BACKGROUND/AIMS Chronic kidney disease (CKD) patients on dialysis are prone to vitamin D insufficiency despite oral vitamin D supplementation. Here, we studied whether narrow-band ultraviolet B (NB-UVB) exposures improve vitamin D balance. METHODS 14 haemodialysis patients and 15 healthy subjects receiving oral cholecalciferol 20 µg daily got nine NB-UVB exposures on the entire body. Serum 25...
Scrotal dermatitis is a very common condition that has been easily overlooked by most dermatologists and treating physicians. The condition is easily mistaken for the common skin disorders affecting the area, like fungal infections. Scrotal dermatitis is not considered a separate disease entity and is usually considered a condition similar to the contact dermatitis occurring elsewhere. This art...
Palmoplantar psoriasis (PPP) presents with typical scaly patches sometimes studded with sterile pustules. It is chronic and recalcitrant to therapy; it often causes itching, burning, painful ragades and can lead to severe disabilities (1). Some preliminary works (2-4) have established that an excimer laser-generated 308 nm UVB radiation is effective in the treatment of psoriasis. In our study, ...
The activation of endogenous double-stranded RNA (endo-dsRNA) signalling pathways is linked to a variety autoimmune diseases. Here, we investigated the role dsRNA in psoriasis by quantifying binding protein (DRBP) mRNA and mitochondrial formation response narrow-band UVB (NB-UVB) treatment. RNAseq data from 34 psoriatic patients treated with NB-UVB were analysed. Biopsies obtained four sites 24...
The spectral irradiance of narrow band and broad spectrum radiation sources have been measured and the erythemally effective irradiance calculated by weighting the spectral irradiance of each source by an erythema action spectrum for human skin and integrating over the range of wavelengths in each spectrum. The ratio of the erythemally effective irradiances determined in this manner have been c...
Abstract Sunlight‐originated ultraviolet B (UVB) rays influence daily life in both beneficial and detrimental ways, depending upon light power exposure time. Therefore, precise timely UVB irradiance control is of great importance to humans. This study proposes a self‐powered wearable zinc sulfide (ZnS) nanoparticle (NP)‐based UVB‐C detector for the situ monitoring levels ambient environments. T...
BACKGROUND Atopic dermatitis (AD) is a common inflammatory skin disease exhibiting a predominantly T(H)2/"T22" immune activation and a defective epidermal barrier. Narrow-band UVB (NB-UVB) is considered an efficient treatment for moderate-to-severe AD. In patients with psoriasis, NB-UVB has been found to suppress T(H)1/T(H)17 polarization, with subsequent reversal of epidermal hyperplasia. The ...
