Sleep-disordered breathing (SDB) induces dysfunction of the orofacial muscles, leading to morphologic alteration of the face and dental malalignment. Early diagnosis and treatment of SDB is required in pediatric patients to ensure normal facial growth. Myofunctional therapy (MFT) is a modality for the treatment of SDB and prefabricated appliances can be used. Herein 2 cases of malocclusion with SDB, in which MFT with a prefabricated appliance was used for orthodontic treatment, have been described. SDB was diagnosed based on clinical symptoms taken by interview and home respiratory polygraphy. In both cases, SDB was improved using prefabricated appliance for MFT. However, resolution of crowding depended on the degree of crowding.

BACKGROUND: Carotid intima media thickness (CIMT) and the presence of carotid plaque have been used for risk stratification of cardiovascular disease (CVD). To date, however, the association between multi-directional functional properties of carotid artery and CVD has not been fully elucidated. We sought to explore the multi-directional mechanics of the carotid artery in relation to cardiovascular risk. METHODS: Four hundred one patients who underwent carotid ultrasound were enrolled between January 2010 and April 2013. A high risk of CVD was defined as more than 20% of 10-year risk based on the Framingham risk score. Using a speckle-tracking technique, the longitudinal and radial movements were analyzed in the B-mode images. Peak longitudinal and radial displacements, strain and strain rate were also measured. Beta stiffness and elastic modulus index were calculated from the radial measurements. RESULTS: Of the overall sample, 13% (52) of patients comprised the high-risk group. In multivariate logistic regression, CIMT and elastic modulus index were independently associated with a high-risk of CVD {odds ratio (OR): 1.810 [95% confidence interval (CI) 1.249–2.622] and OR: 1.767 (95% CI: 1.177–2.652); p = 0.002, 0.006, respectively}. The combination of CIMT and elastic modulus index correlated with a high-risk of CVD more so than CIMT alone. CONCLUSION: The elastic modulus index of the carotid artery might serve as a novel surrogate marker of high-risk CVD. Measurement of the multi-directional mechanics of the carotid artery using the speckle tracking technique has potential for providing further information over conventional B-mode ultrasound for stratification of CVD risk.

BACKGROUND: Disability of Activities of daily living (ADL) is the most important factor for care of dementia patients. So Korean Dementia Association has prepared the survey for current state and cognition of active daily living in Korean dementia patients. METHODS: A total of 100 subjects were interviewed. Structured open and closed questions about ADL for dementia were asked. They are main caregivers of dementia patients who working over 5hours per day. Assessments included age, sex, education level, economic status, severity of dementia patients, pattern of the care-giving, current state and cognition of ADL, and needs of the caregivers. RESULTS: The cognition of ADL was very low (51%) and this is correlated with economic status. Increasing of care-giving time is the most stressful for caregivers, they frequently suffered from disability of outgoing and personal hygiene. Dementia patient's ADL disability causes serious economic losses, need of the caregivers about guide lines or education program was very high. CONCLUSION: Considering these results, we should design more detailed study about dementia patient's ADL disability and prepare guide line or program for it.

Sixteen genomic DNA simple sequence repeat (SSR) markers of Lentinula edodes were developed from 205 SSR motifs present in 46.1-Mb long L. edodes genome sequences. The number of alleles ranged from 3–14 and the major allele frequency was distributed from 0.17–0.96. The values of observed and expected heterozygosity ranged from 0.00–0.76 and 0.07–0.90, respectively. The polymorphic information content value ranged from 0.07–0.89. A dendrogram, based on 16 SSR markers clustered by the paired hierarchical clustering' method, showed that 33 shiitake cultivars could be divided into three major groups and successfully identified. These SSR markers will contribute to the efficient breeding of this species by providing diversity in shiitake varieties. Furthermore, the genomic information covered by the markers can provide a valuable resource for genetic linkage map construction, molecular mapping, and marker-assisted selection in the shiitake mushroom.

The purpose of this study was to improve efficacy of oral health education in children and adolescents based on the experience and perception of oral health education in young adults who graduated from high school within 10 years.Questionnaires were given to 412 people, and among them, 388 completed survey forms were selected. The questionnaire included categories which examined one's experience and perception of oral health education, oral health knowledge, dental history, and oral health behavior.The results showed that the respondents perceived elementary school as the most effective period of oral health education. Oral examination with direct explanation was the most preferred method of oral health education, but web search was the main source of oral health information. And knowledge of fluoride and sealant about caries preventive effect was still lacking. Considering these results, oral examination with direct explanation and web search would be useful to improve efficacy of oral health education in children and adolescents.

BACKGROUND: Activities daily living (ADL) disability has a direct influence on the patients' quality of life and on the amount of care needed. It is major factor of care in dementia patients. So Korean Dementia Association suggested guideline about activities of daily living in dementia patients in 2013. The purpose of this article is to investigate the effect of this. METHODS: A total of 110 subjects were enrolled. Assessments included age, sex, education level of patients and caregiver, the duration of disease, pattern of family, economic status. We divided "active practice" group and "passive practice" group by recognition of guideline contents after study. We compared two groups before and after by Korean Mini-Mental State Examination (K-MMSE), Short form of Geriatric Depression Scale-Korean version (S-GDS), Korean version of Zarit's Burden Interview (ZBI-K), Alzheimer's Disease Cooperative Study-Activities of Daily Living scale (ADCS-ADL). Finally, we investigate the level of satisfaction about our guideline. RESULTS: Age of patients, the duration of disease was lower and education level of caregiver and economic status was higher in "active practice group". The pattern of family also differed from two groups. It was observed distinct difference between the variations of two groups in S-GDS, ZBI-K, and ADCS-ADL. The level of satisfaction about our guideline was very high. CONCLUSION: Considering these results, our guideline about activities of daily living is effective to manage dementia patient. Active application of it is needed in clinic or center for dementia.
