Congenital human cytomegalovirus (HCMV) occurs in 0.5-1% of live births and approximately 10% of infected infants develop hearing loss. The mechanism(s) of hearing loss remain unknown. We developed a murine model of CMV induced hearing loss in which murine cytomegalovirus (MCMV) infection of newborn mice leads to hematogenous spread of virus to the inner ear, induction of inflammatory responses...
Introduction: Literature regarding the different degrees of hearing loss in patients with Cornelia de Lange syndrome (CDLS) reports that half of the affected patients exhibit severe to profound sensorineural hearing loss. We present the first pre-school child with CDLS who underwent cochlear implantation for congenital profound sensorineural hearing loss. Case Report: A 3-year-old boy with CD...
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...
Degraded sensory experience during critical periods of development can have adverse effects on brain function. In the auditory system, conductive hearing loss associated with childhood ear infections can produce long-lasting deficits in auditory perceptual acuity, much like amblyopia in the visual system. Here we explore the neural mechanisms that may underlie "amblyaudio" by inducing reversibl...
Background and Aims: Sudden sensorineural hearing loss (SSNHL) is a common disorder diagnosed in otologic and audiologic practices. Its accompanying symptoms include tinnitus, dizziness, and permanent hearing loss affecting negatively the life quality of affected patients. Many viruses have been involved in the occurrence of SSNHL especially Herpes simplex virus (HSV) type I and II. This study ...
Introduction: Hearing impairment has a large economic and social burden on societies. Determination of related demographic and audiologic characteristics of deaf patients can help to understand the related factors to hearing impairment and prevent it. In this study we assessed the demographic and audiologic characteristics of deaf patients in a population in the north of Iran. Materials and Met...
Hearing loss is the most widespread sensory disorder, with an incidence of congenital genetic deafness of 1 in 1600 children. For many ethnic populations, the most prevalent form of genetic deafness is caused by recessive mutations in the gene gap junction protein, beta 2, 26 kDa (GJB2), which is also known as connexin 26 (Cx26). Despite this knowledge, existing treatment strategies do not comp...
