Introduction: This study proposes a revised version of the Reflux Symptom Index (R-RSI), a seventeen-item questionnaire that was revised to increase the suspicion of laryngopharyngeal reflux disease (LPRD)., Methods: Internal validation involved 213 participants, comprising 160 subjects without a previous LPRD diagnosis and 53 subjects with a self-reported previous diagnosis of LPRD with or without gastroesophageal reflux disease (GERD). Test-retest reliability and internal consistency were calculated. For the external validation, 56 patients (independent from the previous cohort) were enrolled to explore the R-RSI screening properties and determine a cutoff using 24-h MII-pH as the gold standard., Results: R-RSI test-retest reliability was high, both for the total score (ICC: 0.970) and for each item (ranging from 0.876 to 0.980). Cronbach's alpha was 0.910, indicating excellent internal consistency of the questionnaire. Participants with a previous self-reported diagnosis scored significantly higher (mean 24.94 ± 7.4; median 26, IQR 20-29) than those without a previous diagnosis (mean 4.66 ± 5.3; median 4, IQR 1-6) (p value <0.0001). Participants with both previous LPRD and GERD diagnoses had higher scores (27.20 ± 7.8) compared to those with only LPRD (21.77 ± 5.5) (p value = 0.003). Using 24-h MII-pH diagnosis as a gold standard, the optimal R-RSI cutoff point was determined to be 18, with a sensitivity of 84.5% and a specificity of 81.8%, positive predictive value of 95%, and negative predictive value of 60%., Conclusions: Our results suggest that the R-RSI may be useful to suspect LPRD, with or without GERD. The R-RSI is a self-administered patient-reported outcome questionnaire that demonstrates excellent reliability and high screening properties. Employing a cutoff of ≥18 in the R-RSI can assist in diagnosing and monitoring LPRD., (© 2024 S. Karger AG, Basel.)

Objective: The aim of this study was to adapt and validate the Italian version of the singing Voice Handicap Index-10 (SVHI-10-IT)., Methods: 99 Italian singers were enrolled in the study. All subjects underwent videolaryngostroboscopic examination and were asked to fill out the self-reported 10-item SVHI-10-IT. Laryngostroboscopic examination was pathological in 56 subjects (study group) (56.6%), while it was normal in the remaining 43 singers (control group) (43.4%). Dimensionality, test retest and internal validity for SVHI-10-IT were performed. Videolaryngostroboscopy was used as gold-standard for external validity., Results: The items of SVHI-10-IT were uni-dimensional and Cronbach's α was 0.853 (95% CI = 0.805-0.892). High and comparable area under curve (AUC:0.93 95% CI = 0.88-0.98) values indicate a good ability of the scale to distinguish between the study and control groups. Based on balanced sensitivity (Se = 83.9%) and specificity (Sp = 86.0%), the optimal cut-off score for a singer's perceived voice handicap was 12., Conclusions: The SVHI-10-IT is a reliable and valid instrument to evaluate the self-reported singing voice handicap among singers. It can also be used as a quick screening tool since a score higher than 12 is indicative of a problematic voice as perceived by singers., (Copyright © 2023 Società Italiana di Otorinolaringoiatria e Chirurgia Cervico-Facciale, Rome, Italy.)

Introduction: The present study aimed to develop a new tool for the evaluation of singers with self-reported symptoms suggestive of laryngopharyngeal reflux (LPR) (the SVHI-12-LPR), by correlating RSI with SVHI in a population sample of 163 subjects (both professional and amateur singers), evaluated also by videolaryngostroboscopy. This study was a cross-sectional, double-observational study., Methods: RSI and SVHI were administered to 159 singers (amateurs, singing students, and professional singers). All subjects underwent videolaryngostroboscopy to objectively identify four subgroups: normal subjects (41.5%), subjects with organic lesions occupying the glottic space (17.6%), subjects with functional dysphonia (18.2%), and subjects presenting solely signs suggestive of LPR (22.6%). Using the validated RSI threshold, 33.9% of participants presented an RSI total score >13, suggestive of LPR., Results: Subjects with a suspected diagnosis of LPR at videolaryngostroboscopy presented a mean RSI significantly higher than other subgroups (p < 0.001). Moreover, the SVHI-36 score did not statistically differ between pathological subgroups. A significant positive relationship was observed between RSI and SVHI total score (Spearman's rank correlation coefficient [ρ] = 0.474, p < 0.001). 12 SVHI items (items 1, 2, 4, 5, 6, 7, 12, 20, 24, 25, 26, 30) showed a significant association with RSI pathology classification. Statistical analysis demonstrated for the 12 selected items (SVHI-12-LPR) acceptable specificity (0.691) and sensibility (0.833) for the suspected diagnosis of LPR with a cut-off of 15., Conclusions: From the SVHI-36, 12 items were extracted that correlated with the specific impact that LPR has on the singer's voice (SVHI-12-LPR), as evaluated by RSI and videolaryngostroboscopy. Such questionnaire represents a new tool that could be applied to singers with symptoms suggestive of LPR to select which patients would benefit from a further phoniatric and videolaryngostroboscopic evaluation., (© 2023 S.

Objective: Dysphagia is a common symptom in Parkinson's disease (PD) and it represents a negative prognostic factor because of its complications. This study is to evaluate pharyngeal dysphagia for boluses of various consistencies with Fiberoptic Endoscopic Evaluation of Swallowing (FEES) and Pharyngeal High-Resolution Manometry (PHRM) in a group of PD patients, making a comparison between the information provided by the two exams., Methods: Group of 20 patients affected by PD was selected and initially subjected to a qualitative evaluation of the swallowing performing FEES. Subsequently, they were evaluated by PHRM to identify quantitative measures associated with pressures expressed by pharyngeal organs during swallowing. Values obtained in the study group were compared with those recorded in a group of 20 healthy subjects., Results: Study showed that Pmax (the maximum pressure elicited by the single pharyngeal muscle structures involved in swallowing) was significantly lower than the control group (p<0.05) for all the boluses and consistency tested, in particular for the Tongue base and the Cricopharyngeal muscle. Pmean pre-swallowing pressure (represents the mean value of a contraction in which basal and maximal pressure where normally calculated) was significantly higher compared to normal subjects for the Tongue base and the Cricopharyngeal muscle (p<0.05). Mean intra-swallowing pressure was higher for the Velopharynx and the Cricopharyngeal muscle, but lower for the tongue base. Pmax and Pmean at PHRM were altered independently to the degree of dysphagia detected at FEES, and they did not correlate either with the location of the residue or with the type of bolus. Images displayed at the FEES, found the corresponding biomechanical explanations in the PHRM, which also allowed us to quantify the extent of the dysfunction, through the calculation of the pressures generated in the various structures studied., Conclusion: PHRM is particularly useful in the early detection of dysphagia, when FEES may still show no evidence of abnormal swallowing., Competing Interests: Declaration of Competing Intrest All authors declare that they have no conflicts of interest, (Copyright © 2022.

Objectives: To confirm the data reported in our previous studies on the analysis of the variability of the electroglottographic signal in the pathological voice; to evaluate possible differences in variability between organic and functional pathologies; to identify any distinctive/typical EGG patterns for these pathologies., Methods: One hundred twenty-five subjects were enrolled (36 euphonic and 89 pathological: 24 functional dysphonia, 21 bilateral vocal nodules, 23 unilateral polyps and 21 unilateral cysts). All subjects were studied with videolaryngostroboscopy, spectrographic analysis of voice and electroglottography (EGG). The EGG signal variability was then investigated using amplitude-speed combined analysis, by means of a proprietary software algorithm. Amplitude and Speed variation were expressed as a new parameter, the Variability Index (VI), calculated both for the whole EGG signal recorded (VI-tot) and in each phase of the glottic cycle (VI-Q, absolute value; VI-Q%, percentage value)., Results: In the comparison of VI values between pathological and normal groups, VI-tot and VI-Q2% (which corresponds to the final phase of vocal fold contact) were significantly greater in pathological subjects (P= 0.002). The comparison of VI values among subgroups of the various pathologies showed a difference for VI-tot (P< 0.0001) and VI-Q2% (P= 0.001); this difference was more marked in the cysts than in the functional dysphonia. The cut-off values of VI-tot and VI-Q2% were 0.191 and 18.17%, respectively (sensitivity and specificity 65.2% and 66.7% for VI-tot and 84.3% and 77.8% for VI-Q2%)., Conclusions: The variability of the EGG signal investigated through the combined analysis of the amplitude and the speed of vibration using a proprietary algorithm software has proved useful not only to distinguish the normal voice from the pathological voice, but also to characterize which phases are more altered in the various voice pathologies studied, both functional and organic. Furthermore, the analysis of the VI parameter allowed to propose cut-off values characterized by a good sensitivity and specificity to discriminate dysphonia from the euphonic voice. Larger groups of patients will be needed to confirm these results., Competing Interests: Conflicts of interest None., (Copyright © 2020 The Voice Foundation. Published by Elsevier Inc.

Background: The effect of psychopathology on swallowing ability tends to be an overlooked issue in the assessment of dysphagic patients, possibly overshadowed by the given prominence to organic pathologies and the difficulties on the management of these patients. In addition, it should also be kept in mind that a great number of psychotropic drugs can affect swallowing adding problematic clinical issues in this area. Despite this, assessment of dysphagia should be considered as an extremely important issue, due to its impact on basic symptomatology, course of illness and quality of life., Objective: This review aims to be an overview of relevant data on psychopathology associated with dysphagia and impairment of swallowing function., Materials and Methods: An extensive bibliographic search was carried out in different medical databases (PubMed and Psycharticles) to comprehensively identify the most relevant publications available on dysphagia in eating disorders published until December 2020, according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) method. Research articles, either theoretical or empirical-based, published in peer-reviewed journals and in English language, were included. Case reports were also considered in the analysis when it was appropriate for completeness purposes. Titles and abstracts were reviewed according to the eligibility criteria., Results: In total, 260 published studies were identified and 40 were finally selected after removal of duplicates and relevance. Primarily we investigated the correlation between dysphagia and eating disorders, analysing the complex relationship between the two conditions. Then we provided an overview of the assessment of dysphagic symptoms in other psychiatric syndromes., Limits: No exclusion criteria or statistical methods were applied nor was an assessment of study-level or outcome-level bias applicable for our purpose. The topic is vast and research bias could not be excluded; moreover, data available are heterogeneous and lacking systematic approach., Conclusions: With this review, the authors want to provide an overview of the most considerable and clinically useful information about the topic, focusing on some key points to disentangle psychiatric components from the complexity of patient with dysphagia. It should be a relevant concern for all clinicians and should be always thoroughly assessed, considered its frequency in clinical practice and its implications in every kind of patients' morbidity, mortality and quality of life. Special attention should be paid to mentally ill patients, who might display complex and multiple comorbidities, as well as consequences of abnormal eating behaviours, occasionally exacerbated by psychotropic medications. More systematic studies are needed, while it seems clear that a multidisciplinary approach is pivotal in the assessment and management of dysphagic patients., Level of Evidence: Level I (evidence obtained from at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies)., (© 2021.

Objective: To correlate, RSI with SVHI, in a group of singing students, by means of a specific anamnestic questionnaire which analyzes the physical, social, emotional, and economic impacts of voice problems on their lives. This study is a cross-sectional single-center observational study., Methods: Forty-two modern singing students (26F/16M; average age: 24.9 ± 5.7; range: 16-46 years old) were recruited. A self-assessment of the singing-voice (SVHI) and of reflux symptom (RSI) was performed., Results: Using the validated RSI threshold, 31% of participants were classified as RSI greater than 13 as an indication of suspected LPR. Classifying the SVHI score as proposed in the recent literature (cutoff of 20.35) our sample was a voice disorders prevalence of 71.4%. There was no significant positive or negative relationship between RSI and SVHI total score (rho = 0.238, P = 0.13). Instead, by considering the relationship between the individual items of the two questionnaires, it is highlighted that the item 1 of SVHI was significantly correlated with most of the RSI items (P = 0.0001-0.006). In the same vein, the item 5 of SVHI was correlated to hoarseness and coughing (P = 0.005-0.006). The item 20 of SVHI was significantly correlated with hoarseness, excess mucus in the throat or postnasal drip and with the pharyngeal Globus sensation (P = 0.001-0.005). By aggregating the SVHI item response as a positive response (2-4) versus a negative response (0 or 1) between "RSI pathology classification," a significant association was observed for SVHI item 1 (P < 0.021), item 5 (P < 0.006), item 20 (P < 0.042), item 24 (P < 0.044) item 25 (P < 0.047). These associations were confirmed by univariate binary logistic. Multivariate binary logistic regression confirms that SVHI Item 1, Item 5 were more associated with RSI positive. Based on results, we propose a questionnaire that combines the most relevant SVHI items correlated to LPRD (SVHI-10-LPRD questionnaire). Cronbach's alpha coefficient for the 10 items selected was 0.87; item-total correlation coefficients for each item were in the range of 0.461 to 0.670., Conclusions: This pilot study shows that, in case of significant RSI for LPR, it is possible to observe a significant association with some symptoms described in SVHI. These results underline that the association of the RSI and SVHI questionnaires administered to singers and singing students, can represent a simple screening to reveal possible alterations of the singing voice correlate to LPR. Moreover, we propose a Singing Voice Handicap Index correlated to LPR (SVHI-10-LPRD). It will be necessary to increase the sample of subjects in the study to confirm these preliminary data., (Copyright © 2020 The Voice Foundation. Published by Elsevier Inc. All rights reserved.)

Objective: To evaluate retrospectively the incidence of complications during fiberoptic endoscopic evaluation of swallowing (FEES) in 5,680 examinations., Patients and Methods: 5,680 patients were evaluated at the Department of Otorhinolaryngology, Audiology and Phoniatrics of Pisa University Hospital between January 2014 and December 2018, involving both inpatients and outpatients. Most common comorbidities included neurological pathologies such as stroke (11.8%), neurodegenerative diseases (28.9%) and a history of previous head and neck surgery (24.6%). The evaluation was conducted by clinicians with experience in swallowing for a minimum of 10 years with the assistance of one or more speech-language pathologists., Results: In all patients studied the endoscope insertion was tolerated, and it was possible to visualize the pharyngolaryngeal structures. Three subjects refused to undergo the procedure after being informed regarding the protocol and were therefore not included in this study. Most patients reported discomfort (70.1%) and gagging (20.8%). In a minority of patients complications were recorded, such as anterior epistaxis (0.1%), posterior epistaxis (0.02%), vasovagal crises (0.08%) and laryngospasm (0.04%). Especially laryngospasm was recorded in patients affected by amyotrophic lateral sclerosis. Multivariate binary logistic regression showed that discomfort (OR 9.944; CI 7.643-12.937), chronic gastrointestinal diseases (OR 2.003; CI 1.518-2.644), neurodegenerative diseases (OR 1.550; CI 1.302-1.846) and brain tumors (OR 1.577; CI 1.179-2.111) were risk factors associated with minor complications., Conclusions: FEES proved to be easy to perform, well tolerated by the patients and cost-effective. It can be performed at the patient's bedside, and it is characterized by a low rate of complications. As a matter of fact, normally only discomfort, gagging and/or vomiting are reported. Complications occurred only rarely, such as anterior or posterior epistaxis episodes or vasovagal crises, but these are still easily managed. Exceptionally, more severe complications are reported: adverse drug reactions to substances such as blue dye (methylene blue) and local anesthetics (not used in our protocol), and laryngospasm., (© 2022 S.
