OBJECTIVE: The aim was to evaluate endolymphatic hydrops in patients with severe Ménière\'s disease (MD) before and after vestibular neurectomy to verify if vestibular denervation results in hydrops regression.
METHODS: Magnetic resonance imaging was performed after intravenous gadolinium injection in twenty patients with unilateral definite MD before and after the vestibular neurectomy. Clinical symptoms and audiovestibular tests were evaluated. Follow-up intervals ranged from 18 to 35 months after the surgery.
RESULTS: Endolymphatic hydrops were visualized in all patients in the preoperative scans. After the vestibular neurectomy, all patients presented a complete resolution of vertigo episodes. Regression of the endolymphatic hydrops was observed in 35% and 15% of cases analyzing cochlea and vestibule, respectively. In 71.43% of patients with utricular herniation into the lateral semicircular canal, withdrawal of the hernia was visualized. Asymmetrical contrast enhancement in the cochlea regressed in 17.64% of cases. Analyzing all the parameters collectively, in 60% of patients, partial regression of at least one of the radiological signs was confirmed in the follow-up examination. No progression of the endolymphatic hydrops was visualized after the surgery in either the cochlea or the vestibule.
CONCLUSIONS: Vestibular neurectomy is an effective treatment, eliminating vertigo attacks and improving the quality of life in patients with MD. Magnetic resonance imaging of the inner ear allows visualization of changes in endolymphatic hydrops degree after treatment. Regression of the endolymphatic hydrops after vestibular neurectomy suggests that vestibular denervation may effectively halt the progression of the endolymphatic space dilatation and result in hydrops regression.

BACKGROUND: This study aimed to investigate the association of peripheral vestibular disorders with type 1 and type 2 diabetes using a population-based dataset.
METHODS: The data for this study were obtained from Taiwan\'s Longitudinal Health Insurance Database 2010. The sample consisted of 150,916 patients who were newly diagnosed with peripheral vestibular disorders as cases and 452,748 propensity-score-matching controls without peripheral vestibular disorders. We utilized multivariate logistic regression models to quantitatively evaluate the association between peripheral vestibular disorders and diabetes while considering factors such as sex, age, geographic location, monthly income, urbanization level of the patient\'s residence, coronary heart disease, hypertension, and hyperlipidemia.
RESULTS: The chi-squared test indicates that diabetes was more common in the peripheral vestibular disorder group compared to controls (20.6% vs. 15.1%, p < 0.001). Of all sampled patients, the adjusted odds ratio for diabetes was 1.597 (95% CI = 1.570~1.623) for those with peripheral vestibular disorders when compared to controls, while patients with Ménière\'s disease, benign paroxysmal positional vertigo, unilateral vestibulopathy, and other peripheral vestibular disorders had respective adjusted odds ratios of diabetes at 1.566 (95% CI = 1.498~1.638), 1.677 (95% CI = 1.603~1.755), 1.592 (95% CI = 1.504~1.685), and 1.588 (95% CI = l.555~1.621) in comparison to controls.
CONCLUSIONS: Our research has revealed an association between diabetes and an increased susceptibility to peripheral vestibular disorders.

UNASSIGNED: Acute vestibular syndrome (AVS) is a common symptom presented by emergency department (ED) patients. Differentiating peripheral from central etiology poses a challenge and clinical practice lacks a uniform diagnostic approach. This study aims to provide insight on incidence and diagnostics in ED patients presenting with AVS in the Netherlands.
UNASSIGNED: A multicenter retrospective cohort study on ED patients presenting with AVS in two hospitals during 3 years. Primary endpoints are incidence, diagnostics and diagnosis at ED versus follow-up. A secondary endpoint includes therapy.
UNASSIGNED: 500 AVS cases were included. The annual incidence was 0.1%. 85 ED patients (17.0%) were diagnosed with stroke, 285 (57.0%) with non-stroke and 130 (26.0%) with an unsure etiology. At follow-up, diagnosis was corrected in 145 patients (29.0%), with stroke missed in 29 (5.8%). A triad of clinical tests (HINTS) was reported in 106 (21.2%) patients, a CT in 342 (68.2%) and a MRI in 153 (30.6%). Antiplatelet therapy was prescribed in 135 cases. In 69% of these, initial diagnosis was corrected to non-stroke. For 8 patients who received thrombolysis, initial diagnosis was corrected in 3. Of those patients where stroke was initially not identified, 23 (79%) received suboptimal treatment in lieu of antiplatelet therapy.
UNASSIGNED: The annual incidence of AVS in Dutch ED patients is 0.1%. ED diagnosis is often uncertain, with one-third of diagnoses corrected. This study substantiates clinical practice lacks a uniform diagnostic pathway with an overuse of CT and underuse of HINTS. Further research on optimal diagnostic approach is warranted to improve treatment of AVS.

BACKGROUND: To improve diagnostic precision in pediatric vertigo, particularly in Vestibular Migraine of Childhood (VMC), probable VMC (pVMC), Recurrent Vertigo of Childhood (RVC), and unspecified categories, by delineating clinical characteristics and prevalence to refine diagnostics and treatments.
METHODS: Retrospective analysis of 102 pediatric patients (five to 18 years; 46 females, 56 males) at the Dizziness Center of the Otolaryngology Department in a tertiary-level hospital from January 2019 to December 2023. Patients were classified into VMC, pVMC, RVC, and indeterminate groups. Evaluations included audiometry and vestibular tests (video head impulse test [vHIT] or caloric testing), conducted in the audiology unit and vestibular testing laboratory. Data were analyzed using IBM SPSS 20.0.
RESULTS: Diagnoses were 8.8% VMC, 31.4% pVMC, 51.0% RVC, and 8.8% indeterminate. Nausea and vomiting were common in VMC and pVMC; cochlear symptoms like tinnitus and hearing loss predominated in VMC. Although vestibular testing showed no significant group differences, VMC had more vHIT abnormalities and RVC had more caloric test anomalies.
CONCLUSIONS: This study highlights the need for comprehensive diagnostics in pediatric vestibular disorders, revealing unique and overlapping traits across VMC, pVMC, and RVC. Insights call for further research to refine diagnostic criteria and improve treatment methods.

OBJECTIVE: To observe the clinical effect of nape seven needles combined with pressing moxibustion for cervical vertigo (CV).
METHODS: A total of 70 patients with CV were randomized into an observation group and a control group, 35 cases in each group. In the observation group, nape seven needles combined with pressing moxibustion was delivered, once a day, 6 times a week, for consecutive 2 weeks. In the control group, betahistine hydrochloride tablet and aceclofenac dispersible tablet were given orally, for 2 weeks and 3 days respectively. Before and after treatment, the evaluation scale for cervical vertigo (ESCV) score was observed, the plasma levels of neuropeptide Y (NPY), endothelin-1 (ET-1) and calcitonin gene related peptide (CGRP) were detected, the hemorheologic and hemodynamic indexes were measured, and the clinical efficacy was evaluated after treatment in the two groups.
RESULTS: After treatment, the scores of dizziness, daily life and work ability, psychological and social adaptability, and headache, as well as the total scores of ESCV were increased compared with those before treatment (P<0.01, P<0.05) in the two groups, and the score and total score of neck and shoulder pain of ESCV was increased compared with that before treatment (P<0.01) in the observation group; each sub-item score and total score of ESCV in the observation group were higher than those in the control group (P<0.01, P<0.05). After treatment, the plasma levels of NPY and ET-1 were decreased compared with those before treatment (P<0.01), while the plasma levels of CGRP were increased compared with those before treatment (P<0.01, P<0.05) in the two groups; the plasma levels of NPY and ET-1 in the observation group were lower than those in the control group (P<0.01), the plasma level of CGRP in the observation group was higher than that in the control group (P<0.01). After treatment, the whole blood high shear viscosity, plasma viscosity and whole blood low shear viscosity were decreased compared with those before treatment (P<0.01, P<0.05), the mean velocity of basilar artery (BA), left vertebral artery (LVA) and right vertebral artery (RVA) were increased compared with those before treatment (P<0.05) in the two groups; the whole blood high shear viscosity, plasma viscosity and whole blood low shear viscosity in the observation group were lower than those in the control group (P<0.01), and the mean velocity of BA, LVA and RVA in the observation group were higher than those in the control group (P<0.05). The total effective rate in the observation group was 91.4% (32/35), which was superior to 71.4% (25/35) in the control group (P<0.05).
CONCLUSIONS: Nape seven needles combined with pressing moxibustion can effectively alleviate the clinical symptoms, and improve the hemorheology and hemodynamics in CV patients.

BACKGROUND: This study aimed to evaluate the prevalence and psychometric properties of vertigo and dizziness in an obstructive sleep apnoea (OSA) population.
METHODS: Five hundred and twelve OSA patients and 53 controls were enroled. All eligible subjects were asked to complete the basic information questionnaire, the Chinese version of Vestibular Disorders Activities of Daily Living (VADL-C), the Dizziness Handicap Inventory (DHI) and the Activities-Specific Balance Confidence (ABC) scale.
RESULTS: Among 512 enroled OSA patients, a 22.46% (115) prevalence of vertigo and dizziness was found. The scores of the VADL-C, DHI and ABC of the study group were significantly worse (p < .001) than those of the control group, while the abnormal rates of the three scales in the study group were higher than those of the control group. In the study group, the results of the VADL-C were correlated with those of the DHI (r = .55, p < .001) and inversely correlated with those of the ABC (r = -.50, p < .001), and the results of the DHI were inversely correlated with those of the ABC (r = -.60, p < .001).
CONCLUSIONS: A high prevalence of vertigo and dizziness in the OSA population was detected. Psychometric results showed that vertigo and dizziness in OSA patients led to changes in activities of daily living, increased frequency of somatic symptoms, and reduced balance confidence. In the diagnosis and treatment of OSA patients, the occurrence of vertigo and dizziness is worth clinicians\' attention.

UNASSIGNED: Benign paroxysmal positional vertigo (BPPV) affects approximately half of acute, moderate-severe traumatic brain injury (TBI) patients. To date, there have been no rigorous studies of BPPV assessment or treatment in this cohort. We aimed to determine the safety, practicability, and efficacy of therapist-led BPPV management in acute TBI and the feasibility of a larger effectiveness trial.
UNASSIGNED: This was a multi-centre, three-arm, parallel-groups, randomised, feasibility trial. Recruitment was via convenience sampling. The main inclusion criteria were age over 18 years and a confirmed, non-penetrating, acute TBI. BPPV-positive patients were randomly allocated to one of three interventions (repositioning manoeuvres, Brandt-Daroff exercises or advice) using minimisation criteria. Outcome assessors were blinded to the intervention.
UNASSIGNED: Of 2014 patients screened for inclusion, 180 were assessed for BPPV. Of those assessed, 34% (62/180) had BPPV, and 58 patients received an intervention. Therapist-led interventions were delivered safely and accurately according to intervention monitoring criteria. Resolution of BPPV was observed in 35/58 (60%) patients. The resolution rate was highest following repositioning manoeuvres (78%), followed by the advice (53%) and Brandt-Daroff interventions (42%). 10 patients experienced recurrence. This was observed more frequently in those with skull fractures and bilateral or mixed BPPV.
UNASSIGNED: Overall, the results provide strong evidence for the feasibility of a future trial. Therapist-led management of BPPV in acute TBI was safe and practicable. Repositioning manoeuvres seemingly yielded a superior treatment effect. However, given the high recurrence rate of post-traumatic BPPV, the optimal time to treat according to patients\' specific recurrence risk requires further investigation.

BACKGROUND: Migraine and dizziness often coexist, with vestibular migraine (VM) presenting with vestibular symptoms and headaches. Calcitonin gene-related peptide (CGRP) may be involved in motion-induced symptoms; however, studies on the use of anti-CGRP monoclonal antibodies (mAbs) for the treatment of VM have yielded conflicting results. This study aimed to clarify the effectiveness of anti-CGRP mAbs in VM treatment.
METHODS: This retrospective observational cohort study, conducted between 1 January 2021 and 31 March 2023, assessed 12 Japanese patients with VM who were treated with anti-CGRP mAbs (CGRP group) for 6 months and 11 Japanese patients who received standard of care for VM and served as controls. Clinical questionnaires and equilibrium tests were administered, with primary outcomes including changes in Dizziness Handicap Inventory (DHI) scores compared with baseline values. Objective variables included the DHI score and explanatory variables included demographic data, balance test results, head-up tilt (HUT) test results, vestibular test results and questionnaire survey results. Analysis of variance was used to assess the treatment effects of anti-CGRP mAbs, and multivariate regression analysis was performed to identify mAb responders.
RESULTS: After 6 months, the CGRP group showed significant improvements in DHI scores [0 versus 6 months, odds ratio (95% confidence interval): 22.01 (0.13-43.88)] and number of vertigo/dizziness attacks per month [0 versus 6 months: 10.28 (2.80-17.76)]. No significant difference was observed in the control group [DHI scores, 0 versus 6 months: 0.65 (-26.84 to 28.14); number of vertigo/dizziness attacks per month, 0 versus 6 months: - 8.07 (- 23.77 to 7.62)]. Multivariate regression analysis showed that autonomic function at baseline was associated with mAb response in patients [β estimates (95% confidence interval): 3.63 (0.21-7.06)].
CONCLUSIONS: Treatment with anti-CGRP mAbs was more effective than conventional treatment in preventing migraine in patients with VM. While the identified factors associated with treatment responsiveness offer valuable insights into personalised treatment approaches, further prospective studies are warranted to validate the findings due to our study\'s retrospective design and limited sample size.

OBJECTIVE: This pilot study aimed to evaluate a training programme for primary care physiotherapists focused on the assessment and management of benign paroxysmal positional vertigo.
METHODS: A six-month training programme and toolkit utilising the revised Standards for Quality Improvement Reporting Excellence (\'SQUIRE 2.0\') guidelines was developed to facilitate the learning of new knowledge and skills in the assessment and management of benign paroxysmal positional vertigo following Gagne\'s model of instructional design. A pre- and post-training knowledge and confidence questionnaire evaluated the impact of the training programme.
RESULTS: Eleven participants started the training programme and five completed it. On average, knowledge increased by 54 per cent (range, 41-95 per cent) and confidence increased by 45 per cent (range, 31-76 per cent). A 73 per cent improvement in practical skills acquisition was demonstrated after the initial training session.
CONCLUSIONS: A structured approach to learning demonstrates improvements in knowledge, skills and confidence of physiotherapists in the evidence-based management of benign paroxysmal positional vertigo.

OBJECTIVE: To examine the newly established role of a primary contact physiotherapist in an ENT clinic, in an Australian cohort and context, over two phases of development.
METHODS: A retrospective cohort study was conducted with data collected from a medical record audit. Over the study duration, the primary contact physiotherapist completed initial appointments with patients; follow-up appointments were subsequently conducted by medical staff.
RESULTS: There was a 46 per cent reduction in patients with suggested vestibulopathy requiring an ENT medical review. This reduction could hypothetically increase to 71 per cent with follow-up primary contact physiotherapist appointments. Improvements in the service delivery model and a primary contact physiotherapist arranging diagnostic assessments could improve waitlist times and facilitate better utilisation of medical staff time.
CONCLUSIONS: The primary contact physiotherapist can help in the management of patients with suspected vestibulopathy on an ENT waitlist. This is achieved through: a reduction of patients requiring ENT review, improvements to waitlist time and improved utilisation of medical specialists\' time.
