ÖzetLazer kutanöz lezyonlarda uzun yıllardan beri kullanılmaktadır. Fraksiyonel termoliz kavramının gelişmesi ile de bu kullanım alanları giderek artmış ve artmaya devam etmektedir. Sıklıkla kullanıldığı alanlar arasında vasküler, pigmente lezyonlar, istenmeyen kılların yok edilmesi (lazer epilasyon), tatuaj çıkarılması, cilt yenileme tedavileri sayılabilir. Bu derlemede lazerin alopesi, vitiligo, psoriasis, verrü gibi rutine göre daha az tercih edilen dermatolojik uygulamalarından bahsedilecektir. (Türk derm 2012; 46 Özel Sayı 1: 52-5) Anah tar Ke li me ler: Lazer, dermatoloji, diğer kullanım alanları Sum maryLaser has been used for cutaneous lesions for a long time. The applications have gradually increased and continue to increase with the development of fractional thermolysis. It is often used for dermatological fields including vascular, pigmented lesions, unwanted hair removal (laser hair removal), tattoo removal and skin rejuvenation. In this review, dermatological applications with lasers which are less favored than routine such as alopecia, vitiligo, psoriasis, warts favored are discussed.

“…Recently, there has been a great interest in the potential treating role of laser and light-based therapies in various disorders including AA [67][68][69]. A study which investigated the efficacy of pulsed diode laser (904 nm) in the treatment of resistant patchy AA reported a regrowth rate in 94% of the patients, while no response was shown in control patches [68].…”

Alopecia areata (AA) is a common and complex T-cell-mediated inflammatory disorder. It may be patchy (localized), involve the entire scalp (alopecia totalis) or entire body (alopecia universalis). Alopecia totalis and universalis are often difficult to treat. Although many therapeutic options currently exist in alopecia areata, none of them are curative or preventive. Besides, none of them are approved by Food and Drug Administration (FDA). The disease unfortunately has an unpredictable course. The factors indicating a poor prognosis are the extent of hair loss at the presentation, long duration of the disease, and ophiasis pattern of hair loss. There are only a few randomized controlled studies conducted on recalcitrant AA. Recent research on immunology of hair follicle and recent developments in immunopathogenesis, together with the shared pathways of the disease with other autoimmune disorders, led investigators to focus on novel therapies that target specific immunological pathways. Herein, we will review shortly the current treatment options in recalcitrant alopecia areata based on recently published studies and then will focus on the recently developed broad-spectrum and targeted therapeutics.

“…The success rate was reported to be very high with regrowth observed in 94% of the patches, while no regrowth was seen in the control patches. 39 A similar study was recently performed with pulsed infrared diode laser on 23 patients with 52 AA patches resistant to conventional treatment modalities. 40 Favorable outcomes were also observed, in which significant hair regrowth was seen in the treated patches compared to the control patches.…”

“…A study in 2006 has reported the effectiveness of low-level pulsed infrared diode laser (904 nm) in the treatment of 16 patients with 34 AA patches non-responsive to conventional treatment modalities. 39 The patients received four treatments on a weekly basis, for a total of one month, with parameters of 04/s, 1.2 mW. The success rate was reported to be very high with regrowth observed in 94% of the patches, while no regrowth was seen in the control patches.…”

Alopecia areata (AA) is a complex autoimmune disease characterized by round or oval patches of non-scarring hair loss that is mediated by lymphocytes affecting the hair follicles. To treat localized AA, intralesional corticosteroid injections and topical corticosteroids are most commonly used, while for widespread AA, systemic steroids, immunosuppresants, and contact immunotherapy are commonly considered. However, therapeutic options for refractory AA that is unresponsive to these conventional treatments are limited. Various lasers have been suggested in recent studies to treat AA. The effect of 308-nm excimer laser was the most studied, while others, including neodymium-doped yttrium aluminum garnet, erbium:glass laser, fractional CO2 laser, and low-level laser therapy, have also been assessed. Despite the nascent state of research on lasers as a treatment option for AA, there have been a great deal of promising results. It is possible for lasers to become the mainstay treatment option of AA. Key words
