Rhinoplasty via the midface degloving approach for nasal deformity due to nasal polyps: A case report of Woakes’ syndrome

Oral and Maxillofacial Surgery Cases, 2017
Nasal polyps are inflammatory proliferative tumors arising from the mucosa of the nasal cavity and paranasal sinuses. Although many cases concerning nasal polyps have been reported, those involving external nasal deformities are rare. We report a case of

A global analysis of tandem 3'UTRs in eosinophilic chronic rhinosinusitis with nasal polyps. [PDF]

PLoS ONE, 2012
BackgroundAlternative polyadenylation (APA) is emerging as a widespread mechanism of gene regulation. The usage of APA sites allows a single gene to encode multiple mRNA transcripts with different 3'-untranslated region (3'UTR) lengths.

The evaluation of metallothionein expression in nasal polyps with respect to immune cell presence and activity

BMC Immunology, 2010
Background The expression of metallothionein (MT) is involved in acquiring resistance to immune-mediated apoptosis; it is also a negative regulator of the immune response.

Detection of helicobacter pylori in nasal polyps using rapid urease test and ELISA [PDF]

Iranian Journal of Otorhinolaryngology, 2009
Introduction: Nasal polyposis is an inflammatory condition of unknown etiology. Recently concerns regarding gastroesophageal reflux or helicobacter pylori as a possible pathologic cause of nasal polyps have been increasing.

Autoimmunity: A New Focus on Nasal Polyps

, 2023
Chronic rhinosinusitis with nasal polyps (CRSwNP) has long been considered a benign, chronic inflammatory, and hyperplastic disease. Recent studies have shown that autoimmune-related mechanisms are involved in the pathology of nasal polyps.

Leptin May Promote Eosinophilic CRSwNP Progression by Enhancing Eosinophil Chemotaxis and Angiogenesis Under a Type 2 Inflammatory Milieu

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyp (CRSwNP) is a heterogeneous Type 2 inflammatory disease characterized by enhanced eosinophilic infiltration. Both innate and adaptive immunity are involved in the onset and progression of CRSwNP.

Female‐Specific Risk of TAS2R Variants in Chronic Rhinosinusitis: A Hospital‐Based Cohort Study From the Taiwan Precision Medicine Initiative

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Bitter taste receptors (T2Rs) function in the innate immune defense of the sinonasal mucosa; however, the genetic association between the TAS2R gene family and chronic rhinosinusitis (CRS) remains understudied in Asian populations.

Periostin as a promising biological marker of early recurrence of polyposis rhinosinusitis after surgical treatment

Медицинский совет, 2021
Introduction. In spite of the numerous studies devoted to the issues of chronic rhinosinusitis with nasal polyps, the urgency of this problem remains due to the high incidence of the disease.

Tezepelumab in Chinese Patients With Severe Chronic Rhinosinusitis With Nasal Polyps: A Prespecified Subgroup Analysis of the Phase 3 WAYPOINT Trial

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) in Chinese patients often exhibits a mixed Type 1/2/3 inflammatory phenotype (63%), potentially impacting the efficacy of biologics targeting Type 2 inflammation. This prespecified subgroup analysis of WAYPOINT (NCT04851964) evaluated the efficacy and safety of tezepelumab in Chinese
