  1. 1. Experimental implant-associated orthopaedic infections

    Författare :Åke Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Osteomyelitis; anaerobic bacteria; implant design and material; bacterial collagen- and fibronectin-binding;

    Sammanfattning : Although indispensable in today's medicine, orthopaedic implants may also cause adverse reactions. A foreign body increases the local susceptibility to colonisation by microorganisms, and hence the risk of infections. These infections are rare, but many result in prolonged or permanent impairment.

  3. 2. On the pathogenesis of infections associated with percutaneous osseointegrated orthopaedic implants

    Författare :Magdalena Zaborowska; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osseointegration; amputation prosthesis; implant-associated infection; biofilm; staphylococci; extracellular vesicles; host defence; cytokines; cell death;

    Sammanfattning : Orthopaedic implants enable the restitution of locomotor function and improve the quality of life of many people. However, biomaterial-associated infection may occur due to the propensity of microorganisms to adhere and colonize implant surfaces. LÄS MER

  4. 3. Infections associated with percutaneous osseointegrated titanium implants for limb prostheses

    Författare :Jonatan Tillander; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteomyelitis; osseointegration; percutaneous implant; titanium; amputation; long-term risk; clinical presentation; biofilm;

    Sammanfattning : Femoral amputation is a devastating event. Percutaneous, bone anchored prosthetic systems reduce problems associated with socket suspended prostheses, but the design is inherently vulnerable to infection. LÄS MER

  5. 4. Protein and Cell Interactions with Nanostructured Surfaces

    Författare :Emma Westas; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; titanium dioxide; implant associated infections; metabolomics; cellular interactions; hydroxyapatite; immune complement activation; silica; nanoparticles; photocatalysis; protein adsorption; Nanostructured implants;

    Sammanfattning : A great challenge of today’s implant development is to construct a surface that promotes tissue integration and avoids bacterial colonization. To avoid implant related infections, many argue that a surface promoting strong cell adhesion and tissue integration in favour for bacterial adhesion would solve the problem, the so-called race for the surface concept.

  7. 5. Genotypic and phenotypic characterisation of Staphylococcus epidermidis isolated from prosthetic joint infections

    Författare :Bengt Hellmark; Bo Söderquist; Magnus Unemo; Åsa Nilsdotter; Tor Monsén; Örebro universitet; []
    Nyckelord :Staphylococcus epidermidis; prosthetic joint infections; antibiotic susceptibility; virulence factors; epidemiology; MLST; agr; SCCmec; MEDICINE; MEDICIN; Biomedicin; Biomedicine;

    Sammanfattning : Staphylococcus epidermidis has emerged in recent years as an important nosocomial pathogen, especially in infections associated with implanted foreign body materials (e.g., prosthetic joints and heart valves) and in individuals with a compromised immune system (e.g. LÄS MER
