  1. 1. Hearing in children with cleft palate

    Författare :Birgitta Tengroth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Objective: The overall aim of this thesis was to collect longitudinal information about hearing thresholds and complications due to otitis media with effusion (OME) in children with cleft palate. Since OME is highly prevalent in children with cleft palate, many authors have hypothesized that the hearing loss associated to OME contributes to the delayed development of early speech and language often seen in these children.

  3. 2. Children with congenital unilateral sensorineural hearing loss : etiology, newborn diagnostics, and hearing aid amplification

    Författare :Marlin Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Congenital unilateral sensorineural hearing loss (uSNHL) comprises about 25% of the sensorineural hearing losses (SNHLs) found through newborn hearing screening (NHS) programs. Even if children with congenital uSNHL struggle in school and everyday listening situations, studies on etiology, hearing aid (HA) outcomes and intervention are few, so it is still unknown when and how intervention is optimally provided.

  4. 3. Hearing Screening of Infants and The Importance of Early Language Acquisition

    Författare :Miriam Magnuson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital hearing impairment. Neonatal hearing screening. Late diagnosis. Parental concern. Otoacoustic emissions. Early language acquisition;

    Sammanfattning : This thesis explores the parental perspective on hearing-screening of children, and the importance of the time of detection of a congenital hearing impairment for the child's development. A qualitative approach based mainly on interviews was employed, and the results were analysed according to three different methods - empirical phenomenology, grounded theory, and case-study. LÄS MER

  5. 4. Signal processing approaches on otoacoustic emissions

    Författare :Jun Cheng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :otoacoustic emissions; signal processing; time-frequency representation; cochlea; outer hair cell; neonatal hearing screening; basilar membrane nonlinearity; bounce phenomenon; spectral estimation; interrelations of OAEs;

    Sammanfattning : The recent achievement on the measurement of otoacoustic emissions (OAEs) is based on a novel technical development of digital signal processing. OAEs measured in the external ear canal are normal by-products of the active process in hearing, which was discovered by Kemp (1978). LÄS MER

  7. 5. Cytomegalovirus and herpes simplex virus infections in the fetus and newborn infant, with regard to neurodevelopmental disabilities

    Författare :Mona-Lisa Engman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The congenital cytomegalovirus infection (CMV) is the most common congenital infection causing childhood morbidity. The majority (85%) of infected infants have no signs of infection in the newborn period, and when sequelae such as a hearing deficit or neurological impairment manifest themselves, the possibility of a CMV infection is easily overlooked.
