A rare long-term side effect of COVID-19 vaccines: Symmetrical drug-related intertriginous and flexural exanthema-like reaction SDRIFE and potential immunogens for delayed type hypersensitivity reactions.

Background: Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is an important clinical entity that is rare and may develop with a Type IV delayed type hypersensitivity immune response to drug antigens. The incidence and characteristics of SDRIFE attributed to COronaVIrus Disease of 2019 (COVID-19) vaccines remain unclear, this issue requires further elucidation.

Objective: We aim to investigate the vaccine-related-SDRIFE and potential immunogens of COVID-19 vaccines through a literature review accompanied by a real case.

Early testing and grade of the reaction are affecting factors of skin test positivity in β-Lactam allergies.

β-Lactams are the most widely used antibiotic family in the world. Nevertheless, they also stand out as the primary culprits for inducing drug hypersensitivity reactions (HSR). Between May 2018 and March 2023, patients with suspected HSRs to β-lactams, who underwent skin tests (ST), were retrospectively screened.

In Vitro Effects of Boric Acid on Cell Cycle, Apoptosis, and miRNAs in Medullary Thyroid Cancer Cells.

Medullary thyroid cancer (MTC) is a highly aggressive and chemotherapy-resistant cancer originating from the thyroid's parafollicular C cells. Due to its resistance to conventional treatments, alternative therapies such as boric acid have been explored. Boric acid, a boron-based compound, has shown anticarcinogenic effects, positioning it as a potential treatment option for MTC.
