INTRODUCTION: Bleeding is a common concern during functional endoscopic sinus surgery (FESS) that can increase the risk of damage to adjacent vital elements by reducing the surgeon's field of view. This study aimed to explore the efficacy of topical tranexamic acid in reducing intraoperative bleeding. MATERIALS AND METHODS: This double-blind, randomized clinical trial was conducted in 60 patients with chronic rhinosinusitis with polyposis (CRSwP) who underwent FESS...

Peutz-Jeghers syndrome (PJS) is a rare hereditary disorder characterized by hamartomatous polyps in both of the gastrointestinal tract and mucosal pigmentation. It could increase in risk of intestinal and extra-intestinal neoplasms. We here described three cases of sinonasal polyposis in a PJS family and two developed sinonasal type adenocarcinoma. Genetic study revealed a germline STK11/LKB1 mutation on codon 179 (c.C536G, p.P179R) of exon 4. LOH analysis of the LKB1 locus confirms this to be a deleterious mutation...

The pathogenesis of nasal polyp is to be further investigated. Micro RNA (miR) plays a role in the development of allergic inflammation. Interleukin (IL)-10-producing dendritic cells (DC) have immune tolerogenic properties. This study test a hypothesis that miR-17-92 cluster is associated with suppressing IL-10 in peripheral DC. In this study, peripheral blood samples were obtained from 26 patients with nasal polyp. The CD11c DCs were isolated from the blood samples and analyzed for the expression of IL-10...

BACKGROUND/OBJECTIVES: Epithelial-mesenchymal transition (EMT) is involved in not only cancer development and metastasis but also non-cancerous conditions. Hypoxia is one of the proposed critical factors contributing to formation of chronic rhinosinusitis or nasal polyposis. Wheatgrass (Triticum aestivum) has antioxidant, anti-aging, and anti-inflammatory effects. In this study, we analyzed whether wheatgrass has an inhibitory effect on the EMT process in airway epithelial cells. MATERIALS/METHODS: A549 human lung adenocarcinoma cells were incubated in hypoxic conditions (CO2 5%/O2 1%) for 24 h in the presence of different concentrations of wheatgrass extract (50, 75, 100, and 150 µg/mL) and changes in expression of epithelial or mesenchymal markers were evaluated by immunoblotting and immunofluorescence...

INTRODUCTION: Chronic Rhino Sinusitis (CRS) is one of the most prevalent chronic illnesses across the globe, affecting persons of all ages. It is an inflammatory process that involves the paranasal sinuses with symptoms lasting longer than 12 weeks. AIM: To establish the significance of blood eosinophil (count) levels in CRS with nasal polyps and to compare blood eosinophil count with eosinophil count in the histopathology specimens of the polyps. MATERIALS AND METHODS: This was a retrospective study done to review the medical records of 63 patients who underwent endoscopic sinus surgery for CRS with Nasal polyps...

The emergence of microfluidic epithelial models using diverse types of cells within a physiologically relevant microenvironment has the potential to be a powerful tool for preclinical drug screening and pathophysiological studies. However, to date, few studies have reported the development of a complicated in vitro human nasal epithelial model. The aim of this study was to produce an in vitro human nasal mucosa model for reliable drug screening and clinical applications. Here, we integrated and optimized several culture conditions such as cell type, airway culture conditions, and hydrogel scaffolds into a microfluidic chip to construct an advanced in vitro human nasal mucosa model...

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a group of multifactorial and heterogeneous disorders with a significant economic strain on society, likely made up of different endotypes, each with a unique pathomechanism. In addition to the traditional clinical measures, there is a recognized need for reliable biomarkers to provide predictive information regarding diagnosis, endotypes, treatment responses, and future risk of recurrence. Fueled by the advances in basic research, various biomarkers have been explored in recent years...

Patients with severe asthma represent a minority of the total asthma population, but carry a majority of the morbidity and healthcare costs. Achieving better asthma control in this group of patients is therefore of key importance. Systematic assessment of patients with possible severe asthma to identify treatment barriers and triggers of asthma symptoms, including co-morbidities, improves asthma control and reduces healthcare costs and is recommended by international guidelines on management of severe asthma...

Asthma is a highly prevalent chronic disease of the airways; approximately 10% of patients with asthma will experience a severe form of the disease. New understanding of the pathogenesis of asthma has enabled the development of novel drugs and provided hope for patients with asthma. Interleukin (IL)-5 and IL-5 receptor subunit α (IL-5-Rα) plays a crucial role in the development, maturation, and operation of eosinophils so were the first important therapeutic target of these new drugs. While the results of early clinical trials of these drugs were not promising, results improved once researchers discovered the drugs worked best in patients with high eosinophil levels...

Allergy results from an aberrant Type 2 inflammatory response, triggered by a wide range of environmental antigens (allergens) that lead to various immune responses, culminating in the production of immunoglobulin E (IgE). Two key cytokines, interleukin (IL)-4 and IL-13, are critical to the induction and perpetuation of the Type 2 response, and have been implicated in multiple atopic diseases. Area covered: This review summarizes recent milestone developments that have elucidated components of the pathogenesis of atopic diseases such as atopic dermatitis (AD), asthma, and chronic sinusitis with nasal polyposis (CSwNP)...

BACKGROUND: Although studies have reported an association between air pollutants and increased allergic airway diseases, such as allergic rhinitis and nasal polyposis, the underlying mechanisms are not fully understood. A limited number of studies have suggested that diesel exhaust particles (DEP) play a role in atopy and the pathogenesis of allergic upper airway diseases. The aim of this study was to investigate the effect of DEP on inflammatory cytokine release, and mRNA expression of transcription factors such as JNK and NF-β in primary nasal epithelial cells (NECs), in vitro...
