Abstract
INTRODUCTION Girls and women with Turner syndrome (TS) present with multiple ear and hearing problems, ranging from external morphologic abnormalities to sensorineural or conductive hearing loss. The exact pathophysiology behind these otological diseases is not yet completely understood. The aim of this study is to provide a systematic review on the prevalence of otological disease in TS. METHODS We conducted a systematic review according to the PRISMA guidelines. A database search was performed in PubMed, Embase, Web of Science, and Cochrane library. RESULTS The prevalence of otological disease as external ear deformities (20-62%), recurrent otitis media (24-48%), and hearing loss (36-84%) is high in TS. The auditory phenotype in TS is complex and seems to be dynamic with CHL due to middle ear disease at young age and sensorineural hearing loss later in life. CONCLUSION This systematic review of the literature confirms that otological disease is definitely part of the widely variable phenotype in Turner patients. Strong evidence is lacking on the exact prevalence numbers, emphasizing the need for more prospective data gathering. Growing insights in its pathophysiology will help in the understanding and management of hearing problems in TS across lifespan.

Abstract
Sudden sensory neural hearing Loss (SSNHL) needs to be identified and managed correctly in a secondary or tertiary centre. Whilst 45% of presentations are said to be idiopathic in nature, several viruses have been linked to its aetiology. It was noted, anecdotally, that more patients were presenting with SSNHL during the COVID-19 pandemic to our ENT service at Wrightington Wigan and Leigh teaching hospitals, UK (WWL). We identified 4 COVID-19 positive patients who presented to our ENT service with SSNHL. Despite normal findings on external ear examination, three of the patients showed bilateral hearing loss, whilst one had a predominantly unilateral loss. Given our findings we would like to present these four cases, as well as providing hypotheses on possible aetiology of this association. This may aid in research, diagnosis and treatment of future COVID positive patients with SSNHL.

Abstract
Dizziness occurs in children with an estimated prevalence of 0.45% to 15.0%. Vestibular disorders in the pediatric population can impact gross motor function development, visual acuity, and contribute to psychological distress. Appropriate case history and focused direct examination can be helpful when determining the etiology of dizziness. Vestibular testing can be completed in children and guide management of suspected vestibular dysfunction. Vestibular dysfunction is commonly seen in patients with sensorineural hearing loss. Migraine disorders are the most common cause of dizziness in childhood. Etiologies of dizziness in children differ from those commonly seen in adults.

Abstract
Purpose The objective of this cross-sectional study was to determine if there is a potential link between COVID-19 infection and hearing loss. Methods The prospective study was conducted in the COVID Hospital Clinical Centre Niš, Serbia. We performed tonal audiometry and used a custom questionnaire and medical histories to determine the incidence of hearing loss in COVID-19 positive patients. Results There were 74 patients with COVID-19 that met the inclusion criteria of this study and they composed our experimental group. Fifty-four (73%) were men and 20 (27%) women. There were 30 (40.5%) patients with hearing loss. Seventeen patients had unilateral and 13 had bilateral hearing loss. Significant differences between hearing loss groups and control group were found across all age groups, but not at all frequencies. No important differences were found when unilateral hearing loss and bilateral hearing loss groups were compared. There were no significant differences in distributions of comorbidities between the patients with hearing loss and normal hearing patients. Conclusions We found that 30 (40.5%) of the COVID-19 positive patients had sensorineural type of hearing loss. Across all age groups, there were statistically significant differences in frequencies between the COVID-19 positive patients and the control group. There were no significant differences in distributions of comorbidities between the patients with hearing loss and normal hearing patients. Distribution of unilateral and bilateral hearing loss and audiogram types was also not significantly different between the age groups.

Abstract
Hearing loss is one of the most common congenital diagnoses, recognized in large part by a robust newborn hearing screening program. Ensuring appropriate follow-up of failed newborn hearing screening is crucial to avoid delay in initiation of treatment for hearing loss. The most common etiology for congenital hearing loss is genetic, but some cases can be acquired. Understanding of the etiology aids in counseling for the family and in direction of treatment. Early diagnosis and treatment results in dramatically improved speech and developmental outcomes for affected children. Treatment including amplification, speech therapy, adaptations in the classroom, and family support leads to gains in academic performance, parental satisfaction, and quality of life. Early cochlear implantation has been shown to be beneficial in obtaining speech and language skills in patients with severe to profound sensorineural hearing loss and should be considered in the appropriate patient population.

Abstract
Reactive oxygen species (ROS) produced by NADPH oxidases (Nox) contribute to the development of different types of sensorineural hearing loss (SNHL), a common impairment in humans with no established treatment. Although the essential role of Nox3 in otoconia biosynthesis and its possible involvement in hearing have been reported in rodents, immunohistological methods targeted at detecting Nox3 expression in inner ear cells reveal ambiguous results. Therefore, the mechanism underlying Nox3-dependent SNHL remains unclear and warrants further investigation. We generated Nox3-Cre knock-in mice, in which Nox3 was replaced with Cre recombinase (Cre). Using Nox3-Cre;tdTomato mice of either sex, in which tdTomato is expressed under the control of the Nox3 promoter, we determined Nox3-expressing regions and cell types in the inner ear. Nox3-expressing cells in the cochlea included various types of supporting cells, outer hair cells, inner hair cells, and spiral ganglion neurons. Nox3 expression increased with cisplatin, age, and noise insults. Moreover, increased Nox3 expression in supporting cells and outer hair cells, especially at the basal turn of the cochlea, played essential roles in ROS-related SNHL. The extent of Nox3 involvement in SNHL follows the following order: cisplatin-induced hearing loss > age-related hearing loss > noise-induced hearing loss. Here, on the basis of Nox3-Cre;tdTomato, which can be used as a reporter system (Nox3-Cre+/-;tdTomato+/+ and Nox3-Cre+/+;tdTomato+/+), and Nox3-KO (Nox3-Cre+/+;tdTomato+/+) mice, we demonstrate that Nox3 inhibition in the cochlea is a promising strategy for ROS-related SNHL, such as cisplatin-induced HL, age-related HL, and noise-induced HL.SIGNIFICANCE STATEMENT We found Nox3-expressing regions and cell types in the inner ear, especially in the cochlea, using Nox3-Cre;tdTomato mice, a reporter system generated in this study. Nox3 expression increased with cisplatin, age, and noise insults in specific cell types in the cochlea and resulted in the loss (apoptosis) of outer hair cells. Thus, Nox3 might serve as a molecular target for the development of therapeutics for sensorineural hearing loss, particularly cisplatin-induced, age-related, and noise-induced hearing loss.

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
Coronavirus disease 2019 (COVID-19) is an infectious respiratory disease caused by the severe acute respiratory syndrome coronavirus 2, brings with it a plethora of health concerns. Although most people have mild symptoms, which are respiratory in nature, some experience neurological symptoms, central nervous system manifestations, peripheral nervous manifestations, and skeletal muscle manifestations. But the damaging impact of COVID-19 virus on the hearing organs in the inner ear is a new finding yet to be explored. Currently, there is little evidence published connecting novel coronavirus and tinnitus directly. But according to the American Tinnitus Association, preexisting behavioral conditions make it more likely for patients to experience tinnitus due to the stress and depression associated with social isolation and infection avoidance. Hearing loss and Tinnitus is a common pathology seen in otolaryngology and there are numerous papers in literature describing its associations with other infections. However, this is the first reported case of hearing loss and tinnitus in a COVID-19 patient, in the State of Qatar, and this case report strives to contribute to the ocean of literature highlighting the need for otorhinolaryngologists to be aware of its correlation with COVID-19 virus.

Abstract
BACKGROUND Aging, noise, infection, and ototoxic drugs are the major causes of human acquired sensorineural hearing loss, but treatment options are limited. CRISPR/Cas9 technology has tremendous potential to become a new therapeutic modality for acquired non-inherited sensorineural hearing loss. Here, we develop CRISPR/Cas9 strategies to prevent aminoglycoside-induced deafness, a common type of acquired non-inherited sensorineural hearing loss, via disrupting the Htra2 gene in the inner ear which is involved in apoptosis but has not been investigated in cochlear hair cell protection. RESULTS The results indicate that adeno-associated virus (AAV)-mediated delivery of CRISPR/SpCas9 system ameliorates neomycin-induced apoptosis, promotes hair cell survival, and significantly improves hearing function in neomycin-treated mice. The protective effect of the AAV-CRISPR/Cas9 system in vivo is sustained up to 8 weeks after neomycin exposure. For more efficient delivery of the whole CRISPR/Cas9 system, we also explore the AAV-CRISPR/SaCas9 system to prevent neomycin-induced deafness. The in vivo editing efficiency of the SaCas9 system is 1.73% on average. We observed significant improvement in auditory brainstem response thresholds in the injected ears compared with the non-injected ears. At 4 weeks after neomycin exposure, the protective effect of the AAV-CRISPR/SaCas9 system is still obvious, with the improvement in auditory brainstem response threshold up to 50 dB at 8 kHz. CONCLUSIONS These findings demonstrate the safe and effective prevention of aminoglycoside-induced deafness via Htra2 gene editing and support further development of the CRISPR/Cas9 technology in the treatment of non-inherited hearing loss as well as other non-inherited diseases.

Abstract
Rehabilitating hearing loss is highly important due to its positive impact on the ability to understand speech, and the related consequences on family, social and work communication abilities. Children with hearing loss have learning difficulties that adversely affect speech and language acquirement. Most patients with hearing loss can use conventional hearing aids that are partially or completely placed in the external ear canal. Middle ear implants are used when conventional hearing aids are not suitable due to medical reasons, mainly diseases of the external ear canal and the tympanic membrane. The external component of the middle ear implant digitally translates the acoustic information (sound waves) to the implanted part, where the digital information is back-translated to mechanical information (vibrations) which vibrates the ossicle to which it is attached. We present a patient who underwent a Vibrant Soundbridge implantation after unsuccessfully using hearing aids due to recurrent otitis externa. The patient's hearing improved significantly. We conclude that middle ear implants can be an effective treatment for patients who cannot use conventional hearing aids.

Abstract
Patients with otosclerosis can suffer from different grades of combined hearing loss. In addition to surgery (stapedectomy), conventional hearing aids can be used in the treatment of otosclerosis. In cases of severe conductive components in addition to sensorineural hearing loss, treatment with normal hearing aids can be difficult or impossible. In these patients, implantable hearing systems such as cochlear implants represent a possible alternative. The totally implantable Carina middle ear system can be used in patients with even high-grade sensorineural hearing loss. Based on two exemplary cases, the option of using the Carina system in otosclerosis patients and post-implantation results are reported.

Abstract
Two hundred and fifty years have passed since the birth of Ludwig van Beethoven, and the enigma about his hearing loss and overall health status seems to be not completely solved. However, the admission to the hospital of a 64-year-old woman in 2018 with symptoms extremely similar to those experienced by the great composer may add further evidence to a theory previously underestimated. The health issues of the modern patient were found to be due to chronic lead intoxication. The lead was released during daily cooking using a ceramic-coated frying pan with worn surface that poisoned her breakfast most probably for years. Abdominal pain, asthenia, and hearing loss affecting the high frequencies with a many impact on speech intelligibility tormented the patient, as they had Beethoven. An extensive review of the music and medical literature was performed, as well as re-examination of manuscripts, correspondence, and autopsy reports of the famous composer; and great similarities have been found. The soundness of the most-cited classical theories about Beethoven's hearing loss will be discussed. After close scrutiny of the theories, our analysis points toward a progressive sensorineural hearing loss due to lead intoxication as the most probable cause of not only Beethoven's hypoacusis but his overall health status as well. Laryngoscope, 131:179-185, 2021.

Abstract
BACKGROUND AND PURPOSE Idiopathic sudden sensorineural hearing loss is an acute unexplained onset of hearing loss. We examined the central auditory pathway abnormalities in patients with unilateral idiopathic sudden sensorineural hearing loss using diffusion spectrum imaging and the relationships between hearing recovery and diffusion spectrum imaging parameters. MATERIALS AND METHODS Forty-eight patients with unilateral idiopathic sudden sensorineural hearing loss with a duration of ≤2 weeks (range, 8.9 ± 4.3 days) and 20 healthy subjects underwent diffusion spectrum imaging tractography. Hearing levels were evaluated using a pure-tone average at initial presentation and 3-month follow-up. Clinical characteristics and MR imaging findings were assessed. RESULTS Compared with healthy control subjects, the generalized fractional anisotropy values of patients decreased significantly in the bilateral posterior limbs of the internal capsule, with no differences between the ipsilateral and contralateral sides. The quantitative anisotropy values decreased in the Brodmann area 41, contralateral medial geniculate body, bilateral lateral lemniscus, anterior limb of internal capsule, middle temporal gyrus, and anterior corona radiata. Furthermore, at 3-month follow-up, 14 patients had <15 dB of hearing gain. Receiver operating characteristic curve analysis demonstrated that generalized fractional anisotropy in the ipsilateral medial geniculate body was related to prognosis (sensitivity = 64.7%; specificity = 85.7%; area under the curve = 0.796, 95% CI, 0.661-0.931; P < .01). CONCLUSIONS Diffusion spectrum imaging can detect abnormalities of white matter microstructure along the central auditory pathway in patients with unilateral idiopathic sudden sensorineural hearing loss. The generalized fractional anisotropy value of the ipsilateral medial geniculate body may help to predict recovery outcomes.

Abstract
To describe the audio-vestibular disorders related to the newly SARS-CoV-2 infection, including the possible ototoxicity side-effects related to the use of drugs included in the SARS-CoV-2 treatment protocols. A systematic review was performed according to the PRISMA protocol. The Medline and Embase databases were searched from March 1, 2020 to April 9, 2021. Initially the search yielded 400 manuscripts, which were reduced to 15, upon the application of inclusion criteria. Sensorineural hearing loss (SNHL) is the most frequent audio-vestibular symptom described, occurring alone or in association with tinnitus and vertigo. The etiopathogenesis of the inner ear disorders related to COVID-19 infection is still poorly understood. The number of reports of COVID-19 infections associated to audio-vestibular disorders is increasing; even if the quality of the studies available is often insufficient, audio-vestibular disorders should be considered as possible manifestations to be included among the symptoms of this infection.

Abstract
OBJECTIVES AND MAIN OUTCOME MEASURES To determine the prevalence of sensorineural hearing loss (SNHL) attributable to sickle cell disease (SCD) in the global adult population and to identify factors contributing to its severity. STUDY DESIGN Systematic Review and Meta-analysis. METHODS We performed a comprehensive literature search for scientific articles in PubMed, Scopus, CINAHL, Web of Science, and the Cochrane Library that reported the incidence of hearing loss in populations over 18 years of age with SCD. RESULTS We identified 138 studies from the initial search, 12 of which met inclusion criteria and were utilized for data analysis. A total of 636 SCD patients and 360 controls were included in the Cochrane Review Manager 5.3 meta-analysis. There was a statistically significant increase in the prevalence of SNHL in adults with SCD compared with the general population with a cumulative risk ratio (RR) of 6.03. CONCLUSIONS This is the first systematic investigation of the relationship between SCD and SNHL in adult patients across the globe. SNHL is more prevalent in patients with SCD, specifically those of the HbSS genotype, than the general population likely due to the pathophysiology of the disease and its effects on labyrinthine microvasculature. The increased prevalence of SNHL in the adult SCD population warrants future research into the predictors of SNHL severity and merits routine audiometric monitoring of adult SCD patients.

Abstract
PURPOSE To report on failures related to active middle ear implants (AMEI) surgery, within a series of subjects treated at a single Implanting Center. METHODS A retrospective review of 79 cases of implanted AMEI has been performed to report the failure ratio, the causes for the failure and the selected rehabilitative solution. The AMEI included 25 Vibrant Soundbridge® (Medel, Innsbruck, Austria), 20 as round window vibroplasty (RW-VSB) for mixed hearing loss, 5 as incus-vibroplasty for sensorineural hearing loss; 7 MET/Carina® (Cochlear, Melbourne, Australia), 2 MET for mixed and sensorineural hearing loss, 5 Carina for sensorineural hearing loss; 43 Esteem® (EnvoyMedical, St Paul, USA) for sensorineural hearing loss; 3 Maxum® (Ototronics, Texas, USA) for sensorineural hearing loss; 1 Codacs® (Cochlear, Melbourne, Australia) for severe mixed hearing loss. RESULTS The overall complication rate affected 20% of the implanted devices, individually ranging from 6.9 to 100%. Hardware system failures were recorded in all the AMEI, ranging from 10 to 50%. The alternative auditory rehabilitation included replacement of the same system in 2 cases, use of a conventional hearing aid in 3 cases, Cochlear implantation in 4 cases and implantation in the contralateral ear in 2 cases. CONCLUSION The present clinical experience showed that, in spite of the successful functional rate displayed by the majority of the AMEI implantees, complications may occur to a certain percentage of cases and should prompt the professionals to select alternative solutions, starting from the (re)adoption of a conventional hearing aid and ending up to Cochlear implantation.

Abstract
BACKGROUND Hearing loss (HL) in children may adversely affect their development. HL is more prevalent in patients with chronic kidney disease (CKD) than in the general population. This study evaluated the prevalence of HL and its underlying diseases in patients with childhood-onset in CKD. METHODS In this retrospective study of a tertiary referral center, childhood-onset CKD patients (stage 2-5, age at onset of renal symptom < 18 years) were recruited. We referred to the "renal" syndromic HL as cases with genetic or syndromic diseases, or extra-renal anomalies in addition to HL and CKD. RESULTS A total of 421 patients (male:female = 279:142) were reviewed according to the causes of CKD: congenital anomalies of the kidney and urinary tract (CAKUT; n = 184, 43.7%), glomerulopathies (GP; n = 105, 24.9%), cystic kidney diseases (CYST; n = 39, 9.3%), perinatal problems (PP; n = 29, 6.9%), and others (n = 64, 15.2%). HL was detected in 82 (19.5%) patients, including 51 (12.1%) patients with sensorineural hearing loss (SNHL), 30 (7.1%) with conductive hearing loss (CHL), and 1 patient with mixed HL. The prevalence of HL in each group was as follows: 16.8% in the CAKUT group, 28.6% in the GP group, 12.8% in the CYST group, 24.1% in the PP group, and 14.1% in the others group. HL was more common in higher CKD stages, especially CHL in end-stage renal disease. SNHL was more prevalent in CKD from GP. Of the 82 patients with HL, 50% had renal syndromic HL: 58.8% of SNHL and one-third of CHL were renal syndromic HL. CONCLUSION One-fifth of the childhood-onset CKD had HL. Collectively, renal syndromic HL comprised half of the HL in this study. To improve the quality of life in patients with childhood-onset CKD, we suggest that HL should be considered, requiring surveillance, and if necessary, early intervention.

Abstract
Hearing loss is frequently seen in mucopolysaccharidoses (MPS) patients. Although hematopoietic cell transplantation (HCT) increases overall survival, disease progression is observed in certain tissues. This study describes the course of hearing loss (HL) over time in transplanted MPS patients. Transplanted MPS patients between 2003 and 2018 were included and received yearly audiological evaluation, including auditory brainstem response (ABR) or pure tone audiometry (PTA). Twenty-eight MPS-1 and four MPS-6 patients were analyzed with a median follow-up of 5 years (range 11 months-16 years). Air conduction threshold improved significantly over time (P < .001) with a PTA 1-year post-HCT of 50 ± 0.7 dB to 23 ± 11 dB 13 years post-HCT. Bone conduction threshold worsened with a PTA 1 year post-HCT of 10 ± 7 dB to 18 ± 9 dB 13 years post-HCT (P = .34). The degree of HL varied from mainly mild-severe early after HCT to normal-mild at longer follow-up. The type of HL consisted of mainly conductive in the first years post-HCT in contrast to mainly sensorineural at longer follow-up. MRIs of the cerebellopontine angle did not show abnormalities. HL is still seen in patients with MPS despite HCT and consists of a conductive type early after HCT in contrast to a sensorineural type at longer follow-up in the majority of cases. Yearly follow-up of HL is necessary to timely intervene, as hearing is important in the speech and language development of children and their academic achievements.

Abstract
PURPOSE To determine the severity and nature of audiometric threshold shifts for patients with pulsatile tinnitus (PT) due to sigmoid sinus wall anomalies (SSWA). MATERIALS AND METHODS 38 patients with SSWAs and available pre-operative audiograms were examined. Low- and high-frequency pure tone averages (LF-PTA, HF-PTA) were calculated. Audiometric data were compared between affected and unaffected ears, with the interaural difference (affected-unaffected PTA) representing the change in hearing due to PT. Additionally, post-operative change was examined in 14 patients with available data. RESULTS The average pre-operative air conduction (AC) LF-PTA was 17.04 dB on the affected side and 11.38 dB on the unaffected side (p < 0.001). The mean AC HF-PTA was significantly higher on the affected side as well (16.45 dB vs. 14.08 dB, p = 0.008). All shifts were sensorineural, with no significant air-bone gaps, and most subjects still had low-frequency thresholds in the normal range. Though the post-op change was not significant due to attrition, 5/14 patients (35.7%) had complete resolution of their pre-op interaural difference. A similar number developed a HF-PTA post-op threshold elevation in the surgical ear. CONCLUSIONS PT due to SSWAs causes a mean 6 dB low-frequency bone-conduction threshold elevation, and smaller high-frequency threshold shifts, due to masking. Patients with larger threshold shifts should have other potential causes of hearing loss explored. LEVEL OF EVIDENCE Level IV.

Abstract
Epstein syndrome is a rare disease characterized by macrothrombocytopenia, nephritis and progressive sensorineural hearing loss (SNHL). This syndrome is presently recognized as an autosomal dominant disease caused by mutations of non-muscle myosin heavy chain 9 (MYH9). Little information is available about the progress of SNHL, the efficacy of cochlear implants (CI) or the perioperative management of thrombocytopenia in patients with Epstein syndrome. We herein report a case of a patient with Epstein syndrome with the MYH9:c.2105G>A:p.R702H variant who underwent cochlear implantation after 27 years of follow-up for her progressive SNHL. The deterioration rates of hearing were 3.48 dB/year on the right ear and 2.46 dB/year on the left ear. The patient derived benefits from CI and had a speech recognition test result (for sentences) of 93% at 6-months postoperatively. Thrombocytopenia was successfully managed without any bleeding complications by using eltrombopag, an oral thrombopoietic agent, making transfusion of platelets unnecessary. The accurate diagnosis of Epstein syndrome was made only after long-term follow-up as the thrombocytopenia was initially diagnosed as idiopathic thrombocytopenic purpura. This case report highlights the perioperative management of thrombocytopenia, the progress of SNHL and the potential pitfalls of diagnosis.

Abstract
RMND1 (required for meiotic nuclear division 1 homolog) pathogenic variants are known to cause combined oxidative phosphorylation deficiency (COXPD11), a severe multisystem disorder. In one patient, a homozygous RMND1 pathogenic variant, with an established role in COXPD11, was associated with a Perrault-like syndrome. We performed a thorough clinical investigation and applied a targeted multigene hearing loss panel to reveal the cause of hearing loss, ovarian dysfunction (two cardinal features of Perrault syndrome) and chronic kidney disease in two adult female siblings. Two compound heterozygous missense variants, c.583G>A (p.Gly195Arg) and c.818A>C (p.Tyr273Ser), not previously associated with disease, were identified in RMND1 in both patients, and their segregation with disease was confirmed in family members. The patients have no neurological or intellectual impairment, and nephrological evaluation predicts a benign course of kidney disease. Our study presents the mildest, so far reported, RMND1-related phenotype and delivers the first independent confirmation that RMND1 is causally involved in the development of Perrault syndrome with renal involvement. This highlights the importance of including RMND1 to the list of Perrault syndrome causative factors and provides new insight into the clinical manifestation of RMND1 deficiency.

Abstract
INTRODUCTION Sweet syndrome (SS) is an idiopathic autoimmune disease which has been associated with various extracutaneous manifestations. Otologic symptoms secondary to SS are characterized by bilateral, progressive, sensorineural hearing loss, which requires auditory rehabilitation with, for example, cochlear implantation. PATIENT CONCERNS A 43-year-old woman complaining of bilateral sudden hearing loss visited the Emergency Department of our University. Abrupt onset of fever peaking up to 40°C and vomiting accompanied the hearing loss and other associated symptoms were: tinnitus that sounded like a machine humming, mild dizziness, a painful rash (on the right upper eyelid, chest, back, forearms, and lower extremities), arthralgia in both the hip and knee joints, and vision loss in the right eye. The patient had no history of autoimmune diseases or surgery. DIAGNOSIS Pure tone audiometry and biopsy on the skin lesion were performed. SS with bilateral sudden sensorineural hearing loss was confirmed. INTERVENTIONS The patient was treated with intravenous prednisolone and topical steroids. OUTCOMES After a week of treatment, skin lesions had improved. And 3 months after treatment, the hearing test showed full recovery. CONCLUSION This case emphasizes the point that early diagnosis and timely treatment are essential for hearing recovery in patients with SS who have otologic symptoms.

Abstract
BACKGROUND The aim of this study was to compare the risk of developing sudden sensorineural hearing loss (SSHL) in patients with hypopharyngeal cancer with that in patients with nasopharyngeal carcinoma (NPC). METHODS A population-based, retrospective cohort study was performed using the Taiwan National Health Research Database databank. Patients selected for this study were diagnosed with hypopharyngeal cancer or NPC and treated with radiotherapy in the period from 2001 to 2004. Routine follow-up was conducted for 8 years (2004-2012), and the incidence of SSHL was calculated at the final follow-up. RESULTS There was no significant difference in the risk of developing SSHL between the hypopharyngeal cancer group and its control group (p = 1.000). In hypopharyngeal cancer and NPC groups, the rates of SSHL were 0.12% and 1.00%, respectively (p < 0.001). The cumulative hazard of SSHL during the follow-up period was significantly higher in the NPC group than in the control group (p < 0.001). CONCLUSION Radiotherapy in patients with hypopharyngeal cancer did not increase the risk of developing SSHL, but postirradiation NPC was significantly associated with an increased incidence of SSHL.

Abstract
Fitting amplification to a patient with Ménière's disease (MD) can present several challenges to the dispensing audiologist. These challenges include the presence of fluctuating hearing loss, a rising audiometric configuration, unilateral or asymmetrical hearing loss, reduced dynamic range, and reduced word-recognition scores. The presence of any one of these characteristics could create obstacles for a successful hearing aid fit. The presence of most if not all of these characteristics in a single patient can readily challenge the skills of even the most experienced dispensing audiologist. In addition to the audiometric challenges, this patient population has the added psychological problems associated with feeling ill due to the nausea secondary to vertiginous attacks and the anxiety associated with the unpredictable nature of the course of these attacks. This paper summarizes numerous strategies and technologies that could be implemented by the audiologist to address these unique challenges and provide a greater opportunity for a successful hearing aid fit. These suggestions include (1) advantages offered by digital signal processing; (2) using directional microphones and assistive listening devices to improve speech recognition in noise; (3) using wireless hearing aids as well as the bone anchored hearing aid; (4) counseling patients on the realistic expectations from amplification in noisy listening situations and for those with poor speech recognition; (5) using multiple programs for patients with fluctuating hearing loss; and (6) offering suggestions on programming the frequency-gain/output response for a rising configuration.

Abstract
This study investigated the characteristics of hearing loss in children with ventriculoperitoneal (VP) shunted hydrocephalus. Twelve hydrocephalic children with patent VP shunts participated. The etiology of the hydrocephalus was either intraventricular hemorrhage or spina bifida. Audiometric examination included pure-tone air conduction thresholds, tympanometry, contralateral and ipsilateral acoustic reflex thresholds (ARTs), and distortion product otoacoustic emissions (DPOAEs). A unilateral, high-frequency, cochlear hearing loss was found in the ear ipsilateral to the shunt placement in 10 (83%) of the 12 shunt-treated hydrocephalic children. No hearing loss was observed in the ear contralateral to shunt placement. Based on the pure-tone audiometric findings, coupled with the decrease in DPOAE amplitude in the shunt ear, the hearing loss appears to be cochlear in nature. We suggest that cochlear hydrodynamics are disrupted as the result of reduced perilymph pressure, a consequence of cerebrospinal fluid (CSF) reduction due to the combined effects of a patent shunt and a patent cochlear aqueduct. In addition, a concomitant brain stem involvement is evidenced in the ART pattern, possibly produced by the patent shunt draining the CSF from the subdural space, resulting in cranial base hypoplasia.

Abstract
BACKGROUND Congenital cytomegalovirus (CMV) infection is the most common non-genetic cause of sensorineural hearing loss (SHNL) in children. Only about 10% to 15% of children with congenital CMV are symptomatic, and most are not diagnosed at birth. About 7% to 15% of clinically asymptomatic patients may develop later complications, including SNHL, which is the most common sequela in clinically asymptomatic patients. In this study, hearing status was investigated in children with confirmed CMV infection and neonatal hearing screening (NHS) histories were reviewed to explore hearing loss caused by CMV. METHODS The medical records of 58 children who were diagnosed with confirmed CMV infection were reviewed for clinical symptoms and signs of CMV infection. Hearing status was evaluated with age-appropriate audiological test batteries. RESULTS A total of 58 children (M:F = 32:26 patients; age at study: mean, 5.62 years, range, 1-10 years) were diagnosed serologically with CMV infection (14 patients, 21.1%), or diagnosed via PCR of serum (5, 7.9%) and/or PCR from urine (19, 26.8%). Hearing loss was confirmed in 11 children (19.0%), being bilateral in 6 (54.5%), and unilateral in 5 (45.5%). Note that 7 of 17 ears with hearing loss passed NHS and were diagnosed only after re-evaluation when CMV infection was identified. CONCLUSION Hearing loss is a serious complication of CMV infection in children. Our results highlight the importance of timely audiological evaluation in children with clinically symptomatic CMV infection even if they pass NHS.

Abstract
OBJECTIVE The aim of this study was to report a case of cochlear implantation (CI) for a patient with an otic capsule-sparing traumatic brain injury (TBI) and to review the relevant literature. METHODS A patient with history of TBI received a CI for bilateral profound hearing loss. A systematic review of the literature was performed to identify and compare similar cases. RESULTS A 36-year-old male with a history of hearing loss from right acute labyrinthitis was referred for bilateral profound sensorineural hearing loss (SNHL) after a fall with associated injury to the central auditory nervous system (CANS) including the brainstem. On the right, behavioral acoustic threshold measurements were in the profound range with absent OAEs. On the left, testing revealed no measurable behavioral acoustic thresholds and variable physiologic measures. A right unilateral cochlear implant was performed with most recent follow-up demonstrating speech awareness thresholds of 25 dB HL with excellent detection of all 6 Ling sounds. However, the patient also continues to suffer from other neurologic sequelae related to his TBI, which challenge his ability to demonstrate objective and subjective benefit. A systematic review of the literature demonstrates variable outcomes for patients with TBI and SNHL. CONCLUSIONS Patients with profound SNHL and TBI present a distinct rehabilitative challenge for clinicians. CI may provide meaningful benefit in this population, though care should be taken in patient selection and counseling.

Abstract
Primary cilia are sensory organelles crucial for cell signaling during development and organ homeostasis. Cilia arise from centrosomes and their formation and function is governed by numerous factors. Through our studies on Townes-Brocks Syndrome (TBS), a rare disease linked to abnormal cilia formation in human fibroblasts, we uncovered the leucine-zipper protein LUZP1 as an interactor of truncated SALL1, a dominantly-acting protein causing the disease. Using TurboID proximity labeling and pulldowns, we show that LUZP1 associates with factors linked to centrosome and actin filaments. Here, we show that LUZP1 is a cilia regulator. It localizes around the centrioles and to actin cytoskeleton. Loss of LUZP1 reduces F-actin levels, facilitates ciliogenesis and alters Sonic Hedgehog signaling, pointing to a key role in cytoskeleton-cilia interdependency. Truncated SALL1 increases the ubiquitin proteasome-mediated degradation of LUZP1. Together with other factors, alterations in LUZP1 may be contributing to TBS etiology.

Abstract
BACKGROUND AND PURPOSE Bacterial meningitis most commonly affects young children and can result in critical adverse outcomes, including sensorineural hearing loss (SNHL). The purpose of this study is to determine the diagnostic accuracy of MR imaging for predicting the development of SNHL among infants with bacterial meningitis. MATERIALS AND METHODS A retrospective review was performed among infants (age <365 days) with bacterial meningitis (n = 115). Independent and consensus blinded review of brain MRIs (n = 239) performed less than 90 days from presentation were conducted. Abnormal appearance of the inner ear was defined as enhancement on postcontrast T1-weighted (T1-weighted+C) sequence and FLAIR hyperintensity. The consensus MR imaging appearance of the inner ear on FLAIR, T1-weighted+C, and combined evaluation was compared with criterion standard audiometric testing to determine the sensitivity and specificity of MR imaging for detecting SNHL. RESULTS The mean age at diagnosis of bacterial meningitis was 50.6 days (range, 0-338 days) and 24.3% had SNHL. Sensitivity and specificity was 0.61/0.96, 0.50/0.94, and 0.61/0.94 for T1-weighted+C, FLAIR hyperintensity, and combined evaluation, respectively, for prediction of SNHL. There was excellent interobserver agreement for both the T1-weighted+C and FLAIR sequences and combined evaluation for presence of abnormal enhancement and hyperintense signal, respectively. Factors associated with abnormal MR imaging findings on T1-weighted+C and/or FLAIR in patients with SNHL included low CSF glucose (P = .04, .02) and high CSF protein (P = .04, .03). CONCLUSIONS Abnormal enhancement and/or FLAIR hyperintensity of the inner ear demonstrate high specificity and average sensitivity for prediction of SNHL among infants with bacterial meningitis.

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
OBJECTIVES To analyze the clinical characteristics of cochlear fistulas (CFs) and propose a new fistula classification system with regard to the cochlea. MATERIALS AND METHODS A retrospective chart review was conducted between January 2008 and December 2015 to identify patients who had undergone surgery for cholesteatoma with an associated CF. The following data were collected: preoperative symptoms, findings of temporal bone computed tomography (TBCT), fistula stage, cholesteatoma classification, surgical technique, and pre- and postoperative pure-tone audiometry. RESULTS We analyzed a total of 159 patients, out of which 9 (5.7%) were diagnosed with a CF. The average duration of the chronic otitis media was 19.8 years. Cholesteatomas that induced CF rarely existed in the nonaggressive state; recurrent otorrhea was observed in all but one of our subjects. All the patients with CF had a distinct origin of cholesteatoma that developed from the retraction of posterior pars tensa; further, 88.9% cholesteatomas extended to and filled the sinus tympani. Preoperative audiometry revealed total hearing loss in 4 (44.4%) patients. Further, five patients with residual hearing before surgery had stage I fistulas, and the bone conduction thresholds remained stable after surgery. CONCLUSION Cochlear fistulas were often detected in patients with (1) a history of chronic otitis media (exceeding 10 years), (2) frequently recurring otorrhea, and (3) pars tensa cholesteatomas that extended to the posterior mesotympanum and filled the sinus tympani. Such patients can suffer from potentially severe and irreparable sensorineural hearing loss.

Abstract
BACKGROUND Many conditions, among them vestibular schwannoma and middle ear cholesteatoma with lateral semicircular canal destruction, may be associated with asymmetrical sensorineural hearing loss (SNHL) and vertigo. However, the probability that these two distinct disease entities causing the same symptoms occur in a single patient is very low, approximately 1 per 28 billion per 1 year. METHODS We present the case of a 40-year-old male admitted to our clinic because of chronic middle ear inflammation with concomitant tinnitus vertigo, and deafness in the right ear. The patient was diagnosed with lateral semicircular canal fistula caused by middle-ear cholesteatoma and concomitant vestibular schwannoma. Canal wall-down surgery was carried out to remove the cholesteatoma, followed by gamma knife radiosurgery for the vestibular schwannoma. RESULTS Vertigo and tinnitus resolved within 3 days after the ear surgery, and gamma knife treatment resulted in the complete involution of the vestibular schwannoma. The patient presented with completely dry middle-ear cavity and no recurrence of the cholesteatoma was observed during a 3-year follow-up. CONCLUSION As the hereby reported condition is very rare, the results cannot be compared with any similar report published previously. Nevertheless, based on the outcome, the treatment strategy seems to be both reasonable and effective.

Abstract
BACKGROUND Aquaporin 4 (AQP4)- and myelin oligodendrocyte glycoprotein (MOG)-associated neuromyelitis optica spectrum disorders (NMOSD) are thought to primarily affect the central nervous system (CNS). However, emerging evidence suggests that there are extra-CNS manifestations of NMOSD, including myopathies, gastrointestinal dysfunction, renal involvement and adverse pregnancy outcomes.1 METHODS: Three patients who reported hearing loss during a NMOSD relapse were identified through a retrospective case review. RESULTS In this article, we discuss two AQP4-IgG positive NMOSD cases, each presenting with conductive and sensorineural hearing loss, and a case of MOG-IgG-associated NMOSD presenting with sensorineural hearing loss. CONCLUSION Hearing loss may be present as a relapse in patients with NMOSD. Early recognition and timely treatment are essential to prevent irreversible hearing loss.

Abstract
BACKGROUND Due to high prevalence of vitamin D deficiency and the possible association with Sudden Sensory-Neural Hearing Loss (SSNHL) finding the main causes and appropriate treatments are highly essential. This study aimed to investigate vitamin D levels in patients suffering SSNHL and its effect on response to treatment. MATERIALS AND METHODS This cross-sectional study was performed on two groups of case (34 SSNHL patients) and control (34 healthy subjects without risk of hearing loss). All patient information such as age, sex, audiogram illustration of hearing frequency and the level of vitamin D were recorded at baseline. Patients with SSNHL received routine treatments such as 10 days of 1 mg/kg/day steroid and the response or lack of complete response to treatment was recorded and analyzed according to the audiometry. RESULTS Vitamin D level in SSNHL group with a mean of 19.28 ± 9.56 ng/ml was significantly less than the control group (25.71 ± 11.21 ng/ml; P value < 0.001). After treatment, 76.5% were completely recovered and 23.5% did not recover completely. Factors such as age, sex and level of initial hearing loss did not have a significant effect on the response to treatment, but the level of vitamin D in these patients had a significant relationship with the response to treatment (P value = 0.004); so that all patients with sufficient vitamin D level had completely recovered, versus 87.5% of patients with vitamin D deficiency and 12.5% of insufficient vitamin D had no response to treatment. CONCLUSION According to the results of the present study, the prevalence of vitamin D deficiency in patients with SSNHL was more than healthy people. SSNHL patients with deficient vitamin D had the highest percentage of no response to treatment.

Abstract
Superficial siderosis (SS) is a slowly progressive neurodegenerative disorder caused by persistent or intermittent bleeding into the subarachnoid space. It leads to characteristic clinical and radiographic findings. Dural pathology is believed to be the most common identifiable etiology of SS. It has been suggested that dural tear may be the common pathology of both SS and intracranial hypotension syndrome. We present a patient with SS caused by posttraumatic duropathy that was associated with cerebrospinal fluid (CSF) hypotension headache. Patient was treated surgically with stabilization of neurological deficit and orthostatic headache improvement. It supports the speculated link between both entities and may confirm surgery being a reasonable approach in patients with SS.

Abstract
Background: Little evidence is available about the risk of sudden sensorineural hearing loss (SSNHL) in patients with thyroid diseases. We assessed whether a diagnosis of thyroid disease, particularly hyperthyroidism or hypothyroidism, is associated with SSNHL risk in an Asian population. Material and Methods: This case-control study was conducted with population-based data from Taiwan’s National Health Insurance Research Database from January 2000 to December 2013. The case group comprised 3331 adult patients with newly diagnosed SSNHL, and four controls without SSNHL for each case matched by sex, age, monthly income, and urbanization level of residence. Underlying Thyroid diseases were retrospectively evaluated in the case and control groups. Multivariate logistic regression analyses were used to explore relations between thyroid diseases and SSNHL. Results: Of the 3331 cases, 5.7% had preexisting thyroid diseases, whereas only 4.0% of the 13,324 controls had the same condition. After adjustment for sex, age, monthly income, urbanization level of residence, history of hypertension, diabetes mellitus, chronic otitis media, and hyperlipidemia, associations were identified between a history of either hypothyroidism (adjusted odds ratio [AOR], 1.54; 95% CI, 1.02–2.32; p = 0.042) or hyperthyroidism (AOR, 1.41; 95% CI, 1.07–1.85; p = 0.015) and an elevated risk of SSNHL. In subgroup analysis, the correlation between hypothyroidism and increased SSNHL risk remained significant only for patients aged over 50 years (AOR, 1.61; 95% CI, 1.01–2.57; p = 0.045), and that between hyperthyroidism and SSNHL was significant only for female patients (AOR, 1.48; 95% CI, 1.09–2.01; p = 0.012). Treatment for hypothyroidism and hyperthyroidism did not alter the association in subgroup analyses. Conclusion: Preexisting hypothyroidism and hyperthyroidism appear associated with SSNHL susceptibility in Taiwan. Physicians should be wary of this elevated risk of SSNHL among patients with previously diagnosed thyroid dysfunction, especially women and patients aged more than 50 years.

Abstract
Sudden sensorineural hearing loss (SSNHL) presents as an abrupt onset of hearing loss; 88% of these presentations are idiopathic (ISSHL). Many mechanisms of injury and etiopathologies have been postulated, but they share a common result - hypoxia of the organ of Corti leading to hair cell-cilia fusion, synaptic, dendritic swelling and sustained depolarization. Of all of the various treatments tried, only corticosteroids and hyperbaric oxygen (HBO2) therapy have shown benefit in randomized controlled trials (RCTs). This paper reviews the pathophysiology of SSNHL, the variety of treatments studied, and the best evidence (both retrospective case controlled and prospective randomized controlled studies) for the use of HBO2 and corticosteroids. The best results are obtained when these two treatments are combined and initiated within 14 days of symptom onset. HBO2 is given at 2-2.5 ATA for 90 minutes for 10-20 sessions. Steroids should be dosed at 1mg/kg/day and slowly tapered over two to three weeks. If a patient is not a good candidate for or refuses systemic steroids, good results have also been obtained using intratympanic (IT) steroids in combination with HBO2. Patients should be followed by and otolaryngologist before, during and following HBO2. For severe hearing loss treatment with HBO2 improves by 37.7 dB, 19.3dB for those with moderate loss and 15.6 dB improvement overall. These recoveries, on average, improve a patient's hearing from ranges requiring hearing aids and sign language, to levels at which normal or near-normal hearing is restored.

Abstract
OBJECTIVE To describe the progression of sensorineural hearing loss (SNHL) in the better- and poorer-hearing ears in children with asymptomatic congenital cytomegalovirus (CMV) infection with isolated SNHL. STUDY DESIGN Longitudinal prospective cohort study. SETTING Tertiary medical center. SUBJECTS AND METHODS We analyzed hearing thresholds of the better- and poorer-hearing ears of 16 CMV-infected patients with isolated congenital/early-onset or delayed-onset SNHL identified through hospital-based CMV screening of >30,000 newborns from 1982 to 1992. RESULTS By 12 months of age, 4 of 7 patients with congenital/early-onset SNHL developed worsening thresholds in the poorer-hearing ear, and 1 had an improvement in the better-hearing ear. By 18 years of age, all 7 patients had worsening thresholds in the poorer-hearing ear and 3 patients had worsening thresholds in the better-hearing ear. Hearing loss first worsened at a mean age of 2 and 6 years in the poorer- and better-hearing ears, respectively. Nine patients were diagnosed with delayed-onset SNHL (mean age of 9 years vs 12 years for the poorer- and better-hearing ears), 6 of whom had worsening thresholds in the poorer-hearing ear and 1 in both ears. CONCLUSION In most children with congenital CMV infection and isolated SNHL, the poorer-hearing ear worsened earlier and more precipitously than the better-hearing ear. This study suggests that monitoring individual hearing thresholds in both ears is important for appropriate interventions and future evaluation of efficacy of antiviral treatment.

Abstract
The TWNK (C10orf2) gene encodes Twinkle, an essential helicase for mtDNA replication. Homozygous mutations in TWNK can lead to mitochondrial DNA depletion syndrome 7 (MTDPS7) that usually manifests as Infantile onset spinocerebellar ataxia (IOSCA). Here, we report a 15-year-old Iranian boy with three main symptoms; ataxia, sensorineural hearing loss and optic nerves atrophy which were accompanied by other symptoms including flexion contracture, dysarthric speech, nystagmus, dystonia and borderline intellectual disability. Whole exome sequencing (WES) revealed a homozygous mutation in his TWNK gene. The mutation was a transversion which replaced a C with A (NM_021830.4 (TWNK):c.874C>A). This nucleotide substitution results in replacing a Threonine with Proline in codon 292 of Twinkle protein (p.Pro292Thr). In silico analyses showed that this amino acid change in Twinkle could be deleterious and disease-causing; therefore, we attribute the symptoms of our patient to this mutation. Our study extended the homozygous mutation spectrum of the TWNK gene that leads to IOSCA.

Abstract
PURPOSE Stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (fSRT) are noninvasive therapies for vestibular schwannomas providing excellent tumor control. However, delayed hearing loss after radiation therapy remains an issue. One potential target to for improving hearing rates is limiting radiation exposure to the cochlea. METHODS We retrospectively reviewed 100 patients undergoing either SRS with 12 Gy (n = 43) or fSRT with 50 Gy over 28 fractions (n = 57) for vestibular schwannoma. Univariate and multivariate analysis were carried out to identify predictors of hearing loss as measured by the Gardner Robertson scale after radiation therapy. RESULTS Deterioration of hearing occurred in 30% of patients with SRS and 26% with fSRT. The overall long term (> 2 year) progression rates were 20% for SRS and 16% for fSRT. Patients with a decrease in their Gardner Robertson hearing score and those that loss serviceable hearing had significantly higher average minimal doses to the cochlea in both SRS and fSRT cohorts. ROC analysis showed that a cut off of 5 Gy and 35 Gy, for SRS and fSRT respectively, predicted hearing loss with high sensitivity/specificity. CONCLUSION Our data suggests the minimal dose of radiation that the cochlear volume is exposed to is a predictor of delayed hearing loss after either SRS or fSRT. A threshold of 5 Gy/35 Gy may lead to improved hearing preservation after radiotherapy. Further prospective multi center studies can further elucidate this mechanism.

Abstract
The purpose of the current study was to evaluate the incidence of glaucoma in patients diagnosed with sensorineural hearing loss (SNHL) via the application of the National Health Insurance Research Database in Taiwan. A retrospective cohort study was conducted. Patients with a diagnosis of SNHL were enrolled in the study group after an exclusion procedure and a propensity score matched group without SNHL was served as the control group with a 1:2 ratio. The main outcome was regarded as the emergence of glaucoma diagnostic codes. Cox proportional hazard regression was applied to analyze the incidence and adjusted hazard ratio (aHR) of glaucoma in the multivariate model. A total of 15,686 patients diagnosed with SNHL were enrolled in the study group while another 31,372 non-SNHL individuals served as the control group. There were 444 glaucoma events in the study group and 647 glaucoma events in those non-SNHL individuals after the follow-up interval of 16 years. The study group demonstrated a significantly higher aHR compared to the control group after adjusting for multiple possible risk factors. In the subgroup analysis, both the normal tension glaucoma and angle closure glaucoma subgroups revealed a higher aHR in the study group. In conclusion, the patients with SNHL demonstrated a higher incidence of developing glaucoma. Moreover, the incidence was more prominent for patients diagnosed with normal tension glaucoma and angle closure glaucoma.

Abstract
Proteins anchored to the cell surface via glycosylphosphatidylinositol (GPI) play various key roles in the human body, particularly in development and neurogenesis. As such, many developmental disorders are caused by mutations in genes involved in the GPI biosynthesis and remodeling pathway. We describe ten unrelated families with bi-allelic mutations in PIGB, a gene that encodes phosphatidylinositol glycan class B, which transfers the third mannose to the GPI. Ten different PIGB variants were found in these individuals. Flow cytometric analysis of blood cells and fibroblasts from the affected individuals showed decreased cell surface presence of GPI-anchored proteins. Most of the affected individuals have global developmental and/or intellectual delay, all had seizures, two had polymicrogyria, and four had a peripheral neuropathy. Eight children passed away before four years old. Two of them had a clinical diagnosis of DOORS syndrome (deafness, onychodystrophy, osteodystrophy, mental retardation, and seizures), a condition that includes sensorineural deafness, shortened terminal phalanges with small finger and toenails, intellectual disability, and seizures; this condition overlaps with the severe phenotypes associated with inherited GPI deficiency. Most individuals tested showed elevated alkaline phosphatase, which is a characteristic of the inherited GPI deficiency but not DOORS syndrome. It is notable that two severely affected individuals showed 2-oxoglutaric aciduria, which can be seen in DOORS syndrome, suggesting that severe cases of inherited GPI deficiency and DOORS syndrome might share some molecular pathway disruptions.

Abstract
OBJECTIVE To illustrate a case of sensorineural hearing loss (SNHL) after immunotherapy based on T cell receptor (TCR) gene therapy using modified T cells recognizing melanoma antigen recognized by T cells 1 for disseminated melanoma. PATIENT We present a 59-year-old woman with profound subacute bilateral SNHL including unilateral deafness after immunotherapy based on TCR gene therapy using modified T cells recognizing melanoma antigen recognized by T cells 1 for disseminated melanoma. Ten days after treatment, the patient developed hearing loss of 57 dB hearing loss air conduction at pure-tone average 0.5-1-2-4 kHz in the right ear, and >100 dB hearing loss air conduction at pure-tone average 0.5-1-2-4 in the left ear. The right ear recovered partially, while the left ear remained deaf, despite oral prednisolone (1.0 mg/kg) and salvage treatment with three transtympanic injections of 0.5 ml dexamethasone (4.0 mg/ml). CONCLUSION Based on our presented case and a vast amount of literature there is circumstantial evidence that TCR gene therapy for melanoma targets the perivascular macrophage-like melanocytes in the stria vascularis, resulting in SNHL. We suggest that SNHL after TCR gene therapy may be caused by a disruption of the blood-labyrinth-barrier and the endolymphatic potential and/or a sterile inflammation of the stria vascularis. In severe cases like our subject, we posit that endolymphatic hydrops or hair cell loss may cause irreversible and asymmetrical deafness. Steroid prophylaxis via transtympanic application is debatable.
