We controlled the spread of epidemic methicillin-resistant Staphylococcus aureus (MRSA) infection in an 884-bed veterans' facility by cohorting known active MRSA carriers and MRSA-infected patients on one nursing unit. Simultaneously, all previously-institutionalized transfers into the veterans' facility were screened with swab cultures for MRSA at the time of admission. All MRSA patients were maintained on contact (gown and glove) or strict isolation and treated aggressively with topical and enteral antibiotics with the assistance of the infectious disease consultant. The monthly incidence of new MRSA patients dropped from a maximum of 16 per month to three or less per month within six months of instituting these infection control measures. There were no further MRSA bacteremias after the establishment of the MRSA cohort in a single unit. Aggressive cohort management of known MRSA patients and screening of previously-institutionalized patients on admission for MRSA controlled epidemic MRSA in this large institution.
A 44-year-old man with end-stage ischemic cardiomyopathy was supported with an intra-aortic balloon and The Penn State Heart (artificial) prior to orthotopic cardiac transplantation on the 14th hospital day. At the time of transplantation, intraoperative cultures of pericardial and mediastinal fluid showed growth of Trichosporon beigelii (cutaneum). Shortly thereafter the patient developed visceral dissemination of T beigelii with no associated skin lesions. He was treated with amphotericin B and rifampin, but postmortem examination showed persistent, disseminated infection.
A 32-year-old man with systemic lupus erythematosus controlled by steroid therapy developed multifocal cutaneous abscesses caused by Mycobacterium scrofulaceum. The distribution and evolution of the lesions suggested hematogenous dissemination, but he exhibited no pulmonary or other visceral manifestations of systemic mycobacterial disease. The patient completed nine months of therapy with isoniazid and rifampin, and the lesions resolved within five months of presentation.

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.
