Ciliary Functional Analysis in Chronic Rhinosinusitis with Polyps after Multimodal Intervention: Oral Corticosteroid, Functional Endoscopic Sinus Surgery, and Omalizumab Injection.

In her late 50 s, a woman with a medical history of endoscopic sinus surgery for chronic rhinosinusitis with nasal polyps (CRSwNP) experienced a relapse of nasal polyps, significantly impacting her breathing and sense of smell. She underwent a multifaceted treatment approach, including oral corticosteroids, functional endoscopic sinus surgery, and omalizumab injections. Digital high-speed videomicroscopy (DHSV) revealed only partial improvement in ciliary beat pattern and ciliary beat frequency with oral corticosteroid treatment, while significant improvement in these ciliary parameters was observed with omalizumab injections. Furthermore, administration of omalizumab resulted in a decrease in her SNOT-22 (Sinonasal Outcome Test 22) score. Notably, this case report represents the first study investigating ciliary function using DHSV in a patient treated with omalizumab.

A prospective multicentre REFCOR study of 470 cases of head and neck Adenoid cystic carcinoma: epidemiology and prognostic factors.

BACKGROUND: Adenoid cystic carcinoma (ACC) accounts for 1% of malignant head and neck tumours [1] and 10% of salivary glands malignant tumours. The main objective of our study is to investigate the prognostic factors influencing the event-free survival (EFS) of patients with ACC. PATIENTS AND METHODS: A multicentre prospective study was conducted from 2009 to 2018. All 470 patients with ACC whose survival data appear in the REFCOR database were included in the study. The main judgement criterion was EFS. Both a bivariate survival analysis using log-rank test and a multivariate using Cox model were performed using the R software. RESULTS: Average age was 55 years. Females accounted for 59.4% of the cohort. The body mass index (BMI) was normal in 86% of cases. Tumours were located in minor salivary glands in 60% of cases. T3/T4 stages represented 58%; 89% of patients were cN0. histological grade III was observed on 21% of patients. The EFS and overall 5-year survival rates were 50% and 85%, respectively. After adjustment, the most significant pejorative prognostic factors were age ≥65 years (hazard ratio [HR] = 1.67), BMI<16.5 (HR = 2.62), and lymph node invasion cN (HR = 2.08). CONCLUSION: Age, BMI and N stage are the three main clinical prognostic factors determining EFS identified in this prospective series of patients with ACC. Such findings open new research perspectives on the influence of these components on initial patient care.

Skull base reconstruction with pedicled nasoseptal flap: Technique, indications, and limitations.

Endoscopic skull base surgery allows extensive tumor resection but results in large defects requiring robust dural repair. The vascularized nasal septal flap pedicled on the posterior nasal septal artery is known to have an excellent success rate for dural defect coverage. Detailed step-by-step descriptions of the harvest and placement of this flap are scarce. Using a sketch, images, and a video, we describe a detailed method for endoscopically harvesting and placing a nasoseptal flap (NSF). We also describe the indications and the decision process leading to the use of NSF.

Weekly cisplatin with radiotherapy for locally advanced head and neck squamous cell carcinoma.

PURPOSE: Although commonly used for the treatment of locally advanced head and neck squamous cell carcinoma (HNSCC) concomitant radio-chemotherapy (RT-CT) with weekly cisplatin has not been definitely studied. We conducted a single centre retrospective study with the aim to evaluate efficacy and acute toxicity of definitive concomitant RT-CT with 40 mg/m2 weekly cisplatin in patients with locally advanced HNSCC with a particular emphasis on RT modality (conventional or accelerated) and dose of cisplatin delivered. METHODS: One hundred and twelve consecutive patients were included. They were given cisplatin 40 mg/m2)week concomitantly with conventionally fractionated (CFRT) (N=33) or accelerated (ART) (N=79) RT. RESULTS: RT was delivered according to the treatment plan in 104 patients and full dose was given to 107 patients. A median cumulative cisplatin dose of 240 mg/m2 was administered to patients treated with CFRT and of 200 mg/m2 to those treated with ART. Overall complete response rate was 81.3%. With a median follow up of 38.4 months, median overall survival (OS) was 75 months, not influenced by RT type or cisplatin dose received. The most clinically significant grade 3 or 4 acute toxicities were stomatitis (35.7%), neutropenia (25%), anemia (12.5%) and acute kidney injury (5.4%). CONCLUSIONS: Our study shows that a median cumulative dose of 200 mg/m2 cisplatin can be safely administered using a weekly regimen to patients treated with concomitant RT (CFRT or ART). Efficacy results and toxicity compare favorably with those described with triweekly cisplatin RT-CT, suggesting that a randomized comparison should be undertaken.
