[Evidence and recommendation of empirical antimicrobial treatment in pyogenic spondylodiscitis: systematic review].

To prescribe antibiotic treatment, it is required to identify the causative organism on the basis of the epidemiology of the etiologic agent, as well as the ability of the antibiotic to penetrate the bone tissue and the intervertebral disc.

[Sensitivity and antibiotic resistance in infections of the musculoskeletal system].

Background: Infections of the musculoskeletal system are a devastating complication for patients, due to it's long rehabilitation process and even sometimes the removal of the implant, the chronicity of infection, is often due to lack of coverage in empirical antibiotics.

Methods: A retrospective, observational, descriptive cohort study was performed. All cultures form musculoskeletal system infected patients reported of sensitivity and resistance of germs isolated were analyzed.
