PURPOSE: We analyzed the pulmonary function and risk factors of allergic rhinitis (AR) in dust mite-sensitized children with current AR and no history of asthma. METHODS: In this cross-sectional study, demographic and disease-related information was obtained from 1,792 Korean children aged 9-12 years using a questionnaire, skin-prick testing, spirometric analysis, and methacholine challenge testing. RESULTS: A total of 672 children were analyzed. The control group consisted of 583 children without any allergic diseases who were not sensitized to 16 common allergens. The group with current AR and dust mite sensitization consisted of 89 children. Binary logistic regression analysis showed that helminth infection (adjusted odds ratio [aOR], 2.88; 95% confidence interval [CI], 1.23-6.77) and antibiotic use during infancy (aOR, 1.89; 95% CI, 1.10-3.25) were the risk factors. Pet ownership (aOR, 0.32; 95% CI, 0.15-0.69) and older siblings (aOR, 0.58; 95% CI, 0.35-0.96) were protective factors. Spirometry results did not differ between the control and dust mite-induced AR groups. None of the children showed a bronchodilator response. However, 8.5%, 7.1%, and 2.1% of the control-group children and 28.7%, 23.0%, and 8.0% of the dust mite-induced AR-group children showed methacholine PC20 (provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 second) values of < or =25 mg/mL, < or =16 mg/mL, and < or =8 mg/mL, respectively (P<0.01). CONCLUSION: The prevalence of current dust mite-induced AR may be reduced by controlling environmental factors. Even though the spirometry results seemed to be normal, bronchial hyperresponsiveness occurred more frequently in children with dust mite-induced AR than in normal children.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the usefulness of speech mapping based on real ear measurement for routine hearing aid fitting and to compare functional gains for evaluating subjective satisfaction of hearing aid users. SUBJECTS AND METHOD: Twenty two participants with bilateral symmetric (< 10 dB HL difference) sensorineural hearing loss were enrolled in this study. All participants were fitted unilateral hearing aids with speech mapping using the National Acoustic Laboratories-Nonlinear 2 formula. After the initial fitting, patients were followed with the 2nd and 3rd fitting at two weeks and six weeks, respectively, and measured for aided pure tone average (PTA), aided speech discrimination score (SDS), the difference between target gain and real ear insertion gain (REIG) using speech mapping and subjective satisfaction via Korean Adaptation of the International Outcome Inventory for Hearing Aids (K-IOI-HA) questionnaire before further fitting was performed. We analyzed correlation of each parameter at 2nd and 3rd fitting with the K-IOI-HA score. RESULTS: Every sequential aided PTA and SDS at 2nd fitting and 3rd fitting were significantly improved after repeated hearing aid fitting (all p < 0.01). In the correlation analysis between K-IOI-HA and each parameter, the aided PTA and aided SDS did not show significant correlations with subjective satisfaction from the 2nd and 3rd fittings. But the difference between the target gain and R EIG in speech mapping showed significant negative correlations with the satisfaction scores at various speech level (r=–0.609 to –0.709, all p < 0.01). CONCLUSION: Speech mapping using real ear measurement was useful to expect subjective satisfaction of hearing aid users and it would be a valuable tool for fine tuning to achieve individual preferences.

Purpose: This study investigated changes in psychological and physiological indices in cancer survivors who participated in a forest therapy camp in Korea. Methods: A total of 37 cancer survivors (19 and 18 in the experimental and control groups, respectively) participated in this study. Over a 2-night and 3-day period, the participants in the experimental group took part in a forest therapy camp that included activities such as gymnastics, walking, five-senses experiences, and meditation. Both groups completed self-report questionnaires that measured their stress levels and profile of mood states, both before and after the forest therapy camp. Blood samples were collected to measure the levels of cortisol, serotonin, and natural killer (NK) cells. Results: After the forest therapy camp, the experimental group exhibited reduced stress levels (p = .031) and a significant improvement in total mood disturbance (p = .047) when compared with the control group. The level of serotonin also significantly increased (p < .001). However, in contrast to the prediction, a significant increase in cortisol was noted in the experimental group relative to the control group (p = .016). Moreover, no significant difference in NK cells was noted between the two groups. Conclusion Forest therapy can be easily applied to cancer survivors. The positive psychological effects of the forest therapy camp were confirmed by improvements in stress and mood states and the increased level of serotonin in forest therapy camp participants. However, there is a need for a follow-up evaluation of cortisol and NK cells due to the absence of significant between-group differences.

BACKGROUND: The purpose of this study was to determine the degree of oral care, perceived halitosis, halitosis, interpersonal relationships and oral health-related quality of life and to examine the relationships among these variables.METHODS: The participants were 94 elderly people. The questionnaire included questions on oral care, perceived halitosis, interpersonal relationships, and oral health-related quality of life. Halitosis was measured using odor breath tester.RESULTS: A total of 63.8% of the elderly did not receive regular oral care. The halitosis score was 1.59, thus indicating moderate halitosis. The current perceived halitosis figure was 1.54, participants responded that they feel slight. There was no significant correlation between halitosis and perceived halitosis. Furthermore, there was no significant difference in halitosis and perceived halitosis according to the oral care. Perceived halitosis was negatively correlated with oral health-related quality of life. Interpersonal relationships were correlated with oral health-related quality of life.CONCLUSIONS: It is necessary to actively promote the need for oral care among the elderly. Moreover, older people need regular oral care to prevent halitosis and improve their oral health-related quality of life.

BACKGROUND: Few scales are currently available to evaluate changes in hand volume. We aimed to develop a hand grading scale for quantitative assessments of dorsal hand volume with additional consideration of changes in skin texture; to validate and prove the precision and reproducibility of the new scale; and to demonstrate the presence of clinically significant differences between grades on the scale. METHODS: Five experienced plastic surgeons developed the Hand Volume Rating Scale (HVRS) and rated 91 images. Another five plastic surgeons validated the scale using 50 randomly selected images. Intra- and inter-rater agreement was calculated using the weighted kappa statistic and intraclass correlation coefficients (ICCs). Paired images were also evaluated to verify whether the scale reflected clinical differences. RESULTS: The intra-rater agreement was 0.95 (95% confidence interval, 0.922–0.974). The interrater ICCs were excellent (first rating, 0.94; second rating, 0.94). Image pairs that differed by 1, 2, and 3 grades were considered to contain clinically relevant differences in 80%, 100%, and 100% of cases, respectively, while 84% of image pairs of the same grade were found not to show clinically relevant differences. This confirmed that the scale of the HVRS corresponded to clinically relevant distinctions. CONCLUSIONS: The scale was proven to be precise, reproducible, and reflective of clinical differences.

OBJECTIVE: This study aimed to achieve expert consensus for the development of strategies emergency medical services system (EMSS) after reunification of Korean using the Delphi method. METHODS: The Delphi study was performed through several rounds from January to February in 2017. Experts who have experiences of emergency medical support in North Korea and developing countries participated in the study. Respondents were asked to express their level of agreement following 7 categories: (1) emergency medical manpower, (2) communication system, (3) emergency facilities, (4) patient transfer system, (5) consumer participation and public education, (6) insurance system, (7) disaster planning. Score 1–3 was classified as disagreement, 4–6 as medium agreement, and 7–9 as agreement and consensus was considered being achieved when more than two thirds of respondents agreed in each question. RESULTS: Response rate were 80% in the first round and 75% in the second round. Consensus was achieved in emergency medical manpower, communication system, emergency facilities, patient transfer system, and disaster planning for the important factors immediately after reunification within 5 years. Consensus was achieved in emergency medical manpower, communication system, emergency facilities, patient transfer system, consumer participation and public education, and disaster planning for the prior factors when the reunification would happen rapidly without enough preparation. CONCLUSION: Consensus was achieved in emergency medical manpower, communication system, emergency facilities, patient transfer system, disaster planning for the essential EMSS elements. The consensus was expected to utilize as a basic data for the development of EMSS preparing for reunification.
