To determine the epidemiologic features and clinical outcomes of bloodstream infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae isolates, cases of bacteremia caused by these organisms in children were analyzed retrospectively. Among the 157 blood isolates recovered from 1993 to 1998 at the Seoul(More)
BACKGROUND The association between epicardial fat and coronary artery disease has not been evaluated. The objective of the present study was to evaluate the relationship of echocardiographic epicardial fat to the presence and severity of coronary artery disease in a clinical setting. METHODS AND RESULTS Two hundred and three consecutive patients who(More)
Adenovirus is an important cause of respiratory infections in infants and children. Fifty-one serotypes have been identified, and adenovirus type 3 (Ad3) and Ad7 have often been associated with outbreaks of severe respiratory tract infections. Each serotype can be further divided into genome types based on the patterns of digestion of their DNAs with(More)
BACKGROUND Hspa1a and Hspa1b genes encode stress-inducible 70-kDa heat shock proteins (Hsp70) that protect cells from insults such as ischemia. Mice with null mutations of both genes (KO) were generated, and their cardiac phenotype was explored. METHODS AND RESULTS Heart rate and blood pressures were normal in the KO mice. Hearts from KO mice were more(More)
Bacterial meningitis remains a serious cause of morbidity and mortality in childhood, despite the availability of effective vaccines against Haemophilus influenzae type b (Hib) or Streptococcus pneumoniae. The purpose of this study was to analyze data on bacterial meningitis cases in Korea from 1996 through 2005. The information of all hospitalized(More)
Of 72 blood isolates of Enterobacter spp. collected over an 8-year period, 50% (36 of 72) were derepressed or partially derepressed AmpC mutants. The extended-spectrum beta-lactamase (ESBL) production rate was 43% (31 of 72 isolates), and 67.3% (31 of 46) of extended-spectrum cephalosporin-resistant strains produced ESBLs. Thus, a confirmatory test for ESBL(More)
Obesity is a major risk factor for hypertension, coronary artery disease and type 2 diabetes. Weight loss is associated with significant metabolic benefits. Our objective was to examine changes in adipocytokines and interleukin (IL) 10 in obese subjects before and after weight loss. We measured anthropometric parameters, adipocytokine and IL-10 in 78 obese(More)
In many types of heart failure cardiac myocyte Ca(2+) handling is abnormal because of downregulation of key Ca(2+) - handling proteins like sarco(endo)plasmic reticulum Ca(2+) - ATPase (SERCA)2a and ryanodine receptor (RyR)2. The alteration in SERCA2a and RyR2 expression results in altered cytosolic Ca(2+) transients, leading to abnormal contraction. Sorcin(More)
To define the role of human metapneumovirus (hMPV) in previously healthy Korean children, a retrospective study was done on 166 children with lower respiratory tract infections and on their stored nasal aspirates. The hMPV gene was detected by reverse transcriptase-polymerase chain reaction. Twenty-six of 166 individuals tested positive for hMPV. The(More)
OBJECTIVES This ambidirectional intervention study was performed to examine the impact of a change in antibiotic policy on extended-spectrum beta-lactamase (ESBL) prevalence in a children's hospital with a high prevalence of ESBL production among Escherichia coli and Klebsiella pneumoniae. METHODS The use of extended-spectrum cephalosporins was restricted(More)
