ReviewPrevention and management of iatrogenic blindness associated with aesthetical filler injections.
Injectable fillers have become one of the most performed aesthetical treatments worldwide over the past two decades. They are frequently applied to the face, offering effective and safe alternatives to more invasive surgical procedures. ⋯ Visual impairment stands as a rare yet catastrophic adverse event associated with intravascular embolization of injected material to the retina or other areas of the central nervous system; potentially leading to permanent visual loss. This article presents a comprehensive revision of blindness secondary to aesthetical filler injections, offering up-to-date strategies for prevention and management.

LetterThe therapeutic effect of tanshinone IIA on Propionibacterium acnes-induced inflammation in vitro.
Acne vulgaris, a chronic inflammatory skin disease, affects many adolescents. New therapeutic agents for acne allow for a higher therapeutic activity, but fewer side effects. Tanshinone IIA, a natural product, has been proved to exhibit antibacterial and anti-inflammatory abilities in many diseases. ⋯ Enzyme-linked immunosorbent assay and quantitative real-time PCR were used to investigate the effect of tanshinone IIA on IL-1β, IL-8, and TNF-α expression, and western blot was used to examine TLR2, NF-κB, and intercellular cell adhesion molecule-1 (ICAM-1) protein level induced by P. acnes in THP-1 cells. Results showed that the expression of inflammatory cytokines and TLR2, NF-κB, ICAM-1 protein levels were inhibited by Tanshinone IIA, suggesting that tanshinone IIA appeared to suppress P. acnes-induced inflammation by blockade of TLR2/NF-κB signaling pathway. In conclusion, the present study revealed the inhibitory effect of tanshinone IIA on P. acnes-induced inflammation, providing an evidence to support the mechanism of anti-acne properties of tanshinone IIA.
