Patent Blue V (PBV) is extensively used in sentinel lymph node identification in cancer surgery, potentially leading to an increased incidence of hypersensitivity reactions. A retrospective analysis was conducted on patients with suspected PBV hypersensitivity, at our center from 2010 to 2023. Skin prick tests (SPT) were performed on all patients, followed by intradermal tests (IDT) if SPT was negative.

Background: Food allergy has been shown to negatively impact children's mental health and quality of life. However, its impact on school performance is unknown.
Objective: We aimed to investigate whether food allergy, severe and nonsevere, is associated with school performance when accounting for measured and unmeasured familial factors.

Background: Cefazolin is the most common first-line antibiotic to prevent surgical-site infections. Patients with penicillin allergy labels often receive alternative antibiotics, which is associated with increased rates of surgical-site infections, multi-drug-resistant infections, and cost.
Objective: We sought to determine whether a hospital-wide guideline recommending first-line surgical prophylaxis in patients with penicillin allergy labels can increase the use of cefazolin without compromising safety.

Background: Chlorhexidine gluconate (CHX), a common cause of perioperative anaphylaxis, is frequently used for skin testing in allergy evaluations. Although CHX's maximal nonirritating concentrations are known, the stability of its dilutions for skin testing remains unexplored, particularly when sterile water for injection (SWFI) or normal saline (NS) are used as diluents.
Objective: Our aim was to evaluate the stability and precipitation of CHX when diluted with SWFI or NS for drug allergy skin testing.

Neuromuscular blocking agents are a common cause of perioperative hypersensitivity. The sensitivity and specificity of skin tests and in vitro tests in this context have not been determined conclusively, which poses a barrier to accurate diagnosis. Use of challenge testing represents a promising development in this field and a key tool in confirming tolerance to an alternate neuromuscular blocking agent for use in future anaesthesia.
