Socioeconomic and Ethnic Disparities in Timing and Outcome of Interarytenoid Injection Augmentation.

Objectives: To investigate the relationship between social determinants of health and timeliness of management, adherence to follow-up, and outcomes of treatment with interarytenoid injection augmentation (IAIA).

Methods: Retrospective cohort study of all pediatric patients treated with IAIA at a large pediatric institution's multidisciplinary aerodigestive clinic between August 2022 and February 2024. Retrieved demographic factors, dates of referral, consultation, treatment, and follow-up, as well as objective measures of dysphagia and aspiration via videofluoroscopic swallow study (VFSS) reports, using dysphagia outcome and severity scale (DOSS) scores and the greatest unsafe thickness, or 'aspiration score'.

Assessing the Effect of Infant Peanut Exposure Guidelines on Peanut Aspiration Using Google Trends Search Analysis.

Background The American Academy of Pediatrics (AAP) changed guidelines in 2017 to recommend introducing infants to peanuts as early as four months. Peanuts are also one of the most commonly aspirated food-related foreign bodies. Google Trends search pattern analysis has been validated in epidemiologic research as being reflective of healthcare events.

Learning early about peanut-triggered food protein-induced enterocolitis syndrome.

Background: Food protein-induced enterocolitis syndrome (FPIES) is a non-immunoglobulin E mediated food allergy that typically presents with repetitive emesis and may be associated with lethargy, marked pallor, hypotension, hypothermia, and/or diarrhea. Although many foods are known to cause FPIES, peanut-triggered FPIES is emerging due to changes in the feeding practice guidelines, which recommends early peanut introduction in infants.

Objective: We aimed to characterize peanut-triggered acute FPIES cases in our pediatric population and to describe their attributes, treatment, and outcomes.

International Consensus Recommendations for Eosinophilic Gastrointestinal Disease Nomenclature.

Background & Aims: Substantial heterogeneity in terminology used for eosinophilic gastrointestinal diseases (EGIDs), particularly the catchall term "eosinophilic gastroenteritis," limits clinical and research advances. We aimed to achieve an international consensus for standardized EGID nomenclature.

Methods: This consensus process utilized Delphi methodology.

Diagnosis of Pediatric Non-Esophageal Eosinophilic Gastrointestinal Disorders by Eosinophil Peroxidase Immunohistochemistry.

Background: Diagnosis of non-esophageal eosinophilic gastrointestinal disorders requires quantification of tissue eosinophils. Our objective was to evaluate eosinophil peroxidase (EPX) immunohistochemistry (IHC) as a method for histologic diagnosis of eosinophilic gastritis (EG) and eosinophilic duodenitis (EoD).

Methods: We performed a retrospective analysis of biopsies from pediatric EG/EoD cases and controls.

Deep interarytenoid notch in young children managed with systematic thickener wean and injection laryngoplasty.

Objectives: Deep interarytenoid notch (DIN) is a congenital variation of the larynx often associated with dysphagia and aspiration (DA) in young children. Feeding therapy with thickeners and surgical management with injection larygoplasty (IL) are used with various efficacies. Thickeners address the functional domain and IL addresses the anatomical domain of treatment.

Infliximab-Associated Immunomediated Hepatitis in Children With Inflammatory Bowel Disease.

Infliximab (IFX) is commonly used to induce and maintain remission in inflammatory bowel disease (IBD). We report the first 2 cases of children with ulcerative colitis who had normal liver transaminases before IFX and were diagnosed with immunomediated hepatitis after IFX induction. Both the cases had negative antibodies for antinuclear, smooth muscle, and liver kidney microsome, with 1 patient having positive autoimmune serology (dsDNA) and overlap primary sclerosing cholangitis.

Esophageal microbiome in eosinophilic esophagitis.

Objective: The microbiome has been implicated in the pathogenesis of a number of allergic and inflammatory diseases. The mucosa affected by eosinophilic esophagitis (EoE) is composed of a stratified squamous epithelia and contains intraepithelial eosinophils. To date, no studies have identified the esophageal microbiome in patients with EoE or the impact of treatment on these organisms.

Esophageal human β-defensin expression in eosinophilic esophagitis.

Background: Defensins are antimicrobial peptides expressed on mucosal surfaces that contribute to maintaining intestinal homeostasis by providing innate defense mechanisms for the epithelia. Defensin expression is altered in a number of diseases that affect mucosal surfaces, such as atopic dermatitis, allergic rhinitis, and inflammatory bowel disease. Similar to atopic dermatitis, eosinophilic esophagitis (EoE) is a chronic disease in which the squamous epithelial surface is affected by a similar TH2 microenvironment and eosinophil-predominant inflammation.

CT imaging features of eosinophilic colitis in children.

Background: Eosinophilic colitis (EC) is a gastrointestinal disease of undetermined etiology whose clinical features overlap with those of the inflammatory bowel diseases. To the best of our knowledge, the CT imaging features of EC have not been described in children.

Objective: To report and analyze the clinical, imaging and histological findings in seven children with EC.

Effect of proton pump inhibitor on esophageal eosinophilia.

Objective: Differentiation between the common etiologies of dense esophageal eosinophilia such as gastroesophageal reflux disease (GERD) and eosinophilic esophagitis can be difficult. We hypothesized that histologic features may provide diagnostic clues concerning the etiology of esophageal eosinophilia.

Methods: : We performed a retrospective chart review of 204 children with the diagnosis of esophagitis characterized by ≥ 15 eosinophils (eos) per high-power field (HPF) in at least 1 biopsy.

Novel device to sample the esophageal microbiome--the esophageal string test.

A growing number of studies implicate the microbiome in the pathogenesis of intestinal inflammation. Previous work has shown that adults with esophagitis related to gastroesophageal reflux disease have altered esophageal microbiota compared to those who do not have esophagitis. In these studies, sampling of the esophageal microbiome was accomplished by isolating DNA from esophageal biopsies obtained at the time of upper endoscopy.

The oesophageal string test: a novel, minimally invasive method measures mucosal inflammation in eosinophilic oesophagitis.

Objective: Eosinophil predominant inflammation characterises histological features of eosinophilic oesophagitis (EoE). Endoscopy with biopsy is currently the only method to assess oesophageal mucosal inflammation in EoE. We hypothesised that measurements of luminal eosinophil-derived proteins would correlate with oesophageal mucosal inflammation in children with EoE.

Recent advances in the treatment of eosinophilic esophagitis.

First described nearly 20 years ago, eosinophilic esophagitis (EoE) is an inflammatory disease of the esophagus characterized by eosinophilic infiltration of the esophageal epithelium. Over 50% of the current literature on EoE has been published in the last 3 years, signaling both a rising incidence and increased recognition of this disorder. Treatment options available for patients with EoE include dietary management and/or pharmacologic therapy.
