Abstract
Background While chronic rhinosinusitis is a common complication of allergic rhinitis, the link between acute rhinosinusitis and allergic rhinitis is unclear. The aim of this study was to evaluate the risk of incident acute rhinosinusitis among pediatric patients with allergic rhinitis, using a nationwide, population-based health claims research database. Methods Newly diagnosed allergic rhinitis patients aged 5–18 years were identified from the health claim records of the Longitudinal Health Insurance Database 2000 of Taiwan’s National Health Insurance Research Database. A comparison cohort was assembled by randomly selecting patients from the same database with frequency matching by sex, age group, and index year. All patients were followed until a diagnosis of acute rhinosinusitis or the end of the follow-up period. Cox proportional hazards model was used to assess the association between allergic rhinitis and acute rhinosinusitis. Results Of the 43,588 pediatric patients included in this study, 55.4% were male and 43.9% were between the ages of 5.0–7.9 years. The risk of acute rhinosinusitis was significantly higher in pediatric patients with allergic rhinitis compared to those without the condition (adjusted hazard ratio = 3.03, 95% confidence interval = 2.89–3.18). Similar hazard ratios were observed between male and female pediatric patients. Conclusions This secondary cohort study using a nationwide, population-based health claim data of the Taiwan’s NHIRD showed that allergic rhinitis was significantly associated with a higher risk of acute rhinosinusitis among pediatric patients.

The association of ambient PM 2.5 with school absence and symptoms in schoolchildren: a panel study. Pediatr Res 2018; 84:28-33. [PMID: 29795198 PMCID: PMC6581566 DOI: 10.1038/s41390-018-0004-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 03/01/2018] [Accepted: 03/10/2018] [Indexed: 01/02/2023]
Abstract
BACKGROUND Children are a susceptible population to exposure of ambient fine particulate air pollution (PM2.5), and the associated symptoms are sensitive prevalent indicators of morbidity. However, few studies to date investigate the association between PM2.5 exposure and school absence and symptoms. METHODS In a panel study including 20,291 observations in 615 schoolchildren 8-13 years of age, we asked the participants to record their school absence and symptoms on every school day from 17 November to 31 December 2014 in Jinan, China. We used the generalized linear mixed effects models to examine the adverse effects of ambient PM2.5 on school absence and symptoms, adjusting for covariates including meteorological and individual factors. RESULTS The 3-day moving average of PM2.5 was significantly associated with school absence (1.37; 95% CI: 1.07-1.74) and increases in symptoms of the throat (1.03; 95% CI: 1.00-1.05), nose (1.03; 95% CI: 1.01-1.06), and skin (1.09; 95% CI: 1.06-1.12). High PM2.5 exposure also increased the risks of individual symptoms, especially for cough (1.02; 95% CI: 1.00-1.04), sneezing (1.03; 95% CI: 1.00-1.07), and stuffy nose (1.09; 95% CI: 1.02-1.17). CONCLUSION High PM2.5 exposure is a risk factor for the health of schoolchildren. Allocation of medical resources for children should take into account the ambient PM2.5 concentrations and be proportioned accordingly.

Abstract
The aim of the present study was to investigate the effect of glucocorticoid intervention on olfactory dysfunction in mice with allergic rhinitis (AR). An AR animal model was established by intraperitoneal injection and intranasal application of ovalbumin to mice. The olfactory function of the mice was evaluated using a buried food test, and morphological changes in the nasal mucosa were determined using hematoxylin and eosin staining. The expression of olfactory marker protein (OMP) in the olfactory mucosa was tested by immunohistochemistry, and was observed on days 7 and 14 after the application of glucocorticoid. The incidence rate of olfactory dysfunction in AR mice was 75.34%, and the olfactory epithelium became thinner in mice with AR compared to the control group. In addition, the expression of OMP in the olfactory epithelium was downregulated in mice with AR compared with the control group. Expression of OMP in the olfactory epithelium was upregulated in the budesonide group A and betamethasone group A compared with the medicine-free group, whereas the expression of OMP in the olfactory epithelium of budesonide group A or betamethasone group A was not significantly different from the control group. Moreover, the expression of OMP in the budesonide group B was similar to budesonide group A, and expression of OMP in betamethasone group B was similar to betamethasone group A. The expression of OMP in olfactory mucosa is downregulated in AR mice with olfactory dysfunction. Following the application of glucocorticoid, the expression of OMP in the olfactory mucosa in mice is upregulated. Moreover, intranasal local glucocorticoid has a low incidence of systemic adverse reactions, and is recommended for the treatment of olfactory dysfunction in AR.

Abstract
A high proportion of suicides visit their medical provider in the month prior to death, but depression, suicidal thoughts, and substance use are seldom addressed. For the clinicians routinely treating a substantial patient population with allergic diseases, there are additional concerns, as allergy has been linked with both depression and suicidal behavior. While psychotropic medications may affect diagnosis of allergies, medications used to treat allergies impact mood and behavior. Thus, we present an overview of the overlap of allergic rhinitis with depression and suicidal behavior in adults, based on clinical and epidemiological data, and our research and clinical experience. In summary, we suggest: 1) inquiring among patients with allergies about personal and family history of depression, substance use disorders, suicidal ideation and attempts 2) increased mindfulness regarding the potential effects of allergy medications on mood and behavior; and 3) for people identified with certain types of depression or increased suicide risk, a systematic multilevel collaborative approach. While for practical reasons the majority of patients with depression will continue to be treated by general or family practitioners, the allergy-treating provider should always consider integrated care for bipolar, psychotic or suicidal depression and incomplete remission, or relapsing and highly recurrent course. While awaiting results of much needed basic and clinical research to guide clinical approach for patients with comorbid allergic rhinitis and depression, the simple steps recommended here are expected to improved clinical outcomes in depression, including, on a large scale, reduced premature deaths by suicide.

Abstract
BACKGROUND Microbes and allergens can stimulate the nasal mucosa, potentially leading to the development of acute bacterial rhinosinusitis (ABRS). This study was designed to determine if allergen exposure alters the sinonasal microbiome. METHODS We performed a parallel observational study of healthy adults with seasonal allergic rhinitis (SAR; grass or tree, n = 20) or nonallergic subjects (n = 19). Microbiota specimens were obtained by endoscopy from the middle meatus and vestibule before and during the relevant season and were analyzed by terminal restriction fragment length polymorphism analysis. Differences in bacterial microbiota were assessed by standard ecological measures of bacterial diversity. Quality of life and symptom scores were recorded, and nasal lavages for eosinophils were performed. RESULTS SAR subjects had increased nasal symptoms in season, impaired disease-specific quality of life, and increased nasal eosinophils, compared with no changes in nonallergic subjects. During the season, SAR subjects had a significantly greater variety of organisms in the middle meatus compared with nonallergic subjects (p < 0.036) and increased bacterial diversity (Shannon index, p < 0.013). We found a significant positive correlation between bacterial diversity in the middle meatus during the season and the nasal lavage eosinophil count of SAR subjects. There were no significant changes in the nasal vestibule (p > 0.05, all comparisons). CONCLUSION The interaction of allergy and microbiota may affect the sinonasal physiology, with broad implications for several airway diseases. Characterization of the specific organisms involved using next-generation sequencing may clarify the relationship between allergic inflammation and ABRS. This finding may help explain why allergic inflammation predisposes to ABRS.

Abstract
The relevance of using mouse models to represent human allergic pathologies is still unclear. Recent studies suggest the limitations of using models as a standard for assessing immune response and tolerance mechanisms, as mouse models often do not sufficiently depict human atopic conditions. Allergy is a combination of aberrant responses to innocuous environmental agents and the subsequent TH2-mediated inflammatory responses. In this review, we will discuss current paradigms of allergy - specifically, TH2-mediated and IgE-associated immune responses - and current mouse models used to recreate these TH2-mediated pathologies. Our overall goal is to highlight discrepancies that exist between mice and men by examining the advantages and disadvantages of allergic mouse models with respect to the human allergic condition.

Abstract
BACKGROUND Acute sinusitis is the inflammation and swelling of the nasal and paranasal mucous membranes and is a common reason for patients to seek primary care consultations. The related impairment of daily functioning and quality of life is attributable to symptoms such as facial pain and nasal congestion. OBJECTIVES To assess the effects of systemic corticosteroids on clinical response rates and to determine adverse effects and relapse rates of systemic corticosteroids compared to placebo or standard clinical care in children and adults with acute sinusitis. SEARCH METHODS We searched CENTRAL (2014, Issue 1), MEDLINE (1966 to February week 1, 2014) and EMBASE (January 2009 to February 2014). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing systemic corticosteroids to placebo or standard clinical care for patients with acute sinusitis. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the methodological quality of the trials and extracted data. MAIN RESULTS Five RCTs with a total of 1193 adult participants met our inclusion criteria. We judged methodological quality to be moderate in four trials and high in one trial. Acute sinusitis was defined clinically in all trials. However, the three trials performed in ear, nose and throat (ENT) outpatient clinics also used radiological assessment as part of their inclusion criteria. All participants were assigned to either oral corticosteroids (prednisone 24 mg to 80 mg daily or betamethasone 1 mg daily) or the control treatment (placebo in four trials and non-steroidal anti-inflammatory drugs (NSAIDs) in one trial). In four trials antibiotics were prescribed in addition to oral corticosteroids or control treatment, while one trial investigated the effects of oral corticosteroids as a monotherapy.When combining data from the five trials, participants treated with oral corticosteroids were more likely to have short-term resolution or improvement of symptoms than those receiving the control treatment: at days three to seven (risk ratio (RR) 1.3, 95% confidence interval (CI) 1.1 to 1.6; risk difference (RD) 17%, 95% CI 6% to 29%) and at days four to 14 (RR 1.2, 95% CI 1.0 to 1.5; RD 14%, 95% CI 1% to 27%). A sensitivity analysis including the four trials with placebo as a control treatment showed similar results but with a lesser effect size: at days three to seven (RR 1.2, 95% CI 1.1 to 1.3; RD 11%, 95% CI 4% to 17%) and days four to 14 (RR 1.1, 95% CI 1.0 to 1.2; RD 8%, 95% CI 2% to 13%). Statistical heterogeneity was high for many analyses. Subgroup analyses revealed that corticosteroid monotherapy had no beneficial effects. Furthermore, scenario analysis showed that outcomes missing from the trial reports might have introduced attrition bias (a worst-case scenario showed no statistically significant beneficial effect of oral corticosteroids). No trial reported effects on relapse or recurrence rates. Reported side effects in patients treated with oral corticosteroids were mild (nausea, vomiting, gastric complaints) and did not significantly differ from those receiving placebo. AUTHORS' CONCLUSIONS Oral corticosteroids as a monotherapy appear to be ineffective for adult patients with clinically diagnosed acute sinusitis. Current data on the use of oral corticosteroids as an adjunctive therapy to oral antibiotics are limited: almost all trials are performed in secondary care settings and there is a significant risk of bias. This limited evidence suggests that oral corticosteroids in combination with antibiotics may be modestly beneficial for short-term relief of symptoms in acute sinusitis, with a number needed to treat to benefit of seven for resolution or symptom improvement. A large primary care factorial trial is needed to establish whether oral corticosteroids offer additional benefits over antibiotics in acute sinusitis.

Abstract
A 50-year-old woman with nonallergic rhinitis, asthma, and aspirin intolerance presented with worsening symptoms of nasal congestion, purulent drainage, and anosmia. Nasal polyps were visualized on anterior rhinoscopy, and there was evidence of chronic rhinosinusitis (CRS) on imaging studies during work-up for another medical condition. Over a 2-year period she had numerous bouts of acute exacerbations of CRS which required multiple courses of antibiotics; however, she was unwilling to undergo surgery to reduce polyp burden. She successfully underwent aspirin desensitization and experienced partial relief of symptoms with daily aspirin ingestion. Nasal obstruction is a common symptom that can result from multiple causes, including mucosal disorders (eg, allergic and nonallergic rhinitis, rhinosinusitis, sarcoid) and structural disorders (eg, nasal septal deviation, tumors, mucoceles). The various causes and work-up for nasal obstruction are discussed with emphasis placed on CRS, which is a prevalent disease characterized by inflammation of the nose and paranasal sinuses for a duration of >12 weeks. The different subtypes of CRS, including CRS with and without nasal polyps, allergic fungal rhinosinusitis, and aspirin-exacerbated respiratory disease, are discussed along with pathogenesis, diagnosis, and treatment options.

Abstract
BACKGROUND Patients with acute rhinosinusitis are frequently encountered in primary care. Although corticosteroids are being increasingly used for symptom control, evidence supporting their use is inconclusive. We conducted a randomized controlled trial to examine the effectiveness of systemic corticosteroid monotherapy for clinically diagnosed, uncomplicated acute rhinosinusitis. METHODS We conducted a block-randomized, double-blind, placebo-controlled clinical trial at 54 primary care practices (68 family physicians) in the Netherlands between Dec. 30, 2008, and Apr. 28, 2011. Adult patients with clinically diagnosed acute rhinosinusitis were randomly assigned to receive either prednisolone 30 mg/d or placebo for 7 days and asked to complete a symptom diary for 14 days. The primary outcome measure was the proportion of patients with resolution of facial pain or pressure on day 7. RESULTS Of the 185 patients included in the trial (93 in the treatment group, 92 in the placebo group), 2 withdrew from the study and 9 were excluded from the primary analysis because of incomplete symptom reporting. The remaining 174 patients (88 in the treatment group, 86 in the placebo group) were included in the intention-to-treat analysis. The proportions of patients with resolution of facial pain or pressure on day 7 were 62.5% (55/88) in the prednisolone group and 55.8% (48/86) in the placebo group (absolute risk difference 6.7%, 95% confidence interval -7.9% to 21.2%). The groups were similar with regard to the decrease over time in the proportion of patients with total symptoms (combined symptoms of runny nose, postnasal discharge, nasal congestion, cough and facial pain) and health-related quality of life. Adverse events were mild and did not differ significantly between the groups. INTERPRETATION Systemic corticosteroid monotherapy had no clinically relevant beneficial effects among patients with clinically diagnosed acute rhinosinusitis.

Abstract
BACKGROUND Rhinitis and sinusitis are very common medical conditions and have been shown to be frequently associated. The role of allergies in the pathogenesis of chronic rhinosinusitis has been confirmed; however, the role of allergies in acute rhinosinusitis is debatable. Nonetheless, allergies are an important factor in the development of rhinosinusitis. OBJECTIVE To evaluate the incidence of allergic rhinitis in patients with acute rhinosinusitis and identify the clinical spectrum in Taiwan. METHODS This study randomly recruited 69 participants between 3 and 12 years of age with acute rhinosinusitis over the period of one and a half years. All participants underwent a nasal peak expiratory flow rate (nPEFR) test, skin-Prick test (SPT), nasal smear examination, nasal culture, radiography (Water's projection) and were requested to complete the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) as well as provide their allergic history. RESULTS Among the 69 participants in the study, 27 (39.1%) participants were shown to have allergic rhinitis. The most troublesome symptoms among the 69 participants with acute rhinosinusitis were postnasal drip (3.00 ± 1.29), nasal obstruction (2.94 ± 1.39) and cough (2.67 ± 1.42). The most troublesome symptoms among the 27 participants with acute rhinosinusitis combined with allergic rhinitis were nasal obstruction (3.33 ± 1.24), postnasal drip (3.22 ± 1.09) and itchy eyes (2.74 ± 1.43) and with the higher values. In addition, the participants (≧ 6 y/o) with acute rhinosinusitis combined with allergic rhinitis had significantly lower nPEFR values compared with the nonatopic children (75.2 ± 18.2 vs 96.6 ± 21.4, p<0.05). If nPEFR is below 75 mL/min, the positive predict value in the patients of acute rhinosinusitis is 75.0% combined with allergic rhinitis (sensitivity 63.2%; specificity 85.7%). Streptococcus pneumoniae (29.0%), Haemophilus influenzae (20.3%), and Moraxella catarrhalis (17.4%) were the major isolated pathogens in this study. The prevalence of colonization with Staphylococcus aureus in the 69 participants with acute rhinosinusitis was 23.2%, and 15.9% for methicillin-resistant S. aureus (MRSA). CONCLUSION This study demonstrated that the bacteriological properties of acute rhinosinusitis among children in Taiwan are the same as those in other parts of the world; however, the prevalence of colonization by MRSA was higher than among healthy children. Second, atopic children were more likely to develop acute rhinosinusitis than nonatopic children. Third, most Taiwanese children with acute rhinosinusitis complained of postnasal drip, nasal obstruction and cough. If a child suffering from acute rhinosinusitis complained of severe nasal obstruction (nPEFR≦75 mL/min), the doctor should be alerted to atopic conditions requiring further treatment. The issues dealt with in this study may require further research with a larger sample population over an extended period of time to verify these conclusions.

Abstract
BACKGROUND Acute sinusitis is a common reason for patients to seek primary care consultations. The related impairment of daily functioning and quality of life is attributable to symptoms such as facial pain and nasal congestion. OBJECTIVES To assess the effectiveness of systemic corticosteroids in relieving symptoms of acute sinusitis. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 2, 2011, which includes the Acute Respiratory Infections (ARI) Group's Specialised Register, the Database of Reviews of Effects (DARE) and the NHS Health Economics Database, MEDLINE (1966 to June week 2, 2011) and EMBASE (January 2009 to June 2011). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing systemic corticosteroids to placebo or standard clinical care for patients with acute sinusitis. DATA COLLECTION AND ANALYSIS Two review authors independently assessed methodological quality of the trials and extracted data. MAIN RESULTS Four RCTs with a total of 1008 adult participants met our inclusion criteria. We judged studies to be of moderate methodological quality. Acute sinusitis was defined clinically in all trials. However, the three trials performed in ear, nose and throat (ENT) outpatient clinics also used radiological assessment as part of their inclusion criteria. All participants received oral antibiotics and were assigned to either oral corticosteroids (prednisone 24 mg to 80 mg daily or betamethasone 1 mg daily) or the control treatment (placebo in three trials and non-steroidal anti-inflammatory drugs (NSAIDs) in one trial). In all trials, participants treated with oral corticosteroids were more likely to have short-term resolution or improvement of symptoms than those receiving the control treatment: at Days 3 to 7, risk ratio (RR) 1.4, 95% CI 1.1 to 1.8; risk difference (RD) 20% (6% to 34%) and at Days 4 to 10 or 12, RR 1.3, 95% CI (1.0 to 1.7), RD 18% (3% to 33%). An analysis of the three trials with placebo as a control treatment showed similar results but with a lesser effect size: Days 3 to 6: RR 1.2, 95% CI (1.1 to 1.4), RD 12% (5% to 19%) and Days 4 to 10 or 12: RR 1.1, 95% CI (1.0 to 1.2), RD 10% (3% to 16%). Scenario analysis showed that outcomes missing from the trial reports might have introduced attrition bias (a worst-case scenario showed no statistically significant beneficial effect of oral corticosteroids). We did not identify any data on the long-term effects of oral corticosteroids on this condition, such as effects on relapse or recurrence rates. Reported side effects of oral corticosteroids were limited and mild. AUTHORS' CONCLUSIONS Current evidence suggests that oral corticosteroids as an adjunctive therapy to oral antibiotics are effective for short-term relief of symptoms in acute sinusitis. However, data are limited and there is a significant risk of bias. High quality trials assessing the efficacy of systemic corticosteroids both as an adjuvant and a monotherapy in primary care patients with acute sinusitis should be initiated.

Otolaryngol Head Neck Surg 2010; 142:659-64.

Abstract
OBJECTIVE Pilot study examining toll-like receptor 9 (TLR9) expression by sinonasal epithelial cells in allergic rhinitis (AR) subjects with and without a history of recurrent acute rhinosinusitis (RARS). STUDY DESIGN Cohort study. SETTING Outpatient clinic. SUBJECTS AND METHODS Adult subjects were eligible for study if skin tested positive for inhalant allergens, and positive allergens were in season at time of study. Subjects were considered to have AR+RARS if they had four symptomatic episodes with major/minor factors in 12 months and CT evidence of sinusitis. Eight AR-only subjects and 13 AR+RARS subjects underwent endoscopic-guided cell brushing from the middle meatus. Flow cytometry for TLR9 expression was performed on collected fresh sinonasal epithelial cells. RESULTS The AR+RARS group was found to have a significant increase in TLR9 expression in the sinonasal epithelium (66% +/- 30%) compared with that of AR-only patients (32% +/- 21%; P = 0.011). CONCLUSION The significant difference in expression of TLR9 in allergic sinusitis patients compared with allergy-only patients in this study may indicate a difference in the role of innate immunity in these groups. The results suggest that expression of innate immune markers such as TLR9 may be upregulated in response to repeated microbial insults in AR+RARS. Further research is necessary to determine whether an initial impairment of innate immune gene expression may predispose some AR patients to subsequent development of RARS.

Abstract
Allergic rhinitis (AR) is a common health problem that affects adults, adolescents and children and is often undiagnosed or inadequately treated. Because AR is not a life-threatening disease, many patients do not seek medical treatment for their symptoms, and others self-medicate with over-the-counter medications, often sedating antihistamines. However, untreated or inadequately treated AR can substantially impair overall quality of life (QOL) by causing fatigue, headache, cognitive impairment and other problems. The risk for comorbid conditions, such as asthma, otitis media, and lymphoid hypertrophy with obstructive sleep apnea, can increase, and the symptoms of AR can worsen if AR is not adequately treated. Among the symptoms of AR, nasal congestion has been described by patients as the most bothersome because it disrupts sleep, resulting in diminished daytime performance. A new congestion screening tool, the Congestion Quantifier, has been developed to aid in the diagnosis and treatment of AR and to help guide treatment decisions. Intranasal corticosteroids (INSs) are recommended as effective pharmaceutical treatments for controlling the symptoms of AR. Randomized, controlled trials in children and adults have demonstrated that INSs relieve rhinitis symptoms, thereby improving QOL in individuals with seasonal or perennial AR. Most INSs are approved for use in children >or=6 years of age, but mometasone furoate and fluticasone furoate are approved for use in children as young as 2 years of age and fluticasone propionate for children >or=4 years old. Long-term benefits have also been seen with the use of immunotherapy, although some patients, especially children, resist the injections used in subcutaneous immunotherapy. Recent studies with sublingual immunotherapy have indicated that it might be an effective and well-tolerated alternative to immunotherapy injections.

Abstract
OBJECTIVE To determine the effects of eosinophilic inflammation on olfactory sensory neuron cell death. STUDY DESIGN Mice were sensitized to intranasal Aspergillus fumigatus extract and subsequently challenged acutely or chronically with the same allergen. The olfactory neuroepithelium was assessed for immunohistochemical evidence of apoptosis and inflammation. RESULTS Sensitized mice challenged with allergen demonstrated elevated eosinophil infiltration of the respiratory and olfactory mucosae, with olfactory sensory neuron apoptosis. Remarkably, massive neuronal apoptosis without eosinophil infiltration occurred in nonsensitized mice after a single dose of extract. CONCLUSION Intranasal sensitization with A fumigatus results in a model with multifactorial effects. Protocols using A fumigatus to induce allergic rhinitis may need modification to allow confident interpretation. SIGNIFICANCE Fungal allergens may contribute to anosmia through the induction of olfactory sensory neuron apoptosis, with and without prior sensitization.

Abstract
Systemic acute rhinosinusitis therapy consists mostly of antibiotic treatment because pathogens play a major role. Amoxicillin is the drug of choice for treatment of acute rhinosinusitis, with second- and third- generation cephalosporins, azythromycin, clarithromycin, and telithromycin as possible options, especially in the case of allergy to amoxicillin. If the clinical course suggests that an anaerobic pathogen is more likely, clindamycin or metronidazole can be considered in combination with a broad-spectrum drug. In antimicrobial treatment of chronic sinusitis there is no consensus on treatment length, organism coverage, or which antibiotics are most effective because the bacteriology is variable with polymicrobial anaerobic and aerobic organisms present. Adjuvant therapies need to be proven by additional studies. Chronic rhinosinusitis is heterogeneous and treatment should vary according to the causative factor involved. Short courses of systemic steroids have been found very useful to decrease mucosal swelling and inflammation in chronic rhinosinusitis. However, no randomized controlled studies have been performed to validate their efficacy in children. A variety of other agents are used in the treatment of chronic rhinosinusitis including antihistamines, decongestants, and leukotriene modifiers. To date, there is no good evidence from randomized controlled studies to support the use of any of these agents in the treatment of this disease in either children or adults.

Abstract
Chronic rhinosinusitis (CRS) is presently classified into two subgroups: CRS without and CRS with nasal polyps. A variety of inflammatory mediators, including cytokines and chemokines, as well as adhesion molecules and matrix metalloproteinases, are upregulated in both subgroups of CRS; remodeling is also observed in both. However, there are also characteristic differences. Whereas CRS without nasal polyps has more neutrophilic infiltration, in CRS with nasal polyps (especially when associated with allergy/asthma) eosinophil infiltration is strikingly increased. Although several features of remodeling (eg, squamous metaplasia, basement membrane thickening, collagen deposition, hyperplasia of mucous glands, and goblet cells) are features seen in both subgroups of CRS, epithelial shedding as observed in asthma is not seen in either subgroup. Furthermore, pseudocyst formation seen in CRS with nasal polyps is not seen in CRS without nasal polyps.

Abstract
The association between chronic rhinosinusitis (CRS) and allergy of the upper respiratory system has been discussed for many years,but much of this discussion has been anecdotal. Although epidemiologic evidence supports the increased prevalence of CRS among patients who have allergic rhinitis, and treatment of upper airway inflammation and allergy has been shown to decrease morbidity in patients who have CRS, but pathophysiologic mechanisms linking the two disease states have not been well elucidated. This article examines data supporting the link between upper airway allergic disease and CRS. It proposes a frame work for the treatment of CRS, with consideration of managing the allergic inflammation commonly noted in this disease. Finally, it discusses avenues for potential future research in evaluating the comorbidities of allergic inflammation and CRS.

Abstract
Immunotherapy with allergens is an established therapy for allergic rhinitis. It reverses the T(H2)-skewed immune response and induces immune tolerance to the allergen applied. Weekly and later monthly allergen injections with sustained-release preparations over 3 years are the current reference method. Also chemically modified allergens and immune adjuvants may be used. Immunotherapy reduces allergy symptoms, the consumption of antiallergic drugs, and the mucosal inflammatory reaction. A particular characteristic is the reduction of asthma morbidity and additional sensitizations to new allergens. In Germany, serious side effects arise on the average per every 10,000 injections, and an anaphylactic shock approximately per every 250,000 injections. Serious adverse events are substantially rarer with sublingual immunotherapy, but they also occur. At present, efficacy of sublingual immunotherapy has been demonstrated in adults with pollen allergy. The effects of immunotherapy last for several years after its termination. As a consequence, immunotherapy is also economically reasonable.
