Self-detected cutaneous melanomas in Italian patients.

Self-detection of suspicious pigmented skin lesion combined with rapid referral to dermatologic centres is the key strategy in the fight against melanoma. The investigation of factors associated with pattern of detection of melanoma (self- vs. nonself-detection) may be useful to refine educational strategies for the future. We investigated the frequency of melanoma self-detection in a Mediterranean population at intermediate melanoma risk. A multicentric survey identified 816 consecutive cases of cutaneous melanoma in the period January to December 2001 in 11 Italian clinical centres belonging to the Italian Multidisciplinary Group on Melanoma. All patients filled a standardized questionnaire and were clinically examined by expert dermatologists. Self-detected melanomas were 40.6%, while the remaining lesions were detected by a dermatologist (18.5%), the family physician (15.2%), other specialists (5%), the spouse (12.5%), a friend or someone else (8.2%). Variables associated with self-detected melanomas were female sex, young age, absence of atypical nevi, knowledge of the ABCD rule, habit of performing skin self-examination. Self-detected melanomas did not differ from nonself-detected tumours in term of lesion thickness; however, patients with self-detected melanomas waited a longer period before having a diagnostic confirmation (patient's delay) (> 3 months: odds ratio, 3.89; 95% confidence interval, 2.74-5.53). In order to reduce the patients' delays, educational messages should adequately stress the need for a prompt referral to a physician once a suspicious pigmented lesion is self-detected.

Eyelid dermatitis: an evaluation of 150 patients.

This study was performed to evaluate eyelid dermatitis in a group of patients of our Allergy Unit between January 1990 and April 1991. Among the 1158 patients seen during this period, 150 had eyelid dermatitis: 135 females and 15 males, with a mean age of 35 years. Of the 150 patients with eyelid dermatitis, 54 had eczema localized to the eyelids only, 49 to the eyelids and face, 19 to the eyelids and hands, and 28 to the eyelids and other sites. 98 patients (65.3%) were diagnosed as having allergic contact dermatitis, 25 (16.6%) irritant contact dermatitis, 21 (14%) atopic dermatitis, and 6 (4%) seborrhoeic dermatitis. Patch test reactions to nickel sulphate, Kathon CG and fragrance-mix occurred more frequently in patients with eyelid dermatitis than in those without.

Alopecia areata and interleukin-2 receptor.

Interleukin-2 (IL-2) is a lymphokine produced by activated T cells and its receptor (IL-2R) is expressed on T cells; one of the IL-2R components can be measured as a soluble serum protein (sIL-2R). Levels of sIL-2R were measured as a sign of T cell activation in serum of 12 patients suffering from alopecia areata (totalis or universalis) and in a group of healthy control subjects. An enzyme-linked immunosorbent assay was used to determine the levels of sIL-2R in blood samples drawn during both the active and resting phase of the disease. In patients with alopecia areata in active phase the sIL-2R concentrations were significantly higher than in stable phase and in controls. The biologic role of sIL-2R is still unknown, but one could speculate that T lymphocyte activation with subsequent secretion of IL-2 and IL-2R expression may contribute to the immune inflammatory mechanism of alopecia areata.
