  1. 1. Chronic Gastritis : Diagnosis, natural history and consequences

    Författare :Stefan Redéen; Kurt Borch; Fredrik Petersson; Christer Christer Staël von Holstein; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background & alms: The main cause of chronic gastritis is Helicobacter pylori (H. pylori). Clinical manifestations of chronic gastritis are ulcer disease, gastric cancer and mucosa-associated lymphoma tissue (MALT) lymphoma in the stomach. It is uncertain whether gastritis can be diagnosed macroscopically at endoscopy. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrocele; Spermatocele; Groin hernia; prostate biopsy; complication; infection; chronic pain; Urology; kirurgi; särskilt urologi; kirurgi; Surgery;

    Sammanfattning : Background:Minor procedures in surgery and urology such as groin hernia and hydrocele repair, as well as prostate biopsies are very frequently done in routine practice. Complications and insufficient outcomes thus affecting many patients and the cumulative effect of this are of major importance in a population perspective. LÄS MER

  4. 3. Induction and functional role of type I interferon in bacterial infection of macrophages

    Författare :Elin Movert; Infektionsimmunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; macrophage; Streptococcal M proteins; Mycobacterium marinum; Type I interferon; Infection;

    Sammanfattning : Infection represents an evolutionary arms race between pathogen and host. Thus, scientists find that pathogenic microbes have evolved elegant strategies to manipulate or avoid our immune system, allowing them to persist within the human population. LÄS MER

  5. 4. Immune modulation in chronic HBV and HCV infection

    Författare :Catharina Hultgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HBV; HBeAg; HCV; NS3; chronic infection; humoral cellular immune response; Th1 Th2 cells; proliferative response;

    Sammanfattning : Chronic viral hepatitis is a major health problem worldwide. The two major viral causes for chronic hepatitis are the hepatitis B (HBV) and C viruses (HCV). HBV is a DNA virus with a rather limited genetic variability whereas HCV is an RNA virus with a high genetic variability. LÄS MER

  7. 5. Aspects of chronic autoimmune thyroiditis in children and adolescents

    Författare :Johan Svensson; Pediatrisk endokrinologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescents; thyroid autoantibodies; enterovirus infection; thyroid ultrasonography; reference standard; goiter; chronic autoimmune thyroiditis; levothyroxine treatment; Medicin människa och djur ; Medicine human and vertebrates ; children;

    Sammanfattning : The aims of this thesis were to 1) compare different methods for detection of antibodies against thyroglobulin (TgAb) and thyroid peroxidase (TPOAb), particulary in children with chronic autoimmune thyroditis (AIT), 2) investigate if maternal enterovirus infection is a risk factor for development of AIT in offspring, 3) ascertain the prevalence of thyroid autoantibodies in cord blood sera from children who later developed AIT, 4) develop a new reference standard for interpretation of normative thyroid volumes in Swedish children, and 5) evaluate the effect of Levothyroxine (L-thyroxine) treatment on thyroid size in children and adolescents with AIT. We found that 1) Methods based on radioimmunoassay (RIA) were more efficient in detecting both TgAb and TPOAb in children with AIT than methods based on agglutination. LÄS MER
