Predictive model for bacteremia in adult patients with blood cultures performed at the emergency department: a preliminary report.
Useful predictive models for identifying patients at high risk of bacteremia at the emergency department (ED) are lacking. This study attempted to provide useful predictive models for identifying patients at high risk of bacteremia at the ED. ⋯ This simplified scoring system could rapidly identify high-risk patients of bacteremia at the ED.

Case ReportsNonpigmented Chromobacterium violaceum bacteremic cellulitis after fish bite.
A case of nonpigmented Chromobacterium violaceum bacteremic cellulitis after fish bite in Taiwan is reported. The patient was successfully treated with ciprofloxacin and doxycycline for an extended period. Chromobacterium violaceum should be listed in the differential diagnosis of patients with nonspecific cellulitis associated with marked leukocytosis and rapid progression to septicemia either with or without a distinct history of exposure to water or soil. A combination of prompt diagnosis, optimal antimicrobial therapy, and adequate therapeutic duration for C violaceum infection is the key for successful therapy.

Case ReportsFatal subdural empyema caused by Streptococcus constellatus and Actinomyces viscosus in a child--case report.
Group milleri streptococci that colonize the mouth and the upper airways are generally considered to be commensal. In combination with anaerobics, they are rarely responsible for brain abscesses in patients with certain predisposing factors. Mortality in such cases is high and complications are frequent. We present a case of fatal subdural empyema caused by Streptococcus constellatus and Actinomyces viscosus in a previously healthy 7-year-old girl.

In vitro activity of linezolid, tigecycline, and daptomycin on methicillin-resistant Staphylococcus aureus blood isolates from adult patients, 2006-2008: stratified analysis by vancomycin MIC.
The recent molecular epidemiological studies concerning epidemiological studies concerning methicillin-resistant Staphylococcus aureus (MRSA) blood isolates from adult patients and susceptibilities of MRSA isolates with high vancomycin minimum inhibitory concentrations (MICs) (≥2 mg/L) to linezolid, tigecycline, and daptomycin in Taiwan remain limited. The objectives of the study were (1) to better understand the change of molecular epidemiology of MRSA blood isolates and (2) to evaluate the in vitro activity of new anti-Gram-positive agents, including linezolid, tigecycline, and daptomycin. ⋯ ST239 remained predominant during the 3-year period but with a significant trend of declining. Moreover, linezolid, tigecycline, and daptomycin remained highly active against MRSA blood isolates, even with a vancomycin MIC of 2 mg/L.

Clinical manifestations and prognostic factors in cancer patients with bacteremia due to extended-spectrum β-lactamase-producing Escherichia coli or Klebsiella pneumoniae.
Clinical information about bacteremia due to extended-spectrum β-lactamase (ESBL)-producing pathogens in cancer patients was limited. The study was aimed to identify the clinical manifestations and risk factors for mortality in ESBL-producer bacteremia in cancer patients. ⋯ The presence of neutropenia or underlying hematological malignancy in cancer patients with ESBL-producer bacteremia was not associated with an increase in the mortality rate. Appropriate definitive antimicrobial therapy will be beneficial in improving clinical outcome.
