Hereditary deafness has proved to be extremely heterogeneous genetically with more than 40 genes mapped or cloned for non-syndromic dominant deafness and 30 for autosomal recessive non-syndromic deafness. In spite of significant advances in the understanding of the molecular basis of hearing loss, identifying the precise genetic cause in an individual remains difficult. Consequently, it is impo...

Working memory, language, and reading comprehension are strongly associated in children with severe and profound hearing impairment treated by cochlear implants (CI). In this study we explore this relationship in sixteen Swedish children with CI. We found that over 60% of the children with CI performed at the level of their hearing peers in a reading comprehension test. Demographic factors were...

This article describes the hearing impairment (HI) phenotype which segregates in a large multi-generation Swiss-German family with autosomal dominant nonsyndromic HI. The locus segregating within this pedigree is located on chromosome 4q35-qter and is designated as DFNA24. For this pedigree, audiometric data on 25 hearing-impaired family members are available. It was demonstrated that within th...

Objectives: Cognitive emotion regulation plays an important role in the emotional intelligence of students with hearing impairment. The present study was conducted to determine the effect of cognitive emotion regulation on emotional intelligence in students with hearing impairment.  Methods: The present study was a quasi-experimental research with pre-test-post-test and control group design. T...

Congenital cytomegalovirus (CMV) infection is an important public health problem with approximately 7 in 1,000 newborns infected and consequently at risk for hearing impairment. Newborn hearing screening will fail to detect this hearing impairment in approximately half of the cases because late onset hearing loss is frequent. Hearing impairment has profound impact on cognitive and social develo...

Introduction: The present study seeks to describe and analyze the syntactic features of children with severely hearing loss who had access to the hearing aids compared with children with normal hearing, assigning them to the same separate gender classes.   Materials and Methods: In the present study, eight children with severe hearing impairment who used a hearing aid and eight hearing children...

The pure-tone audiogram gives a limited information about the r esidual hearing of hearing-impaired subjects. This i s especially the case when the hearing loss is severe or profound. In these cases often wide variations a r e obtained in results on speech-discrimination tests for the same degree of hearing loss. In some cases it i s likely that the puretone audiogram only shows tactile sensati...

INTRODUCTION Neonatal hypernatremia dehydration (NHD) is a dangerous condition in neonates, which is accompanied by acute complications (renal failure, cerebral edema, and cerebral hemorrhage) and chronic complications (developmental delay). Children begin learning language from birth, and hearing impairment interferes with this process. We assessed the hearing status of infants with hypernatre...

Objectives: The prevalence of consanguineous marriage is about 30 % in Iran and this can increase the probability of incidence of genetic impairments such as hearing impairments. Hearing impairment in comparison with other hereditary disorders is the most incident. The purpose of this survey is to identify the prevalence of consanguinity among the parents of sensoryneural hearing impaired stude...
