DUH: dyschromatosis universalis hereditaria IPL: intense pulsed light INTRODUCTION Characterized by hyperpigmented and hypopigmented macules forming a reticulate pattern, dyschromatosis universalis hereditaria (DUH) was first described by Toyamo in Japan. Subsequent cases have been reported from other areas including Europe, China, Saudi Arabia, Tunisia, India, and Nigeria. A variable autosomal...

PURPOSE To promote awareness and prevention of ocular damage that can occur during Intense Pulsed Light (IPL) treatments of the periocular areas. METHODS A retrospective chart review was conducted of 2 cases involving ocular damage following IPL procedures that were treated at Bascom Palmer Eye Institute for ocular complications. Routine data were collected during ophthalmic examinations. R...

OBJECTIVE Cutaneous telangiectases are a characteristic and psychologically distressing feature of SSc. Our aim was to assess the efficacy of two light-based treatments: pulsed dye laser (PDL) and intense pulsed light (IPL). METHODS Nineteen patients with facial or upper limb telangiectases underwent three treatments with PDL and IPL (randomly assigned to left- and right-sided lesions). Outco...

Intense pulsed light (IPL) annealing of graphene inks is demonstrated for rapid post-processing of inkjet-printed patterns on various substrates. A conductivity of ≈25,000 S m(-1) is achieved following a single printing pass using a concentrated ink containing 20 mg mL(-1) graphene, establishing this strategy as a practical and effective approach for the versatile and high-performance integrati...

The aim of this study was to determine the effects of intense pulsed light (IPL) on cell proliferation and the secretion of vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) in human fibroblasts and vascular endothelial cell lines, and to investigate the effects of IPL on the mRNA expression levels of type I and III procollagens in cultured human fibroblasts. Foresk...

The objective of this work is the investigation of intense pulsed light (IPL) photoepilation using Monte Carlo simulation to model the effect of the output dosimetry with millisecond exposure used by typical commercial IPL systems. The temporal pulse shape is an important parameter, which may affect the biological tissue response in terms of efficacy and adverse reactions. This study investigat...

BACKGROUND A rising number of laser- or light-based therapies are addressing the need for effective acne treatments with minimal downtime. OBJECTIVE The purpose of this study is to evaluate an intense pulsed light (IPL) equipped with a 530- to 750-nm filter for inflammatory acne treatment. PATIENTS AND METHODS Thirty female patients (mean age, 25.7 years) with mild-to-moderate acne were enr...
