Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is common in individuals with cystic fibrosis (CF) and is marked by chronic inflammation and episodes of infection that negatively impact quality of life. Several studies have shown that elexacaftor-tezacaftor-ivacaftor (ETI) improves symptoms and examination findings in CF-CRS. The current study determines the effect of ETI on the sinonasal microbiota in CF. METHODS Sinonasal samples were collected under endoscopic visualization before and after starting ETI. Samples were subjected to 16S amplicon sequencing and sequences were processed with the QIIME2 pipeline with subsequent analysis using the vegan R-package. RESULTS Twenty-nine individual baseline samples and 23 sample pairs pre-/post-ETI were available. At baseline, the cohort had samples dominated by Staphylococcus, and alpha diversity was lower than that of a published reference set of individuals without sinonasal disease. Individuals with prior sinus surgery had lower alpha diversity as measured by Shannon Index, Observed Richness, and Faith's phylogenetic diversity Index. Beta diversity differed between individuals with and without allergic rhinitis, with higher Staphylococcus abundance in those with allergic rhinitis. No change in alpha or beta diversity was seen after a median of 9 months on ETI. With ETI, the Pseudomonas genus and the genus containing Burkholderia decreased in samples containing these taxa at baseline. Pseudomonas abundance decreased with treatment as measured by qPCR. Core sinonasal microbiome members Staphylococcus, Corynebacterium, and Streptococcus were unchanged, while Moraxella increased with ETI. CONCLUSIONS Treatment with ETI leads to a reduction in Pseudomonas abundance within the sinonasal microbiome of individuals with Pseudomonas at baseline.

Abstract
OBJECTIVE Fungal balls (FB) are the main form of non-invasive fungal rhinosinusitis found in immunocompetent hosts. Bacterial coinfection affects clinical symptoms. We investigated the sinonasal microbiome and inflammatory profiles in FB and chronic rhinosinusitis (CRS) patients. METHODS Thirty-three participants were prospectively recruited. Nasal swab samples and sinonasal tissues were collected from controls, and FB and CRS patients. DNA extraction and microbiome analysis using V3-V4 region 16S rRNA sequencing were performed. Inflammatory cytokine levels in the sinonasal tissues, blood eosinophil counts, and serum total IgE were measured. RESULTS No significant differences were observed in species richness or evenness measures. The phylogenetic tree demonstrated that the FB samples were different from the controls. The sinus bacteria composition differed among the groups. At the phylum level, Firmicutes in FB were significantly depleted compared with those in CRS, while Proteobacteria were more enriched in FB than that in controls and CRS. At the genus level, in FB, Staphylococcus and Corynebacterium were significantly decreased compared to those in the controls. The prevalence of Haemophilus was the highest in FB. Blood eosinophil counts and IL-5 and periostin levels in the sinonasal tissue of the FB group were significantly lower than those in the CRS group. CONCLUSIONS FB patients had different microbiome compositions and fewer type 2 inflammatory profiles than CRS patients did. However, whether these findings cause FB or result from bacterial and/or fungal infection remains unclear. Further studies are needed to reveal how these differences occur and affect the development of FB and clinical symptoms.

Abstract
Aspergillus flavus is a commonly encountered pathogen responsible for fungal rhinosinusitis (FRS) in arid regions. The species is known to produce aflatoxins, posing a significant risk to human health. This study aimed to investigate the aflatoxin profiles of A. flavus isolates causing FRS in Sudan. A total of 93 clinical and 34 environmental A. flavus isolates were studied. Aflatoxin profiles were evaluated by phenotypic (thin-layer and high-performance chromatography) and genotypic methods at various temperatures and substrates. Gene expression of aflD and aflR was also analyzed. A total of 42/93 (45%) isolates were positive for aflatoxin B1 and AFB2 by HPLC. When the incubation temperature changed from 28°C to 36°C, the number of positive isolates decreased to 41% (38/93). Genetic analysis revealed that 85% (79/93) of clinical isolates possessed all seven aflatoxin biosynthesis-associated genes, while 27% (14/51) of non-producing isolates lacked specific genes (aflD/aflR/aflS). Mutations were observed in aflS and aflR genes across both aflatoxin-producers and non-producers. Gene expression of aflD and aflR showed the highest expression between the 4th and 6th days of incubation on the Sabouraud medium and on the 9th day of incubation on the RPMI (Roswell Park Memorial Institute) medium. Aspergillus flavus clinical isolates demonstrated aflatoxigenic capabilities, influenced by incubation temperature and substrate. Dynamic aflD and aflR gene expression patterns over time enriched our understanding of aflatoxin production regulation. The overall findings underscored the health risks of Sudanese patients infected by this species, emphasizing the importance of monitoring aflatoxin exposure.

Abstract
Chronic rhinosinusitis (CRS) is a multifactorial infection of the nasal cavity and sinuses. In this study, nasal swabs from control donors (N = 128) and patients with CRS (N = 246) were analysed. Culture methods and metagenomics revealed no obvious differences in the composition of the bacterial communities between the two groups. However, at the functional level, several metabolic pathways were significantly enriched in the CRS group compared to the control group. Pathways such as carbohydrate transport metabolism, ATP synthesis, cofactors and vitamins, photosynthesis and transcription were highly enriched in CRS. In contrast, pathways related to lipid metabolism were more representative in the control microbiome. As S. aureus is one of the main species found in the nasal cavity, staphylococcal isolates from control and CRS samples were analysed by microarray and functional assays. Although no significant genetic differences were detected by microarray, S. aureus from CRS induced less cytotoxicity to lung cells and lower rates of glycolysis in host cells than control isolates. These results suggest the differential modulation of staphylococcal virulence by the environment created by other microorganisms and their interactions with host cells in control and CRS samples. These changes were reflected in the differential expression of cytokines and in the expression of Agr, the most important quorum-sensing regulator of virulence in S. aureus. In addition, the CRS isolates remained stable in their cytotoxicity, whereas the cytotoxic activity of S. aureus isolated from control subjects decreased over time during in vitro passage. These results suggest that host factors influence the virulence of S. aureus and promote its adaptation to the nasal environment during CRS.

Abstract
BACKGROUND A multimodal approach for diagnostic tests under anesthesia is required to diagnose nasal cavity pathology (NP) reliably in dogs. Blood test results may provide clues to the suspected NP. METHODS This prospective blinded study assessed 72 dogs with chronic nasal discharge due to NPs, and 10 healthy dogs as the control group (CG). NPs were diagnosed using whole-body computed tomography (CT), upper airway endoscopy, examination of nasal mucosal swabs by bacterial and fungal culture, and histopathological examination of nasal mucosa biopsies. The exclusion criteria were the presence of any additional diseases or corticosteroid pre-treatment. In consideration of these exclusion criteria, 55 dogs entered the study. Dogs were classified into benign (benign tumors, idiopathic rhinitis (IR), and others) and malignant (carcinomas and sarcomas) NP groups. Blood count and blood chemistry tests were performed. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and albumin-to-globulin ratio (AGR) were calculated and compared. RESULTS 25 dogs with malignant NP (13 and 12 with carcinomas and sarcomas, respectively) and 30 dogs with benign NP (seven with benign tumors,13 with IR, and 10 others) were included. In general, in dogs with NP there were only slight abnormalities in complete blood count. However, PLR was significantly higher in dogs with malignant NP (carcinoma and sarcoma) than in those with benign NP and in the CG. Compared with the CG, the NLR was significantly increased in all dogs with NP, and the AGR was mild but significantly lower, except in dogs with sarcomas and benign tumors. CONCLUSIONS In dogs with nasal disease alone, there are usually no marked abnormalities in blood count. However, while mildly increased NLR and decreased AGR can be observed in almost all NPs, an increased PLR may indicate a malignant NP and can be used as an additional screening tool in dogs with nasal discharge due to nasal cavity pathology.

Abstract
Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the sinus mucosa, and the pathogenesis of CRS has not been fully elucidated, and the impact of dysbiosis of the microbiome in the nasal cavity and even in the gut on the pathogenesis of CRS remains controversial. Next-generation sequencing technology, a culture-independent high-throughput sequencing method, contributes to a comprehensive understanding of the CRS microbiome. This article reviews the progress of research on the relevance of bacteria and other microorganisms to CRS and the microbial characteristics of the sinus and intestinal tract of patients with CRS, introduces next-generation sequencing technologies for the study of the CRS microbiome, and discusses the therapeutic prospects of CRS and the possibility of probiotic therapy.

Abstract
PURPOSE Worldwide, the incidence of chronic fungal rhinosinusitis (CFRS) has increased. Although ageing leads to weakening of the immune system, which increases susceptibility to CFRS, the CFRS characteristics in geriatric patients are unclear. Therefore, we comparatively analysed the clinical characteristics of CFRS in geriatric and non-geriatric patients. METHODS This retrospective analysis compared the demographics, rhinologic symptoms, multiple allergen simultaneous tests, olfactory function tests, paranasal sinus computed tomography findings, and outcomes of 131 patients with CFRS who underwent functional endoscopic sinus surgery and 131 enrolled patients were divided in geriatric (> 65 years) and non-geriatric (≤ 65 years) groups. RESULTS Among the geriatric and non-geriatric participants (n = 65, 49.6% and n = 66, 50.4%, respectively), hypertension and diabetes mellitus were more common in the geriatric group. Demographics, including symptoms, showed no significant intergroup differences. Normosmia and hyposmia were significantly less prevalent, whereas phantosmia and parosmia were more prevalent in the geriatric group than in the non-geriatric group (p = 0.03 and p = 0.01, respectively). Sphenoidal sinus involvement was significantly higher in geriatric patients than in non-geriatric patients (p = 0.02). CONCLUSION Based on greater sphenoidal sinus involvement, a deeper anatomical area is more vulnerable to fungal infection in the geriatric group than in the non-geriatric group. Increasing clinicians' awareness of CFRS in geriatric patients with olfactory dysfunction, including phantosmia and parosmia, is important for early intervention.

Abstract
OBJECTIVE Some previous studies have shown an increased prevalence of allergic fungal rhinosinusitis (AFRS) among young, black patients with poor access to health care; however, results have been mixed. The purpose of this study was to investigate the relationship between social determinants of health and AFRS. DATA SOURCES PubMed, Scopus, CINAHL. REVIEW METHODS A systematic review was performed searching for articles published from date of inception to September 29, 2022. English language articles describing the relationship between social determinants of health (i.e., race, insurance status) and AFRS as compared to chronic rhinosinusitis (CRS) were selected for inclusion. A Meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. RESULTS A total of 21 articles with 1605 patients were selected for inclusion. The proportion of black patients among AFRS, chronic rhinosinusitis with nasal polyps (CRSwNP), and chronic rhinosinusitis without nasal polyps (CRSsNP) groups was 58.0% [45.3%-70.1%], 23.8% [14.1%-35.2%], and 13.0% [5.1%-24.0%], respectively. This was significantly higher among the AFRS population compared to both the CRSwNP population (Δ34.2% [28.4%-39.6%], p < .0001) and the CRSsNP population (Δ44.9% [38.4%-50.6%], p < .0001). The proportion of patients who were either uninsured or covered by Medicaid among the AFRS, CRSwNP, and CRSsNP populations was 31.5% [25.4%-38.1%], 8.6% [0.7%-23.8%], and 5.0% [0.3%-14.8%], respectively. This was significantly higher among the AFRS group than the CRSwNP group (Δ22.9% [15.3%-31.1%], p < .0001) and the CRSsNP group (Δ26.5% [19.1%-33.4%], p < .0001). CONCLUSION This study confirms that AFRS patients are more likely to be Black and either uninsured or on subsidized insurance than their CRS counterparts.

Abstract
OBJECTIVE Make-at-home nasal irrigation solutions are often recommended for treating chronic rhinosinusitis. Many patients will store pre-made solution for convenient use. This study investigated the microbiological properties of differing recipes and storage temperatures. METHOD Three irrigation recipes (containing sodium chloride, sodium bicarbonate and sucrose) were stored at 5oC and 22oC. Further samples were inoculated with Staphylococcus aureus and Pseudomonas aeruginosa. Sampling and culturing were conducted at intervals from day 0-12 to examine for bacterial presence or persistence. RESULTS No significant bacterial growth was detected in any control solution stored at 5oC. Saline solutions remained relatively bacterial free, with poor survival of inoculated bacteria, which may be related to either lower pH or lower osmolality. Storing at room temperature increased the risk of contamination in control samples, particularly from pseudomonas. CONCLUSION If refrigerated, pre-made nasal irrigation solutions can be stored safely for up to 12 days without risking cross-contamination to irrigation equipment or patients.

Abstract
Introduction Although recent studies have shown that the human microbiome is involved in the pathogenesis of allergic diseases, the impact of microbiota on allergic rhinitis (AR) and non-allergic rhinitis (nAR) has not been elucidated. The aim of this study was to investigate the differences in the composition of the nasal flora in patients with AR and nAR and their role in the pathogenesis. Method From February to September 2022, 35 AR patients and 35 nAR patients admitted to Harbin Medical University's Second Affiliated Hospital, as well as 20 healthy subjects who underwent physical examination during the same period, were subjected to 16SrDNA and metagenomic sequencing of nasal flora. Results The microbiota composition of the three groups of study subjects differs significantly. The relative abundance of Vibrio vulnificus and Acinetobacter baumanni in the nasal cavity of AR patients was significantly higher when compared to nAR patients, while the relative abundance of Lactobacillus murinus, Lactobacillus iners, Proteobacteria, Pseudomonadales, and Escherichia coli was lower. In addition, Lactobacillus murinus and Lacttobacillus kunkeei were also negatively correlated with IgE, while Lacttobacillus kunkeei was positively correlated with age. The relative distribution of Faecalibacterium was higher in moderate than in severe AR patients. According to KEGG functional enrichment annotation, ICMT(protein-S-isoprenylcysteine O-methyltransferase,ICMT) is an AR microbiota-specific enzyme that plays a role, while glycan biosynthesis and metabolism are more active in AR microbiota. For AR, the model containing Parabacteroides goldstemii, Sutterella-SP-6FBBBBH3, Pseudoalteromonas luteoviolacea, Lachnospiraceae bacterium-615, and Bacteroides coprocola had the highest the area under the curve (AUC), which was 0.9733(95%CI:0.926-1.000) in the constructed random forest prediction model. The largest AUC for nAR is 0.984(95%CI:0.949-1.000) for the model containing Pseudomonas-SP-LTJR-52, Lachnospiraceae bacterium-615, Prevotella corporis, Anaerococcus vaginalis, and Roseburia inulinivorans. Conclusion In conclusion, patients with AR and nAR had significantly different microbiota profiles compared to healthy controls. The results suggest that the nasal microbiota may play a key role in the pathogenesis and symptoms of AR and nAR, providing us with new ideas for the treatment of AR and nAR.

Abstract
BACKGROUND Antibiotics are prescribed in >80% of outpatient acute rhinosinusitis (ARS) visits, despite the low incidence of bacterial infection. Previous studies have shown patient expectations are the most robust predictor of antibiotics prescription in ARS. However, patient perceptions are not well known or understood. OBJECTIVE To understand patient perceptions regarding what drives or deters them from wanting, seeking, and taking antibiotic treatment of ARS. DESIGN Iterative thematic analysis of semi-structured interviews. PARTICIPANTS Nineteen adults diagnosed with ARS within the prior 60 days at the Northwestern Medicine General Internal Medicine clinic in Chicago, IL. MAIN MEASURES Perceptions of patients with ARS. KEY RESULTS We interviewed 19 patients, identifying the following drivers of antibiotic use: (1) symptoms, especially discolored rhinorrhea, and seeking relief, (2) belief that antibiotics are a convenient and/or effective way to relieve/cure sinusitis, and (3) desire for tangible outcomes of a clinic visit. For deterrents, the following themes emerged: (1) concern about antibiotic resistance, (2) preference for other treatments or preference to avoid medications, and (3) desire to avoid a healthcare visit. Patients identified that a trustworthy physician's recommendation for antibiotics was a driver, and a recommendation against antibiotics was a deterrent to taking antibiotics; a delayed antibiotic prescription also served as a deterrent. Antibiotic side effects were viewed neutrally by most participants, though they were a deterrent to some. CONCLUSIONS Patients have misconceptions about the indications and effectiveness of antibiotics for ARS. Intimate knowledge of key antibiotic drivers and deterrents, from the perspective of patients with ARS, can be leveraged to engage and increase patients' knowledge, and set appropriate expectations for antibiotics for ARS.

Abstract
Chronic rhinosinusitis (CRS) is a common but burdensome ailment that is still poorly understood in terms of its pathogenesis. The existence of biofilms on the sinonasal mucosa of individuals with CRS has been proven by current biofilm identification methods. Current treatments for CRS generally include functional endoscopic sinus surgery, biofilm-removing strategies, and limited therapies that target quorum sensing (QS), patients with CRS are often resistant to antimicrobial therapy at degrees achievable by oral or intravenous administration, and even a subset of patients fail to react to either medical or surgical intervention. Multidrug-resistant Pseudomonas aeruginosa, Staphylococcus aureus, especially methicillin-resistant S. aureus, Streptococcus pneumoniae, and Haemophilus influenzae are the most commonly implicated bacteria in CRS patients, which may lead to the persistence and severity of CRS and antibiotic treatment failure via the formation of biofilms. Resistance to antibiotics is attributed to the 3-dimensional structure and QS of biofilms, and the latter describes the communication of bacteria within biofilms. A better understanding of biofilms in CRS and their contribution to the antibiotic resistance of CRS is critical for novel treatment strategies. This review mainly discusses the special structure of biofilms, QS, and their mechanisms of antibiotic resistance in order to investigate prospective anti-biofilm therapies, suggest future directions for study, and potentially refine the CRS prevention paradigm.

Abstract
PURPOSE To identify initial, preintervention magnetic resonance imaging (MRI) findings that are predictive of visual and mortality outcomes in acute invasive fungal rhinosinusitis (AIFRS). DESIGN Retrospective cohort study. PARTICIPANTS Patients with histopathologically or microbiologically confirmed AIFRS cared for at a single, tertiary academic institution between January 2000 and February 2020. METHODS A retrospective review of MRI scans and clinical records of patients with confirmed diagnosis of AIFRS was performed. For each radiologic characteristic, a modified Poisson regression with robust standard errors was used to estimate the risk ratio for blindness. A multivariate Cox proportional hazards model was used to study AIFRS-specific risk factors associated with mortality. MAIN OUTCOME MEASURE Identification of initial, preintervention MRI findings associated with visual and mortality outcomes. RESULTS The study comprised 78 patients (93 orbits, 63 with unilateral disease and 15 with bilateral disease) with AIFRS. The leading causes of immunosuppression were hematologic malignancy (38%) and diabetes mellitus (36%). Mucormycota constituted 56% of infections, and Ascomycota constituted 37%. The overall death rate resulting from infection was 38%. Risk factors for poor visual acuity outcomes on initial MRI included involvement of the orbital apex (relative risk [RR], 2.0; 95% confidence interval [CI], 1.1-3.8; P = 0.026) and cerebral arteries (RR, 1.8; 95% CI, 1.3-2.5; P < 0.001). Increased mortality was associated with involvement of the facial soft tissues (hazard ratio [HR], 4.9; 95% CI, 1.3-18.2; P = 0.017), nasolacrimal drainage apparatus (HR, 5.0; 95% CI, 1.5-16.1; P = 0.008), and intracranial space (HR, 3.5; 95% CI, 1.4-8.6; P = 0.006). Orbital soft tissue involvement was associated with decreased mortality (HR, 0.3; 95% CI, 0.1-0.6; P = 0.001). CONCLUSIONS Extrasinonasal involvement in AIFRS typically signals advanced infection with the facial soft tissues most commonly affected. The initial, preintervention MRI is prognostic for a poor visual acuity outcome when orbital apex or cerebral arterial involvement, or both, are present. Facial soft tissues, nasolacrimal drainage apparatus, intracranial involvement, or a combination thereof is associated with increased mortality risk, whereas orbital soft tissue involvement is correlated with a reduced risk of mortality.

Abstract
Chronic rhinosinusitis (CRS) is defined as an inflammatory disorder of the paranasal sinuses and of the nasal mucosa that lasts 12 weeks or longer. In CRS microbes contribute to the disease pathogenesis. Clinical microbiology is focused on finding single pathogens that causes the disease and the main goal is the use of antibiotics to kill bacteria. Efforts to achieve a better understanding of CRS include the study of the sinus microbiome, and to evaluate the ability of probiotics to augment homeostasis and modulate the immune response of the host mucosa. This review provides an update on the role of the microbiome in CRS. The study was conducted using two databases: PubMed and Science Direct. We searched for articles in English that matched the review topic. We first used the abstracts of articles to assess whether they met the inclusion criteria. We also reviewed the references of the selected articles and read those with titles that might be of interest. Several studies have shown that endogenous microbiome dysbiosis can impact mucosa health and disease severity. Some bacterial species presenting protective or pathogenic effect. Antimicrobial agents can create a similar disruption and impact the nasal microbiome balance. On the other hand, probiotics offers a promising avenue for developing systemic and topical therapies geared towards strategic manipulation of the biological host load, thereby augmenting immune homeostasis. A better comprehension of sinus-nasal microbiome in healthy and in CRS patients and the link with different CRS phenotype can help in developing new prognostics, diagnostics, and therapeutics strategies. Going forward, the use of probiotics can restore the native sinus ecology with significant therapeutic and preventive implications.

Abstract
Background Acute exacerbations (AE) in chronic rhinosinusitis (CRS) are a common and important clinical issue. However, relatively little is known regarding the underlying microbiology that drives exacerbations or how it relates to the microbiome of CRS. The purpose of this study is to examine the literature to characterize the microbiome associated with acute exacerbations in a chronic rhinosinusitis setting. Understanding this disease process may facilitate targeted antibiotic therapy, reduced antibiotic resistance, and offer more effective disease control and treatment efficacy. Objective To characterize the microbiome associated with acute exacerbations of chronic rhinosinusitis (AECRS). Methods We conducted a systematic review of the literature on Medline, Embase, and Web of Science databases from January 1990-June 2021 to identify studies related to AE in CRS. Exclusion criteria include non-English, non-human studies, and case reports. Studies without culture or PCR data were also excluded. Results Fourteen studies were identified which provided detailed data regarding sinus microbiome in AECRS patients. In these patients, a total of 1252 individual isolates were identified. While common acute pathogens were identified in high frequencies in the sinonasal cultures (Staphylococcus pneumonia, Haemophilus influenza), the predominant bacteria were Staphylococcus aureus (including methicillin-sensitive Staphylococcus aureus) and Pseudomonas aeruginosa. Patient characteristics that may represent higher risk phenotypes were not consistently collected in the studies. Discussion of antimicrobial sensitivities and/or resistance were included in 7/14 studies. Conclusions This systematic review identifies the predominant microbiology species that may contribute to AECRS. Further studies are needed to understand the pathogenic role of bacteria and viruses in AECRS and to identify associated comorbidities and patient phenotypes that may predispose to AE. The optimal treatment regimen for AECRS remains unclear.

Abstract
BACKGROUND Acute invasive fungal rhinosinusitis (AIFRS) is aggressive morbidity affecting immunocompromised patients. Coronavirus disease 2019 (COVID-19) may allow secondary fungal disease through a propensity to cause respiratory infection by affecting the immune system leading to dysregulation and reduced numbers of T lymphocytes, CD4+T, and CD8+T cells, altering the innate immunity. The aim of this study is to evaluate the incidence of acute invasive fungal rhinosinusitis (AIFRS) in COVID-19 patients. METHODOLOGY Data for acute invasive rhinosinusitis was obtained from the Otorhinolaryngology departments at our tertiary hospital at the period from January 2017 to December 2020. Then the risk factors of comorbid diseases and fungal types between post-COVID-19 and non-COVID-19 groups regarding the incidence of AIFRS are compared. RESULTS Consequently, the incidence of AIFRS showed a more significant difference (P < 0.05) in post-COVID-19 patients than in non-COVID-19 especially in immunocompromised patients, diabetic, renal, and liver dysfunction patients as well as patients with risk factors of AIFRS. The most common organisms affecting patients with AIFRS are Rhizopus oryzae, Aspergillus fumigatus, and Absidia mucor. CONCLUSIONS The incidence of AIFRS is markedly prominent in post-COVID-19 patients than in those of non-COVID-19, especially in immunocompromised, diabetic, renal, and liver dysfunction patients and patients with risk factors for rhinosinusitis.

<b>Background and Objective:</b> Detection of methicillin-resistant<i> S. aureus</i> have become a challenge in the presence of oxacillin-susceptible and <i>mecA</i>-positive <i>S. aureus </i>(OS-MRSA), concerning the misidentification events and therapeutic implications. This study aims to identify the OS-MRSA in clinical isolates of Post-viral acute rhinosinusitis, which, hopefully, can interfere with the therapeutic strategy. <b>Materials and Methods:</b> There were 60 patients diagnosed with Post-viral acute rhinosinusitis, recruited from an Ear, Nose and Throat (ENT) outpatient clinic. <i>Staphylococcus aureus</i> isolates were identified from the culture and were then tested for antibiotics susceptibility using a Kirby-Bauer disc diffusion test. The <i>mecA</i>, <i>mecC</i> and <i>blaZ</i> genes were determined using the Polymerase Chain Reaction (PCR) method. <b>Results:</b> <i>Staphylococcus aureus </i>was identified in 20 of the 60 samples from the patients (33.3%; 95% CI: 21.0-45.6). Of the 20 isolates, 19 isolates (95%) had a positive <i>mecA</i> gene, 19 (95%) had a positive <i>mecC</i> gene and 20 (100.0%) had a positive <i>blaZ </i>gene. The majority of the <i>mecA</i>-positive <i>S. aureus</i> showed an oxacillin-susceptible (85%) and 3 isolates (15.0%) were oxacillin-resistant toward the <i>S. aureus</i>. <b>Conclusion:</b> There was a high proportion of Oxacillin/cefoxitin-Susceptible <i>mecA</i>-positive <i>S. aureus</i> in the study population that indicate phenotypic susceptibility to antibiotics does not always indicate the absence of genes that carry resistant traits, thus allowing misidentification if the only phenotypic examination is carried out.

Abstract
AIMS 1: Describe the epidemiology and determine risk factors for COVID-19 associated mucormycosis. 2: Elaborate the clinical spectrum of Rhino-Orbital-Cerebral Mucormycosis (ROCM), pattern of neuroaxis involvement and it's radiological correlates. METHODS Observational study. Consecutive, confirmed cases of mucormycosis (N = 55) were included. A case of mucormycosis was defined as one who had clinical and radiological features consistent with mucormycosis along with demonstration of the fungus in tissue via KOH mount/culture/histopathological examination (HPE). Data pertaining to epidemiology, risk factors, clinico-radiological features were analysed using percentage of total cases. RESULTS Middle aged, diabetic males with recent COVID-19 infection were most affected. New onset upper jaw toothache was a striking observation in several cases. Among neurological manifestations headache, proptosis, vision loss, extraocular movement restriction; cavernous sinus, meningeal and parenchymal involvement were common. Stroke in ROCM followed a definitive pattern with watershed infarction. CONCLUSIONS New onset upper jaw toothache and loosening of teeth should prompt an immediate search for mucormycosis in backdrop of diabetic patients with recent COVID-19 disease, aiding earlier diagnosis and treatment initiation. Neuroaxis involvement was characterized by a multitude of features pertaining to involvement of optic nerve, extraocular muscles, meninges, brain parenchyma and internal carotid artery.

Abstract
Chronic rhinosinusitis (CRS) affects nearly all individuals with cystic fibrosis (CF) and is thought to serve as a reservoir for microbiota that subsequently colonize the lung. To better understand the microbial ecology of CRS, we generated a 16S rRNA gene sequencing profile of sinus mucus from CF-CRS patients. We show that CF-CRS sinuses harbor bacterial diversity not entirely captured by clinical culture. Culture data consistently identified the dominant organism in most patients, though lower abundance bacteria were not always identified. We also demonstrate that bacterial communities dominated by Staphylococcus spp. were significantly more diverse compared to those dominated by Pseudomonas spp. Diversity was not significantly associated with clinical factors or patient age, however, younger subjects yielded a much wider range of bacterial diversity. These data mirror bacterial community dynamics in the lung and provide additional insight into the role of sinus microbiota in chronic airway disease progression.

Abstract
The pathogenesis of nasal inflammatory diseases is related to various factors such as anatomical structure, heredity, and environment. The nasal microbiota play a key role in coordinating immune system functions. Dysfunction of the microbiota has a significant impact on the occurrence and development of nasal inflammation. This review will introduce the positive and negative roles of microbiota involved in immunity surrounding nasal mucosal diseases such as chronic sinusitis and allergic rhinitis. In addition, we will also introduce recent developments in DNA sequencing, metabolomics, and proteomics combined with computation-based bioinformatics.

Abstract
This proof-of-concept study demonstrates that sinonasal microbiome sequencing with suctioned nasal secretions in children is technically feasible. Eighteen children were enrolled: 11 with symptoms of rhinosinusitis and 7 controls. Samples were collected via a sterile flexible respiratory suction catheter into a suction trap. Samples were analyzed with 16S ribosomal RNA sequencing and subsequent phylogenic mapping. The log2-fold differential abundance in class demonstrated significantly higher quantities of bacteria from the classes Negativicutes, Bacilli, Mollicutes, and Alphaproteobacteria as compared with controls, with a false discovery rate-corrected P value <.01 for all 4. The experimental group showed a higher range of alpha diversity than the control group, although none of the measures of alpha diversity showed a statistically significant difference. Overall our study demonstrates that sinonasal microbiome sequencing with suctioned nasal secretions is a readily available and technically feasible alternative for study of the pediatric sinonasal microbiome.

Abstract
Chronic rhinosinusitis (CRS) is a chronic disease that involves long-term inflammation of the nasal cavity and paranasal sinuses. Bacterial biofilms present on the sinus mucosa of certain patients reportedly exhibit resistance against traditional antibiotics, as evidenced by relapse, resulting in severe disease. The aim of this study was to determine the killing activity of human cathelicidin antimicrobial peptides (LL-37, LL-31) and their D-enantiomers (D-LL-37, D-LL-31), alone and in combination with conventional antibiotics (amoxicillin; AMX and tobramycin; TOB), against bacteria grown as biofilm, and to investigate the biological activities of the peptides on human lung epithelial cells. D-LL-31 was the most effective peptide against bacteria under biofilm-stimulating conditions based on IC50 values. The synergistic effect of D-LL-31 with AMX and TOB decreased the IC50 values of antibiotics by 16-fold and could eliminate the biofilm matrix in all tested bacterial strains. D-LL-31 did not cause cytotoxic effects in A549 cells at 25 μM after 24 h of incubation. Moreover, a cytokine array indicated that there was no significant induction of the cytokines involving in immunopathogenesis of CRS in the presence of D-LL-31. However, a tissue-remodeling-associated protein was observed that may prevent the progression of nasal polyposis in CRS patients. Therefore, a combination of D-LL-31 with AMX or TOB may improve the efficacy of currently used antibiotics to kill biofilm-embedded bacteria and eliminate the biofilm matrix. This combination might be clinically applicable for treatment of patients with biofilm-associated CRS.

Abstract
We hypothesized that differences in the microbiome could be a cause of the substantial differences in the symptoms of and treatment options for adult and pediatric patients with chronic rhinosinusitis (CRS). First, we characterized the differences in the nasal microbiomes of pediatric and adult CRS patients. Swabs were obtained from 19 patients with chronic rhinosinusitis (9 children and 10 adults). The bacterial 16S rRNA gene was pyrosequenced to compare the microbiota of the middle meatus. No significant differences were found in species richness and alpha-diversity indices between the two groups. However, in the comparison of diversity between groups using the unweighted pair group method with arithmetic mean (UPGMA) clustering of microbiome taxonomic profiles, we observed a relatively clear separation between the adult and pediatric groups. Actinobacteria had a significantly higher relative abundance in the adult group than in the pediatric group at the phylum level. At the genus level, Corynebacterium showed significantly higher relative abundance in the adult group than in the pediatric group. This is a comparative study between the microbiomes of adult and pediatric CRS patients. We expect this study to be the first step in understanding the pathogenesis of CRS in adults and children using microbiome analysis.

Abstract
Fungal rhinosinusitis (FRS) is inflammation of the paranasal sinus mucosa due to fungal infections, which can be invasive or non-invasive. The occurrence of a sphenoid mucocele with a fungal ball is rare. We report a case of sphenoid sinus mucocele with a fungal ball caused by Scedosporium apiopermum in a 32-year-old female who presented to the Emergency Department with persistent headache not relieved on medications. The radiological images showed a mucocele with clival osteomyelitis. Urgent endoscopic examination and debridement was undertaken which demonstrated a mucocele with fungal ball. Microbiological examination confirmed it to be Scedosporium apiopermum.

Abstract
Acute otitis media, acute bacterial rhinosinusitis, and community-acquired pneumonia are major drivers of pediatric antibiotic consumption. With many available options and the added challenges of navigating antibiotic allergies and de-escalating from intravenous treatment for children requiring hospitalization, prescribing for these relatively simple infections can be a source of confusion and error. The purpose of this article is to evaluate the pharmacokinetic and pharmacodynamic properties of antibiotics commonly prescribed for these disease states, and to specifically compare antipneumococcal activity between oral beta-lactams.

Abstract
PURPOSE Chronic rhinosinusitis (CRS) is one of the most common chronic diseases in the geriatric population. However, CRS inflammatory mechanisms in older people have not been thoroughly investigated. Our work aimed to analyze the bacterial flora of the nose and paranasal sinuses in patients with CRS over 65 years of age, including comorbidities, previously performed endoscopic sinus surgery (ESS), presence or absence of polyps and the extent of the inflammatory process. PATIENTS AND METHODS The study involved 529 patients between 18 and 84 years of age with chronic rhinosinusitis who underwent endoscopic sinus surgery. There were 101 patients separated over 65 years of age (M = 52, K = 49, mean age 69 ± 0.7 years). The control group consisted of 168 patients aged 18-40 years with CRS. The bacterial culture of material collected from the patients during ESS was analyzed. RESULTS In the group of patients over 65 years of age, more frequent occurrence of Proteus spp. and Pseudomonas aeruginosa was found in comparison to younger patients. In older patients with bronchial asthma, the occurrence of S. aureus, Escherichia coli, and Citrobacter spp. was more frequent than in control group. Multiple sinus surgical procedures in older patients were associated with the dominance of Staphylococcus aureus and Escherichia coli, which was not demonstrated in the control group. There were no statistically significant differences between the occurrence of bacterial strain and the presence of polyps, both in the group of patients over 65 years of age as well as in the control group. CONCLUSION The bacterial flora of patients with CRS is different in older and younger patients. A different therapeutic approach should be considered in older patients with CRS, but this problem requires further studies.

Abstract
OBJECTIVES The aim of this study was to analyze the rate of admissions, the rate of serious complications (postseptal orbital complications and surgery) and the bacterial etiology of acute rhinosinusitis in hospitalized children under five years old in Stockholm County, eight years after the introduction of the pneumococcal conjugate vaccine (PCV). The secondary aim was to compare this period with the period four years prior to the vaccine's introduction. METHODS This was a population-based, descriptive observational study with retrospectively collected data from 1 July 2008 to 30 June 2016 in Stockholm County. Hospital admissions of children with a discharge diagnosis of rhinosinusitis and related complications were reviewed and compared to the pre-PCV period of 2003-2007. RESULTS A total of 215 children were admitted, for a yearly incidence of 18.8 per 100 000 children (22.8 for boys, 14.6 for girls). Computer tomography-verified postseptal orbital complications occurred in 29 cases (13.5%) and surgery was necessary in nine (4.2%). Pathogens other than Streptococcus pneumoniae were found in the cases with postseptal complication or surgery (Streptococcus pyogenes in four, Haemophilus influenzae in three and Staphylococcus aureus in one case). In comparison to the four years pre-PCV, the incidence of admission decreased from 43.81 to 20.31 and 17.45 per 100 000/year for the two four-year periods after vaccine introduction. The incidence of CT-verified postseptal complication increased slightly from 1.51 to 2.34 and 2.74 per 100 000/year. The incidence of surgeries increased marginally but continued to be very low, from 0.22 to 0.54 and 1.03 per 100 000/year. CONCLUSIONS Complications due to acute rhinosinusitis in children living in Stockholm County continues to be very rare after the introduction of pneumococcal vaccine. Hospitalization has decreased for children under five years old after PCV introduction, but the incidence or postseptal complications and surgery in the same population increased slightly. Predominantly bacteria other than Streptococcus pneumoniae was found. There is a need of larger studies to determine trends, and a need of prospective studies to elucidate the bacterial etiology, of serious complications due to acute rhinosinusitis in children.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by TH2-skewed inflammation and increased colonization by Staphylococcus aureus. IFN-λ1 is known for its antiviral activity, but there is little information on its antibacterial role. OBJECTIVE We sought to determine the expression and release of IFN-λ1 from nasal mucosal tissue of healthy subjects and patients with CRSwNP on exposure to S aureus and assess its potential role in antibacterial defense mechanisms. METHODS Nasal tissue from healthy subjects and patients with CRSwNP was exposed to S aureus, and we assessed expression of IFN-λ1, MUC5AC, and MUC5B. THP1-derived macrophages incubated with or without IFN-λ1 were assessed for uptake and killing of S aureus and expression of lysosomal-associated membrane protein 1 and intracellular reactive oxidase substrate (ROS), the IFN-λ1 receptor IL-28 receptor (IL-28R), and the Janus kinase/signal transducer and activator of transcription (STAT) 1 pathway by means of immunofluorescence staining. RESULTS S aureus infection increased IFN-λ1 expression in tissue from patients with CRSwNP. IFN-λ1 (10 ng/mL) significantly decreased the number of S aureus colony-forming units in healthy control tissue but not in tissue from patients with CRSwNP and upregulated MUC5AC and MUC5B expression in control tissue on S aureus infection. IFN-λ1 stimulation increased intracellular killing of S aureus in THP1-derived macrophages and substantially increased lysosomal-associated membrane protein 1, IL-28R, ROS, and STAT signaling in macrophages incubated with S aureus. All of these effects were attenuated by blocking IL-28R and ROS activities. CONCLUSIONS IFN-λ1 favors clearance of S aureus in healthy nasal mucosa and enhances antibacterial function of macrophages through IFN-λ1-IL-28R-ROS-Janus kinase-STAT signaling pathways.

Abstract
BACKGROUND Potential effects of aging on chronic rhinosinusitis (CRS) pathophysiology have not been well defined but might have important ramifications given a rapidly aging US and world population. OBJECTIVE The goal of the current study was to determine whether advanced age is associated with specific inflammatory CRS endotypes or immune signatures. METHODS Levels of 17 mucus cytokines and inflammatory mediators were measured in 147 patients with CRS. Hierarchical cluster analysis was used to identify and characterize inflammatory CRS endotypes, as well as to determine whether age was associated with specific immune signatures. RESULTS A CRS endotype with a proinflammatory neutrophilic immune signature was enriched in older patients. In the overall cohort patients 60 years and older had increased mucus levels of IL-1β, IL-6, IL-8, and TNF-α when compared with their younger counterparts. Increases in levels of proinflammatory cytokines were associated with both tissue neutrophilia and symptomatic bacterial infection/colonization in aged patients. CONCLUSIONS Aged patients with CRS have a unique inflammatory signature that corresponds to a neutrophilic proinflammatory response. Neutrophil-driven inflammation in aged patients with CRS might be less likely to respond to corticosteroids and might be closely linked to chronic microbial infection or colonization.

Abstract
We studied dampness and mold in China in relation to rhinitis, ocular, throat and dermal symptoms, headache and fatigue. A questionnaire study was performed in six cities including 36 541 randomized parents of young children. Seven self-reported signs of dampness were evaluated. Multilevel logistic regression models were used to calculate odds ratios (ORs). Totally, 3.1% had weekly rhinitis, 2.8% eye, 4.1% throat and 4.8% skin symptoms, 3.0% headache and 13.9% fatigue. Overall, 6.3% of the homes had mold, 11.1% damp stains, 35.3% damp bed clothing, 12.8% water damage, 45.4% window pane condensation, 11.1% mold odor, and 37.5% humid air. All dampness signs were associated with symptoms (ORs from 1.2 to 4.6; P < 0.001), including rhinitis (ORs from 1.4 to 3.2; P < 0.001), and ORs increased by number of dampness signs. The strongest associations were for mold odor (ORs from 2.3 to 4.6) and humid air (ORs from 2.8 to 4.8). Associations were stronger among men and stronger in Beijing as compared to south China. In conclusion, dampness and mold are common in Chinese homes and associated with rhinitis and ocular, throat and dermal symptoms, headache and fatigue. Men can be more sensitive to dampness and health effects of dampness can be stronger in northern China.

Abstract
Objective To analyze the risk factors of multidrug-resistant bacterial infections in patients with chronic rhinosinusitis.Methods The clinical data of 221 patients with chronic rhinosinusitis who were treated in our center from January 2010 to January 2017 were collected retrospectively. Specimens were collected for bacterial culture and antibiotic susceptibility testing. The risk factors for multidrug-resistant bacterial infections were analyzed.Results Univariate analysis showed that combined use of 3 or more antibiotics,high visual analogue scale score,high Lund-Kennedy score,long disease course(>5 years),high frequency of acute infections(more than 3 times a year),long duration of acute infection(>7 days),recurrent upper respiratory tract infections(>3 times per year),chronic otitis media,smoking history,allergic rhinitis,poor drainage,high frequency of antimicrobial use(≥3 times/year),use of multiple antibiotics(more than 3 types),aged over 60 years,and use of antibacterial drugs for over 7 days were the risk factors for production of multi-drug-resistant organism(MDRO) in patients with chronic sinusitis(all P<0.05). After adjusting for other factors,combined use of 3 or more antibiotics,high frequency of acute infections(more than 3 times a year),recurrent upper respiratory tract infections(>3 times per year),smoking history,allergic rhinitis,poor drainage,and high frequency of antimicrobial use(≥3 times/year) remained the risk factors for MDRO in patients with chronic sinusitis(all P<0.05).Conclusions Multidrug-resistant bacterial infections in patients with chronic sinusitis can be caused by a variety of factors. In the clinical practice,by focusing on the major risk factors,a comprehensive management strategy should be adopted to reduce the production of MDRO and improve the therapeutic outcomes.

Abstract
Aim - Improvement of polypous rhinosinusitis anti-relapse treatment efficacy by distinguishing of the core meaningful factors of the disease's development. The study included 300 patients with polypous rhinosinusitis aged 18-77 years. Comprehensive evaluation of the data is done by means of factor analysis by the method of the main components with subsequent varimax-rotation of the factor axes. The critical value of p-level was 0.05. As a result of the factorial analysis, 6 main factors were identified, the joint action of which explains 53.72% of the variability of indicators for the polypous rhinosinusitis. The factor analysis allowed to distinguish the groups of indicators and estimate the specific weight of individual pathogenetic factors in the development of polypous rhinosinusitis, which might be conditionally combined under the general names of «clinic-immune», «clinic-pathomorphological», «immunoregulatory», «clinical-microbiological», «violation local protection»,»epidemiological and demographic «factors. The effect of two of the most powerful factors («clinical-immune» and «clinic-pathomorphological factor») is explained by 46.47% of the variability of indicators. Factor estimates for the most potent «clinically-immune-causative factor» with a high degree of reliability distinguished groups of patients with the first identified polypous rhinosinusitis and its relapse. Perspectives of further investigations are related to mathematical modeling of the pathological process using artificial neural networks.

Abstract
RATIONALE Surgical intervention may be not a contraindication for acute invasive fungal rhinosinusitis (AIFR) during the pre-engraftment period of allogeneic hematopoietic stem cell transplantation (allo-HSCT). PATIENT CONCERNS We present 2 cases involving patients with AIFR in the pre-engraftment phase of allo-HSCT. DIAGNOSES Both patients received surgical debridement combined with systemic antifungal treatment. The biopsies identified the diagnosis of AIFR in these 2 cases. OUTCOMES The 2 patients obtained normal hematopoiesis without recurrence of AIFR. LESSON Our experience with these 2 cases suggests that prompt endoscopic surgical debridement is not an absolute contraindication for allo-HSCT recipients with AIFR during the pre-engraftment period. If permitted, urgent, radical, and aggressive but careful endoscopic debridement should be performed together with systemic antifungal treatment once AIFR has been diagnosed or suspected.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is an inflammatory disorder of the nose and sinuses. Since fungi were postulated as a potential cause of CRS in the late 1990s, there has been increasing controversy about the use of both topical and systemic antifungal agents in its management. Although interaction between the immune system and fungus has been demonstrated in CRS, this does not necessarily imply that fungi are the cause of CRS or that antifungals will be effective its management. OBJECTIVES To assess the effectiveness of topical or systemic antifungal therapy in the treatment of CRS. SEARCH METHODS We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 8 March 2011. SELECTION CRITERIA All randomised, placebo-controlled trials considering the use of topical or systemic antifungal therapy in the treatment of CRS and allergic fungal sinusitis (AFS). CRS was defined using either the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) or American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) criteria. DATA COLLECTION AND ANALYSIS We reviewed the titles and abstracts of all studies obtained from the searches and selected trials that met the eligibility criteria. We extracted data using a pre-determined data extraction form. There was significant heterogeneity of outcome data reporting with reports containing both parametric and non-parametric representations of data for the same outcomes. Means and standard deviations for change data were unavailable for a number of trials. Due to the limited reported data, we contacted authors and used original data for data analysis. MAIN RESULTS Six studies were included (380 participants). Five studies investigated topical antifungals and one study investigated systemic antifungals. The risk of bias in all included studies was low, with all trials being double-blinded and randomised. Pooled meta-analysis showed no statistically significant benefit of topical or systemic antifungals over placebo for any outcome. Symptom scores in fact statistically favoured the placebo group. Adverse event reporting was statistically significantly higher in the antifungal group. AUTHORS' CONCLUSIONS On the basis of this meta-analysis, there is no evidence to support the use of either topical or systemic antifungal treatment in the management of CRS.

Abstract
This study aimed to evaluate the antimicrobial effects of the medicinal plant Ecballium elaterium, which is topically applied as a traditional medicine for the treatment of rhinosinusitis. Pure and extract forms of E elaterium were applied to the nasal cavity of rats for the treatment of Streptococcus-pneumoniae -induced rhinosinusitis. The nasal mucosa, soft palate, and trachea of the rats were harvested in the first hour, third day, and third week for histopathologic evaluation. This experiment revealed the anti-inflammatory effects of E elaterium and showed that it reduced fibrosis. The anti-inflammatory effect of all forms of E elaterium was found to reach its maximum level on the third day, decreasing by the third week. We also observed that the pure form of E elaterium caused severe epithelium loss in the first hour after application. The mechanism of the anti-inflammatory effect of different levels of extract forms needs to be further analyzed with different doses and duration of treatment.

Abstract
Background The aim of this study was to review the presentation and management of children admitted for intracranial complications arising from frontal rhinosinusitis. We performed a retrospective case series review at two academic tertiary care children's hospitals. Methods This study consisted of children <18 years old who presented with intracranial complications from frontal rhinosinusitis between January 1, 1990 and December 31, 2002. Relevant literature was reviewed with the assistance of Medline. Presentation, type of intracranial complication, radiographic evaluations, response to treatment, and prognosis were evaluated. Results Sixteen patients were identified with intracranial complications due to frontal rhinosinusitis. Patients were usually older (mean age, 14 years and 3 months), of male gender (M/F, 4.3:1.0), and African American (AA/W, 3.0:1.0). Headache, nasal congestion, and visual changes were the most common early symptoms and neurological findings indicated advanced disease. Subdural (56%), epidural (44%), and cerebral abscesses (19%) were the most common complications. Meningitis alone was identified in 13% and was associated with another intracranial complication in 6%. Multiple intracranial complications were noted in 31%. Polymicrobial cultures were obtained in 50% of patients. Although CT was excellent in identifying orbital pathology, MRI was superior for characterization of intracranial disease. Conclusion Intracranial complications of frontal rhinosinusitis are rare in children. Early symptoms often are nonspecific, with neurological findings more commonly seen in advanced disease. Adolescent African American male patients were found to be at highest risk for intracranial complications from frontal rhinosinusitis. Headache and orbital complaints associated with rhinosinusitis in older children failing to respond to initial therapy should prompt an aggressive evaluation including MRI.

Abstract
Background Patients who undergo radiotherapy for nasopharyngeal carcinoma (NPC) tend to suffer from rhinosinusitis because irradiation causes damage to sinonasal tissue; however, their bacteriology is lacking in the literature. The aim of this study was to determine the bacteriology and antibiotic resistance in acute rhinosinusitis (ARS) of these patients. Methods We collected nasal purulent discharge for bacteriology and antibiotic susceptibility tests in irradiated NPC patients with ARS. Middle meatus discharge was aspirated for culture with endoscopic assistance. Results A total of 33 episodes of ARS were documented in 25 patients. Staphylococcus aureus comprised 42% of all aerobes. Thirty-six percents of aerobic isolates were Gram-negative bacilli. Peptostreptococcus micros and Veillonella spp were the most frequently isolated anaerobes. Conclusion The bacteriology in irradiated NPC patients with ARS was distinctive in the following: first, the most common pathogen was S. aureus; second, frequently isolated Gram-negative bacilli and anaerobes; and third, polymicrobial infections. The β-lactamase–producing pathogens were highly prevalent.

Abstract
Background Bacterial biofilms may be involved in refractory chronic rhinosinusitis (CRS). In vitro, we studied methods for removing biofilms formed by Staphylococcus aureus and Pseudomonas aeruginosa. Methods Bacterial isolates were obtained from patients with refractory CRS and were plated and treated with either static administration of citric acid/zwitterionic surfactant (CAZS), saline delivered with hydrodynamic force, or CAZS delivered hydrodynamically. Results were assessed by counting colony-forming units (CFUs) and by confocal scanning laser microscopy (CSLM). Results All treatments produced significant reductions in CFU counts (p ≥ 0.002). Hydrodynamic CAZS provided the greatest reduction, decreasing CFU counts from control values by 3.9 ± 0.3 logs and 5.2 ± 0.5 logs for S. aureus and P. aeruginosa, respectively (99.9% reduction; p = 0.001). CSLM showed decreases in biofilm coverage. Conclusion Hydrodynamic delivery of a soap-like surfactant and a calcium-ion sequestering agent may disrupt biofilms associated with CRS. Our results may be relevant to a new approach to refractory CRS.

Abstract
Background In vitro biofilm-producing capacity in isolates of Staphylococcus aureus and Pseudomonas aeruginosa collected from the sinus cavities after endoscopic sinus surgery (ESS) are associated with a poor outcome in patients with chronic rhinosinusitis (CRS). However, conventional oral antibiotic therapy is frequently ineffective in eradicating bacteria in the biofilm form. Increasing the concentration of antibiotics may offer a means of countering this resistance. The aim of this study was to determine the in vitro activity of moxifloxacin (MOXI) against S. aureus in biofilm form (recovered from patients with CRS at least 1 year post-ESS). Method This study was performed in a research microbiology laboratory, where five isolates of S. aureus with known biofilm-forming capacity were cultured in Tryptic Soy Broth 0.5% glucose in 96-well plates at 37°C for 24 hours. After visual confirmation of biofilm formation, plates were incubated in phosphate-buffered saline (PBS) or with MOXI at concentrations of 0.1×, 1×, 100×, and 1000× minimal inhibitory concentration (MIC) for an additional 24 hours. Biofilm from 3 wells of each concentration were collected and sonicated and the number of viable bacteria was determined by serial dilution and plating. Results After incubation, the number of viable bacteria was similar for nontreated and MOXI-treated biofilms at MIC and sub-MIC levels. However, MOXI at 1000X (0.1–0.2 mg/mL) gave a 2 to 2.5 log reduction in number of viable bacteria. Conclusion In vitro results show that increased concentrations of antibiotics, easily attainable in topical solutions, are effective in killing bacteria in bacterial biofilms. This suggests a role for topical antibiotic therapies in the treatment of biofilm infections.

Abstract
Objective:To investigate the bacteriologic characteristics of recurrent acute rhinosinusitis(RAR).Method:Twenty-nine patients (29 with RAR) from outpatient clinic in our hospital between June 2010 and May 2016 were enrolled in the study. Specimens of the middle meatus or olfactory cleft area using the sinus endoscopy through were transported to the laboratory for bacterial culture.Result:Twenty-five specimens out of 29 were bacterial culture positive (culture positive rate was 86.2%).A total of 32 isolates (25 aerobic or facultative and 7 anaerobic) were recovered from the 29 cases of RAR. The predominant aerobic or facultative bacteria were Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Staphylococcus aureus. The predominant anaerobic bacteria were Bacteroides fragilis and Propionibacterium. Antibiotic susceptibility tests showed that the resistance rate of these aerobic or facultative bacteria to Macrolides (Erythromycin and Azithromycin) and quinolones (Levofloxacin) was 88% and 92%, respectively. Similarly, the resistance rate of bacteria to β-lactamase antibiotics (penicillin, ampicillin, and cefazolin) was also greater than 90% (100%, 92%, and 92%, respectively). But the drug resistance of these bacteria to the thirdgeneration cephalosporin combined with beta lactamase inhibitors (Cefoperazone/sulbactam) was 20%. Among the 7 strains of anaerobic bacteria, 6 strains were sensitive to ornidazole.Conclusion:The major pathogens of RAR are the aerobic and facultative bacteria Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Staphylococcus aureus, most of which are resistant to commonly used antibiotics.

Abstract
Invasive fusariosis has a high mortality and is predominantly observed in patients with leukemia. We report the first case of a novel species of Fusarium, Fusarium riograndense sp. nov, isolated from a lesion in the nasal cavity lesion of a patient with acute lymphoblastic leukemia. The etiological agent was identified by Multilocus Sequencing Typing (MLST), including RPB2, TEF-1α, and ITS-LSU sequences, the gold standard technique to identify new species of Fusarium. MLST and phenotypic data strongly supported its inclusion in the F. solani species complex (FSSC). The new species produced a red pigment in the Sabouraud Dextrose Agar similar to other members of the complex. The macroconiodia developed from phialides on multibranched conidiophores which merge to form effuse sporodochia with a basal foot-cell instead of papilla in basal cell shape. The microconidia were ellipsoidal, 0-1-septated, produced from long monophialides. Chlamydospores were produced singly or in pairs. Amphotericin B (MIC 1μg/mL) was the most active drug, followed by voriconazole (MIC 8μg/mL). The patient was successfully treated with voriconazole. Our findings indicate another lineage within FSSC capable causing of invasive human infection.

Abstract
OBJECTIVE The incidence of refractory chronic rhinosinusitis (CRS) associated with methicillin-resistant Staphylococcus aureus (MRSA) is rising and remains a therapeutic challenge. The goal of this study is to demonstrate the efficacy of a non-invasive topical therapy against MRSA in these patients. METHODS Seventeen patients with refractory CRS caused by MRSA were treated with a topical therapy protocol. Treatment consisted of weekly endoscopic sinus debridement followed by intra-sinus installation of a hydroxyl-ethylcellulose gel that releases mometasone and a culture-directed antibiotic for a period of 6 weeks, along with daily nasal nebulization of mometasone with the same antibiotic and saline rinses. Clinical outcome was assessed using the Lund-Kennedy (LK) symptom and endoscopic appearance scores. Sinus mucosal tissue was homogenized and cultured, and microbial biofilm burden was assessed based on colony forming units (CFUs) counts. RESULTS Rhinotopic therapy resulted in clearance of MRSA in 13 of 16 patients (81.2%). Treated patients also demonstrated significant improvement clinically as measured by the LK scores. In addition, a significant decrease in mucosal CFUs was observed post-therapy. CONCLUSION Our findings demonstrate that topical therapy is an effective method for treating MRSA-associated refractory CRS.

Abstract
INTRODUCTION Published studies have reported a rise in MRSA isolates in head and neck infections, but the microbiology of complicated pediatric rhinosinusitis is unclear. One study of such patients showed that MRSA isolates were seen only in the last three years of data collection, suggesting a possible recent increased prevalence. Given the public health concerns of increasing rates of antimicrobial resistance, the goal of this study was to investigate the microbiologic patterns and outcomes of complicated pediatric rhinosinusitis. METHODS Retrospective cohort of pediatric patients admitted to our children's hospital with complicated acute rhinosinusitis from 2004 to 2014. RESULTS The mean age of 250 hospitalized children with complicated rhinosinusitis was 7.6 ± 4.9 years; 109 of these (43%) underwent surgical procedures. Although MRSA prevalence was highest in 2014, no significant trend in overall MRSA prevalence occurred when considering the entire study period. No significant relationship was identified between MRSA and intra-orbital versus intra-cranial complications. Interestingly, 22.7% of patients with anaerobes detected by culture had persistent abnormal physical examination (PE) findings versus 6.1% of patients without anaerobes (p = 0.025). Furthermore, multivariate analysis also revealed that detection of anaerobes or MRSA was associated with persistent PE findings being 21.8 and 14.8 times more likely, respectively, when compared to other detected pathogens. DISCUSSION Our data indicate modest variability in the annual rates of MRSA associated pediatric rhinosinusitis, however there was no statistically significant pattern of change in MRSA prevalence during 2004-2014. Although detection of MRSA was not significantly associated with either intraorbital or intracranial complications of sinusitis, a significant association with a poorer outcome was observed by multivariate analysis for patients from whom MRSA or anaerobes were detected. These data raise the question as to whether clindamycin is adequate for MRSA and anaerobic coverage.

Abstract
OBJECTIVE The aim of this study was to evaluate the reparative role of hyaluronic acid in acute rhinosinusitis (ARS). PATIENTS AND METHODS 48 patients affected by ARS were submitted to nasal endoscopy, nasal cytology, mucociliary transport evaluation (MCTt) and visual analogue scale questionnaire (VAS) at T0, after 14-18 days (T1) and after 30-35 days (T2). The patients were randomized into two groups, A and B, and received Levofloxacin and Prednisone. Moreover, using a nebulizer ampoule for nasal douche, Group A received high molecular weight Sodium Hyaluronate (3%) plus saline solution (NaCl 0.9%) twice a day for 30 days; Group B received saline solution twice a day for 30 days. RESULTS At T0 only the VAS score showed differences regarding nasal discharge and post-nasal drip. At T1, in Group A MCTt and the number of bacteria were significantly lower than in Group B. The VAS score showed improvement in Group A. At T2 in Group A, MCTt and number of neutrophils were significantly lower than in Group B. The VAS score showed statistically significant differences between the two groups regarding nasal discharge. CONCLUSIONS In ARS patients sodium hyaluronate plus saline solution significantly improved symptoms, MCT time and reduced neutrophil count on nasal cytology.

Abstract
PURPOSE To investigate outcomes of pediatric patients at a single institution with invasive fungal rhinosinusitis (IFRS) and to determine variables that impact overall survival. METHODS All pediatric patients at a large tertiary children's hospital diagnosed with IFRS confirmed by surgical pathology from 2009 to 2015 were retrospectively reviewed. Demographics, underlying diseases, symptoms, antifungal therapy, absolute neutrophil count (ANC), surgical management,and outcomes were analyzed. RESULTS Seventeen patients were identified with IFRS with an average age of 8.7 years and 53% male. Hematologic malignancy was the most common (n = 13) underlying disease. The most common presenting symptoms were fever (82%) and congestion (41%). 15 patients had severe neutropenia (Absolute Neutrophil Count (ANC) < 500) within 2 weeks prior to diagnosis. The average ANC at time of diagnosis was 1420 cells/uL. 16 patients were treated with serial nasal endoscopy and debridement, while 1 patient was treated with an open approach. 16 received combination antifungals while 1 was treated with amphotericin monotherapy. The most common genus cultured was Fusarium (n = 6). The average number of surgical interventions was 3.4, with the average interval between interventions 6.2 days. 13 of 17 (76%) were cleared of IFRS. Overall survival at 6 months was 41%. CONCLUSION Pediatric IFRS is a life-threatening disease that requires a coordinated surgical and medical approach. Despite a relatively high local control rate, overall mortality remains disappointingly high, reflecting the disease's underlying pathogenesis - lack of host defense and risk of disseminated fungal infection. Further investigation is necessary to reveal optimal management with regards to antifungal therapy, surgery, and utility of labs.
