OBJECTIVES: The purpose of this study was to evaluate the effect of periodontal health promotion and oral hygiene in children using a vibrating toothbrush. METHODS: Forty-seven volunteers aged between 7-15 years participated in this study at local care centers from January to February 2013. A vibratory toothbrush for children was designed with the bristles operating on a self-vibration system that separated the head-neck part of the toothbrush from the handle. The toothbrush was designed with the aim of massaging the gingiva and reducing gingival inflammation. The papillary marginal attachment (PMA) index and O'Leary plaque index were measured by oral examinations before and at 4 weeks after brushing with the vibrating toothbrush. RESULTS: The PMA index and O'Leary plaque index were reduced from 39.20 to 25.42 (P<0.001) and from 5.56 to 2.78 (P<0.001), respectively. CONCLUSIONS: These results suggested that vibrating toothbrushes designed for children can be helpful in promoting gingival health and improving oral hygiene.

In the average adult with a normal immune state, Epstein-Barr virus pneumonia is very rare, especially in the form of interstitial lung disease. According to recent studies, the Epstein-Barr virus is also associated with lymphocytic interstitial pneumonia, AIDS and Langerhans cell histiocytosis, but not with sarcoidosis. BOOP is caused by lung injury due to an infection or drug intoxication, and is related to connective tissue disease or bone marrow transplantation, but is sometimes idiopathic. We experienced a patient with symptoms and signs of interstitial lung disease, with confirmed BOOP and EBV ingection from an open lung biopsy and serologic examination, respectively Herein, this case is reported, with a review of the literature.

PURPOSE: Currently, when injecting botulinum a toxin into the extraocular muscle, EMG (Electromyography) is used for accurate location. In this study, we examined the effects of subtenon botulinum toxin injection without EMG guidance by quantifying the morphological changes of the extraocular muscle fibers in rabbits. METHODS: Using 10 New Zealand white rabbits, 10 units of botulinum a toxin in 0.1 ml of normal saline was injected into the subtenon space of the superior rectus muscles, 5 mm from the muscle insertion in right eyes. As a control, 0.1 ml of normal saline was injected into the subtenon space of the superior rectus muscles in left eyes. At 3 weeks after injections, the bilateral superior rectus muscles of each rabbit were carefully dissected from the globe. Cross-sections of 5 micrometer thickness were obtained at the site, 5 mm from the insertion of each superior rectus muscle. Sections were stained with Masson's trichrome and observed by light microscopy. Using Image-Pro Plus software, the diameter of the orbital layer myofibers was measured and statistical analysis was done using the Kruskal-Wallis test. RESULTS: The average diameter of the orbital layer fiber cells after botulinum toxin injection was 11.5+/-2.26 micrometer at 3 weeks, whereas that of the control was 14.4+/-3.77 micrometer. The difference was statistically significant (p<0.01). CONCLUSIONS: The diameter of myofibers in the orbital layer was reduced after subtenon botulinum a toxin injection. Further studies on the duration of botulium toxin in subtenon space and the change in the size of myofibers depending on the dosage of botulinum toxin will be necessary.

BACKGROUND: The processed electroencephalograms are useful surrogate measures of quantification of volatile anesthetics effect. We hypothesized that there is a certain relationship between the end-tidal concentration of sevoflurane and approximate entropy (ApEn). The aim of this study was to investigate the effect of sevoflurane on ApEn during induction. METHODS: Fourteen patients were enrolled. With recording of the electroencephalogram at the F3, F4, P3, and P4 montages, anesthesia was induced by increasing the vapor setting of sevoflurane by 1 vol% up to 8 vol% via a facemask. When the end-tidal concentration of sevoflurane did not show any further change, we increased vapor setting of sevoflurane by 1 vol%. When the end-tidal concentration of sevoflurane did not show any further change with 8 vol% of sevoflurane vapor setting, measurement of electroencephalogram was finished. The relation between end-tidal sevoflurane concentration and ApEn was tested by Spearman correlation. RESULTS: ApEn showed a significant correlation (R = -0.7551, P < 0.0001) with end-tidal sevoflurane concentration. The final pharmacodynamic parameters estimated by a sigmoid E(max) model were described as follows: E(0) = 0.91, E(max) = 0.28, C(e50) = 1.36 vol%, gamma = 1.27, kappa(e0) = 0.67 min(-1). CONCLUSIONS: Sevoflurane induction with gradual increase of end-tidal sevoflurane concentration increases the amount of regularity in approximate entropy.
