Breast carcinoma has the potential for widespread dissemination. Spread to the lower gastrointestinal tract is infrequent, often multifocal, occurs in association with spread to other sites, and most commonly develops from lobular carcinoma. Solitary colorectal metastasis as the first and sole manifestation of spread is a rare occurrence and can be confused(More)
BACKGROUND Co-colonization of patients with carbapenem-resistant Enterobacteriaceae (CRE) and Acinetobacter baumannii (AB) or Pseudomonas aeruginosa (PA) is reported to be associated with increased antibiotic resistance and mortality. METHODS CREs isolated between September 2008 and September 2009 were analyzed at Detroit Medical Center. Patients who had(More)
BACKGROUND Carbapenem-resistant Enterobacteriaceae (CRE) are rapidly emerging worldwide. Control group selection is critically important when analyzing predictors of antimicrobial resistance. Focusing on modifiable risk factors can optimize prevention and resource expenditures. To identify specific predictors of CRE, patients with CRE were compared with 3(More)
We report a surveillance method for influenza that is based on automated hospital laboratory and pharmacy data. During the 2009 H1N1 influenza pandemic, this method was objective, easy to perform, and utilized readily available automated hospital data. This surveillance method produced results that correlated strongly with influenza-like illness(More)
BACKGROUND Therapeutic options are limited for infections because of Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae (CRE). Study aim was to compare the efficacy of colistin to tigecycline for the treatment of these types of infections. METHODS A retrospective study was conducted at the Detroit Medical Center. Adult patients with(More)
A phenotypic and genotypic analysis of Acinetobacter baumannii was conducted from 2003 to 2008 in Detroit, MI. The incidence of A. baumannii increased from 1.7 to 3.7/1,000 patient days during the study period. Susceptibility to ampicillin-sulbactam and imipenem decreased from approximately 90% to approximately 40%. Genotyping revealed polyclonality,(More)
BACKGROUND Carbapenem-resistant Enterobacteriaceae (CRE) are rapidly emerging in hospitals in the United States and are posing a significant threat. To better understand the transmission dynamics and the acquisition of resistant strains, a thorough analysis of epidemiologic and molecular characteristics was performed. METHODS CRE isolated at Detroit(More)
A "high risk" clone of carbapenem-resistant Klebsiella pneumoniae (CRKP) identified by multilocus sequence typing (MLST) as sequence type (ST) 258 has disseminated worldwide. As the molecular epidemiology of the CRE pandemic continues to evolve, the clinical impact of non-ST258 strains is less well defined. We conducted an epidemiological investigation of(More)
BACKGROUND Long-term acute care (LTAC) facilities admit patients with complex, advanced disease states. Study aims were to determine the burden posed on hospitals associated with LTAC exposure and analyze the differences between "present on admission" (POA) multidrug-resistant (MDR), gram-negative organisms (GNO) and POA MDR gram-positive organisms (GPO).(More)
