Summary
Narrowband UV-B therapy effectively induces light tolerance in solar urticaria patients. This safe treatment approach significantly improves patient-reported outcomes and disease activity.
Area of Science:
- Dermatology
- Photomedicine
- Immunology
Background:
- Solar urticaria is a rare photodermatosis.
- Antihistamines are the primary treatment.
- UV phototherapy is a second-line option for inducing light tolerance.
Purpose of the Study:
- To evaluate a narrowband UV-B desensitization protocol for solar urticaria.
- To assess treatment effectiveness and patient outcomes.
Main Methods:
- Retrospective study of 8 solar urticaria patients.
- Narrowband UV-B therapy administered in short courses (<20 sessions).
- Skindex-29 and custom questionnaires used for outcome assessment.
Main Results:
- No adverse events or flares reported during treatment.
- 6 out of 8 patients reported satisfactory outcomes.
- Significant improvement (>20%) in Skindex-29 scores for 78.6% of patients.
Conclusions:
- Narrowband UV-B phototherapy is a safe and effective treatment for solar urticaria.
- High percentage of patients achieve light tolerance and symptom improvement.
- This protocol offers a viable option for managing solar urticaria.

01:30UV–Vis Spectrum
2.1K
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...

3.7K
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

01:16Induction
5.7K
An emf is induced when the magnetic field in a coil is changed by pushing a bar magnet into or out of the coil. emfs of opposite signs are produced by motion in opposite directions, and the directions of emfs are also reversed by reversing poles. The same results are produced if the coil is moved rather than the magnet—it is the relative motion that is important. The faster the motion, the greater the emf. Additionally, there is no emf when the magnet is stationary relative to the coil.

02:16Light Acquisition
9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

01:24Self-Inductance
3.1K
Mutual inductance arises when a current in one circuit produces a changing magnetic field that induces an emf in another circuit. On the other hand, self-inductance arises when the current passing through the circuit changes, creating a changing magnetic flux, resulting in inductance in the same circuit.
Consider a circuit connected to an AC source. As the current varies with time, the magnetic flux through the circuit correspondingly changes. Faraday's law tells us that an emf would...
