A case of immediate‐type allergy from polypropylene in a particle filter mask in a nurse

Purpose of Review Contact urticaria syndrome includes contact urticaria and protein contact dermatitis. Underreport, underdiagnosis, or misdiagnosis of entities within the contact urticaria syndrome is believed to be common, especially in the occupational setting. This review provides a structured overview of the entities comprised in this syndrome as well as the diagnostic work-up and management strategies. Recent Findings Contact urticaria syndrome has been increasingly described due to personal protective equipment and hand sanitizers in the context of the COVID-19 pandemic. The use of legal cannabis products has led to a rise in occupational cases of contact urticaria to cannabis. A declining trend in the evolution of contact urticaria has been described for natural rubber latex allergy due to the use of synthetic gloves. Prick test has been proposed as a screening method, particularly if multiple products are to be tested, instead of the classical sequential scheme. Summary Physicians should be aware of the growing number of culprit agents leading to contact urticaria syndrome. Clinical presentation may be challenging since it includes immediate urticaria and/or eczema and even more generalized reactions. Diagnosis requires a high degree of suspicion, detailed occupational history, and complementary tests, including skin testing. The best treatment is to avoid contact with the culprit agent and to implement preventive measures.

Background Medical devices are not subject to any legal obligation to declare ingredients. With an increasing number of available medical devices, increasing reports of contact allergies to these devices result in a more difficult, delayed or lack of diagnosis of the trigger. Methods Elaborate chemical methods, such as gas chromatography–mass spectroscopy, were able to detect novel contact allergens in medical devices. Results Diabetic patients requiring insulin benefit from sophisticated glucose sensor measurement systems and insulin pump systems, but are limited in their choices by the development of contact allergy. Potential contact allergens in medical adhesives, plasters, and wound dressings require extensive diagnostic testing. Contact allergic reactions to cardiac electronic implants are rare. The potential relevance of a contact allergic reaction to endoluminal stents to restenosis of the treated vascular territory is discussed. Contact dermatitis to medical gloves is usually due to the vulcanization accelerators. Mouth–nose protective or FFP2 mask-associated eczema is often irritant, very rarely allergic in origin. Conclusion With continued development of medical devices, new contact allergens are introduced. The declaration of their ingredients is necessary for rapid diagnosis and future prevention.
