The term "local allergic rhinitis" has gained popularity as a clinical entity in recent years. Despite the apparent contradiction in the definitions of "nasal" and "local," we offer insights based on our extensive experience in the field. Local allergic rhinitis has been recognized and treated for many years, so it is not a new discovery. The nasal provocation test, which was introduced in the 1980s, was critical in identifying allergic rhinitis cases with suggestive symptoms but negative allergy tests. Our reflections aim to contribute to a precise terminological decision that is consistent with various points of view., (Copyright © 2023, the Author(s).)

Rhinosinusitis (RS) is a common disease and is currently classified into two main types: acute RS (ARS) and chronic RS (CRS), which in turn includes CRS with or without nasal polyps. Different guidelines consider this classification. However, in clinical practice, other phenotypes exist. The current article would propose new clinical-based phenotyping of RS, including the following clinical phenotypes: simple catarrhal RS, Acute RS, acute bacterial RS, severe (complicated) acute RS, chronic RS, and recurrent chronic RS. Treatment strategy should be tailored considering the clinical phenotype and could include phytomedicines, intranasal non-pharmacological remedies, and local bacteriotherapy. In conclusion, RS requires thorough diagnostic work-up, and the therapeutic approach should be mainly based on appropriate management.

The COVID-19 pandemic era is causing a relevant issue for the health. There is no specific drug able to antagonize the SARS-CoV-2 infection. As a consequence, there is growing interest about potential molecules able to contrast infection. In this regard, HMGB, an alarmin, may play a relevant role in pathogenic mechanisms induced by SARS-CoV-2.  As HMGB1 is antagonized by glycyrrhizin, this substance could be potentially useful as ancillary treatment in COVID-19.

Background A randomized, double-blind placebo-controlled study investigated the use of bacteriophages in the treatment of chronic rhinosinusitis with nasal polyps. Materials and Methods 40 adult patients with сhronic rhinosinusitis with nasal polyps were examined. All patients underwent functional endoscopic sinus surgery. After the surgery, 20 patients got the intranasal gel with a bacteriophages mixture (Otofag, Micromir, Russia) twice a day for ten weeks, and 20 patients got a placebo. Results On the 10th day, IL-1β secretion diminished (63 mg/ml versus 440 mg/ml in control). There was a decrease in the total number of microorganisms and Enterobacteriaceae (5.7 x 106 CFU/ml versus 1.2 x 109 CFU/ml in control), and the absence of Streptococci (versus 2.1 x 109 CFU/ml in control) on the 30th day of the treatment in the group with the bacteriophages. On the 10th day, a decrease in the activity of secretory IL-1β and IL-8 strongly and very strongly correlated with a total number of microorganisms (r = 0.7; r = 0.9 respectively), as well as secretory IL-8 with Enterobacteriaceae (r = 0.72) and Staphylococci (r = 0.65) in the active group treated with the bacteriophages. On the 30th day, the decrease in serum IL-1β significantly correlated with the total number of microorganisms (r = 0.80) and enterobacteria (r = 0.90) in the active group. Conclusions The administration of bacteriophages restored the balance of microorganisms in the nasal cavity and decreased the inflammatory response in chronic rhinosinusitis with nasal polyps. These changes, such as an inflammation dampening, could theoretically reduce the recurrent growth of polyp tissue in the future.

In the pandemic coronavirus disease 2019 (COVID-19) era, the need to use preventive-curative treatments is compelling. A series of non-pharmacological compounds, including oligo-elements, vitamins, nutraceuticals, and bacteriotherapy, might affect the risk of COVID-19, both reinforcing the immune system and improving the inflammation resolution during respiratory infections. Non-pharmacological remedies are very popular and usually have no relevant side effects. Bacterial and natural products may potentiate the immune system against respiratory viruses. Moreover, these compounds also exert antiinflammatory and antioxidant activity. Consequently, these non-chemical remedies could be prescribed to build up the immune defence and adequately treat the upper respiratory infection. In this way, natural compounds could be used to manage people in the pandemic COVID-19 era., (Copyright 2020 Biolife Sas. www.biolifesas.org.)

Pseudomonas aeruginosa is an opportunistic human pathogen that frequently induces antibiotic resistance, as it mainly tends to form biofilms. Iron chelation may be an intriguing strategy to contrast bacterial growth. Lactoferrin is a natural compound able to chelate iron. A new multi-component medical device also contains lactoferrin. This study analyzed this compound investigating the in vitro capacity to inhibit Pseudomonas aeruginosa growth. In conclusion, this study demonstrated that a multicomponent medical device (Saflovir), also containing lactoferrin, could inhibit the in vitro growth of P. aeruginosa . This activity could be positively used in the prevention of respiratory nasal infections., (Copyright 2020 Biolife Sas. www.biolifesas.org.)

Laryngopharyngeal reflux (LPR) is an inflammatory reaction of the mucosa of the pharynx, larynx, and other associated upper respiratory organs, caused by a reflux of stomach contents outside the esophagus. LPR is considered a relatively new clinical entity with a vast number of clinical manifestations that are sometimes treated empirically and without a correct diagnosis. Alginate is a reasonable therapeutic option as a first-line or add-on option. A survey included 35 Italian otorhinolaryngologists. The survey considered ten practical queries. LPR is a common disease in clinical practice. History and fiber-optic endoscopy constitute the main diagnostic tools. Alginates represent a frequent medication to treat LPR both as first-line and add-on. The mean effectiveness rate is 44% for first-line choice and 76% for the add-on. In conclusion, the current survey provided exciting information about the management of LPR in clinical practice., (Copyright 2020 Biolife Sas. www.biolifesas.org.)

Introduction: High mobility group protein box 1 (HMGB1) is a protein belonging to the alarmin family. HMGB1 has a relevant role in starting the inflammatory cascade by means of receptors, such as RAGE and TLR. HMGB1 supports transcription of many genes in interactions with many transcription factors, including NF-kB. The axis HMGB1-RAGE-NF-kB has, therefore, a pivotal role in the inflammatory cascade. HMGB1 controls the production of several pro-inflammatory cytokines and the proliferation and activation of many inflammatory cells., Areas Covered: The present report concerns the role of HMGB1 in nasal inflammatory disorders, including allergic and non-allergic rhinitis, and chronic rhinosinusitis with nasal polyps. HMGB1 modulation has been the aim of several studies. The literature search included recent papers that covered this topic., Expert Opinion: As HMGB1 has a pivotal role in inflammatory events, its modulation could be attractive for designing new therapeutic strategies. In this regard, glycyrrhetic acid (GA), the active component of Glycyrrhiza glabra , can efficiently block HMGB1. Promising reports seem to suggest that GA could exert favorable anti-inflammatory activity in patients with nasal inflammatory disorders.

Allergic rhinitis (AR) is a very common disorder. The current Survey was conducted on a sample of about 5,000 adult subjects in 5 Italian cities. A questionnaire, containing 15 questions, was administered on the road. AR affects about 20% of the general population. The most common diagnostic test was the skin prick test, but only 12% of patients performed an allergy test to confirm the diagnosis. About 50% of patients did not take any medicine. Even about 40% of treatments were suggested by friends or pharmacists. In conclusion, the current Survey demonstrated that AR is a common disorder in Italy, the diagnostic work-up is still incorrect, and the therapeutic approach does not adhere to the guidelines. Therefore, there is a need to implement adequate information on this topic in Italy.

Allergic rhinitis (AR) is caused by an IgE-mediated inflammatory reaction consequent to the exposure to the causal allergen. Glycyrrhetic acid (GlyAc) is a natural compound extracted from the liquorice that exerts anti-inflammatory activity. This real-life study compared intranasal GlyAc, present in a medical device containing also glycerol and mannitol, with mometasone furoate nasal spray (MFNS) in 50 adult outpatients with AR. Both treatments lasted 2 months. Endoscopic signs, perception of symptom severity, assessed by VAS, and nasal function measured by rhinomanometry were evaluated at baseline (T0), after one (T1) and two (T2) months. The intergroup analysis showed that at T1 there was no significant difference between groups about the use of decongestants and antihistamines, turbinate hypertrophy and pale mucosa, perception of olfaction and snoring. At T2 there was no significant difference between groups about use of relievers, all endoscopic signs, and perception of nasal discomfort, nasal obstruction, olfaction, and snoring. The intragroup analysis showed that in MFNS group there was a significant change during the entire period of treatment for all parameters except watery rhinorrhea (sign) and ocular discomfort; in GlyAc group there was a significant change during the entire period of treatment for all parameters. In conclusion, this preliminary study, conducted in clinical practice, evidenced that intranasal CysAC plus mannitol was able to significantly improve nasal endoscopic signs, perception of symptoms, and nasal function in patients with AR. Therefore, GlyAc could be a reasonable therapeutic option to control allergic inflammation.

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a frequent disorder. From a clinical and an immunopathological point of view, different phenotypes and endotypes have been identified. The frequent comorbidity with asthma allowed to pave the way to the use of biological agents for the treatment of CRSwNP. Biological agents are targeted to antagonize IgE, interleukin (IL) 4, IL-5, and IL-13 at present. However, a correct and appropriate workup is mandatory, mainly concerning the exact definition of the specific pheno-endotype. The preliminary outcomes are promising, even though there is a need for well-established indications, criteria of responsiveness, duration, and safety. On the other hand, this personalized medicine could be fruitfully integrated with gold-standard medications, such as intranasal corticosteroids. As CRSwNP is a chronic disorder, treatment should be long-lasting, so complementary anti-inflammatory treatments could be opportunely integrated and/or alternated to steroids.

Objective: Nasal administration of Streptococcus salivarius 24SMB and Streptococcus oralis 89a has been proposed to reduce the risk of new episodes of adenoiditis, tonsillitis and acute rhinosinusitis in children., Patients and Methods: We enrolled 202 children with a recent diagnosis of recurrent upper respiratory tract infection. All the patients were treated twice daily for 7 days each month for 3 consecutive months with a nasal spray whose active agents were two specific bacterial strains: Streptococcus salivarius 24SMB and Streptococcus oralis 89a. Evaluation was performed at the end of treatment and at follow-up at 3, 6, and 12 months., Results: Patients who completed the entire 90-day course of bacteriotherapy and the follow-up period showed a 64.3% reduction in their episodes of upper respiratory tract infections compared to the number of episodes recorded in the previous year. Treatment decreased the reported incidence of infection events by 52.4% in the first 3 months, 31.2% at 6-month follow-up, and 20.8% after 12 months. Enrolled patients tolerated the product well, and there were no dropouts., Conclusions: Prophylactic bacteriotherapy by administration of Streptococcus salivarius 24SMB and Streptococcus oralis 89a in children with a history of recurrent upper respiratory tract infection could reduce the number of episodes of otolaryngologic infections. Bacteriotherapy can be even more clinically important due to increasing difficulty in finding new effective antibiotic compounds. New alternative therapeutic approaches must be found with, in comparison to antibiotics, greater specificity and safety with respect to patients' native beneficial flora; lack of drug interactions; the ability to leverage complementary systemic modes of action; and drastically reduced risk of developing resistance within the patient population and the environment.

Objective: The aim of this review is to describe the most common recurring and chronic upper respiratory tract infections (URTI) in children and discuss the role of bacterial interference and bacteriotherapy in their prevention and treatment., Materials and Methods: A literature review has been performed on the following topics: acute otitis media, adenoiditis, tonsillitis, rhinosinusitis, microbiotics and the role of bacterial interference, and bacteriotherapy in the prevention and treatment of URTI., Results: Research studies into the characteristics of the microbiological flora and its role in the pathogenesis of URTI have focused on a single pathogen, on resistance to and ineffectiveness of antibiotic therapies, or on the persistence of bacterial biofilm. Recent evidence supports a central role of the existing microbial ecosystem in the pathogenesis of respiratory disease. In light of this, new therapeutic approaches include the implantation and persistence within the normal microflora of relatively innocuous "effector" bacteria that can competitively exclude or prevent the outgrowth of potentially disease-causing bacteria. Recently, a retrospective and observational study demonstrated that S. salivarius 24SMB and S. oralis 89a nasal spray could be effective in the prevention of recurrent otitis media in a real-life setting. Other studies have focused on the role of bacteriotherapy in children with beneficial effects in the prevention of URTI., Conclusions: The results of previous studies on the role of bacteriotherapy in paediatric URTI suggest that the use of bacterial interference phenomena through bacteriotherapy is a feasible, safe approach and deserves proper consideration as a promising therapeutic strategy against URTI.

Objectives: The purpose of this prospective study was to assess the effectiveness and safety of Streptococcus salivarius 24SMBc administered as a nasal spray in children affected by recurring infections of the upper airways, adenotonsillar hypertrophy, and sleep disordered breathing (SDB)., Methods: Prospective study on 42 children with SDB. Anamnestic and general examination data were collected using the 'Sleep Clinical Record' (SCR) questionnaire during the first inspection and after three months of treatment with Streptococcus salivarius 24SMBc nasal spray. Quantitative variables were statistically compared., Results: After three months, the enrolled patients showed lower SCR scores than during the first inspection (6.0 vs 7.5 p < 0.000), with a significant reduction of nasal obstruction (p = 0.001) and oral breathing (p = 0.04), and a positive Brouillette Score (p = 0.001). The children and parents did not declare any adverse reactions during the three months of treatment., Conclusions: This series confirms the effectiveness and safety of Streptococcus salivarius 24SMBc treatment in children affected by recurring upper respiratory tract infections, adenotonsillar hypertrophy, and sleep disordered breathing., (Copyright © 2018.

Summary: The aim of this research is to investigate penetration of Bromelain into sinonasal mucosa in patients with chronic rhinosinusitis (CRS) versus a control group. Bromelain is derived from pineapple (Ananas comosus) and has various pharmacological effects. 40 patients (20 patients and 20 controls) were enrolled in the study. Bromelain 500 mg tablet twice daily was administered for 30 days. We scored bromelain presence in turbinate and ethmoid mucosas and in the serum of both the groups. Bromelain has an excellent distribution from blood to rhinosinusal mucosa. Its diffusion ability may allow the use of bromelain as an anti-inflammatory agent in paranasal sinus pathologies., (Copyright © 2018 Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.)

Background: Mucociliary clearance is the main self-clearing system of the nasal cavity and paranasal sinuses.This is a very important means of non specific defence against continuous organic and inorganic contamination conveyed by air. It works by trapping particles and microorganisms in the mucus and then by transporting the mucous film to the pharynx where it is eliminated with a cough or swallowed. Its congenital or acquired abnormalities are involved in the occurrence of widespread infectious and often severe nose and paranasal sinuses diseases; generally concerning the rhinopharyngealtubal district.Restoring mucociliary clearance of the nasal epithelium when altered thus represents a key therapeutic tool against rhinosinus chronic diseases.This study evaluates the clinical efficacy of the inhalation of a natural compound (Narivent® nasal spray) in chronic vasomotor rhinitis., Methods: The study involved 79 patients suffering from chronic vasomotor rhinitis presenting an increased mucociliary clearance time. Patients were randomized into 2 groups: a first group of 49 subjects and a second group of 30 subjects.The first group was treated with a nasal spray (Narivent® nasal spray) (2 sprays per nostril twice a day) for 30 days.The second group was treated with a nasal spray containing isotonic solution in the same way and for the same period of the first group.Nasal Mucociliary transport time was measured in the patients of both groups before treatment, after 15 days of treatment, and at the end of the 30 days treatment., Results: The study shows how one of the treatments carried out determines a major objective reduction of the mucociliary clearance time in the patients under examination, using the method which involves the use of an insoluble coloured tracer (vegetable carbon), bringing the values back within normal range. At the end of the study we objectivated an increase in the rate of mucociliary transport in 97.9% percentage of patients we enrolled., Conclusions: This study shows the effectiveness of treatment with natural extracts with nasal mucosa restoring function in the treatment of chronic vasomotor rhinitis, a nasal inflammatory disease characterized by morphological and functional alteration of the normal nasal mucosa.

Introduction  This study is a systematic review on recent developments about the importance of HMGB1 protein in the pathogenesis of rhino-sinusal inflammatory diseases. We also report data on the use of 18-β-glycyrrhetic acid (GA), which has been shown able to inhibit the pro-inflammatory activities of HMGB1, in young patients affected by allergic rhinitis and complaining of nasal obstruction as main symptom. Objectives  The objective of this study was to review the literature to demonstrate the importance of HMGB1 in the pathogenesis of nasal inflammatory disorders and understand whether the inhibition of this protein may be an efficacious and innovative therapeutic strategy for patients with rhino-sinusal inflammation. Data Synthesis  Authors searched for pertinent articles indexed in PubMed, Scopus, and other health journals between 2004 and 2015. In total, the authors gathered 258 articles: 219 articles through Pubmed and 39 articles from other search engines. The search terms used were as follows: HMGB1 AND "respiratory epithelium," "airway inflammation," "rhinitis," "allergic rhinitis," "rhinosinusitis," "nasal polyposis," "glycyrrhetic acid," "children." Conclusions  Patients with severe symptoms have the highest serum levels and the highest extracellular expression of HMGB1. GA inhibits HMGB1 chemotactic and mitogenic function by a scavenger mechanism on extracellular HMGB1 accumulation stimulated by lipopolysaccharides in vitro. Treatment of allergic rhinitis with GA is not associated with local or systemic side effects in children and adults.

Background Radon-222-enriched hot spring therapy, which is characterized by a safe level of radioactivity, is used for the treatment of rheumatic disorders, and its efficacy has already been studied in several clinical trials. Radon-water inhalation therapy for the treatment of upper and lower airway inflammatory diseases is used in many hot springs centers. However, its application has not been reviewed to date. Methods We systematically searched the PubMed and Scopus databases for clinical trials published in the last 20 years in which objective parameters of upper and lower airway function had been tested before and after radon-enriched inhalation treatment. Results Four prospective studies were found: 1 asthma trial, 1 placebo-controlled chronic rhinosinusitis trial, 1 upper respiratory tract inflammation with nasal obstruction trial, and 1 case-control allergic rhinitis trial. Patients were treated with nasal inhalations of radon-enriched water for 12 to 28 days and were assessed at baseline and after therapy. After 2 weeks of treatment, nasal resistance decreased, flow increased, mucociliary clearance was enhanced, ciliated-to-muciparous cell ratio increased, and %FEV1 increased in asthmatic patients. Conclusion Radon-enriched inhalation therapy improves objective indicators of nasal function in allergic rhinitis and chronic rhinosinusitis, and causes relief of pulmonary obstruction in asthma.

Background and Aim: The aim of our study has been to investigate the perception of aspects related to nasal perforation among experts in Rhinology and ENT surgeons. Our aim was reporting the situations in different Countries to improve the knowledge of colleagues interested in this topic., Methods: A panel of experts prepared a 20-question questionnaire regarding nasal perforations and their surgical repair, that were emailed to all the members of SIR (Società Italiana di Rnologia - Italian Society of Rhinology)., Results: Data obtained from their answers showed that Cottle technique (64%) is the most common technique to perform septoplasty worldwide. 37% of the sample reported an occurrence of nasal septal perforation in less than 1% of patients and 75% attributed this occurrence to the skill of the surgeon, to infections, to drug use and to septal deformity. Trauma, pressure and Wegener's granulomatosis were also mentioned. The most common closure technique is the mucosal flap (75%), followed by the cartilage grafts (11%). Much less common were oral flaps, septal buttons and others. The majority agreed not to suggest septal perforation surgery in minimal (less than 3-4mm) perforations (73.5%), or limiting it to symptomatic patients (43.5%). The contraindications to repair surgery were reported to be: Wegener's granulomatosis, drug abuse, non-symptomatic perforation, its dimension and age of the patient. Septal deviation, atrophic rhinitis, smoke epistaxis and systemic diseases were also claimed. Failure in repair surgery has been observed to occur in less than 30% of cases., Discussion and Conclusions: Given the great difficulty to make random studies about controversial topics and obtain statistically significant data related to that, expert opinion shall be of great value (expert opinion, level of evidence 5)., (Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello.

High-mobility group box 1 (HMGB1) is a nuclear non-histone protein, playing a critical role as a mediator between innate and acquired immunity; when released extracellularly, it coordinates the cellular stress response (under necrosis, bacterial lipopolysaccharide stimulation) and acts as an inflammatory marker and cytokine. The aim of the study was to demonstrate whether HMGB1 is over-expressed in chronic middle-ear pathologies and whether the entity of expression and the localization are correlated with the degree of the inflammatory reaction, thus suggesting that HMGB1 may play a crucial role in chronic inflammatory disorders of the middle ear, as already demonstrated in other airway diseases. We analyzed 30 samples of middle-ear mucosa in patients affected by chronic suppurative otitis media with ear drum perforation with/without cholesteatoma and otosclerosis as control. The distribution of HMGB1 was evaluated as nuclear, cytoplasmic, and/or extracellular staining. The inflammatory cells observed in the biopsies were mostly lymphocytes and plasmacells. A statistically significant difference in inflammation score between otosclerosis and chronic otitis samples ( P < 0.01; Anova test) and between otosclerosis and cholesteatoma samples ( P < 0.05; Anova test) was observed; the HMGB1 positivity was in accordance with the density of the inflammatory infiltrate. HMGB1 is over-expressed in chronic middle-ear pathologies and may play a role in the progression of the inflammatory process from recurrent acute otitis media to chronic suppurative otitis media.

To extend our understanding of previous studies on the pathogenesis and mechanism of high mobility group box 1 (HMGB1) in chronic rhinosinusitis with nasal polyps (CRSwNP), here we show that Sirtuin 6 (Sirt6), one of the Sirtuin family members which are widely studied in aging, DNA repair, metabolism, inflammation and cancer, was expressed in normal nasal mucosa using immunohistochemical staining and Western blot assay. Sirt6 expression levels were decreased in CRSwNP tissue. Sirt6 expression levels were modulated by small interfering RNA transfection in human nasal epithelial cells (HNE). We found that depletion of Sirt6 suppressed the number of human nasal epithelial cell cilia, and dramatically induced HMGB1 translocation from nucleus to cytoplasm in the HNE cells. Glycyrrhizic acid (GA) and glycyrrhetinic acid (GTA) are specific chemical compounds that may be isolated from the licorice plant. GTA has been shown to have anti-inflammatory and anti-allergic activity: it binds selectively to HMGB1 protein released extra-cellularly and inhibits its cytokine activities through a scavenger mechanism on the protein accumulation. In an in vitro study we used the 18-β-stereoisomer of GTA to enhance Sirt6 expression levels, inhibiting through this mechanism the translocation of HMGB1 protein from nucleus and reversing its extracellular accumulation stimulated by lipopolysaccharides. These findings reveal a previously unknown role for nasal mucosa steady-state conditions in the control of Sirt6 activity, and provide evidence for a relationship between HMGB1 and Sirt6 in CRSwNP, and promising benefits of glycyrrhetinic acid for CRSwNP patients.

Obstructive sleep apnoea syndrome (OSAS) is a sleep disorder that leads to metabolic abnormalities and increased cardiovascular risk. This study aimed to define the expression and clinical significance of biomarkers involved in oxidative stress in patients with OSAS. A prospective study was designed to compare outcomes of oxidative stress laboratory tests in three groups of subjects. The study involved the recruitment of three groups of subjects, 10 patients with obstructive sleep apnoea syndrome with AHI > 30; 10 patients suffering from snoring at night with AHI < 15; 10 patients with nasal respiratory impairment with AHI < 5. Patients were subjected to skin prick tests for common aero-allergens, nasal endoscopy, active anterior rhinomanometry, fibrolaryngoscopy and polysomnography; and extra-routine diagnostic tests and procedures; analysis of oxidative and antioxidant (plasma thiol groups) biomarkers in blood and urine samples. No statistical differences in age, sex distribution or body mass index were present between the three groups (p > 0.05). There were significant differences in AHI among the three groups of patients (p < 0.05). No statistical significance was found in the Analysis of Variance (ANOVA) test (p > 0.05) between the levels of biomarkers of oxidative stress in the three populations studied. The results of our study show that the nose can play a role in the pathogenesis of OSAS through the production of biomarkers of oxidative stress., (© Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.)

Unlabelled: The inflammatory diseases of the nose, rhino-pharynx and paranasal sinuses (allergic and non allergic rhinitis, NARES; rhinosinusitis with/without nasal polyposis, adenoidal hypertrophy with/without middle ear involvement) clinically manifest themselves with symptoms and complications severely affecting quality of life and health care expenditure. Intranasal administration of corticosteroids, being fast, simple, and not requiring cooperation, is the preferred way to treat the patients, to optimize their quality of life, at the same time minimizing the risk of exacerbations and complications. Among the different topical steroids available on the market, we performed a comparative analysis in terms of effectiveness and safety between mometasone furoate (MF) and its main competitors. Searching through Pub Med and Google Scholar and using as entries "mometasone furoate", "rhinitis", "sinusitis", "asthma", "polyposis", "otitis media with effusion", and "adenoid hypertrophy" we found 344 articles, 300 of which met the eligibility criteria. Taking into account relevance and date of publication, a sample of 40 articles was considered for the review. MF effectiveness for treatment and/or prophylaxis of nasal symptoms in seasonal and perennial allergic rhinitis has been fully established with a level of evidence Ia. Even though it has not been assessed for MF in particular, topical steroids are the most appropriate treatment in mixed rhinitis and NARES. In acute rhinosinusitis (ARS) evidences support their use as mono-therapy or as adjuvant to antibiotics for reducing the recurrence rate, and decrease the usage of related prescriptions and medical consultations. In chronic rhinosinusitis (CRS) with Nasal polyposis, MF reduces polyps size, nasal congestion, improves quality of life and sense of smell and it is also effective in the treatment of daytime cough. The topical use of MF has great efficacy in the management of adenoidal hypertrophy and otitis media of atopic children. As regards the safety, MF has demonstrated an excellent safety profile: pregnant women can safely use it; no systemic effects on growth velocity and adrenal suppression have been shown; no changes in epithelial thickness or atrophy have been observed after long term administration of the drug., Conclusions: MF has been demonstrated to be effective in the treatment of the inflammatory diseases of the nose and paranasal sinuses; when compared to its competitors it shows a greater symptom control; it is a reliable treatment in the long term thanks not only to its proven efficacy, but also to its safety being on the market since more than 17 years.

Allergic rhinitis is a common nasal disorder with a high impact on quality of life, high social costs in therapies, and a natural development towards asthma. Pharmacological therapy is based on several genres of medications, of which intranasal corticosteroids are currently the most widespread. Thermal water treatment has traditionally been used as adjunctive treatment for chronic rhinitis and sinusitis. The present study was carried out to assess the clinical efficacy of nasal inhalation of radioactive oligomineral water vapours from the Merano hot spring and to compare it with the clinical efficacy of mometasone furoate nasal spray. A comparative prospective study was performed in 90 allergic patients treated at Merano hot springs: a group of 54 subjects treated with radioactive thermal oligomineral water and a control group of 36 subjects treated with mometasone nasal spray. Patients of both groups were assessed before and after treatment by Sino-Nasal Outcome Test questionnaire, active anterior rhinomanometry with flow and resistance monitoring, measurement of mucociliary transport time, and cytological examination of nasal brushing/scraping. The study showed that inhalation treatment with radioactive hydrofluoric thermal water for two weeks produces an objective clinical and cytological improvement in allergic patients, similar to that obtained with mometasone furoate nasal spray.

Background/aims: High mobility group box 1 (HMGB1) is a protein belonging to the class of damage-associated molecular pattern molecules, which activates innate immunity and powerful inflammatory factors. The aim of this review is to show the importance of HMGB1 in the pathogenesis of nasal inflammatory diseases and to suggest that inhibition of HMGB1 may be an innovative therapeutic target., Methods: We used immunohistochemistry to study whether HMGB1 increases in chronic rhinosinusitis with nasal polyps and whether its expression is associated with eosinophils and inflammatory cytokines. Using primary cultures of human nasal epithelial cells, we localised lipopolysaccharide-induced active translocation and release of HMGB1 by immunofluorescence assay and Western blot., Results: Patients with severe symptoms have the highest HMGB1 serum levels. Glycyrrhetic acid inhibits the chemotactic and mitogenic function of HMGB1, binding to the hydrophobic residues that delimit the pockets in box A and B., Conclusions: Chronic inflammatory diseases of the nose and paranasal sinuses are increasingly prevalent and are a financial burden for society. HMGB1 has been shown to play a role in several inflammatory diseases of otolaryngological interest. The inhibition of HMGB1 may be an innovative therapeutic target for patients with chronic upper airway inflammatory diseases having nasal obstruction as a major symptom., (© 2016 S.

Acute rhinosinusitis (ARS) is a very common/disease faced more often by general practitioners than ear, nose and throat specialists, pneumologists or allergologists. In an outpatients setting, upper respiratory tract infection is the third most common cause of a primary care consultation, one third of which is attributable to ARS, diagnosed upon clinical presentation. In some cases however, signs and symptoms do not allow clear differentiation from viral, post-viral or bacterial infection. This compels GPs and family doctors to make a careful choice and first use the best antimicrobial treatment to avoid recurrences or complications and the rise of antibiotic resistance. Amoxicillin, thanks to its narrow spectrum against likely respiratory pathogens, is recommended as first-line therapy to treat acute bacterial rhinosinusitis by several international guidelines, being safe at the same time. Other antibiotics (beta-lactams, macrolides and newer drugs, such as fluoroquinolones) have been evaluated in double-blind studies versus placebo or comparative studies in terms of efficacy, safety and costs. Prulifloxacin, the active metabolite of ulifloxacin, is an oral fluoroquinolone with a broad in vitro activity spectrum against Gram positive and negative bacteria and among fluoroquinolones has the lowest power of inducing resistance. In vitro and in vivo studies have shown its clinical efficacy and pathogen eradication. Ulifloxacin T(1/2) and plasma and tissue concentrations including the nose-paranasal sinuses mucosa allow once daily administration at the dosage of 600 mg. Prulifloxacin shows a high safety profile: it is the fluoroquinolone with the lowest risk of cardiac arrhythmias for prolongation of the QT interval; the CNS penetration is negligible; in women prulifloxacin does not affect the lactobacillary component of the vaginal microbiota, lowering the risk of genito-urinary tract infections. The pharmacokinetic characteristics and safety profile of prulifloxacin make it the antibiotic option with the best potential to achieve clinical cures and bacteriological eradication, well tolerated and safe without specific restriction or posologic changes in the elderly and in patients with co-morbidities in multiple treatment, hence resolving ARS reliably and being simple and easy to administer.

Background: Fencers often complain of progressive difficulty in breathing during matches, which is generally attributed to restricted air, light and heat circulation from wearing a mask. Physiologically, the nasal structure generates airflow resistance that can reach -50% of the total respiratory resistance., Objectives: This study aims to investigate the presence of nasal obstruction in fencers and the relationship with the use of mask., Materials and Methods: An observational study on 40 fencers (18 males, 22 females) was conducted. Fencers perform a usual assault, wearing the mask and standardized physical exercises (running, sprints and obstacles) without the mask. ENT examination with a nasal flexible fiberscope, Anterior Active Rhinomanometry (AAR) and Peak Nasal Inspiratory Flow (PNIF) measurement before and after physical activity with or without the mask was recorded., Results: Before physical exercise, the total nasal airway resistance mean value for AAR was 0.33 ± 0.17 Pa/cm(3)/s at 150 Pa. After a match with the mask, the mean value was 0.28 ± 0.16 Pa/cm(3)/s. After normal physical exercises without mask, the mean value was 0.24 ± 0.15 Pa/cm(3)/s. Using t tests, statistically significant difference between nasal resistance before and after physical activity (P < 0.05) was observed, but no significant difference in nasal resistance between the basal value and that taken after a match wearing the masks (P = 0.1265). PNIF values significantly increase with exercise (P < 0.05)., Conclusions: Our study shows that wearing the mask causes increased breathing impairment in fencers, when compared with similar physical activity without the mask.

Aim: Despite the availability of a number of pharmacological options, relief of allergic rhinitis (AR) symptoms, especially nasal obstruction, is often limited and local and systemic adverse reactions are not infrequent. The main aim of the present pilot study was to provide subjective and objective evidence of the clinical efficacy in reducing symptoms and safety of a medical device-Grip stop DMG (lactoferrin, carboximetil β-glucan, D-panthenol, dipotassiumglycyrrhizinate) in children affected by allergic rhinitis., Methods: A prospective study with a pre- and post-design has been performed consecutively enrolling 50 pediatric both genders patients affected by persistent AR. Patients received 2 puffs into each nostril twice a day over the course of 4 weeks. The severity of AR symptoms was assessed subjectively as measured by a 0 to 5 Visual Analog Scale, and objectively through active anterior rhinomanometry (AAR) and by means of the evaluation of mucociliary transport time (MCTt). Differences in symptoms scores measured before and after the treatment were compared using Paired-Sample Wilcoxon Signed Rank Test. Proportion of participants with adverse effects attributed to the treatment was computed. The relationship between the subjective score and the AAR and MCT measurements was also assessed., Results: All considered symptoms, including nasal congestion, significantly improved after treatment (P<0.001), while only 1 patient suffered from moderate adverse effects., Conclusion: Results confirm efficacy and safety of this device used in the pediatric population. As previously reported in the scientific literature, also in our study, patient's perception of nasal symptoms corresponded with objective testing.

A growing amount of scientific evidence suggests that herbal medicine may be helpful as an adjuvant treatment in rhinosinusitis. Herein, we systematically review and determine the role, efficacy and safety of phytotherapy in the treatment of acute and chronic rhinosinusitis and establish the qualities of herbal drugs as demonstrated by in vitro and in vivo experiments. Eligible studies published in English or German from January 1990 until June 2014 were identified via electronic database searches. Keywords were: sinusitis, phytotherapy, phytomedicine and herbal drugs. Additional studies were obtained through the references of selected articles. Twenty-two articles met inclusion criteria. Overall, the publications indicated that herbal medicines can have mucolytic, antiviral, antimicrobial, anti-inflammatory and secretolytic effects in experimental animals. Phytotherapy has also been found to be efficacious in reducing the symptoms of acute and chronic rhinosinusitis in children and the adult population in vivo, demonstrating a high level of tolerability and safety. Herbal products developed using phytoneering techniques have shown improvements in performance compared with previous formulations. The current literature suggests that phytotherapy is an effective and safe form of ancillary treatment for rhinosinusitis. In particular, herbal drugs made with the technique of phytoneering have proven effective in acute rhinosinusitis.

Aims: We present a multicenter, prospective, open-label study to assess the efficacy and safety of a phytomedicine. The aim of the research was to evaluate the efficacy and safety of 14 days of treatment with Sinupret for acute rhinosinusitis. Sinupret is a herbal preparation used to restore and maintain the physiological function of the membranes in the sinus cavity., Methods: Sixty patients with acute rhinosinusitis based on the EPOS guidelines were enrolled in the study. Thirty patients were treated with Sinupret Forte, while 30 patients were treated with intranasal fluticasone furoate. The criteria for the evaluation of efficacy were the major symptom scores according to the investigator and the Health-Related Quality of Life score. The criteria used to evaluate safety were the number of patients with adverse events, the patients' vital signs, and laboratory safety., Results: All patients considered showed significant improvements in symptoms. Among the patients treated with Sinupret, none had an adverse event, while 3 patients treated with fluticasone furoate had minor adverse events. The patients' vital signs and laboratory values were normal., Conclusions: The results of this study suggest that this phytomedicinal preparation has a significant level of efficacy in acute rhinosinusitis and that treatment is safe., (© 2015 S.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by eosinophil-dominant infiltration in Europe and the United States. However, CRSwNP in Asia has shown different immunopathologic features. High-mobility group protein box 1 (HMGB1) is a DNA-binding protein that has been suggested to be involved in various chronic inflammatory diseases. The objective of this study is to investigate whether HMGB1 is augmented in the Chinese eosinophilic CRSwNP and if non-eosinophilic CRSwNP is associated with interleukin 5 (IL-5), IL-8, and tumor necrosis factor α (TNF-α)., Methods: Nasal polyps specimens were collected from 41 patients with CRSwNP (20 eosinophilic and 21 non-eosinophilic) undergoing functional endoscopic sinus surgery (FESS). Biopsies of uncinate process, and ethmoidal mucosa from 9 non-CRS patients were used as controls by means of immunohistochemistry (IHC) staining, Western blotting, and quantitative reverse-transcription polymerase chain reaction (qRT-PCR)., Results: HMGB1-positive expression was significantly increased in the epithelium and among the large inflammatory cells infiltration in Eos CRSwNP and non-Eos CRSwNP as compared with controls (p < 0.001). The HMGB1 protein and messenger RNA (mRNA) levels of HMGB1, IL-5, IL-8, and TNF-α were significantly higher in eosinophilic CRSwNP than those from controls and non-eosinophilic CRSwNP, but no significant differences in these markers were found between non-eosinophilic CRSwNP and controls. HMGB1 expression levels correlated significantly and positively with IL-5, IL-8, and TNF-α (rs = 0.665, 0.771, and 0.724, respectively; p < 0.001) and slightly with eosinophil infiltration (rs = 0.149; p = 0.012) and the blood eosinophils count (rs = 0.225; p = 0.001) in all samples., Conclusion: Upregulation of HMGB1 could be a significant marker typically in eosinophilic CRSwNP and it may also contribute to the pathogenesis of CRSwNP along with IL-5, IL-8, and TNF-α., (© 2014 ARS-AAOA, LLC.)

Introduction: Innate immunity is the first protection against microorganisms. Nowadays, there is a growing interest in innate immune molecule known as palate, lung, nasal epithelial clone (PLUNC). PLUNC is a specific product of the airways, of approximately 25 kDa, encoded by adjacent genes found within a 300 kb region of chromosome 20; these proteins must be detected predominantly in the upper respiratory tract., Materials and Methods: We performed a case-control study to investigate the presence of this protein in nasal tissue of patients affected by chronic rhinosinusitis. 59 patients were enrolled (44 cases, 15 controls). We have examined the correlation between the presence of pathology and the PLUNC proteins positivity., Results: 100% of controls have a +++ rated PLUNC proteins positivity, while cases have a lower percentage of positivity. We used χ (2) statistical test to analyze the results of the study and there is a difference statistically significant between cases and controls in PLUNC proteins positivity., Conclusions: These observations suggest that, in response to agents or chemical factors, nasal mucosal epithelium will react and produce PLUNC proteins. So PLUNC proteins have a protective function on upper airways mucosa, as we can see by evaluating the high positivity in control group.

Chronic rhinosinusitis with nasal polyps is a common disease with still unclear pathophysiologic mechanisms. The airway epithelial barrier has been shown to be involved in different chronic disorders, including rhinitis, nasal polyposis and asthma. High mobility group box 1 (HMGB1), a primarily nuclear protein, is involved in the induction of airway inflammation in patients with chronic rhinosinusitis, allergy, asthma and COPD. Pathogen-derived lipopolysaccharide is widely used as a trigger for inflammation. However, the molecular dialogue between LPS and HMGB1 in the delayed inflammatory processes remains to be explored, and the regulation of HMGB1 release through LPS from epithelial cells has not been extensively studied in patients with chronic rhinosinusitis and nasal polyps. The objective of the present study was to investigate the relocation of HMGB1 in LPS-induced human nasal epithelial cells in vitro. We obtained epithelial cells of nasal polyps from 10 patients requiring surgery for sinusitis at the ENT Department of the Chinese PLA General Hospital. The primary cultured human nasal epithelial (HNE) cells were stimulated with LPS. The expression and translocation of HMGB1 in intracellular and culture supernatants were determined using Western blot and immunofluorescence assay. HMGB1 protein was released in a time-dependent fashion in culture supernatants: in fact, expression of HMGB1 protein in HNE cells showed no significant changes at 0-24 h after exposure to 100 μg/ml LPS, but increased significantly at 48 and 72 hr. Immunofluorescence analysis revealed the transfer of HMGB1 from nuclei to cytoplasm in response to LPS exposure after 24 hr. These data reveal a hitherto unrecognized association between HMGB1 and LPS in human nasal epithelial cells. LPS can affect HMGB1 translocation and release, suggesting the involvement of HMGB1, through inflammatory mediators, in chronic rhinosinusitis with nasal polyps.

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

Taking into account the mechanisms at the origin of the airways inflammatory pathologies, our attention has been recently addressed to the study of HMGB1, a protein belonging to the group of alarmins. Alarmins are those molecules which in homeostatic conditions carry out specific metabolic and/or structural functions; furthermore, after a direct trauma or an infection, these molecules are released in the extracellular milieu becoming there activators of the innate immunity and powerful inflammatory factors. In a previous research we found in patients affected with chronic rhinosinusitis with/without nasal polyposis (CRSwNP) an increased expression of this protein in the nucleus of nasal mucosa epithelial cells. HMGB1 was overexpressed also as focal subepithelial infiltration and in the inflammatory cells of patients in comparison with controls. These results suggested a possible pathogenetic role of HMGB1 in CRSwNP. The aim of the present study was to investigate if the expression and localization (nuclear, cytoplasmic and extracellular) of the HMGB1 protein-cytokine is somehow related to the severity and complexity of the histological and clinical picture. We noticed values which have around statistical significance between nuclear HMGB1 and eosinophils infiltrate (p=0.0607) and between nuclear HMGB1 and inflammatory infiltrate (P=0.0524). Even more significant was the correlation between extra-cellular HMGB1 expression and the presence of allergic-hyper reactive conditions such as asthma, allergic rhinitis, NSADs intolerance, antibiotic allergy. HMGB1 was significantly more expressed in the nucleus (p=0.0499) and in the intercellular space (p=0.0380) in allergic patients than in non-allergic subjects and as extra-cellular infiltrate in patients with NSADs intolerance (p=0.0022). These results confirm the role of HMGB1 in the pathogenesis of chronic rhinosinusitis with/without nasal polyposis; besides the higher extra-cellular expression in patients with a more severe clinical and inflammatory picture and the presence of associated co-morbidities suggests to seek for new compounds: these compounds, decreasing the extra-cellular release of this alarmin through a scavenger mechanism, could keep under control the inflammatory process without interfering with the nuclear transcriptional messengers.

Chronic rhinosinusitis with nasal polyposis is considered to be a multifactorial disease where different stimuli (mechanical, viral, bacterial, fungal infection, immunological disorders or dysreactivity, environmental pollution), acting on the mucosa of nasal cavities and paranasal sinuses, lead to epithelial damage and mucosal inflammation. Inflammatory cell infiltration (predominantly eosinophils, but also neutrophils, mast cells, macrophages and lymphocytes), cytokine release and sub-epithelial oedema are the histological pictures that are associated, from the clinical point of view, with nasal congestion, secretion and/or post-nasal drip and facial pain/headache. Recently, the importance of the HMG B-1 protein in the pathogenesis of several inflammatory diseases has been demonstrated. This protein is released from necrotic/damaged cells or immune-activated cells, and by acting on specific membrane receptors causes the release of pro-inflammatory mediators, endothelial activation and the survival of inflammatory cells. The objective of the present study was: i) to determine whether HMG B1 is augmented in chronic rhinosinusitis with nasal polyps; ii) if its expression is associated with eosinophils, TNF-α, IL 5 and IL 8 cytokines typically present in chronic inflammation of the nose and paranasal sinuses; iii) to investigate a hypothetical role of this protein in the pathogenesis of nasal polyposis. Nasal polyps tissue from 21 patients affected by CRSwNP and nasal mucosa from 8 controls was collected at the ENT Department of the Chinese PLA General Hospital and underwent immunohistological staining for detection of HMG B1 protein and IL -5, IL -8 and TNF-α inflammatory cytokines. The degree of HMG B1 protein expression was evaluated by dividing the stained sections in 4 portions: 1) nucleus of epithelial cells, 2) cytoplasm of epithelial cells, 3) focal extracellular infiltration, 4) inflammatory cells. HMG B1 was more expressed in the nucleus of epithelial cells of patients compared with controls. In contrast, epithelial cytoplasm HMG B1 staining was significant lower in patients. Sub-epithelial focal infiltration of HMG B1 protein expression was lower in controls, whereas the expression of HMG B1 in the inflammatory cells in patients was significantly increased in comparison with controls. These data, together with the correlation we found between HMG B1 protein expression in different portions and the number of eosinophils infiltrating cells, or IL -5, IL -8 and TNF-α positive cells in patients, suggest that HMG B1 may play a crucial role in the pathogenesis of chronic rhinosinusitis with nasal polyps.

Background: Allergic rhinitis (AR) is a global health problem that has increased rapidly in prevalence over the past few decades. Nasal congestion, which represents a cardinal symptom of AR, appears to be difficult to treat and, especially for pediatric population, therapies that are both well tolerated and effective in relieving nasal congestion are needed. The aim of the present study was to evaluate the safety and clinical effectiveness of the medical device (lactoferrin, carboximetil β-glucan, D-panthenol, dipotassium glycyrrhizinate) in reducing the allergic rhinitis symptoms., Methods: A multicenter prospective study with a pre-post design was performed consecutively enrolling 100 pediatric patients of both genders affected by persistent AR. Patients received 2 puffs into each nostril 2 times a day over the course of 4 weeks. The severity of AR symptoms, as measured by VAS score, was assessed before and after treatment. The main outcomes were improvement in each symptom score and in overall symptom burden (as measured by average symptom scores). Differences in symptoms scores measured before and after treatment were compared using paired-sample Wilcoxon signed rank test. The proportion of participants with adverse effects attributed to the treatment was also computed., Results: All considered symptoms, including nasal congestion, significantly improve after treatment (p<0.001), while only 9 patients suffered adverse effects (itch, burning sensation, dryness)., Conclusion: These results confirm the efficacy and safety of this medical device in pediatric population., (Copyright © 2012 Polish Otorhinolaryngology - Head and Neck Surgery Society.

Aim of the present study was to investigate the prevalence of allergy in patients affected by both organic and/or functional vocal fold disorders. The secondary aim was to assess the correlation between sex and allergy in dysphonic patients. A retrospective chart review was performed on dysphonic patients. A total of 76 patients underwent fiberoptic endoscopy to assess the objective picture. Logistic regression analyses have been conducted to assess the association between sex and the outcome variables. The laryngoscopic examination revealed the presence of poor glottic closure in 32.9%, hyperkinesias in 11.8%, redness in 11.84%, polyps in 5.3%, oedema in 3.95%, vocal fold hypertrophy in 5.3%, nodules in 42.1%, cordectomy in 2.6%. Allergic rhinitis was present in 56.6%, milk intolerance in 13.2%, asthma in 9.2%, atopic dermatitis in 3.9%, drugs intolerance in 11.8%. A total of 76.32% patients presenting with dysphonia were allergic. A statistically significant association was found between female sex and presence of allergy. In conclusion, allergy testing should be performed routinely on female professional voice users. Mild respiratory disorders must be taken into serious consideration in female professional voice users, who may primarily complain of vocal dysfunction rather than upper and lower respiratory diseases.

In spite of the amount of literature demonstrating the relationship between upper and lower airways, both from the anatomical, and pathophysiological point of view, little is known about the epidemiology, diagnosis and treatment of the Rhino-Bronchial Syndrome (RBS). After the publication, in 2003, of a Consensus Report defining the Rhino-Bronchial Syndrome, an interdisciplinary group of experts made up from the Italian ENT Society (SIO) and the Interdisciplinary Scientific Association for the Study of Respiratory Diseases (AIMAR) met again in 2005 in order to study a protocol which would have, as the main tasks, the analysis of RBS signs and symptoms and standardization of the diagnostic approach. A secondary endpoint was to characterize the most effective therapeutic options and to correct the great dyshomogeneity in the therapeutic approaches. With this aim, 9 ENT and Pneumology Centres were selected, based on the ability to multidisciplinary cooperation, availability of useful instrumentation and homogeneous distribution over the entire National territory. Overall, 159 patients were enrolled according to clinical history (major and minor symptoms of upper and lower airways) and inclusion/exclusion criteria. All underwent a two level diagnostic approach. In 116 patients, the diagnosis was confirmed on the basis of I level (rhinopharyngeal endoscopy and basal spirometry, respectively, for upper and lower airways) examination. Allergic and infectious diseases were significantly more frequent (37.9% vs 20.9% and 73.3% vs 46.55, respectively) in patients with a confirmed diagnosis for Rhino-Bronchial Syndrome. Nasal obstruction (93%), rhinorrhoea (75%), cough (96%) and dyspnoea (69%) were the more frequent symptoms. The presence of meatal secretions or polyps were the clinical findings significantly differing at endoscopy in the two groups. After 3 months of treatment, according to "good clinical practice" (inhaled steroids, antibiotics, nasal lavages), 96% of the patients recovered. On the basis of these results, a diagnostic flow-chart is proposed according to which the persistence of some symptoms (cough, dyspnoea, rhinorrhoea and nasal obstruction) should lead the patient to a multidisciplinary and multi-level diagnostic approach by an otorhinolaryngology and a pneumology specialist working together for a definitive diagnosis. The recovery rate of about 94% of patients after 3 months of treatment, stresses the importance of a correct diagnosis.

Five years after publishing the document on 'The clinical and organizational appropriateness of tonsillectomy and adenoidectomy' in 2003, a multidisciplinary group of experts came together again to update this document and to publish a guideline with grading of evidences and recommendations. Major revisions of the previous document were addressed to: (1) the diagnosis and indications for adenotonsillectomy in presence of OSAS in children, (2) the analysis of advantages of new surgical techniques in terms of effectiveness, costs or the risk of postsurgery bleeding and recurrences, and (3) the efficacy of perioperative management in reducing the incidence and duration of post-operative events. In fact, in the last years, a relevant number of evidence became available on the above-mentioned items making the need for a continuing updating of guidelines tangible. As a premise to the guideline, it is stressed how the previous document impact was prominent: the decrease of total number of tonsillectomy in Italy was evident and accompanied by a decrease of variations in the regional rates. Besides the document contributed to strengthen the multidisciplinary collaboration, especially between pediatricians and otorhinolaryngologists, and to divulge the Evidence-Based Medicine culture., (Copyright © 2011 S.
