OBJECTIVE: The aim of the study is to assess the audiological and surgical outcome after cochlear implantation in children with inner ear malformation and to compare them with a group of congenitally deaf children implantees without inner ear malformation. INTRODUCTION: Children with profound sensorineural deafness with malformations of the inner ear represent a challenge, accounting to 5-15% of congenital sensorineural deafness. These cases were originally regarded as a contraindication for cochlear implant surgery...

Attention-deficit/hyperactivity disorder (ADHD) and anxiety-related disorders occur at rates 2-3 times higher in deaf compared with hearing children. Potential explanations for these elevated rates and the heterogeneity of behavioral disorders associated with deafness have usually focused on socio-environmental rather than biological effects. Children with the 22q11.2 deletion or duplication syndromes often display hearing loss and behavioral disorders including ADHD and anxiety-related disorders. Here, we show that mouse mutants with either a gain- or loss-of-function of the T-Box transcription factor gene, Tbx1, which lies within the 22q11...

Forty-one children with severe-profound prelingual hearing loss were assessed on single word reading, reading comprehension, English vocabulary, phonological awareness and speechreading at three time points, 1 year apart (T1-T3). Their progress was compared with that of a group of hearing children of similar nonverbal IQ, initially reading at the same level. Single word reading improved at each assessment point for the deaf children but there was no growth in reading comprehension from T2 to T3. There were no differences between children with cochlear implants and those with hearing aids on either reading measure but orally educated children had higher scores than children who signed in the classroom...

BACKGROUND: Simultaneous bilateral cochlear implantation promotes symmetric development of bilateral auditory pathways but binaural hearing remains abnormal. To evaluate whether bilateral cortical processing remains impaired in such children, cortical activity to unilateral and bilateral stimuli was assessed in a unique cohort of 16 children who received bilateral cochlear implants (CIs) simultaneously at 1.97 ± 0.86 years of age and had ~4 years of CI experience, providing the first opportunity to assess electrically driven cortical development in the absence of reorganized asymmetries from sequential implantation...

Children naturally acquire a language in social contexts where they interact with their caregivers. Indeed, research shows that social interaction facilitates lexical and phonological development at the early stages of child language acquisition. It is not clear, however, whether the relationship between social interaction and learning applies to adult second language acquisition of syntactic rules. Does learning second language syntactic rules through social interactions with a native speaker or without such interactions impact behavior and the brain? The current study aims to answer this question...

BACKGROUND: The occurrence of meningitis in children >5 years old may be associated with specific predisposing factors that can be anatomic, such as cerebrospinal fluid fistula or breach, or related to genetic susceptibility or N inborn or acquired immunologic defect. This study aimed to assess the anatomical and immunologic risk factors in children >5 years old with pneumococcal meningitis and prospectively enrolled in the French national meningitis network. METHODS: We analyzed all data for children who were 5-15 years old with a diagnosis of pneumococcal meningitis between 2001 and 2013...

OBJECTIVES: This study aimed to examine whether (a) exposure to universal newborn hearing screening (UNHS) and b) early confirmation of hearing loss were associated with benefits to expressive and receptive language outcomes in the teenage years for a cohort of spoken language users. It also aimed to determine whether either of these two variables was associated with benefits to relative language gain from middle childhood to adolescence within this cohort. DESIGN: The participants were drawn from a prospective cohort study of a population sample of children with bilateral permanent childhood hearing loss, who varied in their exposure to UNHS and who had previously had their language skills assessed at 6-10 years...

Introduction Usher syndrome (US) is an autosomal recessive disorder characterized by hearing loss and progressive visual impairment. Some deaf Usher syndrome patients learn to communicate using sign language. During adolescence, as they start losing vision, they are usually referred to cochlear implantation as a salvage for their new condition. Is a late implantation beneficial to these children? Objective The objective of this study is to describe the outcomes of US patients who received cochlear implants at a later age...

The number of deaf children has dramatically increased in the past few decades. These children present to the pediatric dentist a unique set of challenges mostly pertaining to the establishment of communication with them. There have been very few attempts in the past to break down these challenges and formulate a strategy on how to manage them effectively. This is a case report of a child who was successfully managed using two different modes of communication. Finally, the advantages and disadvantages are mentioned, and a common strategy incorporating the positives of both the methods has been devised...

CONCLUSIONS: The present study revealed that various etiologies are involved in single-sided deafness (SSD), and that the cause of SSD and asymmetrical hearing loss (AHL) differed greatly between congenital/early-onset cases and adult cases. Clarification of the etiology is the first step toward providing appropriate intervention. OBJECTIVES: The study aimed to clarify the etiology of SSD and AHL patients. METHODS: The etiology of a total of 527 SSD or AHL patients who visited Shinshu University Hospital between 2006 and 2016 were analyzed by imaging as well as serological tests for mumps virus, and CMV DNA testing...

It is not clear how audio-visual temporal perception develops in children with restored hearing. In this study we measured temporal discrimination thresholds with an audio-visual temporal bisection task in 9 deaf children with restored audition, and 22 typically hearing children. In typically hearing children, audition was more precise than vision, with no gain in multisensory conditions (as previously reported in Gori et al. (2012b)). However, deaf children with restored audition showed similar thresholds for audio and visual thresholds and some evidence of gain in audio-visual temporal multisensory conditions...

OBJECTIVE: In Colombia there are three main treatment approaches for bilateral profound sensorineural hearing loss, also known as profound deafness (PD): cochlear implants (CI), hearing aids (HA), and no treatment (NT). The objective of this study is to determine the optimal treatment approach for PD in terms of productivity and cost-effectiveness. STUDY DESIGN: Hearing levels and SES data were obtained from audiometric tests conducted on 100 patients with CI. For each treatment approach, productivity and cost-effectiveness assessments were estimated using influence diagrams and Monte Carlo simulations...

BACKGROUND: A significant percentage of children with cleft palate suffer from otitis media with effusion and its consequences, such as deafness, chronic adhesive otitis and cholesteatoma. This study aimed to determine whether these effects can be minimised by selecting pharyngofixation as the surgical technique for cleft palate correction. METHODS: A retrospective study was performed of 155 patients (308 ears) who underwent surgery from age 5 months to 8 years and were followed up for 36-84 months...

Hereditary hearing impairment (HI) caused by recessive GJB2 mutations is a frequent sensory disorder. The results of the molecular-based studies of HI are widely used in various genetic test systems. However, the ethical aspects are less described than the genetic aspects. The concerns expressed by individuals from groups with genetic risks must be included in the counseling of patients and their families. For evaluation of subjective opinions of hearing parents about the presumed causes of HI of their children, we analyze the cohort of parents having children with confirmed hereditary HI caused by biallelic recessive GJB2 mutations (in a homozygous or a compound heterozygous state)...

Steel syndrome is an autosomal recessive disease characterized by skeletal abnormalities and dysmorphic features. The first mutation associated with this syndrome was reported in Puerto Rican children. In this study, we identified a novel homozygous splice site variant in COL27A1 (c.3556-2A>G) in a consanguineous Emirati family with a child affected by Steel syndrome. In addition, the affected child had severe non-progressive sensorineural hearing loss not reported previously. The variant segregated in the family in an autosomal recessive manner and we show that the variant alters mRNA splicing...
