Contains fulltext : 300031.pdf (Publisher’s version ) (Open Access), OBJECTIVE: This study aims to assess the product performance of a new moldable peristomal adhesive with corresponding heating pad designed to facilitate and improve automatic speaking valve (ASV) fixation for hands-free speech in laryngectomized patients. METHODS: Twenty laryngectomized patients, all regular adhesive users with prior ASV experience, were included. Study-specific questionnaires were used for data collection at baseline and after two weeks of moldable adhesive use. The primary outcome parameters were adhesive lifetime during hands-free speech, use and duration of hands-free speech, and patient preference. Additional outcome parameters were satisfaction, comfort, fit, and usability. RESULTS: The moldable adhesive enabled ASV fixation adequate for hands-free speech in the majority of participants. Overall, the moldable adhesive significantly increased adhesive lifetime and duration of hands-free speech compared to participants' baseline adhesives (p < 0.05), regardless of stoma depth, skin irritation, or regular use of hands-free speech at baseline. The participants who preferred the moldable adhesive (55% of participants) experienced a significant increase in the adhesive lifetime (median of 24 h, range 8-144 h) and improved comfort, fit, and ease of speech. CONCLUSION: The moldable adhesive's lifetime and functional aspects, including the ease of use and custom fit, are encouraging outcomes and enable more laryngectomized patients to use hands-free speech more regularly.

Monitoring livestock feeding behavior may help assess animal welfare and nutritional status, and to optimize pasture management. The need for continuous and sustained monitoring requires the use of automatic techniques based on the acquisition and analysis of sensor data. This work describes an open dataset of acoustic recordings of the foraging behavior of dairy cows. The dataset includes 708 h of daily records obtained using unobtrusive and non-invasive instrumentation mounted on five lactating multiparous Holstein cows continuously monitored for six non-consecutive days in pasture and barn. Labeled recordings precisely delimiting grazing and rumination bouts are provided for a total of 392 h and for over 6,200 ingestive and rumination jaw movements. Companion information on the audio recording quality and expert-generated labels is also provided to facilitate data interpretation and analysis. This comprehensive dataset is a useful resource for studies aimed at exploring new tools and solutions for precision livestock farming.

Introduction: The aim of this case series was to evaluate the necrosis of teeth adjacent to the site of mandibulotomy or mandibulectomy in a cohort of patients suffering from head and neck cancers. Methods: Fourteen patients who underwent segmental mandibulectomy or paramedian mandibulotomy for oral, oropharynx or major salivary gland cancer and a total of 23 teeth were included in this case series. Twelve patients underwent adjuvant head and neck radiotherapy. Cold sensitivity pulp testing and/or electric pulp testing were performed on teeth at the margin of mandibulectomy and on teeth adjacent to mandibulotomy after surgery. A “positive” response was considered the healthy state, and “negative” was considered the diseased state of the tooth. Results: The 10 patients who underwent mandibulotomy had 12 teeth with a negative response. The 4 patients treated by mandibulectomy had two positive and three negative responses to cold and electric pulp tests. Fifteen out of 23 teeth (65.2%) showed a negative response to sensitivity testing. Conclusions: Tooth necrosis seems to be a common event after mandibulectomy and mandibulotomy. Clinical Relevance: To avoid post-surgery complications, performing root canal therapy before surgery on the teeth adjacent to the surgical site could be an appropriate strategy.

PFAPA syndrome belongs to the family of autoinflammatory disorders, and its pathophysiology remains mysterious; it is probably related to oligo or polygenic mechanisms and recurs over a variable length of time in combination with clinical signs relating to the oral cavity and cervical lymph nodes. Pharyngitis and cervical adenitis are distinctive manifestations of PFAPA syndrome, which is largely underdiagnosed among the non-hereditary causes of pediatric fevers and is sometimes confused with other hereditary periodic fevers, primary or acquired immunodeficiency disorders, and cyclic neutropenia. Unfortunately, options for successfully managing the disease and stopping the recurrence of fevers are limited. Interventions focused on innate immunity cells might enhance their response and convey possible benefits for these children; how the microbiome interacts with peculiar genotypes to influence PFAPA expression is an open question, and the acquisition of metagenomic data will create opportunities to examine the evolutionary tuning of the microbiome to the host and shed light on the manifold human–microbiome partnership.

Clival chordomas are rare but aggressive skull base tumors that pose significant treatment challenges and portend dismal prognosis. The aim of this study was to highlight the advantages and limitations of available treatments, to furnish prognostic indicators, and to shed light on novel therapeutic strategies. We conducted a retrospective study of clival chordomas that were surgically treated at our institution from 2003 to 2022; for comparison purposes, we provided a systematic review of published surgical series and, finally, we reviewed the most recent advancements in molecular research. A total of 42 patients underwent 85 surgeries; median follow-up was 15.8 years, overall survival rate was 49.9% at 10 years; meanwhile, progression-free survival was 26.6% at 10 years. A significantly improved survival was observed in younger patients (<50 years), in tumors with Ki67 ≤ 5% and when adjuvant radiotherapy was performed. To conclude, clival chordomas are aggressive tumors in which surgery and radiotherapy play a fundamental role while molecular targeted drugs still have an ancillary position. Recognizing risk factors for recurrence and performing a molecular characterization of more aggressive lesions may be the key to future effective treatment.

Endoscopic transsphenoidal surgery is a novel surgical technique requiring specific training. Different models and simulators have been recently suggested for it, but no systematic review is available. To provide a systematic and critical literature review and up-to-date description of the training models or simulators dedicated to endoscopic transsphenoidal surgery. A search was performed on PubMed and Scopus databases for articles published until February 2023; Google was also searched to document commercially available. For each model, the following features were recorded: training performed, tumor/arachnoid reproduction, assessment and validation, and cost. Of the 1199 retrieved articles, 101 were included in the final analysis. The described models can be subdivided into 5 major categories: (1) enhanced cadaveric heads; (2) animal models; (3) training artificial solutions, with increasing complexity (from “box-trainers” to multi-material, ct-based models); (4) training simulators, based on virtual or augmented reality; (5) Pre-operative planning models and simulators. Each available training model has specific advantages and limitations. Costs are high for cadaver-based solutions and vary significantly for the other solutions. Cheaper solutions seem useful only for the first stages of training. Most models do not provide a simulation of the sellar tumor, and a realistic simulation of the suprasellar arachnoid. Most artificial models do not provide a realistic and cost-efficient simulation of the most delicate and relatively common phase of surgery, i.e., tumor removal with arachnoid preservation; current research should optimize this to train future neurosurgical generations efficiently and safely.

Objective: Fine needle aspiration cytology (FNAC) is a well-established diagnostic procedure for head and neck masses not clearly originating from mucosal or cutaneous surfaces. We analysed head and neck masses evaluated over a 2-year period, to assess the reliability of FNAC for the evaluation of malignancy. Methods: We enrolled all patients undergoing FNAC, from April 2013 to July 2015, in a single service of a large Italian university hospital. Relevant clinical data and ultrasonographic parameters of the lesions were recorded. We performed both conventional and thin-prep smears. Clinical presentation, ultrasonographic features and final cytology diagnoses were analysed and correlated with histology. Results: The series included 301 lesions in 285 patients, with a single (94.4%) or two (5.6%) lesions. Only eight samples were considered non-diagnostic/inadequate (2.6%). Among the cases, 139 FNAC (46.1%) underwent surgery. Cytological-histological correspondence was found in 89% of the cases. Concerning malignancy, we documented less than 4% false positives and less than 2.5% false negatives, with 92.7% sensitivity and 94.6% specificity. Conclusion: FNAC diagnosis can be highly specific. Most importantly, it is highly reliable in assessing malignancy, thus defining the priority and guiding the management procedures.

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. Summary: 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.

For survivors of severe COVID-19 disease, having defeated the virus is just the beginning of an uncharted recovery path. What follows after the acute phase of SARS-CoV-2 infection depends on the extension and severity of viral attacks in different cell types and organs. Despite the ridiculously large number of papers that have flooded scientific journals and preprint-hosting websites, a clear clinical picture of COVID-19 aftermath is vague at best. Without larger prospective observational studies that are only now being started, clinicians can retrieve information just from case reports and or small studies. This is the time to understand how COVID-19 goes forward and what consequences survivors may expect to experience. To this aim, a multidisciplinary post-acute care service involving several specialists has been established at the Fondazione Policlinico Universitario A. Gemelli IRCSS (Rome, Italy). Although COVID-19 is an infectious disease primarily affecting the lung, its multi-organ involvement requires an interdisciplinary approach encompassing virtually all branches of internal medicine and geriatrics. In particular, during the post-acute phase, the geriatrician may serve as the case manager of a multidisciplinary team. The aim of this article is to describe the importance of the interdisciplinary approach––coordinated by geriatrician––to cope the potential post-acute care needs of recovered COVID-19 patients.

Background: Fatigue with reduced tolerance to exercise is a common persistent long-lasting feature amongst COVID-19 survivors. The assessment of muscle function in this category of patients is often neglected.Aim.: To evaluate the potential impact of a daily supplementation based on amino acids, minerals, vi-tamins, and plant extracts (Apportal (R)) on muscle function, body composition, laboratory parameters and self-rated health in a small group of COVID-19 survivors affected by fatigue.Methods: Thirty participants were enrolled among patients affected by physical fatigue during or after acute COVID-19 and admitted to the post-COVID-19 outpatient service at Fondazione Policlinico Gemelli in Rome between 1st March 2021 and 30th April 2021. All participants were evaluated at first visit (t0) and at control visit (t1), after taking a daily sachet of Apportal (R) for 28 days. Muscle function was analyzed using hand grip strength test, exhaustion strength time and the number of repetitions at one -minute chair stand test. Body composition was assessed with bioelectrical impedance analysis (BIA). Laboratory parameters, including standard blood biochemistry and ferritin levels, were evaluated at the first visit and during the control visit. A quick evaluation of self-rated health, before COVID-19, at t0 and t1, was obtained through a visual analogue scale (VAS). Results: Participants aged 60 years and older were 13 (43%). Females represented the 70% of the study sample. Participants hospitalized for COVID-19 with low -flow oxygen supplementation represented the 43.3% of the study sample while 3.3% received noninvasive ventilation (NIV) or invasive ventilation. Hand grip strength improved from 26.3 Kg to 28.9 Kg (p < 0.05) at t1 as compared to t0. The mean time of strength exhaustion increased from 31.7 s (sec) at t0 to 47.5 s at t1 (p < 0.05). Participants performed a higher number of repetitions (28.3 vs. 22.0; p < 0.05) during the one-minute chair stand test at

Diagnosis and management of sinonasal complications of dental diseases or treatment (SCDDT) may be challenging. We aimed to report our real-life experience in patients treated with endoscopic endonasal approach describing data about symptoms, etiology, extension of the disease and success rate. We evaluated retrospectively data about 262 patients diagnosed as SCDDT and managed from August 2015 to May 2022. In 44.65% cases, maxillary sinus complications were determined by a dental disorder; the remaining 55.34% of cases were iatrogenic. Patients were managed according to our multidisciplinary protocol including ENT, dental, and radiological evaluation. Treatments were planned with a personalized approach, based on the patient’s clinical characteristics; all patients were treated with an endonasal endoscopic mini-invasive conservative approach. Combined dental treatment was performed simultaneously in 152/262 (58%) of patients; in the remaining cases, it was postponed after surgery. The overall treatment success rate (symptom resolution and endoscopically observed maxillary sinus healing) was 96.5%. At 15 days after surgery, we observed a significant improvement in the quality of life. The mean post-operative Sinonasal outcome test-22 (SNOT-22) score was significantly lower compared to baseline (6 versus 43.4; p < 0.05). Our study showed that endoscopic sinus surgery can be a successful procedure for treatment of SCDDT, leading to fast resolution of sinonasal symptoms and improving the quality of life. Furthermore, the technique allows removal of migrated dental material or dental implants even in challenging cases.

The aim of the study was to evaluate survival in patients with advanced glottic laryngeal squamous cell carcinoma treated by bioradiotherapy (BioRT) with cetuximab and eventual salvage surgery (group A, n = 66) or upfront surgery (total laryngectomy or near-total laryngectomy) with or without postoperative radiotherapy (PORT) (group B, n = 66). The predictive role of HER1 expression in the bioselection of tumors was evaluated. Relapse-free (RFS), metastasis-free (MFS), overall (OS) survivals, salvageability, and rates of larynx preservation were analyzed. The two groups were balanced by propensity score method on their baseline characteristics. No significant differences in RFS and OS were found, while MFS results were significantly higher in group A (p = 0.04). Group A showed a 22% reduction in the probability of nodal metastasis (p = 0.0023), mostly in tumors with higher HER1 expression. The salvageability with TL at 3 years was 54% after prior BioRT and 18% after prior upfront NTL (p < 0.05). BioRT with cetuximab showed a reduction in the risk of lymph node relapse, particularly in the case of HER1 positive tumors, and it allowed to achieve a higher rate of functional larynx preservation and a higher salvageability compared with upfront surgery. HER1 analysis could be clinically useful in the bioselection of tumors that may benefit from BioRT with cetuximab, particularly in those with neck node metastatic propensity.

Purpose: Irreversible bilateral sensorineural hearing loss is a common side effect of platinum compounds. Because of the extended overall survival, a prolonged hearing surveillance and management of hearing impairments are emerging concerns for pediatric oncology. Methods: In this retrospective observational study, we enrolled 38 children out of 116 treated at our institution by chemotherapy (cisplatin and/or carboplatin) with or without irradiation between 2007 and 2014, submitted to hearing monitoring before every cycle of chemotherapy, and who completed a 5-year long-term audiological follow-up. Chemotherapy regimens, demographic findings, cumulative doses, and cranial irradiation were compared. Results: At the end of 5-year follow-up, ototoxicity was significantly increased compared to that observed at the end of chemotherapy (52.5% vs 39.5%, p < 0.001). A late onset of hearing loss was experienced in 13.1% of children, while in 26.3% progressive hearing loss was measured. Deafness at the end of chemotherapy and irradiation were significant prognostic factors for late ototoxicity outcomes (Odds Ratio 7.2—CI 1.67–31.1—p < 0.01 and 5.25—CI 1.26–21.86—p < 0.01 respectively). No significant differences were found between cisplatin and combined treatment (i.e., cisplatin shifted to carboplatin during monitoring for the onset of ototoxicity) and ototoxicity was not associated with platinum compounds cumulative dose (p > 0.05). 13.1% of children needed hearing aids at the end of follow-up. Conclusion: Long-term monitoring of at least 5 years prevents the harmful effects of hearing deprivation identifying late onset/progressive hearing loss after platinum compound chemotherapy in children thanks to early hearing rehabilitation, especially in those who underwent multimodal therapy or subjected to irradiation.

Background: In order to evaluate the efficacy of intranasal mometasone furoate in patients with non-allergic rhinitis (NAR), a real-life, observational, prospective study is performed. Methods: Thirty-one patients (age 18-64 years) receive intranasal (mometasone furoate, 200 mu g b.i.d. for 15 consecutive days per month for 6 consecutive months), plus isotonic nasal saline. The cytologic pattern of local inflammation, nasal airflow, through peak nasal inspiratory flow (PNIF), quality of life (QoL), through the rhinitis quality of life questionnaire (RQLQ), the sinonasal outcome test (SNOT-22), the short-form 36-item health survey (SF-36v2), and the combined symptom medication score (CSMS), and, finally, olfactory function, through Sniffin' sticks-16 identification test (SSIT-16), are evaluated at baseline and after treatment. Results: NARNE is the most frequent cytological pattern (48% of the total sample). The therapeutic response shows improvement in olfactory function and QoL. Conclusions: The results of this study confirm that intranasal mometasone furoate is an effective treatment for patients with NAR.

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. Summary: 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 c

The role of elective neck dissection during salvage surgery in patients with a clinically negative neck (cN0) is still discussed. The main objective of this work was to estimate the prevalence and predictive factors of occult neck nodes metastasis; we therefore aimed to evaluate the survival rate and the main oncologic outcomes of cN0 patients who underwent salvage total laryngectomy and elective bilateral neck dissection. In this retrospective observational study, we enrolled 80 cN0 patients affected by recurrent laryngeal cancer and who underwent salvage total laryngectomy and bilateral selective elective neck dissection. Several parameters were collected in order to find prognostic factors; finally, postoperative complications were reviewed and survival analysis was performed. Occult lymph node metastases were reported in 18 out of 80 patients (22.5%). Significant statistical correlation between lymphovascular invasion (p = 0.007), perineural invasion (p = 0.025) and occult nodal metastasis was found. Other variables (glottic subsite of recurrence, clinical T, pathological T, previous chemotherapy) were not significantly predictive of occult nodal metastasis. The 5-year OS, DSS, and RFS were 50.4%, 64.7%, and 63.4%, respectively. In conclusion, our single-institution data on a large cohort of patients, suggest performing routinely elective selective bilateral neck dissection during salvage total laryngectomy in cN0 patients due to the biological attitude of the tumor to spread to cervical nodes, considering an acceptable complications rate.

Eosinophilic otitis media (EOM) is a difficult-to-treat otitis media characterized by eosinophilic accumulation in the middle ear mucosa and effusion. It is resistant to conventional treatments and strongly associated with asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). The aim of our study is to evaluate the effectiveness of biologics drugs in the control of EOM. This is a retrospective no-profit real-life observational study, involving patients affected by refractory EOM and in treatment with different biologics for concomitant severe eosinophilic asthma or severe uncontrolled CRSwNP (Dupilumab: n = 5; Omalizumab: n = 1; Mepolizumab: n = 1; Benralizumab: n = 1). We analyzed data at baseline and at the 6-month follow-up, including specific nasal and otological parameters. We observed an improvement of all nasal outcomes, including NPS, SNOT-22, VAS, and smell function. Regarding specific otological parameters, we observed a significant reduction in the mean value of COMOT-15 score and of Otitis Severity Score at 6-month follow-up compared to baseline (p < 0.05). Finally, we observed an improvement in terms of air conduction hearing levels during the treatment. Our results demonstrated that anti type-2 inflammatory pathway biologics can be effective in improving symptoms control and in reducing the severity of eosinophilic otitis media when treating coexisting type-2 diseases, such as asthma and or CRSwNP.

HHT affects one in 5000 people and occurs in all the ethnic groups and areas. It is also known as the Rendu-Osler-Weber disease and it is an inherited autosomal dominant genetic disorder, characterized by vascular abnormalities. Epistaxis, specifically recurrent and spontaneous nosebleeds, has been assessed as one of the most common, if not the most common clinical manifestation in HHT patients. The burden related to this manifestation has both psychological and physical consequences, especially since the treatment options follow a ladder that might bring to surgery and more invasive therapies. The EQ-VAS questionnaire allows us to adequately assess and classify HHT patients based on the intensity and type of epistaxis-related symptoms. This same questionnaire, which is submitted to patients during each evaluation for the benefit of anamnestic supplementation, includes both a question about the presence or absence of anemia and one about whether a red cell transfusion has been performed in the past months or since the last outpatient visit. As a matter of fact, chronic nosebleed, although mild to moderate, can lead to anemia within months or years and, in general, to a poor quality of life. Patients who have to undergo iron supplementation treatments often face the almost inevitable side effects that this therapy entails (diarrhea, constipation, nausea, persistent metallic taste, abdominal pain, etc.). Although numerous treatment options are available for patients with epistaxis phenotype, from topical to surgical, we believe, based on the successes achieved in the follow up of HHT patients at our center, that a multidisciplinary collaboration is essential to identify the patients who can benefit most from each treatment.

The experience of our center with patients who, after having overcome the SARS-CoV19 infection, manifested olfactory disorders includes 1952 patients who were evaluated, according to the protocol established in multidisciplinary agreement with internal medicine and infectious disease specialists, through ENT physical examinatio, questionnaires, olfactometry and gustometry (before and after treatment). Our goal was to evaluate: the prevalence of smell and taste disorders in patients affected by SARSCoV19, the resolution of the mentioned disorder based on the treatment protocols and eventually a possible correlation with patients not affected by the SARS-CoV19 infection. Our evaluation method included: Chemosensory Complaint Score, three VAS scales for olfactory and gustatory dysfunction and nasal obstruction symptoms, full ENT evaluation (rhinoscopy, oropharyngoscopy, evaluation of larynx and tympanic membranes). In the context of the DH PostCovid, an olfactory deficit was observed in 24.3% of cases; the questionnaire submitted to the patients during the acute phase of the infection tended to overestimate the incidence of the symptoms, but this data is likely related to the psychological impact of the disease itself during the early stages of the pandemic. In a period ranging from 2 to 9 months (M 5.5 months), we found a subjective and olfactometrically detected recovery of the olfactory function in almost all patients (98.6%); in only one case the recovery was obtained 13 months after the first evaluation. Among these patients, 65% of them regained the olfactory function during the first 3 months of therapy. Our therapy protocol consisted of: either topical use of glyceritic acid plus mannitol for topical use in case of inflamed nasal mucosa or crosslinked ialuronic acid for topical use in case of atrophic rhinitis together with citicoline 1000mg per os and olfactory rehabilitation. Once having obtained these data, and keeping in mind that the therapy was personaliz

Objectives: To confirm the data reported in our previous studies on the analysis of the variability of the electroglottographic signal in the pathological voice; to evaluate possible differences in variability between organic and functional pathologies; to identify any distinctive/typical EGG patterns for these pathologies. Methods: One hundred twenty-five subjects were enrolled (36 euphonic and 89 pathological: 24 functional dysphonia, 21 bilateral vocal nodules, 23 unilateral polyps and 21 unilateral cysts). All subjects were studied with videolaryngostroboscopy, spectrographic analysis of voice and electroglottography (EGG). The EGG signal variability was then investigated using amplitude-speed combined analysis, by means of a proprietary software algorithm. Amplitude and Speed variation were expressed as a new parameter, the Variability Index (VI), calculated both for the whole EGG signal recorded (VI-tot) and in each phase of the glottic cycle (VI-Q, absolute value; VI-Q%, percentage value). Results: In the comparison of VI values between pathological and normal groups, VI-tot and VI-Q2% (which corresponds to the final phase of vocal fold contact) were significantly greater in pathological subjects (P= 0.002). The comparison of VI values among subgroups of the various pathologies showed a difference for VI-tot (P< 0.0001) and VI-Q2% (P= 0.001); this difference was more marked in the cysts than in the functional dysphonia. The cut-off values of VI-tot and VI-Q2% were 0.191 and 18.17%, respectively (sensitivity and specificity 65.2% and 66.7% for VI-tot and 84.3% and 77.8% for VI-Q2%). Conclusions: The variability of the EGG signal investigated through the combined analysis of the amplitude and the speed of vibration using a proprietary algorithm software has proved useful not only to distinguish the normal voice from the pathological voice, but also to characterize which phases are more altered in the various voice pathologies studied, both functional and org

Objective The aim of our study was to analyze the montelukast effectiveness in improving oculonasal symptoms, patient‐reported outcomes (PROs), and eosinophilic biomarkers in patients with nonallergic rhinitis eosinophilic syndrome (NARES). Methods We enrolled prospectively 80 symptomatic patients treated with 10 mg once a day of montelukast in monotherapy for 2 months. All patients were investigated before and after treatment. Nasal symptoms (nasal obstruction, rhinorrhoea, sneezing, nasal itching), ocular symptoms (redness/puffiness, watery eyes), and other PROs (olfactory dysfunction, difficulty going to sleep, nighttime awakenings, and nasal congestion on awakening) were scored by visual analogic scale. The following clinical scores were assessed: Total Nasal Symptom Score (T4NSS), Total Ocular Symptom Score (T2OSS), Total Symptom Score of Patient‐Reported Outcomes (TSS‐PROs), and a Composite Symptoms Score (CSS). Patients were classified as responders when a reduction of at least 50% of the CSS was observed. Before and after treatment, the eosinophilic biomarkers in nasal lavage were analyzed: nasal eosinophilia (number of eosinophils per high power field), eotaxin‐1 and eotaxin‐2. Results After treatment, significant reductions were observed for all the symptom scores. Forty‐two of 78 patients were considered responders. A significant reduction of eosinophils in nasal mucosa and of levels of eotaxin‐1 and eotaxin‐2 in nasal lavage were observed after treatment in responder patients. Patients with asthma had an increased probability to be responders. Conclusion NARES patients may benefit from treatment with montelukast. In particular, the presence of concomitant asthma may be predictive of a greater efficacy.

The cross-talk between oxidative stress and inflammation seems to play a key role in noise-induced hearing loss. Several studies have addressed the role of PPAR receptors in mediating antioxidant and anti-inflammatory effects and, although its protective activity has been demonstrated in several tissues, less is known about how PPARs could be involved in cochlear dysfunction induced by noise exposure. In this study, we used an in vivo model of noise-induced hearing loss to investigate how oxidative stress and inflammation participate in cochlear dysfunction through PPAR signaling pathways. Specifically, we found a progressive decrease in PPAR expression in the cochlea after acoustic trauma, paralleled by an increase in oxidative stress and inflammation. By comparing an antioxidant (Q-ter) and an anti-inflammatory (Anakinra) treatment, we demonstrated that oxidative stress is the primary element of damage in noise-induced cochlear injury and that increased inflammation can be considered a consequence of PPAR down-regulation induced by ROS production. Indeed, by decreasing oxidative stress, PPARs returned to control values, reactivating the negative control on inflammation in a feedback loop.

Objectives: The primary end point of this study was to evaluate the impact of bile acids on severity of laryngo-pharyngeal reflux (LPR) and the possible correlation with esophagitis and upper airway malignancies. The second end point was to evaluate if salivary bile acids and molecules other than pepsin might serve as diagnostic biomarkers of LPR. Design: Observational prospective comparative study. Setting: Otorhinolaryngology unit of a tertiary hospital. Participants: Sixty-two consecutive adult outpatients suspected of LPR. Main outcome measures: Bile acids, bilirubin and pepsinogen I-II were measured in saliva. Patients underwent pH metry and based on the results of bile acids were subdivided as acid, mixed and alkaline LPR. Results: Significantly higher Reflux Findings Score (RFS) and Reflux Symptoms Index (RSI) were seen in patients with alkaline and mixed LPR compared to acid LPR. Salivary bile acids >1 µmol/L seem to be a reliable indicator of the severity of LPR. Compared to those without, patients with esophagitis or a history of upper airway malignancy have high concentrations of bile acids in saliva. Among the molecules studied, bile acids were the most suitable for diagnosis of LPR, with a sensitivity of 86% and a positive predictive value of 80.7%. Conclusions: Our data suggest that high concentrations of bile acids are associated with higher values of RSI and RFS in LPR as well as a higher risk of esophagitis and history of upper airway malignancies. We finally observed that bile acids provided the best biometric parameters for diagnosis of LPR among the molecules tested.

Introduction: The novel coronavirus SARS-Cov-2 can infect the respiratory tract causing a spectrum of disease varying from mild to fatal pneumonia, and known as COVID-19. Ongoing clinical research is assessing the potential for long-term respiratory sequelae in these patients. We assessed the respiratory function in a cohort of patients after recovering from SARS-Cov-2 infection, stratified according to PaO2/FiO2 (p/F) values. Method: Approximately one month after hospital discharge, 86 COVID-19 patients underwent physical examination, arterial blood gas (ABG) analysis, pulmonary function tests (PFTs), and six-minute walk test (6MWT). Patients were also asked to quantify the severity of dyspnoea and cough before, during, and after hospitalization using a visual analogic scale (VAS). Seventy-six subjects with ABG during hospitalization were stratified in three groups according to their worst p/F values: above 300 (n = 38), between 200 and 300 (n = 30) and below 200 (n = 20). Results: On PFTs, lung volumes were overall preserved yet, mean percent predicted residual volume was slightly reduced (74.8 ± 18.1%). Percent predicted diffusing capacity for carbon monoxide (DLCO) was also mildly reduced (77.2 ± 16.5%). Patients reported residual breathlessness at the time of the visit (VAS 19.8, p < 0.001). Patients with p/F below 200 during hospitalization had lower percent predicted forced vital capacity (p = 0.005), lower percent predicted total lung capacity (p = 0.012), lower DLCO (p < 0.001) and shorter 6MWT distance (p = 0.004) than patients with higher p/F. Conclusion: Approximately one month after hospital discharge, patients with COVID-19 can have residual respiratory impairment, including lower exercise tolerance. The extent of this impairment seems to correlate with the severity of respiratory failure during hospitalization.

Objective: To describe a remote approach used with patients with voice prosthesis after laryngectomy during the COVID-19 pandemic and the resulting clinical outcomes in terms of voice prosthesis complications management, oncological monitoring, and psychophysical well-being. Study Design: Prospective cohort study. Setting: Otolaryngology Clinic of the University Polyclinic A. Gemelli, IRCCS Foundation. Subjects and Methods: All patients with voice prosthesis who underwent laryngectomy followed by our institute were offered enrollment. Patients who agreed to participate were interviewed to inquire about the nature of the need and to plan a video call with the appropriate clinician. Before and 1 week after the clinician’s call, patients were tested with the Hospital Anxiety and Depression Scale. Degrees of satisfaction were investigated with a visual analog scale. A comparison between those who accepted and refused telematic support was carried out to identify factors that influence patient interest in teleservice. Results: Video call service allowed us to reach 37 (50.68%) of 73 patients. In 23 (62.16%) of 37 cases, the video call was sufficient to manage the problem. In the remaining 14 cases (37.83%), an outpatient visit was necessary. Participants who refused telematic support had a significantly shorter time interval from the last ear, nose, and throat visit than patients who accepted (57.95 vs 96.14 days, P =.03). Video-called patients showed significantly decreased levels of anxiety and depression (mean Hospital Anxiety and Depression Scale total score pre– vs post–video call: 13.97 vs. 10.23, P <.0001) and reported high levels of satisfaction about the service. Conclusion: Remote approach may be a viable support in the management of patients with voice prosthesis rehabilitation.

There are controversial results about the role of “ex novo” HLA-DR expression by tumor cells and its correlation with the oncological outcomes. Unfortunately, little is known about HLA-DR expression in laryngeal cancer tumor cells. The main purpose of this retrospective study is to strengthen the usefulness of studying “ex novo” HLA-DR expression on tumor cells from primary laryngeal squamous cell carcinoma (LSCC) patients and investigate its correlation with clinical outcome. We analyzed HLA-DR expression by immunohistochemical analysis in 56 patients with LSCC. The “ex novo” HLA-DR expression on laryngeal cancer tumor cells, assessing non-neoplastic LSCC – adjacent tissue, and the association of HLA-DR expression (HLA-DR+) with clinical outcomes were investigated. HLA-DR+ tumor cells were detected in 18/56 LSCC patients (32.1%). All specimens of non-neoplastic laryngeal carcinoma-adjacent tissue resulted HLA-DR negative (HLA-DR-). A statistically significant association was observed between HLA-DR + and well differentiated tumors (G1) (p<0.001). The Kaplan-Meier method showed how HLA-DR+ is significantly associated with both a better disease specific survival (HLA-DR+=100% vs. HLA-DR-=77.4%; p=0.047) and a better relapse free survival (HLA-DR+=100% vs. HLA-DR-=72.3%; p=0.021). Cox regression univariate analysis for death of disease confirmed a higher HR for HLA-DR absence on the surface of epithelial tumor cell [HR:37.489; 95% CI:0.750-18730.776; p=0.253] and for high-grade (G3) tumors [HR:18.601; 95% CI:3.613-95.764; p<0.0001]. Our results confirm that MHC class II HLA-DR expression is activated in a sub-set of LSCC patients. Evaluation of HLA-DR expression in LSCC could be useful for prognosis and future approaches towards personalized therapy.
