Persistent pain is reported to be a frequent complication from surgery. Among the proposed risk factors are perioperative nerve injury and individual differences in pain sensitivity.
The 6th Tromsø Study, a cross-sectional survey and medical examination, provided questionnaire data on persistent pain in general and persistent pain following surgery in particular. Participants performed tests of sensitivity to experimental pain stimuli. A sample of participants who had performed surgery 3-36 months before the survey, were re-assessed with questionnaires and quantitative assessments of sensory function 15-32 months after Tromsø 6.
In accordance with previous research, we found that persistent pain after surgery was common. Moderate or severe pain in the area of surgery 3-36 months after the procedure was reported by
18.3 %. Most cases were coexistent with other chronic pain. Only in a small minority of cases did the patients themselves attribute persistent pain to surgery alone.
In a general surgical sample, we could not identify specific associations between persistent post-surgical pain and sensitivity to experimental pain stimuli when comorbid pain was adjusted for.
Persistent post-surgical pain was strongly associated with self-reported sensory disturbances, indicating possible nerve injury as a contributing factor. Sensory aberrations were confirmed with sensory testing in a majority of individuals with persistent pain in the surgical area. However, nerve injury does not appear sufficient for development of such pain, as signs of nerve injury, confirmed with quantitative sensory testing, were just as common among individuals without persistent post-surgical pain.

The Temporomandibular Joint in Juvenile Idiopathic Arthritis, focusing on Quality of Life, Oral Microbiome and Intervention
Frid, Paula (Doctoral thesis; Doktorgradsavhandling, 2020-10-02)The temporomandibular joint (TMJ) is commonly involved in juvenile idiopathic arthritis (JIA), and may lead to impaired mouth opening, pain and facial growth disturbances. Asymptomatic TMJ arthritis may be diagnosed late in the disease course, thus management is challenging. The overall objectives of this thesis were to provide new knowledge on quality of life (QoL), the oral microbiome and interventions ... -
Prognostic Impacts of Angiopoietins in NSCLC Tumor Cells and Stroma : VEGF-A Impact Is Strongly Associated with Ang-2
Andersen, Sigve; Dønnem, Tom; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Stenvold, Helge; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Angiopoietins and their receptor Tie-2 are, in concert with VEGF-A, key mediators in angiogenesis. This study evaluates the prognostic impact of all known human angiopoietins (Ang-1, Ang-2 and Ang-4) and their receptor Tie-2, as well as their relation to the prognostic expression of VEGF-A. 335 unselected stage I-IIIA NSCLC-patients were included and tissue samples of respective tumor cells and ... -
Humant papillomavirus : en litteraturstudie om HPV, dets relasjon til cancer og tiltak mot videre spredning av virus
Gabrielsen, Endre (Master thesis; Mastergradsoppgave, 2012-06-01)I 1983 oppdaget zur Hausen sammenhengen mellom Humant Papillomavirus (HPV) og livmorhalskreft. På denne tiden visste man ikke at det var HPV som var årsaken til at Helaceller kunne leve in vitro. Ny forskning relaterer HPV til en rekke andre cancertyper. En stor andel anal-, oropharyngeal-, penis-, vaginal-, og vulvacancer skyldes HPV. Det er også påvist HPV i tumorvev fra øsofagus, larynx, lunge, ...
