  1. 1. 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. 2. Mapping viruses in non-malignant tonsils, nasal polyps, sinonasal inverted papilloma and laryngeal cancer

    Författare :Alexandra Schindele; Katarina Olofsson; Karin Nylander; Annika Allard; Lalle Hammarstedt Nordenvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human papilloma virus; Epstein-Barr virus; Human cytomegalovirus; Human adenovirus; p16 tumor suppressor protein; Non-malignant tonsillar disease; Chronic rhino sinusitis with nasal polyps; sinonasal inverted papilloma; laryngeal cancer; EBER-ISH; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Background: The upper respiratory tract is exposed to viruses, which can lead to infection and cancer development. We chose to study common and/or chronic diseases along with common and cancer related viruses in the upper airway. LÄS MER

  4. 3. Clinical, immunological and olfactory aspects of sinusitis and nasal polyposis : with special reference to patients with cystic fibrosis

    Författare :Gert Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nasal polyposis; sinusitis; cystic fibrosis; allergy; bacteria; in-patient; interleukin-8; muramidase; nasal lavage fluid; polymerase chain reaction; Pseudomonas aeruginosa; smell; olfaction; anosmia; hyposmia; olfactory threshold test; identification smell test; germ-free animal; T-cell receptor; normal microbiota.;

    Sammanfattning : The otorhinolaryngological approach to the problem concerning rhinosinusitis and nasal polyposis in the recessive genetic disorder of cystic fibrosis (CF) has been developed based on data from international studies. Opinions differ on how to treat the otolaryngological manifestations of CF (sinusitis, nasal polyps and hyposmia). LÄS MER

  5. 4. Mucosal regeneration following sinus surgery : an experimental study and clinical study

    Författare :Karin Forsgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :chronic sinusitis; histopathology; Caldwell-Luc operation; sinus surgery; rabbit; regeneration; sinus mucosa; experimental sinusitis; microcirculation; blood flow; vasoreactivity; nerve regeneration; sympathetic; neuropeptide Y; tyrosine hydroxylase; immunocytochemistry;

    Sammanfattning : The investigations described in this thesis concerned functional and structural aspects of the regenerated sinus mucosa following sinus surgery. In a biopsy material collected pre- and postoperatively from patients with chronic maxillary sinusitis, randomized for treatment with either Functional Endoscopic Sinus Surgery (FESS) or the Caldwell-Luc procedure (CL), histological parameters were evaluated semi-quantitatively and correlated to endoscopic findings and patients' symptoms.

  7. 5. Airborne nitric oxide : inflammatory marker and aerocrine messenger in man

    Författare :Jon Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ARDS; asthma; cystic fibrosis; cystitis; exhaled air; inflammatory bowel disease; inhaled nitric oxide; Kartagener s syndrome; nitric oxide synthase; sinusitis; ;

    Sammanfattning : We have used a chemiluminescence technique to measure gaseous nitric oxide (NO) directly in hollow organs of humans. NO production was studied in the airways of healthy controls and patients with chronic inflammatory airway disease, in the stomach of healthy subjects, in the colon of patients with inflammatory bowel disease, and in the urinary bladder of patients with cystitis.
