The purpose of this study was to evaluate by the means of Doppler ultrasound and phlebography the relationship between Ménière's disease (MD) and chronic cerebrospinal venous insufficiency (CCSVI) and to test whether angioplasty is effective in improving symptoms. Phase 1: 50 patients diagnosed with definite MD (American Academy of Otolaryngology 1995) who had gained no benefit from routine therapy, underwent echoenhanced color Doppler sonography using the Zamboni protocol to check for CCSVI. One-hundred healthy subjects matched for age and gender acted as controls. Phase 2: in 20 of echo-color Doppler positive Ménière's cases we performed a venogram and the diagnosis of associated CCSVI was confirmed. These patients were simultaneously treated by angioplasty of the internal jugular vein, then re-tested respect the baseline scales of MD. Out of a total of 50 patients with MD, an ultrasound diagnosis was made of CCSVI in 45 patients (90%). In the healthy population CCSVI is found in only 3% of cases (P<0.001). Twenty patients were given venograms that confirmed the CCSVI diagnosis. Finally, percutaneous transluminal angioplasty (PTA) proved to be effective in 90% of patients, with significant improvement of several scales of vestibular function at six months follow-up. There is a significant prevalence of CCSVI in patients with MD and treatment with PTA seems useful because of an improvement in symptoms and vestibular function recorded in the majority of patients.

During implant surgery procedures, surgical precision is an essential prerequisite for the functional and aesthetic success of the prosthetic crown to be placed on the dental implant. A modern implant surgical approach should be standardized as much as possible to guarantee extreme precision in the insertion of the implant into the upper and lower bone jaws. Among the most common surgical errors during implant surgery there is the over-preparation of the surgical alveolus with possible damage to the contiguous anatomical structures. To avoid this problem, in the recent years, there has been an increasing attention to the development of new control techniques. In this paper, we describe an innovative ultrasound approach, which exploits the integration of an electro-acoustic transducer with the surgical drill used for realizing the alveolus in the bone that will host the implant. Specifically, he proposed approach is based on the "time-of-flight" detection technique for measuring the thickness of the residual bone subjected to the drilling. In order to demonstrate the feasibility of the proposed approach, here we report on a detailed numerical analysis aimed at studying the propagation of ultrasonic waves through the drill-bit and through the involved tissues. The obtained results confirm the validity of our approach, and enable for a future first prototype implementation of a hi-tech surgical drill-bit, which in general is suitable not only for dental implant surgery but also for other uses in oral surgery, maxillofacial surgery and for bone surgery.

Background: Revision rhinoplasty is a technically demanding surgical procedure that can put every surgeon in trouble. The main issue of these cases is often an altered osteocartilaginous framework following over-resection during the first intervention. Moreover, the available septal or auricular cartilage for grafting is usually not enough. This review aims to examine contemporary advances in applications of fresh frozen cartilage in rhinoplasty. Methods: A structured review of the current literature (up to December 2023) was performed on four bibliographic databases: PubMed, EMBASE, Cochrane and Medline. The search terms were combinations of "Rhinoplasty" and "Cartilage Graft", "Allograft" or "Fresh Frozen Cartilage". The citations of selected studies and review articles were also evaluated if present. Results: The research resulted in 152 articles, and only ten met the inclusion criteria: nine clinical articles and one in vitro study. One of the ten eligible articles was excluded. Conclusions: Fresh frozen rib cartilage proved to be a viable alternative to autologous rib grafts and irradiated homologous rib graft. Despite the higher costs, FFRG can provide a sufficient amount of tissue for grafting avoiding donor site complications and reducing the operative time and proved to have more chondrocytes and to be less prone to resorption compared to irradiated rib.

Background: Eosinophilia can be influenced by multiple factors. This study aims to set a protocol for monitoring blood absolute eosinophil count (AEC) in patients with seasonal allergy affected by bronchial asthma (BA), allergic rhinitis (AR), or chronic rhinosinusitis with or without nasal polyposis (CRSw/sNP). Methods: We planned a total of four annual blood samples to measure AEC in- and out-seasonal pollen exposure (i.e., one measurement every three months for one year). Results: We identified two distinct groups of patients (non-eosinophilic and eosinophilic). Patients in the eosinophilic group presented with four different patterns (episodic, transient, floating, and persistent). Most patients with episodic, transient, and floating patterns were affected by mild allergy and the increase in eosinophils was related to allergen exposure. In contrast, patients with the persistent pattern mostly presented with more severe allergy (i.e., severe BA and relapsing CRSwNP) and the eosinophilia was unrelated to allergen exposure. The subgroup of patients with severe BA, relapsing CRSwNP, and persistent eosinophilc pattern were treated with benralizumab, which induced a noteworthy improvement in both severe BA and CRSwNP. Conclusions: Multiple AEC measurements in patients with seasonal allergy can better reflect patient's eosinophilic status and help define the relationship of AEC enhancement with allergen exposure.

Background: The anatomical complexity of the oropharynx and the difficulty in reaching its distal portion have always conditioned the surgical accessibility. Robotic surgery represents an excellent alternative in the treatment of cervico-facial oncological diseases. Methods: This series comprises all patients managed for head and neck cancer by Trans Oral Robotic Surgery TORS. The staging assessment, including neck ultrasound and total body PET/CT scan, was performed in each patient according to the TNM classification. All charts were recorded with the following data: name and surname, age, gender, date of surgery intra or post-operative hemorragia, tumor site, histology, TNM stage, robot set-up time, tumor resection time, whether or not tracheotomy was performed, whether or not neck dissection was performed, insertion of a nasogastric tube or gastrostomy, time to resumption of oral feeding, surgical margins, mean length of hospital stay, adjuvant treatment and follow-up. Results: From February 2013 to February 2018, TORS was performed in 67 consecutive patients affected by head and neck tumours. We divided, our sample, in 3 subsites: supraglottic larynx, parapharyngeal space and oropharynx. Pathology reports confimed malignancy in 44 cases: 8 cases lymphomas, 36 cases of Squamous cell carcinoma (SCC), 5 cases of benign salivary glands tumors and 18 miscellaneous cases. Neck dissection was performed in 12 cases. Tracheotomy was perfomed in 3/67 cases for respiratory failures. A nasogastric tube was inserted at the end of the surgical procedure in 21 patients. The mean length of hospital stay was 10 days. Major complications included post-operative bleeding in 3 patients, 1 exitus for massive bleeding 20 days post-surgery and 1 respiratory failure treated with tracheotomy and monitoring in the Intensive Care Unit (ICU) for 3 days. Conclusions: Robotic surgery has been considered a valid alternative to traditional open treatment in many specializations with the advantages of an endoscopic procedure, with the same oncological and functional results and with fewer complications. The advantages of this type of surgical technique have been discussed, it is mandatory to focus on the indications and contraindications. [ABSTRACT FROM AUTHOR]

A pharyngocutaneous fistula (PCF) is the most common complication after salvage total laryngectomy (STL) with an incidence ranging from 5 to 73%, causing an increase in morbidity and delaying the patient's recovery. A surgical technique to prevent PCF formation is the use of the stapler to suture the pharyngeal mucosa. We have reviewed the medical files of 91 patients who had undergone STL, dividing the patients into two groups (manual suture vs. stapler), based on the type of pharyngeal suture performed during the STL. We found 12/49 (24.5%) cases of a PCF in group A (manual) and 5/42 (11.9%) cases of a PCF in group B (stapler). There is a statistically significant difference between the two groups with the patients in group B presenting better results in terms of the reduction of the surgical time, the length of the hospital stay and also in the restarting of oral feeding. The advantages of mechanical suturing with the stapler are reduced surgical times, a lower PCF formation rate, which involves an early removal of the nasogastric tube, and reduced hospitalization times. Further studies with a larger case series will be necessary to confirm the results obtained and to standardize the surgical technique. [ABSTRACT FROM AUTHOR]

Background: The reconstruction of midface skin defects represents a challenge for the head and neck surgeon due to the midface's significant role in defining important facial traits. Due to the high complexity of the midface region, there is no possibility to use one definitive flap for all purposes. For moderate defects, the most common reconstructive techniques are represented by regional flaps. These flaps can be defined as donor tissue with a pedunculated axial blood supply not necessarily adjacent to the defect. The aim of this study is to highlight the more common surgical techniques adopted for midface reconstruction, providing a focus on each technique with its description and indications. Methods: A literature review was conducted using PubMed, an international database. The target of the research was to collect at least 10 different surgical techniques. Results: Twelve different techniques were selected and cataloged. The flaps included were the bilobed flap, rhomboid flap, facial-artery-based flaps (nasolabial flap, island composite nasal flap, retroangular flap), cervicofacial flap, paramedian forehead flap, frontal hairline island flap, keystone flap, Karapandzic flap, Abbè flap, and Mustardè flap. Conclusions: The study of the facial subunits, the location and size of the defect, the choice of the appropriate flap, and respect for the vascular pedicles are the key elements for optimal outcomes.

Cartilage grafts are well-known as being reliable in reconstructive surgery for craniofacial pathologies. The aim of this study is to describe a new technique which requires an incision smaller than 1.5 cm but is still effective for harvesting cartilage graft. Thirty-six patients who underwent costal cartilage harvesting for septorhinoplasty have been included in this study, admitted from January 2018 to December 2021. Out of 36 patients, 34 have not reported any major complications, and two cases were followed up for pneumothorax. There were no infections and no chest wall deformities. All patients reported minimal pain at the donor site. The Vancouver Scar Scale was used to evaluate the entity of the postoperative scarring phenomena. This scale total ranges from 0 (representing normal skin) to a maximum score of 13 (representing worst scar imaginable). The results were 1.53 SD ± 0.64 (on average) 1 week after the surgical procedure and 1.28 SD ± 0.45 (on average) at the 6 months follow-up. This minimally invasive method provided a valid and effective surgical technique for cartilage graft. Despite the limitations of the case series, it seems that this procedure might be comparable to other and well-established traditional procedures and could be even preferred when the minimal invasiveness is mandatory.

Although scalp defects can vary in size and thickness, scalp avulsion represents a rare occurrence. This type of lesion may have different origins, but it is usually related to long hair being caught in agricultural machinery. The management of full-thickness scalp defects poses a challenge to the head and neck surgeon due to the possible involvement of neurovascular structures and scar retraction, which can affect the esthetic restoration of the area. Several algorithms for the choice of scalp reconstruction have been proposed in the literature and different techniques are available for extensive scalp defect reconstruction (local soft tissue flap, microvascular free flap, and skin graft combined with dermal substitutes), based upon the scalp defect type. Here we describe six cases of patients with total scalp avulsion, which required a combined reconstruction with a split-thickness skin graft (STSG) and Integra® matrix immediately after the trauma.

Simple Summary: The management of salivary gland tumors (SGTs), especially their early diagnosis, remains a challenge for physicians. Indeed, differentiating benign and malignant SGTs is an essential step in choosing an appropriate surgical approach. The aim of this study was to increase the effectiveness of pre-surgical diagnosis through a machine learning (ML) diagnostic tool that evaluates inflammatory biomarkers and radiomic metrics extracted from magnetic resonance imaging (MRI) sequences. Specifically, we considered the following indices of inflammation as inflammatory biomarkers: the systemic immune-inflammation index (SII), the systemic inflammation response index (SIRI), the platelet-to-lymphocyte ratio (PLR), and the neutrophil-to-lymphocyte ratio (NLR). In the context of cancer research, however, radiomics enables high-performance quantitative analysis of radiological images. We concluded that inflammatory biomarkers and radiomic features are comparably capable of supporting a differential diagnosis and are easily obtained through the preclinical investigations of patients. Background: The purpose of this study was to investigate how the systemic inflammation response index (SIRI), systemic immune-inflammation index (SII), neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR), and radiomic metrics (quantitative descriptors of image content) extracted from MRI sequences by machine learning increase the efficacy of proper presurgical differentiation between benign and malignant salivary gland tumors. Methods: A retrospective study of 117 patients with salivary gland tumors was conducted between January 2015 and November 2022. Univariate analyses with nonparametric tests and multivariate analyses with machine learning approaches were used. Results: Inflammatory biomarkers showed statistically significant differences (p < 0.05) in the Kruskal–Wallis test based on median values in discriminating Warthin tumors from pleomorphic adenoma and malignancies. The accuracy of NLR, PLR, SII, and SIRI was 0.88, 0.74, 0.76, and 0.83, respectively. Analysis of radiomic metrics to discriminate Warthin tumors from pleomorphic adenoma and malignancies showed statistically significant differences (p < 0.05) in nine radiomic features. The best multivariate analysis result was obtained from an SVM model with 86% accuracy, 68% sensitivity, and 91% specificity for six features. Conclusions: Inflammatory biomarkers and radiomic features can comparably support a pre-surgical differential diagnosis. [ABSTRACT FROM AUTHOR]

Zygomaticomaxillary complex and isolated orbital walls fractures are one of the most common fractures of the midface, often presenting orbital symptoms and complications. Our study was born with the aim of understanding the trend in the incidence of orbital presurgical symptoms, specifically diplopia, enophthalmos and exophthalmos, in the Campania Region in southern Italy. We conducted a retrospective, monocentric observational study at the Maxillofacial Surgery Unit of the Federico II University Hospital of Naples, enrolling 402 patients who reported a fracture of the zygomaticomaxillary complex and orbital floor region from 15 June 2021 to 15 June 2022. Patients were evaluated by age, gender, etiology, type of fracture, preoperative orbital side effects and symptoms. Pre-surgical side effects were studied, and 16% of patients (n = 66) developed diplopia. Diplopia was most common in patients previously operated on for orbital wall fractures (100%), and least common in patients who reported trauma after interpersonal violence (15%) and road traffic accidents (11%). Exophthalmos appeared only in 1% (six cases); whereas it did not appear in 99% (396 cases). Enophthalmos was present in 4% (sixteen cases), most commonly in interpersonal violence cases (two cases). The frequency of orbital complications in patients with zygomaticomaxillary complex and isolated orbital walls fractures suggests how diplopia remains the most common pre-surgical orbital side effect.

Purpose: Orbital floor Fractures are the most common fractures involving the facial skeleton and usually occurs after traumatic events. The reconstruction of the orbital floor can be performed with different biocompatible materials. The aim of our retrospective study is to analyze the short- and long-term outcomes of surgically treated patients based on the material used to repair the orbital floor. Methods: We enrolled 146 patients hospitalized for orbital floor fractures in the Maxillofacial Surgery Unit of the Federico II University of Naples from 1 to 2010 to July 2020. All the fractured orbital floors were reconstructed with non-resorbable (Titanium Mesh, SynPor, SuPor and MedPor implants) or resorbable (collagen membrane, bovinum pericardium membrane, autologous bone graft) materials. Results: We utilized non-resorbable materials in 56% (82 cases) and resorbable implants in 44% (64 cases). An improvement of the preoperative symptomatology and an aesthetical good outcome was achieved in most cases. Conclusions: Data obtained supports that both resorbable and non-resorbable materials for orbital floor reconstruction are a safe and effective alternatives and offer satisfactory results in functional and aesthetic evaluations.

Simple Summary: Clinical management of Malignant Salivary Gland Tumors is still a challenge for clinicians. Direct and indirect costs for the diagnosis and treatment of these tumors are significant. For this reason, the need to develop a fast and low-cost prognostic system to stratify patients at higher risk appears to be mandatory. The efficacy of inflammatory biomarkers such as the systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR), as prognostic values that are quickly available and low cost, has been confirmed in various fields of oncology. The aim of this study was to investigate the impact of these biomarkers taken individually and combined, to assess the overall survival (OS) in patients surgically treated for malignant salivary gland tumors. This study determined that the combination of SII + SIRI can independently predict the overall survival of patients after surgery for malignant salivary gland tumors. Background: The aim of this study was to investigate how the systemic inflammation response index (SIRI), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), taken individually and combined, are associated with overall survival (OS) in patients surgically treated for malignant salivary gland tumors (MSGTs). Methods: A retrospective analysis of 74 cases following surgery at our department between January 2011 and June 2018 was performed. The Receiver Operating Characteristic (ROC) curve was used to calculate the optimal cutoff values for SII, SIRI, PLR, and NLR. Survival curves of different groups at 1–3–5 years were estimated using the Kaplan–Meier method. Results: The optimal thresholds with the highest sensitivity and specificity were 3.95 for NLR, 187.6 for PLR, 917.585 for SII, and 2.045 for SIRI. The ROC curves revealed that the best combination with AUC = 0.884 was SII + SIRI. The estimated 5-year OS probability in patients with SII+ SIRI scores of 0, 1, and 2 was 96%, 87.5% and 12.5%, respectively (p < 0.001). Conclusion: SII+ SIRI can independently predict the OS of patients after MSGT surgery. The prognostic score system based on SII+ SIRI may be good clinical practice as a reference for clinical decision-making. [ABSTRACT FROM AUTHOR]

Methods: A retrospective analysis of patients treated for scalp region reconstruction was conducted with 16 patients. All patients underwent the same procedure: scalp full-thickness tumor excision with simultaneous reconstruction with Matriderm® and the application of a split-thickness skin graft in the same surgical time. During follow-ups, the surgical outcome was evaluated by accurate clinical examination of the wound, adopting the Vancouver Scar Scale (VSS). Results: The outcomes obtained were satisfying: wound healing at the end of the procedures was optimal, grafted skin resulted similar to surrounding tissue, and pigmentation and vascularity showed a decrease in the period between 6 months and 1 follow-up. Conclusions: The use of Matriderm® and split-thickness skin grafting for scalp full-thickness defects reconstruction resulted in an optimal, stable, and safe procedure, suitable for elderly patients.

Hyaluronic Acid (HA) plays many roles in wound healing in general, through different mechanisms. Several authors reported the effectiveness of hyaluronic acid in promoting mucosal healing and reducing discomfort for patients after endoscopic sinus surgery (ESS). Different methods for HA nasal administration have been reported. The aim of our study has been to evaluate the efficacy of the administration of nebulized HA through a nasal douche compared with its administration through a nasal spray with patients undergoing ESS for chronic rhinosinusitis. From January 2013 to January 2019 a prospective clinical trial was carried out in our hospital with 163 patients who had undergone ESS for chronic rhinosinusitis. The sample was divided into three groups according to the method of administration of HA. Our study confirm the efficacy of the administration of nebulized HA through nasal douche in post-operative care (6.5% vs 4.5%). The most relevant data regards the nasal dryness sign: the data revealed an unexpected percentage of worsening of that sign at time T3 (p = 0.049) particularly evident in the patients treated with HA through nasal douche compared to whom the nasal spray device was prescribed (4% vs 1%). Further studies are needed to identify the best means of administration of HA, which would satisfy the requirements for efficacy in terms of the results and, at the same time, patient compliance.

Systemic sclerosis (SSc) is a heterogeneous, chronic connective tissue disease, characterized by skin fibrosis as well as vascular and visceral lesions. It can involve the lungs, heart, kidneys, gastrointestinal tract, and bones. The orofacial manifestations of SSc can cause functional, aesthetic, and social distress, resulting in significant psychological implications for the patients. In recent decades, fat grafting improved the aesthetic outcomes in terms of volume deficiency, contour asymmetry, and skin elasticity of the face thanks to the regenerative action of the stem cells contained within it. We describe five cases of a patient with SSc treated with fat grafting used to correct volume loss and facial elasticity of the lips and perioral region on the middle and lower third of the face. All the patients received regular postoperative checks at weeks 1 and 2. A multiple choice questionnaire was administered to assess the degree of tolerability of the procedure. The reliability of the questionnaire was evaluated by calculating the Cronbach alpha using the MedCalc Statistical Software version 20.113. The aim of our study is to describe three different types of fat grafting used to correct volume loss and restore facial elasticity of the lips and perioral region on the middle and lower third of the face.

Simple Summary: The purpose of this study is to predict the risk of metastatic lymph nodes related to oral tongue squamous cell carcinoma (OTSCC) and tumor grading through the combination of clinical data with radiomics metrics extracted from computed tomography (CT) images. We aimed to develop a supportive approach in the management of lymphatic cervical areas, with particular attention given to the early stages (T1−T2). Specifically, we evaluated the effectiveness of the radiomics and clinical features in the study of OTSCC and in the prediction of occult laterocervical metastatic lymph nodes. We concluded that radiomics features and clinical parameters have an important role in identifying tumor grading and metastatic lymph nodes. Machine learning approaches can be used as an easy-to-use tool to stratify patients with early-stage OTSCC, based on the identification of metastatic and non-metastatic lymph nodes Objective: To predict the risk of metastatic lymph nodes and the tumor grading related to oral tongue squamous cell carcinoma (OTSCC) through the combination of clinical data with radiomics metrics by computed tomography, and to develop a supportive approach in the management of the lymphatic cervical areas, with particular attention to the early stages (T1−T2). Between March 2016 and February 2020, patients with histologically confirmed OTSCC, treated by partial glossectomy and ipsilateral laterocervical lymphadenectomy and subjected to computed tomography (CT) before surgery, were identified by two centers: 81 patients (49 female and 32 male) with 58 years as the median age (range 19–86 years). Univariate analysis with non-parametric tests and multivariate analysis with machine learning approaches were used. Clinical, hematological parameters and radiological features extracted by CT were considered individually and in combination. All clinical parameters showed statistically significant differences (p < 0.05) for the Kruskal−Wallis test when discriminating both the tumor grading and the metastatic lymph nodes. DOI, PLR, SII, and SIRI showed an accuracy of 0.70 (ROC analysis) when identifying the tumor grading, while an accuracy ≥ 0.78 was shown by DOI, NLR, PLR, SII, and SIRI when discriminating metastatic lymph nodes. In the context of the analysis of radiomics metrics, the original_glszm_HighGrayLevelZoneEmphasis feature was selected for identifying the tumor grading (accuracy of 0.70), while the wavelet_HHH_glrlm_LowGrayLevelRunEmphasis predictor was selected for determining metastatic lymph nodes (accuracy of 0.96). Remarkable findings were also obtained when classifying patients with a machine learning approach. Radiomics features alone can predict tumor grading with an accuracy of 0.76 using a logistic regression model, while an accuracy of 0.82 can be obtained by running a CART algorithm through a combination of three clinical parameters (SIRI, DOI, and PLR) with a radiomics feature (wavelet_LLL_glszm_SizeZoneNonUniformityNormalized). In the context of predicting metastatic lymph nodes, an accuracy of 0.94 was obtained using 15 radiomics features in a logistic regression model, while both CART and CIDT achieved an asymptotic accuracy value of 1.00 using only one radiomics feature. Radiomics features and clinical parameters have an important role in identifying tumor grading and metastatic lymph nodes. Machine learning approaches can be used as an easy-to-use tool to stratify patients with early-stage OTSCC, based on the identification of metastatic and non-metastatic lymph nodes.

Introduction: Nowadays, with the start of the vaccination campaign is very important to assess the extent of exposure of the population and identifying rapid, sensitive and accurate test to quickly identify new cases of SARS-CoV-2. The rapid test, cheap and easy to perform, is therefore very useful in developing countries, where the vaccination campaign has not yet reached adequate coverage. Methodology: We compared the VivaDiag COVID-19 IgM/IgG Rapid Test (VivaCheck Biotech Co., Ltd) with the Roche Elecsys Anti-SARSCoV-2 (Roche Diagnostics, Rotkreuz, Switzerland) to recognize past infections and to compare VivaDiag COVID-19 IgM/IgG Rapid Test (VivaCheck Biotech Co., Ltd) with Abbott Real Time PCR SARS-CoV-2 assay to recognize infection during its acute phase so that it’s possible to evaluate the use of commercially available assays in clinical practice. Results: Of the 1,100 patients tested with serological and rapid test, 1,085 were negative both to serological and rapid test, 4 patients were positive at rapid (2 for IgM and 2 for IgG) but negative serological test, 11 patients were positive at serological test but negative to rapid. Of the 300 tested with oropharyngeal swab and rapid test, 294 were negative both to swab and rapid test, 2 positives both to swab and rapid test, 3 positives at swab but negative at rapid test, 1 negative at swab but positive at rapid test. Conclusions: the combined use of these tests according to the specific needs of users, allows a reliable identification of infected patients in the acute phase, distinguishing them from subjects with an antibody response from a previous infection.

Background: COVID-19 is a global pandemic. The virus spreads through respiratory droplets and close contact. Therefore, the availability of personal protective equipment (PPE) for healthcare professionals is essential. 3D printing technology could represent a valid option to ameliorate PPE shortages. Methodology: Custom-made face mask were designed on the basis of facial scan and then 3D-printed. The whole protocol is executed with freeware software and only required a 3D printer. Six healthcare workers wore the device weekly thus expressing a judgment regarding quality of work, respiratory and skin comfort. Results: The estimated total cost of a single mask is approximately 5 USD. The virtual design of a complete mask lasted 68 minutes on average. Most healthcare workers rated comfort as very good. Conclusions: Based on the encouraging results obtained, we can confidently confirm that custom-made masks are novel and useful devices that may be used in the fight against COVID-19.

Introduction: We described a rare clinical case of osteoma associated with homolateral radicular cyst of the maxillary sinus. Observation: Imaging showed two different lesions in the right maxillary sinus. We performed a combined surgical approach to completely remove the lesions and used a plasma rich in growth factors membrane to repair dental roots. No relapse after a 2 years follow-up was observed. Commentaries: The simultaneous presence of two large lesions, a 23,7 mm osteoma and a 33,7 mm radicular cyst in the same maxillary sinus, has been rarely described in the literature. Although nasal endoscopy and imaging are mandatory to assess the diagnosis, the definitive diagnosis was obtained after histopathologic examination. A combined surgical approach allowed a complete removal of both lesions, ensuring, at same time, an optimal surgical field. Plasma rich in growth factors membrane due to its cohesive properties was particularly useful in improving bone neoformation and periodontal regeneration. Conclusion: Diagnostic assessment of maxillary lesions requires nasal endoscopy, imaging and histopathological examination. If these lesions are symptomatic, they should be completely removed and minimally invasive surgery is indicated. Plasma rich in growth factors membrane ensures a good postoperative recovery.

While fenestration and duplication are relatively common in the arteries, they are extremely rare in the venous compartment: internal jugular vein fenestration has been reported occurring in 0.4% of unilateral neck dissections. Familiarity with these morphological anomalies is important for the radiologist and for the surgeon to prevent neurovascular injury, especially in neck surgery and interventional catheterization. We present the case of a patient harboring a fenestration of the left internal jugular vein, diagnosed by magnetic resonance angiography, and a systematic review of the literature. To our knowledge, from 1985 until 2016 only 36 patients (including the present) were diagnosed as having an internal jugular vein morphological anomaly. Out of 36 patients, only 11 (30,5%) were diagnosed using radiological imaging; the high rate of intraoperative diagnoses (22/36, 62,5%) is likely related to the limited use of diagnostic imaging or to misdiagnosis/misinterpretation of a relatively unknown and rare morphological anomaly. A contrast enhanced computed tomography or magnetic resonance angiography should be considered in case of vascular procedures in a patient with known internal jugular vein anomaly.

SQUAMOUS cell carcinoma , *ETHNICITY , *CADHERINS , *CANCER cells , *IMMUNOHISTOCHEMISTRY - Abstract
The oral tongue is the most common site for tumours within the oral cavity. Despite intense research, there has been no improvement in the survival rate for patients with oral tongue squamous cell carcinoma (OTSCC) during the last decades. Differences between oral cancer patients based on ethno-geographical distribution have been reported. The present study used immunohistochemistry to evaluate commonly used markers of cancer cell phenotypes, E-cadherin, β-catenin and cytokeratins 5 and 19, in 120 patients with OTSCC. To evaluate the impact of ethnicity, patients from Sweden and Italy were included. A higher proportion of Swedish patients exhibited high expression of E-cadherin in their tumours (P=0.039), and high levels of E-cadherin in Swedish OTSCC patients that had succumbed to their disease were associated with poor prognosis. These data demonstrated differences in the pathological characteristics of OTSCC between two different European populations. The findings emphasise the need to take ethnicity/geographical location of patients into account when comparing results from different studies of OTSCC. [ABSTRACT FROM AUTHOR]

- Abstract
Human Papilloma Virus infection is very frequent in humans and is mainly transmitted sexually. The majority of infections are transient and asymptomatic, however, if the infection persists, it can occur with a variety of injuries to skin and mucous membranes, depending on the type of HPV involved. Some types of HPV are classified as high oncogenic risk as associated with the onset of cancer. The tumors most commonly associated with HPV are cervical and oropharyngeal cancer, epigenetic mechanisms related to HPV infection include methylation changes to host and viral DNA and chromatin modification in host species. This review is focused about epigenethic mechanism, such as MiRNAs expression, related to cervix and oral cancer. Specifically it discuss about molecular markers associated to a more aggressive phenotype. In this way we will analyze genes involved in meiotic sinaptonemal complex, transcriptional factors, of orthokeratins, sinaptogirin, they are all expressed in cancer in a way not more dependent on cell differentiation but HPV-dependent.

Background Optimum management of clinically negative neck (cN0) remains controversial in early stage (T1-T2) squamous cell cancer of the oral tongue (OTSCC). The purpose of this study was to investigate the value of pre-treatment Neutrophil-to lymphocyte ratio (NLR) in predicting occult cervical metastasis in stage I and II OTSCC. Methods We carried out a retrospective chart review on 110 patients suffering from early stage OTSCC who were surgically treated with tumour excision and elective neck dissection (END). Our cohort was divided in pN+ and pN0 groups basing on histopathological examination after elective neck dissection. For each patient pre-treatment NLR was calculated. Results A statistically significant relationship between high levels of pre-treatment NLR and probability rate for neck occult metastases (0.000496 p-value) has been found. On our model the cut-off value was set for NLR >2.93. Above this level the probability to finding metastasis in a clinically negative neck increases exponentially. Conclusion These preliminary results offer clinicians an easily obtainable tool to stratify patients based on risks of metastatic node in whom END could be indicated. [ABSTRACT FROM AUTHOR]

MANDIBULAR joint , *CAD/CAM systems , *COMPUTER-aided design , *TUMOR growth , *DIAGNOSTIC imaging - Abstract
Facial symmetry, as well as function, remains the big challenge for surgeons who attempt mandibular reconstruction. Nowadays several studies recommend the use of computer aided surgery (CAS) and CAD/CAM technology to guide mandibular segmental osteotomies and reconstruction using free fibula flap. Although these systems have radically changed the way of doing mandibular reconstructive surgery, they are expensive and require extended periods of time for prototypation. This may be an important limitation in case of malignant neoplasms which require short-term treatment. The aim of our study is to investigate the reliability and efficiency of a protocol to obtain cutting guides produced in a "homemade" way. This study includes four consecutive patients who underwent a segmental mandibulectomy and fibula osteo-cutaneous free flap reconstruction for oral squamous cell carcinoma between January and September 2016. The CAD/CAM system algorithm proposed was based on the use of free open source software for digital planning and 3D layer plastic deposition printer. A cost of about 3 Euro for each case was estimated. An average mean distance between 3D preoperative and postoperative mesh points of 1.631 mm and a standard deviation of 5.496 mm has been demonstrated by 3D volume overlay analysis. Overlapping results with much shorter prototyping time was required with the in-house procedure described as compared to the available commercial system. In conclusion, we expect that this technique will reduce operative time and cost however further study and large series are needed to confirm our results and better define the applicability in everyday surgical practice.

Granular cell tumor (GCT), a relatively rare neuroectodermal tumor occurring most often in the head and neck region, is not uncommonly associated with pseudoepitheliomatous hyperplasia of the overlying surface epithelium, which may be at times nonreadily distinguishable from well-differentiated squamous cell carcinoma (SCC). To the best of our knowledge, only a handful of coexisting SCC and GCT, mostly described in the esophagus, have been reported in (the current) literature so far. We herein report 2 new cases of coexisting GCT and SCC of the head and neck region, located, respectively, in larynx and tongue; comment on their clinical, imaging, and pathologic features; and discuss their management. In the present work, we also review the literature concerning this association to contribute to the head and neck pathologists' and surgeons' awareness regarding the possibility of this association for an adequate surgical excision and a better management of these patients.

Background: c-MYC is a potent oncoprotein with roles in a wide range of cellular processes such as differentiation, apoptosis and growth control. Deregulation of the MYC gene is commonly seen in human tumours resulting in overexpression of the protein. Here we studied expression of c-MYC in correlation to clinical outcome in patients with primary squamous cell carcinoma of the mobile tongue.Methods: Immunohistochemistry was used to identify c-MYC in a group of 104 tongue squamous cell carcinomas with an antibody directed against the N-terminal part of the protein. Staining was evaluated by multiplying the percentage of c-MYC-expressing cells with staining intensity, giving a quick score for each tumour.Results: All 104 tumours expressed c-MYC at varying levels. Quantitation according to per cent of positive cells and staining intensity revealed that most (15/21; 71%) high-expressing tumours were seen in males. Within the group of high c-MYC-expressing tumours, the majority were alive 2 and 5 years after treatment.Conclusions: The present findings show that expression of c-MYC has prognostic value in squamous cell carcinoma of the tongue, and could be useful in choice of therapy.

EPSTEIN-Barr virus , *SQUAMOUS cell carcinoma , *TONGUE cancer , *OROPHARYNX - Abstract
Squamous cell carcinoma of the head and neck (SCCHN) comprises a large group of cancers in the oral cavity and nasopharyngeal area that typically arise in older males in association with alcohol/tobacco usage. Within the oral cavity, the mobile tongue is the most common site for tumour development. The incidence of tongue squamous cell carcinoma (TSCC) is increasing in younger people, which has been suggested to associate with a viral aetiology. Two common human oncogenic viruses, human papilloma virus (HPV) and Epstein-Barr virus (EBV) are known causes of certain types of SCCHN, namely the oropharynx and nasopharynx, respectively. EBV infects most adults worldwide through oral transmission and establishes a latent infection, with sporadic productive viral replication and release of virus in the oral cavity throughout life. In view of the prevalence of EBV in the oral cavity and recent data indicating that it infects tongue epithelial cells and establishes latency, we examined 98 cases of primary squamous cell carcinoma of the mobile tongue and 15 cases of tonsillar squamous cell carcinoma for the presence of EBV-encoded RNAs (EBERs), EBV DNA and an EBV-encoded protein, EBNA-1. A commercially available in situ hybridisation kit targeting EBER transcripts (EBER-ISH) showed a positive signal in the cytoplasm and/or nuclei of tumour cells in 43% of TSCCs. However, application of control probes and RNase A digestion using in-house developed EBER-ISH showed identical EBER staining patterns, indicating non-specific signals. PCR analysis of the BamH1 W repeat sequences did not identify EBV genomes in tumour samples. Immunohistochemistry for EBNA-1 was also negative. These data exclude EBV as a potential player in TSCC in both old and young patients and highlight the importance of appropriate controls for EBER-ISH in investigating EBV in human diseases.

Introduction: The midcheek is considered one of the most important facial area due to its involvement in mimic expression and communication. Pathology of this district is complex due to the variety of soft tissue belonging to the face. We propose a surgical simulation, to assess the feasibility of a new minimally invasive endoscopic approach for midcheek mass removal. Technical report: This study was performed on four cadavers, at the Anatomy Laboratory of the University of Tubingen. In all the cadavers 3 cm³ of Acquasil Dent Sply Ultra were injected via trans-cutaneous along the nasolabial fold to simulate a midcheek mass. Three incisions in concealed areas were performed to create an access to reach the anterior compartment of the face. By using the Optical Dissector with distal spatula and a 30° endoscope we provided a wide surgical window and a greater exposure to isolate, dissect and remove the midcheek tumor model safely. Conclusion: The proposed endoscopic technique allowed us to visualize and preserve all the key anatomic structures of the midcheek region. Due to its nature, the suggested material may provide a valid tumor model for surgical training also in other districts. [ABSTRACT FROM AUTHOR]

Facial surgery remains a challenge for surgeons in order to achieve the best results, both functionally and aesthetically. Current endoscopic application also includes facial traumatology, such as zygomaticomaxillary complex fractures, frontal sinus fractures, mandibular condyle fractures, orbital floor fracture, and medial orbital wall fractures [[9]]. Surgical techniques, computer-assisted surgery, biomaterials research, and minimally invasive nonsurgical and surgical procedures for facial rejuvenation and reconstruction warrant in-depth investigation in order to ensure better results for patients.

Conversely, the involved SC function could likely be impaired in patients with BPPV presenting with persistent/long-lasting positional nystagmus, as in this condition otoconia might be partially entrapped in stenotic tracts of the membranous canal acting as an "incomplete" canalith jam [[2], [4]]. Letter to the editor regarding "Clinical significance of video head impulse test in benign paroxysmal positional vertigo: a meta-analysis" by Elsherif M et al. Therefore, we suggest that vHIT data of the affected canal might change depending on how and where otoconia are disposed within the canal [[4]] rather than on the affected canal itself.

Up-to-date, several molecular markers of prognosis have been studied in Oral Squamous Cell Carcinoma (OSCC), but none entered in the clinical setting. Therapy of OSCC tumors mainly relies on surgery, radiotherapy and partially on chemotherapy; there is an urgent need for biomarkers able to better stratify OSCC patients' risk to address targeted therapeutic strategies. The role of immune response in the pathogenesis and biological behavior of OSCC has been investigated by several authors, and promising results have been obtained with immune checkpoint inhibitors. We already investigated the role of the immune modulator FK506-binding protein 51 (FKBP51), a FK506-binding immunophilin, in cutaneous melanoma biology, and its expression in several human solid tumors. In the present study, we aimed to assess the value of FKBP51 expression in OSCC tumor cells as a marker of outcome. We collected clinical data from 72 patients who underwent surgery for Squamous Cell Carcinoma (SCC) of the tongue, floor, lips and palate. FKBP51 expression was assessed by immunohistochemistry on paraffin-embedded tumor tissues. In addition, we evaluated the human papillomavirus (HPV) status of primary tumors by immunohistochemistry, viral subtyping and In Situ Hybridization (ISH) assay. We found that high FKBP51-expressing tumors characterized the OSCCs with the worst prognosis: the high immunohistochemical expression of FKBP51 associated with death occurring within five years from the diagnosis with a sensitivity of 88.46% and a specificity of 91.67%. The estimated positive predictive value of the test was 88.45% and negative predictive value 91.67%. We tested FKBP51 mRNA presence, by RT-PCR assay, in a selected series of OSCC tumors, and we found that mRNA correlated well to the protein expression and to the clinical outcome. Applying the Bayes formula, we estimated an 88% probability of dying within five years from the diagnosis of OSCC patients with a high FKBP51 immunohistochemical (IHC) test result (>51% of FKBP51 positive tumor cells). On the basis of our analysis, we propose tumor tissue expression of FKBP51 protein as a reliable prognostic marker for OSCC tumors. [ABSTRACT FROM AUTHOR]

NASAL surgery , *MAXILLECTOMY , *ENDOSCOPIC surgery , *INTRANASAL medication , *SURGICAL excision - Abstract
Background The infraorbital nerve (ION) is a terminal branch of the maxillary nerve (V2) providing sensory innervation to the malar skin. It is sometimes necessary to sacrifice the ION and its branches to obtain adequate maxillary sinus exposure for radical resection of sinonasal tumors. Consequently, patients suffer temporary or permanent paresthesia, hypoestesthia, and neuralgia of the face. We describe an innovative technique used for preservation of the ION while removing the anterior, superior, and lateral walls of the maxillary sinus through a medial endoscopic transnasal maxillectomy. Methods All patients who underwent transnasal endoscopic maxillectomy with ION transposition in our institute were retrospectively reviewed. Results Two patients were identified who had been treated for sinonasal cancers using this approach. No major complications were observed. Transient loss of ION function was observed with complete recovery of skin sensory perception within 6 months of surgery. One patient referred to a mild permanent anesthesia of the upper incisors. No diplopia or enophthalmos were encountered in any of the patients. Conclusion The ION transposition is useful for selected cases of benign and malignant sinonasal tumors that do not infiltrate the ION itself but involve the surrounding portion of the maxillary sinus. Anatomic preservation of the ION seems to be beneficial to the postoperative quality of life of such patients. [ABSTRACT FROM AUTHOR]

NECK dissection , *WATCHFUL waiting , *TONGUE cancer , *SQUAMOUS cell carcinoma ,TOBACCO & health - Abstract
Background: Early oral squamous cell carcinoma (EOSCC) represents about 90% of the oral cancers especially in older males. The etiology is multifactorial, strongly related to tobacco and alcohol abuse, but also infective agents, Human papillomaviruses (HPV16-18), genetic factors and pre-neoplastic lesions seem to be implicated. There is no consensus in the literature for the treatment of early squamous cell carcinoma of the tongue (stages IeII); both an elective neck dissection policy and a watchful-waiting policy have their proponents in the different centers. Methods: The records of 127 patients with EOSCC of the tongue treated in our Department between 2007 and 2011, with cN0 neck staging, who underwent resection of the primary tumor with or without elective neck dissection, were reviewed. Results: We divided the patients into two groups, in Group 1 the 66 patients who received an elective neck dissection 30 days later from the primary surgery have been included, and in Group 2 the 61 patients undergoing "watchful waiting" observation for the development of nodal metastases have been collected. Statistical calculations were performed using Chi-square and t student test. Conclusions: A significant difference was found between the two groups as concerns tumor stage and pathologic tumor classification (p < 0.001). No significant differences were present between the two groups as concerns mean follow up (P = 0.2), relapse rate (p = 0.3) and relapse-free survival time (p = 0.2). In T1 stage tumors with depth of infiltration ≼4 mm, or low grade (G1-G2), the "watchful waiting" strategy for cervical metastases is appropriate, given the low regional recurrence rate (15%) and overall survival of 100%. In case of T2 lesions with depth of infiltration ≽4 mm or high grade (G3) we prefer to perform the elective neck dissection, with 13% of local recurrence and 100% of survival at 6 years.

Background: Orbital fracture usually occurs as a result of blunt orbital and facial trauma and may involve ocular injuries. International studies on orbital floor fracture show several differences in epidemiology, diagnostic criteria, surgical treatment modalities, and complication rates; therefore, any comparison should be made with caution. Here we describe an unusual case involving a 19-year-old man with violence-related periorbital trauma, wherein a foreign body (a plastic pen cap) traversed the median wall of the maxillary sinus and penetrated the lower turbinate.Case Presentation: A 19-year-old Caucasian man was referred to our department with localized pain and swelling in the left suborbital region following a physical fight in May 2014. A clinical examination revealed no abnormalities in his eyeballs or eye movement, palpation of the orbital contour revealed no fractures, and ophthalmological evaluation showed no evidence of diplopia. A computed tomography scan revealed fractures in the left orbital floor, periorbital tissue herniation without muscular entrapment and left maxillary hemosinus were observed. A hypodense soft tissue mass was lodged in the left orbital floor, which extended to the median wall of the maxillary sinus and penetrated the left lower turbinate. Surgical exploration of the foreign body was conducted, revealing the foreign body to be a pen cap.Conclusions: History or clinical examination alone may be inadequate to raise the suspicion of a retained periorbital foreign body in a situation of orbital region trauma. Computed tomography is important for the evaluation of periorbital injuries, especially because it could reveal the presence of a foreign body. Periorbital foreign bodies can be observed distinctly on computed tomography, which remains the most sensitive study and should be the first imaging modality in such cases.

Human head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type worldwide, possibly due to the significant role of alcohol and tobacco use in its development. Underlying most cancers are defects in mitochondrial functions such as energy metabolism and apoptosis. In fact, the mutations in mitochondrial DNA (mtDNA), which encode proteins for oxidative phosphorylation (OXPHOS), have been associated with human head and neck cancers. Here, we investigated the changes in the expression of OXPHOS complexes and the contribution of the defects in mitochondrial translation in the progression of HNSCC. Western blot analyses of the several stage IVA HNSCC primary tumors have shown reduction in the expression of COII and ATP5A of the OXPHOS complexes IV and V subunits, respectively. On the other hand, expression of the majority of the OXPHOS subunits, except complex II SDHB subunit, was impaired in a patient with a stage IV tumor with a regional lymph node. Interestingly, an overall reduction in one of the mitochondrial-encoded subunits of the complex IV, COII, accentuated a possible defect in mitochondrial translation machinery in two of the stage IVA tumors. Evidence provided in this study suggests for the first time that the mitochondrial translation defect(s) could be due to a decrease in the expression of one of the essential mitochondrial ribosomal proteins, MRPL11, in head and neck tumor biopsies. We also observed an acquired mitochondrial translation deficiency in the HN8 cell line derived from a lymph node metastasis but not in the HN22 cells derived from the primary tumor of the same patient. These seminal observations suggest that the mitochondrial translation machinery deserves further investigation for accurate molecular assessment and treatment of HNSCC. [ABSTRACT FROM AUTHOR]

LIPOMA , *BENIGN tumors , *TISSUE wounds , *TONGUE physiology , *TONGUE diseases - Abstract
Introduction: Lipoma is a benign tumor infrequent in the oral cavity, particularly in the tongue: indeed, lipomas only represent approximately 0.3% of all tongue neoplasia. Compared to conventional lipoma, fibrolipoma of the tongue is a very rare lesion that accounts for around 25–40% of tongue lipomas, and until now, to the best of our knowledge, only 14 cases have been described in which histological diagnosis of fibrolipoma was specifically confirmed. We report the case of a patient with a voluminous fibrolipoma of the tongue, treated by means of surgical excision. Fibrolipoma excision, like that described in this report, sometimes may be laborious, because fibrous bands appear to be focally infiltrating adjacent tissues, giving rise to some doubts about the nature of the lesion. Case presentation: We report the case of a voluminous fibrolipoma of the tongue in a 71-year-old Caucasian woman. Conclusions: Because of its histological characteristics, abundance of connective and secondary changes/atrophy, fibrolipoma may appear as infiltrating adjacent tissues and may cause doubts of differential diagnosis with malignant infiltrating lesions. Surgical excision is the elective treatment. However, an accurate differential diagnosis, postsurgical histological examination and careful follow-up are required. [ABSTRACT FROM AUTHOR]

Introduction Myxofibrosarcoma is the most common soft tissue sarcoma that occurs in late adult life, peaking in the seventh decade, and it is mainly encountered in the lower extremities. Myxofibrosarcoma of the head and neck are extremely rare. To the best of our knowledge, only 19 cases have been described in the head and neck so far. This is a literature review and retrospective chart review of our experience in head and neck myxofibrosarcoma treatment in our department. Case presentation In this case report we describe a 35-year-old Caucasian man who presented the first case of myxofibrosarcoma arising from the pterygopalatine fossa. The peculiar anatomical location and the extent in the midcheek region make this case a hard "challenge" for the surgeon, in order to guarantee wide surgical margins of resection. A total right maxillectomy was accomplished by means of the Weber-Ferguson approach, preserving the orbital floor. The excised portion was reconstructed using the free rectus abdominis myocutaneous flap. Postoperative radiotherapy was given to the area adjacent to the lesion, with a total dose of 60Gy. No relapse occurred in the 27-month postoperative follow-up. Conclusions The case described suggests the importance of combined surgical and adjuvant radiotherapy to avoid local and distant recurrences of the tumor. In our opinion, combined surgical and adjuvant radiotherapy followed by close clinical observation to search for a metastatic disease is advisable in all cases. Further studies are needed to confirm the efficacy of combined radio-chemotherapy for head and neck myxofibrosarcoma in terms of long-term disease-free survival. [ABSTRACT FROM AUTHOR]

In this work, a novel concept is introduced in drug-eluting fibres to ensure a good control of drug delivery features and wide applicability to different bioactive compounds. Composite bioactive sutures based on fibre grade poly(ε-caprolactone) (PCL) and loaded with the anti-inflammatory drug Diclofenac (Dic) or a Dic nanohybrid where the drug is intercalated in a synthetic hydrotalcite (Mg/Al hydroxycarbonate) (HT–Dic) were developed. Fibres were prepared by melt-spinning at different PCL/HT–Dic/Dic ratios and analysed in terms of morphology, mechanical properties and drug release features. Results emphasized that tensile properties of fibres are clearly affected by Dic or HT–Dic addition, while the presence of knots has limited influence on the mechanical behaviour of the sutures. Release of Dic strongly depends on how Dic is loaded in the fibre (as free or nanohybrid) whereas the combination of free Dic and HT–Dic can allow a further tuning of release profile. In vivo experiments show a reduction of inflammatory responses associated with Dic-loaded fibers. Thus, a proof of principle is provided for a novel class of bioactive sutures integrating advanced controlled-release technologies. [ABSTRACT FROM AUTHOR]

Background. Among patients with diagnosis of Laryngeal Squamous Cell Carcinoma (LSCC), up to 37.5% of cases may have occult metastasis (OM), and this feature is linked to poor prognosis and high rate of local recurrence. The role of elective neck dissection (END) in clinically negative neck (cN0) LSCC remains controversial. It is of great value to search for low-cost and easily detectable indicators to predict the risk of OM in laryngeal cancer. Recent reports have shown that high values of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) represent a negative prognostic factor in head and neck cancers. The aim of our study has been to investigate the value of pre-treatment NLR and PLR with regard to predicting occult cervical metastasis in cN0 supraglottic and glottic LSCC. Materials and methods. Data of patients affected by LSCC, who had been surgically treated by means of laryngectomy (total, horizontal partial and supracricoid) and END between January 2006 and January 2021, were retrospectively reviewed, using information retrieved from a database dedicated to such procedures in a single tertiary care referral institute. Results. A total of 387 patients were treated for LSCC at our Institute from 2006 to 2021, but only 108 of them met the inclusion criteria. The median age at the time of diagnosis was 64 years (range, 39–89 years). All the tumors were treated with a laryngectomy and an END. A total of 27.7% of patients were found positive for neck node metastasis (the pN+ group), while 78/108 (72.3%) patients were found to be negative for the presence of neck metastasis (the pN0 group). High values of NLR, but not PLR, significantly correlated with the probability of OM, and according to the iterative algorithm of Newton–Raphson, an NLR value of 2.26 corresponds to a probability of OM of 20%. Conclusion. Our analysis revealed a statistical correlation between high NLR pre-treatment values and positive neck OM in patients with LSCC. [ABSTRACT FROM AUTHOR]

CELL proliferation , *BENZOPYRANS , *MACHINE learning - Abstract
We introduce a machine learning-based analysis to predict the immunohistochemical (IHC) labeling index for the cell proliferation marker Ki67/MIB1 on cancer tissues based on morphometrical features extracted from hematoxylin and eosin (H&E)-stained formalin-fixed, paraffin-embedded (FFPE) tumor tissue samples. We provided a proof-of-concept prediction of the Ki67/MIB1 IHC positivity of cancer cells through the definition and quantitation of single nuclear features. In the first instance, we set our digital framework on Ki67/MIB1-stained OSCC (oral squamous cell carcinoma) tissue sample whole slide images, using QuPath as a working platform and its integrated algorithms, and we built a classifier in order to distinguish tumor and stroma classes and, within them, Ki67-positive and Ki67-negative cells; then, we sorted the morphometric features of tumor cells related to their Ki67 IHC status. Among the evaluated features, nuclear hematoxylin mean optical density (NHMOD) presented as the best one to distinguish Ki67/MIB1 positive from negative cells. We confirmed our findings in a single-cell level analysis of H&E staining on Ki67-immunostained/H&E-decolored tissue samples. Finally, we tested our digital framework on a case series of oral squamous cell carcinomas (OSCC), arranged in tissue microarrays; we selected two consecutive sections of each OSCC FFPE TMA (tissue microarray) block, respectively stained with H&E and immuno-stained for Ki67/MIB1. We automatically detected tumor cells in H&E slides and generated a "false color map" (FCM) based on NHMOD through the QuPath measurements map tool. FCM nearly coincided with the actual immunohistochemical result, allowing the prediction of Ki67/MIB1 positive cells in a direct visual fashion. Our proposed approach provides the pathologist with a fast method of identifying the proliferating compartment of the tumor through a quantitative assessment of the nuclear features on H&E slides, readily appreciable by visual inspection. Although this technique needs to be fine-tuned and tested on larger series of tumors, the digital analysis approach appears to be a promising tool to quickly forecast the tumor's proliferation fraction directly on routinely H&E-stained digital sections.
