OBJECTIVES To contrast the initial suspected etiology of anaphylaxis with the postworkup diagnosis in patients attended at the emergency department (ED) of a tertiary-level hospital in Spain and to investigate the incidence, causes, and management of anaphylaxis. METHODS We performed an observational study of patients aged more than 15 years who came to the ED with anaphylaxis between 2009 an...

BACKGROUND There are no data on the percentage of visits due to anaphylaxis in the emergency department (ED), triggers, and management of anaphylaxis across different provinces in Canada. OBJECTIVE To compare the percentage of anaphylaxis cases among all ED visits, as well as the triggers and management of anaphylaxis between two Canadian pediatric EDs (PEDs). METHODS As part of the Cross-C...

BACKGROUND Pediatric anaphylaxis is commonly misdiagnosed in the Emergency Department (ED). We aimed to determine the impact of inaccurate diagnosis on the management and follow-up of pediatric anaphylaxis presenting to the ED. METHODS Retrospective chart review of ED management of children aged 0-18 years with allergic presentations to three EDs in Melbourne, Australia in 2014. Cases were in...

AIM To determine the frequency of anaphylaxis in an allergy outpatient department, allowing a better understanding regarding aetiology, clinical manifestations and management, in children and adolescents. METHODS From among 3646 patients up to 18 years old observed during one-year period, we included those with history of anaphylaxis reported by allergists. RESULTS Sixty-four children had h...

We report a rare case of anaphylaxis due to caffeine intake. A 27-year-old woman suffered her first episode of anaphylaxis and a positive skin prick test suggested that the anaphylaxis was due to an IgE-mediated hypersensitivity reaction to caffeine. She was diagnosed with caffeine allergy and has not had an allergic reaction after avoiding foods and drinks containing caffeine. Although caffein...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014208980 DESCRIPTION Food is the most common cause of anaphylaxis. Very few cases of mustard seed-induced anaphylaxis have been reported. We present a case of mustard seed anaphylaxis. A 29-year-old man presented to our department for evaluation of anaphylax...

BACKGROUND Cardiac anaphylaxis is accompanied by coronary spasm and decreased left ventricular (LV) contractility. However, it has not been determined experimentally whether LV dysfunction during anaphylaxis is induced mainly by reduced coronary blood flow (CBF) or direct negative inotropic actions of chemical mediators. To demonstrate the major role of CBF reduction in anaphylactic LV dysfunct...

Anaphylaxis is a life-threatening emergency that may be confused with other less serious conditions. The onset of true anaphylaxis typically occurs within minutes following exposure to an offending agent, and it can variably include dyspnea/wheezing, hemodynamic compromise, rash, hives/pruritus, swelling, or gastrointestinal symptoms. absence expected association between exposure(s) classic sym...


 Background: Anaphylaxis is an acutely presenting life-threatening medical emergency. Studies have shown that dentists feel inadequately able to recognize and treat anaphylaxis. This study aims determine the level of knowledge local anesthetic (LA) anaphylaxis among in a Nigerian Teaching Hospital.
 Methods: cross-sectional, questionnaire-based was conducted dental practitioners at D...

Background Anaphylaxis is a potentially life threatening allergic reaction. Failure to identify the inciting allergen places patients at risk of future life-threatening allergen exposure. Anaphylaxis guidelines recommend that all patients who experience anaphylaxis from an allergen encountered in a non-medical setting carry self injectable epinephrine and follow up with an allergist. Very littl...
