Dangerous exposures to chemicals managed by Poison Centers all around the world during the COVID-19 pandemic: a systematic review and proportional meta-analysis.

INTRODUCTION: During COVID-19 pandemic, cleaning/disinfection activities were highly recommended. This study summarizes the state of art and estimates the prevalence of dangerous exposures to specific chemicals managed by Poison Centers (PCs) from all over the world during 2020 vs 2019, trying to overcome the critical aspects of the product categorization systems used by PCs. MATERIALS AND METHODS: A systematic research was conducted in 3 major databases and 2 websites of PCs associations. Proportional meta-analyses were performed to estimate the prevalence of exposures to disinfectants, household products and hand sanitizers in 2020 vs 2019. RESULTS: The pooled prevalence of exposures to disinfectants, household products and hand sanitizers were respectively 5.9% (95% CI 4.9-7.0) (2019: 4.4% vs 2020: 7.8%; p=0.22), 25.9% (95% CI 24.0-27.7) (2019: 25.0% vs 2020: 28.6%; p=0.71) and 1.6% (95% CI 1.3-1.9) (2019: 0.6% vs 2020: 2.8%; p<0.001). CONCLUSIONS: This study detected overall increases of exposures to specific chemicals in 2020, suggesting that the awareness on topics related to the safe use of these products should be improved, especially during health emergencies, highlighting the need to develop standardized systems to better compare data coming from PCs all over the world.

Lessons learned in a decade: Medical-toxicological view of tattooing.

Tattooing has been part of the human culture for thousands of years, yet only in the past decades has it entered the mainstream of the society. With the rise in popularity, tattoos also gained attention among researchers, with the aim to better understand the health risks posed by their application. 'A medical-toxicological view of tattooing'-a work published in The Lancet almost a decade ago, resulted from the international collaboration of various experts in the field. Since then, much understanding has been achieved regarding adverse effects, treatment of complications, as well as their regulation for improving public health. Yet major knowledge gaps remain. This review article results from the Second International Conference on Tattoo Safety hosted by the German Federal Institute for Risk Assessment (BfR) and provides a glimpse from the medical-toxicological perspective, regulatory strategies and advances in the analysis of tattoo inks.
