Effectiveness of dupilumab versus endoscopic sinus surgery for the treatment of type-2 chronic rhinosinusitis with nasal polyps: a preliminary report.

PURPOSE: Historically managed with intranasal corticosteroids (INCS) and endoscopic sinus surgery (ESS), type-2 Chronic RhinoSinusitis with Nasal Polyps (CRSwNP) treatment was revolutionized by the introduction of dupilumab but universally accepted guidelines are still lacking. METHODS: Patients treated at our University Hospital for type-2 CRSwNP were enrolled. Demographic data were collected, as well as laboratory (eosinophils, total IgE), endoscopic [nasal polyps score (NPS), modified Lund-Kennedy score (mLKS)], radiological [Lund-Mackay score (LMS) at CT scan], SNOT-22, and olfactory [Sniffin' Sticks identification test (SSIT)] features. Patients were treated with dupilumab or ESS and re-evaluated after 3 and 12 months. RESULTS: At 3 and 12 months, patients undergoing ESS achieved a higher reduction of NPS and mLKS, while patients receiving dupilumab experienced a higher improvement at SNOT-22 and SSIT with a greater positive variation in the prevalence of anosmia (- 57.7% vs - 42.9%) and normosmia (+ 37.8 vs + 28.5%). Mean mLKS and LMS were quite similar. Results were independent of clinical features known to contribute to CRSwNP severity, except for patients with ≥ 2 prior ESS who had a significantly lower smell improvement. CONCLUSION: ESS and dupilumab were effective at reducing CRSwNP inflammatory burning. CRSwNP smell impairment cannot be attributed only to olfactory cleft obstruction and other mechanisms may be involved. Dupilumab acts systemically with poor correlation with NPS. As of today, dupilumab appears to be more suitable for elderly patients with anesthesiological contraindications and/or several previous surgeries, while ESS may represent the first-line choice in surgery-naive patients.

Endoscopy-assisted transoral approach for parapharyngeal space tumors: Our experience and a systematic review of the literature.

Background: Several approaches have been described for the excision of parapharyngeal space tumors (PPSTs). Advances in endoscopy gave a further stimulus to the use of the transoral route. Aims: We present our experience with the endoscopy-assisted transoral approach (EATA) in this regard and a review of the most recent literature about EATA for PPSTs excision. Materials and Methods: We retrospectively analyzed our experience and systematically reviewed the literature about the outcomes of this technique. Results: Seven PPSTs were completely excised, with three of them requiring a combined transcervical approach. Only one case of postoperative wound dehiscence was registered, and the mean length of stay was 3.9 days. Final histopathological examination confirmed the results obtained with preoperative fine-needle aspiration biopsy in all cases and no recurrences were apparent after a mean follow-up of 28.1 months. Discussion: Magnetic resonance imaging, the modified Mallampati score and the 8 Ts criteria are useful instruments for the choice of the most appropriate surgical approach. Conclusion: In light of our experience and following other published series in the literature, we believe that EATA may represent a safe and effective approach for the treatment of the majority of PPSTs.

Low levels of miR-34c in nasal washings as a candidate marker of aggressive disease in wood and leather exposed workers with sinonasal intestinal-type adenocarcinomas (ITACs).

INTRODUCTION: Sinonasal intestinal-type adenocarcinomas (ITACs) are rare and aggressive tumors, closely related to professional exposure to wood dusts or leather. Here we explored the role of non-coding RNAs controlling MUC2 in liquid biopsies and tumors from ITAC patients with the aim of identifying biomarkers and molecular mechanisms to improve early diagnosis, prognosis, and therapeutic approaches for this rare cancer. METHODS: MiR-34c-3p, lncRNA AF147447 and MUC2 were measured in tumors and normal mucosa, in nasal washings (NW) from the affected and non-affected nostril and in plasma from 17 ITAC patients. The Apparent Diffusion Coefficient (ADC) was also evaluated by Magnetic Resonance Imaging. RESULTS: MiR-34c was higher in ITACs compared to the corresponding normal mucosa (p = 0.021). Differentiated tumors exhibited higher miR-34c levels (p = 0.025) and lower ADC values (p<0.001) compared to mucinous ones and these parameters were also inversely correlated (r = 0.87; p = 0.001). High MUC2 tumor expression was associated with orbital extension (p = 0.010). Low miR-34c levels in NW were associated with orbital (p = 0.009) and intracranial (p = 0.031) extension and with advanced TNM stage (p = 0.054). Functional analysis identified Wnt, Focal adhesion, MAPK and inflammatory signalings among the pathways most enriched in mir-34c targets. DISCUSSION: Our results suggest measuring miR-34c in NW as a biomarker for early diagnosis and monitoring of ITAC patients and for the surveillance of wood and leather exposed workers. Further research on the involvement of miR-34c regulated pathways in ITAC tumorigenesis may also allow the development of new therapeutic approaches for this rare cancer.

The impact of the COVID-19 pandemic on the quality of life of head and neck cancer survivors.

BACKGROUND: Head and neck cancer (HNC) survivors are particularly vulnerable to the deleterious consequences of lockdown and social distancing. The psychosocial effects of the COVID-19 pandemic on this group are still unknown, and we want to explore how their quality of life (QoL) has changed in this unique situation. MATERIALS AND METHODS: An online survey, composed of pandemic-specific items, plus the EORTC QLQ-C30, was administered to a cohort of HNC survivors. Using previously published reference values as a control group, we have evaluated the impact of the pandemic on their QoL. We have also explored the differences between those who had received a total laryngectomy (LP, laryngectomized population) vs other HNC patients, in order to assess the role of tracheostomy in this regard. RESULTS: One hundred and twenty-one HNC patients completed the survey. The scores of the physical (80.5 vs 85, p = 0.028), role (78 vs 84, p = 0.030), and emotional functioning (76 vs 81, p = 0.041) were significantly different in the two groups, with worse functioning in our patients. Comparing LP with the other HNC patients, social (76.6 vs 88.9, p = 0.008) and physical functioning (75.5 vs 86.1, p = 0.006) were significantly worse in the former group. LP also reported a greater perception that others are afraid to be close to them (1.67 vs 1.32, p = 0.020). No differences were found between LP with and without voice prosthesis. CONCLUSIONS: Our results show how HNC patients are at high risk for a worsening in QoL because of the ongoing COVID-19 global pandemic.

Epidemiological analysis of a COVID-19 outbreak associated with an infected surgeon.

Control of the novel COronaVIrus Disease-2019 (COVID-19) in a hospital setting is a priority. A COVID-19-infected surgeon performed surgical activities before being tested. An exposure risk classification was applied to the identified exposed subjects and high- and medium-risk contacts underwent active symptom monitoring for 14 days at home. All healthcare professionals (HCPs) were tested for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) at the end of the quarantine and serological tests were performed. Three household contacts and 20 HCPs were identified as high- or medium-risk contacts and underwent a 14-day quarantine. Fourteen HCPs and 19 patients were instead classified as low risk. All the contacts remained asymptomatic and all HCPs tested negative for SARS-CoV-2. About 25-28 days after their last exposure, HCPs underwent serological testing and two of them had positive IgM but negative confirmatory swabs. In a low COVID-19 burden area, the in-hospital transmission of SARS-CoV-2 from an infectious doctor did not occur and, despite multiple and frequent contacts, a hospital outbreak was avoided. This may be linked to the adoption of specific recommendations and to the use of standard personal protective equipment by HCPs.

A New Solution for Routine Endoscopic Aerosol-Generating Procedures (AGPs) in the COVID-19 Pandemic.

INTRODUCTION: There is urgent need to find a swift and cheap way to safely perform routine endoscopic procedures during the otolaryngological and anesthesiological practice. We want to share our experience of a novel device, inspired by the pediatric head box experience. MATERIALS AND METHODS: Five otolaryngologists and four anesthesiologists were asked to visualize the glottic plane by using the device. A total of 15 attempts was allowed to reach the vocal folds within 60 seconds after entering the box. Student's t-test for unpaired samples was used to compare groups. RESULTS: Transnasal laryngoscopy through our endobox could be successfully performed by all the physicians involved and the mean number of attempts before visualizing and passing the glottis for the first time was 2.8 (range 1-5) in the otolaryngologists' group versus 3.2 (range 1-6) in the anesthesiologists' group (P=0.583). Out of the 15 attempts, the group of otolaryngologists reached the glottis 10.2 times, on average, against 9.7 in the other group (P=0.692). CONCLUSIONS: Our endobox seems a practical and feasible strategy to control droplets diffusion during standard ear, nose, and throat and anesthesiological practice.

The clinical consequences of the COVID-19 lockdown: A report from an Italian referral ENT department.

Objectives: To evaluate the clinical effects of health care reorganization because of COVID-19, in a non-red zone Italian referral department of Otorhinolaryngology. Materials and Methods: We retrospectively reviewed the statistics of admissions to the Emergency Department (ED) of the Careggi University Hospital, Florence, from January 1, 2020, to May 17, 2020. Data regarding elective and urgent head and neck disorders were reviewed and the most challenging cases were discussed. Results: During the lockdown period, outpatient otolaryngological consultations and elective procedures decreased by 78% and 75% respectively, while emergency/urgency surgery increased by 128%. The five most emblematic clinical cases were thoroughly analyzed. Conclusion: Our analysis shows how the profound rearrangement of clinical and surgical activities, along with the citizens' fear to seek medical care has probably exacerbated the management of many routine head and neck conditions. Level of Evidence: 4.
