BACKGROUND Hand eczema is not uncommon in children but it is rarely studied using skin-prick tests. Few reports have addressed their usefulness in children and none has specifically analyzed their use in children with hand eczema. MATERIAL AND METHODS We performed a retrospective study of all children up to 16years of age with hand eczema who were assessed in the Department of Dermatology at ...
Methylisothiazolinone (MI) (CAS no. 2682-20-4) and methylchloroisothiazolinone (MCI) (CAS no. 26172-55-4) have been widely used as preservatives in cosmetics, household products and industrial products since the late 1970s. The first cases of contact allergy to the MCI/MI combination were noted in 1980 (1). Ironing water is being increasing used as a product designed to making ironing more enjo...
Diethyl sebacate is used in topical medicaments in United States and Japan. We described a case of allergic contact dermatitis from diethyl sebacate in a topical antimycotic medicament. Allergic reaction to diethyl sebacate is likely more common because our group has found three of eight sensitized cases. We believe that an investigation regarding the sensitized frequency to diethyl sebacate wo...
Nickel allergic contact dermatitis (ACD) has become a more widely recognized disease process over the last three decades in the United States. A subpopulation of ACD patients will manifest with systemic contact dermatitis (SCD). Specifically, those cases of widespread recalcitrant nickel ACD with only partial clinical relief after strict nickel avoidance, suggest SCD. Evidence indicates that ap...
A 35-year-old male was referred because of eczema on the arms and lips that occurred episodically. He worked in a drug-manufacturing plant, and noticed that the episodes of eczema coincided with the production cycles of thebaine (CAS no. 115-37-7) and oripavine (CAS no. 467-04-9), but not with the production cycles of morphine (CAS no. 57-27-2) and noscapine (CAS no. 128-62-1). The eczema start...
INTRODUCTION Black-spot poison ivy is an uncommon clinical manifestation of contact with Toxicodendron plants. Unlike allergic contact dermatitis, which typically manifests in sensitized individuals within 2448 hours, the black lacquer that results from oxidation of the oleoresin after contact with the plant develops within hours of exposure and precedes allergic contact dermatitis, in some cas...
BACKGROUND Background: Patch tests are an efficient method to confirm the etiological diagnosis of allergic contact dermatitis. OBJECTIVES 1) To determine the permanence of results between two tests performed with an interval of at least one year, in patients with allergic contact dermatitis; 2) To compare the positive results according to rates of intensity; 3) To evaluate the permanence of ...
Epoxy resins, widely used as adhesives or coatings in construction, boat and aeroplane building, plastic and other industries and trades (1–3), are a frequent cause of occupational allergic contact dermatitis (1–6). Epoxy resin based on diglycidylether of bisphenol A is the main allergen responsible but sensitization can also develop to other components, including the hardeners and reactive dil...
BACKGROUND Cosmetic products contribute considerably to the incidence of contact dermatitis. In response to a resolution of the Council of Europe, the National Institute for Public Health and the Environment (RIVM) in The Netherlands set up a pilot project to report undesirable effects attributed to cosmetic products. OBJECTIVES To provide an overview of undesirable effects attributed to cosm...
Nail art (creation and decoration of artificial nails) is a growing fashion trend. Proportionally to its popularity, the number of allergic reactions to the materials used has recently increased. We report the case of a nail art operator who developed occupational allergy to acrylates, manifested with the unusual simultaneous presence of asthma and dermatitis. Cutaneous lesions only affected ar...
