  1. 1. Hearing problems in the elderly. Outsider and insider perspectives of presbyacusis

    Detta är en avhandling från Göteborg

    Författare :Ann-Kristin Karlsson Espmark; Göteborgs universitet.; Gothenburg University.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aged; Presbyacusis; Tinnitus; Epidemiology; ICF; Aural rehabilitation; Hearing aid; Pure-tone audiometry; Questionnaire; Psychosocial Factors; Phenomenography; Audiological rehabilitation.;

    Sammanfattning : What insight can be gained from an epidemiological perspective into factors affecting elderly people with hearing difficulties both individually and in relation to their surroundings? How is hearing impairment perceived by the elderly? How great is the need for audiological rehabilitation for elderly people with hearing impairments?Study I is a cross-sectional study within the framework of the age study H70 where a comparison was made between a) tone audiometry and self-assessments of hearing, b) tone audiometry and the prescription of hearing aids and c) self- assessments of hearing and the prescription of hearing aids. Three age cohorts were studied: 1) year of birth 1901-1902 (n=210: 133 f and 77 m), 2) year of birth 1915-16 (n=168: 94 f and 74 m) and 3) year of birth 1922-23 (n=237: 129 f and 108 m). LÄS MER

  2. 2. Ear and hearing problems in Turner syndrome

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Clinical Neuroscience

    Författare :Annika Elmqvist Stenberg; Karolinska Institutet.; Karolinska Institutet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Turner syndrome; tympanic membrane pathology; hearing loss; otitis media; estrogen receptors; presbyacusis; immunology; mouse; rat; human; cochlea; psychosocial; audiometric testing.;

    Sammanfattning : Turner Syndrome is a common chromosomal disorder and affects approximately one in every 2000 newborn girl. The syndrome is defined as a total (45,X) or partial loss of the second sex chromosome in combination with the typical characteristic features, which are short stature (less than 150 cm), absent estrogen production due to ovarian dysgenesis, with failure to enter puberty spontaneously and infertility.

  3. 3. Effects of Specific Cochlear Pathologies on the Auditory Functions Modelling, Simulations and Clinical Implications

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Amin G. Saremi; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Auditory modeling; cochlear mechanics; sensorineural hearing impairment; age-related hearing loss; noise-induced hearing loss; inner ear pathologies;

    Sammanfattning : A hearing impairment is primarily diagnosed by measuring the hearing thresholds at a range of auditory frequencies (air-conduction audiometry). Although this clinical procedure is simple, affordable, reliable and fast, it does not offer differential information about origins of the hearing impairment. LÄS MER

  4. 4. Hearing in increasing age. Epidemiological and psychoacoustic aspects

    Detta är en avhandling från Göteborg

    Författare :Radoslava Jönsson; Göteborgs universitet.; Gothenburg University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aged; Aged; 80 and over; Audiometry; Demography; Ear; Epidemiology; Hearing; Presbycusis; Psychoacoustics; Questionnaires; Socioeconomic Factors; Sound Localization;

    Sammanfattning : Presbyacusis, age-related hearing decline, is the most common cause of hearing impairment in the more developed countries. Planning of health services for the hearing impaired requires knowledge of hearing in increasing age and in demographic changes. LÄS MER

  5. 5. Calcium binding protein immunoreactivity in the central auditory system and correlations with the auditory periphery : The effects of noise and aging in mice

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Författare :Esma Idrizbegovic; Karolinska Institutet.; Karolinska Institutet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Auditory; hearing loss; central auditory system; stereology; plasticity;

    Sammanfattning : This study has examined how calcium binding protein immunoreactivity is modulated in the cochlear nucleus and the inferior colliculus after noise exposure and during aging in mice. The effect of noise exposure on calbindin-D28k (calbindin) and parvalbumin immunoreactivity in the dorsal and posteroventral cochlear nucleus (DCN and PVCN) and inferior colliculus (IC) was studied in CBA/CBA mice by using two-dimensional quantification.
