Article Synopsis
  • The study discusses a case of a 21-year-old woman with rare, grouped lesions known as acquired agminated nevi located in her axillae.
  • Using a picosecond 532 nm Nd:YAG laser, significant cosmetic improvement was achieved after multiple treatments, outperforming other laser types.
  • The research highlights the uniqueness of the case due to the bilateral occurrence of the nevi and emphasizes the importance of monitoring post-treatment since potential risks like atypia and melanoma can arise.

Objectives: To characterize the properties of cutaneous defects created by energy-based devices using optical coherence tomography.

Materials And Methods: Radiofrequency (RF) microneedling and non-ablative fractional laser (NAFL) treatment were performed in vivo with various parameters. Following treatment, optical coherence tomography (OCT) was used to image and measure cutaneous defects at multiple time points over a 24 h period.

Objectives: The absorption of biostimulatory particulate matter following its application to fractional skin defects remains poorly understood, and even less is known about its in vivo impact in terms of tissue integration. The objectives of this study are twofold: (1) to evaluate the potential of calcium hydroxylapatite (CaHA) to penetrate through skin treated with a fractional laser; and (2) to assess the effectiveness of clinical laser scanning microscopy technologies in monitoring the effects of such treatment over time.

Methods: One area on a volunteer's arm was treated with a fractional erbium laser (Sciton Inc.

Article Synopsis
  • Iatrogenic cutaneous siderosis is a skin condition characterized by dark patches near injection sites from iron infusions, causing aesthetic and psychological issues for patients, and often doesn't resolve on its own.
  • A systematic review of the effectiveness of energy-based devices to treat this condition included 54 female patients, mostly around 44 years old, primarily affected after intravenous iron infusion for iron deficiency anemia.
  • Six different laser systems were analyzed, showing over half of patients experienced complete clearance after an average of 5.4 treatments, with the Nd:YAG 532 nm laser showing the best results in the case discussed.

Article Synopsis
  • The popularity of cosmetic and corrective tattoos is rising, leading to a higher demand for effective removal methods.
  • Traditional removal techniques like surgical excision and dermabrasion are being replaced by lasers, which are now seen as reliable for tattoo removal.
  • This CME aims to educate on the various laser tattoo removal methods, including selection, application, safety, and factors influencing the choice of laser for best results.
