Expression and prognosis of DSG-2, CXADR, CD46 in head and neck squamous cell carcinoma.

Objectives: Investigating the expression and prognostic significance of adenovirus receptors DSG-2, CXADR and CD46 in head and neck cancer.

Methods: 104 patients with HNSCC (77 OPSCC, 27 LSCC) were retrospectively included in the study. Immunohistochemical staining was performed on all selected slides to detect the expression of DSG-2, CXADR, CD46 and the immunoreactive score (IRS) was determined from the number of positively stained tumor cells and their staining intensity.

Simple, low-cost, and well-performing method, the outgrowth technique, for the isolation of cells from nasal polyps.

Background: Epithelial cells are an important part of the pathomechanism in chronic rhinosinusitis with nasal polyps. It is therefore essential to establish a robust method for the isolation and culture of epithelial cells from nasal polyps to enable further research. In this study, the feasibility of the outgrowth technique for the isolation of the epithelial cells from the nasal polyps was evaluated.

Long-Term Cryopreservation of Nasal Polyp Tissue in a Biobank for the Isolation and Culture of Primary Epithelial Cells.

Epithelial cells may play an important role in the pathologic process of chronic rhinosinusitis with nasal polyps. Therefore, providing epithelial cells from a biobank could greatly contribute to further research. In the present work, the isolation of epithelial cells from long-term cryopreserved tissue is demonstrated.

[Syphilis infection in the ENT area].

The number of reported cases of syphilis has been increasing for years. The sexually transmitted disease is caused by the spirochete Treponema pallidum subspecies pallidum and progresses in different stages. Symptoms in the ENT area can occur in all stages.
