Abstract
OBJECTIVE/HYPOTHESIS To compare pre-and post-operative pulmonary function relative to disease severity in cystic fibrosis (CF) patients following endoscopic sinus surgery (ESS). STUDY DESIGN Retrospective chart review. METHODS Patients with CF who underwent ESS between January 1996 and July 2018 were identified, with subsequent study exclusions based upon surgical indications or incomplete records. CF disease severity was based upon percentage predicted of forced expiratory volume in 1 second (%FEV1) with <40% considered severe disease, 40% to 70% as moderate disease, and >70% as mild disease. The changes in %FEV1 before and after ESS were examined using multivariable mixed-effects models controlling for age, gender, genotype, medications, nutritional status, diabetes status, microbiology results, extent of surgery, and number of surgeries. RESULTS A total of 427 surgeries were performed in 188 patients during the study period. Mean age at first ESS was 12.7 years (SD 6.0 years, range 4-38) and 54.8% were females. The effect of ESS varied by severity of lung disease. After surgery, %FEV1 increased by 8.1% (95% CI: 2.3, 13.9%) among patients with severe lung disease and by 3.0% (95% CI: 0.7, 5.2%) among patients with moderate disease. %FEV1 also increased by 7.3% (95% CI: 4.2, 10.5%) among patients with mild disease whose %FEV1 value was 70% to 80% at baseline. No improvement was observed in patients with a baseline %FEV1 >80%. CONCLUSIONS When controlling for important confounding factors, lung function improved following ESS among CF patients with severe and moderate disease and in select patients with mild disease. This improvement was sustained at 12 months following surgery. LEVEL OF EVIDENCE 4 Laryngoscope, 131:1930-1938, 2021.

Abstract
Asthma has been implicated as a driving force in lower airway remodeling; however, its effect on upper airway development has not been studied. Clinical disease, particularly cystic fibrosis (CF), has been associated with anatomical paranasal sinus variation, although the mechanism for these variations remains unclear. The purpose of this study was to determine whether asthma is associated with altered sinus pneumatization. Five hundred ninety-one computed tomography scans, including 303 adolescents (age 13-18) and 288 adults (age > 18), were evaluated using the Assessment of Pneumatization of the Paranasal Sinuses (APPS) instrument. The APPS score is validated for assessing anatomical variation and total sinus volume. A diagnosis of asthma was ascertained from the medical record, and patients with CF were included as a positive control group. Patients with asthma had mean APPS score of 9.66, compared to 9.85 for participants without asthma (P = .585). Subgroup analysis demonstrated similar findings among adults (P = .817) and adolescents (P = .585). Patients with a diagnosis of CF had significant sinus hypoplasia according to a mean APPS scores of 3.50 (P < .001). Sinus hypoplasia persisted in both adults (P < .001) and adolescents (P < .001) with CF. The presence of asthma is not associated with altered paranasal sinus pneumatization. In contrast, CF is associated with significantly reduced sinus pneumatization. These findings suggest that aberrant sinus pneumatization may not be a feature of asthma and that chronic mucosal respiratory disease is not a generalizable cause for altered paranasal sinus pneumatization.

Abstract
Allergic rhinitis (AR) is an IgE-mediated inflammatory disease of the nasal mucosa with well described local immune responses during allergen exposure. The frequent association of AR with general extra-nasal symptoms and other allergic conditions, such as conjunctivitis and asthma, however, support a more systemic disease impact. In addition to acute elevation of soluble inflammatory mediators in periphery blood, a growing number of studies have reported changes in circulating blood cells after specific nasal allergen challenge or environmental allergen exposure. These findings imply an involvement of specific blood leukocyte subsets, thrombocytes and recently, erythrocytes. This review summarizes the circulating blood cell dynamics associated with allergen exposure in AR subjects reported so far. Additionally, the impact of therapy, particularly allergen-specific immunotherapy (AIT), the only currently available causal treatment reducing AR-related symptoms, is further considered in this context.

Two inflammatory phenotypes of nasal polyps and comorbid asthma. Ann Allergy Asthma Immunol 2017; 118:318-325.

Abstract
BACKGROUND Nasal polyps and comorbid asthma (NPCA) is a common united airway disease. However, the inflammatory phenotyes of NPCA are not clear. OBJECTIVE To identify inflammatory phenotypes of NPCA. METHODS A total of 106 patients diagnosed with NPCA were recruited from rhinologic clinics. A combined method of biopsies from nasal polyps and fractional exhaled nitric oxide (FeNO) was used to explore inflammatory phenotyes of NPCA. Patients were evaluated with respect to clinical, functional, and inflammatory parameters. Clinical outcomes after medical treatment were also assessed. RESULTS Two distinct inflammatory phenotypes (eosinophilic [64.15%] and noneosinophilic phenotypes [35.85%]) were identified. Inflammatory patterns of upper and lower airways were consistent in NPCA. Patients with eosinophilic NPCA had a higher nasal polyps recurrence rate than did patients with noneosinophilic NPCA, a more severe asthma phenotype (P < .001), higher exhaled nitric oxide levels (P < .001), higher IgE levels (P < .001), higher Lund-Mackay scores (P < .05), and more blood eosinophilia (P < .001). In addition, eosinophilic NPCA was associated with worse pulmonary function and responded well to an 8-week course of medical treatment based on computed tomographic findings and the ratio of forced expiratory volume in 1 second to forced vital capacity. The total IgE concentration was a marker for eosinophilic NPCA (optimal cutoff, >55.5 kU/L; sensitivity, 86.2%; specificity, 85.4%). CONCLUSION Patients with NPCA had 2 inflammatory phenotypes with distinct clinical profiles. Total IgE is a marker of eosinophilic NPCA.

Abstract
BACKGROUND Rhinitis and asthma share similar immunopathological features. Rhinomanometry is an important test used to assess nasal function and spirometry is an important tool used in asthmatic children. The degree to which the readouts of these tests are correlated has yet to be established. We sought to clarify the relationship between rhinomanometry measurements, fractional exhaled nitric oxide (FeNO), and spirometric measurements in asthmatic children. METHODS Patients' inclusion criteria: age between 5 and 18 years, history of asthma with nasal symptoms, and no anatomical deformities. All participants underwent rhinomanometric evaluations and pulmonary function and FeNO tests. RESULTS Total 84 children were enrolled. By rhinomanometry, the degree of nasal obstruction was characterized as follows: (1) no obstruction in 33 children, (2) slight obstruction in 29 children, and (3) moderate obstruction in 22 children. FeNO was significantly lower in patients without obstruction than those with slight or moderate obstruction. Dividing patients according to ATS Clinical Practice Guidelines regarding FeNO, patients < 12 years with FeNO > 20 ppb had a lower total nasal airflow rate than those with FeNO < 20 ppb. Patients ≥ 12 years with FeNO > 25 ppb had a lower total nasal airflow rate than those with FeNO < 25 ppb. CONCLUSIONS Higher FeNO was associated with a lower nasal airflow and higher nasal resistance. This supports a relationship between upper and lower airway inflammation, as assessed by rhinomanometry and FeNO. The results suggest that rhinomanometry may be integrated as part of the functional assessment of asthma.

Abstract
BACKGROUND Allergic rhinitis, a known risk factor for asthma onset, often accompanies mouth breathing. Mouth breathing may bypass the protective function of the nose and is anecdotally considered to increase asthma morbidity. However, there is no epidemiological evidence that mouth breathing is independently associated with asthma morbidity and sensitization to allergens. In this study, we aimed to clarify the association between mouth breathing and asthma morbidity and allergic/eosinophilic inflammation, while considering the effect of allergic rhinitis. METHODS This community-based cohort study, the Nagahama Study, contained a self-reporting questionnaire on mouth breathing and medical history, blood tests, and pulmonary function testing. We enrolled 9804 general citizens of Nagahama City in the Shiga Prefecture, Japan. RESULTS Mouth breathing was reported by 17% of the population and was independently associated with asthma morbidity. The odds ratio for asthma morbidity was 1.85 (95% CI, 1.27-2.62) and 2.20 (95% CI, 1.72-2.80) in subjects with mouth breathing alone and allergic rhinitis alone, which additively increased to 4.09 (95% CI, 3.01-5.52) when mouth breathing and allergic rhinitis coexisted. Mouth breathing in nonasthmatics was a risk for house dust mite sensitization, higher blood eosinophil counts, and lower pulmonary function after adjusting for allergic rhinitis. CONCLUSION Mouth breathing may increase asthma morbidity, potentially through increased sensitization to inhaled allergens, which highlights the risk of mouth-bypass breathing in the 'one airway, one disease' concept. The risk of mouth breathing should be well recognized in subjects with allergic rhinitis and in the general population.

Abstract
BACKGROUND Asthma is a comorbid condition that may be seen by otolaryngic allergists when treating their patients with allergic rhinitis (AR). Often asthma is overlooked when aggressive treatment could prevent the development or progression of early disease. METHODS This article is a retrospective review of the current literature on asthma as a comorbidity of the unified airway. The unified airway and asthma are clearly defined. The epidemiology, morbidity, mortality, pathophysiologic mechanisms, and the chronicity of asthma are reviewed. RESULTS The otolaryngic allergist will become familiar the unified airway concept and the close relationships between AR, chronic rhinosinusitis, and asthma. CONCLUSION Otolaryngologists should be aware of the unified airway in order to most effectively treat their patients with AR. Knowledge of the close relationships between asthma and AR will help prevent progression of disease, identify early asthma, and improve the outcomes and quality of life for our patients.

Abstract
Chronic rhinitis involves inflammation of the upper airways. An association with comorbid conditions, such as rhinosinusitis, asthma, and chronic obstructive pulmonary disease, has been commonly observed in epidemiologic studies. The underlying pathogenesis of these disorders may be similar. Complications of rhinitis include sleep disturbances, learning impairment, and decreased quality of life. It is vital to recognize the complications of rhinitis so that treatment strategies can address rhinitis as well as its comorbidities and complications in a coordinated manner.

Abstract
BACKGROUND Epidemiological and clinical studies suggest a relationship between rhinitis and asthma. Upper and lower airways may be influenced by a common inflammatory process. OBJECTIVE This study aimed to investigate the relationships between rhinitis symptom scores, and both nasal and bronchial airflow among children with seasonal allergic rhinitis (SAR) by means of spirometric and rhinomanometric measurement during and outside the pollen season. METHODS Twenty-nine children with both seasonal allergic rhinitis and asthma (AR+A), 30 children with SAR and no asthma (AR) and 36 non-allergic healthy children were evaluated prospectively during and outside the pollen season. Symptom severity was evaluated using both total symptom score and visual analog score (VAS). All participants also received rhinomanometric evaluation and pulmonary function testing. RESULTS In children with SAR the median total nasal flow, FEV1, FEF25-75 values were lower than control group during pollen season (p=0.01, p<0.001 and p<0.001 respectively). They had also higher total nasal resistance compared with control groups (p=0.01). Nasal symptom scores were higher among patients with concurrent asthma than patients who had only SAR out of pollen season (p<0.001). There was no significant difference between SAR participants with or without asthma and control group in terms of total nasal flow and total nasal resistance measured out of season (p=0.105 and p=0.19). FEF25-75 values of patients with and without asthma were significantly lower than those of controls out of season (p=0.022, p<0.001 respectively). CONCLUSION Our data suggests that as the presence of AR worsens asthma control, the presence of asthma may worsen symptoms of AR out of pollen season. We found that total nasal flow, FEV1, FEF25-75 values of patients with SAR were lower than those of controls out of season. FEF25-75 values of patients with asthma and without asthma were significantly lower than those of controls out of season. Thus, a careful evaluation of lower airways should be performed in even patients with seasonal allergic rhinitis alone.

Abstract
PURPOSE OF REVIEW To review the recent insights regarding the epidemiology of adult chronic rhinosinusitis (CRS), with particular attention to its association with other premorbid conditions. Identifying premorbid disease associations establishes potential risk factors for developing CRS and helps corroborate current postulates of the various pathophysiologic mechanisms involved with the development and persistence of paranasal sinus inflammation. RECENT FINDINGS Recent findings demonstrate that the diagnosis of CRS is associated with a higher premorbid prevalence of upper airway diseases, lower airway diseases, gastroesophageal reflux disease, diseases of epithelial tissues, autoimmune disorders, and psychiatric conditions. Although some of these conditions have long been associated with CRS, improvements in study design and future studies in the general population will more accurately estimate the relative strengths of associations, clinical relevance, and temporal relationship of these various conditions in relation to the development of CRS. SUMMARY The predisposing patterns of premorbid illnesses may provide valuable information regarding the underlying causes of CRS and allow for both therapeutic and preventive interventions. There remains conflicting evidence within the literature regarding the association of CRS with some medical conditions, signifying the need for continued research on the subject. Limitations of the current studies include small sample sizes, lack of prospective longitudinal or interventional studies that help establish causality, and variable criteria for diagnosis of CRS in the outpatient setting.

Abstract
BACKGROUND The upper (UAW) and lower (LAW) airways of patients with cystic fibrosis (CF) have the same ion-channel defects, but little is known about similarities and differences in host immunological responses at the two levels. AIM Identification and comparison of both levels' pathogen colonization and resulting immunological host responses. METHODS The UAW and LAW of 40 CF patients were non-invasively assessed by nasal lavage and induced sputum. Pathogen colonization, cytology, and the concentrations of inflammatory mediators (TNF-α, MPO, matrix metalloprotease (MMP)-9, tissue inhibitor of metalloprotease (TIMP)-1, regulated upon activation, normal T-cell expressed and presumably secreted (RANTES), and interleukin (IL)-1β, -5, -6, -8, and -10) were measured. RESULTS Inflammatory responses were more pronounced in the LAW than the UAW. Pseudomonas aeruginosa LAW colonization is accompanied by a significantly enhanced neutrophil (PMN)-dominated response (P = 0.041) and IL-8 concentration (P = 0.01) not observed in P. aeruginosa UAW colonization. In contrast, sinonasal P. aeruginosa colonization resulted in elevated RANTES (P = 0.039) and reduced MMP-9 (P = 0.023) and TIMP-1 (P = 0.035) concentrations. Interestingly, LAW P. aeruginosa colonization was associated with reduced sinonasal concentrations of MMP-9 (P = 0.01) and TIMP-1 (P = 0.02), a finding independent of UAW colonization for MMP-9. CONCLUSION CF UAW and LAW show distinct inflammatory profiles and differentiated responses upon P. aeruginosa colonization. Assessment of UAW colonization and MMP-9 are predictive of chronic pulmonary colonization with P. aeruginosa. Thus, this linkage between CF UAW and LAW can provide new clinical and scientific implications.

Abstract
BACKGROUND Symptom scoring for the assessment of allergen immunotherapy is associated with a substantial placebo effect. OBJECTIVE To assess the ability of exhaled breath temperature (EBT), a putative marker of airway inflammation, to evaluate objectively the efficacy of grass pollen sublingual immunotherapy in a proof-of-concept study. METHODS This was a double-blinded, placebo-controlled clinical trial in 56 subjects (mean ± SD 30 ± 12 years old, 33 men) sensitized to grass pollen. The objective measurements were EBT, spirometry, and periostin and high-sensitivity C-reactive protein in blood. Overall discomfort scored on a visual analog scale was used as a proxy for subjective symptoms. Evaluations were performed before, during, and after the grass pollen season. RESULTS Fifty-one subjects (25 and 26 in the active treatment and placebo groups, respectively) were assessed before and during the pollen season. The mean pre- vs in-season increase in EBT was significantly smaller (by 59.1%) in the active treatment than in the placebo group (P = .030). Of the other objective markers, only the blood periostin level increased significantly during the pollen season (P = .047), but without intergroup differences. Subjectively, the mean pre- vs in-season increase in the visual analog scale score was 32.3% smaller in the active treatment than in the placebo group, although this difference did not reach statistical significance (P = .116). CONCLUSION These results suggest that the efficacy of grass pollen sublingual immunotherapy can be assessed by EBT, a putative quantitative measurement of airway inflammation, which is superior in its power to discriminate between active and placebo treatment than a subjective assessment of symptoms assessed on a visual analog scale.

Abstract
CONCLUSION Early intervention may change the natural course of allergic rhinitis, preventing the progression to asthma. In particular, immunotherapy guarantees remission of local symptoms and valid protection against local and bronchial complications. Symptomatic treatment represents a valid alternative; it is always to be preferred to abstention from any treatment. OBJECTIVES Data emerging from various studies on the increase of the prevalence of allergic rhinitis in recent decades appear to be widely dishomogeneous. Another point that needs clarification is the relationship between allergic rhinitis and lower airways pathologies such as asthma or bronchitis. METHODS We followed the evolution of allergic rhinitis in a group of patients for the last 30 years to highlight the efficacy of different treatments in the prevention of complications, specifically asthma. After 32 years (1980-2012), 46/73 (63%) patients completed the follow-up. RESULTS Symptomatic drugs exhibited maximum efficacy from the third to the eighth year, with 13 of 15 patients reporting an improvement of symptoms; immunotherapy achieved the best efficacy starting from the sixth to the tenth year (8 of 10 patients recovered). Subsequently, improvements decreased in the two groups, to a steady level of 11 of 15 and 6 of 10 recovered patients. Asthma developed in 3 of 46 patients and only among patients that were not treated.

Abstract
OBJECTIVE Our objective was to assess the oxidative stress status and analyse the relationship between an oxidant/antioxidant imbalance and the mediator release properties of cord blood basophils from neonates born to mothers with atopic asthma. METHODS Cord blood was collected from the neonates of 16 asthmatic mothers and 18 healthy mothers Basophils were purified and stimulated by Dermatophagoides farinae (Df), hyperosmotic mannitol or peptidoglycan (PGN). Immunoblotting detected nuclear factor κB (NFκB) as a measure of functional receptor response. The linear correlations between IL-4 levels in the supernatants and 3-nitrotyrosine (3-NT), glutathione peroxidase (GSH-Px) in the serum were evaluated. RESULTS Compared with the healthy group, the levels of 3-NT in maternal blood and cord blood were significantly higher in allergic asthma group, whereas the GSH-Px activity were lower. After stimulation, cord blood basophils from the neonates born to atopic mothers produced more IL-4 involving NF-κB pathways. There was a significant relationship between the IL-4 levels produced by basophils and 3-NT (or GSH-Px) in cord blood from allergic asthma group. CONCLUSION In asthma, mediator release properties of human basophils induced by environmental allergens and irritants are associated with oxidative stress, which may be one of the pathogenesis of allergic diseases.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a prevalent condition with underexplored risk factors. OBJECTIVES We sought to determine CRS incidence and evaluate associations with a range of premorbid medical conditions for chronic rhinosinusitis without nasal polyps (CRSsNP) and chronic rhinosinusitis with nasal polyps (CRSwNP) using real-world clinical practice data. METHODS Electronic health records data from 446,480 Geisinger Clinic primary care patients were used for a retrospective longitudinal cohort study for data from 2001-2010. By using logistic regression, newly diagnosed CRS cases between 2007 and 2009 were compared with frequency-matched control subjects on premorbid factors in the immediate (0-6 months), intermediate (7-24 months), and entire observed timeframes before diagnosis. RESULTS The average incidence of CRS was 83 ± 13 CRSwNP cases per 100,000 person-years and 1048 ± 78 CRSsNP cases per 100,000 person-years. Between 2007 and 2009, 595 patients with incident CRSwNP and 7523 patients with incident CRSsNP were identified and compared with 8118 control subjects. Compared with control subjects and patients with CRSsNP, patients with CRSwNP were older and more likely to be male. Before diagnosis, patients with CRS had a higher prevalence of acute rhinosinusitis, allergic rhinitis, chronic rhinitis, asthma, gastroesophageal reflux disease, adenotonsillitis, sleep apnea, anxiety, and headaches (all P < .001). Patients with CRSsNP had a higher premorbid prevalence of infections of the upper and lower airway, skin/soft tissue, and urinary tract (all P < .001). In the immediate and intermediate timeframes analyzed, patients with CRS had more outpatient encounters and antibiotic prescriptions (P < .001), but guideline-recommended diagnostic testing was performed in a minority of cases. CONCLUSIONS Patients who are given a diagnosis of CRS have a higher premorbid prevalence of anxiety, headaches, gastroesophageal reflux disease, sleep apnea, and infections of the respiratory system and some nonrespiratory sites, which results in higher antibiotic, corticosteroid, and health care use. The use of guideline-recommended diagnostic testing for confirmation of CRS remains poor.

Abstract
Morbidity from allergic diseases is increasing. Basophils play a critical role in systemic anaphylaxis and chronic allergic inflammation. The prenatal environment must be regarded as a possible early risk factor for allergic diseases in children. Our objective was to determine if basophils harvested from neonates genetically predisposed to atopic disease had different levels of CD63 expression and IL-4 release properties in response to various stimuli (peptidoglycan, Dermatophagoides farinae, hyperosmotic mannitol). Blood samples were collected from 16 asthmatic and 18 healthy women and their newborns. Peripheral blood basophil histamine was measured using the human basophil degranulation test (HBDT), whereas activation was assessed by flow cytometric measurement of CD63 expression on the cord blood basophil surface. IL-4 levels were quantified by ELISA following allergen stimulation. The basophil degranulation index (DI) in granulocytes harvested from the peripheral blood of asthmatic women was assessed following stimulation with peptidoglycan (PGN), Dermatophagoides farinae (Df ) extract, or hyperosmotic mannitol. The DI was significantly higher in atopic women than in healthy controls. Upregulation of CD63 on the cord blood basophil surface was also detected in response to these stimuli. Basophils purified from the cord blood of neonates born to atopic mothers produced more IL-4 compared to basophils purified from the controls. These data suggested that various stimuli play a role in augmenting allergic reactions via modulation of activated basophil cytokine secretion. It may require new methods to stabilize the basophils in allergic diseases.

Abstract
The upper and lower respiratory tracts function as an interdependent physiologic mechanism, and stimuli that trigger pathophysiologic changes in one portion of the airway can provoke similar changes throughout the airway. The unified airway model acknowledges these shared airway features, suggesting the importance of comprehensive evaluation of patients with any respiratory symptoms. Two areas are of specific importance to the septoplasty/rhinoplasty surgeon: (1) preoperative evaluation of the patient with rhinitis undergoing nasal surgery, and (2) perioperative and postoperative management of the nose. Management of potential cardiopulmonary risks among susceptible individuals is vital in the perioperative management of these patients.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyposis (CRSwNP) represents an interesting model to investigate the existence of a non-allergic unified airway. The factors associated with airway dysfunction in CRSwNP are not fully understood. OBJECTIVE To assess the impact of nasal disease on lower airway dysfunction in CRSwNP. METHODS Fifty-seven patients with CRSwNP underwent spirometry, nasal endoscopy, exhaled nitric oxide, methacholine bronchial challenge, blood sampling for total IgE, eosinophil count and radioallergosorbent testing (NCT00788749). Three phenotypic groups were identified: 'asthma group' (asthma diagnosis); 'inflammatory group' [no asthma diagnosis, but elevated fractionated exhaled nitric oxide (FE(NO)) and/or bronchial-hyperreactivity (BHR)]; and 'non-inflammatory group' (no asthma diagnosis, no BHR and normal FE(NO)). Group comparisons, univariate and multivariate analyses were performed to examine associations with airway dysfunction. RESULTS FEV(1) and FEF(25-75%) were reduced in asthma, but there was no difference between the non-asthmatic groups. Total IgE and eosinophils were elevated in asthma vs. the non-inflammatory group, but there was no difference for asthma vs. inflammatory groups. BHR was the only significant predictor of FEV(1) (P<0.001). For FEF(25-75), BHR and eosinophil count were independent predictors (P<0.001 and P=0.04). Nasal outcomes were not predictors of spirometry. CONCLUSION AND CLINICAL RELEVANCE In CRSwNP there is asymptomatic airway dysfunction suggestive of an asthmatic phenotype. Impairment of lung function is significantly associated with BHR and eosinophilia but not parameters of nasal disease suggesting that severity of airway dysfunction relates to the spectrum of asthma rather than rhinosinusitis. Lower airway dysfunction is common in CRSwNP but does not correlate to the severity of nasal disease. Signs and symptoms of asthma should be sought and treated in CRSwNP.

Abstract
BACKGROUND Allergic rhinitis (AR), the most common chronic allergic condition in outpatient medicine, is associated with immense health care costs and socioeconomic consequences. AR's impact may be partly from interacting of respiratory conditions via allergic inflammation. This study was designed to review potential interactive mechanisms of AR and associated conditions and consider the relevance of a bidirectional "unified airway" respiratory inflammation model on diagnosis and treatment of inflammatory airway disease. METHODS MEDLINE was searched for pathophysiology and pathophysiological and epidemiologic links between AR and diseases of the sinuses, lungs, middle ear, and nasopharynx. RESULTS Allergic-related inflammatory responses or neural and systemic processes fostering inflammatory changes distant from initial allergen provocation may link AR and comorbidities. Treating AR may benefit associated respiratory tract comorbidities. Besides improving AR outcomes, treatment inhibiting eosinophil recruitment and migration, normalizing cytokine profiles, and reducing asthma-associated health care use in atopic subjects would likely ameliorate other upper airway diseases such as acute rhinosinusitis, chronic rhinosinusitis (CRS) with nasal polyposis (NP), adenoidal hypertrophy, and otitis media with effusion. CONCLUSION Epidemiological concordance of AR with several airway diseases conforms to a bidirectional "unified airway" respiratory inflammation model based on anatomic and histological upper and lower airway connections. Epidemiology and current understanding of inflammatory, humoral, and neural processes make links between AR and disorders including asthma, otitis media, NP, and CRS plausible. Combining AR with associated conditions increases disease burden; worsened associated illness may accompany worsened AR. AR pharmacotherapies include antihistamines, leukotriene antagonists, intranasal corticosteroids, and immunotherapy; treatments attenuating proinflammatory responses may also benefit associated conditions.

Abstract
This document provides healthcare practitioners with information regarding the management of acute rhinosinusitis (ARS) and chronic rhinosinusitis (CRS) to enable them to better meet the needs of this patient population. These guidelines describe controversies in the management of acute bacterial rhinosinusitis (ABRS) and include recommendations that take into account changes in the bacteriologic landscape. Recent guidelines in ABRS have been released by American and European groups as recently as 2007, but these are either limited in their coverage of the subject of CRS, do not follow an evidence-based strategy, or omit relevant stakeholders in guidelines development, and do not address the particulars of the Canadian healthcare environment. Advances in understanding the pathophysiology of CRS, along with the development of appropriate therapeutic strategies, have improved outcomes for patients with CRS. CRS now affects large numbers of patients globally and primary care practitioners are confronted by this disease on a daily basis. Although initially considered a chronic bacterial infection, CRS is now recognized as having multiple distinct components (eg, infection, inflammation), which have led to changes in therapeutic approaches (eg, increased use of corticosteroids). The role of bacteria in the persistence of chronic infections, and the roles of surgical and medical management are evolving. Although evidence is limited, guidance for managing patients with CRS would help practitioners less experienced in this area offer rational care. It is no longer reasonable to manage CRS as a prolonged version of ARS, but rather, specific therapeutic strategies adapted to pathogenesis must be developed and diffused. Guidelines must take into account all available evidence and incorporate these in an unbiased fashion into management recommendations based on the quality of evidence, therapeutic benefit, and risks incurred. This document is focused on readability rather than completeness, yet covers relevant information, offers summaries of areas where considerable evidence exists, and provides recommendations with an assessment of strength of the evidence base and degree of endorsement by the multidisciplinary expert group preparing the document. These guidelines have been copublished in both Allergy, Asthma & Clinical Immunology and the Journal of Otolaryngology-Head and Neck Surgery.

Abstract
BACKGROUND Several clinical and experimental observations suggest that allergen deposition in the nose may partially be responsible for the induction of conjunctival symptoms in allergic rhinitis. The aims of this study were to evaluate the induction of conjunctival symptoms by selective nasal allergen provocation and to assess the feasibility of the different tools for evaluation of conjunctival allergic inflammation. METHODS Grass pollen allergic subjects with rhinoconjunctivitis symptoms during the pollen season (n = 12) underwent a nasal sham and grass pollen provocation extra-seasonally. Nasal and conjunctival symptoms were scored using the Visual Analogue Scale (VAS) system at baseline, 15 min, 1 h and 24 h after provocation. In addition to Peak Nasal Inspiratory flow (PNIF) measurements, conjunctival inflammation and vascular congestion were evaluated and histamine and substance P levels in tear fluid were measured. RESULTS Selective nasal grass pollen provocation induced ocular pruritus, lacrimation and conjunctival vascular congestion. PNIF values correlated inversely with lacrimation (r = -0.71, P < 0.001) and ocular pruritus (r = -0.41, P < 0.05). Four out of 11 patients showed a conjunctival eosinophilic inflammation and levels of histamine (r = 0.73, P < 0.05) and substance P (r = 0.67, P = 0.05) in tear fluid correlated with conjunctival symptoms. CONCLUSION Selective nasal grass pollen provocation induced conjunctival inflammation, ocular pruritus and lacrimation, which correlated with histamine and substance P levels in tear fluid and inversely with the PNIF values. These data show a naso-ocular interaction in allergic rhinitis and offer objective tools for evaluation of conjunctival inflammation in allergic rhinoconjunctivitis.

Abstract
Besides the anatomic continuity of the upper and lower airways, inflammation in one part of the airway influences the homeostasis of the other. The mechanisms underlying this interaction have been studied primarily in allergic disease, showing systemic immune activation, induction of inflammation at a distance, and a negative impact of nasal inflammation on bronchial homeostasis. In addition to allergy, other inflammatory conditions of the upper airways are associated with lower airway disease. Rhinosinusitis is frequently associated with asthma and chronic obstructive pulmonary disease. The impairment of purification, humidification, and warming up of the inspired air by the nose in rhinosinusitis may be responsible in part for bronchial pathology. The resolution of sinonasal inflammation via medical and/or surgical treatment is responsible for the beneficial effect of the treatment on bronchial disease. This article provides a comprehensive overview of the current knowledge of upper and lower airway communication beyond allergic disease.

Abstract
Although the concept of "global airway allergy" has become widely accepted during recent years, nasobronchial interaction and its mechanisms remain incompletely understood. The experimental study of the effect of nasal allergen deposition on lower airway pathology is hampered by the difficulty of avoiding lower airway penetration of the allergens. In ovalbumin-sensitized mice with experimental airway allergy, nasal allergen provocations were performed after complete anatomical separation of upper and lower airways by means of a tracheotomy. A canula was inserted in the trachea, and the trachea was ligated, thus inhibiting any passage of allergens from upper to lower airways. Mice showed bronchial hyperresponsiveness to methacholine as early as 4 hours after nasal allergen provocation in the absence of recruitment of inflammatory cells. An increased substance P (SP) concentration in the bronchial lumen was found, as well as an increased number of SP-positive pulmonary nerves. Treatment with a neurokinin (NK) 1 receptor antagonist abolished the allergen-induced bronchial hyperresponsiveness. Moreover, endobronchial administration of SP caused NK1 receptor-dependent bronchial hyperresponsiveness in mice with airway allergy. Nasal allergen provocation rapidly induces bronchial hyperresponsiveness via pulmonary up-regulation of SP and activation of NK1 receptors.

Abstract
The interaction between upper and lower airway disease has been recognized for centuries, with recent studies showing a direct link between upper and airway inflammation in allergic patients. The mechanisms underlying the interaction between nasal and bronchial inflammation have primarily been studied in allergic disease, showing systemic immune activation after allergen inhalation, induction of inflammation at a distance, and a negative impact of nasal inflammation on bronchial homeostasis. Therefore, allergic rhinitis and asthma are considered part of the global airway allergy syndrome. Besides allergy, other inflammatory conditions such as the common cold, acute rhinosinusitis, and chronic rhinosinusitis are associated with lower airway disease. Chronic sinus disease with or without nasal polyps are frequently found in patients with asthma and chronic obstructive pulmonary disease with improvement of bronchial symptoms and respiratory function by adequate medical and surgical therapy for rhinosinusitis. The resolution of sinonasal inflammation and hence sinonasal functions by medical or surgical treatment is considered responsible for the beneficial effect of treatment on bronchial disease. This article aims at providing a comprehensive overview of the current knowledge on the interaction between common cold, acute and chronic rhinosinusitis, and lower airway biology.

Abstract
PURPOSE OF REVIEW This article reviews recent literature on the important relationship between the nose, paranasal sinuses and lungs. Recent advances in the understanding of the pathophysiological mechanisms underlying the association between upper and lower airways are discussed. RECENT FINDINGS Epidemiological, clinical, and immunopathological data demonstrate an important link between upper and lower airways beyond the well recognized association of allergic rhinitis and asthma. Other upper airway diseases including occupational rhinitis, chronic rhinosinusitis, nasal polyposis with or without aspirin sensitivity, and obstructive sleep apnea have all been linked to asthma and/or asthma severity, as well as other lower airway diseases. Although the underlying mechanisms to explain these associations are unclear, recent work suggests the presence of systemic inflammation triggered by both the adaptive and innate immune system as a major driving force in combined airway diseases. SUMMARY Epidemiological data, clinical observations, and immunopathological studies demonstrate an important link between upper and lower airways. An understanding of how the upper airway impacts on lower airway disease has important diagnostic, therapeutic and prognostic implications.

Abstract
Current national and international asthma guidelines recommend treatment of children with asthma towards achieving and maintaining asthma control. These guidelines provide more stringent recommendations to increase therapy for patients with uncontrolled asthma in order to reduce asthma-related morbidity and mortality. Newer combination agents such as budesonide and formoterol have been shown to be safe and effective in treatment of asthma in children. Use of long-term controller agents like this in combination with improved compliance and treatment of co-morbid conditions have been successful in this endeavor. This review discusses control of pediatric asthma with focus on the use of budesonide in combination with formoterol.

Abstract
Substantial evidence exists to support the concept that the respiratory system functions as an integrated unit. Pathophysiological processes that involve the upper airway generally occur in conjunction with lower airway diseases, and diffuse inflammation often affects mucosal surfaces of the middle ear, nose, sinuses, and tracheobronchial tree simultaneously. Support for this relationship can be found in epidemiological studies, in shared pathophysiological mechanisms, and in observed interactive treatment effects. This model and its implications are discussed.
