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.

Objectives Suffocation due to foreign bodies (FB) is a leading cause of death in children aged 0–3 and it is common also in older ages, up to 14 years old. Based on the RPA report the estimated number of incidents per year in children aged 0–14 is in European Union (EU) of approximately 50,000, 10% of which are fatal. The need of an improvement of knowledge led to the development of the pan European study ESFBI (European Survey on Foreign Bodies Injuries) that collected data on FB injuries in the aerodigestive tract in paediatric patients from 19 European Hospitals (Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Finland, Germany, Greece, Italy, Poland, Romania, Slovakia, Slovenia, Spain, Sweden, Swiss, Turkey and United Kingdom). Recognizing that the rapid management is one of the main goals in the presence of such injury the aim of this paper is to confront data coming from 4 ESFBI case series with a Thailand's case series, in order to broaden the knowledge on FBs injuries characteristics, knowing that features like shape, dimension, consistency are fundamental in determine the consequences that might occur. Methods Data coming from the Siriraj Hospital, Thailand from June 2006 to 2010 were collected and compared with 4 case series chosen amongst the ESFBI study cases (Finland, Slovenia, Sweden and Turkey). Results 172 cases were collected from the Siriraj Hospital in Bangkok, Thailand. The chosen ESFBI members were Finland, Sweden, Slovenia and Turkey, with a sample numerosity respectively of 307, 235, 104 and 196 cases. All countries showed a male prevalence higher than the female one, and injuries occurred most frequently in children younger than 3 years old. The most frequent retrieval location was the digestive system (oesophagus) in Thailand data (97 cases, 56.40% of cases), whilst European cases involved more frequently the nose in Slovenia (58.65%), Finland (37.79% of cases) and Sweden (54.47%). In Turkey's case series, the highest prevalence of cases interested the airways. In Thailand and Finland case series, the main FB's type were represented by bones (respectively 66 case, 38.37% and 48 cases, 15.64%), whilst pearl, ball and marble were the most frequent FB both in Slovenia (16, 15.38%) and Sweden (83, 35.32%). Turkey case series had nuts, seeds and grain as most prevalent FB (126, 64.29%). Conclusions The nature of foreign bodies varies from country to country and is dependent on diverse cultural, social, religious and economic factors that include parental attitudes, eating habits, availability and types of potentially threatening objects, and prevention strategies. The need to study in more depth specific characteristics of foreign bodies associated with increased hazard, such as nature, size, shape, hardness or firmness, lubricity, pliability and elasticity, in order to better identify risky foods and to describe more precisely the pathogenetic pathway is therefore a necessity.

The aim of the present study is to characterize the risk of complications and prolonged hospitalization due to stationery items according to age and gender of patients, FB characteristics and foreign body (FB) location, circumstances of the accident, as emerging from the ESFBI study.A retrospective study in major hospitals of 19 European countries was realized on children aged 0-14 having inhaled/aspired or ingested a stationery item. In the years 2000-2003 a total of 2094 FB injuries occurred in children aged 0-14 years. The characteristics of the child, the FB consistency and the occurrence of complications were analyzed.Among FB injuries, 62 (3%) were due to a stationery item: 32 were due to objects insertion in the ears while 30 occurred in the upper and lower respiratory tract. Objects most frequently involved are parts of pens in children younger than 3 years and eraser in older. 39% of children needed hospitalization. The most documented complication was inflammation of external ear. Almost 24% of injuries happened under adults' supervision.Injuries are events that in many cases can be prevented with appropriate strategies. Passive environmental strategies, including product modification by manufacturers, are the most effective. Our study testifies that stationary is involved in a non negligible percentage of FB injuries. This results confirm the fact that when passive preventive strategies are not practical, active strategies that promote behaviour change are necessary and information about this issue should be included in all visits to family pediatricians.

SUMMARY Obstructive sleep apnoea syndrome is a disease characterized by a collapse of the pharyngeal airway resulting in repeated episodes of airflow cessation, oxygen desaturation, and sleep disruption. It is a common disorder affecting at least 2-4% of the adult population. The role of nasal resistance in the pathogenesis of sleep disordered breathing and sleep apnoea has not been completely clarified. Aim of the present study was to establish whether nasal resistance and nasal volumes, measured by means of Active Anterior Rhinomanometry and Acoustic Rhinometry together with Muco-Ciliary Transport time play a positive predictive role in the evaluation of Obstructive sleep apnoea syndrome patients before running a nocturnal polysomnographic recording. A retrospective study was performed analysing 223 patients referred for suspected Obstructive sleep apnoea syndrome. All patients were submitted to complete otorhinolaryngological evaluation and underwent nocturnal polysomnography. On the basis of polysomnographic data analysis, the apnoea-hypopnoea index and snoring index, patients were classified into two groups: Group 1 (110/223 patients) with a diagnosis of mild-moderate Obstructive sleep apnoea syndrome (apnoea-hypopnoea index < 30) and Group 2 (113/223 patients) affected by snoring without associated hypoxaemia/hypercapnia. A control group of 76 subjects, not complaining of sleep disorders and free from nasal symptoms was also selected. The results showed, in all the snoring and Obstructive sleep apnoea syndrome patients, total nasal resistance and increased Muco-Ciliary Transport time compared to standard values. Furthermore, the apnoea-hypopnoea index was significantly higher in patients with higher nasal resistence and significantly different between the groups. These results allow us to propose the simultaneous evaluation of nasal functions by Active Anterior Rhinomanometry, Acoustic Rhinometry, and Muco-Ciliary Transport time in the selection of patients undergoing polysomnography.

Sublingual immunotherapy with monomeric allergoid, given according to the standard schedule, was reported to be effective and safe in many clinical trials. However, a long period of time may elapse before achievement of a clinical benefit. This study was thus performed using two different shortened (4-day) induction (= up-dosing) schedules, which allowed a rapid achievement of the maintenance dosage. Overall, 86 patients suffering from rhinitis and oculorhinitis have been recruited, none of whom had received immunotherapy before. The study design was prospective, randomized, with three parallel groups receiving, according to a randomization list, one of the three induction (two up-dosing one no-up-dosing) phase schedules under study. A fourth group of patients served as controls, and did not receive any sublingual immunotherapy but only rescue medications if and when necessary. All patients were evaluated to assess their baseline conditions, and thereafter at 3 and 6 months. The evaluation parameters were: Visual Analogue Scale, symptom-medication scores, nasal provocation test. All three induction schedules under study were well accepted by the patients, with very few adverse reactions. The clinical efficacy, evaluated with Visual Analogue Scale (p < 0.001), symptom-medication scores (p < 0.02) and nasal provocation tests (p < 0.01), was found to be significant in all three sublingual immunotherapy-treated groups of 64 (n86) patients, but was not significant in controls 22 (n86). According to the Authors, with this simplified schedule process, sublingual immunotherapy is a therapeutic option that is becoming increasingly well-accepted not only by allergy specialists but also by patients.

The aim of our study was to evaluate the efficacy of 30 days treatment with glucan solution nasal spray vs. saline in the treatment of signs and symptoms of chronic rhinosinusitis.100 patients affected by chronic rhinosinusitis were enrolled. At the beginning and at the end of the study were evaluated: nasal congestion, headache, rhinorrea, facial pain, rhinopharyngeal exudate, inferior turbinate hypertrophy; a complete instrumental analysis of nasal functions by Active Anterior Rhinomanometry, nasal Muco-Ciliary Transport time and scraping of nasal mucosa was also performed. The patients were randomized 1:1 for receiving intranasal saline or intranasal glucan solution spray. Treatment was administered as follows: 2 puffs/nostril 3 times a day for 30 days.The patients in therapy with the glucan solution showed a significant improvement concerning rhinorrea facial pain, intensity of headache, inferior turbinate hypertrophy, rhinopharyngeal exudates, inspiratory/expiratory nasal resistences, Muco-ciliary transport time, normalization of nasal mucosas and rhinocytogram; saline lavage didn't show this effects. Both treatment improved rhinorrea, instead both treatment didn't affect nasal congestion.According to the results of our multicentric double blind randomized study, we suggest the use of glucan solution nasal spray as an efficacious therapeutic tool in the management of nasal symptoms in patients affected by chronic rhinosinusitis.

to evaluate the relationships between headache and nasal obstruction or nasal allergy on a group of Italian school children.One hundred twenty-six children suffering from headache, were enrolled in the study. All patients underwent an accurate clinical history, a complete ENT objective examination, an Anterior Active Rhinomanometry, an analysis of nasal mucociliary transport time and a skin test on the inner forearm.Nasal resistances were increased in 101 out of 105 of children (96.2%) affected by severe headache (group A) and in 5 out of 21 (23.8%) of those affected by sporadic headache (P0.0001), for an odds ratio of 80.0 (95% CI, 19-343). The analysis of mucociliary transport time offered results comparable with those of the Anterior Active Rhinomanometry.Dysfunctions of nasal physiology, as stated by the alteration of nasal resistances and nasal mucociliary transport, seem to be able to affect the development and the characteristics of headaches; specifically we found that children with an altered nasal physiology have more severe and more frequent attacks of headache.

To evaluate the relationship between airbag-induced noise and individual metabolic risk factors in determining persistent hypoacusia in drivers after road accidents.We selected 22 patients previously involved in a car accident with deployment of airbags. Patients underwent general and audiological clinical history, tonal audiometric examination, vocal audiometric examination, impedance meter examination and blood tests.We divided patients, according to audiometric data, into 2 groups: group A with no residual otological disturbances (6 subjects) and group B with persistent hypoacusia (16 subjects). Blood parameters were into physiological levels in all group A patients; on the contrary 12 (subgroup B1) out of 16 group B patients had altered blood levels of glucose, urea and cholesterol, with mean values of 155.8 +/- 38.6 mg/dl, 48.2 +/- 8.3 mg/dl and 250.8 +/- 28.1 mg/dl, respectively, revealing statistically significant differences in these parameters when compared with the other 4 hypoacusic cases (Sub-group B2) and with the normal subjects (Group A) (p0.01 for glucose, p0.05 for urea and p0.001 for cholesterol).Our findings confirm the transitory otological damage due to airbag deployment: the intensity of the acoustic wave hitting the ear after airbag deployment is responsible for a temporary rise in the acoustic threshold but the persistence of an auditory deficit can be due to co-factors able to interfere with the acute acoustic trauma recovery processes through a metabolic, angiopathic, neuropathic or unknown mechanism. Moreover, also the age of the patients could affect in a significant way the recovery from the acoustic trauma.

Polyfunctional aziridine (PFA) hardener is increasingly used in water-based paints and inks as a replacement for organic solvents. Allergic contact dermatitis, contact urticaria, respiratory allergy in occupationally exposed patients with hypersensitivity to PFA are reported.The aim was to study a population of adhesive tape printers for occupational respiratory and skin sensitisation to PFA hardener. Also 2 cases of occupational asthma in workers exposed to PFA in tanneries are reported.A standard series prick and patch tests was carried out on 15 workers with skin symptoms out of 36 adhesive tape printers exposed to PFA. Prick tests with a 1% PFA water solution and patch tests with a dilution series (0.1-0.32-0.5-1%) of PFA in petrolatum were performed. Lung and nasal provocation tests with PFA hardener were also carried out on 4 subjects with skin and respiratory symptoms.Skin sensitivity to PFA prick tests was demonstrated in 8.3% of the exposed population; 22.2% of the exposed workers suffered from allergic contact dermatitis due to PFA with positive patch tests for this compound. One case of occupational rhinitis due to PFA was diagnosed.PFA is a strong sensitizer and the use of gloves and protective clothing appears to be insufficient to prevent occupational allergic diseases. Elimination of PFA from production processes is desirable.

Allergic rhinitis is classically defined as an IgE-mediated inflammation of nasal mucosa, characterised by nasal obstruction, rhinorrhea, sneezing and nasal itching. It is certainly a high-prevalence disease and an important social and medical problem in many industrialised Countries, affecting about 20% of the general population; moreover, it is diagnosed with increasing frequency, both in adults and children in many developing countries. In view of the high medical and social costs, a correct diagnostic approach to allergic rhinitis is a fundamental need for the otorhinolaryngologist, also considering the severe complications (asthma, rhinosinusitis, rhino-otitis, rhinosinusal polyposis) which could develop if this disease is not recognised and adequately treated in its early phases. In order to evaluate not only the present epidemiological characteristics of allergic rhinitis in Italy but also the most commonly used diagnostic and therapeutic approaches in the management of this disease, 145 Italian otorhinolaringologists were selected to take part in the investigation. Each was invited to complete a questionnaire, divided into 8 different sections, to be answered according to their daily clinical practice. The significance of the results has been compared with those of the international samples comprised in the ARIA Document and in the epidemiologic survey of the Standing Committee on Rhinology and Allergy of the International Federation of Otorhinolaryngological Societies. A critical analysis of these data leads to some interesting epidemiological and therapeutic considerations.

The aim of the study is to analyze a new method for the elaboration of endoscopic images of the nasal cavity called "videocapture" and to compare the data from this technique with the ones obtained with anterior active rhinomanometry. Videocapture is based on a software program able to process endoscopic images, to file them and to measure perimeter and area of the structures inside the images recorded. We enrolled 27 patients with inferior turbinate hypertrophy and we performed, before and after nasal decongestion test, anterior active rhinomanometry, acoustic rhinometry, videocapture to compare the results obtained with these different techniques. The results we got confirm in a statistically significant way, the reliability of videocapture and its easy way of application.

Purpose of this study was to correlate results from a survey on otitis media and the State-Trait Anxiety Inventory test. This survey investigated prevalence of otitis media (OM) in our territory, influence on development of language and personality and social costs. State-Trait Anxiety Inventory is a suitable test to differentiate state anxiety caused by a specific event [in this case, otitis media with effusion (OME)] from a trait anxiety (anxious personality) in parents and caregivers. The otitis media study was conducted, retrospectively, in two primary public schools in Colle Val D'Elsa (Siena) on 252 children (6-11 years old). The State-Trait Anxiety Inventory test had been administered to the parents or caregivers of 20 paediatric outpatients (4-12 years, mean 6.8) at the ENT Department of Siena University. The results of the OM survey showed a correlation between OM and difficulties in speech and reading, delayed answering and limited vocabulary. All these problems improved as children grew up. On the other hand, psycho-social development appeared to be more problematic even in the 4th and 5th class, mostly due to persistent attention disturbances. In the State-Trait Anxiety Inventory test, 50% of parents or caregivers had a high state-anxiety score and so were mostly concerned with health status of the children. The State-Trait Anxiety Inventory results indicated that 50% of parents or caregivers had a high trait-anxiety score and thus had an anxious personality. These findings could be helpful in understanding the real severity of symptoms. The two proposed tests could provide complementary data to evaluate children with OME: the OM survey can be used as a screening test to detect children with non-symptomatic OME, to establish whether delayed language development may be associated with OME, to predict prognosis and children's quality of life as well as social costs of OME; the State-Trait Anxiety Inventory test can be used to reveal a state or a trait anxiety in parents and caregivers in order to better understand their point of view. Parents' and caregivers' personality has a marked influence on the impact of OME on the children's quality of life. Quality of life in children with otitis media with effusion is one of the most important parameters to be taken into consideration on account of the possible correlation with problems in development.

Even if foreign body (FB) insertion in the external auditory canal (EAC) is not an uncommon event, the literature based on large series is scarce. In the present study, ear FB cases observed at the Children's Hospital Gutierrez in Buenos Aires over five years of otorhinolaryngology (ORL) activity are presented, and the main findings are compared with data coming from other well-known published case series. Three hundred ninety-two injury cases were observed. Eighty percent of them occurred while the child was playing; in 328 cases (83.7%), adults were present. The retrieved FB included food items and objects usually available at home, such as pins, while fragments of toys were found in only 2 cases. These findings testify to the efficacy of regulations imposing manufacturing quality standards on toys; on the other hand, parents seem to be unaware of the risk imposed by FB insertion, since injuries usually happen under adult supervision while children are manipulating objects not adapted for their age.

Amoxicillin/clavulanate in chronic rhinosinusitis: tissue and serum distribution.The aim of the present study is to determine the concentrations of coamoxiclav in the sinusal mucosa of patients undergoing surgery for chronic sinusitis in comparison to serum levels after single oral administration.24 patients affected by chronic sinusitis, undergoing sinus surgery, were divided into three groups receiving an oral dose of 1 g of coamoxiclav (875 mg amoxicillin, 125 g of clavulanic acid, 7:1 ratio) at 2 h (first group), 4 h (second group) and 6 h (third group) before surgery. The mean concentration of amoxicillin and clavulanic acid were determined biologically in serum and in tissues.The highest concentrations of coamoxiclav both in serum and tissues were observed in the group which received the antibiotic 2 hours before surgery. However the tissue levels of both amoxicillin and clavulanic acid in the time period within 2-6 h after administration were higher than the Minimum Inhibitory Concentration (MIC) for the most frequent causative pathogens of sinus bacterial infections.Since penicillins need to maintain concentrations above the MIC for at least 40 to 60% of the interval time between administrations to be potentially effective, the Authors concluded that since both amoxicillin and clavulanic acid spread well in the ENT tissues, 1 g twice a day of the combination seems to be clinically effective even in patients suffering from acute episodes of chronic rhinosinusitis.

The present work aimed at evaluating the efficacy and tolerance of an alternative schedule of local nasal immunotherapy for the treatment of mite dust allergic rhinitis. The authors suggest the nasal administration of the maximum tolerated dosage chosen on the basis of nasal provocation test threshold, comparing allergen extracts in micronized powder and watery solution. Forty-five patients (25 men and 20 women), aged 18 to 66 years, affected by allergic rhinitis to Dermatophagoides (Dpt) were selected and treated either by local immunotherapy in watery solution (15) or in powder form (15) or by parenteral specific hyposensitizing treatment (15). Before and one year after the beginning of the study, the clinical diaries and the total and specific IgE variation were evaluated. The monthly symptoms and drugs use are comparable among the three treatment groups. No significant difference was found, with the exception of local symptomatology, which improved more in patients undergoing local immunotherapy (p0.05); and oral antihistamines use, which was lower in patients treated with the watery solution (p0.05). Thus, local simplified hyposensitizing treatment is able to combine the absence of symptomatological worsening with the decrease of both local and systemic drugs use. The advantages of the LNIT protocol proposed herein are as follows: simplified schedule for self-administration; improved patient compliance; reduction of local side effects; clinical efficacy comparable with subcutaneous specific immunotherapy.
