The aims of this study were to investigate whether the facial skeletal patterns previously reported to be related to temporomandibular disorder (TMD) in other studies could be consistently observed in the TMD patients diagnosed according to Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD) Axis I and evaluate its usability in the orthodontic clinics to examine the patients with TMD related symptoms. The clinical records and radiographs of female patients who visited the TMD and Orofacial Pain Clinic of Seoul National University Dental Hospital and were diagnosed as TMD were consecutively filed for this study. Patients were clinically examined and diagnosed according to the revised diagnostic algorithms of RDC/TMD Axis I and the lateral cephalogram, panoramic orthopantomogram, temporomandibular joint (TMJ) orthopantomogram, and transcranial radiograph of each patient were taken and digitalized. The data of patients who were under 18 years of age or had any systemic disease, trauma history involving the TMJ, or skeletal deformity at the time of the first examination were excluded. The remaining data of 96 female patients were finally analyzed. The obtained results were as follows: 1. There are no significant differences of cephalometric measurements between RDC I (muscle disorders) diagnostic groups. 2. Only the articular angle of the RDC group IIc (disk displacement without reduction without limited opening) patients was larger than patients of the no diagnosis of RDC II group (disk displacement). 3. Larger articular angle and smaller facial height ratio were observed in RDC IIIc group (osteoarthrosis) compared to IIIa group (arthralgia). Larger articular angle, larger Bjork sum, smaller posterior facial height, and smaller facial height ratio were observed in RDC group IIIc compared to no diagnosis of RDC III group (arthralgia, arthritis, and arthrosis). 4. According to the results of cephalometric analysis in simplified RDC groups, smaller overjet was observed in muscle disorders (MD) group. Facial height ratio and IMPA were smaller and articular angle was larger in disk displacements (DD) group than in no diagnosis of DD group. In arthrosis (AR) group, posterior facial height, and facial height ratio were smaller, and articular angle, gonial angle, facial convexity, FMA, Bjork sum, and ANB were larger than in no diagnosis of AR group. In joint pain (JP) group, only posterior facial height was smaller than no diagnosis of JP group. In conclusion, Facial morphologic patterns showing posterior-rotated mandible and lower posterior facial height is related to RDC group II and III diagnosis of the TMJ in female TMD patients. RDC/TMD Axis I diagnosis can provide a good clinical diagnostic tool for the standardized examination of the TMJ in orthodontic clinics.

Purpose: This study was performed to assess the lifestyle-related behaviors of patients with gastric cancer (GC) and to investigate the associations between the time since GC diagnosis and these behaviors. Materials and Methods: This study included 29,478 adults (including 338 patients with GC) aged ≥ 40 years who participated in the Korea National Health and Nutrition Examination Survey 2014-2021. Multiple logistic regression analysis explored the associations between the time since GC diagnosis (patients diagnosed with GC less than 5 years ago [<5 years group] and those diagnosed with GC 5 or more than years ago [≥5 years group]) and lifestyle factors. Subgroup analyses were conducted based on age and sex. Results: The current smoking rate was not lower in the GC group than in the healthy group, regardless of time since diagnosis. Compared to the healthy controls, monthly alcohol intake was lower in the <5 years group (odds ratio [OR], 0.450; 95% confidence interval [CI], 0.275-0.736). The ≥5 years group showed a lower rate of strength training (OR, 0.548; CI, 0.359-0.838), compared with the healthy control group. Subgroup analysis focusing on the ≥5 years group revealed a significantly lower rate of strength training, particularly in patients aged ≥65 years and male patients (OR, 0.519 and 0.553; CI, 0.302-0.890 and 0.340-0.901, respectively). Conclusions: Clinicians should continue educating patients on lifestyle behavior modifications, particularly alcohol abstinence, even beyond 5 years after GC diagnosis. Education on strength training is especially important for patients ≥65 years or male patients.

Objectives : The purpose of this study is to examine the general personality profiles of patients who visited an oriental neuropsychiatric clinic and to investigate the specific profiles of patients diagnosed with Hwa-byung. Methods : We analyzed the profiles of 122 patients who completed TCI-RS questionnaire for the purpose of counseling. Patients were divided by sex, age and diagnosis related groups. Scales and subscales of each group were compared by an independent t-test and ANCOVA with SPSS windows 16.0. Types of temperament and character were classified by percentile ranks of the total patients and diagnosis related groups. Results : 1. Total patients were classified as the high harm avoidance type of temperament and of low self-directedness type of character. 2. Male patients showed significantly higher scores on NS, all subscales of NS, P2 and P3 than female patients. HA4 and C5 scores were significantly higher in the female group. Younger patients showed significantly higher scores on NS, all subscales of NS, HA1 and P3. However, older patients had significantly higher scores on SD4, SD5, ST2 and ST3. 3. Between diagnosis related groups, Hwa-byung group had significantly higher scores on RD, ST, SD3 and ST2. However P3 score of non-hwa-byung patients was higher than hwa-byung patients. In typical classification, both hwa-byung and non-hwa-byung groups were classified as the same types as total patients. Conclusions : This study showed that the patients visited an oriental neuropsychiatric clinic and had similar personality with that of general psychiatric disorders. Hwa-byung patients exhibited higher RD and ST scores than other disorders, but they had no typical differences.

Background: Engaging and Involving stakeholders who have different interests in changing health care policies are difficult task. As the literature on the governance in Korean health care field is rare, this study aims to provide empirical evidence of 'governing health policy'-the ways health care policy is made, implemented, and evaluated from a political perspective. Methods: The authors of this study conducted interviews with elites in policy and clinical areas, which was considered to be the most effective approach to gather in-depth information about the background of changing payment policy as well as the barriers or contributors for making the policy sustainable. A total of 14 experts (3 government officials, 2 representatives from medical profession, 3 professors form academic field, and 6 healthcare providers from New DRG pilot program hospitals) participated in 2 hour long interviews. Results: There was a perception gap of the feasibility and substantiality of new payment system among elites. The score was higher in government officers than those in scholars or clinical experts. Next, the interviewees indicated that Korean New DRG might not sustain without significant efforts to improving democratic aspects of the governance. It is also notable that all interviewees except healthcare providers provided negative expectation of the contribution of new payment system to increase administration efficiency. For clinical efficiency, every stakeholders perceived there was no increased efficiency after introduction of New DRG payment. Like general perception, there was a wide gap between the perception of stakeholders in quality change after implementing the new payment system. Finally, interview participants negatively assumed about the likelihood of New DRG to remain a case of successful reforms. Conclusion: This study implied the importance of social consensus and the governance of health policy.

Purpose: The aim of this study was to investigate the changes in perception of the New Diagnosis-Related Group (DRG)-based payment system, make overall evaluation after participation, and examine opinions on further policy improvement among employees of a public hospital participating in the pilot project in Korea. Methods: We investigated changes in perception of the New DRG-based payment system before and after participation in the pilot project using a qualitative research method. We conducted individual in-depth interviews with the management and healthcare professionals and Focus Group Interviews (FGIs) with the staff in the nursing and administrative departments. Results: Before implementing the pilot project of the New DRG-based payment system, the management was in favor of participating in the pilot project, whereas the healthcare professionals were strongly opposed to participation in the pilot project, and the staff in the nursing and administrative departments were slightly opposed to participation. After implementing the pilot project, there were remarkable changes in the perception of the New DRG-based payment system among healthcare professionals and the administrative staff. Healthcare professionals' perception was altered in a positive way, while the administrative staff's perception of the system became negative. Conclusion: There were no restrictions on clinical practice or deterioration of quality of care observed in association with the participation in the New DRG-based payment system. However, certain unintended consequences of the New DRG-based payment system may arise as well. Therefore, the government needs to examine the problems identified in this study to reflect on and improve the New DRG-based payment system for stable expansion.

Objectives: Since early developed measurement of Postpartum depression(PPD) doesn't reflect physical symptoms, we need to find out how PPD and related physical disorders are expressed in functional medical methods. The study was conducted to find out characteristics of 7 Zone diagnosis and postpartum physical symptoms on PPD. Methods: To 216 postpartum women who did normal delivery, we measured 7-zone-diagnosis Factor AA's height on 5th day and 15th day postpartum. And we surveyed EPDS and postpartum physical symptoms question on 15th day postpartum. Subjects were divided into normal and depression group by EPDS score. And we compared Factor AA's height between two groups and Factor AA's height change in each group. Results: In depression group, Factor AA's height was higher than normal group on 5th day and 15th day postpartum. In both groups Factor AA's height was decreased on 15th day compared to 5th day postpartum. In normal group 2, 6, 7 zone were significantly decreased and in depression group only 6 zone was significantly decreased. Conclusions: These results demonstrate that postpartum depression group has low recuperative power. And these can be judged by Factor AA's height change.

Purpose: The most recent diagnostic criteria for periprosthetic joint infection (PJI) include the use of the alpha-defensin (AD) lateral-flow (LF) test, but hip and knee arthroplasties were usually combined in previous studies. This prospective study was designed to examine the accuracy of the AD-LF test for diagnosis of PJI in chronic painful total hip arthroplasties (THA). Materials and Methods: Patients with chronic painful hip arthroplasties were prospectively enrolled between March 2018 and May 2020. Exclusion criteria included acute PJI or an insufficient amount of synovial fluid. The modified Musculoskeletal Infection Society (MSIS) criteria were primarily used for PJI diagnosis. Fifty-seven patients were included in the analysis group. Revision surgery was not performed in 38 patients, for different reasons (clinical group); these patients remain "Schrödinger's hips": in such cases PJI cannot be excluded nor confirmed until you "open the box". Results: The result of the AD-LF test was positive in nine patients and negative in 48 patients. Six patients were diagnosed with PJI. AD-LF sensitivity (MSIS criteria) was 83% (95% confidence interval [CI] 36-100%) and specificity was 92% (95% CI 81-98%). The positive and negative predictive value were 56% and 98%, respectively. Conclusion: The AD test is useful in addition to the existing arsenal of diagnostic tools, and can be helpful in the decision-making process. Not all patients with chronical painful THA will undergo revision surgery. Consequently, in order to determine the reliable diagnostic accuracy of this test, future PJI diagnostic studies should include a second arm of "Schrödinger's hips".
