Background: With the increase in meals at home due to coronavirus disease 2019 (COVID-19), the pattern and incidence of enteritis seemed to change. Some types of enteritis, such as Campylobacter enteritis, appear to have increased. Our study aimed to evaluate the change in the trend of enteritis, especially Campylobacter enteritis, before COVID-19 (2016– 2019) and at the present time during COVID-19 in South Korea. Methods: We analyzed data from the Health Insurance Review and Assessment Service. From 2016 to 2020, the International Classification of Diseases codes related to enteritis were examined to distinguish bacterial and viral enteritis and the trends of each were analyzed. The aspects of enteritis, before and after the COVID-19 outbreak, were compared. Results: Both bacterial and viral enteritis declined in all age groups from 2016 to 2020 (P < 0.001). In 2020, the reduction rate of viral enteritis was higher than that of bacterial enteritis. However, unlike other causes of enteritis, even after COVID-19, Campylobacter enteritis increased in all age groups. An increase of Campylobacter enteritis in 2020 was particularly noticeable in children and adolescents. The prevalence of viral and bacterial enteritis was higher in urban areas than in rural areas (P < 0.001). Campylobacter enteritis was more common in the rural areas (P < 0.001). Conclusion: Although the prevalence of bacterial and viral enteritis have decreased in COVID-19, Campylobacter enteritis has increased in all age groups and in rural areas compared to urban areas. Recognizing that the trend of Campylobacter enteritis before and during COVID-19 is helpful for future public health measures and interventions.

Objectives: The aim of this study was to examine the effect of TMJ Balancing Appliance (TBA) on healthy humans by using power spectral analysis of Electroencephalogram (EEG). Methods: 50 healthy volunteers participated in this study. A thirty-two channel EEG device was used for this study on 50 subjects (28 males, 22 females; mean age=25.3 years old). Results: 19 channel was measured and analysed. The relative power values in α, β, γ, Senorimotor rhythm (SMR), mid-β, high-β band and concentration index ((SMR wave+Mid-β wave)/θ) increased insignificantly. Relaxation index(α/High-β wave) increased significantly (p<0.05) comparing to the before the TBA application. After the TBA application, the relative power values in α, β, γ, SMR (Senorimotor rhythm), mid-β, high-β band and concentration index((SMR wave+Mid-β wave)/θ) increased insignificantly. Relaxation index (α/High-β wave) increased significantly (p <0.01) comparing to the before the TBA application. Conclusions: These results suggest that TBA application causes significant changes on relaxation index. Application of TBA shall regulate the function of the cerebral cortex increase parasympathetic nervous activity.
