BACKGROUND
Allergic contact dermatitis (ACD) increases with age, and a prevalence of between 13.3% and 24.5% has been reported. Patch testing infants may be particularly difficult, and false-positive reactions may occur.
OBJECTIVE
The purpose of this retrospective study was to determine whether the
In this retrospective study, patch test results of 542 patients (303 female and 239 male), referred to our clinic between June 1996 and July 1999, were evaluated. All patients were patch tested with 32 allergens of an extended European standard series, 140 patients were tested with supplemental
BACKGROUND
Patients with lower leg dermatitis, chronic venous insufficiency or chronic leg ulcers have a high prevalence of contact sensitization.
OBJECTIVE
To identify the current spectrum of contact allergens in these patients.
METHODS
Data of the Information Network of Departments of Dermatology
Systemic manifestations of allergic contact dermatitis due to consumption of foods containing balsam of Peru (Myroxylon pereirae)-associated chemicals have recently been reported in children. We present seven children with widespread, recalcitrant dermatitis who experienced 60-80% clearance after
BACKGROUND
A 40 year old woman presented with dermatitis mainly involving her dorsal feet and shins, a condition which was present for a prolonged period of time. The distribution was suggestive of allergic contact dermatitis, possibly to her shoes. Patch tests disclosed allergy to chromates,
Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction. During the last decade, there has been a heightened awareness of this disease in the pediatric population. The gold standard for diagnosis is patch testing. The prevalence of positive patch tests in referred children
Allergic contact dermatitis is an uncommon but important cause of skin disease in the anogenital region. Relevant allergens are described in women and less commonly in men. The aim of this study was to describe outcomes of patch testing in men and women presenting with anogenital BACKGROUND
Contact allergy to phenol-formaldehyde resins (PFRs) based on phenol and formaldehyde is not detected by a p-tertiary-butylphenol-formaldehyde resin included in most baseline patch test series.
OBJECTIVE
The aims of this study were to investigate the contact allergy rate to PFR-2 in an
Balsam of Peru (PB; Myroxylon pereirae) is a natural product derived from resin of a tropical tree (MyroxyIon balsamum (L.) Harms var. pereirae (Royle) Baillon). Because of its antiseptic and aromatic properties PB or PB-components can be found worldwide not only in many health care and cosmetic
Allergic contact dermatitis (ACD) is an increasingly common diagnosis in children. The objectives of this study were to review our experience with ACD in children in tertiary settings, to ascertain the spectrum of allergens in this population and to subsequently propose the first OBJECTIVE
Patch testing is a standard diagnostic tool used in the identification of causative allergens in allergic contact dermatitis. Ongoing surveillance of rates of allergen positivity is vitally important to detect trends and allow comparisons between countries. The objective of this study was
Limonene, one of the most often used fragrance terpenes in any kind of scented products, is prone to air-oxidation. The oxidation products formed have a considerable sensitizing potential. In previous patch test studies on consecutively tested dermatitis patients, oxidized R-limonene has been proven
The tomato plant (Solanum lycopersicum) is an important crop worldwide. Whereas immediate-type reactions to tomato fruits are well known, contact dermatitis caused by tomatoes or tomato plants is rarely reported. The aims of this study were to present new data on contact sensitization to tomato
Patch testing is the criterion standard for diagnosis of allergic contact dermatitis (ACD).The aim of the study was to report the trends of patch testing results with the standard series at Massachusetts General Hospital from January 1, 2007, to December Contact eczema (CE) is one of the most common skin diseases and is regarded as a reaction pattern. However, the skin can react in the same way to different stimuli, some of which may act together. The golden standard in the diagnosis of allergic contact dermatitis (ACD) is the patch test. Contact
