Auris Nasus Larynx 2024; 51:11-24. [PMID: 37127508 DOI: 10.1016/j.anl.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/07/2023] [Accepted: 04/17/2023] [Indexed: 05/03/2023]
Abstract
OBJECTIVE Idiopathic sudden sensorineural hearing loss (SSNHL) is typically treated with systematic or intratympanic corticosteroids. Current ENT-UK guidelines suggest treatment with a dose of oral prednisolone 1mg/kg/day for 7 days then tapered over a further 5 days. However, there is no consensus on the effectiveness of corticosteroids for idiopathic SSNHL and no universally accepted optimal regime. The objective of this systematic review was to examine the effect of high dose versus standard dose corticosteroids in the management of idiopathic SSNHL. METHODS A systematic review was performed of all published data related to patients with idiopathic SSNHL who were treated acutely with high dose corticosteroid therapy. Articles were included that reported data on high dose, or comparing standard dose to high dose, oral or intravenous corticosteroid therapy for the treatment of patients with idiopathic sudden sensorineural hearing loss. Articles where patients received only combination treatment with intra-tympanic steroid were excluded. Risk of bias was assessed using the ROBINS-I tool and the ROB-2 tool. RESULTS Six studies were included in the analysis, representing 919 patients. Two prospective single-arm studies of patients with SSNHL treated with a high dose steroid regime found mean hearing level improved (79.5dB to 42.3dB) and 45.8% of idiopathic patients had complete recovery of hearing. Three retrospective case-series comparing high dose to standard dose regimes found a significantly greater improvement in hearing level (38.3dB vs. 48.8dB, P = 0.042), a greater mean absolute hearing gain (44.4dB vs. 15.1dB) and a significantly higher rate of functionally relevant recovery (35.7% vs. 7.4%, P = 0.035) in patients treated with high dose regimes. The single included prospective randomised trial found no statistically significant difference in mean hearing level or speech discrimination score between patients treated with high dose pulse steroids or a standard dose regime. CONCLUSIONS Our systematic review found the reported outcomes in the literature in this area to be mixed, with some studies suggesting a greater degree of hearing recovery with a high dose regime but others suggesting no difference. The overall quality of the available evidence was deemed to be low, with the studies at moderate risk of bias.

Abstract
Oral, intravenous, or intratympanic steroid therapy (ST) are commonly applied methods of pharmacotherapy in Sudden Sensorineural Hearing Loss (SSNHL). There are vast discrepancies on the recommended initial dose and the duration of ST in medical reports. The aim of the research is a retrospective comparison of patients’ examination results with different therapeutical strategies. The medical records of 218 patients treated for SSNHL at the Military Institute of Medicine were subjected to retrospective analysis by comparison of the results of pure tone audiometry prior to and after treatment with steroid therapy (first-dose delay, mass of first dose, duration of treatment). Postponement of implementation of ST to 5 days resulted in a significant improvement of hearing across all frequencies. The implementation of ST sequentially in periods (5th−10th day; >10th day) resulted in a statistically insignificant improvement of hearing in the following frequencies: 250 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 3000 Hz, 4000 Hz. There was a statistical improvement of hearing within all frequencies analyzed for the initial dose of prednisone above 50 mg. For an initial dose below 50 mg, in 4000 Hz, the improvement of hearing was statistically insignificant. The research demonstrated a significant influence of steroid therapy on treatment results in patients with Sudden Sensorineural Hearing Loss.

Abstract
Sudden sensorineural hearing loss (SSNHL) is a true otological emergency that must be diagnosed and treated immediately. This study aimed to assess the efficacy of treatment with intratympanic dexamethasone (ITD) plus oral prednisolone with that of oral prednisolone or intratympanic dexamethasone alone and to determine factor affecting treatment outcome for SSNHL. Forty-five patients with SSNHL that had been present within 2 weeks of onset of symptoms were included in this prospective case control study. Patients were allocated to three different groups. Patients in group A were treated with oral prednisolone 1 mg/kg/d full dose 14 days then tapered over next 14 days. Patients in group B were treated with ITD 0.5 ml (4 mg/ml) every 7 days for a total 4 weeks along with oral prednisolone 1 mg/kg/d in tapering dose for 4 weeks. Patients in group C were got ITD 0.5 ml (4 mg/ml) every 7 days for a total 4 weeks. Audiogram was performed before each subsequent injection and at completion of treatment course. Among all participants, 22 patients (48.89%) showed improvement in pure tone audiogram to within 50% of pre- sudden hearing loss. On comparing the results of group A, B and C, there were no statistically significant difference with each other (p value 0.185). The mean audiometric gain was 37.71 dB in recovered cases. The combination therapy of intratympanic dexamethasone and oral steroid is more effective in comparison with intratympanic or oral steroid alone in the treatment of SSNHL as the patients benefitted from the therapeutic effects of both local and systemic steroids.

Abstract
Background Numerous infections can result in neurological symptoms, including anosmia, facial paralysis, and abrupt sensorineural hearing loss (SSNHL). During the earlier SARS pandemic, coronaviruses were linked to a loss of smell and taste due to brain damage. Purpose To clinically detect corticosteroid treatment effectiveness in SSNHL post-COVID-19 infection and to detect the factors that affect the prognosis for these patients for better diagnosis and earlier management. Subjects and method Subjects included 20 subjects diagnosed by PCR as COVID-19 virus positive, complaining of sudden onset hearing loss post viral infection in different durations. All subjects had basic audiological evaluation done pre-treatment and repeated after 1 week, 2 weeks, and 1 month after treatment with methylprednisolone 21-acetate tablets. Results Onset of hearing loss post-COVID infection ranged from 1 to 3 months. As regards the improvement recognized with treatment course, thirteen patients (65%) of all twenty patients showed complete improvement at 1 month after starting treatment, and seven patients (35%) showed no improvement even after 1 month. Conclusion SSNHL has been widely recognized in the context of COVID-19 to date. Early corticosteroid therapy could help in the recovery of hearing, especially if the beginning of therapy was early in the first 2 weeks.

Abstract
Introduction Oral prednisolone was suggested as the first step to treat idiopathic sudden sensorineural hearing loss (ISSHL). This study aimed to investigate the effect of pulse therapy with methylprednisolone and intratympanic methylprednisolone, compared to traditional oral prednisolone therapy on patients with ISSHL. Material and Methods This randomized control trial included an experimental group receiving 500 mg intravenous methylprednisolone for three sequential days, followed by 1 mg/kg oral prednisolone for 11 days, and intratympanic Depo-Medrol four times twice a week. On the other hand, the control group received 1 mg/kg oral prednisolone for 14 days. Hearing change was assessed through pure tone audiometry. Subsequently, hearing recovery was investigated and analyzed in this study. Result This study was conducted on 51 patients who were divided into two groups of experimental (n=26) and control (n=25). The result revealed no significant difference between the two groups in terms of hearing improvement (P=0.28). Conclusion This revealed no added benefit in pulse steroids combined with intratympanic injections in cases with sudden hearing loss.

Abstract
BACKGROUND In patients with sudden sensorineural hearing loss (SSNHL), steroid therapy is an optional treatment method, but there is controversy about its dose. OBJECTIVE We aimed to compare the efficacy of super-high-dose steroid therapy with that of conventional steroid therapy in patients with profound SSNHL (pSSNHL). MATERIAL AND METHODS Fifty-two patients diagnosed with pSSNHL between March 2010 and May 2017 were divided into the following groups based on their steroid regimen: a conventional steroid regimen (prednisolone at 1.0 mg/kg/day for 10 days) was applied in Group 1, and a super-high-dose steroid regimen (prednisolone at 1.5 mg/kg/day for 14 days) was applied in Group 2. The treatment outcomes were compared between the groups at 2 and 4 weeks after the initial treatment by use of Siegel's criteria. RESULTS Of the 52 patients, 31 were classified into Group 1 and 21 into Group 2. When comparing the proportion of patients in complete or partial recovery by Siegel's criteria, the recovery rate was significantly higher in Group 2 than in Group 1 (19% vs 0%, p = .022 at 2 weeks; 35.7% vs 7.4%, p = 0.035 at 4 weeks). CONCLUSIONS AND SIGNIFICANCE Patients with pSSNHL treated using the super-high-dose steroid regimen demonstrated better recovery rates to serviceable hearing than did those treated using the conventional steroid regimen without significant complications.

Abstract
Sudden sensorineural hearing loss (SSNHL) is an enigmatic entity, with obscure pathophysiology and debatable efficacy of the treatment agents used. An underlying cause is identified in only 10-15% of cases. The management of the remaining patients, classified as 'idiopathic', is empirical, and is conventionally with systemic steroids, vasodilator therapy, rheological agents, and antioxidants, to list a few amongst the host of the agents employed for the treatment. The availability of conflicting outcomes and lack of conclusive evidence has resulted in the propagation of consensus-based treatment protocols. In the present review, we discuss the various controversial issues and newer developments in the management of idiopathic SSNHL. The current review aims to present a narrative outlook of the updated evidence base available from PUBMED, augmented with relevant designated publications.

Abstract
Background: The best way to administer steroids for sudden sensorineural hearing loss (SSHL) is still unclear. The present study was aimed at estimating the efficacy of steroids by intratympanic, systemic, and combined therapy (CT) routes. Methods: A systematic literature search was performed from 1950 to October 2019 for randomized controlled trials comparing the use of intratympanic, systemic, and combined steroid therapy for SSHL. The outcomes of recovery rate and pure tone average (PTA) improvement were assessed by random-effects and fixed-effects meta-analysis. Results: A total of 20 articles identified from 7 countries were eligible for analysis. Although no significant difference in recovery rate was observed between intratympanic steroid therapy (IST) and systemic steroid therapy (SST), IST did demonstrate better hearing improvement, as evidenced by a higher PTA than SST. Compared with SST, CT comprising IST and SST had significant recovery rate improvement. Patients treated with CT had a significantly higher PTA than those treated with SST. Through subgroup analysis based on the equivalent dose of prednisone, it was shown that CT led to a significantly higher PTA than SST only in the high-dose CT versus high-dose SST groups and moderate-dose CT versus high-dose SST groups. Conclusion: Moderate and high dose of CT could accelerate hearing improvement in SSHL.

Cochlear Glucocorticoid Receptor and Serum Corticosterone Expression in a Rodent Model of Noise-induced Hearing Loss: Comparison of Timing of Dexamethasone Administration. Sci Rep 2019; 9:12646.

Abstract
Glucocorticoid (GC) is a steroid hormone secreted from the adrenal cortex in response to stress, which acts by binding to cytoplasmic glucocorticoid receptors (GRs). Dexamethasone (DEX) is a synthetic GC exhibiting immunosuppressive effects in both human and rodent models of hearing loss. While clinical evidence has shown the effectiveness of DEX for treatment of various inner ear diseases, its mechanisms of action and the optimal timing of treatment are not well understood. In the present study, intergroup comparisons were conducted based on the time point of treatment with DEX: (1) pretreatment; (2) posttreatment; and (3) pre&post-noise. The pre&post DEX treatment group showed a significant improvement in threshold shift at 1 day post-noise exposure as compared to the TTS (transient threshold shift)-only group at 8 and 16 kHz. Both TTS and PTS (permanent threshold shift) significantly reduced cochlear GR mRNA expression and increased serum corticosterone and cochlear inflammatory cytokines. The pre&post DEX treatment group showed a significant decrease in serum corticosterone level as compared to other DEX treatment groups and TTS-treated group at 3 days after acoustic trauma. Our results suggest that the timing of DEX administration differentially modulates systemic steroid levels, GR expression and cochlear cytokine expression.

Abstract
PURPOSE The purpose of this study was to describe the role of explorative tympanotomy in patients with Profound Sudden Sensorineural Hearing Loss (SSNHL) without clinical evidence of perilymphatic or labyrinthine fistula and to compare intraoperative findings with the postoperative hearing outcome. STUDY DESIGN Retrospective study of all patients diagnosed with SSNHL who underwent explorative tympanotomy between 2002 and 2005. SETTINGS Tertiary care university-affiliated hospital. SUBJECTS AND METHODS Eighty-two patients were diagnosed with unilateral profound SSNHL and underwent tympanotomy with sealing of the round and oval windows. Values of pure tone audiograms and percentage hearing loss of patients with and without intraoperative diagnosed perilymphatic fistula (PLF) were compared and analyzed. RESULTS PLF was diagnosed in 28% cases intraoperatively. In most cases, hearing improved significantly after surgery. Interestingly, patients with PLF had a 2.4 times greater decrease of percentage hearing loss compared to patients without PLF. CONCLUSIONS Explorative tympanotomy seems to be useful in patients with profound SSNHL. Patients with PLF benefit more from the surgical procedure and have better outcome than patients without PLF.

Abstract
Objective: To evaluate the characteristics and spontaneous recovery of tinnitus related to idiopathic sudden sensorineural hearing loss (ISSNHL). Study Design: Retrospective analysis from two randomized placebo-controlled clinical trials for treatment of ISSNHL within 48 hours from onset (Study A), or of tinnitus related to ISSNHL within 3 months from onset (Study B). Setting: Forty-eight European sites (academic tertiary referral centers, private ENT practices). Patients: One hundred thirteen adult patients of which 65 with hearing loss ≥30 dB (Study A) and 48 with persistent acute tinnitus (Study B) at baseline. Interventions: Intratympanic (i.t.) injection of placebo gel in single dose or in triple dose during 3 consecutive days. Main Outcome Measures: Frequency of tinnitus, subjective tinnitus loudness, rates of complete tinnitus remission, and complete hearing recovery during 3 months follow-up. Results: In acute ISSNHL, tinnitus loudness decreased rapidly in cases of mild-moderate hearing loss, and tinnitus had completely resolved in two-thirds of patients after 3 months. Hearing recovery preceded tinnitus resolution. When associated with severe-profound hearing loss, tinnitus improved significantly less. Complete hearing recovery and full tinnitus remission were both about three times more frequent in mild-moderate hearing loss patients than in severe-profound cases. Improvement in tinnitus loudness over time can be approximated by a negative exponential function. Conclusions: Prognosis for ISSNHL-related tinnitus is relatively poor in case of severe-profound hearing loss and the longer it has persisted. Alleviation or management of tinnitus should be a key therapeutic objective especially in pronounced ISSNHL cases.

Abstract
Background Sudden sensorineural hearing loss (SSHL) is a disease, which severely affects the patient’s social and relational life. The underlying pathomechanisms have not been finally clarified yet and outcome is not predictable. Methods We conducted a retrospective study in order to identify parameters that influence hearing recovery. The data base contains results of basic otoneurological tests and clinical parameters of 198 patients with idiopathic SSHL of at least 60 dB in at least four frequencies, diagnosed and treated at the University Hospital of Münster, Germany, between 1999 and 2015. Hearing recovery was measured by pure tone audiometry. Results Multivariate linear and logistic regression analyses indicate that the chance as well as the magnitude of hearing recovery is higher for patients with normal caloric testing than for patients with pathological caloric testing. However, for the subgroup of patients who attained a hearing recovery, the caloric testing result was not found to influence the magnitude. Instead, the magnitude was noticeably lower for patients within this subgroup who had a previous hearing loss. Furthermore, we found indications that the magnitude is higher for men than for women and that receiving a high-dose steroid therapy is associated with a higher chance and magnitude of a hearing recovery. Conclusions We conclude that SSHL associated with disorders of the vestibular system or previous hearing loss represent special sub-entities of SSHL that may be caused by unique pathophysiological mechanisms and are associated with worse outcome. Furthermore, our data support the importance of elevated dosage of steroids in SSHL therapy.

Abstract
OBJECTIVE The aims of the present study were to investigate the prevalence of cochlear dead regions (DRs) in patients with sudden sensorineural hearing loss (SSNHL) and compare the hearing outcome according to the presence of DRs. STUDY DESIGN Retrospective chart review. SETTING Tertiary referral center. PATIENTS AND METHODS The threshold-equalizing noise (HL) test was performed on a total of 112 ears diagnosed with SSNHL. Ears were divided into two groups based on the presence of DRs. Eighty-two ears belonged to the group without DRs and 30 ears belonged to the group with DRs. There was no difference between the two groups with respect to age, sex, side of affected ear, presence of bilateral SSNHL, presence of vertigo, history of treatment, and initial pure-tone thresholds. Pure-tone audiograms were gathered at the time of initial presentation and at 1, 3, and 6 months after onset of symptoms. RESULTS The prevalence of DRs was observed to be 29% and was found to be prevalent at 1k and 1.5k Hz in patients with SSNHL. When the hearing thresholds over times were compared between the two groups, subjects with DRs showed significantly poorer hearing outcome compared with those without DRs. The improvements in word recognition scores over times were also less in subject with DRs than those without DRs. CONCLUSION DRs are associated with worse hearing thresholds at follow-up audiogram and might be associated with unfavorable hearing outcome in patients with SSNHL.

Abstract
OBJECTIVE To assess possible delayed recovery of the maximum speech discrimination score (SDS) when the audiometric threshold ceases to change. METHODS We retrospectively examined 20 patients with idiopathic sudden sensorineural hearing loss (ISSNHL) (gender: 9 males and 11 females, age: 24-71 years). The findings of pure-tone average (PTA), maximum SDS, auditory brainstem responses (ABRs), and tinnitus handicap inventory (THI) were compared among the three periods of 1-3 months, 6-8 months, and 11-13 months after ISSNHL onset. RESULTS No significant differences were noted in PTA, whereas an increase of greater than or equal to 10% in maximum SDS was recognized in 9 patients (45%) from the period of 1-3 months to the period of 11-13 months. Four of the 9 patients showed 20% or more recovery of maximum SDS. No significant differences were observed in the interpeak latency difference between waves I and V and the interaural latency difference of wave V in ABRs, whereas an improvement in the THI grade was recognized in 11 patients (55%) from the period of 1-3 months to the period of 11-13 months. CONCLUSION The present study suggested the incidence of maximum SDS restoration over 1 year after ISSNHL onset. These findings may be because of the effects of auditory plasticity via the central auditory pathway.

Abstract
BACKGROUND High-dose corticosteroids are currently recommended for idiopathic sudden sensorineural hearing loss (ISSNHL) treatment. Intratympanic injections (ITI) are of growing importance, especially in cases of therapy resistance. The selection of patients for this procedure in SSNHL has not been adequately examined so far. STUDY DESIGN A total of 77 patients with ISSNHL after ineffective systemic pretreatment underwent intratympanic administration of dexamethasone and hyaluronic acid. Improvement after treatment was determined by pure tone audiometry for both ears before and of the treated ear after ITI. RESULTS In this study 34 female and 43 male patients with mean age of 57 years showed a pre-ITI hearing loss of 35 dB in the lower frequencies and 69 dB in the higher frequencies. The mean hearing gain was 10 dB and the response rate was 62%. Absolute hearing gain revealed significant improvements at 500 Hz, 1 kHz and 2 kHz. Under inclusion of contralateral thresholds there were hardly any differences up to 4 kHz. In a detailed analysis of responders moderate improvements could be observed even in higher frequencies. Overall, no relevant adverse events occurred. CONCLUSION Treatment of ISSNHL resistant to systemic regimens by ITI of steroids provides an option that offers additional prospects of auditory improvement for affected patients. The presented results indicate that these modalities are also valid for patients with pancochlear ISSNHL.

Abstract
We aimed to compare the treatment outcomes and the occurrence rates of adverse events associated with different steroid regimens in geriatric patients (aged 65 years or older) with unilateral idiopathic sudden sensorineural hearing loss (ISSNHL). After thorough medical chart reviews of 109 patients with ISSNHL between May 2006 and December 2013, we performed a propensity score-matched analysis using previously known prognostic factors, steroid regimens, and other cointerventions. Patients were divided based on their steroid regimens into group I (which initially received 48 mg of methylprednisolone daily with a subsequently tapered dose) and group II (which initially received 24 mg of methylprednisolone daily with a subsequently tapered dose). We compared final hearing and the occurrence of adverse events between the two groups. As a result, 20 pairs of propensity score-matched patients (n = 40) were enrolled. Group I patients showed better final hearing levels compared with group II patients (42.00±22.35 dB and 57.38±26.40 dB, respectively), although this difference was marginally significant (p = 0.058). Based on the comparative analysis of each of the frequencies in the final audiograms, lower hearing thresholds at 2 KHz were observed in group I (p = 0.049). There was no significant difference in the occurrence of adverse effects between the two groups (p>0.05). In conclusion, conventional steroid regimens produced adverse event occurrence rates that were similar to those of low-dose treatment but may also have produced superior hearing recovery. The use of steroid dose reduction in geriatric patients with ISSNHL is not preferable to conventional steroid regimens.

Abstract
Background Glucocorticoids (GCs) are widely used to treat sudden sensorineural hearing loss (SSNHL) and significantly improve hearing. However, GC insensitivity has been observed in some patients of SSNHL. Objective To study the correlation between GR expression in peripheral blood mononuclear cells (PBMCs) and in the cochlea of guinea pigs at mRNA and protein levels. Methods One group of guinea pigs received dexamethasone (10 mg/kg/day) intraperitoneally for 7 consecutive days (dexamethasone group), and another group of guinea pigs received normal saline (control group). Real time PCR and Western blotting were used to detect the expression of GR mRNA and GR protein in PBMCs and the cochleae. Results The GR mRNA and GR protein were detected in both PBMCs and the cochlear tissue of guinea pigs. GR mRNA and GR protein levels in PBMCs were positively correlated with those in the cochlea. The expression of GR mRNA and GR protein was significantly increased in the dexamethasone group compared to the control group. Conclusions Levels of GR mRNA and GR protein in the PBMCs were positively correlated with those in the cochlea of guinea pigs. Systemic dexamethasone treatment can significantly up-regulate GR expression in PBMCs and in the cochlea. Measurement of the GR level in PBMCs could be used as an indicator of GR level in the cochlea.

Abstract
Background and Objectives Sudden sensorineural hearing loss (SSNHL) is commonly defined as a loss of at least 30 dB in three contiguous frequencies occurring within 3 days. Systemic steroid administration has become the most widely accepted treatment option for SSNHL. Since viral infection and vascular compromise are considered specific causes of SSNHL, antiviral agents, anticoagulants, and stellate ganglion block have been used for its treatment, although the evidence of their effectiveness is weak. The present study evaluated the hearing recovery rate in the combination therapy group (systemic steroids, antiviral agent, anticoagulants, and stellate ganglion block) in comparison with patients treated with systemic steroids alone. Subjects and Methods A total of 85 patients diagnosed with SSNHL were treated with combination therapy (group A, 46 patients) or systemic steroids only (group B, 39 patients). Hearing improvement was defined as a hearing gain of more than slight improvement using Siegel's criteria. All patients were treated with a 10-day course of systemic steroids (10-mg dexamethasone for 5 days, followed by tapering for 5 days). Acyclovir, heparin, and stellate ganglion block were included in the group A treatment regimen. Results The overall rate of hearing improvement was 60.9% (28/46 patients) in group A, which was significantly higher than that (38.5%, 15/39 patients) in group B. The distribution of prognostic factors was not significantly different between the two groups with the exception of the degree of initial hearing loss, which was more severe in group A. Upon analysis according to prognostic factors, group A showed a better hearing improvement recovery rate than group B in patients with hearing loss >70 dB, age >41 years, dizziness, and early treatment (<1 week). Conclusions Thus SSNHL patients treated with combination therapy have a higher likelihood of hearing improvement than those treated with systemic steroids alone.

Abstract
The study purpose was to determine the efficacy of steroids, volume expanders and antivirals in the management of idiopathic sudden sensory neural hearing loss and to establish importance of early medical intervention. In this prospective study, thirty-four patients presenting with idiopathic sudden hearing loss of 30 db or more were enrolled in study group between 2005 and 2009. Patient variables as they related to recovery were studied and include patient age, time to onset of therapy, status of contralateral ear, presence of diabetes, severity of hearing loss, pattern of hearing loss in audiogram and presence of associated symptoms, (tinnitus, vertigo). Treatment protocol with intravenous hydrocortisone, intravenous dextran and oral anti-viral agent was followed. Pre-treatment and post-treatment pure tone average was analyzed. With combination therapy the overall improvement in pure tone threshold was seen in 27 patients (79.4%). A statistically significant association was found between the time at which medical intervention was started and hearing improvement. Early intervention in patients presenting before 3 days has given 77.8% complete type 1 recovery Idiopathic sudden sensory neural hearing loss is a medical emergency. It should not be misdiagnosed. Early detection and management with volume expanders, steroids and antivirals will improve the chances of complete recovery.

Abstract
Idiopathic sudden sensorineural hearing loss is an unexplained unilateral hearing loss with onset over a period of less than 72 hours, without other known otological diseases. We present a consensus on the diagnosis, treatment and follow-up of this disease, designed by AMORL, after a systematic review of the literature from 1966 to June 2010. Diagnosis of sudden sensorineural hearing loss is based on mandatory otoscopy, acoumetry, tonal audiometry, speech audiometry, and tympanometry. After clinical diagnosis is settled, and before treatment is started, a full analysis should be done and an MRI should be requested later. Treatment is based on systemic corticosteroids (orally in most cases), helped by intratympanic doses as rescue after treatment failures. Follow-up should be done at day 7, with tonal and speech audiometries, and regularly at 15, 30, and 90 days after start of therapy, and after 12 months. By consensus, results after treatment should be reported as absolute dBs recovered in pure tonal audiometry, as improvement in the recovery rate in unilateral cases, and as improvement in speech audiometry.

Abstract
AbstractBackground:The management of sudden sensorineural hearing loss has not yet been standardised. Hyperbaric oxygen therapy influences recovery from sudden sensorineural hearing loss, but the underlying mechanism is unknown and the appropriate indications and protocols undetermined.Materials and methods:Nineteen patients affected by sudden sensorineural hearing loss were treated after unsuccessful medical therapy, either in an acute or chronic setting. Pure oxygen inhalation at 2.5 atmospheres absolute pressure was administered for 90 minutes, for 30 sessions. Frequency-specific and average pure tone hearing thresholds were determined before and after hyperbaric oxygen therapy. The number of hyperbaric oxygen therapy sessions, the patient's age and any therapeutic delay were considered as quantitative variables possibly influencing outcome. Stepwise multivariate analysis was performed.Results:Salvage hyperbaric oxygen therapy appeared to improve patients' pure tone hearing thresholds, particularly at low frequencies. Positive results were more likely with increased patient age and reduced delay in receiving hyperbaric oxygen therapy.Conclusion:Hyperbaric oxygen therapy has a strong scientific rationale, and improves pure tone hearing thresholds in cases of sudden sensorineural hearing loss unresponsive to medical therapy. Further research may be able to identify those patients with sudden sensorineural hearing loss for whom hyperbaric oxygen therapy would be most cost-effective.

Abstract
INTRODUCTION Occasionally, patients with malabsorption represent a diagnostic challenge. Double-balloon enteroscopy (DBE) allows deep and detailed examination of the small bowel. AIM To determine the diagnostic value of DBE in patients with malabsorption of unclear origin. METHODS DBE was performed in a total of 12 patients with clinical malabsorption. Biopsy specimens were taken from macroscopic lesions or from examined small bowel at three different levels of scope insertion depth. Tissue specimens were evaluated with standard hematoxylin and eosin, the modified Marsh classification and, when indicated, special stains for amyloidosis. RESULTS Fifteen DBEs were successfully performed in 12 patients without complications. DBE with small bowel biopsies yielded a diagnosis in 8 patients (67%). A new diagnosis was reached in 4 patients (33%). The new diagnoses included: Crohn's disease, primary intestinal lymphangiectasia and jejunal amyloidosis. In none of these 4 patients did the duodenal biopsies yield a diagnosis. Also, DBE excluded enteropathy-associated T-cell lymphoma (EATL) and/or ulcerative jejunitis in symptomatic celiac disease patients. CONCLUSIONS DBE had a diagnostic value of 42% in patients with malabsorption of unclear origin. In addition, DBE was useful to rule out complications of long-standing celiac disease such as ulcerative jejunitis or EATL. DBE should be reserved for patients with unexplained malabsorption. DBE with jejunal and ileal biopsies appears to have a diagnostic value in patients with malabsorption, even when duodenal biopsies are histologically normal.
