  2. 1. Ventilator-associated sinusitis : a clinical investigation into the inflammatory response : reactive – infective – infectious?

    Author : Viveka Westergren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : nosocomial sinusitis; infection; inflammation; bacteriology; cytokines; critically ill patients;

    Abstract : Critically ill mechanically ventilated patients regularly have inflammatory reactions in the paranasal sinuses. Infectious sinusitis, which is difficult to diagnose, may occur, mainly in the maxillary sinuses. This study was performed with the object of improving the knowledge of inflammatory and/or infectious disease. READ MORE

  4. 2. 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

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

    Author : Gert Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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.;

    Abstract : 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). READ MORE

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

    Author : Alexandra Schindele; Katarina Olofsson; Karin Nylander; Annika Allard; Lalle Hammarstedt Nordenvall; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Karin Forsgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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;

    Abstract : 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.
