The author herein presents an unusual case of eustachian tube calcification masquerading as loose radiopacities in the temporomandibular joints on a panoramic image, creating a diagnostic challenge. The patient, a 72-year-old woman, presented to the dental service for implant treatment to improve her masticatory function. A cone-beam computed tomography scan was performed and reviewed by a board-certified oral and maxillofacial radiologist. The scan showed no evidence of calcifications in the temporomandibular joints; however, it revealed nodular calcifications within the cartilaginous portion of the eustachian tube bilaterally. Additionally, this report briefly reviews the differential diagnosis of calcified loose bodies in the temporomandibular joint and provides information that needs to be reinforced periodically.

Objectives: This study is designed to suggest the health service goals necessary for providing the more efficient services relevant to the requests of the community, through the evaluation on the operating status of the unified health subcenters. Methods: We visited total 5 unified health subcenters comprising 3 ones located in Gyeongsangbuk-do and 2 ones located in Gyeongsangnam-do from December 2000 to January 2001, and interviewed about the pre- and post-unified status related to manpower, facilities, equipment, medical service and health service quality, and the problems and improvement plans of the unified management. Results: According to the evaluation on the manpower before and after the unification of the health subcenters, the total employees increased by 2.8 persons on average from 6.8 to 9.6 persons in the investigated subjects. The numbers of doctors, dentists and nurses were almost the same as before. There were no clinical pathologic technician and radiological technician before but they were appointed to duty in 3 unified health subcenters later. The unification of the health subcenters has produced slight increases in the frequency of the medical service and dental treatment and considerable increases in that of the physical therapy and laboratory tests. In relating to the changes of the health service, the cases of visiting health care and ambulatory medical service, and the total number of health education participants were greatly increased after the unification. The number of cases undergoing the vaccination and cervical cancer screening was similar to that of the pre-unification while the patient number of the registration to hypertension or diabetes showed a tendency to increase a little. Since the unification of the health subcenters, the frequency of laboratory tests has been increased, but the quality of health service has not been improved yet. Nevertheless, the unification seems to be positive according to the result of the great improvement in visiting health care, ambulatory medical service and health education service. The problems of the unification of the health subcenters were indicated in indefiniteness of the service details between the workers; excessively large building hard to be effectively managed; insufficient medical instruments, inappropriation of working expenses, lack of professional training for the health education, etc. Conclusions: For further active functions of the unified health subcenters, the minimal allocation basis to appoint doctors, nurses and administrative workers to do the duty should be differentiated from the basis for a health subcenter, and the fundamental instruments needs to be expanded to improve the quality of the medical service and visiting health care service. Moreover, the unified health subcenter needs to have definite service details between the workers, and should improve the working efficiency through the development of service-related guidelines.

Purpose: Through a thorough examination of the CCSC (Community Comprehensive Support Center) system in Japan, this study suggests a scheme to provide community-based preventive health care services for the elderly in Korea. Methods: The study inquired into the applicability of the Japanese model by reviewing the data related to the CCSC project, aided by both in-depth interviews with staff in the field and consultations with specialists. Results: Rearrangement of the Visiting Health Management Project system is needed to manage the collective or individual visiting care management for frailty prevention of the elderly in communities. The delegated service system for preventive care in the community, including direct management by one of the public health centers, also needs to be reviewed and the application of stricter standards for the selection of the agency or corporation to run the delegated service is necessary. Long-Term Care Insurance, along with national and local grants, is to be considered as a financial resource for the community-based preventive health care model for the elderly. By making active use of education rooms at district offices, senior citizen centers in neighborhoods for the elderly with easy access can be created. The project needs to raise active supports from communities, develop programs which can be absorbed into particular local cultures, and promote the understanding of the preventive project in local communities. The preventive program should focus on first solving the problems of depression, seclusion, and lack of mobility of the elderly. Second, the program should instruct physical self-management for exercise-nutrition-dental maintenance, and third, the program should strengthen the cognitive abilities of the elderly. In addition, it is necessary to systematize and implement counter-plans of the family and community to protect the elderly who has mental and cognitive problems. Finally, by establishing a network of public health welfare resources based upon research on a community level, assessment and planning for the health of the elderly should be one with their family, and comprehensive consultation and recommendations should be provided to the family. Conclusion: Taking into consideration the experience Japan has had with respect to a similar project, it is appropriate to develop and implement a service system which would combine the Visiting Health Management Project system which has already been established and a preventive health care model for the elderly on a community level.

This study was carried out to find out the basic data required to plan and develop Rehabilitation Day Care Program for the stroke survivor's family in Korea. The subjects comprised of 92 stroke survivor's family who discharged from 4 hospitals in Seoul during the past 2 years. The data were collected from August 3, 1998 to September 18, 1998, through interviews with questionnaires about general characteristics, activities of daily living, depression and service need of rehabilitation day care program at the outpatient clinics by trained nursing graduates. Data were analyzed with descriptive analysis, Pearson's correlation analysis, and Stepwise multiple linear regression analysis using SPSS/WIN 10.0 program. The results obtained are as follows; 1. The mean score of the general need of rehabilitation day care program of stroke survivor's family was 3.10(range 1-4). The highest need among the service categories of the rehabilitation day card program was self-care and restorative activities category(3.30), and health services referral category, recreation category, psychosocial activities category in order. The needs of each category are as follows. In the health services referral category, the need for dental examination and medical examination were highest, followed by the need for physical therapy and occupational therapy. In the psychosocial activities category, the need for family counselling was highest. In the self-care and restorative activities category, the need for ROM exercise training was highest, followed by bowel training, and ambulation training. 2. The need of family for rehabilitation day care program service displayed a correlation with the level of education, ADL, and the level of depression, and a reverse correlation with age, illness intrusiveness, depression, knowledge, subject and object burden and relationship with stroke survivors. 3. The stepwise multiple linear regression analysis revealed following results. For the need for rehabilitation day care program service, 22.6% of the variance was initially explained by level of family's knowledge about caring method for stroke survivors, 8.8% was the level of subjective burden and 5.4% was relationship with stroke survivors. In conclusion, above characteristics should be considered to develop stroke survivors' rehabilitation day care program.

Background: The efforts to build more "people centered," "patient centered" health system has been emerging all over the world. Aligning with it, the Korean government is conducing the survey called "Medical Service Experience Survey (MSES)." There are critics, however, that MSES is not scrutinizing the medical experiences of patients in various healthcare settings. For this reason, this study aims to perform an empirical analysis of the differences in answers of patients responding to various healthcare settings. Methods: There are two steps in this study. First, explanatory analysis is conducted to compare the tendency of statistical concentration on questionnaires by divided healthcare settings. Second, confirmative analysis is carried out to evaluate the construct validity, reliability, and discriminant validity of the questionnaire in each healthcare setting. The raw data of MSES, which was conducted in 2020 by the Ministry of Health and Welfare in Korea and the Korean Institute for Health and Social Affairs is used. Results: As a result of exploratory factor analysis for all outpatients, the items were classified into four factors statistically: "doctor experience," "nurse experience," "outpatient service experience," and "patient satisfaction." It was confirmed that the reliability of all factors extracted was secured. However, for patients who visited hospitals, questionnaires related to personal privacy, such as "experiences on medical staffs considering physical exposure" or "experiences related to personal information exposure," were answered in conjunction with items of "nurse experience." Besides, patients responded that administrative elements of medical services, such as "experiences of comfort in medical institutions" and "experiences of satisfactory administrative services," were related to the items of "nurse experience." The answers of patients who visited traditional medical hospitals and clinics about "doctor experience" and "nurse experience" were not discerned statistically, and the answers to "doctor experience," "nurse experience," and "medical institution experience" were entangled with the responses of patients who visited dental hospitals and clinics. On the other hand, as a result of the confirmatory factor analysis, it was found that the inquiries of MSES generally had intensive validity. Conclusion: The collection of objective and scientific data is the prominent component to enlighten the patient-centered healthcare system alongside with change of the worldwide paradigm of measuring the healthcare system performance as follows the transition of perspective of health care from provider-centered to patient-centered. This study empirically shows that the patient experience can vary as the healthcare settings. Furthermore, to make an advance in measuring the experience of patients with medical services, this article proposes the deliberate consideration of the different kinds of healthcare settings and articulate design of the survey.

Background: The objective of this retrospective study was to show results from platform-switched narrow-diameter implants in the posterior edentulous region, which we followed up for more than 1 year after functional loading. Methods: Ninety-eight narrow implants were inserted into 66 patients. After healing, fixed implant-supported prostheses were delivered to the patients, and Periotest and radiographic examinations were performed. After the first year of loading, the implant outcome was again evaluated clinically and radiographically using the Periotest analysis. Crestal bone loss and Periotest values (PTVs) were used to evaluate the effect of surgery, prosthesis, implant, and a host-related factor. A general linear model was used to statistically detect variables statistically associated with crestal bone loss and Periotest value. Results: We followed up on the implants over 1 to 4 years after loading; their survival rate was 100 %, and pronounced differences from PTVs were noted among jaw location, bone quality, and loading period. No difference was detected in bone loss among the variables studied. Bone loss after functional loading was $0.14{\pm}0.39mm$. The stability value from the Periotest was $-3.29{\pm}0.50$. Conclusions: Within the limitations of this study, judicious use of platform-switched narrow implants with a conical connection must be considered an alternative for wide-diameter implants to restore a posterior edentulous region.

Background/Purpose: The purpose of this study was to evaluate the effect of Nd:YAG irradiation on adherence of retrograde filling materials (mineral trioxide aggregate [MTA] and Super-EBA) by micro-computed tomography (CT) measurement and to observe the dentinal surface after irradiation by scanning electron microscopy (SEM). Materials and methods: Forty retrofilling models using extracted human teeth were divided into four groups according to the material and method used: ProRoot MTA (MTA group), Super-EBA (EBA group), MTA with Nd:YAG laser irradiation (LMTA group), and Super-EBA with Nd:YAG laser irradiation (LEBA group). All specimens were stored in 100% humidity for 24 hours until micro-CT was performed. The gap volume of the tooth/material interface was measured using the CTAn program. In six samples, the laser-irradiated dentin surface was observed using SEM. Results: The mean percent difference in gap volume was not statistically significant between the Nd:YAG laser-irradiated groups and non-irradiated in both materials(P > 0.05). The gap volume in the MTA group was significantly lower than that in the EBA group (P < 0.05). Examination of the non-irradiated specimens by SEM showed patent dentinal tubules. In contrast, alterations in the texture of the dentin surface and obliteration of the dentinal tubules were evident in the Nd:YAG laser-irradiated specimens. Conclusion: In this study, changes in the dentinal surface after Nd:YAG irradiation did not affect adherence between the apical filling material and the dentin wall.

Purpose: The purpose of this study was to investigate the relationship between periodontal disease, diabetes and chewing problems in Korean adults over the age of 19 using the 6th National Health Nutrition Survey. Methods: Data from the 6th National Health and Nutrition Survey (Ministry of Health & Welfare, 2013; 2014; 2015) were used. In this study, 17,101 adults aged 19 and older were included in the study to determine the relationship between diabetes and chewing problems in Korean adults. Results: Diabetes and chewing problems have been associated with periodontal disease. Diabetes was 0.719 times lower(p<0.001) in periodontal disease than in the case of diabetes. Chewing problem was 1.360 times(p<0.001) periodontal disease prevalence compared to 'not at all uncomfortable'. It was found that the prevalence of periodontal disease was 2.139 times(p<0.001) compared to 'not at all uncomfortable'. It was found that the prevalence of periodontal disease was 2.296 times higher(p<0.001) compared to 'not at all uncomfortable'. It was found that the prevalence of periodontal disease was 2.119 times higher(p<0.001) compared to 'not at all uncomfortable'. Conclusion: Diabetes and chewing problems were found to be related to periodontal disease, and as reported in previous studies, diabetes and chewing problems related to oral disease need to be prevented and treated with regular checkups. In addition, based on the research results, it can be used as basic data for the health business plan that can maintain and manage health.

Objective : Propofol and volatile anesthesia have been associated with metabolic acidosis induced by increased lactate. This study was designed to evaluate changes in pH, base excess (BE), and lactate in response to different anesthetic agents and to characterize propofol infusion-associated lactic acidosis. Methods : The medical records of patients undergoing neurosurgical anesthesia between January 2005 and September 2012 were examined. Patients were divided into 2 groups : those who received propofol (total intravenous anesthesia, TIVA) and those who received sevoflurane (balanced inhalation anesthesia, BIA) anesthesia. Propensity analysis was performed (1 : 1 match, n=47), and the characteristics of the patients who developed severe acidosis were recorded. Results : In the matched TIVA and BIA groups, the incidence of metabolic acidosis (11% vs. 13%, p=1) and base excess (p>0.05) were similar. All patients in the TIVA group who developed severe acidosis did so within 4 hours of the initiation of propofol infusion, and these patients improved when propofol was discontinued. Conclusions : The incidence of metabolic acidosis was similar during neurosurgical anesthesia with propofol or sevoflurane. In addition, severe acidosis associated with propofol infusion appears to be reversible when propofol is discontinued.
