However, these individuals often overlook their hearing loss, resulting in delayed or inadequate treatment. This oversight can lead to a lack of binaural summation and squelch effect, as well as the head shadow effect, which can significantly impact their speech recognition and sound localization abilities, especially in noisy environments.Recently, a groundbreaking Sound Bite™ Pinyin® Bone Conduction Hearing Aid (HA) device has been has been introduced as a viable alternative to traditional percutaneous stimulation hearing assistance devices. This innovative device harnesses bone conduction technology to convey sound vibrations directly to the inner ear via the bones of the jaw and skull, effectively bypassing the air conduction pathway that is commonly compromised in individuals with hearing loss. This report details the evaluation and adjustment process of a HA device worn by a 31-year-old female patient who suffers from a congenital ossicular chain deformity in her right ear, while maintaining normal hearing in her left ear.The report comprehensively covers the hearing thresholds of the 31-year-old female patient on the day of fitting the hearing aid and one month later. It also presents assessments of the hearing aid's performance through the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire, conducted three days after adjustment, one month later, and one year later.Furthermore, the report details the evaluation of the patient's sound localization ability, comparing her performance before and after wearing the hearing aid device. Additionally, it includes measurements of her speech recognition ability for monosyllabic words and Yang Yang Ge words, which are specific tests in the Chinese language, conducted two years after the initial fitting of the hearing aid.The discovery that bone-anchored hearing devices can significantly enhance hearing thresholds in patients with unilateral conductive hearing loss represents a significant milestone. These devices not only improve speech recognition ability but also enhance sound localization in noisy environments. This improvement is accompanied by a high level of subjective satisfaction among patients, indicating a positive impact on their overall quality of life.</p>","PeriodicalId":94336,"journal":{"name":"Journal of otology","volume":"19 4","pages":"207-213"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11701337/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142961023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preschool hearing screening (PHS) is vital to continue screening throughout early childhood. The current practice of PHS in the primary healthcare centers (PHCs) in Saudi Arabia is unknown. The purpose of this study was to investigate PHS in the PHCs. This cross-sectional descriptive study used an in-person-administered questionnaire to collect data. A total of 106 out of 120 participants (male = 61; female = 45) representing the PHCs in Riyadh were interviewed. Most of the participants were aged 31-40 years and held a bachelor's degree as the highest academic qualification with limited years of experience. PHS was mostly performed through subjective measures by asking the parents (71.7%) and the child (65.1%). The audiometric evaluation was conducted for preschool children in only half of the PHCs. General practitioners and nurses usually perform PHS. Substantial gaps in the practice of PHS were identified. The lack of training and appropriate instruments and the need for audiological services were the main challenges. Incorporating robust and objective protocols for PHS into the educational system is a valuable strategy for identifying hearing loss early and reducing its impact through the establishment of effective intervention plans.</p>","PeriodicalId":94336,"journal":{"name":"Journal of otology","volume":"19 4","pages":"214-219"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11701338/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142960962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings reveal that (R)-PFI-2 hydrochloride, a selective inhibitor of the SETD7 enzyme, effectively inhibits the activation of the cochlear NF-κB pathway, suppresses the release of pro-inflammatory factors, and prevents inflammasome assembly.
