Objectives: Tinnitus is a phantom sound sensation without an external sound source. Due to its subjective and multifaceted nature it is measured using multi-item self-reported instruments. Many well-validated tinnitus-related questionnaires are available for clinical practice and scientific research, but so far no attention has been paid to their measurement invariance. The study aimed to examine measurement invariance of the Tinnitus Handicap Inventory with regard to gender and hearing impairment, and to identify the items that show differential item functioning (DIF) across the groups. Design: This is a retrospective study using medical data from patients with tinnitus. They completed the Tinnitus Handicap Inventory (THI) and underwent pure-tone audiometry. Study sample: 1106 adult patients with tinnitus (554 women and 552 men; 320 with normal hearing and 786 with hearing loss), aged 19–84 years. Results: In the analysis, multi-group confirmatory factor analysis, hybrid ordinal logistic regression, Kernel smoothing in Item Response Theory, and lasso regression were applied. Measurement invariance was demonstrated across gender, but across hearing status the measurement was non-invariant. Five items were found to have DIF. Conclusions: Researchers and clinicians should be aware of the potential risk of response bias when tinnitus severity is evaluated. [ABSTRACT FROM AUTHOR]

Introduction: Frequently, bone conduction hearing aids on a softband are not tolerated by children due to pressure on the head or visual esthetics. By way of contrast, a non-surgical hearing system - Adhear (Med-El, Innsbruck, Austria) - allows the sound processor to be attached using a noninvasive adhesive adapter. The objective of this study was to evaluate the effectiveness of the Adhear system and assess its subjective benefits in a child who had bilateral conductive hearing loss. Case report: The Adhear system was tested in a 13-year-old child with bilateral conductive hearing loss. Pure tone audiometry and speech audiometry in quiet were performed without and then with a pair of devices placed bilaterally. Word recognition scores (WRS) at 50 and 65 dB SPL in quiet were measured using the Pruszewicz monosyllabic Polish word test. After 4 weeks, subjective hearing benefit and experience with the Adhear system was done using the APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire. Results: With Adhear, WRS at 50dB SPL increased significantly from an unaided score of 10% to 80%. The result of free-field audiometry with Adhear on both sides indicated a hearing level within the normal range. Conclusions: Adhear is an effective rehabilitation option for children with bilateral conductive hearing loss. [ABSTRACT FROM AUTHOR]

Introduction: This systematic review investigates the influence of adenotonsillectomy (AT) on asthma control in pediatric patients. Material and methods: A literature review from 2000 to 2023 based on the databases PubMed, the Cochrane Library, and Web of Science. The analysis is distilled down to four studies that revealed positive outcomes in asthma control as gauged by the Asthma Control Test (ACT), the Childhood Asthma Control Test (C-ACT), clinical outcomes, and asthma-related chitinase levels. Results: The four studies consistently demonstrated improved asthma control postoperatively in terms of improved ACT scores, reductions in acute asthma exacerbations, emergency room visits, hospitalisations, and medication usage. Notably, the correlation between improved asthma control and decreased chitinase activity suggests that AT has an impact on molecular markers associated with asthma. Conclusions: The findings underline the potential benefits of AT in pediatric asthma management. However, the limitations of this study include a small number of studies and potential biases related to asthma's natural course and seasonal variations. While the review provides evidence for the positive impact of AT on asthma control, further research with longer follow-up periods, case-matched controls, and consideration of seasonal factors is recommended.

The aim of this interventional non-randomised prospective controlled study was to assess the effectiveness of transcutaneous vagus nerve stimulation (tVNS) in human subjects with tinnitus. The ParasymTM tVNS device was paired with an auditory stimulation. Treatment and observations were conducted over 12 weeks. Audiological evaluation was performed. Responses from a set of questionnaires and quantitative electroencephalography (qEEG) before and after treatment were collected. Voice measurements were done to assess possible side-effects of tVNS. The study involved 29 adults who had chronic tinnitus (15 patients who underwent tVNS paired with sounds and a control group of 14 patients who did not). In general, subjective and objective measurements of tinnitus showed no improvement in the study group compared to the controls, although certain parameters as gauged by the questionnaires did statistically improve. The loudness and frequency of tinnitus remained the same in both groups. For the qEEG, activity in the theta band increased significantly in the study group compared to the control group. The tVNS was not effective in reducing tinnitus symptoms in our study group. However, changes in the theta band suggest there might be cortical effects that might, with sustained treatment, lead to improvements. [ABSTRACT FROM AUTHOR]

BACKGROUND: The aim was to assess the hearing outcomes in cochlear implant patients with far-advanced otosclerosis who had previously undergone stapes surgery. METHODS: We studied 17 implanted patients with far-advanced otosclerosis who had previously undergone stapes surgery. They comprised 15 women and 2 men, aged 37-73 years; the duration of hearing impairment was 9-42 years. Pure-tone audiometry (0.125-8 kHz) was performed preoperatively and at 1, 6, and 12 months postoperatively. Free-field speech audiometry was conducted before and 12 months after surgery, and word recognition scores were assessed. RESULTS: Average preoperative hearing thresholds were 108 dB HL for air conduction and were at the limit of the audiometer for bone conduction. Word recognition scores before surgery averaged 7.4% (at 70 dB) and increased significantly to 66.2% about 12 months after surgery. Adverse surgical events were rare. CONCLUSION: Patients with far-advanced otosclerosis and who have previously undergone stapes surgery are likely to experience a deterioration in hearing and receive insufficient benefits from hearing aids. Cochlear implantation can improve their hearing and provide good speech understanding. [ABSTRACT FROM AUTHOR]

This study looked at the possible effect of the COVID-19 pandemic on individuals who came to our clinic seeking relief from tinnitus. The performance of the subjects during the COVID-19 pandemic was compared with similar individuals who came to our clinic before the pandemic began. The study involved 50 adults with chronic tinnitus, made up of a study group (24 subjects tested during the COVID-19 pandemic of 2020–2021) and a control group before the pandemic began (26 subjects tested from 2013 to 2017). None of the 24 reported having contracted COVID-19. Data collection involved the Tinnitus Handicap Inventory (THI) questionnaire, audiological tests, and quantitative electroencephalography (qEEG). In terms of THI scores, there were no statistically significant differences between the two groups. However, with regard to qEEG, some changes were observed, with significant decreases in alpha and beta band activity in the study group compared to the control group, particularly over the auditory cortex. We conclude that COVID-19 did not have a discernible impact on the general well-being of individuals with tinnitus. However, it did appear to alter brain activity, specifically in the alpha and beta bands over the auditory cortex, and these reults warrant further investigation. [ABSTRACT FROM AUTHOR]

Introduction: The electrode length is one of the many factors impacted on results of cochlear implantation. Among lateral wall flexible electrode arrays the latest one is FLEX26 (MED-EL GmbH, Innsbruck, Austria). The main aim of the study was to evaluate the preservation of residual hearing, the level of speech understanding, and quality of life after cochlear implantation with FLEX26 electrode array. Methods: The study was conducted in a tertiary referral centre. Fifty-two patients implanted unilaterally with FLEX26, including 10 EAS patients (electric acoustic stimulation) and 42 ES patients (electric stimulation). The intervention was minimally invasive cochlear implantation via the round window. Pure-tone audiometry (0.125–8 kHz) was performed preoperatively and at 1, 6, and 12 months postoperatively. Twelve-month hearing preservation was established using HEARRING group formula. Quality of life was measured with AQoL-8D (Assessment of Quality of Life–8 Dimensions) pre- and postoperatively. Results: Residual hearing was preserved in 88.8% EAS patients. Quality of life was significantly better postoperatively in comparison to preoperative period (the effect size for overall quality of life was 0.49). Especially, it increased in relationships and senses dimensions (the effect sizes 0.47 and 0.44, respectively). Conclusion: Preservation of residual hearing can be achieved in the majority of patients implanted with FLEX26. Improvement of quality of life was also documented. FLEX26 seems to be an option for surgeons who seek an electrode providing sufficient cochlear coverage. [ABSTRACT FROM AUTHOR]
