  2. 1. Ulcerative colitis : colorectal cancer risk and surveillance in an unselected population

    Author : Jan Lindberg; Curt Tysk; Umeå universitet; []
    Keywords : ulcerative colitis; colonoscopic surveillance; colorectal cancer; dysplasia; DNA aneuploidy; cytokeratin; colorectal resection; early onset; Surgery; kirurgi;

    Abstract : 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. READ MORE

  4. 2. Ulcerative colitis : Imaging of inflammation

    Author : Sven Almer; Vibeke Binder; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : 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.

  5. 3. Epidemiology and genetics in ulcerative colitis with special reference to twins and smoking

    Author : Curt Tysk; Linköpings universitet; []
    Keywords : ulcerative colitis; ulcerative proctitis; epidemiology; incidence; prevalence; genetics; twins; colonic glycoproteins; smoking; primary sclerosing cholangitis; MEDICINE; MEDICIN;

    Abstract : In an epidemiologic study of ulcerative proctocolitis during the period 1963-1987, annual incidence rates increased fourfold and was during the last 10 years 13.1/105 inhabitants. The prevalence on December 31, 1987 was 234/105 inhabitants. Both rates are high but close to recent reports. READ MORE

  6. 4. Neuro-immune regulation of macromolecular permeability in the normal human colon and in ulcerative colitis

    Author : Conny Wallon; Johan Dabrosin Söderholm; Peter Naredi; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colitis; ulcerative; colon; sigmoid; cytology; immunohistochemistry; Gastroenterology; Gastroenterologi;

    Abstract : Background and aim: Persistent stress and life events affect the course of ulcerative colitis (UC) by largely unknown mechanisms. Regulation of epithelial permeability to antigens is crucial for the balance between inflammation and immuno-surveillance, and increased intestinal permeability has been shown in patients with ulcerative colitis.

  7. 5. Ulcerative Colitis - Surgery Outcome and Pathophysiological Aspects

    Author : Mattias Block; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ulcerative Colitis; Long-term Function; IPAA; IRA; Neoplasia; Surveillance; Primary Sclerosing Cholangitis; Galectins; Immunohistochemistry;

    Abstract : 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. READ MORE
