Abstract
BACKGROUND Large epidemiologic studies have suggested that a history of tobacco use may be associated with an increased risk of developing chronic rhinosinusitis (CRS). The impact of tobacco use on revision rates of endoscopic sinus surgery (ESS), however, remains limited. OBJECTIVE This study seeks to define the independent risk of tobacco use (active or prior) on revision rates of ESS among a large cohort of patients with CRS. METHODS A state population database was queried for patients age ≥18 years with CRS who underwent at least one ESS between 1996 and 2018. Demographic characteristics, history of ESS, and tobacco use status were compared across patients with CRS, using t tests for continuous variables and χ2 tests for categorical variables. Unadjusted and adjusted logistic regression models were used to understand the impact of tobacco status on revision surgery. RESULTS The final analysis included 34 350 patients (29 916 CRS with no revision surgery and 4434 CRS with revision surgery). Unadjusted regression analysis demonstrated an increased odds of undergoing revision ESS (OR 1.12, 95% CI: 1.00-1.25, P = .05) among males with a history of tobacco use and CRS. Adjusted regression analysis demonstrated that the risk of revision ESS among CRS patients with a history of asthma and tobacco use was 1.72-fold, while the risk among CRS patients who were tobacco users without asthma was 1.11-fold. CONCLUSION History of tobacco use is an independent risk factor for revision ESS among patients with CRS.

Abstract
Chronic rhinosinusitis (CRS) is a public health problem that has a significant socio-economic impact. Moreover, the complexity of this disease due to its heterogeneous nature based on the underlying pathophysiology - leading to different disease variants - further complicates our understanding and directions for the most appropriate targeted treatment strategies. Several International/national guidelines/position papers and/or consensus documents are available that present the current knowledge and treatment strategies for CRS. Yet there are many challenges to the management of CRS especially in the case of the more severe and refractory forms of disease. Therefore, the International Collaboration in Asthma, Allergy and Immunology (iCAALL), a collaboration between EAACI, AAAAI, ACAAI, and WAO, has decided to propose an International Consensus (ICON) on Chronic Rhinosinusitis. The purpose of this ICON on CRS is to highlight the key common messages from the existing guidelines, the differences in recommendations as well as the gaps in our current knowledge of CRS, thus providing a concise reference. In this document we discuss the definition of the disease, its relevance, pharmacoeconomics, pathophysiology, phenotypes and endotypes, genetics and risk factors, natural history and co-morbidities as well as clinical manifestations and treatment options in both adults and children comprising pharmacotherapy, surgical interventions and more recent biological approaches. Finally, we have also highlighted the unmet needs that wait to be addressed through future research.

Abstract
OBJECTIVES/HYPOTHESIS To evaluate sleep quality in patients with chronic rhinosinusitis (CRS) using a validated outcome measure and to compare measures of CRS disease severity with sleep dysfunction. STUDY DESIGN Cross-sectional evaluation of a multi-center cohort. METHODS According to the 2007 Adult Sinusitis Guidelines, patients with CRS were prospectively enrolled from four academic, tertiary care centers across North America. Each subject completed the Pittsburgh Sleep Quality Index (PSQI) instrument, in addition to CRS-specific measures of quality-of-life (QOL), endoscopy, computed tomography (CT), and olfaction. Patient demographics, comorbid conditions, and clinical measures of disease severity were compared between patients with "good" (PSQI; ≤5) and "poor" (PSQI; > 5) sleep quality. RESULTS Patients (n = 268) reported a mean PSQI score of 9.4 (range: 0-21). Seventy-five percent of patients reported PSQI scores above the traditional cutoff, indicating poor sleep quality. Patients with poor sleep quality were found to have significantly worse QOL scores on both the Rhinosinusitis Disability Index (P < 0.001) and 22-item Sinonasal Outcome Test (P < 0.001). No significant differences in average endoscopy, CT, or olfactory function scores were found between patients with good or poor sleep quality. Tobacco smokers reported worse average PSQI total scores compared to nonsmokers (P = 0.030). Patients reporting poor sleep were more likely to have a history of depression, even after controlling for gender (P = 0.020). CONCLUSION The majority of patients with CRS have a poor quality of sleep, as measured by the PSQI survey. Poor sleep quality is significantly associated with CRS-specific QOL, gender, comorbid depression, and tobacco use, but not CT score or endoscopy grade. LEVEL OF EVIDENCE 2b.

Abstract
PURPOSE OF REVIEW To review the current knowledge of the pathophysiology, epidemiology, and management of environmental pollutants and allergic rhinitis. RECENT FINDINGS Both active cigarette smoking and passive exposure to cigarette smoke are associated with chronic rhinitis and sinusitis. Matrix metalloproteinase 9, which is thought to contribute to the pathophysiology of allergy, is elevated in children with passive cigarette smoke exposure compared with controls. Ground-level ozone and particulate matter exposure is associated with an allergic-type response and may increase sensitization to other allergens. Certain occupational exposures can cause nasal irritation and local cytotoxic effects. Evidence suggests that rhinitis symptomatology may often precede the development of occupational asthma. SUMMARY Environmental factors have been noted to induce sinonasal mucosal irritation and often contribute to the multifactorial cause of chronic rhinitis and allergic rhinitis. Cigarette smoke is a common irritant that impacts the innate immune function of the sinonasal epithelial cells, and creates local irritation and cytotoxic effects. Both active smoking and exposure to second-hand smoke increase the risk of chronic rhinitis. Many other environmental pollutants are associated with chronic rhinitis, including ozone, particulate matter, and occupational irritants. The management of chronic rhinitis associated with environmental exposures is similar to the management of other types of chronic rhinitis. Although often not feasible, avoidance is probably the most effective course.

Abstract
The aim of this study was to assess the effects of short exposures to experimentally aged cigarette smoke on the nose and upper airways. This crossover study compared the effects of 30-min exposures to (1) experimentally aged cigarette smoke at 1 mg/m³ particulate matter (PM)/14 ppm carbon monoxide (CO) and (2) conditioned filtered air on urinary metabolites of nicotine and tobacco-specific nitrosamines. Subjective nasal symptoms were assessed by questionnaire, objective nasal congestion was assessed by anterior rhinomanometry and nasal nitric oxide (NO) concentrations were determined. Experimentally aged cigarette smoke is a validated model for secondhand smoke (SHS). Twenty-six healthy nonsmokers (10 normal, 7 atopic/nonrhinitic, 7 atopic rhinitic, 2 nonatopic/rhinitic) were studied. A 30-min exposure to SHS increased nasal resistance in healthy nonsmokers. The rise in nasal resistance was most pronounced in rhinitic subjects. Significant increases were not noted when atopic subjects were considered independent of rhinitis status. Secondhand smoke exposure also elevated subjective nasal symptoms and urinary concentrations of metabolites of nicotine (cotinine and trans-3´-hydroxycotinine) and tobacco-specific nitrosamines [(4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL)] in all subgroups of subjects. Exposure-related, subjective nasal symptoms were significantly higher in rhinitic than in normal subjects. Significant changes in nasal NO concentrations were not detected. Data indicate a 30-min exposure to secondhand smoke at 1 mg/m³ PM increases subjective upper respiratory symptoms, increases urinary cotinine and NNAL, and produces objective nasal airflow obstruction in human subjects.

Abstract
BACKGROUND Environmental factors such as inhaled pollutants like cigarette smoke may play a significant role in diseases of the upper airway including chronic rhinosinusitis (CRS). The objectives of this review are to summarize prior studies that describe the correlation between active smoking and secondhand smoke (SHS) on CRS. We also review the pathophysiologic effects of cigarette smoke on sinonasal mucosa and discuss its impact on surgical outcomes of endoscopic sinus surgery (ESS). METHODS A literature search was conducted of the PubMed database using the terms "sinusitis" or "rhinosinusitis" and "smoking." Additional search terms of "nasal epithelial" and "smoke" were used to find articles that discussed pathophysiologic effects of tobacco smoke, whereas "secondhand smoke" was added to identify articles analyzing the correlation of SHS and CRS. Finally "endoscopic sinus surgery" and "outcomes" were linked to "smoking" to find articles that analyzed the impact of smoking on surgical results. RESULTS We identified 204 articles in the initial search. An additional 72 articles were reviewed for their relevance to the pathophysiologic effects of tobacco smoke while 31 articles were analyzed to determine the correlation of SHS and CRS. Twenty-nine articles were reviewed to analyze the impact of smoking on surgical results. CONCLUSION There is clear evidence in the literature that cigarette smoke, either through active smoking or passive exposure to SHS, contributes to CRS. Recent prospective studies suggest that active smoking is not a contraindication to ESS, whereas the impact of smoking volume and long-term smoking after ESS has not been sufficiently evaluated.

Abstract
OBJECTIVE To assess the influence of environmental exposure to tobacco smoke on the nasal symptoms and nasal resistance of young patients with perennial allergic rhinitis. DESIGN Cross-sectional study. SETTING Tertiary referral centre. PARTICIPANTS Fifty patients were evaluated (aged 10-19 years old): 25 patients with and 25 patients without recent exposure to tobacco smoke (confirmed by cotinine/creatinine ratio). MAIN OUTCOMES MEASURES After a clinical evaluation, all the patients replied to a validated questionnaire of the severity of the nasal symptoms. Then total nasal airway resistance was recorded by active anterior rhinomanometry. RESULTS Patients with exposure to tobacco smoke had a larger total resistance than patients without exposure (t-test, P < 0.01). No significant correlation was observed between the total score of the questionnaire of nasal symptoms and the nasal resistance. CONCLUSIONS In young patients with perennial allergic rhinitis, exposure to tobacco smoke can be related to increased nasal resistance, which may not be recognised by the report of nasal symptoms.

Abstract
PURPOSE OF REVIEW This review critically evaluates the existing biological evidence regarding the immediate and short-term respiratory consequences of secondhand smoke (SHS). RECENT FINDINGS A 1-h exposure to SHS at bar/restaurant levels generates a marked inflammatory reaction and significant decrements on lung function. These deleterious effects of SHS are exacerbated when physical activity follows the SHS exposure, particularly in less fit individuals. The main respiratory effect mechanisms of SHS include a direct induction of growth factors resulting in airway remodelling and alterations in nitric oxide regulation. Pharmacological agents that increase either apical membrane chloride conductance or basolateral membrane potassium conductance may be of therapeutic benefit in patients with diseases related to SHS exposure. Moreover, treatment with statins has shown beneficial effects towards preventing the SHS-induced pulmonary hypertension, vascular remodelling, and endothelial dysfunction. SUMMARY Based on recently discovered evidence, even brief and short-term exposures to SHS generate significant adverse effects on the human respiratory system. Future research directions in this area include the concentrations of tobacco smoke constituents in the alveolar milieu following SHS exposure, individual susceptibility to SHS, as well as pharmacological treatments for reversing the SHS-induced airway remodelling.

Abstract
CONTEXT Despite progress in tobacco control, secondhand smoke (SHS) exposure remains prevalent worldwide and is implicated in the initiation and maintenance of cigarette smoking. OBJECTIVE To determine whether moderate SHS exposure results in brain α(4)β(2)* nicotinic acetylcholine receptor (nAChR) occupancy. DESIGN, SETTING, AND PARTICIPANTS Positron emission tomography scanning and the radiotracer 2-[18F]fluoro-3-(2(S)azetidinylmethoxy) pyridine (also known as 2-[(18)F]fluoro-A-85380, or 2-FA) were used to determine α(4)β(2)* nAChR occupancy from SHS exposure in 24 young adult participants (11 moderately dependent cigarette smokers and 13 nonsmokers). Participants underwent two bolus-plus-continuous-infusion 2-FA positron emission tomography scanning sessions during which they sat in the passenger's seat of a car for 1 hour and either were exposed to moderate SHS or had no SHS exposure. The study took place at an academic positron emission tomography center. Main Outcome Measure Changes induced by SHS in 2-FA specific binding volume of distribution as a measure of α(4)β(2)* nAChR occupancy. RESULTS An overall multivariate analysis of variance using specific binding volume of distribution values revealed a significant main effect of condition (SHS vs control) (F(1,22) = 42.5, P < .001) but no between-group (smoker vs nonsmoker) effect. Exposure to SHS led to a mean 19% occupancy of brain α(4)β(2)* nAChRs (1-sample t test, 2-tailed, P < .001). Smokers had both a mean 23% increase in craving with SHS exposure and a correlation between thalamic α(4)β(2)* nAChR occupancy and craving alleviation with subsequent cigarette smoking (Spearman ρ = -0.74, P = .01). CONCLUSIONS Nicotine from SHS exposure results in substantial brain α(4)β(2)* nAChR occupancy in smokers and nonsmokers. Study findings suggest that such exposure delivers a priming dose of nicotine to the brain that contributes to continued cigarette use in smokers. This study has implications for both biological research into the link between SHS exposure and cigarette use and public policy regarding the need to limit SHS exposure in cars and other enclosed spaces.

Abstract
BACKGROUND Rhinosinusitis is a costly disease that adversely affects quality of life (QOL). It is known to be influenced by environmental factors, but few studies have evaluated the association between secondhand tobacco smoke (SHS) exposure and chronic rhinosinusitis (CRS). To address this evidence gap, we evaluated the association of SHS and CRS risk in a community-based case-control study of adult nonsmokers. METHODS In Washington County, MD, 100 cases with a confirmed diagnosis of CRS and 100 controls matched for age, sex, and smoking status (former-never) were recruited and interviewed. A validated questionnaire was used to assess past and present SHS exposure as well as disease-specific QOL. RESULTS Compared with those who reported no SHS exposure, current or childhood SHS exposure was associated with significantly increased risk of CRS (odds ratio, 2.33; 95% CI, 1.02, 5.34). CRS cases exposed to SHS (n = 39) had worse mean scores in nasal obstruction/blockage (3.1 versus 2.5; p = 0.02), nasal discharge (3.3 versus 2.7; p = 0.03), headaches (2.4 versus 1.5; p = 0.01), and cough (2.1 versus 1.5; p = 0.04) than cases without SHS exposure (n = 61). Cases exposed to SHS were also more likely to use nasal decongestants (53.9% versus 34.4%; p = 0.05). CONCLUSION Exposure to SHS during childhood and adulthood may be a risk factor for CRS. Furthermore, compared with unexposed CRS cases, SHS exposed cases reported worse nasal symptoms and used more nasal decongestants compared with unexposed cases, suggesting SHS exposure is related to exacerbation and more severe symptoms.

Abstract
A vast number of studies on the unfavorable effects of secondhand smoke (SHS) exist within the international literature, the majority of which evaluate longitudinal epidemiological data. Although limited, the experimental studies that assess the acute and short-term effects of exposure to SHS are also increasing in number. They include cellular, animal, and human studies that indicate a number of pathophysiological mechanisms through which the deleterious effects of SHS may arise. This current review evaluates the existing biological evidence regarding the acute health effects of SHS exposure. Analyses on the inhaled toxicants and the carcinogenicity of SHS are included as well as in-depth discussions on the evidence for acute SHS-induced respiratory, cardiovascular, metabolic, endocrine and immune effects, and SHS-induced influences on oxygen delivery and exercise. The influence of the length of exposure and the duration of the observed effects is also described. Moreover, recent findings regarding the underlying pathophysiological mechanisms related to SHS are depicted so as to generate models that describe the SHS-induced effects on different systems within the human body. Based on the presented biological evidence, it is concluded that brief, acute, transient exposures to SHS may cause significant adverse effects on several systems of the human body and represent a significant and acute health hazard. Future research directions in this area include research on the concentrations of tobacco smoke constituents in the alveolar milieu following SHS exposure, individual susceptibility to SHS, as well as the effects of SHS on neurobehavioral activity, brain cell development, synaptic development, and function.

Abstract
National surveys of the exposure of non-smokers to secondhand smoke based on serum cotinine analyses have consistently identified certain groups within the population including children, males and non-Hispanic Blacks as having relatively greater exposure. Although these differences in mean serum cotinine concentrations probably represent differences in exposure of individuals in their daily lives, it is also possible that metabolic or other differences in response might influence the results. To better define the nature of those findings, we have examined the response of 40 non-smokers including both men and women and African-Americans and whites to sidestream (SS) cigarette smoke generated by a smoking machine under controlled conditions. In this study, participants were exposed to aged, diluted SS smoke (ADSS) generated in an environmental chamber with a mean air nicotine concentration of 140 microg m(-3) and 8.6 ppm CO for 4 h. Salivary cotinine was measured every 30 min, and serum cotinine samples were taken prior to, and 2 h after exposure. Urinary nicotine metabolites and NNAL, a tobacco-specific nitrosamine, and 4-aminobiphenyl (4-AB) haemoglobin adducts were also measured prior to and 2 h following the exposure. Under these uniform, controlled conditions, we found a similar response to ADSS smoke exposure among all the participants. In all cases a significant increase in biomarker concentration was noted following exposure, and the short-term increases in salivary cotinine concentration were quite similar at approximately 12 pg ml(-1) min(-1) among the groups. In this small study, no significant differences by gender or race were seen in the mean increases observed in cotinine, NNAL or 4-AB adducts following 4 h of exposure. Thus, our results are most consistent with a relatively uniform response in tobacco biomarker concentrations following short-term exposure to ADSS tobacco smoke, and suggest that biomarker measurements are capable of effectively indicating increases in exposure among groups of non-smokers.

Abstract
PURPOSE OF REVIEW Recent advances have helped to clarify the role of nerves in allergic rhinitis. RECENT FINDINGS Mast cell histamine release activates histamine H1 receptors on a subset of nonmyelinated Type C afferent trigeminal neurons to convey the sensation of itch. The itch nerves may be distinct from those responsible for burning pain and the dull ache of congestion. Activation of brain stem centers leads to cognition of nasal pruritus, generation of the systemic sneeze reflex and recruitment of local nasal parasympathetic reflexes. These cholinergic reflexes stimulate M3 muscarinic receptors on the submucosal glands to cause exocytosis and the thick mucous discharge of allergic rhinitis. The importance of these neural pathways is demonstrated by the benefits of antihistamines to block itch and sneeze, and anticholinergic drugs to block glandular secretion. One open question remains the role of mediators of allergic inflammation on the sensitivity and reactivity of afferent neurons and these secretory reflexes. SUMMARY The neurology of the nose helps to explain the sensations encountered in allergic rhinitis and opens new frontiers for drug discovery.

Abstract
Previous studies of allergic rhinitis in children have not documented the environmental risk factors for infants at age one. We examined the relationship of environmental tobacco smoke (ETS) and visible mold exposures on the development of allergic rhinitis, rhinitis and upper respiratory infection (URI) in a birth cohort where at least one parent was skin prick test (SPT) positive. ETS exposure and upper respiratory symptoms were obtained by questionnaires. Visible mold was classified as none, low or high during home visit. Infants had a SPT at age one. After adjustment for potential confounders, exposure to >20 cigarettes per day was associated with an increased risk of developing allergic rhinitis at age one [odds ratio (OR)=2.7; 95% CI 1.04-6.8] and rhinitis symptoms during the first year (OR=1.9; 95% CI 1.1-3.2). Infants with low (OR=1.5; 95% CI 1.1-2.3) or high (OR=5.1; 95% CI 2.2-12.1) levels of visible mold in their homes were more likely to have more frequent URI during the first year. Older siblings were protective for development of both rhinitis symptoms and allergic rhinitis. This study suggests that ETS exposure, rather than visible mold, is associated with rhinitis and allergic rhinitis in infants. The analysis also suggests that mold may be a stronger risk factor for URI that ETS.

Abstract
BACKGROUND Inflammatory processes at the mucosal surface may play a role in maintenance of asthma pathophysiology. Cross-sectional studies in asthmatic patients suggest that chemokines such as interleukin 8 (IL-8) are overproduced by respiratory epithelium. OBJECTIVE To test the hypothesis that chemokine levels are persistently elevated in the respiratory secretions of asthmatic children at a stable baseline. METHODS We measured nasal lavage fluid (NLF) levels of chemokines and other mediators at 3- to 4-month intervals in a longitudinal study of asthmatic children, with nonasthmatic siblings as controls. RESULTS In a linear mixed-model analysis, both family and day of visit had significant effects on nasal mediators. Thus, data for 12 asthmatic-nonasthmatic sibling pairs who had 3 or more same-day visits were analyzed separately. For sibling pairs, median eosinophil cationic protein levels derived from serial measurements in NLF were elevated in asthmatic patients compared with nonasthmatic patients, with a near-significant tendency for elevation of total protein and eotaxin levels as well. However, no significant differences were found for IL-8 or several other chemokines. Ratios of IL-13 or IL-5 to interferon-gamma released by house dust mite antigen-stimulated peripheral blood mononuclear cells, tested on a single occasion, were significantly increased for asthmatic patients. CONCLUSIONS Substantial temporal and family-related variability exists in nasal inflammation in asthmatic children. Although higher levels of eosinophil cationic protein are usually present in NLF of patients with stable asthma compared with patients without asthma, chemokines other than eotaxin are not consistently increased. Eosinophil activation at the mucosal surface is a more consistent predictor of asthmatic symptoms than nonspecific elevation of epithelium-derived inflammatory chemokine levels.

Abstract
OBJECTIVE This paper reviews secondhand smoke (SHS) exposure and diseases and symptoms of the upper airway, including the sinuses. Risks to flight attendants, who were occupationally exposed until smoking was banned on all flights, are emphasised. DATA SOURCES A systematic database search was conducted; the US Surgeon General's reports and other major reviews were evaluated. Literature summarised by National Research Council (NRC) reports on the airline cabin environment are included. STUDY SELECTION A limited number of research publications on adults were identified; these are included. Many studies cited by the NRC were never published and information is taken directly from the reports. DATA EXTRACTION Data from observational studies of cabin crews and the general public were extracted from surveys; exposure monitoring of cabin crews is reported. Data from controlled exposure studies are included; most are challenge studies using volunteers screened for sensitivity to SHS. DATA SYNTHESIS Evidence shows that active and passive smoking cause upper airway diseases, including sinonasal and laryngeal cancers in adult active smokers. Experimental studies indicate that brief exposures to SHS result in nasal mucosa inflammation. However, direct evidence on sinusitis is limited. CONCLUSIONS Evidence does not show a strong connection between active smoking and sinusitis, and active smokers have substantial exposures to SHS. However, extrapolation of these studies to cabin crews needs to be cautious, as other environmental conditions may increase risk for upper airway disease and symptoms. Surveys of cabin crews, while flawed, consistently indicate high rates of upper airway symptoms.

Abstract
We investigated the mechanisms of wood smoke-induced increases in nasal airway resistance (RNA) and airway reactivity in anesthetized rats. Delivery of wood smoke into a functionally isolated nasal airway produced an increase in RNA, which was attenuated by CP-96,345 [a tachykinin NK(1) receptor antagonist; (2S,3S)-cis-2-(diphenylmethyl)-N-((2-methoxyphenyl)-methyl)-1-azabicyclo(2.2.2.)-octan-3-amine] or atropine. Additionally, smoke pre-exposure animals displayed a greater amplitude and a longer duration of RNA responses to capsaicin or histamine provocation, as compared to air controls. This enhanced airway reactivity to capsaicin or histamine was largely alleviated by CP-96,345 or atropine. The nasal secretory responses to capsaicin or histamine in smoke pre-exposure animals were similar to those in air controls. We concluded that (1) reflex cholinergic and tachykininergic mechanisms play important roles in wood smoke-induced increases in nasal airway resistance and airway reactivity, and (2) this nasal airway hyperreactivity might not be due to an exaggerated secretory response, but is presumably due to augmented nasal swelling.

Abstract
Tobacco smoking and exposure to environmental tobacco smoke (ETS) have both been implicated in a number of acute and chronic medical problems including heart and lung disease and several cancers. The impact of tobacco smoke on disorders of the nose and paranasal sinuses is less well understood, although there is growing evidence that such exposure can have a significant impact on nasal and sinus function. A comprehensive review of the literature reveals that tobacco smoking is associated with acute and chronic rhinitis, but may actually be negatively correlated with the development of allergic rhinitis. In those patients with allergies, nasal and sinus symptoms may be exacerbated by tobacco smoking. ETS exposure is associated with acute and chronic nasal symptoms in adults and children, snoring in children and teenagers, and may be associated with an earlier onset and more significant symptoms for individuals with a predisposition to developing allergies. Both primary and environmental tobacco smoke are related to increases in nasal and sinus cancer. Tobacco smoking and ETS are associated with significant nasal and sinus disease and cancer.
