    Sammanfattning : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometric measurement; diagnostic imaging; elasticity imaging technique; blood supply; BMI; body position; fatty liver; liver disease; hepatic steatosis; liver fibrosis; liver stiffness; obesity; postural change; pressure; probe; sex characteristic; shear wave elastography; skin-to-liver capsule distance; transducer and ultrasonography; Radiography; radiografi;

    Sammanfattning : Background: Detecting liver disease at an early stage is important, given that early intervention decreases the risk of developing cirrhosis and subsequently hepatocellular cancer (HCC). The non-invasive ultrasound-based shear wave elastography (SWE) has been used clinically for a decade to assess liver stiffness. LÄS MER

    Sammanfattning : Microtia is a congenital malformation where the auricle is not fully developed. In some cases the malformation is complete and the auricle is absent. In Sweden the incidence of microtia is about 2 per 10,000 births. LÄS MER

  5. 4. Patellofemoral pain syndrome : clinical and pathophysiological considerations

    Författare :Jan Näslund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Patellofemoral pain syndrome; pain mechanism; bone blood flow; ischemia;

    Sammanfattning : Patellofemoral pain syndrome (PFPS) is one of the most common musculoskeletal disorders and is reported to affect 15%-33% of the active adult population and 21%-45% of adolescents. Among adolescents, the incidence is reported to be higher for girls. LÄS MER

  7. 5. Study of serotonin, innervation and sensory neuropeptides in allergic contact dermatitis

    Författare :Husameldin El-Nour; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Allergic contact dermatitis; serotonin; sensory neuropeptides; nerve density;

    Sammanfattning : In a murine model of contact allergy, 24 h after challenge with antigen, increased axonal growth using an antibody to growth-associated protein-43 (GAP-43) was seen in the epidermis and dermis of eczematous skin. Protein gene product 9.5 (PGP 9.5) positive nerve fibres tended to increase in the eczematous skin. LÄS MER
