Prevalence and risk factors for haematogenous periprosthetic joint infection during bacteraemia.

Background: bacteraemia (SAB) may lead to periprosthetic joint infections (PJI) haematogenous spread of bacteria to the joint. Due to the risk of PJI, patients with SAB and prosthetic joint are recommended prolonged antibiotic treatment. The aim of the study was to assess the risk of PJI during SAB, and to evaluate if short treatment duration affects outcomes in patients with uncomplicated SAB and prosthetic joints without clinical signs of PJI.

Biofilm formation is associated with poor outcome in prosthetic joint infections caused by .

Background: has been described as a pathogen of increasing importance in prosthetic joint infections (PJI). Our aim was to describe the clinical presentation of PJI caused by , and to correlate the biofilm-forming ability of the bacterial isolates to clinical outcome.

Method: isolates from PJI episodes during 2015-2019 were included and analysed for biofilm formation using a microtiter plate assay.

Increased short- and long-term mortality amongst patients with early periprosthetic knee joint infection.

Background: Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) is a severe complication in terms of disability, morbidity, and cost. We performed a study to investigate whether early PJI (within 90 days of primary TKA) is associated with increased mortality. Secondary aims were to compare mortality rates over time and between surgical treatment methods.

Similar periprosthetic joint infection rates after and before a national infection control program: a study of 45,438 primary total knee arthroplasties.

Background and purpose - Strenuous efforts to minimize postoperative infection rates have been made, including the Swedish nationwide initiative Prosthesis Related Infections Shall be Stopped (PRISS). This study calculated the incidence rate of periprosthetic joint infection (PJI) following primary total knee arthroplasty (TKA) before and after PRISS. Patients and methods - All 45,438 primary TKAs registered in the Swedish Knee Arthroplasty Register (SKAR) during 2007-2008 and 2012-2013 were included.

A population-based study on the treatment and outcome of enterococcal prosthetic joint infections. A consecutive series of 55 cases.

Aim: Enterococci cause 2-11% of all prosthetic joint infections (PJI) and are generally considered difficult to treat. However, study-results are not consistent. In this study we present a population-based case series of 55 cases with enterococcal PJI, investigating treatment and outcome, as well as describing the affected patient population regarding demography and co-morbidities.

Successful outcome for patients with streptococcal prosthetic joint infections - a retrospective population-based study.

Background/aim: Streptococci cause approximately 10% of prosthetic joint infections (PJIs). The aim of this study was to identify the characteristics of patients with streptococcal PJIs and to describe the treatment and outcome of streptococcal PJIs in Skåne county between 2011 and 2015.

Methods: Patients with streptococcal PJIs with positive cultures or PCRs on samples from joint aspirate and/or periprosthetic tissue between 2011 and 2015 in Skåne county, were identified and medical records were studied.

Higher risk of revision for infection using systemic clindamycin prophylaxis than with cloxacillin.

Background and purpose - Clindamycin has not been compared with other antibiotics for prophylaxis in arthroplasty. Since 2009, the Swedish Knee Arthroplasty Register (SKAR) has been collecting information on the prophylactic antibiotic regime used at every individual operation. In Sweden, when there is allergy to penicillin, clindamycin has been the recommended alternative.

A study on the outcome of percutaneous transluminal renal angioplasty in patients with renal failure.

Background: The indications for percutaneous transluminal renal angioplasty (PTRA) in renovascular disease, as well as its benefits, remain a matter of debate. The aim of this study was to evaluate the outcome of angioplasty and to identify risk factors associated with less successful outcomes in patients with atheromatous renal artery stenosis and renal failure of varying degrees.

Methods: The results of PTRA were analyzed retrospectively in 144 patients with serum creatinine levels of >130 micromol/l.
