BACKGROUND Footwear dermatitis represents a common but often undiagnosed or misdiagnosed condition. Patch testing aids in its confirmation and identification of the offending allergen. AIMS This study aimed to find the frequency of positive patch test reactions in cases with suspected allergic contact dermatitis (ACD) to footwear, as well as the common responsible allergens. MATERIALS AND M...

Occupational and non-occupational contact allergy to, and allergic contact dermatitis caused by, acrylates/methacrylates are frequently reported (1–18). However, there is no acrylate/methacrylate test preparation in the European baseline patch test series (19). Therefore, contact allergy to, and allergic contact dermatitis caused by, acrylates/methacrylates may be overlooked when the decision i...

ibuprofen was positive in a residual lesion, while patch test with the same drug was negative in upper back. We were curious to know if our patient was sensitised to the rest of the propionic acid group, but due to the small area affected skin, we could not test these additional drugs. Therefore all propionic acid group drugs were forbidden. The patient tolerated acetylsalicylic acid, and then ...

INTRODUCTION Persistence of allergen and immunocompetent cells at sites of healed contact dermatitis has been reported. Flare-up reactions triggered by patch testing and after systemic provocation with allergen are well-known phenomena. To our knowledge, we report the first flare-up of a previous patch test site following casual cutaneous application of nickel in an individual with hitherto lat...

In evaluation of medication allergy, the utility of drug patch testing is dependent on both the type of drug reaction and the suspected causal drug. Epicutaneous patch tests reproduce T cell-mediated delayed hypersensitivity; thus, eruptions at least partially mediated by T cells can be confirmed by positive drug patch test (DPT) responses in some patients. These include acute generalized exant...

High-impedance, sharp intracellular electrodes were compared with whole cell patch electrodes by recording from single spinal neurons in immobilized frog tadpoles. A range of neuron properties were examined using sharp or patch test electrodes while making simultaneous recordings with a second control patch electrode. Overall, test patch electrodes did not significantly alter the activity recor...

The term compound allergy is used to describe a condition in patients who are patch test-positive to formulated products, but are patch test-negative to all the ingredients when these are tested individually. We report 8 cases of contact dermatitis to VEA® lipogel (Ulka, Rovigo, Italy), a cosmetic that has previously been reported as the cause of compound allergy (1). All cases were observed at...

Software patches are often poorly tested, with many of them containing faults that affect the correct operation of the software. In this paper, we propose an automatic technique based on symbolic execution, that aims to increase the quality of patches by providing developers with an automated mechanism for generating a set of comprehensive test cases covering all or most of the statements in a ...

Correspondence To the Editor: A 65‑year‑old woman was admitted to Peking Union Medical College Hospital because of rash with pruritus for 1 month after taking Euthyrox. Rash attacked without other symptoms 20 days after she took Euthyrox 50 μg once a day and aggravated when Euthyrox was continued for the next 2 days. The past history included partial thyroidectomy for hyperthyroidism in 1982; t...
