Maladie de Ménière ; Migraines ; Vertige positionnel paroxystique benin (VPPB) (BPPV)Résumé : Les étourdissements, les vertiges et l'instabilité sont des plaintes courantes des patients qui se présentent aux fournisseurs de soins primaires. Ces patients sont souvent référés à l'otologie pour évaluation et prise en charge. Malheureusement, il existe un petit nombre de spécialistes pour gérer ces patients. Cependant, il existe plusieurs troubles vertigineux qui peuvent être gérés avec succès par les fournisseurs de soins primaires si le trouble est correctement identifié. Pour aider à l'identification de plusieurs des étourdissements les plus courants, nous avons développé le profil des symptômes d'étourdissement (DSP). Le DSP est un questionnaire d'auto-évaluation conçu pour générer un ou plusieurs diagnostics différentiels qui peuvent être combinés avec l'historique de cas et l'examen physique du patient.
Ce rapport décrit trois enquêtes. Les enquêtes 1 et 2 (c.-à-d. Enquêtes exploratoires et confirmatoires, N = 514) décrivent le développement du DSP. L'enquête 3 (N = 195) est une étude de validation qui décrit le niveau d'accord entre le DSP complété par le patient et le diagnostic différentiel de l'otologue.
La version finale du DSP comprend 31 éléments. Les résultats préliminaires suggèrent que le DSP est en accord avec les diagnostics différentiels des spécialistes de l'oreille pour la maladie de Ménière (accord à 100%), la migraine vestibulaire (accord à 95%) et le vertige positionnel paroxystique bénin (accord à 82%).
Les premiers résultats suggèrent que le DSP peut être utile dans la création de diagnostics différentiels pour les patients étourdis qui peuvent être évalués et gérés localement. Cela a le potentiel de réduire le fardeau des fournisseurs de soins primaires et de réduire les délais de diagnostic des étourdissements et des vertiges courants.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=251730

Titre : Diabetes and the Vestibular System Type de document : Article Auteurs : Erin G. Piker ; Daniel J. Romero Année de publication : 2019 Article en page(s) : p. 300-307 Langues : Anglais (eng) Descripteurs : HE Vinci
Diabète ; Système vestibulaire ; Vertige positionnel paroxystique benin (VPPB) (BPPV)Résumé : Falls are among the most injurious, costly, and feared conditions affecting older adults. Patients with diabetes have a significantly greater risk for falling due to complications affecting the sensory systems required for balance: vision, proprioception, and vestibular. The effects of diabetes mellitus on the vestibular system are perhaps the least understood of these systems. The vestibular system is complex, includes multiple structures, and is difficult and expensive to thoroughly assess. There is pathophysiologic evidence suggesting a direct effect of diabetes mellitus complications on the vestibular system, but there is limited clinical evidence regarding which specific vestibular structures are most adversely affected. Nevertheless, large population-based studies show that patients with diabetes are more likely to have vestibular loss, have a high prevalence of a specific vestibular disorder called benign paroxysmal positional vertigo, and are at a greater risk for falling. Based on the available evidence, a balance screening and an evaluation of benign paroxysmal positional vertigo, a common but easy to treat pathology, in patients with diabetes is recommended as well as counseling on falls risk and home modifications.

Titre : Maximum Output and Low-Frequency Limitations of B71 and B81 Clinical Bone Vibrators: Implications for Vestibular Evoked Potentials Type de document : Article Auteurs : Christopher G.

Potentiel évoqué auditif (PEA) ; Potentiel évoqué myogénique vestibulaire (oVEMP) (cVEMP) ; VestibulométrieRésumé : Objectives: Bone-conducted vestibular evoked myogenic potentials (VEMPs) are tuned to have their maximum amplitude in response to tone bursts at or below 250 Hz. The low-frequency limitations of clinical bone vibrators have not been established for transient, tone burst stimuli at frequencies that are optimal for eliciting VEMPs.
Design: Tone bursts with frequencies of 250 to 2000 Hz were delivered to B71 and B81 bone vibrators and their output was examined using an artificial mastoid. The lower-frequency limit of the transducers was evaluated by examining the spectral output of the bone vibrators. Maximum output levels were evaluated by measuring input-output functions across a range of stimulus levels.
Results: Both the B71 and B81 could produce transient tone bursts with frequency as low as 400 Hz. However, tone bursts with frequencies of 250 and 315 Hz resulted in output with peak spectral energy at approximately 400 Hz. From 500 to 2000 Hz, maximum output levels within the linear range were between 120 and 128 dB peak force level. The newer B81 bone vibrator had a maximum output approximately 5 dB higher than the B71 at several frequencies.
Conclusions: These findings demonstrate that both transducers can reach levels appropriate to elicit bone-conducted VEMPs, but the low-frequency limitations of these clinical bone vibrators limit tone burst frequency to approximately 400 Hz when attempting to stimulate the otolith organs via tone bursts.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=256774

Titre : Test-Retest Reliability of the Dizziness Symptom Profile Type de document : Article Auteurs : Renée Landon-Lane ; Erin G. Piker ; Gary P. Jacobson ; Kelsey Hatton ; Richard A. Roberts Année de publication : 2021 Article en page(s) : p. 206-213 Langues : Anglais (eng) Descripteurs : HE Vinci

Instabilite motrice ; Test retestRésumé : Objectives: This investigation was conducted to measure the test-retest reliability of the Dizziness Symptom Profile (DSP). The DSP was developed to assist primary care providers, general otolaryngologists, and other health care providers in the development of a differential diagnosis for patients who present with dizziness, vertigo, or unsteadiness. The DSP yields a score ranging from 0 to 100% for each of 7 subscales. Each subscale represents a different diagnosis including benign paroxysmal positional vertigo, Meniere's disease, persistent postural-perceptual dizziness (PPPD), superior semi-circular canal dehiscence, vestibular migraine, vestibular neuritis, and general unsteadiness.
Design: Subjects were 150 adult patients (mean age 56.79 years, SD 15.69 years) referred to the Balance Disorders Clinic at Vanderbilt University Medical Center. Subjects completed two administrations of the DSP. The mean interval between test administrations was 1.58 days (SD 1.78 days). The response modes for the DSP were both a 0 to 100 mm visual analog scale (scored 0 mm = "strongly disagree" to 100 mm = "strongly agree") and, by extrapolation, the original 5-point Likert scale where the anchors were "strongly disagree" (scored 0 points) and "strongly agree" (scored 4 points).
Results: Pearson correlation coefficients were calculated to assess test-retest reliability for individual DSP items, and ranged from r = 0.67 to 0.91 (mean 0.80; p 0.7) with the exception of PPPD which approached 0.7. Intraclass correlation coefficient estimates and their 95% confidence intervals were also calculated to assess the relative reliability of the subscales. All 7 subscales showed moderate to strong test-retest reliability, with intraclass correlation coefficients ranging from 0.85 to 0.94. Minimal detectable change (MDC) scores were calculated to assess absolute variability/measurement error for the seven subscale scores (which range from 0 to 100%). MDC values ranged from 16% (PPPD) to 25% (unsteadiness).
Conclusions: (1) The test-retest reliability of the DSP is moderate to strong. (2) MDC values for each subscale were determined. (3) The DSP coupled with the Dizziness Handicap Inventory enables the clinician to evaluate the constructs of dizziness impairment, and disability/handicap. (4) The DSP may help provide a window to the natural history of dizziness disease(s). (5) The DSP provides a less biased assessment of the symptoms reported by the patient.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264029
