Abstract: Summary These guidelines for use of narrowband (TL-01) ultraviolet B have been prepared for dermatologists by the British Photodermatology Group on behalf of the British Association of Dermatologists. They present evidence-based guidance for treatment of patients with a variety of dermatoses and photodermatoses, with identification of the strength of evidence available at the time of preparation of the guidelines, and a brief overview of background photobiology.

Abstract: BACKGROUND: While narrowband ultraviolet B (UVB) phototherapy is a well-established treatment for a range of skin conditions in adults, there is little in the literature about its use in children and data regarding its long-term carcinogenic potential are lacking. AIM: We undertook a retrospective review of the use of narrowband UVB phototherapy in a paediatric population attending two Glasgow Hospitals. METHODS: Phototherapy case notes for all children aged 16 years and under at time of treatment were reviewed at two hospital sites between 1996 and 2002. RESULTS: In total, 77 children had been treated (median age 12 years, range 4-16). The conditions treated most frequently were psoriasis (45%) and atopic eczema (32%). Other dermatoses treated included alopecia areata, acne, hydroa vacciniforme and polymorphic light eruption. Treatment courses for atopic conditions were longer than those required for psoriatic conditions: median number of treatments 24 for atopic eczema (range 3-46), and 17.5 for psoriasis (range 9-35). By the end of treatment, 68% of the atopic patients and 63% of the patients with psoriasis had cleared. The adverse event profile was similar to that in adults, with erythema, herpes simplex reactivation and PLE all recorded. Anxiety was a problem for five patients. CONCLUSION: We conclude that narrowband UVB phototherapy is a useful and well-tolerated treatment for children with severe or intractable inflammatory skin disease, but concerns remain regarding long-term side-effects.

Abstract: A new technique is described for automated ultraviolet dosimetry within whole-body phototherapy cabinets. A dual-head detector system has been designed, permitting simultaneous assessment of irradiance levels and radiant intensities from individual lamps. One detector is used in combination with a diffuser/filter system for the measurement of irradiance and the other is mounted at the end of a slit collimator to provide a measurement which can be related to the radiant intensities of the individual lamps. These quantities are derived from 800 separate measurements made during rotation of the detector head around a 360 degrees circle at a fixed height and position within the cabinet under remote computer software control. The device has advantages compared with standard techniques, enabling measurements to be made without the need for a person to be present in the cabinet. A full set of measurements is made with minimal switching of the power supply to the lamps. This simplifies the assessment and reduces the uncertainty from variation in output after the lamps are switched on. Variations in irradiance with orientation for the smaller phototherapy cabinets are clearly demonstrated. Plots of data from the collimated detector show peaks corresponding to the lamps and the surrounding reflectors. The plots enable failed lamps to be detected and peak values can be related to radiant intensities of individual lamps.
