Filter by:The interest of health databases in anesthesia is no longer to be demonstrated. The aim of this research was to develop a natural language processing approach to establish a classification of adverse events observed during the perioperative period and to facilitate their analysis: The main objective of the study was to identify what a "naïve" unsupervised model would discover based on Adverse Event (AE) descriptions. Our second goal was to identify apparently unrelated events whose combination could favor the occurrence of an AE
IgE-mediated food allergy can manifest with reactions ranging from hives to anaphylactic shock. The diagnosis is based on the confirmation of sensitization to the food allergen by skin tests (prick) and the determination of specific IgE directed against the food source and molecular allergens. The gold standard remains the oral provocation test, which is performed in a hospital environment. Once the diagnosis is made, an elimination diet is still considered as the cornerstone of treatment for most food allergies. While some allergies, such as cow's milk or egg, tend to resolve spontaneously, others, such as allergy to pecan nuts, show a tendency to be persistent. In addition, pecan allergy is often characterized by potentially serious clinical reactions, compared to other foods, which can even be life threatening. In our clinical practice, the investigators found that patients with allergies to pecan nuts often present with severe hypersensitivity reactions when challenged orally to this food. Beyond this information, there are few studies regarding pecans. The investigators decided to retrospectively evaluate the results of oral food challenge and of the allergy work-up in our patients sensitized and allergic to pecan nuts, to better understand the current epidemiology of such food allergy.
Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: - To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a High-Allergy/Mast Cell Disorder (HA/MCD) population, and - If the risk in the HA/MCD is demonstrable, to determine whether the proportions are higher in the HA/MCD in comparison to a representative population without severe allergies or mast cell disorders
Single-center, monadic, one day study utilizing the skin prick method to assess the allergy potential of Omeza Collagen Matrix in Human Subjects
The purpose of this study is to compare clinical outcomes of patients with self reported nickel sensitivity undergoing primary total knee arthroplasty (TKA) with conventional, standard-of-care vs nickel-free implants. The hypothesis is that patients with a self-reported nickel sensitivity will have similar patient reported outcome scores compared to those patients without reported nickel sensitivity. Therefor the anticipation is for there to be no differences in other clinical outcome measures or functional outcome scores between the two cohorts.
Anaphylaxis is an allergic reaction potentially fatal. The treatment is based on injection of epinephrin as soon as possible. Guidelines by the World Allergic Organisation highlight the importance of medical follow-up. This follow-up consists of an allergy consultation, the prescription and demonstration of epinephrin auto-injector and the implementation of specific measures in schools. There is no study about the recurrence of anaphylactic reaction outside the hospital. The purpose of this study is to evaluate the allergy follow-up of children after anaphylactic reaction. The secondary objective is to evaluate the use of medical advice in case of recurrence of anaphylactic reaction. Investigators will use a phone call questionnaire for parents of children who underwent an anaphylactic reaction between the 1st July 2014 and the 31st June 2016 treated in the Paediatric Emergency Department in Femme-Mère-Enfant Hospital in Lyon in France. 179 children could be included in the study.
Iodinated contrast agents (ICA) are widely used in medical imaging. They provide however a risk of immediate hypersensitivity reactions (IHS). The risk of anaphylactic shock is estimated at 1/100 000 injections. Nevertheless, for safety reasons and to limit undesirable effects, the reintroduction tests are not conducted along similar lines to throughout scan or arteriography. Moreover, reintroduction protocols are actually not standardized, in terms of injected volume and doses progression. It should be evaluated the relevance of the reintroduction tests with injection of a low volume and ensure the absence of reaction during the ICA injections Under real conditions. The investigators are assuming that the realization of a provocation test by intravenous reintroduction with a reduced dose of ICA improves the predictive value of IHS in comparison with only cutaneous tests.
This study will examine the within-tester repeatability and between-tester reproducibility of skin test endpoint titrations performed in those with allergic sensitivities.
Local allergic rhinitis (LAR) is relatively new disease. The question of effect of allergen specific immunotherapy on LAR is open. The randomized, double blind placebo controlled trial of birch subcutaneous AIT on LAR were performed in twenty eight patients. The therapy was performed during 24 months in proportion 15 patients with AIT and 13 placebo. The primary endpoint was decreased of symptoms medication score (SMS). Additionally monitoring serum specific IgE, specific IgG4 and nasal specific IgE (nsIgE) to Bet v1 and parameters of safety and quality of life were provided.
The main objective of this study is to validate the utility of IgE anti-cetuximab in the treatment strategy to identify patients at risk for a severe allergic reaction to cetuximab (grade 3 or 4 of the classification of NCI) and thus reduce the incidence of severe reactions.
