AI Article Synopsis
- The study examines the effectiveness of a standardized allergy history questionnaire compared to the existing allergy history form at UHNBC, focusing on documenting patients' allergies.
- Results show that many patients had incorrect allergy labels in their EMR, with incomplete reactions recorded; 40% had inappropriate allergy labels.
- The findings suggest that using a standardized questionnaire could improve allergy documentation and support better antimicrobial stewardship.
Article Abstract
Background: Inappropriate allergy labelling is associated with significant clinical and pharmacoeconomic implications. Detailed antimicrobial allergy assessments represent a key component of antimicrobial stewardship and aid in identifying true type I (immediate hypersensitivity) reactions. The allergy history form currently used at the University Hospital of Northern British Columbia (UHNBC), in Prince George, relies on the assessor's ability to ask appropriate prompting questions to obtain a thorough history, but it may not be sufficient to accurately identify true allergies.
Objective: To compare a standardized allergy history questionnaire and the current allergy history form in terms of the quality and quantity of documentation gathered.
Methods: This prospective observational study involved patients who were admitted to medical and surgical services at UHNBC from November 2018 to January 2019 with a penicillin-class allergy reported on their electronic medical record (EMR). A list of patients with EMR-reported allergies was generated by the hospital's health information software system, and these patients were interviewed using the standardized allergy history questionnaire.
Results: A total of 48 patients were assessed during the study period. Nineteen (40%) of the patients had an inappropriate allergy label on their EMR. Only 36 (75%) had an allergic reaction described on their EMR. Furthermore, only 36 (75%) of the 48 patients had the same allergy recorded on the EMR and on the allergy history form contained in their paper chart, of whom 22 had a documented reaction. The mean time to complete the standardized allergy history questionnaire was 2 minutes.
Conclusions: At the study institution, documentation of allergy histories was often incomplete. Detailed allergy assessments are the first step in identifying true immunoglobulin E-mediated hypersensitivity reactions. Utilization of a standardized allergy history questionnaire is feasible and may serve to improve documentation and overall antimicrobial stewardship.

Diversity of complementary diet and early food allergy risk.
Pediatr Allergy Immunol
January 2025
Department of Clinical Sciences, Pediatrics, Umeå University, Umeå, Sweden.
Introduction: Diet diversity (DD) in infancy may be protective for early food allergy (FA) but there is limited knowledge about how DD incorporating consumption frequency influences FA risk.
Methods: Three measures of DD were investigated in 2060 infants at 6 and/or at 9 months of age within the NorthPop Birth Cohort Study: a weighted DD score based on intake frequency, the number of introduced foods, and the number of introduced allergenic foods. In multivariable logistic regression models based on directed acyclic graphs, associations to parentally reported physician-diagnosed FA at age 9 and 18 months were estimated, including sensitivity and stratified analyses.

Kounis syndrome also known as allergic myocardial infarction, represents the simultaneous occurrence of acute coronary syndromes with allergic or hypersensitivity reactions. We present a case of a 58-years-old male who developed anaphylaxis following a leech bite, leading to myocardial infarction despite the absence of prior allergic history. He was entubated and cardiopulmonary resusciation had been performed for 10 minutes.

Objective: Bacterial extracts have been used for many years to prevent airway infections. Recent findings suggest that immunity can be trained by inducing an immunological memory in both the innate and acquired immune response. This real-life observational study investigated the potential of sublingual bacterial immunotherapy in the prevention of ear, nose, and throat infections.

Background Interstitial lung diseases (ILDs) are a group of non-infectious diseases characterized by interstitial inflammation and fibrosis on histological examination. Gastroesophageal reflux disease (GERD) is common in this patient population, but whether there is a causal or coincidental relationship is not yet clear. It still remains unsettled how to diagnose GERD, and the role of different treatment modalities for GERD, in these lung disorders.
