  1. 21. Recurrent Streptococcal Pharyngotonsillitis Studies on etiology and treatment

    Författare :Arne Orrling; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; Otorinolaryngologi; Infektioner; Otorhinolaryngology; Infections; Clindamycin.; Penicillin tolerance; Tonsillar surface fluid; treatment failure; Group A streptococci; hörsel- och talorganen; audiologi; audiology; Recurrent streptococcal pharyngotonsillitis;

    Sammanfattning : In acute pharyngotonsillitis group A streptococci (GAS) is the etiological agent in 30-50% of cases. Phenoxymethylpenicillin (pcV) is the drug of choice in Sweden. However, the failure rate is as high as 5-25% and further pcV treatment is followed by still higher failure rates. The background of failures remains largely elusive. LÄS MER

  2. 22. Ventilation of the Paranasal Sinuses. A study using the 133-Xenon Washout Technique

    Författare :Bo Paulsson; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 23. Long-term follow-up after otitis media in childhood

    Författare :Marie Ryding; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; audiology; hörsel- och talorganen; audiologi; auditive system and speech; Otorinolaryngologi; tympanic membrane pathology.; otitis media with effusion; hearing loss; follow-up; acute otitis media; Eustachian tube;

    Sammanfattning : Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. LÄS MER

  4. 24. 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

  5. 25. 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
