Pets can be \"allergy friends\" through mechanisms related to hygiene hypothesis and translational aspects, the dual role of IgG4 antibodies for pets, and their promising role as healthcare service animals (dogs). On the contrary, animals can be \"allergy enemies\" when inducing allergic sensitization and  respiratory symptoms (sometimes leading to severe reactions), and also due to cross reactivity with other pets allergens, indirect exposure and ubiquity of their allergens, cross reactivity between Can f 5 and human prostate-specific antigen (PSA). Moreover, in some cases they can trigger anaphylaxis, induce occupational asthma, and act as pests. Finally, we must outline the modest efficacy of allergen immunotherapy (AIT) for their allergens. From a strictly allergological perspective, it is evident that the \"negative\" aspects resulting from exposure to domestic / non-domestic animals outweigh the \"positive\" aspects.

Data on epidemiology of anaphylaxis are difficult to record. During the lockdown in 2020-2021 due to Coronavirus disease 2019 (COVID-19), referrals to Emergency Department (E.D.) reduced. The aims of the study are to determine anaphylaxis frequency before and during COVID-19 pandemic and risk factors for severity. <b>Methods</b>. Clinical records from a general E.D. of Milan in Italy were retrospectively evaluated before (2018-2019) and during the COVID-19 pandemic (2020-2021) analyzing demographic data, comorbidities, chronic therapies, causes, severity and adrenaline use. <b>Results</b>. The frequency of anaphylaxis remained stable (120/104129 = 0.12% in 2018-2019; 72/66720 = 0.11% in 2020-2021). No differences in the occurrence of anaphylaxis were found in sex and mean age. The main causes of anaphylaxis were food (2018-2019: 53% vs 2020-2021: 51%) and drugs (2018-2019: 27% vs 2020-2021: 33%).

Angiotensin II receptors blockers, β-blockers, diuretics and proton pump inhibitors were associated with increasing severity (p<0.01).

This study aimed to evaluate pediatricians and allergists' chosen method in children under 5 years: MDI with spacer or nebulizer. <b>Methods.</b> A brief survey was sent via electronic mail to a randomly selected group of pediatricians and allergists. There was a 15.8% (430/2718) total response rate. We divided respondents into 2 groups. Group A comprised 289 primary care pediatricians, and Group B included 141 practicing allergists. <b>Results.</b> In Group A, 68.5% (196/286) respondents indicated an MDI with spacer as their method of choice to deliver bronchodilator therapy during an asthma exacerbation; 64.7% (187/289) reported an MDI with spacer is an effective method; and 48% (135/281) believe delivering medication through a nebulizer will produce increased adverse effects than MDIs with spacers.
