Integration of RCM in the clinical and instrumental strategy for managing difficult pigmented lesions provided additional diagnostic information useful in the decision-making process.

Background: Increased skin Staphylococcus aureus colonization is frequently found in atopic patients. The reduction of local overinfection decreases skin inflammation and improves the flares. Objective: To evaluate the effectiveness of the antimicrobial activity of a silk fabric (MICROAIR DermaSilk®) coated with alkoxysilane quaternary ammonium with durable antimicrobial properties (AEGIS AEM 5572/5) in children affected by atopic dermatitis (AD). Methods: Sixteen children, 12 affected by AD with symmetric eczematous lesions on the antecubital areas and 4 without any cutaneous disease, used, for 7 days, tubular arm covers made of this special silk fabric but only one of each pair was coated with AEGIS AEM 5572/5. Microbiological examinations were done with standard cultural swabs and by means of quantification of bacterial agents using agar plates at baseline, after 1 h and after 7 days. Results: After 7 days a significant improvement in the mean value of the ‘local SCORAD’ index was observed in both the covered areas compared to the values obtained at baseline. The reduction in the mean number of colony forming units per square centimetre was similar in both areas. Conclusions: Although this special silk fabric seems to be able to improve skin lesions in AD, we were unable to demonstrate that such silk fabrics coated with AEGIS AEM 5572/5 have an antibacterial activity in vivo, as shown in vitro.

Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease which usually starts during the first years of life. In the management of AD, the correct approach requires a combination of multiple treatments to identify and eliminate trigger factors, and to improve the alteration of the skin barrier. In this article we try to explain the importance of skin care in the management of AD in relation to the use of textiles: they may be useful to improve disrupted skin but they are also a possible cause of triggering or worsening the lesions. Garments are in direct contact with the skin all day long, and for this reason it is important to carefully choose suitable fabrics in atopic subjects who have disrupted skin. Owing to their hygienic properties fabrics produced from natural fibres are preferential. Wool fibres are frequently used in human clothes but are irritant in direct contact with the skin. Wool fibre has frequently been shown to be irritant to the skin of atopic patients, and for this reason wool intolerance was included as a minor criterion in the diagnostic criteria of AD by Hanifin and Rajka in 1980. Cotton is the most commonly used textile for patients with AD; it has wide acceptability as clothing material because of its natural abundance and inherent properties like good folding endurance, better conduction of heat, easy dyeability and excellent moisture absorption. Silk fabrics help to maintain the body temperature by reducing the excessive sweating and moisture loss that can worsen xerosis. However, the type of silk fabric generally used for clothes is not particularly useful in the care and dressing of children with AD since it reduces transpiration and may cause discomfort when in direct contact with the skin. A new type of silk fabric made of transpiring and slightly elastic woven silk is now commercially available (Microair Dermasilk) and may be used for the skin care of children with AD. The presence of increased bacterial colonization has been demonstrated in patients with AD. Such colonization has been included in the group of trigger factors for eczema in AD. Silver products have recently been demonstrated to offer two advantages in the control of bacterial infections. Textiles may be used not only for clothes, but also to prevent dust mite sensitization in atopic patients. A marked clinical improvement of AD was observed in a group of adults and children with positive skin tests (not necessarily towards mites), after an intensive eradication programme for mite allergens. Skin treatment with acaricide and house dust mite control measures can decrease AD symptoms. Different textiles have various potential worsening links with allergies: e.g. clothing has been proposed as an additional source of exposure to mite and cat allergens. On the other hand, special textiles can be used to prevent dust mite sensitization.

More skin cancer monitoring is needed at tanning centres, and educational campaigns should be promoted, especially for young women and subjects at high risk of melanoma.

We performed a retrospective study covering a 10-year period (January 1997-January 2007) on children referred to our unit or followed up for Becker's nevus (BN). The aim of this study was to better define the characteristics of BN in childhood, when this hypermelanosis is more frequent than the limited number of studies might suggest. Our data show that BN in children has predilection sites similar to those in adults, but hypertrichosis is rarer. Sun exposure does not appear to play an etiopathogenetic role. The higher incidence in men reported in adult case studies was not found in children. During and after puberty, androgenic stimulation is known to play a pathogenetic role in BN, especially in men, but our cases were mostly younger than 6 years old.

Background: It is believed that vitiligo has an impact on the overall patient quality of life (QoL). Objective: To estimate QoL in a fairly large sample of Italian vitiligo patients by using the Dermatology Life Quality Index (DLQI) questionnaire. Methods: One hundred and sixty-one vitiligo patients referred to 9 dermatological centers were offered to participate by filling in the Italian version of the DLQI questionnaire. Results: The mean total DLQI score was 4.3 (SD ±4.9; range: 0-22). In multivariate analysis, DLQI >5 was associated with female gender, stability of the disease over time and involvement of the face at disease onset. Conclusions: The impairment of QoL is overall limited in Italian vitiligo patients, especially if it is compared with results from other available studies. This could be due to cultural and ethnic characteristics of the sample.

This study aimed to evaluate the prevalence of sunbed use among teenagers and the association between familial behavior and the adoption of UV-protective practices in this age group. We also assessed the impact of an educational program on students’ knowledge about the potential risks of sunbed use. The educational intervention focused on: (i) skin effects of UV radiation, (ii) photoaging and photocarcinogenesis, (iii) risk factors for skin cancer, (iv) indoor sun tanning and misleading concepts such as possible protective effect of sunbed use on skin cancer risk, (v) sun protection and relation with skin phototype, and (vi) early diagnosis of melanoma using the ABCDE check list and the ugly duckling sign. We carried out a survey of 3098 students and found a strong association between parental sunbed use and students’ use of the same (P < 0.0001). Students who attended the educational intervention were more aware that sunbed use cannot prevent sunburns (P = 0.03) than those who did not attend, making adjustments for confounding variables. However, sunbed use by parents influenced the desire to use a sunbed more than participation in the educational intervention (P < 0.0001). In conclusion, although our results indicate that educational interventions can improve knowledge of the risk of sunbed use. They also reveal a strong correlation between sunbed use by teenagers and parental behavior that highlights the importance of educational interventions involving families.
