BACKGROUND Clinical outcomes of spontaneous bacterial peritonitis (SBP) due to extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella species (ESBL-EK) have not been adequately investigated. METHODS We conducted a retrospective matched case-control study to evaluate the outcomes of SBP due to ESBL-EK compared with those due to(More)
BACKGROUND This study was conducted to evaluate the risk factors for infection and clinical outcomes of bacteremic spontaneous bacterial peritonitis (SBP) due to ESBL-producing E. coli and K. pneumoniae, in patients with advanced liver cirrhosis. METHODS The ESBL production was determined by NCCLS guidelines and/or double-disk synergy tests, on stored E.(More)
Six men (mean age: 36.3 +/- 29 years) infected with the human immunodeficiency virus (HIV), four Japanese and two from Myammar, were admitted to our hospital for treatment of tuberculosis. In five, HIV positivity on serologic testing was first found when tuberculosis was diagnosed. The mean CD4 cell count was 37.3 +/- 29.6/microliters. Results of tuberculin(More)
The incidence of specific intracranial parenchymal lesions of HIV-infected patients varies considerably between countries. In the Republic of Korea, the number of HIV-infected patients is increasing, but little is known regarding the spectrum of intracranial parenchymal lesions in these patients. The aim of the present study was to obtain this information.(More)
Since the first case of human immunodeficiency virus (HIV) infection in the Republic of Korea (ROK) was detected in 1985, 876 HIV-infected patients have been reported, as of December 1998. The male to female ratio was 6.8:1, and 87% of the patients were between 20 and 49 years of age. The major modes of transmission were sexual contacts, accounting for 86%(More)
High-level gentamicin resistance (HLGR) in enterococci has increased since the 1980s, but the clinical significance of the resistance and its impact on outcome have not been established. One hundred and thirty-six patients with bacteremia caused by enterococci with HLGR (HLGR group) were compared with 79 patients with bacteremia caused by enterococci(More)
This study was performed to evaluate the effect of granulocyte-colony stimulating factor on neutrophil functions in diabetic patients with active foot infections in vitro. Twelve diabetic patients with foot infections and 12 normal volunteers were enrolled. Neutrophils from peripheral blood were incubated with granulocyte colony-stimulating factor (G-CSF,(More)
A wide variety of neurologic complications associated with human immunodeficiency virus-type 1 (HIV-1) infection result from HIV-1 itself or secondarily related to immunosuppression. In Korea, the number of HIV-1 seropositive populations is increasing, but little has been known about the neurologic complications of HIV-1 infection. To investigate the(More)
We encountered a 32-year-old Korean woman who developed murine typhus in a laboratory. She worked as a technician in a laboratory for rickettsial disease. Immunofluorescence test with rickettsial antigen (R. typhi) was positive at 1: 320 on admission and 1: 1280 after 4 weeks. A dose of 200 mg of doxycycline for 7 days proved to be effective for her(More)
