BACKGROUND: Respiratory atopy (RA) is frequently associated with atopic dermatitis (AD) and the age of onset is usually later than that of the dermatitis. OBJECTIVE: The aim of this study was to investigate the prevalence, the onset, and the duration of RA associated with AD in Korea. We also tried to correlate the existence of RA with the severity and prognosis of AD. METHODS: One hundred and eighty one patients with AD were studied. Information about the age at onset and the duration of RA were obtained from the medical history of patients or from the medical records. The severity of AD was graded. RESULTS: RA was found in 66 cases of AD (36.5%). The average age at onset of asthma was 6 years and the average duration of asthma was 6 years. The average age at onset of allergic rhinitis (AR) was 12.4 years and the average duration of AR was 6.8 years. The prevalence of asthma with AD was the most common in the age group between 8 and 11 years while the prevalence of AR was the most common in the age group between 20 and 23 years. The higher occurrence of RA in the older age group was considered to represent persistence of AD in-to adult life. We could not find any difference in the severity of AD between pure AD patients and AD patients with RA. CONCLUSION: The prevalence of RA in AD in Korea was considered to be similar to that of other reports. The average onset of asthma in Korea was a little later, whereas the average on-set of AR was a little earlier than that in the other reports. The duration of RA, which has hardly been mentioned in the literature, was considered to be about 6 years in Korea. It is likely that RA is a poor prognostic factor for AD, but does not affect severity of dermatitis.

PURPOSE: To evaluate the incidence of disc extrusion and neurologic deficit, the relation between disc extrusion and neurologic deficit and the treatment results according to our basic treatment principles in lower cervical facet joint fracture and dislocations MATERIALS AND METHODS: Twelve patients were evaluated, 8 male and 4 female with an average age of 41 years comprised the group. Six injuries were attributable to automobile accidents, 5 to fall from building, bed, floor and hill, and one to stand on her head. One case was distractive-flexion stage (DFS) 1, 9 cases with DFS 2 and 2 cases with DFS 3. Plain X-ray, CT, Myelo CT and MRI were used as a diagnostic tools. As a treatment criteria, feasibility of closed reduction, status of neuroglogic injury, and stability of injured spine were considered. Anterior cervical discectomy and fusion in accompanied disc extrusion, posterior reduction and fusion with triple wiring in unreduced dislocation, and anterior decompression and fusion in incomplete cord and root injury were selected as a basic treatment principles. RESULTS: Ten out of 12 cases (83%) showed neurologic deficits, 2 complete cord injury, 1 incomplete cord injury, and 7 radiculopathy. Nine out of 12 (75%) demonstrated disc extrusion and all disc extruded patients had neurologic deficits. Anterior cervical discectomy and fusion (ACDF) were performed in 5 cases, ACDF and posterior reduction with triple wiring (PRTW) in 4 cases, PRTW in 1 case, and skull traction and philadelphia brace in 2 cases. Seven radiculpathy patients were completely recovered and one incomplete cord injury patient can ambulate with spastic gait after surgery. There were 2 bed sore and 1 pneumonia in complications. CONCLUSION: Soft disc extrusion should be evaluated carefully with MRI and CT in lower cervical spine injury with the facet joint fracture-dislocations before the decision of treatment. As disc extrusion always accompanies neurologic deficit, it must be surgically treated by anterior cervical discectomy and fusion.

PURPOSE: To evaluate the usefulness, patterns and appearances of false positive lesions, and technical problems of CTAP(CT Arterioportography). MATERIALS AND METHODS: CTAP was done in 45 patients in whom hepatic lesions were suggested on other radiologic studies. CTAP findings were compared with the informations obtained by operations, biopsies, and follow-up imagings. Additional findings, which were not detected in other radiologic studies, false positive manifestations, and technical errors were analyzed. RESULTS: CTAP detected 51 additional hepatic lesions which are not detected in other imaging studies. Of the 51 lesions, ten were true positive hepatic tumors, 2 were inflammatory lesions and 39 were false positive .lesions. False positive lesions included perfusion defects of periportal and perifissural areas, subcapsular perfusion defects and nonlobar, nonsegmental geographic perfusion defects. In 2 cases, CTAP aided in deciding the surgical strategy. On the other hand, there were 4 cases causing interpretational confusion and 6 cases of improper imaging due to technical errors. CONCLUSION: CTAP was valuable in detection of additional hepatic cancer lesion as well as in making the treatment plan. However, since many false positive lesions and improper imaging due to technical error occur during the examination, the understanding of such problems is essential for correct interpretation of CTAP.

As the elderly population increases, they are increasingly affected by oral health problems. Therefore, efforts are being made to improve the oral health of older people, alleviate mental discomfort, and reduce unmet dental needs. This study was conducted to confirm the relationship between the National Health Insurance Elderly Denture Coverage and the unmet dental need for the edentulous elderly, as part of the protection policy. We analyzed the 2011 and 2013 Community Health Survey data of the edentulous elderly, aged 75 years or older, before 2012. In order to more precisely confirm the effects of the denture donation policy on unmet dental care, basic life recipients who were subject to the free elderly prosthetic project were excluded from the analysis. The final analysis included 20,400 subjects. According to our investigation of the factors that affect the unmet dental needs of the elderly, the National Health Insurance Elderly Denture Coverage did not affect unmet dental needs. The statistically significant variables that affected the unmet dental needs of the elderly were education and income levels, which are representative socioeconomic status variables. The lower the level of education, the unhealthier the dental care experience, and income levels showed a similar tendency. The elderly who have a low socioeconomic status are more likely to experience unmet dental needs because they lack the knowledge and socioeconomic ability to pay for dental care. Therefore, the policy for health protection of the entire elderly population should be continuously expanded. In addition, the socioeconomically vulnerable groups may have health problems due to the restriction of medical use, which may lead to quality of life deterioration.

This study investigated the effects of critical thinking and empathy on the cultural competence of dental hygienists and students. A total of 529 dental hygiene students were randomly sampled and included as subjects. PASW Statistics for Windows ver. 18.0 was used to obtain the following results. Among the critical thinking sub-domains, cognitive integration was the highest and the lowest. Empathic ability had the highest acceptance factor among the sub-domains. Cultural competence was the highest among the sub-domains, while cultural knowledge was the lowest. According to their general characteristics, subject age, grade, religion, and economic level influenced the cultural capacity. Cultural awareness and sensitivity were high when there were foreign visiting experiences. Cultural awareness, sensitivity, skills, and knowledge were high when subjects had experienced multicultural education (p < 0.05). Cultural awareness, sensitivity, skill, experience, and knowledge were correlated with critical thinking and cultural competence, among which cultural sensitivity showed the highest correlation (p < 0.001). There was a correlation between cultural awareness and sensitivity, skill, and experience among the empathy and cultural competency sub-domains (p < 0.001). The factors influencing cultural awareness included intellectual integration, openness, prudence, and perspective-taking (p < 0.001). The factors influencing cultural sensitivity included intellectual integration, openness, and empathic concern (p < 0.001). The factors influencing cultural skill included intellectual integration, creativity, and conductivity (p < 0.001). The factors influencing cultural experience included prudence, objectivity, perspective-taking, and personal distress (p < 0.001). Finally, the factors influencing cultural knowledge included creativity and conductivity (p < 0.001). The results indicate that dental hygiene students should be equipped with cultural competence to enhance critical thinking and empathy required by the modern society and optimized dental hygiene courses should be provided for multicultural subjects.

Background: The purpose of this study is to identify the gender sensitivity and gender role stereotypes of students in dental hygiene and to provide basic data to expand social awareness of equal gender sensitivity and gender role in dental hygiene and students by identifying the degree of correlation. Methods: The purpose of this study was to study dental hygiene students at colleges in Gyeonggi and Chungcheong areas. The survey was conducted from April 1 to April 30, 2021. The final sample was analyzed on 157 subjects. T-test and ANOVA analysis were performed to compare gender sensitivity and gender role stereotypes according to general characteristics. Equal variances were tested using the Levene statistic, and significant differences between groups were identified through Scheffe’s post hoc analysis. Pearson’s correlation analysis was performed to confirm the correlation between gender sensitivity and gender role stereotypes. Results: Gender sensitivity was 2.69 and gender role stereotypes were 1.83. Among the sub-areas of gender sensitivity, gender role openness was the highest at 2.86, and non-violence was the lowest at 2.50. As for gender role stereotypes, social stereotypes were the highest among sub-areas at 1.71. Among the general characteristics, there was a statistically significant difference in gender sensitivity according to the presence or absence of opposite sex friends (p=0.011). The gender identity openness of gender sensitivity and the physical sub-areas of gender role stereotypes showed the highest positive correlation(r=0.955). Among the sub-areas of gender sensitivity, gender role openness and domestic stereotypes showed the lowest negative correlation (r=−0.404) among the sub-areas of gender role stereotypes. Conclusion Dental hygiene students should be able to critically analyze and solve problems of not only sexual violence but also gender discrimination and imbalance in social life. For this, environmental factors such as school education and professor guidance must be strengthened.

Background: Maintaining a skilled workforce by minimizing the turnover of competent dental hygienists is very important for securing dental competitiveness. Therefore, it is necessary to find a predictor of turnover and lower turnover intention. To understand dental hygienist turnover, it is necessary to study the resilience, a positive factor of personal characteristics and job embeddedness that induces residual tissue. The purpose of this study was to investigate the effect of dental hygienists’ job embeddedness and resilience on turnover intention. Methods: A survey was conducted on licensed dental hygienists nationwide, from March 19 to July 19, 2020. T-test and one way ANOVA analysis were performed to compare the job embeddedness, resilience, and turnover intention according to the general characteristics. Pearson’s correlation analysis was performed to identify the correlation between job embeddedness, resilience, and turnover intention. Multiple regression analysis was performed to determine the effect on the turnover intention. Results: Job embeddedness was the highest with link and resilience scoring 3.57 and 4.16, respectively. The turnover intention scored 3.53. Among the general characteristics, age, marriage, total dental clinic career, education degree, and position showed statistically significant differences in job embeddedness, resilience, and turnover intention. Suitability, link, and sacrifice of job embeddedness were shown to affect the degree of turnover intention, with an explanatory power of 26.2%. Conclusion In order to reduce the dental hygienists’ turnover intention, job embeddedness and resilience should be increased.Thus, measures should be undertaken for professional and systematic program development and human resources management.
