Article Synopsis
- A 28-year-old male experienced a rare giant cell tumor in the larynx after undergoing a total thyroidectomy in June 2022 for a thyroid mass, which was later diagnosed as a giant cell tumor of soft tissues.
- He was readmitted in June 2023 due to the recurrence of a neck mass and underwent surgery (partial laryngectomy and partial hypopharyngectomy) to remove the tumor completely.
- Following the surgery, the mass was confirmed as a giant cell tumor of the larynx through various testing methods, and after 12 months of follow-up, the patient showed no signs of tumor recurrence without undergoing any radiotherapy or chemotherapy.
Characterizing the Neutrophilic Inflammation in Chronic Rhinosinusitis With Nasal Polyps.
Front Cell Dev Biol
December 2021
The mechanisms underlying neutrophilic inflammation in chronic rhinosinusitis with nasal polyps (CRSwNP) remain poorly investigated. This study aimed to examine the factors that contribute to tissue neutrophilia in CRSwNP. The numbers of neutrophils and active caspase-3-positive apoptotic neutrophils in sinonasal tissues were assessed via immunofluorescence staining.

Objective: To explore the influence of asthma and chronic obstructive pulmonary disease (COPD) comorbidity on disease expression and outcomes, and the potential underlying mechanisms in COVID-19 patients.
Methods: A total of 961 hospitalized COVID-19 patients with a definite clinical outcome (death or discharge) were retrospectively enrolled.
Background: The mechanisms underlying mucosal eosinophilia in chronic rhinosinusitis with nasal polyps (CRSwNP) remain poorly clarified. The nervous system and neuropeptides play an important role in the regulation of immune response. Herein we explore the expression and function of hemokinin-1 (HK-1), a newly identified tachykinin, along with its receptor neurokinin 1 receptor (NK1R) in CRSwNP.

November 2018
Background: Although upregulated expression of local IgD has been reported in patients with chronic rhinosinusitis (CRS), its function is unclear.
Objective: We sought to explore the expression and function of soluble IgD in patients with CRS, particularly CRS with nasal polyps.
Methods: IgD levels in sinonasal mucosa were analyzed by using RT-PCR and ELISA.
