Abstract
Introduction
Advanced heart failure (AHF) is characterized by repeated episodes of hemodynamic instability, frequent hospitalizations with progressive reduction in quality of life. The aim of the study was to verify in a small group of patients, no longer susceptible to heart transplantation (HT) and left ventricular assistance (LVAD), the effectiveness of monthly treatment with Levosimendan for a period of at least 6 months on quality of life and hospitalization.
Materials and methods
29 elderly patients (≥65 years) with AHF, excluded from the waiting list for HT or no longer eligible for inclusion on the waiting list were enrolled. 12 patients practiced at least 1 infusion of Levosimendan and were considered as cases, while 17 patients with maximized treatment were used as controls. All patients underwent a multidimensional evaluation in which Fraity was assessed according to Fried criteria, cognitive function with Mini-Mental State Examination (MMSE), depressive symptoms with Geriatric Depression Scale (GDS).
Results
The 29 patients were followed up monthly and the 12 patients of Levosimendan group practiced an average of 4.6±2.7 infusions in absence of adverse events. The mean age was 73.3±6.2, 87.5% males, with a NYHA class of 3.4±0.4, an ejection fraction of 26.6±4.9 and NT-pro-BNP value of 7016.8±4876.1. Renal function was impaired with eGFR (ml / min) = 36.8±20.1. These patients had been hospitalized 1.8±0.7 times in the previous year. The data are not statistically different compared to the control group although a greater severity of the clinical condition of the case group is evident. The 6 minute walking test (6MWT) was 201.4±118.1 meters. The mean values of Frailty was 4.6±0.5, the GDS 6.4±4.2 and the MMSE 23.8±4.3. Only the MMSE was lower in the case group than in the controls (26.9±1.9, p=0.022). The results in terms of pre-post treatment difference identify an improvement of 35.3±136.3 meters at 6MWT in patients treated with Levosimendan compared to −72.2±94.2 meters in controls (p=0.030), Frailty is reduced by 1.4±1.6 points compared to 0.1±1.1 in controls (p=0.030), the GDS decreases by 0.9±1.5 in cases and increases by 2±2.1 in the control group (p=0.020), the MMSE score increases by 2.12±4.1 in treated patients, while it is reduced by 2.75±2.3 in the control group; p=0.003. The eGFR is reduced in both groups although more in the controls (−1.87±5.8 vs −10.8±11.1; p=0.043). There are no significant differences in mortality while there was less hospitalization during the follow-up period 0.9±0.6 vs 2.4±1.5; p=0.016). Multiple regression analysis shows that hospitalizations reduction is correlated with the recovery of frailty. This association is independent by age and disease severity.
Conclusion
Levosimendan improves physical and cognitive function, at the same time a minor decrease in renal function is observed, with a reduction of unscheduled visits to the hospital.

[PMID: 34264922 PMCID: PMC8283399 DOI: 10.14639/0392-100x-n1184] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 12/03/2020] [Indexed: 11/23/2022]
Abstract
Objective Chronic suppurative otitis media (CSOM) may result in a serious impairment of the quality of life (QoL). The most relevant characteristics of CSOM are well represented in the “Chronic Otitis Media Outcome Test 15” questionnaire (COMOT-15). The aim of the study was to translate and adapt the COMOT-15 questionnaire into Italian. Methods This is a prospective study conducted on 52 Caucasian Italian-speaking patients with CSOM and 52 controls. The linguistic adaptation of the COMOT-15 consisted of the translation of the English version into Italian and reliability assessment of the translation. Psychometric measurements included internal consistency and test–retest reliability. Results Cronbach’s α was 0.95. The test-retest reliability showed a strong positive correlation for total score and all subscales. Age and gender had no influence on the scores. The correlation between the COMOT-15 and the pure tone average showed a significant association for the scale “Hearing Function”. Conclusions The Italian COMOT-15 questionnaire provides good internal consistency and is suitable for QoL evaluation in Italian-speaking patients suffering from CSOM. In addition, it is able to evaluate the subjective symptoms perceived by patients.

The role of endogenous Antisecretory Factor (AF) in the treatment of Ménière's Disease: A two-year follow-up study. Preliminary results. Am J Otolaryngol 2020; 41:102673. [PMID: 32829060 DOI: 10.1016/j.amjoto.2020.102673] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 07/15/2020] [Accepted: 08/09/2020] [Indexed: 12/11/2022]
Abstract
PURPOSE To evaluate the effects of increased endogenous Antisecretory Factor (AF) synthesis using specially processed cereals (SPC) in a sample of patients with defined unilateral Meniere's disease (MD), compared to the results of a treatment protocol of intravenous glycerol and dexamethasone. MATERIALS AND METHODS Twenty-six patients with unilateral MD were divided in 2 groups and treated with SPC and with intravenous glycerol and dexamethasone for 24 months. Audio-vestibular evaluation was performed before (T0) and every six months. The number of vertigo spells were evaluated before and after therapy and the Efficacy Index (EI) was calculated. Questionnaires for hearing loss, tinnitus and quality of life were administered. RESULTS EI decreased in the SPC group after 18 (T18) (p = .0017) and 24 (T24) months of therapy (p = .0111). There was a significant reduction for tinnitus score in the SPC group at T24 (p = .0131). No significant differences were found between the two groups at T0 (p = .4723), while a significant difference was found at T24 (p = .0027). Quality of life showed a significant improvement in daily activities in the SPC group (p = .0033) compared to the infusion therapy group. No statistically significant changes in PTA thresholds were found in both groups between T0 and T24. CONCLUSION The preliminary results of our study show a significant reduction of vertigo spells and a positive effect on tinnitus severity and on quality of life in patients with unilateral MD treated with SPC and when compared to patients treated with intravenous glycerol and dexamethasone. No effects on hearing thresholds were noted in both groups.

Why Does General QoL Tend to Worsen Over Time Following Septoplasty Even in the Absence of Worsening Nasal Symptoms? Indian J Otolaryngol Head Neck Surg 2020; 74:1134-1137. [DOI: 10.1007/s12070-020-02208-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Accepted: 10/05/2020] [Indexed: 11/25/2022] Open
Abstract
AbstractSeptoplasty is one of the most frequent surgical procedures performed by head and neck surgeons. Despite surgical correction, some patients are not satisfied with their postoperative outcomes. Only a few papers report data on the long-term quality of life of patients after septoplasty, and none over 36 months. This follow up study on 68 surgical procedures aims to evaluate the differences between short term and long-term quality of life after septoplasty using a disease specific quality of life questionnaire, the NOSE, and a general health status questionnaire, the SF-36. We found a statistically significant decrease of the total long-term SF-36 scores, but we did not find changes of the NOSE scores compared with the short-term scores. These results indicated that patients perceived a worsening of their quality of life after more than 36 months following septoplasty, even in the absence of specific nasal symptoms. We could speculate that the preoperative general health performance was erroneously attributed to specific nasal symptoms, probably incorrectly emphasized or that patients did not correctly remember the preoperative clinical status. This research pointed out the importance of patients’ selection and of a thorough evaluation of their preoperative expectations before surgical planning.

Abstract
BACKGROUND Malignant external otitis (MEO) is an invasive infection that can involve the external auditory canal and the skull base up to the contiguous soft tissues. Considering the changing face of MEO, we reviewed cases of MEO treated in our Ear Nose Throat (ENT) clinic - University Federico II of Naples between 2018 and 2019 to evaluate the current epidemiology of the condition and to assess the state of art on diagnosis, therapeutic and follow-up management in our patients. CASE REPORT We present the cases of three male patients with Type 2 diabetes mellitus who complained of long-lasting otorrhea and pain, with clinical suspicion of MEO. In all cases, ear swab was positive for Pseudomonas aeruginosa. All our patients received a 6-week course of intravenous ciprofloxacin, piperacillin, and tazobactam, with rapid clinical symptoms improvement and complete recovery at 1-year follow-up. CONCLUSIONS MEO is difficult to treat due to the lack of standardized care guidelines. Patients with MEO often present with severe otalgia, edema, otorrhea, and facial nerve paralysis. Clinicians must suspect MEO in elderly diabetic and immunocompromised patients with persistent otalgia after external otitis. Imaging (computed tomography and magnetic resonance imaging) can play synergistic roles in the management of MEO. To evaluate eradication of the disease, clinicians have to assess clinical symptoms and signs as well as radiological imaging and inflammatory markers.

Abstract
Skull base osteomyelitis (SBO) is an invasive infection refractory to therapy, closely linked with malignant otitis externa (MOE). It is characterized by a mild clinical presentation that can delay cross-sectional imaging considered as the key to revealing it. Skull base osteomyelitis typically affects elderly diabetics and immunocompromised patients (>70 years). It most commonly has an otogenic origin due to an extension of MOE. The prognosis can be very poor without the administration of adequate and timely therapy at an early disease stage. Nowadays, Pseudomonas aeruginosa remains the most common pathogen associated with SBO. Fungi are a rare cause of MOE. This report documents a rare case of otogenic SBO caused by Candida parapsilosis in a diabetic patient, with persistent otologic symptoms as clinical onset and resistance to medical treatment. Fungal MOE has more subtle symptoms and is more aggressive than its bacterial counterpart. When MOE is resistant to antibacterial drugs, this should raise the suspicion of a fungal etiology of MOE. The current guidelines do not exhaustively describe the diagnosis, antifungal drugs of choice, and optimum duration of treatment. The description of these rare clinical cases should help with the multidisciplinary management of this disease in order to optimize the diagnosis and therapeutic protocol.

A multimodal diagnostic approach to inverted papilloma: Proposal of a novel diagnostic flow-chart. Curr Probl Diagn Radiol 2020; 50:499-504. [PMID: 32540138 DOI: 10.1067/j.cpradiol.2020.04.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2019] [Revised: 03/28/2020] [Accepted: 04/14/2020] [Indexed: 11/22/2022]
Abstract
PURPOSE Inverted papilloma (IP) is a tumor usually arising from sinonasal cavities, with tendency for recurrence and possible malignant transformation. Along with endoscopy, computed tomography (CT) and magnetic resonance imaging (MRI) play a crucial role in defining preoperative staging, tumor origin, and possible differential diagnosis, with significant repercussions on therapeutic planning. However, at present no consensus has been reached concerning IP diagnostic workup. Aim of this study is to assess CT and MRI sensitivity and specificity in identifying IP imaging hallmarks, evaluating their global diagnostic accuracy in order to define a novel diagnostic flowchart. METHODS We retrospectively analyzed multimodal imaging of patients with histologically confirmed IP and mimics. Two neuroradiologists in consensus retrospectively rated the presence of typical imaging features of IP, both on CT and MRI scans. Sensitivity, specificity and diagnostic accuracy were assessed for both the techniques. Final results were expressed as ROC curves and relative areas under the curve (AUC). RESULTS The AUC considering CT parameters were 0.42, whereas the AUC considering MRI parameters were 0.54. Combining the 2 techniques and limiting the evaluation to the most distinctive features such as focal hyperostosis and CCP, the AUC was 0.79. CONCLUSION MRI can provide better tissue characterization and higher diagnostic accuracy in case of suspected IP, whereas CT is more useful in determining bony involvement. Here we propose a possible diagnostic flowchart for IP, based on the assumption that the combination of the imaging techniques allows to optimize the clinical assessment and the subsequent therapeutic planning.

Abstract
PURPOSE Beside the well-known accuracy of non-EPI DWI techniques and relative ADC maps in detecting cholesteatomatous tissue, ADC can also represent a useful tool for stratifying cholesteatoma risk of recurrence. Aim of this study is to test the role of ADC in determining risk of recurrence for primary middle ear cholesteatoma, proposing stratification based on pre-operative mean (mADC) and normalized (nADC) ADC values. METHODS In this prospective study, 60 patients with primary unilateral middle ear cholesteatoma underwent a three-years-long follow-up to assess the presence of recurrent disease after macroscopically complete excisional surgery. Baseline MRI examination mADC and nADC values in the group with early evidence of recurrent cholesteatoma were compared to the group with no evidence of recurrence by using T statistics. RESULTS ADC values on pre-operative MRI examination were lower in cholesteatomas with early evidence of recurrence, and statistical significance was slightly higher for nADC compared to mADC measurements. We also determined a cut-off between the two groups, proposing stratification in high-risk of recurrence cholesteatomas (mADC≤ 1000 or nADC< 1.3) and low-risk cholesteatomas (mADC>1000 or nADC≥1.3). CONCLUSIONS ADC values resulted discriminating in identifying cholesteatomas with higher risk of early recurrence, both for mean and normalized ADC, with optimized tissue characterization and outcome prediction.

Abstract
Introduction: We described a rare clinical case of osteoma associated with homolateral radicular cyst of the maxillary sinus. Observation: Imaging showed two different lesions in the right maxillary sinus. We performed a combined surgical approach to completely remove the lesions and used a plasma rich in growth factors membrane to repair dental roots. No relapse after a 2 years follow-up was observed. Commentaries: The simultaneous presence of two large lesions, a 23,7 mm osteoma and a 33,7 mm radicular cyst in the same maxillary sinus, has been rarely described in the literature. Although nasal endoscopy and imaging are mandatory to assess the diagnosis, the definitive diagnosis was obtained after histopathologic examination. A combined surgical approach allowed a complete removal of both lesions, ensuring, at same time, an optimal surgical field. Plasma rich in growth factors membrane due to its cohesive properties was particularly useful in improving bone neoformation and periodontal regeneration. Conclusion: Diagnostic assessment of maxillary lesions requires nasal endoscopy, imaging and histopathological examination. If these lesions are symptomatic, they should be completely removed and minimally invasive surgery is indicated. Plasma rich in growth factors membrane ensures a good postoperative recovery.

Abstract
PURPOSE Specially processed cereals (SPC) that increase endogenous antisecretory factor (AF) synthesis have been proposed to improve symptoms of Meniere's disease (MD) with controversial results. The aim of this study was to evaluate the effects of SPC in patients with definite unilateral MD and compare the results to a treatment protocol with intravenous glycerol and dexamethasone. METHODS Thirteen patients with unilateral MD were treated with SPC and 13 patients were treated with intravenous glycerol and dexamethasone for 12 months. Audio-vestibular evaluation was performed before (T0) and at the end of the treatments (T12). The number of vertigo spells were evaluated before and after therapy and the Efficacy Index (EI) was calculated. Questionnaires for hearing loss (HHIA), tinnitus (THI) and quality of life (TFL) were administered. RESULTS EI decreased in the SPC group in the second semester compared to the first although not significantly (p = 0.6323). There was a significant reduction for THI score in the SPC group at T12 (p = 0.0325). No significant differences were found between the two groups at T0 (p = 0.4723), while a significant difference was found at T12 (p = 0.0041). Quality of life showed an improvement in daily activities in the SPC group compared to infusion therapy group. CONCLUSION Our study shows a reduced number of vertigo attacks and a positive effect on the discomfort generated by tinnitus and quality of life in patients with unilateral MD treated with SPC and when compared to patients treated with intravenous glycerol and dexamethasone. No effects on hearing thresholds were noted in both groups.

Abstract
Background Cystic fibrosis (CF) is a multisystem disease that involves the upper airways with chronic rhinosinusitis (CRS) causing nasal congestion, rhinorrhea, mouth breathing, facial pain, and olfactory dysfunction. Twelve percent to 71% of CF patients report smelling alterations with an impact on nutrition and quality of life. Objectives The goal was to study olfaction performance in CF patients with CRS that worsens quality of life. Methods A total of 121 subjects were enrolled in this study. Seventy-one had CF and underwent ear, nose, and throat evaluation with nasal endoscopy, sinonasal outcome test 22 (SNOT-22), visual analog scale (VAS), and “Sniffin’ Sticks.” Fifty subjects were age-matched with healthy controls. Results All 71 CF patients were affected by CRS; 59 of 71 (83.1%) had CRS without nasal polyps and 12 of 71 (16.9%) had CRS with early nasal polyps. None of the 50 controls had CRS. Total SNOTT-22 mean values in the 71 CF patients were 38.10 ± 21.08 points. If considering only the 59 CF patients without nasal polyps, the SNOTT-22 mean value was 36.76 ± 21.52 points. Moreover, based on the VAS scores, the degree of nasal symptoms was classified as mild for facial pain, smell alteration, nasal discharge, and sneezing and resulted in moderate symptoms for nasal blockage and headache. Among the CF patients, 55 of 71 (76.5%) declared to be normosmic, while the smelling ability assessed by “Sniffin’ Sticks” showed that only 4 of 71 (5.63%) were normosmic, 58 (81.69%) were hyposmic, and 9 (12.68%) were anosmic. In the controls, 41(82%) were normosmic, 9 (18%) were hyposmic, and none were reported to be anosmic ( P < .001). Conclusions We confirm that most CF patients have a relevant olfactory impairment, although only a low percentage declares such alteration. A careful evaluation with simple and rapid tests helps to select the patients who may benefit from specific therapies.

Septoplasty: is it possible to identify potential "predictors" of surgical success? ACTA ACUST UNITED AC 2019; 38:528-535.

Abstract
Septoplasty is one of the most frequent surgical procedures performed by otolaryngologists. Despite successful surgical correction, many patients are not satisfied with their outcomes. So far, in clinical practice there is no consensus of opinion about the reliability of objective measurements of nasal patency and the correlation between objective measurements and subjective nasal patency symptoms. This study aims to assess the reasons for patient dissatisfaction after septoplasty and optimise pre-operative diagnostic management to predict surgical outcomes. We analysed 494 patients undergoing septoplasties with turbinoplasty by subjective Nasal Obstruction Symptom Evaluation questionnaire (NOSE) and objective active anterior rhinomanometric measurements before surgery and after 6 months. In our series, 17% had postoperative septal re-displacement; all patients had an anterior deviations at baseline. We found that the type of septal deviation, anterior vs posterior, was a significant predictor of postoperative functional improvement, whereas demographic characteristics as age, gender and smoke habit were not. Our data suggest that the anterior segment of the nasal septum was the most critical area for nasal airway resistance and more difficult to manage because it is likely to re-displace vs the posterior one and for this reason it represents a negative predictor of postoperative satisfaction.

Abstract
The discovery that miRNAs are frequently deregulated in tumours offers the opportunity to identify them as prognostic and diagnostic markers. The aim of this multicentric study is to identify a miRNA expression profile specific for laryngeal cancer. The secondary endpoint was to identify specific deregulated miRNAs with potential as prognostic biomarkers for tumour spread and nodal involvement, and specifically to search for a miRNA pattern pathognomonic for N+ laryngeal cancer and for N- tissues. We identified 20 miRNAs specific for laryngeal cancer and a tissue-specific miRNA signature that is predictive of lymph node metastases in laryngeal carcinoma characterised by 11 miRNAs, seven of which are overexpressed (upregulated) and four downregulated. These results allow the identification of a group of potential specific tumour biomarkers for laryngeal carcinoma that can be used to improve its diagnosis, particularly in early stages, as well as its prognosis.

Abstract
PURPOSE To diagnose cholesteatoma when it is not visible through tympanic perforation, imaging techniques are necessary. Recently, the combination of computed tomography and magnetic resonance imaging has proven effective to diagnose middle ear cholesteatoma. In particular, diffusion weighted images have integrated the conventional imaging for the qualitative assessment of cholesteatoma. Accordingly, the aim of this study was to obtain a quantitative analysis of cholesteatoma calculating the apparent diffusion coefficient value. So, we investigated whether it could differentiate cholesteatoma from other inflammatory tissues both in a preoperative and in a postoperative study. METHODS This study included 109 patients with clinical suspicion of primary or residual/recurrent cholesteatoma. All patients underwent preoperative computed tomography and magnetic resonance imaging with diffusion sequences before primary or second-look surgery to calculate the apparent diffusion coefficient value. RESULTS We found that the apparent diffusion coefficient values of cholesteatoma were significantly lower than those of non cholesteatoma. In particular, the apparent diffusion coefficient median value of the cholesteatoma group (0.84 × 10- 3 mm2/s) differed from the inflammatory granulation tissue (2.21 × 10- 3 mm2/s) group (p < 2.2 × 10- 16). Furthermore, we modeled the probability of cholesteatoma by means of a logistic regression and we determined an optimal cut-off probability value of ~ 0.86 (specificity = 1.0, sensitivity = 0.97), corresponding to an apparent diffusion coefficient cut-off value of 1.37 × 10- 3 mm2/s. CONCLUSIONS Our study has demonstrated that apparent diffusion coefficient values constitute a valuable quantitative parameter for preoperative differentiation of cholesteatomas from other middle ear inflammatory diseases and for postoperative diagnosis of recurrent/residual cholesteatomas.

Abstract
Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the cystic fibrosis transmembrane regulator (CFTR) gene. About 2000 mutations have been described so far. We setup an ex vivo model of human nasal epithelial cells (HNECs) to study CF patients testing the effect of novel mutations and molecular therapies. We performed sampling (by brushing), followed by culture and analysis of HNECs using a series of molecular techniques. We performed 50 brushings from CF patients and controls. Using cultured cells, we: i) demonstrated the widely heterogeneous CFTR expression in patients and in controls; ii) defined the splicing effect of a CFTR mutation; iii) assessed the CFTR gating activity in patients bearing different mutations; iv) demonstrated that butyrate significantly enhances CFTR expression. Based on our data, we can conclude: 1) HNEC brushing is performed without anaesthesia and is well tolerated in all CF patients (children and adults); 2) HNECs can be preserved for up to 48 hours before culture allowings multicentre studies; 3) HNECs culture can be considered a suitable model to study the molecular effects of new CFTR gene mutations and/or uncertain meaning specific mutations of carriers; 4) an ex vivo model of HNECs may be used to evaluate, before human use, the effect of new drugs on patients’ cells bearing specific CFTR mutations; 5) the methodology is adequate for a quantitative measurement, by fluorescence, of the CFTR gating activity of the HNECs from patients with different genotypes identifying: a) CF patients bearing two severe mutations with an activity < 10% (compared to controls – 100%); b) CF patients bearing at least a mild mutation with an activity of 10-20%; c) CF carriers (heterozygous subjects) with an activity between 40-70%.

ADC Benchmark Range for Correct Diagnosis of Primary and Recurrent Middle Ear Cholesteatoma. BIOMED RESEARCH INTERNATIONAL 2018; 2018:7945482. [PMID: 29854790 PMCID: PMC5941773 DOI: 10.1155/2018/7945482] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Revised: 02/02/2018] [Accepted: 03/20/2018] [Indexed: 12/18/2022]
Abstract
OBJECTIVES Magnetic resonance imaging (MRI) and in particular diffusion-weighted imaging (DWI) have been broadly proven to be the reference imaging method to discriminate between cholesteatoma and noncholesteatomatous middle ear lesions, especially when high tissue specificity is required. The aim of this study is to define a range of apparent diffusion coefficient (ADC) values within which the diagnosis of cholesteatoma is almost certain. METHODS The study was retrospectively conducted on a cohort of 124 patients. All patients underwent first- or second-look surgery because primary or secondary acquired cholesteatoma was clinically suspected; they all had preoperative MRI examination 15 days before surgery, including DWI from which the ADC maps were calculated. RESULTS Average ADC value for cholesteatomas was 859,4 × 10-6 mm2/s (range 1545 × 10-6 mm2/s; IQR = 362 × 10-6 mm2/s; σ = 276,3 × 10-6 mm2/s), while for noncholesteatomatous inflammatory lesions, it was 2216,3 × 10-6 mm2/s (range 1015 × 10-6 mm2/s; IQR = 372,75 × 10-6 mm2/s; σ = 225,6 × 10-6 mm2/s). Interobserver agreement with Fleiss' Kappa statistics was 0,96. No overlap between two groups' range of values was found and the difference was statistically significant for p < 0.0001. CONCLUSIONS We propose an interval of ADC values that should represent an appropriate benchmark range for a correct differentiation between cholesteatoma and granulation tissue or fibrosis of noncholesteatomatous inflammatory lesions.

Abstract
This study analysed the immunohistochemical expression of the CAF-1/p60 protein in laryngeal cancers. CAF-1/p60 assumes an independent discriminative and prognostic value in laryngeal neoplasms; the presence of this protein in carcinoma in situ compared with laryngeal precancerous and larynx infiltrating tumours. We assessed the immunohistochemical expression of CAF-1/p60 in 30 cases of moderate and/or severe dysplasia, 30 cases of carcinoma in situ and 30 cases of laryngeal squamous cell carcinoma (LSCCs). CAF-1/p60 expression increased significantly according to the high index of neoplastic cellular replication; therefore, CAF-1/p60 was overexpressed in neoplastic cells and its moderate-severe expression is correlated with poorer prognosis compared to less expression. In conclusion, overexpression of the CAF-1/p60 protein is related to a risk of higher morbidity and mortality and is a reliable independent prognostic index of laryngeal carcinoma. CAF1-p60 protein overexpression can be used in cancer management as an indicator of malignant evolution, especially in carcinoma in situ.

In Vivo Biofilm Formation, Gram-Negative Infections and TAS2R38 Polymorphisms in CRSw NP Patients. Laryngoscope 2018; 128:E339-E345. [PMID: 29570813 DOI: 10.1002/lary.27175] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 01/22/2018] [Accepted: 02/12/2018] [Indexed: 01/11/2023]
Abstract
OBJECTIVES Among the predisposing factors implicated in the immune response to airway bacterial infections, genetic variations of the bitter taste receptor TAS2R38, which is expressed in the cilia of the human sinonasal epithelial cells, seem to be associated with susceptibility to chronic rhinosinusitis (CRS) and in vitro biofilm formation. Polymorphisms in TAS2R38 generate two common haplotypes: the nonfunctional AVI (Alanine, Valine, Isoleucine) and the functional PAV (Proline, Alanine, Valine) alleles, with the latter protecting against gram-negative sinonasal infections. The aim of this study is to investigate for the first time the relevance of TAS2R38 genetic variants in the susceptibility to bacterial infections associated with in vivo biofilm formation in chronic rhinosinusitis with nasal polyps (CRSwNP) patients. STUDY DESIGN A prospective study on 100 adult patients undergoing functional endoscopic sinus surgery (FESS) for CRSwNP. METHODS Propylthiouracile (PROP) testing and TAS2R38 genotyping were applied to characterize patients for receptor functionality. Sinonasal mucosa samples were processed for microbiological examination and biofilm detection. RESULTS The nonfunctional genotype is more frequent among CRS patients than in the general population (25% vs. 18.4%, P = 0.034). Airway gram-negative infections are primarily associated with the AVI haplotype (88.9% vs. 11.1% PAV/PAV-functional genotype, P = 0.023). Biofilm formation is prevalent in CRS patients with the AVI nontaster phenotype (62.5% vs. 33.3% PAV taster or supertaster phenotype, P = 0.05). CONCLUSION Our findings confirm an inverse correlation between TAS2R38 functionality and gram-negative infections in Italian patients with CRSwNP. In addition, for the first time we demonstrated a relationship between in vivo microbial biofilm and TAS2R38 receptor variants. LEVEL OF EVIDENCE 2b. Laryngoscope, 128:E339-E345, 2018.

Abstract
Background Right insular cortex is involved in taste discrimination, but its functional organization is still poorly known. In general, sensory cortices represent the spatial prevalence of relevant features for each sensory modality (visual, auditory, somatosensory) in an ordered way across the cortical space. Following this analogy, we hypothesized that primary taste cortex is organized in similar ordered way in response to six tastes with known receptorial mechanisms (sweet, bitter, sour, salt, umami, CO2). Design Ten normal subjects were enrolled in a pilot study. We used functional magnetic resonance imaging (fMRI), a high resolution cortical registration method, and specialized procedures of feature prevalence localization, to map fMRI responses within the right insular cortex, to water solutions of quinine hydrochloride (bitter), Acesulfamate K (sweet), sodium chloride (salt), mono potassium glutamate + inosine 5' mono phosphate (Umami), citric acid (sour) and carbonated water (CO2). During an fMRI scan delivery of the solutions was applied in pseudo-random order interleaved with cleaning water. Results Two subjects were discarded due to excessive head movements. In the remaining subjects, statistically significant activations were detected in the fMRI responses to all tastes in the right insular cortex (p<0.05, family-wise corrected for multiple comparisons). Cortical representation of taste prevalence highlighted two spatially segregated clusters, processing two and three tastes coupled together (sweet-bitter and salt-umami-sour), with CO2 in between. Conclusions Cortical representation of taste prevalence within the right primary taste cortex appears to follow the ecological purpose of enhancing the discrimination between safe nutrients and harmful substances.

Abstract
The planning of experimental studies for evaluation of nasal airflow is particularly challenging given the difficulty in obtaining objective measurements in vivo. Although standard rhinomanometry and acoustic rhinometry are the most widely used diagnostic tools for evaluation of nasal airflow, they provide only a global measurement of nasal dynamics, without temporal or spatial details. Furthermore, the numerical simulation of nasal airflow as computational fluid dynamics technology is not validated. Unfortunately, to date, there are no available diagnostic tools to objectively evaluate the geometry of the nasal cavities and to measure nasal resistance and the degree of nasal obstruction, which is of utmost importance for surgical planning. To overcame these limitations, we developed a mathematical model based on Bernoulli's equation, which allows clinicians to obtain, with the use of a particular direct digital manometry, pressure measurements over time to identify which nasal subsite is obstructed. To the best of our knowledge, this is the first study to identify two limiting curves, one below and one above an average representative curve, describing the time dependence of the gauge pressure inside a single nostril. These upper and lower curves enclosed an area into which the airflow pattern of healthy individuals falls. In our opinion, this model may be useful to study each nasal subsite and to objectively evaluate the geometry and resistances of the nasal cavities, particularly in preoperative planning and follow-up.

Abstract
Folate deficiency may be directly associated with carcinogenesis. Folate supplementation may reduce the risk of progression in a mucosa that is already genetically altered. The aim of the present study was to determine the role of folic acid in the treatment of mild and moderate laryngeal dysplasia recurring after surgery. The data obtained by laryngoscopy, measurement of serum folate levels and functional vocal assessment with the GIRBAS scale and VHI questionnaire were compared in patients who had received folic acid with a homogeneous group of patients with dysplasia who had not undergone any therapy. A total of 24 patients suffering from recurrence of mild or moderate laryngeal dysplasia (n=12, group A) were treated with 400 mg folic acid per os, once daily for 6 months. The patients in group B (n=12) received no treatment and were used as the control group. In group A, 7 (58%) patients exhibited a complete response, with clinically evident regression of leukoplakia, 3 (25%) displayed a partial decrease in the lesions with reduced volume of the area involved, whereas 2 patients exhibited no change. As regards patients in control group B, 8 (67%) exhibited no change, in 1 case there was a spontaneous regression, and in 3 (25%) there was disease progression with suspected malignant transformation, leading to repeat surgery. Therefore, folate deficiency may be considered to be a factor predisposing to precancerous lesions, and dietary folate supplementation may prevent and reduce the emergence of cancer.

Abstract
BACKGROUND Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells outside bone marrow. It accounts for 4% of all non-epithelial sinonasal tumors. According to the literature, radiotherapy is the standard therapy for extramedullary plasmacytoma. However, the conversion rate of extramedullary plasmacytoma to multiple myeloma is reported to be between 11 and 33% over 10 years. The highest risk of conversion is reported during the first 2 years after diagnosis, but conversion has been noted up to 15 years after diagnosis. Once conversion to multiple myeloma is complete, less than 10% of patients will survive 10 years. CASE PRESENTATION We present three cases of sinonasal extramedullary plasmacytoma who underwent radiotherapy: a 61-year-old white man, a 60-year-old white man, and a 37-year-old white woman. We found long-term survival with stable disease in all three cases. CONCLUSIONS The management of solitary extramedullary plasmacytomas of the sinonasal tract is not well established yet. However, the possibility of recurrence and progression to multiple myeloma requires a thorough follow-up protocol. Due to the absence of a standardized protocol for these tumors, we tried to design a tailored long-term follow-up scheme.

Abstract
Sino-nasal solitary extramedullary plasmacytoma (EMP) is a rare neoplasm with unpredictable progression to multiple myeloma. To improve the precision of irradiation delivery, preserving the healthy surrounding tissue and critical structures we used a CyberKnife® for the treatment of sinonasal solitary extramedullary plasmacytoma. We present the first case of sinonasal-EMP treated with CyberKnife®-stereotactic radiotherapy (SRT) with a complete remission without adverse events. Based on the post-therapeutic results and healthy tissue preservation, we believe that CyberKnife®-SRT represents a good therapeutic option for the treatment of sinonasal-EMP.

Abstract
Epidermal cysts are benign tumors derived from the epidermis or the epithelial hair follicle filled with keratin and lipid-rich debris, typically occurring in areas with a high-density of sebaceous glands. These cysts commonly occur on the face, scalp, neck and trunk, where the sebaceous glands are more active. Their localization within the bone is extremely uncommon. The current study details the case of a 24-year-old male who presented with right otorrhea and ipsilateral hypoacusia having undergone right overlay myringoplasty for subtotal eardrum perforation. This patient represents a rare case of an epidermal cyst localized in the temporal bone (the fifth described in English-language literature), which may be considered as a complication of myringoplasty.

Abstract
BACKGROUND This study evaluates endoscopic and quality of life (QoL) outcomes in two groups, composed by both allergic (A) and non-allergic (N-A) adolescents undergoing septoplasty with concurrent turbinate surgery by radiofrequency treated after surgery with nasal spray containing liposomes and vitamins A and E. METHODS This double-blind randomized study was carried out on 40 patients (22 males, 18 females, mean age 15.5±1.0 years) undergoing septoplasty and volumetric tissue reduction of inferior turbinates by radiofrequency for post-traumatic deformities and severe nasal obstruction. We enrolled 20 subjects with positive skin prick tests and 20 with negative skin prick tests (SPT) to aeroallergens. All subjects underwent the Visual Analogue Scale (VAS) questionnaire and the nasal endoscopy score by Lund and Kennedy (LK) at baseline before surgery (T0) and 15 days (T15) and 21 days (T21) after treatment. After surgery, the nose was not packed and the day after surgery all subjects were randomized into two groups, experimental arm group I (GI) and control arm group II (GII) and given the treatment, nasal spray containing liposomes composed of phospholipids, fatty acids, and vitamin A and E for group I and saline solution (sodium chloride 0.9%) for group II. RESULTS After therapy, the VAS and LK scores were better (P<0.05) in the investigational than in the control arm in both sub-groups (A and N-A). CONCLUSIONS Our findings suggested that liposomal, vitamins A and E nasal spray improves the QoL in the early postoperative period, both in A and N-A sub-groups.

Abstract
Granulocytic sarcoma (GS) is a rare extramedullary manifestation of acute myeloid leukemia (AML). GS may develop simultaneously to AML or as a relapse of leukemia, particularly following allogeneic hematopoietic stem cell transplant. Subperiosteal bone, lymph nodes and skin are commonly involved, whereas rhinopharyngeal involvement is less common, with only 14 cases reported in the literature. Due to its rarity, rhinopharyngeal GS may lead to diagnostic pitfalls, particularly when it is poorly differentiated or is without concomitant marrow involvement. Thus, immunohistochemical findings play a key role in diagnosis. The current report describes a case of a 53-year-old female suffering from rhinopharyngeal GS and with a history of AML treated with chemotherapy and radiotherapy, focusing on the importance of the immunohistochemical pattern to assess the right diagnosis. Recent studies have demonstrated that the immunophenotype is of utmost importance for the diagnosis of GS. The high expression of myeloperoxidase (MPO) is common in GS; however, ~30% of GSs do not contain MPO. Therefore, the presence of other markers is required to confirm the diagnosis of GS.

Abstract
BACKGROUND Available medical treatments for chronic rhinosinusitis (CRS) with nasal polyposis (CRSwNP) comprise systemic and topical therapies. Although topical corticosteroids are effective in the treatment of CRS, they are not completely devoid of adverse effects. Thus, care has to be taken when long-term treatments are prescribed. There is recent evidence that sodium hyaluronate (SH), the major component of many extracellular matrices, promotes tissue healing, including activation and moderation of the inflammatory responses, cell proliferation, migration, and angiogenesis. OBJECTIVE The aim of the study was to evaluate clinical outcomes and quality of life in two groups of patients with CRSwNP treated with topical corticosteroids alone or in combination with 9 mg of high-molecular-weight SH. METHODS The impact of treatments was determined by using nasal endoscopy and validated quality of life questionnaires (Short Form-36, 22-item Sino-Nasal Outcome Test, visual analog scale [VAS]). Eighty subjects who had CRS with grade IV nasal polyposis: 40 diagnosed with allergic rhinitis (AR) and 40 with non-allergic-eosinophilic rhinitis (NARES) based on skin-prick test and nasal cytology results, were divided in two groups. Group I comprised 40 subjects (20 AR and 20 NARES), who received mometasone furoate plus SH; group II comprised 40 subjects (20 AR and 20 NARES), who received mometasone furoate plus saline solution alone. All the patients were followed up for 3 months. RESULTS At baseline, no statistically significant differences were observed between the groups and the VAS score showed a moderate-to-severe degree of disease. After treatments, Lund and Kennedy, Short Form-36, 22-item Sino-Nasal Outcome Test, and VAS scores were statistically significant in both groups but slightly in favor of the group I and in the subjects with allergic CRSwNP. CONCLUSION Analysis of our data indicated that an SH supplement to standard corticosteroid seems to play an important role in improving the severity of symptoms, the endoscopic appearance, and discomfort associated with CRSwNP. This effect seems to be strongest in patients with allergic CRSwNP.

Abstract
In Kallmann syndrome (KS), congenital hypogonadism is associated with olfactory impairment. To evaluate flavor perception-related disability in KS patients, 30 patients with KS, 12 with normosmic hypogonadism (nIHH), 24 with acquired anosmia (AA), and 58 healthy controls entered the study. All participants completed questionnaires concerning dietary habits, olfaction-related quality of life (QoL), and self-determined olfactory, flavor, and taste abilities prior to undergoing standardized olfactometry and gustometry. Each subject underwent flavor testing, using orally administered aqueous aromatic solutions, identifying 21 different compounds by choosing each out of 5 alternative items. Flavor score (FS) was calculated as the sum of correct answers (range 0-21). Flavor perception by self-assessment was similar between KS, nIHH, and controls, and was mostly reduced only in AA. FS was similar between KS (5.4 ± 1.4) and AA (6.4 ± 1.9), and lower than in nIHH (16.2 ± 2.4, p < 0.001) and controls (16.8 ± 1.7, p < 0.0001). FS showed strong reproducibility, and correlated with olfactory scores in the overall population. KS and AA patients identified aromatics eliciting trigeminal stimulation better than pure odorants. Olfaction-related QoL was more impaired in AA than in KS. We report significant flavor impairment in KS. This contrasts with routine clinic evidence; KS patients, in contrast with AA, do not complain of flavor perception impairment, perhaps owing to the congenital nature of the dysfunction. Flavor perception impairment should be considered a specific KS disability, because of important detrimental effects on physical and mental health and on QoL. KS patients should also be advised of this impairment in order to prevent accidental and life-threatening events.

Abstract
The aim of this prospective, randomised study was to evaluate the effects of nasal douches with sodium hyaluronate on clinical and endoscopic variables, on parental perception of their childs health-related quality of life (HR-QoL), and on parental workdays lost in preschool recurrent upper respiratory tract infections (URTIs). Children aged 2-6 years with recurrent or persistent URTIs underwent at baseline the evaluation of upper respiratory tract symptoms in the previous two weeks, and nasal endoscopy. Parents of enrolled children were assessed for self-perception of their childrens HR-QoL using a standardised questionnaire. The same variables were reassessed after a 2-week treatment with either 9 mg sodium hyaluronate plus saline solution or saline alone by nasal douches. Forty of the 48 children enrolled completed the study (22 assigned to the combined treatment). Compared to baseline, the combined treatment resulted in a significant reduction of the prevalence of children with missed daycare days (45% vs 14%, p=0.04) and of parents with workdays lost (36% vs 5%, p=0.02), and in a significant improvement of HR-QoL score (3.7 vs 2.8, p=0.004). At endoscopy, the secretion and mucosal oedema score significantly improved after the combined treatment (6 vs 2, p < 0.001), and there was a trend towards a reduction of the adenoid hypertrophy score (p=0.06). No clinical, HR-QOL or endoscopy changes were found in the saline group. In preschool children with recurrent or persistent URTIs, sodium hyaluronate by nasal douche significantly improves endoscopic features. Additional benefits include the childrens HR-QoL and daycare attendance, and parental work.

Abstract
Chronic rhinosinusitis (CRS) determines irreversible alterations of the nasal mucosa with consequent impairment of ciliary movements and, therefore, mucociliary clearance (MCC). People of all ages can be affected by CRS but the elderly are subjects at the highest risk. CRS in the elderly with an age-related physiological impairment of nasal respiratory function, often accompanied by other chronic diseases, requires additional therapies to be added to the numerous daily medications. Since the currently available therapies for CRS include the use of drugs that can have adverse effects and contraindications, crenotherapy could represent a therapeutic option. Indeed, because the adverse effects and contraindications of crenotherapy are scarce, it can be safely used in elderly patients with comorbidities. The aim of this study is to evaluate the nasal cytological assessment after crenotherapy in elderly subjects with CRS. Two groups, comprising a total of 84 elderly subjects with CRS, were treated with crenotherapy with sodium chloride sulphate hyperthermal water rich in mineral salts (group I, n=49) and saline solution (group II n=35). Cytological assessment for both groups took place at baseline (T0) and 1 month after treatment (T30). At T30 the nasal cytological assessment showed statistically significant improvements in the ciliary motility and in the count of neutrophils and spores in group I, but not in group II. Conversely, there were no significant differences in the count of eosinophils, mast cells, bacteria and biofilm in either group. Our data for the first time focused on the role of crenotherapy in the improvement of cytological assessment of CRS in the elderly.

Olfactory performance after crenotherapy in chronic rhinosinusitis in the elderly. Laryngoscope 2015; 125:1529-34. [PMID: 25639589 DOI: 10.1002/lary.25173] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2014] [Revised: 12/17/2014] [Accepted: 12/31/2014] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To evaluate the effectiveness of crenotherapy on the olfactory performance of elderly patients with chronic rhinosinusitis (CRS). STUDY DESIGN A longitudinal case-control study of a cohort of elderly patients affected by CRS and olfactory dysfunction assessed with the Sniffin' Sticks (Burghart Medical Technology, Wedel, Germany) (SS) olfactory test. METHODS One hundred and thirty-seven elderly subjects with CRS were divided into two groups. The investigational arm (n = 69) underwent crenotherapy with hyperthermal water, rich in mineral salts, and the control group (n = 68) underwent NaCl 0.9% both for 12 days. At baseline and at 1 and 6 months after treatment, both groups underwent ear nose and throat assessment and SS. Self-report questionnaires were administered at baseline to evaluate the patients' own olfactory response, and after treatment to evaluate their degree tolerability. Olfactory performance was then evaluated in elderly subjects with hyposmia without CRS (n = 40) and in younger subjects with both hyposmia and CRS (n = 40). RESULTS No adverse reactions were reported after crenotherapy. The SS total score showed that crenotherapy induced a statistically significant improvement in the olfactory function of both the elderly and the younger subjects with hyposmia and CRS. By contrast, no improvement was observed in the control arm and in the elderly with hyposmia without CRS. All subjects showed a good degree of tolerability. CONCLUSIONS We demonstrated that crenotherapy effectively improves olfactory function in elderly patients with CRS. Finally, our study suggests that crenotherapy represents a safe therapeutic strategy for the treatment of CRS and olfactory dysfunction in the elderly.

Abstract
Adenoid cystic carcinoma (ACC) or ‘cylindroma’ is a malignant tumor that often occurs in the areas of the head and neck, affecting the secretory glands and the major and minor salivary glands. The present study describes a case of a patient who presented with a posterior tongue lesion. The case is of a 71-year-old female with an asymptomatic volume growth of the posterior left tongue perceived 8 months prior, and neoplastic cells positive for c-kit. A computed tomography of the head and neck showed asymmetry of the base of the tongue, which was enlarged in the left portion. A physical examination revealed a nodule on the posterior left tongue of ~3 cm in diameter, while the cervical lymph node chain had a normal size and consistency. Surgical exeresis of the tongue lesion and cervical lymph node dissection were performed. Subsequent to surgical removal of the cancer cells and adjuvant radiotherapy, the patient showed excellent health, although the follow-up remains in progress. ACC, one of the most biologically destructive tumors of the head and neck, is locally aggressive and gives rise to distant metastases. The tongue is the place of origin in 3.4–17.1% of cases. The treatment for ACC consists of primary surgical resection with adjuvant radiotherapy. To prevent the risk for distant metastasis, it is necessary to remove the first echelon nodes and monitor the patient with a long-term follow-up.

Impact of intranasal sodium hyaluronate on the short-term quality of life of patients undergoing functional endoscopic sinus surgery for chronic rhinosinusitis. Int Forum Allergy Rhinol 2014; 4:484-7. [PMID: 24591296 DOI: 10.1002/alr.21310] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2013] [Revised: 12/21/2013] [Accepted: 01/28/2014] [Indexed: 11/10/2022]
Abstract
BACKGROUND Functional endoscopic sinus surgery (FESS) has become the treatment of choice for patients with medically resistant chronic rhinosinusitis (CRS) and nasal polyps. Despite the consolidated use of different treatments, the postoperative period is often very painful and uncomfortable, especially during the first month. Although evidence on the effectiveness of sodium hyaluronate (SH) on postoperative care following FESS is available, data on the quality of life (QoL) from the patients' perspective are still lacking. This study aimed to evaluate for the first time the effectiveness of nasal douche with SH in reducing patients' discomfort during the first month following FESS. METHODS A double-blind randomized controlled study was carried out on 124 subjects undergoing FESS for CRS with nasal polyposis. They were divided into 2 groups: group I was treated with nasal douche containing 9 mg of high molecular weight SH plus saline solution and group II was treated with saline solution alone. To assess QoL in CRS patients, the Short Form-36 (SF-36) test, the Sino-Nasal Outcome Test-22 (SNOT-22), and the visual analogue scale (VAS) questionnaires were administered. RESULTS At baseline, there were no statistically significant differences between the 2 groups. However, after 30 days of long postoperative treatments, we found clinically significant improvements in QoL of subjects treated with SH, as evidenced by all QoL scales. CONCLUSION Our data indicate that SH significantly improves patients' short-term QoL following FESS in terms of both general health and specific sinonasal status.

Abstract
Little is known about how CO2 affects neural processing of taste. We used functional magnetic resonance imaging to investigate the effects of carbonation on brain processing of sweet stimuli, which has relevance to studies of food selection and satiety. The presence of carbonation produced an overall decrease in the neural processing of sweetness-related signals, especially from sucrose. CO2 reduced the neural processing of sucrose more than that of artificial sweeteners. These findings might be relevant to dietary interventions that include noncaloric beverages, whereas the combination of CO2 and sucrose might increase consumption of sucrose.

Abstract
Anomalous proliferation of the cholesteatoma epithelium is caused by extrinsic factors such as toxins or bacterial antigens combined with lytic enzymes, lymphokines and cytokines released from the inflammatory infiltrate. This could explain the close relationship between the aggressiveness of cholesteatoma and repeated bacterial superinfection, therefore it is very important to know the bacteria involved in order to control the regrowth of skin following surgery, reduce the aggressive potential of the cholesteatoma and limit the incidence of complications. This study focused on 70 females and 80 males aged between 15 and 65 years, affected by cholesteatomatous otitis media; all underwent bacteriological examination of the auricular secretion. The floral bacteria which proved to play the most important role (60.3%) were the aerobic type and the highest levels were those of Pseudomonas aeruginosa (31.1%) followed by Staphylococcus aureus (19.1%), Proteus mirabilis (7.7%), Escherichia coli (1.4%) and Klebsiella pneumoniae (1%). Anaerobic floral bacteria were found in a fairly high percentage of cases (38.2%); in particular, anaerobic gram-positive cocci (Peptococcus 12.4% and Peptostreptococcus in 4.8% of cases), Bacteroides (12.4%), Clostridium (3.8%), Fusobacterium (2.9%) and Propionobacterium (1.9%) were isolated. In 3 cases of mycetes (1.4%) only Aspergillus, in association with Pseudomonas and Staphylococcus, was identified. The study showed, then, how effective second generation fluoroquinolones and third generation cephalosporins are (the latter being used in pre-adolescent children), the reason being that these antibiotics work not only on Pseudomonas and Staphylococcus, but also on the anaerobic bacteria.

Abstract
Clear cell carcinoma (CCC) of the larynx is a rare pathological finding; only eight cases are described in the literature. It occurs in older adults and shows a predilection for men. We report the ninth observation of laryngeal CCC in the literature. We reviewed the literature and correlated the prognosis of the tumour according to its site of onset and treatment. The literature review showed that this neoplasm is highly aggressive, with a high recurrence rate and short mean survival time; the treatment of choice is surgery, and chemo- or radiotherapy are used mainly for the treatment of recurrences.

Abstract
Data from personal case histories, from 1984 to 2000 inclusive, are reported in order to contribute to a better understanding of some of the clinical and epidemiological ENT associated TB aspects. Analysis of these data shows that: (1) Like the pulmonary form, ENT localizations are increasing due to the traditional risk factors (immigration, poverty, immunodeficiency, drug addiction). (2) They are generally clinically primitive forms (which are found in extrapulmonary regions as the first expression of tubercular disease) and typically affect young people with a slight prevalence among females. Lymph gland localizations are the most frequent.

Abstract
Stapedotomy for otosclerosis presents particular anaesthesiology demands as the surgeon has to assess functional results during the operation, work with some bleeding, be ensured the collaboration of the patient, and limit the occurrence of intra- and post-operative symptoms (dizziness, nausea, vomiting and pain). Remifentanyl, a micro-opioid selective agonist characterised by short latency and duration, has been used for about 2 years at the Otolaryngological Unit of the "Federico II" University of Naples for patients with otosclerosis undergoing stapedotomy. Aim of the study was, therefore, to assess: efficacy and tolerability of Remifentanyl in combination with a local anaesthetic in surgical procedures for otosclerosis; intra- and post-operative reduction in patient symptoms of dizziness, nausea, vomiting and pain; reduction of intra-operative bleeding; degree of patient collaboration and optimisation of anaesthesiological and vital parameters monitored during surgery. The study was carried out on 92 patients with otosclerosis, (17 M, 75 F), median age 41 years (range 25-56), undergoing stapedotomy. Patients were randomly assigned to one of two groups, which were homogeneous as far as concerns age, sex and pre-operative hearing: i. Group A (50 patients), received Remifentanyl infusion in combination with canal injection for local anaesthesia with Mepivacaine 2% and Adrenalin 1/100,000; ii. Group B (42 patients), received only local anaesthetic by infiltration of the external canal ear. Remifentanyl led to an improvement over the local anaesthetic technique previously used, with a clear decrease in intra- and post-operative neurovegetative symptoms such as dizziness, nausea, vomiting and pain, as well as reduced bleeding.

Abstract
The authors have conducted a study of a large sampling of subjects who had undergone different types of cordectomy. The purpose of this study has been to analyze the anatomo-functional variables encountered with such procedures. In particular, the following were studied: post-surgical vocal recovery; type of glottic sphincter scarring, particularly as related to the extent of surgical excision; effect commissure synecchia has on the post-operative voice, again related to type of exeresis; different types of functional compensation related to the various surgical excisions and means by which the new scarring cord is built; severity of dysphonia resulting after each type of surgery. The study involved 69 patients who had undergone different types of cordectomy: from limited procedures--the so-called submucosal cordectomies for circumscribed, superficial neoplasms--to more radical ones, performed on tumours extending to the laryngeal ventricle of one or both sides. A history was taken of all the cases and they underwent videolaryngoscopy, psychoacoustic evaluation and voice spectrography. This study revealed the following: vocal recovery is achieved within 1-3 months after surgery, particularly when the exeresis was limited; longer recovery times were required for more radical surgery; with horizontal exeresis the prognosis for sphincteric recovery--characterized by a good neocord--is better than with procedures removing structures on the vertical plane (true vocal cord + ventricle + false cord) where scarring generally proves inadequate to re-establish a satisfactory sphincter; commissure synecchia is unusual in all types of surgery and is more frequent in bilateral forms. This is not specifically responsible for aggravating the dysphonia although, except in a few cases, it can make an important contribution in limiting the glottic opening and facilitating vocal sounds; as regards functional compensation, the observations show that the larynx is able to adapt to anatomic damage, the entire organ playing a part in reducing the air space to create a more or less valid phonatory sphincter, each part in its own way. Among the most noteworthy mechanisms for functional compensation we find the cord-neocord, the glottic mechanism at the false cords and ary-arythenoid compensation. There is no direct relationship between phonatory mode and neocord conformation since not all cases achieving a satisfactory neocord actually use glottic phonation. Although the Yanagihara spectrographic classification of dysphonia cannot distinguish between severe dysphonia and aphonia, it can be applied in the objective classification of limited post-cordectomy vocal compromise. In fact, spectrography is able to document that: Type II dysphonia--light--is unusual and was only found in 2 cases with a excellent neocord and a perfect pneumo-phonic picture; Type II dysphonia--moderate--is most often found in submucosal cordectomies and in other cases of monolateral exeresis with adequate scarring; Type IV dysphonia actually corresponds to the most important forms. It is present in all types of cordectomy and is most prevalent in those with a severe adductor deficit associated with inadequate or poorly balanced supraglottic functional compensation.

Abstract
The authors present a study of 37 patients affected by monolateral vocal cord paralysis in order to analyze etiology, degree of dysphonia and possible recovery of vocal function. The patients underwent the following tests: case history to determine the vocal characteristics prior to the lesion; video-laryngoscopy to define the position of the paralytic cord on the horizontal glottic plane and any compensation mechanisms; determination of the degree of dysphonia (light, moderate, severe, aphonia) on the basis of psycho-perceptive parameters; spectrography evaluated in classes (I, II, III and IV) according to Yanagihara. Analysis of the data obtained makes it possible to draw the following conclusions: the most frequent etiology encountered by the otorhinolaryngologist is surgical (particularly subsequent to thyroidectomy); the position taken by the paralytic vocal cord does not appear to determine the degree of dysphonia; during the period immediately after occurrence of the lesion (0-4 months) the vocal disorder is more intense and tends to be reduced thereafter, attenuated by a spontaneous compensation mechanism. In this regard, it must be pointed out, however, that such compensation can prove bad or even dangerous for good vocal function (falsetto voice); speech therapy makes it possible to nearly totally normalize vocal function in all patients presenting moderate dysphonia and in 60% of those with severe dysphonia. In the remaining 40% of those patients with severe dysphonia a partial improvement of vocal function was seen (from severe dysphonia to moderate dysphonia). This was determined by the fact that several negative prognostic factors came into play simultaneously in these patients (i.e. advanced age, longer time gap since the lesion occurred, position assumed by the paralytic cord) which prevented them from achieving better phonatory results.

Abstract
Logopedic therapy is proposed in helping cordectomized patients learn to best use pneumo-phonal structures to compensate for the glottic insufficiency often resulting from this type of surgery. Rehabilitation showed be initiated as soon as possible following surgery before the patients starts using compensation mechanisms negative for voice quality. However, precisely those patients often receive therapy tardively when the anatomo-functional results have already been consolidated and the voice quality is poor. The rehabilitation discussed uses classical feed back mechanisms through which the subjects learn to recognise those factors which enable them to better their voice quality. The type of exercises to be employed depends on whether or cordectomy extended to the ventricle and to false vocal cord. On the farmer case, the principle aim of therapy is that of nearing the healthy vocal cord to the neocord through appropriate exercises. On the better case, instead, the main vocal compensation is the result of the perfect coordination of expiratory energy and the activity of the healthy vocal cord. In fact, in extended cordectomized patients, in the light of the modest amount of scarring, it is necessary to cause the healty voice cord to shift entirely towards and beyond the median line as to as compensate for a sphincteric loss. The authors report two clinical case, particularly difficult from a rehabilitation point of view, in which, relatively speaking, in light of the initial voice conditions, satisfactory results were obtained.

Abstract
Cordectomies usually result in alteration of the glottic sphincter which in turn effects the activity of the entire larynx bringing about different types of dysphonia according to the resulting scarring pattern in the glottic floor and to the functional recompensation made by the cordectomized patients themselves. Today, study of those anatomic dynamics which determine voice typology in cordectomized patients is possible thanks to various means: synthesis of data obtained from psycho-perspective analyses of the vocal product, video-fiber-laryngoscopic observation of the vocal tract and spectrographic study. The above-mentioned examinations show how the type of dysphonia in these patients is determined by the various combinations of different scarring patterns, which also depend on the entity of surgical exeresis, and the position taken on by various laryngeal district during phonation? The authors present paradigmatic clinical cases in order to demonstrate the different phonatory capabilities achieved by patients who had undergone either cordectomy or cordectomy extended to the ventricle and false vocal cords.
