The Prognostic Value of Olfactory Dysfunction in Patients with COVID-19: The COVIDORA Study.

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.

Osteocutaneous-flap-related osteomyelitis following mandibular reconstruction: a cohort study of an emerging and complex bone infection.

Osteocutaneous flap (OCF) mandible reconstruction is at high risk for surgical site infection. This study aimed to describe diagnosis, management, and outcome of OCF-related osteomyelitis. All patients managed at our institution for an OCF-related osteomyelitis following mandible reconstruction were included in a retrospective cohort study (2012-2019). Microbiology was described according to gold-standard surgical samples, considering all virulent pathogens, and potential contaminants if present on at least two samples. Determinants of treatment failure were assessed by logistic regression and Kaplan-Meier curve analysis. The 48 included patients (median age 60.5 (IQR, 52.4-66.6) years) benefited from OCF mandible reconstruction mostly for carcinoma ( n = 27 / 48 ; 56.3 %) or osteoradionecrosis ( n = 12 / 48 ; 25.0 %). OCF-related osteomyelitis was mostly early ( ≤ 3 months post-surgery; n = 43 / 48 ; 89.6 %), presenting with local inflammation ( n = 28 / 47 ; 59.6 %), nonunion (wound dehiscence) or sinus tract ( n = 28 / 47 ; 59.6 %), and/or bone or device exposure ( n = 21 / 47 ; 44.7 %). Main implicated pathogens were Enterobacteriaceae ( n = 25 / 41 ; 61.0 %), streptococci ( n = 22 / 41 ; 53.7 %), Staphylococcus aureus ( n = 10 / 41 ; 24.4 %), enterococci ( n = 9 / 41 ; 22.0 %), non-fermenting Gram-negative bacilli ( n = 8 / 41 ; 19.5 %), and anaerobes ( n = 8 / 41 ; 19.5 %). Thirty-nine patients (81.3 %) benefited from surgery, consisting of debridement with implant retention (DAIR) in 25 / 39 (64.1 %) cases, associated with 93 (IQR, 64-128) days of antimicrobial therapy. After a follow-up of 18 (IQR, 11-31) months, 24 / 48 (50.0 %) treatment failures were observed. Determinants of treatment outcomes were DAIR (OR, 3.333; 95 % CI, 1.020-10.898) and an early infectious disease specialist referral (OR, 0.236 if ≤ 2  weeks; 95 % CI, 0.062-0.933). OCF-related osteomyelitis following mandibular reconstruction represents difficult-to-treat infections. Our results advocate for a multidisciplinary management, including an early infectious-disease-specialist referral to manage the antimicrobial therapy driven by complex microbiological documentation.

Failure of anterior skull base reconstruction for sinonasal carcinoma: consequence on the postoperative follow up. A multicentre evaluation of management.

BACKGROUND: Numerous techniques for closure of the anterior skull base in cancer patients have a high success rate but management of failure is poorly documented. OBJECTIVES: To standardize the post-operative follow-up after reconstruction surgery of the anterior skull base after removal for sinonasal carcinoma. MATERIALS AND METHODS: Retrospective review of failure of anterior skull base reconstruction between 2005 and 2018 in a multicenter setting. RESULTS: Twenty four patients were included. Reconstruction failure was detected by a cerebrospinal (CSF) leak in 79.2%, by an infectious complication without CSF leak (i.e. meningitis) in 12.5%, and in 8.3% by extensive pneumocephalus. Failure was observed during the first week after surgery in 75% of patients, in the second week in 21%, and in 4% after day 15. The delay in discovery of the failure was associated with multilayer reconstruction (p=.03). Failure was treated surgically in 54% of the patients and medically in 46%, with a similar success rate (85 vs. 100%). CONCLUSION AND SIGNIFICANCE: After carcinologic resection of the anterior skull base, monitoring should be systematic during the first postoperative week. Surgical management of failure is not always necessary.

A Novel ALK-THBS1 Fusion in a Laryngeal Inflammatory Myofibroblastic Tumour: A Case Report and Literature Review.

Inflammatory myofibroblastic tumor (IMT) is an uncommon neoplasm most frequently seen in the abdomino-pelvic region and lungs of children and young adults. Laryngeal tumors are rare. We present a case of a 23-year-old patient with a 5 month history of laryngitis and aphonia unresolved by corticotherapy. Laryngoscopy revealed a small, non-ulcerated, subepithelial, polypoid mass arising from the right vocal cord. The diagnosis of IMT with ALK expression was supported by histopathologic and molecular analysis. The THBS1 fusion partner was identified by RNA-sequencing analysis for the first time in a laryngeal IMT. This fusion partner has only been identified in six uterine IMTs thus far. Conservative excision of the lesion yielded excellent functional results for the patient. The voice was preserved and no recurrences were seen after 6 months of follow-up.

Neoadjuvant modified TPF (docetaxel, cisplatin, fluorouracil) for patients unfit to standard TPF in locally advanced head and neck squamous cell carcinoma: a study of 48 patients.

TPF (docetaxel, cisplatin, fluorouracil) is the standard chemotherapy used for induction in locally advanced head and neck squamous cell carcinoma (LAHNSCC). Its toxicity limits it to younger patients with good functional status and without significant comorbidity. Since modified TPF (mTPF) demonstrated higher tolerability with similar efficacy in gastric cancer, we tested this scheme on frail patients.From July 2010 to July 2014, the files of the 48 patients treated for LAHNSCC with mTPF in three French institutions were retrospectively collected.mTPF was chosen because of age>70 years, or severe denutrition, or PS>1, or severe comorbidities or after severe toxicity of standard TPF. During the first 4 cycles, 2 patients died, 14 secondary hospitalizations were required and 10 patients stopped treatment due to no lethal toxicity. Two patients died during radiotherapy.The response rate was 83% (19% complete response). With a median follow-up of 15.2 months, 4 patients died during treatment, 8 died of non-head and neck cancer related disorders, 18 progressed (17 deaths) and 18 were free of disease. The median overall survival was 18.5 months (95% IC: 16.9-30.0).mTPF is effective in terms of response rate compared with the standard TPF and could become a new option in induction for frail patients with LAHNSCC.

Experience of multidisciplinary team meetings in vestibular schwannoma: a preliminary report.

To assess the contribution of multidisciplinary team meetings (MTM) on vestibular schwannoma management as well as to (1) compare professional compliance to national guidelines and (2) study the percentage of loss to follow-up in cases of conservative management by radiologic observation. A retrospective descriptive study of MTMs held between January 2011 and May 2013 in a tertiary referral center. Patients were classified in three groups according to the MTM decision (observation, surgery or radiotherapy). A total of 363 cases were discussed during the study period (29 months). One hundred and ninety-four decisions (53.4%) were for conservative management with radiologic observation, 130 (35.8%) for surgery, and 39 (10.7%) for radiation therapy. The sex ratio was 0.94, and the patients had a median age of 59 years (range 18-86 years). Most of the vestibular schwannomas (74.2%) were small (stages I and II). Global concordance between the MTM decision and International Radiosurgery Association guidelines was 88.7%. Twenty-three percent of the 104 files that were discussed in MTMs between January 2011 and July 2012, for which conservative management was decided, were lost to follow-up by 18 months. Management of vestibular schwannoma remains controversial, but it usually depends on the evolutive status. MTMs improve practice and facilitate the creation and maintenance of local registries. Future studies in MTMs are warranted to evaluate the benefit and evaluated if MTM could optimize long-term follow-up, limiting loss to follow-up in the observation of vestibular schwannomas that may be evolutive.

Alimentation impact of treatments of 254 oropharyngeal cancers (1998-2003).

Objective. To analyze the functional impact of the various possible treatments of oropharyngeal squamous cell carcinomas to find the main prognostic factors of dysphagia induced by these treatments. Patients. Clinical data from 254 patients treated for squamous cell carcinoma of the oropharynx between 1998 and 2003 were retrospectively analyzed. A multivariate model enabled us to evaluate the role of each potentially harmful factor on swallowing. Main Outcome Measures. The significant factors influencing the consumption of liquid, pasty, and normal food were the same: the initial T stage and the type of treatment. Conclusion. Whatever the possible and selected treatment was, the impact on the functional capacities, and thus, the quality of life of the patients was considerable. Even though we could not significantly demonstrate exclusive radiotherapy caused more long-term undesirable effects than surgery followed by radiotherapy, our daily practice has shown that we should favour the latter.
