  1. 1. Endoscopic retrograde cholangiopancreatography : Perforation and long-term outcomes after endoscopic sphincterotomy

    Författare :Ann Langerth; Britt-Marie Karlson; Bengt Isaksson; Per Hellman; Riadh Sadik; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long-term outcome; ERCP; perforation; endoscopic sphincterotomy;

    Sammanfattning : Endoscopic retrograde cholangio pancreatography (ERCP) is a commonly used procedure in various disorders of the pancreatobiliary tract. When extracting common bile duct stones (CBDS), the major duodenal papilla is divided using a papillotome to perform an endoscopic sphincterotomy (ES). LÄS MER

  3. 2. Extracellular matrix remodelling proteases in acute appendicitis and their impact on appendiceal perforation

    Författare :Anna Solberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; appendicitis; perforation; extracellular matrix; MMP-9; TIMP-1; uPA; PAI-1;

    Sammanfattning : Abstract Background Appendicitis is associated with varying degradation of extracellular matrix involved in tissue injury. The principal aim of this study was to investigate whether immunoreactive techniques could illustrate the course and severity of appendicitis and separate the different inflammatory grades, phlegmonous, gangrenous and perforated appendicitis, from each other and from uninflamed appendix.

  4. 3. Silicone obturators and the bacterial flora in symptomatic nasal septal perforations

    Författare :Anna Karin Hulterström; Anders Berglund; Diana Berggren; Åke Davidsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nasal mucosa; perforation; symptomatic; inflammation; Staphylococcus aureus; obturator treatment; medical silicone; wettability;

    Sammanfattning : Background A perforation in the nasal septum can cause symptoms such as bleeding, obstruction, crusts and pain, and can be a challenge to treat. Surgery is the treatment of choice, but disease, size of the perforation, or the patient’s wish may contradict surgery. LÄS MER

  5. 4. Concrete Structures Subjected to Fragment Impacts

    Författare :Joosef Leppänen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perforation; penetration; strain rate; scabbing; dynamic loading; fragment and projectile impacts; numerical simulations; spalling; concrete; blast wave;

    Sammanfattning : As concrete is commonly used for protective structures, how a blast wave and fragment impacts from an explosion affect the concrete is an important issue. Concrete subjected to explosive loading responds very differently from statically loaded structures. LÄS MER

  7. 5. Perforations of the Upper Gastro-Intestinal Tract

    Författare :Michael Hermansson; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Prognostic factors; Incidence; Surgery; Diagnostic methods; Proton pump inhibitors; NSAID; Peptic ulcer perforation; Esophageal perforation; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Material and methods: In all, 237 consecutive patients with a perforated peptic ulcer admitted from 1974-1992 and 125 consecutive patients with an oesophageal perforation admitted from 1970-2006 to Lund University hospital were studied retrospectively. Prognostic factors were evaluated using the Cox proportional hazards model. LÄS MER
