patients and methods in this cross-sectional study, 791 infants were recruited via non-random sampling. demographic and clinical characteristics of the subjects were gathered, and the automated auditory brainstem response (aabr) test was performed upon admission. afterwards, the subjects were followed-up and re-assessed, using the aabr test. for infants with abnormal aabr results, the auditory ...

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...

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...

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: th...

abstract introduction: omega 3 fatty acid especially in the form of fish oil, has structural and biological role in the body's various systems especially nervous system. numerous studies have tried to research about it. auditory is one of the affected systems. omega 3 deficiency can have devastating effects on the nervous system and auditory. this study aimed to evaluate neural conduction ...

The efficacy of utilizing an automated algorithm to identify auditory brainstem responses (ABR) was studied. A microcomputer-based threshold-seeking algorithm utilizing click-evoked ABR was developed to determine evoked-response thresholds for automated hearing screening. The software consists of an evoked-response recognizer unit, which determines the presence or absence of a response, and a t...
