Abstract
The allergen challenge test has been the mainstay of diagnosis of allergic diseases for a long time since it offers a direct proof of the clinical relevance of a particular allergen for the allergic disease symptoms and severity. Standardisation and availability for daily practice (including safety issues) are still to be refined but most of the challenge tests have safely crossed the border from research tools to diagnostic tests available for daily practice for a well trained clinical staff.

Tanno LK, Calderon MA, Goldberg BJ, Akdis CA, Papadopoulos NG, Demoly P. Categorization of allergic disorders in the new World Health Organization International Classification of Diseases. Clin Transl Allergy 2014; 4:42.

Abstract
BACKGROUND Although efforts to improve the classification of hypersensitivity/allergic diseases have been made, they have not been considered a top-level category in the International Classification of Diseases (ICD)-10 and still are not in the ICD-11 beta phase linearization. ICD-10 is the most used classification system by the allergy community worldwide but it is not considered as appropriate for clinical practice. The Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) on the other hand contains a tightly integrated classification of hypersensitivity/allergic disorders based on the EAACI/WAO nomenclature and the World Health Organization (WHO) may plan to align ICD-11 with SNOMED CT so that they share a common ontological basis. METHODS With the aim of actively supporting the ongoing ICD-11 revision and the optimal practice of Allergology, we performed a careful comparison of ICD-10 and 11 beta phase linearization codes to identify gaps, areas of regression in allergy coding and possibly reach solutions, in collaboration with committees in charge of the ICD-11 revision. RESULTS We have found a significant degree of misclassification of terms in the allergy-related hierarchies. This stems not only from unclear definitions of these conditions but also the use of common names that falsely imply allergy. The lack of understanding of the immune mechanisms underlying some of the conditions contributes to the difficulty in classification. CONCLUSIONS More than providing data to support specific changes into the ongoing linearization, these results highlight the need for either a new chapter entitled Hypersensitivity/Allergic Disorders as in SNOMED CT or a high level structure in the Immunology chapter in order to make classification more appropriate and usable.

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
PURPOSE OF REVIEW The aim of this review is to provide an overview of the causes of olfactory dysfunction, their evaluation and management, with a main focus on the gradual/progressive loss of smell. RECENT FINDINGS As the sense of smell gives us essential information about our environment, its loss can cause nutritional and social problems while threatening an individual's safety. Recent surveys have shown quite a substantial prevalence of hyposmia (one out of four people) and anosmia (one out of 200 people) in a variety of populations. SUMMARY Nasal inflammatory diseases such as allergic rhinitis and predominantly chronic rhinosinusitis account for the major and common causes of gradual/progressive loss of smell. However, they are also among the most successfully treated forms of olfactory dysfunction. The management of gradual/progressive smell deficit must always address its etiological causes. In most cases, a detailed medical history and nasal examination, smell testing, and imaging will help to establish an appropriate diagnosis. In addition to anti-inflammatory therapy, mainly nasal and systemic corticosteroids, recent investigations on smell training suggest that the controlled exposure to selected odors may increase olfactory performance.

Abstract
Sublingual immunotherapy is currently considered a viable alternative to the subcutaneous route. The body of evidence of its efficacy is based on the results of 77 clinical trials and 7 meta-analyses, that have been published so far. Nonetheless, the experimental evidence is partially weak due to the large heterogeneity of studies, namely: doses, regimens, patient selection, duration of treatment, outcomes and reporting. In addition, it is virtually impossible to compare the potency of extracts produced by different manufacturers. Also, there is large variability in reporting and in the classification of adverse events, either systemic or local, so that only a rough estimate can be provided. Considering all these aspects, efforts are needed to harmonize the methodology, outcome measures and reporting of SLIT clinical trials, to achieve the ability of comparing the results of various studies. International societies and the World Allergy Organization have recently provided general recommendations on how to design and conduct trials which can provide more interpretable and homogeneous data.

Abstract
There are limited numbers of articles, studying combined use of antihistamines. In this study, we compare single therapy of Apo-Cetirizine with a new regimen of intermittent sequential therapy with cetirizine, loratadine and chlorpheniramine in treatment of seasonal allergic rhinitis. This randomized clinical trial was performed between April and September at the peak prevalence of seasonal allergic rhinitis. Fifty-four eligible patients diagnosed clinically to have seasonal allergic rhinitis were randomized in two groups: 24 cases in single therapy arm, received Apo-Cetirizine 10 mg tablet daily and in other arm, 30 patients received sequential regimen of cetirizine 10 mg tablet, loratadine 10 mg tablet and chlorpheniramine 4 mg tablet, one tablet each day. Major Symptom Complex Score (MSCS) and Total Symptom Complex Score (TSCS) of patients were recorded before treatment and after 30 days of treatment in two groups. The average post-treatment MSCS and TSCS in combination therapy group showed better improvement than single therapy group but difference was not statistically significant (p value = 0.053 and p value = 0.104 respectively). Combination therapy regimen was better in improvement of nasal congestion (p value = 0.006). There were no significant difference between two groups in efficacy, side effects and patient's satisfaction. Combination therapy would be effective on a wide spectrum of symptoms with lower price and theoretically offers lower chance of tolerance and re-appearance of complaints.

Abstract
Background SUBLIVAC FIX Birch (SUB-B) is a liquid oral preparation of Betula verrucosa pollen extract for the treatment of allergic rhinitis/rhinoconjuctivitis induced by birch pollen. The major allergen content of SUB-B and Staloral Birch (Stal-B) have been shown to be comparable. In order to compare the clinical efficacy and safety of both products, the present study was designed to investigate efficacy of treatment with SUB-B compared to Stal-B by means of reduction in allergy symptoms assessed by a titrated nasal provocation test (TNPT) in subjects suffering from IgE mediated allergy complaints triggered by birch pollen. Methods A prospective, randomized, open, blinded endpoint (PROBE), controlled, single-centre study in 74 birch allergic adults was performed. Treatment consisted of either SUB-B (10,000 AUN/ml) or Stal-B (initial phase 10 I.R./ml and maintenance phase 300 I.R./ml) for 16–20 weeks at maintenance dose. The primary efficacy outcome was defined by the difference in change of the TNPT-threshold dose between the two treatment groups at baseline and after completion of treatment. Secondary outcomes included determination of birch pollen specific IgE and IgG levels, safety lab and ECG. During the first 30 days of treatment, subjects were requested to fill out a diary concerning compliance with study medication, occurrence of AEs and the use of concomitant medication. Results Analysis of the primary efficacy parameter showed that the percentage of subjects showing a beneficial treatment effect was similar in both treatment groups, 33.3% for SUB-B vs. 31.4% for Stal-B in the intention to treat population. Evaluation of the immunologic response, showed that treatment with SUB-B and Stal-B induced similar increases (approximately 2 times) in IgE, IgG and IgG4 specific for Bet v 1. In total, 143 related adverse events (AEs) were reported. The majority of the AEs was of mild intensity. The same pattern of AEs was observed for both products. No clinically relevant changes in other safety parameters, such as safety laboratory parameters, vital signs, physical examination and ECGs were observed. Conclusion Taken together, treatment with both products was effective by means of reduction in allergic symptoms during a TNPT. In addition, safety analysis revealed a good tolerability of both SLIT extracts.

Abstract
Inferior turbinate hypertrophy is a frequent cause of nasal airway obstruction and drastically impairs patients' quality of life. Surgical reduction of the inferior turbinates can be used for patients who did not respond to medical therapy. A number of studies have been performed to identify the most effective technique. The aim of this study was to compare the effectiveness of submucosal resection (SMR) and radiofrequency turbinate volume reduction (RFTVR) in patients with inferior turbinate hypertrophy. A prospective, randomized case-control study was conducted. Sixty patients with inferior turbinate hypertrophy refractory to medical therapy were prospectively and randomly assigned to two groups: SMR and RFTVR. A visual analog scale (VAS) and the nasal inspiratory peak flow (NPIF) were analyzed pre- and postoperatively at the first week and second month. Magnetic resonance imaging was performed pre- and postoperatively at the second month. The surgical outcomes were compared statistically using subjective and objective measures. Significant turbinate volume reduction was achieved in both the SMR and RFTVR groups. However, turbinate volume reduction was significantly greater in the SMR than in the RFTVR group at the second month postoperatively. NIPF and VAS scores were improved after both procedures at the second month postoperatively. Beside this, surgical outcomes were significantly better after SMR in terms of NIPF and VAS scores. In this study, we demonstrated that both SMR and RFTVR are effective for inferior turbinate hypertrophy. Turbinate volume reduction, improvement of subjective nasal obstruction symptoms, and NIPF after SMR were significantly superior to those after RFTVR.

Abstract
BACKGROUND Nasal hyper-reactivity is an increased sensitivity of the nasal mucosa to various nonspecific stimuli. Both allergic rhinitis (AR) and nonallergic rhinitis (NAR) patients can elicit nasal hyper-reactivity symptoms. Differences in the prevalence or type of nasal hyper-reactivity in AR and NAR patients are largely unknown. In this study, we quantitatively and qualitatively assessed nasal hyper-reactivity in AR and NAR. METHODS In the first part, an analysis of a prospectively collected database was performed to reveal patient-reported symptoms of hyper-reactivity. In the second part, cold dry air provocation (CDA) was performed as a hyper-reactivity measure in AR and NAR patients and healthy controls, and symptoms scores, nasal secretions and peak nasal inspiratory flow were measured. Comparisons were made between AR and NAR patients in both studies. RESULTS The database analysis revealed high hyper-reactivity prevalence in AR (63.4%) and NAR (66.9%). There were no differences between AR and NAR in terms of the number or type of hyper-reactivity stimuli. Hyper-reactivity to physical stimuli did not exclude a response to chemical stimuli, or vice versa. CDA provocation resulted in a significant increase in rhinitis symptoms and the amount of nasal secretions in AR and NAR patients, but not in controls. CONCLUSIONS We found no quantitative or qualitative differences in nasal hyper-reactivity between AR and NAR patients. It is not possible to differentiate NAR subpopulations based on physical or chemical stimuli.

Abstract
Rhinitis is a common problem in childhood and adolescence and impacts negatively on physical, social and psychological well-being. This position paper, prepared by the European Academy of Allergy and Clinical Immunology Taskforce on Rhinitis in Children, aims to provide evidence-based recommendations for the diagnosis and therapy of paediatric rhinitis. Rhinitis is characterized by at least two nasal symptoms: rhinorrhoea, blockage, sneezing or itching. It is classified as allergic rhinitis, infectious rhinitis and nonallergic, noninfectious rhinitis. Similar symptoms may occur with other conditions such as adenoidal hypertrophy, septal deviation and nasal polyps. Examination by anterior rhinoscopy and allergy tests may help to substantiate a diagnosis of allergic rhinitis. Avoidance of relevant allergens may be helpful for allergic rhinitis (AR). Oral and intranasal antihistamines and nasal corticosteroids are both appropriate for first-line AR treatment although the latter are more effective. Once-daily forms of corticosteroids are preferred given their improved safety profile. Potentially useful add-on therapies for AR include oral leukotriene receptor antagonists, short bursts of a nasal decongestant, saline douches and nasal anticholinergics. Allergen-specific immunotherapy is helpful in IgE-mediated AR and may prevent the progression of allergic disease. There are still a number of areas that need to be clarified in the management of rhinitis in children and adolescents.

Abstract
BACKGROUND Endoscopic sinus surgery (ESS) is considered after medical therapy failure of chronic rhinosinusitis (CRS). The balloon sinuplasty dilates the natural ostium without moving mucosa or bone. It still lacks evidence from randomized controlled trials. The aim of this retrospective controlled study was to compare the symptom outcomes after maxillary sinus surgery with either the ESS or the balloon sinuplasty technique. No previous or additional sinonasal operations were accepted. METHODS Two hundred eight patients with CRS without nasal polyps underwent either balloon sinuplasty or ESS. The patients who met with the inclusion criteria (n = 45 in ESS group and n = 40 in balloon group) replied to a questionnaire of history factors, exacerbations, and a visual analog scale (VAS) scoring of the change in symptoms, on average 28 ± 6 (mean ± SD) months postoperatively. RESULTS The groups were identical in the response rate (64%), patient characteristics, and the improvement in all of the asked symptoms. Patients with CRS-related comorbidity and/or present occupational exposure had a statistically significantly better symptom reduction after ESS than after balloon sinusotomy. Moreover, the balloon sinusotomy group reported a statistically significant higher number of maxillary sinus punctures and antibiotic courses during the last 12 months. CONCLUSION ESS might be superior to balloon sinuplasty, especially in patients with risk factors. There is a need to perform more controlled studies on the treatment choices of CRS.

Abstract
OBJECTIVE Nasal congestion is a common symptom in allergic and nonallergic rhinitis, rhinosinusitis and nasal polyposis. The present study evaluated the clinical effectiveness of Narivent(®), an osmotically-acting medical device with anti oedematous and anti-inflammatory effects, in nasal congestion. METHODS A single-centre, prospective study with a pre- post design and consecutive patient enrolment was conducted in an Italian otolaryngology department. Patients with persistent nasal congestion were allocated to treatment groups as follows: group 1 (n = 36) treated for 7 days; group 2 (n = 56) treated for 30 days. In each group, patients received two puffs of Narivent(®) into each nostril twice daily. Symptom severity was assessed subjectively on a 0-10 visual analogue scale, and objectively by the presence/absence of signs and symptoms. Differences in subjective and objective severity measures before and after treatment were compared using Wilcoxon's signed rank test. RESULTS All symptoms and objective scores improved after treatment with Narivent(®) for 7 or 30 days and no adverse effects were reported by the patients in either group. CONCLUSION Narivent(®) appears to be efficacious in treating nasal congestion over a 7- or a 30-day period.

Abstract
Chronic rhinosinusitis (CRS) is an inflammation of the nose and paranasal sinuses lasting for ≥12 weeks. Endoscopic sinus surgery (ESS) is considered during difficult to treat CRS. The minimally invasive technique focuses on the transition areas rather than on the ostia. The aim of this study was to evaluate symptoms, the number of acute sinusitis episodes, and satisfaction after ESS with either preservation or enlargement of the maxillary sinus ostium. Thirty patients with moderate nonpolypous CRS were enrolled. Uncinectomy only and additional middle meatal antrostomy were randomized for each side of each patient and performed single blindly. The symptoms questionnaires were filled at four time intervals. Significant symptom reduction was achieved independently of operation technique. The number of acute sinusitis episodes indicating the exacerbation rate decreased significantly at 9 and, on average, 68 months postoperatively. However, the exacerbation rate began to increase after 9 months postoperatively. Three revisions were performed on the side with uncinectomy only and one on the side with additional antrostomy. Most patients reported good satisfaction with both procedures. There was a trend for patients with asthma and/or job exposure to report insignificantly more frequently no satisfaction with surgery, especially with the uncinectomy-only procedure. Both procedures seem to be efficient in providing symptom relief and satisfaction. More studies are needed to evaluate if patients with risk factors benefit more from an ostium-enlarging procedure.

Abstract
Chronic rhinosinusitis (CRS) is a complex disease consisting of several disease variants with different underlying pathophysiologies. Limited knowledge of the mechanisms of these disease subgroups is possibly the greatest obstacle in understanding the causes of CRS and improving treatment. It is generally agreed that there are clinically relevant CRS phenotypes defined by an observable characteristic or trait, such as the presence or absence of nasal polyps. Defining the phenotype of the patient is useful in making therapeutic decisions. However, clinical phenotypes do not provide full insight into all underlying cellular and molecular pathophysiologic mechanisms of CRS. Recognition of the heterogeneity of CRS has promoted the concept that CRS consists of multiple groups of biological subtypes, or "endotypes," which are defined by distinct pathophysiologic mechanisms that might be identified by corresponding biomarkers. Different CRS endotypes can be characterized by differences in responsiveness to different treatments, including topical intranasal corticosteroids and biological agents, such as anti-IL-5 and anti-IgE mAb, and can be based on different biomarkers that are linked to underlying mechanisms. CRS has been regarded as a single disease entity in clinical and genetic studies in the past, which can explain the failure to identify consistent genetic and environmental correlations. In addition, better identification of endotypes might permit individualization of therapy that can be targeted against the pathophysiologic processes of a patient's endotype, with potential for more effective treatment and better patient outcomes.

Abstract
BACKGROUND In allergic asthma, the diagnosis of house dust mite (HDM) allergy is mainly based on the patient's history, allergy testing by the skin prick test (SPT) or the levels of allergen-specific IgE. We retrospectively analysed data from 350 bronchial provocations with HDM and related it to the following parameters: specific IgE, bronchial hyperresponsiveness (BHR) to methacholine testing (MCT) and exhaled NO (eNO). METHODS Approximately 350 patients (5-18 yr of age) with allergic asthma and a positive SPT to HDMs were included. To define the sensitivity and specificity for the detection method of an early asthmatic response (EAR), a receiver-operating characteristic (ROC) curve was plotted. The accuracy was measured by the area under the ROC curve (AUC). A logistic regression model was used to predict the individual probability of a positive challenge. The results of the regression model were validated in a prospective group of n = 75 patients. RESULTS The following cut-off values showed the best combination of sensitivity and specificity: specific IgE Dermatophagoides farinae 19.6 kU/l (AUC, 0.88), PD(20) FEV(1) 0.13 mg methacholine (AUC, 0.73) and eNO 20.1 ppb (AUC, 0.71). The following equation predicted the individual probability of a positive challenge in the retrospective and prospective group: p = 1(.) [1 + exp[-(-1.78 + 2.46.(10) log D. far - 1.25(.10) logPD(20) metha)]](-1) , (AUC = 0.88). CONCLUSIONS The value of using the specific IgE and MCT as predictors was confirmed in a large number of patients. We also showed, for the first time, that the eNO predicted the EAR. The logistic regression model is repeatable with a good accuracy.

Abstract
State-of-the-art documents like ARIA and EPOS provide clinicians with evidence-based treatment algorithms for allergic rhinitis (AR) and chronic rhinosinusitis (CRS), respectively. The currently available medications can alleviate symptoms associated with AR and RS. In real life, a significant percentage of patients with AR and CRS continue to experience bothersome symptoms despite adequate treatment. This group with so-called severe chronic upper airway disease (SCUAD) represents a therapeutic challenge. The concept of control of disease has only recently been introduced in the field of AR and CRS. In case of poor control of symptoms despite guideline-directed pharmacotherapy, one needs to consider the presence of SCUAD but also treatment-related, diagnosis-related and/or patient-related factors. Treatment-related issues of uncontrolled upper airway disease are linked with the correct choice of treatment and route of administration, symptom-oriented treatment and the evaluation of the need for immunotherapy in allergic patients. The diagnosis of AR and CRS should be reconsidered in case of uncontrolled disease, excluding concomitant anatomic nasal deformities, global airway dysfunction and systemic diseases. Patient-related issues responsible for the lack of control in chronic upper airway inflammation are often but not always linked with adherence to the prescribed medication and education. This review is an initiative taken by the ENT section of the EAACI in conjunction with ARIA and EPOS experts who felt the need to provide a comprehensive overview of the current state of the art of control in upper airway inflammation and stressing the unmet needs in this domain.

Abstract
The presence of aspirin-exacerbated respiratory disease (AERD) in a patient with chronic rhinosinusitis with nasal polyps and asthma is associated with severe eosinophilic upper and lower airway disease. This article deals with the inflammatory disease of the respiratory tract as it relates to the sinuses. Involvement of the sinuses in AERD is almost universal, depending on the stage of onset of the disease and evaluation by computed tomography. This article explores the clinical aspects, physiopathology, and treatment of rhinosinusitis as it relates to AERD.

Abstract
INTRODUCTION Allergic rhinitis (AR) is a high-prevalence disease, sustained by an IgE-triggered reaction with histamine release, followed by an inflammatory response which involves cells, mediators, cytokines and adhesion molecules. According to its duration, AR can be either intermittent or persistent. In the persistent form, the inflammatory component usually predominates. AREAS COVERED The current therapeutic strategy is based on antihistamines, antileukotrienes and on corticosteroids (which broadly act on inflammation). Allergen-specific immunotherapy is a biological response modifier that affects the immune response to allergens in a broad sense. The available pharmacotherapy is overall effective in controlling symptoms and inflammation, but safety concerns may be present (especially for prolonged treatments), and a proportion of patients remain uncontrolled. The available therapeutic innovations, as derived from the most recent literature are reviewed herein. EXPERT OPINION In the last years there have been very few innovative approaches to optimize the management of AR. These include new histamine receptor antagonists, combination therapy and strategies to selectively block relevant signaling pathways of the allergic reaction. Some more promising advances have been shown for allergen immunotherapy, where a number of new strategies are currently under development.

Abstract
In less than half a century, allergy, originally perceived as a rare disease, has become a major public health threat, today affecting the lives of more than 60 million people in Europe, and probably close to one billion worldwide, thereby heavily impacting the budgets of public health systems. More disturbingly, its prevalence and impact are on the rise, a development that has been associated with environmental and lifestyle changes accompanying the continuous process of urbanization and globalization. Therefore, there is an urgent need to prioritize and concert research efforts in the field of allergy, in order to achieve sustainable results on prevention, diagnosis and treatment of this most prevalent chronic disease of the 21st century.The European Academy of Allergy and Clinical Immunology (EAACI) is the leading professional organization in the field of allergy, promoting excellence in clinical care, education, training and basic and translational research, all with the ultimate goal of improving the health of allergic patients. The European Federation of Allergy and Airways Diseases Patients' Associations (EFA) is a non-profit network of allergy, asthma and Chronic Obstructive Pulmonary Disorder (COPD) patients' organizations. In support of their missions, the present EAACI Position Paper, in collaboration with EFA, highlights the most important research needs in the field of allergy to serve as key recommendations for future research funding at the national and European levels.Although allergies may involve almost every organ of the body and an array of diverse external factors act as triggers, there are several common themes that need to be prioritized in research efforts. As in many other chronic diseases, effective prevention, curative treatment and accurate, rapid diagnosis represent major unmet needs. Detailed phenotyping/endotyping stands out as widely required in order to arrange or re-categorize clinical syndromes into more coherent, uniform and treatment-responsive groups. Research efforts to unveil the basic pathophysiologic pathways and mechanisms, thus leading to the comprehension and resolution of the pathophysiologic complexity of allergies will allow for the design of novel patient-oriented diagnostic and treatment protocols. Several allergic diseases require well-controlled epidemiological description and surveillance, using disease registries, pharmacoeconomic evaluation, as well as large biobanks. Additionally, there is a need for extensive studies to bring promising new biotechnological innovations, such as biological agents, vaccines of modified allergen molecules and engineered components for allergy diagnosis, closer to clinical practice. Finally, particular attention should be paid to the difficult-to-manage, precarious and costly severe disease forms and/or exacerbations. Nonetheless, currently arising treatments, mainly in the fields of immunotherapy and biologicals, hold great promise for targeted and causal management of allergic conditions. Active involvement of all stakeholders, including Patient Organizations and policy makers are necessary to achieve the aims emphasized herein.

Abstract
OBJECTIVES/HYPOTHESIS Demonstration of nasal hyperreactivity (NHR) in allergic and nonallergic rhinitis remains a diagnostic challenge because of the lack of a clinically attractive protocol with high sensitivity and specificity. Our aim was to evaluate the feasibility of a shortened cold dry air (CDA) provocation protocol for the diagnosis of NHR in patients with allergic rhinitis (AR) and idiopathic rhinitis (IR). STUDY DESIGN Twelve AR patients, 12 IR patients, and 12 controls were exposed to air at -10°C and <10% humidity for 15 minutes. METHODS Nasal symptoms were subjectively evaluated by visual analogue scale (VAS), and nasal obstruction was objectively measured by peak nasal inspiratory flow (PNIF) before and after CDA exposure. NHR was defined as a drop in PNIF larger than 20% from baseline upon CDA challenge. RESULTS Nasal CDA exposure induced nasal obstruction in AR and IR patients but not in controls. The VAS for nasal obstruction increased significantly in IR patients (post-CDA: 9.1 cm [6.9, 9.7] vs. pre-CDA: 5.5 cm [5.0, 8.9], P = .004) as well as in AR patients (post-CDA: 5.0 cm [1.3, 6.6] vs. pre-CDA: 0.8 cm [0.0, 1.7], P = .001). PNIF values showed a significant decrease in the AR (post-CDA: 50.0 L/min [37.5, 97.5] vs. pre-CDA: 95.0 L/min [52.5, 127.5], P = .002) and IR (post-CDA: 75.0 L/min [47.5, 102.5] vs. pre-CDA: 100.0 L/min [67.5, 130.0], P = .002) group after CDA provocation, which was not observed in the controls (P = 1.000). The sensitivity and specificity of CDA provocation for diagnosis of NHR were 66.7% and 100%, respectively, for both IR and AR. In contrast to nasal obstruction, rhinorrhea and sneezing were not induced by CDA exposure. CONCLUSIONS This study demonstrates that a short nasal CDA exposure is a reliable method for the diagnosis of NHR in rhinitis patients, with a high sensitivity and specificity.

Abstract
BACKGROUND The mechanisms underlying conjunctival symptom reduction by nasal corticosteroids in allergic rhinoconjunctivitis are unknown. A naso-ocular reflex may be present. OBJECTIVE To study the effects of nasal fluticasone furoate (FF) on conjunctival symptoms and substance P and histamine levels in tear fluid after nasal grass pollen provocation (GPP). METHODS A double-blind placebo-controlled study was performed in 26 grass pollen-allergic patients. A selective GPP was performed during the grass pollen season after 2 weeks of FF or placebo treatment. Nasal and conjunctival symptoms were scored using a visual analog scale (VAS), and tear fluid was collected for measuring substance P and histamine using an enzyme-linked immunosorbent assay. RESULTS Compared with placebo, FF reduced conjunctival symptom scores during the pollen season (-1.75 [-2.75, 0.20] vs 0.0 [0.0, 0.0]; P = .01) and after GPP at 15 minutes (0.05 [-0.42, 1.52] vs 2.05 [0.62, 3.62]; P < .001) and 1 hour (-0.45 [-1.75, 0.1] vs 0.05 [-0.97, 1.85]; P < .01). Treatment with FF decreased substance P levels in tear fluid (44.11 [32.81, 61.02] vs 65.26 [48.62, 79.73] pg/mg protein; P = .0098). Histamine levels in tear fluid showed a GPP-induced increase in the placebo group (7.26 [3.12, 9.69] vs 5.71 [2.05, 7.00] ng/mg protein; P = .02), but not in the FF group (6.77 [3.43, 13.00] vs 5.24 [3.18, 7.06] ng/mg protein; P = .08). CONCLUSION FF nasal spray reduced conjunctival symptoms in grass pollen-allergic patients in parallel with lower substance P levels in tear fluid. These data help in understanding the reduction of conjunctival symptoms by intranasal anti-inflammatory therapy.

Abstract
Olfaction is an essential chemosensory system in the living world. Although less appreciated in humans, smell impairment significantly affects many aspects of quality of life. Smell disorders may be caused by an impaired nasal airway or by lesions in the olfactory system, leading to reduced or distorted smell perception. The most common causes of smell disorders are aging, upper respiratory tract infection, sinonasal disease, and head trauma. Recovery is rarely complete. Counseling is important in progressive or severe smell loss. In patients with distorted smell perception, antidepressant medication is sometimes necessary. Best response to treatment is achieved for nasal obstruction and sinonasal inflammatory disease. Treatment of olfactory impairment caused by sinonasal disease includes medication with topical and systemic steroids, or surgery for refractory cases. Although there are reports that surgical resection of olfactory neurons may lead to reinnervation and recovery of smell, adequate treatment of the smell loss remains an unmet need.
