Chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) is an inflammatory sinonasal disorder characterized by eosinophilic inflammation and T-helper 2 skewing. Eosinophil accumulation in sinonasal mucosa comprises a major feature of CRSwNP. The study aimed to investigate the effect of the flavone wogonin in nasal polyposis by assessing its ability to induce eosinophil apoptosis in vitro and attenuate eosinophilic CRSwNP in mice. Double immunofluorescence, immunohistochemistry, flow cytometry, and immunoblotting were performed to evaluate hypoxia-inducible factor (HIF)-1α, survivin, and apoptotic markers in the human eosinophilic EoL-1 cell line or sinonasal tissues from patients with CRS with or without NPs...

The concept of chronic rhinosinusitis with or without polyps is founded on the structural and functional unicity of the pituitary mucosa and its united response to environmental aggression by allergens, viruses, bacteria, pollution, etc. The present review sets this concept against the evo-devo three-nose theory, in which nasal polyposis is distinguished as specific to the olfactory nose and in particular to the non-olfactory mucosa of the ethmoid, which is considered to be not a sinus but rather the skull-base bone harboring the olfactory mucosa...

OBJECTIVE: Eosinophilic asthma with chronic rhinosinusitis and/or nasal polyposis (EA-CRS/NP) is a subphenotype of adult-onset eosinophilic asthma. Blood eosinophil levels are shown to be highly elevated in patients with EA-CRS/NP and have potential for tissue infiltration. We aimed to demonstrate the clinical features of the patients who have a blood eosinophil level above 10% and have thorax computed tomography findings due to blood eosinophilia. METHODS: Patients who were followed up in our clinic between 2012 and 2017 were retrospectively evaluated...

Allergic conditions such as asthma and atopic dermatitis have a high prevalence but represent a heterogeneous group of diseases despite similar clinical presentation and underlying pathophysiology. A better understanding of the phenotypes and endotypes of these diseases has driven rapid development of biologic medications targeting many steps of the inflammatory pathways. Areas Covered: There are 2 major inflammatory pathways that drive allergic diseases: Type-2 (Th-2) inflammation and non-type 2 inflammation...

BACKGROUND: Spacers are inserted into the middle meatal space (MMS) following functional endoscopic sinus surgery (FESS) to prevent lateralization of the middle turbinate, scarring, and synechiae. Our objective was to determine if the incidence of postoperative synechiae, facial pain/discomfort, pain during spacer removal, scarring, and discharge differed between nasal cavities receiving Silastic or gloved-Merocel (GM) spacers following FESS. METHODS: A double-blind, randomized controlled trial (RCT) was conducted in adults requiring bilateral FESS for chronic rhinosinusitis (CRS) ± nasal polyposis...

Background: Chronic rhinosinusitis (CRS) is a heterogeneous, multifactorial inflammatory disease of the nasal and paranasal mucosa. It has not been possible to date to develop an internationally standardized, uniform classification for this disorder. A phenotype classification according to CRS with (CRSwNP) and without polyposis (CRSsNP) is usually made. However, a large number of studies have shown that there are also different endotypes of CRS within these phenotypes, with different pathophysiologies of chronic inflammation of the nasal mucosa...

BACKGROUND: Sinonasal disease is a common feature of cystic fibrosis (CF) and can cause significant morbidity in these patients. Our objective was to determine if CF individuals with concomitant nasal polyposis (NP) express a unique profile of inflammation and if so, whether these inflammatory cytokine mediators have predictive value in identifying these individuals for prompt management by an Otolaryngologist. METHODOLOGY: Nasal lavage samples and clinical outcomes of disease severity were obtained from thirty-eight pediatric CF individuals...

PURPOSE: Endotyping chronic rhinosinusitis with nasal polyps (CRSwNP) poses a challenge for rhinologists nowadays. Phenotyping CRSwNP proved inappropriate as an approach to their classification because of their common clinical features. Endotyping, being based on the pathogenic mechanism, provides a precise picture more appropriate for use in clinical practice. Patients' treatment and follow-up can thus be tailored to cope with the degree of aggressiveness of a specific CRSwNP endotype...

PURPOSE: The term aspirin-exacerbated respiratory disease (AERD) refers to a combination of asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), and acute respiratory tract reactions to nonsteroidal anti-inflammatory drugs. AERD has now been included among the CRSwNP endotypes, and is considered one of the most aggressive in terms of disease recurrence. Cortactin is a multi-domain protein with a part in several cellular mechanisms involving actin assembly and cytoskeleton arrangement...

Chronic rhinosinusitis is a heterogeneous group of inflammatory diseases with significant annual costs for the health care system. To date, there is no distinct signaling pathway known that explains the entire process from the beginning to tissue transformation. Due to the diversity of chronic rhinosinusitis, no uniform treatment has yet been developed. With a focus on chronic rhinosinusitis with nasal polyps (CRSwNP), molecular biologic gene expression studies have been performed to identify specific characteristics of nasal polyps that might allow the development of new therapeutic procedures...

Omalizumab, a monoclonal antibody against IgE, may be effective on nasal polyps, but its use is not currently authorized to treat that disease. We report the cases of three patients who were given omalizumab for asthma after undergoing nasal surgical polypectomy. Although such procedure is frequently followed by polyp recurrence, none of the three patients developed this complication, and in one subject the regression of initial polyp return was registered after starting omalizumab. Our data support the hypothesis that omalizumab may be useful to treat nasal polyposis...

Benzalkonium chloride (BAC) is a bactericidal preservative excipient commonly found in steroid nasal sprays used to treat allergic rhinitis and nasal polyposis. In rare cases, BAC can be responsible for type I and type IV hypersensitivity reactions that can manifest as rhinorrhea, which a clinician might misinterpret as a lack of response to nasal spray therapy rather than a complication of it. We report 3 cases of type IV hypersensitivity reactions in patients who were being treated with mometasone nasal spray...

Interleukin-17 producing T helper (Th17) and regulatory T cells (Treg) cells have been identified to play a critical role in atopic inflammation. However, conflicting reports on the role of Th17/Treg cells in allergic fungal rhinosinusitis (AFRS) patients of different ethnicities has mystified its pathogenesis. To better understand the pathophysiological mechanisms involved in AFRS, we conducted a prospective, analytical, case-control study involving 40 confirmed immunocompetent AFRS patients and 20 healthy controls...

The Fernand Widal syndrome is a set of associations between asthma, nasal polyposis and aspirin sensitivity. Selective cyclo-oxygenase 2 (COX 2) inhibitors are recognized as being a therapeutic alternative in cases needing analgesic or anti-inflammatory treatment. In a retrospective study, we have compiled data concerning oral provocation tests (OPT) undertaken with celecoxib, one of most the selective COX 2 inhibitors, in eight patients with the Fernand Widal syndrome. They were compared with twenty-seven control patients with sensitivity to aspirin or non-steroidal anti-inflammatories, manifesting as asthma, urticaria or rhino-conjunctivitis...

Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017...
