The aim of the study was to determine the serum vitamin D levels in patients with psoriatic arthritis (PsA) and compare it with patients with rheumatoid arthritis (RA) and with osteoarthritis (OA), as well as to explore the relationship of the vitamin D level with indices of disease activity and functional ability in a real-life setting in a South-European country. ⋯ In the group of rheumatic patients, a high prevalence of serum vitamin D insufficiency/deficiency was found regardless of the type of arthritis. Patients with PsA might have higher levels of vitamin D than patients with RA, and this was associated with disease activity and functional ability. The results of this study indicate that prophylactic supplementation with vitamin D might be recommended for all rheumatic patients.

Comparative Study
Evaluation of the treatment of methicillin-resistant Staphylococcus aureus bacteremia.
Bloodstream infections are a leading cause of death in the United States. Methicillin-resistant Staphylococcus aureus (MRSA) encompasses >50% of all S aureus strains in infected hospitalized patients and increases mortality, length of stay and healthcare costs. The objective of this study was to evaluate the treatment of MRSA bacteremia with daptomycin, linezolid and vancomycin. ⋯ No difference in clinical or microbiologic cure rates was observed between groups. Daptomycin and vancomycin appear equally efficacious for MRSA bacteremia, whereas linezolid therapy was associated with higher mortality.
