Clinical patterns of Klebsiella pneumoniae bacteraemia vary geographically. An invasive syndrome involving abscess formation has emerged in recent years. Putative virulence factors associated with this syndrome include colony hypermucoviscosity, and magA and rmpA genes. We studied epidemiologic and microbiologic characteristics of K. pneumoniae bacteraemia at two South Australian hospitals and identified cases of K. pneumoniae invasive syndrome. We determined the frequency of the hypermucoviscosity, magA and rmpA genes among bacteraemic and selected non-bacteraemic isolates. ⋯ This study augments understanding of local epidemiology and microbiology of K. pneumoniae bacteraemia. It confirms local emergence of K. pneumoniae invasive syndrome and implicates the role of magA and rmpA genes in its pathogenesis.

Efficacy and safety of voriconazole in the treatment of chronic pulmonary aspergillosis: experience in Japan.
Though various clinical conditions of aspergillosis can occur, depending essentially on the host's immunological status, the focus of research in North American and European countries has mainly been on invasive pulmonary aspergillosis in immunocompromised patients. There are, however, also many problems to overcome in chronic forms of aspergillosis. One of those problems is that there are no codified treatment guidelines for chronic pulmonary aspergillosis (CPA). Especially in Japan, this issue is more serious, because there are more cases with CPA due to the many aged people with past history of tuberculosis. Several clinical cases and case series have reported the usefulness of the various antifungal agents that are available. The new triazole, voriconazole, in particular, seems to be effective in the treatment of CPA. The aim of the present study is to evaluate the efficacy and safety of voriconazole in the treatment of CPA in non-immunocompromised patients. ⋯ In Japan, voriconazole provides effective therapy of CPA in non-immunocompromised patients with an acceptable level of toxicity.

Adherence to guidelines for antibiotic prophylaxis in surgery patients in German hospitals: a multicentre evaluation involving pharmacy interns.
Surgical site infections (SSIs) are associated with a high morbidity, mortality and healthcare costs. The prevention of SSIs is based on a combination of preoperative preparation, surgical techniques, perioperative antibiotic prophylaxis (PAP) and postoperative wound care. Despite an abundance of evidence demonstrating the effectiveness of antimicrobials to prevent SSIs, the use of antimicrobial prophylaxis in this clinical setting is associated with inappropriate timing and selection and excessive duration of administration. To date, pharmacy interns (PIs) have not been involved in this process. The aim of this study was to evaluate feasibility of involving PIs in monitoring adherence to the guidelines for antibiotic prophylaxis in surgery patients. ⋯ The study revealed that many patients do not receive the appropriate antibiotic prophylaxis despite the fact that guidelines are in place. Based on these results, we conclude that PIs may play an important role in antibiotic prophylaxis management.

To describe the clinical features, risk factors for severe disease and effectiveness of oseltamivir in patients with 2009 pandemic influenza A (H1N1) virus infection. ⋯ During the 2009 H1N1 influenza pandemic, elderly or obese patients and those with neurological disease had an increased risk for severe H1N1 infection in Austria. Pregnancy was not associated with a higher risk for severe disease in the later phase of the 2009 H1N1 pandemic. Antiviral treatment provided a minimal effect on the symptoms of influenza but reduced the risk of admission to an ICU.

Promoting Global Research Excellence in Severe Sepsis (PROGRESS): lessons from an international sepsis registry.
The PROGRESS Registry (Promoting Global Research Excellence in Severe Sepsis) was designed to provide comparative data reflecting everyday clinical practice, thereby allowing participating institutions to explore and benchmark medical interventions in severe sepsis. ⋯ The PROGRESS international sepsis registry demonstrates that a large web-based sepsis registry is feasible. Wide variations in outcomes and use of sepsis therapies were observed between countries. These results also suggest that additional opportunities exist across countries to improve severe sepsis outcomes.
