BACKGROUND: The purpose of this study was to survey the nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA) among the patients admitted in a medical intensive care unit (MICU) and analyze risk factors associated with the colonization. METHODS: The study was carried out on patients admitted into the MICU in a 1,250-bed tertiary care university hospital from January through December 2006. Nasal surveillance cultures were obtained from patients within 24 hours of admission to the unit. Data were analyzed retrospectively by the review of medical records. RESULTS: A total of 312 patients were screened with active nasal cultures; 36 patients (11.6%) were positive for MRSA. Of these, 22 (7.1%) were positive in the nasal cultures only and 14 (4.5%) were positive in the cultures of other specimens (13, sputum; 1, joint fluid) in addition to the nasal swabs. Among the risk factors for MRSA nasal colonization were sex (man), route of admission (from other ICUs or wards), a history of ICU admission during the recent 12 months, and prolonged hospital days in ICU. CONCLUSION: MRSA nasal carrier rate was found higher in this study than in those reported in the literature. Most of the patients colonized with MRSA in the nostril were not colonized with the organism elsewhere in the body. Whether or not active surveillance for MRSA should be performed would depend on the nasal colonization rate of the patients at the time of admission to the ICU.

OBJECTIVES: Age-related differences of the brain have been obtained by various methods. This study was aimed to explore the changes of quantitative electroencephalography (qEEG) and their source localization in normal aging. METHODS: Thirty-seven healthy young adults (mean age 35.22+/-13.62 years) and thirty-nine cognitively-healthy elderly subjects (mean age 72.95+/-5.73 years) participated in the study. Resting-state EEGs were recorded while subjects were in a relaxed state. Relative qEEG powers of five frequency bands were analyzed for eye closed conditions: delta (1-3 Hz), theta (4-7 Hz), alpha (8-12 Hz), beta (13-25 Hz), and gamma (30-50 Hz). The standardized low resolution electromagnetic tomography (sLORETA) was used to identify the current source densities of each frequency band. RESULTS: The elderly group showed an increase of beta and gamma power while the reduction of delta, theta, and alpha power compared with the young group. Controlling education as a covariate, the beta power was positively correlated with age, while theta power was negatively correlated with age in all subjects. sLORETA revealed that elderly subjects had reduced current source density at the cingulate gyrus in the theta band, while increased current source densities at the frontal, parietal, insula, and limbic areas in the beta band compared with young adults. CONCLUSION: Our results suggested that qEEG could reflect normal aging. Cognitively healthy elderly subjects showed an increase of high-frequency power, while showing a reduction of low-frequency power. These functional implications were discussed.

Uterine myomas are the most common benign tumor of the female genital organ. Uterine artery embolization is well reported of primary treatment of uterine myoma. A 29 year-old nulliparous woman was diagnosed as uterine myoma by ultrasonogram. We embolize both uterine artery after treatment with GnRH analog and then we experience a case of improvement of menorrhagia, with reduction in uterine myoma size. So we report that case with a brief review.
