The purpose of this paper is to document the early Spanish speech development of a toddler, K, whose cochlear implant was activated at age 20 months. The contribution of K's developmental pattern to research is unique in that Spanish is the sole language of the home, as well as being the language of intervention up to 16 months postimplant (3…

Between 2000 and 2006, the University Clinic for Ear Nose and Throat and Communication Disorders in Mainz, Germany, performed 41 bilateral cochlear implantations in children. This article addresses some of the factors to be considered in a decision to bilaterally implant a child, including the age of the child at the first implant, the length of…

The importance of early intervention for children with hearing loss has been demonstrated persuasively in areas including speech perception and production and spoken language. The present research shows that feelings of loneliness, a significant emotional outcome, are affected by the age at which children receive intervention with cochlear…

Infant hearing screening is emerging rapidly as a silent global revolution for the early detection of children with congenital or early onset hearing loss to ensure timely enrollment in family-oriented intervention programs for the development of spoken language. This article examines the overriding and interrelated scientific, ethical and…

At age 3, children with hearing loss transition from Part C early intervention to Part B public school services. These children represent a heterogeneous population when considering factors such as communication approaches; speech, language, auditory and cognitive skills; social-emotional and motor development; parental involvement; hearing…

Over the past two decades, considerable progress has been made in understanding the mechanisms underlying aminoglycoside ototoxicity. Aminoglycoside damage progresses from cochlear base to apex and from outer to inner hair cells. Aminoglycoside antibiotics enter hair cells at the apical pole and are taken up into lysosomes and mitochondria.…

To evaluate the relative contributions of auditory perceptual access and production system characteristics to early vocalization patterns, three infants identified with hearing loss at birth were followed longitudinally for 11 months beginning at 4 to 6 months hearing age (i.e. time of post-hearing instrument fitting). The infant with…

An experimental procedure was developed to investigate word-learning skills of children who use cochlear implants (CIs). Using interactive play scenarios, 2- to 5-year olds were presented with sets of objects (Beanie Baby stuffed animals) and words for their names that corresponded to salient perceptual attributes (e.g., "horns" for a goat). Their…

The purpose of this study was to validate competencies necessary for effective work in early intervention with infants and toddlers who are deaf or hard of hearing. These were developed and implemented in the context of a graduate professional preparation program in early intervention in deaf education. This interdisciplinary, family-centered…

With the advent of newborn hearing screenings, infants with hearing loss are identified earlier than ever before. Each state is responsible for providing trained personnel and delivery of early intervention services to families with newly identified infants and toddlers who are deaf or hard of hearing. Consequently, the role of each state's Part C…

To facilitate evaluations of cochlear implant candidates and to promote (re)habilitation efficacy and collaboration with families, this study examined the expectations of 35 mothers with typical hearing and their beliefs and difficulties related to their child's hearing loss and current or future cochlear implantation. Questionnaires measured…

The availability of cochlear implants in younger children has provided the opportunity to evaluate the relative impact of the production system, or the sounds young children can say, and the auditory system, or the sounds children can hear, on early vocal communication. Limited access to the acoustic properties of speech results in differences in…

This study was a longitudinal examination (21 month follow-up) of language development in a pair of fraternal twins. One twin received a cochlear implant at age 20 months secondary to sensorineural hearing loss. The other twin had normal hearing. Data were obtained every 6 months following her initial cochlear implant stimulation. Both twins…

Gentamicin is an aminoglycoside antibiotic that has been a mainstay in pediatric care for decades. Although new antibiotics are constantly under development, gentamicin continues to play an important role in clinical medicine. Although this may be surprising in the context of evidence of an association with hearing loss, both on a toxicity and a…

The mitochondrial DNA (mtDNA) 12S rRNA is a hot spot for mutations associated with both aminoglycoside-induced and nonsyndromic hearing loss. Of those, the homoplasmic A1555G and C1494T mutations at a highly conserved decoding region of the 12S rRNA have been associated with hearing loss. These two mutations account for a significant number of…
