Article Synopsis
- Photoallergic contact dermatitis (PACD) is a hypersensitivity reaction triggered by allergens only when exposed to UV light, requiring photopatch testing (PhotoPT) for diagnosis.* -
- A study from 2009-2020 involving 454 patients revealed that most were women, aged 21-60, and the majority were White; results showed 119 positive tests, predominantly related to sunscreen agents like benzophenones.* -
- Among the diagnosed conditions, approximately 17.2% of patients had PACD, while other diagnoses included allergic contact dermatitis, polymorphous light eruption, and chronic actinic dermatitis, highlighting the need for photopatch testing in these cases.*
Introduction: Corticosteroids may cause delayed hypersensitivity. On the basis of structure, the following 4 groups of corticosteroids are recognized: A, B, C, and D (subdivided into D1 and D2). More recently, a newer classification system subdivides corticosteroids into groups 1, 2, and 3.

Methods: At 12 centers in North America, patients were tested in a standardized manner with a series of 70 allergens.
Background: Allergic contact dermatitis is common in children. Epicutaneous patch testing is an important tool for identifying responsible allergens.
Objective: The objective of this study was to provide the patch test results from children (aged ≤18 years) examined by the North American Contact Dermatitis Group from 2005 to 2012.
Background: Mercaptobenzothiazole (MBT) and mercapto compounds are primarily used in rubber products.
Objective: This study aimed to examine concomitant-positive rates of MBT (1% pet) and the 4-part mercapto mix (MM) (1% pet).
Design: This is a retrospective cross-sectional data from the North American Contact Dermatitis Group.
Topically applied cosmetics and medicaments containing botanical extracts are commonly used. Despite popular beliefs of their benignancy, some botanicals have been implicated in causing allergic contact dermatitis in susceptible patients. The offending allergen may be the botanical extract itself or another ingredient such as a fragrance, preservative, dye, or sunscreen found in the product.

Iodopropynyl butylcarbamate (IPBC) is a preservative used in industrial and personal care products. Potential cross-reactivity between these allergens is unclear.
View Article and Find Full Text PDFBackground: Both active and inactive ingredients in sunscreen may cause contact dermatitis.
Objectives: This study aimed to describe allergens associated with a sunscreen source.
Methods: A cross-sectional analysis of patients patch tested by the North American Contact Dermatitis Group between 2001 and 2010 was performed.
Background: Persistent photosensitivity after allergic contact dermatitis (ACD) to epoxy resin has rarely been described.
Objective: The aim of this study was to create awareness that ACD to epoxy may be a trigger for persistent photosensitivity.
Methods: We present a series of 5 patients who developed ACD to epoxy resin and later a photodistributed eczematous eruption when exposed to sunlight, with a documented decrease in minimal erythema dose to UVA and UVB.
Background: Patch testing is an important diagnostic tool for determination of substances responsible for allergic contact dermatitis.
Objective: This study reports the North American Contact Dermatitis Group (NACDG) patch testing results from January 1, 2009, to December 31, 2010.
Methods: At 12 centers in North America, patients were tested in a standardized manner with a screening series of 70 allergens.
Background: The American Contact Dermatitis Society (ACDS) is the principal organization representing the subspecialty of contact dermatitis in the United States.
Objective: The aim of this study was to characterize ACDS members with respect to demographic characteristics, patch-test practices, and sentiments regarding the Society and its journal Dermatitis.
Methods: We conducted cross-sectional postal and online surveys of ACDS members.
Background: Contact dermatoses are common in food service workers (FSWs).
Objectives: This study aims to (1) determine the prevalence of occupationally related contact dermatitis among FSWs patch tested by the North American Contact Dermatitis Group (NACDG) and (2) characterize responsible allergens and irritants as well as sources.
Methods: Cross-sectional analysis of patients patch tested by the NACDG, 1994 to 2010, was conducted.
Background: The North American Contact Dermatitis Group (NACDG) tests patients with suspected allergic contact dermatitis to a broad series of screening allergens and publishes periodic reports.
Objective: The aims of this study were to report the NACDG patch-testing results from January 1, 2007, to December 31, 2008, and to compare results to pooled test data from the previous 2 and 10 years to analyze trends in allergen sensitivity.
Methods And Materials: Standardized patch testing with 65 allergens was used at 13 centers in North America.
Background: European studies document that occupational contact dermatitis (CD) is common in hairdressers, but studies from North America are lacking.
Objectives: The objectives of this study were to estimate the prevalence of occupational CD among North American hairdressers/cosmetologists (HD/CS) and to characterize responsible allergens and irritants as well as their sources.
Methods: A cross-sectional analysis of patients patch tested by the North American Contact Dermatitis Group between 1994 and 2010 was conducted.
Background: Relatively little is known about the epidemiology of allergic contact dermatitis in older individuals.
Objectives: We sought to determine the frequency of positive and clinically relevant patch test reactions in older individuals (≥ 65 years old) referred for patch testing, and to compare these results with those of adults (≤ 64-19 years) and children (<18 years).
Design: This was a retrospective cross-sectional analysis of North American Contact Dermatitis Group data from 1994 to 2008.
Background: iodopropynyl butylcarbamate (IPBC), a commonly used preservative, is found in industrial and personal care products.
Objective: to evaluate prevalence, clinical relevance, occupational relationship, and sources of positive reactions to IPBC in patients in North America.
Methods: the North American Contact Dermatitis Group (NACDG) tested IPBC 0.
Allergic contact dermatitis due to citrus fruits is rare, but has been reported in cooks and bartenders. We report an interesting case of a bartender with hand dermatitis who had an allergic contact sensitivity to lime peel, fragrance mix I, and fragrance mix II. Most reported cases of citrus peel allergy are due to d-limonene, which makes up the majority of the peel oil.
View Article and Find Full Text PDFBackground: Rising use of sunscreen products has led to increased reporting of adverse reactions to sunscreens.
Objective: To investigate possible photoallergic reactions in patients who identified themselves as "being allergic" to sunscreens.
Methods: Patients filled out questionnaires about types of sunscreens they used and timing of their "allergic" reactions.
Background: The positivity ratio (PR) and reaction index (RI) characterize the ability of patch-test preparations to produce strong (++ or +++) reactions as opposed to weak (+), questionable, or irritant reactions.
Objective: This study evaluates these measures for North American Contact Dermatitis Group (NACDG) patch-test preparations.
Methods: The PR and RI were calculated for 79 NACDG standard allergens tested from 1994 to 2006 (n = 26,479 patients).
Background: Identification of putative contact allergen and source material is often done by a combination of patch testing and manufacturer-supplied product information. The accuracy of the identification of allergen-source material and level of allergen in that allergen-source material is not known.
Objective: The objectives of the study were to survey the chemical allergen content of glove allergic contact dermatitis (ACD) patient-identified problem and nonproblem gloves and to evaluate the ability of the patient to discriminate between problem and nonproblem gloves.
