Purpose: To describe a case of anaphylactic reaction during implantation of the Ovation Abdominal Stent Graft System in a patient treated for abdominal aortic aneurysm (AAA).
Case Report: An 82-year-old man with a 5.3-cm asymptomatic AAA underwent endovascular repair using an Ovation stent-graft. Polymer was infused into the inflatable rings of the aortic body under continuous angioscopy, but the rings were not filled, even though the entire amount of the polymer was administered. Simultaneously, the patient presented with a severe anaphylactic reaction resulting in cardiopulmonary arrest. He was successfully resuscitated, but the procedure was abandoned; the patient refused any further treatment.
Conclusion: A rupture of the Ovation main body's polymer-filled rings may lead to extremely severe anaphylactic reaction.

Objective: Patients with uncontrolled gout have few treatment options. Pegloticase lowers serum urate (SU) levels, but antidrug antibodies limit SU-lowering response and increase infusion reaction (IR) risk. Methotrexate (MTX) cotherapy increases pegloticase response rates and lowers IR risk in pegloticase-naïve patients.

Rationale: Approximately 32 million people in the United States suffer from food allergies. Some food groups, such as legumes - peanuts, tree nuts, fish, and shellfish, have a high risk of cross-reactivity. However, the murine model of multiple food group cross-reactivity is limited.

Introduction: COVID-19 vaccination has been a key intervention in reducing the severity of symptoms; however, concerns about vaccine safety, particularly regarding allergic reactions, arose early on. Healthcare workers faced the challenge of addressing these concerns to ensure safe vaccine administration. This study aimed to review the practical aspects of using allergy skin testing for COVID-19 vaccine excipients in patients with a history of allergic reactions developed following mRNA COVID-19 vaccination.

Background: Adverse effects following immunizations (AEFIs) can contribute to vaccine hesitancy.
Objective: We evaluated clinical outcomes of AEFIs subsequent to administration of the coronavirus disease 2019 (COVID-19) vaccine at 2 pediatric allergy centers.
Methods: Data on pediatric patients referred for COVID-19 AEFI concerns between March 2021 and October 2022 were reviewed.
