Abstract
Background This paper describes the development of low-cost, effective, non-invasive machine learning-based prediction models for Down Syndrome in the first two trimesters of pregnancy in Vietnam. These models are adaptable to different situations with limited screening capacities at community-based healthcare facilities. Method Ultrasound and biochemical testing alone and in combination, from both trimesters were employed to build prediction models based on k-Nearest Neighbor, Support Vector Machine, Random Forest, and Extreme Gradient Boosting algorithms. Results A total of 7,076 pregnant women from a single site in Northern Vietnam were included, and 1,035 had a fetus with Down Syndrome. Combined ultrasound and biochemical testing were required to achieve the highest accuracy in trimester 2, while models based only on biochemical testing performed as well as models based on combined testing during trimester 1. In trimester 1, Extreme Gradient Boosting produced the best model with 94% accuracy and 88% AUC, while Support Vector Machine produced the best model in trimester 2 with 89% accuracy and 84% AUC. Conclusions This study explored a range of machine learning models under different testing scenarios. Findings point to the potential feasibility of national screening, especially in settings without enough equipment and specialists, after additional model validation and fine tuning is performed.

Abstract
OBJECTIVES Individuals with Down syndrome (DS) have a higher incidence of hearing loss (HL) compared with their peers without developmental disabilities. Little is known about the associations between HL and functional hearing for individuals with DS. This study investigated two aspects of auditory functions, "what" (understanding the content of sound) and "where" (localizing the source of sound), in young adults with DS. Speech reception thresholds in quiet and in the presence of interferers provided insight into speech recognition, that is, the "what" aspect of auditory maturation. Insights into "where" aspect of auditory maturation were gained from evaluating speech reception thresholds in colocated versus separated conditions (quantifying spatial release from masking) as well as right versus left discrimination and sound location identification. Auditory functions in the "where" domain develop during earlier stages of cognitive development in contrast with the later developing "what" functions. We hypothesized that young adults with DS would exhibit stronger "where" than "what" auditory functioning, albeit with the potential impact of HL. Considering the importance of auditory working memory and receptive vocabulary for speech recognition, we hypothesized that better speech recognition in young adults with DS, in quiet and with speech interferers, would be associated with better auditory working memory ability and receptive vocabulary. DESIGN Nineteen young adults with DS (aged 19 to 24 years) participated in the study and completed assessments on pure-tone audiometry, right versus left discrimination, sound location identification, and speech recognition in quiet and with speech interferers that were colocated or spatially separated. Results were compared with published data from children and adults without DS and HL, tested using similar protocols and stimuli. Digit Span tests assessed auditory working memory. Receptive vocabulary was examined using the Peabody Picture Vocabulary Test Fifth Edition. RESULTS Seven participants (37%) had HL in at least 1 ear; 4 individuals had mild HL, and 3 had moderate HL or worse. Participants with mild or no HL had ≥75% correct at 5° separation on the discrimination task and sound localization root mean square errors (mean ± SD: 8.73° ± 2.63°) within the range of adults in the comparison group. Speech reception thresholds in young adults with DS were higher than all comparison groups. However, spatial release from masking did not differ between young adults with DS and comparison groups. Better (lower) speech reception thresholds were associated with better hearing and better auditory working memory ability. Receptive vocabulary did not predict speech recognition. CONCLUSIONS In the absence of HL, young adults with DS exhibited higher accuracy during spatial hearing tasks as compared with speech recognition tasks. Thus, auditory processes associated with the "where" pathways appear to be a relative strength than those associated with "what" pathways in young adults with DS. Further, both HL and auditory working memory impairments contributed to difficulties in speech recognition in the presence of speech interferers. Future larger-sized samples are needed to replicate and extend our findings.

Abstract
We aim to determine the accessibility of gold-standard hearing assessments - audiogram or auditory brainstem response (ABR) - during the first 3 months of hearing health care for children with and without developmental disabilities. Electronic health records were examined from children (0-18 years) who received hearing health care at three hospitals. Children with developmental disabilities had a diagnosis of autism, cerebral palsy, Down syndrome, or intellectual disability. Assessments from the first 3 months were reviewed to determine if ≥ 1 audiogram or ABR threshold was recorded. To evaluate differences in assessment based on disability status, logistic regression models were built while accounting for age, race, ethnicity, sex, and site. Of the 131,783 children, 9.8% had developmental disabilities. Whereas 9.3% of children in the comparison group did not access a gold-standard assessment, this rate was 24.4% for children with developmental disabilities (relative risk (RR) = 3.79; p < 0.001). All subgroups were at higher risk relative to the comparison group (all p < 0.001): multiple diagnoses (RR = 13.24), intellectual disabilities (RR = 11.52), cerebral palsy (RR = 9.87), Down syndrome (RR = 6.14), and autism (RR = 2.88). Children with developmental disabilities are at high risk for suboptimal hearing evaluations that lack a gold-standard assessment. Failure to access a gold-standard assessment results in children being at risk for late or missed diagnosis for reduced hearing. Results highlight the need for (1) close monitoring of hearing by healthcare providers, and (2) advancements in testing methods and guidelines.

[PMID: 38964176 DOI: 10.1016/j.ijporl.2024.112018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 06/08/2024] [Accepted: 06/18/2024] [Indexed: 07/06/2024]
Abstract
BACKGROUND Down syndrome is associated with an increased risk for otitis media with effusion (OME), a childhood condition in which fluid accumulates in the middle ear, potentially leading to hearing loss. The American Academy of Pediatrics Down syndrome guidelines and the American Academy of Otolaryngology - Head and Neck Surgery OME guidelines recommend hearing testing to assess the hearing status of children with Down syndrome diagnosed with OME. METHODS Through an Institutional Review Board approved retrospective chart review at Children's Mercy, this project assessed how clinical factors affect the frequency in which children with Down syndrome receive hearing testing after diagnosis of OME. The study included data from all children with Down syndrome between 1 and 8 years old diagnosed with OME in the Down syndrome, general pediatrics, and otolaryngology clinics between 2018 and 2020. Demographics and clinical factors, including clinic setting, were collected. RESULTS Of the 124 patients identified, 91.1 % were diagnosed with OME in the otolaryngology clinic and 33.1 % received hearing testing. While most diagnoses occurred in the otolaryngology clinic, a higher proportion of hearing testing at the time of diagnosis occurred in the Down syndrome clinic. This could be explained by the fact that the Down syndrome clinic is a multidisciplinary clinic, where yearly visits include hearing screening. Bivariate analysis using chi-square or Fisher's tests showed that clinic setting had a significant association (p-value <0.001) with hearing testing. However, logistic regression depicted all clinical factors had an insignificant effect on hearing testing at 5 % significance. CONCLUSION While results indicate hearing testing is largely not performed to assess OME early in otolaryngology clinics, they may be used to assess intervention efficacy post-diagnosis. Results point to the importance of Down syndrome clinics in early diagnosis of hearing loss leading to timely referrals to otolaryngology clinics which diagnose and manage OME in children with Down syndrome.

Abstract
OBJECTIVE To characterize the management and outcomes of observation versus surgical intervention of tympanic membrane (TM) perforations in children with Down syndrome (DS). In addition, to estimate the prevalence of TM perforations in children with DS. METHODS Retrospective case review analysis of TM perforation rate in children with DS with history of tympanostomy tube (TT) insertion at a tertiary pediatric referral center. Patients were divided into observation or surgical intervention groups and then further evaluated for the type of intervention, the number of required procedures, and success rate of hearing improvement. Risk factors contributing to perforations were analyzed, including TT type, number of TT surgeries, and perforation size. RESULTS The TM perforation rate in children with DS with TT history was 7.0 %. Tympanoplasty was performed in 41.5 % of perforated ears with a success rate of 53.1 %. There was no statistical difference between the surgical intervention and observation groups regarding perforation characteristics or TT number and type, but the surgical intervention cohort was older. Hearing improvement based on postoperative pure tone average (PTA) threshold was noted in the successful surgical intervention group. CONCLUSION The rate of TM perforations in children with DS after TTs is comparable to the general population. Improved PTA thresholds were noted in the surgical success group influencing speech development. The overall lower success rate of tympanoplasty in patients with DS emphasizes the need to factor in the timing of surgical intervention based on the predicted age of Eustachian tube maturation.

Abstract
Developmental delay (DD), or intellectual disability (ID) is a very large group of early onset disorders that affects 1-2% of children worldwide, which have diverse genetic causes that should be identified. Genetic studies can elucidate the pathogenesis underlying DD/ID. In this study, whole-exome sequencing (WES) was performed on 225 Chinese DD/ID children (208 cases were sequenced as proband-parent trio) who were classified into seven phenotype subgroups. The phenotype and genomic data of patients with DD/ID were further retrospectively analyzed. There were 96/225 (42.67%; 95% confidence interval [CI] 36.15-49.18%) patients were found to have causative single nucleotide variants (SNVs) and small insertions/deletions (Indels) associated with DD/ID based on WES data. The diagnostic yields among the seven subgroups ranged from 31.25 to 71.43%. Three specific clinical features, hearing loss, visual loss, and facial dysmorphism, can significantly increase the diagnostic yield of WES in patients with DD/ID (P = 0.005, P = 0.005, and P = 0.039, respectively). Of note, hearing loss (odds ratio [OR] = 1.86%; 95% CI = 1.00-3.46, P = 0.046) or abnormal brainstem auditory evoked potential (BAEP) (OR = 1.91, 95% CI = 1.02-3.50, P = 0.042) was independently associated with causative genetic variants in DD/ID children. Our findings enrich the variation spectrums of SNVs/Indels associated with DD/ID, highlight the value genetic testing for DD/ID children, stress the importance of BAEP screen in DD/ID children, and help to facilitate early diagnose, clinical management and reproductive decisions, improve therapeutic response to medical treatment.

Abstract
BACKGROUND AND OBJECTIVES Additional needs refer to specific requirements or support for individuals with disabilities or syndromes. Intellectual ability is a crucial outcome determinant of a cochlear implant. The social quotient (SQ) is an indirect predictor of intellectual capacity and social skills. This study aimed to investigate the clinical significance of the SQ on children with additional needs who received cochlear implants. Subjects and. METHODS This study included 24 patients with diagnosed developmental delays and syndromes, who demonstrated SQ scores of <70. Preoperative social skills were evaluated using the SQ. All patients underwent cochlear implantation (CI) surgery before 7 years of age. Outcomes were evaluated using the Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) and Categories of Auditory Performance (CAP) scores. Data were collected through a retrospective chart review. RESULTS Children were categorized into three groups based on their SQ. There were no correlations between the preoperative SQ and IT-MAIS or CAP scores at 2 and 5 years of follow-up postoperatively. The CI outcomes of children with low SQ (<70) differed from those with normal development (SQ>70). In the low-SQ group, inner ear anomalies were observed in 10 (41.7%) patients. Although not statistically significant, these children exhibited a trend of lower average outcomes than children without inner ear anomalies. CONCLUSIONS CI outcomes in children with additional needs positively affected auditory performance. Postoperative auditory and language skills tended to improve slowly in children with additional needs and a lower SQ. Over time, development gradually became more comparable to the other groups of children. However, this improvement was less than that observed in children without additional needs. Our findings support CI for children with additional needs as part of long-term auditory rehabilitation following surgery.

Abstract
Approximately 40% of children with deafness have an additional developmental disorder or major medical problem, which may delay the age of diagnosis of hearing loss and/or require intervention by other professionals. This situation is referred to as "deafness with added disability" (AD+). The reason why the population of hearing-impaired children is more likely to have associated added disabilities is that the risk factors for hearing impairment overlap with those for many other disabilities. These factors can influence various aspects of development, including language acquisition. It is important to check that appropriate care is received, the effectiveness of hearing aids or implants, as well speech therapy intervention strategies, and family adherence to sessions and appointments. The challenge posed by AD+ is early detection, to allow early and appropriate intervention, and the need for fluid transdisciplinary collaboration between all professionals involved, together with the involvement of the family.

Abstract
OBJECTIVE Pediatric tracheostomy patients disproportionately experience hearing loss and are at risk for delayed identification due to their medical complexity. Nonetheless, protocols to monitor hearing in these children are lacking. This quality improvement (QI) initiative aimed to increase the rates of audiometric testing within 12 months of pediatric tracheostomy placement. METHODS A retrospective cohort study included children who underwent tracheostomy under 18 months of age between 2012 and 2020. Rates of audiometric assessments before and after QI project implementation (2015) were reported along with hearing loss characteristics. RESULTS A total of 253 children met inclusion. Before project initiation (2012-2014), 32% of children (28/87) obtained audiometric testing within 12 months after tracheostomy. During the first three years of implementation (2015-2017), 39% (38/97) were tested, while 55% (38/69) were tested during the subsequent three years (2018-2020) (P = .01). A passing newborn hearing screen was obtained for 70% of the 210 children with a recorded result, and 198 survived at least 12 months to receive audiometric testing at a median of 11.3 months (IQR: 6.2-22.8) after tracheostomy. Hearing loss was identified for 44% of children (N = 88), of which 42 children initially passed newborn hearing screen. A second assessment was obtained for 62% of children (123/198) at a median of 11.3 months (IQR: 4.5-17.5) after the initial test. In this group, 23% with a previously normal audiometric exam were found to have hearing loss (15/66). CONCLUSIONS QI initiatives designed to monitor hearing loss in children with a tracheostomy can result in improved rates of audiometric assessments. This population has disproportionately high rates of hearing loss, including delayed onset hearing loss making audiometric protocols valuable to address speech and language development delays.

Abstract
Background: Otitis media (OM) is defined as middle ear (ME) inflammation that is usually due to infection. Globally, OM is a leading cause of hearing loss and is the most frequently diagnosed disease in young children. For OM, pediatric patients with Down syndrome (DS) demonstrate higher incidence rates, greater severity, and poorer outcomes. However, to date, no studies have investigated the bacterial profiles of children with DS and OM. Method: We aimed to determine if there are differences in composition of bacterial profiles or the relative abundance of individual taxa within the ME and nasopharyngeal (NP) microbiotas of pediatric OM patients with DS (n = 11) compared with those without DS (n = 84). We sequenced the 16S rRNA genes and analyzed the sequence data for diversity indices and relative abundance of individual taxa. Results: Individuals with DS demonstrated increased biodiversity in their ME and NP microbiotas. In children with OM, DS was associated with increased biodiversity and higher relative abundance of specific taxa in the ME. Conclusion: Our findings suggest that dysbioses in the NP of DS children contributes to their increased susceptibility to OM compared with controls. These findings suggest that DS influences regulation of the mucosal microbiota and contributes to OM pathology.

Abstract
This review aimed to investigate the use of the Cambridge Neuropsychological Automated Testing Battery (CANTAB) for people at risk of cognitive impairment, especially those born with Down syndrome and those born preterm. Six databases were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, in addition to the bibliography index listed in the CANTAB site. Twenty four studies regarding Down syndrome and 17 regarding prematurity were reviewed and are here described. Both cognitive profiles were described, and their performance was compared on specific tasks and CANTAB tests. In this battery of tests, people with Down syndrome usually present impaired key cognitive domains, such as episodic memory and recognition memory. Results were presented considering general aspects described in the studies, specific findings such as dementia, the role of genetics, and cognitive profile, among other descriptions. Comparability between both populations in future studies is discussed.

Abstract
INTRODUCTION Individuals with intellectual disabilities (ID) often suffer from hearing loss, in most cases undiagnosed or inappropriately treated. The implementation of a programme of systematic hearing screening, diagnostics, therapy initiation or allocation and long-term monitoring within the living environments of individuals with ID (nurseries, schools, workshops, homes), therefore, seems beneficial. METHODS AND ANALYSIS The study aims to assess the effectiveness and costs of a low-threshold screening programme for individuals with ID. Within this programme 1050 individuals with ID of all ages will undergo hearing screening and an immediate reference diagnosis in their living environment (outreach cohort). The recruitment of participants in the outreach group will take place within 158 institutions, for example, schools, kindergartens and places of living or work. If an individual fails the screening assessment, subsequent full audiometric diagnostics will follow and, if hearing loss is confirmed, initiation of therapy or referral to and monitoring of such therapy. A control cohort of 141 participants will receive an invitation from their health insurance provider via their family for the same procedure but within a clinic (clinical cohort). A second screening measurement will be performed with both cohorts 1 year later and the previous therapy outcome will be checked. It is hypothesised that this programme leads to a relevant reduction in the number of untreated or inadequately treated cases of hearing loss and strengthens the communication skills of the newly or better-treated individuals. Secondary outcomes include the age-dependent prevalence of hearing loss in individuals with ID, the costs associated with this programme, cost of illness before-and-after enrolment and modelling of the programme's cost-effectiveness compared with regular care. ETHICS AND DISSEMINATION The study has been approved by the Institutional Ethics Review Board of the Medical Association of Westphalia-Lippe and the University of Münster (No. 2020-843 f-S). Participants or guardians will provide written informed consent. Findings will be disseminated through presentations, peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER DRKS00024804.

Abstract
Importance There are many features of Down syndrome that prompt referral to an otolaryngologist. As the lifetime prevalence and life expectancy of individuals with Down syndrome increase, it is increasingly likely that otolaryngologists will have the opportunity to care for patients with Down syndrome. Observations A confluence of characteristics common to Down syndrome may be associated with issues in the head and neck, from infancy through adulthood. Hearing concerns range from narrow ear canals and cerumen impactions to eustachian tube dysfunction, middle ear effusion, cochlear malformations, and conductive, sensorineural, and/or mixed hearing loss. Immune deficiency, hypertrophy of Waldeyer ring, and hypoplastic sinuses may complicate and develop into chronic rhinosinusitis. Speech delay, obstructive sleep apnea, dysphagia, and airway anomalies are also common among this patient population. Because these concerns may necessitate otolaryngologic surgery, it is vital for otolaryngologists to familiarize themselves with anesthetic concerns, including cervical spine instability, in patients with Down syndrome. Comorbid cardiac disease, hypothyroidism, and obesity may also affect these patients and otolaryngologic care. Conclusions and Relevance Individuals with Down syndrome may visit otolaryngology practices at all ages. Otolaryngologists that familiarize themselves with the head and neck manifestations that are common among patients with Down syndrome and know when to order screening tests will be able to provide comprehensive care.

Abstract
This is an update of the 2015 Guidelines developed by the Japan Otological Society and Oto-Rhino-Laryngeal Society of Japan defining otitis media with effusion (OME) in children (younger than 12 years old) and describing the disease rate, diagnosis, and method of examination. Recommended therapies that received consensus from the guideline committee were updated in consideration of current therapies used in Japan and based on available evidence. METHOD Regarding the treatment of OME in children, we developed Clinical Questions (CQs) and retrieved documents on each theme, including the definition, disease state, method of diagnosis, and medical treatment. In the previous guidelines, no retrieval expression was used to designate a period of time for literature retrieval. Conversely, a literature search of publications from March 2014 to May 2019 has been added to the JOS 2015 Guidelines. For publication of the CQs, we developed and assigned strengths to recommendations based on the collected evidence. RESULTS OME in children was classified into one group lacking the risk of developing chronic or intractable disease and another group at higher risk (e.g., children with Down syndrome, cleft palate), and recommendations for clinical management, including follow-up, is provided. Information regarding management of children with unilateral OME and intractable cases complicated by adhesive otitis media is also provided. CONCLUSION In clinical management of OME in children, the Japanese Clinical Practice Guidelines recommends management not only of complications of OME itself, such as effusion in the middle ear and pathologic changes in the tympanic membrane, but also pathologic changes in surrounding organs associated with infectious or inflammatory diseases.

Abstract
Hearing impairment is a cardinal feature of Down syndrome (DS), but its clinical manifestations have been attributed to multiple factors. Murine models could provide mechanistic insights on various causes of hearing loss in DS. To investigate mechanisms of hearing loss in DS in the absence of the cadherin 23 mutation, we backcrossed our DS mice, Dp(16)1Yey, onto normal-hearing CBA/J mice and evaluated their auditory function. Body weights of wild type (WT) and DS mice were similar at 3-months of age, but at 9-months, WT weighed 30% more than DS mice. Distortion product otoacoustic emissions (DPOAE), a test of sensory outer hair cell (OHC) function negatively impacted by conductive hearing loss, were reduced in amplitude and sensitivity across all frequencies in DS mice. The middle ear space in DS mice appeared normal with no evidence of infection. MicroCT structural imaging of DS temporal bones revealed a smaller tympanic membrane diameter, oval window, and middle ear space and localized thickening of the bony otic capsule, but no gross abnormalities of the middle ear ossicles. Histological analysis of the cochlear and vestibular sensory epithelium revealed a normal density of cochlear and vestibular hair cells; however, the cochlear basal membrane was approximately 0.6 mm shorter in DS than WT mice so that the total number of hair cells was greater in WT than DS mice. In DS mice, the early and late peaks in the auditory brainstem response (ABR), reflecting neural responses from the cochlear auditory nerve followed by subsequent neural centers in the brainstem, were reduced in amplitude and ABR thresholds were elevated to a similar degree across all frequencies, consistent with a conductive hearing impairment. The latency of the peaks in the ABR waveform were longer in DS than WT mice when compared at the same intensity; however, the latency delays disappeared when the data were compared at the same intensity above thresholds to compensate for the conductive hearing loss. Future studies using wideband tympanometry and absorbance together with detailed histological analysis of the middle ear could illuminate the nature of the conductive hearing impairment in DS mice.

Abstract
BACKGROUND Specific medical conditions are more prevalent in Down syndrome (DS) compared to the general population. Medical heterogeneity has also been hypothesized to contribute to variability in outcomes in DS. AIMS This project aimed to examine the association between medical conditions (i.e., gastrointestinal issues, hearing loss, vision problems, and congenital heart defects) and cognition, language, and behavior in children and adolescents with DS. METHODS AND PROCEDURES Participants were 73 children and adolescents with DS, ages 6-17 years (M = 12.67, SD = 3.16). Caregivers reported on participants' medical conditions, social behaviors, maladaptive behaviors, and executive function. Child cognitive abilities were also assessed. OUTCOMES AND RESULTS Of the 73 participants, 34.2% had gastrointestinal issues, 12.3% had uncorrected hearing loss, 26.0% had uncorrected vision problems, and 31.5% had congenital heart defects. Participants with gastrointestinal issues had significantly more challenges with social behaviors, maladaptive behaviors, and executive function compared to those without gastrointestinal issues. CONCLUSIONS AND IMPLICATIONS The associations identified between gastrointestinal issues and caregiver-reported behavioral characteristics in youth with DS contributes to our understanding of the interrelation between co-occurring medical conditions and child outcomes and has implications for approaches to care for individuals with DS.

Abstract
OBJECTIVE To assesses the current state of uncertainty concerning the management options used for otitis media with effusion (OME) in children with trisomy 21. REVIEW METHODS A systematic review of adhering to the PRISMA statement of studies evaluating the management of OME in trisomy 21 children prior to September 2021 was conducted. Studies were identified using the following medical databases: PubMed, Google Scholar, CINAHL, Scopus and Medline. Data extraction was performed by screening of titles and abstracts based on eligibility criteria, followed by full-article analysis of selected records. RESULTS Twenty articles were included in this review. Studies showed conflicting outcomes regarding the different interventions used for OME in children with trisomy 21. Of those evaluating pressure equalizing tubes (PET), some studies report pronounced complication rates and recommend using a conservative approach unless complications arise and/or hearing loss is severe. In contrast, other studies reported significantly reduced complication rates and improved hearing with earlier intervention and adaptations to PETs. Hearing aids may be provided after multiple failed PETs. CONCLUSION Clinical equipoise still persists regarding the best method to manage children with trisomy 21 who have OME. Although PETs exhibited the lowest complication rates and highest improvement rates, further prospective trials are warranted to assess the various treatment modalities and determine which of them would provide the best outcome while reducing complications as well as the age of treatment.

Abstract
OBJECTIVE Insertion of tympanostomy tubes is the most common ambulatory surgery performed on children in the United States. Tympanostomy tubes are most often inserted because of persistent middle ear fluid, frequent ear infections, or ear infections that persist after antibiotic therapy. All these conditions are encompassed by the term otitis media (middle ear inflammation). This guideline update provides evidence-based recommendations for patient selection and surgical indications for managing tympanostomy tubes in children. The guideline is intended for any clinician involved in managing children aged 6 months to 12 years with tympanostomy tubes or children being considered for tympanostomy tubes in any care setting as an intervention for otitis media of any type. The target audience includes specialists, primary care clinicians, and allied health professionals. PURPOSE The purpose of this clinical practice guideline update is to reassess and update recommendations in the prior guideline from 2013 and to provide clinicians with trustworthy, evidence-based recommendations on patient selection and surgical indications for managing tympanostomy tubes in children. In planning the content of the updated guideline, the guideline update group (GUG) affirmed and included all the original key action statements (KASs), based on external review and GUG assessment of the original recommendations. The guideline update was supplemented with new research evidence and expanded profiles that addressed quality improvement and implementation issues. The group also discussed and prioritized the need for new recommendations based on gaps in the initial guideline or new evidence that would warrant and support KASs. The GUG further sought to bring greater coherence to the guideline recommendations by displaying relationships in a new flowchart to facilitate clinical decision making. Last, knowledge gaps were identified to guide future research. METHODS In developing this update, the methods outlined in the American Academy of Otolaryngology-Head and Neck Surgery Foundation's "Clinical Practice Guideline Development Manual, Third Edition: A Quality-Driven Approach for Translating Evidence Into Action" were followed explicitly. The GUG was convened with representation from the disciplines of otolaryngology-head and neck surgery, otology, pediatrics, audiology, anesthesiology, family medicine, advanced practice nursing, speech-language pathology, and consumer advocacy. ACTION STATEMENTS The GUG made strong recommendations for the following KASs: (14) clinicians should prescribe topical antibiotic ear drops only, without oral antibiotics, for children with uncomplicated acute tympanostomy tube otorrhea; (16) the surgeon or designee should examine the ears of a child within 3 months of tympanostomy tube insertion AND should educate families regarding the need for routine, periodic follow-up to examine the ears until the tubes extrude.The GUG made recommendations for the following KASs: (1) clinicians should not perform tympanostomy tube insertion in children with a single episode of otitis media with effusion (OME) of less than 3 months' duration, from the date of onset (if known) or from the date of diagnosis (if onset is unknown); (2) clinicians should obtain a hearing evaluation if OME persists for 3 months or longer OR prior to surgery when a child becomes a candidate for tympanostomy tube insertion; (3) clinicians should offer bilateral tympanostomy tube insertion to children with bilateral OME for 3 months or longer AND documented hearing difficulties; (5) clinicians should reevaluate, at 3- to 6-month intervals, children with chronic OME who do not receive tympanostomy tubes, until the effusion is no longer present, significant hearing loss is detected, or structural abnormalities of the tympanic membrane or middle ear are suspected; (6) clinicians should not perform tympanostomy tube insertion in children with recurrent acute otitis media who do not have middle ear effusion in either ear at the time of assessment for tube candidacy; (7) clinicians should offer bilateral tympanostomy tube insertion in children with recurrent acute otitis media who have unilateral or bilateral middle ear effusion at the time of assessment for tube candidacy; (8) clinicians should determine if a child with recurrent acute otitis media or with OME of any duration is at increased risk for speech, language, or learning problems from otitis media because of baseline sensory, physical, cognitive, or behavioral factors; (10) the clinician should not place long-term tubes as initial surgery for children who meet criteria for tube insertion unless there is a specific reason based on an anticipated need for prolonged middle ear ventilation beyond that of a short-term tube; (12) in the perioperative period, clinicians should educate caregivers of children with tympanostomy tubes regarding the expected duration of tube function, recommended follow-up schedule, and detection of complications; (13) clinicians should not routinely prescribe postoperative antibiotic ear drops after tympanostomy tube placement; (15) clinicians should not encourage routine, prophylactic water precautions (use of earplugs or headbands, avoidance of swimming or water sports) for children with tympanostomy tubes.The GUG offered the following KASs as options: (4) clinicians may perform tympanostomy tube insertion in children with unilateral or bilateral OME for 3 months or longer (chronic OME) AND symptoms that are likely attributable, all or in part, to OME that include, but are not limited to, balance (vestibular) problems, poor school performance, behavioral problems, ear discomfort, or reduced quality of life; (9) clinicians may perform tympanostomy tube insertion in at-risk children with unilateral or bilateral OME that is likely to persist as reflected by a type B (flat) tympanogram or a documented effusion for 3 months or longer; (11) clinicians may perform adenoidectomy as an adjunct to tympanostomy tube insertion for children with symptoms directly related to the adenoids (adenoid infection or nasal obstruction) OR in children aged 4 years or older to potentially reduce future incidence of recurrent otitis media or the need for repeat tube insertion.

Abstract
Aim: The aim of this study was to analyze newborn hearing screening test results of children with Down syndrome (DS). Methods: The files of 84 children with DS and 84 healthy children (control group) admitted to the Pediatrics Polyclinics of the Konya Training and Research Hospital between January 2017 and June 2020 were retrospectively reviewed. Results: Thirty-one of the 84 babies with DS were female (36.9%), and 53 were male (63.1%); 37 of the 84 babies in the control group were female (44%), and and 47 were male (56%) (P = .346). Fortty-eight (57.1%) of the 84 babies with DS and 17 (20.2%) of the 84 babies in the control group failed the first screening test (P < .001). It was determined that 24 (50%) of the 48 infants with DS who failed the first test also failed the second test and were referred, and all 17 infants in the control group who failed the first test passed the second test (P < .001). There was no significant difference in terms of birth weight, gestational week, and maternal age between infants with DS who failed and passed after the second screening test (P > .05 for all). Conclusion: Our study shows that birth weight, gestational age, and maternal age do not pose an additional risk for hearing loss in DS babies who do not have known risk factors for hearing loss.

Abstract
Down syndrome (DS) is a unique genetic disease caused by the presence of an extra copy of chromosome 21, which carries four of the six interferon receptor (IFN-R) genes on its long arm. Recent studies reporting higher levels of interferon-stimulated gene (ISG) expression in primary immune cells studied ex vivo have suggested that the additional copies of the IFN-R genes in DS result in mild interferonopathy. In this review, we analyze the potential clinical and immunological impacts of this interferonopathy in DS. We performed a literature review to explore the epidemiology and risks of celiac disease, type 1 diabetes, thyroid dysfunction, mucocutaneous manifestations, infectious diseases (including COVID-19), and Alzheimer’s disease in individuals with DS relative to the general population with or without iatrogenic exposure to interferons. We analyzed immunophenotyping data and the current experimental evidence concerning IFN-R expression, constitutive JAK-STAT activation, and ISG overexpression in DS. Despite the lack of direct evidence that implicating this mild interferonopathy directly in illnesses in individuals with DS, we highlight the challenges ahead and directions that could be taken to determine more clearly the biological impact of interferonopathy on various immune-related conditions in DS.

Abstract
Down syndrome (DS), trisomy 21, results in many complex phenotypes including cognitive deficits, heart defects and craniofacial alterations. Phenotypes arise from an extra copy of human chromosome 21 (Hsa21) genes. However, these dosage-sensitive causative genes remain unknown. Animal models enable identification of genes and pathological mechanisms. The Dp1Tyb mouse model of DS has an extra copy of 63% of Hsa21-orthologous mouse genes. In order to establish whether this model recapitulates DS phenotypes, we comprehensively phenotyped Dp1Tyb mice using 28 tests of different physiological systems and found that 468 out of 1800 parameters were significantly altered. We show that Dp1Tyb mice have wide-ranging DS-like phenotypes, including aberrant erythropoiesis and megakaryopoiesis, reduced bone density, craniofacial changes, altered cardiac function, a pre-diabetic state, and deficits in memory, locomotion, hearing and sleep. Thus, Dp1Tyb mice are an excellent model for investigating complex DS phenotype-genotype relationships for this common disorder.

Abstract
OBJECTIVES Children with Down syndrome (DS) have a higher incidence of tympanostomy tube insertion (TTI) than children in the general population. As there were no studies investigating factors that are associated with multiple TTIs in children with DS, we sought to determine what factors increase or decrease the likelihood of repeat TTI in children with DS. METHODS A retrospective case-control study was performed on consecutive children with DS from 2007 to 2018 with first TTI at a large tertiary children's hospital and follow-up duration at least 27 months since first TTI. RESULTS 277 patients met the inclusion criteria. Repeat TTI rate was 61.4%. Having an indication of chronic otitis media with effusion (COME) at first TTI was an adjusted risk factor for increased rate of repeat TTI (OR: 2.01, 95%CI: 1.15-3.51, p = .014), while being older at first TTI was an adjusted protective factor for decreased rate of repeat TTI (OR: 0.84, 95%CI: 0.74-0.95, p = .004). Adenotonsillectomy at or before first TTI was not an adjusted protective factor for decreased rate of repeat TTI (OR: 0.915, 95%CI: 0.448-1.872, p = .809) and bilateral intra-operative fluid was not an adjusted risk factor for repeat TTI (OR: 1.97, 95%CI: 0.99-3.90, p = .054). CONCLUSION Children with DS were more likely to undergo repeat TTI if they were of younger age and if the indication for surgery was COME. The repeat TTI rate for children with DS was high at 61.4%. Prospective studies are warranted to more precisely investigate factors associated with repeat TTIs in this unique patient population.

Abstract
Down syndrome (DS) is the most common genetic cause of Alzheimer's disease (AD) due to trisomy for all or part of human chromosome 21 (Hsa21). It is also associated with other phenotypes including distinctive facial features, cardiac defects, growth delay, intellectual disability, immune system abnormalities, and hearing loss. All adults with DS demonstrate AD-like brain pathology, including amyloid plaques and neurofibrillary tangles, by age 40 and dementia typically by age 60. There is compelling evidence that increased APP gene dose is necessary for AD in DS, and the mechanism for this effect has begun to emerge, implicating the C-terminal APP fragment of 99 amino acid (β-CTF). The products of other triplicated genes on Hsa21 might act to modify the impact of APP triplication by altering the overall rate of biological aging. Another important age-related DS phenotype is hearing loss, and while its mechanism is unknown, we describe its characteristics here. Moreover, immune system abnormalities in DS, involving interferon pathway genes and aging, predispose to diverse infections and might modify the severity of COVID-19. All these considerations suggest human trisomy 21 impacts several diseases in an age-dependent manner. Thus, understanding the possible aging-related mechanisms associated with these clinical manifestations of DS will facilitate therapeutic interventions in mid-to-late adulthood, while at the same time shedding light on basic mechanisms of aging.

Abstract
INTRODUCTION & OBJECTIVE Children with cognitive delay often experience challenges with obtaining hearing thresholds through behavioral audiometry (BA). This necessitates sedated Auditory Brainstem Response (sABR) testing. This study aimed to evaluate diagnostic and hearing patterns in children with Down Syndrome (DS), Autism Spectrum Disorder (ASD), Global Developmental delay (GDD), and Cerebral Palsy (CP) who were unable to complete reliable BA testing due to severe cognitive delay. METHODS Retrospective chart review on a cohort of children aged 0.5-18 years with a diagnosis of DS, ASD, GDD, or CP who underwent sABR due to unsuccessful BA testing. This was performed at a tertiary care institution from 2014 to 2019. Testing patterns and audiometric data were collected. RESULTS Across 15 DS, 39 ASD, 10 GDD, and 11 CP patients, the average time from first nondiagnostic BA to sABR ranged from 8.6 months (in GDD) to 21.8 months (in DS). The average number of BAs performed before sABR ranged from 1.6 (in ASD and GDD) to 2.7 (in DS). Hearing loss (HL) was diagnosed in 10%, 13%, 36% and 46% of patients with GDD, ASD, CP and DS respectively. Up to 75% of the HL was sensorineural (in CP patients). CONCLUSION In children with significant cognitive delays, a high incidence of HL (especially SNHL) was identified, therefore high suspicion for HL should be held in these patients. Multiple unsuccessful BAs contribute to prolonged time to diagnosis and treatment, thus prompt sABR should be performed in patients whose severe cognitive delay inhibits reliable testing with BA.

Abstract
BACKGROUND Patients with Down Syndrome (DS) exhibit less efficient and unstable standing postural control. The specificities of somatosensorial deficits might result in a different utilization of resources and in distinct whole-body kinematic patterns, to date still unexplored. In this paper we aim at addressing multi-segmental coordination patterns in people with DS while maintaining standing balance under different visual conditions (open and closed eyes). METHODS This cross-sectional observational cohort study involved two groups of 23 patients with DS and 12 healthy controls. A 30-s standing balance test allowed to extract (i) the length of the trajectory of the center-of-pressure sway and 95% confidence ellipse area from Ground Reaction forces, and (ii) Principal Movement (PM) components from full-body motion kinematics; the latter were obtained exploiting a Principal Component Analysis-based approach, also embracing a motor-control perspective through the evaluation of the number of modifications applied by the neuromuscular controller on segments' acceleration. FINDINGS Trajectory length was significantly higher in patients; 95% ellipse confidence area did not differ between groups/condition. Postural movement components differed in people with DS from healthy controls not only in the "observable", behavioural phenotype (PM3 and PM8), but also in the amount of activation of the associated control (PM1 to PM8, over-activated in DS) in all spatial directions. INTERPRETATION Results reinforced the prevalence of a medio-lateral hip strategy (instead of an ankle strategy) in maintaining postural stability. Most important, they revealed a less frequent activation of postural patterns in all spatial directions.

Abstract
OBJECTIVES Trisomy 21 is the most common chromosomal abnormality in the United States with an incidence of 1 in 700 in live-born children. Children with trisomy 21 are at increased risk for chronic ear disease, as well as other medical issues that may complicate healthcare access. In this study, we investigate whether children with trisomy 21 experience delays in tympanostomy tube insertion, and if there are any factors that contribute to a delay in care. METHODS We performed a retrospective analysis on patients with trisomy 21 undergoing tympanostomy tube insertion at Boston Medical Center between 2005 and 2019 by analyzing the electronic medical record. This cohort was matched to patients without trisomy 21 by age, gender, surgery date and surgeon. The primary outcome was time elapsed between surgery decision date and date of tympanostomy tube insertion. RESULTS A total of 20 patients with trisomy 21 underwent tympanostomy tube insertion at Boston Medical Center between 2005 and 2019. The trisomy 21 cohort was matched to 39 patients in the general population. The average time elapsed from decision to undergo surgery to tympanostomy tube insertion was 43.1 days in the general population and 119.0 days in the trisomy 21 cohort (p < .01). CONCLUSION Patients with trisomy 21 experience greater delays in tympanostomy tube insertion than the general population, which may be due to the increased burden of comorbid conditions in people with trisomy 21.

Abstract
Purpose Normative data regarding behavioral audiologic testing procedures are based upon the general population and often do not apply to children with Down syndrome (DS). Testing children with DS can be challenging, and outcomes may be unreliable due to their different cognitive demands and delays. The aim of this study was to assess optimal audiologic testing procedures for specific age groups of children with DS. Method This study used a retrospective investigation of 273 children with DS (145 boys, 128 girls; average age at evaluation = 5.92 ± 4.74 years) who received an audiologic evaluation during 2013 as part of their medical care at a large pediatric hospital (satellite facilities included). Results Age ranges for the completion of audiometry procedures in children with DS are provided. Average age to reliably complete behavioral testing in children with DS was delayed by up to 30 months compared to typically developing children. The majority of children with DS achieved at least good-to-fair reliability for audiologic results starting at 16 months (85.7%) and two ear results at 6-10 years (76.1%). Though not statistically significant, the use of a two-tester assistant compared to a single tester appeared to be helpful in obtaining reliable results. Conclusion The results provide a guide to optimal audiologic test procedures for children with DS, as the standard audiologic guidelines for typically developing infants and children do not apply.

Hargunani CA, King E, Milczuk HA, MacArthur CJ. Endoscopic ear surgery in children with down syndrome. Int J Pediatr Otorhinolaryngol 2020; 131:109884. [PMID: 31972386 DOI: 10.1016/j.ijporl.2020.109884] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Revised: 01/06/2020] [Accepted: 01/13/2020] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Children with Down syndrome (DS) have a high incidence of chronic middle ear disease. Surgery to manage this disease is challenging due to the severity of illness and narrow ear canal dimensions. Endoscopic ear surgery is used to manage tympanic membrane and middle ear disease with the advantages of improved visualization and avoidance of post-auricular incisions. However, its application in children with DS has not been reported. We aim to compare the outcomes of endoscopic versus microscopic ear surgery in children with DS. METHODS All patients with DS who underwent tympanoplasty without mastoidectomy between 2012 and 2018 were identified, and their charts retrospectively reviewed. Rate of residual perforation, hearing, surgical time, and surgical details were recorded. RESULTS 37 surgeries in 26 patients were identified that met inclusion criteria. Two subgroups were analyzed. The first included 14 cases that were done using traditional microscopic visualization (MV). The second included 17 cases that had substantial or exclusive use of endoscopic visualization (EES). Due to a learning curve, the number of cases done endoscopically increased over time. The average age in MV was 13.9 years vs 11.0 in EES. The MV cases included 2 with cholesteatoma vs 4 in EES. In cases with adequate follow up, residual perforations were found in 1/13 MV, and 4/17 EES. All of the residual perforation cases in EES used acellular porcine submucosa grafts. None of the cases in MV used this material. Average air bone gap reduction was seen in both groups; 4.2 dB in MV, 9.8 dB in EES. Average surgical time was similar between groups; 124 min in MV, 115 min in EES. All cases in MV required a post-auricular incision and approach to the middle ear. Only four cases in EES required this approach. Six cases in EES did not require any incision outside of the ear canal for either graft harvest or middle ear approach. CONCLUSION Endoscopic and microscopic ear surgery in children with DS have similar outcomes. There were no statistical differences in hearing results, surgical times, or residual tympanic membrane perforations, although the rate of perforations in the endoscopic group trended higher. Most endoscopic cases did not require conversion to a post-auricular approach. Endoscopic surgery allows some DS patients to avoid any incision outside of the ear canal.

Abstract
Trisomy 21, the presence of a supernumerary chromosome 21, results in a collection of clinical features commonly known as Down syndrome (DS). DS is among the most genetically complex of the conditions that are compatible with human survival post-term, and the most frequent survivable autosomal aneuploidy. Mouse models of DS, involving trisomy of all or part of human chromosome 21 or orthologous mouse genomic regions, are providing valuable insights into the contribution of triplicated genes or groups of genes to the many clinical manifestations in DS. This endeavour is challenging, as there are >200 protein-coding genes on chromosome 21 and they can have direct and indirect effects on homeostasis in cells, tissues, organs and systems. Although this complexity poses formidable challenges to understanding the underlying molecular basis for each of the many clinical features of DS, it also provides opportunities for improving understanding of genetic mechanisms underlying the development and function of many cell types, tissues, organs and systems. Since the first description of trisomy 21, we have learned much about intellectual disability and genetic risk factors for congenital heart disease. The lower occurrence of solid tumours in individuals with DS supports the identification of chromosome 21 genes that protect against cancer when overexpressed. The universal occurrence of the histopathology of Alzheimer disease and the high prevalence of dementia in DS are providing insights into the pathology and treatment of Alzheimer disease. Clinical trials to ameliorate intellectual disability in DS signal a new era in which therapeutic interventions based on knowledge of the molecular pathophysiology of DS can now be explored; these efforts provide reasonable hope for the future.

Abstract
OBJECTIVE The aim of the study was to analyze the long-term outcomes after cochlear implantation in deaf children with Down syndrome (DS) regarding age at the first implantation and refer the results to preoperative radiological findings as well as postoperative auditory and speech performance. Additionally, the influence of the age at implantation and duration of CI use on postoperative hearing and language skills were closely analyzed in children with DS. STUDY DESIGN Retrospective analysis. SETTING Referral center (Cochlear Implant Center). MATERIALS AND METHODS Nine children with Down syndrome were compared with 220 pediatric patients without additional mental disorders or genetic mutations. Patients were divided into four categories depending on the age of the first implantation: CAT1 (0-3 yr), CAT2 (4-5 yr), CAT3 (6-7 yr), and CAT4 (8-17 yr). The auditory performance was assessed with the meaningful auditory integration scales (MAIS) and categories of auditory performance (CAP) scales. The speech and language development were further evaluated with meaningful use of speech scale (MUSS) and speech intelligibility rating (SIR). The postoperative speech skills were analyzed and compared between the study group and the reference group by using nonparametric statistical tests. Anatomic abnormalities of the inner ear were examined using magnetic resonance imaging (MRI) and high-resolution computed tomography of the temporal bones (HRCT). RESULTS The mean follow-up time was 14.9 years (range, 13.1-18.3 yr). Patients with DS received a multichannel implant at a mean age of 75.3 months (SD 27.9; ranging from 21 to 127 mo) and 220 non-syndromic children from reference group at a mean age of 51.4 months (SD 34.2; ranging from 9 to 167 mo). The intraoperative neural response was present in all cases. The auditory and speech performance improved in each DS child. The postoperative mean CAP and SIR scores were 4.4 (SD 0.8) and 3.2 (SD 0.6), respectively. The average of scores in MUSS and MAIS/IT-MAIS scales was 59.8% (SD 0.1) and 76.9% (SD 0.1), respectively. Gathered data indicates that children with DS implanted with CI at a younger age (<6 years of age) benefited from the CI more than children implanted later in life, similarly in a control group. There were additional anomalies of the temporal bone, external, middle, or inner ear observed in 90% of DS children, basing on MRI or HRCT. CONCLUSIONS The early cochlear implantation in children with DS is a similarly useful method in treating severe to profound sensorineural hearing loss (SNHL) as in non-syndromic patients, although the development of speech skills present differently. Due to a higher prevalence of ear and temporal bone malformations, detailed diagnostic imaging should be taken into account before the CI qualification. Better postoperative outcomes may be achieved through comprehensive care from parents/guardians and speech therapists thanks to intensive and systematic rehabilitation.

Abstract
BACKGROUND The prevalence and causes of sensorineural hearing loss (SNHL) in children with Down syndrome (DS) are poorly delineated. OBJECTIVE To describe the prevalence, severity, laterality and underlying etiology of SNHL in a cohort of children with DS. METHODS A cross-sectional study was performed among all children with DS followed at the multidisciplinary Downteam of the Antwerp University Hospital. Patients' characteristics, risk factors for hearing loss, audiometric data and results of an etiological work-up were collected. RESULTS Among 291 patients in follow-up, 138 patients (47.4%) presented with hearing loss. In the majority this was caused by middle ear effusion and only 13 patients (4.5%) had sensorineural hearing loss, 7 boys and 6 girls with a mean age of 14.4 ± 7.4 years. Hearing loss was bilateral in 8 cases. Hearing loss severity was graded as mild in 38.5%, moderate in 30.8% and profound in 30.8% of the patients. An etiological work-up was completed in 9 children. Four patients presented with single sided deafness due to cochlear nerve deficiency. One patient had a genetic cause and in 2 patients the hearing loss was attributed to excessive noise exposure. The etiology of hearing loss was unknown in 6 patients. CONCLUSION Sensorineural hearing loss is uncommon in children with DS with a prevalence of 4.5%. Etiological work-up may allow identifying a specific underlying cause. Cochlear nerve deficiency was found in 4 children with DS and single sided deafness.

Abstract
Objective The aim was to examine whether the presence of pain (based on physical conditions and participants' report) and self-reported pain experience in adults with Down syndrome (DS) differ from general population controls. Design Cross-sectional study of 224 adults with DS (mean age = 38.1 years, mild-severe intellectual disabilities) and 142 age-matched controls (median age = 40.5 years, mean estimated IQ = 105.7) in the Netherlands. Methods File-based medical information was evaluated. Self-reported presence and experience of pain were assessed in rest and after movement during a test session (affect with facial affective scale (FAS: 0.04-0.97), intensity assessed with numeric rating scale (NRS: 0-10). Results Compared with controls, more DS participants had physical conditions that may cause pain and/or discomfort ( p = .004, 50% vs 35%), but fewer DS participants reported pain during the test session ( p = .003, 58% vs 73%). Of the participants who indicated pain and comprehended self-reporting scales ( n = 198 FAS, n = 161 NRS), the DS group reported a higher pain affect and intensity than the controls ( p < .001, FAS: 0.75-0.85 vs 0.50-0.59, NRS: 6.00-7.94 vs 2.00-3.73). Conclusions Not all adults with DS and painful/discomforting physical conditions reported pain. Those who did indicated a higher pain experience than adults from the general population. Research into spontaneous self-report of pain, repeated pain assessment, and acute pain is needed in people with DS for more insight into pain experience and mismatches between self-report and medical information.

Abstract
INTRODUCTION The high incidence of chronic otitis media with effusion and Eustachian tube dysfunction in children with Down syndrome (DS) may predispose them to cholesteatoma formation. Establishing the diagnosis, choosing the appropriate operative intervention, and post-operative care can be challenging. OBJECTIVE To describe management strategies for cholesteatoma diagnosis, surgical treatment, and post-operative management in children with Down syndrome. METHODS Retrospective case series of 14 patients (17 total ears) with Down syndrome diagnosed with cholesteatoma over a 9-year period. RESULTS A total of 14 patients with cholesteatoma (3 with bilateral disease) were analyzed. Thirteen ears (76.5%) had ≥2 tympanostomy tubes insertions prior to cholesteatoma diagnosis, and otorrhea and hearing loss were the most common presenting symptoms. Common pre-operative CT scan findings included mastoid sclerosis and ossicular erosion. The average age at first surgery was 9.8 years, and the average follow-up was 4.3 years. For acquired cholesteatoma, most ears were managed with canal wall up (CWU) approaches, but ultimately 6/15 (40.0%) required canal wall down (CWD) approaches. Postoperatively, 3 (20.0%) ears developed new tympanic membrane retraction pockets, but no recurrent cholesteatoma. Four (26.7%) ears developed recurrent disease, and 3 (20.0%) had residual disease at secondary procedures. Ossiculoplasty was performed in 4 ears. Twelve (70.6%) ears were rehabilitated with hearing aids or FM systems. CONCLUSIONS The diagnosis of cholesteatoma in Down syndrome was associated with otorrhea, hearing loss, and CT scan findings of ossicular erosion and mastoid sclerosis. Most cases were managed with CWU surgical approaches. Hearing aid use was common post-operatively.

Abstract
OBJECTIVES To evaluate hearing impairment in children with Down syndrome, and to describe the factors that influence the severity of hearing loss or changes in hearing over time. STUDY DESIGN Using the Audiological and Genetic Database (AudGenDB), audiograms of children with Down syndrome were analyzed retrospectively for type, severity, and laterality of hearing loss, as well as changes over time. Medical charts and imaging results were reviewed to identify factors influencing hearing loss. RESULTS Among the 1088 patients with Down syndrome included in the study, 921 had hearing loss in at least 1 ear, 91.1% had bilateral hearing loss, and 8.9% had unilateral hearing loss (1760 total ears with hearing loss). Of the ears with hearing loss, 18.8% (n = 180) had moderate or worse hearing loss. "Undefined" hearing loss and pure conductive hearing loss (CHL) were the most common types, followed by mixed hearing loss and sensorineural hearing loss (SNHL). Three-quarters (75.4%) of the children had experienced chronic otitis media or more than 2 episodes of acute otitis media. Patients with bilateral, mixed hearing loss or a history of seizures were at risk for more severe hearing loss. CHL, absence of cholesteatoma, and placement of first ear tubes before age 2 years were associated with greater improvement in hearing over time, whereas SNHL and mixed hearing loss were associated with progressive decline. CONCLUSION Children with Down syndrome who have bilateral, mixed hearing loss or a history of seizures are at risk for more severe hearing loss. SNHL and mixed hearing loss should not be overlooked in patients with CHL. All patients with Down syndrome will benefit from serial audiograms, especially those children with SNHL or mixed hearing loss, which is likely to worsen over time.

Abstract
PURPOSE This study evaluated the prevalence of permanent and transient hearing loss, the use of hearing aids as a recommendation, and middle ear dysfunction in children with Down syndrome (DS) through a large multiage and ethnically diverse sample, using current audiologic testing practices. METHOD Retrospective analysis of data collected on 308 children with DS (168 boys, 140 girls; average age = 5.99 ± 4.88 years) who received an audiological evaluation during 2013 as part of their medical care at a large pediatric hospital. RESULTS Permanent hearing loss was identified in 24.9% of the children, among whom bilateral (75.4%) and conductive (33.3%) hearing losses occurred most often. Of children with DS, 22%-30% experienced a transient hearing loss, with a high incidence of middle ear pathologies from infancy until early adulthood. There were no statistical differences between ethnicity and permanent/transient hearing loss diagnosis. Twenty-three percent were current hearing aid users or had them recommended in a treatment plan. CONCLUSIONS The prevalence of hearing loss and abnormal middle ear status is high in the pediatric population with DS. Audiologic evaluations should follow the American Academy of Pediatrics practice guidelines to monitor this high-risk population, and amplification should be considered as an appropriate intervention option if repeated audiologic examinations reveal hearing loss.

Abstract
Increased life expectancy in persons with Down syndrome (DS) is associated with premature age-related changes. The aim of this study was to assess auditory function in adults with DS and to evaluate the prevalence of hearing loss in this population. Audiometric tests were performed in 72 adults with DS (mean age 37.3±10.1 years, 51.4% females). Air conduction pure tone average (PTA) thresholds at frequencies 0.5-1-2-4 kHz were calculated to assess hearing function. Hearing loss was present if the PTA threshold was > 20 dB hearing level. Higher frequencies of 4 and 8 kHz were also assessed. Hearing loss was shown in 47 (65.3%) participants. The prevalence of hearing loss increased with age, ranging from 42.86% in the 20-29 years group to 90.91% in the 50-59 years group. High frequencies (4 and 8 kHz) were more often impaired than other frequencies used to measure PTA. Thus, the study concluded hearing loss is common in adults with DS and shows a pattern compatible with precocious aging of the hearing system. Auditory evaluation is strongly recommended in adults with DS.

Abstract
OBJECTIVE The purpose of this study was to evaluate pressurised wideband acoustic immittance (WAI) tests in children with Down syndrome (DS) and in typically developing children (TD) for prediction of conductive hearing loss (CHL) and patency of pressure equalising tubes (PETs). DESIGN Audiologic diagnosis was determined by audiometry in combination with distortion-product otoacoustic emissions, 0.226 kHz tympanometry and otoscopy. WAI results were compared for ears within diagnostic categories (Normal, CHL and PET) and between groups (TD and DS). STUDY SAMPLE Children with DS (n = 40; mean age 6.4 years), and TD children (n = 48; mean age 5.1 years) were included. RESULTS Wideband absorbance was significantly lower at 1-4 kHz in ears with CHL compared to NH for both TD and DS groups. In ears with patent PETs, wideband absorbance and group delay (GD) were larger than in ears without PETs between 0.25 and 1.5 kHz. Wideband absorbance tests were performed similarly for prediction of CHL and patent PETs in TD and DS groups. CONCLUSIONS Wideband absorbance and GD revealed specific patterns in both TD children and those with DS that can assist in detection of the presence of significant CHL, assess the patency of PETs, and provide frequency-specific information in the audiometric range.

Abstract
The centromere is responsible for the correct inheritance of eukaryotic chromosomes during cell division. Centromere protein B (CENP‑B) and its 17 base pair binding site (CENP‑B box), which appears at regular intervals in centromeric α-satellite DNA (α-satDNA), are important for the assembly of the centromere components. Therefore, it is conceivable that CENP-B box mutations may induce errors in cell division. However, the association between the deoxynucleotide alterations of the CENP‑B box and the extra chromosome 21 (Chr21) present in patients with Down syndrome (DS) remains to be elucidated. The mutational spectrum of the α‑satDNA, including 4 functional CENP‑B boxes in Chr21 from 127 DS and 100 healthy children were analyzed by direct sequencing. The de novo occurrences of mutations within CENP‑B boxes in patients with DS were excluded. The prevalence of 6 novel mutations (g.661delC, g.1035_1036insA, g.1076_1077insC, g.670T>G, g.1239A>T, g.1343T>C) and 3 single nucleotide polymorphisms (g.727C/T, g.863A/C, g.1264C/G) were not significantly different between DS and controls (P>0.05). However, g.525C/G (P=0.01), g.601T/C (P=0.00000002), g.1279A/G (P=0.002), g.1294C/T (P=0.0006) and g.1302 G/T (P=0.004) were significantly associated with the prevalence of DS (P<0.05). The results indicated that CENP‑B boxes are highly conserved in DS patients and may not be responsible for Chr21 nondisjunction events. However, α‑satDNA in Chr21 is variable and deoxynucleotide deletions, mutations and polymorphisms may act as potential molecular diagnostic markers of DS.

Abstract
The clinical practice guideline on otitis media with effusion (OME) provides evidence-based recommendations on diagnosing and managing OME in children. This is an update of the 1994 clinical practice guideline “Otitis Media With Effusion in Young Children,” which was developed by the Agency for Healthcare Policy and Research (now the Agency for Healthcare Research and Quality). In contrast to the earlier guideline, which was limited to children aged 1 to 3 years with no craniofacial or neurologic abnormalities or sensory deficits, the updated guideline applies to children aged 2 months through 12 years with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The American Academy of Pediatrics, American Academy of Family Physicians, and American Academy of Otolaryngology- Head and Neck Surgery selected a subcommittee composed of experts in the fields of primary care, otolaryngology, infectious diseases, epidemiology, hearing, speech and language, and advanced practice nursing to revise the OME guideline. The subcommittee made a strong recommendation that clinicians use pneumatic otoscopy as the primary diagnostic method and distinguish OME from acute otitis media (AOM). The subcommittee made recommendations that clinicians should (1) document the laterality, duration of effusion, and presence and severity of associated symptoms at each assessment of the child with OME; (2) distinguish the child with OME who is at risk for speech, language, or learning problems from other children with OME and more promptly evaluate hearing, speech, language, and need for intervention in children at risk; and (3) manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known), or from the date of diagnosis (if onset is unknown). The subcommittee also made recommendations that (4) hearing testing be conducted when OME persists for 3 months or longer, or at any time that language delay, learning problems, or a significant hearing loss is suspected in a child with OME; (5) children with persistent OME who are not at risk should be reexamined at 3- to 6-month intervals until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected; and (6) when a child becomes a surgical candidate, tympanostomy tube insertion is the preferred initial procedure. Adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); repeat surgery consists of adenoidectomy plus myringotomy, with or without tube insertion. Tonsillectomy alone or myringotomy alone should not be used to treat OME. The subcommittee made negative recommendations that (1) population-based screening programs for OME not be performed in healthy, asymptomatic children and (2) antihistamines and decongestants are ineffective for OME and should not be used for treatment; antimicrobials and corticosteroids do not have long-term efficacy and should not be used for routine management. The subcommittee gave as options that (1) tympanometry can be used to confirm the diagnosis of OME and (2) when children with OME are referred by the primary clinician for evaluation by an otolaryngologist, audiologist, or speech-language pathologist, the referring clinician should document the effusion duration and specific reason for referral (evaluation, surgery), and provide additional relevant information such as history of AOM and developmental status of the child. The subcommittee made no recommendations for (1) complementary and alternative medicine as a treatment for OME based on a lack of scientific evidence documenting efficacy and (2) allergy management as a treatment for OME based on insufficient evidence of therapeutic efficacy or a causal relationship between allergy and OME. Last, the panel compiled a list of research needs based on limitations of the evidence reviewed. The purpose of this guideline is to inform clinicians of evidence-based methods to identify, monitor, and manage OME in children aged 2 months through 12 years. The guideline may not apply to children older than 12 years because OME is uncommon and the natural history is likely to differ from younger children who experience rapid developmental change. The target population includes children with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for use by providers of health care to children, including primary care and specialist physicians, nurses and nurse practitioners, physician assistants, audiologists, speech-language pathologists, and child development specialists. The guideline is applicable to any setting in which children with OME would be identified, monitored, or managed. This guideline is not intended as a sole source of guidance in evaluating children with OME. Rather, it is designed to assist primary care and other clinicians by providing an evidence-based framework for decision-making strategies. It is not intended to replace clinical judgment or establish a protocol for all children with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Abstract
OBJECTIVE To evaluate quality-of-life changes after bilateral pressure equalization tube placement with or without adenoidectomy for the treatment of chronic otitis media with effusion or recurrent acute otitis media in a pediatric Down syndrome population compared to controls. STUDY DESIGN Prospective case-control observational study. METHODS The OM Outcome Survey (OMO-22) was administered to both patients with Down syndrome and controls before bilateral tube placement with or without adenoidectomy and at an average of 6-7 months postoperatively. Thirty-one patients with Down syndrome and 34 controls were recruited. Both pre-operative and post-operative between-group and within-group score comparisons were conducted for the Physical, Hearing/Balance, Speech, Emotional, and Social domains of the OMO-22. RESULTS Both groups experienced improvement of mean symptom scores post-operatively. Patients with Down syndrome reported significant post-operative improvement in mean Physical and Hearing domain item scores while control patients reported significant improvement in Physical, Hearing, and Emotional domain item scores. All four symptom scores in the Speech domain, both pre-operatively and post-operatively, were significantly worse for Down syndrome patients compared to controls (p ≤ 0.008). CONCLUSIONS Surgical placement of pressure equalizing tubes results in significant quality of life improvements in patients with Down syndrome and controls. Problems related to speech and balance are reported at a higher rate and persist despite intervention in the Down syndrome population. It is possible that longer follow up periods and/or more sensitive tools are required to measure speech improvements in the Down syndrome population after pressure equalizing tube placement ± adenoidectomy.

Abstract
OBJECTIVE In 2001, the senior authors published a study investigating hearing loss in young children (ages 11 months to 3.8 years) with Down Syndrome (DS). We re-visit this same study population to review current audiologic status, the incidence of pressure equalization tube (PET) placement(s), and rate of tympanic membrane (TM) perforations. We aim to better understand the natural history of ear disease and hearing loss in DS and assess potential complications. METHODS This retrospective chart review included 57 children with DS who previously completed in 2006, a 5 year, longitudinal study investigating otolaryngologic problems in DS. Updated audiologic data was available for 54. Audiograms, age of ear specific testing, PET placement(s), and tympanic membrane(TM) descriptions were reviewed. RESULTS Ages ranged from 14 to 18 years (mean 16.34 years). PET placement occurred in 88.8%, with mean of 3.5 procedures. 30% of PET's were placed after age 6. Ear specific testing was obtained in 92.5% (mean age 4.54 years). Normal hearing was present in 44% (right ear) and 38% (left ear). "Functional" hearing levels, defined as normal or mild hearing loss and speech reception threshold ≤ 30 dB, occurred in 83.3%. Sensorineural/mixed hearing loss was present in 11% (right ear) and 9% (left ear). TM perforations rate was 17%. No cholesteatomas were found. CONCLUSION Chronic otitis media and indications for PET's persist as children with DS age. Although functional hearing occurred in 83.3%, there was an overall decrease in hearing levels as the children aged. Tympanic membrane perforations occurred in 17%. Continued surveillance of otologic and audiologic status in patients with Down syndrome is recommended.

Abstract
OBJECTIVE Children with Down syndrome (DS) have a high incidence of middle ear disorders and congenital abnormalities of the external, middle and inner ear. Energy reflectance (ER), a wideband acoustic immittance (WAI) measurement parameter, can measure the sound energy reflected or absorbed in the ear canal over a wider range of frequencies more efficiently and faster than conventional single-tone 226 Hz tympanometry. The aim of the present study was to compare the WAI measurements of children with DS with those of typically developing, normal-hearing children according to their tympanometric findings. METHODS Four groups of children with Down syndrome (age range: 2 years and 4 months to 16 years and 3 months; mean age: 8.5 yr) with normal tympanograms (19 ears), flat tympanograms (13 ears), mild negative pressure tympanograms (6 ears between -100 and -199 daPa at the admittance peak) and severe negative pressure tympanograms (4 ears at -200 daPa or lower at the admittance peak) were assessed. All findings were compared with data obtained from 21 ears of a healthy control group (age range: 3 years and 1 month to 13 years and 11 months; mean age: 7.9 yr). The subjects underwent tympanometry with a 226-Hz probe tone frequency and ER measurements along the 200-6,000 Hz range with a chirp stimulus using the Middle-Ear Power Analyzer (MEPA3 - HearID) by Mimosa Acoustics (Champaign, IL), software, version 3.3 [38]. RESULTS Statistically significant differences were observed in the ER curves for some comparisons between the studied groups. There was also a negative correlation between the static acoustic admittance at the tympanic membrane level and ER measured with a chirp stimulus at 500 and 1,000 Hz. The discriminant analysis technique, which used a chirp stimulus at 1,000 and 1,600 Hz to classify the participants' data based on ER values, achieved a correct classification rate of 59.52% for participants with DS. CONCLUSION While groups with abnormal middle ear status, as indicated by tympanometry, showed higher ER values compared to the DS tymp A group and the control group, similar reflectance curves were observed between control group and the DS tymp A group. WAI shows promise as a clinical diagnostic tool in investigating the impact of middle ear disorders in DS group. However, further research is required to investigate this issue in narrower age range group and a larger sample size.

Abstract
OBJECTIVES To report the prevalence of hearing problems and the hearing sequelae in school-aged children with trisomy 21 in a longitudinal study. DESIGN All children with trisomy 21 were identified via schools, community-based child development centres, general practitioners, or the universal newborn hearing screen. Audiological data and otorhinolaryngological problems were prospectively entered in to the Audiological Surveillance Programme database from each visit. SETTING Retrospective review of the Audiological Surveillance Programme database in the Glasgow area (United Kingdom) of all children reviewed between 2004 and 2012. PARTICIPANTS All pre-teenaged children with trisomy 21 of school age (aged 5-12 years old). MAIN OUTCOME MEASURES Hearing thresholds, aetiology of hearing loss and management of hearing loss was determined for the cohort of children. RESULTS A total of 102 children were included. Fifty-four had normal hearing. Twenty-six had fluctuating otitis media with effusion; five had hearing in normal limits, six were managed with hearing aids, fourteen were managed conservatively, and one had ventilation tube insertion. Fifteen had persistent otitis media with effusion; four had ventilation tube insertion; and nine were managed with hearing aids. Seven had mixed hearing loss with four required hearing aids. CONCLUSIONS Otitis media with effusion was the commonest cause of hearing impairment; effusions may fluctuate through the pre-teenaged years, and thus, hearing aids are beneficial. Ventilation tube insertion and bone-conducting hearing aids were useful when ear-level hearing aids were not tolerated. Mixed hearing loss occurred in later years as sensorineural hearing loss developed on a background of otitis media with effusion.
