Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide, accounting for approximately 6% of all cancer cases and responsible for an estimated 1-2% of all cancer deaths. Much research evidence has accumulated in the recent years on the changes in the expression of pro-inflammatory and, to a lesser extent, anti-inflammatory cytokines, that (i) may have a role in the malignant transformation of HNSCC, (ii) may be used as diagnostic markers in the sera of patients because of their excessive production by the tumor cells and (iii) may act as possible immunotherapeutic targets. Among pro-inflammatory cytokines, interleukin-8 (IL--8) has been reported to have an important role in cancer invasion, angiogenesis and metastasis. Recent studies have shown an increased concentration of IL--8 in patients with HNSCC and a positive association with lymph node metastasis and tumor classification, although IL--8 was not significantly associated with shorter overall survival and cancer progression-free survival. Additional evidence on the pathological mechanism of origin, invasion, and metastasis of HNSCC, as well as a better understanding of the implications of cytokines, chemokines and growth factors, are of paramount importance for the advancement of research in head and neck oncology.

Abstract
OBJECTIVE The aim of this review is to describe the most common recurring and chronic upper respiratory tract infections (URTI) in children and discuss the role of bacterial interference and bacteriotherapy in their prevention and treatment. MATERIALS AND METHODS A literature review has been performed on the following topics: acute otitis media, adenoiditis, tonsillitis, rhinosinusitis, microbiotics and the role of bacterial interference, and bacteriotherapy in the prevention and treatment of URTI. RESULTS Research studies into the characteristics of the microbiological flora and its role in the pathogenesis of URTI have focused on a single pathogen, on resistance to and ineffectiveness of antibiotic therapies, or on the persistence of bacterial biofilm. Recent evidence supports a central role of the existing microbial ecosystem in the pathogenesis of respiratory disease. In light of this, new therapeutic approaches include the implantation and persistence within the normal microflora of relatively innocuous "effector" bacteria that can competitively exclude or prevent the outgrowth of potentially disease-causing bacteria. Recently, a retrospective and observational study demonstrated that S. salivarius 24SMB and S. oralis 89a nasal spray could be effective in the prevention of recurrent otitis media in a real-life setting. Other studies have focused on the role of bacteriotherapy in children with beneficial effects in the prevention of URTI. CONCLUSIONS The results of previous studies on the role of bacteriotherapy in paediatric URTI suggest that the use of bacterial interference phenomena through bacteriotherapy is a feasible, safe approach and deserves proper consideration as a promising therapeutic strategy against URTI.

Abstract
OBJECTIVE Childhood obstructive sleep disordered breathing (SDB) is a sleep-related upper airway obstruction that degrades sleep quality, ventilation and/or oxygenation; obstructive sleep apnea syndrome (OSAS) is one of the most common causes of SDB in children. The aim of this review is to evaluate the role of the anesthesiologist in pediatric OSAS. MATERIALS AND METHODS A literature review has been performed on the following topics: clinical aspects of pediatric OSAS, preoperative investigations including questionnaires, clinical parameters, laboratory polysomnography and home sleep apnea testing, anesthesiologic preoperative management, anesthesiologic perioperative management, anesthesiologic postoperative management including postoperative analgesia, postoperative nausea and vomiting (PONV), and post-tonsillectomy bleeding. RESULTS OSAS in children is a distinct disorder from the condition that occurs in adults; adenoidectomy and tonsillectomy are the first line of therapy in these patients. Even if these surgical procedures are frequently performed, they represent a great challenge for surgeons and anesthesiologists and are associated with a substantially increased risk of morbidity and mortality. CONCLUSIONS The role of the anesthesiologist is pediatric OSAS is crucial before, during and after surgery, as pediatric patients are at higher risk of preoperative, perioperative and postoperative adverse events including airway obstruction, PONV, and bleeding.

Abstract
Abstract
Background
Patients with cancer are at higher risk of atrial fibrillation (AF) compared with the general population. Furthermore, cancer per se and anti-cancer treatments have been associated with thromboembolic complications and increased bleeding risk. Considering that only 12% of cancer patients can achieve a stable International Normalized Ratio target and the frequent need for invasive procedures, warfarin is not an ideal option. Direct oral anticoagulants may theoretically represent a valid alternative although their use in this population has been scarcely investigated.
Purpose
To compare efficacy and safety of direct oral Xa inhibitors (DOXaI) versus warfarin in patients with atrial fibrillation and cancer.
Methods
We searched electronic databases for randomized controlled trials (RCTs) that analyzed the use of DOXaI versus warfarin in patients with AF and cancer. The primary efficacy outcome was stroke or systemic embolism (SE). The secondary efficacy outcomes were ischemic stroke, myocardial infarction and all-cause death. The primary safety outcome was major bleeding; secondary safety outcomes were major or clinically relevant non-major bleeding, intracranial bleeding and any bleeding. The net clinical benefit was estimated as the composite of the two primary outcomes. A sensitivity analysis was performed to better define the incidence of these outcomes in patients with active cancer. The statistical software ProMeta 3 was used to estimate the risk ratio with a random-effect model.
Results
3 RCTs counting a total of 3029 cancer patients (1682 on DOXaI and 1347 on warfarin), 1354 of whom with active cancer (856 on DOXaI and 502 on warfarin), were included in the analysis. Mean age was 75.6 ± 1.2 years, and 32% were female. Mean follow-up period was 2.2 ± 0.6 years. The most common cancer sites were prostate (23%), gastrointestinal tract (22.2%), breast (12.1%) and genitourinary tract (10.6%). The mean CHADS2 score was 2.9 ± 0.6 and the mean HAS-BLED score was 2.6 ± 0.4.
There were no significant differences in the risk of stroke or SE (RR 0.76; 95% CI 0.52-1.10) as well as for all the other secondary efficacy outcomes. DOXaI significantly reduced the incidence of major bleeding in the overall cancer population (RR 0.79; 95% CI 0.63-0.99; p = 0.039); this finding was consistent also in patients with active cancer (RR 0.79; 95% CI 0.59-1.05) although the effect was not statistically significant. DOXaI also significantly reduced intracranial bleeding in overall cancer population (RR 0.12; 95% CI 0.02-0.63; p = 0.013) and any bleeding in active cancer patients (RR 0.87; 95% CI 0.77-0.98; p = 0.026). Furthermore, DOXaI significantly reduced the composite endpoints of major bleeding and stroke or SE in overall cancer population (RR 0.78; 95% CI 0.64-0.94; p = 0.008).
Conclusions
Our metanalysis shows that, in patients with atrial fibrillation and cancer, DOXaI are safer and have a similar efficacy compared with warfarin.

Abstract
BACKGROUND Pleomorphic adenomas are benign tumors of the salivary glands that mainly affect the lower pole of the superficial lobe of the parotid gland. The term "pleomorphic" refers to the epithelial and connective origin of the mass. The clinical presentation is typically that of asymptomatic swelling which increases in volume. Therapy consists in surgical removal of the tumor mass by parotidectomy with nerve preservation. CASE DETAILS This clinical case describes an interesting case of pleomorphic adenoma of the parotid gland in a 62-year-old patient. The patient presented with a long history of an asymptomatic mildly worsening swelling of the left parotid region. The peculiarity of the clinical case is the dimension of the adenoma (9x5x9 cm) and the presence of a thyroid incidentaloma (TI), consisting of a thyroid multinodular goiter composed of nodules, the largest of which measured 8 cm in diameter. This mass dislocated the laryngotracheal axis, compressed the larynx and caused the reduction of the respiratory space, making orotracheal intubation difficult and determining the need to perform a tracheotomy. CONCLUSION Benign pleomorphic adenomas can potentially reach large sizes if untreated. Socio-economic problems may be the reason for late diagnosis.

Abstract
The aim of this retrospective study is to evaluate the results obtained with CO2 TOLMS in patients with Tis, T1, and T2 glottic tumors at our Department from 2004 to 2016 treated with CO2 TOLMS. One hundred eighty-five patients having a median age of 67 years (range 42-88) were included in the present analysis. The tumor stages of the patients included 134 pTis-T1a, 12 pT1b, and 39 pT2 cases. Median duration of follow-up for the whole study cohort was 55 months (range 24-108 months). At 5-year follow-up, local control was 91%, 83%, and 79.4% for T1a, T1b, and T2 respectively. Disease-specific survival was 95.5%, 91.6%, and 92.3%. Overall survival was 73.8%, 91.6%, and 82%, and larynx preservation was 96.2%, 83%, and 84.6%. This study confirms that CO2 TOLMS is a safe and standard therapy for selected T1 and T2 glottic carcinoma, and our review on T2 glottic cancer suggests that CO2 TOLMS represents a reliable option in terms of overall survival, disease-specific survival, and laryngeal preservation. However, patients with anterior commissure involvement and T2 cancer should be evaluated with a preoperative MRI in order to exclude the infiltration of the laryngeal framework and to quantify the neoplastic involvement of para-glottic space.

Abstract
Purpose To evaluate the feasibility and sensitivity of multimodality PET/CT and MRI imaging for non-invasive characterization of brain microglial/macrophage activation occurring during the acute phase in a mouse model of relapsing remitting multiple sclerosis (RR-MS) using [18F]DPA-714, a selective radioligand for the 18-kDa translocator protein (TSPO), superparamagnetic iron oxide particles (SPIO), and ex vivo immunohistochemistry. Methods Experimental autoimmune encephalomyelitis (EAE) was induced in female SJL/J mice by immunization with PLP139–151. Seven symptomatic EAE mice and five controls underwent both PET/CT and MRI studies between 11 and 14 days post-immunization. SPIO was injected i.v. in the same animals immediately after [18F]DPA-714 and MRI acquisition was performed after 24 h. Regional brain volumes were defined according to a mouse brain atlas on co-registered PET and SPIO-MRI images. [18F]DPA-714 standardized uptake value (SUV) ratios (SUVR), with unaffected neocortex as reference, and SPIO fractional volumes (SPIO-Vol) were generated. Both SUVR and SPIO-Vol values were correlated with the clinical score (CS) and among them. Five EAE and four control mice underwent immunohistochemical analysis with the aim of identifying activated microglia/macrophage and TSPO expressions. Results SUVR and SPIO-Vol values were significantly increased in EAE compared with controls in the hippocampus (p < 0.01; p < 0.02, respectively), thalamus (p < 0.02; p < 0.05, respectively), and cerebellum and brainstem (p < 0.02), while only SPIO-Vol was significantly increased in the caudate/putamen (p < 0.05). Both SUVR and SPIO-Vol values were positively significantly correlated with CS and among them in the same regions. TSPO/Iba1 and F4/80/Prussian blue staining immunohistochemistry suggests that increased activated microglia/macrophages underlay TSPO expression and SPIO uptake in symptomatic EAE mice. Conclusions These preliminary results suggest that both activated microglia and infiltrated macrophages are present in vulnerable brain regions during the acute phase of PLP-EAE and contribute to disease severity. Both [18F]DPA-714-PET and SPIO-MRI appear suitable modalities for preclinical study of neuroinflammation in MS mice models.

Abstract
The application of Poincaré plot analysis to characterize inter-beat interval dynamics has been successfully proposed in the scientific literature for the assessment of humans' physiological states and related aberrations. In this study, we proposed novel descriptors to trace the evolution of Poincaré plot shape over the lags. Their reliability in ultra-short cardiovascular series analysis was validated on synthetic inter-beat series generated through a physiologically plausible integral pulse frequency modulation model. Furthermore, we used the proposed approach for the investigation of the direct relationship between autonomic nervous system (ANS) dynamics and hedonic olfactory elicitation, in a group of 30 healthy subjects. Participants with a similar olfactory threshold were selected, and were asked to score 5-s stimuli in terms of arousal and valence levels according to the Russell's circumflex model of affect. Their ANS response was investigated in 35-s windows after the elicitation. Experimental results showed a gender-specific, high discriminant power of the proposed approach, discerning between pleasant and unpleasant odorants with an accuracy of 83.33% and 73.33% for men and for women, respectively. Graphical Abstract Olfaction plays a crucial role in our life and is strictly related to the Autonomic Nervous System (ANS) activity, which can be monitored studying Heart Rate Variability. We used the Lagged Poincare Plot approach to recognize gender-specific ANS response in 35-second windows after the elicitation through pleasant/unpleasant odorants.

Abstract
BACKGROUND Synovial cysts are currently classified as degenerative lesions affecting the joint capsule or adjacent structures. MATERIALS AND METHODS In our study we describe the results obtained in an immunohistochemical study comprising 18 patients with synovial cysts, performed to evaluate the pathophysiological role of some inflammatory cytokines such as: interleukin (IL)-1β, IL-6 and tumour necrosis factor-alpha (TNF-α). RESULTS Results showed an over-expression of TNF-α, IL-1β and IL-6 which appears to be involved in the onset and progression of the disease. At the present time it is not possible to affirm that these molecules play a direct role also due to the absence of further and more specific investigations. The authors therefore hypothesize that inhibition of inflammation may have a significant role in the pathogenesis and regression of synovial cysts. CONCLUSIONS Hence, these inflammatory cytokines may be considered potential therapeutic targets. The development of synthetic inhibitors of these inflammatory factors could lead to a reduction in the intensity of inflammation, thus inhibiting the onset and development of the disease.

Abstract
Alcohol use disorders (AUD) are among the most common and undertreated mental disorders in developed countries. The co-occurrence of psychiatric comorbidity and AUD has already been well documented. Moreover, alexithymia was found associated with heavy drinking and alcohol dependence. A large part of AUD individuals, between 45 and 67%, have been identified as alexithymics. Both psychiatric comorbidity and alexithymia can negatively impact the course of recovery from alcohol. Alcohol consumption has also been shown to significantly influence autonomic responses. Chronic use of alcohol may induce significant changes in heart rate variability, respiratory frequency, electrodermal activity and skin temperature. To date, only a few studies have comprehensively investigated the comorbidity of alexithymia in AUD individuals with dual diagnosis. Thus, the aim and also the novelty of the present investigation were to disclose in individuals with AUD the emotional and cognitive stress responses to selected physiological parameters measured by ProComp5 Infiniti™ encoder in AUD patients suffering alexithymia with or without concomitant dual diagnosis. Quite interestingly, in AUD subjects with concomitant dual diagnosis we found that the alexithymia elevated skin temperature, heart rate variability and decreased respiratory frequency. Alexithymia, if associated with the dual diagnosis condition in AUD individuals, can be considered as a further vulnerability factor to stressing factors, impacting psychosomatic processing and inducing alterations in physiological parameters. In this paper, we discuss the implications of these findings in the early treatment of alexithymic AUD individuals.

Abstract
OBJECTIVE To evaluate whether Sudden Sensorineural Hearing Loss (S-SNHL) may be an early symptom of Multiple Sclerosis (MS). MATERIALS AND METHODS A systematic review was conducted using the following keywords: "Multiple sclerosis, hearing loss, sudden hearing loss, vertigo, tinnitus, magnetic resonance imaging, otoacoustic emission, auditory brainstem responses, white matter lesions, sensorineural hearing loss, symptoms of MS and otolaryngology, nerve disease and MS". Only the articles that included results of at least one auditory test and MRI were considered. We evaluated the prevalence of SNHL in patients with MS, the presence of different forms of SNHL (S-SNHL and Progressive SNHL (P-SNHL)) and their correlation with the stage of MS, the results of electrophysiological tests, and the location (if any) of MS lesions as detected by white matter hyperintensities in the MRI. RESULTS We reviewed a total of 47 articles, which included 29 case reports, 6 prospective studies, 6 cohort studies, 4 case-control studies, and 2 retrospective studies. 25% of patients suffered from SNHL. S-SNHL typically occurred in the early stage of the disease (92% of patients) and was the only presenting symptom in 43% of female subjects. Instead, P-SNHL occurred in the late stage of MS (88% of patients). Auditory Brainstem Responses (ABR) were abnormal in all MS patients with S-SNHL. When S-SNHL appeared during the early stage of the disease, MS lesions were found in the brain in 60% of patients and in the Internal Auditory Canal in 40% of patients. ABR remained abnormal after recovery. CONCLUSIONS S-SNHL can be an early manifestation of MS and should always be considered in the differential diagnosis of this condition, especially in women. The pathophysiology can be explained by the involvement of microglia attacking the central and/or peripheral auditory pathways as indicated by WMHs.

Abstract
Gliomas represent over 50% of tumors occurring in children. Evidence suggests that glioma stem cells (GSCs), maintained by the transforming growth factor-beta (TGF-β1) pathway, and vascularization substantially contribute to tumor aggressiveness. The identification of important angiogenic factors such as vascular endothelial growth factor (VEGF) may represent a crucial step in the therapeutic approach against tumor growth and metastatic diffusion. The aim of this study was to identify the expression of TGF-β1, VEGF and VEGF-receptors in brain gliomas. Specimens of 16 gliomas and 4 controls from children aged 0.2-14 years were used in the study. Immunohistochemical analysis and gene expression study from specimens was performed. Flow cytometry analysis on GSCs was performed to ascertain the expression of VEGF and VEGF-R2 in the tumor stem cell compartment. Newly diagnosed gliomas mainly showed moderate to strong VEGF immunostaining and increased expression of pro-inflammatory molecules in glioma cells. The proportion of TGF-β1 positive endothelial cells was markedly lower in normal brain vessels compared to tumor vessels. These findings demonstrate that the glioma mass is constituted by a phenotypically immature anoxic central area with a proliferating hypoxic layer; the peripheral area is characterized by cell types with a higher degree of differentiation expressing pro-angiogenic factors. Our data have proven that GSCs play a central role in promoting glioma neovascularization. These findings are useful to understand glioma vascularization, have relevant implications in the therapeutic options and may favor new insights into stem cells biology and suggest therapeutic opportunities for the anti-vascular treatment strategy.

Abstract
BACKGROUND: Nearly 200,000 patients are diagnosed with brain metastases in the US annually. Advances in targeted therapies make definitive diagnosis of the primary tumor type important but can be challenging in many patients. The 92-gene assay is a validated gene expression classifier of 50 tumor types for patients with uncertain tissue of origin diagnoses. Results from a clinical series of brain biopsies and potential impact on treatment were evaluated. METHODS: An IRB approved, de-identified database of clinical and molecular information from biopsies (N = 24,486) submitted for testing with the 92-gene assay (CancerTYPE ID, Biotheranostics, Inc.) as part of routine care were reviewed. Descriptive analysis included patient demographics and molecular diagnoses. RESULTS: Analysis included 464 brain biopsies. A molecular diagnosis was provided in 433 (93.3%) tested (< 5% assay failure rate) with 24 different tumor types. Six primary tumor types made up the majority (67.4%) with almost one-third of the molecular predictions being Lung (31.2%), followed by Neuroendocrine (NET) (9.9%), Sarcoma (7.9%), Skin (6.4%), Gastroesophageal (6.2%), and Urinary bladder (5.8%). All of these 6 tumor types, for which activity in the CNS has been documented, have immune checkpoint inhibitors or other targeted therapies approved in selected cases by the US Federal Drug Administration (FDA). CONCLUSIONS: Molecular classification of brain metastases can identify distinct tumor types for which there are FDA approved targeted medications. Improving diagnostic precision with the 92-gene assay helps identify a subset of therapy-responsive metastatic brain tumors, thus improving therapy and possibly providing better outcomes and survival.

Abstract
The dynamical interplay between brain and heart is mediated by several feedback mechanisms including the central autonomic network and baroreflex loop at a peripheral level, also for a short-term regulation. State of the art focused on the characterization of each regulatory pathway through a single stressor elicitation. However, no studies targeted the actual quantification of different mediating routes leading to the generation of heartbeat dynamics, particularly in case of combined exogenous stimuli. In this study, we propose a new approach based on computational modeling to quantify the contribution of multiple concurrent stimuli in modulating cardiovascular dynamics. In this preliminary attempt, the model estimates the high-frequency power of heartbeat dynamics, and derives disentangling coefficients quantifying the effect of multiple elicitations. Model evaluation is performed on healthy rate variability (HRV) series from fourteen healthy subjects undergoing physical (tilt-table) and mental stressors (aritmetics), as well as their combined administration. Results indicate that, at a group-wise level, in base of concurrent physical and mental elicitations, the physical stressor contributes for the 85% of the resulting heartbeat dynamics. These findings are in agreement with the current knowledge on heartbeat regulatory systems, providing valuable perspectives on the quantification of underlying generative mechanisms of HRV.

Abstract
A simple ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for the simultaneous analysis enmetazobactam (also known as AAI101) and cefepime in human plasma. Sample preparation was based on protein precipitation with acetonitrile. Separation was performed on Acquity BEH HILIC column (50 mm × 2.1 mm, 1.7 μm) with a mobile phase containing ammonium formate in water and acetonitrile. The analytes were analyzed with the corresponding isotopically labeled internal standards and were detected in multiple reactions monitoring (MRM) using API 5000 triple-quadrupole mass spectrometer with electrospray (ESI) source operating in positive ion mode. The calibration curves were linear over the selected ranges (r > 0.9970 for both analytes). The intra and inter-assay precision of the Quality Control samples showed CV ≤ 15% and the accuracy was within 85 and 115% in all cases for both compounds. The lower limit of quantification was 0.05 μg/mL for enmetazobactam and 0.5 μg/mL for cefepime.

Abstract
Homeodomain transcription factors play a significant role in adipocyte differentiation. The role of Pbx1 and Prep1, proteins of the TALE family (the three amino acid loop extension), was previously established in adipocyte differentiation of mesenchymal stromal cells and 3T3-L1 cell line. In this study, with the use of RNA interference technology we show that another transcription factor from the same family, Meis1, which is a core protein of mature cardiomyocytes, represses adipogenesis to a greater degree than its paralog Meis2. A number of Meis target genes, markers of adipocytes, are identified. This may indicate the transcriptional mechanism of the effect of Meis1 on the adipocyte differentiation of mouse preadipocytes.

Abstract
The present study aims to obtain a probability model allowing prediction of auditory recovery in patients affected by sudden sensorineural hearing loss treated exclusively with intratympanic steroids. A monocentric retrospective chart review of 381 patients has been performed. A Probit model was used to investigate the correlation between the success of treatment (marked or total recovery according to Furuashi’s criteria) and the delay between onset of disease and beginning of therapy. The age of patients and audiometric curve shapes were included in the analysis. The results show that delay is negatively correlated with variable success. Considering the entire sample, each day of delay decreases the probability of success by 3%. The prediction model shows that for each day that passes from the onset of the disease the probability of success declines in absence of the medical treatment, hence we conclude that early treatment is strongly recommended.

Abstract
OBJECTIVE Otitis media with effusion (OME), defined as the presence of fluid in the ear without signs of an acute infection, usually occurs after acute otitis media and could result in reduced sound transmission with hearing loss. Several risk factors have been suggested to be associated with OME, as well as the relationships between morphology anomalies of cranial bones and ear infections. The aim of this study is to investigate the correlation between OME and cranial deformation in a pediatric population. PATIENTS AND METHODS Eighteen children (13 males and 5 females) with a diagnosis of unilateral OME based on otolaryngologic examination, conductive hearing loss and an asymmetric tympanogram type were enrolled in the study. Patients underwent osteopathic and physical examinations to evaluate the presence of cranial deformations. RESULTS Our study showed a high percentage of skull asymmetry (94%) in the study sample; children were mainly dolichocephalic and with atypical swallowing (72%). Particularly, we observed an occipital flattening, mainly ipsilateral to the ear affected by OME. CONCLUSIONS The results of the present study indicated that a high percentage of children with OME present a skull asymmetry with concomitant dolichocephaly, known to be associated with high arched palate which is also related to a higher incidence of OME.
