Risk factors for superficial wound complications in hip and knee arthroplasty.
Superficial wound complications have been consistently implicated in the development of prosthetic joint infection. This cohort study aimed to determine perioperative risk factors associated with superficial wound complications. The study was performed over an 18-month period (January 2011 to June 2012) and included 964 patients undergoing prosthetic hip or knee replacement surgery. ⋯ In the hip arthroplasty cohort, the use of 0.5% chlorhexidine in 70% alcohol for surgical skin preparation (OR, 13.35; 95% CI, 2.11, 84.29; p 0.006), increasing BMI (OR, 1.13; 95% CI, 1.06, 1.19; p < 0.001) and increasing blood transfusions (OR, 1.26; 95% CI, 1.06, 1.49; p 0.008) were associated with superficial wound complications. In the knee arthroplasty cohort rheumatoid arthritis (OR, 2.75; 95% CI, 1.03, 7.33; p 0.043) and increasing tourniquet time (OR, 1.01; 95% CI, 1.00, 1.02; p = 0.029) were independent predictors of superficial wound complications. Further research is warranted to assess the impact of modification of these factors on the subsequent development of wound complications and prosthetic joint infection.

Review Practice GuidelineESCMID guidelines for the management of the infection control measures to reduce transmission of multidrug-resistant Gram-negative bacteria in hospitalized patients.
Healthcare-associated infections due to multidrug-resistant Gram-negative bacteria (MDR-GNB) are a leading cause of morbidity and mortality worldwide. These evidence-based guidelines have been produced after a systematic review of published studies on infection prevention and control interventions aimed at reducing the transmission of MDR-GNB. The recommendations are stratified by type of infection prevention and control intervention and species of MDR-GNB and are presented in the form of 'basic' practices, recommended for all acute care facilities, and 'additional special approaches' to be considered when there is still clinical and/or epidemiological and/or molecular evidence of ongoing transmission, despite the application of the basic measures. The level of evidence for and strength of each recommendation, were defined according to the GRADE approach.

Streptococcal vertebral osteomyelitis: multiple faces of the same disease.
The role of Streptococcus species as an aetiological microorganism of vertebral osteomyelitis (VO) is considered to be of little relevance. We aimed to describe a large number of cases of streptococcal vertebral osteomyelitis (SVO), to analyze the clinical features associated with different Streptococcus species, and to compare them with a cohort of patients with VO caused by Staphylococcus aureus. An incidence study and a retrospective, multicenter, observational clinical study of cases of SVO (1991-2011) were performed. ⋯ The relationship between VO and diagnosis of endocarditis was established with SVO caused by the viridans group. Whereas non-viridans SVO mimics acute characteristics of VO caused by S. aureus, cases of viridans SVO are significantly more likely to have a sub-acute clinical presentation. The increased incidence of SVO during the last decades could support a new epidemiological scenario.

ReviewNational Advisory Groups and their role in immunization policy-making processes in European countries.
During the twenty-first century, the development of national immunization programmes (NIP) has matured into robust processes where evidence-based methodologies and frameworks have increasingly been adopted. A key role in the decision-making and recommending processes is played by National Immunization Technical Advisory Groups (NITAGs). In a survey performed among European Union member states, Norway and Iceland, in February 2013, 85% of the 27 responding countries reported having established a NITAG, and of these, 45% have formal frameworks in place for the systematic development of vaccination recommendations. ⋯ Differences in the relative weighting of these key factors, differences in data or assumptions on country-specific key factors, and differences in existing vaccination systems and financing, are likely to be reasons for differences in NITAG recommendations, and eventually NIPs, across Europe. Even if harmonization of NIPs is presently not a reasonable aim, systematic reviews and the development of mathematical/economic models could be performed at supranational level, thus sharing resources and easing the present work-load of NITAGs. Nevertheless, it has been argued that harmonization would ease central purchase of vaccines, thus reducing the price and increasing access to new vaccines.

Heparin-binding protein (HBP) in critically ill patients with influenza A(H1N1) infection.
Heparin-binding protein (HBP) is an inducer of vascular endothelial leakage in severe infections. Fluid accumulation into alveoli is a general finding in acute respiratory distress syndrome (ARDS). Severe acute respiratory failure with ARDS is a complication of influenza A(H1N1) infection. ⋯ The patients with septic shock/severe sepsis (compared with those without) did not have statistically significant differences in HBP concentrations at baseline or day 2. HBP concentrations are markedly elevated in all critically ill patients with influenza A(H1N1) infection. The increase in HBP concentrations seems to be associated with more pronounced respiratory dysfunction.
