Suppression of biofilm formation under a short-term impact of low-intensity direct current and in a rat model of implant-associated osteomyelitis.

Objectives: We investigated the effect of short-term low-intensity direct current (LIDC) on .

Materials And Methods: The reference strain of was used. Experiments were performed in agar culture and on a model of rat's femur osteomyelitis.

Model of Osteomyelitis in Rats.

We developed a rat model of chronic osteomyelitis of the femur caused by Staphylococcus aureus. The clinical, histomorphological, and laboratory signs were compared in rats with osteomyelitis (infected) and control animals receiving saline. On day 21 after infection, clinical, histomorphological, and laboratory signs of chronic osteomyelitis were found in experimental rats.

[Economic aspects in sIngle-event multilevel orthopedic surgery in patients with cerebral palsy].

This article reports an assessment of direct expenses for surgical treatment of patients with cerebral palsy and secondary orthopedic complications, who have undergone single-event multilevel orthopedic surgeries (SEMLS). It has been demonstrated that modern approach based on SEMLS is substantiated from the medical point of view and at present it is also justified from the point of view of economic assistance for that type of treating activity of a Federal Centre specialized in trauma and orthopaedics. Organization of surgical treatment using multilevel orthopaedic interventions requires selection of implants for specific characteristics and, on expenditure side, not exceeding funding of direct expenses intended for this treating process.
