Association between isolation sites of methicillin-resistant Staphylococcus aureus (MRSA) in patients with MRSA-positive body sites and MRSA contamination in their surrounding environmental surfaces.
In 106 inpatients with methicillin-resistant Staphylococcus aureus (MRSA)-positive body sites, MRSA contamination on their surrounding environmental surfaces and the palm of their dominant hand were detected and quantified. The association between MRSA-positive sites (palm of dominant hand, sputum, nasal discharge, pharyngeal mucosa, open pus, closed pus, urine, feces, and others) in patients and MRSA contamination in their surrounding environmental surfaces was evaluated by quantification theory II of multivariate analysis. The surrounding environmental surfaces were contaminated with MRSA in 54 (50.9%) of the 106 patients. ⋯ In the palm, 6,743.3 +/- 65,446.5 cfu/palm MRSA was detected in 29 (29.6%) of 98 patients. MRSA in patients' palms had the most marked influence on MRSA contamination of their surrounding environmental surfaces. When MRSA is detected in patients' palms the possibility of MRSA contamination of their surrounding environmental surfaces is high.

First report on clinical features of Mycoplasma pneumoniae infections in Vietnamese children.
Mycoplasma pneumoniae is a common cause of community-acquired pneumonia (CAP) in children, but there has been no clinical report on M. pneumoniae infections in Vietnamese children. We investigated the clinical features of M. pneumoniae infection when the pathogen was detected in the respiratory tract in hospitalized children aged 1-15 years due to lower respiratory tract infections or CAP in Vietnamese children. Throat swabs from 47 patients (18.6%) of 252 patients with a clinical diagnosis of CAP were PCR positive (male, 34; female, 13), and 21 throat swabs (8.3%) showed culture positive for M. pneumoniae. ⋯ The major clinical signs in the 52 patients were fever (>38 degrees C) in 100%, pharyngitis in 100%, tachypnea in 94%, dry cough in 86.5%, and rough breathing in 83% of patients. The average term of illness prior to hospitalization was 7.5+/-4.1 days, and the average number of hospitalized days was 7.9+/-3.5 days. Beta-lactam group antibiotics, which were ineffective against M. pneumoniae infection, were used in 37 cases (71%).
