Unconventional Use of Intense Pulsed Light

Abstract

According to the literature, intense pulsed light (IPL) represents a versatile tool in the treatment of some dermatological conditions (i.e., pigmentation disorders, hair removal, and acne), due to its wide range of wavelengths. The authors herein report on 58 unconventional but effective uses of IPL in several cutaneous diseases, such as rosacea (10 cases), port-wine stain (PWS) (10 cases), disseminated porokeratosis (10 cases), pilonidal cyst (3 cases), seborrheic keratosis (10 cases), hypertrophic scar (5 cases) and keloid scar (5 cases), Becker's nevus (2 cases), hidradenitis suppurativa (2 cases), and sarcoidosis (1 case). Our results should suggest that IPL could represent a valid therapeutic support and option by providing excellent outcomes and low side effects, even though it should be underlined that the use and the effectiveness of IPL are strongly related to the operator's experience (acquired by attempting at least one specific course on the use of IPL and one-year experience in a specialized centre). Moreover, the daily use of these devices will surely increase clinical experience and provide new information, thus enhancing long-term results and improving IPL effectiveness.

Characterization of blue light irradiation effects on pathogenic and nonpathogenic Escherichia coli

“…like acne (Dai et al, 2012;Dong et al, 2016;Liu et al, 2016;Maisch et al, 2014;Opel et al, 2015;Pei, Inamadar, Adya, & Tsoukas, 2015;Piccolo et al, 2014). Phototherapy employs visible light in the 400-700 nm wavelength range to activate either exogenous (as in photodynamic therapy-PDT) or endogenous photosensitizers (PSs) (Lambrechts, Demidova, Aalders, Hasan, & Hamblin, 2005;Maclean, Macgregor, Anderson, & Woolsey, 2008Nussbaum, Lilge, & Mazzulli, 2002;Orenstein et al, 1997).…”

Retrospective Analysis of 14 Cutaneous Sarcoidosis Patients with Clinical and Dermoscopic FeaturesRetrospective Analysis of 14 Cutaneous Sarcoidosis Patients with Clinical and Dermoscopic Features

“…Sistemik tedavi almayan iki hastanın toplam üç lezyonuna 1064 nm NdYAG lazer tedavisi uygulanmış fakat lezyonlarda klinik düzelme izlenememiştir. Literatürde "yoğun ışık kaynağı" ve "dye lazer" gibi ablatif olmayan lazerler ile tedavi olmuş kutanöz sarkoidoz olguları bildirilmiş olsa da (10,11) , NdYAG lazer ile sarkoidoz lezyonları gerilememiştir. 1064 nm NdYAG lazerin bu iki lazere göre derinin daha derin katmanlarına ulaşmasına rağmen, etkisiz kalması ya daha önce bildirilen olguların tesadüfi olduğunu göstermekte ya da verdiğimiz dozun yetersiz kaldığını göstermektedir.…”

Update on the Management of Rosacea

“…98 Parameter flexibility enables the targeting of deep vessels, as well as large areas of telangiectasia, erythema, and flushing, but does require clinical expertise and experience to perfect treatments and decrease complications. Most IPL systems provide a large spot size, reducing patient discomfort, increasing efficiency of treatment, and enabling deeper light penetration.…”

“…When used appropriately, IPL appears to provide impressive results in various settings with a relatively negligible side effect profile. [97][98][99][100][101][102][103][104][105][106][107][108][109][110][111] Early on, Angermeier demonstrated 75%−100% clearance after one or two treatments in 174 of 188 patients with vascular lesions at a 2-month follow-up. 99 Soon after, these same results were confirmed in a study specific to rosacea only.…”
