ABSTRACT
Background@#The purpose of this study is to investigate the pro-con of re-implementation by administrative areas and the difference in perception of community water fluoridation in implemented and non-implemented areas after the community water fluoridation in Korea was suspended. Through this, we intend to provide basic data that can help find ways to increase the support and interest of local residents. @*Methods@#The 601 questionnaires collected through the survey and statistical analysis was conducted using SPSS Statistics 28.0. @*Results@#As a result of analyzing the perception of the community water fluoridation according to the understanding of fluorine, the proportion of people who were not recognized by both fluorine and community water fluoridation was the highest (p＜0.05). As a result of the analysis of the pro-con of re-implementation of community water fluoridation, the approval was high. Among those who responded in favor, the place of re-implementation showed that ‘implementation nationwide’ was high. As for the reason for favor, it was found that it was possible to prevent dental caries disease. The reason for the objection was the lack of knowledge about fluoride. @*Conclusion@#The results of the survey for the pro-con of the re-implementation of community water fluoridation showed a higher degree of ‘agree’ and showed that people in the area where community water fluoridation was not implemented showed higher interest in oral health prevention and management. Through this, not only oral education, but also correct information on the implementation method of community water fluoridation, the benefits of community water fluoridation, and the facts that were misunderstood in the past, as well as oral education, can be provided to raise interest in community water fluoridation. It is thought that the expected effect of the re-implementation of community water fluoridation can be obtained if such activities are carried out.
ABSTRACT
Background@#To compare the muscle strength of patients with a hip fracture according to the presence of sarcopenia after surgery and the correlation of measured values between a Biodex and surface electromyography (sEMG) in postoperative measurement of muscle strength. @*Methods@#Seventy-one patients who underwent hip fracture surgery were included in this study. Muscle mass was measured using dual energy X-ray absorptiometry and the grip strength was evaluated using a dynamometer. The diagnosis of sarcopenia followed the Asian Working Group for Sarcopenia criteria. We evaluated the Biodex to assess muscle strength according to the presence of sarcopenia and at the same time measured the sEMG to evaluate the correlation of muscle strength between Biodex and sEMG. @*Results@#We assigned 34 patients with sarcopenia and 37 without sarcopenia to 2 groups. In the comparison of muscle strength using Biodex and sEMG between the 2 groups, it was confirmed that muscle strength of sarcopenia group was decreased compared with that of the non-sarcopenia group, although there was no statistical significance between the groups. However, Biodex and sEMG showed very close correlation with muscle strength in all variables. @*Conclusions@#We suggest that using sEMG for the evaluation of muscle strength after hip fracture surgery may be an excellent tool alternative to isokinetic testing machines such as the Biodex.
ABSTRACT
OBJECTIVE: Placental site trophoblastic tumor (PSTT) is the rarest form of gestational trophoblastic disease (GTD) and the optimum management is still controversial. In this study, we analyzed the clinical features, treatment, and outcomes of 6 consecutive patients with PSTT treated in our institution. METHODS: The electronic medical record database of Samsung Medical Center was screened to identify patients with PSTT from 1994 to 2017. Medical records for the details of each patient's clinical features and treatment were extracted and reviewed. This study was approved Institutional Review Board of our hospital. RESULTS: A total of 418 cases of GTD, 6 (1.4%) patients with PSTT were identified. The median age of the patients was 31 years. The antecedent pregnancy was term in all 5 cases with available antecedent pregnancy information and the median interval from pregnancy to diagnosis of PSTT was 8 months. The median titer of serum beta human chorionic gonadotropin (β-hCG) at diagnosis was 190.9 mIU/mL. Five (83.3%) patients presented with irregular vaginal bleeding and one (16.7%) had amenorrhea. All patients had disease confined to the uterus without metastasis at diagnosis and were successfully treated by hysterectomy alone. All of them were alive without disease during the follow-up period. CONCLUSION: In this study, we observed low level serum β-hCG titer and irregular vaginal bleeding with varying interval after antecedent term pregnancy were most common presenting features of PSTT. In addition, we demonstrated hysterectomy alone was successful for the treatment of stage I disease of PSTT.
