Bae SH, Lee Y, Jung J. Increased incidence of unilateral sudden sensorineural hearing loss in patients with hematological malignancies requiring hematopoietic stem cell transplantation. Clin Otolaryngol 2021; 46:1278-1281. [PMID: 34174171 DOI: 10.1111/coa.13829] [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: 04/19/2021] [Revised: 06/03/2021] [Accepted: 06/13/2021] [Indexed: 12/01/2022]
Abstract
Haematopoietic stem cell transplantation (HSCT) may dramatically alter the immunity of a recipient. Transient immunodeficiency that occurs before and after HSCT could be associated with the development of sudden sensorineural hearing loss (SSNHL), which is presumed to be often due to viral aetiology. We found an incidence of SSNHL of 29.4 per 10,000 person-years in patients receiving HSCT, 12-fold higher than reported for background population incidence. Development of SSNHL tended to cluster early after diagnosis of haematological malignancies, rather than around date of treatment with HSCT. Increased risk of unilateral SSNHL in patients with haematological malignancy may relate to underlying disease rather than treatment.

Abstract
OBJECTIVE To analyze the factors affecting the long-term prognosis of tinnitus accompanied by unilateral idiopathic sudden sensorineural hearing loss (SSNHL). METHODS A total of 161 patients with sudden hearing loss (HL) accompanied by tinnitus were enrolled. All patients had two separate telephone follow-ups and were asked about changes in tinnitus. The severity of tinnitus at admission and the outcome at discharge were assessed in terms of the patients' sex, age, level of HL, type of audiogram, etc. Results: The prognosis of tinnitus after SSNHL had no relationship with grades of HL or hearing recovery. Initial tinnitus level was remarkably associated with tinnitus improvement at discharge and was an independent risk factor for the long-term prognosis of residual tinnitus after SSNHL (odds ratio 0.722, 95% confidence interval 0.550-0.949, p = 0.019), and the median recovery time was 23.00 ± 3.80 months. CONCLUSIONS Residual tinnitus after SSNHL has a tendency of self-recovery. The short-term prognosis of tinnitus may be related to psychological changes caused by hearing recovery, while the long-term prognosis of residual tinnitus after SSNHL is related only to the initial tinnitus level, with a median recovery time of approximately 2 years.

Abstract
Tinnitus can be a burdensome condition on both individual and societal levels. Many aspects of this condition remain elusive, including its underlying mechanisms, ultimately hindering the development of a cure. Interdisciplinary approaches are required to overcome long-established research challenges. This review summarizes current knowledge in various tinnitus-relevant research fields including tinnitus generating mechanisms, heterogeneity, epidemiology, assessment, and treatment development, in an effort to highlight the main challenges and provide suggestions for future research to overcome them. Four common themes across different areas were identified as future research direction: (1) Further establishment of multicenter and multidisciplinary collaborations; (2) Systematic reviews and syntheses of existing knowledge; (3) Standardization of research methods including tinnitus assessment, data acquisition, and data analysis protocols; (4) The design of studies with large sample sizes and the creation of large tinnitus-specific databases that would allow in-depth exploration of tinnitus heterogeneity.

Abstract
INTRODUCTION A significant number of sensorineural hearing loss (SSNHL) patients had no noticeable hearing improvement after glucocorticoid (GC) treatment. In the present study, we examined expression of the nuclear factor erythroid 2-related factor 2 (NRF2) and histone deacetylase 2 (HDAC2) in peripheral blood mononuclear cells (PBMCs) of refractory SSNHL patients to study the role of NRF2-HDAC2 pathway in GC insensitivity hearing improvement after GC treatment, which is usually referred to as refractory SSNHL or GC insensitivity. MATERIALS AND METHODS Forty-four refractory SSNHL patients were treated by intratympanic GC infusion. Hearing was tested in all patients before and after treatment by pure tone hearing test. NRF2/HDAC2 mRNA and protein levels were examined in PBMCs of refractory SSNHL patients before and after treatment. PBMCs from healthy volunteers were used as normal controls. RESULTS According to the hearing improvement after treatment, patients were assigned into 2 groups: the intratympanic GC sensitive (IGCS) group (hearing recovery ≥15 dB HL) and the intratympanic GC insensitive (IGCI) group (hearing recovery <15 dB HL). Before treatment, the NRF2 mRNA level was lower in all patients than the normal control group. After treatment, NRF2 and HDAC2 mRNA and protein levels were increased in the IGCS group, while no significant change was observed in the IGCI group. CONCLUSION Low response of NRF2/HDAC2 proteins is associated with GC insensitivity in SSNHL. We speculate that the NRF2-HDAC2 pathway affects GC sensitivity in SSNHL patients.

Abstract
OBJECTIVE Sudden sensorineural hearing loss (SSNHL) is an ideal entity for quality indicator (QI) development, providing treatment challenges resulting in variable or substandard care. The American Academy of Otolaryngology-Head and Neck Surgery recently updated their SSNHL guidelines. With SSNHL demonstrating a large burden of illness, this study sought to leverage the updated guidelines and develop QIs that support quality improvement initiatives at an individual, institutional, and systems level. METHODS Candidate indicators (CIs) were extracted from high-quality SSNHL guidelines that were evaluated using the Appraisal of Guidelines for Research and Evaluation II tool. Each CI and its supporting evidence were summarized and reviewed by a nine-member expert panel based on validity, reliability, and feasibility of measurement. Final QIs were selected from CIs using the modified RAND Corporation-University of California, Los Angeles appropriateness methodology. RESULTS Fifteen CIs were identified after literature review. After the first round of evaluations, the panel agreed on 11 candidate indicators as appropriate QIs with 2 additional CIs suggested for consideration. An expert panel meeting provided a platform to discuss areas of disagreement before final evaluations. The expert panel subsequently agreed upon 11 final QIs as appropriate measures of high-quality care for SSNHL. CONCLUSION The 11 proposed QIs from this study are supported by evidence and expert consensus, facilitating measurement across a wide breadth of quality domains. With the recently updated SSNHL guidelines, and a greater focus on quality improvement opportunities, these QIs may be used by healthcare providers for targeted quality improvement initiatives.

Abstract
OBJECTIVE To analyze the etiologies, treatments, and outcomes of sensorineural hearing loss (SSNHL) during pregnancy. STUDY DESIGN Retrospective chart review of 25 pregnant patients treated for SSNHL between January 2012 and September 2019. Forty-nine age matched non-pregnant women with severe and profound hearing loss diagnosed with SSNHL during the same period served as controls. Data were recorded on age, symptoms, onset of hearing loss, audiometric results, treatments, and outcomes. RESULTS The mean age was 29.6 years (range 23-38 years). Intratympanic steroids (ITS) were administered in 15 (60.0%) pregnant women with SSNHL. Three women were treated with postauricular steroids only, while another woman was treated with intravenous ginkgo leaf extract and dipyridamole. The remaining six women received no medications. More than half (8/15, 53.3%) of pregnant women with SSNHL receiving ITS experienced hearing improvement. Pregnant women with profound hearing loss who received no medication had no hearing improvement. Most pregnant women with SSNHL (12/15, 80.0%) had higher fibrinogen levels than controls (mean values 3.77±0.71 g/L and 2.54±0.48 g/L, respectively). CONCLUSION Fibrinogen could be a risk factor for SSNHL during pregnancy. ITS may benefit pregnant women with severe and profound SSNHL.

Abstract
This retrospective study investigated the use of electroacupuncture (EA) for the treatment of patients with sudden sensorineural hearing loss (SSNHL).Between May 2016 and April 2020, 140 patients with SSNHL were retrospectively analyzed. They were allocated to a treatment group (n = 70, received EA) and a control group (n = 70, received acupuncture). They received EA or acupuncture for a total of 3 months. The outcomes included average hearing threshold (AHT), tinnitus (as assessed by tinnitus handicap inventory [THI]), dizziness (as measured by dizziness handicap inventory [DHI]), and adverse events (AEs).After treatment, patients in both groups exerted more reduction in HT (P < .01), THI (P < .01), and DHI (P < .01), than those before the treatment. Furthermore, patients in the treatment group showed more relief in HT (P < .01), THI (P < .01), and DHI (P < .01), than those of patients in the control group. When it comes to AEs, both modalities had similar safety profile.The findings of this retrospective study indicated that the effectiveness of EA is superior to acupuncture in treating SSNHL. Future high quality studies are needed to warrant the present findings.

Abstract
Hearing loss affects >5% of the global population and therefore, has a great social and clinical impact. Sensorineural hearing loss, which can be caused by different factors, such as acoustic trauma, aging, and administration of certain classes of drugs, stems primarily from a dysfunction of the cochlea in the inner ear. Few therapeutic strategies against sensorineural hearing loss are available. To develop effective treatments for this disease, it is crucial to precisely determine the behavior of ototoxic and therapeutic agents in the microenvironment of the cochlea in live animals. Since the 1980s, a number of studies have addressed this issue by different methodologies. However, there is much less information on pharmacokinetics in the cochlea than that in other organs; the delay in ontological pharmacology is likely due to technical difficulties with accessing the cochlea, a tiny organ that is encased with a bony wall and has a fine and complicated internal structure. In this review, we not only summarize the observations and insights obtained in classic and recent studies on pharmacokinetics in the cochlea but also describe relevant analytical techniques, with their strengths, limitations, and prospects.

Abstract
Objective: This study aims to investigate the impact of the coronavirus disease 2019 (COVID-19) epidemic on dizziness/vertigo outpatients in a neurological clinic in China. Methods: Against the background of the COVID-19 epidemic, the data of patients who visited the neurological clinic of Beijing Chaoyang Hospital West Branch during the pandemic (February 1-May 30, 2020) and the corresponding period in 2019 (February 1-May 30, 2019) were analyzed, and patients with dizziness/vertigo from these two periods were compared to discover their demographic features and etiologic distribution according to their age and sex. Result: The absolute number of neurological outpatients decreased from 14,670 in 2019 to 8,763 in 2020 (-40.3%), with a corresponding decline in dizziness/vertigo patients (2019: n = 856; 2020: n = 1,436, -40.4%). Dizziness/vertigo was more common in women than men in these two periods (2019: women = 63.6%; 2020: women = 63.1%, p = 0.82). The overall etiology distribution was different among all disorders between the two periods (p < 0.001). There was an increase in benign paroxysmal positional vertigo (BPPV) (2019 vs. 2020: 30.7 vs. 35%, p < 0.05) and psychogenic/persistent postural perceptual dizziness (PPPD) (2019 vs. 2020: 28.5 vs. 34.6%, p < 0.05) while a decrease in vascular vertigo during the epidemic (2019 vs. 2020: 13 vs. 9.6%, p < 0.05). During the epidemic, the top three causes of dizziness/vertigo were BPPV (35%), psychogenic/PPPD (34.6%), and vascular vertigo (9.6%). A female predominance was observed in BPPV (women = 67.7%, p < 0.05) and psychogenic/PPPD (women = 67.6%, p < 0.05). In addition, the etiology ratio of different age groups was significantly different (p < 0.001). The most common cause for young and young-old patients was BPPV, and the most common cause for middle-aged and old-old patients was psychogenic/PPPD. Conclusion: The absolute number of outpatients with dizziness/vertigo during the COVID-19 pandemic was reduced during the early period of the COVID-19 outbreak. BPPV and psychogenic/PPPD were more abundant, and vascular vertigo was less frequent. Based on those data, health-care management policy for dizziness/vertigo and mental disorder should be developed during the outbreak of COVID-19 and other infective diseases.

[PMID: 33968458 PMCID: PMC8081636 DOI: 10.1155/2021/6632344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 03/04/2021] [Accepted: 04/08/2021] [Indexed: 11/18/2022] Open
Abstract
Granulomatosis with polyangiitis (GPA) is a severe systemic vasculitis that commonly affects the paranasal sinuses, upper and lower respiratory tracts, and kidneys. GPA has also been associated with sensorineural hearing loss (SNHL), through inflammation of the cochlear apparatus. Early recognition, diagnostic laboratory evaluation, and appropriate treatment are essential to improve outcomes and achieve remission for patients with GPA. Here, we present a case of bilateral sudden sensorineural hearing loss (SSNHL) and distal symmetric polyneuropathy as the first presenting signs of GPA. A specific diagnostic work-up to rule out autoimmune inner-ear disease in patients with bilateral SSNHL is not clearly stated in the clinical practice guidelines from the American Academy of Otolaryngology-Head and Neck Surgery. The aim of this paper is to delineate an appropriate diagnostic work-up for patients with bilateral SSNHL when there is concern for autoimmune disease.

Abstract
BACKGROUND Sudden hearing loss (SHL) is associated with serious systematic conditions such as neoplasms, vascular events, autoimmune diseases, infections, and iatrogenic injury. Some authors report that SHL can be an early warning sign of impending vertebrobasilar ischemic stroke. It is important to distinguish stroke from benign disease.
CASE SUMMARY A 48-year-old male patient presented with SHL and vertigo as first symptoms. Diffusion-weighted imaging revealed high signal intensity in the left posterior inferior cerebellar artery territory of the cerebellar hemisphere and high signal intensity in the right pons and bridge cerebellar arm, confirming that the patient had cerebral infarction. Treatment with antiplatelet drugs, steroid anti-inflammatory drugs, and neurotrophic nerve therapy promoted blood circulation and removed blood stasis, and the symptoms of the patient were significantly improved.
CONCLUSION SHL and vertigo could be the initial symptoms of vertebrobasilar ischemic stroke.

Abstract
OBJECTIVES This study compared sudden deafness (SD) cases in 20-year age bands to investigate their causes and treatment outcome. DESIGN Retrospective study. STUDY SAMPLES 178 unilateral SD patients were divided into four 20-year age-groups, namely Groups I (aged 0-19 years, n = 6), II (aged 20-39 years, n = 33), III (aged 40-59 years, n = 63), and IV (aged 60-79 years, n = 76). METHODS An inner ear test battery and/or serology assay were performed. RESULTS Incidence of SD in relation to overall neurotological cases did not significantly differ among the four groups. Groups I and II showed two or three audiographic patterns, while Groups III and IV had six audiographic patterns indicating that the aetiology of Groups I and II may be of the same origin, while Groups III and IV had multiple aetiologies. The hearing improvement rate was significantly higher in Groups III (62%) and IV (62%) than in Groups I (16%) and II (33%). CONCLUSION SD inevitably affects individuals of all ages. Significant differences in the audiographic patterns and speculative causes may account for various outcomes of treatment in each 20-year age band. Those SD patients aged 40-59 and 60-79 years showed significantly better treatment outcomes than those aged 0-19 and 20-39 years.

Abstract
This study investigated the etiology and treatment outcome in sudden sensorineural hearing loss (SSHL) patients following dental procedure. During the past 2 decades, only 6 patients with SSHL following dental procedure were experienced including tooth extraction in 5 and endodontic treatment in 1. Three were males and 3 were females, with ages ranging from 10 to 75 years (median, 47 years). All patients underwent an inner ear test battery. Types of audiogram consisted of total deafness in 3 ears, flat-type loss in 2 ears, and high-tone loss in 1 ear. The pretreatment mean hearing level from 4 frequencies was 76 ± 37 dB for the lesion ears, significantly higher than 23 ± 15 dB for the opposite healthy ears. The treatment outcome is unsatisfactory. Five patients remained hearing unchanged 3 months after treatment. Only 1 (17%) patient had hearing improvement who was proved as having reactivation of the varicella-zoster virus. In conclusion, reactivation of the varicella-zoster virus may be one of the etiologies for SSHL patients following dental procedure. Serological assay coupled with MR imaging may help identify the etiology, determine the medication, and predict the outcome.

Abstract
OBJECTIVES Recent publications reported that patients with rheumatoid arthritis (RA) experience an increased risk of suffering sudden sensorineural hearing loss (SSNHL), however, these cases are poorly understood. This study aims to explore the clinical presentations and hearing recovery of SSNHL patients with RA. STUDY DESIGN Retrospective study. SETTING Tertiary medical center. PATIENTS Forty-seven SSNHL patients with RA (RA group) and 431 SSNHL patients without RA (non-RA group) were recruited between April 2015 and June 2019. INTERVENTIONS In the non-RA group, all patients were administrated with oral steroids. In the RA group, 21 patients were treated with oral steroid (OS group) and 26 patients were administrated with intratympanic steroids plus oral steroids (IS+OS group). MAIN OUTCOME MEASURES We explored the clinical features and hearing recovery of SSNHL patients with RA in comparison with patients without RA, we also evaluated the therapeutic effect of combined steroids in SSNHL patients with RA. RESULTS RA group had higher initial hearing loss level (mean 68.5 dB), final hearing threshold (mean 52.3 dB), the rates of profound hearing loss (48.9%), and no recovery (48.9%) than non-RA group (mean 55.1 dB, mean 34.8 dB, 32.9 and 27.6%, all p < 0.05), however, had lower hearing gains (mean 16.1 dB) and the rate of partial recovery (12.8%) than non-RA group (mean 20.3 dB and 28.8%, all p < 0.05). Furthermore, IS+OS group had higher hearing gains (mean 21.1 dB) and lower rate of no recovery (30.8%) than in the OS group (mean 10.0 dB and 71.4%, all p < 0.05). CONCLUSIONS SSNHL patients with RA experienced severe hearing loss and had poor hearing prognosis. IS+OS provide better hearing recovery than OS for this population.

Abstract
BACKGROUND Autoimmunity may play an important role in sudden onset sensorineural hearing loss. However, little is known about the relationship between immunoglobulin E (IgE) and acute low-tone sensorinerual hearing loss (ALHL). OBJECTIVES To investigate the relationship between IgE level and endolymphatic hydrops and outcomes of ALHL. METHODS A total of 242 subjects with sudden onset hearing loss, including 115 with ALHL and 127 with idiopathic sudden sensorineural hearing loss (ISSHL), were included in this study. Peripheral venous blood samples of 242 subjects were collected for detection. Clinical data, IgE level, and distribution of allergens were compared between the ALHL and ISSHL groups. The ALHL group received an electrocochleogram (ECochG) test and a follow-up in the outpatient unit or by telephone to evaluate outcomes. RESULTS Compared to the values in the ISSHL group, a significantly younger onset age (42.30±14.33 years old), higher female onset proportion (72/115, 62.61%), increased total IgE level (median: 66.47, interquartile range: 24.56, 180.96, IU/mL) and specific IgE level (median: 9.42, interquartile range: 1.42, 22.23 IU/mL) were noted in the ALHL group. A clear difference in allergen distribution was noted between the ALHL and ISSHL groups (p=.001). Total IgE and specific IgE levels were factors that contributed to the SP/AP ratio in the electrocochleogram (ECochG) (R2=0.413) in ALHL group. Finally, during the follow-up (17.61±3.46 months) for the ALHL group, 37 subjects recurred, and 17 subjects developed Meniere Disease. In the ROC curve for ALHL recurrence, the area under the curve (AUC) of total IgE was 0.709 and that of specific IgE was 0.679. For MD transformation, the AUC of total IgE was 0.736 and that of specific IgE was 0.716. CONCLUSIONS High IgE levels correlated with an enhanced SP/AP ratio in ALHL. High IgE levels could be used as a predictor of ALHL recurrence and MD transformation.

T2 relaxation time shortening in the cochlea of patients with sudden sensory neuronal hearing loss: a retrospective study using quantitative synthetic magnetic resonance imaging. Eur Radiol 2021; 31:6438-6445.

Abstract
OBJECTIVES High cochlear signal intensity on three-dimensional (3D) T2 fluid-attenuated inversion recovery (FLAIR) sequences in patients with sudden sensorineural hearing loss (SSNHL) has been reported. Here, we evaluated the cochlear T2 relaxation time differences in patients with idiopathic SSNHL using quantitative synthetic MRI (SyMRI). METHODS Twenty-four patients with unilateral SSNHL who underwent precontrast conventional 3D FLAIR and SyMRI were retrospectively included. T1 and T2 relaxation times and the proton density (PD) of the bilateral ears were measured by manually drawn regions of interest. Wilcoxon signed-rank tests and intra- and interobserver correlation analyses were performed. Qualitative analysis was also performed to determine the presence and laterality of the asymmetric high signal intensity on synthetic FLAIR (SyFLAIR) images. RESULTS The T2 relaxation time was significantly lower in the affected (basal and apico-middle turns) than in the unaffected cochlea (basal turn: 519 ± 181.3 vs. 608.8 ± 203.6, p = 0.042; apico-middle turn: 410.8 ± 163.8 vs. 514.5 ± 186.3, p = 0.037). There were no significant differences in the T1 relaxation time and PD between the affected and unaffected ears (p > 0.05). Additionally, three patients without asymmetric signal intensity on conventional MRI showed asymmetric increased signal intensity in the affected ear on SyFLAIR. CONCLUSIONS The T2 relaxation time was significantly shorter in the affected than in the unaffected cochlea of patients with idiopathic SSNHL. The SyMRI-derived T2 relaxation time may be a promising imaging marker, suggesting that the changes in inner ear fluid composition are implicated in the idiopathic SSNHL development. KEY POINTS • T2 relaxation time was significantly lower in the affected than in the unaffected cochlea. • SyFLAIR showed increased lesion conspicuity compared to conventional 3D-FLAIR in detecting asymmetric high signal intensity of the affected side. • SyMRI-derived T2 relaxation time may be a promising imaging marker of the affected ear in patients with idiopathic SSNHL.

Abstract
Tinnitus, acute or chronic, is one of the most common and refractory disorders. Acute tinnitus is a symptom that is a warning sign when compared with chronic tinnitus. Although hearing loss initiates acute tinnitus, the relationship between hearing loss and tinnitus is far from straightforward. Other factors beyond the auditory system may play important roles in the occurrence of acute tinnitus. To address this issue, we propose an integrated regulation theory of the possible physical causes of acute tinnitus, and summarize a classification system for acute tinnitus based on this regulation theory to help guide clinical treatment.

Abstract
OBJECTIVES Recurrent idiopathic sudden sensorineural hearing loss (ISSNHL) is a rare disease. In this study, we evaluated the correlations between hearing recovery after the first and recurrent episodes of ISSNHL and characterized the clinical features of different episodes of ISSNHL. METHODS This retrospective study was conducted by reviewing medical records pertaining to the period 2008-2018. A total of 30 patients (16 male, 14 female) who had experienced at least two episodes of ISSNHL were included. All patients were had received steroid therapy (including systemic and IT) and/or hyperbaric oxygen therapy within 2 weeks after the onset of disease. The SDRG's criteria was used for the grading of hearing recovery. RESULTS The median age at the first and second episode of ISSNHL was 48 and 53.5 years, respectively; a total of 30% of patients presented with vertigo in the first episode and 40% presented with vertigo in the second episode. The hearing outcomes of both episodes showed significant improvement after treatment. The rate of complete recovery after the first and second episodes was 46.67% and 33.33%, respectively. A significant positive correlation was observed between the treatment outcomes of the first and second episodes (r = 0.721, p < 0.001). CONCLUSION In ISSNHL, hearing recovery after a recurrent episode is significantly correlated with the hearing outcome after the initial episode (p = 0.042). The treatment outcome of the first episode is a prognostic factor for the outcomes of recurrent episodes.

Abstract
Objectives To evaluate hearing outcome of salvage treatment with intratympanic steroids (ITS) in idiopathic sudden sensorineural hearing loss (ISSNHL) refractory to initial systemic steroid (SS) therapy. Material and methods A retrospective medical chart review was conducted on 54 consecutive patients with ISSNHL refractory to SS. Salvage treatment with a low dose intratympanic dexamethasone (4 mg/ml) was offered after one week of primary treatment. Patients were divided into two groups: 25 patients accepted ITS (treatment group) and 29 patients did not undergo additional treatment (control group). A pure tone average (PTA) gain of at least 10 dB was considered hearing improvement. Results Hearing improvement rate was higher in ITS group compared to control group (40% vs. 13.8%, p = 0.035). A mean PTA improvement of 8.6 ± 9.8 dB was observed in the ITS group and, whereas the control group had an average hearing gain of 0.7 ± 2 dB (p < 0.001). Audiometric analysis revealed a significant hearing gain in ITS group at all tested frequencies compared to control group (p < 0.05). Analysis of the selected variables, identified intratympanic steroid treatment as the only independent prognostic factor for hearing improvement (OR = 4.2, 95% CI: 1.1-15.7; p = 0.04). Conclusion Intratympanic low dose dexamethasone is effective in patients with incomplete hearing recovery after primary systemic steroid treatment.

Abstract
BACKGROUND Idiopathic sudden sensorineural hearing loss (ISSNHL) is an emergency disease, and its pathogenesis is still largely unknown, making it difficult to diagnose and develop a therapeutic strategy. To predict the treatment outcomes and further customize the treatment strategy, we used a physician decision support system that incorporates complex information from electronic health records. We first developed the infrastructure of the physician decision support system, including an integrated data warehouse and an automatic data de-identification workflow. METHODS We next conducted a cohort study to evaluate the treatment outcomes of 757 ISSNHL patients using the modified Siegel's criteria. The complete recovery (<25 dB) as a hearing outcome for ISSNHL patients was compared based on pretreatment hearing grades and disease onset with adjusted for age and sex after treatment initiation. RESULTS The results showed that a complete recovery hearing outcome based on pretreatment hearing grades and disease onset in consideration of age and sex was associated with a low risk of pretreatment hearing Grade 2 (26-45 dB) (adjusted odds ratio 12.3, 95% confidence interval [CI]: 4.8-31.3) and disease onset ≤7 days (adjusted odds ratio 13.9, 95% CI: 4.2-45.8), respectively. Hearing recovery outcomes among complete recovery and noncomplete recovery (>25 dB) subjects according to pretreatment hearing grades were 32.9% (Grade 2 or 26-45 dB HL), 25.4% (Grade 3 or 46-75 dB HL), 31.1% (Grade 4 or 76-90 dB), and 4.5% (Grade 5, or >90 dB HL) (p < 0.0001). Patients with pretreatment hearing Grade 2 who received treatment within ≤7 days of disease onset had the highest rate of complete recovery (32.9%, 23/70). CONCLUSION In summary, using the physician decision support system, we successfully identified two predictors, the pretreatment hearing Grade 2 (26-45 dB) and treatment within ≤7 days of disease onset, associated with the highest odds of achieving complete recovery (<25 dB) of hearing in patients with ISSNHL.

Abstract
Sudden sensorineural hearing loss (SSNHL) patients with vertigo have a poorer prognosis. However, the factors associated with hearing recovery remain uncertain. This retrospective study was to evaluate the association between hearing characteristics/hearing recovery and the patterns of vestibulocochlear lesions in SSNHL patients with vertigo. Patients were classified into groups according to the patterns of vestibular dysfunction. We not only compared hearing characteristics and prognosis among subgroups but also determined the potential association between vestibular lesion location and hearing recovery. The shapes of the audiogram differed significantly between patients with normal vestibular function and patients with vestibular dysfunction (p = 0.022). Patients whose audiogram indicated profound hearing loss were 3.89 times more likely to have vestibular dysfunction than those whose audiogram shape indicated low-frequency hearing loss (95% CI, 1.02–14.86, p = 0.047). Patients who had saccule dysfunction were 0.11 times as likely to have hearing recovery than those who had normal saccule function (95% CI, 0.11–0.31, p = 0.001). When adjusted for sex and age, patients who had saccule dysfunction were 0.07 times as likely to have hearing recovery than those who had normal saccule function (95% CI, 0.02–0.22, p = 0.001). Abnormal results following cVEMP testing may be a potential predictive factor for poor hearing recovery.

Abstract
BACKGROUND We aimed to evaluate the association between mean platelet volume, platelet distribution width (PDW), platelet count (PC) and plateletcrit (PCT), and the presence of sudden sensorineural hearing loss (SSNHL) and treatment response. In the literature, there is no study that investigates the platelet functions in diabetic patients with SSNHL. METHODS The patients were retrospectively assigned into Group 1 (68 diabetic patients with SSNHL), Group 2 (63 nondiabetic patients with SSNHL) and Group 3 (64 healthy controls). RESULTS PC was not significantly different between the groups (p > 0.05). MPV, PDW and PCT values were significantly higher in Group 1 as compared to Groups 2 and 3 (p < 0.05). Platelet parameters were not significantly different between the patients who were responsive and nonresponsive to the treatment. Therefore, the platelet parameters did not affect prognosis significantly in this study samples (p > 0.05). CONCLUSIONS This study showed that platelet parameters did not have a significant effect as a prognostic and predictive value in diabetic and nondiabetic patients with SSNHL. Further studies with more homogenous and larger study groups investigating the platelet parameters are needed to demonstrate microvascular damage and vascular alterations induced by diabetes mellitus.

Abstract
BACKGROUND Evidence suggests that glucocorticoids are important in the treatment of sudden hearing loss (SHL) and Meniere's disease (MD). However, different glucocorticoid administration methods may have a significant impact on treatment outcomes. OBJECTIVE This study aimed to investigate effects of different glucocorticoid administration methods on sudden hearing loss and Meniere's disease. METHODS In this study, glucocorticoids were administered orally in 18 patients, by retroauricular injection in 15 patients and by intratympanic injection in 15 patients. White blood cell (WBC) count, serum K+, fasting plasma glucose (FPG), body temperature, heart rate and blood pressure were used to evaluate effects of glucocorticoids on patients with hearing loss. Visual analog scale (VAS) of pain and sleep disorders were also surveyed, and pure tone audiometry (PTA) results were compared among groups to evaluate efficacy of different glucocorticoids administration methods. RESULT WBC count, heart rate and blood pressure were higher in patients taking oral glucocorticoids, while body temperature, serum K+ and FPG levels did not change in all three groups. However, patients who received intratympanic injection of glucocorticoids experienced more pain, while those taking oral glucocorticoids reported more sleep impairment. Treatment efficacy on hearing loss was not significantly different among the three groups. CONCLUSION These findings suggest that systemic glucocorticoid administration can result in greater whole body responses than local administration, but with similar hearing treatment efficacy.

Abstract
Sudden sensorineural hearing loss seems to become a serious social health problem in modern societies. According to the World Health Organization (WHO) reports, adult-onset sensorineural hearing loss is found to be one of the leading diseases at the global level, especially in high-income countries, and is foreseen to move up from the 14th to 7th leading cause of the global burden of diseases by the year 2030. Although the direct mortality rate of this disease is very low, its influence on quality of life is huge; that is the reason why the implementation of the most effective and the safest therapies for the patient is crucial for minimizing the risk of complications and adverse reactions to treatment. The aim of this paper is to present hyperbaric oxygen therapy (HBOT) as a medical procedure useful in the treatment of sudden sensorineural hearing loss as adjunctive therapy of high efficacy. This paper focuses on the molecular mechanisms of action and clinical effectiveness of HBOT in the treatment of idiopathic sudden deafness, taking into consideration both the benefits and potential risks of its implementation.

Abstract
Background Sudden sensorineural hearing loss (SSNHL) is currently treated with a combination of drugs, predominantly with glucocorticoids (GCs). However, the mechanisms of action of GCs in SSNHL are unknown. This study aimed to analyze the role of endoplasmic reticulum stress (ERS) in SSNHL pathogenesis and prognosis. Material/Methods In this study, we evaluated the expression and activation status of the protein kinase RNA-like endoplasmic reticulum kinase (PERK)-C/EBP homologous protein (CHOP) pathway in peripheral blood mononuclear cells (PBMCs) from patients with SSNHL and compared them with those in healthy controls. We also compared differences in expression of activating transcription factor 4 (ATF4) and CHOP before and after glucocorticoid treatment in patients with improved and unimproved SSNHL. Results Treatment with GCs significantly improved hearing in 55% of patients with SSNHL. Levels of phosphorylated PERK (p-PERK) and phosphorylated eukaryotic initiation factor 2α were increased in PBMCs from patients with SSNHL compared with healthy controls. ATF4 and CHOP expression were also significantly elevated. After treatment, the amount of ATF4 and CHOP proteins in PBMCs in the patients whose SSNHL improved was significantly reduced compared with the levels measured before treatment in all patients with SSNHL. The expression of the ATF4 and CHOP proteins in PBMCs in the unimproved group, however, was not significantly changed relative to pretreatment levels. Conclusions ERS may play a significant role in the pathogenesis of SSNHL, and the responsiveness of the condition to GC-mediated mitigation of ERS may be one of the key factors that affect patient prognosis.

Abstract
Background Sudden sensorineural hearing loss (SSNHL) is an otologic emergency and could lead to social difficulties and mental disorders in some patients. Although many studies have analyzed altered brain function in populations with hearing loss, little information is available about patients with idiopathic SSNHL. This study is aimed at investigating brain functional changes in SSNHL via functional magnetic resonance imaging (fMRI). Methods Thirty-six patients with SSNHL and thirty well-matched normal hearing individuals underwent resting-state fMRI. Amplitude of low-frequency fluctuation (ALFF), fractional ALFF (fALFF), and functional connectivity (FC) values were calculated. Results In the SSNHL patients, ALFF and fALFF were significantly increased in the bilateral putamen but decreased in the right calcarine cortex, right middle temporal gyrus (MTG), and right precentral gyrus. Widespread increases in FC were observed between brain regions, mainly including the bilateral auditory cortex, bilateral visual cortex, left striatum, left angular gyrus (AG), bilateral precuneus, and bilateral limbic lobes in patients with SSNHL. No decreased FC was observed. Conclusion SSNHL causes functional alterations in brain regions, mainly in the striatum, auditory cortex, visual cortex, MTG, AG, precuneus, and limbic lobes within the acute period of hearing loss.

Abstract
Introduction Prognosis of sudden sensorineural hearing loss may be predicted using several parameters of laboratory blood analysis. Objective To identify and investigate the most significant indicator parameters related to the poor prognosis of sudden sensorineural hearing loss. Methods Eighty-eight patients were included, and three groups were constituted: non-recovery group with14 patients, recovery group with 33 patients and control group with 41 individuals. We compared fibrinogen-to-albumin ratio, C-reactive protein-to-albumin ratio, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, white blood cell and hemoglobin of the groups. Then, we investigated the most significant indicator parameters related to the poor prognosis of sudden hearing loss. Results The mean hemoglobin, mean platelet-lymphocyte ratio and median white blood cell values did not significantly differ among three groups (p = 0.36, p = 0.86 and p = 0.79, respectively). A significant difference of median fibrinogen-albumin ratio, C-reactive protein-albumin ratio, neutrophil-to-lymphocyte ratio was evident among three groups (p < 0.001, p = 0.003 and p = 0.002, respectively). Median fibrinogen-albumin ratio, C-reactive protein-albumin ratio and neutrophil-to-lymphocyte ratio values were significantly greater in the non-recovery group, compared with the controls (p < 0.001, p = 0.003 and p = 0.005, respectively). Median fibrinogen-to-albumin ratio, C-reactive protein-to-albumin ratio and neutrophil-to-lymphocyte ratio were significantly greater in the recovery group, compared with the controls (p < 0.001, p = 0.013 and p = 0.005, respectively). Moreover, the median fibrinogen-albumin ratio was significantly greater in the non-recovery group compared with the recovery group (p = 0.017). However, no statistically significant difference of median C-reactive protein-albumin ratio, neutrophil-to-lymphocyte was evident between the non-recovery and recovery groups (p = 0.15). Conclusion Increased levels of fibrinogen-albumin ratio may be predictive for poor prognosis in patients with sudden sensorineural hearing loss.

Abstract
BACKGROUND Emerging evidence implicates excess weight as a potential risk factor for hearing loss. However, this association remained inconclusive. Therefore, we aimed to systematically and quantitatively review the published observational study on the association between body mass index (BMI) or waist circumference (WC) and hearing loss. METHODS The odds ratios (ORs) or relative risks (RRs) with their 95% confidence intervals (CIs) were pooled under a random-effects model. Fourteen observational studies were eligible for the inclusion in the final analysis. RESULTS In the meta-analysis of cross-sectional studies, the ORs for prevalent hearing loss were 1.10 (95% CI 0.88, 1.38) underweight, 1.14 (95% CI 0.99, 1.32) for overweight, OR 1.40 (95% CI 1.14, 1.72) for obesity, 1.14 (95% CI 1.04, 1.24) for each 5 kg/m2 increase in BMI, and 1.22 (95% CO 0.88. 1.68) for higher WC. In the meta-analysis of longitudinal studies, the RRs were 0.96 (95% CI 0.52, 1.79) for underweight, 1.15 (95% CI 1.04, 1.27) for overweight, 1.38 (95% CI 1.07, 1.79) for obesity, 1.15 (95% CI 1.01, 1.30) for each 5 kg/m2 increase in BMI, and 1.11 (95% CI 1.01, 1.22) for higher WC. CONCLUSIONS In summary, our findings add weight to the evidence that elevated BMI and higher WC may be positively associated with the risk of hearing loss.

Abstract
OBJECTIVES Sudden sensorineural hearing loss (SSNHL) may occur in post-irradiated nasopharyngeal carcinoma (NPC) survivors with a rare rate. This study was conducted to evaluate the clinical characteristics and prognosis of this population. STUDY DESIGN Retrospective cohort study. SETTING Tertiary otology referral center. PATIENTS Five hundred ninety nine SSNHL patients were recruited between January 2010 and January 2019. Patients were divided into two groups: NPC group (n = 24) and non-NPC group (n = 575). INTERVENTIONS All SSNHL patients were diagnosed by pure tone audiometry and treated with steroids, blood flow promoting agents, and hyperbaric oxygen therapy. MAIN OUTCOME MEASURES We evaluated the clinical characteristics and prognosis of post-irradiated SSNHL and identified prognostic factors by logistic regression analysis. RESULTS In the NPC group, the initial hearing threshold, contralateral hearing threshold, rate of vertigo, rate of profound hearing loss were all higher than in the non-NPC group (p < 0.05). Hearing gains and the rate of good recovery (both complete recovery and partial recovery) were lower in the NPC group than in the non-NPC group (p < 0.05). Logistic regression analysis revealed that NPC was significantly associated with poor hearing recovery (OR = 3.499, p = 0.040), and that a higher initial hearing threshold and longer treatment delay time were related to a poor prognosis (p < 0.05). CONCLUSIONS SSNHL occurred in post-irradiated NPC survivors often suffered a severe hearing loss with a high rate of accompanying vertigo. NPC may have an adverse impact on the prognosis of SSNHL, and higher initial hearing threshold and longer treatment delay time were indicators of poor hearing recovery.

Abstract
OBJECTIVES We aimed to verify the hypothesis that metabolic syndrome (MetS) and its components affect the prognosis of idiopathic sudden sensorineural hearing loss (ISNNHL). STUDY DESIGN A retrospective cohort study. SETTING Tertiary otology referral center. PATIENTS We divided patients who were diagnosed with ISSNHL between January 2015 and January 2018 into a MetS group and a Non-MetS group according to the diagnostic criteria of MetS. INTERVENTIONS We diagnosed ISSNHL patients by using pure-tone audiometry and treated them with oral steroids, blood flow promoting agents, and hyperbaric oxygen therapy. MAIN OUTCOME MEASURES We used multivariate logistic analysis to identify prognostic factors of ISSNHL. RESULTS The MetS group comprised 94 patients, and the Non-MetS group comprised 162 subjects. Despite the rate of hypertension, diabetes mellitus, hyperlipidemia, and BMI, no significant difference was observed between the two groups (p > 0.05). The rates of complete recovery and partial recovery of the MetS group were significantly lower than those of the Non-MetS group (p < 0.05). According to the multivariate analysis, MetS was significantly correlated with a poor prognosis (OR = 2.912, p = 0.008), and the OR increased with an increase in the number of MetS components. Late onset of treatment, high initial hearing threshold, and presence of diabetes mellitus and hyperlipidemia were associated with a poor prognosis (p < 0.05). CONCLUSIONS The presence of MetS may negatively affect the recovery of Chinese patients with ISSNHL, and the prognosis was poorer with an increase in the number of MetS components. Early onset of treatment, low initial hearing threshold and absence of diabetes mellitus, and hyperlipidemia are associated with favorable hearing recovery.

Abstract
This is a Brighton Collaboration case definition of the term "Sensorineural Hearing Loss" to be utilized in the evaluation of adverse events following immunization. The case definition was developed by a group of experts convened by the Coalition for Epidemic Preparedness Innovations (CEPI) in the context of active development of vaccines for Lassa Fever and other emerging pathogens. The case definition format of the Brighton Collaboration was followed to develop a consensus definition and define levels of diagnostic certainty, after an exhaustive review of the literature and expert consultation. The document underwent peer review by the Brighton Collaboration Network.

Abstract
Cochlear damage is often thought to result in hearing thresholds shift, whether permanent or temporary. The report of tinnitus in the absence of any clear deficit in cochlear function was believed to indicate that hearing loss and tinnitus, while comorbid, could arise independently from each other. In all likelihood, tinnitus that is not of central nervous system origin is associated with hearing loss. As a correlate, although a treatment of most forms of tinnitus will likely emerge in the years to come, curing tinnitus will first require curing hearing loss.

Abstract
OBJECTIVES Recent studies suggest that elevated neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are poor prognostic factors in sudden sensorineural hearing loss (SSNHL). We aimed to investigate the accuracy of this hypothesis by taking into account the effect of cardiovascular risk (CVR) factors. METHODS Medical records of 122 patients with SSNHL were reviewed retrospectively and grouped into 2 as; patients without CVR (group 1; n = 68) and patients having CVR (group 2; n = 54). Moreover, 60 control cases who did not have SSNHL were also included and grouped into 2 as; group 3 (n = 30) with CVR and group 4 (n = 30) healthy controls without having SSNHL or CVRs. Neutrophil (N), lymphocyte (L), platelet (Plt), NLR, and PLR between the groups and their relationship with the severity of hearing loss, recovery rates, and audiogram configurations were analyzed. RESULTS The highest N and NLR values were in group 1 and were significantly higher than the values of group 4 (P < .05, P < .01). There was no significant relationship between the groups in terms of L, Plt, or PLR values. The highest NLR and PLR values were determined in SSNHL patients with mild hearing loss, complete recovery, and up-sloping audiogram configuration (P > .05). CONCLUSIONS Elevated levels of N and NLR may be considered as strong laboratory findings showing an inflammatory response in the diagnosis of SSNHL, but the presence of CVR factors does not seem to increase the inflammatory response in SSNHL as expected. In patients with SSNHL, NLR and PLR elevation may indicate better prognosis.

Abstract
Idiopathic sudden sensorineural hearing loss (ISSNHL) is an emergency disease requiring immediate diagnosis and treatment. The incidence of ISSNHL in the Western countries’ population was estimated to 5–20 per 100,000 inhabitants. The etiology of ISSNHL remains unknown. Its pathogenesis is most often suggested to be due to a disturbed microcirculation and infection. Previous studies have reported that comorbidities, including hypertension, diabetes mellitus (DM), and hyperfibrinogenemia are risk factors of ISSNHL. This study aimed at investigating the clinical characteristics, laboratory parameters and comorbidities of patients with ISSNHL. Our study suggests that the annual incidence of ISSNHL in China mainland is 19 per 100 000. The clinical characteristics and prevalence of comorbidities of ISSNHL patients are different according to age distribution and hearing results. Moreover, the patients with vertigo, hypertension, DM and high TG suffered more often from severe hearing loss compared with the counterparts. This indicates that the cardiovascular and metabolic diseases (hypertension and hyperlipidemia) appeared to be closely associated with the occurrence and severity of ISSNHL.

Abstract
BACKGROUND Single-sided deafness (SSD) describes the presence of a unilateral severe to profound sensorineural hearing loss. SSD disrupts spatial hearing and understanding speech in background noise. It has functional, psychological and social consequences. Potential options for rehabilitation include hearing aids and auditory implants. Benefits and harms of these interventions are documented inconsistently in the literature, using a variety of outcomes ranging from tests of speech perception to quality of life questionnaires. It is therefore difficult to compare interventions when rehabilitating SSD. The Core Rehabilitation Outcome Set for Single Sided Deafness (CROSSSD) study is an international initiative that aims to develop a minimum set of core outcomes for use in future trials of SSD interventions. METHODS/DESIGN The CROSSSD study adopts an international two-round online modified Delphi survey followed by a stakeholder consensus meeting to identify a patient-centred core outcome domain set for SSD based on what is considered critical and important for assessing whether an intervention for SSD has worked. DISCUSSION The resulting core outcome domain set will act as a minimum standard for reporting in future clinical trials and could have further applications in guiding the use of outcome measures in clinical practice. Standardisation will facilitate comparison of research findings.

Abstract
OBJECTIVE To understand the communication and social challenges that individuals with SSD face post diagnosis. METHODS Fifty-two single-sided deaf patients from all over the world participated in semi-structured interviews. Interviews were digitally recorded, transcribed verbatim, and coded using a thematic analysis approach. RESULTS Patients with single sided deafness identified challenges including: increased reliance on family members, decreased sense of autonomy, communication quality changes with family members, information discrepancy across family members and various emotional responses, conflicting information from interactions with multiple medical professionals, and lack of knowledge regarding what to anticipate post diagnosis. CONCLUSION This study provides insights into patients' perspectives around single-sided deafness and its challenges, and the various health care approaches (e.g., patient- and family-centered care, third party disability, patient navigation) that could be implemented post diagnosis to decrease negative experiences and outcomes associated with SSD. PRACTICAL IMPLICATIONS This study has practical implications for improving our understanding of what single-sided deaf patients need and for health professionals to offer better care to current and future populations impacted by single-sided deafness.

Abstract
Sudden sensorineural hearing loss (SSNHL) is most often defined as a rapid hearing loss of ≥ 30 decibels across at least three contiguous audiometric frequencies over a time of ≤ 72 hours. Cupping therapy has been practiced across the world for thousands of years. Cupping therapy is practiced by creating suction inside cups that are placed on predefined skin areas. Our case is a 48-year-old female with a four-year history of Meniere’s disease, recurrent tinnitus, episodes of dizziness attacks, and fullness of the right ear. The patient developed sudden sensorineural hearing loss. She received conventional treatment and wet cupping therapy as a complementary integrative treatment. After the integrative management protocol was completed, pure tone audiometry tests revealed significant hearing improvement across almost all frequencies. To the best of our knowledge, this case presentation is the first reported case of this type. A positive effect of cupping was reported in our case as an integrative complementary treatment. Large, well-designed quality clinical trials to evaluate the efficacy and safety of wet cupping therapy (WCT) as a complementary treatment of SSNHL is highly recommended.

Abstract
Background: Increasing arterial stiffness is associated with atherosclerosis and there is an association between atherosclerosis and tinnitus may occur.Objectives: The aim of this study was to investigate the relationship between arterial stiffness and tinnitus using the central pulse-wave analysis method.Methods: This prospective, single center study included 98 participants, comprising 49 patients diagnosed with subjective idiopathic tinnitus (Group 1) and a control group of 49 healthy subjects (Group 2). The Mobil-O-Graph 24 h Pulse wave analysis (PWA) Monitor (I.E.M. GmbH, Stolberg, Germany) was used to determine the arterial stiffness and cardiovascular hemodynamic parameters. Central pulse pressure (CPP), Augmentation index and pulse wave velocity (PWV) were obtained with the device.Results: No statistically significant difference was determined between Groups in respect of age, smoking and hypertension (p > .05). Statistically significantly higher Central Pulse Pressure (CPP) values and pulse wave velocity were higher in Group 1 compared to the control group (p < .005). No statistical variation was detected in terms of the augmentation index (18.5 ± 11.3 vs 16.7 ± 10.3, p = .543).Conclusion: Our results marked that arterial stiffness is associated with tinnitus. The relationship was examined via oscillometric method, which is simple to perform and has been recommended in guidelines for the determination of cardiovascular event risk.

Abstract
OBJECTIVES Idiopathic sudden sensorineural hearing loss (ISSNHL) is a distressing condition that can significantly affect quality of life. Unilateral ISSNHL, occurring first in 1 ear and then the contralateral ear at a separate and discrete time, is a rare presentation that we refer to as metachronous ISSNHL. Our objective was to characterize the presentation of metachronous ISSNHL and report on management and hearing outcomes. STUDY DESIGN Retrospective case series. SETTING Otology clinic at an academic tertiary referral center. SUBJECTS AND METHODS Patients ≥18 years old presenting with metachronous ISSNHL between April 2008 to November 2017 were identified through review of the clinic electronic medical record. Metachronous ISSNHL was defined as unilateral ISSNHL occurring in temporally discrete episodes (>6 months apart) affecting both ears. Patients with identifiable causes for sudden hearing loss were excluded. Patient demographics, comorbidities, management, and audiologic outcomes were recorded. RESULTS Eleven patients with metachronous ISSNHL were identified out of 558 patients with ISSNHL. In patients with metachronous ISSNHL, the mean ± standard deviation age at the time of ISSNHL in the second ear was 58.6 ± 15.2 years (range, 31-77 years). The mean interval between episodes was 9.6 ± 7.5 years (range, 1-22 years). Patients were treated with systemic and intratympanic steroids with variable hearing recovery; 5 patients with resultant bilateral severe to profound hearing loss underwent successful cochlear implantation. CONCLUSION Metachronous ISSNHL is uncommon. Treatment is similar to ISSNHL, and cochlear implantation can successfully restore hearing in individuals who do not experience recovery.

Abstract
OBJECTIVES We hypothesized that patients with idiopathic sudden sensorineural hearing loss (ISSHL) would have experienced more stress prior to the onset than they typically did. This study investigated stress levels in patients before the onset of ISSHL. MATERIALS AND METHODS Forty-two patients with ISSHL were investigated. We used an original questionnaire to evaluate subjective stress levels in 1 week before onset. Serum hemoglobin A1c (HbA1c) and total cholesterol were examined to evaluate biochemical stress markers reflecting the preceding 1 to 2 months. The results on admission were compared with those at the follow-up visit. RESULTS Significantly more patients reported greater physical exhaustion, greater mental exhaustion, or a worse physical condition on admission than at follow-up (p<0.01, for each variable). On admission, 81% of patients reported greater than normal stress with regard to at least 1 of 3 items. The mean serum HbA1c was slightly but nonsignificantly lower at the follow-up visit (p=0.10), while the mean serum total cholesterol was significantly lower at follow-up than on admission (p<0.01). CONCLUSION The results indicate that patients were under a greater degree of stress before the onset of ISSHL, suggesting that stress plays a role in inducing ISSHL.

Abstract
Sudden sensorineural hearing loss (SSNHL) is a common condition with a rapid onset, and its worldwide frequency is increasing each year. Importantly, a significant number of patients with SSNHL do not respond to initial treatment, which is termed refractory sudden hearing loss (RSHL), and further treatment is not standardized in terms of type, duration, administration route, and concentration of topical steroid therapy. Dexamethasone and methylprednisolone are effective in treating RSHL, and salvage treatment typically consists of 2 weeks of steroid therapy followed by 3–6 months of follow-up. Near-continual steroid perfusion appears to be more effective than intermittent steroid injection. Furthermore, several novel therapeutic regimens have shown promising results in small-scale studies. However, the optimum treatment needs to be confirmed in larger randomized controlled trials.

Abstract
Objective This study explored the relationship between macrophage migration inhibitory
factor (MIF) gene polymorphism (−173G/C) and glucocorticoid sensitivity in
sudden sensorineural hearing loss (SSNHL). Methods A total of 120 patients with SSNHL were divided into a
glucocorticoid-sensitive group and a glucocorticoid-resistant group. A group
of 93 healthy individuals served as the control group. Serum MIF levels of
the participants were measured and MIF genotyping was
performed. Results The frequency of the MIF −173C allele was significantly
higher in glucocorticoid-sensitive patients than in glucocorticoid-resistant
patients. Serum MIF levels were significantly higher in SSNHL patients than
in healthy controls, and higher in the glucocorticoid-sensitive group than
in the glucocorticoid-resistant group of SSNHL patients, which was
unexpected. Compared with patients with the GG genotype, patients with the
−173C allele (GC and CC genotypes) had significantly higher levels of serum
MIF and superoxide dismutase activity and lower levels of tumor necrosis
factor-α and malondialdehyde. Conclusion The MIF −173G/C polymorphism is associated with
glucocorticoid sensitivity in SSNHL patients. The C allele can result in
higher MIF production, reduced oxidative stress, and greater glucocorticoid
sensitivity.

Nutritional Mushroom Treatment in Meniere's Disease with Coriolus versicolor: A Rationale for Therapeutic Intervention in Neuroinflammation and Antineurodegeneration. Int J Mol Sci 2019; 21:E284. [PMID: 31906226 PMCID: PMC6981469 DOI: 10.3390/ijms21010284] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 12/25/2019] [Accepted: 12/27/2019] [Indexed: 12/19/2022] Open
Abstract
Meniere's disease (MD) represents a clinical syndrome characterized by episodes of spontaneous vertigo, associated with fluctuating, low to medium frequencies sensorineural hearing loss (SNHL), tinnitus, and aural fullness affecting one or both ears. To date, the cause of MD remains substantially unknown, despite increasing evidence suggesting that oxidative stress and neuroinflammation may be central to the development of endolymphatic hydrops and consequent otholitic degeneration and displacement in the reuniting duct, thus originating the otolithic crisis from vestibular otolithic organs utricle or saccule. As a starting point to withstand pathological consequences, cellular pathways conferring protection against oxidative stress, such as vitagenes, are also induced, but at a level not sufficient to prevent full neuroprotection, which can be reinforced by exogenous nutritional approaches. One emerging strategy is supplementation with mushrooms. Mushroom preparations, used in traditional medicine for thousands of years, are endowed with various biological actions, including antioxidant, immunostimulatory, hepatoprotective, anticancer, as well as antiviral effects. For example, therapeutic polysaccharopeptides obtained from Coriolus versicolor are commercially well established. In this study, we examined the hypothesis that neurotoxic insult represents a critical primary mediator operating in MD pathogenesis, reflected by quantitative increases of markers of oxidative stress and cellular stress response in the peripheral blood of MD patients. We evaluated systemic oxidative stress and cellular stress response in MD patients in the absence and in the presence of treatment with a biomass preparation from Coriolus. Systemic oxidative stress was estimated by measuring, in plasma, protein carbonyls, hydroxynonenals (HNE), and ultraweak luminescence, as well as by lipidomics analysis of active biolipids, such as lipoxin A4 and F2-isoprostanes, whereas in lymphocytes we determined heat shock proteins 70 (Hsp72), heme oxygenase-1 (HO-1), thioredoxin (Trx), and γ-GC liase to evaluate the systemic cellular stress response. Increased levels of carbonyls, HNE, luminescence, and F2-isoprostanes were found in MD patients with respect to the MD plus Coriolus-treated group. This was paralleled by a significant (p < 0.01) induction, after Coriolus treatment, of vitagenes such as HO-1, Hsp70, Trx, sirtuin-1, and γ-GC liase in lymphocyte and by a significant (p < 0.05) increase in the plasma ratio-reduced glutathione (GSH) vs. oxidized glutathione (GSSG). In conclusion, patients affected by MD are under conditions of systemic oxidative stress, and the induction of vitagenes after mushroom supplementation indicates a maintained response to counteract intracellular pro-oxidant status. The present study also highlights the importance of investigating MD as a convenient model of cochlear neurodegenerative disease. Thus, searching innovative and more potent inducers of the vitagene system can allow the development of pharmacological strategies capable of enhancing the intrinsic reserve of vulnerable neurons, such as ganglion cells to maximize antidegenerative stress responses and thus providing neuroprotection.

Abstract
Non-invasive characterization of micro-vibrations in the tympanic membrane (TM) excited by external sound waves is considered as a promising and essential diagnosis in modern otolaryngology. To verify the possibility of measuring and discriminating the vibrating pattern of TM, here we describe a micro-vibration measurement method of latex membrane resembling the TM. The measurements are obtained with an externally generated audio stimuli of 2.0, 2.2, 2.8, 3.1 and 3.2 kHz, and their respective vibrations based tomographic, volumetric and quantitative evaluations were acquired using optical Doppler tomography (ODT). The micro oscillations and structural changes which occurred due to diverse frequencies are measured with sufficient accuracy using a highly sensitive ODT system implied phase subtraction method. The obtained results demonstrated the capability of measuring and analyzing the complex varying micro-vibration of the membrane according to implied sound frequency.
