AI Article Synopsis
Article Abstract
The strip patch test is recommended whenever a patch test is presumed to be false negative. The aim of this technique is to increase skin sensitivity to test substances by removing the upper layers of the stratum corneum prior to patch testing. We report on a 57-year-old former heavy-current electrical worker, who suffered from hyperkeratotic fissured hand eczema. Sensitization to nickel sulphate was demonstrated in both 2001 and 2009 with strip patch testing even though conventional patch testing was negative. To our knowledge, this is the first description of an allergy to nickel with a pension entitlement according to no. 5101 of the German ordinance on industrial disease based solely on positive strip patch tests.

Chronic wound management requires continuous monitoring to assess healing and guide treatment. We developed a hollow microneedle array patch integrated with a lateral flow immunoassay strip to address the need for convenient, home-based diagnostics. This device extracts wound exudate directly from the wound matrix, overcoming the limitations of conventional swab sampling, which relies on surface exudate collection.

Purpose: To assess the variability in graft biomechanical properties of an acellular human dermal matrix patch.
Methods: A total of 22 strips obtained from 6 separate graft specimens (AlloPatch HD) were tested. Load elongation properties after cyclic loading, including ultimate load at break, energy at break, and extension at break, were tested and compared by graft thickness.

Rapid diagnostic tests (RDTs) offer valuable diagnostic information in a quick, easy-to-use and low-cost format. While RDTs are one of the most commonly used tools for in vitro diagnostic testing, they require the collection of a blood sample, which is painful, poses risks of infection and can lead to complications. We introduce a blood-free point-of-care diagnostic test for the rapid detection of protein biomarkers in dermal interstitial fluid (ISF).
