The aim of this study was to compare the results of 16S/28S rRNA sequencing with the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, and synovial fluid analysis in the diagnosis of prosthetic joint infection (PJI). Between September 2015 and August 2016, 214 consecutive patients were enrolled. In the study population, there were 25 patients with a PJI and 189 controls. Of the PJI patients, 14 (56%) were women, and the mean age at the time of diagnosis was 65 years (38 to 83). The ESR and CRP levels were measured, and synovial fluid specimens were collected prospectively. Synovial fluid was subjected to reverse transcription polymerase chain reaction (RT-PCR)/sequence analysis targeting the 16S/28S rRNA, and to conventional culture. Laboratory personnel who were blind to the clinical information performed all tests. The diagnosis of PJI was based on the criteria of the Musculoskeletal Infection Society.Aims
Patients and Methods
Tranexamic acid (TXA), an inhibitor of fibrinolysis,
reduces blood loss after total knee arthroplasty. However, its effect
on minimally invasive total hip arthroplasty (THA) is not clear.
We performed a prospective, randomised double-blind study to evaluate
the effect of two intravenous injections of TXA on blood loss in
patients undergoing minimally invasive THA. In total, 60 patients (35 women and 25 men with a mean age of
58.1 years; 17 to 84) who underwent unilateral minimally invasive
uncemented THA were randomly divided into the study group (30 patients,
20 women and ten men with a mean age of 56.5 years; 17 to 79) that
received two intravenous injections 1 g of TXA pre- and post-operatively
(TXA group), and a placebo group (30 patients, 15 women and 15 men
with a mean age of 59.5 years; 23 to 84). We compared the peri-operative
blood loss of the two groups. Actual blood loss was calculated from
the maximum reduction in the level of haemoglobin. All patients
were followed clinically for the presence of venous thromboembolism. The TXA group had a lower mean intra-operative blood loss of
441 ml (150 to 800) This prospective, randomised controlled study showed that a regimen
of two intravenous injections of 1 g TXA is effective for blood
conservation after minimally invasive THA. Cite this article:
