Hypersensitivity Reactions

The goal of this clinical trial is to investigate biomarkers of non-IgE-mediated immediate hypersensitivity reactions during infusion of intravenous vancomycin. The main question it aims to answer is: • Identifying novel biomarkers in blood that occur during infusion reaction Participants will: * Have allergy skin testing for vancomycin * Receive an infusion of vancomycin

The purpose of this study is to document the incidence of allergic contact dermatitis (ACD) to silk fibroin and 2-octyl cyanoacrylate mesh dressings after open shoulder surgery, to identify differences in clinic utilization for complications related to silk fibroin and 2-octyl cyanoacrylate mesh dressings and to collect patient reported outcome measures (PROMs) related to patient comfort and satisfaction for silk fibroin and 2-octyl cyanoacrylate mesh dressings.

This study is a prospective, multi-center, observational post-market safety study evaluating the incidence of anaphylaxis and hypersensitivity reactions associated with LUMISIGHT (pegulicianine) administration in adults with breast cancer undergoing lumpectomy surgery. Participants are indicated to receive LUMISIGHT as part of their breast cancer care. There is no investigational drug associated with this study. LUMISIGHT has a risk of serious hypersensitivity reaction, and this study seeks to further evaluate that risk.
