Tattooing is an invasive procedure that involves the introduction of permanent pigments into the dermis, and is categorized as a medical procedure in Korea. Despite the medical, cosmetic, and aesthetic purposes of tattooing, legislative proposals to allow non-medical personnel to perform tattooing have consistently been rejected on public health grounds, prioritizing health and safety considerations. Professional organizations have maintained a consistent position, highlighting the risks of allowing non-medical individuals to perform tattooing. These risks include procedural complications, use of unsafe practices, and inadequate legal frameworks to ensure accountability.Addressing such issues requires careful consideration beyond economic or convenience factors, with an emphasis on public health policies. To address these concerns, the Korean Dermatological Research Foundation convened its 1st Policy Forum on October 6, 2024. The forum discussed the safety aspects, medical complications, and legal implications of tattooing performed by non-medical personnel. These findings highlight the significant risks and regulatory gaps associated with such practices, underscoring the need for a comprehensive review and stringent regulations to protect public health.

Objective: This study was conducted to examine the trends in patient visits to the emergency departments (EDs) during the coronavirus disease 2019 (COVID-19) pandemic and analyze the changes in the pattern of ED utilization over time. Methods: We analyzed the National Emergency Department Information System data on ED visits for 3 years, from January 1, 2018 to December 31, 2020. Results: A total of 25,260,790 patients visited the ED during the study period. There was a notable 23.3% decrease in visits in 2020 during the pandemic compared to the preceding year. The number of patients visiting the ED appeared to decrease in response to the increase in confirmed COVID-19 cases. In 2020, a total of 13,801 patients were diagnosed with COVID-19 in the ED, accounting for 22.7% of the confirmed COVID-19 cases in the country. In 2018, 2019, and 2020, ED visitors presenting with respiratory symptoms as their chief complaint numbered 1,438,137 (15.5%), 1,605,551 (17.7%), and 1,019,314 (14.7%), respectively. The length of stay of these patients increased at the regional and local emergency centers. However, a reverse trend was observed at local emergency medical agencies. Conclusion During the COVID-19 pandemic in 2020, patient visits to the ED decreased, irrespective of patient’s health status. The concentration of emergency and isolation-requiring patients at regional emergency medical centers and local emergency medical centers led to an increase in the length of stay. Further analysis and research are needed to assess the role of the local emergency medical agencies in the response to infectious diseases in the future.

Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents.. The Korea Colon Cancer Multidisciplinary (KCCM) Committee intends to provide professionals who treat colon cancer with the most up-to-date, evidence-based practice guidelines to improve outcomes and help them make decisions that reflect their patients’ values and preferences. These guidelines have been established by consensus reached by the KCCM Guideline Committee based on a systematic literature review and evidence synthesis and by considering the national health insurance system in real clinical practice settings. Each recommendation is presented with a recommendation strength and level of evidence based on the consensus of the committee.

This report presents the latest statistics on the stroke population in South Korea, sourced from the Clinical Research Collaborations for Stroke in Korea-National Institute for Health (CRCS-K-NIH), a comprehensive, nationwide, multicenter stroke registry. The Korean cohort, unlike western populations, shows a male-to-female ratio of 1.5, attributed to lower risk factors in Korean women. The average ages for men and women are 67 and 73 years, respectively.Hypertension is the most common risk factor (67%), consistent with global trends, but there is a higher prevalence of diabetes (35%) and smoking (21%). The prevalence of atrial fibrillation (19%) is lower than in western populations, suggesting effective prevention strategies in the general population. A high incidence of large artery atherosclerosis (38%) is observed, likely due to prevalent intracranial arterial disease in East Asians and advanced imaging techniques.There has been a decrease in intravenous thrombolysis rates, from 12% in 2017–2019 to 10% in 2021, with no improvements in door-to-needle and door-to-puncture times, worsened by the coronavirus disease 2019 pandemic. While the use of aspirin plus clopidogrel for noncardioembolic stroke and direct oral anticoagulants for atrial fibrillation is well-established, the application of direct oral anticoagulants for non-atrial fibrillation cardioembolic strokes in the acute phase requires further research. The incidence of early neurological deterioration (13%) and the cumulative incidence of recurrent stroke at 3 months (3%) align with global figures. Favorable outcomes at 3 months (63%) are comparable internationally, yet the lack of improvement in dependency at 3 months highlights the need for advancements in acute stroke care.

Whether advanced age is associated with poor outcomes of elderly patients with acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT) is controversial. This study aimed to evaluate age effect and predictors for mortality in elderly AKI patients undergoing CRRT. Methods: Data of 480 elderly AKI patients who underwent CRRT were retrospectively analyzed. Subjects were stratified into two groups according to age: younger-old (age, 65–74 years; n = 205) and older-old (age, ≥75 years; n = 275). Predictors for 28-day and 90-day mortality and age effects were analyzed using multivariable Cox regression analysis and propensity score matching. Results: Urine output at the start of CRRT (adjusted hazard ratio [aHR], 0.99; 95% confidence interval [CI], 0.99–1.00; p = 0.04), operation (aHR, 0.53; 95% CI, 0.30–0.93; p = 0.03), and use of an intra-aortic balloon pump (aHR, 3.60; 95% CI, 1.18–10.96; p = 0.02) were predictors for 28-day mortality. Ischemic heart disease (aHR, 1.74; 95% CI, 1.02–2.98; p = 0.04) and use of a ventilator (aHR, 0.56; 95% CI, 0.36–0.89; p = 0.01) were predictors for 90-day mortality. The older-old group did not exhibit a higher risk for 28- day or 90-day mortality than the younger-old group in multivariable or propensity score-matched models. Conclusion: Advanced age was not a risk factor for mortality among elderly AKI patients undergoing CRRT, suggesting that advanced age should not be considered for therapeutic decisions in critically ill elderly patients with AKI requiring CRRT.
