Summary
American Contact Dermatitis Society members utilize extensive patch testing allergen trays, with limited use of the T.R.U.E. Test. Regular use of the Contact Allergen Replacement Database (CARD) is recommended for diagnosing allergic contact dermatitis.
Area of Science:
- Dermatology
- Allergology
- Contact Dermatitis
Background:
- Patch testing is crucial for diagnosing allergic contact dermatitis.
- Significant variability exists in patch testing methodologies among practitioners.
Purpose of the Study:
- To survey American Contact Dermatitis Society (ACDS) members regarding time spent on contact dermatitis patients.
- To characterize patch testing practices, including the T.R.U.E. Test.
- To assess the utilization of the Contact Allergen Replacement Database (CARD).
Main Methods:
- An electronic survey was distributed to all ACDS members.
- 100 ACDS members participated, yielding a 16.6% response rate.
Main Results:
- Respondents' patch testing trays averaged 62 allergens.
- 68% used the North American Contact Dermatitis Group series; only 9% used the T.R.U.E. Test.
- The T.R.U.E. Test's limited allergen count was a primary criticism; 94% regularly used CARD.
Conclusions:
- ACDS members prefer comprehensive patch testing allergen trays over the T.R.U.E. Test.
- Routine utilization of CARD should be promoted for improved allergic contact dermatitis diagnosis.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
