Safety in dermatologic procedures: anaphylaxis, vasovagal reaction, and hyperventilation.

Actas Dermosifiliogr 2021 Jun 18. Epub 2021 Jun 18.

Servicio de Dermatología, Complejo Asistencial de Zamora, Zamora, Spain.

This article, part of a the series on safety in dermatologic procedures, covers the diagnosis, prevention, management, and treatment of 3 situations or conditions. The first condition we address is anaphylaxis, an uncommon but severe and potentially fatal reaction that must be recognized quickly so that urgent management coordinated with an anesthesiologist can commence. The second is fainting due to a vasovagal reaction, which is the most common complication in dermatologic surgery. Read More

The Revenge of Unintended Consequences of Anaphylaxis-Risk Overdiagnosis: How Far We've Come and How Far We Have to Go.

J Allergy Clin Immunol Pract 2021 Jun 17. Epub 2021 Jun 17.

Dartmouth-Hitchcok Medical Center, Section of Allergy and Immunology, Lebanon, NH; Geisel School of Medicine at Dartmouth, Hanover, NH. Electronic address:

Overdiagnosis of anaphylaxis-risk is an underappreciated aspect of anaphylaxis prevention. While the benefits of anaphylaxis-risk prevention are well-known, potential harms resulting from pre-emptive approaches to mitigate anaphylaxis-risk are not insignificant. Still, great progress has been made in recent years to avoid the unintended consequences of anaphylaxis-risk overdiagnosis. Read More

Clin Exp Allergy 2021 Jun 18. Epub 2021 Jun 18.

School of Psychology, Faculty of Health & Medical Sciences, University of Surrey, Guildford, United Kingdom.

Food allergy (FA) is a source of anxiety which affects the quality of life (QoL) of individuals and their caregivers (1). Furthermore, parental anxiety is a risk factor for anxiety development in children with offspring of anxious parents being seven times more likely to meet the criteria for an anxiety disorder (2). Recommendations have been made to address parental anxiety and its associated restrictive behaviours specifically for children with FA (3). Read More

Memory Generation and Re-Activation in Food Allergy.

Immunotargets Ther 2021 9;10:171-184. Epub 2021 Jun 9.

McMaster Immunology Research Centre, Department of Medicine, Faculty of Health Sciences, McMaster University, Hamilton, Ontario, Canada.

Recent evidence has highlighted the critical role of memory cells in maintaining lifelong food allergies, thereby identifying these cells as therapeutic targets. IgG memory B cells replenish pools of IgE-secreting cells upon allergen exposure, which contract thereafter due to the short lifespan of tightly regulated IgE-expressing cells. Advances in the detection and highly dimensional analysis of allergen-specific B and T cells from allergic patients have provided insight on their phenotype and function. Read More

MiR-154-5p-MCP1 Axis Regulates Allergic Inflammation by Mediating Cellular Interactions.

Front Immunol 2021 31;12:663726. Epub 2021 May 31.

Department of Biochemistry, Kangwon National University, Chuncheon, South Korea.

In a previous study, we have demonstrated that p62, a selective receptor of autophagy, can regulate allergic inflammation. In the present study, microRNA array analysis showed that miR-154-5p was increased by antigen (DNP-HSA) in a p62-dependent manner in rat basophilic leukemia cells (RBL2H3). NF-kB directly increased the expression of miR-154-5p. Read More
