Resveratrol (RSV) has been shown to effectively suppress chronic rhinosinusitis with nasal polyps in a mouse model; however, when locally administered to the sinonasal cavity, bolus RSV is limited by low drug bioavailability owing to its low aqueous solubility and relatively rapid clearance from the administration site. To address this limitation, we propose mucoadhesive nanostructured microparticles (PLGA/PEG NM) as a potential carrier for the sinonasal delivery of RSV. In this study, PLGA/PEG NM released RSV in a sustained manner...

The signaling pathways that sustain the disease process of chronic rhinosinusitis with nasal polyps (CRSwNP) remain poorly understood. We sought to determine the expression levels of Wnt signaling genes in CRSwNP, and to study the role of the Wnt pathway in inflammation and epithelial remodeling in the nasal mucosa. Microarrays and RT-qPCR comparing gene expression in matched nasal polyps (NP) and inferior turbinates (IT) revealed that WNT2B, WNT3A, WNT4, WNT7A, WNT7B and FZD2 were upregulated, and FZD1, LRP5, LRP6 and WIF1 downregulated in NPs...

INTRODUCTION: Inflammatory diseases of the maxillary sinus favour the thickening of the sinus mucosa. Therefore, it might be possible to establish a radiological, pathological threshold of mucosal thickening. Furthermore, there is an association between common anatomic variants of the nose and maxillary mucosal thickening. AIM: To define the pathological thickening of maxillary sinus mucosa and its association with the presence of common anatomic variants (concha bullosa, Haller's cell and accessory maxillary ostium)...

Rhinosinusitis, is defined as an inflammation of the paranasal and nasal sinus mucosae. Chronic rhinosinusitis (CRS)is a common problem in the pediatric age group and the diagnosis and treatment are challenging due to the chronicity and similarity of symptoms with allergic rhinitis and adenoid hypertrophy. Although it is less common than acute rhinosinusitis, CRS is becoming more frequent and significantly affects the quality of life in children and can substantially impair daily function. CRS is characterized by sinus symptoms lasting more than 3 months despite medical therapy...

REVIEW
Nicole Rotter
Therapeutic decisions in otorhinolaryngology are based on clinical experience, surgical skills, and scientific evidence. Recently, evidence-based therapies have gained increased attention and importance due to their potential to improve the individual patient's treatment and their potential at the same time to reduce treatment costs. In clinical practice, it is almost impossible to stay ahead of the increasing mass of literature and on the other hand critically assess the presented data. A solid scientific and statistical knowledge as well as a significant amount of spare time are required to detect systematic bias and other errors in study designs, also with respect to assessing whether or not a study should be part of an individual therapeutic decision...

Our goal in treating chronic rhinosinusitis (CRS) is to reduce sinonasal symptoms and improve quality of life (QoL). In patients with CRS, sinonasal symptoms have a significant impact on QoL. Various validated measures exist to quantify QoL such as the 22-item Sinonasal Outcomes Test (SNOT- 22) and MSNOT-20 Young Persons Questionnaire (MSYPQ) specific to CRS, while others measure general QoL, such as the EuroQol 5-Dimensional general health-related QoL survey (EQ5D).

INTRODUCTION: Foreign bodies in the upper aerodigestive tract often get lost following inappropriate attempts at removal. Children may present late with localized infection, posing a challenge to the otolaryngologists in a referral set-up in diagnosing and retrieving such foreign bodies. CASE REPORT: A two-year-old boy presented with refractory purulent rhinorrhea and intermittent low-grade fever. The symptoms suggested rhinosinusitis; however, following a high index of suspicion, he was referred for further evaluation, with the possibility of any hidden foreign object in the upper aerodigestive tract...

Balloon dilatation of sinus ostia (sinuplasty) was introduced in 2005 as a treatment for Chronic Rhinosinusitis (CRS).(1) It has been described as a 'transition space' tool for the ethmoidal infundibulum and frontal recess.(1) It can been used as a lone procedure or in combination with functional endoscopic sinus surgery (FESS) as a "hybrid" technique. Balloon sinuplasty applies the Seldinger technique to cannulate and dilate stenosed or occluded sinus ostia re-establishing drainage pathways and ventilation...

Damage to the mucociliary clearance system is a typical change in the pathogenesis in chronic rhinosinusitis. However, the mechanisms underlying cilia loss remain unclear. WDPCP is a key protein essential for ciliogenesis, and is also an effector of the planar cell polarity signaling system. In this study, we sought to determine the role of WDPCP in cilia loss in patients with chronic rhinosinusitis. We demonstrated the expression of WDPCP in human sinonasal epithelium from patients with chronic rhinosinusitis and control subjects...

BACKGROUND: B cells play many roles in health and disease. However, little is known about the mechanisms that drive B cell responses in the airways, especially in humans. Chronic rhinosinusitis (CRS) is an inflammatory disease of the upper airways that affects 10% of Europeans and Americans. A subset of CRS patients develop nasal polyps (NP), which are characterized by type 2 inflammation, eosinophils and group 2 innate lymphoid cells (ILC2). We have reported that NP contain elevated levels of B cells and antibodies, making NP an ideal system for studying B cells in the airways...
