Abstract
OBJECTIVE We aimed to describe characteristics of patients with ATTR variant polyneuropathy (ATTRv-PN) and ATTRv-mixed and assess the real-world use and safety profile of tafamidis meglumine 20mg. METHODS Thirty-eight French hospitals were invited. Patient files were reviewed to identify clinical manifestations, diagnostic methods, and treatment compliance. RESULTS Four hundred and thirteen patients (296 ATTRv-PN, 117 ATTRv-mixed) were analyzed. Patients were predominantly male (68.0%) with a mean age of 57.2±17.2 years. Interval between first symptom(s) and diagnosis was 3.4±4.3 years. First symptoms included sensory complaints (85.9%), dysautonomia (38.5%), motor deficits (26.4%), carpal tunnel syndrome (31.5%), shortness of breath (13.3%), and unexplained weight loss (16.0%). Mini-invasive accessory salivary gland or punch skin and nerve biopsies were most common, with a performance of 78.8-100%. TTR genetic sequencing, performed in all patients, revealed 31 TTR variants. Tafamidis meglumine was initiated in 156/214 (72.9%) ATTRv-PN patients at an early disease stage. Median treatment duration was 6.00 years in ATTRv-PN and 3.42 years in ATTRv-mixed patients. Tafamidis was well tolerated, with 20 adverse events likely related to study drug among the 336 patients. CONCLUSION In France, ATTRv patients are usually identified early thanks to the national network and the help of diagnosis combining genetic testing and mini-invasive biopsies.

Abstract
OBJECTIVES To analyze the perception of endoscopic endonasal surgery training by French otolaryngology residents. MATERIAL AND METHODS A multicenter retrospective observational study was conducted from March to April 2023. Otolaryngology residents from 7 French regions filled out a 27-item questionnaire on their training in endoscopic endonasal surgery. RESULTS Out of 283 residents contacted, 126 (45%) filled out the questionnaire. Seventy-four (59%) had already partially or completely performed the surgeries specified in their diploma course. The level of mastery of the main steps of endonasal surgery and the level of autonomy were higher in the consolidation stage group than in the basic and advanced stages. Seventy residents (56%) felt they had gaps in their level of training. To improve training, 94 (75%) wished for more dissection sessions, surgical skills assessments each semester and simulation sessions. Eighty-nine (71%) felt they needed to find their own teaching aids and other methods to complete their training. One hundred and thirteen (90%) felt that the lack of funding available for congresses and training courses was detrimental. CONCLUSION This study highlighted the overall satisfaction of residents with their training in endoscopic endonasal surgery. They expressed a desire for more dissection, simulation and evaluation.

Abstract
OBJECTIVE To evaluate the impact of the first three waves of COVID-19 on the academic and surgical training of ENT and Head and Neck Surgery residents in France. MATERIAL AND METHODS Observational, retrospective study. A 55-item survey of academic education and surgical training was sent to ENT residents in five major French regions (Île-de-France, Rhône-Alpes Auvergne, Occitanie, Grand Est, Grand Ouest) from August to October 2021. RESULTS Eighty-nine out of 135 residents (66%) responded. Two-thirds considered that surgical training was more affected than academic education, with reductions evaluated of 50-75%, 25-50% and 0-25% for the first three waves, respectively. Residents in Île-de-France, Rhône-Alpes Auvergne and Grand Est were the most affected by the first wave (75-100% reduction in surgical activity, in parallel to increased admissions). Otology, rhinology and functional exploration were the most affected, whereas pediatrics and oncology were spared. Seventy-one of the 89 residents (79.7%) felt that the first wave impacted their career, while this proportion decreased to 39.3% and 44.9% for the second and third waves, respectively. CONCLUSION The first wave of COVID-19, compared to the following two waves, severely impacted the surgical training of French ENT residents, especially in regions severely impacted by the pandemic, while academic education was relatively safeguarded by the implementation of e-learning alternatives.

Abstract
OBJECTIVES To assess the morbidity specific of extended pelvic lymphadenectomy during robot-assisted laparoscopic radical prostatectomy in a 8 year retrospective study. MATERIAL We carried out a single-center, single-surgeon retrospective study on 342 consecutive patients who underwent a robot-assisted laparoscopic radical prostatectomy and extended pelvic lymphadenectomy, from July 2010 to March 2018. Postoperative complications were recorded up to 3 months after the operation. RESULTS Thirty (8.8%) patients had at least one complication related to lymphadenectomy including 1 vascular injury (0.3%), 7 injuries of the obturator nerve (2%), 5 venous thromboembolic complications (1.5%) including 4 pulmonary embolisms, 10 symptomatic lymphoceles (2.9%) and 8 lymphoedemas (2.3%). Of these complications, 13 were classified Clavien 1 (43.3%), 8 Clavien 2 (26.7%), 7 Clavien 3a (23.3%) and 2 Clavien 3b (6.7%). In univariate analysis a high age (P=0.04), high BMI (P<0.01) and pT stage (P=0.02) were significantly associated with complication whereas in multivariate analysis, only age (P=0.02) and BMI (P<0.01) lived were. In univariate analysis high BMI (P=0.04) and lymph node involvement (P=0.04) were associated with lymphatic complication. We did not find any other specific risk factor for the other complications. CONCLUSION With 8.8% of overall complications related to lymphadenectomy and 5% of complication classified Clavien grade 2 or higher, extended pelvic lymphadenectomy was not very morbid. Age and BMI were risk factors for a overall complication. BMI and lymph node involvement were risk factors for lymphatic complications. LEVEL OF PROOF 4.

Abstract
Metastases are initiated by disseminated tumor cells (DTCs) that colonize distant organs. Growing evidence suggests that the microenvironment of the primary tumor primes DTCs for dormant or proliferative fates. However, the manner in which this occurs remains poorly understood. Here, using the Window for High-Resolution Intravital Imaging of the Lung (WHRIL), we study the live lung longitudinally and follow the fate of individual DTCs that spontaneously disseminate from orthotopic breast tumors. We find that spontaneously DTCs have increased levels of retention, increased speed of extravasation, and greater survival after extravasation, compared to experimentally metastasized tumor cells. Detailed analysis reveals that a subset of macrophages within the primary tumor induces a pro-dissemination and pro-dormancy DTC phenotype. Our work provides insight into how specific primary tumor microenvironments prime a subpopulation of cells for expression of proteins associated with dissemination and dormancy.

Abstract
Cancer stem cells (CSCs) play an important role during metastasis, but the dynamic behavior and induction mechanisms of CSCs are not well understood. Here, we employ high-resolution intravital microscopy using a CSC biosensor to directly observe CSCs in live mice with mammary tumors. CSCs display the slow-migratory, invadopod-rich phenotype that is the hallmark of disseminating tumor cells. CSCs are enriched near macrophages, particularly near macrophage-containing intravasation sites called Tumor Microenvironment of Metastasis (TMEM) doorways. Substantial enrichment of CSCs occurs on association with TMEM doorways, contributing to the finding that CSCs represent >60% of circulating tumor cells. Mechanistically, stemness is induced in non-stem cancer cells upon their direct contact with macrophages via Notch-Jagged signaling. In breast cancers from patients, the density of TMEM doorways correlates with the proportion of cancer cells expressing stem cell markers, indicating that in human breast cancer TMEM doorways are not only cancer cell intravasation portals but also CSC programming sites.

Abstract
Metastasis, accounting for ~90% of cancer-related mortality, involves the systemic spread of cancer cells from primary tumors to secondary sites such as the bone, brain, and lung. Although extensively studied, the mechanistic details of this process remain poorly understood. While common imaging modalities, including computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI), offer varying degrees of gross visualization, each lacks the temporal and spatial resolution necessary to detect the dynamics of individual tumor cells. To address this, numerous techniques have been described for intravital imaging of common metastatic sites. Of these sites, the lung has proven especially challenging to access for intravital imaging owing to its delicacy and critical role in sustaining life. Although several approaches have previously been described for single-cell intravital imaging of the intact lung, all involve highly invasive and terminal procedures, limiting the maximum possible imaging duration to 6-12 h. Described here is an improved technique for the permanent implantation of a minimally invasive thoracic optical Window for High-Resolution Imaging of the Lung (WHRIL). Combined with an adapted approach to microcartography, the innovative optical window facilitates serial intravital imaging of the intact lung at single-cell resolution across multiple imaging sessions and spanning multiple weeks. Given the unprecedented duration of time over which imaging data can be gathered, the WHRIL can facilitate the accelerated discovery of the dynamic mechanisms underlying metastatic progression and numerous additional biologic processes within the lung.

Abstract
Background The COVID-19 pandemic has had a major impact on healthcare in many countries. This study assessed the effect of a nationwide lockdown in France on admissions for acute surgical conditions and the subsequent impact on postoperative mortality. Methods This was an observational analytical study, evaluating data from a national discharge database that collected all discharge reports from any hospital in France. All adult patients admitted through the emergency department and requiring a surgical treatment between 17 March and 11 May 2020, and the equivalent period in 2019 were included. The primary outcome was the change in number of hospital admissions for acute surgical conditions. Mortality was assessed in the matched population, and stratified by region. Results During the lockdown period, 57 589 consecutive patients were admitted for acute surgical conditions, representing a decrease of 20.9 per cent compared with the 2019 cohort. Significant differences between regions were observed: the decrease was 15.6, 17.2, and 26.8 per cent for low-, intermediate- and high-prevalence regions respectively. The mortality rate was 1.92 per cent during the lockdown period and 1.81 per cent in 2019. In high-prevalence zones, mortality was significantly increased (odds ratio 1.22, 95 per cent c.i. 1.06 to 1.40). Conclusion A marked decrease in hospital admissions for surgical emergencies was observed during the lockdown period, with increased mortality in regions with a higher prevalence of COVID-19 infection. Health authorities should use these findings to preserve quality of care and deliver appropriate messages to the population.

Abstract
Objective To analyse tracheostomies after intubation for SARS-Cov-2 infection performed by otorhinolaryngologists in 7 university hospitals in the Paris area of France during the month March 24 to April 23, 2020. Material and methods A multicentre retrospective observational study included 59 consecutive patients. The main goals were to evaluate the number, characteristics and practical conditions of tracheostomies, and the COVID-19 status of the otorhinolaryngologists. Secondary goals were to analyse tracheostomy time, decannulation rate, immediate postoperative complications and laryngotracheal axis status. Results Tracheostomy indications were for ventilatory weaning and extubation failure in 86% and 14% of cases, respectively. The technique was surgical, percutaneous or hybrid in 91.5%, 3.4% and 5.1% of cases, respectively. None of the operators developed symptoms consistent with COVID-19. Postoperative complications occurred in 15% of cases, with no significant difference between surgical and percutaneous/hybrid techniques (P = 0.33), although no complications occurred after percutaneous or hybrid tracheostomies. No procedures or complications resulted in death. The decannulation rate was 74.5% with a mean tracheostomy time of 20 ± 12 days. In 55% of the patients evaluated by flexible endoscopy after decannulation, a laryngeal abnormality was found. On univariate analysis, no clinical features had a significant influence on tracheostomy time, decannulation rate or occurrence of laryngeal lesions. Conclusion The main findings of the present retrospective study were: absence of contamination of the surgeons, heterogeneity of practices between centres, a high rate of complications and laryngeal lesions whatever the technique, and the specificities of the patients.

Abstract
BACKGROUND Sports concussion is a major problem that affects thousands of people every year. Concussion-related neurometabolic changes are thought to underlie neurophysiological alterations and post-concussion symptoms, such as headaches and sensitivity to light and noise, disabilities of concentration and tiredness. The injury triggers a complex neurometabolic cascade involving multiple mechanisms. There are pharmaceutical treatments that target one mechanism, but specific nutrients have been found to impact several pathways, thus offering a broader approach. This has prompted intensive research into the use of nutrient supplements as a concussion prevention and treatment strategy. METHOD We realised a bibliographic state of art providing a contemporary clinical and preclinical studies dealing with nutritional factors in sport-related concussion. RESULTS Numerous supplements, including n-3 polyunsaturated fatty acids, sulfur amino acids, antioxidants and minerals, have shown promising results as aids to concussion recovery or prevention in animal studies, most of which use a fluid percussion technique to cause brain injury, and in a few human studies of severe or moderate traumatic brain injury. Current ongoing human trials can hopefully provide us with more information, in particular, on new options, i.e. probiotics, lactate or amino acids, for the use of nutritional supplements for concussed athletes. CONCLUSION Nutritional supplementation has emerged as a potential strategy to prevent and/or reduce the deleterious effects of sports-related concussion and subconcussive impacts.

Abstract
INTRODUCTION Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the categories of chronic rhinosinusitis and is defined by the presence of bilateral polyps. It is frequently associated with other conditions (asthma, atopy, aspirin intolerance), which worsen its prognosis. STATE OF ART The pathophysiology of CRSwNP is still poorly understood. The genesis of polyps is thought to be based on an initial epithelial lesion caused by environmental factors in the context of self-maintained chronic local inflammation. Multiple local and general factors can be involved in this inflammation, which is mainly of Th2 type in Europe. Abnormalities of the epithelial barrier and the immune system (eosinophilia, cytokines, T and B lymphocytes), genetic factors and pathogens, including Staphylococcus aureus, have been incriminated. The treatment of CRSwNP is mainly based on the application of local corticosteroids. Surgery remains an important part of patient management where CRSwNP becomes resistant to topical therapy. The management of CRSwNP may be at a turning point thanks to the arrival of biological therapies (anti-IgE, anti-IL-5, anti-IL-4/IL-13) the initial results of which are promising. PERSPECTIVES/CONCLUSIONS With the new concept of endotypes, current avenues of research are moving towards a better understanding of the inflammatory mechanisms of CRSwNP. Immunotherapy appears to be a promising future for the treatment of CRSwNP.

Abstract
BACKGROUND Mild traumatic brain injury (mTBI) is one of the most common causes of emergency department visits around the world. Up to 90% of injuries are classified as mTBI. Cranial computed tomography (CCT) is a standard diagnosis tool to identify intracranial complications in adults with mTBI. Alternatively, children can be admitted for inpatient observation with CCT scans performed only on those with clinical deterioration. The use of blood biomarkers is a supplementary tool for identifying patients at risk of intracerebral lesions who may need imaging. METHOD We realised a bibliographic state of art providing a contemporary clinical and laboratory framework for blood biomarker testing in mTBI management. RESULTS The S100B protein is the only biomarker that can be used today in the clinical routine for management of mTBI with appropriate evidence-based medicine. Due to its excellent negative predictive value, S100B protein is an alternative choice to CCT scanning for mTBI management with considered, consensual and pragmatic use. In this state of art, we propose points to help clinicians and clinical pathologists use serum S100B protein in the clinical routine. A state of art on the different biomarkers (GFAP, UCH-L1, NF [H or L], tau, H-FABP, SNTF, NSE, miRNAs, MBP) is also conducted. Some of these other biomarkers, used alone (GFAP, UCH-L1) or in combination (GFAP+H-FABP±S100B±IL10) can improve the specificity of S100B. CONCLUSION Using a bibliographic state of art, we highlighted the added values of the blood biomarkers for the clinical management of mTBI.

Abstract
The present article reviews the molecular and cellular mechanisms involved in the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwCRSwNP) and underlying the action mechanisms of biotherapies. Biotherapy uses substances naturally produced by the organism or their specific antagonists targeting a proinflammatory mechanism. CRSwCRSwNP is a form of chronic rhinosinusitis (CRS), which is classically subdivided in to 2 types according to the presence of polyps. In recent years, the concept of endotypes emerged, with a more exhaustive definition of the types of CRS according to inflammatory mechanism, with a view to developing personalized treatments. CRSwNP pathophysiology is poorly understood. Polyps arise from a primary epithelial lesion in a context of chronic local inflammation, mainly type 2 in Europe, implicating eosinophils, IgE, Th2 cytokines (IL-4/IL-13, IL-5) and T and B cells. Biotherapy seems promising in CRSwNP. The present review details the various pathophysiological pathways underlying the action mechanisms of biotherapies, and the various published studies, assessing efficacy and mode of action in the treatment of CRSwNP.

Abstract
In primary breast tumors, cancer cells hematogenously disseminate through doorways in the vasculature composed of three-cell complexes (known as Tumor MicroEnvironment of Metastasis) comprising a perivascular macrophage, a tumor cell overexpressing the actin-regulatory protein Mammalian Enabled (Mena), and an endothelial cell, all in direct physical contact. It has been previously shown that once tumor cells establish lymph node metastases in patients, TMEM doorways form in the metastatic tumor cell nests. However, it has not been established if such lymph node-TMEM doorways actively transit tumor cells into the peripheral circulation and on to tertiary sites. To address this question in this short report, we used a mouse model of lymph node metastasis to demonstrate that TMEM doorways: (1) exist in tumor-positive lymph nodes of mice, (2) are restricted to the blood vascular endothelium, (3) serve as a mechanism for further dissemination to peripheral sites such as to the lungs, and (4) their activity can be abrogated by a pharmaceutical intervention. Our data suggest that cancer cell dissemination via TMEM doorways is a common mechanism of breast cancer cell dissemination to distant sites and thus the pharmacological targeting of TMEM may be necessary, even after resection of the primary tumor, to suppress cancer cell dissemination.

Abstract
Genetically engineered and orthotopic xenograft mouse models have been instrumental for increasing our understanding of thyroid cancer progression and for the development of novel therapeutic approaches in a setting that is more physiologically relevant than the classical subcutaneous flank implants. However, the anatomical location of the thyroid gland precludes a non-invasive analysis at the cellular level of the interactions between tumor cells and the surrounding microenvironment and does not allow a real-time evaluation of the response of tumor cells to drug treatments. As a consequence, such studies have generally only relied on endpoint approaches, limiting the amount and depth of the information that could be gathered. Here we describe the development of an innovative approach to imaging specific aspects of thyroid cancer biology, based on the implantation of a permanent, minimally invasive optical window that allows high-resolution, multi-day, intravital imaging of the behavior and cellular dynamics of thyroid tumors in the mouse. We show that this technology allows visualization of fluorescently tagged tumor cells both in immunocompetent, genetically engineered mouse models of anaplastic thyroid cancer (ATC) and in immunocompromised mice carrying orthotopic implanted human or mouse ATC cells. Furthermore, the use of recipient mice in which endothelial cells and macrophages are fluorescently labeled allows the detection of the spatial and functional relationship between tumor cells and their microenvironment. Finally, we show that ATC cells expressing a fluorescent biosensor for caspase 3 activity can be effectively utilized to evaluate, in real-time, the efficacy and kinetics of action of novel small molecule therapeutics. This novel approach to intravital imaging of thyroid cancer represents a platform that will allow, for the first time, the longitudinal, in situ analysis of tumor cell responses to therapy and of their interaction with the microenvironment.

Abstract
Abstract
Background: Cancer stem cells (CSCs) play an important role during metastatic progression of breast cancer. However, little is known, at the single cell level, about the process of stemness induction in non-stem cells or the dynamic behavior of CSCs during hematogenous dissemination.
Methods: Here, we employed high-resolution intravital multiphoton microscopy with a SOX2/OCT4 responsive fluorescent biosensor for stemness to directly observe the induction of stemness in single non-stem cells and their evolution through the metastatic cascade in living animals using orthotopic breast cancer xenograft model. We confirmed our findings in vitro using tumor cell-macrophage co-culture assays.
Results: We report that, both in vitro and in vivo, direct physical contact with macrophages induces stemness in non-stem cancer cells via juxtacrine Notch-Jagged1 signaling. In vivo, macrophage depletion with clodronate treatment showed a significant decrease in stem cells. In vitro, using either the fate mapping of non-stem cells with or without macrophage contact, or the origin-mapping of stem cells to find whether they originated from non-stem cells or pre-existing stem cells, we found that there was four-fold increase in new CSC induction after direct macrophage contact. In contrast, we did not see any role of macrophages in the expansion of pre-existing CSCs, both in vivo and in vitro, indicating that macrophage contact-dependent stem induction is the primary mechanism of CSC generation.
Using immunohistochemical staining in fixed tissue and live imaging of primary tumors and lungs in mice using optical windows, we found that during the course of dissemination of tumor cells from the primary site, CSCs become progressively enriched in the tumor cell population as they approach dissemination doorways (known as TMEM, Tumor MicroEnvironment of Metastasis), intravasate, circulate and arrive at the lung. Association with and passage through TMEM doorways is the step that generates the greatest enrichment in CSCs (~ 60-fold). On arrival in the lung, CSCs represent more than 75% of the disseminated tumor cell population, greatly enriched compared with their representation in the bulk primary tumor of ~ 1%.
Conclusion: Overall, these data indicate, for the first time, that macrophages associated with TMEM induce CSCs and promote TMEM-mediated CSC intravasation and early metastatic seeding. Our results are consistent with the dramatic enrichment of cancer stem cell markers in association with TMEM in breast cancer patients (Kim et al 2020 AACR abstract) and support a strategy for anti-metastatic therapy.

Abstract
Metastasis, a process that requires tumor cell dissemination followed by tumor growth, is the primary cause of death in cancer patients. An essential step of tumor cell dissemination is intravasation, a process by which tumor cells cross the blood vessel endothelium and disseminate to distant sites. Studying this process is of utmost importance given that intravasation in the primary tumor, as well as the secondary and tertiary metastases, is the key step in the systemic spread of tumor cells, and that this process continues even after removal of the primary tumor. High-resolution intravital imaging of the tumor microenvironment of breast carcinoma has revealed that tumor cell intravasation exclusively occurs at doorways, termed "Tumor MicroEnvironment of Metastasis" (TMEM), composed of three different cell types: a Tie2high/VEGFhigh perivascular macrophage, a Mena overexpressing tumor cell, and an endothelial cell, all in direct contact. In this review article, we discuss the interactions between these cell types, the subsequent signaling events which lead to tumor cell intravasation, and the role of invadopodia in supporting tumor cell invasion and dissemination. We end our review by discussing how the knowledge acquired from the use of intravital imaging is now leading to new clinical trials targeting tumor cell dissemination and preventing metastatic progression.

Abstract
OBJECTIVE To evaluate the impact of the first month of lockdown related to the Covid-19 epidemic on the oncologic surgical activity in the Ile de France region university hospital otorhinolaryngology departments. MATERIAL AND METHODS A multicenter prospective observational assessment was conducted in 6 university hospital otorhinolaryngology departments (Paris Centre, Nord, Est and Sorbonne) during the 1-month periods before (Month A) and after (Month B) lockdown on March 17, 2020. The main goal was to evaluate lockdown impact on oncologic surgical activity in the departments. Secondary goals were to report population characteristics, surgery conditions, postoperative course, progression of Covid status in patients and surgeons, and adverse events. RESULTS 224 procedures were performed. There was 10.9% reduction in overall activity, without significant difference between departments. Squamous cell carcinoma and larynx, hypopharynx, oropharynx, oral cavity and nasal cavity and sinus locations were predominant, at 79% and 75.8% of cases respectively, with no significant differences between months. T3/4 and N2/3 tumors were more frequent in Month B (P=.002 and .0004). There was no significant difference between months regarding surgical approach, type of reconstruction, postoperative course, tracheotomy and nasogastric feeding-tube time, intensive care stay or hospital stay. None of the Month A patients were Covid-19-positive, versus 3 in Month B, without adverse events. None of the otorhinolaryngologists involved in the procedures developed symptoms suggesting Covid-19 infestation. CONCLUSION The present study underscored the limited impact of the Covid-19 epidemic and lockdown on surgical diagnosis and cancer surgery in the Ile de France university otorhinolaryngology departments, maintaining chances for optimal survival without spreading the virus.

Abstract
In Otorhinolaryngology – Head and Neck Surgery, clinical examination and invasive procedures on the respiratory tract and on airway-connected cavities, such as paranasal sinuses and the middle ear, expose people to direct transmission of SARS-CoV-2 by inhalation or ocular projection of contaminated droplets, and to indirect transmission by contact with contaminated hands, objects or surfaces. Estimating an R0 of COVID-19 at around 3 justified postponing non-urgent face-to-face consultations and expanding the use of teleconsultation in order to limit the risks of SARS-CoV-2 infection of patients or health workers and comply with the lockdown. The health authority recommends cancellation of all medical or surgical activities, which are not urgent as long as this does not involve a loss of chance for the patient. The purpose of this cancellation is to significantly increase critical care capacity, prioritise the reception of patients with COVID-19, prioritise the allocation of staff and provision of the equipment necessary for their medical or surgical management, and contribute to the smooth running of downstream critical care within their establishment. Another goal is to reduce the risks of patient contamination within healthcare facilities. This document provides guidance on how to proceed with and adapt ENT surgery in the current pandemic context, as well as on the management of postponed operations. This best practice advice must of course be adapted in each region according to the development of the epidemic and pre-existing arrangements. Their local application can only be decided within the framework of collaboration between the ENT teams, the operational hygiene units and all the other specialties concerned.

Abstract
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is a rising cause of skin and soft tissue infections over the last decade with potentially serious complications. In this article, we describe a case of a large scalp and post-auricular abscess complicated by bacteremia. This is a case of a 73-year-old female who presented with altered mental status was found to have two fluctuant scalp abscesses, bacteremia with necrosis. The patient was promptly treated with intravenous antibiotics, multiple operative debridements without calvarial periosteum involvement defects requiring split-thickness skin grafts for wound closure. This case highlights the severity of a CA-MRSA skin infection in an atypical location.

Abstract
The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included. The full document can be downloaded for free on the website of this journal: http://www.rhinologyjournal.com.

Abstract
OBJECTIVES We aimed to evaluate the probability to achieve PK-PD targets in patients with sepsis hospitalized in the intensive care unit (ICU) after a single dose of 30mg/kg of amikacin or 8mg/kg of gentamicin. PATIENTS AND METHODS This single-center prospective study included 138 ICU patients with severe sepsis or septic shock with an indication for intravenous amikacin (N=89) or gentamicin (N=49). Maximum concentration (Cmax) was measured 30 minutes after infusion completion. PK/PD objectives were respectively Cmax≥60mg/L and ≥30mg/L for amikacin and gentamicin for empirical therapy, and a Cmax/MIC ratio≥8, as per French guidelines. RESULTS The median Simplified Acute Physiology Score II was 43 and ICU case fatality rate was 34.8%. A causative bacterial agent was identified in 94 patients (68.1%). Three pathogens had acquired aminoglycoside resistance and 15 were naturally resistant. The targeted Cmax for the first dose was achieved in 53 patients (59.6%) receiving amikacin, and one (2.2%) patient receiving gentamicin. Cmax/MIC ratio≥8 was obtained in all patients infected with susceptible pathogens (N=72). Factors associated with Cmax≥60mg/L of amikacin in multivariate analysis were dose per kg of adapted body weight (OR=1.39, P<0.001) and renal clearance estimated with CKD-EPI formula (OR=0.98, P=0.003). CONCLUSIONS Despite high doses, amikacin and gentamicin first Cmax remain dramatically low in ICU patients. However, an adequate Cmax/MIC ratio was reached in all patients.

Abstract
Intravital imaging, the direct visualization of cells and tissues within a living animal, is a technique that has been employed for the better part of a century. The advent of confocal and multiphoton microscopy has dramatically improved the power of intravital imaging, making it possible to obtain optical sections of tissues non-destructively. This review discusses the various techniques used for intravital imaging, describes how intravital imaging provides information about cellular and tissue dynamics not possible to be garnered by other techniques, and details several ways in which intravital imaging is making a direct impact on the clinical care of patients. © 2019 International Society for Advancement of Cytometry.

Abstract
Abstract
Metastatic dissemination is the major cause of cancer mortality and is responsible for over 1/2 million deaths each year in the U.S. alone. Over the past decades, metastasis has been speculated to be an inefficient process, as the majority of disseminated tumor cells (DTCs) are not believed to complete all the steps of the metastatic cascade. This conclusion has been reached by studies in which TCs are intravenously injected in mice - a process called experimental metastasis (EM) - and then attempt to quantify the number of disseminated cells in the lung over time using low resolution and indirect methods. To date, very little is known about the efficiency of each step in metastatic cascade due to the inability to track metastatic cancer cells in an intact organ over time.
Using a new cutting-edge technology, the Window for High Resolution Imaging of the Lung1, we are able for the first time to (1) track in real-time the fate of each DTC and (2) quantitatively assess the efficiency of each step of the metastatic cascade in the lung, from DTC arrival and retention in the lung vasculature, extravasation, interaction with the host microenvironment, survival, dormancy, to growth into micro-metastases. All steps are studied at single-cell resolution, longitudinally, in the same animal, and using the EM model as well as a more clinically relevant model called Spontaneous Metastasis (SM) in which tumor cells spontaneously disseminate from an orthotopic primary tumor.
A comparative analysis of the two models (EM vs. SM) demonstrated that DTCs in SM have a drastically increased metastatic efficiency compared to DTCs in EM. In particular, we found that DTCs are retained in the lung 10-times more efficiently compared to EM (62% vs. 6%). We further observe that in SM, DTCs extravasate in the lung very rapidly compared to EM (8 hrs vs. 24 hrs) and that the vast majority of DTCs after extravasation died in EM compared to SM where DTCs are dormant and express a stem-like phenotype. These data indicate that dissemination is indeed a very efficient process, but that growth at the secondary site is a rate-limiting step in the SM model.
In conclusion, the ability to observe both spontaneous and experimental metastasis, with single cell resolution, and longitudinally, has provided new insight into the efficiency of each step of the metastatic cascade in the lung. This approach additionally gives the ability to investigate the molecular mechanisms underlying seeding and dormancy of metastatic tumor cells, in the presence of the full tumor microenvironment, as well as to directly evaluate the response of disseminated tumor cells to therapeutic treatment in real time in a live mouse.

Abstract
Abstract
Cancer stem cells (CSCs) play an important role during metastatic progression of breast cancer. However, the in vivo properties and dynamic behavior of CSCs are not well understood. Here, we employed high-resolution intravital multiphoton microscopy using a SOX2/OCT4 responsive fluorescent stem cell biosensor to directly observe CSC dynamics in the living animal using an orthotopic breast cancer xenograft model. We report that CSCs constitute a minority population (1-3%) in the primary tumors, and display the slow-migratory, invasive phenotype that is specifically associated with disseminating tumor cell population. We also report, for the first time, that CSCs are preferentially localized in direct contact with macrophages near and in tumor microenvironment of metastasis (TMEM) sites, the macrophage-containing intravasation doorway for tumor cells and that CSCs metastasize to lung and are strikingly enriched in early lung metastatic colonies. This is explained by our observation that, in vitro and in vivo, direct physical contact with macrophages induces stemness in non-stem cancer cells via juxtacrine Notch-Jagged1 signaling. These data indicate for the first time that macrophages play an actively inductive role in the CSC niche and promote TMEM-mediated CSC intravasation and early metastatic seeding.

Abstract
The most common cause of cancer related mortality is metastasis, a process that requires dissemination of cancer cells from the primary tumor to secondary sites. Recently, we established that cancer cell dissemination in primary breast cancer and at metastatic sites in the lung occurs only at doorways called Tumor MicroEnvironment of Metastasis (TMEM). TMEM doorway number is prognostic for distant recurrence of metastatic disease in breast cancer patients. TMEM doorways are composed of a cancer cell which over-expresses the actin regulatory protein Mena in direct contact with a perivascular, proangiogenic macrophage which expresses high levels of TIE2 and VEGF, where both of these cells are tightly bound to a blood vessel endothelial cell. Cancer cells can intravasate through TMEM doorways due to transient vascular permeability orchestrated by the joint activity of the TMEM-associated macrophage and the TMEM-associated Mena-expressing cancer cell. In this manuscript, we describe two methods for assessment of TMEM-mediated transient vascular permeability: intravital imaging and fixed tissue immunofluorescence. Although both methods have their advantages and disadvantages, combining the two may provide the most complete analyses of TMEM-mediated vascular permeability as well as microenvironmental prerequisites for TMEM function. Since the metastatic process in breast cancer, and possibly other types of cancer, involves cancer cell dissemination via TMEM doorways, it is essential to employ well established methods for the analysis of the TMEM doorway activity. The two methods described here provide a comprehensive approach to the analysis of TMEM doorway activity, either in naïve or pharmacologically treated animals, which is of paramount importance for pre-clinical trials of agents that prevent cancer cell dissemination via TMEM.

Abstract
Allergic rhinitis is a common condition, with significant impact on quality of life depending on severity and quality of control. Allergen-specific immunotherapy (allergen-SIT) is the only known treatment able to alter the natural course of allergic rhinitis. Although well known to allergologists, it has yet to be fully adopted by the ENT community. This review, based on the most recent meta-analyses and clinical studies, shows that SIT significantly reduces symptoms and medication requirements (nasal corticosteroids, H1-antihistamines) in allergic rhinitis. It can reduce the risk of progression to asthma and, if initiated early enough, of developing new sensitizations. Immunobiological analysis shows an altered inflammatory profile following SIT, with immune tolerance involving T-regulatory lymphocyte induction and IgG production. Sublingual SIT with drops is as effective as subcutaneous SIT and is simpler to use, with less anaphylactic risk. Standardization of trial protocols in terms of treatment response assessment and side effect grading is recommended to improve comparative studies. Sublingual SIT with tablets has recently been introduced, providing a good opportunity for ENT practitioners to adopt the SIT approach in rhinitis triggered by allergy to pollens and, in the near future, to house dust mites.
