The postharvest phase is an important step in the fruit production chain. Fig is an especially perishable fruit, which has encouraged researchers to study the effects of various substances on the postharvest life of this commodity. The objective of the present work was to evaluate the effects of calcium chloride (CaCl2) and 1methylcyclopropene (1MCP) on the postharvest quality of the 'RoxodeValinhos' fig cultivar. This study aimed to verify the effects of applying a 4% solution of CaCl2 and a 1% solution of 1MCP to figs and evaluating at four different storage times (0, 2, 4, and 6 days). The results showed that a 4% solution of CaCl2 promoted better firmness, and when CaCl2 at 4% solution was applied in combination with 1MCP at 10 μg l1, the maturation index increased. In contrast, the 1MCP treatment alone did not improve the postharvest quality of 'RoxodeValinhos' ripe fig. We conclude that application of 4% solution of CaCl2 and 1MCP at 10 μg l-1 promote firmness and increase maturation index of 'RoxodeValinhos' figs. [ABSTRACT FROM AUTHOR]

In the 2nd century AD, Galen argued that the failure to remove any single 'root' of a malignant tumor could result in a local relapse. After nearly 2 millennia, this problem appears to be even more challenging due to our increased understanding of the complexity of tumor formation and spread. Pathological analysis of tumor margins under a microscope remains the primary and only accepted method for confirming the complete tumor removal. However, this method is not an all-or-nothing test, and it can be compromised by various intrinsic and extrinsic limitations. Among the intrinsic limitations of pathological analysis we recall the pathologist handling, tissue shrinkage, the detection of minimal residual disease and the persistence of a precancerous field. Extrinsic limitations relate to surgical tools and their thermal damage, the different kinds of surgical resections and frozen sections collection. Surgeons, as well as oncologists and radiotherapists, should be well aware of and deeply understand these limitations to avoid misinterpretation of margin status, which can have serious consequences. Meanwhile, new technologies such as Narrow band imaging have shown promising results in assisting with the achievement of clear superficial resection margins. More recently, emerging techniques like Raman spectroscopy and near-infrared fluorescence have shown potential as real-time guides for surgical resection. The aim of this narrative review is to provide valuable insights into the complex process of margin analysis and underscore the importance of interdisciplinary collaboration between pathologists, surgeons, oncologists, and radiotherapists to optimize patient outcomes in oral cancer surgery., Competing Interests: Compliance with Ethical StandardsAuthors declare they have not conflicts of interest., (© The Author(s) 2024.)

Purpose: The aim of this study was to provide an updated European narrative review spanning the last decade, focusing on the cost-effectiveness of cochlear implants (CIs) for adults with severe to profound post-lingual hearing loss., Methods: This review encompasses both prospective and retrospective approaches, as well as cross-sectional and longitudinal trials conducted on CIs in adults. All studies related to European countries (Austria, Germany, Switzerland, the Netherlands, Sweden, the UK and Poland) were conducted in English and were published between 2012 and June 2023., Results: Nine studies were included in the analysis. The patients' ages ranged from 18 years to over 67 years, with sample sizes ranging from 20 to 100 patients; two of these studies were focused on single-sided deafness in adults. The Markov model was identified as the most commonly utilized analysis method., Conclusions: This review identified a general consensus on CI cost-effectiveness, despite substantial variability among countries in factors such as observation time horizons, cost-effectiveness thresholds, methods of cost collection, discount rates, CI eligibility criteria and country-specific health systems. Generally, CIs yield positive societal benefits for working-age individuals, potentially less for seniors. Early unilateral CI enhances cost-effectiveness, highlighting the importance of prompt candidate identification. A consistent undersupply of CIs relative to the percentage of potential recipients emerged across countries. Therefore, further investigation into subcategories such as single-sided deafness is warranted, along with country-specific cost analyses. Emphasizing the significance of detailed information on health systems and associated costs and benefits is crucial for facilitating comparisons across different settings., (© 2024. The Author(s).)

Purpose: The choice of surgical approach for floor of the mouth (FOM) cancer, particularly for intermediate-stage tumors (cT2-cT3), remains controversial. This study aims to evaluate a method considering mylohyoid muscle (MM) invasion as a determinant for surgical approach selection, utilizing magnetic resonance imaging (MRI) preoperatively and frozen section (FS) analysis intraoperatively., Methods: This observational retrospective cohort study analyzed patients undergoing surgical resection of cT2 and cT3 FOM squamous cell carcinoma (SCC) between January 2013 and June 2023. MM infiltration assessed by preoperative MRI determined the surgical approach: clear infiltration led to compartmental surgery (CS), while doubtful or absent infiltration led to transoral surgery (TOS). Conversion from TOS to CS occurred intraoperatively based on macroscopic evidence or positive FS. Data collected included demographic, clinical, surgical, and pathological variables. Survival analysis was conducted using Kaplan-Meier method., Results: Among 44 patients included, majority had cT2 tumors (59.1%). MM resection was necessary in 22.7% of cases. Overall survival (OS) and progression-free survival (PFS) did not significantly differ between TOS and CS groups. Radiological depth of invasion (rDOI) < 10 mm is correlated with MM preservation in 89% of cases, while rDOI > 10 mm is correlated with MM resection only in 23.8% of cases. Pathological depth of invasion (pDOI) discrepancies were observed in the two groups: in CS group is shown a higher pDOI (> 10 mm) confirmation (90%). Surgical complications and functional outcomes differed between TOS and CS groups., Conclusion: Considering MM invasion for surgical approach selection in cT2-cT3 FOM tumors appears oncologically safe, with better functional outcomes in muscle preservation. Preoperative MRI for MM assessment combined with intraoperative FS analysis provides reliable guidance for surgical decision-making., (© 2024.

Objectives: The aim of this study was to determine the impact of the involvement of the superior pharyngeal constrictor muscle (SPCM) evaluated by magnetic resonance imaging (MRI) on outcome in oropharyngeal squamous cell carcinomas (OPSCCs)., Methods: A retrospective study including consecutive patients with OPSCC treated with curative intent., Results: A total of 82 consecutive patients with OPSCC met inclusion criteria. At multivariate analysis, patients with SPCM infiltration were at significantly higher risk of death (HR: 3.37, CI: 1.21-9.38) and progression (HR: 3.39, CI: 1.38-8.32). In a multivariate model conditioned on HPV status, a significantly higher risk of death and progression was observed by combining both SPCM and HPV status with patients harboring an HPV-negative OPSCC with SPCM infiltration showing the poorest outcome., Conclusion: MRI evidence of SPCM involvement significantly and independently increases the risk of death and progression in subjects with OPSCC. Considering both MRI-assessed SPCM infiltration and HPV status significantly improved risk stratification in these malignancies., (© 2023 The Authors.

Purpose: To investigate the association between time-to-surgery (TTS) and overall survival (OS), disease specific survival (DSS) and quality of life (QoL) in patients with oral squamous cell carcinoma (OSCC)., Materials and Methods: 116 patients with OSCC candidate to surgery were examined. TTS intervals starting from diagnosis (TTS-clinical-based) and from histological reports (TTS-biopsy-based) were calculated. The effects of TTS intervals and prognostic factors on 5-year OS and DSS were explored., Results: In our cohort advanced T-categories OSCCs with TTS < 30 days showed a trend to have higher DSS rate (p = 0.049). Patients with TTS-clinical-based < 30 days showed better postoperative QoL. Positive surgical margins, nodal involvement (pN+), DOI >10 mm, invasive surgery and extra-capsular extension in pN+ were found to be significantly associated with a poor OS and DSS., Conclusions: TTS ≥ 30 days can adversely affect DSS, especially in the advanced T categories. Short TTS intervals resulted associated with a better postoperative QoL., Competing Interests: Declaration of competing interest None., (Copyright © 2023 The Authors. Published by Elsevier Inc.

The cochlear implant (CI) is a widely accepted option in patients with severe to profound hearing loss receiving limited benefit from traditional hearing aids. CI surgery uses a default setting for frequency allocation aiming to reproduce tonotopicity, thus mimicking the normal cochlea. One emerging instrument that may substantially help the surgeon before, during, and after the surgery is a surgical planning software product developed in collaboration by CASCINATION AG (Bern, Switzerland) and MED-EL (Innsbruck Austria). The aim of this narrative review is to present an overview of the main features of this otological planning software, called OTOPLAN ® . The literature was searched on the PubMed and Web of Science databases. The search terms used were "OTOPLAN", "cochlear planning software" "three-dimensional imaging", "3D segmentation", and "cochlear implant" combined into different queries. This strategy yielded 52 publications, and a total of 31 studies were included. The review of the literature revealed that OTOPLAN is a useful tool for otologists and audiologists as it improves preoperative surgical planning both in adults and in children, guides the intraoperative procedure and allows postoperative evaluation of the CI.

Background: The aim of this study was to psychophysically evaluate the prevalence of smell and taste dysfunction 2 years after mildly symptomatic severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection compared to that observed at 1-year follow-up and while considering the background of chemosensory dysfunction in the no-coronavirus disease 2019 (COVID-19) population., Method: This is a prospective case-control study on 93 patients with polymerase chain reaction (PCR)-positive SARS-CoV-2 infection and 93 matched controls. Self-reported olfactory and gustatory dysfunction was assessed by 22-item Sino-Nasal-Outcome Test (SNOT-22), item "Sense of smell or taste." Psychophysical orthonasal and retronasal olfactory function and gustatory performance were estimated using the extended Sniffin' Sticks test battery, 20 powdered tasteless aromas, and taste strips test, respectively. Nasal trigeminal sensitivity was assessed by sniffing a 70% solution of acetic acid., Results: The two psychophysical assessments of chemosensory function took place after a median of 409 days (range, 366-461 days) and 765 days (range, 739-800 days) from the first SARS-CoV-2-positive swab, respectively. At 2-year follow-up, cases exhibited a decrease in the prevalence of olfactory (27.9% vs. 42.0%; absolute difference, -14.0%; 95% confidence interval [CI], -21.8% to -2.6%; p = 0.016) and gustatory dysfunction (14.0% vs. 25.8%; absolute difference, -11.8%; 95% CI, -24.2% to 0.6%; p = 0.098). Subjects with prior COVID-19 were more likely than controls to have an olfactory dysfunction (27.9% vs. 10.8 %; absolute difference, 17.2%; 95% CI, 5.2% to 28.8%) but not gustatory dysfunction (14.0% vs. 9.7%; absolute difference, 4.3%; 95% CI, -5.8% to 14.4% p = 0.496) still 2 years after the infection. Overall, 3.2% of cases were still anosmic 2 years after the infection., Conclusions: Although a proportion of subjects recovered from long-lasting smell/taste dysfunction more than 1 year after COVID-19, cases still exhibited a significant excess of olfactory dysfunction 2 years after SARS-CoV-2 infection when compared to matched controls., (© 2023 ARS-AAOA, LLC.)

The COVID-19 pandemic brought attention to our limited understanding of human olfactory physiology. While the cellular composition of the human olfactory epithelium is similar to that of other vertebrates, its functional properties are largely unknown. We prepared acute slices of human olfactory epithelium from nasal biopsies and used the whole-cell patch-clamp technique to record electrical properties of cells. We measured voltage-gated currents in human olfactory sensory neurons and supporting cells, and action potentials in neurons. Additionally, neuronal inward current and action potentials responses to a phosphodiesterase inhibitor suggested a transduction cascade involving cAMP as a second messenger. Furthermore, responses to odorant mixtures demonstrated that the transduction cascade was intact in this preparation. This study provides the first electrophysiological characterization of olfactory sensory neurons in acute slices of the human olfactory epithelium, paving the way for future research to expand our knowledge of human olfactory physiology., Competing Interests: The authors declare no competing financial interests., (© 2023 The Author(s).)

Background: The prevalence and incidence of oropharyngeal squamous cell carcinomas (OPSCCs) driven by human papillomavirus (HPV) infection are increasing worldwide, being higher in high-income countries. However, data from Italy are scanty. p16 INK4a overexpression is the standard in determining HPV-driven carcinogenesis, but disease prevalence impacts on its positive predictive value., Methods: This is a multicenter retrospective study enrolling 390 consecutive patients aged ≥18 years, diagnosed with pathologically confirmed OPSCC in Northeastern Italy between 2000 and 2022. High-risk HPV-DNA and p16 INK4a status were retrieved from medical records or evaluated in formalin-fixed paraffin-embedded specimens. A tumor was defined as HPV-driven when double positive for high-risk HPV-DNA and p16 INK4a overexpression., Results: Overall, 125 cases (32%) were HPV-driven, with a significant upward temporal trend from 12% in 2000-2006 to 50% in 2019-2022. The prevalence of HPV-driven cancer of the tonsil and base of the tongue increased up to 59%, whereas it remained below 10% in other subsites. Consequently, the p16 INK4a positive predictive value was 89% for the former and 29% for the latter., Conclusions: The prevalence of HPV-driven OPSCC continued to increase, even in the most recent period. When using p16 INK4a overexpression as a surrogate marker of transforming HPV infection, each institution should consider the subsite-specific prevalence rates of HPV-driven OPSCC as these significantly impact on its positive predictive value.

Purpose: New prognostic factors in oral squamous cell carcinoma (OSCC) (tumor-, host-, and environment-related) have been introduced recently to complete those traditionally considered. Among them, tumor volume (TV) could be the most interesting and applicable in clinical practice, considering the routine use of computed tomography in tumor staging. In this retrospective study we aimed to investigate whether a correlation exists among these new prognostic factors and survival outcomes., Meterials and Methods: We collected data about 140 patients affected by OSCC who underwent primary surgery. Prognostic factors were collected and Overall Survival (OS), Disease Specific Survival (DSS) and Disease Free Survival (DFS) were estimated using Kaplan-Meier method; the Log-Rank test (Mantel-Cox) and Cox regression models were applied to investigate predictors of survival., Results: The 5-year OS, DSS and DFS were 73.6 %, 89.2 % and 75.2 % respectively. Nodal metastasis (pN+), relapse and American Society of Anesthesiologists ASA-II were found independent prognostic factors for OS, and significantly associated to worst DSS (p < 0.001). TV significantly correlated with higher relapse occurrence (p = 0.03)., Conclusions: In our experience, lymph-node status, ASA classification and relapse significantly influenced DSS on univariate analysis. TV could represent an interesting additional parameter, since it significantly influenced DFS. However, prospective studies with standardized TV measurements and a greater number of patients are needed to validate this result., Competing Interests: Declaration of competing interest None., (Copyright © 2022 Elsevier Inc.

Introduction: No studies have reported data on 2-year prevalence and recovery rates of self-reported COVID-19-related quantitative and qualitative olfactory and gustatory dysfunction. The aim of the present study was to estimate the 2-year prevalence and recovery rate of self-reported COVID-19-related olfactory and gustatory dysfunction in a cohort of patients with antecedent mild-to-moderate disease., Methods: This is a prospective observational study, measuring the prevalence of altered sense of smell or taste at follow-up and their variation from baseline, on adult patients consecutively assessed at Trieste University Hospital, who tested positive for SARS-CoV-2 RNA by polymerase chain reaction during March 2020., Results: Overall, 174 (68.8%), 53 (20.9%), and 36 (14.2%) of 253 responders reported an altered sense of smell or taste (SNOT-22 >0) at baseline, 12 months, and 24 months, respectively. Among the 174 patients who have complained a COVID-19-associated olfactory or gustatory dysfunction at baseline, 138 (79.3%) reported complete resolution of smell or taste impairment with 17 subjects (9.8%) recovering after more than 1 year after the initial infection, 33 (19.0%) reported a decrease in the severity, and only 3 (1.7%) reported that the symptom was unchanged at the 24-month interview. Twenty subjects (7.9%) complained of at least one qualitative long-term symptom., Conclusion: Two years after the infection, most patients experience a favourable evolution of COVID-19-related olfactory or gustatory dysfunction. A late recovery was observed in 10% of subjects., (© 2022 S. Karger AG, Basel.)

Cystic masses of the lateral neck are mostly benign. However, the incidence of metastatic squamous cell carcinoma (SCC) in cervical cystic masses initially diagnosed as benign is quite high in patients older than 40 years. The aim of this study was to compare the diagnostic accuracy of preoperative cytology and intraoperative frozen section (FS) in detecting malignancy in cystic masses of the neck. We reviewed 61 patients who underwent preoperative ultrasound-guided fine-needle aspiration cytology (FNAC) and neck biopsy of a cystic neck mass, and analysed the concordance between FNAC and intraoperative FS with respect to definitive histology. HPV status was also tested. Of 49 eligible cases, the accuracy of preoperative FNAC was 70.5% (weighted kappa 0.53), meaning moderate agreement between cytology and final diagnosis. Intraoperative FS consultations detected 16 cases of SCC metastasis while the remaining 33 cases were negative for SCC, showing perfect agreement with histology. Since FS results were useful in evaluating cystic neck masses, despite a moderate accuracy of cytology, we suggest intraoperative FS analysis for all cystic neck masses. This technique can allow us to switch to therapeutic neck dissection, multiple upper aerodigestive tract biopsies, tongue base mucosectomy, and bilateral tonsillectomy in the same surgical setting., Competing Interests: Conflict of interest We have no conflicts of interest., (Copyright © 2022 The British Association of Oral and Maxillofacial Surgeons.

Background: The aim of this study was to estimate the prevalence of self-reported chemosensory dysfunction in a study cohort of subjects who developed a mild-to-moderate coronavirus disease 2019 (COVID-19) in the period from January 17, 2022, to February 4, 2022 (Omicron proxy period) and compared that with a historical series of patients testing positive for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection between March and April, 2020 (comparator period)., Methods: Prospective study based on the 22-item Sino-Nasal Outcome Tool (SNOT-22), item "sense of smell or taste" and additional outcomes., Results: Patients' characteristics and clinical presentations of COVID-19 were evaluated and compared in 779 patients, 338 of the study cohort and 441 of the historical series. The prevalence of self-reported chemosensory dysfunction during the proxy Omicron period (32.5%; 95% confidence interval [CI], 27.6-37.8) was significantly lower from that during the comparator period (66.9%; 95% CI, 62.3-71.3) (p < 0.001). Nearly one-quarter of patients (24.6%; 95% CI, 20.1-29.5) reported an altered sense of smell during the proxy Omicron period compared to 62.6% (95% CI, 57.9-67.1) during the comparator period (p < 0.001). Similarly, the prevalence of an altered sense of taste dropped to 26.9% (95% CI, 22.3-32.0) during the proxy Omicron period from 57.4% (95% CI, 52.6-62.0) during the comparator period (p < 0.001). The severity of chemosensory dysfunction was lower in the proxy Omicron period compared to the comparator period (p < 0.001)., Conclusion: The prevalence and the severity of COVID-19-associated smell and taste dysfunction has dropped significantly with the advent of the Omicron variant but it still remains above 30%., (© 2022 ARS-AAOA, LLC.)

Background: Immune checkpoint inhibitors (ICI) are approved for treatment of recurrent or metastatic oropharyngeal head and neck squamous cell carcinoma in the first- and second-line settings. However, only 15-20% of patients benefit from this treatment, a feature increasingly ascribed to the peculiar characteristics of the tumor immune microenvironment (TIME)., Methods: Immune-related gene expression profiling (GEP) and multiplex immunofluorescence (mIF) including spatial proximity analysis, were used to characterize the TIME of 39 treatment-naïve oropharyngeal squamous cell carcinomas (OPSCC) and the corresponding lymph node metastases. GEP and mIF results were correlated with disease-free survival (DFS). HPV-positive tumors disclosed a stronger activation of several immune signalling pathways, as well as a higher expression of genes related to total tumor-infiltrating lymphocytes, CD8 T cells, cytotoxic cells and exhausted CD8 cells, than HPV-negative patients. Accordingly, mIF revealed that HPV-positive lesions were heavily infiltrated as compared to HPV-negative counterparts, with a higher density of T cells and checkpoint molecules. CD8+ T cells appeared in closer proximity to tumor cells, CD163+ macrophages and FoxP3+ cells in HPV-positive primary tumors, and related metastases. In HPV-positive lesions, PD-L1 expression was increased as compared to HPV-negative samples, and PD-L1+ tumor cells and macrophages were closer to PD-1+ cytotoxic T lymphocytes. Considering the whole cohort, a positive correlation was observed between DFS and higher levels of activating immune signatures and T cell responses, higher density of PD-1+ T cells and their closer proximity to tumor cells or PD-L1+ macrophages. HPV-positive patients with higher infiltration of T cells and macrophages had a longer DFS, while CD163+ macrophages had a negative role in prognosis of HPV-negative patients., Conclusions: Our results suggest that checkpoint expression may reflect an ongoing antitumor immune response. Thus, these observations provide the rationale for the incorporation of ICI in the loco-regional therapy strategies for patients with heavily infiltrated treatment-naïve OPSCC, and for the combination of ICI with tumor-specific T cell response inducers or TAM modulators for the "cold" OPSCC counterparts., (© 2022.

Background/aims: Quantitative and qualitative alterations in the sense of smell are well established symptoms of COVID-19. Some reports have shown that non-neuronal supporting (also named sustentacular) cells of the human olfactory epithelium co-express ACE2 and TMPRSS2 necessary for SARS-CoV-2 infection. In COVID-19, syncytia were found in many tissues but were not investigated in the olfactory epithelium. Some studies have shown that syncytia in some tissues are formed when SARS-CoV-2 Spike expressed at the surface of an infected cell binds to ACE2 on another cell, followed by activation of the scramblase TMEM16F (also named ANO6) which exposes phosphatidylserine to the external side of the membrane. Furthermore, niclosamide, an approved antihelminthic drug, inhibits Spike-induced syncytia by blocking TMEM16F activity. The aim of this study was to investigate if proteins involved in Spike-induced syncytia formation, i.e., ACE2 and TMEM16F, are expressed in the human olfactory epithelium., Methods: We analysed a publicly available single-cell RNA-seq dataset from human nasal epithelium and performed immunohistochemistry in human nasal tissues from biopsies., Results: We found that ACE2 and TMEM16F are co-expressed both at RNA and protein levels in non-neuronal supporting cells of the human olfactory epithelium., Conclusion: Our results provide the first evidence that TMEM16F is expressed in human olfactory supporting cells and indicate that syncytia formation, that could be blocked by niclosamide, is one of the pathogenic mechanisms worth investigating in COVID-19 smell loss., Competing Interests: The authors declare they have no conflicts of interest., (© Copyright by the Author(s).

Background: Inflammatory blood markers have been associated with oncological outcomes in several cancers, but evidence for head and neck squamous cell carcinoma (HNSCC) is scanty. Therefore, this study aims at investigating the association between five different inflammatory blood markers and several oncological outcomes., Methods: This multi-centre retrospective analysis included 925 consecutive patients with primary HPV-negative HNSCC (median age: 68 years) diagnosed between April 2004 and June 2018, whose pre-treatment blood parameters were available. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), systemic inflammatory marker (SIM), and systemic immune-inflammation index (SII) were calculated; their associations with local, regional, and distant failure, disease-free survival (DFS), and overall survival (OS) was calculated., Results: The median follow-up was 53 months. All five indexes were significantly associated with OS; the highest accuracy in predicting patients' survival was found for SIM (10-year OS = 53.2% for SIM < 1.40 and 40.9% for SIM ≥ 2.46; c-index = 0.569) and LMR (10-year OS = 60.4% for LMR ≥ 3.76 and 40.5% for LMR < 2.92; c-index = 0.568). While LMR showed the strongest association with local failure (HR = 2.16; 95% CI:1.22-3.84), PLR showed the strongest association with regional (HR = 1.98; 95% CI:1.24-3.15) and distant failure (HR = 1.67; 95% CI:1.08-2.58)., Conclusion: Different inflammatory blood markers may be useful to identify patients at risk of local, regional, or distant recurrences who may benefit from treatment intensification or intensive surveillance programs., (© 2022.

Background: The COVID-19 pandemic has made wearing face masks a common habit in public places. Several reports have underlined the increased difficulties encountered by deaf people in speech comprehension, resulting in a higher risk of social isolation and psychological distress., Purpose: To address the detrimental effect of different types of face masks on speech perception, according to the listener hearing level and background noise., Research Design: Quasi-experimental cross-sectional study., Study Sample: Thirty patients were assessed: 16 with normal hearing [NH], and 14 hearing-impaired [HI] with moderate hearing loss., Data Collection and Analysis: A speech perception test (TAUV) was administered by an operator trained to speak at 65 dB, without a face mask, with a surgical mask, and with a KN95/FFP2 face mask, in a quiet and in a noisy environment (cocktail party noise, 55 dB). The Hearing Handicap Index for Adults (HHI-A) was administered twice, asking subjects to complete it for the period before and after the pandemic outburst. A 2-way repeated-measure analysis of variance was performed., Results: The NH group showed a significant difference between the no-mask and the KN95/FFP2-mask condition in noise ( p  = 0.01). The HI group showed significant differences for surgical or KN95/FFP2 mask compared with no-mask, and for KN95/FFP2 compared with surgical mask, in quiet and in noise ( p  < 0.001). An increase in HHI-A scores was recorded for the HI patients ( p  < 0.001)., Conclusion: Face masks have a detrimental effect on speech perception especially for HI patients, potentially worsening their hearing-related quality of life., Competing Interests: None declared., (American Academy of Audiology.

Purpose: The aim of the present study was to estimate the 1 year prevalence and recovery rate of self-reported chemosensory dysfunction in a series of subjects with previous mild-to-moderate symptomatic COVID-19., Methods: Prospective study based on the SNOT-22, item "sense of smell or taste" and additional outcomes., Results: 268/315 patients (85.1%) completing the survey at baseline also completed the follow-up interview. The 12 months prevalence of self-reported COVID-19 associated chemosensory dysfunction was 21.3% (95% CI 16.5-26.7%). Of the 187 patients who complained of COVID-19 associated chemosensory dysfunction at baseline, 130 (69.5%; 95% CI 62.4-76.0%) reported complete resolution of smell or taste impairment, 41 (21.9%) reported a decrease in the severity, and 16 (8.6%) reported the symptom was unchanged or worse 1 year after onset. The risk of persistence was higher for patients reporting a baseline SNOT-22 score ≥ 4 (OR = 3.32; 95% CI 1.32-8.36) as well as for those requiring ≥ 22 days for a negative swab (OR = 2.18; 95% CI 1.12-4.27)., Conclusion: A substantial proportion of patients with previous mild-to-moderate symptomatic COVID-19 characterized by new onset of chemosensory dysfunction still complained on altered sense of smell or taste 1 year after the onset., (© 2021.

Objectives: Nodal metastasis is an important prognosticator in primary parotid cancers. The management of the clinically node-negative neck is an area lacking consensus. This study investigates the occult nodal metastasis rate, and prognostic indicators in primary parotid cancers., Materials and Methods: We performed a multicentre retrospective case note review of patients diagnosed and treated surgically with curative intent between 1997 and 2020. Demographic, clinic-pathological and follow-up data was recorded., Results: After exclusions, 334 patients were included for analysis, with a median follow-up of 48 months. The overall rate of occult lymph node metastasis amongst patients undergoing elective neck dissection was 22.4%, with older age, high-grade and more advanced primary tumours being associated with higher rates. On multivariable analysis, age ≥ 60 years (HR = 2.69, p = 0.004), high-grade tumours (HR = 2.70, p = 0.005) and advanced primary tumours (pT3-4, HR = 2.06, p = 0.038) were associated with worse overall survival. Occult nodal metastasis on final pathology was associated with a close-to-significant reduction in regional recurrence free survival (HR = 3.18, p = 0.076)., Conclusion: This large series confirms the significant occult lymph node metastasis rate in primary parotid cancer, and demonstrates the importance of primary histology, tumour grade and stage in predicting survival outcome. This data supports the use of elective neck dissection in patients with high-risk tumours., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Objective: To date, no useful prognostic biomarker exists for patients with oral squamous cell carcinoma (OCSCC), a tumour with uncertain biological behaviour and subsequent unpredictable clinical course. We aim to investigate the prognostic significance of two recurrent somatic mutations (-124 C>T and -146 C>T) within the promoter of telomerase reverse transcriptase ( TERT ) gene and the impact of TERT single nucleotide polymorphism (SNP) rs2853669 in patients surgically treated for OCSCC., Methods: The genetic frequencies of rs2853669, -124 C>T and -146 C>T as well as the telomere length were investigated in 144 tumours and 57 normal adjacent mucosal (AM) specimens from OCSCC patients., Results: Forty-five tumours harboured TERT promoter mutations (31.3%), with -124 C>T and -146 C>T accounting for 64.4% and 35.6% of the alterations respectively. Patients with -124 C>T TERT promoter mutated tumours had the shortest telomeres in the AM (p=0.016) and showed higher risk of local recurrence (hazard ratio [HR]:2.75, p=0.0143), death (HR:2.71, p=0.0079) and disease progression (HR:2.71, p=0.0024) with the effect being potentiated by the co-occurrence of T/T genotype of rs2853669., Conclusion: -124 C>T TERT promoter mutation as well as the T/T genotype of the rs2853669 SNP are attractive independent prognostic biomarkers in patients surgically treated for OCSCC, with the coexistence of these genetic variants showing a synergistic impact on the aggressiveness of the disease., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Giunco, Boscolo-Rizzo, Rampazzo, Tirelli, Alessandrini, Di Carlo, Rossi, Nicolai, Menegaldo, Carraro, Tofanelli, Bandolin, Spinato, Emanuelli, Mantovani, Stellin, Bussani, Dei Tos, Guido, Morello, Fussey, Esposito, Polesel and De Rossi.)

Introduction: After surgery for oral cavity cancer, superficial surgical defects are usually covered with a skin graft that can be harvested with different thicknesses depending on the reconstructive need. Despite its popularity and efficacy, this solution has the disadvantage of excessive harvesting times and scarring of the donor site. Other surgeons have proposed the use of bovine pericardium as a reconstructive solution. Its use in otorhinolaryngology especially after oral cavity surgery has never been reported., Objective: The aim of this manuscript is to present our preliminary experience with the use of a collagen membrane obtained from bovine pericardium in the reconstruction of small and superficial defects after transoral resection of oral cavity tumors., Methods: A bovine collagen membrane was used to cover surgical defects in 19 consecutive patients undergoing transoral resection of small/superficial oral cancers. Photographs were obtained in the postoperative period to follow the healing process. We analyzed the pro and cons of this tool, recorded data on postoperative chewing-, speech- and taste-related quality of life, and tested the most appropriate settings providing the best reconstructive result., Results: The bovine collagen membrane allowed us to cover surgical defects of varying size in different oral sites. Shaping and placement proved to be simple. The membrane facilitated physiologic tissue repair: after one month it was completely absorbed and replaced by the patient's own mucosa. No adverse features were observed in the cohort., Conclusion: A bovine collagen membrane can represent a fast and easy solution in cases of split-thickness defect. Unlike a skin graft, it is not associated with donor site morbidity and allows the patient's own mucosa to be restored with a more physiological result., (Copyright © 2020 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Purpose: The aim of this study is to evaluate the prognostic value of pre-treatment advanced lung cancer inflammation index (ALI) in patients with HPV-negative HNSCC undergoing up-front surgical treatment., Methods: The present multi-centre, retrospective study was performed in a consecutive cohort of patients who underwent upfront surgery with or without adjuvant (chemo)-radiotherapy for head and neck squamous cell carcinoma (HNSCC). Patients were stratified by ALI, and survival outcomes were compared between groups. In addition, the prognostic value of ALI was compared with two other indices, the prognostic nutritional index (PNI) and systemic inflammatory index (SIM)., Results: Two hundred twenty-three patients met the inclusion criteria (151 male and 72 female). Overall and progression-free survival were significantly predicted by ALI < 20.4 (HR 3.23, CI 1.51-6.90 for PFS and HR 3.41, CI 1.47-7.91 for OS). Similarly, PNI < 40.5 (HR = 2.43, 95% CI: 1.31-4.51 for PFS and HR = 2.40, 95% CI: 1.19-4.82 for OS) and SIM > 2.5 (HR = 2.51, 95% CI: 1.23-5.10 for PFS and HR = 2.60, 95% CI: 1.19-5.67 for OS) were found to be significant predictors. Among the three indices, ALI < 20.4 identified the patients with the worst 5-year outcomes. Moreover, patients with a combination of low PNI and low ALI resulted to be a better predictor of progression (HR = 5.26, 95% CI: 2.01-13.73) and death (HR = 5.68, 95% CI: 1.92-16.79) than low ALI and low PNI considered alone., Conclusions: Our results support the use of pre-treatment ALI, an easily measurable inflammatory/nutritional index, in daily clinical practice to improve prognostic stratification in surgically treated HPV-negative HNSCC.
