Background: Serum calcium and magnesium levels are a key factor of the coagulation cascade and may potentially contribute to the pathophysiology of intracerebral hemorrhage (ICH) expansion. The aim of this study was to attain and sustain target levels of serum calcium and magnesium for three days following admission. Methods: A single-blind, prospective, multicenter randomized study was conducted from 2019 to 2022 years, enrolling acute ICH patients aged 18–80 years, with radiological diagnosis and without surgical intervention. Participants were randomly assigned in a 1:1 ratio to either the study group or the control group. In the study group, the target serum levels of calcium (9–10.2 mg/dL) and magnesium (2–3 mg/dL) were actively achieved and maintained for a duration of 3 days following admission. The primary outcome was the expansion of ICH volume within the first 3 days between the study group and the control groups. Results: After implementing inclusion/exclusion criteria, 105 of 354 patients remained in the study. There were no significant differences in ICH volume on hospital days 2 and 3 between the groups. Admission factors including Glasgow coma scale score, hemoglobin level, ICH volume, and spot sign showed significant correlations in multivariate analysis. On the third day of hospitalization, admission serum magnesium levels showed a significant correlation with ICH expansion, whereas calcium levels did not. Conclusion Admission serum magnesium levels were found to correlate with hematoma expansion in patients with acute ICH. While magnesium itself may not be a direct therapeutic target, it could serve as a valuable indicator for identifying potential therapeutic strategies aimed at preventing ICH volume increase.

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.
