BACKGROUND Phototherapy consists of exposure to ultraviolet radiation for therapeutic reasons. Radiation is already used in dermatological practice, and many studies have already proved the beneficial effect of UV light treatment for chronic inflammatory or lymphoproliferative skin diseases. The Dermatology Service of the Clinics Hospital of Porto Alegre (Hospital de Clínicas de Porto Alegre) h...

We compared the clinical efficacy of a short-term intervention of 308-nm excimer laser with that of narrow-band UVB (NBUVB) phototherapy for vitiligo patients to see the early response. Twenty-three symmetrically patterned patches of vitiligo on 8 patients were selected. Vitiligo patches on one side of the body were treated 2 times per week for a maximum of 20 treatments with the excimer laser,...

BACKGROUND Phototherapy is believed to be a safe method for the management of hyperbilirubinemia. However, there are some controversial issues regarding the genotoxic effects of phototherapy on DNA. The aim of this study was to investigate morphologically both phototherapy-induced DNA double-strand breaks (DSBs) and apoptosis in lymphocytes derived from jaundiced and non-jaundiced neonates. M...

BACKGROUND Despite a long period of development, there are still considerable variations in the spectral output, the levels of irradiance, and irradiated area provided by commercial phototherapy systems. These variations depend on the types and output of the lamps used to produce the phototherapy, along with the design of the systems, and principally on whether the phototherapy is provided from...

BACKGROUND UVA1 phototherapy has recently demonstrated high levels of efficacy and tolerability for treating a variety of inflammatory and neoplastic skin diseases. OBJECTIVE The purpose of the present study was to assess the clinical efficacy of UVA1 (340~400 nm) phototherapy for treating pityriasis rosea and to assess the course of the disease after treatment. METHODS Fifteen patients wit...

In this randomized, controlled non-inferiority trial, filtered sunlight was compared with conventional phototherapy for the treatment of hyperbilirubinemia in term and latepreterm neonates. The primary end point was efficacy, which was defined as a rate of increase in total serum bilirubin of less than 0.2 mg/dL/h for infants up to 72 hours of age or a decrease in total serum bilirubin for infa...

BACKGROUND AND OBJECTIVES Phototherapy with low intensity laser irradiation has shown to be effective in promoting the proliferation of different cells. The aim of this in vitro study was to evaluate the potential effect of laser phototherapy (660 nm) on human dental pulp stem cell (hDPSC) proliferation. STUDY DESIGN/MATERIALS AND METHODS The hDPSC cell strain was used. Cells cultured under n...

Background: Hyperbilirubinemia in newborn is quite common. Phototherapy (PT) one of the most common noninvasive methods for treatment this hyperbilirubinemia. There are limited studies available on effect PT platelet count with contrasting results. So, study was conducted to determine phototherapy counts hyperbilirubinemic neonates tertiary care hospital. Methods: This a hospital based prospect...

BACKGROUND Despite an understanding of the enzymatic pathways leading to bilirubin production and degradation, very few pharmacologic interventions are utilized and the mainstay of treatment remains phototherapy. AIMS To evaluate the efficacy of clofibrate in reducing total serum bilirubin levels in late pre-term neonates with non-hemolytic jaundice. DESIGN AND SETTING Double-blind, placebo...

Introduction:The aim of this study is to compare significant post-phototherapy bilirubin rebound in two groups of neonates, with two levels of bilirubin, at discontinuation of phototherapy. Materials and Methods:One hundred and fifteen neonates ≥35 weeks of gestationl age (GA), admitted due to hyperbilirubinemia in the Neonatal Ward of Valiasr Hospital, were randomly divided into two groups: gr...
