Risk of peanut- and tree-nut-induced anaphylaxis during Halloween, Easter and other cultural holidays in Canadian children

The risk of anaphylaxis on holidays

PURPOSE OF REVIEW

The goal of this review is to summarize the potential causes of anaphylaxis in the different holiday contexts, providing practical suggestions aimed to mitigate the stress challenged by allergic patients because of unfamiliar situations.

RECENT FINDINGS

A regard was reserved to potential food triggers, particularly uncommon ones and typical of certain destinations, and to arthropods responsible for anaphylaxis.

SUMMARY

This review highlights the potential risk of anaphylaxis due to the unusual contexts more experienced during holidays (i.e., travels, outdoor activities and eating out). Moreover, it underlines the need for a further allergological education in these cases, in order to prepare allergic patients to avoid and manage undesired situations.

Plastic and Reconstructive Surgery in the Wake of the Eid al-Adha: A Single-Center, Five-Year Investigation

(1) Background: The Festival of Sacrifice, commonly known as Eid al-Adha, has a profound religious and cultural impact on nations with a Muslim majority. This festival is celebrated every year in Muslim countries; however, it is a time in which patients present to the emergency department with serious injuries. In our study, we examined current injuries occurring during Eid al-Adha in one of the largest hospitals in Türkiye, providing the largest patient population to date. This included mapping tendon and maxillofacial injuries, a first in the literature. To the best of our knowledge, this is the largest case series of injuries sustained during Eid al-Adha. The significance of this study lies in its potential to significantly benefit patients and healthcare systems by providing reference data. (2) Methods: Patients admitted to Ankara City Hospital during Eid al-Adha between 2019 and 2023 were examined. The demographic characteristics, injury patterns, and injury sites of patients admitted on the four days of Eid al-Adha were collected and analyzed. Maxillofacial traumas during the festival were analyzed. Tendon injuries on the left hand, which is the most commonly injured body part in the literature, were mapped into a figure. To compare the change in the number of patients, a comparison was made with the number of patients in our hospital for four consecutive days 2 weeks before Eid. Statistical analysis was performed using IBM SPSS Statistics for Windows. (3) Results: A total of 610 patients, including 101 female and 509 male patients, were included in this study. A statistically significant increase (p < 0.001 for all years) in hospital admission due to injury was observed. Individuals between the ages of 30 and 40 years were the most frequently admitted patients (n = 182, 29.8%). Knife injuries were significantly more common in all patients (p < 0.001). When the total number of patients was evaluated in terms of injured areas where patients present to the emergency department, left-hand injuries were found to be significantly more common than injuries in other areas (p < 0.001 for all). The extensor pollicus longus tendon was the most commonly injured tendon among all extensor and flexor tendon injuries (n = 104). The most commonly injured tendon was the flexor tendon in zone 2 of the first finger (n = 45). This study showed that injuries to the extensor tendon in zone 1 of the fifth finger, the flexor tendon in zone 4 of the first finger, and the flexor tendon in zone 1 of the fifth finger were never seen. Twenty-five patients with maxillofacial injuries were admitted to the hospital. Orbital floor fractures were the most common type of maxillofacial injury. The anesthesia technique we preferred for all patients was local anesthesia (n = 267). Wide-awake local anesthesia no tourniquet (WALANT) was the second most preferred anesthetic technique. The number of patients who were selected in a random 4-day period for each year were compared with the number of patients who came during Eid al-Adha. The Mann-Whitney U tests revealed a significant increase in injuries on the first day of Eid al-Adha compared to non-festival days (p < 0.001). However, no significant differences were observed on the subsequent days or in the overall injury counts during the festival period (p = 0.841 for day 2, p = 0.151 for day 3, p = 0.310 for day 4). (4) Conclusions: According to this study, which is the largest known case series in the literature, the number of patients admitted to the hospital increased annually. In our study, we observed a significant increase in injuries only on the first day of Eid al-Adha compared to a randomly selected 4-day period of the same year. Left-hand extensor tendon injuries from a knife were the most common injuries in middle-aged men. The extensor pollicis longus tendon was the most commonly injured extensor tendon, with zones 3 and 4 being the most commonly affected. The flexor pollicis longus tendon was the most commonly injured flexor tendon in zone 2. During this period, patients may not only need hand surgery but also maxillofacial plastic surgery. We recommend, in addition to the indications I,n the literature that during Eid al-Adha, the WALANT technique should be widely adopted in patients where local anesthesia will be insufficient. We also recommend utilizing a diagram to manage the patient load during Eid al-Adha and prevent overburdening the healthcare system.

Impact of Reaction Setting on the Management, Severity, and Outcome of Pediatric Food-Induced Anaphylaxis: A Cross-Sectional Study

BACKGROUND

Prompt epinephrine autoinjector (EAI) use is the primary treatment for anaphylaxis. However, limited Canadian data exist on the impact of reaction location on EAI use for food-induced anaphylaxis (FIA).

OBJECTIVE

We sought to investigate the setting, management, and severity of pediatric FIA.

METHODS

We recruited children presenting with FIA from 11 Canadian emergency departments. Patient demographics and the setting, management, and symptoms of FIA were collected by standardized questionnaire. Factors associated with prehospital EAI use and reaction severity were determined by logistic regression.

RESULTS

We recruited 3,604 children; 60.2% were male and the median age was 5.0 years (interquartile range 1.8-11.0). Among cases with a known location of FIA (85.0%), home was the most common setting (68.1%), followed by school/daycare (12.8%), other locations (11.4%; eg, park, car), and restaurants (7.4%). In the prehospital setting, EAI was administered in 36.7% of reactions at home, 66.7% in school/daycare, 40.2% in other locations, and 44.5% in restaurants. Relative to reactions occurring at school/daycare, prehospital EAI use was less likely at home (adjusted odds ratio [aOR] 0.80; 95% CI 0.76-0.84), in restaurants (aOR 0.81; 95% CI 0.75-0.87), and in other settings (aOR 0.77; 95% CI 0.73-0.83), when data were adjusted for reaction severity, sex, age, comorbidities, and province. The FIA setting was not associated with reaction severity or hospitalization.

CONCLUSIONS

Prehospital EAI use was higher at school/daycare than in other settings, potentially owing to the presence of policies and training on FIA. Setting-specific interventions including educational programs and policies/laws mandating training and stocking an EAI may improve anaphylaxis recognition and treatment.

Economic burden of food allergy in Canada: Estimating costs and identifying determinants

BACKGROUND

Limited data exist on the economic burden of food allergy (FA).

OBJECTIVE

To assess FA-related direct (healthcare and out-of-pocket) and indirect (lost productivity) costs and their determinants in Canadian children and adults self-reporting FA.

METHODS

FA-individuals self-reporting a convincing history or physician diagnosis were recruited through FA registries, an anaphylaxis registry, and advocacy associations, and electronically surveyed regarding FA-related healthcare use, out-of-pocket expenditures, and time lost from paid and unpaid labor. Direct and indirect costs (2020 Canadian dollars [CAD]) were stratified on severe reaction vs mild, moderate or no reaction, and children vs adults; multivariate regressions assessed the association between costs and sociodemographic and disease characteristics.

RESULTS

Between May 2018 and July 2019, 2692 eligible individuals responded (2189 convincing history and 503 physician diagnosis only); 1020 experienced a severe reaction; 1752 were children. Per FA-individual, annual healthcare, out-of-pocket, and indirect costs were $1267, $2136, and $7950. Those with a severe reaction had higher healthcare and out-of-pocket costs than those with mild, moderate or no reaction. FA-children vs FA-adults had higher healthcare and out-of-pocket costs, and lower indirect costs. Multivariate results showed that lower age, a severe reaction ever, multiple FAs, and fair or poor general health were associated with higher healthcare and out-of-pocket costs. Higher age, lower household education and income, and fair or poor general health were associated with higher indirect costs.

CONCLUSION

The economic burden of FA in Canada is substantial, particularly for those with a severe reaction ever, multiple FAs, and fair or poor general health. It is crucial that those most adversely affected are allocated appropriate resources to support disease management.

Fruit-Induced Anaphylaxis: Clinical Presentation and Management

BACKGROUND

Data are sparse regarding the clinical characteristics and management of fruit-induced anaphylaxis.

OBJECTIVE

To assess clinical characteristics and management of patients with fruit-induced anaphylaxis and determine factors associated with severe reactions and epinephrine use.

METHODS

Over 9 years, children and adults presenting with anaphylaxis to seven emergency departments in four Canadian provinces and patients requiring emergency medical services in Outaouais, Quebec were recruited as part of the Cross-Canada Anaphylaxis Registry. A standardized form documenting symptoms, triggers, and management was collected. Multivariate logistic regression was used to identify factors associated with severe reactions and epinephrine treatment in the pre-hospital setting.

RESULTS

We recruited 250 patients with fruit-induced anaphylaxis, median age 10.2 years (interquartile range, 3.6-23.4 years); 48.8% were male. The most common fruit triggers were kiwi (15.6%), banana (10.8%), and mango (9.2%). Twenty-three patients reported having eczema (9.3%). Epinephrine use was low in both the pre-hospital setting and the emergency department (28.4% and 40.8%, respectively). Severe reactions to fruit were more likely to occur in spring and among those with eczema (adjusted odds ratio [aOR] = 1.12, 95% confidence interval [CI], 1.03-1.23; and 1.17, 95% CI, 1.03-1.34, respectively). Patients with moderate and severe reactions (aOR = 1.23; 95% CI, 1.06-1.43) and those with a known food allergy (aOR = 1.38; 95% CI, 1.24-1.54) were more likely to be treated with epinephrine in the pre-hospital setting.

CONCLUSIONS

Severe anaphylaxis to fruit is more frequent in spring. Cross-reactivity to pollens is a potential explanation that should be evaluated further.
