The nasal epithelium is the primary point of contact for inhaled respiratory viruses such as rhinovirus, respiratory syncytial virus, influenza, and coronavirus, among others. In order to establish infection, these viruses must engage their respective receptors located on host epithelial cells and begin replication. However, the nasal epithelium is also a pivotal orchestrator of both structural and innate immune defenses against these pathogens and thus mounts a broad antiviral response to halt the progression of the infection into the lower airways. Of note, the most common virus found in the airways of children presenting to the hospital emergency department with acute wheezing and asthma is rhinovirus C (RV-C), followed by rhinovirus A (RV-A). Here, we illustrate infection of a preclinical differentiated nasal epithelial model with clinical isolates of RV-A and -C, in conjunction with several methods utilized for characterization of epithelial responses post-infection in vitro.

Objective: This study aimed to investigate the long-term effects of different suture and graft techniques on postoperative projection and rotation.
Methods: A total of 392 patients who met the inclusion criteria were screened and divided into 9 groups based on the technique performed. Outcome scores, tip projection ratios, and tip rotation angles were measured for the preoperative, early postoperative, and late postoperative periods.

Frequent emergence of respiratory viruses with pandemic potential, like SARS-CoV-2 or influenza, underscores the need for broad-spectrum prophylaxis. Existing vaccines show reduced efficacy against newly emerged variants, and the ongoing risk of new outbreaks highlights the importance of alternative strategies to prevent infection and viral transmission. As respiratory viruses primarily enter through the nose, formulations targeting the nasal epithelium are attractive candidates to neutralize pathogens and thus prevent or minimize infection.

Background: Currently, most researchers apply pollen extracts or -suspensions to assess the effects of pollen exposure on airway epithelia. How respiratory epithelia respond to pollen aerosols is not well studied because standardised methods to aerosolize pollen were not available until recently.
Aim Of Study: To develop and test a near-natural exposure model for pollen grains based on differentiated human nasal epithelial cells and a novel particle aerosoliser.

Rationale: Extranodal natural killer (NK)/T-cell lymphoma is an uncommon non-Hodgkin lymphoma, prevalent in Asia. It often involves the nasal and upper airway regions but can disseminate to other sites like skin, soft tissue, testis, and gastrointestinal tract, characterized by Epstein-Barr virus association.
Patient Concerns: This report discusses a 48-year-old male initially diagnosed with Behcet syndrome with dry mouth, uveitis, pruritic macules, and human leukocyte antigen-B51 positivity.

Extranodal natural killer/T-cell lymphoma (ENKTCL), nasal type, is a rare and aggressive subtype of non-Hodgkin's lymphoma that often presents with extranodal involvement. While relapse patterns commonly involve the nasal cavity, lungs or skin, cardiac involvement is rare. We report a late 50-year-old patient with ENKTCL, nasal type, who achieved complete remission following chemotherapy and autologous stem cell transplantation.
