[PMID: 38476465 PMCID: PMC10929264 DOI: 10.3389/fped.2024.1366074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 02/16/2024] [Indexed: 03/14/2024] Open
Abstract
Study background Newborn infection and sepsis remain serious problems. Guideline-compliant therapy includes, among other therapeutics, calculated intravenous antibiosis with gentamicin. One of the known side effects of gentamicin is severe vestibulotoxicity, which can be detected using the video head impulse test (VHIT), which is a sensitive examination method for the detection of vestibular hypofunction in children and adults. Previous studies on the vestibulotoxicity of gentamicin in newborns were carried out using caloric testing, rotary testing, and electronystagmography. Nevertheless, there are currently no data available on VHIT examinations in children who have been treated with neonatal gentamicin therapy. Methods A single-center, prospective cross-sectional study, was conducted at a tertial referral center. VHIT was performed on 23 children aged 3-7 years who had received intravenous gentamicin therapy for at least five days as part of the treatment of newborn sepsis between 2012 and 2016. Main outcome was median gain and occurrence of refixational saccades as measured with VHIT. In addition, the children's parents received questionnaires to detect possible risk factors and vestibular and cochlear abnormalities. Results Out of 23 children with a mean age of four years and seven months (ranging from 3 to 7 years), 11 (47.8%) indicated abnormal results in VHIT. The VHIT results were unilaterally abnormal in six children (26.1%) and bilaterally abnormal in five others (21.7%). Additionally, five of the children with an abnormal HIT had abnormalities, as found in the questionnaire results. Conclusion and Relevance: Almost half of the children observed after having undergone gentamicin therapy as newborns showed abnormalities in VHIT, although they did not show any clinical signs of disbalance or vestibular hypofunction. VHIT can serve as a sensitive investigation method for the early screening of post-therapeutic vestibulotoxic side effects after gentamicin therapy in children. Additionally, VHIT can enable early intervention in these children.

Taybeh EO, Naser AY. Hospital Admission Profile Related to Inner Ear Diseases in England and Wales. Healthcare (Basel) 2023; 11:healthcare11101457. [PMID: 37239743 DOI: 10.3390/healthcare11101457] [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: 02/06/2023] [Revised: 04/25/2023] [Accepted: 05/15/2023] [Indexed: 05/28/2023] Open
Abstract
BACKGROUND Due to an expansion in the usage of medications (such as anticancer therapies), increased exposure to noise, and an increase in life expectancy, the prevalence of inner ear disease-related hearing loss is rising. Diseases of the inner ear are frequently accompanied by other conditions, such as chronic heart failure, systemic inflammation, arterial hypertension, and cerebrovascular disease. The aim of this study was to investigate the profile of hospital admissions linked to inner ear diseases in England and Wales. METHOD This was an ecological descriptive study using public medical databases in England and Wales. Diagnostic codes for diseases of the inner ear (H80-H83) were used to identify all hospital admissions. Between 1999 and 2020, the chi-squared test was used to assess the difference between the admission rates. RESULTS From 5704 in 1999 to 19,097 in 2020, the total annual number of hospital admissions increased by 234.8%, which corresponds to a 192.3% increase in the admission rate [from 10.94 (95% CI 10.66-11.22) in 1999 to 31.98 (95% CI 31.52-32.43) in 2020 per 100,000 people, p < 0.01]. "Disorders of vestibular function" and "other inner ear diseases" were the most frequent causes of hospital admissions due to inner ear diseases, accounting for 47.6% and 43.6%, respectively. The age range of 15 to 59 years accounted for 42.3% of all diseases of the inner ear hospital admissions. Around 59.6% of all admissions were made by females. The female admission rate increased by 210.1% (from 12.43 (95% CI 12.01-12.85) in 1999 to 38.54 (95% CI 37.84-39.24) in 2020 per 100,000 people). The male admission rate for diseases of the inner ear increased by 169.6% [from 9.37 (95% CI 9.00-9.75) in 1999 to 25.26 (95% CI 24.69-25.84) per 100,000 people] in 2020. CONCLUSION Inner ear disease admissions increased markedly in England and Wales during the past two decades. Females and the middle-aged population were at higher risk of being admitted for inner ear diseases. Further cohort studies are warranted to identify other risk factors and develop effective prevention strategies.

Int J Pediatr Otorhinolaryngol 2021; 151:110921.

Abstract
INTRODUCTION The incidence of vestibular disorders and vertigo during childhood is increasing and pediatric clinicians have become more sensitive to children's balance disorders; thus, there is a need for appropriate detection test procedures for peripheral vestibular hypofunction. In order to ensure a reliable diagnosis and minimize misdiagnosis, a standardized clinical procedure via careful history and clinical examination is recommended. However, children, especially, are often unable to verbalize "vertigo" in a concrete manner, which often necessitates a consultation with a pediatrician holding nonspecific symptoms. The so-called suppression of the head impulse test (SHIMPs) represents a modification of the video head impulse test (HIMP) and is used for a more sensitive assessment of residual vestibular functions. In adults, SHIMPs are already an established diagnostic method. Nevertheless, to date, nothing is known about the applicability and standard values in childhood. MATERIAL AND METHODS In this monocentric, prospective study, we investigated whether SHIMPs enable a sensitive functional analysis of the vestibular system in healthy children of different ages. For this purpose, SHIMPs were performed in 40 children aged 3-18 years. RESULTS In this study, we demonstrated that SHIMPs can be easily performed in children (3-18 years). It is vital that the test be appropriately explained for children to ensure sufficient test tolerance and compliance. CONCLUSION SHIMPs are a helpful supplement to clinically established vestibular tests such as the HIMP in pediatric vestibular balance disorder diagnostics and can be integrated into the clinical routine, especially in children who have minimal verbal abilities or understanding of the instructions for HIMP. Similar to the HIMP, SHIMPs are characterized by a short test duration and a high tolerance.

Relevance of Artifact Removal and Number of Stimuli for Video Head Impulse Test Examination. Ear Hear 2021; 41:1397-1406. [PMID: 32058350 DOI: 10.1097/aud.0000000000000849] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To evaluate the effect of artifacts on the impulse and response recordings with the video head impulse test (VHIT) and determine how many stimuli are necessary for obtaining acceptably efficient measurements. METHODS One hundred fifty patients were examined using VHIT and their registries searched for artifacts. We compared several variations of the dataset. The first variation used only samples without artifacts, the second used all samples (with and without artifacts), and the rest used only samples with each type of artifact. We calculated the relative efficiency (RE) of evaluating an increasingly large number of samples (3 to 19 per side) when compared with the complete sample (20 impulses per side). RESULTS Overshoot was associated with significantly higher speed (p = 0.005), higher duration (p < 0.001) and lower amplitude of the impulses (p = 0.002), and consequent higher saccades' latency (p = 0.035) and lower amplitude (p = 0.025). Loss of track was associated with lower gain (p = 0.035). Blink was associated with a higher number of saccades (p < 0.001), and wrong way was associated with lower saccade latency (p = 0.012). The coefficient of quartile deviation escalated as the number of artifacts of any type rose, indicating an increment of variability. Overshoot increased the probability of the impulse to lay on the outlier range for gain and peak speed. Blink did so for the number of saccades, and wrong way for the saccade amplitude and speed. RE reached a tolerable level of 1.1 at 7 to 10 impulses for all measurements except the PR score. CONCLUSIONS Our results suggest the necessity of removing artifacts after collecting VHIT samples to improve the accuracy and precision of results. Ten impulses are sufficient for achieving acceptable RE for all measurements except the PR score.

Abstract
OBJECTIVE The clinical features and incidence of benign paroxysmal positional vertigo (BPPV) are not well known in pediatric populations. The aim of this study was to describe the clinical characteristics of pediatric BPPV and to estimate the frequency of pediatric BPPV in the general population. METHODS We retrospectively reviewed the medical records of 20 children (6-14 years old) diagnosed with BPPV between 2007 and 2017. The age/sex distribution of BPPV for all ages at our hospital and in the Korean Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS) database were compared. The annual incidence and proportion of children with BPPV were calculated. RESULTS BPPV occurred 1.86 times more frequently in girls than in boys. Nine children (45%) had associated comorbidities, such as inner ear disorders and recent head trauma. The posterior and lateral semicircular canals were most commonly involved (n = 9 for each), and recurrence was observed in two patients (10%). Children younger than 15 years accounted for approximately 1% of all BPPV cases. The annual incidence of BPPV was 171.5/100,000 for all ages and 9.5/100,000 in the pediatric population. CONCLUSIONS Our findings suggest that pediatric BPPV is a relatively uncommon cause of vertigo in children and that the rates of related illness and recurrence are high.

Abstract
ABSTRACT Purpose: to identify and analyze the available evidence on the reference values of the vestibulo-ocular reflex gain obtained with the video head impulse test. Methods: an integrative review based on the PRISMA protocol, searching the ProQuest, EBSCO, PubMed, ScienceDirect, Cochrane Library, LILACS, and SciELO databases with keywords. The studies included were original research articles, systematic reviews, and meta-analyses published since 2009, involving humans, written in English, Spanish and/or Portuguese. Results: 10,250 studies related to the keywords were found. Of these, 10 articles met the inclusion criteria and were analyzed following the CADE protocol. On the horizontal plane, the values ranged from 0.80 to 1.06, while on the right anterior/left posterior and on the left anterior/right posterior planes, the values ranged from 0.80 to 1.03. Other relevant data for obtaining the gain were analyzed, such as the number of impulses, the assessor’s experience, the patient-object distance, and the percentage of asymmetry. Conclusion: little research on the theme, recently developed and published, mostly in European countries, was found. This shows the need for a greater number of studies to strengthen the scientific evidence.

Abstract
OBJECTIVES The video-Head-Impulse-Test (vHIT) is widely used to evaluate vestibular function. Nevertheless, there is no consensus on the necessary or ideal number of impulses performed for robust VOR gains. Therefore, the aim of our study is to analyze how many impulses are needed to receive reliable VOR gains in difficult testing situations like testing children younger than 48 months and in children with vestibular loss. METHODS A retrospective data analysis was performed in which existing vHIT results of 25 healthy children aged 5-48 months were included as well as vHIT results of 25 children with vestibular loss aged 2-16 years. Descriptive data analysis was performed and further statistical analysis was conducted to determine if the number of head impulses could be reduced using internal consistency (Cronbach's alpha) and paired t-test. RESULTS Median gain was 0.95 (±0.16) for impulses to the right and 0.97 (±0.16) for impulses to the left in healthy children and ranged from 0.01 (±0.11) to 0.75 (+/- 0.23) in children with vestibular hypfunction. Analyzing Cronbach's Alpha, a 99.6% (α = 0.996) true score variance was achieved when two impulses were performed to the right and 98,1% to the left in healthy children and 99.9% in children with impaired vestibular function. CONCLUSION These results indicate that two high velocity artifact-free impulses from an experienced tester are sufficient to evaluate vestibular function in difficult vHIT testing conditions like testing very young children. Further impulses do not improve test reliability.
