BACKGROUND: Whether children with atopic dermatitis have an altered risk of contact allergy than children without atopic dermatitis is frequently debated and studies have been conflicting. Theoretically, the impaired skin barrier in AD facilitates the penetration of potential allergens and several authors have highlighted the risk of underestimating and overlooking contact allergy in children with atopic dermatitis. OBJECTIVE: To determine the prevalence of contact allergy in Danish children with atopic dermatitis and explore the problem of unacknowledged allergies maintaining or aggravating the skin symptoms...

Contact allergies are common cause of eczema in all age groups and are one of the most common causes of occupational disability. Contact dermatitis can be divided into irritant and allergic contact dermatitis. Distinguishing between irritant and allergic triggers of contact dermatitis by clinical and histologic examinations can be challenging. The approach to patients with contact dermatitis should consist of a detailed (work and leisure) history, skin examination, patch tests with allergens based on history, physical examination, education on materials that contain the allergen and adequate therapy and prevention...

INTRODUCTION: Tattooing has become a popular practice in western countries, particularly among younger populations. Tattoos, however, can cause complications, such as infections, allergic or foreign-body reactions, and even systemic inflammatory responses. PATIENTS AND METHODS: We conducted a retrospective study of all patients seen for tattoo-related complications at our skin allergy unit between January 2002 and December 2016. RESULTS: We studied 23 patients...

Esen Özkaya, Sıla Kılıç
BACKGROUND: Polyethylene glycols (PEGs) and propylene glycol (PG) are used as vehicles in various medicinal and cosmetic products. They are potential contact sensitizers, including low molecular weight PEGs in nitrofurazone preparations that are still widely used in Turkey. OBJECTIVES: To investigate the prevalence of allergic contact dermatitis caused by PEG and PG in a relatively large group of patients in Turkey. METHODS: In this retrospective, cross-sectional, single-centre study, 836 patients patch tested with PEG and PG between 1996 and 2015 were reviewed...

The main allergen responsible for contact dermatitis to nail polish is tosylamide-formaldehyde resin. The so-called hypoallergenic nail polishes are suposedly free of agents that commonly trigger reactions. The commercially available products and their compositions were studied. It was observed that most brands present at least one component capable of triggering the disease; therefore, allergic reaction may occur even when hypoallergenic polishes are used. There should be a proper investigation of the specific allergen through a patch test, because more than one component can cause an allergy, and we need to check the exact composition of each product...

BACKGROUND: The use of metal-containing bio-devices is becoming increasingly common. Self-reported history of dermatitis with metal exposure is not established as being predictive for metal allergy. OBJECTIVES: To assess the validity of two screening questions addressing metal allergy. METHODS: At Massachusetts General Hospital Contact Dermatitis Clinic, 2132 consecutive patients were asked either 'Do you get rashes when jewellery touches your skin' (Q1; N = 1816) or 'Do you get rashes when metal touches your skin?' (Q2; N = 316) before being patch tested...

Evy Paulsen, Klaus E Andersen
BACKGROUND: Compositae dermatitis was originally described as airborne contact dermatitis. More recent studies have reported a wider clinical spectrum, but often in polysensitized patients. OBJECTIVE: To evaluate the clinical features of patients sensitized to Compositae only. PATIENTS/METHODS: Consecutive Compositae-sensitive eczema patients, tested between 1990 and 2015, who, at the patch testing session diagnosing their Compositae allergy, were found to be sensitized only to the plant family, were included...

BACKGROUND: Calcipotriol, a synthetic vitamin D analogue, is widely used for the topical treatment of psoriasis. It often causes irritant reactions, whereas allergic contact dermatitis has less commonly been reported. OBJECTIVES: To report on 6 patients (among them an 11-year-old child) who presented with eczematous lesions complicating pre-existing dermatitis, observed in our tertiary referral patch test clinic between 2004 and 2016. METHODS: Patch tests were performed with the commercial preparation used by the patients and/or its ingredients, including calcipotriol (2 or 10 µg/ml in isopropyl alcohol), according to ESCD patch test guidelines...

Rachel K Severin, Donald V Belsito
BACKGROUND: Alkyl glucoside surfactants, present in many cosmetic products, can cause allergic contact dermatitis. Decyl glucoside has been part of the North American Contact Dermatitis Group standard allergen panel since 2009. OBJECTIVES: This study aimed to identify rates and relevance of positive patch test reactions to decyl and lauryl glucosides and to determine how well one of these glucosides screens for contact allergic reactions to the other. METHODS: A retrospective analysis was performed on 897 patients suspected of having a cosmetic-related dermatitis and patch tested with both decyl and lauryl glucosides between 2009 and 2016...

P Dickison, S D Smith
Allergic contact dermatitis (ACD) secondary to acrylates and methacrylates is a well- described occurrence, particularly in those who wear or handle gel nail varnish. Management involves avoidance of the identified allergen. The cause of chronic urticaria (CI) is often not identified, and CU is not known to be associated with acrylates or methacrylates. We report a case of a 50-year-old woman who initially presented with hand dermatitis exacerbated by gel nail varnish on a background of CU. Avoiding all nail varnishes because of her ACD also resulted in improvement of her CU...

Allergic contact dermatitis (ACD) is regarded as the most frequent expression of immunotoxicity in humans. Many odorant terpenes commonly used in fragrance compositions are considered as weak skin sensitizers, whereas some of their autoxidation products, allylic hydroperoxides, are classified as strong sensitizers according to the Local Lymph Node Assay (LLNA). However, the mechanism of their effects on the immune system remains unclear. Since dendritic cells play a key role in ACD, we studied their activation by the frequently used linalool (LINA) and limonene (LIMO), and their respective sensitizing allylic hydroperoxides (LINA-OOH, LIMO-OOH)...

S Baltà Cruz, N Moreno Ribera, M T Estrach Panella
INTRODUCTION: Although Mercromina Film and other topical antiseptics are widely used, they are not included in the standard series recommended by the Spanish Contact Dermatitis and Skin Allergy Research Group for testing suspected allergic contact dermatitis (ACD). Furthermore, no recent studies have investigated the allergenic potential of merbromin. OBJECTIVE: To determine the allergenic potential of merbromin and compare it with that of other topical antiseptics widely used in clinical practice, including povidone-iodine, chlorhexidine, and eosin...

The popularity of mobile wearable health devices has skyrocketed. Some of these devices are worn on the wrist and have been associated with the development of allergic contact dermatitis. Although nickel has been the suspected culprit in cases reported by the media for consumers, we present a rare report of a patient who developed a localized contact dermatitis that was linked to acrylate allergy on epicutaneous patch testing. We surmise that the source of this acrylate might derive from leaching of this compound from the rechargeable battery housing given its correspondence to where the rash arose...
