    Sammanfattning : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. LÄS MER

  7. 5. Gluten challenge in children with coeliac disease. With special reference to dose dependence and impact on growth markers and growth hormone secretion

    Författare :Ulf Jansson; Göteborgs universitet; []
    Nyckelord :Coeliac disease; children; gluten challenge; gluten dose; symptoms; enteropathy; ALP; ALAT; ASAT; albumin; IGF-I; GH.;

    Sammanfattning : Coeliac disease is a prevalent food intolerance in both children and adults, in which ingestion of gluten causes inflammation of the small intestine. This inflammation resolves upon gluten withdrawal, and gluten challenge induces relapse of enteropathy in susceptible individuals. LÄS MER
