Suggestion of Learning Objectives in Social Dental Hygiene: Oral Health Administration Area / 치위생과학회지

The purpose of this study is to propose learning objectives in social dental hygiene by analyzing and reviewing learning objectives in oral health administration area of the existing public oral health. This study is a cross-sectional study. The subjects of the study selected with convenience extraction were 15 members of the social dental hygiene subcommittee of the Korean Society of Dental Hygiene Science. Data collection was conducted by self-filling questionnaire. The research tool is from 48 items of A division in the book of learning objectives in the dental hygienist national examination, and this study classified each of them into ‘dental hygiene job relevance’, ‘dental hygiene competency relevance’, ‘timeliness’, and ‘value discrimination of educational goal setting’ to comprise 192 items. Also, to collect expert opinions, this study conducted Delphi survey on 7 academic experts. Statistical analysis was performed using the IBM SPSS Statistics ver. 23.0 program (IBM Co., Armonk, NY, USA). Recoding was performed according to the degree of relevance of each learning objective and frequency analysis was performed. This study removed 18 items from the whole learning objectives in the dental hygienist national examination in the oral health administration area of public oral health. Fifteen revisions were made and 15 existing learning objectives were maintained. Forty-five learning objectives were proposed as new social dental hygiene learning objectives. The topics of learning objectives are divided into social security and medical assistance, oral health care system, oral health administration, and oral health policy. As a result of this study, it was necessary to construct the learning objectives of social dental hygiene in response to changing situation at the time. The contents of education should be revised in order of revision of learning objectives, development of competency, development of learning materials, and national examination.

Dental Hygienist-Led Dental Hygiene Process of Care for Self-Support Program Participants in Gangneung / 치위생과학회지

This study aimed to provide basic data for establishing the clinical basis for dental hygienist-led dental hygiene process of care by identifying multiple risk factors for self-support program participants in Gangneung city; we also compared oral health status and behavioral changes through customized oral health care. Four dental hygienists who were evaluated for degree of conformity provided dental hygiene process of care to eight self-support program participants who were selected as having an oral health risk among people in the self-support center. The clinical indicators measured during dental hygiene assessment and evaluation and behavioral changes due to dental hygiene intervention were compared and analyzed. With respect to clinical indicators, at the time of probe, the retention rate of patients with gingival bleeding decreased from 61.4% to 14.7% after intervention (p=0.004). Furthermore, the retention rate of patients with a periodontal pocket >4 mm decreased from 15.6% to 5.8% (p=0.001). The average modified O'Leary index of the patients improved from 23 to 40 (p=0.002). Previously, all eight subjects used the vertical or horizontal method of brushing; after dental hygiene care interventions regarding method and frequency of toothbrushing, use of oral care products, and individual interventions, they started using the rolling or Bass method of toothbrushing. Four of eight subjects reported using interdental toothbrushes after intervention. As a result of applying the change model to the transtheoretical behavior change of the subject, the result of strengthening the health behavior was confirmed. For promotion of oral health by the prevention-centered incremental oral health care system, dental hygienist-led dental hygiene management and maintenance is essential. It is thought that continuous research, such as for feasibility evaluation, cost benefit analysis, and preparation of legal systems, is needed to establish and activate dental hygiene management.

Evaluation of Project-Based Learning on Community Dental Hygiene Practice Education / 치위생과학회지

The purpose of this study was to evaluate community dental hygiene practice education, by verifying its effect after applying project-based learning in improving the practical and social skills of learners. A 15-week project-based community dental hygiene practice course was held for 27 senior students, who took community dental hygiene practice course in the Department of Dental Hygiene, Gangneung-Wonju National University. Twenty-seven students were composed of 4 teams. Each team selected a target group for four workplaces for adult workers to apply the oral health promotion project. The project was then planned and conducted based on a survey on the health problems confronting each group, and an evaluation was carried out after 4 weeks. From the results obtained in comparing confidence in problem solving ability, project value, teamwork competency, and community dental hygienist competence before and after course, the improvement in project value and teamwork competence scores was not statistically significant, but all four areas showed positive results. After analyzing the project actuality, learning outcomes, and project satisfaction after course results, the actuality of the project was 19.30 points, the learning achievement was 45.19 points, and the satisfaction was 19.19 points, demonstrating that the aim of achieving actual performance competence and a learning performance exceeding expectations was accomplished. After conducting an interview survey with 8 students, it was found that they had learned social skills involving problem-solving abilities and confidence, and teamwork competence such as cooperation, role responsibility, creative thinking ability, and communication skills. Community dental hygienists should be able to acquire learner-level practical skills and social skills in the community dental hygiene and practical courses, according to their competencies and job needs. It is necessary to develop a project-based systematic learning module to enable the community dental hygiene practice to operate as a subject closely related to fields in other dental hygiene departments.

Evaluation of Oral Health Promotion Program Connected with Hypertension and Diabetes Management Programs: Use of a Logical Model / 치위생과학회지

This study aimed to design and operate a complementary integrated health management program based on the connection between the hypertension and diabetes management programs and the oral health programs at a public health center. It also proposed to suggest the phased evaluation indicators. In this study, 48 adults registered in the hypertension and diabetes management program were selected from the Gangneung public health center. The clinic-specific programs were led by dental hygienists and operated for visitors twice every two weeks. The programs were designed based on the logical model, and indicators for evaluating the structure, process, and outcome were presented and applied to the input, process, output, and outcome. The evaluation indices consisted of quantitative and qualitative indicators, and the planning and operation, goal achievement, and effect of each program were assessed. The process evaluations were assessed by the appropriateness of the managers and the operating fidelity of the programs. Indicators for evaluating the outcomes were gingival bleeding, oral health knowledge, oral health awareness, and the satisfaction of the participant and the manager. The clinic-specific programs resulted in positive changes in the evaluated outcomes. The integrated health management of visitors to the hypertension and diabetes management program is important as the general and oral health has common risk factors. Furthermore, long-term operation and continuous monitoring of oral health programs are necessary to evaluate the common factors in chronic disease management.

Oral Health and Occupational Status among Korean Adults / 치위생과학회지

The purpose of this study was to determine the oral health condition and behavioral status of Korean adults according to occupational status. The subjects were 7,676 adults, aged between 19 and 64 years, who completed both oral examination and questionnaire survey, among those who indicated that they were currently participating in economic activities, according to the data from the Fourth Korea National Health and Nutrition Examination Survey. Occupational class and employment status were selected as measures of occupational status. Complex-samples logistic regression models were used to assess the associations among oral health, behavioral, and occupational statuses. We found a significant occupational class-related difference in the oral health and behavioral statuses of both the men and women. In particular, the prevalence odds ratios of untreated dental caries in manual workers were 1.19 and 1.67 times higher than in non-manual workers, for men and women, respectively. As for oral health condition and behavioral status according to employment status, the health risk in temporary employment workers was higher than that in permanent employment workers. As for the prevalence odds ratios of the risk of dental caries, the highest values were observed for tooth brushing fewer than 3 times per day, not undergoing oral examinations, and chewing difficulty complaints. The risk of dental caries for agricultural, forestry, and fishing workers for both men and women was found to be the highest among other workers. Thus, strategies to promote workplace oral health in the microscopic and macroscopic perspectives should be developed to constantly monitor oral health problems, and to identify vulnerable social groups within occupational groups and the related factors that mediate oral health differences.

Two Cases of Nerve Sheath Myxomas

Nerve sheath myxoma(NSM) is a rare cutaneous neoplasm of uncertain histogenesis. NSM can be divided into two groups; NSM1 (a myxoid NSM) and NSM2 (a cellular neurothekeoma). NSMs are characterized histologically by well-defined, lobular or plexiform dermal proliferation of stellate, spindle-shaped cells embedded in abundant myxoid stroma. A variable amount of nerve fascicles are entrapped within and around the tumor. Two variants of NSM share the same features to a certain degree but differ in cellularity and mucin deposition. We report two cases of NSMs with different clinical and histopathologic features.

Effect of serotonin uptake inhibitors on serotonin metabolism in the hypothalamus of freely moving rats

Tricyclic antidepressant clomipramine or selective serotonin reuptake inhibitors (SSRIs) have been commonly used for the treatment of premature ejaculation. In the present study, we analyzed the concentrations of serotonin and 5-hydroxyindoleacetic acid (5-HIAA) in the medial preoptic area (MPOA) of the hypothalamus by awakening animal microdialysis following administration of clomipramine and various SSRIs. We then compared the serotonin metabolism and clinical effects of clomipramine and SSRIs on premature ejaculation. Basal extracellular serotonin level in the MPOA was higher than other brain regions and it was significantly increased by clomipramine and the SSRIs. The rank order of the concentration of serotonin at the MPOA was clomipramine, sertraline, paroxetine and fluoxetine and the concentrations of 5-HIAA was vice versa. The changes in serotonin concentration at the MPOA appeared closely associated with the clinical effects of these drugs on premature ejaculation. These results suggest that the serotonergic neuronal activity in the MPOA may have an selective inhibitory influence on ejaculation, and the effects of clomipramine and SSRIs on erectile function are mainly mediated by MPOA of the hypothalamus.

The effect of indomethacin on the production of eicosanoids and edema during ischemia-reperfusion injury in skeletal muscle

During reperfusion of skeletal muscle after ischemia, lipid mediators, mainly eicosanoids, are released and may have a role in the pathogenesis of reperfusion injury. To validate the role of eicosanoids in the ischemia-reperfusion induced functional deficits in skeletal muscle, we compared muscle edema and the changes of eicosanoid concentration in the rat hind limb after ischemia-reperfusion injury by application of tourniquet. After 4 hours of ischemia, reperfusion was established for 4 hours by releasing tourniquet. To assess tissue damage, edema, and wet/dry weight ratios were determined and the eicosanoid concnentrations were measured by the HPLC. The muscle edema and the release of cyclooxygenase metabolites were not induced by the ischemia itself rather they were significantly increased by reperfusion. Indomethacin treatment ameliorated limb edema and decreased the release of 6-keto-PGF1alpha, thromboxane B2, and PGE2 induced by reperfusion. But the inhibitory effect of indomethacin on edema (35%) was relatively low than the inhibitory effect on release of cyclooxygenase metabolites (up to 69%) by reperfusion. These results support the view that cyclooxygenase products may play a significant role in the formation of muscle injury by ischemia-reperfusion and suggest that nonsteroidal antiinflammatory agents might be partially beneficial to the management of acute limb ischemia-reperfusion injury.

Two Cases of Cement Burn

Wet cement can cause caustic ulcers due to its alkalinity. Besides caustic ulcers frequently called cement burn, allergic and irritant contact dermatitides are common in cement workers. Alkalinity of calcium hydroxide in wet cement combined with the effect of pressure and occlusion against skin may result in cement burn. We report two cases of cement burn due to their occupational exposures.

A Case of Chronic Bullous Dermatosis of Childhood: Implication for Duration of Dapsone Maintenance Therapy / 대한피부과학회지

Chronic bullous dermatosis of childhood(CBDC) is a rare vesicobullous disorder in infancy and early childhood. The direct immunofluorescence(DIF) study is mandatory for diagnosis because its clinical and histological findings may be indistinguishable from those of bullous pemphigoid and dermatitis herpetiformis. The response to sulfonamides such as dapsone and sulfapyridine is usually rapid and complete. After remission of the disease, however, it is difficult to predict the course of the disease and to decide when treatment should be stopped. We report a case of CBDC in a 2-year-old boy. Treatment was started with dapsone and complete resolution of lesions was achieved in 2 weeks. The entire regimen was continued for 6 months and the patient has been clinically free of disease activity after 18 months of follow-up.

Nonpigmenting Fixed Drug Eruption to Etodolac / 대한피부과학회지

Nonpigmenting fixed drug eruption is a form of fixed drug eruption which heals without pigmentation. To leave no traces makes the diagnosis difficult. A 37-year-old man pressented the erythematous patches on both wrists and the left thigh. Several hours before the eruption, he had taken oral drugs for the treatment of osteomyelitis. He had had the same eruptions which were diagnosed as an allergic contact dermatitis, 8 months ago. The patch tests with medicated drugs were negative, but oral provocation with etodolac brought the same eruptions.

Two Cases of Allergic Contact Dermatitis to Povidone-iodine / 대한피부과학회지

Povidone-iodine(PVP-I) is a widely used antiseptic for the skin because of its low toxicity and high germieidal efficacy, Allergic contact dermatitis to PVP-I is known to be rare. Two patients who recently underwent surgical operations were referred to us due to pruritic well-demarcated eczematous skin lesions around the wounds. Their operation wounds had persisted in spite of the treatments using systemic antibiotics and topical antiseptics. Patch tests were performed with antiseptics including PVP-I, hydrogen peroxide, and benzalkonium chloride which had been used to dress their wounds. The patch tests resulted in positive reactions to PVP-I at the concentrations of 1% in one patient and 0.01% in another.

A Clinical Study of the Recurrence in Primary Pterygia

We made the clinical evaluation of the 110 primary pterygia which were excised according to D'ombrain bare sclera method and modified Bangerter method at Chunchon Sacred Heart Hospital from May of 1985 to April of 1987. The followup period ranged from 3 months to 12 months(average: 6 months). The results were as follows: 1. The total recurrence rate was 7.3%. 2. The bilaterality in recurrent group was 62.5%, whereas was 34.3% in nonrecurrent group(p<0.05). 3. The number of vessels(from the base of pterygium toward apex) in recurrent group was 27-35(average: 30.6 +/- 2.6), whereas was 8-32(average: 20.5 +/- 6.1) in non-recurrent group(p<0.05). 4. The incidence of the previous recurrent history of the other eye in recurrent group was 37.5%, whereas was 3.9% in non-recurrent group(p<0.05). 5. The recurrence rate in modified Bangerter method group was 1.6%, whereas was 15.2% in D'ombrain bare sclera method group(p<0.05) and the modified Bangerter method group gave very good esthetic results.
