INTRODUCTION: Juvenile idiopathic arthritis (JIA) is a chronic autoimmune disease characterized by the presence of arthritis in children under 16 years of age for more than 6 weeks in the absence of any other known cause. The extra-articular manifestations, especially in the audiovestibular system, are related to the involvement of the joints of the ossicular chain as a result of the inflammatory process in the synovium. Previous clinical studies in pediatric patients have shown conductive or sensorineural hearing loss...

BACKGROUND: Hearing loss remains a neglected public health issue in the rural and agricultural communities in the United States and therefore, promotion of a low-cost hearing screening may be important for these underserved populations. The major objectives of our study were to assess feasibility of a low-cost telephone-administered hearing test in rural Indiana and to identify the challenges, barriers and viable implementation strategies associated with this test. Also, we evaluated whether a focus group session could change the hearing health attitude of rural residents...

The physiological and behavioural effects of empathy for other's pain have been widely investigated, while the opposite situation, i.e. the influence on one's pain of empathetic feedback from others, remains largely unexplored. Here, we assessed whether and how empathetic and unempathetic comments from observers modulate pain and associated vegetative reactions. In Study 1, conversations between observers of a pain study were recorded by professional actors. Comments were prepared to be perceived as empathetic, unempathetic, or neutral, and were validated in 40 subjects...

INTRODUCTION AND AIM: The reason of gradually developing conductive hearing loss in otosclerotic patients is the ossification of the stapes footplate to the surrounding bony structures and the therapy of stapes fixation is mainly surgical. In stapedotomy the footplate of the stapes is fenestrated with laser and microdrill in a diameter of 0.8 mm, whereas in stapedectomy there is complete removal of the footplate followed by the reconstruction of the ossicular chain. In the early postoperative period, temporary vertigo is frequently recorded which significantly influences the recovery...

Facioscapulohumeral muscular dystrophy is a slowly progressive but devastating myopathy caused by loss of repression of the transcription factor DUX4; however, DUX4 expression is very low, and protein has not been detected directly in patient biopsies. Efforts to model DUX4 myopathy in mice have foundered either in being too severe, or in lacking muscle phenotypes. Here we show that the endogenous facioscapulohumeral muscular dystrophy-specific DUX4 polyadenylation signal is surprisingly inefficient, and use this finding to develop an facioscapulohumeral muscular dystrophy mouse model with muscle-specific doxycycline-regulated DUX4 expression...

BACKGROUND: Despite marked improvements over the last few decades, maternal mortality in Tanzania remains among the world's highest at 454 maternal deaths per 100,000 live births. Many factors contribute to this disparity, such as a lack of attendance at antenatal care (ANC) services and low rates of delivery at a health facility with a skilled provider. The Wazazi Nipendeni (Love me, parents) social and behavioral change communication campaign was launched in Tanzania in 2012 to improve a range of maternal health outcomes, including individual birth planning, timely ANC attendance, and giving birth in a healthcare facility...

BACKGROUND: Hearing and vision impairments are among the most common and disabling comorbidities in people living with dementia. Intervening to improve sensory function could be a means by which the lives of people living with dementia may be improved. However, very few studies have tried to ameliorate outcomes in dementia by improving sensory function. This paper describes the multi-step development of a new intervention designed to support hearing and vision function in people living with dementia in their own homes...

OBJECTIVES: The incidence of sensorineural hearing loss is between 1 and 3 per 1000 in healthy neonates and 2-4 per 100 in high-risk infants. The national universal neonatal hearing screening carried out in Poland since 2002 enables selection of infants with suspicion and/or risk factors of hearing loss. In this study, we assessed the incidence and risk factors of hearing impairment in infants ≤33 weeks' gestational age (wga). METHODS: We analyzed the database of the Polish Universal Newborns Hearing Screening Program from 2010 to 2013...

BACKGROUND: Vestibular-evoked myogenic potentials (VEMPs) are commonly used clinical assessments for patients with complaints of dizziness. However, relatively high air-conducted stimuli are required to elicit the VEMP, and ultimately may compromise safe noise exposure limits. Recently, research has reported the potential for noise-induced hearing loss (NIHL) from VEMP stimulus exposure through studies of reduced otoacoustic emission levels after VEMP testing, as well as a recent case study showing permanent sensorineural hearing loss associated with VEMP exposure...

BACKGROUND: The benefits offered by noise reduction (NR) features on a hearing aid had been studied traditionally using test conditions that set the hearing aids into a stable state of performance. While adequate, this approach does not allow the differentiation of two NR algorithms that differ in their timing characteristics (i.e., activation and stabilization time). PURPOSE: The current study investigated a new method of measuring noise tolerance (Tracking of Noise Tolerance [TNT]) as a means to differentiate hearing aid technologies...

BACKGROUND: Studies have examined listening effort in individuals with hearing loss to determine the extent of the impairment. Regarding cochlear implants (CIs), results suggest that listening effort is improved using bilateral CIs compared to unilateral CIs. Few studies have investigated listening effort and outcomes related to the hybrid CI. PURPOSE: Here, we compared listening effort across three CI groups, and to a normal-hearing control group. The impact of listener traits, that is, age, age at onset of hearing loss, duration of CI use, and working memory capacity, were examined relative to listening effort...

Jay R Lucker
BACKGROUND: Many audiologists believe that auditory processing testing must be carried out in a soundproof booth. This expectation is especially a problem in places such as elementary schools. Research comparing pure-tone thresholds obtained in sound booths compared to quiet test environments outside of these booths does not support that belief. Auditory processing testing is generally carried out at above threshold levels, and therefore may be even less likely to require a soundproof booth...

Burn-McKeown syndrome (BMKS) is a rare syndrome characterized by choanal atresia, prominent ears, abnormalities of the outer third of the lower eyelid, structural cardiac abnormalities, conductive and sensorineural hearing loss, and cleft lip. Recently, causative compound heterozygous variants were identified in TXNL4A. We analyzed an individual with clinical features of BMKS and her parents by whole-genome sequencing and identified compound heterozygous variants in TXNL4A (a novel splice site variant (c.258-2A>G, (p...
