Abstract
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.

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%.

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.

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
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
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.

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
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.
