[PMID: 38391776 PMCID: PMC10885978 DOI: 10.3390/audiolres14010019] [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: 12/03/2023] [Revised: 01/24/2024] [Accepted: 02/05/2024] [Indexed: 02/24/2024] Open
Abstract
The aim of the present study was to investigate adverse effects of head injury, neck trauma, and chronic noise exposure on the complaint profile in people with Ménière's disease (MD). The study used a retrospective design. Register data of 912 patients with MD from the Finnish Ménière Federation database were studied. The data comprised case histories of traumatic brain injury (TBI), neck trauma and occupational noise exposure, MD specific complaints, impact related questions, and the E-Qol health-related quality of life instrument. TBI was classified based on mild, moderate, and severe categories of transient loss of consciousness (TLoC). The mean age of the participants was 60.2 years, the mean duration of the disease was 12.6 years, and 78.7% were females. Logistic regression analysis, linear correlation, and pairwise comparisons were used in evaluating the associations. 19.2% of the participants with MD had a history of TBI. The phenotype of participants with TBI was associated with frequent vestibular drop attacks (VDA), presyncope, headache-associated vertigo, and a reduction in the E-QoL. Logistic regression analysis explained the variability of mild TBI in 6.8%. A history of neck trauma was present in 10.8% of the participants. Neck trauma associated with vertigo (NTwV) was seen in 47 and not associated with vertigo in 52 participants. The phenotype of NTwV was associated with balance problems, VDA, physical strain-induced vertigo, and hyperacusia. Logistic regression analysis explained 8.7% of the variability of the complaint profile. Occupational noise exposure was recorded in 25.4% of the participants and correlated with the greater impact of tinnitus, hyperacusis, and hearing loss. Neither the frequency, duration, or severity of vertigo or nausea were significantly different between the baseline group and the TBI, NTwV, or noise-exposure groups. The results indicate that TBI and NTwV are common among MD patients and may cause a confounder effect.

Treatment efficacy of repositioning maneuvers in multiple canal benign paroxysmal positional vertigo: a systematic review and meta-analysis. Front Neurol 2023; 14:1288150. [PMID: 38020643 PMCID: PMC10658715 DOI: 10.3389/fneur.2023.1288150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Accepted: 10/20/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Benign paroxysmal positional vertigo (BPPV) involving the posterior canal is more common than other canals; however, simultaneous involvement of multiple canals can be seen up to 20% of all BPPV cases. The diagnosis and management of multiple canal BPPV can be quite challenging due to the complexity of findings. Therefore, this systematic review and meta-analysis aimed at unveiling the most effective repositioning strategy for the treatment of multiple canal BPPV. Methods A literature search through PubMed, Scopus, and Web of Science databases was conducted using search terms such as BPPV, multiple canals, bilateral BPPV, repositioning maneuvers etc. After duplicate removal, the retained articles underwent various stages of elimination by two independent reviewers, and a third reviewer resolved the discrepancy between them. Results A total of 22 articles were included in the systematic review. These publications documented 5,196 patients diagnosed with BPPV, of which 513 had multiple canal BPPV. Of 295 individuals with multiple canal BPPV, 58.9% were effectively treated in 1 session, whereas 18.3 and 4.4% achieved a symptom-free state after two and three sessions, respectively. Failure of treatment using repositioning maneuvers was found in 18.4%. Possible implications This study offers insight into the real world of BPPV management in single and multiple canal BPPV. It is evident that repositioning maneuvers provide rapid and long-lasting relief of BPPV in most single canal BPPV patients; however, multiple canal BPPV often requires repeated treatment, and the risk of recurrence is higher in this variety than the single canal BPPV.

Abstract
BackgroundDizziness and imbalance are common following traumatic brain injury (TBI). While these symptoms are often attributed to vestibular dysfunction, the relative contribution of peripheral vs. central mechanisms is unclear. This study investigated the prevalence of semicircular canal and otolith abnormalities in a cohort of patients with chronic TBI and symptoms of dizziness or imbalance. The relationship between vestibular, oculomotor and posturography results was further explored.MethodsClinical records of patients attending the New Zealand Dizziness and Balance Centre from January 2015 to December 2019 were reviewed for consideration in the study. Inclusion required: an age of 18–80 years, a diagnosed TBI, and vestibular assessment using three-dimensional video head impulses (vHIT), cervical and ocular vestibular-evoked myogenic potentials (c and o VEMPs, respectively) and caloric testing. Severe TBI, pre-existing vestibular diagnoses, and incomplete test results were excluded. Rates of abnormalities were determined for each test and compared with results of oculomotor function testing and postural control, measured using the sensory organization test (SOT).ResultsOf 158 reviewed records, 99 patients aged 49 ± 15 years (59 female) fulfilled criteria for inclusion in the study. The median time between the head injury and the clinical assessment was 12 (IQR 6–21) months. Abnormalities involving one or more components of the vestibular labyrinth and/or nerve divisions were identified in 33 of 99 patients (33.3%). The horizontal semicircular canal was most frequently affected (18.2%), followed by the saccule (14.1%), utricle (8.1%), posterior (7.1%) and anterior (2.0%) semicircular canals. Vestibular test abnormalities were associated with skull-base fractures, superior canal dehiscence, and focal ear trauma. Oculomotor dysfunction and postural instability were recorded in 41.1 and 75.5% of patients, respectively. Postural instability correlated with abnormal oculomotor function (p = 0.008) but not peripheral vestibular hypofunction (p = 0.336).ConclusionsDizziness and/or imbalance in chronic TBI was associated with impaired postural stability for tasks requiring high levels of use of vestibular and visual input for balance. Vestibular hypofunction identified through vHIT, VEMP and caloric testing was recorded but was less common, except when the injury involved a fractured skull-base. There was no specific pattern of end-organ or nerve involvement which characterized this group of patients.

Abstract
OBJECTIVES Benign paroxysmal positional vertigo (BPPV) is a disorder of the inner ear with a high rate of recurrence. Vascular disorders, migraine and autoimmune disorders have been considered facilitating factors for relapsing episodes. Our aim was to assess the role of vascular disorders, migraine and anti-thyroid antibodies in patients with recurrences. METHODS We retrospectively analysed records of 3042 patients treated for BPPV without other lifetime vertigo. Clinical data included previous vascular disorders of the central nervous system, heart disorders, migraine and recent head trauma. The presence of anti-thyroid autoantibodies was assessed in all patients. RESULTS Mean age of the first BPPV was 52.8 ± 14.5 years; there were 2339 females (76.9%), while 2048 (67.3%) of patients presented recurrences within two years of follow-up. Previous disorders of the central nervous system, presence of anti-thyroid antibodies, head trauma and migraine showed an association with recurrences. Above all, in subjects having the first BPPV while aged between 40 and 60 years, anti-thyroid antibodies were predictive for recurrences. CONCLUSIONS Our data are consistent with the hypothesis that anti-thyroid autoantibodies may play a role in recurrences in subjects with initial manifestations between 40 and 60 years.

Management of unfavorable outcome after mild traumatic brain injury: Review of physical and cognitive rehabilitation and of psychological care in post-concussive syndrome. Neurochirurgie 2020; 67:283-289. [PMID: 33049290 DOI: 10.1016/j.neuchi.2020.09.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 08/26/2020] [Accepted: 09/13/2020] [Indexed: 12/19/2022]
Abstract
INTRODUCTION Mild Traumatic Brain Injury (mTBI) is a public health issue with approximately 42 million people worldwide affected yearly. Most patients have a favorable short-term recovery but 10-20% are likely to develop post-concussive syndrome (association of physical, cognitive, and psychological difficulties after injury). Post-concussive syndrome can be associated with Post-Traumatic Stress Disorder (PTSD). There is to date no recommendation on the interventions that could be done to reduce post-concussive syndrome. The present review aims at summarizing the effect of therapeutic education, physical and cognitive rehabilitation and of psychological care in mTBI patients with post-concussive syndrome. METHODS In the current international literature, we investigated the effects of therapeutic education, physical and cognitive rehabilitation and of psychological care in this population using the Medline database and we discussed the results of these studies. RESULTS The application of a therapeutic education intervention within 3 months after mTBI has been found appropriate and effective to prevent post-concussion syndrome in several studies but the timeline of this intervention differs among the existing studies. Concerning physical disabilities, several pharmacological, rehabilitative and non-pharmacological techniques have shown some efficacy in reducing headache and vertigo; rTMS seems also promising in this context. The management of fatigue is also crucial and requires a multidisciplinary approach. We did not find any intervention in mTBI patients with post-concussive syndrome suffering from dysosmia and/or dysgueusia. No pharmacological treatment is currently recommended to reduce the cognitive symptoms of post-concussive syndrome after mTBI. Rehabilitation and brain-stimulation techniques have already proven their efficacy to reduce the cognitive impairment in this population. Even if the use of Virtual Reality software seems well tolerated in this population, its efficacy and additional value needs to be demonstrated in larger studies. Concerning the psychological care after mTBI, Cognitive and Behavioral Therapy interventions are the most frequently reported in this population, followed by psychoeducational interventions. PTSD management seems crucial in overall recovery of patients with post-concussive syndrome. CONCLUSION Many studies have sought to demonstrate the effectiveness of various rehabilitation techniques, including different cognitive rehabilitation programs, technology-assisted rehabilitation, different types of brain stimulation and some pharmacological treatments. However, most of these studies are of a low level of scientific evidence and it would be necessary to carry out well-conducted prospective randomized trials in order to offer an appropriate and effective multidisciplinary management for patients with post-concussive syndrome after mTBI.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) has a high recurrence rate, but the risk factor-associated recurrence are elusive. METHODS Searches were performed in PubMed, Embase, Cochrane library, Web of science, Chinese National Knowledge Infrastructure, and Sino Med up to November 3, 2019. The effect size was analyzed by odds ratio and 95% CI. Data from eligible studies were meta-analyzed using Stata version 15.0. RESULTS Our search resulted in a total of 4076 hits. Twenty-four outcomes of sixty articles were included in the meta-analysis. Risk factors for the recurrence of BPPV included female gender, age (≥65years), hyperlipidemia, diabetes, hypertension, migraine, cervical spondylosis, osteopenia/osteoporosis, head trauma, otitis media, abnormal vestibular evoked myogenic potential, and long use of computers. No significant differences were found in side, type of the involved semicircular canals, smoking, alcohol consumption, stroke, ear surgery, duration of vertigo before treatment, the times of repositioning, Meniere disease, sleep disorders, hypercholesterolemia, and 25-hydroxy vitamin D. CONCLUSION These findings strengthen clinical awareness of early warning to identify patients with potential relapse risk of BPPV and clinicians should counsel patients regarding the importance of follow-up after diagnosis of BPPV.

Abstract
Objective: To investigate the possible role of superoxide dismutases (SODs) in the development of benign paroxysmal positional vertigo (BPPV) and recurrence events in a 1-year follow-up study. Methods: This was a prospective one-center study. A total of 204 patients with BPPV and 120 age-and sex matched healthy subjects were included. The levels of SOD between patients and control cases were compared. The levels of SOD between posterior semicircular canal (PSC) and horizontal semicircular canal (HSC) were also compared. In the 1-year follow-up, recurrence events were confirmed. The influence of SOD levels on BPPV and recurrent BPPV were performed by binary logistic regression analysis. Results: The serum levels of SOD in patients with BPPV were lower than in those control cases (P<0.001). Levels of SOD did not differ in patients with PSC and HSC (P=0.42). As a categorical variable, for per interquartile range (IQR) increment of serum level of SOD, the unadjusted and adjusted risks of BPPV would be decreased by 72% (with the odds ratio [OR] of 0.28 [95% confidence interval (CI): 0.21–0.37], P<0.001) and 43% (0.57 [0.42–0.69], P<0.001), respectively. Recurrent attacks of BPPV were reported in 50 patients (24.5%). Patients with recurrent BPPV had lower levels of SOD than in patients without (P<0.001). For per IQR increment of serum level of SOD, the unadjusted and adjusted risks of BPPV would be decreased by 51% (with the OR of 0.49 [95% CI: 0.36–0.68], P<0.001) and 24% (0.76 [0.60–0.83], P<0.001), respectively. Conclusion: Reduced serum levels of SOD were associated with higher risk of BPPV and BPPV recurrence events.

Abstract
PURPOSE OF REVIEW To provide an overview of vestibular lab testing and to familiarize the reader with common results observed in headache patients with dizziness. RECENT FINDINGS The latest research indicates variable levels of both peripheral and central vestibular dysfunction in headache populations with dizziness. Mechanisms may include vestibulocerebellar loss of inhibition, central vestibular network misfiring, and peripheral pathology aggravating central hypersensitization. Headache patients are commonly affected by dizziness stemming from various etiologies. Although history is still the gold standard in diagnosis, vestibular lab testing can identify the integrity of vestibular function. Research is emerging and future directions are encouraging.

Abstract
Background: So far, there has been a controversy surrounding repositioning difficulty and recurrence rate between traumatic benign paroxysmal positional vertigo (t-BPPV) and idiopathic BPPV (i-BPPV). Objectives: This meta-analysis was aimed to explore whether or not the differences between t-BPPV and i-BPPV in the repositioning difficulty and recurrence rate existed. Material and methods: A literature search was performed in the databases including Pubmed, Embase, CENTRAL, which completed in 21 January 2019, with no restriction of publication language. Relative risk (RR) of number of repositioning maneuvers and the recurrence rate was calculated with its 95% confidence interval. Sensitive analysis was performed simultaneously. Results: Six retrospective cohort studies were included in our meta-analysis, including 865 t-BPPV patients and 3027 i-BPPV patients. All studies were high quality according to Newcastle-Ottawa Scale (NOS) assessment. Patients with t-BPPV required more repositioning maneuvers for resolution than those with i-BPPV (RR = 3.27, 95% CI = 1.88-5.69, p < .0001), and the recurrence rate of t-BPPV was higher than that of i-BPPV (RR = 2.91, 95% CI = 2.04-4.14, p < .00001). Conclusions and significance: Compared with i-BPPV, patients with t-BPPV require more repositioning maneuvers to resolve, and the recurrence of t-BPPV was more frequent.

Abstract
Objective: We aimed to assess the possible relations between serum levels of macrophage migration inhibitory factor (MIF), a central cytokine of the innate immunity and inflammatory response, and benign paroxysmal positional vertigo (BPPV) risk and BPPV recurrence events. Methods: In the present study, 154 patients with BPPV, and 100 age-and sex-matched control subjects were enrolled in the study. All the patients and controls underwent a complete audio‐vestibular test battery including the Dix–Hallpike maneuver and supine roll test. In the BPPV group, measurements of MIF levels were repeated 1 month after the vertigo attack. The patients were also divided into the recurrence group and the nonrecurrence group in the 1-year follow-up. Results: The serum levels of MIF in patients with BPPV were higher than in those controls (13.9[interquartile range {IQR}, 8.9–18.4] ng/ml vs. 9.8[7.8–11.8]; P<0.001). As a continuous variable, MIF was associated with increased risk of BPPV (odds ratio [OR] 1.21, 95% confidence interval [CI]: 1.11–1.39; P=0.004) in multiple regression analyses. Recurrent attacks of BPPV were reported in 35 patients, and those patients had higher levels of MIF than those patients were not recurrence (18.0[IQR, 13.6–22.2] ng/ml vs. 12.6[9.3–16.8] ng/ml). In multivariate models comparing the second (Q2), third (Q3) and fourth(Q4) quartiles against the first (Q1) quartile of MIF, levels of MIF in Q4 were associated with recurrent BPPV, and the odds were increased by approximately 305% (OR = 4.05; 95%CI: 1.65–15.44; P=0.009). Conclusions: Elevated MIF is positively correlated with BPPV risk and BPPV recurrence events, requiring further efforts to clarify the exact mechanism.
