Purpose: This study aimed to evaluate the incidence of tracheal cartilaginous sleeve (TCS) among syndromic craniosynostosis patients, as well as describe their genetic profiles, associated co-morbidities, and operative outcomes.

Methods: We performed a retrospective analysis of syndromic craniosynostosis patients (Apert, Crouzon, and Pfeiffer) at a single tertiary academic center between January 1, 2002, and February 1, 2024.

Results: 39 patients with syndromic craniosynostosis were identified, with 17 patients (17/39, 43.6%) undergoing airway evaluation. 1 patient (1/17, 5.9%) was diagnosed with TCS, but 5 patients (5/17, 29.4%) had other airway abnormalities, all reflecting abnormalities of the airway wall or some type of airway stenosis. 28 patients (28/39, 73.7%) presented with a diagnosis of OSA, and 7 patients (7/39, 17.9%) of patients presented with choanal anomaly (atresia or stenosis). 32 patients (32/39, 82.1%) had genetic sequencing information available, with the most common mutations affecting p.P253R within the FGFR2 gene in 7 patients. No patients in our cohort presented with a p.W290 mutation and 7 patients presented with a p.C342 mutation, of which 4 patients had the p.C342Y mutation.

Conclusion: The true prevalence of TCS may be likely lower than prior reports, which may aid with alleviating some familial anxiety and provide additional context and data for medical counseling and decision-making. Nonetheless, all patients should be strongly recommended to undergo airway evaluation given the risks associated with TCS, the high prevalence of structural airway anomalies, and the overall low risk of airway evaluation.

目的:本研究旨在评估气管软骨套(TCS)在综合征性颅缝闭塞患者中的发病率,并描述其遗传谱、相关合并症和手术结果。方法:回顾性分析2002年1月1日至2024年2月1日在一个三级学术中心的综合征性颅缝闭锁患者(Apert, Crouzon和Pfeiffer)。结果:39例综合征性颅缝闭锁患者中,17例(17/39,43.6%)接受气道评估。1例(1/17,5.9%)患者被诊断为TCS, 5例(5/17,29.4%)患者有其他气道异常,均反映气道壁异常或某种类型的气道狭窄。28例(28/39,73.7%)患者诊断为OSA, 7例(7/39,17.9%)患者表现为后鼻孔异常(闭锁或狭窄)。32例患者(32/39,82.1%)有基因测序信息,其中最常见的突变影响7例FGFR2基因内的p.P253R。我们的队列中没有患者出现p.W290突变,7例患者出现p.C342突变,其中4例患者出现p.C342Y突变。结论:TCS的真实患病率可能低于之前的报道,这可能有助于减轻一些家庭焦虑,并为医疗咨询和决策提供额外的背景和数据。尽管如此,考虑到TCS的相关风险、结构性气道异常的高患病率以及气道评估的总体低风险,强烈建议所有患者接受气道评估。

Background

Children occasionally adhere their tongues to cold metal surfaces during winter (“tundra tongue”), but little is known about the epidemiology and outcomes of these cases.

Objectives

To explore the following questions: who experiences tundra tongue, under which circumstances does it occur, and what are the outcomes?

Methods

We conducted a scoping review to identify case reports published in historical newspapers from Norway, Sweden and Denmark using national library databases. Epidemiological data were charted manually from newspaper items describing literal frozen tongues.

Results

Among 17,009 unique search hits, 856 reports of 113 different cases were identified. Almost all cases (96 %) involved children, median age 5.25 years, and the majority were boys (63 %). Tongues were most often frozen to railings (40 %). Ambient temperature was reported in 18 cases with a median of −16.5 °C. Outcomes ranged from discomfort to potential amputation of tongue tissue, with 20 (18 %) cases involving a doctor or a hospital. Severe injuries were reported in several cases through three distinct mechanisms: (1) the direct effect of cold on tissue, (2) detachment injuries, and (3) the consequences of immobility.

Conclusion

Children, and especially boys, in wintertime, are vulnerable to tundra tongue. Most cases had no or mild consequences but severe injuries were also described in multiple cases. Hence, parents, health care professionals and policymakers should not underestimate the potential harm of tundra tongue.
背景:儿童在冬季偶尔会将舌头粘在寒冷的金属表面(“苔原舌头”),但对这些病例的流行病学和结果知之甚少。目的:探讨以下问题:谁会经历冻土带舌头,在什么情况下会发生,结果是什么?方法:我们使用国家图书馆数据库对挪威、瑞典和丹麦的历史报纸上发表的病例报告进行了范围综述。流行病学数据是根据报纸上描述冰冻舌头的文字手工绘制的。结果:在17,009个独立搜索命中,确定了113个不同病例的856个报告。几乎所有病例(96%)涉及儿童,中位年龄5.25岁,大多数为男孩(63%)。舌头最常冻僵在栏杆上(40%)。18例报告环境温度中位数为-16.5°C。结果从不适到可能的舌组织截肢不等,其中20例(18%)涉及医生或医院。据报道,在一些病例中,严重的损伤有三种不同的机制:(1)冷对组织的直接影响,(2)脱离损伤,(3)不活动的后果。结论:冬季儿童,尤其是男孩易患冻土带舌病。大多数情况下没有或轻微的后果,但严重的伤害也在多个情况下描述。因此,家长、卫生保健专业人员和决策者不应低估冻土带舌头的潜在危害。

Objective

This study aims to comprehensively assess the timing and accessibility of cochlear implantation, patterns of its utilization, and the associated outcomes related to quality of life (QoL), in children diagnosed with autism spectrum disorder (ASD).

Study design

Retrospective case-control review, and cross-sectional hearing-related QoL survey.

Setting

Tertiary children's hospital.

Methods

This investigation employed a retrospective case-control design, complemented by a cross-sectional hearing-related QoL survey using the HEAR-QL questionnaires. Outcomes were compared between two populations of pediatric cochlear implant recipients: one group with a preoperative diagnosis of ASD and a control group of neurotypical peers. A review of 413 patient records from 2000 to 2022 identified 22 eligible patients with ASD and matched controls. Of these, 16 participants from the ASD group and 16 controls completed the prospective quality-of-life surveys.

Results

The time between the definitive diagnosis of profound sensorineural hearing loss and the cochlear implantation evaluation was longer for patients with ASD. However, no other significant differences in care delays were observed between ASD children and controls, including time to CI qualification, and implantation. Nevertheless, children with ASD aged 2–6 years showed poorer outcomes in social interaction (p = 0.02) and new social situations (p = 0.02 and 0.04). Despite these behavioral differences, no significant disparity in hearing-related QoL-related communication outcomes was observed.

Conclusion

The study shows that cochlear implant benefit children with ASD, with expected challenges not affecting overall success. It underscores the importance of individualized approaches to address delays in CI evaluation, communication, and social interaction challenges. These insights can help guide care teams, parents and educators in setting realistic expectations following cochlear implantation.
目的综合评价自闭症谱系障碍(ASD)儿童人工耳蜗植入的时机、可及性、使用模式以及与生活质量(QoL)相关的结果。研究设计:回顾性病例对照研究和听力相关生活质量横断面调查。设置三级儿童医院。方法本研究采用回顾性病例对照设计,并辅以使用听力- ql问卷进行听力相关生活质量横断面调查。比较两组儿童人工耳蜗受者的结果:一组术前诊断为ASD,对照组为神经正常的同龄人。对2000年至2022年413例患者记录的回顾确定了22例符合条件的ASD患者和匹配的对照组。其中,来自ASD组的16名参与者和对照组的16名参与者完成了预期生活质量调查。结果ASD患者从明确诊断为重度感音神经性听力损失到人工耳蜗植入评估的时间较长。然而,在ASD儿童和对照组之间,在护理延迟方面没有观察到其他显著差异,包括CI认证时间和植入时间。然而,2-6岁ASD儿童在社交互动(p = 0.02)和新社会情境(p = 0.02和0.04)方面表现较差。尽管存在这些行为差异,但在听力相关的生活质量相关的沟通结果中没有观察到显著差异。结论:研究表明人工耳蜗对ASD儿童有益,预期的挑战不会影响整体的成功。它强调了个性化方法在解决CI评估、沟通和社会互动挑战中的延迟的重要性。这些见解可以帮助指导护理团队、家长和教育工作者在人工耳蜗植入后设定切合实际的期望。

Background

This study aimed to characterize the Variant profile of the 4 common deafness-causing genes and evaluated the genotype-phenotype correlation of GJB2 c.109G > A variants in a neonatal cohort, providing insights for early diagnosis of congenital hearing loss.

Methods

A total of 47,729 newborns in Shenzhen underwent integrated deafness gene screening (23 common pathogenic variants across GJB2, SLC26A4, MT-RNR1, and GJB3) and two-stage audiometric assessments from January 2022 to November 2024. Participants were stratified into three groups based on GJB2 c.109G > A genotypes: homozygous (Group A, n = 487), compound heterozygous (Group B, n = 87), and heterozygous carriers (Group C, n = 8055). Hearing function was evaluated via otoacoustic emissions (OAE) at 48 h postpartum, with non-passing cases receiving follow-up OAE and auditory brainstem response (ABR) testing at 42 days.

Results

Deafness-associated Variant were detected in 21.56 % (10,291/47,729) of neonates, with GJB2 exhibiting the highest carrier frequency (20.25 %), followed by SLC26A4 (1.44 %), MT-RNR1 (0.28 %), and GJB3 (0.18 %). The GJB2 c.109G > A locus dominated the variant landscape, with a carrier rate of 18.12 % (n = 8649) and an minor allele frequency of 9.57 %. The overall pass rates for the two-stage audiological assessments differed significantly across the groups: 63.66 % (Group A), 70.11 % (Group B), and 98.92 % (Group C). Bilateral hearing impairment predominated in Groups A and B.

Conclusion

The GJB2 c.109G > A Variant represents the most prevalent pathogenic variant in Shenzhen neonates, and the infants carrying deafness-causing genotypes of this variant presents relatively high hearing screening pass rate. Integrated genetic and audiometric screening could enhance early identification of high-risk infants.
背景:本研究旨在研究新生儿队列中4种常见致聋基因的变异谱,并评估GJB2 c.109G > A变异的基因型-表型相关性,为先天性听力损失的早期诊断提供依据。方法:从2022年1月至2024年11月,深圳共有47,729名新生儿接受了综合耳聋基因筛查(GJB2、SLC26A4、MT-RNR1和GJB3的23种常见致病变异)和两阶段听力评估。根据GJB2 C . 109g > A基因型将参与者分为三组:纯合子(A组,n = 487)、复合杂合子(B组,n = 87)和杂合子携带者(C组,n = 8055)。在产后48 h通过耳声发射(OAE)评估听力功能,未通过的病例在产后42天接受随访的OAE和听觉脑干反应(ABR)测试。结果:新生儿中耳聋相关变异检出率为21.56%(10,291/47,729),其中GJB2的检出率最高(20.25%),其次为SLC26A4(1.44%)、MT-RNR1(0.28%)、GJB3(0.18%)。GJB2 c.109G > A基因座在变异格局中占主导地位,携带率为18.12% (n = 8649),等位基因频率为9.57%。两阶段听力学评估的总体通过率在各组之间差异显著:63.66% (A组),70.11% (B组)和98.92% (C组)。结论:GJB2 c.109G > A变异是深圳新生儿中最常见的致病变异,携带该变异致聋基因型的婴儿听力筛查通过率较高。综合遗传和听力筛查可提高高危婴儿的早期识别。

Objective

To identify the ability of optical coherence tomography (OCT) to assist in the diagnosis and treatment of patients presenting to a primary care provider with signs and symptoms suggesting acute otitis media (AOM).

Design-Setting-Participants

An NIH-funded clinical trial was conducted and enrolled 75 children between 1 and under 7 years of age. Children presented with complaints of ear pain or suspected ear infection from their caregiver history to primary care clinics associated with an academic children's hospital. These patients upon presentation were eligible to enroll in the trial. Following a complete history and physical exam, including pneumatic otoscopy (PO), patients were provided with a diagnosis and treatment plan. Diagnoses included: AOM, middle ear effusion without AOM, or no evidence of otitis media with a clear middle ear space. Following this, OCT was performed, and the diagnosis and treatment plan was reassessed using this data.

Results

The diagnosis and/or treatment plan changed for 15.3 % of patients following the use of OCT compared with the initial use of PO. The greatest influence was seen in the patient group with MEE without AOM, with 36 % (5/14) of these patients having their diagnosis and/or treatment plan changed after OCT was employed.

Conclusions

OCT provides an additional adjunct for primary care providers to enhance visualization of the tympanic membrane and middle ear space. This data, in our clinical trial, resulted in enhanced clinical decision making, in particular for patients with MEE who were not diagnosed with AOM on PO.

Introduction: Depending on the habits of the implanting center, the time interval between the surgical procedure and the activation of a cochlear implant varies greatly. Traditionally, the activation occurs several weeks after surgery, particularly in pediatric population. If recent improvements have concern surgical procedures and peri-operative care, early fitting constitutes the next optimization in cochlear implant management; for the past 5 years, we have introduced early fitting with Day 1 activation in the Robert Debré pediatric hospital. This study aims to evaluate the satisfaction of parents regarding early activation of their child's cochlear implant.

Materials and methods: Pediatric patients who underwent an early activation of their cochlear implant between 2021 and 2024 in Robert Debré Hospital were included in the study. A satisfaction questionnaire was handed out to the parents and collected. The questionnaire encompassed informations received before implantation and during the hospital stay, and their feelings regarding early activation, and after hospital discharge.

Results: 68 parents of patients completed the questionnaire: 73.5 % were activated on day 1 of surgery. 60.3 % considered that early activation has not been painful for their child. 53 % of the parents identified a reaction to an auditory stimulus in their child during activation. 44 % were satisfied with the clinical pharmacologist's visit. 92.3 % were satisfied with the early activation procedure, and 97 % with returning home with an activated cochlear implant. They felt well informed before and after the surgery. No major complication was reported amongst our patients.

Conclusion: Parents are satisfied with their child's early activation of the cochlear implant and felt relieved to go home with an activated processor and early data on the proper functioning of the implant.

导语:根据植入中心的习惯,手术过程和人工耳蜗激活之间的时间间隔差别很大。传统上,激活发生在手术后几周,特别是在儿科人群中。如果最近的改进涉及手术程序和围手术期护理,早期安装是人工耳蜗管理的下一个优化;在过去的5年里,我们在Robert debr儿科医院引入了第一天激活的早期适配。本研究旨在评估家长对儿童人工耳蜗早期激活的满意度。材料和方法:2021年至2024年间在Robert debr医院接受人工耳蜗早期激活的儿科患者被纳入研究。家长们收到了一份满意度调查问卷。问卷包含植入前和住院期间收到的信息,以及他们对早期激活和出院后的感受。结果:68名患者家长完成了问卷调查,73.5%的家长在手术第一天被激活。60.3%的人认为早期激活对他们的孩子来说没有痛苦。53%的父母在孩子被激活时识别出了对听觉刺激的反应。44%的人对临床药理学家的来访感到满意。92.3%的人对早期激活程序感到满意,97%的人对带激活人工耳蜗回家感到满意。他们在手术前和手术后都感觉很了解情况。在我们的患者中没有重大并发症的报告。结论:家长对孩子早期激活人工耳蜗感到满意,并对带着激活的处理器和人工耳蜗正常功能的早期数据回家感到放心。

Purpose

Cochlear implantation (CI) significantly improves hearing in individuals with severe to profound sensorineural hearing loss. However, variations in surgical techniques may affect middle and inner ear mechanics. This study explores the effect of transcranial transcanal wall-Veria technique for CI on middle ear mechanics, measured using wideband absorbance (WBA).

Methods

Ten children (4–7 years) who underwent CI using the transcranial Transcanal wall-Veria technique were compared to age- and gender-matched controls with normal-hearing children. Tympanometric measures such as static compliance, tympanometric peak pressure, Ear canal volume, resonance frequency, and wideband absorbance at peak and ambient pressure were measured.

Results

Conventional 226 Hz Tympanometric measures were similar for both CI and Normal hearing groups, showing no significant differences (p > 0.05) between the groups. However, WBA measurements revealed significant changes (p < 0.05) in absorbance across frequencies, particularly at higher frequencies (2000–8000 Hz). The WBA pattern was different, with two maximum absorbance for normal-hearing children, whereas single maxima around 2000 Hz for CI group. Further, WBA at peak pressure differed from ambient pressure in both groups at low and mid-frequencies, with significant differences (p < 0.05) observed only in CI group. These results suggest that the Veria technique causes alterations in middle ear mechanics, specifically in the high-frequency regions.

Conclusions

This study highlights the utility of WBA in detecting subtle, frequency-specific changes in ear mechanics following the Veria CI technique, which may remain undetected by conventional tympanometry. Although functional auditory outcomes such as aided thresholds, speech perception scores, and eSRT were not correlated in this study,the findings underscore the importance of WBA as an advanced diagnostic tools in assessing the impact of surgical techniques on ear function post-CI.
目的:人工耳蜗植入术(CI)可显著改善重度至重度感音神经性听力损失患者的听力。然而,手术技术的变化可能会影响中耳和内耳的力学。本研究探讨了经颅经扫描wall-Veria技术对中耳力学的影响,采用宽带吸光度(WBA)测量。方法:10名4-7岁的儿童使用经颅经scanal wall-Veria技术接受CI,并与年龄和性别匹配的正常听力儿童进行比较。测量了静顺应性、峰值压力、耳道容积、共振频率、峰值压力和环境压力下的宽带吸光度等鼓室测量指标。结果:CI组与正常听力组常规226 Hz鼓室测量值相似,组间无显著差异(p < 0.05)。结论:本研究强调了WBA在检测Veria CI技术后耳力学中细微的频率特异性变化方面的实用性,这可能是传统鼓室测量法无法检测到的。虽然在本研究中,辅助阈值、语音感知评分和eSRT等功能性听觉结果并不相关,但研究结果强调了WBA作为评估手术技术对ci后耳功能影响的先进诊断工具的重要性。
