Conclusion:The elevated neutrophil-to-lymphocyte ratio (NLR) value in children with sudden sensorineural hearing loss (SSNHL) would suggest the inflammatory etiology of pediatric SSNHL. The results of this study may suggest NLR value can be used as a useful indicator, which is associated with the disease severity in pediatric SSNHL. Objectives:This study aimed to elucidate any clues of inflammatory etiology, which might be related with the development of pediatric SSNHL, using calculated NLR. Methods:Forty-six patients aged younger than 19 years, who were admitted to the hospital with the diagnosis of SSNHL, were included in the study. Forty-six healthy children were matched as control group according to their propensity score. The complete blood cell count, calculated NLR, platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) were compared. The relationship between NLR and the initial hearing level was also investigated. Results:The mean NLR value was 2.86 ± 2.58 in the SSNHL group, whereas the mean NLR value was 1.63 ± 0.87 in the control group. The mean NLR value of the SSNHL children was significantly higher than that of the control group (p = .023). There was a positive correlation between the NLR value and initial hearing level (r = .312,p = .037). [ABSTRACT FROM PUBLISHER]

Objective: To identify the prevalence of and relevant information for video head impulse test (vHIT) abnormality in a large population., Study Design: A cross-sectional design., Setting: Korean National Health and Nutrition Examination Survey, 2021., Methods: The sample was representative of the Korean population, with 2237 participants aged ≥40 years. A vHIT was performed to evaluate vestibular function. The vestibulo-ocular reflex (VOR) gain and the presence of reproducible catch-up saccades was assessed in a vHIT. Participants also completed questionnaires for demographics, socioeconomic status, and basic information regarding systemic diseases and dizziness and underwent hearing tests with automated pure-tone audiometry., Results: The prevalence of vHIT abnormality was 22.5%, with unilateral (14.3%) being more common than bilateral (8.2%). The prevalence of vHIT abnormality increased significantly with age, with the highest rate observed in individuals aged >70 years (42.5%). Both hearing and VOR gain deteriorated with age, but the patterns of age-related progression were different. While hearing loss (HL) deteriorated gradually and progressively throughout adulthood, VOR gain deterioration was markedly evident after 70 years of age., Conclusion: Considering the high prevalence of vHIT abnormality, appropriate social and medical policies are needed to prevent associated injuries and improve patients' quality of life. The distinct age-related changes in HL and objective findings of vestibular dysfunction indicate the need for different approaches to address these social problems in aging countries., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Objectives: Some patients with dizziness show high comorbidity with psychiatric disorders. However, the association of vestibular deficit with psychological symptoms remains controversial. Thus, we investigated psychological distress (depression and anxiety) in patients with vestibular disease and examined factors modifying the development of psychological distress in these patients, including age, sex, severity of dizziness symptoms, and type of vestibular disease., Study Design: Prospective study., Setting: Tertiary referral center., Subjects and Methods: This study enrolled 407 patients with dizziness. Dizziness and the psychological symptoms of all patients were measured using the Korean versions of the Dizziness Handicap Inventory (DHI), the Beck Depression Inventory (BDI), and the Spielberger State-Trait Anxiety Inventory (STAI). We evaluated the influence of vestibular disease type, DHI score, and other factors such as sex and age on the psychological scales (BDI, STAI) through multiple regression analysis., Results: Only DHI score and vestibular neuritis were related significantly to BDI scores in patients with vestibular disease, and only DHI scores were associated with STAI scores., Conclusion: Dizziness Handicap Inventory scores and psychological distress were closely associated. Psychological distress might be a consequence of high DHI score rather than of a specific type of vestibular disease, although depressive symptoms were related to vestibular neuritis.

Conclusion: The incidence of ipsilesional beating vibration induced nystagmus (VIN) is significantly higher in Meniere's disease (MD) with lower canal paresis (CP) group on caloric test and the intensity of VIN shows significant positive correlation with CP. Considering previous reports showing predominant loss of type II hair cells in MD and discrepancy of the results between caloric test and head thrust test in MD patients, VIN may provide valuable information regarding the functional reservoir of vestibular type II hair cells in MD., Objectives: Clinical presentation of MD is dynamic and nystagmus changes phase to phase, which is attributed to the recovery process in addition to central compensation after active vertigo attack of MD. VIN has been shown to reflect the side difference of peripheral vestibular excitability and is well correlated with the severity of caloric weakness in vestibular neuritis. Aim of this study was to compare the intensity and the direction of VIN with CP in unilateral MD., Materials and Methods: 52 patients with unilateral definite MD on AAO-HNS guideline (1995) were included. Auditory and vestibular function tests including caloric test, post-head shaking nystagmus (HSN) and VIN were evaluated during symptom free period and cases with spontaneous nystagmus were excluded. Vibratory stimuli (100 Hz) were applied to either mastoid alternatively. Eye movement was recorded using video nystagmography system. The horizontal component of VIN was compared with HSN and caloric test., Results: 37 patients (71%) showed VIN. VIN to ipsilesional side was in 10 and to contralesional side in 27. In patients with CP over 43% (N =23), 2 beated to ipsilesional side, 17 to contralesional side and 4 showed no VIN. In patients with CP of less than 43% (N =29), 8 beated to ipsilesional side, 10 to contralesional side and 11 showed no VIN (p<0.05). 33 patients (63%) showed HSN and 24 patients of them (72%) showed contralesional nystagmus. The intensity of VIN shows significant positive correlation with the degree of CP on caloric test (Spearman's rho =0.340, p<0.05).
