Abstract
PURPOSE The serum galactomannan test has been used for diagnosing acute invasive fungal sinusitis (AIFS), especially invasive Aspergillus. We aimed to assess the accuracy of the test to diagnose acute invasive Aspergillus sinusitis (AIAS). METHODS We searched all relevant articles published in PubMed, Embase, the Cochrane Library, and Web of Science databases up until September 14, 2020. The available data for serum galactomannan test to diagnose AIAS from selected studies were assessed. The diagnostic odds ratio (DOR), summary receiver operating characteristics (SROC), sensitivity, specificity, positive likelihood ratio (PLR), and negative likelihood ratio (NLR) were estimated. Additionally, we analysed four studies with a cut-off value of 0.5. RESULTS Five eligible articles were selected in this study. The total number of enrolled patients was 118, and 62 patients had confirmed AIAS. Among these 62 patients, the summary estimates of the serum galactomannan assay were as follows: DOR, 3.37 (95% confidence interval [CI]: 1.47-6.66); sensitivity, 0.63 (95% CI 0.50-0.74); specificity, 0.65 (95% CI 0.51-0.76); PLR, 1.83 (95% CI 1.21-2.74); NLR, 0.58 (95% CI 0.39-0.83). The SROC was 0.68. CONCLUSION In this current meta-analysis, the serum galactomannan test was classified as less accurate for purposes of diagnosing confirmed AIAS. These results suggest that the initial diagnosis of AIAS should not solely be dependent upon serum galactomannan test results. More studies of the test are needed in patients with AIAS to more accurately assess its diagnostic value.

Abstract
Objective - to study the species composition of microflora and its sensitivity in patients with odontogenic maxillary sinusitis. The study included 230 patients of both sexes aged 18 to 70 years, who were treated at the Moscow Regional Scientifics Research and Clinical Institute named after M. F. Vladimirsky with a diagnosis of Odontogenic maxillary sinusitis. Of these, there were 155 patients with odontogenic sinusitis, complicated by perforation of the maxillary sinus and the presence of an oro-antral fistula, and 75 patients with maxillary aspergillosis. All patients underwent microbiological examination of smears and flushes from the maxillary sinus cavity with the determination of the species composition and antibiotic sensitivity. In the majority of the patients with perforative forms of odontogenic maxillary sinusitis, coccal flora (streptococci and various species) was detected, in a smaller number compared to it - facultative and obligate anaerobes, pathogenic fungi (Candida). A comparative analysis of the microflora, depending on the duration of the maxillary sinus perforation, showed that the rhinogenic microorganisms (Moraxella spp.) were found only in intraoperative perforations (up to 20% of cases). The presence of obligate anaerobes (Fusobacterium spp. Bacteroides spp.) was typical for long-existing perforations. In patients with maxillary aspergillosis facultative and obligate anaerobes were found less frequently and in a smaller variety than in patients with perforative maxillary sinusitis. There were no cases of sinus contamination by pathogenic fungi of the genus Candida in this group. At the same time, rhinogenic microgranisms (Moraxella spp.) were detected with a higher frequency (up to 27.3%) in this group of patients.

An overview of possible pathogenesis mechanisms of Alternaria alternata in chronic rhino sinusitis and nasal polyposis. Microb Pathog 2021; 155:104905. [PMID: 33930423 DOI: 10.1016/j.micpath.2021.104905] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 04/16/2021] [Accepted: 04/16/2021] [Indexed: 01/23/2023]
Abstract
Chronic Rhinosinusitis (CRS) is a multifactorial disease, and different etiologies like metabolism and immunity disorders, bacterial superantigens, biofilms, and fungal allergens are known to develop this disease, especially the CRS with nasal polyps. Alternaria alternata (Alternaria) is one of the most prevalent airborne fungal species in the nasal discharge, which might have vigorous immunologic activities in nasal epithelial cells and play an essential role in the pathogenesis of CRS. Moreover, the interaction between this fungus and the innate and adaptive immune systems leads to the development of chronic inflammation. This inflammation may consequently instigate the CRS and nasal polyposis. The attenuation of surfactant protein synthesis or intracellular reserves and mucus hypersecretion could prevent the clearance of Alternaria from sinuses and may be correlated with colonization and re-infection of airborne fungi. Furthermore, higher expression of cathelicidin, thymic stromal lymphopoietin, toll-like receptors, and T helper 2-dominant immune responses can result in an IgE-mediated pathway activation and eosinophils degranulation. Moreover, higher local Alternaria-specific IgE was shown to be correlated with eosinophilic cationic proteins and might relate to nasal polyps. However, the role of genetic and environmental factors affecting CRS and nasal polyposis is not well studied. Likewise, further animal and clinical studies are required to better understand the role of Alternaria in CRS disease. The current article reviews the recent findings around the Alternaria-induced CRS and nasal polyposis.

Abstract
PURPOSE OF REVIEW Despite their high prevalence, the pathophysiology of allergic rhinitis (AR) and chronic rhinosinusitis (CRS) remains unclear. Recently, transient receptor potential (TRP) cation channels emerged as important players in type 2 upper airway inflammatory disorders. In this review, we aim to discuss known and yet to be explored roles of TRP channels in the pathophysiology of AR and CRS with nasal polyps. RECENT FINDINGS TRP channels participate in a plethora of cellular functions and are expressed on T cells, mast cells, respiratory epithelial cells, and sensory neurons of the upper airways. In chronic upper airway inflammation, TRP vanilloid 1 is mostly studied in relation to nasal hyperreactivity. Several other TRP channels such as TRP vanilloid 4, TRP ankyrin 1, TRP melastatin channels, and TRP canonical channels also have important functions, rendering them potential targets for therapy. The role of TRP channels in type 2 inflammatory upper airway diseases is steadily being uncovered and increasingly recognized. Modulation of TRP channels may offer therapeutic perspectives.

MEDICINA (KAUNAS, LITHUANIA) 2021; 57:282. [PMID: 33803540 PMCID: PMC8002897 DOI: 10.3390/medicina57030282] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 03/11/2021] [Accepted: 03/16/2021] [Indexed: 11/17/2022]
Abstract
Background and objectives: The aim of our study was to analyze the concentrations of inflammatory markers in the nasal tissue of patients with chronic rhinosinusitis with nasal polyps (CRSwNPs) and controls of different age groups, as well as to find associations between age, inflammation development, and NPs. Materials and methods: Patients were divided into two groups-patients with CRSwNPs and control subjects who had nasal surgery for another reason beside CRS. Our analysis was performed across three different age groups (18-30 years, 31-50 years, and 51 years and more). Tissue biopsies from the sinus cavity for all study participants were taken and frozen at -80 °C, until use. The concentrations of IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-10, IL-13, IL-21, and IL-22, were quantified using a magnetic bead-based multiplex assay. Results: In the group aged 18-30 years, the levels of inflammatory markers IL-1, IL-2, IL-5, and IL-22 were significantly higher in patients with CRSwNPs than the control subjects. Among patients aged 31-50 years, significantly higher concentrations of IL-2, IL-4, IL-5, and IL-22 were recorded in patients with CRSwNPs, as compared to the control subjects. In the oldest group (aged 51 years and more), patients with CRSwNPs had significantly higher concentrations of IL-2, IL-4, and IL-22, as compared to the control group. In the CRSwNP group, only the concentration of IL-21 was significantly higher among patients aged 31-50 years, as compared with those aged 51 years and older (p = 0.013). Conclusions: IL-2 and IL-22 levels were significantly higher in patients with CRSwNP than the control, across all age groups. Only the concentration of IL-21 was higher among patients with CRSwNP in the middle age group, as compared to the oldest group. IL-2, IL-4, and IL-22 levels correlated with the severity of CRSwNPs. Elevated concentrations of IL-2, IL-4, and IL-22 were determined in patients' groups with higher sinonasal outcome test (SNOT-22) scores, pointing to more severe clinical symptoms.

Abstract
Acute invasive fungal rhinosinusitis is a rare, although highly morbid, infection primarily affecting immunosuppressed individuals. The same population is at particularly high risk of complications and mortality in the setting of SARS-CoV-2 infection and coronavirus disease 2019 (COVID-19)-related acute respiratory distress syndrome. The authors present a case of acute invasive fungal rhino-orbital mucormycosis in a patient with COVID-19 and discuss the prevalence, diagnosis, and treatment of fungal coinfections in COVID-19. Prompt recognition, initiation of therapy, and consideration of the challenges of rapidly evolving COVID-19 therapy guidelines are important for improving patient survival.

Abstract
PURPOSE To present a case series treated by inferior meatal antrostomy as a prophylactic maneuver after the placement of zygomatic implants to decrease the risk of sinusitis. MATERIALS AND METHODS All patients undergoing zygomatic implant placement using the lower meatal antrostomy protocol between June 2011 and March 2019 at the Department of Oral and Maxillofacial Surgery, Universidad El Bosque, were included. Patients were evaluated after 12 months of the procedure using clinical and radiologic criteria described by Kuriyama and Reiskin. RESULTS Forty-eight patients were included, in whom 184 implants were placed. Complications were as follows: paresthesia (6.2%), orosinusal fistula (4.1%), skin infection (2.1%), and loss of the implant (1.6%). There were no cases of sinusitis. CONCLUSION This study provides evidence that the technique is effective and should be considered because of its simplicity. The inferior meatal antrostomy has been proven to be a simple, effective, and reliable technique to decrease the risk of sinusitis associated with the placement of zygomatic implants.

Abstract
Advances in our understanding of the immune system, with the recent discovery of a parallel set of innate T lymphocytes, the innate lymphocytes (ILCs), have led to a reassessment of the pathogenesis of allergic and eosinophilic airway disorders, including allergic rhinitis (AR), asthma, and chronic rhinosinusitis with nasal polyps. We review current understanding of both elements of type-2 inflammatory responses and their relative influence in these common conditions and consider possible impacts of this on treatment selection.

Abstract
Individual anatomical features of the paranasal sinuses and dentoalveolar system, the complexity of physiological and pathophysiological processes in this area, and the absence of actual standards of the norm and typical pathologies lead to the fact that differential diagnosis and assessment of the severity of the course of odontogenic sinusitis significantly depend on the measurement methods of significant indicators and have significant variability. Therefore, an urgent task is to expand the diagnostic capabilities of existing research methods, study the significance of the measured indicators, and substantiate the expediency of their use in the diagnosis of specific pathologies in an automated mode. Methods of digital filtering, image segmentation and analysis, fluid dynamics, and statistical and discriminant analysis were used. Preliminary differential diagnosis of odontogenic sinusitis can be performed by densitemetric analysis of tomographic images of the maxillary sinuses, performed using frontal multiplanar reconstructions according to a given algorithm. The very manifestation of the characteristic changes in the densitography of the maxillary sinus allows for the initiation of certain pathological processes and permits the development of the effectiveness of the diagnosis of the pathology of the sinus sinuses, which can be realized automatically in real life.

Abstract
Chronic rhinosinusitis(CRS) is a highly heterogeneous chronic inflammatory disease of the sinus mucosa. Despite extensive research, the etiology of CRS remains unclear. Studies of upper respiratory tract microbiology have found that microorganisms may be the influencing factors of CRS, and bacteria may be the potential pathogenic factors of CRS. The study of the role of bacterial infection in the initiation, development and maintenance of CRS has become a hot spot in the pathogenesis of CRS. In this review, we describes the research progress of the relationship between bacteria infection and CRS.

Abstract
Objective:The aim of this stusy is to study the effect of endoscopic surgery quality on the recurrence of nasal polyps. Methods:A total of 32 patients(64 sides) with recurrent nasal polyps were collected from December 2016 to June 2018, all of which were bilateral type Ⅱ diffuse nasal polyps in stage 3. According to the post-operative pathological results, patients were divided into eosinophilic nasal polyps group(EOS) and non-eosinophilic nasal polyps group(NEOS). All patients underwent sinus CT scan and three-dimensional reconstruction, combined with the sinus CT image performance and intraoperative findings, the quality of the patients' previous endoscopic sinus surgery was analyzed, and the CT L-M scores of sinuses before and after reoperation were compared between the two groups. Endoscopic L-K score, nasal symptoms VAS score, quality of life Snot-20 score. Results:Among 32 patients with recurrent nasal polyps, 17 cases (53.1%) of EOS nasal polyps were confirmed pathologically after surgery, and 15 cases (46.9%) of NEOS nasal polyps were confirmed. After the previous operation, the patient still has 60 sides(93.8%) of ethmoidal cells or ethmoidal septum, 56 sides(87.5%) of bone hyperplasia, 50 sides(78.1%) of bones in frontal recess air-cell or bone air-cell, and nasal cavity adhesion there were 10 sides(15.6%), residual uncinate process 8(12.5%), improper treatment of maxillary sinus ostia or atresia were 6(9.4%), sphenoid sinus not open or atresia were 8(12.5%), nasal septal deviation untreated were 4 cases(12.5%), 1 case(3.1%) had recurrence without ethmoidal cells and residual bone interval. Patients both in the EOS group or the NEOS group were followed up with L-M score, L-K score, VAS score, and Snot-20 score after surgery, the result were significantly improved compared with the preoperative results. After follow-up of 1.5-3 years, 25 cases of polyps were completely controlled and 7 cases were partially controlled. Among them, 2 cases of EOS nasal polyps and asthma patients still had some polypoid changes in local mucosa one year after operation and was currently under medication control. Conclusion:Although the recurrence of nasal polyps is closely related to its intrinsic type, the technique of endoscopic surgery is also an important factor affecting the recurrence of nasal polyps. For patients with bilateral symmetric diffuse nasal polyps, high-quality sinus surgery of first time combined with standardized follow-up can reduce the recurrence rate of nasal polyps and prolong the relapse time.

Abstract
Isolated sphenoid osteomas are very rare even in adults. There are extremely few publications on pediatric cases of sphenoid osteomas. This paper presents a case of isolated sphenoid osteoma combined with suppurative sphenoiditis in a 15-year-old patient. The child presented with persistent headache resistant to medical treatment. Endoscopic sphenotomy allowed both to remove osteoma and to relieve the symptoms of sinusitis. The presented case can be considered as the third detailed description of the sphenoid osteoma in children and the first demonstration of the effectiveness of the endoscopic approach for its removal.

Abstract
ABSTRACT An 8-year-old male presented to the pediatric emergency department with subjective fever, blurry vision, and left eye pain. On physical examination, there was mild left lower lid erythema and a subtle left eye elevation deficit. Computed tomography demonstrated preseptal soft tissue swelling without orbital involvement; however, there was varying amounts of paranasal sinus opacification. Despite the negative scan, a diagnosis of orbital cellulitis associated with sinusitis was made and treatment with intravenous antibiotics was initiated. A magnetic resonance imaging performed subsequently revealed orbital fat stranding and inferior rectus enlargement and enhancement near the orbital apex, indicating the presence of orbital cellulitis. This case demonstrates the utility of magnetic resonance imaging when initial computed tomography imaging is negative in patients with concern for orbital cellulitis.

Abstract
OBJECTIVE Numerous meta-analyses have revealed the association between gastro-oesophageal reflux disease (GORD) and a range of diseases; however, the certainty of the evidence remains unclear. This study aimed to summarise and assess the certainty of evidence derived from meta-analyses. METHODS Embase, PubMed, Web of Science, Cochrane Databases of Systematic Reviews, CNKI and Wangfang databases from their inception to 22 February 2020 were queried for systematic reviews and meta-analyses on the association between GORD and various diseases. The methodological quality of the included studies was assessed using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), and evidence certainty was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Statistical analysis was conducted using Stata V.15. RESULTS Ten publications with associations between GORD and different types of diseases were included. There was high heterogeneity (I2 >75%) among seven independent meta-analyses. Evidence for publication bias in two independent meta-analyses was also observed. According to the AMSTAR 2 approach, the methodological quality was high for 20% of meta-analyses, moderate for 10%, low for 40% and critically low for 30%. Based on GRADE approach, the certainty of evidence was high for the association between GORD and higher risk of chronic obstructive pulmonary disease (COPD) exacerbation (OR 5.37; 95% CI 2.71 to 10.64) and higher prevalence of oesophageal adenocarcinoma (OR 4.57; 95% CI 3.89 to 5.36), and it was moderate for the association between GORD and higher chronic rhinosinusitis prevalence (OR 2.16; 95% CI 1.37 to 3.48). CONCLUSION The association between GORD and a range of diseases was extensively studied, and our findings revealed a high certainty of evidence of the association between GORD and an increased risk of COPD exacerbation as well as increased prevalence of oesophageal adenocarcinoma. Further investigations using systematic reviews and meta-analyses of high methodological quality that include prospective large cohort studies and adjusted confounders are warranted.

Abstract
PURPOSE Distinguishing the prodromal nasal polyposis of eosinophilic granulomatosis with polyangiitis (EGPA) from chronic rhinosinusitis with nasal polyps (CRSwNP) is a challenge for rhinologists and rheumatologists. It has recently been reported that angiogenesis and CD105 expressed on vascular endothelial cells could have a role in the pathogenesis and development of nasal polyps. This exploratory study examined the structured histopathology of nasal polyps in patients with EGPA and CRSwNP, comparing CD105 expression in their nasal tissue with that of a control group with no chronic sinonasal inflammation. METHODS A structured histopathological study was performed on surgical specimens of nasal tissue from 32 adults (13 with EGPA, 14 with CRSwNP, 5 controls), considering CD105 as a marker to determine microvessel density (MVD). RESULTS The mean eosinophil count was higher in EGPA patients with tissue inflammation (p = .002), and in CRSwNP patients with sub-epithelial edema (p = .009). Neutrophil infiltration was significantly associated with severe tissue inflammation in EGPA patients (p = .04), but with the absence of fibrosis in CRSwNP patients (p = .04). In the EGPA group, CD105-MVD correlated with tissue eosinophil count (p = .05). Mean CD105-MVD was significantly higher in EGPA patients with mucosal ulceration (p = .004). In the CRSwNP group, a CD105-MVD correlated positively and significantly with tissue eosinophil count (p = .01). CONCLUSION Alongside the known abundance of eosinophils, other cells might contribute to inflammatory processes. Neutrophils may amplify inflammation, eosinophil recruitment and tissue damage. CD105 expression in CRSwNP and EGPA nasal polyps supports the hypothesized involvement of angiogenesis in the pathogenesis and development of nasal polyps.

Abstract
PURPOSE The role of the microbiome in the paranasal sinuses and its contribution to sinus mucosal health and disease remains poorly understood. Consequently, we examined the nasal microbiome of chronic rhinosinusitis patients with polyps (CRSwNP), chronic sinusitis without nasal polyps (CRSsNP) and a control population, associated with IL-5 of nasal polyp tissues and postoperative follow-up of CRSwNP patients, in search of nasal microbial community characteristics related to pathogenesis and prognosis of CRSwNP, providing a new perspective for further understanding of the disease. METHODS The middle meatus secretions of 77 CRSwNP, 36 CRSsNP and 34 non-CRS subjects were collected. The bacterial microbiome composition was detected using high-throughput sequencing technology based on 16S rRNA, and the differences in the nasal microbial diversity among the three groups were compared. At the same time, nasal polyp tissues were collected to detect the expression of IL-5 and analyse its relationship with the structural characteristics of nasal microbial colonies. Postoperative follow-up of patients with CRSwNP was conducted for 1 year to record the recurrence of nasal polyps and analyse the correlation between the recurrence of nasal polyps and IL-5 as well as the characteristics of nasal microbial diversity. RESULTS The results showed that the average Sobs index (579.31) of the non-CRS group was significantly higher than that of the CRSwNP group (387.31, P = 0.03). PCoA analysis showed that the microbial distribution in the three groups was mostly similar, with only a few unique to each group. At the phylum level, Actinobacteria and Chlamydia in the non-CRS group were significantly higher than those in the CRSwNP and CRSsNP groups. At the genus level, Corynebacterium and Dolosigranulum in the non-CRS group were significantly higher than those in the CRSwNP and CRSsNP groups. Twenty-five CRSwNP patients had nasal polyps that were IL-5 positive, accounting for 32.47%, and the relative abundance of Enterobacter was 6.37% ± 5.92%, which was significantly higher than 0.58% ± 0.11% in the IL-5 negative group. No significant difference was found after correction (p = 0.026, FDR p > 0.05). One year after surgery, 77 patients with CRSwNP who underwent surgery were successfully followed up, and 12 patients with CRSwNP relapsed, with a recurrence rate of 15.6%. Total nasal symptom scores (TNSS) were significantly higher in the recurrent group than in the nonrecurrent group (P = 0.000). No differences in microbial diversity were found between the CRSwNP populations in the recurrent group and the nonrecurrent group at both the phylum and genus levels. For the nonrecurrent CRSwNP group, the relative abundance of Actinobacteria (PDR P = 0.012) and Corynebacterium (PDR P = 0.003) was higher than that before surgery, and the relative abundance of Bacteroidetes (PDR P = 0.040) was lower than that before surgery. However, for the recurrence CRSwNP group, there was no significant difference in the nasal microbiome between postoperation and preoperation. CONCLUSION In conclusion, microbial dysbiosis in the nasal cavity is associated with the pathogenesis of CRSwNP. In Southwest China, the inflammatory pattern of nasal polyps is not dominated by eosinophilic infiltration of Th2-type inflammation. The recurrence of nasal polyps after ESS may be potentially related to the decrease in protective bacteria and the increase in pathogenic bacteria, and the improvement of postoperative bacterial disorder is correlated with the nonrecurrence of CRSwNP.

Abstract
Human microbiome studies remain focused on bacteria, as they comprise the dominant component of the microbiota. Recent advances in sequencing technology and optimization of amplicon sequencing protocols have allowed the description of other members of the microbiome, including eukaryotes (fungi) and, most recently, archaea. There are no known human-associated archaeal pathogens. Their diversity and contribution to health and chronic respiratory diseases, such as chronic rhinosinusitis (CRS), are unknown. Patients with CRS suffer from long-term sinus infections, and while the microbiota is hypothesized to play a role in its pathogenesis, the exact mechanism is poorly understood. In this cross-sectional study, we applied a recently optimized protocol to describe the prevalence, diversity and abundance of archaea in swab samples from the middle meatus of 60 individuals with and without CRS. A nested PCR approach was used to amplify the archaeal 16S rRNA gene for sequencing, and bacterial and archaeal load (also based on 16S rRNA genes) were estimated using Droplet Digital™ PCR (ddPCR). A total of 16 archaeal amplicon sequence variants (ASVs) from the phyla Euryarchaeota and Thaumarchaeota were identified. Archaeal ASVs were detected in 7/60 individuals, independent of disease state, whereas bacterial ASVs were detected in 60/60. Bacteria were also significantly more abundant than archaea. The ddPCR method was more sensitive than amplicon sequencing at detecting archaeal DNA in samples. Phylogenetic trees were constructed to visualize the evolutionary relationships between archaeal ASVs, isolates and clones. ASVs were placed into phylogenetic clades containing an apparent paucity of human-associated reference sequences, revealing how little studied the human archaeome is. This is the largest study to date to examine the human respiratory-associated archaeome, and provides the first insights into the prevalence, diversity and abundance of archaea in the human sinuses.

Abstract
Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disease with an as-yet-undefined etiology. In contrast to the phenotypic classification of chronic rhinosinusitis, endotype classification is based on its underlying pathophysiological mechanisms. Endotypes of CRS can provide information on the risk of disease progression, recurrence and comorbidities, as well as identify appropriate therapeutic targets to further guide the precise treatment of CRS. This article classifies the endotypes of CRS based on cytokines, cell composition, IgE and CysLT, and outlines the clinical application of several targeted therapeutic biologics.

Abstract
PURPOSE The purpose of this study was to describe the microbiology of recurrent acute exacerbations of chronic rhinosinusitis over time. METHODS Retrospective review of patients with recurrent acute exacerbations of chronic rhinosinusitis who underwent endoscopic-guided cultures during acute exacerbations of chronic rhinosinusitis. RESULTS 386 cultures were obtained from 112 patients during recurrent acute exacerbations of CRS. A change of bacterial isolates during the course of recurrent exacerbations was observed in 68% (76/112) of patients, necessitating a change of treatment in 40% (45/112). The main risk factor for the subsequent change in cultures was polymicrobial growth. Sinus surgery was not associated with subsequent change in cultured isolates. Resistant strains developed in 11.6% (13/112) of patients, of whom those with abnormal mucociliary clearance being at the highest risk. CONCLUSION Repeated middle meatal cultures should be considered in patients with recurrent exacerbations of CRS, particularly in cases not responding to standard therapy.

Abstract
PURPOSE Nasal polyp formation is a common sequela of prolonged chronic rhinosinusitis, but the mechanism underlying this disease state is still controversial. We compared the expressions of Cl- channels/transporters in nasal polyps with those in inferior turbinates to explore whether a deficiency in Cl- transport may participate in the pathophysiology of nasal polyp formation as in patients with cystic fibrosis. METHODS Nasal polyps and inferior turbinates were collected from 12 chronic rhinosinusitis patients with hypertrophic rhinitis and/or nasal polyps. Expressions of cystic fibrosis transmembrane conductance regulator (CFTR), pendrin, Na+-K+-2Cl- cotransporter 1 (NKCC1), SLC26A3, TMEM16A and anion exchanger 2 (AE2) were examined by fluorescence immunohistochemistry using Alexa Fluor 488. RESULTS CFTR was weakly expressed on the epithelial surface of the turbinate mucosa whereas the nasal polyps showed almost no fluorescence. Pendrin was mainly expressed on the epithelial surface in both tissues. The fluorescence was moderate in the nasal polyps and strong in the turbinate mucosa. For NKCC1, moderate fluorescence was observed throughout the entire epithelial layer of the nasal polyps, but the turbinate mucosa exhibited almost no fluorescence. On the other hand, no fluorescence for SLC26A3, TMEM16A or AE2 was seen in either tissue. CONCLUSION These results suggest that CFTR, pendrin and NKCC1 may participate in the pathogenesis of nasal mucosal edema and play roles in the mechanism of nasal polyp formation.

Abstract
This study offers a novel description of the sinonasal microbiome, through an unsupervised machine learning approach combining dimensionality reduction and clustering. We apply our method to the International Sinonasal Microbiome Study (ISMS) dataset of 410 sinus swab samples. We propose three main sinonasal "microbiotypes" or "states": the first is Corynebacterium-dominated, the second is Staphylococcus-dominated, and the third dominated by the other core genera of the sinonasal microbiome (Streptococcus, Haemophilus, Moraxella, and Pseudomonas). The prevalence of the three microbiotypes studied did not differ between healthy and diseased sinuses, but differences in their distribution were evident based on geography. We also describe a potential reciprocal relationship between Corynebacterium species and Staphylococcus aureus, suggesting that a certain microbial equilibrium between various players is reached in the sinuses. We validate our approach by applying it to a separate 16S rRNA gene sequence dataset of 97 sinus swabs from a different patient cohort. Sinonasal microbiotyping may prove useful in reducing the complexity of describing sinonasal microbiota. It may drive future studies aimed at modeling microbial interactions in the sinuses and in doing so may facilitate the development of a tailored patient-specific approach to the treatment of sinus disease in the future.

Abstract
Objective:To analyze the correlation between the modified nasal endoscopic score and ELR value and the subtype of chronic sinusitis with nasal polyps. Method:The clinical data of 119 patients of chronic sinusitis with nasal polyps were retrospectively analyzed. According to the postoperative pathological results, they were divided into two groups: eosinophilic chronic sinusitis with nasal polyps(eCRSwNP) and non-eosinophilic chronic sinusitis with nasal polyps(neCRSwNP). All patients underwent modified nasal endoscopic examination scores, according to clinical features and anatomical features into the part of the middle nasal meatus and the part of olfactory fissure, and the scores were calculated in two areas respectively; History of asthma, allergic rhinitis and the percentage of eosinophils(EO%), the absolute value of eosinophils(EO#), the absolute neutrophil(N), the absolute lymphocyte(R), the total IgE were recorded at the same time. Calculate the NLR value and ELR value. This study used SPSS 19.0 for statistical analysis of relevant data. Result:According to the modified nasal endoscopic scoring criteria, the eCRSwNP group had significantly higher olfactory fissure area scores while middle nasal meatus area scores were significantly lower than the neCRSwNP group; ELR value, EO% and EO# were significantly higher in the eCRSwNP group than in the control group, while NLR value and N value were higher in the neCRSwNP group(P<0.05); There was no significant difference in age, gender, R value and total IgE between the two groups. Compared with EO#, the ELR value was more stability and sensitivity. Therefore, the olfactory fissure area polyps and ELR value are more significant for pre-diagnosis. Conclusion:The modified nasal endoscopic score and ELR value are more correlated with the subtype of CRSwNP. Higher ELR value ,lower NLR value, and association with allergic rhinitis, asthma can be used as prediagnostic indicators for eCRSwNP before invasive pathological results and CT examination.
