background. The CO 2 laser for cutaneous resurfacing has been associated with the reactivation of herpes simplex virus (HSV), causing delayed reepithelialization and scarring. Antiviral agents appear to be effective in reducing reactivation, however, the optimal therapeutic regimen has yet to be clearly defined. objective. To assess the reactivation rates of HSV after CO 2 laser resurfacing in patients who received prophylactic valacyclovir for either 10 or 14 days. methods.

Facial rejuvenation is rapidly evolving sector in the field of facial aesthetics. There is a wide variety of dermal fillers and many more are in development. Over the past few years, the study of adult-derived stem cells has become a very active area of research. Adult stem cells are an attractive option for volume restoration and facial rejuvenation. Adult stem cells are isolated from adipose tissue-adipose derived stem cells and have mesodermal, ectodermal, and endodermal potentials. Adipose-derived stem cells could conceivably be an alternative to pluripotent embryonic stem cells and could play a critical role in the rapidly expanding fields of tissue engineering and regenerative medicine. This article reviews the history of soft tissue augmentation using adipose tissue grafting and the advent of using adipose-derived stem cells. The state-of-the-art stem cell isolation technique as well as anticipated future therapeutic indications are also addressed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
