Demographic and Tumor Characteristics of Patients Younger Than 50 Years With Nonmelanoma Skin Cancer Referred for Mohs Micrographic Surgery
BACKGROUND:An increase in nonmelanoma skin cancer (NMSC) in younger patients has been reported. Many are treated with Mohs micrographic surgery (MMS). OBJECTIVE:Investigate patient and tumor characteristics in patients less than 50 years undergoing MMS for NMSC at a large, referral-based practice. METHODS & MATERIALS/METHODS:Retrospective chart review of 1,332 tumors occurring in 1,018 consecutive patients over a five-year period. RESULTS:81.7% of tumors were BCC and 55.3% occurred in women. Patients less than 30 years were more likely to be female (P equals 0.016) and women were more likely to have BCC (P equals 0.010). SCCs were more likely with increasing age (P less than 0.001). Of all tumors, 3.6% were recurrent, 2.7% had diameters â‰¥ 2 centimeters, and 5.5% of all BCCs had a high-risk histologic subtype. Women were more than twice as likely as men to be referred to plastic surgery for repair (P equals 0.020). CONCLUSION/CONCLUSIONS:Patients < 50 years with NMSC may represent a growing population referred for MMS, especially young women with BCC. High-risk tumor features were rare among young patients, and female gender was associated with an increased rate of referral for repair by a plastics subspecialty. Study was performed at the Laser & Skin Surgery Center of New York.

SAFETY OF PERFLUORODECALIN-INFUSED SILICONE PATCH IN PICOSECOND LASER-ASSISTED TATTOO REMOVAL [Meeting Abstract]
Pulsed Dye Laser at Subpurpuric Settings for the Treatment of Pulsed Dye Laser-Induced Ecchymoses in Patients With Port-Wine Stains
BACKGROUND: Post-procedure purpura is a major complaint of patients with port-wine stains (PWSs) treated with pulsed dye laser (PDL). OBJECTIVE: To assess the safety and efficacy of using PDL at nonpurpuric settings to treat ecchymoses that develop within PWSs after treatment with PDL. MATERIALS AND METHODS: Prospective, randomized, controlled study using 595-nm PDL for treatment of PWSs and laser-induced ecchymoses. Port-wine stains were treated in entirety at baseline. Two days later, ecchymoses on randomly selected half of the lesion were re-treated with PDL at subpurpuric settings. Treatment series was repeated 4 to 8 weeks later, and follow-up was at 1 month. Reduction in bruising and PWS clearance were assessed. Three masked evaluators graded clinical improvement using a 4-point scale (1 = 1%-25% improvement, 2 = 26%-50% improvement, 3 = 51%-75% improvement, and 4 = 76%-100% improvement). RESULTS: Twenty adults with 21 PWSs on the head, trunk, and extremities were treated. After first treatment, reduction of bruising was graded a mean value of 2.43 for the treatment side, compared with 1.93 for the control side (p = .012); after the second treatment, 2.83 compared with 2.40 (p = .021). No significant adverse events occurred. CONCLUSION: Pulsed dye laser can be used safely and effectively to reduce treatment-induced purpura in patients with PWSs.
Successful and safe use of Q-switched lasers in the treatment of nevus of Ota in children with phototypes IV-VI
OBJECTIVE: Nevus of Ota represents congenital dermal melanocytosis in a trigeminal distribution, most commonly occurring in Asian individuals and other individuals with skin of color. Evidence suggests early treatment is beneficial. Multiple reports have shown efficacy and safety of Q-switched laser treatment in adults. There is little data on children and in non-Asian skin types. This series was done to demonstrate safe and effective use of Q-switched laser therapy in children of multiple skin types. STUDY DESIGN: Retrospective case series. METHODS: This was a chart review of patients under 18 years old who presented to our practice from 2002 to 2015 with a clinical diagnosis of nevus of Ota who were treated with Q-switched lasers (694 and 1,064 nm). Patients were treated without the use of general anesthesia or sedation, and corneal shields were used in appropriate cases. Percentage of improvement as well as side effects were rated by five physicians independently. Improvement, when present, was rated in quartiles (1-25%, 26-50%, 51-75%, and 76-100% improvement). RESULTS: Twenty-four children were included. The average age at the start of treatment was 3.9 years old (range of 3 months to 12.4 years), and patients had Fitzpatrick skin types IV through VI. The mean number of treatments was 9.3. Assessment revealed excellent response (76-100% improvement) in 70% of patients and good to excellent response (51-100% improvement) in 86%. Two patients (8%) had post-inflammatory hyperpigmentation, one of whom also had focal hypopigmentation. CONCLUSION: Treatment of nevus of Ota with Q-switched lasers in children with skin of color, without general anesthesia or sedation, is safe and effective. Early intervention should be encouraged for better efficacy and to prevent psychosocial distress in later childhood and adulthood. Lasers Surg. Med. (c) 2017 Wiley Periodicals, Inc.
Lasers, Light, and the Treatment of Acne: A Comprehensive Review of the Literature
INTRODUCTION/BACKGROUND:Acne vulgaris is common dermatologic condition with an estimated prevalence of 70 to 87%. Acne has been shown to have a significant impact on patient quality of life and mental health, especially as inflammatory lesions typically occur on cosmetically sensitive areas with the potential for permanent scarring. There have been numerous advances in the treatment of inflammatory acne with light-based and laser devices. OBJECTIVE:To review the current evidence for light-based and laser treatments in the management of inflammatory acne. METHODS:An analysis was conducted of PubMed indexed English language literature regarding management of inflammatory acne using light-based and laser treatments. RESULTS:Evidence for the utilization of laser and light-based therapy for acne was summarized in a comprehensive review. Laser and light-based treatment holds the advantages of improved patient compliance and safety profiles in comparison to pharmacologic therapy. Efficacy of device based treatment varied in comparison to standard topical treatment regimens, often more effective when used in combination therapy. Adverse effects reported were generally self-limited. DISCUSSION/CONCLUSIONS:These treatments do and will continue to play an important and enlarging role in the management of acne. Larger scale studies with standardization of treatment protocols are warranted. <p><em>J Drugs Dermatol. 2017;16(11):1095-1102.</em></p>.
Isotretinoin and Timing of Procedural Interventions: A Systematic Review With Consensus Recommendations
Importance: The notion that systemic isotretinoin taken within 6 to 12 months of cutaneous surgery contributes to abnormal scarring or delayed wound healing is widely taught and practiced; however, it is based on 3 small case series from the mid-1980s. Objective: To evaluate the body of literature to provide evidence-based recommendations regarding the safety of procedural interventions performed either concurrently with, or immediately following the cessation of systemic isotretinoin therapy. Evidence Review: A panel of national experts in pediatric dermatology, procedural/cosmetic dermatology, plastic surgery, scars, wound healing, acne, and isotretinoin was convened. A systematic PubMed review of English-language articles published from 1982 to 2017 was performed using the following search terms: isotretinoin, 13-cis-retinoic acid, Accutane, retinoids, acitretin, surgery, surgical, laser, ablative laser, nonablative laser, laser hair removal, chemical peel, dermabrasion, wound healing, safety, scarring, hypertrophic scar, and keloid. Evidence was graded, and expert consensus was obtained. Findings: Thirty-two relevant publications reported 1485 procedures. There was insufficient evidence to support delaying manual dermabrasion, superficial chemical peels, cutaneous surgery, laser hair removal, and fractional ablative and nonablative laser procedures for patients currently receiving or having recently completed isotretinoin therapy. Based on the available literature, mechanical dermabrasion and fully ablative laser are not recommended in the setting of systemic isotretinoin treatment. Conclusions and Relevance: Physicians and patients may have an evidence-based discussion regarding the known risk of cutaneous surgical procedures in the setting of systemic isotretinoin therapy. For some patients and some conditions, an informed decision may lead to earlier and potentially more effective interventions.
A Prospective Study of Axillary Hair Reduction in Patients Treated With Microwave Technology
BACKGROUND: Removing unwanted body hair is a growing trend in society today, and there are many laser-based devices for hair reduction. There are some limitations to those methods, including the lack of efficacy for lighter color hair. OBJECTIVE: The objective was to quantify hair reduction in the axillae after treatment with a noninvasive microwave energy device. MATERIALS AND METHODS: A prospective, multicenter study was performed at 3 private dermatology clinics. Fifty-six adult subjects seeking axillary hair reduction were enrolled and treated with the device in 1 or 2 treatment sessions 3 months apart at various energy levels, and followed for 12 months. The primary analysis was monitoring reduction of hair counts from baseline to follow-up visits. A subject assessment of overall satisfaction, odor ratings, and sweat reduction ratings was provided at follow-up visits. RESULTS: Fifty-six subjects received treatment, with an average total underarm hair reduction of approximately 70% for both light and dark hair. Percentage of patients with hair reduction of 30% or more was significantly higher than 50% at all follow-up visits. Half of treated subjects reported expected mild transient post-treatment effects such as localized edema, discomfort, and bruising. Other reported events were mild. CONCLUSION: This clinical study provides evidence for safe and permanent axillary hair reduction, showing stable average reduction that lasted through the year of follow-up. Most notably, the study has shown the treatment's efficacy for reduction of light-colored axillary hair.
