Post-Laminectomy Wound Infections: Colonized Seromas Mimicking Wound Infections.

Objective: Post-operative laminectomy wounds are frequently accompanied by seromas. Post-operative wound drainage may be colonized or infected. The differentiation of wound colonization from infection is difficult for non-infectious disease physicians.

Aerococcus christensenii native aortic valve subacute bacterial endocarditis (SBE) presenting as culture negative endocarditis (CNE) mimicking marantic endocarditis.

This is a case report of an adult who presented with apparent culture negative endocarditis (CNE) thought to be marantic endocarditis due to a B-cell lymphoproliferative disorder. This was a most perplexing case and was eventually diagnosed as subacute bacterial endocarditis (SBE) due to a rare slow growing organism. Against the diagnosis of SBE was the lack of fever, hepatomegaly, peripheral manifestations and microscopic hematuria.

Viridans streptococcal (Streptococcus mitis) biosynthetic aortic prosthetic valve endocarditis (PVE) complicated by complete heart block and paravalvular abscess.

Prosthetic valve endocarditis (PVE) may be classified clinically as early (<60 days) or late (>60 days) post-valve replacement PVE. The pathogens of early versus late PVE differ in type and virulence. Early PVE pathogens are virulent, for example, Pseudomonas aeruginosa and Staphylococcus aureus.
