[Recommendations for the diagnosis of prosthetic joint infections].

Prosthetic joint infection is the most feared complication of implant surgeries. Its diagnosis continues to be a challenge since its clinical presentation is usually not very evident and overlapping. A high clinical suspicion is needed to make a timely diagnosis.

[Recommendations for prevention of surgical site infection in adult elective arthroplasty].

Surgical site infections complicating orthopedic implant surgeries prolong hospital stay and increase risk of readmission, hospitalization costs and mortality. These recommendations are aimed at: (i) optimizing compliance and incorporating habits in all surgery phases by detecting risk factors for surgical site infections which are potentially correctable or modifiable; and (ii) optimizing preoperative antibiotic prophylaxis as well as intraoperative and postoperative care.

Leflunomide use in a cytomegalovirus infection of a patient with dermatomyositis.

Human cytomegalovirus (CMV) is responsible for significant morbidity and mortality in immunocompromised populations, such as those suffering from dermatomyositis (DM). We present here a case study of a DM patient undergoing methotrexate treatment who presents with weakness, myalgia, elevated levels of hepatic transaminases and serological markers of CMV primo-infection. The antiviral activity of leflunomide against CMV was described recently.
