  1. 21. Clinical Electrocochleography in Menière´s disease

    Författare :Kornel Sass; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intrathoracic pressure; perilymphatic fistula; pressure exposure; endolymphatic hydrops; Menière´s disease; reproducibility; specificity; sensitivity; rarefaction click; condensation click; electrocochleography; summating potential; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. LÄS MER

  3. 22. Middle Ear Pressure; A New Method for Continuous Direct Measurements

    Författare :Bo Tideholm; allergi och livskvalitet Laryngoesofagologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; man; physiology; sleep; posture; pressure; patulous Eustachian tube; middle ear; Ear; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. LÄS MER

  4. 23. Clinical and Experimental Aspects of Phonetogram Analysis

    Författare :Leif Åkerlund; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; subglottal pressure.; sound pressure level; semitones; phonetogram contours; phonetogram; intensity; Fundamental frequency; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : A phonetogram is a diagram displaying sound pressure levels (SPL) of softest and loudest possible phonation over the entire fundamental frequency range (F0) of a voice. Female singers mean phonetogram had a significantly higher upper contour than female nonsingers. LÄS MER

  5. 24. Prognostic factors in squamous cell carcinoma of the head and neck, with emphasis on 11q13 rearrangements and cyclin D1 overexpression

    Författare :Jan Åkervall; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiologi; Otorinolaryngologi; auditive system and speech; audiology; head and neck; squamous cell carcinoma; genetics; prognosis; CCND1; chromosomes; cyclin D1; chemotherapy; Otorhinolaryngology; gene expression; hörsel- och talorganen;

    Sammanfattning : At present, clinical outcome or response to therapy can not be fully predicted in individual cases of squamous cell carcinoma of the head and neck (SCCHN). The overall aim of the present studies was to investigate potential prognostic factors, more closely related to the malignant progression of a tumor than the established markers, such as the TNM-classification system.
