Design of a study to investigate the mechanisms of obstructive sleep apnoea by means of drug-induced sleep endoscopy
Background Obstructive sleep apnoea (OSA) is an independent risk factor of hypertension and cardiovascular diseases. Recurrent episodes of upper airways collapse during sleep causing blood oxygen desaturation, hypercapnia, and micro-arousals, are known to activate the sympathetic nervous system (SNS). However, whether changes in the renin-angiotensin-aldosterone system and endothelial activation also occur remains contentious. Methods Based on routine use of drug-induced sleep endoscopy (DISE) for the work-up of OSA patients in our centre, we designed a prospective study to investigate the haemodynamic and humoral changes occurring during the apnoeic episodes reproduced in vivo in the course of DISE. Specifically, plasma aldosterone concentration and renin activity, C-terminal fragment of proendothelin-1, as a marker of endothelial damage, and free plasma catecholamines, will be measured at fixed times during DISE. The activity of catechol-O-methyltransferase (COMT), a key catecholamine-inactivating enzyme that has been scantly investigated thus far owing to the lack of commercially available kits, will be also determined by a newly developed high performance liquid chromatography method, which is herein described. Results and conclusions The aim of this study is to provide novel information on the haemodynamic, hormonal, and SNS changes, and also on COMT activity modification concomitantly occurring during apnoea, thus contributing substantively to the understanding of the pathophysiology of OSA
Advanced lung cancer inflammation index and its prognostic value in HPV-negative head and neck squamous cell carcinoma: a multicentre study
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 1.51â6.90 for PFS and HR 3.41, CI 1.47â7.91 for OS). Similarly, PNI < 40.5 (HR = 2.43, 95% CI: 1.31â4.51 for PFS and HR = 2.40, 95% CI: 1.19â4.82 for OS) and SIM > 2.5 (HR = 2.51, 95% CI: 1.23â5.10 for PFS and HR = 2.60, 95% CI: 1.19â5.67 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: 2.01â13.73) and death (HR = 5.68, 95% CI: 1.92â16.79) 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
Olfactory Dysfunction in COVID-19 Patients Who Do Not Report Olfactory Symptoms: A Pilot Study with Some Suggestions for Dentists
Background: Smell and taste dysfunction are frequently reported by SARS-CoV-2 positive patients. The degree of olfactory and gustatory dysfunction varies from a very mild reduction to their complete loss. Several studies have been performed to determine their prevalence in COVID-19 patients, mostly using subjective measurement methods. The literature lacks long-term studies regarding duration and recovery. Methods: We assessed olfactory performance, using the Sniffinâ Sticks olfactory test, in a group of patients who had not reported olfactory dysfunction, around 131 days after their COVID-19 diagnosis. Results: 11 out of 20 subjects showed no olfactory reduction (65%), while 9 subjects showed reduced TDI score (45%). A total of 13 subjects (65%) scored above the cutoff point for Threshold, 16 subjects (80%) scored above the cutoff point for discrimination and 13 subjects (65%) scored above the cutoff point for identification. Conclusion: Objective measurement methods of olfactory performance show a higher prevalence of olfactory reduction compared to patientsâ self-reported questionnaires. Olfactory dysfunction can last even months after its onset and because of its high prevalence, it could be a screening symptom for suspect COVID-19 case

Può essere classificato come ipomotilitĂ o fissitĂ ed è attribuibile a vari meccanismi legatiallâestensione della neoplasia verso la porzione posteriore dello spazio paraglottico inferiore. Tale estensionecomporta un peggioramento della prognosi nei pazienti sottoposti a chirurgia parziale (OPHL), mentre alcunistudi sembrano indicare che la prognosi dei pazienti trattati con laringectomia totale non risulta influenzatadallo stesso pattern di crescita. Lo scopo dello studio è identificare il miglior trattamento nei pazienti affetti dacarcinoma laringeo con compromissione della motilitĂ aritenoidea.Materiali e metodi: Ă stato condotto uno studio retrospettivo multicentrico, includendo pazienti affetti dacarcinoma laringeo con compromissione della motilitĂ aritenoidea. In questa analisi preliminare sono stativalutati lâoverall survival (OS) e la severe laryngoesophageal dysfunction-free survival (SLEDFS). I dati sonostati analizzati mediante unâanalisi univariata con il metodo di Kaplan-Meier e il log-rank test.Risultati: Lo studio ha incluso 391 pazienti, con etĂ media di 64 anni. 25 (6,4%) tumori sono stati classificaticome T2, 225 (57,5%) come T3 e 139 (35,5%) come T4. Sulla base della valutazione endoscopicapreoperatoria 209 pazienti si presentavano con ipomotilitĂ aritenoidea e 182 con fissitĂ . I trattamentieffettuati hanno compreso: laringectomia totale (n=179, 45,8%), OPHL di tipo II (n=110, 28,1%), OPHL ditipo III (n=32, 8,2%) o (chemio)radioterapia preceduta o meno da chemioterapia neoadiuvante (n=70,17,9%). Il trattamento adiuvante è stato eseguito in 141 casi (44,2%). LâOS a 5 anni è risultata del 71,8%. Ilgrado di ipomotilitĂ aritenoidea è risultato significativamente associato allâOS a 5 anni (fissitĂ aritenoidea61,6%, ipomotilitĂ 79,2%; p=0,007). Nei pazienti trattati con preservazione dâorgano lâOS a 5 anni è risultatadellâ81,0%, rispetto al 57,7% dopo laringectomia totale (p=0,0004).Nei pazienti con preservazione dâorgano la SLEDFS a 5 anni è risultata dellâ85,4%. LâOPHL di tipo II èrisultata associata a SLEDFS a 5 anni superiore (91,6%) rispetto a OPHL di tipo III (73,9%) e trattamenti nonchirurgici (79,9%) (p=0,042). La radioterapia esclusiva è risultata associata ad una riduzione della OS(p<0,0001) e della SLEDFS (p=0,071).Conclusioni: Il deficit di motilitĂ aritenoidea ha dimostrato un ruolo prognostico negativo nei pazienti affettida carcinoma laringeo. I trattamenti di preservazione dâorgano non hanno comportato un peggioramentodella prognosi rispetto alla laringectomia totale. La funzione laringea post-trattamento è risultatasoddisfacente, specialmente nei pazienti sottoposti a OPHL di tipo II. I pazienti trattati con radioterapiaesclusiva hanno presentato risultati oncologici e funzionali peggiori rispetto alle altre strategie dipreservazione dâorgano.</p
HCV infection and the risk of head and neck cancer: A meta-analysis
Recent evidence has consistently suggested a role for HCV in the etiology of head and neck squamous cell carcinoma (HNSCC), but the conclusions of these studies have often been limited by small sample size. Therefore, a meta-analysis was performed to summarize present evidence on the association between HCV infection and HNSCC. After screening citations from literature search, eight observational studies investigating the association between HCV and cancer(s) of either oral cavity, oropharynx, hypopharynx or larynx were included. For each cancer site, risk ratios from individual studies were displayed in forest plots; pooled risk ratios (RR) and corresponding confidence intervals (CI) were calculated. A significant association was found between HCV infection and cancers of the oral cavity (RRÂ =Â 2.13; 95%: 1.61-2.83), oropharynx (RRÂ =Â 1.81; 95% CI: 1.21-2.72), and larynx (RRÂ =Â 2.57; 95% CI: 1.11-5.94). A similar picture emerged for hypopharyngeal cancer, though this result did not fully reach statistical significance because of the small number of available studies (RRÂ =Â 2.15; 95% CI: 0.73-6.31). These findings remained similar after exclusion of patients with HIV co-infection. Our results highlighted the importance of surveillance of the upper aerodigestive tract in patients with known chronic HCV infections in order to enable HNSCC early diagnosis. In addition, they could be a reminder of the possibility of undiagnosed HCV infection to the clinicians treating HNSCC

none10The aim of the present study was to develop and validate the CoronaVirus-Disease-2019 (COVID-19) Questionnaire (COVID-Q), a novel symptom questionnaire specific for COVID-19 patients, to provide a comprehensive evaluation which may be helpful for physicians, and evaluate questionnaire's performance in identifying subjects at higher risk of testing positive.noneSpinato, Giacomo; Fabbris, Cristoforo; Conte, Federica; Menegaldo, Anna; Franz, Leonardo; Gaudioso, Piergiorgio; Cinetto, Francesco; Agostini, Carlo; Costantini, Giulio; Boscolo-Rizzo, PaoloSpinato, Giacomo; Fabbris, Cristoforo; Conte, Federica; Menegaldo, Anna; Franz, Leonardo; Gaudioso, Piergiorgio; Cinetto, Francesco; Agostini, Carlo; Costantini, Giulio; Boscolo-Rizzo, Paol
Risk management during COVID-19: safety procedures for otolaryngologists
The pandemic caused by SARS-CoV2 has stressed health care systems worldwide. The high volume of patients, combined with an increased need for intensive care and potential transmission, has forced reorganization of hospitals and care delivery models. In this article, are presented approaches to minimize risk to Otolaryngologists during their patients infected with COVID-19 care. We performed a narrative literature review among PubMed, Scopus and Web of Science electronic databases, searching for studies on SARS-CoV2 and Risk Management. Standard operating procedures have been adapted both for facilities and for health care workers, including the development of well-defined and segregated patient care areas for treating those affected by COVID-19. Personal protective equipment (PPEs) availability and adequate healthcare providers training on their use should be ensured. Preventive measures are especially important in Otolaryngology-Head and Neck Surgery, as the exposure to saliva suspensions, droplets and aerosols are increased in the upper aero-digestive tract routine examination. Morever, the frequent invasive procedures, such as laryngoscopy, intubation or tracheotomy placement and care, represent a high risk of contracting COVID-19
Olfactory and taste dysfunction among mild-to-moderate symptomatic COVID-19 positive health care workers: An international survey
OBJECTIVE: To determine the prevalence of olfactory and taste dysfunction (OD; TD) among COVIDâ19 positive health care workers (HCWs), their associated risk factors and prognosis.
METHODS:
Between May and June 2020, a longitudinal multicenter study was conducted on symptomatic COVIDâ19 PCR confirmed HCWs (COVIDâ19 positive) in London and Padua.
RESULTS:
Hundred and fourteen COVIDâ19 positive HCWs were surveyed with a response rate of 70.6% over a median followâup period of 52âdays. UK prevalence of OD and TD was 73.1% and 69.2%, respectively. There was a male to female ratio of 1:3 with 81.6% being white, 43.7% being nurses/health care assistants (HCAs), and 39.3% being doctors. In addition, 53.2% of them worked on COVIDâ19 wards. Complete recovery was reported in 31.8% for OD and 47.1% for TD with a 52âdays followâup. The job role of doctors and nurses negatively influenced smell (P =â.04 and P =â.02) and taste recovery (P =â.02 and P =â.01). Ethnicity (being white) showed to positively influence only taste recovery (P =â.04). Sex (being female) negatively influenced OD and TD recovery only in Paduan HCWs (P =â.02 and P =â.011, respectively). Working on a COVIDâ19 ward did not influence prognosis.
CONCLUSIONS: The prevalence of OD and TD was considerably higher in HCWs. The prognosis for OD and TD recovery was worse for nurses/HCAs and doctors but working on a COVIDâ19 ward did not influence prognosis. Sixtyâeight percent of surveyed HCWs at 52âdays continued to experience OD or TD requiring additional future medical management capacity.
