RESUMO
In response to the complexity of medical care in oncology, 2 years ago, we designed a new teaching method (SPOC, Small Private Online Course) to improve cancer treatment and its management by emphasizing the community-hospital interface. The educational objective of this study was to evaluate after 1 year if the interest for this teaching remained constant over the long term to meet both educational and financial requirements. We designed a questionnaire including 18 questions grouped in 3 main parts describing the profile of the participants, his/her own experience, and the current utilization of the SPOC. Of 1574 participants of the 2 first sessions, 182 (11.5%) completed the questionnaire after 1 year. The majority of respondents were between the ages of 31 and 60 and belonged to a paramedical group (47.81%). After 1 year, 84.6% participants were satisfied or very satisfied with the content of the SPOC, 83.6% would recommended it, and 67% would be interested in using an updated SPOC again. Only 4.9% kept some contacts with other participants and 4.9% with teachers. 31.3% considered that the SPOC had a medium impact on their professional activity, 33.5% a lot, and 2.7% completely whereas 24.7% considered that it had little impact. The evaluation at 1 year showed that this digital learning method had a global positive impact on the professional practice of the participants. This study highlighted the empowerment of participants after this kind of teaching, but the network between participants was not enhanced.

OBJECTIVES: Trans-nasal endoscopic sphenopalatine artery ligation (TESPAL) and endovascular arterial embolisation both provide excellent success rates for intractable epistaxis. Recent economic models suggest that TESPAL could be a cost-saving strategy. Our main aim was to perform cost-effectiveness analyses on TESPAL compared with embolisation to treat patients with epistaxis. DESIGN: We performed retrospective, monocentric, comparative analyses on patients referred to our centre and treated with embolisation or TESPAL. SETTING: This economic evaluation was carried out from a payer's perspective (ie French National Health Insurance) within a time horizon of 12 months. PARTICIPANTS: Thirty-seven TESPAL procedures and thirty-nine embolisation procedures to treat intractable epistaxis were used in the analyses. MAIN OUTCOME MEASURES: The primary outcome is presented as the cost per 1% of non-recurrence. Effectiveness was defined as avoiding recurrence of epistaxis during the 1-year follow-up. Cost estimates were performed from the payer's perspective. RESULTS: Hospitalisation costs were higher for embolisation compared with TESPAL (5972 vs 3769 euros). On average, hospitalisation costs decreased by 41% when a patient was treated by TESPAL compared with an embolisation strategy (P = 0.06). The presence of comorbidities increased hospitalisation costs by 79% (P = 0.04). TESPAL enabled 1867 to be gained in intractable epistaxis. CONCLUSIONS: The outcomes from our decision model confirm that TESPAL is more cost-effective for patients with intractable epistaxis.

BACKGROUND: Mammary analog secretory carcinoma (MASC) of the salivary gland has been recently described according to morphological, immunohistochemical, and molecular (ETV6-NTRK3 translocation) similarities with the mammary secretory carcinoma. The most important differential diagnostic considerations of MASC are low-grade adenocarcinoma not otherwise specified (NOS), cystadenocarcinoma, and acinic cell carcinoma (AciCC). These tumors may share an overlapping morphology with MASC, and additional immunohistochemical studies are required to reinforce the diagnosis. Mammaglobin, GCDFP-15, and p63 staining have been reported in MASC. Our study was designed to check the specificity of these antibodies in MASC compared to other frequent tumors of salivary glands. METHODS: A series of 62 salivary gland tumors [10 MASCs, 5 adenocarcinomas NOS and 2 cystadenocarcinomas with MASC features and without ETV6 rearrangement, one low-grade cribriform cystadenocarcinoma (LGCCC), 9 AciCCs, 10 MECs, 10 adenoid cystic carcinomas (AdeCCs), 5 polymorphous low-grade adenocarcinomas (PLGAs), and 10 pleomorphic adenomas (PAs)] was analyzed by immunohistochemistry with mammaglobin, GCDFP-15, and p63 antibodies. RESULTS: Positivity for mammaglobin was observed in all MASCs, cystadenocarcinomas, LGCCC, and PLGAs, in some adenocarcinomas NOS, PAs, and MECs, rarely in AciCCs and never in AdeCCs. Positivity for GCDFP-15 was observed in most of the tumor types except in AdeCCs. Interestingly, cytoplasmic positivity for p63 was observed in most of MASCs and PLGAs while rarely in adenocarcinomas NOS and PAs, and never in the other tumor types. CONCLUSION: Our study revealed the usefulness of mammaglobin and p63 cytoplasmic staining to define which tumors are worth to be screened for ETV6 rearrangement.

Respiratory epithelial adenomatoid hamartoma (REAH) is a relatively recent diagnosis that is gaining more interest in sinus surgery. REAH of the olfactory cleft was often misdiagnosed, and interpreted as nasal polyposis (NP). We present a retrospective case series of 27 patients who were diagnosed and treated for REAH of the olfactory cleft, in the past 7 years, in our department. The aim of this study is to present the diagnostic modalities and the results and follow-up after surgery. The male to female ratio was 2.9:1, with a mean age of 56 years. Almost half of these patients were operated at least once before on their sinuses. The most common presenting symptoms of isolated REAH are olfactory disorders. All cases were treated surgically with endoscopic sinus surgery, without recurrences in the follow-up period. Knowledge and identification of REAH of the olfactory cleft are fundamental. Knowledge, identification, and adequate treatment of these lesions are fundamental, as they limit the number of recurrences.

PURPOSE: This study was designed to assess the efficacy and morbidity of the endoscopic endonasal approach for the treatment of sinonasal adenocarcinomas. METHODS: This was a retrospective, multicenter study of nine French tertiary referral centers, including untreated patients. All patients were operated by an endoscopic approach. Tumors were classified according to the UICC 2002. Demographic, therapeutic, histological, morbidity data, and the course of the disease were recorded. Survival rates were obtained using the Kaplan-Meier method. RESULTS: A total of 159 patients were included with a mean age of 69 years. There were 19T1, 62T2 (1M1), 36T3 (1N1), 26T4a, and 16T4b (1N2a-1N2c). The mean duration of hospitalization was 4.4 days. The histologic outcomes showed that the olfactory cleft, the posterior and anterior ethmoid sinus, and the sphenoid, maxillary, and frontal sinuses were invaded in 95, 64, 55, 19, 7, and 3 % of cases, respectively. Histologic margins were positive in 17 % (1T1, 4T2, 3T3, 2T4a, and 8T4b). In total, 130 patients received adjuvant radiotherapy on the primary tumor site (58 Gy), 24 cases were not irradiated, and 5 refused treatment. The mean follow-up was 32.5 ± 24 months. The complication rate was 19 %: 6 epistaxis, 3 meningitis, 6 CSF leaks, 2 dacryocystitis, and 8 septoplasties. The recurrence rate was 17.6 % (28 cases) within 23 ± 21 months. Eleven patients underwent a second surgical procedure. Nine patients died of their disease (3T2, 2T3, 4T4b). The global and disease-specific, recurrence-free survival rate at 3 years was 74 and 84 % respectively. CONCLUSIONS: The endoscopic approach seems to be efficient to remove sinonasal adenocarcinoma with low morbidity.

BACKGROUND: Among all studies describing COVID-19 clinical features during the first wave of the pandemic, only a few retrospective studies have assessed the correlation between olfac-tory dysfunction (OD) and the evolution of disease severity. The main aim was to assess whether OD is a predictive factor of COVID-19 severity based on the patient's medical management (outpa-tient care, standard hospital admission, and ICU admission). METHODS: A national, prospective, mul-ticenter cohort study was conducted in 20 public hospitals and a public center for COVID-19 screen-ing. During the first wave of the pandemic, from 6 April to 11 May 2020, all patients tested positive for COVID-19 confirmed by RT-PCR underwent two follow-up ENT consultations within 10 days of symptom onset. The main outcome measures were the evolution of medical management (out-patient care, standard hospital admission, and ICU admission) at diagnosis and along the clinical course of COVID-19 disease. RESULTS: Among 481 patients included, the prevalence of OD was 60.7%, and it affected mostly female patients (74.3%) under 65 years old (92.5%), with fewer comor-bidities than patients with normal olfactory function. Here, 99.3% (290/292) of patients with OD presented with non-severe COVID-19 disease. Patients reporting OD were significantly less hospi-talized than the ones managed as outpatients, in either a standard medical unit or an ICU. Conclu-sions: As regards the clinical course of COVID-19 disease, OD could predict a decreased risk of hospitalization during the first wave of the pandemic.
RESUMO
BACKGROUND: The SQ House Dust Mite (HDM) SubLingual ImmunoTherapy (SLIT)-Tablet (Acarizax) is the only allergen immunotherapy authorized by European regulatory authorities to treat HDM-induced allergic asthma (AA) that is not well-controlled by inhaled corticosteroids and associated with mild-to-severe HDM allergic rhinitis (AR). The aim of this study was to add evidence on the safety of the SQ HDM SLIT-Tablet in patients with AR, alone or with AA, under real-life conditions. METHODS: This was a French "real-life", multicenter, non-comparative, longitudinal, prospective study. It included patients initiating the SQ HDM SLIT-Tablet for either persistent moderate-to-severe HDM AR or AA not well-controlled by inhaled corticosteroids and associated with mild-to-severe HDM AR. Adverse Events (AEs) were collected at the first intake and throughout the study. Logistic regression was used to compare safety according to asthma control before treatment initiation. RESULTS: Between May 09, 2018 and May 29, 2019, 1526 patients were enrolled at 185 sites and 1483 were included in the safety population (SAF). Of them, 33.6% had suspected clinical manifestations of AA. Asthma was uncontrolled for 18.2% of the patients, partially controlled for 27.9% and well-controlled for 53.8%. Overall, 31.9% of the SAF patients experienced at least one AE. The percentage of patients with AEs was 29.9% among patients with AR alone and 35.9% among those with AA (p = 0.0193). No significant difference was observed in the rate of AE or SAE depending on asthma control at inclusion (2.2% of SAEs reported for patients with uncontrolled asthma, 1.4% for partly controlled and 1.1% for well-controlled). CONCLUSIONS: The overall results indicate a good SQ HDM SLIT-Tablet safety profile consistent with that reported in previous studies, regardless of asthma control.
RESUMO
Pharmacovigilance reports of cerebral and cardiovascular events in those who use decongestants have triggered alerts related to their use. We aimed to assess the risk of stroke and myocardial infarction (MI) associated with the use of decongestants. We conducted a nested case-crossover study of patients with incident stroke and MI identified in France between 2013 and 2016 in two systematic disease registries. Decongestant use in the three weeks preceding the event was assessed using a structured telephone interview. Conditional logistic multivariable models were used to estimate the odds of incident MI and stroke, also accounting for transient risk factors and comparing week 1 (index at-risk time window, immediately preceding the event) to week 3 (reference). Time-invariant risk factors were controlled by design. In total, 1394 patients with MI and 1403 patients with stroke, mainly 70 years old or younger, were interviewed, including 3.2% who used decongestants during the three weeks prior to the event (1.0% definite exposure in the index at-risk time window, 1.1% in the referent time window; adjusted odds ratio (aOR), 0.78; 95%CI, 0.43-1.42). Secondary analysis yielded similar results for individual events (MI/stroke). We observed no increased risk of MI or stroke for patients 70 years of age and younger without previous MI or stroke who used decongestants.

The objective of the study was to analyze the incidence, treatment, and prevention of early and late respiratory complications in a series of patients who had supracricoid partial laryngectomies with either cricohyoidoepiglottopexy or cricohyoidopexy. From medical charts, we retrospectively reviewed 101 patients who underwent supracricoid partial laryngectomies, from 1980 to 2006, for laryngeal squamous cell carcinoma, and recorded the various postoperative complications and the time of decannulation. The mortality rate was 3.96%. Early complications included broncho-pulmonary infections and laryngeal stenoses which occurred in 9.9%. Univariate analysis showed a statistically significant relationship between the pulmonary complications and neck dissections (p < 0.04). Later, they were due to laryngeal obstruction (neolaryngeal mucosal flap, residual false vocal cord fold or arytenoid edema). The median decannulation time was 8 days, and there was a significant relationship between the decannulation delay and the pulmonary complications. Only two patients had a later definitive tracheotomy. Respiratory complications after supracricoid partial laryngectomy are frequent, but can be easily managed in most cases. A preoperative pulmonary assessment is necessary to select patients. During surgery, a precise impaction of the hyoid bone with the cricoid cartilage and a repositioning of an arytenoid can avoid some postoperative stenoses.

Renal cell carcinoma (RCC) metastatic in the sinonasal cavity is rare. In many cases, it represents the initial presentation of RCC. We conducted a retrospective chart review to report the clinical presentation, imaging, and treatment of RCC metastases in the sinonasal cavity at two tertiary care referral centers. Our population was made up of 8 patients-6 men and 2 women, aged 55 to 86 years (mean: 66.9; median: 63.5)-who had been diagnosed with cancer in the sinonasal cavity. The most common complaints were epistaxis, nasal obstruction, and diplopia. Cancers were located in the ethmoid sinus (n = 3), nasal cavity (n = 2), sphenoid sinus (n = 2), and maxillary sinus (n = 1). Local treatment involved resection and adjuvant radiotherapy in 4 patients, surgery alone in 2 patients, and radiotherapy alone in the other 2. The lesion was embolized before surgery in 4 cases. We also performed a critical review of similar published cases. Our literature review covered 53 cases of RCC metastatic to the sinonasal cavity, including ours. Metastases were the first presentation of RCC in 24 of these cases (45.3%); in our series, the metastases led to the diagnosis of the primary RCC in 3 cases (37.5%). In the 53 reported cases, metastatic resection was performed on 35 patients (66.0%). Survival data were available for 22 of these operated patients, and 17 of them achieved a complete local response. Adjunctive radiotherapy was not associated with a better local response. Overall survival was significantly better in patients who had an isolated metastasis rather than multiple metastases (p = 0.013). There was no difference in overall survival between patients whose metastasis represented the initial presentation of RCC and those whose metastasis did not (p = 0.95). We recommend that sinonasal metastasis be suspected in the event of unilateral nasal bleeding or nasal obstruction in patients diagnosed with RCC. Embolization may prevent abundant bleeding during removal. Surgery may improve the quality of life of these patients while decreasing nasal obstruction and bleeding.

BACKGROUND: Oncology involves complex care and multidisciplinary management of patients; however, misinformation and ineffective communication remain problematic. OBJECTIVE: The educational objective of our study was to develop a new teaching method to improve cancer treatment and management by emphasizing the link between hospitals (inpatients) and their surrounding communities (outpatients). METHODS: A team of 22 professionals from public and private institutions developed a small private online course (SPOC). Each offering of the course lasted 6 weeks and covered 6 topics: individual health care plans, cancer surgery, ionizing radiation, cancer medicines, clinical research, and oncological supportive care. For participants in the course, we targeted people working in the cancer field. The SPOC used an active teaching method with collaborative and multidisciplinary learning. A final examination was offered in each session. We evaluated participants' satisfaction rate through a questionnaire and the success of the SPOC by participants' completion, success, and commitment rates. RESULTS: Of the total participants (N=1574), 446 completed the evaluation form. Most participants were aged 31 to 45 years. Participants included 56 nurses, 131 pharmacists, 80 from the medical field (including 26 physicians), 53 from patients' associations, 28 health teachers, and 13 students (medical and paramedical). Among the participants, 24.7% (90/446) had an independent medical practice, 38.5% (140/446) worked in a public institution, and 36.8% (134/446) worked in a private institution. After completing the SPOC sessions, 85.9% (384/446) thought they had learned new information, 90.8% (405/446) felt their expectations were met, and 90.4% (403/446) considered that the information had a positive impact on their professional practice. The completion rate was 35.51% (559/1574), the success rate was 71.47% (1025/1574), and the commitment rate was 64.67% (1018/1574). Concerning the cost effectiveness of SPOC compared with a traditional classroom of 25 students, online education became more effective when there were more than 950 participants. CONCLUSIONS: SPOCs improved the management of oncology patients. This new digital learning technique is an attractive concept to integrate into teaching practice. It offered optimal propagation of information and met the students' expectations.
RESUMO
BACKGROUND: Given the particularities of olfactory neuroblastoma (ONB) and the lack of studies on the subject, a multicenter collaborative study was conducted to assess treatment strategy. METHODS: Fifty-three patients with ONB were included from the French Rare Head and Neck Cancer Expert Network (REFCOR) database: 16T1, 8T2, 19T3, and 10T4. All cases were treated endoscopically with skull base removal and repair in 26 cases (49%) and without external craniotomy. RESULTS: The overall survival (OS) and disease-free survival (DFS) rates at 5 years were 87% and 71%, respectively, with mean follow-up of 45.4 ± 26.5 months. The complication rate was 18.8% with 4 cases of meningitis. Pathological analysis showed positive margins in 26.8%, notably on the dura-mater and periorbita, without impairment of OS or DFS. Forty-eight patients received adjuvant radiotherapy on T ± N. Ten patients had a recurrence (18.9%). Six patients died of their disease. Prophylactic neck irradiation seemed to reduce the recurrence rate. CONCLUSION: Exclusively endoscopic treatment proved efficient and reliable in a large controlled series.

OBJECTIVE: The purpose of this study is to describe the treatment of epistaxis in hospital emergency departments and to identify the principal risk factors for more severe episodes of bleeding. STUDY PROTOCOL: Prospective cross-sectional epidemiological study MATERIAL AND METHODS: This study was carried out in 23 hospital centres in France, most of them teaching hospitals. Every patient presenting non-traumatic epistaxis or else associated with hereditary hemangioma during two consecutive and separate 24-hour periods were included. RESULTS: Fifty patients were included in the study. Nasal bleeding was stopped within 30 minutes for 47 patients. Fourteen patients were hospitalized. The risk factors for severe epistaxis included either copious bleeding or else bleeding for more than 6 hours or patients aged 65 and over. A history of repeated nasal packing and/or taking medication with a known hemorrhagic risk was associated with the amount and duration of bleeding (p < 0.05). CONCLUSION: Risk factors for severe epistaxis should be identified as to improve patient care and avoid treatment failure or useless hospitalization.

OBJECT: To report the morbidity and long term results in the treatment of paragangliomas by transarterial embolization with ethylene vinyl alcohol (Onyx), either as preoperative or palliative treatment. METHODS: Between September 2005 and 2012, 18 jugulotympanic, 7 vagal, and 4 carotid body paragangliomas (CBPs) underwent Onyx embolization, accordingly to our head and neck multidisciplinary team's decision. CBPs were embolized preoperatively. Jugulotympanic and vagal paragangliomas underwent surgery when feasible, otherwise palliative embolization was carried out alone, or in combination with radiotherapy or tympanic surgery in the case of skull base or tympanic extension. Treatment results, and clinical and MRI follow-up data were recorded. RESULTS: In all cases, devascularization of at least 60% of the initial tumor blush was obtained; 6 patients underwent two embolizations. Post-embolization, 8 patients presented with cranial nerve palsy, with partial or complete regression at follow-up (mean 31 months, range 3-86 months), except for 2 vagal and 1 hypoglossal palsy. 10 patients were embolized preoperatively; 70% were cured after surgery and 30% showed residual tumor. 19 patients received palliative embolization, of whom 5 underwent radiotherapy and 3 received tympanic surgery post-embolization. Long term follow-up of palliative embolization resulted in tumor volume stability (75%) or extension in intracranial or tympanic compartments. Onyx embolization of CBPs resulted in more difficult surgical dissection in 2 of 4 cases. CONCLUSIONS: Onyx embolization is a valuable alternative to surgery in the treatment of jugulotympanic and vagal paragangliomas; tympanic surgery or radiosurgery of the skull base should be considered in selected cases. Preoperative Onyx embolization of CBPs is not recommended.

OBJECTIVES/HYPOTHESIS: Adipose derived stromal cells (ASCs) are abundant and easy to prepare. Such cells may be useful for treating severe vocal disturbance caused by acute vocal fold scars. STUDY DESIGN: Prospective animal experiments with controls. METHODS: Twenty New-Zealand white rabbits were used in the present study. We evaluated vocal fold healing, with or without injection of autologous ASCs, after acute scarring. A defined lesion was created and the ASCs were immediately injected. Vocal fold regeneration was evaluated histomorphometrically and via viscoelastic analysis using an electrodynamic shaker. RESULTS: Six weeks after ASC injection, vocal folds exhibited significantly less inflammation than control folds (P < 0.005). In addition, hypertrophy of the lamina propria and fibrosis were significantly reduced upon ASC injection (P < 0.02). The decrease in viscoelastic parameters was less important in the ASC injected group compared to the noninjected group (P = 0.08). CONCLUSION: Injection of autologous ASCs improved vocal fold healing in our preclinical model. Further studies are needed, but this method may be useful in humans. LEVEL OF EVIDENCE: NA. Laryngoscope, 126:E278-E285, 2016.

STUDY OBJECTIVES: In maxillary nosocomial sinusitis (MNS) related to severe sepsis, nitric oxide (NO) concentration in the maxillary sinuses is drastically reduced secondarily to a downregulation of type-2 NO synthase. NO plays a major role in nonspecific immune defense of sinuses. We therefore aimed to study maxillary NO concentration during the treatment of MNS with drainage, daily lavage, and removal of any nasally introduced tube. PATIENTS AND METHODS: Nine patients were studied during the first 4 days of treatment of MNS. We measured the concentration of NO gas in the maxillary sinus and in the nasal cavity, and the NO metabolite levels (nitrites/nitrates [NOx]) in the sinus lavages. MEASUREMENTS AND RESULTS: Maxillary NO concentration (median [25 to 75 percentile]) increased from 70 parts per billion (ppb) [40 to 100 ppb] to 2,050 ppb (1,700 to 3,000 ppb) after 4 days of treatment of MNS (p < 0.0001). In the meantime, nasal NO increased from a median of 100 ppb (98 to 148 ppb) to 180 ppb (180 to 188 ppb) [p < 0.001]. At any time, there was a correlation between maxillary NO (logarithmic value) and nasal NO (r2 = 0.57, p < 0.0001). NOx levels remained stable in the lavages. CONCLUSIONS: We conclude that the treatment of the sinusitis with drainage, daily lavage, and removal of the gastric tube lead to a spectacular increase of maxillary and nasal NO concentrations.

The prevalence of nasal polyposis (NP) in France (2.11 per cent) and its epidemiology (detection, medical management, patients' characteristics, risk factors, associated diseases, etc.) were determined in a population-based, cross-sectional, case-control study of 10 033 adults carried out in 2002. The impact of this disease on daily living was also studied, by the analysis of potential sleep disorders (validated questionnaire) and quality of life (QOL, SF-36 questionnaire) of NP patients, in a comparison with a matched-control group of individuals without NP. A quarter of NP patients (24.6 per cent) reported a feeling of general discomfort due to their nasal condition, during the day as well as the night in most of these cases (61.2 per cent). Compared with controls, NP patients have a two-fold higher risk of suffering sleep disturbance (odds ratio [OR]: 2.25, 95 per cent confidence interval [95% CI] [1.54; 3.29]). Snoring was reported by 50.5 per cent of NP patients vs 35.7 per cent of controls (p < 0.001). All scores from the SF-36 questionnaire demonstrated a significant negative impact of NP on the different aspects of QOL. The current study underlines the negative impact of NP on QOL and sleep, two dimensions that are rarely considered in its pathology. In addition to the discomfort and lowered QOL experienced by patients with this disease, a significant increase in sleep disorders was shown, suggesting a risk of suffering further chronic diseases and complications.
