Abstract
PURPOSE Assess practice patterns amongst pediatric otolaryngologist for the management of children with SSNHL. MATERIALS AND METHODS A cross-sectional online survey of members of the American Society of Pediatric Otolaryngology (ASPO) was performed; 135 responded. Patterns in treatment modalities, ancillary tests, and timing of treatment and follow-up were evaluated. These patterns were compared between respondents with different characteristics (number of years in practice, clinic location, and number of pediatric SSNHL cases within the last year) using ordered logistic regression, Kruskal-Wallis, Wilcoxon rank-sum, and Fisher's exact tests. RESULTS Mean time from onset of hearing loss to presentation to a pediatric otolaryngologist was 10 days (range 1-60 days). The most cited reasons for delay in care were 'patient not seeking any healthcare evaluation' (65 %) and 'lack of access to obtain an audiogram' (54 %). The most ordered blood work was complete blood count (14 %) and herpes simplex testing (15 %). Complete blood count was ordered more frequently by physicians in practice for >10 years compared with those in practice 1-10 years, P = 0.03. Most respondents reported treating with systemic steroids (86/92, 93 %), including intratympanic steroids (32/92, 35 %). Treatment with systemic steroids was more common in academic compared with private practice, P = 0.03. Antivirals were the most common additional agent prescribed (14/89, 16 %). Most patients were seen in follow-up 1-4 weeks after diagnosis (63/85, 74 %). CONCLUSIONS Most pediatric otolaryngologists treat SSNHL with systemic steroids. The remainder of the diagnostic and management paradigm varies significantly, highlighting the need to systematically define which treatment optimizes outcomes in this population.

Association of Genetic Diagnoses for Childhood-Onset Hearing Loss With Cochlear Implant Outcomes. JAMA Otolaryngol Head Neck Surg 2023; 149:212-222. [PMID: 36633841 PMCID: PMC9857764 DOI: 10.1001/jamaoto.2022.4463] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Accepted: 11/10/2022] [Indexed: 01/13/2023]
Abstract
Importance In the US, most childhood-onset bilateral sensorineural hearing loss is genetic, with more than 120 genes and thousands of different alleles known. Primary treatments are hearing aids and cochlear implants. Genetic diagnosis can inform progression of hearing loss, indicate potential syndromic features, and suggest best timing for individualized treatment. Objective To identify the genetic causes of childhood-onset hearing loss and characterize severity, progression, and cochlear implant success associated with genotype in a single large clinical cohort. Design, Setting, and Participants This cross-sectional analysis (genomics) and retrospective cohort analysis (audiological measures) were conducted from 2019 to 2022 at the otolaryngology and audiology clinics of Seattle Children's Hospital and the University of Washington and included 449 children from 406 families with bilateral sensorineural hearing loss with an onset younger than 18 years. Data were analyzed between January and June 2022. Main Outcomes and Measures Genetic diagnoses based on genomic sequencing and structural variant analysis of the DNA of participants; severity and progression of hearing loss as measured by audiologic testing; and cochlear implant success as measured by pediatric and adult speech perception tests. Hearing thresholds and speech perception scores were evaluated with respect to age at implant, months since implant, and genotype using a multivariate analysis of variance and covariance. Results Of 406 participants, 208 (51%) were female, 17 (4%) were African/African American, 32 (8%) were East Asian, 219 (54%) were European, 53 (13%) were Latino/Admixed American, and 16 (4%) were South Asian. Genomic analysis yielded genetic diagnoses for 210 of 406 families (52%), including 55 of 82 multiplex families (67%) and 155 of 324 singleton families (48%). Rates of genetic diagnosis were similar for children of all ancestries. Causal variants occurred in 43 different genes, with each child (with 1 exception) having causative variant(s) in only 1 gene. Hearing loss severity, affected frequencies, and progression varied by gene and, for some genes, by genotype within gene. For children with causative mutations in MYO6, OTOA, SLC26A4, TMPRSS3, or severe loss-of-function variants in GJB2, hearing loss was progressive, with losses of more than 10 dB per decade. For all children with cochlear implants, outcomes of adult speech perception tests were greater than preimplanted levels. Yet the degree of success varied substantially by genotype. Adjusting for age at implant and interval since implant, speech perception was highest for children with hearing loss due to MITF or TMPRSS3. Conclusions and Relevance The results of this cross-sectional study suggest that genetic diagnosis is now sufficiently advanced to enable its integration into precision medical care for childhood-onset hearing loss.

Abstract
Children with bilateral sensorineural hearing loss (SNHL) should undergo a comprehensive medical evaluation to determine the underlying etiology and help guide treatment and counseling. In this article, we review the indications and rationale for medical evaluation of pediatric bilateral SNHL, including history and physical examination, imaging, genetic testing, specialist referrals, cytomegalovirus (CMV) testing, and other laboratory tests. Workup begins with a history and physical examination, which can provide clues to the etiology of SNHL, particularly with syndromic causes. If SNHL is diagnosed within the first 3 weeks of life, CMV testing should be performed to identify patients that may benefit from antiviral treatment. If SNHL is diagnosed after 3 weeks, testing can be done using dried blood spots samples, if testing capability is available. Genetic testing is oftentimes successful in identifying causes of hearing loss as a result of recent technological advances in testing and an ever-increasing number of identified genes and genetic mutations. Therefore, where available, genetic testing should be performed, ideally with next generation sequencing techniques. Ophthalmological evaluation must be done on all children with SNHL. Imaging (high-resolution computed tomography and/or magnetic resonance imaging) should be performed to assess for anatomic causes of hearing loss and to determine candidacy for cochlear implantation when indicated. Laboratory testing is indicated for certain etiologies, but should not be ordered indiscriminately since the yield overall is low.

Abstract
Sensorineural hearing impairment is the most frequent form of hearing impairment affecting 1-2 in 1000 newborns and another 1 in 1000 adolescents. More than 50% of congenital hearing impairment is of genetic origin and some forms of monogenic deafness are likely targets for future gene therapy. Good progress has been made in clinical phenotyping, genetic diagnostics, and counselling. Disease modelling, e.g. in transgenic mice, has helped elucidate disease mechanisms underlying genetic hearing impairment and informed clinical phenotyping in recent years. Clinical management of paediatric hearing impairment involves hearing aids, cochlear or brainstem implants, signal-to-noise improvement in educational settings, speech therapy, and sign language. Cochlear implants, for example, have much improved the situation of profoundly hearing impaired and deaf children. Nonetheless there remains a major unmet clinical need for improving hearing restoration. Preclinical studies promise that we will witness clinical trials on gene therapy and a next generation of cochlear implants during the coming decade. Moreover, progress in generating sensory hair cells and neurons from stem cells spurs disease modelling, drug screening, and regenerative approaches. This review briefly summarizes the pathophysiology of paediatric hearing impairment and provides an update on the current preclinical development of innovative approaches toward improved hearing restoration.

Abstract
Hearing loss is one of the most common concerns for presentation for a geneticist. Presentation prior to the age of one (congenital hearing loss), profound sensorineural hearing loss (SNHL), and bilateral hearing loss are sensitive and should raise concern for genetic causes of hearing loss and prompt referral for genetic testing. Genetic testing particularly in this instance offers the opportunity for anticipatory guidance including possible course of the hearing loss over time and also connection and evaluation for additional congenital anomalies that may be associated with an underlying syndrome vs. isolated genetic hearing loss.

Abstract
IMPORTANCE Hearing loss in children is common and by age 18 years, affects nearly 1 of every 5 children. Without hearing rehabilitation, hearing loss can cause detrimental effects on speech, language, developmental, educational, and cognitive outcomes in children. OBSERVATIONS Consequences of hearing loss in children include worse outcomes in speech, language, education, social functioning, cognitive abilities, and quality of life. Hearing loss can be congenital, delayed onset, or acquired with possible etiologies including congenital infections, genetic causes including syndromic and nonsyndromic etiologies, and trauma, among others. Evaluation of hearing loss must be based on suspected diagnosis, type, laterality and degree of hearing loss, age of onset, and additional variables such as exposure to cranial irradiation. Hearing rehabilitation for children with hearing loss may include use of hearing aids, cochlear implants, bone anchored devices, or use of assistive devices such as frequency modulating systems. CONCLUSIONS AND RELEVANCE Hearing loss in children is common, and there has been substantial progress in diagnosis and management of these cases. Early identification of hearing loss and understanding its etiology can assist with prognosis and counseling of families. In addition, awareness of treatment strategies including the many hearing device options, cochlear implant, and assistive devices can help direct management of the patient to optimize outcomes.

Abstract
Wnt/β-Catenin signaling is required for the development and differentiation of cochlear hair cells. Total of 80 natural compounds derived from the FDA-approved Drug Library of Selleck were screened by T-cell factor Reporter Plasmid (TOP)-Flash assay to identify the activation of Wnt/β-Catenin signaling. The mouse cochlear hair cells (HEI-OC1) were treated with cisplatin with or without Guaiacin, and the relative expression of β-Catenin and TRIM33 were detected by qRT-PCR and Western blots. The viability of HEI-OC1 was assayed by MTT method, and mouse cochlear cultures were utilized to detect the Ex vivo survival of cochlear hair cells. Guaiacin was testified to have the most vigorous ability to promote Wnt/β-Catenin signaling among 80 compounds detected, and it can also improve the β-Catenin signaling in mouse cochlear hair cells with up-regulated β-Catenin protein expression, unchanged β-Catenin mRNA expression, and down-regulated TRIM33 expression. Guaiacin increased the viability of HEI-OC1 cells cultured with or without cisplatin, and such a protective effect was also testified in mouse cochlear cultures. Our data indicate that Guaiacin could increase Wnt/β-Catenin signaling by regulating TRIM33/β-Catenin axis, which contributes to the improved survival of cochlear hair cells.
