Introduction: Conductive hearing loss due to chronic otitis media (COM) can be treated by surgery. COM, however, may be associated with functional damage to the inner ear. Sensorineural hearing loss (SNHL) due to COM has been found to be significant by some authors, whereas it has been considered negligible by others. The present study aimed to answer the question Does COM cause SNHL ? Methods...
UNLABELLED Cisplatin is a common and effective chemotherapeutic agent, yet it often causes permanent hearing loss as a result of sensory hair cell death. The causes of sensitivity to DNA-damaging agents in nondividing cell populations, such as cochlear hair and supporting cells, are poorly understood, as are the specific DNA repair pathways that protect these cells. Nucleotide excision repair (...
this study examined hearing loss prevalence and hearing aid usage rates among korean elders by comparing the differences between those with and without hearing loss, and between those who used and did not use hearing aids.this study was based on data collected during the korean national health and nutrition examination survey v (2010-2012). the study sample consisted of 5,447 koreans aged ≥60 y...
In this study, a five-generation Chinese family (family F013) with progressive autosomal dominant hearing loss was mapped to a critical region spanning 28.54 Mb on chromosome 9q31.3-q34.3 by linkage analysis, which was a novel DFNA locus, assigned as DFNA56. In this interval, there were 398 annotated genes. Then, whole exome sequencing was applied in three patients and one normal individual fro...
BACKGROUND A considerable amount of research has been published about genetic hearing impairment. Fifty to sixty percent of hearing loss is thought to have a genetic cause. Genes may also play a significant role in acquired hearing loss due to aging, noise exposure, or ototoxic medications. Between 1995 and 2012, over 100 causative genes have been identified for syndromic and nonsyndromic forms...
Objectives: CSOM is significantly associated with SNHL but mixed demographical associations being reported in literature.To determine the variations (age and gender) of among patients Study design setting: Cross-sectional observational study at Jinnah Postgraduate Medical Center, Karachi, Pakistan. Methodology: Using non-probability convenient sampling, diagnosed within six months between 10-50...
introduction: hearing loss is one of the most disabling impairments. using a hearing aid as an attempt to improve the hearing problem can positively affect the quality of life for these people. this research was aimed to assess satisfaction of hearing impaired patients with their hearing aids regarding the employed technology and style. materials and methods: this descriptive-analytic cross-s...
introduction: hearing loss is the most common sensory defect in humans, affecting approximately 1 in 1000 neonates in which genetic factors are involved in more than 50%. connexin 26 or gjb2 gene mutations are responsible for half of autosomal recessive non-syndromic hearing losses. the purpose of this study was to determine the gjb2 mutations frequency in autosomal recessive non-syndromic deaf...
