“…Several studies including hairdressers have also shown a significant and early high risk of developing ACD during the first years of starting their jobs 14‐17 . Moreover, although the association between contact allergy and atopic dermatitis remains controversial in the literature, 18‐21 34.7% of our patients reported a positive personal history of atopic disease.…”

Background Oxidative hair dyes are an important source of chemical exposure and a major risk factor for the development of occupational and non‐occupational allergic contact dermatitis (ACD) worldwide. Objective To identify the frequency of common allergens associated with occupational and non‐occupational ACD to hair dyes during the last 10 years, in Greece. Methods We retrospectively reviewed the medical records of patients with suspected ACD to hair dyes from 2010–2019. All patients with patch‐test‐confirmed ACD to hair dyes were evaluated. Results Out of 501 patients with suspected ACD to hair dyes, 362 had at least one positive reaction to hair dye allergens (62.4% were customers and 37.6% were hairdressers). The mean age of customers and hairdressers was 43.8 years and 30.8 years, respectively. Of the customers, 58.9% were exposed to dyes for >10 years and 61% of hairdressers for <5 years. The most common site of ACD among customers was the scalp (85%) and among hairdressers the hands (90%). p‐Phenylenediamine (PPD) was the most common contact allergen (52.2%), followed by toluene‐2,5‐diamine, p‐aminophenol, m‐aminophenol, and ammonium persulfate. Conclusions Sensitization prevalences for PPD and cross‐reacting allergens have increased in Greece during the last decade, regardless of occupational or non‐occupational exposure to hair dyes.

“…The disruption of the skin barrier in AD patients raises the possibility of both sensitization and irritation, which could explain the increased prevalence of contact dermatitis that finally exert a detrimental effect also to AD (Teo, McFadden, White, Lynch, & Banerjee, ). The diagnosis of contact dermatitis in all patients but especially in AD patients should be conducted following the recently available Italian Guidelines in Patch Testing—adapted from the European Society of Contact Dermatitis (Stingeni et al, ).…”

Atopic dermatitis (AD) therapeutic approach calls for a long‐term treatment. Treatment options for AD have recently undergone a revolutionary change by the introduction of the first biologic drug. Availability in daily practice of the last version of international AD guidelines, taking peculiarities of the country into account, can contribute to good clinical practice in Italy. To adapt European Dermatology Forum (EDF) guidelines for AD to the Italian medical–legal context, the EDF guidelines were assessed independently by two independent Italian renowned experts in the field and further integrated with articles published and systematically reviewed before May 2019. The first draft was collegially corrected and updated by the members of the SIDEMAST, ADOI, and SIDAPA. Recommendation levels (A; B; C; D) were graded based on the evidence levels (1–4). The adapted guidelines presented here focus on topical and systemic therapies in AD patients, both children and adults. As opposed to previous Italian guidelines, they include indications about biologics. New relevant evidence available from very recent literature and peculiarities of the Italian medical and legal context have been integrated in the revision process. If compared to general guidelines for AD not adapted to a specific national and cultural context, a revision for specific Italian needs is now available: It comprises the option of implementing the new biologic treatments and is likely to provide an important contribution to the improvement of clinical practice in Italy. Cooperation between patients, dermatologists, allergologists, and pediatricians remains mandatory in AD management. The authors of the present revision recommend an update of the Italian guidelines to be performed at least every second year.

“…Hypothetically, as recently suggested for FLG loss‐of‐function mutations, a pathway that unites the airways and the skin could be responsible for primary respiratory sensitization to aeroallergens being demonstrated by patch testing.

Background The diagnostic significance of the atopy patch test for the management of dermatitis possibly triggered by aeroallergens is still controversial. However, sufficiently large studies with routinely tested standardized aeroallergen patch test preparations in dermatitis patients are lacking. Objective To evaluate the reaction frequency and the reaction profiles of 10 until mid‐2015 commercially available, standardized aeroallergen patch test preparations of the ‘Stallerpatch’ test series (Stallergenes, Antony Cedex, France) in a large multicentre patient cohort. Methods A retrospective data analysis of patients with suspected aeroallergen‐dependent eczematous skin lesions was performed, who were patch tested in 15 Information Network of Departments of Dermatology‐associated clinics between 2000 and 2015. Patients were stratified according to their atopic dermatitis (AD) status. Results The study group included 3676 patients (median age 41 years, 34.8% males, 54.5% AD). The most common aeroallergens causing positive patch test reactions were Dermatophagoides pteronyssinus (19.6%), Dermatophagoides farinae (16.9%), birch (6.2%), timothy grass (6.0%), cat dander (5.4%), mugwort (4.9%) and dog dander (4.6%). Reactions to other pollen allergen preparations, that is 5 grasses (3.2%), cocksfoot (2.1%) and plantain (1.6%), were less common. Positive patch test reactions to aeroallergens were consistently more frequent in patients with AD. These patients showed proportionally less dubious, follicular, irritant and weak positive reactions. Independent of AD status, a patient history of past or present allergic rhinitis was associated with an increased chance of a positive aeroallergen patch test reaction to pollen allergens. Conclusion The aeroallergen patch test is a useful add‐on tool in clinical routine, especially in patients with AD and/or respiratory allergy. A patch test series comprising Dermatophagoides pteronyssinus, Dermatophagoides farinae, birch, timothy grass, cat dander and mugwort seems to be suitable. Controlled studies with specific provocation and elimination procedures are required to further evaluate the diagnostic significance of the proposed screening series.
