  1. 31. Middle Ear Cholesteatoma : Surgical Treatment, Follow-up and Hearing Restoration

    Författare :Lennart Edfeldt; Helge Rask-Andersen; Juha Silvola; Uppsala universitet; []
    Nyckelord :Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

    Sammanfattning : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. LÄS MER

  3. 32. Resection of colorectal liver metastases - Impact of preoperative chemotherapy

    Författare :Sam Eriksson; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal liver metastases; Preoperative chemotherapy; Liver resection; Hepatic microcirculation; Sarcopenia;

    Sammanfattning : Background Colorectal cancer is a leading cause of cancer related death worldwide. 20-30 % of patients will develop colorectal liver metastases (CRLMs). Surgical resection is the mainstay of treatment for CRLMs, and is often combined with perioperative chemotherapy, which can prolong progression-free survival after resection. LÄS MER

  4. 33. Magnetic resonance imaging and advanced imaging assessment of the growth plate in the adolescent and young adult

    Författare :Ola Kvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The growth plate is a cartilaginous structure located between the metaphysis and epiphysis in long bones. It is the centre for longitudinal growth. Longitudinal growth has a biphasic pattern with a peak during foetal and early postnatal life and another peak during puberty. LÄS MER

  5. 34. Brain imaging in extremely preterm infants : relations to perinatal factors and outcome

    Författare :Georgios Alexandrou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The survival of extremely preterm infants has improved over the last decades along with the advances in perinatal care. These immature children are born at a vulnerable stage of brain development, before entering the third trimester of gestation, and are at an increased risk for brain injuries, atypical brain development and subsequent adverse neurodevelopment.

  7. 35. Applications of nanotechnology in neuroscience : functionalized superparamagnetic nanoparticles as contrast enhancers in experimental magnetic resonance imaging

    Författare :Fu-Hua Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Magnetic resonance imaging (MRI) is a noninvasive imaging technique that helps clinicians not only to diagnose but also to plan the treatment of invasive surgery and actually treat medical conditions. Superparamagnetic iron oxide nanoparticles (SPIONs) are a family of MRI contrast agents that improves MRI sensitivity/specificity. LÄS MER
