  1. 1. The Renin Angiotensin System in the Human Esophageal Mucosa − expression, actions and potential involvement in reflux disease

    Author : Eleonora Björkman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endoscopic biopsies; epithelial electrical current; epithelial electrical resistance; esophageal mucosae; gastroesophageal reflux disease; mucosal barrier integrity; renin angiotensin system;

    Abstract : The renin angiotensin system (RAS) is a classical endocrine system, regulating body fluid balance and blood circulation. Recent research has shown that the system is being also locally expressed and active in several organs and tissues. READ MORE

  2. 2. Endoscopic methods for detecting malignancy in patients with ulcerative colitis and primary sclerosing cholangitis

    Author : Bo Lindberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Ulcerative colitis; primary sclerosing cholangitis; cholangiocarcinoma; colorectal cancer; dysplasia; brush cytology; Endoscopic Retrograde Cholangiopancreatography ERCP .;

    Abstract : Ulcerative colitis (UC) is a chronic ulcerative inflammatory bowel disease affecting the mucosa of the large intestine. UC patients have an increased risk for the development of colorectal cancer mainly associated with long duration and extensive involvement of the colitis. READ MORE

  3. 3. Peptic ulcer disease in an adult population : the Kalixanda study : a population-based endoscopic study

    Author : Pertti Aro; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Epidemiology; esophagogastroduodenoscopy EGD ; peptic ulcer disease PUD ; population-based.;

    Abstract : Introduction: The pattern of symptoms and perception of disease among patients seeking care does, due to health care seeking behaviour, most probably not reflect the true health status in the general population. Upper esophagogastroduodenoscopy (EGD) is considered to be gold standard for upper gastrointestinal (GI) disease assessment, but is seldom used in epidemiological studies. READ MORE

  4. 4. The papilla of Vater : issues relevant to transpapillary cannulation and clinical management

    Author : Erik Haraldsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Background: Many endoscopists have since the beginning of endoscopic retrograde cholangiopancreatography (ERCP) commented on the variation in the macroscopic appearance of the papilla of Vater. How the macroscopic appearance of the papilla influences the cannulation efforts during ERCP has been discussed but not previously investigated in-depth. READ MORE

  5. 5. 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 : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.
