Background The efficacy and safety of biologic and phototherapy in treating moderate-to-severe psoriasis is well known. However, some patients may not respond well to biologic agents or phototherapy on their own and may require combination therapy. Skillfully combining a biologic agent and phototherapy may provide an additive improvement without much increase in risks. Objective To summarize ...
Background & Aims: This study was conducted to compare the efficacy of intermittent and continuous phototherapy.Materials & Methods: This controlled randomized clinical trial study was performed on 96 full-term neonates admitted in the neonatal ward of Besat hospital of Hamadan city with indirect hyperbilirubinemia. The neonates were randomly divided into two groups. Continuous phototherapy gr...
position changes are believed to increase the efficacy of phototherapy and this practice is routinely used in all neonatal departments in our country. the aim of this study was to determine the effect of routine turning on the total serum bilirubin (tsb) concentration versus only supine position. in a randomized clinical trial fifty healthy term jaundiced neonates who were admitted to the neona...
Background: Phototherapy is the most effective and commonly used treatment for neonatal jaundice, which reduces the need to exchange transfusion. Today, phototherapy is widely used even in unnecessary cases; however, clinicians who use phototherapy should be aware of the possible adverse effects of this treatment to avoid unnecessary use of it. Therefore, this study aimed to evaluate the relati...
INTRODUCTION This study aims to assess the usefulness of day 3 (49 to 72 hours) pre-phototherapy total serum bilirubin (TSB) in predicting subsequent significant hyperbilirubinaemia (SHB) and the feasibility of early discharge for term and near-term glucose-6-phosphate dehydrogenase (G6PD) deficient newborns. MATERIALS AND METHODS This prospective cohort study involved in born G6PD deficient ...
OBJECTIVE We tested the hypothesis that LED phototherapy with combined 660-nm and 890-nm light will promote healing of venous ulcers that failed to respond to other forms of treatment. BACKGROUND DATA A variety of dressings, growth factors, and adjunct therapies are used to treat venous ulcers, but none seems to yield satisfactory results. MATERIALS AND METHODS We used a randomized placebo-...
OBJECTIVE The objective of this work was a further investigation of redox mechanisms of laser phototherapy on the cellular level. BACKGROUND DATA Cytochrome c oxidase, the terminal enzyme of the mitochondrial respiratory chain, is believed to work as the photoacceptor to modulate cellular metabolism in laser phototherapy. MATERIALS AND METHODS The changes in the absorption spectra of HeLa-c...
The purpose of the present paper is to provide our data on the effects of phototherapy on peripheral nerve recovery. The aim is to call attention to an issue that still requires much research to elucidate the biological mechanisms through which phototherapy exerts its effects on nerve tissue, and to provide clinicians with the basis for planning clinical trials on the use of phototherapy for en...
OBJECTIVE To measure the irradiance in humidified incubator under three different overhead phototherapy devices. DESIGN/METHODS The effective irradiance of three phototherapy devices was assessed by taking a series of irradiance measurements in the illuminated field. Measurements were made with a fixed bandwidth broadband radiometer (380-530 nm). The distance between the light source and the ...
