Newborn hearing screening(NHS) programs are essential to identify hearing loss early in life and to improve outcomes in children. In Saudi Arabia, the national NHS program has been operational since 2016;however, few studies have evaluated its status, and none have covered all provinces across the country. This cross-sectional retrospective study provides an overview of the program's status across all provinces, focusing on screening coverage rates, referral/fail rates, and follow-up procedures. In 2021, 199,034 newborns were screened, with a coverage rate of 92.6% and an overall referral/fail rate of 1.87%. These performance measures provide a foundation for future progress and improvements. This study highlights the importance of ongoing efforts to enhance the program's effectiveness and sustainability.

目的含有组织抗体的内耳病患者血清与未固定及未脱钙的仓鼠头部冰冻切片反应可避免抗原性的改变,而且在同一张切片上耳蜗以外的组织可以用来对照。方法66份前庭听觉功能障碍或听力正常的患者血清和一份正常人的血清与仓鼠头部切片进行反应,结果抗血管内皮抗体、抗核抗体以及抗线粒体抗体阳性的血清和仓鼠头部切片上的内耳以及其它组织呈现阳性反应。表明患者血清中的这些抗体对内耳来说不是器官特异性的。50例前庭听觉功能障碍的患者血清中只有2例有耳硬化的患者血清在免疫发病机理上可以看作是半器官特异性的。抗内膜抗体和抗平滑肌抗体阳性的血清对内耳组织反应阴性。对头皮肌和镫骨动脉壁及内耳动脉壁有反应。Corti氏器的盖膜显示出非特异性的自身绿色荧光。结论头部切片对于区分器官特异性抗体以及诊断自身免疫性内耳病是一种新的、方便的且安全的技术。单纯的免疫组化测定并没有对内耳疾病的单因素病因学给出一个提示。在使用患者血清中的组织抗体时,其它的额外因素也应该被考虑在内,因为前庭听觉功能障碍在病因学可能是多因素的。

Objective: To describe the clinical and pathologic features of a new dominantly inherited audiovestibular syndrome. Methods: History, examination, and audiometric testing in the proband, brother, and son; quantitative rotational testing in the proband and son; histopathology of the cochlea and vestibular labyrinth in the proband; sequencing candidate genes COCH and MYO7A in the brother and son. Results: Affected family members developed slowly progressive hearing loss beginning in their late 30s and progressive imbalance in their early 70s. Three of four affected had brief (minutes) episodes of vertigo typically occurring a few times per year. Auditory and vestibular function testing documented a slowly progressive loss of auditory and vestibular function. Postmortem examination showed a loss of hair cells in the cochlea and vestibular receptor organs. There were no cellular infiltrates or acidophilic deposits. No mutations were found in the COCH or MYO7A genes. Conclusions: This dominantly inherited audiovestibular syndrome results in a selective loss of hair cells in the auditory and vestibular end organs. Finding the causative gene could have important implications for understanding the pathophysiology of presbycusis and dysequilibrium of aging.
