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. 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.

6. 4. Aspects of the inflammatory response and formation of polys in the nasal and sinus mucosa

   Author : Tomas Norlander; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Experimental sinusitis was induced in rabbits by ostial occlusion, with or without subsequent inoculation of Streptococcus pneumoniae, Staphylococcus aureus or Bacteroides fragilis The general inflammatory response, including goblet cell differentiation and polyp formation, was morphologically investigated. Polyps were experimentally induced by a combining mechanical trauma the mucosa with infection or by injection of agarose or N-formyl-methionyl-leucyl-phenylalanine (FMLP) into the maxillary sinus.

7. 5. On factors influencing the outcome of various methods using endosseous implants for reconstruction of the atrophic edentulous and partially dentate maxilla

   Author : Jonas Becktor; Göteborgs universitet; []
   Keywords : dental implants; grafted bone; maxilla; clinical follow-up; zygomatic implants;

   Abstract : Surgical reconstruction of the severely resorbed edentulous maxilla often requires a combination of bone grafts and dental implants. Different methods have been used during the years where donor site, type of bone graft, healing period, timing of implant placement and implant surface have varied. READ MORE
