[Native Joint Septic Arthritis in Adults: Incidence in Our Group of Patients and Antibiotic Therapy Guidelines].

PURPOSE OF THE STUDY The purpose of the study is to analyse the number of adult patients treated in our department for native joint septic arthritis and to outline guidelines for antibiotic therapy. MATERIAL AND METHODS From the beginning of 2003 to the end of 2020, a total of 36,342 surgeries were performed at our department. We retrospectively reviewed and analysed all surgeries for native joint septic arthritis (a total of 538 surgical interventions).

[Outcomes of Revisions of the Acetabular Component of THA with Paprosky Type 3a and 3b Defects Using Tantalum Trabecular Metal Implants 2-10 Years Postoperatively].

PURPOSE OF THE STUDY Tantallum trabecular metal implants (Trabecular Metal Technology - TMT) considerably changed the acetabular reconstruction options in revision surgeries with extensive bone defects and distorted pelvic ring integrity. The purpose of this study is to ascertain the short-term to medium-term outcomes of acetabular reconstruction through TMT implants in patients with Paprosky type 3a and 3b acetabular defects and in case of pelvic discontinuity. MATERIAL AND METHODS The prospective monocentric study included patients in whom the revision of acetabular components in total hip arthroplasty was performed, the acetabular defect was classified as Paprosky 3a and higher, a TMT implant was used for reconstruction, and the follow-up period was at least 2 years after surgery.

[The Effect of Tranexamic Acid on Blood Loss after Primary Unilateral Total Knee Arthroplasty. Prospective Single-Centre Study].

Purpose Of The Study: Tranexamic acid is an antifibrinolytic agent which blocks plasmin-mediated fibrin degradation. It is used in surgery to reduce intra-operative and post-operative blood loss. The aim of our study was to assess the effect of tranexamic acid administration on blood loss after elective primary unilateral total knee arthroplasty.

[Pancreatic tumors with endocrine activity in adolescents].

The authors demonstrate three patients--two with a nesidioma of the B-cells with insulin production, the third had a nesidioma made up of non-B cells with clinical manifestations of gastrin hypersecretion. The surgical solution was successful in the patients with B-cell nesiodiomas.
