Alport Syndrome is a genetic disorder characterized by hematuria, which often leads to renal failure. It may also be accompanied by extra-renal alterations, such as: sensorineural hearing loss, and ocular abnormalities. Dominant forms related to the X chromosome and caused by mutations in the locus COL4A5 have been described, as well as an autossomic recessive form resulting from mutations in t...

Purpose: To investigate the correlation between noise in the work environment and auditory and extra-auditory symptoms referred by university professors. Methods: Eighty five professors answered a questionnaire about identification, functional status, and health. The relationship between occupational noise and auditory and extra-auditory symptoms was investigated. Statistical analysis considere...

abstract meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal melanocytes. the locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. the manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that causes ...

The number of persons with hearing and vision loss is on the rise as lifespans increase. Vision plays an important role in communication, especially in the presence of background noise or for persons with hearing loss. However, persons with vision loss cannot make use of this extra modality to overcome their hearing deficits. We propose automatically utilizing some visual information in hearing...

OBJECTIVES To determine the carrier rate of the GJB2 mutation c.35delG and c.101T>C in a UK population study; to determine whether carriers of the mutation had worse hearing or otoacoustic emissions compared to non-carriers. DESIGN Prospective cohort study. SETTING University of Bristol, UK. PARTICIPANTS Children in the Avon Longitudinal Study of Parents and Children. 9202 were successful...

noise induced hearing loss (nihl) is one of the most important occupational disease worldwide. nihl has been found potentiate by simultaneous carbon monoxide (co) exposure. free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the co hypoxia. this study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

PURPOSE To document the epidemiological characteristics of a group of children who are hard of hearing, identify individual predictor variables for timely follow-up after a failed newborn hearing screening, and identify barriers to follow-up encountered by families. METHOD The authors used an accelerated longitudinal design to investigate outcomes for children who are hard of hearing in a lar...

BACKGROUND Anecdotal evidence suggests that hearing loss interferes with the enjoyment of music, although it is not known how widespread this problem currently is. PURPOSE To estimate the prevalence of music-listening difficulties among a group of elderly hearing aid wearers. RESEARCH DESIGN Interview. Telephone interviews were conducted with patients who wore hearing aids. Questions regard...

Laurence-Moon Biedl (LMB) syndrome is an autosomal recessive genetic disorder, characterized by structural and functional abnormalities of organs [1]. This syndrome was first described by Laurence and Moon in 1866 [2]. This syndrome is also called Bardet-Biedl syndrome (BBS) as Bardet and Biedl added additional polydactyly feature [3]. The estimated incidence is 1:160,000 in northern European p...

Using three-dimensional PET, the cortical areas activated by bone-conducted ultrasound were measured from five profoundly deaf subjects and compared with the cortical areas of normal-hearing subjects activated by stimuli through bone-conducted ultrasonic, air-conducted, bone-conducted, and vibro-tactile hearing aids. All of the hearing aids, including the ultrasonic hearing aid, consistently ac...
