  2. 16. Assessment of increased upper airway resistance in snorers. Methodological and diagnostic considerations

    Author : Sören Berg; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arousals.; pharyngeal pressure; intrathoracic pressure; hypopnea; respiratory ventilation; oxygenation; Non apneic snorers; upper airway obstruction; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : Sleep-related partial upper airway obstruction may cause increased morbidity and mortality, but diagnosis and treatment of patients is varying and inconsistent. The present studies were aimed to evaluate presently applied indirect methods for assessing respiratory ventilation and to investigate the value and accuracy in estimating upper airway resistance during sleep by measuring intrathoracic pressure variation with a microchip catheter in the esophagus.

  4. 17. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology

    Author : Konrad Konradsson; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; audiology; Pressure; Audiometry; Cats; Animal; Cochlea; Cochlear aqueduct; Ear; Eustachian tube; Hearing; Otorinolaryngologi; Human; Labyrinth; Otorhinolaryngology; Meniere s disease; audiologi; hörsel- och talorganen;

    Abstract : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. READ MORE

  5. 18. Toll-like Receptors in Allergic Rhinitis

    Author : Mattias Fransson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; poly I:C ; uteroglobin; Toll-like receptors; Medicine human and vertebrates ; Medicin människa och djur ; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; innate immunity; LPS; allergic rhinitis; bone marrow;

    Abstract : Allergic rhinitis is an inflammatory disorder with the characteristic symptoms itching, sneezing, secretion and blockage upon allergen contact. In addition to the local inflammation in the nose, there is a systemic component that influences peripheral blood, bone marrow and lungs. READ MORE

  6. 19. Noise exposure, hearing protection and hearing loss. A long-term study at an automobile sheet-metal pressing plant

    Author : Pawel Brühl; Lund näs- och halssjukdomar Öron-; []

    Abstract : The design and implementation of a hearing conservation programme in a heavy industry with high noise levels is described. Action was taken on several points, including noise measurements, noise reduction, education on hearing protector use, and audiometric monitoring. READ MORE

  7. 20. Ventilation of the Paranasal Sinuses. A study using the 133-Xenon Washout Technique

    Author : Bo Paulsson; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; single photon emission computed tomography; paranasal sinuses; ventilation; 133-xenon; chronic sinusitis; nose-sinus model; endoscopic sinus surgery; oxymetazoline; Otorhinolaryngology; Otorinolaryngologi; audiologi; hörsel- och talorganen; audiology;

    Abstract : A noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. READ MORE
