The 585-nm PDL is effective and safe in improving the quality and cosmetic appearance of surgical scars in skin types I-IV starting on the day of suture removal.

The rapidity of biofilm growth suggests that bacteria in wounds possess the capacity of producing this shield against antibiotics and immune effector cells early in the infection process. Therefore, efforts to prevent or slow the proliferation of bacteria and biofilms should occur soon after a wound is created. Additionally, this staining technique can be used to demonstrate the ability of agents to slow biofilm growth or to interrupt formed biofilm and may be useful in future studies of chronically infected wounds.

Dermal melanocytosis is most commonly found in the skin of Asians and other darkly pigmented people. It is histologically characterized by the presence of dermal melanocytes, with or without presence of dermal melanophages. Mongolian spot, nevus of Ito, nevus of Ota, nevus of Hori, and blue nevus are most common and represent distinct types of dermal melanocytosis. Other clinical patterns of acquired dermal melanocytosis have also been described. Herein, we report a unique case of acquired dermal melanocytosis diffusely affecting the entire back of a 50-year old African-American male and also review and discuss various patterns of unusual acquired dermal melanocytosis.
