A comparison between pure-tone audiometry and brainstem electric response audiometry was made in 25 children with a conductive hearing loss due to otitis media with effusion. Pure-tone audiometry, including bone and air-conduction thresholds, was recorded using standard procedures. BERA was used to construct a latency-intensity function and from this the conductive hearing loss could be estimated. For all frequencies except for 2000 Hz a good correlation was found between the conductive loss in the pure-tone audiogram and the conductive loss as estimated by BERA. The moderate correlation for 2000 Hz is due to a 'Carhart'-notch-like phenomenon in the pure-tone audiogram.

Disability-Related Disparities in Screening for Intimate Partner Violence During the Perinatal Period: A Population-Based Study.
Womens Health Issues
January 2025
University of Virginia School of Nursing, Charlottesville, Virginia.
Background: Persons with disabilities are at higher risk of experiencing intimate partner violence (IPV) during the perinatal period than persons without disabilities. Although screening for IPV during the perinatal period is recommended by many organizations, little is known about screening rates for IPV by disability status.
Methods: Our objective was to compare rates of IPV screening during the perinatal period among persons with and without disabilities in the United States.
Background: Noise-induced hearing loss (NIHL) in children is a growing public health concern due to increased exposure to high noise levels in various environments. Early intervention is crucial to prevent long-term developmental and social impacts. This study evaluates the effectiveness of earmuffs as a protective intervention in managing NIHL in children.

K M Shah Dental College and Hospital, Sumandeep Vidyapeeth deemed to be University, Waghodia, Vadodara - 391760, India.
Background: Noise sources in paediatric dental offices include machinery and children's cries and screams. Although the presence of occupational noise-induced hearing loss (ONIHL) among dental operators is established, preventive measures such as ear protection devices (EPDs) are not frequently employed as prophylactic intervention. The primary aim of this study was to quantitatively assess the noise levels in paediatric dental clinics and to qualitatively evaluate the operators' perception of noise with and without the use of EPDs.

Department of Ophthalmology, Ningde Municipal Hospital of Ningde Normal University, Ningde, Fujian, China.
Background: With the aging of the population, the deterioration of visual and auditory functions amongst the elderly has attracted much attention. Age-related hearing loss (ARHL) and age-related macular degeneration (AMD) are common eye and ear diseases that seriously affect the quality of life of elderly population.
Methods: This study utilised a whole cohort sampling method, with a total of 713 participants aged 50 years and older in the community from June 2022 to October 2023, resulting in the inclusion of 620 participants.
