The Outcomes of Cochlear Implantation in Patients with Solid Organ Transplant.

Introduction: As far as it is known, long-lasting immunosuppressive therapy might put patients with solid organ transplantation (SOT) at increased risk for severe to profound sensorineural hearing loss, eventually leading to cochlear implantation (C.I). So, the main aim of the present study is to evaluate their auditory perception performance after cochlear implantation.

Evaluating the Relation Between Mothers' Depression Level and Their Cochlear Implanted Children's Social Performance.

Since the child's sensorineural hearing loss and its negative consequences, including weak social skills, is one of the most challenging problems for parents and other family members, the main aim of the present study is to investigate if there is any probable relation between the cochlear implanted children's social performance and their mothers' depression level,in this cross-sectional observational analytic research, we implemented the Beck Depression Inventory version- II to evaluate the level of depression in 29 mothers of cochlear implanted children. Also, we assessed their children's social abilities through the Vineland Adaptive Behavior Scale. Finally, the analysis of variance (ANOVA) was carried out to find any probable relation between the mothers' depression level and their children's social performance.

Based on this, the main focus of the present study was to investigate the cognitive performance of cochlear-implanted children after a cognition-based language intervention program.

Methods: In this experimental study, 60 cochlear-implanted children were selected and randomly allocated into case and control groups.

Identification of homozygous mutations for hearing loss.

Background: Hearing loss is the most common sensory disorder worldwide, affecting about 1 out of every 1000 newborns. The disease has major genetic components, and can be inherited as a single gene disorder either in autosomal dominant or recessive fashions. Due to the high rate of consanguineous unions, Iran has one of the highest prevalence of autosomal recessive nonsyndromic deafness (ARNSD) in the world.

Bipolar loop device versus bipolar diathermy for tonsillectomy: A pilot randomized controlled trial.

Objective: Tonsillectomy is one of the most common surgeries performed in the pediatric population.

Hearing loss is the most prevalent sensorineural disorder which can be caused by genetic factors in more than half of the cases. GJB2 mutations with the frequency of 18.7% are the most common cause of autosomal recessive non-syndromic hearing loss (ARNSHL) in the Iranian population.

Correlation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants.

Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance.

The effectiveness of a specifically-designed language intervention protocol on the cochlear implanted children's communication development.

Objective: Although various studies have depicted the importance of language intervention programs in facilitating language acquisition in cochlear implanted children, to this date rarely has a specific language intervention approach been recommended as better than the other and no best practice has been introduced in terms of language acquisition outcomes. Thus, the therapists remain uncertain as to which approach to follow and how to apply evidence to practice. Hence, the main goal of this study was to take a step in this regard by comparing the communication development of pediatric cochlear implant users who enrolled in two different language intervention approaches: the routine auditory-verbal approach, and the routine auditory-verbal approach plus a new intervention protocol specifically designed to enhance receptive vocabulary development in cochlear implanted children.

The Development of an Interventional Package on "Receptive Vocabulary" For Cochlear Implanted Children.

Objectives: Considering the shortage of language intervention protocols which specifically concentrate on cochlear implanted children and considering the importance of timely language intervention in this group of children, the aim of the present study was to develop an interventional package on "receptive vocabulary" for cochlear implanted children.

Materials & Methods: By reviewing the literature related to language acquisition theories in normal and language disordered children, as well as literature on production of intervention protocols, especially those for language impaired children, and also considering the normal process of language and speech development in normal children, the first draft of the intervention protocol was prepared. Then, the face and content validity of the intervention protocol was assessed by a Delphi team through three rounds and finally approved.

Comparison of Social Interaction between Cochlear-Implanted Children with Normal Intelligence Undergoing Auditory Verbal Therapy and Normal-Hearing Children: A Pilot Study.

Objective: A cochlear implant is a device that helps hearing-impaired children by transmitting sound signals to the brain and helping them improve their speech, language, and social interaction. Although various studies have investigated the different aspects of speech perception and language acquisition in cochlear-implanted children, little is known about their social skills, particularly Persian-speaking cochlear-implanted children. Considering the growing number of cochlear implants being performed in Iran and the increasing importance of developing near-normal social skills as one of the ultimate goals of cochlear implantation, this study was performed to compare the social interaction between Iranian cochlear-implanted children who have undergone rehabilitation (auditory verbal therapy) after surgery and normal-hearing children.
