Demographic analysis of hearing impairment based on various parameters in patients with cochlear implant.

Objectives: To analyse the demographic and clinical variables in children having undergone cochlear implant surgery because of deafness. METHODS: The cross-sectional study was conducted from January to November 2022 at the Centre for Research in Experimental and Applied Medicine laboratory of the Department of Biochemistry and Molecular Biology, Army Medical College, Rawalpindi, Pakistan, in collaboration with the Ear, Nose and Throat Department of Combined Military Hospital, Rawalpindi, and comprised children of eith gender aged up to 10 years who had received cochlear implant. Data was collected through questionnaire-based detailed interviews. Syndromic Hearing Loss, Non-Syndromic Hearing Loss, and Acquired Hearing Loss were identified among the subjects. Data was analysed using SPSS 22. RESULTS: Of the 250 cases, 147(58.8%) were boys, 146(58.4%) were aged 0-5 years, 219(87.6%) had prelingual onset of disease, and 202(80.8%) had a non-progressive disease course. In 203(81.2%) cases, normal developmental milestones were seen. Parental consanguinity was observed in 219(87.6%) cases. However, 63(25.2%) patients had a first-degree relative who had a history of deafness. In 170(68%) cases, hearing loss was hereditary, whereas in 80(32%) it was acquired. Meningitis was the most commonly identified risk factor 55(68.75%). Acquired risk factors and family history had significant association with hearing loss (p<0.05). Speech perception significantly improved in all 219(100%) patients with prelingual hearing loss who underwent cochlear implantation. CONCLUSIONS: Majority of the cases were found to be male, had a prelingual disease onset and a non-progressive disease course. Family history was a significant factor, while meningitis was the most common acquired cause of hearing loss.

Chronological change of left ventricular global longitudinal strain in patients with maternally inherited diabetes and deafness: A case series.

RATIONALE: Maternally inherited diabetes and deafness (MIDD) is a rare genetic disorder arising from mitochondrial DNA mutations, characterized by a combination of diabetes mellitus and sensorineural deafness. It is known that MIDD patients with cardiomyopathy have a poor prognosis, but there are no established guidelines for the diagnosis and follow-up of cardiomyopathy in MIDD patients. PATIENT CONCERNS: Patient 1 was a 48-year-old woman who visited the hospital with cardiomegaly and had been taking oral hypoglycemic agents for 8 years. Patient 2 was a 21-year-old man, the son of patient 1, who visited the hospital for genetic screening. Patient 2 was also diagnosed diabetes mellitus 2 years ago. DIAGNOSIS: Patient 1 was found to have restrictive cardiomyopathy on echocardiography and underwent endomyocardial biopsy and genetic testing to determine the etiology. The m.3243A>G mutation was confirmed and she was diagnosed with MIDD accompanied with diabetes and hearing loss. Additionally, patient 2 had m.3243 A>G mutation and was diagnosed with MIDD due to diabetes and hearing loss. INTERVENTIONS: Because MIDD does not have a specific treatment, patient 1 took ubidecarenone (coenzyme Q10), acetylcarnitine, and multivitamin along with the treatment for diabetes control and heart failure. Patient 2 was taking ubidecarenone (coenzyme Q10), acetylcarnitine, and multivitamin along with treatment for diabetes. OUTCOMES: She subsequently underwent routine transthoracic echocardiography, and a progressive decline in global longitudinal strain (GLS) was first observed, followed by a worsening of the patient's clinical situation. Patient 2 had concentric remodeling and decreased GLS. On periodic echocardiography, GLS decreased at a very slow rate, and the patient's clinical course was stable. LESSONS: The findings of this report contribute to the understanding of the clinical course of MIDD-associated cardiomyopathy and highlight the potential of GLS as a sensitive marker for disease progression.

Hearing Loss, Hearing Aid Use, and Risk of Dementia in Older Adults.

Importance: Hearing loss has been suggested as a risk factor for dementia, but there is still a need for high-quality research to better understand the association between these 2 conditions and the underlying causal mechanisms and treatment benefits using larger cohorts and detailed data. Objective: To investigate the association between hearing loss and incident dementia, as well as how hearing aid use contributes to this association. Design, Setting, and Participants: This population-based cohort study was conducted in Southern Denmark between January 2003 and December 2017 and included all residents 50 years and older. We excluded all persons with dementia before baseline as well as those who did not live in the region 5 years before baseline, with incomplete address history, or who had missing covariate information. Exposures: Individual hearing status based on the Hearing Examinations in Southern Denmark database, which contains data on all pure-tone audiometry examinations performed at public hearing rehabilitation clinics in Southern Denmark. Main Outcomes and Measures: Incident cases of dementia and Alzheimer disease as identified from national registries. Results: The study population comprised 573 088 persons (298 006 women [52%]; mean [SD] age, 60.8 [11.3] years) with 23 023 cases of dementia and mean (SD) follow-up of 8.6 (4.3) years. Having a hearing loss was associated with an increased risk of dementia, with an adjusted hazard ratio (HR) of 1.07 (95% CI, 1.04-1.11) compared with having no hearing loss. Severe hearing loss in the better and worse ear was associated with a higher dementia risk, with an HR of 1.20 (95% CI, 1.09-1.32) and 1.13 (95% CI, 1.06-1.20), respectively, compared with having no hearing loss in the corresponding ear. Compared with people without hearing loss, the risk of dementia was higher among people with hearing loss who were not using hearing aids than those who had hearing loss and were using hearing aids, with HRs of 1.20 (95% CI, 1.13-1.27) and 1.06 (95% CI, 1.01-1.10), respectively. Conclusions and Relevance: The results of this cohort study suggest that hearing loss was associated with increased dementia risk, especially among people not using hearing aids, suggesting that hearing aids might prevent or delay the onset and progression of dementia. The risk estimates were lower than in previous studies, highlighting the need for more high-quality longitudinal studies.

Disease Manifestations and Complications in Dutch X-Linked Hypophosphatemia Patients.

X-linked hypophosphatemia (XLH) is the most common monogenetic cause of chronic hypophosphatemia, characterized by rickets and osteomalacia. Disease manifestations and treatment of XLH patients in the Netherlands are currently unknown. Characteristics of XLH patients participating in the Dutch observational registry for genetic hypophosphatemia and acquired renal phosphate wasting were analyzed. Eighty XLH patients, including 29 children, were included. Genetic testing, performed in 78.8% of patients, showed a PHEX mutation in 96.8%. Median (range) Z-score for height was - 2.5 (- 5.5; 1.0) in adults and - 1.4 (- 3.7; 1.0) in children. Many patients were overweight or obese: 64.3% of adults and 37.0% of children. All children received XLH-related medication e.g., active vitamin D, phosphate supplementation or burosumab, while 8 adults used no medication. Lower age at start of XLH-related treatment was associated with higher height at inclusion. Hearing loss was reported in 6.9% of children and 31.4% of adults. Knee deformities were observed in 75.0% of all patients and osteoarthritis in 51.0% of adult patients. Nephrocalcinosis was observed in 62.1% of children and 33.3% of adults. Earlier start of XLH-related treatment was associated with higher risk of nephrocalcinosis and detection at younger age. Hyperparathyroidism longer than six months was reported in 37.9% of children and 35.3% of adults. This nationwide study confirms the high prevalence of adiposity, hearing loss, bone deformities, osteoarthritis, nephrocalcinosis and hyperparathyroidism in Dutch XLH patients. Early start of XLH-related treatment appears to be beneficial for longitudinal growth but may increase development of nephrocalcinosis.

Granulomatosis with polyangiitis presenting headache: A case report and review of literature.

RATIONALE: Central nervous system involvement is a rare manifestation of active-phaselocalized Granulomatosis with polyangiitis (GPA). In hypertrophic dura meningitis, GPA with headache is typical. In this case, cerebral magnetic resonance (MR) enhancement revealed no meningeal thickening, to our knowledge, this manifestation had not been found previously. PATIENT CONCERNS: The patient presented to the Rheumatology and Immunology Clinic with severe headache and hearing loss, and central nervous system granulomatosis with polyangiitis was confirmed after a series of examinations. The patient had no significant effect after treatment with cyclophosphamide (CTX), but after the use of rituximab, the headache and hearing loss were significantly improved, and laboratory indicators returned to normal levels. DIAGNOSIS: We comprehensively screened for craniocerebral infection and malignant tumors, diagnosed central nervous system granulomatosis with polyangiitis. INTERVENTIONS: We gave sequential treatment of rituximab. OUTCOMES: All indicators are mostly back to normal when the patient was monitored at the outpatient clinic. LESSONS: GPA and severe headache are more prevalent in hypertrophic dura meningitis, but the patient early headache could not be explained by hypertrophic dura meningitis or localized granulomatous lesions that invaded the central nervous system. Patients with severe headaches likely have vascular inflammation and local bone destruction at the base of the skull.

Identifying Predictors of Treatment Response in Meniere's Disease: A Clinical Severity Staging System.

OBJECTIVE: Identify clinically important factors associated with conservative treatment response in Meniere's disease and incorporate these factors into a composite clinical severity staging system. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary academic medical center. METHODS: Adult patients newly diagnosed with Meniere's disease between January 1, 2016 and December 31, 2019 were eligible. Patients with previous treatment for Meniere's disease, prior otologic surgery, or a lack of follow-up data were excluded. Treatment-responsive patients were managed with only conservative therapies (eg, dietary modifications, diuretics) and unresponsive patients underwent more intensive therapies (eg, intratympanic procedures, surgical interventions). RESULTS: Of 78 patients included in the study, 49 (63%) were responsive to conservative therapies and 29 (37%) were not. Responsive patients had higher proportions of no or mild vertigo (24%, 95% confidence interval [CI]: 3.1%-45.8%) and none or mild comorbidity (27%, 95% CI: 9.2%-44.7%) and a lower proportion of hearing loss (19%, 95% CI: 5.6%-32.4%) compared to unresponsive patients. Conjunctive consolidation of these 3 factors was performed to develop a three-stage system with a treatment response gradient ranging from 100% to 64% to 18% for stage 1 (n = 11), stage 2 (n = 56), and stage 3 (n = 11), respectively. CONCLUSIONS: This study identified decreased vertigo severity, reduced comorbidity burden, and absence of hearing loss as factors associated with conservative treatment response in Meniere's disease. A composite clinical severity staging system including these 3 factors can be used to optimize treatment selection and promote patient-centered management of Meniere's disease.

The effect of anxiety and depression on cognition in older adults with severe-to-profound hearing loss.

PURPOSE: To evaluate the effect of anxiety and/or depression on cognition in older adults with severe-to-profound hearing loss. METHODOLOGY: In total, 83 older subjects (age of 55 years or older) with post-lingual, bilateral, severe-to-profound hearing loss were enrolled in this study between April 2014 and March 2021. The Repeatable Battery for Assessment of Neuropsychological Status for Hearing-impaired individuals (RBANS-H) and the Hospital Anxiety and Depression Scale (HADS) were used to measure cognition and anxiety/depression. RESULTS: A multiple linear regression was used to predict the total RBANS-H score based on the total HADS score, years of education and age of the participants. These variables statistically significantly predicted RBANS-H, F(3, 79) = 12.604, p = 0.010, R2 = 0.324. All three variables added statistically significantly to the prediction, p < 0.05. A higher HADS-score resulted in a significantly lower RBANS-H score with an estimated effect size b1 of - 0.486. In addition, a multiple linear regression was executed for each subdomain of the RBANS-H and its relation to the total HADS-score, age and years of education of the participants. These variables statistically significantly predicted RBANS-H immediate memory F(3, 79) = 16.858, p = 0.003, R2 = 0.390. All three variables added statistically significantly to the prediction, p < 0.05. In the other four subdomains no statistical significance was observed. CONCLUSIONS: Anxiety and/or depression have a significantly negative impact on cognition in individuals with severe-to-profound hearing loss. This negative correlation was mainly attributable to the significantly lower score in the immediate memory subdomain.

Discovery of a Novel Missense Variant in NLRP3 Causing Atypical Cryopyrin-Associated Periodic Syndromes With Hearing Loss as the Primary Presentation, Responsive to Anti-Interleukin-1 Therapy.

OBJECTIVE: Cryopyrin-associated periodic syndromes (CAPS), also known as NLRP3-associated autoinflammatory diseases, are a spectrum of rare autoinflammatory diseases caused by gain-of-function variants in the NLRP3 gene, resulting in inflammasome hyperactivation and dysregulated release of interleukin-1ß (IL-1ß). Many patients with CAPS develop progressive sensorineural hearing loss (SNHL) because of cochlear autoinflammation, which may be the sole manifestation in rare cases. This study was undertaken to establish the suspected diagnosis of CAPS in a family presenting with autosomal-dominant progressive/acute SNHL and a novel missense variant in the NLRP3 gene of unknown significance (NM_001079821.3:c.1784G>A p.Ser595Asn). METHODS: We conducted an ex vivo functional assessment of the NLRP3 inflammasome in heterozygous individuals (n = 10) and healthy family members (n = 5). RESULTS: The assay revealed hyperactivation of the inflammasome among heterozygous individuals, supporting the hypothesis that this missense variant is a pathogenic gain-of-function variant. Administration of IL-1 receptor antagonist resulted in a substantial clinical improvement among pediatric patients, who exhibited near resolution of hearing impairment within 1 to 3 months of treatment. CONCLUSION: Our findings highlight the crucial role of early diagnosis and treatment with an anti-IL-1 agent in reversing cochlear damage. Furthermore, our results suggest that high- and ultrahigh-frequency ranges need to be included in the auditory assessment to enable early detection of subclinical SNHL. Finally, incorporating functional inflammasome assessment as part of the clinical evaluation could establish the diagnosis in inconclusive cases.

Neuroimaging in infants with congenital cytomegalovirus infection and its correlation with outcome: emphasis on white matter abnormalities.

OBJECTIVE: To evaluate the association between neuroimaging and outcome in infants with congenital cytomegalovirus (cCMV), focusing on qualitative MRI and quantitative diffusion-weighted imaging of white matter abnormalities (WMAs). METHODS: Multicentre retrospective cohort study of 160 infants with cCMV (103 symptomatic). A four-grade neuroimaging scoring system was applied to cranial ultrasonography and MRI acquired at ≤3 months. WMAs were categorised as multifocal or diffuse. Temporal-pole WMAs (TPWMAs) consisted of swollen or cystic appearance. Apparent diffusion coefficient (ADC) values were obtained from frontal, parieto-occipital and temporal white matter regions. Available follow-up MRI at ≥6 months (N=14) was additionally reviewed. Neurodevelopmental assessment included motor function, cognition, behaviour, hearing, vision and epilepsy. Adverse outcome was defined as death or moderate/severe disability. RESULTS: Neuroimaging scoring was associated with outcome (p<0.001, area under the curve 0.89±0.03). Isolated WMAs (IWMAs) were present in 61 infants, and WMAs associated with other lesions in 30. Although TPWMAs and diffuse pattern often coexisted in infants with IWMAs (p<0.001), only TPWMAs were associated with adverse outcomes (OR 7.8; 95% CI 1.4 to 42.8), including severe hearing loss in 20% and hearing loss combined with other moderate/severe disabilities in 15%. Increased ADC values were associated with higher neuroimaging scores, WMAs based on visual assessment and IWMAs with TPWMAs. ADC values were not associated with outcome in infants with IWMAs. Findings suggestive of progression of WMAs on follow-up MRI included gliosis and malacia. CONCLUSIONS: Categorisation of neuroimaging severity correlates with outcome in cCMV. In infants with IWMAs, TPWMAs provide a guide to prognosis.

HDR syndrome, detected in the neonatal period by newborn hearing screening.

Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome is an autosomal dominant disorder. Because HDR syndrome is caused by haploinsufficiency in GATA3, it exhibits variation in the onset and progression of hearing loss. In previous reports, the automated auditory brainstem response (AABR) was considered insufficient to detect sensorineural hearing loss caused by HDR syndrome. We report a case of HDR syndrome whose congenital hearing loss was detected by newborn hearing screening (NHS) using AABR. In this case, HDR syndrome was suspected due to hearing loss, hypocalcemia, and her family history. Genetic testing confirmed the diagnosis of HDR syndrome at 5 months of age. Because the phenotype of hearing loss due to HDR syndrome is variable and includes progressive hearing loss, these cases may not be detected by the HNS. However, most of the previous reports were published before the NHS became common and given the frequency of hearing loss complications in HDR syndrome. We consider that there is a reasonable number of HDR syndrome cases with abnormalities on the NHS. We believe that the NHS may also be useful for early detection of hearing loss due to HDR syndrome.

Diagnosis and management of facial nerve palsy secondary to granulomatosis with polyangiitis - A systematic review.

OBJECTIVE: Granulomatosis with polyangiitis is associated with otolaryngologic complaints in 70-95 % of cases, with the most common being serous otitis media. In rare cases, patients may experience facial nerve palsy in conjunction with otologic or nasal symptoms; and, often, initially present to an otolaryngologist. It is important for healthcare professionals to be able to recognize the nuisances of facial nerve palsy as a potential presentation of granulomatosis with polyangiitis. STUDY DESIGN: Systematic review. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Protocol, PubMed and MED-LINE Databases were queried for articles published from January 2007 to December 2022 describing facial nerve palsy in the context of Granulomatosis with polyangiitis, formerly known as Wegener's Granulomatosis. The keywords included "facial nerve palsy", "facial palsy", "granulomatosis with polyangiitis", "Wegener's granulomatosis", "ANCA positive" in the title/abstract. All full-text articles available in English were screened, including single case presentations. Abstracts, commentaries, and publications deemed outside the scope of our study aims were excluded from review. After removal of duplicate articles, a total of 85 articles were screened. After applying inclusion and exclusion criteria, 14 articles were included in the review. RESULTS: There were a total of 28 reports of facial nerve palsy in the literature in patients who were eventually diagnosed with granulomatosis with polyangiitis. The patients' ages ranged from 14 to 68 years old. None of the patients had been previously diagnosed with GPA, and a majority of them presented initially with other otologic symptoms. Hearing loss was reported in 24 patients (86 %), otalgia was present in 11 patients (39 %), and otorrhea was present in 6 patients (21 %). Bilateral facial paralysis was reported in 10 patients in the literature (36 %). In total, 16 patients underwent surgery for facial paralysis: 6 tympanomastoidectomies, 4 mastoidectomies, 2 explorative tympanotomies. Surgery was generally considered ineffective in resolving facial weakness. All patients ended up receiving some combination of steroids and immunosuppressant, most commonly prednisolone and cyclophosphamide or rituximab, which was eventually transitioned to azathioprine for maintenance. Unlike auditory thresholds, which remained decreased in two patients, all patients recovered facial function following appropriate medical treatment of their vasculitis. CONCLUSIONS: Facial nerve paralysis in patients with granulomatosis with polyangiitis is a rare but treatable phenomenon. In patients with intractable otitis media, unresolving facial palsy, or a combination of otologic issues, it is important to consider GPA as a possible source. The prognosis for facial function appears to be excellent in patients who undergo appropriate treatment for vasculitis, but further studies are needed for confirmation.

Risk Factors for Natural Hearing Evolution in Newborns With Congenital Cytomegalovirus Infection.

Importance: Congenital cytomegalovirus (cCMV) is the major cause of congenital nonhereditary sensorineural hearing loss in children. Currently, criteria to identify infants at increased risk for unfavorable hearing outcome are lacking. Objective: To identify risk factors associated with cCMV-related hearing improvement, hearing deterioration, and late-onset hearing loss. Design, Setting, and Participants: This multicenter cohort study included patients from 6 secondary and tertiary hospitals enrolled in the Flemish CMV registry (Belgium). Newborns with untreated cCMV infection with at least 4-year audiological follow-up were included. Patients who presented with other possible causes of sensorineural hearing loss were excluded. Data were collected for 15 years (January 1, 2007, to February 7, 2022) and analyzed from September 26, 2022, to January 16, 2023. Main Outcomes and Measures: Primary outcome was hearing evolution (per-ear analysis; described as stable hearing, improvement, or deterioration). The association of gestational characteristics, clinical findings, timing of seroconversion, viral load, and hearing status at birth with hearing evolution was investigated using effect sizes (Cramer V, odds ratio [OR], or Hedges g). Results: Of the 387 children, 205 of 385 with nonmissing data were male (53.2%), 113 (29.2%) had a symptomatic infection, and 274 (70.8%) had an asymptomatic infection. Every child was 4 years or older at final hearing evaluation. A total of 701 of 774 ears (90%) showed stable hearing (normal hearing or stable hearing loss since birth) over time. Late-onset hearing loss (normal hearing at birth followed by hearing loss) was present in 43 of 683 ears (6.3%). Among children with hearing loss present at birth, 24 of 34 ears (70.6%) had hearing deterioration, and 6 of 91 ears (6.6%) had hearing improvement. Prematurity was associated with a higher chance of hearing improvement (OR, 12.80; 95% CI, 2.03-80.68). Late-onset hearing loss was more prevalent in a first trimester infection (OR, 10.10; 95% CI, 2.90-34.48). None of the 104 ears of children with a third trimester seroconversion developed late-onset hearing loss. Conclusions and Relevance: Findings of this cohort study support that ongoing audiological follow-up for untreated children with congenital hearing loss is important, as the majority of patients had hearing deterioration. The timing of seroconversion was associated with the risk of developing late-onset hearing loss. These insights can aid in parental counseling, patient stratification, and follow-up. Future research should focus on the effect of treatment, the influence of determined risk factors, and the study of eventual new risk factors in patients at high risk to develop hearing loss.

Risk Factors for Young-Onset Dementia in the UK Biobank.

Importance: There is limited information on modifiable risk factors for young-onset dementia (YOD). Objective: To examine factors that are associated with the incidence of YOD. Design, Setting, and Participants: This prospective cohort study used data from the UK Biobank, with baseline assessment between 2006 and 2010 and follow-up until March 31, 2021, for England and Scotland, and February 28, 2018, for Wales. Participants younger than 65 years and without a dementia diagnosis at baseline assessment were included in this study. Participants who were 65 years and older and those with dementia at baseline were excluded. Data were analyzed from May 2022 to April 2023. Exposures: A total of 39 potential risk factors were identified from systematic reviews of late-onset dementia and YOD risk factors and grouped into domains of sociodemographic factors (education, socioeconomic status, and sex), genetic factors (apolipoprotein E), lifestyle factors (physical activity, alcohol use, alcohol use disorder, smoking, diet, cognitive activity, social isolation, and marriage), environmental factors (nitrogen oxide, particulate matter, pesticide, and diesel), blood marker factors (vitamin D, C-reactive protein, estimated glomerular filtration rate function, and albumin), cardiometabolic factors (stroke, hypertension, diabetes, hypoglycemia, heart disease, atrial fibrillation, and aspirin use), psychiatric factors (depression, anxiety, benzodiazepine use, delirium, and sleep problems), and other factors (traumatic brain injury, rheumatoid arthritis, thyroid dysfunction, hearing impairment, and handgrip strength). Main Outcome and Measures: Multivariable Cox proportional hazards regression was used to study the association between the risk factors and incidence of YOD. Factors were tested stepwise first within domains and then across domains. Results: Of 356 052 included participants, 197 036 (55.3%) were women, and the mean (SD) age at baseline was 54.6 (7.0) years. During 2 891 409 person-years of follow-up, 485 incident YOD cases (251 of 485 men [51.8%]) were observed, yielding an incidence rate of 16.8 per 100 000 person-years (95% CI, 15.4-18.3). In the final model, 15 factors were significantly associated with a higher YOD risk, namely lower formal education, lower socioeconomic status, carrying 2 apolipoprotein ε4 allele, no alcohol use, alcohol use disorder, social isolation, vitamin D deficiency, high C-reactive protein levels, lower handgrip strength, hearing impairment, orthostatic hypotension, stroke, diabetes, heart disease, and depression. Conclusions and Relevance: In this study, several factors, mostly modifiable, were associated with a higher risk of YOD. These modifiable risk factors should be incorporated in future dementia prevention initiatives and raise new therapeutic possibilities for YOD.

Response to OKN-007 and NAC in a Patient with Unilateral Hearing Loss and Chronic Tinnitus from Vestibular Schwannoma.

BACKGROUND: Tinnitus is the perception of sound in the absence of external acoustic stimulation. Being one of the most common diseases of the ear, it has a global prevalence ranging from 4.1 to 37.2%. To date, it has been difficult to treat tinnitus as its pathophysiology is poorly understood and there are limited treatment options. OBJECTIVE: To investigate the effect of OKN-007 (also known as HPN-07), a nitrone-based investigational drug, in combination with oral N-acetylcycsteine (NAC), for the treatment of hearing loss and chronic tinnitus under an individual expanded access protocol. PATIENT CASE: We report the case of a patient who presented with left-sided ear fullness, mild tinnitus, and mild high frequency sensorineural hearing loss with 100% word recognition. A large enhancing mass seen on MRI revealed a vestibular schwannoma. He underwent subtotal resection of the tumor resulting in a moderate-to-profound sensorineural hearing loss and catastrophic tinnitus. The patient was treated with intravenous OKN-007 at 60 mg/kg dosed three times per week and oral NAC 2500 mg twice daily. RESULTS: Post-treatment audiometric testing revealed an average of 16.66 dB in hearing threshold improvement in three frequencies (125, 250 and 500 Hz) with residual hearing in the affected left ear. His tinnitus loudness matching improved from 90 dB to 19 dB post-treatment. His Tinnitus Handicap Inventory improved from 86/100 (Catastrophic) to 40/100 (Moderate). He also experienced improvements in sleep, concentration, hearing, and emotional well-being, and reported significantly decreased levels of tinnitusrelated distress. CONCLUSIONS: This case report highlights the feasibility and therapeutic potential of the combination of OKN-007 and NAC in treating hearing loss and tinnitus that warrants further investigation.

COX inhibitor use during definitive radiotherapy is associated with worse hearing preservation in patients with vestibular schwannoma.

PURPOSE: Patients with vestibular schwannoma undergoing definitive radiotherapy commonly experience hearing loss due to tumor and treatment effects; however, there is limited data evaluating concurrent medication use and other clinicopathologic factors associated with hearing preservation during and after radiotherapy. We performed a retrospective cohort study reviewing consecutive patients from 2004 to 2019 treated with radiotherapy for vestibular schwannoma at our institution. METHODS: Ninety four patients with concurrent medications, baseline audiograms, and post-radiotherapy audiograms available were evaluable. We performed chi-squared analyses of the frequency of various clinicopathologic factors and t-tests evaluating the degree of hearing loss based on audiograms. RESULTS: At a median follow-up of 35.7 months (mean: 46.5 months), the baseline pure-tone average (PTA) of the ipsilateral ear worsened from 38.4 to 59.5 dB following completion of radiotherapy (difference: 21.1, 95% CI 17.8-24.4 dB, p < 0.001). 36 patients (38.3%) reported regular use of cyclooxygenase (COX) inhibitors (including acetaminophen and NSAIDs) during radiotherapy. The mean increase in PTA was significantly higher for patients taking COX inhibitors (25.8 dB vs 18.1 dB, p = 0.024) in the ipsilateral ear but not for the contralateral side. COX inhibitor use remained independently associated with worse PTA in the multivariate analysis. CONCLUSION: COX inhibitor use during definitive radiotherapy is associated with worse hearing loss in the affected ear but not for the contralateral side. This suggests the ototoxic effects of COX inhibitors may influence the effects of radiotherapy. These results could have clinical implications and warrant further investigation.

Association between severe preoperative hearing impairment and postoperative emergence agitation among elderly patients undergoing middle ear surgery.

BACKGROUND: Hearing impairment is an established independent risk factor for delirium.Whether preoperative hearing impairment is associated with postoperative emergence agitation (POEA) in elderly patients remains unknown. This study aimed to investigate the association between preoperative hearing impairment and POEA in elderly patients undergoing ear surgery. METHODS: This prospective observational study was carried out at an otologic centre in a tertiary hospital between July 15, 2020, and February 28, 2021. Data of 417 elderly patients who underwent microscopic and endoscopic middle ear surgery were analyzed. Pure tone average was used to assess preoperative hearing function, with a PTA ≥ 50 dB indicating severe hearing impairment. POEA was measured using the Richmond Agitation-Sedation Scale. Multiple logistic regression was used to determine the association between preoperative hearing function and POEA. RESULTS: Of the 417 participants, 45.8% were men, and the median age was 64 (interquartile range: 62-67) years old. Severe preoperative hearing impairment was present in 113 patients (27.1%), and POEA occurred in 42 patients (10.1%). Multiple logistic regression analysis indicated that severe preoperative hearing impairment was associated with an increased risk of POEA (odds ratio: 2.031; 95% confidence interval: 1.044-3.954, P = 0.037). CONCLUSION: Pending confirmative studies, these findings suggest that severe preoperative hearing impairment could serve as an independent predictor of POEA in older patients undergoing middle ear surgery. These results highlight the need for further research to better understand the biomarker and pathogenesis of POEA, leading to identification of targeted interventions of POEA and improvement of postoperative outcomes in patients.

[Acromegaly in the differential diagnosis of hearing loss].

Acromegaly is a multifactorial neuroendocrine disease caused by hyperproduction of growth hormone (GH). In more than 95% of cases the reason of acromegaly the GH-secreting pituitary adenoma. In patients with this neuroendocrine disease, a slowly developing complex of symptom can manifest with concomitant pathological conditions, including auditory function disordersDiagnostic difficulties of acromegaly at the ambulatory stage determine the importance of doctor`s awareness in different medical specialties.Here we demonstrate a clinical case of the improvement of the auditory function due to combined surgical and medical treatment of a patient with the pituitary macroadenoma, acromegaly and hearing loss.Anamnesis features: a patient with an active stage of acromegaly and a pituitary macroadenoma measuring 57x35x32 mm with ante-, supra-, infra-, parasellar spread, (Knosp III(D), Knosp IV(S) noted a violation of auditory function. She was consulted by an otolaryngologist, sensorineural hearing loss on the right of the 3rd degree was diagnosed, on the left of the 1st degree. The patient underwent surgical treatment of pituitary adenoma, noted a significant improvement in auditory function in the early postoperative period. Six months later, repeated audiometry was performed, marked regression of hearing damage was noted.The case described by us indicates the reversibility of a rare complication of acromegaly - hearing loss and the importance of an interdisciplinary approach in the management of patients with this pathology.

Recent surgical advances and continued controversies in medically refractory Meniere's disease.

PURPOSE OF REVIEW: Meniere's disease is caused by hydropic changes in the endolymphatic system, and manifests as a collection of vertigo, hearing loss, tinnitus, and aural fullness. Although high-quality clinical practice guidelines exist for the diagnosis and initial management of Meniere's disease, there is no strong consensus for treatment of medically refractory Meniere's disease. This review summarizes treatment options and highlights controversies surrounding surgical treatment of Meniere's disease. RECENT FINDINGS: Intratympanic steroid and intratympanic gentamicin injections continue to be widely used as in-office therapies in medically refractory Meniere's disease. Despite historical controversy surrounding the use of endolymphatic sac (ELS) surgery, the use of ELS decompression has been widely adopted by the international neurotologic community due to high vertigo control rate, coupled with low risk of audiovestibular loss. Wider decompression of the sac and surgical manipulation of the endolymphatic duct may impact outcome and are the subject of discussion. An emerging surgical technique called Triple Semicircular Canal Occlusion (TSCO) holds promise as a partially ablative procedure with high vertigo control rate in Meniere's disease. Cochlear implants may be placed in active Meniere's disease patients, or during an ablative surgery such as labyrinthectomy. SUMMARY: For the medically refractory Meniere's disease patient, treatment options include intratympanic steroid injection, endolymphatic sac decompression, medical or surgical labyrinthectomy, and vestibular nerve section. TSCO holds promise as an emerging partially ablative procedure. Cochlear implants maintain an important role in the rehabilitation of hearing loss associated with Meniere's disease.

Correlation Between Laterality of Hearing Loss and Migraine Features in Menière's Disease.

OBJECTIVES: The objective of this study is to understand whether the hearing loss laterality in Menière's disease (MD) correlates with migraine symptoms laterality such as headache, neck stiffness, and otalgia. METHODS: We performed a retrospective review of prospectively obtained data on patients presenting between September 2015 and October 2021 with definite or probable MD. A custom-designed, comprehensive questionnaire was used to identify patients' migraine-related symptoms. The clinical and audiometric data were used to diagnose patients with definite or probable MD using criteria set by the American Academy of Otolaryngology-Head and Neck Surgery. RESULTS: In total, 113 patients with definite or probable MD were included in the study. The mean age of the patients was 60 ± 15 years with no gender predominance (49.6% male and 50.4% female). A total of 57 (50%) patients were presented with headaches. Among the migraine headache cohort, headache and otalgia were on the same side as the MD ear affected by hearing loss. In addition, in patients who present with otalgia as the primary feature of headache, otalgia was more likely to be on the same side as the ear affected by the hearing loss. CONCLUSIONS: The high prevalence of migraine symptoms on the same side of the ear affected by MD among this cohort could suggest a shared pathophysiology in both MD and migraine, possibly involving migraine-related changes in both the cochlea and vestibule.

Percepção de familiares e autopercepção de idosos usuários de dispositivos de amplificação quanto à restrição de participação causada pela deficiência auditiva / Perception of family members and self -perception of the elderly users of amplification devices regarding the restriction of participation caused by hearing impairment / Percepción de los miembros de la familia y la autopercepción de los ancianos usuarios de dispositivos de amplificación sobre la restricción de la participación causada por la discapacidad auditiva

Introdução: A deficiência auditiva tem um efeito profundo na vida dos idosos. O apoio dos familiares no processo de reabilitação cria meios para facilitar a aceitação da deficiência e o uso dos dispositivos auditivos. Objetivo: Analisar a percepção dos familiares quanto à restrição da participação causada pela deficiência auditiva em indivíduos idosos usuários de aparelho de amplificação sonora individual (AASI) e compará-la com a autopercepção do próprio idoso quando a este aspecto. Métodos: A amostra foi composta por 48 indivíduos, que foram divididos em dois grupos, sendo GI o grupo de idosos, composto por 24 idosos com perda auditiva sensorioneural bilateral usuários de AASI; e GF o grupo de familiares, composto por 24 familiares, que acompanhavam esses idosos. Os participantes do GI responderam ao questionário de autoavaliação Hearing Handicap Inventory for the Elderly (HHIE) e os participantes do GF responderam ao questionário Hearing Handicap Inventory for the Elderly for Spouses (HHIE-SP). Resultados: Não houve correlação entre o tempo de uso do AASI e o escore obtido no questionário. Observou-se que, quanto maior a idade do idoso, piores foram os resultados encontrados no domínio "emocional" do HHIE para o grupo GI e para os domínios "social" e "emocional" para o grupo GF. Além disso, houve correlação entre os dois grupos, indicando que, quanto piores os resultados no HHIE para o GI, também foram piores os resultados no HHIE-SP respondido pelo GF. Conclusão: Arestrição de participação social e os aspectos emocionais influenciados pela perda auditiva em indivíduos idosos usuários de AASI são fatores percebidos pelos familiares que os acompanham nas consultas fonoaudiológicas.

Introduction: Hearing loss has a profound effect on the lives of the elderly. The support of family members in the rehabilitation process creates ways to facilitate the acceptance of the disability and the use of hearing devices. Objective: To analyze the perception of family members regarding the restriction of participation caused by hearing impairment in elderly individuals users of hearing aids and compare it with the self-perception of the elderly in this regard. Methods: The sample consisted of 48 individuals, who were divided into two groups, EG being the elderly group, composed of 24 elderly people with bilateral sensorineural hearing loss, who use HA; and FG the group of family members, composed of 24 family members, who accompanied these elderly people. EG participants answered the Hearing Handicap Inventory for the Elderly (HHIE) self-assessment questionnaire and FG participants answered the Hearing Handicap Inventory for the Elderly for Spouses (HHIE-SP). Results: There was no correlation between the time of HA use and the score obtained in the questionnaire. It was observed that the older the person, the worse the results found in the "emotional" domain of the HHIE for the EG group, and the "social" and "emotional" domains for the FG group. In addition, there was a correlation between the two groups, indicating that the worse the results in the HHIE for the EG, the worse the results in the HHIE-SP answered by the GF. Conclusion: The restriction of social participation and the emotional aspects influenced by hearing loss in the elderly who use HA are factors perceived by family members who accompany them in audiology appointments.

Introducción: La discapacidad auditiva tiene un profundo efecto en la vida de los adultos mayores. El apoyo de los familiares en el proceso de rehabilitación crea vías para facilitar la aceptación de la discapacidad y el uso de audífonos. Objetivo: Analizar la percepción de los familiares sobre la restricción de la participación causada por la deficiencia auditiva en ancianos usuarios de audífonos y compararla con la autopercepción de los ancianos al respecto. Métodos: La muestra estuvo conformada por 48 individuos, quienes fueron divididos en dos grupos, siendo GI el grupo de adultos mayores, compuesto por 24 adultos mayores con hipoacusia neurosensorial bilateral, que utilizan audífonos; y GF el grupo de familiares, compuesto por 24 familiares, que acompañaban a estos individuos. Los participantes del GI respondieron el cuestionario Hearing Handicap Inventory for the Elderly (HHIE) y los participantes del GF respondieron el cuestionario Hearing Handicap Inventory for the Elderly for Spouses (HHIE-SP). Resultados: No hubo correlación entre el tiempo de uso del audífono y la puntuación obtenida en el cuestionario. Se observó que a mayor edad del adulto mayor, peores resultados encontrados en el dominio "emocional" del HHIE para el grupo GI y para los dominios "social" y "emocional" para el grupo GF. Además, hubo correlación entre los dos grupos, indicando que a peores resultados en el HHIE para el GI, peores resultados en el HHIE-SP contestado por el GF. Conclusión: La restricción de la participación social y los aspectos emocionales influenciados por la hipoacusia en adultos mayores usuarios de audífonos son factores percibidos por los familiares que los acompañan en las consultas de audiología.(AU)
