Pathophysiological Link Between Chronic Rhinosinusitis and Ear Disease.

PURPOSE OF REVIEW: In the clinical practice, patients affected by chronic rhinosinusitis (CRS) commonly complain of otologic symptoms. This review aims to describe the available literature evidence assessing the relationship between CRS and ear illnesses published in the last 5 years. RECENT FINDINGS: Available evidence suggests a higher prevalence of otologic symptoms in patients suffering from CRS, affecting up to 87% of patients. These symptoms may be related to Eustachian tube dysfunction, which improves after treatment for CRS. A few studies suggested a potential but not confirmed role of CRS in cholesteatoma, chronic otitis media, and sensorineural hypoacusis. A special type of otitis media with effusion (OME) may occur in patients with CRS, which seems to respond well to new biologic therapy. Ear symptoms appear to be highly prevalent in patients with CRS. So far, the available evidence is robust only for Eustachian tube dysfunction, which has been shown to be particularly impaired in CRS patients. Additionally, the Eustachian tube function appears to improve after treatment for CRS. Finally, interesting preliminary data were described for eosinophilic otitis media, as it appears to respond well to the treatment with biologics.

Clinical Evidence of Type 2 Inflammation in Non-allergic Rhinitis with Eosinophilia Syndrome: a Systematic Review.

PURPOSE OF REVIEW: Non-allergic rhinitis (NAR) includes different subtypes, among which NAR with eosinophilia syndrome (NARES) is the most important because of severity of symptoms and the high risk of comorbidities. Its pathophysiology is still object of debate, but a crucial role of chronic eosinophilic inflammation has been recognized. The aim of this review is to critically analyze the current evidence regarding the hypothesis that NARES may be considered a type 2 inflammatory disorder. RECENT FINDINGS: The definition and diagnostic criteria for NARES are not universally shared and adopted, thus generating difficulties in reproducing the results. At present, there is extreme heterogeneity in sampling methods and disagreement in the cut-off of local eosinophilic count to determine a diagnosis of NARES. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standard was applied to identify English-language experimental and clinical articles regarding NARES. The search was performed in April 2021. Twenty-six articles were included. Our data suggest a particular heterogeneity regarding sampling and specific cut-offs adopted for diagnosis of NARES and consensus should be reached. We suggest that eosinophil count should be reported as an absolute value for at least 10 observed rich fields in order to increase the level of standardization. Consensus among authors on this topic should be reached with particular attention to the cut-off for diagnosis. In the future, this limitation may be overcome by the identification of repeatable biomarkers to refine diagnosis and prognosis of NARES. Furthermore, our data strongly suggest that NARES have numerous similarities with clinical features of the most common type 2 diseases such as eosinophilic asthma and chronic rhinosinusitis with nasal polyps (CRSwNP): late onset, association with type 2 comorbidities, selective eosinophilic tissue infiltration, remarkable response to oral and intranasal corticosteroids, and progression in a type 2 CRSwNP.

Otitis media in children: Which phenotypes are most linked to allergy? A systematic review.

BACKGROUND: Allergic rhinitis is a common childhood disease responsible for a major impact on quality of life and healthcare resources. Many hypotheses have been proposed to explain the link between allergy and otitis media, although a definitive mechanism has not been identified yet. One of the major critical points is that authors failed in distinguishing among different phenotypes of middle ear inflammation. This review pointed out literature evidence from the laboratory and clinical experience linking allergy to different phenotypes of otitis media in children. METHODS: We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process. Our search yielded 3010 articles that were finally screened. This resulted in 20 manuscripts of which the full texts were included in a qualitative analysis. We paid particular attention in distinguishing among phenotypes of otitis media. RESULTS: Clinical evidence and analyses of biomarkers suggested that allergy may be linked to some phenotypes of otitis media and, in particular, to otitis media with effusion (OME) and acute re-exacerbations in children with middle ear effusion. It was not possible to perform the analysis for allergy and acute and chronic otitis media because of paucity and heterogeneity of data. CONCLUSION: Allergy should be considered in the diagnostic workup of children with OME as well as OME should be excluded in children with persistent moderate to severe AR. In these cases, clinicians should evaluate prompt and accurate treatment of allergy in improving outcomes, although futures studies are required to increase evidence supporting that anti-allergy treatment may be effective in the recovery and outcome of otitis media with effusion.

Impact of Tracheal Tube on Swallowing in Post-Operative Head and Neck Cancer Patients: Scintigraphic Analysis.

Dysphagia is common in tracheostomized patients who underwent head and neck surgery for cancer treatment. The objective of this study was to evaluate, by means of oropharyngoesophageal scintigraphy (OPES), the impact of an occluded tracheal tube (TT) on swallowing in patients treated for head and neck cancer before hospital discharge, to provide further information to the benefit of out-patient care management. From October 2018 to November 2019, we enrolled 19 tracheostomized patients (6 females and 13 males; mean age 61 years) who underwent primary surgical resection of head and neck tumor and swallowing rehabilitation during hospitalization. All subjects underwent a double-standard OPES, one with occluded tracheal tube and the other without TT, with their tracheal stoma being closed directly by a plaster. For each study, we assessed and compared the following quantitative parameters: oral transit time (OTTsec), pharyngeal transit time (PTTsec), esophageal transit time (ETTsec), oral retention index (ORI%), pharyngeal retention index (PRI%), esophageal retention index (ERI%), and aspiration percentage (AP%). The mean values of OTT, PTT, ORI%, PRI%, and ERI% were abnormal during OPES both with TT and without TT and did not statistically differ between the two tests (p > 0.05). Aspiration was detected in 4 cases out of 19 (21.05%) cases during OPES with TT and in 4/19 (21.05%) cases without TT who showed a mean AP% of 11.4% and 11.5% respectively (p > 0.05). Patients with abnormal AP% (> 0%) during OPES with TT showed aspiration signs without TT. Our study showed that the mere presence of a closed tracheal tube does not impact significantly the oropharyngeal transit of bolus during swallowing. This result suggests the possibility to maintain a small-diameter occluded tracheal tube in place for the postsurgical management of head and neck cancer patients.

Traumatic benign paroxysmal positional vertigo: personal experience and comparison with idiopathic BPPV.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vestibular vertigo, with post-traumatic origin in about 15% of cases. Management and prognosis of traumatic BPPV (T-BPPV) are still debated, especially about recurrence. The aim was to compare T-BPPV to idiopathic (I-BPPV). DESIGN AND STUDY SAMPLE: We analysed data about 795 BPPV patients: 716 idiopathic (90%) and 79 post-traumatic (10%), evaluating clinical history and bedside-examination, treating all patients with repositioning manoeuvres and reassessing them until the resolution of symptoms and nystagmus. RESULTS: Persistence rate in T-BPPV and I-BPPV patients was significantly different (p = 0.0074, OR = 2.31), respectively 12.6% and 5%. Also the rate of bilateral disease (p = 0.0063, OR = 4.72) and multicanalar involvement (p = 0.0183; OR = 4.67) were significantly higher in T-BPPV patients . There were no significant differences in age and sex distribution, side and canal interested. In T-BPPV group, the resolution rate with one manoeuvre was lower than I-BPPV (p = 0.0132: OR: 0,56). Recurrence rate was 38% in the T-BPPV group and 30.6% in the I-BPPV group, without significant difference. CONCLUSIONS: T-BPPV resulted different from I-BPPV in the resolution rate, bilateral or multiple canal involvement and persistence rate. T-BPPV and I-BPPV does not differ for recurrence rate, suggesting that, after resolution, the natural course of post-traumatic and idiopathic BPPV is similar.

Clinical Evidence and Biomarkers Linking Allergy and Acute or Chronic Rhinosinusitis in Children: a Systematic Review.

PURPOSE OF THE REVIEW: We provide a systematic review of experimental and clinical evidences linking allergy to acute, including common cold, and chronic rhinosinusitis in children. Furthermore, we questioned if anti-allergy treatment may prevent the occurrence of rhinosinusitis or improve outcomes of its specific management. RECENT FINDINGS: Allergic rhinitis is a common childhood disease in industrialized countries that is responsible for a major impact on quality of life and healthcare resources. Over the years many authors tried to correlate allergy with comorbidities and in particular to the onset of rhinosinusitis including common cold, even though conflicting results are frequently reached. We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process. Our search yielded 7103 that were finally screened. This resulted in 25 publications of which the full texts were assessed and included in a qualitative analysis per different phenotypes of rhinosinusitis. The evidence suggests that allergy may lead to overall impairment of mechanical and immunological defense function of the nasal mucosa against viruses and that anti-allergy treatment may significantly decrease the number and severity of upper respiratory tract infections including common colds in children. It was not possible to perform the analysis for allergy and post-viral acute rhinosinusitis, bacterial acute rhinosinusitis, and recurrent acute rhinosinusitis because of paucity and heterogeneity of data. Although there is no definitive proof of causation linking allergy to chronic rhinosinusitis, studies lead to suppose that anti-allergy treatment may improve outcomes of specific CRS treatments.

The prevalence of signs and symptoms of laryngopharyngeal reflux and laryngeal precancerous lesions in urban taxi drivers.

PURPOSE: Taxi drivers represent a large group of workers employed in the service sector of transport. Many studies found an increased risk of a range of health disorders in relation to their irregular work shifts, inappropriate diet, drinking and smoking habits and their high exposure to gasoline- and diesel-engine exhaust fumes. The aim of the present study was to assess the sample of a larynx from taxi drivers, considering symptoms and endoscopic signs of laryngopharyngeal reflux (LPR) and precancerous lesions. METHODS: Taxi drivers enrolled (n = 74) were questioned about their nicotine dependence using the Fagerstrom scale. The Reflux Symptom Index (RSI) was administered to screen LPR symptoms. Each subject underwent videolaryngoscopy with Reflux Finding Score (RFS) calculation. Data were compared with those obtained from the control group (n = 102). RESULTS: Taxi drivers' group did not show a significantly greater dependence on cigarette smoking (p < 0.05) based on the Fagerstrom scale. RSI resulted greater or equal to 13 (cut-off for reflux disease) for 28/74 (37.3%) taxi drivers and 14/102 (13.7%) controls, with a statistically significant difference between the two groups (p = 0.0015; OR = 3.14). RFS was greater or equal to 7 (95% certainty of having LPR) in 40/74 (53%) cases and 30/102 (29.4%) controls (p = 0.0010, OR = 2.82). Three taxi drivers (4%) had leucoplastic lesions of the vocal cords worthy of biopsy, which turned out to be infiltrating squamous cell carcinoma on histological examination. CONCLUSIONS: Taxi drivers resulted at risk of LPR and presented high-prevalence laryngeal precancerous lesions and carcinoma.

Is drug consumption correlated with benign paroxysmal positional vertigo (BPPV) recurrence?

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo and its recurrence is fairly common. Several studies correlated the pathophysiological role of different comorbidities-such as diabetes, osteoporosis, vascular, psychiatric and autoimmune diseases-in the development and recurrence of BPPV. The aim of this study is to analyse the pharmacological history of patients with idiopathic BPPV in relation to the risk of developing recurrence. METHODS: Data regarding 715 patients aged 12 to 87 years (62.7 ± 14) with non-traumatic BPPV were retrospectively evaluated. These refer to the Vestibular Service, day clinic, and were collected over a 4-year period, between 2014 and 2018. RESULTS: Recurrence of BPPV was observed in 220/715 patients (30.76%). A statistically significant correlation (p < 0.006) between recurrence and drug consumption was observed for SNC agents (p = 0.0001), vitamin D (p = 0.0005), PPI (p = 0.0007), thyroid hormones (p = 0.0011), and antihypertensives in single use (p = 0.0031). On the contrary, cholesterol-lowering statin drugs, hypoglycaemic agents, antiplatelet medication, estroprogestins and combination of two or more antihypertensives did not show significant correlation. CONCLUSION: Specific classes of drugs are significantly associated with recurrence: antihypertensive therapy with a singular agent, central nervous system agents, PPIs, vitamin D and thyroid hormones. On the other hand, the lack of correlation between some drugs and recurrence could be linked to the effectiveness of therapy in controlling hypertension, dyslipidaemia and diabetes. Pharmacological history is an essential tool to identify patients at risk of BPPV recurrence.

Pediatric normative data for a novel and fast speech perception test in noise.

OBJECTIVES: Communicating in noisy settings can be difficult due to interference and environmental noise, which can impact intelligibility for those with hearing impairments and those with normal hearing threshold. Speech intelligibility is commonly assessed in audiology through speech audiometry in quiet environments. Nevertheless, this test may not effectively assess hearing challenges in noisy environments, as total silence is rare in daily activities. A recently patented method, known as the SRT50 FAST, has been developed for conducting speech audiometry in noise. This new method enables the acceleration and simplification of free field speech audiometry tests involving competition noise. This study aims to establish normative scores and standardize the SRT50 FAST method as a test for evaluating speech perception in noise in pediatric patients. METHODS: The study included 30 participants with normal hearing, consisting of 11 females and 19 males, ranging in age from 6 to 11 years. A series of speech audiometry tests were conducted to determine the speech reception threshold 50% (SRT50) in competing conditions. This included testing both the fast mode (SRT50 FAST) currently being studied and the traditional method (SRT50 CLASSIC). The SRT50, or Signal to Noise Ratio (SNR) at which 50% of speech recognition occurred, was investigated for both methods. RESULTS: The mean SRT50 FAST test score was -2.69 (SD = 3.15). The dataset exhibited a normal distribution with values ranging from 3.60 to -8.60. Since the scores are expressed in SRT, higher scores indicate poorer performance. We have established a threshold of 3.60 as the upper limit of the normal range, therefore, patients with scores above this threshold are considered to have abnormal results. CONCLUSIONS: This study aimed to establish normative data for the evaluation of free field speech in noise recognition using the SRT50 FAST method in the pediatric population. This method accurately investigates the necessary signal-to-noise ratio for achieving 50% recognition scores with bisyllabic words in a quick manner. The ultimate objective is to employ this test to identify the optimal configuration of hearing rehabilitation devices, particularly for pediatric patients with hearing aids and/or cochlear implants. Additionally, it can be used to assess pediatric patients with unilateral hearing loss.

Correlation between inflammatory biomarkers and disease control in chronic rhinosinusitis with nasal polyps.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) may have a heterogeneous response to medical/surgical treatments based on endotypes. Data correlating biomarkers and severity of the disease are lacking. We aimed to determine if IL-5 and calprotectin may be useful in defining severity of disease and identifying uncontrolled patients. METHODS: This was a case-control study including 81 patients with diffuse CRSwNP who underwent at least one previous surgery and treated with intranasal steroids. We enrolled 39 uncontrolled patients (SNOT-22 ≥ 40 and two or more cycles of systemic corticosteroids in last year) (Group A) and 42 controlled one (SNOT-22 < 40 and less than two cycles of systemic corticosteroids in last year) (Group B). We analyzed IL-5 and calprotectin in both nasal secretions and nasal polyp tissue. RESULTS: Calprotectin and IL-5 were significantly higher in Group A in both secretions and tissue, and the higher the number of previous surgeries, the higher the levels detected in nasal secretions. At univariate analyses, smoking, asthma, non-steroidal anti-inflammatory drugs-exacerbated respiratory disease (NSAID-ERD), blood eosinophilia, neutrophils, and eosinophils at nasal cytology were significantly associated with uncontrolled disease. Multivariate analyses showed that asthma, NSAID-ERD, and IL-5 in nasal secretion/polyp tissue were significantly related to the risk of uncontrolled disease. CONCLUSIONS: Our data suggest that asthma, NSAID-ERD, and IL-5 in nasal secretions/tissue may be helpful to identify more severe patients, as they are related to the risk of uncontrolled disease. Nonetheless, high levels of calprotectin and neutrophilia were also observed in uncontrolled patients, especially after multiple surgeries.

Music in noise recognition: An EEG study of listening effort in cochlear implant users and normal hearing controls.

Despite the plethora of studies investigating listening effort and the amount of research concerning music perception by cochlear implant (CI) users, the investigation of the influence of background noise on music processing has never been performed. Given the typical speech in noise recognition task for the listening effort assessment, the aim of the present study was to investigate the listening effort during an emotional categorization task on musical pieces with different levels of background noise. The listening effort was investigated, in addition to participants' ratings and performances, using EEG features known to be involved in such phenomenon, that is alpha activity in parietal areas and in the left inferior frontal gyrus (IFG), that includes the Broca's area. Results showed that CI users performed worse than normal hearing (NH) controls in the recognition of the emotional content of the stimuli. Furthermore, when considering the alpha activity corresponding to the listening to signal to noise ratio (SNR) 5 and SNR10 conditions subtracted of the activity while listening to the Quiet condition-ideally removing the emotional content of the music and isolating the difficulty level due to the SNRs- CI users reported higher levels of activity in the parietal alpha and in the homologous of the left IFG in the right hemisphere (F8 EEG channel), in comparison to NH. Finally, a novel suggestion of a particular sensitivity of F8 for SNR-related listening effort in music was provided.

The Effectiveness of Targeted Electrical Stimulation via Cochlear Implant on Tinnitus-Perceived Loudness.

Introduction: The cause of tinnitus improvement in cochlear implant (CI) users is not understood. On the basis that a spatially limited dysfunction in the auditory pathway could cause tinnitus, we used single-channel stimulation to evaluate any variation of tinnitus-perceived loudness and identify the cochlear regions involved. Materials and Methods: It was an observational prospective case-crossover study. After the first mapping, 21 adults with unilateral CI and chronic tinnitus expressed their tinnitus loudness based on the Visual Analog Scale (VAS) score (0-10) at baseline (L0), during a 10 s single-channel stimulation with C-level of electric current (L1) and 30 min after CI activation (L2). Tinnitus reduction [R T = (L0 - L1) × 100/L0] > 50% was considered significant. VAS outcomes were compared between baseline (L0) and (each) single-channel stimulation (L1) to find the channel with the greatest R T (suppressive channel-SC), whose frequency range revealed the cochlear region involved. Seven patients with asymmetric hearing loss underwent the pitch-matching test to identify the actual frequency evoked by the SC. We compared selective (L1) and non-selective (L2) intracochlear stimulation using paired t-test. Preoperative Tinnitus Handicap Inventory (THI) score was compared with those at 1, 6, and 12 months with paired t-tests to evaluate long-term tinnitus perception. Results: We observed a significant reduction of tinnitus loudness during the experimental procedure [L0 (6.4 ± 2.4) vs. L1 (1.7 ± 2.7), p = 0.003]. A total of 15/21 patients (71.4%) had a significant (R T > 50%) and selective improvement, reporting a mean L1 of 0.4 ± 2.0 (p = 0.0001). In 10/15 (66.6%) patients, the SC was in the apical turn, within 1,000 Hz; in 5/15 patients (33.4%) within 4,000 Hz. The cochlear region 125-313 Hz was the most affected by tinnitus improvement (p = 0.0074). Targeted stimulation was more effective than non-selective stimulation [L1 vs. L2 (4.3 ± 2.5), p = 0.0022]. In 3/7 patients, the perceived pitch did not fall within the SC frequency ranges. All patients with selective attenuation described tinnitus as monotone. Patients with non-selective attenuation had polyphonic tinnitus and better THI results after 1 year. Conclusion: Targeted intracochlear electrical stimulation improved chronic tinnitus perception, especially in monotone tinnitus, and the apical region was mainly involved. Our results provide new insights into the pathophysiological mechanisms of tinnitus and targets for innovative therapeutic strategies.

Benign paroxysmal positional vertigo: is hypothyroidism a risk factor for recurrence?

Objective: To investigate the relationship between risk of Benign Paroxysmal Positional Vertigo (BPPV) recurrence and hypothyroidism treated with hormone replacement therapy (HRT). Methods: 797 patients with idiopathic BPPV were divided into two groups: 250 patients with recurrence of BPPV (R-BPPV) and 547 patients without recurrence (NR-BPPV). Regarding patients with thyroid disease on HRT, we collected serum test results of thyroid-stimulating hormone (TSH), free triiodothyronine f-T3, free thyroxine f-T4, thyroglobulin antibodies (TG-Ab) and thyroid peroxidase antibodies (TPO-Ab). Results: Hypothyroidism in long-term HRT was found in 61/250 (24.4%) patients of the R-BPPV group vs 79/547 (14.4%) of the NR-BPPV-group (p = 0.0006). Hashimoto thyroiditis (HT) was associated with recurrence (p < 0.0001). A significant correlation was found between recurrence and level of serum TPO-Ab (p = 0.0117) and TG-Ab (p = 0.0025), but not with mean serum TSH, f-T3 and f-T4. Conclusions: We assume that patients with hypothyroidism in HRT have an increased risk of BPPV recurrence, which is particularly strong for patients with HT and positive thyroid antibodies, suggesting an association between autoimmunity and recurrent vertigo.

Botulinum Neurotoxin A in the Treatment of Pharyngocutaneous Fistula after Salvage Surgery in Head and Neck Cancer Patients: Our Preliminary Results.

Objective: To analyze the effect of intraparotid injection of botulinum neurotoxin A (BoNT-A) on salivary production and the course of pharyngocutaneous fistula (PCF) in post-radiation therapy salvage surgery. Methods: A total of 13 patients who had undergone total laryngectomy or pharyngolaryngectomy were treated with BoNT-A to both parotid glands, within three days from PCF onset. The salivary flow was evaluated using a subjective rating scale as the percentage of normal function from 0% (no saliva) to 100% (normal saliva flow), before injection, every day for 2 weeks, and once a week for three months. PCFs were monitored daily. Results: Spontaneous closure of PCF occurred in 7/13 (53.84%) cases 13.6 days (range: 7-18) after treatment; 6/13 (46.16%) patients needed revision surgery. Salivary flow significantly decreased in all patients seven days after injection (from 67.2% to 36.4%; p < 0.05). Patients who had undergone either conservative or surgical treatment did not differ in salivary flow before injection, whereas the mean percentages of salivary flow calculated at each time point after injection were different (p < 0.05). Conclusions: BoNT-A contributed to the closure of the fistula in most of our cases. The subjective perception of salivary flow predicted the closure of PCF. The mean time to closure may contribute to establishing the timing of PCF surgical treatment.

Voice Telerehabilitation in Iatrogenic Unilateral Vocal Fold Paralysis: From Necessity to Opportunity in the COVID-19 Time.

OBJECTIVE: To evaluate results of telerehabilitation (TR) during the coronavirus disease 2019 pandemic for the treatment of dysphonia caused by permanent post-thyroidectomy unilateral vocal fold paralysis (UVFP). METHODS: Forty subjects with post-thyroidectomy UVFP (onset <1 month) underwent TR. Videostrobolaryngoscopy, acoustic and perceptual voice analysis and patient self-assessment were carried out in person before, at the end of TR and 6 months later. RESULTS: Twenty-five subjects spontaneously recovered full vocal fold motility at some time during follow-up, whereas 15 had a permanent UVFP at the end of the follow-up period. These subjects constituted our study group. At the early posttherapy control 10/15 subjects (66.6%) showed a complete glottal closure, while in 5/15 (33.3%) a glottal gap remained (P = 0.03). These results did not change 6 months after TR. At the late posttherapy control the maximum phonation time improved significantly (P = 0.02). Both post-therapy Voice Handicap Index scores were significantly lower than the pre-therapy ones (P = 0.04). Grade, Breathiness, and Asthenia parameters of the Grade-Roughness-Breathiness-Asthenia-Strain scale improved 6 months after TR (P < 0.05). The number of voice signals suitable for acoustic analysis increased significantly after therapy. Finally, 87% of patients were satisfied with TR. CONCLUSIONS: With careful patient selection, TR may be considered as a promising method for voice therapy in postthyroidectomy UVFP.

Optimizing Pulmonary Outcomes After Total Laryngectomy: Crossover Study on New Heat and Moisture Exchangers.

OBJECTIVE: To evaluate the effects of new devices-heat and moisture exchangers (HMEs) and adhesives-on pulmonary symptoms, subject adherence, quality of life, dermatologic symptoms, and patient satisfaction after laryngectomy. STUDY DESIGN: Prospective crossover study. SETTING: Between December 2020 and April 2021, 40 patients were enrolled who had undergone laryngectomy, routinely used HMEs and adhesive, and were followed in our Department of Otolaryngology-Head and Neck Surgery. METHODS: Patients were allocated into group A (new products) or group B (usual care) for 6 weeks. Then the 2 groups reversed, and each patient acted as his or her own control. Patients kept a diary and cough tally sheet. At baseline and after each 6-week period, 2 questionnaires were administered: EQ-5D (European Quality of Life-5 Dimensions) and CASA-Q (Cough and Sputum Assessment Questionnaire). RESULTS: Six weeks of using new products resulted in the following effects for both groups: (1) a significant reduction in daily forced expectoration and dry coughs, (2) a significant improvement in all domains of the CASA-Q, (3) an increase in adherence to HME use, (4) a significant reduction in shortness of breath and skin irritation, and (5) significantly better scores in the anxiety/depression domain of the EQ-5D. CONCLUSION: Achieving this reduction in patients who were already highly adherent to HME use is clinically relevant and underscores the importance of using better-performing HMEs that can compensate for the humidification deficit. Improving pulmonary symptomatology could reduce patient restrictions in daily life and avoidance of social activity, with a consequent positive effect on quality of life.

Gender-related differences in the prevalence of voice disorders and awareness of dysphonia.

Objective: Considering the impact of dysphonia on public health and the increasing attention to patient-centred care, we evaluated sex-related differences in the prevalence of benign voice disorders, awareness of dysphonia and voice therapy (VT) results. Methods: One hundred and seventy-one patients, 129 females and 42 males, with functional or organic benign dysphonia underwent Voice Handicap Index (VHI), auditory-perceptual dysphonia severity scoring (GRBAS) and acoustic analysis (Jitter%, Shimmer%, NHR) before and after VT. Results: Prevalence of each voice disorder was significantly higher among females. Mean time-to-diagnosis (time elapsed until medical consultation) was not different between males and females. The refusal of therapy and VT adherence (mean number of absences and premature dropout) were similar in the two groups. Pre-VT VHI and "G" parameter were worse in women. The percentage of women with abnormal acoustic analysis was significantly higher. Post-VT VHI gain was higher in women, whereas "G" parameter improvement did not differ by sex. Conclusions: Our study showed a higher prevalence of voice disorders in females. Awareness of dysphonia was not gender related. Females started with worse voice subjective perception and acoustic analysis, but they perceived greater improvement after therapy.

The Role of Allergen-Specific Immunotherapy in ENT Diseases: A Systematic Review.

Previous studies have demonstrated that both subcutaneous (SCIT) and sublingual specific immunotherapy (SLIT) are effective in treating allergic rhinitis (AR). Further studies have evaluated the efficacy of allergen-specific immunotherapy (AIT) on different ear, nose, and throat (ENT) manifestations, in which allergy might have an etiopathogenetic role, such as local allergic rhinitis (LAR), rhinosinusitis (RS), otitis media (OM), and adenotonsillar (AT) disease. Nevertheless, the management of allergy in ENT diseases is still debated. To the best of our knowledge, this is the first systematic review assessing the efficacy of AIT in ENT diseases aside from AR. Literature data confirmed that AIT might be an effective therapeutic option in LAR, although its effect is restricted to studies with short-term follow-up. Furthermore, previous research demonstrated that AIT may improve symptoms and surgical outcomes of chronic rhinosinusitis when used as an adjunctive treatment. Few studies supported the hypothesis that AIT may exert positive therapeutic effects on recurrent upper airway infections as adenotonsillar disease. Finally, some clinical observations suggested that AIT may add some benefits in the management of otitis media with effusion (OME). The results of this systematic review allow us to conclude that the efficacy of AIT in ENT disorders has been only slightly investigated and additional studies are needed.

Benefit of cochlear implantation in a patient with Myhre syndrome.

Myhre syndrome is a rare disorder characterised by short stature, skeletal anomalies, facial dysmorphism and hearing loss (HL), resulting from heterozygous mutations of the SMAD4 gene. We describe the benefits of cochlear implant (CI) in a patient with sensorineural HL carrying a mutation (NM_005359.6: c.1498A>G; p.lle500Val) within the SMAD4 gene, detected by whole-exome sequencing. The CI was inserted through the round window despite otospongiotic abnormalities. Pure-tone audiometry improved up to 20 dBHL. Speech perception in noise (Simplified Noise Reduction - SNR +10) increased from 0% pre implantation with hearing aids to 50% post implantation. The postoperative setting of the electrical stimulation limits yielded an asymmetric map, with lower levels for central electrodes and higher levels for lateral ones. Action potential could not be evoked via medial electrodes, suggesting a cochlear nerve dysfunction. Outcomes related to quality of life and cognitive impairment improved. CI was shown to be an effective auditory rehabilitation strategy.

The evaluation of global cognitive and emotional status of older patients with chronic tinnitus.

OBJECTIVES: Tinnitus is a common symptom largely impactful on quality of life, especially in the elderly. Our aim was to evaluate the efficacy of self-administered screening tests to correlate the severity of subjective perception of tinnitus with emotional disorders and the overall cognitive status. METHODS: Patients aged ≥ 55 years with chronic tinnitus were recruited and submitted to a complete audiological evaluation; Tinnitus Handicap inventory (THI); Hospital Anxiety and Depression Scale (HADS-A and HADS-D) and Mini-Mental State Examination (MMSE). Demographic and audiological features of patients with and without cognitive impairment (MMSE score cut-off of 24/30) were analyzed in order to reveal the relationship among tinnitus, emotional disorders, and cognitive dysfunction. RESULTS: 102 patients were recruited (mean age: 70.4 ± 9.6). THI score was directly related to HADS-A score (r = .63) HADS-D score (r = .66), whereas there was no relationship between tinnitus severity and MMSE (r = .13). CI and n-CI groups did not differ in the characteristics of tinnitus (p > .05), however, hearing threshold (p = .049) and anxious depressive traits measured with HADS-A (p = .044) and HADS-D (p = .016) were significantly higher in the group with cognitive impairment. Furthermore, age ≥ 75 years (p = .002, OR = 13.8), female sex (p = .032; OR = 6.5), severe hearing loss (p = .036; OR = 2.3), and anxiety (p = .029; OR = 9.2) resulted risk factors for CI. Therefore, in CI group MMSE score was inversely related to age (r = -.84). CONCLUSIONS: Cognitive impairment and psychiatric discomfort should be considered in tinnitus patients, related to increasing age, female sex, and severe hearing loss. Thus, self-administered questionnaires can be useful in addressing clinical approach.
