OBJECTIVES To investigate the clinical impact of inappropriate empirical antibiotics on patient outcome and determine the risk factors for mortality in bacteremic adults who visited the emergency department (ED). METHODS Bacteremic adults visiting the ED from January 2007 to June 2008 were identified retrospectively. Demographic characteristics, clinical(More)
To document two cases of patients who were fatally exposed to tetramethylammonium hydroxide (TMAH) on the skin and to establish a rat model to investigate the effects of dermal exposure to TMAH. The charts of two workers who died from occupational accidental exposure to TMAH were reviewed. The 4-hour lethal dose (LD₅₀) of TMAH was determined by applying(More)
OBJECTIVES The aim of this study was to determine the clinical characteristics of, antibiotic therapy for, and clinical outcome of Pseudomonas aeruginosa infection among bacteremic adults who visit the emergency department (ED). METHODS Bacteremic adults who visited the ED were identified retrospectively from January 2007 to December 2007. Demographic(More)
In this study, the therapeutic efficacy of cefazolin was compared with that of extended-spectrum cephalosporins (ESCs) (cefotaxime, ceftriaxone and ceftazidime) as appropriate empirical therapy in adults with community-onset monomicrobial bacteraemia caused by Escherichia coli, Klebsiella spp. or Proteus mirabilis (EKP). Compared with cefazolin-treated(More)
Third-generation cephalosporins (3GCs) [ceftriaxone (CRO) and cefotaxime (CTX)] have remarkable potency against Enterobacteriaceae and are commonly prescribed for the treatment of community-onset bacteraemia. However, clinical evidence supporting the updated interpretive criteria of the Clinical and Laboratory Standards Institute (CLSI) is limited. Adults(More)
Enterobacteriaceae is a leading pathogen of community-onset bacteremia. This study aims to establish a predictive scoring algorithm to identify adults with community-onset Enterobacteriaceae bacteremia who are at risk for abscesses. Of the total 1262 adults, 152 (12.0%) with abscess occurrence were noted. The 6 risk factors significantly associated with(More)
BACKGROUND Organotin compounds (OTCs) have been widely used as stabilizers in the production of plastic, agricultural pesticides, antifoulant plaints and wood preservation. The toxicity of triphenyltin (TPT) compounds was known for their embryotoxic, neurotoxic, genotoxic and immunotoxic effects in mammals. The carcinogenicity of TPT was not well understood(More)
In this study, the therapeutic efficacy of third-generation cephalosporins (3GCs) was compared with that of broader-spectrum β-lactams (BSBLs) [fourth-generation cephalosporins (4GCs) and carbapenems] as empirical therapy in adults with community-onset monomicrobial Enterobacteriaceae bacteraemia. Compared with those in the 3GC group (n = 477), a(More)
Both fluoroquinolones (FQs) and third-generation cephalosporins (3rd-GCs) are commonly prescribed to treat bloodstream infections, but comparative efficacies between them were rarely studied. Demographics and clinical characteristics of 733 adults with polymicrobial or monomicrobial community-onset bacteremia empirically treated by an appropriate FQ (n =(More)
Ocular chemical burn is a severe injury with poor outcomes. Immediate and appropriate management is highly related to prognosis. We studied the effect of cultured human adipose tissue-derived stem cells on the regeneration of the rabbit cornea after alkaline chemical burn, using used human adipose tissue-derived stem cells as the source material.(More)
