Objectives: Bacterial colonization on toothbrushes can cause stomatitis and other oral diseases such as dental caries and periodontitis. In this study we tested 18 toothbrushes, of which six were left exposed to the air, six were stored in a plastic bag, and six in a toothbrush case. Methods: ATP (RLU: relatively light unit) values measured by ATP Luminometer were compared with APC (CFU: colony forming unit) by swabbing culture method using 3M<sup>TM</sup> petrifilm<sup>TM</sup> aerobic count plates. Results: Swabs from toothbrushes left exposed in the air developed an average of 651.67±261.94 CFU, while the “In plastic bag” and the “In toothbrush case” specimens developed 593.17±354.33 and 120.83±68.87 CFU, respectively. Conclusion: The best option is to rinse the toothbrush well with water and to keep them dry in a well-ventilated area in order to reduce the growth of bacteria in a public bath.

Purpose: We aimed to determine the prevalence of allergic rhinitis and nonallergic rhinitis, difference in symptoms between allergic rhinitis and nonallergic rhinitis, and the association between lung function and the degree of asthma control in children with asthma. Methods: One hundred seventy patients who were followed-up for asthma treatment at the department of pediatrics of CHA Bundang Medical Center were enrolled in this study. We conducted the questionnaire regarding coexistence of rhinitis, childhood asthma control test (C-ACT), and the basic lung function test. The patients were classified as allergic rhinitis group and nonallergic rhinitis group according to the response to 11 common inhalation and food allergens, and assessed the degree of asthma control and the severity of rhinitis. Results: One hundred thirty patients (73%) were found to have rhinitis. Of these, 79 patients (53%) had allergic rhinitis and 34 patients (20%) had nonallergic rhinitis. The allergic rhinitis group was older than the nonallergic rhinitis group or the nonrhinitis group (7.73±2.85 vs. 5.97±2.48 vs. 6.12±2.70, P<0.001). Nasal itching sense was more prevalent in the allergic-rhinitis group than in the nonallergic rhinitis group (3.23±1.90 vs. 2.44±1.56, P=0.036). There was an inverse correlation between the rhinitis and C-ACT (r= -0.329, P<0.05). Of note, nasal obstruction symptom was highly correlated with C-ACT (r=-0.334, P<0.001). Conclusion: Allergic rhinitis and nonallergic rhinitis were highly prevalent in the pediatric patients with asthma and both of them had a significantly adverse impact on asthma control by rhinitis-itself. Therefore, regardless of atopic status, clinicians should focus on relieving rhinitis symptoms. (Allergy Asthma Respir Dis 2013;1:241-247)

Purpose: This study was conducted to compare clinical features between Mycoplasma pneumonia and viral pneumonia. Methods: We retrospectively analyzed the medical records of 428 patients requiring hospitalization among children younger than 18 years of age in 5 hospitals in Seoul and Gyeonggi-do. There were 131 patients with M. pneumonia and virus coinfection, 167 patients with M. pneumonia without virus coinfection, and 130 patients with viral pneumonia. All subjects had radiographic evidence of pneumonia with specimens available for both M. pneumonia and viral testing. Virus was identified using the polymerase chain reaction assay in a nasopharyngeal or oropharyngeal swab. M. pneumoniae pneumonia was diagnosed serologically. Results: Human rhinovirus was detected in 60.3% (79 of 131) of children with M. pneumonia accompanied by virus coinfection. Respiratory syncytial virus (RSV) was detected in 38.2% (50 of 130) of children with viral pneumonia. The mean age was significantly lower in the viral pneumonia group than in the M. pneumonia group with and without virus coinfection. The sex distribution did not differ significantly among the 3 study groups. The procalcitonin level was higher in viral pneumonia and erythrocyte sedimentation rate level was higher in the M. pneumonia group although no significant difference was found in C-reactive protein level between the M. pneumonia and viral pneumonia groups. Conclusion: Clinical features and inflammatory markers between M. pneumonia and viral pneumonia may be useful for the treatment of community-acquired pneumonia.
