how autoinflammatory processes and vestibular migraine may be associated with Ménière disease. Large heterogeneity among studies may be explained by historical differences in the clinical understanding of the disease, as well as evolving intervention methodologies and practitioner expertise. Ménière disease is a multifactorial disease with lifelong comorbidities and loss of quality-associated life-years; therefore, future studies of reliable biomarkers of endolymphatic hydrops and real-time imaging are warranted to improve understanding and treatment.

Front Neurol 2022; 13:797699. [PMID: 35185763 PMCID: PMC8854354 DOI: 10.3389/fneur.2022.797699] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 01/13/2022] [Indexed: 11/13/2022] Open
Abstract
Background The clinical efficacy of triple semicircular canal occlusion (TSCO) and vestibular nerve resection (VNS) for patients with Ménière's disease has been unclear. Objective To explore changes in vestibular symptoms after TSCO and its advantages compared to the classical operation of VNS in patients with Menière's disease. Methods In total, 36 patients with Menière's disease performed TSCO or VNS at Shanghai Jiao Tong University Affiliated Sixth People's Hospital, China from May 2005 to July 2021, and all of them were enrolled in our study. Twelve of them underwent TSCO, 23 underwent VNS, and 1 had both treatments. We compared the demographic parameters, clinical symptoms, and selected test results between the two surgical methods. Ten patients each who underwent TSCO and VNS completed the follow-up. We collected and compared data pertaining to changes in vestibular symptoms. Results No significant difference in demographic parameters, clinical symptoms, or auditory or vestibular test results was detected between the two groups preoperatively. The TSCO group with vertigo as the main complaint experienced less residual paroxysmal dizziness after surgery than the VNS group (P = 0.020). Also, 57% of the patients in the VNS group had unsteadiness after surgery, while no such problems were reported in the TSCO group (P = 0.025). Conclusions Our study shows that TSCO controls vertigo in most Menière's disease patients, and also has the advantage of lower rates of postoperative paroxysmal dizziness and unsteadiness than VNS. Thus, TSCO may be an effective surgery for refractory Menière's disease.

Low-salt diet increases mRNA expression of aldosterone-regulated transporters in the intermediate portion of the endolymphatic sac. Pflugers Arch 2022; 474:505-515. [PMID: 35112133 DOI: 10.1007/s00424-021-02661-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 12/08/2021] [Accepted: 12/23/2021] [Indexed: 11/29/2022]
Abstract
The endolymphatic sac is a small sac-shaped organ at the end of the membranous labyrinth of the inner ear. The endolymphatic sac absorbs the endolymph, in which the ion balance is crucial for inner ear homeostasis. Of the three sections of the endolymphatic sac, the intermediate portion is the center of endolymph absorption, particularly sodium transport, and is thought to be regulated by aldosterone. Disorders of the endolymphatic sac may cause an excess of endolymph (endolymphatic hydrops), a histological observation in Meniere's disease. A low-salt diet is an effective treatment for Meniere's disease, and is based on the assumption that the absorption of endolymph in the endolymphatic sac abates endolymphatic hydrops through a physiological increase in aldosterone level. However, the molecular basis of endolymph absorption in each portion of the endolymphatic sac is largely unknown because of difficulties in gene expression analysis, resulting from its small size and intricate structure. The present study combined reverse transcription-quantitative polymerase chain reaction and laser capture microdissection techniques to analyze the difference of gene expression of the aldosterone-controlled epithelial Na+ channel, thiazide-sensitive Na+-Cl- cotransporter, and Na+, K+-ATPase genes in the three individual portions of the endolymphatic sac in a rat model. A low-salt diet increased the expression of aldosterone-controlled ion transporters, particularly in the intermediate portion of the endolymphatic sac. Our findings will contribute to the understanding of the physiological function of the endolymphatic sac and the pathophysiology of Meniere's disease.

Abstract
PURPOSE OF REVIEW This article reviews recent developments in Ménière's disease including etiologic, diagnostic, and therapeutic investigations that have changed the landscape for medical providers. These updates shed light onto the complex nature of Ménière's disease and generate additional means to provide optimal care to patients. RECENT FINDINGS Given the multifactorial cause of Ménière's disease, five subtypes of Ménière's disease have recently been proposed. A knowledge of these subtypes will aid in the development of an appropriate treatment algorithm. Although newer treatments have not been developed, stepwise treatment algorithms have been proposed and can improve patient care. New MRI modalities and serum testing hold promise as clinical clues and biomarkers. SUMMARY As these updated diagnostic criteria are used, Ménière's disease can be identified and treated more precisely. This will in turn allow for future randomized controlled studies to improve the quality of treatment options available. Future imaging, vestibular testing, and the potential for serum biomarkers may illuminate additional diagnostic criteria, only furthering the improvement in clinical care.

Abstract
Vestibular migraine (VM) is an increasingly recognized pathology yet remains as an underdiagnosed cause of vestibular disorders. While current diagnostic criteria are codified in the 2012 Barany Society document and included in the third edition of the international classification of headache disorders, the pathophysiology of this disorder is still elusive. The Association for Migraine Disorders hosted a multidisciplinary, international expert workshop in October 2020 and identified seven current care gaps that the scientific community needs to resolve, including a better understanding of the range of symptoms and phenotypes of VM, the lack of a diagnostic marker, a better understanding of pathophysiologic mechanisms, as well as the lack of clear recommendations for interventions (nonpharmacologic and pharmacologic) and finally, the need for specific outcome measures that will guide clinicians as well as research into the efficacy of interventions. The expert group issued several recommendations to address those areas including establishing a global VM registry, creating an improved diagnostic algorithm using available vestibular tests as well as others that are in development, conducting appropriate trials of high quality to validate current clinically available treatment and fostering collaborative efforts to elucidate the pathophysiologic mechanisms underlying VM, specifically the role of the trigemino-vascular pathways.

World Neurosurg 2022; 160:71-75. [PMID: 35032712 DOI: 10.1016/j.wneu.2022.01.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 01/06/2022] [Accepted: 01/07/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND AND OBJECTIVE Meniere's disease (MD) is an idiopathic peripheral pathology involving the acoustic apparatus. One of the most critical challenges in managing MD is intractable vertigo. In this context, the retrosigmoid vestibular neurectomy (RVN) has been described as a safe and effective technique to manage this symptom when resistant to first- and second-line treatments. In this article, the alternative treatment options, specific surgical anatomy, and relevant details to perform vestibular neurectomies for intractable MD are analyzed. METHODS Relevant neurovascular landmarks, critical surgical steps, adequate indications, and potential pitfalls of the RVN were analyzed based on an illustrative clinical case of intractable MD. RESULTS The illustrative case demonstrated how early recognition of the facial nerve and the vestibulo-cochlear plane is fundamental to performing RVN. This procedure is indicated in cases of resistant MD with pre-operative hearing integrity. Potential pitfalls of this technique are incomplete neurotomy, nerve regeneration, comorbidities in the contralateral ear, adverse anatomy, the possibility of non-otologic vertigo, and incomplete vestibular compensation. CONCLUSIONS Vestibular neurectomy represents a safe and effective technique in managing intractable MD resistant to medical treatment, allowing symptom control and hearing preservation. Nevertheless, detailed knowledge of surgical anatomy, as well as possible pitfalls, is of paramount importance to achieve a good outcome.

Abstract
Purpose To explore outcomes of endolymphatic sac surgery for patients with Meniere's disease with and without the comorbid condition of migraine. Materials and Methods A retrospective chart review of adult patients undergoing endolymphatic sac surgery at a single tertiary care center from 1987 to 2019 was performed. All adult patients who failed medical therapy and underwent primary endolymphatic sac surgery were included. The main outcome measures were vertigo control and functional level scale (FLS) score. Patient characteristics, comorbidities, and audiometric outcomes were tracked as well. Results Patients with Meniere's disease and migraine had a stronger association with psychiatric comorbidities (64.29% vs. 25.80%, p=0.01), shorter duration of vertigo episodes (143 vs. 393 min, p=0.02), and younger age (36.6 vs. 50.8 yr, p=0.005) at the time of endolymphatic sac surgery. Postoperative pure tone averages and word recognition scores were nearly identical to preoperative baselines. Class A vertigo control (47.92%) was most common, followed by class B vertigo control (31.25%). The FLS score improved from 4.2 to 2.8 (p < 0.001). Both patients with and without migraine had classes A-B vertigo control (66.67% vs. 80.95%) without any statistically significant difference (p=0.59). Of the patients who required secondary treatment (10.42%), none had migraine. Conclusions Endolymphatic sac surgery is an effective surgical intervention for Meniere's disease with and without migraine. Patients with comorbid migraine tend to be younger and present with psychiatric comorbidities.

Abstract
OBJECTIVE Ensuring that patients with dizziness present to the most appropriate level of care and provider are key goals of quality and cost improvement efforts. Using a symptom-defined cohort of adults presenting for dizziness evaluations, we aimed to identify patient factors associated with ambulatory clinic vs emergency department (ED) presentations, evaluating provider specialty, and assigned diagnoses. STUDY DESIGN Cross-sectional study. SETTING OptumLabs Data Warehouse (OLDW), a longitudinal, real-world data asset with deidentified administrative claims. METHODS We performed a cross-sectional analysis of adults (older than 18 years) who received new dizziness diagnoses (2006-2015) and identified factors associated with setting and provider at initial presentation using multivariable regression models. RESULTS Of 805,454 individuals with dizziness (median age 52 years, 62% women, 29% black, Asian, or Hispanic), 23% presented to EDs and 77% to clinics (76% primary care, 7% otolaryngology, 5% cardiology, 3% neurology). Predictors of ED presentation were younger age, male sex, black race, lower education, and medical comorbidity. Predictors of primary care clinic presentation were older age and race/ethnicity other than white. Nonetiologic symptom diagnoses alone were assigned to 51% and were most associated with age older than 75 years (odds ratio, 2.90; 95% CI, 2.86-2.94). CONCLUSION Adults with dizziness often present to a level of care that may be higher than is optimal. Differential care seeking and diagnoses by age, sex, and race/ethnicity reflect influences beyond dizziness presentation acuity. Targeted patient resources, triage systems, provider education, and cross-specialty partnerships are needed to direct dizzy patients to appropriate settings and providers to improve care.

Abstract
OBJECTIVE Intratympanic therapies, usually including glucocorticoid and gentamicin, are becoming worldwide used in clinical practice of Ménière's disease today. However, clinical efficacy and safety of these two therapies are still in controversial. DATA SOURCES Electronic searches in PubMed, CENTRAL, Web of Science, EMBASE, CINAHL, ClinicalTrials.gov and the European Union Clinical Trials Register were conducted from inception until September 2020. REVIEW METHODS The pre-specified protocol of this systematic review and meta-analysis has been registered and published in November 2018 (PROSPERO Identifier: CRD42018114389). All randomized controlled trials of intratympanic gentamicin or glucocorticoids for Ménière's disease, compared with each other or placebo, were considered for this review. RESULTS Ten studies with 455 patients met the inclusion criteria. Pooled results indicated significant advantage of intratympanic gentamicin and glucocorticoids over placebo treatments in vertigo control (gentamicin vs placebo: risk rate, RR, 2.56; 95% CI 1.18-5.54; glucocorticoids vs placebo: RR, 3.02; 95% CI 1.36-6.73). There was no significant difference between gentamicin and glucocorticoids in vertigo control (gentamicin vs placebo: RR, 1.18; 95% CI 0.97-1.45). Intratympanic glucocorticoids showed better hearing protective results than gentamicin (change of pure tone audiometric, PTA, mean difference, MD, - 6.48 dB; 95% CI - 11.84 to - 1.13 dB; change of speech discrimination scale, SDS, MD 7.69%; 95% CI 0.83-14.55%). CONCLUSIONS Intratympanic gentamicin and glucocorticoids are two effective approaches to control vertigo symptoms for Ménière's disease. Glucocorticoids showed a potentially better hearing protective role over gentamicin.

Abstract
OBJECTIVES The aim was to evaluate endolymphatic hydrops in patients with Ménière's disease before and after vestibular neurectomy to verify if the endolymphatic space dilatation, observed in magnetic resonance imaging, regressed within several months after surgery. METHODS Magnetic resonance imaging was performed after intravenous gadolinium injection in four patients with unilateral definite Ménière's disease before and eight months after vestibular neurectomy. Clinical symptoms, audiovestibular tests, and endolymphatic hydrops in magnetic resonance imaging were evaluated. RESULTS Endolymphatic hydrops was visualized in preoperative magnetic resonance imaging in three out of four analyzed patients. In the remaining one, an asymmetrical contrast enhancement in the affected ear was found. After the vestibular neurectomy, all four patients presented a complete resolution of vertigo episodes and improved functional level. Significant postoperative hearing deterioration was found in two patients. In the follow-up magnetic resonance imaging, no reduction of the endolymphatic hydrops was visualized. A reduction of asymmetrical contrast enhancement in one patient was found. CONCLUSIONS Magnetic resonance imaging of the inner ear is a helpful diagnostic tool for Menière's disease. Vestibular neurectomy is an effective treatment for intractable vertigo; however, there is no endolymphatic hydrops regression evidence within several months after the surgery. Therefore, further studies with a long follow-up period and repeated magnetic resonance imaging are needed to assess the vestibular neurectomy's impact on endolymphatic hydrops. Nevertheless, magnetic resonance imaging supports the clinical diagnosis of Ménière's disease and may help understand its pathophysiology.

Abstract
Peripheral vestibular disease can be treated with several approaches (e.g., maneuvers, surgery, or medical approach). Comorbidity is common in elderly patients, so polytherapy is used, but it can generate the development of drug-drug interactions (DDIs) that play a role in both adverse drug reactions and reduced adherence. For this reason, they need a complex kind of approach, considering all their individual characteristics. Physicians must be able to prescribe and deprescribe drugs based on a solid knowledge of pharmacokinetics, pharmacodynamics, and clinical indications. Moreover, full information is required to reach a real therapeutic alliance, to improve the safety of care and reduce possible malpractice claims related to drug-drug interactions. In this review, using PubMed, Embase, and Cochrane library, we searched articles published until 30 August 2021, and described both pharmacokinetic and pharmacodynamic DDIs in patients with vestibular disorders, focusing the interest on their clinical implications and on risk management strategies.

Vestibular Rehabilitation for Peripheral Vestibular Hypofunction: An Updated Clinical Practice Guideline From the Academy of Neurologic Physical Therapy of the American Physical Therapy Association. J Neurol Phys Ther 2021; 46:118-177. [PMID: 34864777 PMCID: PMC8920012 DOI: 10.1097/npt.0000000000000382] [Citation(s) in RCA: 91] [Impact Index Per Article: 30.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
Background: Uncompensated vestibular hypofunction can result in symptoms of dizziness, imbalance, and/or oscillopsia, gaze and gait instability, and impaired navigation and spatial orientation; thus, may negatively impact an individual's quality of life, ability to perform activities of daily living, drive, and work. It is estimated that one-third of adults in the United States have vestibular dysfunction and the incidence increases with age. There is strong evidence supporting vestibular physical therapy for reducing symptoms, improving gaze and postural stability, and improving function in individuals with vestibular hypofunction. The purpose of this revised clinical practice guideline is to improve quality of care and outcomes for individuals with acute, subacute, and chronic unilateral and bilateral vestibular hypofunction by providing evidence-based recommendations regarding appropriate exercises. Methods: These guidelines are a revision of the 2016 guidelines and involved a systematic review of the literature published since 2015 through June 2020 across 6 databases. Article types included meta-analyses, systematic reviews, randomized controlled trials, cohort studies, case-control series, and case series for human subjects, published in English. Sixty-seven articles were identified as relevant to this clinical practice guideline and critically appraised for level of evidence. Results: Based on strong evidence, clinicians should offer vestibular rehabilitation to adults with unilateral and bilateral vestibular hypofunction who present with impairments, activity limitations, and participation restrictions related to the vestibular deficit. Based on strong evidence and a preponderance of harm over benefit, clinicians should not include voluntary saccadic or smooth-pursuit eye movements in isolation (ie, without head movement) to promote gaze stability. Based on moderate to strong evidence, clinicians may offer specific exercise techniques to target identified activity limitations and participation restrictions, including virtual reality or augmented sensory feedback. Based on strong evidence and in consideration of patient preference, clinicians should offer supervised vestibular rehabilitation. Based on moderate to weak evidence, clinicians may prescribe weekly clinic visits plus a home exercise program of gaze stabilization exercises consisting of a minimum of: (1) 3 times per day for a total of at least 12 minutes daily for individuals with acute/subacute unilateral vestibular hypofunction; (2) 3 to 5 times per day for a total of at least 20 minutes daily for 4 to 6 weeks for individuals with chronic unilateral vestibular hypofunction; (3) 3 to 5 times per day for a total of 20 to 40 minutes daily for approximately 5 to 7 weeks for individuals with bilateral vestibular hypofunction. Based on moderate evidence, clinicians may prescribe static and dynamic balance exercises for a minimum of 20 minutes daily for at least 4 to 6 weeks for individuals with chronic unilateral vestibular hypofunction and, based on expert opinion, for a minimum of 6 to 9 weeks for individuals with bilateral vestibular hypofunction. Based on moderate evidence, clinicians may use achievement of primary goals, resolution of symptoms, normalized balance and vestibular function, or plateau in progress as reasons for stopping therapy. Based on moderate to strong evidence, clinicians may evaluate factors, including time from onset of symptoms, comorbidities, cognitive function, and use of medication that could modify rehabilitation outcomes. Discussion: Recent evidence supports the original recommendations from the 2016 guidelines. There is strong evidence that vestibular physical therapy provides a clear and substantial benefit to individuals with unilateral and bilateral vestibular hypofunction. Limitations: The focus of the guideline was on peripheral vestibular hypofunction; thus, the recommendations of the guideline may not apply to individuals with central vestibular disorders. One criterion for study inclusion was that vestibular hypofunction was determined based on objective vestibular function tests. This guideline may not apply to individuals who report symptoms of dizziness, imbalance, and/or oscillopsia without a diagnosis of vestibular hypofunction. Disclaimer: These recommendations are intended as a guide to optimize rehabilitation outcomes for individuals undergoing vestibular physical therapy. The contents of this guideline were developed with support from the American Physical Therapy Association and the Academy of Neurologic Physical Therapy using a rigorous review process. The authors declared no conflict of interest and maintained editorial independence.

Effect of Dexamethasone Combination with Gentamicin in Chemical Labyrinthectomy on Hearing Preservation and Vertigo Control in Patients with Unilateral Meniere's Disease: A Randomized Controlled Clinical Trial. J Clin Med 2021; 10:jcm10235581. [PMID: 34884281 PMCID: PMC8658607 DOI: 10.3390/jcm10235581] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 11/22/2021] [Accepted: 11/25/2021] [Indexed: 12/03/2022] Open
Abstract
Chemical labyrinthectomy using gentamicin is a popular method for treating intractable vertigo attacks in Meniere’s disease. However, the risk of hearing loss remains a major concern for clinicians. We investigated the effect of simultaneous dexamethasone and gentamicin application on hearing preservation and vertigo control in patients with intractable unilateral Meniere’s disease. A single-institutional, prospective, single-blinded, randomized clinical trial was conducted. Gentamicin-soaked Gelfoam® was directly applied on the oval window following middle ear exploration. On the round window, dexamethasone-soaked Gelfoam® was applied in the gentamicin with dexamethasone group (GD group, n = 18), and saline-soaked Gelfoam® was applied in the gentamicin with sham reagent group (GO group, n = 19). The hearing change 8 weeks after the procedure and vertigo control 2–12 months after the procedure were investigated. The high-frequency hearing threshold was significantly increased in the GO group (p = 0.005 and 0.012 for 4 and 8 kHz, respectively), but not in the GD group. The short-term (2–6 months) vertigo control was more successful in the GD group (57.89% vs. 94.44%, p = 0.019), but long-term control (6–12 months) was insignificant. In conclusion, the combined application of gentamicin and dexamethasone in chemical labyrinthectomy is an effective method for protecting high-frequency hearing and vertigo control.

Abstract
Cervicogenic dizziness (CGD) is a clinical syndrome characterized by an illusory sensation of motion and disequilibrium secondary to neck pathologies. Reported here is the case of a 40-year-old male presented with neck pain, dizziness, and aural symptoms in the past 12 months. The patient was previously diagnosed with Meniere’s disease and treated with a low-sodium diet, betahistine and vestibular rehabilitation for 4 months, but the symptoms had not been relieved. Subsequently he sought out chiropractic evaluation. Radiographic clues illustrated a subtle anterolisthesis of the occiput on the cervical spine, manifested by a dissociation of the clivo-axial angle (CXA). After exclusion of other neurological, vascular and vestibular causes, craniocervical instability was considered as the cause of the CGD. He was treated with multi-component intervention consisting of spinal manipulation, intermittent motorized traction and ultrasound therapy to release cervical complaints. The patient reported salutary consequences to the 3-month treatment course with no neurologic sequelae. The current study serves as a vivid example of identifying CGD based on a subtle radiographic clue and by utilizing CXA as an assessment tool for craniocervical instability.

Abstract
PURPOSE To systematically appraise clinical practice guidelines for the diagnosis and treatment of Ménière's disease using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. MATERIALS AND METHODS A systematic literature search was performed to identify guidelines pertaining to the diagnosis and treatment of Ménière's disease. Data were abstracted from guidelines that met inclusion criteria and appraised by four independent reviewers in the six domains of quality defined by the AGREE II. Domain scores reflecting quality in each domain were calculated. Intraclass correlation coefficients (ICC) were calculated across domains to qualify interrater reliability. RESULTS Six guidelines were found to meet inclusion criteria after a systematic literature search. Of the six clinical practice guidelines appraised using the AGREE II, the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guideline received the highest average score, with a mean of 90.7% spanning six quality domains. The guideline with the lowest average score across all domains was the European Position Statement on diagnosis and treatment of Ménière's disease, receiving an average score across domains of 34.6%. Overall quality scores of clinical practice guidelines for Ménière's disease had a standard deviation of 21.3%. Two guidelines met the quality threshold of > 60% in at least five domains, qualifying as 'high': AAO-HNS and National Institute for Health and Care Excellence. Average ICC across all six domains was 0.87, suggesting near total agreement between reviewers. CONCLUSION Ménière's disease remains a challenging entity to diagnose and treat; few existing clinical guidelines meet the standards of quality established by the AGREE II appraisal instrument.

Nutraceuticals for Peripheral Vestibular Pathology: Properties, Usefulness, Future Perspectives and Medico-Legal Aspects. Nutrients 2021; 13:nu13103646.

Abstract
Vestibular disorders may generate complex signs and symptoms, which may alter patients' balance and the quality of life. Dizziness and vertigo can strongly affect daily activities and relations. Despite the presence of conventional drugs, maneuvers, and surgery, another interesting therapeutic opportunity is offered by nutraceuticals. These molecules are often used in the treatment of dizziness and vertigo, but the rationale of their application is not always solidly demonstrated by the scientific evidence. Several substances have shown a variable level of efficacy/usefulness in this field, but there is lack of important evidence for most of them. From a medico-legal point of view, specific information must be provided to the patient regarding the efficacy and possibilities that the use of these preparations can allow. Administering the right nutraceutical to the proper patient is a fundamental clinical skill. Integrating conventional drug treatment with nutraceutical administration seems to be easy, but it may be difficult considering the (in part unexplored) pharmacodynamics and pharmacokinetics of nutraceuticals. The aim of the scientific community should be to elevate nutraceuticals to the same law and technical dignity of conventional drugs.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) pandemic represented a stressful event. OBJECTIVES The incidence of newly diagnosed Ménière's disease (MD) patients before and during COVID-19 at our Institution was calculated. MATERIALS AND METHODS The period 2018-2020 was considered. Incidence was calculated as number of annual first MD diagnoses divided by the number of annual first audiological evaluations. RESULTS One hundred and eighty-three patients were considered. Annual incidence of MD at our institution was 1.3% in 2018, 1.2% in 2019, and 3.2% in 2020, resulting in a significant increase during COVID-19 pandemic (2018 vs. 2020, p=.00001; 2019 vs. 2020, p=.00001). MD patients in 2020 presented a higher number of vertigo attacks (2018 vs. 2020, p=.04; 2019 vs. 2020, p=.04) and higher Dizziness Handicap Inventory questionnaire (DHI) values (2018 vs. 2020, p=.02; 2019 vs. 2020, p=.03). During COVD-19 pandemic, MD patients reported significantly higher State-Trait Anxiety Inventory (STAI) - Y1 (2018 vs. 2020, p=.04; 2019 vs. 2020, p=.03). CONCLUSIONS AND SIGNIFICANCE A higher incidence of MD first diagnosis was calculated during COVID-19 pandemic; furthermore, MD patients presented with more vertigo attacks and higher DHI values. These could be associated with the higher state anxiety during COVID-19 pandemic.
