“…Testing for immediate dermographism consisted of stroking the skin of the upper part of the back with a calibrated dermographometer at a pressure of 3 kg/cm- (Fig, I) (15). Two perpendicular 1.5 cm lines were drawn on the upper baek, 3 times each, just at the upper border of the scapula.…”

Studies report that urticarial dermographism is exacerbated by "life events" and emotions. The aim of this study was to determine what aspects of life quality are affected by symptomatic dermographism and whether acute stress is a potential triggering factor. A total of 21 adult patients with urticarial dermographism completed a questionnaire on symptoms and quality of life. Twelve patients agreed to enrol in the study, which involved provocation by prick test and dermographism before and after a standardized psychosocial stress test (Trier Social Stress Test). Seventeen age-matched controls underwent corresponding tests. Of the patients answering the questionnaire, 43% reported that their disease had an impact on their quality of life and 33% that psychosocial stress precipitated the symptoms. However, the dermographic reaction in patients with urticaria factitia was not significantly intensified after the stress test. We conclude that the acute psychosocial stress test does not alter the magnitude of the dermographic reactions.

“…It is now possible to measure the weal size in response to different pressure and on different sites of the body, and therefore compare the reduction of the weal size by different substances (James & Warin, 1969).…”

Dermographism: reduction in weal size by chlorpheniramine and hydroxyzine

et al. 1973

Regular measurements of the weal size produced by known trauma have been carried out in a series of patients with symptomatic dermographism. The degree of reduction of the weal has been compared after 2 weeks’treatment with chlorpheniramine and hydroxyzine pamoate administered in a double blind manner to thirty‐three patients. The doses given were those in common usage and usually well tolerated by patients, namely chlorpheniramine 4 mg three times daily and hydroxyzine pamoate 25 mg three times daily. Hydroxyzine gave a statistically greater reduction of weal size and was also clinically preferred. Hydroxyzine is a weak antihistamine and its mode of action on weal production is unknown, but its clinical efficacy is not likely to be due to its sedative effects. Statistical proof is given to the observation that weals on exposed sites are smaller than those provoked in areas of skin normally covered.

“…The degree of pruritus over the proceeding 24 h was graded using a 10 cm visual analogue scale and the width of a weal 2 min after elicitation on the upper back, using a dermographometer set at constant pressure, was measured (James & Warin, 1969).…”
