[Routine preoperative examination for diagnosis of periprosthetic joint infection and its recurrence in revision hip arthroplasty].

Objective: To evaluate diagnostic value of routine preoperative laboratory tests such as erythrocyte sedimentation rate (ESR), serum C-reactive protein (CRP) and microbiological examination of joint aspirate in patients with periprosthetic joint infection or its recurrence in patients scheduled for revision hip arthroplasty.

Material And Methods: There were 117 patients. Preoperative CRP and ESR, the culture of pre- and intraoperative joint aspirates and tissue biopsies were studied.

Chest MRI of patients with COVID-19.

During the pandemic of novel coronavirus infection (COVID-19), computed tomography (CT) showed its effectiveness in diagnosis of coronavirus infection. However, ionizing radiation during CT studies causes concern for patients who require dynamic observation, as well as for examination of children and young people. For this retrospective study, we included 15 suspected for COVID-19 patients who were hospitalized in April 2020, Russia.
