Port-wine stains are a type of capillary malformation affecting 0.3% to 0.5% of the population. Port-wine stains present at birth as pink to erythematous patches on the skin and/or mucosa. Without treatment, the patches typically darken with age and may eventually develop nodular thickening or associated pyogenic granuloma. Laser and light treatments provide improvement through selective destruction of vasculature. A variety of vascular-selective lasers may be employed, with the pulsed dye laser being the most common and well studied. Early treatment produces more optimal results. Advances in imaging and laser treatment technologies demonstrate potential to further improve clinical outcomes.

This is a very exciting time in cutaneous laser surgery with an ever-expanding therapeutic armamentarium and an increased sophistication of available technology. These recent trends have allowed for both a rapid development of interest and exploration of laser-assisted drug delivery and its potential applications. We review the current literature on anatomy, technology, and therapeutics as it relates to laser-assisted drug delivery. The focus of our review is on two areas of interest that have received much attention to date - photodynamic therapy in the treatment of actinic keratoses and nonmelanoma skin cancers as well as the treatment of scarring. We will also discuss potential complications of existing modalities used independently and in laser-assisted drug delivery and conclude with future indications for this burgeoning therapeutic methodology.

BACKGROUND: Multiple approaches to achieve eyelid tightening have been introduced over the years. However, a solid foundation of knowledge as to the origins of the aging appearance is paramount to target the specific causes of this natural phenomenon. OBJECTIVE: This review aims to touch upon the diverse modalities used to achieve the best therapeutic approach for eyelid tightening. MATERIALS AND METHODS: A review of published articles on eyelid tightening using blepharoplasty and lasers was conducted. This information combined with an illustrative case example is presented. RESULTS: Although multiple treatment options exist, there are advantages and disadvantages for each. CONCLUSION: Understanding the cause of the aging periorbital area with appropriate application of the various treatment options available will lead to a natural and youthful appearing result. Fractional ablative CO2 laser remains an excellent alternative to traditional blepharoplasty.

BACKGROUND: Long-term exposure to sunlight, including ultraviolet A and B, produces signs associated with photoaging and photodamage, including laxity and discoloration of the skin. Initial laser treatment for dyspigmentation included the use of ablative lasers, followed by Q-switched lasers and more recently fractional lasers
OBJECTIVE: We investigated the safety and efficacy of a fractionated 1927nm non-ablative thulium laser for the treatment of photo-induced pigmentation
METHODS: Prospective multi-center study of subjects with clinically identifiable photopigmentation. The study protocol was approved by BioMed Institutional Review Board (San Diego, CA). Subjects received two treatments with a non-ablative 1927nm fractionated thulium laser (Fraxel Dual 1550/1927 Laser System, Solta, Hayward CA), energy level of 10mJ, coverage of 40% and 4-6 passes. Subject pain, erythema and edema were recorded immediately after treatment. Two dimensional photography was obtained before each treatment and at one and three month follow up visits. Independent blinded physician assessment was performed evaluating overall improvement in appearance as well as pigment specific improvement
RESULTS: Forty men and women, ages 30 to 80 years, Fitzpatrick skin types I-IV, with photo-induced facial pigmentation were enrolled and treated, and 39 completed the three month follow up visit. Mean pain sensation for subjects during laser treatments was reported to be 4.3 on a 10-point scale. Mean scores for erythema, edema, and skin roughness throughout all treatments indicated moderate erythema, mild edema and mild skin roughness. Assessment of overall improvement was graded as moderate to very significant in 82% of subjects at one month and in 69% of subjects at three months after the second treatment. Assessment of lentigines and ephelides demonstrated moderate to very significant improvement in approximately 68% of subjects at the one month and in 51% of subjects at three months after the second treatment. Independent blinded physician assessment of randomized photography also demonstrated a durable response at three month follow up visit. Treatment was well tolerated and no serious adverse events related to treatment were observed or reported. Study limitations included a limited number of male subjects, lack of Fitzpatrick skin types V and VI, and decrease in improvement at 3 months post-treatment
CONCLUSIONS: Two treatments with a 1927nm non-ablative fractionated thulium laser produced moderate to marked improvement in overall appearance and pigmentation with high patient satisfaction. The response to treatment was maintained at one and three months follow up

BACKGROUND: Connective tissue diseases (CTD), including lupus erythematosus (LE), scleroderma, sarcoidosis, and dermatomyositis, present with clinically unique cutaneous manifestations often resistant to conventional therapy. The use of lasers in the treatment of various dermatologic conditions continues to expand, presenting an opportunity for incorporation of another mechanism of action in the treatment of CTD. OBJECTIVES: To review the use of laser therapy in the treatment of LE, scleroderma, sarcoidosis, and dermatomyositis. MATERIALS AND METHODS: A MEDLINE search was conducted to find articles detailing treatment of CTD with laser therapy. RESULTS: Thirty-nine published articles were identified. The outcomes and results of case reports were reviewed for each CTD when possible. CONCLUSIONS: Laser therapy offers novel and often effective treatment for recalcitrant cutaneous conditions in LE, scleroderma, sarcoidosis, and dermatomyositis. Review of the literature revealed a limited number of reports, many describing outdated technologies and techniques. It is therefore difficult to draw substantial conclusions regarding safety and the known association with photosensitivity. More-recent reports suggest that, with continued evolution of technology and understanding of CTD, lasers will have an expanding role in the treatment of cutaneous manifestations of CTD.
