Allergic contact dermatitis (ACD) may complicate the clinical course of atopic dermatitis (AD), and patch testing remains the criterion standard for diagnosing ACD. To date, there have been no guidelines or consensus recommendations on when and how to patch test individuals with AD. Failure to patch test when appropriate may result in overlooking an important and potentially curable complicatin...

Patch testing is essential for identification of culprit allergens responsible for allergic contact dermatitis. This manuscript reviews how to perform patch testing and how to read and interpret the results.

Local anesthetics are widely used in clinical practice, and adverse effects are not uncommon. Delayed hypersensitivity reactions are among the most common effects, but immediate-type reactions may also occur. Patch testing should be considered in patients with hypersensitivity reactions. We present a case of allergic contact dermatitis to benzocaine that was detected incidentally by patch testi...

BACKGROUND The widespread use of fragrance-containing products is probably the most important reason for its high impact in allergic contact dermatitis. OBJECTIVES To describe the frequency of contact allergy to fragrance allergens as tested in the standard series, in relation to age, sex and lesion locations. To determine trends in frequency over the years and to study the association betwee...

Contact allergy to and allergic contact dermatitis from methyldibromo glutaronitrile (MDBGN) have frequently been reported. This study was initiated to help determine the optimal patch test preparation for MDBGN. In 51 patients with a doubtful or a positive patch test reaction to at least 1 of 4 test preparations with MDBGN in petrolatum at 1.0% w/w, 0.5%, 0.3% and 0.1%, a repeated open applica...

This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several ...

BACKGROUND Currently, cosmetic series (Chemotechnique Diagnostics, Sweden) is the most widely used cosmetic-related patch test in Korea. However, no studies have been conducted on how accurately it reflects the constituents of the cosmetics in Korea. OBJECTIVE We surveyed the constituents of various cosmetics and compare with the cosmetic series, to investigate whether it is accurate in deter...

The classical shimmying wheel is the simplest mechanical model to describe vibration problems in the rolling dynamics of aircraft nose gears, motorcycles , automotive systems and tractor-trailer systems. Such systems can exhibit undesirable unstable rolling motion which can often lead to disastrous results. The classical shimmy model includes a rigid wheel towed by a horizontal caster attached ...

68 Irritant contact dermatitis (ICD) is a common skin condition and a risk factor for allergic contact dermatitis. The prevalence of this disease in the general population varies between 1.7% and 6.3% and is increasing. The role of the patch test in detection of contact sensitivity is of prime importance. Patch tests should be used to identify topical agents that may be responsible for exacerba...

This paper describes the development and significance of online systems for the collection and analysis of medical data (patch test results) with a web application. Modern digital tools greatly aid in collecting, combining, and preserving the data in a way that is friendly, undemanding and time-efficient for the dermatologist. Creating a central database for the results of patch testing provide...
