objective(s): non-syndromic sensorineural hearing loss (nshl) is a common disorder affecting approximately 1 in 500 newborns. this type of hearing loss is extremely heterogeneous and includes over 100 loci. mutations in the gjb2 gene have been implicated in about half of autosomal recessive nshl (arnshl) cases, making this the most common cause of arnshl. for the latter form of deafness, most f...

objective(s) despite the enormous heterogeneity of genetic hearing loss, most non-syndromic hearing losses are caused by mutations in the gjb2 gene. we aimed to characterize the mutation profiles of 100 iranian deaf patients that were under 10 years old. materials and methods patients were tested with direct sequencing of entire coding region of the gjb2 gene. results eight known mutations plus...

measurement and analysis of noise level in various frequency bands was carried out in a textile factory. it was shown that the noise level in various working places, particularly in the weaving workshop, was quite excessive comparing to the standards and so, it may very likely result in producing hearing loss in the workers. to determine the hearing loss of the workers due to excessive noise, 1...

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:...

introduction:   the daf is a large persian frame drum used as a musical instrument in both popular and classical music which can induce a percussive sound at low frequencies (146–290 hz) with peaks of up to 130 dbspl. the percussive sounds have a power distribution in the region of saccular sensitivity. in view of the saccular stimulation by sound in humans, we decided to use cervical vestibula...

abstract the prevalence of bilateral sudden sensorineural hearing loss (ssnhl) is less than 5% and the etiology of most cases is unknown. due to many structural and functional similarities between the kidney and inner ear, many conditions, diseases, and drugs have both renal and cochlear effects and toxicities. there are several reports of ssnhl in patients with crf, uraemic patient, hemodialys...

objectives: weight loss as a consecution of losing appetite in post-operative patients and those suffering from hiv, cancer, cachexia and inflammatory diseases are the main inducements of morbidity and mortality. there is an increasing demand for more efficacious and endurable appetite stimulating treatment for patients with cachexia. health economics is influenced by the malnutrition which was...

introduction deafness is one of the most important sensory disturbances at birth. hearing loss can affect the development of speaking and learning during life. early diagnosis and intervention improve language outcome. the  current study aimed to determine the frequency of profound congenital hearing loss in healthy newborn infants in fars province. methods in a multicenter prospective study, f...

abstract:background : hyperbilirubinemia is one of the most common cause of congenital sensory neuronal hearing loss. these patients are screened by auditory brainstem response (abr) test at bilirubin levels higher than 1% of gestational weight. aim: to determine whether hyperbilirubinemia less than 1% of gestational weight could induce hearing loss and abnormal auditory brainstem response (abr...
