Pseudoseptic arthritis of the shoulder following pneumococcal vaccination.

Pseudoseptic arthritis is primarily described in rheumatoid arthritis and other systemic inflammatory conditions. To our knowledge, only 1 case report of pseudoseptic arthritis associated with intra-articular injection of a pneumococcal polyvalent vaccine (PPV) has been published. Here, a second case is presented in which a patient presented with swelling, pain, and erythema of the affected shoulder.

Radiographic analysis of the Canale view for displaced talar neck fractures.

Fractures of the talar neck comprise almost 50% of fractures of the talus and may result in significant long-term morbidity. It is of paramount importance to ensure anatomic reduction of the fracture not only for fracture healing but also for minimizing future posttraumatic arthritic sequelae. In addition to conventional radiographs and computed tomography scans, the Canale view has proven to be beneficial, especially when evaluating for varus displacement.

Additive effects of exogenous IL-12 supplementation and antibiotic treatment in infection prophylaxis.

The increasing clinical incidence and host risk of open fracture-associated infections, as well as the reduced effectiveness of conventional antibiotics to treat such infections, have driven the development of new therapies for the prophylaxis of open fracture-associated infections. We investigated percutaneous supplementation of a natural cytokine (i.e.

Failure of xenoimplantation using porcine synovium-derived stem cell-based cartilage tissue constructs for the repair of rabbit osteochondral defects.

The use of xenogeneic tissues offers many advantages with respect to availability, quality control, and timing of tissue harvest. Our previous study indicated that implantation of premature tissue constructs from allogeneic synovium-derived stem cells (SDSCs) facilitated cartilage tissue regeneration. The present study investigated the feasibility of xenoimplantation of SDSC-based premature tissue constructs for the repair of osteochondral defects.

Radiographic evaluation of the distal radius using two novel biplanar "pitch-and-roll" views: a preliminary cadaveric study.

This study's objective was to compare the use of two biplanar angled radiographs versus standard posterioanterior (PA) and lateral radiographs in determining preservation of the articular space with regard to pin placement in the distal radius. Various combinations of inclination (pitch) and clockwise/counterclockwise rotation (roll) were used to determine the best view of the distal radius articular surface. Optimum visualization of the articular surface presented at 12 degrees inclination plus 15 degrees counterclockwise rotation for the PA view and 22 degrees inclination and 15 degrees counterclockwise rotation for the lateral view.

Multilayer polypeptide nanoscale coatings incorporating IL-12 for the prevention of biomedical device-associated infections.

Biomedical device-associated infection is one of the most common and problematic complications faced by millions of patients worldwide. The current antibiotic therapy strategies face challenges, the most serious of which is antibiotic resistance. Studies have shown that the systemic level of interleukin 12 (IL-12) decreases following major injuries resulting in decreased cell-mediated immune response.
