Efficacy of dupilumab in real-life settings: a STROBE study

BACKGROUND

Dupilumab, a monoclonal antibody targeting IL-4 and IL-13, has demonstrated its efficacy in several clinical trials. However, to date, real-life data remains limited.

OBJECTIVE

The aim of our study was to assess the real-life impact of dupilumab on patients with severe and uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP) quality of life.

MATERIALS AND METHODS

This was a retrospective, monocentric, observational, real-life study, conducted in accordance with the STROBE guidelines. The following parameters were collected before treatment and at 1, 4, and 12 months: Sino-Nasal Outcome Test-22 (SNOT-22), nasal polyp score (NPS), Sniffin' Sticks-16 (SST-16), visual analog scale (VAS) for loss of smell, nasal congestion score (NCS), gustatory VAS, asthma control, oral corticosteroid usage, surgery rates, and occurrence of side effects.

RESULTS

The study included 47 patients. SNOT-22 scores decreased from 52.4 ± 24.3 to 12.7 ± 10.5 at 12 months (p < 0.001). NPS decreased from 6.15 ± 1.71 to 1.57 ± 1.40 at 12 months (p < 0.001). SST-16 scores increased from 1.6 ± 2.83 to 9.1 ± 5.4 at 12 months (p < 0.001). NCS decreased from 2.45 ± 0.72 to 0.38 ± 0.63 at 12 months (p < 0.001). Prior to treatment, 72.3% were using oral corticosteroids, compared to 17.0% at 12 months (p < 0.01). Two patients required additional surgery, and 17% reported completely uncontrolled asthma, compared to 0% at 12 months (p < 0.01).

CONCLUSION

Our real-life results confirm the efficacy of Dupilumab in the treatment of severe and uncontrolled CRSwNP.

Assessing normal values for the FACE-Q rhinoplasty module: An observational study

OBJECTIVES

The goal of this study was to determine normal values for the FACE-Q rhinoplasty module.

DESIGN

A prospective monocentric observational cohort study.

SETTING

We tested FACE-Q Satisfaction with Nose and Satisfaction with Nostrils in two groups of patients, seeking or not a rhinoplasty.

PARTICIPANTS

One hundred and four patients were included in the study, fifty-two in each group.

MAIN OUTCOME MEASUREMENTS

Primary outcome was to identify possible cutting scores to establish normal values for each of the FQRM questionnaires.

RESULTS

Regarding the Satisfaction with Nose scale, there was a statistically significant difference between the two groups (P < .001). Area under the ROC curve was 0.964 (95% CI = 0.931-0.997). Forty-seven points was the value presenting the best Youden index (sensitivity = 96.2%, specificity = 86.5%). Regarding the Satisfaction with Nostrils scale, there was a statistically significant difference between the two groups (P < .001). Area under the ROC curve was 0.820 (95% CI = 0.741-0.899). Sixty-four points was the value presenting the best Youden index (sensitivity = 94.2%, specificity = 53.8%).

CONCLUSION

This is the first study to generate normative data for the FACE-Q rhinoplasty module. The findings presented here have important implications for future clinical care and research. The definition of a normal score can help practitioners to better analyse their patients and to support a therapeutic indication.

Outcomes of septorhinoplasty: a new approach comparing functional and aesthetic results

The aim of this study was to compare objective and subjective functional results of septorhinoplasty with subjective aesthetic results. A prospective study was performed including global and subgroup analyses (primary versus secondary septorhinoplasty). Three instruments were used to evaluate pre- and postoperative results: rhinomanometry for the objective functional analysis, the Nasal Symptom Obstruction Evaluation (NOSE) scale for the subjective functional analysis, and the Rhinoplasty Outcome Evaluation (ROE) scale for the subjective aesthetic analysis. A septorhinoplasty was performed in all cases. Thirty-five patients were included (22 female), of whom 74% underwent primary septorhinoplasty. The correlation between rhinomanometry, NOSE and ROE scores was analysed. Mean resistance of the two nasal cavities was 4.9 (standard deviation (SD) 8.35) sPa/ml before surgery and 0.8 (SD 0.7) sPa/ml after surgery. NOSE and ROE scores were, respectively, 72.5/100 (SD 21.7) and 7.5/24 (SD 11.3) before surgery and 22/100 (SD 20.6) and 18/24 (SD 17.3) after surgery. Patients complaining of postoperative nasal obstruction had a worse aesthetic evaluation. Correction of the functional disease appears to be as important as aesthetic correction. This study comparing functional and aesthetic results after septorhinoplasty could provide a basis for future studies.

Endoscopic surgery for sinonasal tumors: The transcribriform approach

Over the past 10 to 20 years, endoscopic endonasal surgery has become for many teams the preferred treatment for sinonasal tumors. Technical advances in the field of surgical instrumentation (good visualization, hemostasis…) and the progress of imaging guidance (to avoid neurovascular complication) has made those procedures simpler and safer. Nevertheless, endonasal endoscopic procedures require a trained surgical team of ENT specialist and neurosurgeon. Endoscopic endonasal surgery has been reported to be feasible for all types of sinonasal tumors whether benign tumors such as inverted papillomas, or malignant tumors. In this paper, we mostly focus on the principles underlying the transcribriform approach, which is dedicated to the surgery of CSF leaks, encephaloceles/meningoceles, access to benign intracranial tumors such as olfactory groove meningiomas, and the resection of sinonasal malignancies with skull base invasion such as olfactory neuroblastomas.

The MiRa scale, a new standardised scale for evaluating nasal deformities before and after septorhinoplasty: A prospective study comparing patient satisfaction and the surgeon's assessment

OBJECTIVES

The objective was to assess the reliability of a new standardised scale for evaluating nasal anomalies in order to compare the surgeon's assessment and patient satisfaction.

DESIGN

Monocentric prospective cohort study.

SETTINGS

First, we validated the reliability of the MiRa scale; then, we compared the surgeon's assessment and patient satisfaction.

PARTICIPANTS

Fifty-two patients underwent septorhinoplasty surgery and gave their written consent before inclusion.

MAIN OUTCOME MEASUREMENTS

Primary outcome measurement was to validate the reliability of the MiRa scale: two observers analysed all records twice. Intra-observer reproducibility and interobserver reproducibility were evaluated using the intraclass correlation coefficient (ICC). Secondary outcome measurement was to compare the surgeon's assessment and patient satisfaction: MiRa and ROE (Rhinoplasty Outcome Evaluation) scores were established for each patient prior to and 6 months after surgery.

RESULTS

Using the MiRa scale, ICC for intra- and interobserver reproducibility was, respectively, 95.4% and 96%, showing no statistical difference (P=.70, P=.45). Good correlation scores were, respectively, 93% and 92%. Mean ROE scores were 7.1/24 (SD=11.3) before and 19.3/24 (SD=17.3) after surgery (P<.05). We found an increase in MiRa and ROE scores of +19.75% and +51.25% (P<.05), respectively. The average postoperative ROE score in the primary septorhinoplasty group was 20.4 (SD=14.4) and 17.2 (SD=23.1) in the secondary septorhinoplasty group (P<.05).

CONCLUSION

MiRa scale is a reliable, standardised tool to evaluate surgical outcome in septorhinoplasty surgery. It provides an objective and reproducible score. The surgeon's assessment was more critical than patient satisfaction. Patient satisfaction is more difficult to achieve in cases involving a secondary septorhinoplasty.

Sentinel lymph node biopsy in head and neck melanoma: A single institution analysis

INTRODUCTION

The aim of our study was to analyze a series of patients from our institution who underwent surgery for head and neck cutaneous melanoma and who received sentinel lymph node biopsy (SLNB).

MATERIAL AND METHODS

A single-center observational cohort of 120 head and neck melanoma patients was investigated from 2002 to 2011.

RESULTS

Among the 107 patients (89.2%) with lymph node identified during lymphoscintigraphy, at least one node was collected and analyzed in 96 patients (90.6%). A positive sentinel lymph node was found in 9.4% of patients. Our data showed higher failure rate of lymphoscintigraphic identification (11.7%), lower rate of SLN positivity (9.4%), and higher false-negative rate of SLNB (24.1%) than the usualfigures established for malignant melanomas in other locations. After a mean follow-up of 38.1 months, the disease-free survival (DFS) rate in the positive SLN group was 53% vs 75% for the negative SLN after 2 years of follow-up and 53% vs 48% after 5 years (p = 0.44).

CONCLUSION

The complexity of lymphatic drainage and the anatomy of the cervical region probably accounts for a specificities which result in a lower predictive value of SLNB in head and neck melanoma than in MM in other locations.

[Prognostic value of sentinel lymph node in Merkel cell carcinoma of the head and neck]

INTRODUCTION

Merkel cell carcinoma (MCC) is a rare neuroendocrine skin tumor. The aim of our study was to analyze the prognosis of patients operated on for CCM and having no lymph node involvement after analysis of sentinel lymph node (SLN).

MATERIAL AND METHOD

This was a retrospective study of 10 cases of CCM stage I or II who received the SLN technique in our institution between 2003 and 2010. RESULTS Among the 10 patients, 7 had an identification of at least one SLN, among which the node could be surgically removed in 6 cases. In cases of failure of SLN technique, a neck dissection +/- parotidectomy was performed. No lymph node metastasis was found in our series. Mean follow-up was 38 months. The overall survival rate was 100% at 2 years and 50% at 5 years. The Disease-free survival was 85% at 2 and 5 years.

CONCLUSION

Our results show that the technique of sentinel lymph node is a reliable tool for evaluating nodal status of patients with CCM and that pN0 patients have a good prognosis.

Fine-needle aspiration cytology in the management of parotid masses: evaluation of 249 patients

INTRODUCTION

The role of fine-needle aspiration cytology (FNAC) in the management of parotid tumours is still the subject of controversy. The purpose of this study was to determine the diagnostic value of FNAC in our institution in order to define its place in the diagnostic strategy.

PATIENTS AND METHODS

This retrospective study was based on 249 patients who had undergone preoperative FNAC before being operated in our institution between 2001 and 2008. All examinations were performed and interpreted by the same experienced pathologist.

RESULTS

Among the 249 patients included in this study, 187 (75%) had a benign tumour and 62 (25%) had a malignant tumour. No complications of FNAC were observed. Cytological findings were non-contributory in 47 patients (18%). The sensitivity of FNAC for the diagnosis of malignancy was 80% with a specificity of 89.5%. Among the 11 false-negative results, lymphomas and low-grade mucoepidermoid carcinomas were the most common histological types. Among the 16 false-positive results, Warthin's tumours, pleomorphic adenomas and lymphoepithelial lesions were the most common histological types. Accurate histological classification of the tumour was reported in 79.5% of cases (86% for benign tumours and 44% for malignant tumours).

CONCLUSION

FNAC is a reliable examination providing important information to the surgeon in the preoperative diagnostic assessment.
