Abstract
Acute rhinosinusitis and chronic rhinosinusitis are inflammatory diseases of the mucosal membranes due to mislead immunological reactions to aeroallergens. T‑cells are divided into different groups based on their cytokine secretion: T‑helper type 1 (Th1) and type 2 (Th2) cells. The allergic immune response is caused by activation of specific Th2 cells. With specific immunotherapy, the mislead hyperactivated "allergic" immune response is reduced to a reaction within the normal range. The inflammatory forms of chronic rhinosinusitis are called endotypes, and, in the future, could enable a targeted, pathomechanistic therapy. These endotype-based treatment approaches target specific signaling pathways that have already shown good effects for chronic rhinosinusitis with nasal polyps using monoclonal antibodies. However, so far, only selected patients with non-rhinologic indications, off-label treatments, or in clinical trials have benefited from these treatments.

Abstract
Nasal polyposis, occurring in about 2% of the general population, is the ultimate form of inflammation of the upper airways. For unknown reasons, polyps develop preferentially in subtypes of inflammatory diseases and are associated with perennial non-allergic rhinitis, asthma, intolerance of aspirin (acetylsalicylic acid)/NSAIDs, allergic fungal rhinosinusitis, cystic fibrosis, and primary ciliary dyskinesia. In contrast to common beliefs, IgE-mediated allergy does not seem to play an etiological role in nasal polyposis.The polyps originate from the mucosa around the clefts of the lateral nasal wall, especially in the region of the ostiomeatal complex. The factors that determine the localization of the disease to a few square centimeters of the airways are not known.Polyps are edematous bags covered by respiratory epithelium and contain very few nerves, blood vessels, and glands that have undergone cystic degeneration. They contain degranulated mast cells, have a very high concentration of histamine, and are characteristically infiltrated by eosinophils. These cells accumulate due to the release of proinflammatory cytokines (in particular, interleukin-5).Nasal polyposis is preceded by a prolonged history of rhinitis accompanied by severe and persistent nasal blockage; typically, the sense of smell is seriously impaired when polyps develop. The diagnosis is based on anterior rhinoscopy or, preferably, endoscopy.Nasal polyposis is medically treatable. Surgical treatment is carried out when medication fails. Intranasal corticosteroids reduce rhinitis symptoms, improve nasal breathing, reduce the size of polyps, and prevent, in part, their recurrence, but this treatment has little effect on the sense of smell. Intranasal corticosteroids can, as basic long-term therapy, be used alone in mild cases or together with systemic corticosteroids and/or surgery in severe cases. Systemic corticosteroids administered for 2-3 weeks have a beneficial effect on all observed symptoms and pathology, including the sense of smell. When nasal blockage is a problem in spite of medical treatment, surgery is recommended. Simple polypectomy can be performed, but endoscopic surgery is recommended in more severe and persistent cases.

Abstract
OBJECTIVES/HYPOTHESIS Although medical intervention is the first option for treatment of nasal polyps, surgery is still a therapeutic option for symptomatic cases that do not respond or partially respond to medical intervention. However, there is a need for high-level evidence for the preoperative use of steroids in nasal polyposis surgery. We aimed to assess the perioperative effect of preoperative use of oral prednisolone for advanced-stage diffuse nasal polyposis. STUDY DESIGN Prospective, double-blind, randomized, placebo-controlled study. METHODS A visual analog scale (VAS) was evaluated for smell, nasal discharge, nasal obstruction, facial pressure, headache, butanol smell threshold, and peak nasal inspiratory flow (PNIF) before and after the use of study drug. Perioperative bleeding volume, visibility of operative field, operative time, hospital stay, and complication rate were also evaluated. RESULTS The improvement in the corticosteroid group (CG) in the VAS scores, butanol thresholds, and PNIF values showed statistically significant differences compared to the placebo group (PG) (P < .05). The perioperative bleeding volume, visibility score, operative time, and hospital stay for CG/PG were 141 mL/384 mL, 2.4/3.4, 61 min/71.6 min, and 1.1 day/1.8 day, respectively (P < .05). The difference between the complication rates for the two groups did not show any statistically significant difference (P = .214). CONCLUSIONS Preoperative administration of systemic corticosteroids improves the perioperative visibility by reducing blood loss and shortens the operation time. We recommend the use of preoperative corticosteroid for the safety of the patients. The optimum dose and duration have not been established and require further studies. LEVEL OF EVIDENCE 1b.

Abstract
For several years there has been discussion of whether first-line pharmacological treatment of allergic rhinitis should be antihistamines or intranasal corticosteroids. No well documented, clinically relevant differences seem to exist for individual nonsedating antihistamines in the treatment of allergic rhinitis. Likewise, the current body of literature does not seem to favor any specific intranasal corticosteroid. When comparing efficacy of antihistamines and intranasal corticosteroids in allergic rhinitis, present data favor intranasal corticosteroids. Interestingly, data do not support antihistamines as superior in treating conjunctivitis associated with allergic rhinitis. Safety data from comparative studies in allergic rhinitis do not indicate differences between antihistamines and intranasal corticosteroids. Combining antihistamines and intranasal corticosteroids in the treatment of allergic rhinitis does not provide additional beneficial effects to intranasal corticosteroids alone. Considering present data, intranasal corticosteroids seem to offer superior relief in allergic rhinitis, when compared with antihistamines.

Abstract
OBJECTIVE To investigate the effect of fluticasone propionate (FP) on the symptom of nasal obstruction and to assess the correlation between the subjective visual analogue score (VAS) and the objective acoustic rhinometry (AR) measurements. METHODS A prospective study of 45 consecutive patients, 30 males and 15 females with a mean age of 27 years (range: 16-59 years), with moderate/severe symptoms of perennial rhinitis who were treated by FP nasal spray for 4 weeks. AR and VAS were used to evaluate, compare and correlate the efficacy of FP nasal sprays. RESULTS There was a significant improvement in the VAS post-treatment (3.9) compared with pre-treatment (6.3). There was also a significant increase in the nasal volume (V) and minimum cross-sectional area (MCA) after intranasal FP. Good correlation between the total MCA and total V was noted. Subjective improvements in symptoms did not correlate well with objective measurements as the correlation between VAS and AR was poor. CONCLUSION Our study provides subjective and objective evidence on the efficacy of intranasal FP in improving nasal obstruction in perennial rhinitis. AR also proved to be a useful instrument in monitoring the effectiveness of medical therapy for perennial rhinitis.

Abstract
Intranasal corticosteroids are accepted as safe and effective first-line therapy for allergic rhinitis. Several intranasal corticosteroids are available: beclomethasone dipropionate, budesonide, flunisolide, fluticasone propionate, mometasone furoate, and triamcinolone acetonide. All are efficacious in treating seasonal allergic rhinitis and as prophylaxis for perennial allergic rhinitis. In general, they relieve nasal congestion and itching, rhinorrhea, and sneezing that occur in the early and late phases of allergic response, with studies showing almost complete prevention of late-phase symptoms. The rationale for topical intranasal corticosteroids in the treatment of allergic rhinitis is that adequate drug concentrations can be achieved at receptor sites in the nasal mucosa. This leads to symptom control and reduces the risk of systemic adverse effects. Adverse reactions usually are limited to the nasal mucosa, such as dryness, burning and stinging, and sneezing, together with headache and epistaxis in 5-10% of patients regardless of formulation or compound. Differences among agents are limited to potency, patient preference, dosing regimens, and delivery, device and vehicle.

Abstract
Whether first-line pharmacological treatment of allergic rhinitis should be antihistamines or intranasal corticosteroids has been discussed for several years. First-generation antihistamines are rarely used in the treatment of allergic rhinitis, mainly because of sedative and anticholinergic adverse effects. On the basis of clinical evidence of efficacy, no second-generation antihistamine seems preferable to another. Similarly, comparisons of topical and oral antihistamines have been unable to demonstrate superior efficacy for one method of administration over the other. Current data documents no striking differences in efficacy and safety parameters between intranasal corticosteroids. When the efficacy of antihistamines and intranasal corticosteroids are compared in patients with allergic rhinitis, present data favours intranasal corticosteroids. Interestingly, data do not show antihistamines as superior for the treatment of conjunctivitis. Safety data from comparative studies in patients with allergic rhinitis do not indicate differences between antihistamines and intranasal corticosteroids. Combining antihistamines and intranasal corticosteroids in the treatment of allergic rhinitis does not provide any additional effect to intranasal corticosteroids alone. On the basis of current data, intranasal corticosteroids seem to offer superior relief in allergic rhinitis than antihistamines.

Abstract
Nasal polyps are the common end-point of a number of conditions characterised by inflammation and are rarely 'curable' in its true sense. After consideration of the underlying aetiology and confirmation of the diagnosis, they are normally managed by a combination of medical and surgical interventions. Of these, topical corticosteroids have proved to be the medical treatment of choice. The objectives of the medical management are to eliminate or reduce the size of polyps, re-establish nasal airway and nasal breathing, improve or restore the sense of smell, and prevent recurrence of nasal polyps. The mechanism of action of corticosteroids may be by a multifactorial effect on various aspects of the inflammatory reaction, the effect being initiated by their binding to a specific cytoplasmic glucocorticoid receptor. At a cellular level, there is a reduction in the number of antigen-presenting cells, in the number and activation of T cells, in the number of mast cells, and in the number and activation of eosinophils. When polyps are large (grade 3) topical medication is difficult to instil in a very blocked nose and surgery or short term systemic corticosteroids may be required. Topical corticosteroids are of use in the primary treatment of nasal polyps when they are of a small or medium size (grades 1 and 2) and in the maintenance of any therapeutic improvement. The efficacy of topical corticosteroids such as betamethasone sodium phosphate nose drops, beclomethasone dipropionate, fluticasone propionate and budesonide nasal sprays in reducing polyp size and rhinitis symptoms has been demonstrated in several randomised, placebo-controlled trials. Beclomethasone dipropionate, flunisolide and budesonide sprays have also been shown to delay the recurrence of polyps after surgery. Placebo-controlled studies of agents that have shown a significant clinical effect in the management of nasal polyposis are reviewed.

Abstract
Topical administration of corticosteroids can reduce the total dose of corticosteroid required to treat the patient and minimize side effects. This logic has led to the development of intranasal corticosteroids (INCS) for allergic and perennial rhinitis. The second generation of these compounds includes beclomethasone dipropionate, budesonide, flunisolide, fluticasone propionate, mometasone furoate, and triamcinolone acetonide. There is evidence that the INCS are effective in rhinitis; however, there is concern about the potential for these compounds to cause growth suppression. In one study, beclomethasone dipropionate significantly reduced growth in children; however, treatment of children with mometasone furoate nasal spray for 1 year showed no signs of growth suppression. It is evident that the differences among INCS lie in their pharmacokinetics. Structural differences among the various INCS influence their metabolism. The goal of INCS therapy is to have a high ratio of topical to systemic activity. The drug delivery device, absorption of the drug, and drug distribution all contribute to effective topical activity of an INCS. In addition, individual drug metabolism and elimination (half-life and drug clearance) also contribute to the therapeutic index of a drug. Overall, the second-generation INCS cause minimal systemic effects at recommended doses.

Abstract
The mode of action of intranasal corticosteroids (INCS) is complex. It is not known whether INCS penetrate the nasal mucosa or act on target cells; however, their low systemic activity supports the concept of local action on nasal mucosa. This local effect can nonetheless influence a variety of inflammatory cells and their mediators such as epithelial cells, lymphocytes, basophils, mast cells, and Langerhans cells. Corticosteroid-induced inhibition of immunoglobulin E-dependent release of histamine is a possible but unproven mode of action. Epithelial cells are an important target for corticosteroids, and INCS concentration is high at the epithelial surface. INCS may combine with the corticosteroid receptors in epithelial cells, which are then expelled into the airway lumen together with the dead epithelial cells or migrating inflammatory cells. A reduced influx of mediator cells may explain some of the effects of INCS on rhinitis symptoms, but it cannot explain all of the effects because INCS also reduce the early-phase sneezing and rhinorrhea after an allergen challenge outside the pollen season. In this situation, the number of surface mast cells/basophils is very low, as it is in the absence of allergic rhinitis. The mechanism by which INCS treatment of allergic rhinitis reduces itching, sneezing, and rhinorrhea, the characteristic symptoms of an early-phase response involving mast cell release of histamine, remains to be determined. Studies should be conducted to characterize the broad range of mechanisms by which INCS produce their therapeutic effects in allergic rhinitis.

Abstract
The rheological profiles of four commercial nasal spray suspensions (Beconase, Flixonase, Nasacort and Nasonex) were compared using rotational viscometry. Two of the nasal sprays (Beconase and Nasonex) were further examined in both shear and extension using a capillary rheometer under conditions similar to those experienced at the spray nozzle (i.e. extremely high shear rates with significant stretching or extensional flow). In rotation, the shear viscosity fell rapidly with increase in shear rate. Plots of the viscosity derived at the lower shear rates in rotation were extrapolated to include the high-shear rate capillary values. At very high shear rates, the shear viscosity of Beconase was higher than that of Nasonex with the cross-over occurring in the extrapolated region at approximately 10,000 s(-1). In the transition region between laminar and turbulent flow (shear rate 6-8 x 10(4) s(-1)) there was a minimum in the shear viscosity to less than that of water for Nasonex and similar to water for Beconase, and a plateau region in extensional viscosity for Beconase but not Nasonex. These anomalies were due to the extensive aeration of both samples when sprayed. Whereas Beconase had de-aerated within 30 min of the experiment, Nasonex had not de-aerated completely after six weeks. The very low viscosity at the shear rates at the nozzle imply that it is unlikely that the low viscosity of the spray on delivery to the nose is a key factor in prolonging its residence time. The extensional viscosity for these rather fluid samples was over 1000-times the shear viscosity (not 3-times as with Newtonian fluids) and both sprays exhibited strain hardening over the range covered. The high extensional stress in the nozzle enables the fluid to form as reasonably sized droplets rather than fine atomized droplets, which rather than settling in the nose, would be prone to redistribution through the normal respiratory function. Both sprays resisted degradation despite the high shear rates and extensional stresses experienced.

Abstract
The rheological profiles of commercial corticosteroid nasal spray suspensions (Beconase, Nasacort, Flixonase, and Nasonex) were compared using shear and extensional techniques. Thixotropy/shear thinning was investigated (Carri-Med CSL100, concentric cylinder geometry) by (a) the generation of flow curves at low (100 sec-1) and high (1200 sec-1) maximum shear rates and (b) determination of equilibrium shear viscosities at constant shear rates of 10 sec-1, 100 sec-1, or 1200 sec-1. Extensional properties, on which droplet breakup and size depend, were examined using digital camera photography of droplet evolution and the length any trailing filament formed when the suspension was extruded from a 10-ml syringe at 500 microliters/min. All the nasal suspensions were shear thinning and were also thixotropic to varying degrees. The absence of significant thixotropic recovery at short times (5 min) for all the sprays implies that thixotropy is not necessarily the controlling factor for prolonged residence of the spray in the nasal cavity, but rather that it is the high viscosities present in all four sprays, even after structure breakdown. Preliminary extensional flow data identified differences among the four sprays, with extensional filament lengths increasing in the same rank order as the lowest shear rate (10 sec-1) equilibrium viscosities.

Abstract
The aim of this study was to evaluate the influence of five intranasal applications of capsaicin, performed after endoscopic polypectomy associated with partial middle turbinectomy and anterior ethmoidectomy, on the recurrence of nasal polyps and the intensity of nasal obstruction and rhinorrhea. Fifty-one patients (19 females, 32 males, mean age 43 years) suffering from nasal polyposis for more than 1 year were included in this double blind, randomized, placebo-controlled study. During post-surgical controls, local anaesthesia and vasoconstriction of the middle meatus area were performed in all patients with a cotton pellet soaked with lidocain and adrenaline. In 29 patients, the same type of cotton pellet soaked with capsaicin (3 x 10(-6) mol. dissolved in 70% ethanol) was left into the middle meatus of both nostrils for 20 min. As a control group, 22 patients, matched for age and sex, were treated with the capsaicin vehicle alone (70% ethanol). All patients studied received the intranasal treatment once a week for 5 weeks. Subjective evaluations of nasal airway resistance (NAR) and rhinorrhea were recorded by means of a visual analogue scale. Clinical staging of the nasal polyposis (graded from stage 0 = absence of polyp to stage 3 = polyps occupying the entire nasal cavity) was evaluated by the same ENT specialist (ZW) using a 0 degrees endoscope. All parameters were recorded for each patient 1 week before surgery, then once a month for 9 months. Patients treated by endoscopic surgery followed by intranasal capsaicin application, reported a marked reduction in their NAR compared with the pretreatment evaluation (p<0.001). In contrast, patients treated with the vehicle alone did not have any significant improvement of their subjective NAR. Subjective rhinorrhea was not modified by either treatment. Patients treated with capsaicin showed a significant smaller staging of their nasal polyposis compared with the control group (p<0.001). These observations suggest that endoscopic surgery followed by intranasal capsaicin application reduces polyps and nasal obstruction recurrence and could be an alternative treatment to expensive corticosteroids in developing countries.

Abstract
The standard treatment of allergic rhinitis and asthma consists of topical corticosteroids administered intranasally and inhaled through the mouth. Although this therapy is highly effective, and side-effects are few and mild, it may be possible further to improve the therapeutic index and patient compliance with the treatment. In the present study, we evaluated a nasal inhalation system used for the simultaneous treatment of rhinitis and asthma. In principle, it results in an airway deposition of the corticosteroid similar to that of inhaled allergens. Twenty-four children with perennial rhinitis and asthma inhaled budesonide through the nose from a pressurized aerosol, attached to a spacer device, in a double-blind, placebo-controlled, crossover study. Compared with placebo, budesonide treatment resulted in a significant reduction of nasal symptoms (P<0.01) and of asthma symptoms (P<0.05), and in an increase of nasal peak inspiratory flow (P < 0.001) and of oral peak expiratory flow (P=0.01). There were no differences between budesonide and placebo in local side-effects, such as dry nose, nosebleed, and hoarseness. We conclude that nasal inhalation of a corticosteroid from a spacer offers a simple and effective treatment for both rhinitis and asthma in children, but it is an open question whether the nasal inhalation system can improve the ratio of antirhinitis/antiasthma effects to side-effects.

Abstract
This paper gives an overview of placebo-controlled studies of the effect of corticosteroid treatment on nasal blockage, based on objective measurements of nasal airway patency. A few studies of perennial rhinitis have indicated that pretreatment with an intranasal corticosteroid has a moderate effect on nasal hyperresponsiveness, measured as the histamine-induced increase of nasal blockage. Whereas the effect on allergen-induced early-phase symptoms is variable, the effect on the late-phase blockage is almost complete. In seasonal allergic rhinitis, a few studies have shown an effect of intranasal steroids on nasal airway resistance, nasal peak flow and on acoustic rhinometry, but there are no reports on the effect in adults with perennial rhinitis. In children with perennial disease, intranasal treatment results in increased nasal patency and, in one study, also in reduced mouth breathing and in an increased threshold for exercise-induced bronchoconstriction. In patients with nasal polyposis, intranasal steroids have an effect on nasal airway resistance and on nasal peak flow both before and after polypectomy. There is convincing evidence that intranasal corticosteroids provide a better effect than antihistamine on nasal blockage. Amazingly, there does not appear to be any report on the effect of systemic corticosteroid treatment on nasal airway patency, and it is therefore difficult to recommend this treatment in a rational dosage. In conclusion, there is a fairly good documentation in support of the efficacy of intranasal steroid treatment on nasal airway patency in rhinitis. An objective measurement of nasal airway patency ought to be the routine in controlled rhinitis trials.
