OBJECTIVE To compare verbal and visual memory performances between patients with bipolar I disorder (BD I) and patients with bipolar II disorder (BD II) and to determine whether memory deficits were mediated by impaired organizational strategies. METHODS Performances on the Korean-California Verbal Learning Test (K-CVLT) and the Rey-Osterrieth Complex(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)
AIMS Patients with bipolar disorders (BD) show a broad range of neurocognitive impairments. We compared the patterns of neuropsychological performance in depressed and euthymic patients with BD, and explored the state-dependent cognitive markers of bipolar depression. METHODS The study participants included 32 BD patients (15 depressed and 17 euthymic)(More)
BACKGROUND   Group B streptococcus (GBS) is the most common cause of invasive neonatal infections in developed countries. The incidence of early-onset GBS disease in Korea is known to be much lower than that in other developed countries; however neonatal GBS disease has been frequently reported in recent years in Korea. This retrospective study sought to(More)
SUMMARY BACKGROUND Live, attenuated varicella vaccine has been used since 1988 in Korea. However, varicella is still prevalent among both vaccinated and unvaccinated individuals, despite a relatively high level of immunization rate up to 80%. A recent report has demonstrated approximately 20% of primary vaccine failure rate after one dose of varicella(More)
The majority of Korean patients with pandemic influenza A (H1N1) during the 2009 epidemic were under 20 yr of age. The limited data on the clinical characteristics of these children led us to conduct a case note-based investigation of children admitted to 6 university hospitals with 2009 H1N1 influenza. A total of 804 children was enrolled. The median age(More)
The purpose of this study was to identify the major etiological agents responsible for invasive bacterial infections in immunocompetent Korean children. We retrospectively surveyed invasive bacterial infections in immunocompetent children caused by eight major pediatric bacteria, namely Streptococcus pneumoniae, Haemophilus influenzae, Neisseria(More)
During a survey of the prevalent subtypes of extended-spectrum beta -lactamases in a university hospital in Korea, a nosocomial outbreak of Escherichia coli producing CTX-M-15 and OXA-30 beta -lactamases was detected. The outbreak comprised various infections, including bloodstream infections and colonization, and persisted for several months in various(More)
Children in South Korea are vaccinated with either BCG Pasteur vaccine intradermally (ID), or with BCG Tokyo vaccine given by multipuncture device (MP). Data from a recent national survey indicated that in children under 6 years old, 31.1% had received the ID vaccine and 64.5% the MP vaccine. To compare the T cell responses induced by the two vaccines,(More)
We administered both the rapid antigen test and real-time reverse transcriptase polymerase chain reaction (RT-PCR) test to 2154 patients in order to assess the diagnostic value of the rapid antigen test during Korean pandemics of H1N1 2009. The overall sensitivity was 70.0%, specificity was 97.5%, positive predictive value was 97.4%, and negative predictive(More)
