    Abstract : 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.

  2. 2. Aspects of chronic autoimmune thyroiditis in children and adolescents

    University dissertation from Institutionen för kliniska vetenskaper, Malmö

    Author : Johan Svensson; Lunds universitet.; Lund University.; [2006]
    Keywords : thyroid autoantibodies; adolescents; enterovirus infection; thyroid ultrasonography; reference standard; goiter; chronic autoimmune thyroiditis; levothyroxine treatment; Medicin människa och djur ; Medicine human and vertebrates ; children; MEDICIN; MEDICINE;

    Abstract : 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. READ MORE

    Abstract : Hepatitis B virus is a non-cytopathic virus with a small, circular, partially double-stranded DNA of 3.2 kb. It causes acute and chronic inflammatory liver disease and hepatocellular carcinoma (HCC). Retesting of stored sera from an outbreak of acute hepatitis in 1969-72 allowed identification of 126 cases of acute hepatitis B. READ MORE

  5. 5. Platelet reactivity and comorbidities in acute coronary syndrome

    Abstract : Background In the event of an acute coronary syndrome (ACS), the risk of death and complications such as stroke and re-infarction is high during the first month. Diabetes, impaired kidney function, elevated markers of systemic inflammation and high level of platelet reactivity have all been associated with worsened prognosis in ACS patients. READ MORE
