Post-sternotomy chronic osteomyelitis can be successfully treated mainly by systemic antimicrobial therapy alone, without mandatory surgical treatments, provided that accurate microbiological and radiological studies are performed. The presence of CoNS and Corynebacterium species seemed to be associated with a need for a prolonged combined antimicrobial therapy with a minimum of 6 months up to a maximum of 18 months. The CT scan and the 3D reconstruction of the sternum proved to be a good method to evaluate the status of the sternum and support the treatments. The VAC therapy was not useful in treating osteomyelitis, although, if used appropriately in the postoperative deep sternal wound infection with the sponge fitted between the sternal edges, it seems to be an effective method to eradicate the infection in the sternum and to prevent chronic osteomyelitis.
Introduction: Lactobacilli are currently proposed as probiotic agents in several dietary products. In blood cultures, they are usually considered as contaminants, but in recent years they have been recognized as causal infectious agents of endocarditis, urinary tract infections, meningitis, intraabdominal infections and bacteraemia.
VAC is a safe and effective option in the treatment of post-sternotomy mediastinitis, with excellent survival and immediate improvement of local wound conditions; furthermore, the use of Nitinol clips after VAC therapy demonstrated to be a safe and non-invasive option for sternal resynthesis. After VAC therapy, a reduction in number of muscular flaps used and an increase of direct sternal resynthesis were observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
