RESUMEN
BACKGROUND: Redox imbalance and inflammation have been proposed as the principal mechanisms of damage in the auditory system, resulting in functional alterations and hearing loss. Microglia and astrocytes play a crucial role in mediating oxidative/inflammatory injury in the central nervous system; however, the role of glial cells in the auditory damage is still elusive. OBJECTIVES: Here we investigated glial-mediated responses to toxic injury in peripheral and central structures of the auditory pathway, i.e., the cochlea and the auditory cortex (ACx), in rats exposed to styrene, a volatile compound with well-known oto/neurotoxic properties. METHODS: Male adult Wistar rats were treated with styrene (400 mg/kg daily for 3 weeks, 5/days a week). Electrophysiological, morphological, immunofluorescence and molecular analyses were performed in both the cochlea and the ACx to evaluate the mechanisms underlying styrene-induced oto/neurotoxicity in the auditory system. RESULTS: We showed that the oto/neurotoxic insult induced by styrene increases oxidative stress in both cochlea and ACx. This was associated with macrophages and glial cell activation, increased expression of inflammatory markers (i.e., pro-inflammatory cytokines and chemokine receptors) and alterations in connexin (Cxs) and pannexin (Panx) expression, likely responsible for dysregulation of the microglia/astrocyte network. Specifically, we found downregulation of Cx26 and Cx30 in the cochlea, and high level of Cx43 and Panx1 in the ACx. CONCLUSIONS: Collectively, our results provide novel evidence on the role of immune and glial cell activation in the oxidative/inflammatory damage induced by styrene in the auditory system at both peripheral and central levels, also involving alterations of gap junction networks. Our data suggest that targeting glial cells and connexin/pannexin expression might be useful to attenuate oxidative/inflammatory damage in the auditory system.

Different studies have tried to establish a relationship between dyslexia and the vestibular system function. Subjective Visual Vertical/Horizontal (SVV and SVH) and Video Head Impulse Test (VHIT) are useful for studying the vestibular system and can be easily performed in children. Our aim was to evaluate the vestibular function in dyslexic children by SVV/SVH and VHIT. We enrolled 18 dyslexic children (10M/8F; mean age 10.7 ± 2.3 years; range 7-14 years) and 18 age-matched children with typical development of learning abilities. All children performed VHIT, SVV and SVH. We found normal gain and symmetry of vestibulo-ocular-reflex both in dyslexic and typically developing children. Fifteen out of 18 dyslexic children (83.3%) showed a difference of at least one amongst SVV or SVH. The mean value of SVV was 2.3° and the mean value of SVH was 2.6°. Statistical analysis showed a significant difference between typically developing and dyslexic children for both SVV and SVH. We confirm a relationship between dyslexia and the alteration of SVV and SVH. Our results could be related to the pathogenetic hypothesis of a visual processing impairment related to a dysfunction of the magnocellular pathway or to a general deficit related to a multimodal cortical network.

BACKGROUND: Metastatic lesions to the salivary gland are rare and mostly affect the parotids. Metastases represent 8% of all malignant lesions of the parotid gland. Around 80% originate from squamous cell carcinomas (SCC) of the head and neck region. Fine needle aspiration (FNA) plays a crucial role in distinguishing primary salivary gland lesions from metastases. Herein we describe our series of metastases to the parotid glands. MATERIALS AND METHODS: We analysed 630 parotid gland FNAs over a decade including conventional and liquid-based cytology specimens. Ancillary techniques such as immunocytochemistry (ICC) were conducted on cell blocks. RESULTS: Eighty (12.4%) cases were malignant lesions, of which 53 (63.75%) were metastases including 24% melanoma, 22.6% SCC, 19% renal carcinomas, 7.5% breast carcinomas, 11.3% lung, 9% intestinal and 1.8% testicular, malignant solitary fibrous tumour and Merkel cell carcinoma. The 53 cases, classified according to the Milan system for salivary cytopathology, belonged to 5 Suspicious for malignancy (SFM) and 48 malignant (M) categories. Forty had a known history of primary malignancy (75.4%), while 13 were suspicious to be a metastatic localisation (24.5%), distributed as 5SFM (2SCC and 3Melanoma) and 8 M. A combination of clinical history, cytomorphology and ICC identified 100% of them. CONCLUSIONS: Fine needle aspiration plays a central role in the diagnostic workup of patients with metastatic lesions to their parotid glands, thereby defining the correct management. Diagnostic accuracy may be enhanced by applying ICC. Although melanoma and SCC are the most common histological types, several other malignancies may also metastasize to the parotid glands and should be kept into consideration.

PURPOSE: Aim of this study was to calculate the percentage of the Automatic Speaking Valve (ASV) use in a large cohort of laryngectomized patients with voice prosthesis (VP) and to analyze the main reasons for non-use. Subsequently, a specific rehabilitation training was proposed. METHODS: One hundred-ten laryngectomized patients with VP were enrolled in the first phase of the study (census). Among them, 57 patients were included in the second phase (intervention), in which a training based on moving phonatory exercises was proposed. Structured questionnaires were used before and after training in order to investigate ASV use rate (days/week and hours/day; reasons for impeding the ASV use), average adhesive life-time during ASV use; hands-free speech duration; skin irritation. Patients also expressed their degree of on a VAS scale from 0 to 100. RESULTS: In the census phase the percentage of use of ASV (everyday, without problems) was equal to 17.27% (19/110 patients). The main causes of disuse concerned excessive fatigue and poor durability of the adhesives. The analysis of the results pre vs. post-training showed a statistically significant increase (p < 0.05) in all the investigated parameters. Patients reported a good level of treatment compliance (average frequency of performing exercises equal to 4.2 ± 2.5 days/week for 1.4 ± 1.01 h/day) and high degrees of satisfaction. After treatment, the percentage of use of AVS increased by 43% reaching a rate of 60% (66/110 patients). CONCLUSION: A specific and targeted approach that simulate the phonatory and breathing difficulties of everyday life can increase the ASV usage rate.

PURPOSE: Induced eosinophilia is commonly related to dupilumab treatment. We analysed the temporal trends of blood eosinophilia in patients with severe uncontrolled CRSwNP during the first year of treatment with dupilumab in real-life setting to evaluate its correlation with outcomes of response and adverse events (AEs). METHODS: Seventy-four patients with severe uncontrolled CRSwNP treated with dupilumab at our institution were enrolled. At each visit, we evaluated AEC, outcomes of response to treatment and AEs. RESULTS: A significant increase in AEC was observed since the first month with a peak at 3 months; at 12 months, the values returned comparable to those at baseline. A ≥ 50% increase of the baseline AEC with a value greater than 500 cells/mm3 was documented in 38/74 patients (Group A) regardless of the time of observation, whereas in 36/74 patients (Group B), no changes were observed. Analysing the blood eosinophilia trend over time in group A, we observed a temporary eosinophilia with early onset (within 6 months), persistent eosinophilia with early onset, and eosinophilia with late onset. No differences in terms of outcomes of response to treatment or AEs were found between Group A and Group B, or between patients who developed an AEC ≥ 1500 cells/mm3 or not. CONCLUSION: In our series, we observed that an increase in AEC with different temporal trends may be observed in CRSwNP patients during the first year of treatment with dupilumab. In our series, eosinophilia is not correlated with a negative outcome of response to treatment or a risk of AEs.

INTRODUCTION: Management of severe chronic rhinosinusitis with nasal polyps (CRSwNP) has changed significantly in recent years, with different treatments now available including biologics and endoscopic sinus surgery (ESS), although there are still few comparative studies. We aimed to compare 1-year outcomes of patients with severe CRSwNP treated with dupilumab or ESS plus intranasal corticosteroids (INCS). METHODS: In this retrospective, real-life, observational, cohort study, we enrolled 101 patients with severe CRSwNP who were treated with INCS and either ESS (n = 49) or dupilumab (n = 52). The following outcomes were considered: nasal polyp score (NPS), Sino Nasal Outcome Test-22 (SNOT-22), visual analogue scale (VAS) for specific symptoms, Sniffin' Sticks identification test (SSIT), need for oral corticosteroids (OCS) and local eosinophilia detected by nasal cytology. RESULTS: ΔNPS was significantly higher in the surgery group up to 12 months when the difference with dupilumab group was no longer significant (ΔNPS: 4 vs. 4.1). ΔVAS rhinorrhoea, ΔVAS smell and ΔSNOT-22 were significantly higher in the dupilumab group at 12 months (p < .05). SSIT scores were significantly better in the dupilumab group starting from the first month of follow-up (p < .05). In the dupilumab group, only 6.1% of patients had detectable local eosinophilia compared to 57% in the surgery group alongside with a lower need for OCS (16.3% vs. 61%). CONCLUSIONS: Both dupilumab and ESS were effective in improving outcomes in patients with severe CRSwNP over 12 months. Nevertheless, patients treated with dupilumab had greater improvement in terms of SNOT-22, VAS rhinorrhoea, VAS smell and SSIT scores, with better control of local inflammation and less need for OCS.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is associated with significant morbidity and reduced health-related quality of life. Findings from clinical trials have demonstrated the effectiveness of dupilumab in CRSwNP, although real-world evidence is still limited. METHODS: This Phase IV real-life, observational, multicenter study assessed the effectiveness and safety of dupilumab in patients with severe uncontrolled CRSwNP (n = 648) over the first year of treatment. We collected data at baseline and after 1, 3, 6, 9, and 12 months of follow-up. We focused on nasal polyps score (NPS), symptoms, and olfactory function. We stratified outcomes by comorbidities, previous surgery, and adherence to intranasal corticosteroids, and examined the success rates based on current guidelines, as well as potential predictors of response at each timepoint. RESULTS: We observed a significant decrease in NPS from a median value of 6 (IQR 5-6) at baseline to 1.0 (IQR 0.0-2.0) at 12 months (p < .001), and a significant decrease in Sino-Nasal Outcomes Test-22 (SNOT-22) from a median score of 58 (IQR 49-70) at baseline to 11 (IQR 6-21; p < .001) at 12 months. Sniffin' Sticks scores showed a significant increase over 12 months (p < .001) compared to baseline. The results were unaffected by concomitant diseases, number of previous surgeries, and adherence to topical steroids, except for minor differences in rapidity of action. An excellent-moderate response was observed in 96.9% of patients at 12 months based on EPOS 2020 criteria. CONCLUSIONS: Our findings from this large-scale real-life study support the effectiveness of dupilumab as an add-on therapy in patients with severe uncontrolled CRSwNP in reducing polyp size and improving the quality of life, severity of symptoms, nasal congestion, and smell.

Endoscopic transsphenoidal surgery is a novel surgical technique requiring specific training. Different models and simulators have been recently suggested for it, but no systematic review is available. To provide a systematic and critical literature review and up-to-date description of the training models or simulators dedicated to endoscopic transsphenoidal surgery. A search was performed on PubMed and Scopus databases for articles published until February 2023; Google was also searched to document commercially available. For each model, the following features were recorded: training performed, tumor/arachnoid reproduction, assessment and validation, and cost. Of the 1199 retrieved articles, 101 were included in the final analysis. The described models can be subdivided into 5 major categories: (1) enhanced cadaveric heads; (2) animal models; (3) training artificial solutions, with increasing complexity (from "box-trainers" to multi-material, ct-based models); (4) training simulators, based on virtual or augmented reality; (5) Pre-operative planning models and simulators. Each available training model has specific advantages and limitations. Costs are high for cadaver-based solutions and vary significantly for the other solutions. Cheaper solutions seem useful only for the first stages of training. Most models do not provide a simulation of the sellar tumor, and a realistic simulation of the suprasellar arachnoid. Most artificial models do not provide a realistic and cost-efficient simulation of the most delicate and relatively common phase of surgery, i.e., tumor removal with arachnoid preservation; current research should optimize this to train future neurosurgical generations efficiently and safely.

INTRODUCTION: The aim of this case series was to evaluate the necrosis of teeth adjacent to the site of mandibulotomy or mandibulectomy in a cohort of patients suffering from head and neck cancers. METHODS: Fourteen patients who underwent segmental mandibulectomy or paramedian mandibulotomy for oral, oropharynx or major salivary gland cancer and a total of 23 teeth were included in this case series. Twelve patients underwent adjuvant head and neck radiotherapy. Cold sensitivity pulp testing and/or electric pulp testing were performed on teeth at the margin of mandibulectomy and on teeth adjacent to mandibulotomy after surgery. A "positive" response was considered the healthy state, and "negative" was considered the diseased state of the tooth. RESULTS: The 10 patients who underwent mandibulotomy had 12 teeth with a negative response. The 4 patients treated by mandibulectomy had two positive and three negative responses to cold and electric pulp tests. Fifteen out of 23 teeth (65.2%) showed a negative response to sensitivity testing. CONCLUSIONS: Tooth necrosis seems to be a common event after mandibulectomy and mandibulotomy. CLINICAL RELEVANCE: To avoid post-surgery complications, performing root canal therapy before surgery on the teeth adjacent to the surgical site could be an appropriate strategy.

PURPOSE OF REVIEW: Non-allergic rhinitis (NAR) includes different subtypes, among which NAR with eosinophilia syndrome (NARES) is the most important because of severity of symptoms and the high risk of comorbidities. Its pathophysiology is still object of debate, but a crucial role of chronic eosinophilic inflammation has been recognized. The aim of this review is to critically analyze the current evidence regarding the hypothesis that NARES may be considered a type 2 inflammatory disorder. RECENT FINDINGS: The definition and diagnostic criteria for NARES are not universally shared and adopted, thus generating difficulties in reproducing the results. At present, there is extreme heterogeneity in sampling methods and disagreement in the cut-off of local eosinophilic count to determine a diagnosis of NARES. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standard was applied to identify English-language experimental and clinical articles regarding NARES. The search was performed in April 2021. Twenty-six articles were included. Our data suggest a particular heterogeneity regarding sampling and specific cut-offs adopted for diagnosis of NARES and consensus should be reached. We suggest that eosinophil count should be reported as an absolute value for at least 10 observed rich fields in order to increase the level of standardization. Consensus among authors on this topic should be reached with particular attention to the cut-off for diagnosis. In the future, this limitation may be overcome by the identification of repeatable biomarkers to refine diagnosis and prognosis of NARES. Furthermore, our data strongly suggest that NARES have numerous similarities with clinical features of the most common type 2 diseases such as eosinophilic asthma and chronic rhinosinusitis with nasal polyps (CRSwNP): late onset, association with type 2 comorbidities, selective eosinophilic tissue infiltration, remarkable response to oral and intranasal corticosteroids, and progression in a type 2 CRSwNP.

PURPOSE: Irreversible bilateral sensorineural hearing loss is a common side effect of platinum compounds. Because of the extended overall survival, a prolonged hearing surveillance and management of hearing impairments are emerging concerns for pediatric oncology. METHODS: In this retrospective observational study, we enrolled 38 children out of 116 treated at our institution by chemotherapy (cisplatin and/or carboplatin) with or without irradiation between 2007 and 2014, submitted to hearing monitoring before every cycle of chemotherapy, and who completed a 5-year long-term audiological follow-up. Chemotherapy regimens, demographic findings, cumulative doses, and cranial irradiation were compared. RESULTS: At the end of 5-year follow-up, ototoxicity was significantly increased compared to that observed at the end of chemotherapy (52.5% vs 39.5%, p < 0.001). A late onset of hearing loss was experienced in 13.1% of children, while in 26.3% progressive hearing loss was measured. Deafness at the end of chemotherapy and irradiation were significant prognostic factors for late ototoxicity outcomes (Odds Ratio 7.2-CI 1.67-31.1-p < 0.01 and 5.25-CI 1.26-21.86-p < 0.01 respectively). No significant differences were found between cisplatin and combined treatment (i.e., cisplatin shifted to carboplatin during monitoring for the onset of ototoxicity) and ototoxicity was not associated with platinum compounds cumulative dose (p > 0.05). 13.1% of children needed hearing aids at the end of follow-up. CONCLUSION: Long-term monitoring of at least 5 years prevents the harmful effects of hearing deprivation identifying late onset/progressive hearing loss after platinum compound chemotherapy in children thanks to early hearing rehabilitation, especially in those who underwent multimodal therapy or subjected to irradiation.

OBJECTIVES: We aim to analyse long-term voice outcomes and quality of life (QoL) in patients undergoing open partial horizontal laryngectomy type II (OPHL type II) and to compare them to those obtained by patients undergoing total laryngectomy (TL) with voice prosthesis (VP). DESIGN: Cross-sectional cohort study. SETTING: Patients undergoing surgery for advanced laryngeal cancer, assessed during the usual follow-up consultations at the Phoniatric Unit (February 2020-December 2020). PARTICIPANTS: Forty-five patients were enrolled and divided into two groups: OPHL group and TL group. MAIN OUTCOMES MEASURES: Acoustic analysis, maximum phonation time, INFV0 scale, I-SECEL, UW-QoL-V4 and MDADI questionnaires were used to assess the long-term outcomes. RESULTS: Voices of patients undergoing OPHL Type II were worse than those of laryngectomised patients with VP. Nevertheless, scores in voice and dysphagia-related QoL were comparable and scores in the social domain of QoL were higher in OPHL group. CONCLUSIONS: Open partial horizontal laryngectomy Type II allows an acceptable voice recovery and a satisfactory QoL.

BACKGROUND: Allergic rhinitis is a common childhood disease responsible for a major impact on quality of life and healthcare resources. Many hypotheses have been proposed to explain the link between allergy and otitis media, although a definitive mechanism has not been identified yet. One of the major critical points is that authors failed in distinguishing among different phenotypes of middle ear inflammation. This review pointed out literature evidence from the laboratory and clinical experience linking allergy to different phenotypes of otitis media in children. METHODS: We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process. Our search yielded 3010 articles that were finally screened. This resulted in 20 manuscripts of which the full texts were included in a qualitative analysis. We paid particular attention in distinguishing among phenotypes of otitis media. RESULTS: Clinical evidence and analyses of biomarkers suggested that allergy may be linked to some phenotypes of otitis media and, in particular, to otitis media with effusion (OME) and acute re-exacerbations in children with middle ear effusion. It was not possible to perform the analysis for allergy and acute and chronic otitis media because of paucity and heterogeneity of data. CONCLUSION: Allergy should be considered in the diagnostic workup of children with OME as well as OME should be excluded in children with persistent moderate to severe AR. In these cases, clinicians should evaluate prompt and accurate treatment of allergy in improving outcomes, although futures studies are required to increase evidence supporting that anti-allergy treatment may be effective in the recovery and outcome of otitis media with effusion.

OBJECTIVE: Fine needle aspiration cytology (FNAC) is a well-established diagnostic procedure for head and neck masses not clearly originating from mucosal or cutaneous surfaces. We analysed head and neck masses evaluated over a 2-year period, to assess the reliability of FNAC for the evaluation of malignancy. METHODS: We enrolled all patients undergoing FNAC, from April 2013 to July 2015, in a single service of a large Italian university hospital. Relevant clinical data and ultrasonographic parameters of the lesions were recorded. We performed both conventional and thin-prep smears. Clinical presentation, ultrasonographic features and final cytology diagnoses were analysed and correlated with histology. RESULTS: The series included 301 lesions in 285 patients, with a single (94.4%) or two (5.6%) lesions. Only eight samples were considered non-diagnostic/inadequate (2.6%). Among the cases, 139 FNAC (46.1%) underwent surgery. Cytological-histological correspondence was found in 89% of the cases. Concerning malignancy, we documented less than 4% false positives and less than 2.5% false negatives, with 92.7% sensitivity and 94.6% specificity. CONCLUSION: FNAC diagnosis can be highly specific. Most importantly, it is highly reliable in assessing malignancy, thus defining the priority and guiding the management procedures.

Dysphagia is common in tracheostomized patients who underwent head and neck surgery for cancer treatment. The objective of this study was to evaluate, by means of oropharyngoesophageal scintigraphy (OPES), the impact of an occluded tracheal tube (TT) on swallowing in patients treated for head and neck cancer before hospital discharge, to provide further information to the benefit of out-patient care management. From October 2018 to November 2019, we enrolled 19 tracheostomized patients (6 females and 13 males; mean age 61 years) who underwent primary surgical resection of head and neck tumor and swallowing rehabilitation during hospitalization. All subjects underwent a double-standard OPES, one with occluded tracheal tube and the other without TT, with their tracheal stoma being closed directly by a plaster. For each study, we assessed and compared the following quantitative parameters: oral transit time (OTTsec), pharyngeal transit time (PTTsec), esophageal transit time (ETTsec), oral retention index (ORI%), pharyngeal retention index (PRI%), esophageal retention index (ERI%), and aspiration percentage (AP%). The mean values of OTT, PTT, ORI%, PRI%, and ERI% were abnormal during OPES both with TT and without TT and did not statistically differ between the two tests (p > 0.05). Aspiration was detected in 4 cases out of 19 (21.05%) cases during OPES with TT and in 4/19 (21.05%) cases without TT who showed a mean AP% of 11.4% and 11.5% respectively (p > 0.05). Patients with abnormal AP% (> 0%) during OPES with TT showed aspiration signs without TT. Our study showed that the mere presence of a closed tracheal tube does not impact significantly the oropharyngeal transit of bolus during swallowing. This result suggests the possibility to maintain a small-diameter occluded tracheal tube in place for the postsurgical management of head and neck cancer patients.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vestibular vertigo, with post-traumatic origin in about 15% of cases. Management and prognosis of traumatic BPPV (T-BPPV) are still debated, especially about recurrence. The aim was to compare T-BPPV to idiopathic (I-BPPV). DESIGN AND STUDY SAMPLE: We analysed data about 795 BPPV patients: 716 idiopathic (90%) and 79 post-traumatic (10%), evaluating clinical history and bedside-examination, treating all patients with repositioning manoeuvres and reassessing them until the resolution of symptoms and nystagmus. RESULTS: Persistence rate in T-BPPV and I-BPPV patients was significantly different (p = 0.0074, OR = 2.31), respectively 12.6% and 5%. Also the rate of bilateral disease (p = 0.0063, OR = 4.72) and multicanalar involvement (p = 0.0183; OR = 4.67) were significantly higher in T-BPPV patients . There were no significant differences in age and sex distribution, side and canal interested. In T-BPPV group, the resolution rate with one manoeuvre was lower than I-BPPV (p = 0.0132: OR: 0,56). Recurrence rate was 38% in the T-BPPV group and 30.6% in the I-BPPV group, without significant difference. CONCLUSIONS: T-BPPV resulted different from I-BPPV in the resolution rate, bilateral or multiple canal involvement and persistence rate. T-BPPV and I-BPPV does not differ for recurrence rate, suggesting that, after resolution, the natural course of post-traumatic and idiopathic BPPV is similar.

OBJECTIVES: The primary end point of this study was to evaluate the impact of bile acids on severity of laryngo-pharyngeal reflux (LPR) and the possible correlation with esophagitis and upper airway malignancies. The second end point was to evaluate if salivary bile acids and molecules other than pepsin might serve as diagnostic biomarkers of LPR. DESIGN: Observational prospective comparative study. SETTING: Otorhinolaryngology unit of a tertiary hospital. PARTICIPANTS: Sixty-two consecutive adult outpatients suspected of LPR. MAIN OUTCOME MEASURES: Bile acids, bilirubin and pepsinogen I-II were measured in saliva. Patients underwent pH metry and based on the results of bile acids were subdivided as acid, mixed and alkaline LPR. RESULTS: Significantly higher Reflux Findings Score (RFS) and Reflux Symptoms Index (RSI) were seen in patients with alkaline and mixed LPR compared to acid LPR. Salivary bile acids >1 µmol/L seem to be a reliable indicator of the severity of LPR. Compared to those without, patients with esophagitis or a history of upper airway malignancy have high concentrations of bile acids in saliva. Among the molecules studied, bile acids were the most suitable for diagnosis of LPR, with a sensitivity of 86% and a positive predictive value of 80.7%. CONCLUSIONS: Our data suggest that high concentrations of bile acids are associated with higher values of RSI and RFS in LPR as well as a higher risk of esophagitis and history of upper airway malignancies. We finally observed that bile acids provided the best biometric parameters for diagnosis of LPR among the molecules tested.

PURPOSE OF THE REVIEW: We provide a systematic review of experimental and clinical evidences linking allergy to acute, including common cold, and chronic rhinosinusitis in children. Furthermore, we questioned if anti-allergy treatment may prevent the occurrence of rhinosinusitis or improve outcomes of its specific management. RECENT FINDINGS: Allergic rhinitis is a common childhood disease in industrialized countries that is responsible for a major impact on quality of life and healthcare resources. Over the years many authors tried to correlate allergy with comorbidities and in particular to the onset of rhinosinusitis including common cold, even though conflicting results are frequently reached. We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process. Our search yielded 7103 that were finally screened. This resulted in 25 publications of which the full texts were assessed and included in a qualitative analysis per different phenotypes of rhinosinusitis. The evidence suggests that allergy may lead to overall impairment of mechanical and immunological defense function of the nasal mucosa against viruses and that anti-allergy treatment may significantly decrease the number and severity of upper respiratory tract infections including common colds in children. It was not possible to perform the analysis for allergy and post-viral acute rhinosinusitis, bacterial acute rhinosinusitis, and recurrent acute rhinosinusitis because of paucity and heterogeneity of data. Although there is no definitive proof of causation linking allergy to chronic rhinosinusitis, studies lead to suppose that anti-allergy treatment may improve outcomes of specific CRS treatments.

PURPOSE: The objective of this study is to analyse the relationship between the endoscopic signs of laryngo-pharyngeal reflux, the lingual tonsil hypertrophy (LTH) and its inflammation, adopting Narrow Band Imaging (NBI) technology. METHODS: We enrolled, as cases, patients with clinical diagnosis of laryngopharyngeal reflux disease (LPRD), a Reflux Symptom Index (RSI) ≥ 13, and a Reflux Finding Score (RFS) ≥ 7. Controls were enrolled among patients who underwent the same transnasal endoscopy, equipped with NBI, with a RSI < 13 and a RFS < 7. Nasopharynx, Lingual Tonsils (LT), Hypopharynx and Larynx were evaluated by two experienced otolaryngologists, who calculated the Reflux Finding Scale (RFS) score and focused their attention on the base of the tongue, observing its surface with NBI technology. RESULTS: 82 patients with diagnosis of laryngopharyngeal reflux were enrolled as cases. Mean RFS was 11.7 (SD = 2.9). As controls, we enrolled 80 patients. Mean RFS was 2.7 (SD = 1.63). We found that RFS positivity was associated with a significant increase in LT dimension (2.5 vs 1.1, p < 0.001), with a higher LT crypt inflammation grading (1.8 vs 0.09, p < 0.001) and with a higher Roman Cobblestone pattern grading (1.48 vs 0.11, p < 0.001). A significant correlation between the crypt inflammation and the hyperemia subscore of RFS was present (r = 0.696, p < 0.0001), while it was not possible to find a correlation between crypt inflammation and either diffuse laryngeal edema (r = 0.166, p = 0.135) and posterior commissure hypertrophy (r = 0.089, p = 0.427). CONCLUSIONS: NBI allowed us to identify endoscopically the presence of enlarged lingual tonsil, crypt inflammation and superficial mucosal changes, in patients affected by LPRD. LEVEL OF EVIDENCE: 2 (prospective, case-control study).
