introduction: it has been shown that low levels of pigmentation increase susceptibility to noise-induced hearing loss in humans. for this reason, white populations develop more pronounced noise- induced hearing loss in comparison to black populations. similarly, blue-eyed individuals exhibit greater temporary threshold shift than brown-eyed subjects; still, no strong correlation has been verifi...
Any type of hearing loss can create imperfect development of educational skills in primary school children. In this descriptive study different types of hearing loss in 22152 six years old preschool children of Hamadan province were screened by means of ...
Objectives: Hearing loss is a major public health problem and has higher prevalence in elderly persons. Present study was conducted with the aim of characterizing age-related changes on audiometric thresholds and word discrimination ability of people with age range of 30 to 100 years. Methods & Materials: Hundred ninty persons (male 53.68% and female 46.32%) in seven aged decades were studie...
hearing loss (hl) is the most common sensory defect. various genetic as well as environmental factors have been shown to contribute in it. more than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (arnshl). here, we report a 6-year old female patient with bilateral pre-lingual hl in whom a mutation has been identified in triobp gene (c.6362c>t, s2121l). in s...
abstract introduction: conductive hearing loss attenuates and delays sound transmission in the middle ear. it can make variety of central auditory processing disorders; that persists even after resolve of peripheral auditory system problems. one of the aspects of central auditory processing is the temporal processing, which is important for understanding speech, including temporal resolution,...
Introduction: Hearing is essential for humans to communicate with one another. Early diagnosis of hearing loss and intervention in neonates and infants can reduce developmental problems. The aim of the present study was to assess the prevalence of hearing impairment in newborns admitted to a neonatal intensive care unit (NICU) and analyze the associated risk factors. Materials and Methods:...
conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...
background: major beta thalassemia is the most common inherited anemia with high prevalence in iran and hearing loss is one of its side effects. the present study aimed to determine the hearing status of patients with major thalassemia and its relationship with serum ferritin level, period of blood transfusion and dessfroxamin administration. methods: this descriptive-analytic study was perform...
Introduction: Noise-induced hearing loss (NIHL) is a major problem in industrialized and developing countries. Trend of industrialization and lack of proper protective equipment lead to an increased frequency of noise-related disorders especially NIHL. This study was conducted to investigate noise pollution and the frequency of NIHL in workers of one of the ceramic industries. Materials and ...
Introduction: The prevalence of hearing loss in neonates is 2-5 out of every 1,000 live births. Global Health Committee, American Academy of Otolaryngology, and American Academy of Pediatrics have recommended that hearing loss in infants be identified, and treated when possible, prior to 6 months of age. This study was designed with the aim to screen the hearing of neonates in Mashhad, Iran. Me...
