Analysis of tinnitus severity and associated risk factors in patients with chronic otitis media: data from the multinational collaborative Chronic Otitis Media Questionnaire-12 study.

BACKGROUND: Subjective tinnitus is a common symptom, and there is often an underlying otological cause. This study investigated the degree of tinnitus-related annoyance in patients with chronic otitis media and analysed whether associations with tinnitus severity exist. METHOD: The multinational collaborative Chronic Otitis Media Questionnaire-12 study collected prospective data on 478 adult patients suffering from chronic otitis media across 9 otology referral centres in 8 countries. Based on this dataset, we investigated tinnitus severity using participant responses to item 7 of a native version of the Chronic Otitis Media Questionnaire-12. RESULTS: With respect to tinnitus severity, 23.8 per cent, 17.4 per cent, 15.5 per cent, and 43.4 per cent of participants reported no, minor, moderate, and major inconvenience or greater, respectively. The absence of ear discharge, absence of cholesteatoma, and poorer disease-specific health-related quality-of-life were associated with increased tinnitus severity in patients with chronic otitis media, whereas age, hearing disability and geographical region showed no association. CONCLUSION: This analysis provided novel insight into potential risk factors for tinnitus in patients with chronic otitis media.

Author's reply to the Letter to the Editor "Therapeutic strategies in the treatment of Menière's disease: the Italian experience".

There is still controversy on the role of hyperinsulinemia and endogenous antisecretory factor (EAF) in Meniere's disease. In the literature, there is no mention on glucose uptake or specially processed cereals (SPC). Nevertheless, the role of EAF and its inhibition by SPC should be taken into account in future research. In case of patients not responding to medical treatment and dietary changes, intratympanic (IT) treatment has been suggested. In Italy, generalists consider IT steroids as the first-line treatment, while neurotologists suggest IT gentamicin. We agree with the authors that low-dose IT gentamicin has a high chance to treat vertigo with minimal risks for hearing; however, a recent randomized, double-blind, comparative trial has not proven the superiority of gentamicin to IT steroids suggesting the choice "should be made based on clinical knowledge and patient circumstances". IT steroids have the advantage to preserve both cochlear and vestibular function, while IT gentamicin has an ablative effect especially on the vestibular function.

Ocular and cervical vestibular-evoked myogenic potentials in idiopathic sudden sensorineural hearing loss (ISSHL) without vertigo: VEMPs in ISSHL.

PURPOSE: Idiopathic sudden sensorineural hearing loss (ISSHL) is a hearing impairment greater than 30 dB at three consecutive frequencies developing in less than 3 days. The aim of this study was to evaluate VEMPs and caloric testing in patients affected by ISSHL without vertigo. METHODS: We retrospectively evaluated 35 subjects affected by ISSHL. The audio-vestibular investigation consisted of pure-tone and speech audiometry, impedance, bithermal caloric testing, oVEMPs and cVEMPs. RESULTS: VEMPS were abnormal in 21 patients (60%): cVEMPs in 12 (34.2%) and oVEMPs in 19 (54.2%). 10 patients (28.5%) presented with both c-and oVEMPs altered. Subjects without vestibular involvement showed a significant lower PTA in the affected ear both at admission and at discharge. Recovery rate was significantly higher in group without vestibular involvement. CONCLUSION: The evaluation of the vestibular system can be useful for predicting the auditory recovery in patients without vertigo also.

Long-Term Therapy with Corticosteroids in Nasal Polyposis: A Bone Metabolism Assessment.

Chronic rhinosinusitis associated with nasal polyposis (RSCwNP) affects 4% of the general population. As chronic condition, it requires chronic pharmacological treatment, whereas the surgical approach becomes necessary in obstructive and/or complicated cases. Intranasal and systemic corticosteroids (CS) represent the "Gold Standard" treatment for RSCwNP. The present study aimed to evaluate the side effects of prednisone in a group of patients with RSCwNP treated with long-term CS. In particular, attention was focused on bone disorders (osteopenia and osteoporosis) and prospective fracture risk increase. Forty patients (26 females, mean age 55.70 ± 14.03 years) affected by RSCwNP have been enrolled. Control group included 40 healthy subjects (17 females, mean age 56.37 ± 13.03 years). Nasal endoscopy, skin prick tests, nasal cytology, and bone densitometry were evaluated in all subjects. The likelihood of impaired bone metabolism (osteopenia or osteoporosis) was superimposable in both groups. Within RSCwNP group, no parameter was statistically significant in predicting a metabolism alteration.

Internal nasal dilatator (Nas-Air®) in patients who snore.

Snoring is a very common human habit, and for this reason it is considered more a social nuisance that a disease symptom. The nasal valve area has the minimal cross-sectional area of the upper airways. A problem at this level may easily induce impaired breathing and consequently snoring, therefore nasal dilation might significantly improve this complaint. Nas-Air® is a new internal nasal dilator which was tested on 41 outpatients who snore. Snoring duration, assessed by smartphone, visual analogue scale for the perception of sleep quality were measured before and during Nas-Air® use. A significant reduction of snoring time and an improvement of sleep quality were achieved during Nas-Air® wearing. In conclusion, the present study demonstrates that Nas-Air® is an internal nasal dilator able to reduce snoring time and improve sleep quality.

Treatment of cholesteatoma with intact ossicular chain: anatomic and functional results.

SUMMARY: In case of cholesteatoma with intact ossicular chain, the primary aims of surgery are complete removal of the cholesteatoma matrix and reconstruction of a dry and safe middle ear; if possible, ossicular chain continuity and therefore the preoperative hearing must be preserved. The aim of this retrospective study is to present the experience of the U.O.C. Otorinolaringoiatria Universitaria of University of Bari "Aldo Moro" in treatment of intact ossicular chain cholesteatoma with Bondy modified radical mastoidectomy (BMRM) and canal wall up tympanoplasty (CWUT). The study group was composed of 65 subjects affected by cholesteatoma with intact ossicular chain. Mean age was 40.7 years (range 6-79), with 42 males and 23 females. 30 patients were treated by a BMRM and 35 by CWUT, in 22 cases without mastoidectomy and in 13 cases with mastoidectomy. Mean follow-up was 24.25 months. In the BMRM group, no cases of residual cholesteatoma located in the middle ear space were detected; at follow-up, 1 patient developed a retraction pocket (3.33%), 1 patient showed a small epidermal cysts of the tympanic membrane (3.33%) and 3 patients (10%) experienced otorrhoea. In CWUT, residual cholesteatoma was detected in 2 cases (5.7%); at follow-up, 3 patients presented recurrent cholesteatoma (8.57%; 2, 6 and 8 years after surgery), 3 cases a retraction pocket (8.57%) and one case otorrhoea (2.86%). Statistical analysis showed a significant higher number of residual cholesteatoma in CWUT (p 0.005) and differences in terms of long-term complications. No significant changes in hearing occurred post-operatively or at 1 year follow-up in either group. The current trend in our centre is to perform BMRM when indicated and CWUT preferably without mastoidectomy in case of mesotympanic cholesteatoma with normal OC.

Idiopathic sudden sensorineural hearing loss and ménière syndrome: The role of cerebral venous drainage.

OBJECTIVES: To evaluate the influence of cerebral venous drainage on the pathogenesis of idiopathic sudden sensorineural hearing loss (ISSHL) and Ménière syndrome (MD). DESIGN: Observational, prospective, cohort study. SETTING: ENT and Cardiology Departments (University of Bari, Policlinico Hospital, Bari, Italy). PARTICIPANTS: We enrolled 59 consecutive patients (32 males, mean age 53.05 + 15.37 years): 40 ISSHL and 19 MD. MAIN OUTCOME MEASURE: All patients underwent physical examination, biochemical evaluation (glycemic and lipid profile, viral serology, C reactive protein, etc), audiometric (tonal, vocal, vestibular evoked myogenic potentials and auditory brainstem response test) and impedentiometric examination. The pure tone average (PTA) was calculated for the following frequencies: 250, 500, 1000, 2000, 3000, 4000, 8000. An echo-color Doppler evaluation of the venous cerebral veins, internal jugular (IJV) and vertebral veins (VV) at supine and 90° position was performed. RESULTS: No morphological alterations were found both in patients and controls. There were no signs of stenosis, blocked flow, membranes, etc. We found lower minimum, mean and maximum velocities in distal IJVs (P = .019; P = .013; P = .022; respectively) and left VVs (P = .027; P = .008; P = .001; respectively) in supine (0°) position in both MD and ISSHL patients as compared to controls. The same was for orthostatic position (90°). We found negative correlations between the velocities in extracranial veins and PTA values: therefore, the worst the audiometric performance of the subjects, the lower the velocities in the venous cerebral drainage. CONCLUSIONS: Idiopathic sudden sensorineural hearing loss and Ménière syndrome patients showed altered venous flow in IJVs and VVs as compared to controls, independently from posture. This different behavior of venous tone control can influence the ear performance and may have a role in the pathogenesis of both diseases.

Allergic and nonallergic rhinitis and skin sensitization to metals: is there a link?

SUMMARY: Background. Chromium, Cobalt and Nickel are responsible for contact dermatitis, that is largely prevalent in the general population. They can act also as irritants in the upper and lower respiratory airways. Also rhinitis (allergic and nonallergic) is a high prevalence disorder. Both diseases could share some common inflammatory mechanisms, but the clinical association between skin sensitization to metals and rhinitis was never studied. Objective. We assessed the presence of skin sensitization to metals in subjects with rhinitis. Methods. Patients suffering from rhinitis underwent a standard diagnostic procedure, including skin testing, nasal endoscopy and nasal cytology. Control healthy subjects were also included. None of the patients had skin diseases. All subjects underwent patch test with Chromium, Cobalt and Nickel. Results. None of the 26 controls had positive skin prick test or nasal cytology. The 82 rhinitis patients were subdivided into allergic (group A = 27), nonallergic (group B = 31) and overlapping (group C = 24). The prevalence of positive patch test to metals was 26% in group A, 45% in group B, 42% in group C and 31% in controls. The percentage of patch-positive subjects was significantly different between Group A and B (p = 0.0045; OR: 0.43), Group A and C (p = 0.0186; OR: 0.49), and Group B and controls (p = 0.0360; OR: 1.85). There was a significant difference between groups A + controls and B + C. Conclusion. Even in the absence of skin diseases, the prevalence of sensitization to metals (patch test) is greater in nonallergic and overlapping rhinitis, as compared to allergic rhinitis and controls.

Non-surgical management of chronic rhinosinusitis with nasal polyps based on clinical-cytological grading: a precision medicine-based approach.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common inflammatory disorder that strongly impacts patients' quality of life. CRSwNP is still a challenge for ENT specialists due to its unknown pathogenesis, difficult control and frequent relapse. We tested the hypothesis that a new standardised therapeutic approach based on individual clinical-cytological grading (CCG), may improve control of the disease and prevent the needing for surgery. We analysed 204 patients suffering from bilateral CRSwNP, 145 patients of whom regularly assumed therapy, respecting the planned check-up, and were considered cases; 59 patients were not assuming therapy as indicated and were considered as controls. After five years of standardised treatment, 15 of 145 (10.5%) improved endoscopic staging, 61 of 145 (42%) did not change their endoscopic staging, and 69 of 145 (47.5%) were worse. In the control group, 49 of 59 (83%) were worse by at least two stages (p < 0.05). Patients and controls were stratified basing on clinical and cytological grading as mild, moderate and severe. After patient stratification, in the mild group (n = 27) 92% patients had a constant trend, with no worsening and no need for surgery over a 5-year period, whereas in the mild CCG control group 1 of 59 (1.6%) required surgery (p < 0.05). In moderate GCC (n = 83), 44% of patients did not modify or improve endoscopic staging and 3.6% needed surgery, compared to 13.6% of controls with moderate GCC (p < 0.05). In severe CCG (n = 35), even though no patients achieved significant amelioration of endoscopic grading, 40% of patients were considered as "clinically controlled" and 5.7% of patients underwent surgery, but the percentage was significantly higher (49%) in the control group significant (p = 0.0000). Finally, statistical analyses revealed a clear trend that polyp size increased at a faster rate in the control group than in the treatment group and for each subgroup (low, moderate and severe). The present study suggests a new approach in the management of CRS according to clinical cytological grading that allows defining the grade of CRSwNP severity and to adapt the intensity of treatment. This approach limited the use of systemic corticosteroids to only moderate-severe CRSwNP with a low corticosteroid dosage in comparison with those previously suggested. Our protocol seems to improve the adherence by patients, control of disease and the need for surgery in the long-term.

Adjuvant treatment with a symbiotic in patients with inflammatory non-allergic rhinitis.

Inflammatory non-allergic rhinitis (INAR) is characterized by the presence of an inflammatory infiltrate and a non-IgE-mediated pathogenesis. This retrospective, controlled, multicentre study investigated whether a symbiotic, containing Lactobacillus acidophilus NCFM, Bifidobacterium lactis, and fructo-oligosaccharides (Pollagen®, Allergy Therapeutics, Italy), prescribed as adjunctive therapy to a standard pharmacological treatment, was able to reduce symptom severity, endoscopic features, and nasal cytology in 93 patients (49 males and 44 females, mean age 36.3±7.1 years) with INAR. The patients were treated with nasal corticosteroid, oral antihistamine, and isotonic saline. At randomization, 52 patients were treated also with symbiotic as adjunctive therapy, whereas the remaining 41 patients served as controls. Treatment lasted for 4 weeks. Patients were visited at baseline, after treatment, and after 4-week follow-up. Adjunctive symbiotic treatment significantly reduced the percentages of patients with symptoms and endoscopic signs, and diminished inflammatory cells. In conclusion, the present study demonstrates that a symbiotic was able, as adjuvant treatment, to significantly improve symptoms, endoscopic feature, and cytology in patients with INAR, and its effect may be long lasting.

Standardization procedure for the nasal nitric oxide measurement method using Niox MINO® and the tidal-breathing technique with velum-closure.

Nitric oxide (NO) is a molecule that performs many functions in the human body. The entire respiratory tract can produce NO, but the highest production occurs in the upper respiratory tract, in the paranasal sinuses in particular. The aim of the present study was to assess a new nasal NO (nNO) measurement method using the Niox MINO Nasal® device (Aerocrine AB, Solna, Sweden) and a special procedure, in order to compare the nNO values obtained in 32 healthy subjects with the values found in the international literature. The measured normal nNO values were equal to 426.76±143.27 ppb, with a 95% confidence interval [160.22-733.30]. Males had an average nNO value equal to 446.76±133.63 [178.64 – 714.02], whereas in females the average value was 403.80±154.90 [94.00-713.60]. This study allows us to confirm that we have been able to establish the normal range of nitric oxide quantity produced in the nasal/sinus cavities of healthy individuals using the Niox MINO Nasal® device and tidal-breathing with velum-closure manoeuvre.

Ancillary therapy of intranasal T-LysYal® for patients with allergic, non-allergic, and mixed rhinitis.

Allergic rhinitis (AR) is caused by an IgE-mediated inflammatory reaction. Non-allergic rhinitis (NAR) is characterized by a non-IgE-mediated pathogenesis. Frequently, patients have the two disorders associated: such as mixed rhinitis (MR). Hyaluronic acid (HA) is a fundamental component of the human connective tissue. HA may exert anti-inflammatory and immune-modulating activities. Recently, an intranasal HA formulation was proposed: a supramolecular system containing lysine hyaluronate, thymine and sodium chloride (T-LysYal®). This randomized study investigated whether intranasal T-LysYal® (rinoLysYal®, Farmigea, Italy) was able to reduce symptom severity, endoscopic features, and nasal cytology in 89 patients (48 males and 41 females, mean age 36.3±7.1 years) with AR, NAR, and MR. Patients were treated with intranasal T-LysYal® or isotonic saline solution as adjunctive therapy to nasal corticosteroid and oral antihistamine for 4 weeks. Patients were visited at baseline, after treatment and after 4-week follow-up. Intranasal T-LysYal® treatment significantly reduced the quote of patients with symptoms, endoscopic features, and inflammatory cells. In conclusion, the present study demonstrates that intranasal T-LysYal® is able, as ancillary therapy, to significantly improve patients with AR, NAR, and MR, and its effect is long lasting.

Intranasal T-LysYal® as adjunctive therapy for patients after functional endoscopic sinus surgery.

Functional Endoscopic Sinus Surgery (FESS) is a common day surgery technique for upper airway disorders. Hyaluronic acid (HA) is a fundamental component of the human connective tissue. HA may exert reparative, anti-inflammatory and immune-modulating activities. Recently, a new intranasal HA formulation has been proposed: a supramolecular system containing lysine hyaluronate, thymine and sodium chloride (T-LysYal®). This randomized study investigated whether intranasal T-LysYal® (RinoLysYal®, Farmigea, Italy) was able to reduce symptom severity, endoscopic features, and nasal cytology in 83 patients (49 males and 34 females mean age 45.4±6.2 years) treated with FESS. All patients were treated with isotonic saline solution for 4 weeks, and a sub-group (active group) was also treated with intranasal T-LysYal®. Patients were visited at baseline, after treatment, and after 4-week follow-up. Intranasal T-LysYal® treatment significantly reduced the quote of patients with symptoms, endoscopic features, and inflammatory cells in comparison to isotonic solution. In conclusion, the present study demonstrates that intranasal T-LysYal® is able to significantly improve patients after FESS and its effect is long lasting.

NASAL cytology: practical aspects and clinical relevance.

Nasal cytology is a simple and safe diagnostic procedure that allows to assess the normal and pathological aspects of the nasal mucosa, by identifying and counting the cell types and their morphology. It can be easily performed by a nasal scraping followed by May-Grunwald-Giemsa staining and optical microscopy reading. This procedure allows to identify the normal cells (ciliated and mucinous), the inflammatory cells (lymphocytes, neutrophils, eosinophils, mast cells), bacteria, or fungal hyphae/spores. Apart from the normal cell population, some specific cytological patterns can be of help in discriminating among various diseases. Viral infections, allergic rhinitis, vasomotor rhinitis and overlapping forms can be easily identified. According to the predominant cell type, various entities can be defined (named as NARES, NARESMA, NARMA). This implies a more detailed knowledge and assessment of the disease that can integrate the standard diagnostic procedures. Nasal cytology also represents a useful research tool for diagnosis and therapy.

Nasal irrigation with Nasir® in children: a preliminary experience on nasal cytology.

Allergic rhinitis (AR) and upper airway respiratory infections are frequent in children, and both have a relevant impact on some social aspects, including school attendance and performance, sleep, quality of life (also of the parents), and costs. Saline nasal irrigation is widely employed to reduce nasal congestion and mucopurulent secretion, to stimulate cleansing of the nasal and paranasal cavities, and to induce restoration of mucociliary clearance. The present study evaluated the effects of nasal irrigation on nasal cytology, using the new device Nasir® in 66 children (40 males, 26 females, mean age 7.31±1.7 years, age range 4-17 years) with allergic rhinitis. The patients were treated with nasal irrigation with warm (36°C) Nasir® (250 mL sacs of premixed solution): one sac twice daily for 12 days. Nasal irrigation significantly reduced the neutrophilic infiltrate (baseline median value 2.8±0.7; post treatment value 2±0.5; p less than 0.05). In addition, there was a reduction of eosinophil infiltrate (T0= 3.2±1.1; T1= 2.6±1.2; p= less than 0.05). There was no significant change with regard to bacteria (T0= 2.7±0.9; T1= 2.3±1.02; p= 0.17). In conclusion, this pilot study reports that nasal irrigation with Nasir® might be useful to attenuate upper airway inflammation.
