Narrow band UVB phototherapy in dermatology.
The first report of the use of ‘phototherapy’ in the treatment of skin disorders dates from 1400 BC from India when patients with vitiligo were given certain plant extracts (whose active ingredients included psoralens) and then exposed to the sun. The real interest in the use of ultraviolet (UV) irradiation in the treatment of various skin diseases started in the 19 century when Niels Finsen re...
متن کاملNarrow-band red light phototherapy in perennial allergic rhinitis and nasal polyposis.
BACKGROUND Allergic rhinitis and nasal polyposis are common nasal diseases, but the available treatment modalities have only limited success. OBJECTIVE To assess the therapeutic effect of low-energy narrow-band red light phototherapy on nasal clinical symptoms of allergic rhinitis and nasal polyposis. METHODS In a double-blind randomized prospective study, 50 patients with allergic rhinitis...
متن کاملDesign of spectrum equalization filter for SLED light source
This paper considers the use of an all-fiber Mach–Zehnder interferometer (MZI) to equalize the output spectrum of a super-luminescent light emitted diode (SLED). A minimax approach and a window integration approach are proposed to design spectrum equalization filters with pre-specified performance indices. To present the proposed design approaches, a single stage MZI is used as an illustrative ...
متن کاملNew light source for narrowband UVB phototherapy puts patients at risk
Since its introduction in 1988, the Philips TL01 fluorescent tube has been used successfully and safely in phototherapy for many skin diseases (3-6). A major advantage was that burning of patients could be effectively controlled compared to existing photochemo-therapy modalities and broadand small-spectrum UVB treatments.This led to 311 nm irradiation becoming the treatment of choice for condit...
متن کاملThe Alexandrite Ring Laser: A Spectrally Narrow Lidar Light Source for Atmospheric Fluorescence and Absorption Observations
The Atmospheric Lidar Observatory (ALO) at Utah State University has recently acquired an alexandrite laser, developed by Light Age Incorporated, that is a relatively new type of configuration, ideal for resonance lidar and DIAL observations. Unidirectional ring lasing is established in a tworod cavity, producing single longitudinal and transverse mode (TEM00) pulses up to 200 mJ in energy and ...
