AbstractWe studied the introduction rate after a negative challenge to mixed tree nut biscuit. This is a retrospective review of patients who underwent and passed mixed tree nut biscuit challenges performed at Princess Margaret Hospital (PMH) between 2016 and 2018. Follow-up phone calls were made to families to ascertain if the tree nuts included in the tree nut biscuit were still included in the child’s diet 1 to 3 years following negative oral food challenge (OFC). A total of 162 children underwent mixed tree nut biscuit challenge between 2016 and 2018 at Princess Margaret Hospital, Perth, Western Australia. A total of 141 (87%) passed mixed tree nut biscuit challenge. Of the 133 children that were contacted (8 children could not be contacted), 104 children still included some or all of the challenge nuts in the child’s diet; with 24 children completely eliminating the challenge nuts (18%), 5 children eliminated some of the challenge nuts (3.5%). We found a high introduction rate (82%); however, some families may require more support to maintain the tree nuts in the child’s diet following a negative OFC.

Background: The oral food challenge (OFC) in IgE mediated food allergy causes anxiety both in parents and in patients due to its inherent risks.Objective: Documentation of the rate, spectrum, and predictors of positive reactions is instructive.Methods: Children, who underwent OFC between January 1, 2017 and December 31, 2019 were analyzed.Results: A total of 1361 OFCs in 613 cases were reviewed. Most of them were performed in preschool children (≤2 years 50%) and 55% of them had more than one OFC. Mainly consid-ered food groups were cow’s milk (31.8%), hen’s egg (28.5%), tree nuts (20%), legumes (7%), seeds (4.9%), and wheat (2.7%). The overall OFC positivity was 9.6%, whereas 6.7% with cow’s milk, 4.9% with hen’s egg, 16.1% with tree nuts, 21.6% with wheat, and 32.8% with seeds. The severity scoring revealed grade I (24.4%), II (45.8%), and III (29.7%) reactions. Fifty (38%) cases required epinephrine and four cases required hospitalization. OFCs with sesame seeds (odds ratio [OR]: 7.747, [confidence interval (CI) 95%: 4.03–14.90]), wheat (OR: 3.80, [CI: 1.64–8.84]), and tree nuts (OR: 2.78, [CI: 1.83–4.23]) predicted a positive OFC while a concomitant asthma (OR: 3.61 [CI: 1.27–10.28]) was more likely to elicit anaphylaxis.Conclusion: In OFC practice, priority is given to basic nutritional sources and the most frequent food allergens, where preschool children with multiple sensitizations are the primary subjects. Increased risks of positive reactions with sesame, tree nut, and wheat and increased risk of anaphylaxis with concomitant asthma should be considered while performing OFC.

Abstract Background The prevalence of food allergy in Canada is high and has increased over time. To date, there are no Canadian data on the healthcare costs of visits to allergists. Methods We sent an anonymous survey to allergist members of the Canadian Society of Allergy and Clinical Immunology (CSACI) between October and December 2019. Survey questions included demographic information and billing fees for various types of allergy visits and diagnostic testing. Results Of 200 allergists who are members of CSACI, 43 allergists responded (21.5% response rate). Billing fees varied widely. The greatest ranges were noted for oral immunotherapy (OIT; both initial consultation [mean $198.70; range $0 to $575] and follow up/build up visits [mean $125.74; range: $0 to $575]). There were significant provincial differences in billing fees, as well as significant billing fee differences between hospital versus community allergists (e.g. oral food challenge [OFC]: $256.38 vs. $134.94, p < 0.01). Billing fees were higher outside of Ontario, with the exception of specific Immunoglubulin E (sIgE) testing and OIT visits. Conclusions Greater standardization of billing fees across provinces and between hospital versus community allergy could result in more consistency of billing fees for OFC and OIT across Canada. Further knowledge of exact costs will help inform practice and policy in the diagnosis and management of food allergy.

AbstractReports of incidental pneumomediastinum in infants secondary to inflicted trauma are limited. A retrospective review of infants with pneumomediastinum and history of inflicted trauma was performed. A comprehensive literature review was performed. Three infants presented with pneumomediastinum associated with inflicted trauma. Mean age was 4.6 weeks. All patients underwent diagnostic studies, as well as a standardized evaluation for nonaccidental trauma. All patients with pneumomediastinum were resolved at follow-up. Review of the literature identified other cases with similar presentations with related oropharyngeal injuries. Spontaneous pneumomediastinum in previously healthy infants may be associated with inflicted injuries. Clinicians should be aware of the possibility of an oropharyngeal perforation related to this presentation.
