Rosacea fulminans (also known as pyoderma faciale) has been reported to occur in association with Crohn's disease. It is still unclear whether the papulopustules and confluent nodules of rosacea fulminans represent a manifestation of mucocutaneous Crohn's disease or whether this association is a mere coincidence. A 46-year-old woman presented with the spontaneous outbreak of rosacea fulminans and pyostomatitis/pyovulvitis. Complete remission of the mucocutaneous symptoms was achieved with 2 months combination therapy with methylprednisolone, isotretinoin and dapsone. The patient's Crohn's disease, already diagnosed for 3 years, did not flare during this period.
Plasma immersion ion implantation (PIII) was used to modify medical-grade PVC coated by triclosan and bronopol to enhance the antibacterial properties. The surface was first activated by O2 plasma to produce more hydrophilic groups so that triclosan and bronopol could be coated more effectively on the surface. Subsequently, an argon plasma treatment was conducted under optimal conditions to improve the antibacterial properties of the triclosan and bronopol-coated PVC samples. The modified surfaces were characterized by XPS, ATR-FTIR, SEM, and contact angle measurements. The antibacterial properties were evaluated utilizing the method of plate-counting of Staphylococcus aureus (gram positive) and Escherichia coli (gram negative). Our experimental results show that the plasma-modified PVC with bronopol exhibits good antibacterial properties while the favorable bulk properties of PVC are retained. The plasma-modified PVC with triclosan has better antibacterial performance against E. coli than bronopol. The change in the antibacterial effect on the modified PVC with time was also investigated and the antibacterial effect was observed to decrease with time.
We report a case of an intravenous drug user who already had a tricuspid bioprosthesis implanted after an infective endocarditis with massive tricuspid regurgitation one year ago. Now he presents with a large mass on the atrial side of the bioprosthesis that led to obstruction; hemocultures contained Enterococcus faecalis. After one-week therapy with antibiotics, aspirin and enoxaparin the mass untangled to a swinging structure and moderate to severe triscupid regurgitation developed; surgery appeared inevitable. After two weeks however the mass was gone, tricuspid insufficiency subsided and the patient became asymptomatic. This case illustrates the potential but controversial role of anticoagulation in the treatment of patients with infective endocarditis.
