An International Delphi Consensus on the Management of Pollen-Food Allergy Syndrome: A Work Group Report of the AAAAI Adverse Reactions to Foods Committee.

Background: Pollen-food allergy syndrome (PFAS) is common among patients with allergic rhinitis. Treatment recommendations for patients with PFAS remain variable.

Objective: To develop consensus recommendation statements for managing patients with PFAS.

A Cricopharyngeal Bar as an Underrecognized Finding in an Adolescent with Eosinophilic Esophagitis.

A 16-year-old Caucasian male with previously diagnosed eosinophilic esophagitis (EoE) 4 years before his initial visit to an allergist-immunologist, scheduled due to severe dysphagia and recurrent food impaction. He had been off EoE therapy for 1 year. After resuming inhaled fluticasone and a proton pump inhibitor (PPI), esophagogastroduodenoscopy (EGD) was immediately scheduled.

Biomarkers in asthma, potential for therapeutic intervention.

Asthma is a heterogeneous disease characterized by multiple phenotypes with varying risk factors and therapeutic responses. This Commentary describes research on biomarkers for T2-"high" and T2-"low" inflammation, a hallmark of the disease. Patients with asthma who exhibit an increase in airway T2 inflammation are classified as having T2-high asthma.

An a Priori Approach to Small Airway Dysfunction in Pediatric Asthmatics.

Small airway dysfunction remains a stepchild in the pediatric asthma care pathway. In brief, elements of the pulmonary function test (PFT) concerning smaller airway data remain less utilized. To further the value of the standard PFT we underwent a prospective Proof of Concept (POC) project, utilizing the outpatient performance of PFT tests in children 6-18 years during a 15-month period.

Atopic Dermatitis is More than Skin Deep: A Commentary on Atopic Dermatitis and Review of Pertinent Publications from 2019-2021.

The journal has a significant publication record on the topic of Atopic Dermatitis (AD) the past four years [...

Persistent Hyper IgA as a Marker of Immune Deficiency: A Case Report.

An elevated IgA level obtained in a 10-year-old male a year after an episode of pneumococcal sepsis led to the discovery of a broad-based IgG-specific antibody deficiency syndrome. The specifics of the case and pertinent literature are presented, including a discussion of the hyper-IgD syndrome. An elevated IgA, greater than two standard deviations above the expected age range should prompt a complete workup for selective antibody deficiency syndrome and adds an additional associated marker of an indolent hyper-IgD syndrome in a different clinical circumstance, although the lack of antibody response to vaccines is atypical of the hyper-IgD syndrome.

Development of a core outcome set for therapeutic studies in eosinophilic esophagitis (COREOS).

Background: End points used to determine treatment efficacy in eosinophilic esophagitis (EoE) have evolved over time. With multiple novel therapies in development for EoE, harmonization of outcomes measures will facilitate evidence synthesis and appraisal when comparing different treatments.

Objective: We sought to develop a core outcome set (COS) for controlled and observational studies of pharmacologic and diet interventions in adult and pediatric patients with EoE.

A compendium and review of pediatric pulmonary function testing assessment opportunities for asthma.

Objective: Standard spirograms are widely used in the respiratory disease management community to help diagnosis asthma and provide longitudinal information. Surprisingly, basic information obtained on the spirogram, beyond the FEV and change in FEV after bronchodilator is underutilized. We reviewed information on pulmonary function and bronchodilator response in children since 2016.

Hypersensitivity Reactions: An Everyday Occurrence in Pediatric Allergy Clinics.

The explanation of hypersensitivity reactions has long relied on the classification of Gell and Coombs, originally proposed in the 1960s. However, their concepts were predated by other authors by at least 50 years. A 21st century pediatric allergy clinic provides multiple examples of these basic concepts on a daily basis.

Small Airway Disease in Pediatric Asthma: the Who, What, When, Where, Why, and How to Remediate. A Review and Commentary.

Asthma affects all portions of the airways. Small airways, however, comprise a substantial component of the conducting lung air flow. In asthma, inflammatory processes can affect the whole respiratory tract, from central to peripheral/small airways.

Role of innate lymphoid cells in allergic diseases.

Over the past decade, there has been increasing interest and research into understanding the type 2 immune responses by the epithelium-derived cytokines interleukin (IL) 33, IL-25, and thymic stromal lymphopoietin. Innate lymphoid cells (ILC) are a unique family of effector immune cells that functionally resemble T cells but lack clonal distributed antigen receptors. Group 2 ILCs, ILC2s, are known for their capability to secrete proallergic cytokines, including IL-5 and IL-13.

Prevalence of asthma among school children in Gaborone, Botswana.

Background: Asthma prevalence is high (>10%) in developed countries and although data is still missing for most of Africa, rates are increasing in developing regions as they become more westernized. We investigated the prevalence of asthma in school children in Gaborone, Botswana.

Methods: This was a cross sectional descriptive study.

Fifty Years of Chronic Rhinosinusitis in Children: The Accepted, the Unknown, and Thoughts for the Future.

Chronic sinusitis is an often-used term in both lay and medical circumstances. In children, it has significant but largely undefined healthcare costs. Chronic rhinosinusitis (CRS) in children has well demarcated time periods and symptoms, although the actual pathway from normal sinus to CRS is not well understood.

A literature review of the evidence that a 12% improvement in FEV1 is an appropriate cut-off for children.

Introduction: A well-performed spirometry, using a change in forced expiratory volume in one second (FEV(1)) after albuterol, is commonly used to support the likelihood of an asthma diagnosis. The current standard, accepted by the 2007 National Heart Lung and Blood Institute Asthma Expert Panel Report-3 (EPR-3) guidelines, is a 12% improvement in the FEV(1) after a bronchodilator.

Objective: We sought to determine whether existing studies support or refute using a 12% improvement as a significant change in FEV(1) in children and adolescents.

Twin and family studies reveal strong environmental and weaker genetic cues explaining heritability of eosinophilic esophagitis.

Background: Eosinophilic esophagitis (EoE) is a chronic antigen-driven allergic inflammatory disease, likely involving the interplay of genetic and environmental factors, yet their respective contributions to heritability are unknown.

Objective: To quantify the risk associated with genes and environment on familial clustering of EoE.

Methods: Family history was obtained from a hospital-based cohort of 914 EoE probands (n = 2192 first-degree "Nuclear-Family" relatives) and an international registry of monozygotic and dizygotic twins/triplets (n = 63 EoE "Twins" probands).

Intermittence for humans spreading 45,000 years ago: from Eurasia to the Americas.

From northeastern Eurasia to the Americas, a three-stage spread of modern humans is considered through large-scale intermittence (exploitation/relocation). Conceptually, this work supports intermittence as a real strategy for colonization of new habitats. For the first stage, northeastern Eurasia travel, we adapt our model to archaeological dates determining the diffusion coefficient (exploitation phase) as D = 299.

Digit ratio (2D:4D), aggression, and testosterone in men exposed to an aggressive video stimulus.

The relative lengths of the 2(nd) and 4(th) digits (2D:4D) is a negative biomarker for prenatal testosterone, and low 2D:4D may be associated with aggression. However, the evidence for a 2D:4D-aggression association is mixed. Here we test the hypothesis that 2D:4D is robustly linked to aggression in "challenge" situations in which testosterone is increased.

Oral vascular malformation in a patient with hereditary hemorrhagic telangiectasia: a case report.

Hereditary hemorrhagic telangiectasia (HHT) is an inherited mucocutaneous disease characterized by recurrent epistaxis, lesions on skin and oral mucosa, and arteriovenous malformations of the soft tissues. This article describes the treatment of a 64-year-old woman with a bleeding nodule, which was diagnosed as an arteriovenous malformation of the gingival mucosa. She was treated using sclerotherapy.
