Hearing loss is an important public health concern worldwide, especially because of the global trend of aging populations. Therefore, simple, effective, and efficient methods of hearing screening within communities are needed. To develop and validate the effectiveness of a novel three-step hand rub hearing screening (3SHRHS) method to efficiently detect and categorize hearing loss severity.

Dominant deafness-onychodystrophy (DDOD) syndrome is a rare genetic disorder characterized by sensorineural hearing loss and the absence or hypoplasia of nails, associated with defects in the ATP6V1B2 gene. This gene defect significantly affects hearing function, leading to congenital severe-to-profound hearing loss. We present the comprehensive cochlear implant (CI) outcome of a 5-year-old child with DDOD syndrome who received bilateral sequential CIs at the ages of 1  and 4 years.

Second, to assess subjective hearing benefits among bilateral sequential CIs, bimodal hearing, and CI-only groups. Lastly, to analyze the prognostic factors affecting CI outcomes in children with bilateral sequential CIs.

Autoimmune inner ear disease (AIED) is an uncommon cause of fluctuating sensorineural hearing loss (SNHL), which is diagnosed by exclusion and required a high index of suspicion. Secondary AIED, which accompanies other autoimmune diseases, occurs in up to 30% of AIED cases. Secondary AIED is a rare manifestation of paraneoplastic syndrome, and the causal malignancy may be occult initially.

This study aimed to investigate the role of hearing aid (HA) usage in language outcomes among preschool children aged 3-5 years with mild bilateral hearing loss (MBHL). The data were retrieved from a total of 52 children with MBHL and 30 children with normal hearing (NH). The association between demographical, audiological factors and language outcomes was examined.

Background: Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a maternally inherited mitochondrial disease that affects various systems in the body, particularly the brain, nervous system, and muscles. Among these systems, sensorineural hearing loss is a common additional symptom.

Methods: A 42-year-old female patient with MELAS who experienced bilateral profound deafness and underwent bilateral sequential cochlear implantation (CIs).

Background: With advances in cochlear implant (CI) technology, prelingual deaf adults may experience improved speech perception and quality of life (QoL). It is still a challenge for Mandarin-speaking CI user with tone recognition due to CI technology focused on intonation language.

Objectives: To evaluate the long-term post-CI auditory performance and social-emotional benefits in prelingual deaf Mandarin-speaking adults and the difference between them and post-lingual deaf adults.

Purpose: Although previous studies have shown the efficacy of cochlear implants (CIs) in older adults, no study written in English has focused on Mandarin-speaking older recipients. Mandarin is a tonal language, it is hard to lip-read and tone recognition for CI users. This study aimed to evaluate the long-term post-CI outcomes in Mandarin-speaking older adults and the difference between them and younger recipients.

The value of kinematic data for skill assessment is being investigated. This is the first virtual reality simulator developed for liver surgery. This simulator was coded in C++ using PhysX and FleX with a novel cutting algorithm and used a patient data-derived model and two instruments functioning as ultrasonic shears.

Article Synopsis
  • Recessive variants in the MYO15A gene are a significant cause of sensorineural hearing impairment (SNHI), and this study focused on understanding the specific hearing features and outcomes related to these variants.
  • The research involved 40 patients with biallelic MYO15A variants, comparing their audiological data and cochlear implantation results based on the presence of N-terminal domain variants.
  • Findings showed that most patients had severe to profound SNHI, with those having N variants showing better hearing levels, and a majority of cochlear implant recipients experienced positive auditory and speech outcomes, highlighting the need for regular hearing assessments.

Article Synopsis
  • The study compared three cochlear implant (CI) sound coding strategies—BioAid, envelope enhancement (EE), and fundamental frequency modulation (F0mod)—with the advanced combination encoder (ACE) to evaluate speech intelligibility using vocoded Mandarin sentences.
  • The researchers assessed speech understanding through objective and subjective tests, finding that the EE strategy outperformed ACE at certain signal-to-noise ratios, especially when combined with BioAid.
  • The results indicate that while the combination of strategies improved scores, the benefits of BioAid, F0mod, and other combinations were not evident in CI simulations, suggesting implications for future CI coding strategy development, particularly for Mandarin.

Umbilical cord-derived mesenchymal stromal cells (UCMSCs) have potential applications in regenerative medicine. UCMSCs have been demonstrated to repair tissue damage in many inflammatory and degenerative diseases. We have previously shown that UCMSC exosomes reduce nerve injury-induced pain in rats.

Cochlear implantation is a reliable and safe tool to rehabilitate patients with severe-to-profound sensorineural hearing loss, who get limited benefits from traditional hearing aids. Electrode misplacement is a rare but significant problem that fails to provide benefits and may cause injury to the nearby structures. We present a case that underwent mastoidectomy first to remove cholesteatoma, followed by cochlear implantation with electrode misplacement into the petrous area, with sustained hearing benefits and without any injury to the surrounding structures.

Mesenchymal stem cells (MSCs) can be isolated from different tissue origins, such as the bone marrow, the placenta, the umbilical cord, adipose tissues, and skin tissues. MSCs can secrete anti-inflammatory molecules and growth factors for tissue repair and remodeling. However, the ability of skin-derived MSCs (SMSCs) to repair cochlear damage and ameliorate hearing loss remains unclear.

Hearing loss, the most common sensory abnormality, is caused by the death of or damage to inner ear hair cells. Genetic mutations are the main cause of hearing loss. We used nex-generation sequencing data released by the Taiwan Biobank to investigate the GJB2 mutation spectrum in 1517 patients.

Many studies have focused on the suppressive effects of cochlear implants (CIs) on loudness of tinnitus. This study aimed to examine the effects of CIs and their activation on changes in loudness and tinnitus and explore other factors associated with this effect. We recruited 26 CI recipients according to specific criteria.

Hearing loss is the most common disorder in the sensory system. Mutations in GJB2 have been reported to be very common in sensorineural hearing loss patients. In this report, we generated an induced pluripotent stem cell (iPSC) line, MMCi001-A, from the peripheral blood mononuclear cells of a 4-year-old male hearing loss patient carrying GJB2 pV37I mutation by using the Sendai virus delivery system.

Degeneration or loss of inner ear hair cells (HCs) is irreversible and results in sensorineural hearing loss (SHL). Human-induced pluripotent stem cells (hiPSCs) have been employed in disease modelling and cell therapy. Here, we propose a transcription factor (TF)-driven approach using ATOH1 and regulatory factor of x-box (RFX) genes to generate HC-like cells from hiPSCs.

Sensorineural hearing loss (SNHL) is a prevalent form of deafness commonly arising from damage to the cochlear sensory hair cells and degeneration of the spiral ganglion neurons. In this study, Sendai virus was used to generate an induced pluripotent stem cell (iPSC) line from a 39-year-old female patient diagnosed with severe-to-profound, non-syndromic SNHL. The patient also carries a A1555G mutation in the mitochondrial 12S ribosome RNA gene (MTRNR1).

Article Synopsis
  • A study aimed to determine if hearing thresholds assessed via auditory brainstem response (ABR) in infants can predict behavioral pure-tone audiometry (PTA) thresholds in children, using data from a newborn hearing screening program in Taiwan.
  • The research included 104 newborns, focusing on their ABR thresholds and subsequent PTA thresholds, analyzed through correlation and regression methods.
  • Results showed a strong correlation (0.76) between ABR and PTA thresholds, suggesting that while ABR can provide a reliable estimate for behavioral PTA in many cases, it is recommended to combine different ABR methods for precise hearing aid fittings and rehabilitation.
