RESUMEN
OBJECTIVE: The aim of this article is to describe step by step the endoscopic treatment of acquired subglottic stenosis (SGS) in an infant and to show the endoscopic results one month after surgery. STUDY DESIGN: Case presentation with instructional video. SETTING: University Hospital of Verona, Italy. METHODS: We present the case of a 6-month-old ex-26-week preterm female infant who required prolonged intubation in the neonatal period. She referred to our hospital for persistent inspiratory and expiratory stridor, and laboured breathing. The endoscopic dynamic examination of upper airway revealed the presence of type 3 laryngomalacia and subglottic stenosis grade III according to Myers-Cotton classification. An endoscopic balloon laryngoplasty was planned. Two laryngeal dilatations were performed. The endoscopic exploration after the first dilatation showed the presence of a subglottic cyst on the anterior surface of the subglottis. The treatment of subglottic cyst consisted of marsupialization of the cyst with cold microinstruments, and subsequent suction of its content. RESULTS: An endoscopic check-up was carried out one month after surgery. The examination of the upper airway under spontaneous respiration didn't show significant subglottic stenosis. A very small subglottic cyst under the anterior commissure was observed. However, no more balloon dilatations or marsupialization of the cyst were performed in order to avoid the formation of synechiae. CONCLUSION: Treatment of SGS must be planned according to the extent of the stenosis and the history of the patient. Endoscopic procedures, such as balloon dilatation and cyst marsupialization, are best chosen for patients with isolated SGS without prior treatment failure.

Adherence to treatment is essential in chronic rhinosinusitis with nasal polyposis (CRSwNP). Intranasal corticosteroids (INCS) are the first-line therapy, followed by systemic corticosteroids and surgery if needed. In cases of refractory disease, biologics are added to conventional treatment, making adherence to INCS crucial in assessing eligibility for these targeted therapies. The purpose of this review is to examine INCS adherence assessment and rate, before starting and during biologic therapy. We conducted a comprehensive literature review focusing on INCS adherence in CRSwNP treated with biologics, including randomized controlled trials and real-life studies. The search extended to studies on allergic and non-allergic rhinitis to provide broader insights into tools to assess the INCS adherence. The result was that adherence to INCS in CRSwNP is underexplored, with only a few studies addressing it directly. Various tools for adherence assessment have been identified, but none are universally accepted as standard. The review also highlights the complexity of factors influencing adherence rates. Effective CRSwNP management requires a paradigm shift to prioritize adherence in treatment guidelines and clinical practice. The review advocates for improved adherence assessment tools, a deeper understanding of influencing factors, and the integration of personalized medicine approaches, especially for biologic therapies.
RESUMEN
Hypereosinophilic syndromes (HES) represent a group of rare dis-immune conditions characterized by blood hyper-eosinophilia and eosinophilic related burden. Especially the idiopathic subtype (I-HES) is particularly difficult to diagnose because of its heterogeneous clinical presentation, the lack of specific findings on physical exam, lab tools, and imaging informative enough to unequivocally confirm the diagnosis and the overlap with other entities, including eosinophilic organ-diseases or systemic dis-immune conditions other than I-HES (from atopy to eosinophilic granulomatosis with polyangiitis [EGPA], the last often extremely difficult to distinguish from HES). Taken together, all the features mentioned above account for an extremely difficult early recognition HES and on-time referral to a specialized centre. The referral itself is challenging due to a not univocal specialist identification, because of the variability of physicians managing HES in different settings (including allergist/clinical immunologist, haematologist, internal medicine doctors, pulmonologist, rheumatologist). Furthermore, the approach in terms of personalized treatment identification and follow-up plan (timing, organ assessment), is poorly standardized. Further translational and clinical research is needed to address the mentioned unmet needs, but on practical grounds increasing the overall clinicians' awareness on HES and implementing healthcare pathways for HES patients represent a roadmap that every clinician might try to realize in his specific setting. The present review aims at providing an overview about the current challenges and unmet needs in the practical approach to HES and rare hypereosinophilic allergo-immunological diseases, including a proposal for an innovative multidisciplinary organizational model.
RESUMEN
INTRODUCTION: Dupilumab is a human monoclonal antibody that targets both IL-4 and IL-13 signaling. It is currently indicated for the treatment of asthma, moderate-to-severe atopic dermatitis, and chronic rhinosinusitis with nasal polyps (CRSwNP). Eosinophilia has been reported as a potential adverse event in treated patients. AREAS COVERED: A selective search on PubMed and Medline up to January 2022 was performed, by focusing on dupilumab-induced hypereosinophilia described in clinical trials, real-life studies, and case reports. The possible mechanisms underlying dupilumab-induced hypereosinophilia and the eosinophil-related morbidity have also been explored. EXPERT OPINION: Dealing with dupilumab-induced hypereosinophilia represents a clinical challenge for clinicians managing patients on dupilumab therapy. An algorithm for the practical management of dupilumab-induced hypereosinophilia has been proposed, in order to properly investigate potential eosinophil-related morbidity and avoid unnecessary drug discontinuation.

INTRODUCTION: Subglottic cysts (SGCs) are a rare cause of laryngeal stenosis that mainly seem to affect preterm infants with an intubation history. PURPOSE: To review the related literature and compare different management protocols for patients presenting SGCs, as well as briefly report our clinical case treated at Verona University Hospital by Pediatric Airways Team. METHODS: The articles resulting from a PubMed and MEDLINE search were analysed and selected using previously established criteria. A systematic review of the selected papers was conducted following PRISMA guidelines. RESULTS: The search yielded 571 related articles; cross-checking of articles led to the identification and exclusion of 239 duplicates. The remaining 332 papers were screened according to previously established eligibility criteria. The final number of selected articles was 13. CONCLUSIONS: Well-planned teamwork, with active collaboration between the ENT specialists, pediatricians and anesthesiologists, is the key to achieve multidisciplinary management of patients diagnosed with SGCs. Long-term follow-up is crucial considering the high recurrence rate of this disease.

Dendritic cells (DCs) initiate adaptive immune responses to cancer cells by activating naive T lymphocytes. 6-sulfo LacNAc(+) DCs (slanDCs) represent a distinct population of circulating and tissue proinflammatory DCs, whose role in cancer immune surveillance is unknown. Herein, by screening a large set of clinical samples, we demonstrate accumulation of slanDCs in metastatic tumour-draining lymph nodes (M-TDLN) from carcinoma patients. Remarkably, slanDCs are absent at the primary carcinoma site, while their selective nodal recruitment follows the arrival of cancer cells to M-TDLN. slanDCs surround metastatic carcinoma deposits in close proximity to dead cells and efficiently phagocytose tumour cells. In colon carcinoma patients, the contingent of circulating slanDCs remains intact and competent in terms of IL-12p70 and tumour necrosis factor alpha production, induction of T-cell proliferation and migratory capacity to a set of chemokines produced in M-TDLN. We conclude that activated slanDCs represent previously unrecognized players of nodal immune responses to cancer cells.
