    Sammanfattning : Ulcerative colitis is a chronic inflammatory disease that mainly affects the colon and rectum. Onset of disease is most common between the ages of 15-35 years. There is an observed increased risk of colorectal cancer associated with the disease. The risk is often described to be 2% after 10 years, 8% after 20 years and 18% after 30 years disease. LÄS MER

  3. 2. Ulcerative colitis : Imaging of inflammation

    Författare :Sven Almer; Vibeke Binder; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Ulcerative colitis is a chronic inflannnatory disorder of unknown origin engaging the large bowel. Based on the need for accurate assessment of inflammation, three different non-invasive techniques, two leukocyte scintigraphy techniques and one radiological method, were evaluated in the assessment of active inflammation in altogether 131 patients with ulcerative colitis.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ulcerative Colitis; Long-term Function; IPAA; IRA; Neoplasia; Surveillance; Primary Sclerosing Cholangitis; Galectins; Immunohistochemistry;

    Sammanfattning : Background: Ulcerative Colitis (UC) is a chronic inflammatory bowel disease; the etiology is mainly unknown. Around 30% of the patients are treated by surgery. The aims of this thesis were to evaluate outcome after specific surgical procedures and to investigate possible pathophysiological aspects. LÄS MER

    Sammanfattning : Inflammatory bowel disease (IBD) is a group of chronically relapsing immune-related disorders, engaging the gastrointestinal tract. Symptoms vary depending on inflammatory phenotype, but may include diarrhoea, bowel pain and weight loss. The two most common entities are Crohn's disease and ulcerative colitis (UC). LÄS MER

  7. 5. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

    Författare :Moorix Mo-Wai Yeung; Sten Hammarström; Marie-Louise Hammarström; Marita Troye-Blomberg; Umeå universitet; []

    Sammanfattning : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. LÄS MER
