BACKGROUND/AIMS: Despite the clinical importance anaphylaxis and the recent increase in its occurrence, studies regarding the epidemiology of anaphylaxis, risk factors for anaphylaxis, and epinephrine auto-injector (EAI) prescription status for patients with anaphylaxis remain poorly described. Thus, we investigated the prevalence of anaphylaxis and prescription rates of EAI in urban and rural areas in Korea. METHODS: We used data from the 2010 to 2014 Health Insurance Review and Assessment database. Anaphylaxis was identified through physician-certified diagnoses using the International Classification of Diseases 10th (ICD-10) codes (T780, T782, T805, T886). Data on prescription rates of EAI were collected from the Korea Orphan & Essential Drug Center, the only pharmacy exclusively dealing with EAI in Korea. The prescription rates of EAI were defined as the number of EAI prescribed against the number of patients with anaphylaxis. RESULTS: The prevalence of anaphylaxis over the 5-year period was 0.023%. The annual prevalence of anaphylaxis increased over the 5-year period. Anaphylaxis was more common in males than in females (54% vs. 46%) and in the population aged 50 to 59 years old. For regional analysis, urban areas showed a relatively lower prevalence of anaphylaxis (17.3 per 100,000 individuals) along with higher prescription rates (12.0%) of EAI for patients with anaphylaxis. In contrast, rural areas showed a relatively higher prevalence of anaphylaxis (28.8 per 100,000 individuals) along with lower prescription rates (3.1%) of EAI. CONCLUSIONS The prevalence of anaphylaxis has increased annually in Korea. There were regional differences in the prevalence of anaphylaxis and prescription rates of EAI between urban and rural areas in Korea.

Purpose: This study explored the factors influencing the health-related life satisfaction of people with disabilities who engaged in physical activity, by age and gender. Methods: A secondary analysis was conducted of the 2020 Third Disability and Life Dynamics Panel (2021). The participants were 2,796 people who performed regular physical activity at least once a week. The variables selected were disability-related factors (degree of disability, multiple disabilities, and type of disability), sociodemographic factors (age, gender, living alone, and mean monthly family income), and health-related factors (amount of physical activity, self-esteem, depression, chronic disease, subjective health, and health-related life satisfaction). Descriptive statistics, the chi-square test, the t-test, two-way analysis of variance, and multiple regression analysis were conducted. Results: In total, 58.0% of participants were male, and 42.0% were female. For age groups, 14.4% were children/adolescents (0–19 years), 42.6% were adults (20–59 years), and 43.0% were seniors (≥60 years). The mean score for health-related life satisfaction was 5.0±2.15 out of 10. Adults and seniors whose level of physical activity met or exceeded recommendations had higher subjective health. Moreover, men had better subjective health than women in seniors. Health-related life satisfaction was higher among those who had higher self-esteem, were not depressed, did not have chronic diseases, and had better subjective health. Conclusion Gender significantly influenced health-related life satisfaction in children/ adolescents and seniors. Disability-related factors were significant in adults, and health-related factors were significant in all age groups. Therefore, these factors should be considered when designing interventions to promote subjective health and health-related life satisfaction of people with disabilities.

Tetanus immunoglobulin (TIG) and tetanus vaccination are in general use for tetanus prophylaxis in patients with trauma based on their personal history of tetanus vaccinations. However, the conventional injection of only TIG has been used for tetanus prophylaxis due to difficulties in verifying the known vaccination histories of Korean patients. We evaluated the effect of introducing an immunization information system (IIS) on tetanus prophylaxis. TIG-injected trauma patients (≥20 years old) who were registered at a single hospital from January 1, 2013 to December 31, 2015 were enrolled in this study. IIS was introduced to all doctors in that hospital starting on January 1, 2015. IIS information and medical records were used to assess histories of tetanus vaccination and TIG administration. Comparisons were made between the number of tetanus and TIG shots (inadequate TIG administrations) given before and after the introduction of the IIS. The number of TIG-injected patients varied during the study period (362 in 2013, 387 in 2014, and 235 in 2015). The proportion of tetanus-vaccinated patients relative to TIG-injected patients increased from 2.21% in 2013 to 4.13% in 2014 and 44.26% in 2015 (P <0.001). The proportions of cases that were recorded as having received inadequate TIG administration decreased from 3.59% (13 of 362) in 2013 for patients with ≥3 tetanus vaccinations to 4.39% (17 of 387) in 2014 and 1.28% (3 of 235) in 2015 for the same group P = 0.043). The introduction of IIS could increase the number of patients with trauma who have proper tetanus vaccinations and decrease the number who undergo inadequate TIG administrations. The introduction of IIS can improve clinical practice in terms of enhancing proper tetanus prophylaxis for appropriate patients.

Background and Objectives: Burning mouth syndrome (BMS) is a chronic pain disorder involving a burning sensation of the oral cavity without any identifiable oral lesion. According to the recent studies, the pathogenesis of BMS is presumed to be caused by a neuropathic condition. Gabapentin and pregabalin have been used for various neuropathic pains, but pregabalin has several pharmacokinetic advantages over gabapentin. To our best knowledge, there are no recent studies reported on the administration of pregabalin in treating BMS in Korea. Therefore, in this study, we investigated the therapeutic effect of pregabalin in treating BMS.Subjects and Method We chose as candidates 33 patients diagnosed as BMS and took pregabalin for more than four weeks. Pregabalin was administered at 75 mg once a day for 2 to 4 weeks at first, and then the dose was modified depending on whether or not symptoms improved. Effectiveness of treatment was evaluated in the way that the patients subjectively answered whether or not symptoms were improved. Results: A total of 21 (63.6%) out of 33 patients were responsive to the treatment. Among those, at the last follow-up, 8 patients (38.1%) showed slight improvement, and 13 patients (61.9%) showed mostly improvement or disappearance of symptoms. The average time interval from starting pregabalin to the first symptom improvement was 50.1 days, and most patients showed symptom improvement within 8 weeks. Conclusion This study concludes that pregabalin can be added as a meaningful option in the treatment of BMS. The additional double-blind clinical study should be followed to further prove the effectiveness of pregabalin.

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.

Purpose: Endoscopic submucosal dissection (ESD) is the standard treatment for early gastric cancer (EGC) with a low risk of lymph node metastasis. In Korea, ESD was included in the National Health Insurance (NHI) coverage in 2011, which was expanded in 2018. In the present study, we investigated the status and trends of ESD for EGC over the past decade since its incorporation into the NHI system. Materials and Methods: We analyzed the data from the National Health Insurance Service (NHIS) database from 2011 to 2021, focusing on patient characteristics, number of ESD procedures, in-hospital length of stay (LOS), and total medical cost (TMC) per admission. In addition, we conducted an interrupted time series analysis to assess the impact of changes in insurance coverage on these variables. Results: Overall, 95,348 cases of ESD for EGC were identified. A consistent annual increase in ESD procedures was observed, particularly in tertiary care hospitals and among patients aged >60 years. The overall median LOS and TMC were 4 days and 2,123,000 KRW, respectively. The 2018 insurance coverage expansion did not significantly affect the number of ESD procedures or LOS; however, the TMC increased significantly. Conclusions Our study illustrates decade-long trends in the ESD for EGC in Korea. The policy needs to be revised continuously to optimize ESD use and improve resource allocation within healthcare systems.
