Introduction: Eosinophilic chronic rhinosinusitis with nasal polyps (CRSwNP) is frequently associated with greater inflammation, poorer prognosis, and a high recurrence rate after sinus surgery.
Objective: This study evaluated the clinical and imaging characteristics of eosinophilic CRSwNP in patients aged 12-17.
Methods: We retrospectively enrolled 139 patients aged 12-17 with bilateral CRSwNP. Clinical characteristics, computed tomography (CT) features, tissue eosinophil counts, and eosinophil activity were evaluated.
Results: Twenty-three (16.5%) patients had recurrent nasal polyps that required revision surgery. Patients requiring revision surgery had higher tissue eosinophil infiltration in the sinus mucosa than those not requiring revision surgery. The optimal cut-off value to distinguish the need for revision surgery was a tissue eosinophil count > 21.5/high-power field determined by the receiver operating characteristic curve. The Lund-Mackay and olfactory cleft opacification scores on CT images were significant predictors of tissue eosinophil count in the univariate analysis, and only olfactory opacification scores remained statistically significant in the multivariate analysis.
Conclusion: This study revealed that the CT feature of the olfactory cleft opacification score could be a significant characteristic of eosinophilic CRSwNP in adolescents.

We identified a novel herpesvirus in 2 deceased captive blue penguins (). Moderate-to-severe myocardiocyte atrophy and necrosis, and eosinophilic intranuclear inclusion bodies (INIBs), were seen in myocardiocytes in one bird; reticuloendothelial (RE) cell INIBs and multifocal RE cell necrosis were seen in both birds. The histologic findings were suggestive of viral infection.

Chronic hypereosinophilia, defined as persistent elevated blood levels of eosinophils ≥1,500/μL, is associated with tissue infiltration of eosinophils and consequent organ damage by eosinophil release of toxic mediators. The current therapies for chronic hypereosinophilia have limited success, require repetitive administration, and are associated with a variety of adverse effects. As a novel approach to treat chronic hypereosinophilia, we hypothesized that adeno-associated virus (AAV)-mediated delivery of an anti-human eosinophil antibody would provide one-time therapy that would mediate persistent suppression of blood eosinophil levels.

Background: Eosinophilic esophagitis (EoE) is a chronic T helper type 2 (Th2)-associated inflammatory disorder triggered by food allergens, resulting in esophageal dysfunction through edema, fibrosis, and tissue remodeling. The role of epithelial remodeling in EoE pathogenesis is critical but not fully understood.
Objective: To investigate the role of epithelial IKKβ/NFκB signaling in EoE pathogenesis using a mouse model with conditional Ikkβ knockout in esophageal epithelial cells (Ikkβ).

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is a rare type of primary salivary gland-type tumor of the lung. HCCC is characterized by unique pathological features, including nests, cords, or trabeculae of clear or eosinophilic tumor cells infiltrating a mucinous or hyalinized stroma. Additional analyses of this carcinoma have revealed positive epithelial markers via immunophenotyping and gene translocation through genetic testing.

While the Banff classification dichotomizes kidney allograft rejection based on the localization of the cells in the different compartments of the cortical kidney tissue [schematically interstitium for T cell mediated rejection (TCMR) and glomerular and peritubular capillaries for antibody-mediated rejection (AMR)], there is a growing evidences that subtyping the immune cells can help refine prognosis prediction and treatment tailoring, based on a better understanding of the pathophysiology of kidney allograft rejection. In the last few years, multiplex IF techniques and automatic counting systems as well as transcriptomics studies (bulk, single-cell and spatial techniques) have provided invaluable clues to further decipher the complex puzzle of rejection. In this review, we aim to better describe the inflammatory infiltrates that occur during the course of kidney transplant rejection (active AMR, chronic active AMR and acute and chronic active TCMR).
