Prognostic Effect of Patterns of Local Extension and Satellitosis in cT3 Squamous Cell Carcinoma of the Oral Tongue: A Prospective Observational Study.

Introduction: The anatomy of the tongue is three-dimensionally complex and is thought to play a central role in the local growth of oral tongue squamous cell carcinoma (OTSCC). Understanding patterns of tumor extension could improve a multimodal therapeutic approach. Thus, the main aim of this study was to provide a histological and microanatomical analysis of surgical specimens after compartmental surgery for OTSCC.

Intraoperative surgical navigation improves margin status in advanced malignancies of the anterior craniofacial area: A prospective observational study with systematic review of the literature and meta-analysis.

The current scientific evidence suggests that surgical navigation (SN) can contribute to improve oncologic outcomes in sinonasal and craniofacial surgery. The present study investigated the feasibility of intraoperative SN and its role in improving the outcomes of surgically treated sinonasal and craniofacial tumors. This prospective study compared navigation-guided surgery for sinonasal or craniofacial malignancies with a pair-matched cohort (1:2 matching) of patients operated without SN.

Ectopic olfactory neuroblastoma is associated with increased frequency of syndrome of inappropriate antidiuretic hormone secretion and reduced disease control: Case series with systematic review and pooled analysis.

Introduction: Olfactory neuroblastoma (ONB) is a rare malignant tumor originating from the olfactory neuroepithelium, typically within the sinonasal cavity. Cases of ONB originating outside of the olfactory cleft area are extremely rare and are referred to as "ectopic" (eONB), in contrast to "orthotopic" tumors (oONB). ONB has been associated with paraneoplastic syndromes (PNSs), including the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Late olfactory bulb involvement in COVID-19.

Transient or persistent hypo-anosmia is common in SARS‑CoV‑2 infection but olfactory pathway late-term morphometric changes are still under investigation. We evaluated late olfactory bulb (OB) imaging changes and their correlates with the olfactory function in otherwise neurologically asymptomatic COVID-19 patients. Eighty-three subjects (mean-age 43 ± 14 yr; 54 females; time-interval infection/MRI: 129±68 d) were affected by asymptomatic to mild COVID-19 in 2020 and 25 healthy controls (mean-age 40 ± 13 yr; 9 females) underwent 3T-MRI and olfactory function evaluation through anamnestic questionnaire and Sniffin' Sticks.

Management of frontal sinus and frontal recess inverted papilloma: our experience and systematic review.

Objective: For frontal sinus inverted papilloma (FSIP) management, an endoscopic endonasal approach (EEA) can be combined (or not) with an external approach by an osteoplastic flap (OPF) or with a more conservative open approach. The present study aims to describe our experience in the management of FSIP, focusing on disease-related and anatomical features influencing outcomes and recurrence.

Methods: This case series of FSIP investigated anatomical and disease-related predictors of recurrence associated with EEA or a combined EEA-OPF approach.

Epithelial-to-Mesenchymal Transition and Neoangiogenesis in Laryngeal Squamous Cell Carcinoma.

The mechanism of epithelial-mesenchymal transition (EMT) is fundamental for carcinogenesis, tumor progression, cancer cell invasion, metastasis, recurrence, and therapy resistance, comprising important events, such as cellular junction degradation, downregulation of epithelial phenotype markers, overexpression of mesenchymal markers, and increase in cellular motility. The same factors that drive epithelial cells toward a mesenchymal phenotype may also drive endothelial cells toward a proangiogenic phenotype. The aim of this exploratory study was to investigate a potential interplay between EMT and angiogenesis (quantified through CD105 expression) in laryngeal carcinoma (LSCC).

Prognostic impact of neutrophils-to-lymphocytes ratio (NLR), PD-L1 expression, and tumor immune microenvironment in laryngeal cancer.

Purpose: In laryngeal carcinoma (LSCC), tumor immune microenvironment is attracting increasing interest, given the recent progresses in immunotherapy. Immune cells migrate to tumors as a result of a tumor antigen-induced immune reaction and cancer cells recruit immune regulatory cells to induce an immunosuppressive network, resulting in the escape from host immunity. This interaction reflects both on tumor microenvironment and systemic inflammatory status.

Evolution of Altered Sense of Smell or Taste in Patients With Mildly Symptomatic COVID-19.

Importance: An altered sense of smell and taste has been reported to be associated with coronavirus disease 2019 (COVID-19). To understand the evolution of these symptoms during the course of the disease is important to identify patients with persistent loss of smell or taste and estimate the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the burden of olfactory and gustative dysfunctions.

Objective: To evaluate the evolution of the loss of sense of smell and taste in a case series of mildly symptomatic patients with SARS-CoV-2 infection.

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.

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.
