Suppression of UVB-induced Cutaneous Erythema by a Previous UVB Exposure¶

Photochemistry and Photobiology, 2001
People who vacation in sunny places are exposed to the sun on multiple occasions at least on a daily basis. The clinical assessment of sun exposure is erythema in the first 48 h after exposure and pigmentation at times greater than 3-5 days. The purpose of this investigations was to determine the extent to which consecutive erythemogenic exposures ...

UVB Photosensitivity due to Ranitidine

Dermatology, 2000
We describe a 62-year-old male with photosensitivity due to ranitidine. An oral challenge test after taking ranitidine with UVB irradiation was positive. Ranitidine-induced UVB photosensitivity was persistent even after cessation of the medication.

UVB phototherapy of atopic dermatitis

British Journal of Dermatology, 1988
UVB phototherapy of atopic dermatitis was investigated in two paired-comparison studies. In study I, 17 patients were treated for 8 weeks with ultraviolet B radiation (UVB) on one half of the body and with visible light (placebo) on the other. A severity score based on eight clinical variables was determined before, during and after treatment.

Phototherapie (UVB/Schmalspektrum UVB/UVA)

2003
Unter Phototherapie wird die Anwendung von UVB- oder UVA-Strahlung ohne zusatzliche Photosensibilisatoren zur Behandlung von Hautkrankheiten verstanden. Sie stellt als Alternative zu etablierten und zum Teil nebenwirkungsreichen, traditionellen Behandlungsformen eine immer wichtiger werdende Saule der modernen Therapie entzundlicher bzw.

Experience with UVB Phototherapy in Children

Pediatric Dermatology, 1996
Abstract: Twenty children age 14 months to 12 years with photoresponsive dermatoses were treated with ultraviolet B (UVB) phototherapy over four years. Ten children had psoriasis, five had pityriasis lichenoides, and five had atopic dermatitis. All received short courses (average 34 treatments) of phototherapy with either no maintenance or short ...

Photoageing: the role of UVB, solar-simulated UVB, visible and psoralen UVA radiation

British Journal of Dermatology, 1986
We have studied the morphological and histological effects of chronic exposure of two strains of haired mice (albino Balb/c and pigmented C3H-) to various types of radiation. UVB (280-320 nm) radiation from unfiltered sunlamp bulbs for 20 and 30 weeks produced marked epidermal acanthosis and dyskeratosis which was reversible in mice exposed for 20 ...

Acitretin in combination with UVB or PUVA

Journal of the American Academy of Dermatology, 1999
Combination therapy of psoriasis with acitretin and phototherapy (psoralen-ultraviolet A [PUVA] or ultraviolet B [UVB]) offers multiple advantages over use of either modality alone. As monotherapy, acitretin in doses of 50 mg/day is moderately effective, but is associated with numerous side effects.

UVB Maintenance Phototherapy in Psoriasis

International Journal of Dermatology, 1985
Abstract: Twenty‐six patients with generalized stable plaque‐type psoriasis were treated three to five times weekly with midwave fluorescent ultraviolet radiation (UVB) combined with either tar or lubricants. After clearing, patients received maintenance treatment with lubricant and UVB for a minimum of four weekly exposures, which were subsequently ...

UVB-based optogenetic tools

Trends in Biotechnology, 2015
Plant and algae photoreceptors that are sensitive to blue and red wavelengths have recently paved the way for the development of optogenetic tools [1]. These tools allow the manipulation and control of cellular signaling pathways with great specificity and fine spatial and temporal precision.
