Spectrophotometric Measurement of Minimal Erythema Dose Sites after Narrowband Ultraviolet B Phototesting: Clinical Implication of Spetrophotometric Values in Phototherapy
BACKGROUND The spectrophotometer is well known to be a useful tool for estimating the objective minimal erythema dose (MED) during planning of phototherapy protocol. However, only a few spectrophotometric values are used to evaluate the erythema and pigmentation of the MED site during phototesting. OBJECTIVE To determinea new meaning of the relationships among spectrophotometric values during...
متن کاملIs it Useful to Calculate Minimal Erythema Dose Before Narrowband UV-B Phototherapy?
INTRODUCTION AND OBJECTIVES The starting dose for narrowband UV-B phototherapy is determined by a patient's skin phototype or minimal erythema dose (MED). Calculation of MED identifies patients with unsuspected photosensitivity. The aim of this study was to investigate the influence of factors such as concomitant use of photosensitizing agents, diagnosis, and combination with acitretin in patie...
متن کاملLowered ultraviolet minimal erythema dose in hemiplegia.
In view of recent reports of increased tanning in hemiplegic limbs, we have investigated ultraviolet (u.v.) minimal erythema dose (MED) in hemiplegia using the bilateral comparison technique. Seven of 10 patients had a lower MED in the hemiplegic arm compared to the normal side, the mean reduction being 16% (range 0-33%, P = 0.003). No patients had a higher MED in the hemiplegic arm. We review ...
متن کاملThe relationship of skin type with minimal erythema dose (MED)
Background: Phototherapy is an important modality in dermatology and the number of skin diseases which can be controlled with it is increasing. In order to start treatment, the first dose of phototherapy is determined by measurement of minimal erythema dose (MED) in each patients individually or according to patient’s skin type. Objective: To determine the relationship of skin type with MED in ...
متن کاملDisseminated Superficial Actinic Porokeratosis in a Patient with Psoriasis, after Long-Term Narrowband Ultraviolet B Phototherapy
Porokeratosis is a rare epidermal disorder characterized by annular or linear hyperkeratotic plaques with slightly raised thread-like borders, and in most cases, atrophic centers. Disseminated superficial porokeratosis and disseminated superficial actinic porokeratosis (DSAP), which primarily involve sun-exposed areas, are common types of porokeratoses. Histologically, a column of parakeratotic...
