Furthermore, it examines the relationship between patients' perception of both voice and swallowing disorders in IPD. Study Design: Prospective clinical study, quality of life (QoL). Methods: One-hundred mentally competent IPD patients with voice and swallowing complaints were asked to answer four QoL questionnaires (Voice Handicap Index, MD Anderson Dysphagia Inventory, Visual Analog Scale [VAS] voice, and Dysphagia Severity Scale [DSS]). Differences in means for the QoL questionnaires and their subscales within Hoehn and Yahr stage groups were calculated using one-way analysis of variance. The relationship between voice-and swallow-related QoL questionnaires was determined with the Spearman correlation coefficient. Results: Scores on both voice and swallow questionnaires suggest an overall decrease in QoL with progression of IPD. A plateau in QoL for VAS voice and the DSS was seen in the early Hoehn and Yahr stages. Finally, scores on voice-related QoL questionnaires were significantly correlated with swallow-related QoL outcomes. Conclusions: Voice-and swallow-related QoL decreases with progression of IPD. A significant association was found between voice-and swallow-related QoL questionnaires. Healthcare professionals can benefit from voice-and swallow-related QoL questionnaires in a multidimensional voice-or swallow-assessment protocol. The patient's perception of his/her voice and swallowing disorders and its impact on QoL in IPD should not be disregarded.

However, limited literature shows the potential association between pharyngeal pooling and aspiration in head and neck cancer (HNC) patients. This study investigates the relationship between postswallow pharyngeal pooling and aspiration in HNC patients with oropharyngeal dysphagia. Furthermore, the effects of tumor stage, tumor location, and cancer treatment on aspiration were examined. Ninety dysphagic HNC patients underwent a standardized fiberoptic endoscopic evaluation of swallowing (FEES) using thin and thick liquid boluses. For each swallow, three visuoperceptual ordinal variables were scored: postswallow vallecular pooling, postswallow pyriform sinus pooling, and aspiration. Logistic regression analyses with correction for the location of pooling, tumor stage, tumor location, and cancer treatment were performed to explore the association between pooling and aspiration. No significant association was found between postswallow vallecular pooling and aspiration for thin liquid. However, severe versus mild-to-moderate postswallow vallecular pooling of thick liquid was significantly associated to aspiration. Similar results were seen after correction for the presence of pyriform sinus pooling, tumor stage, tumor location, or type of cancer treatment. This study showed a significant association between severe postswallow pyriform sinus pooling of thick liquid and aspiration, independent of the presence of vallecular pooling, tumor stage, tumor location, or cancer treatment. Concluding, location (valleculae versus pyriform sinuses), liquid bolus consistency (thin versus thick liquid), and amount of postswallow pharyngeal pooling (no pooling, mild/moderate pooling, severe pooling) have an influence on the probability of aspiration in dysphagic HNC patients, and they should be carefully considered during FEES, even in the absence of aspiration during the examination.

However, the safety of MB is being questioned since serious adverse events (AEs) such as hemodynamic instability, hemolysis, and serotonin syndrome were reported. The aim of this study is a systematic analysis of the literature to obtain an evidence-based overview of AEs due to oral administration of MB and to determine its safety as a food dye during swallowing assessment. A systematic literature search was carried out in PubMed, Embase, and Cochrane Library. Two reviewers independently selected articles describing oral administration of MB as a main diagnostic/therapeutic intervention, dosage, and AEs. Expert opinions, conference papers, sample size < 10, and animal studies were excluded. Level of evidence of the included studies was determined. A total of 2264 unduplicated articles were obtained. Seventeen studies met the inclusion criteria with 100% agreement between the two reviewers. Among these, twelve studies were randomized controlled trials. In a pooled population of 1902 patients receiving oral MB, three serious AEs were reported related to MB. Non-serious AEs showed a dose-related trend and were usually mild and self-limiting. A meta-analysis could not be performed as studies were methodologically too heterogeneous. Serious AEs due to oral administration of MB are rare (n = 3, 0.16%). MB-related non-serious AEs are mild, self-limiting, and show a dose-related trend. These findings indicate that it is safe to use small amounts of MB as a food dye during swallowing examinations.

As both subdisciplines have a strong tradition and clinical experience in endoscopic assessment of the upper aerodigestive tract, the implementation of fiberoptic endoscopic evaluation of swallowing (FEES) was an almost self-evident evolution. This review aims to provide an update on FEES and the role of phoniatricians and otorhinolaryngologists using FEES in Europe. Methods A narrative review of the literature was performed by experts in the field of FEES both in the clinical context and in the field of scientific research. Results FEES is the first-choice OD assessment technique for both phoniatricians and otorhinolaryngologists. FEES is becoming increasingly popular because of its usefulness, safety, low costs, wide applicability, and feasibility in different clinical settings. FEES can be performed by health professionals of varying disciplines, once adequate knowledge and skills are acquired. FEES aims to determine OD nature and severity and can provide diagnostic information regarding the underlying etiology. The direct effect of therapeutic interventions can be evaluated using FEES, contributing to design the OD management plan. Standardization of FEES protocols and metrics is still lacking. Technological innovation regarding image resolution, frame rate frequency, endoscopic light source specifications, and endoscopic rotation range has contributed to an increased diagnostic accuracy. Conclusion The rising number of phoniatricians and otorhinolaryngologists performing FEES contributes to the early detection and treatment of OD in an aging European population. Nevertheless, a multidisciplinary approach together with other disciplines is crucial for the success of OD management.

The alternation between students for the test is performed with or without auscultation eliminates the ''test effect''. No information was communicated between students among themselves and with the doctor. The results are presented in the form of ROC curves established according to the use or not of auscultation during the test food. Cervical auscultation does not change the area under the curve. The trend is even reversed with a decrease in performance with the severity of silent aspiration. Thus, auscultation did not improve the performance of the test food in terms of predicting aspiration in the learning phase of swallowing tests by two students in speech therapy. The same study is now complete with experienced pathologists.

Methods: Following the PRISMA guidelines, a systematic search was performed using the electronic databases PubMed, Embase, and Google Scholar. Results: Of the 902 analyzed unique studies, 74 were included in a quantitative synthesis and 24 in a meta-analysis. Human papillomavirus (HPV) was reported as a molecular parameter in 38 studies, followed by p16 and TP53 (23 and 14 studies, respectively). The variety of other molecular parameters concerned sporadic findings in small numbers of NSND. Conclusions: HNSCC in NSND is more often related to HPV and p16 overexpression compared to tumors of smokers-drinkers. In a third of virusnegative tumors, TP53 mutations were detected with a mutational profile associated with aging and ultraviolet light exposure rather than to tobacco consumption. K E Y W O R D S head and neck cancer, human papillomavirus, nonsmokers, p16, TP53 1 | BACKGROUND Head and neck squamous cell carcinoma (HNSCC) usually results from excessive tobacco and alcohol consumption. 1 A third risk factor in head and neck carcinogenesis is high-risk human papillomavirus (HPV), especially in the oropharynx. 2,3 Patients with HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) usually have a Meetings at which the manuscript was presented: 7th World Congress of the

This study aimed to assess the effects of surface electrical stimulation plus voice therapy on voice in dysphonic patients with idiopathic Parkinson's disease. Method. Patients were assigned to 3 treatment groups (n = 28 per group) and received daily treatment for 3 weeks on 5 days a week. All three groups received voice therapy (usual care). In addition, two groups received surface electrical stimulation, either motor-level or sensory-level stimulation. A standardised measurement protocol to evaluate therapeutic effects included the Voice Handicap Index and videolaryngostroboscopy. Results. Voice Handicap Index and videolaryngostroboscopic assessment showed statistically significant differences between baseline and post-treatment across all groups, without any post-treatment differences between the three groups. Conclusion. Intensive voice therapy (usual care) improved idiopathic Parkinson's disease patients' self-assessment of voice impairment and the videolaryngostroboscopic outcome score. However, surface electrical stimulation used as an add-on to usual care did not improve idiopathic Parkinson's disease patients' self-assessment of voice impairment or the videolaryngostroboscopic outcome scores any further.

This study (1) described the training process of the observers for DIGEST in fiberoptic endoscopic evaluation of swallowing (FEES), (2) determined observer agreement on the DIGEST in FEES, (3) explored the effect of bolus consistency on observer agreement, and 4) explored criterion validity of the DIGEST in FEES. Methods Twenty-seven dysphagic HNC patients were enrolled. Two observers completed a training program for DIGEST in FEES. Observer agreement on the Penetration-Aspiration Scale (PAS), percentage of pharyngeal residue (PPR), and DIGEST grades was determined using linearly weighted Cohen's kappa coefficient (κ). Results Due to insufficient observer agreement after the first measurement attempt, additional training was organized using an elaborated manual with descriptions of the visuoperceptual variables, thereby improving observer agreement. Intraobserver agreement was almost perfect on the PAS (κ = 0.86-0.88) and PPR (κ = 0.84-0.86). Interobserver agreement was substantial on the PAS (κ = 0.78), almost perfect on the PPR (κ = 0.82), substantial on the safety grade (κ = 0.64), almost perfect on the efficiency grade (κ = 0.85), and substantial on the summary grade (κ = 0.71). Bolus consistency had an effect on observer agreement. A significant correlation was found between DIGEST efficiency grade and EAT-10. Conclusion The DIGEST showed to be a reproducible measurement for FEES in terms of observer agreement. However, agreement between novice observers on the DIGEST was only reached after specific observer-tailored training. Observer agreement should be analyzed by taking bolus consistency into account during training, as this might affect the interpretation of the outcome. A manual with well-defined descriptions can optimize the reproducibility of DIGEST measurements.

A... more Oropharyngeal dysphagia (OD) is a high impact morbidity in head-and-neck cancer (HNC) patients. A wide variety of instruments are developed to screen for affective symptoms and OD. The current paper aims to systematically review and appraise the literature to obtain insight into the prevalence, strength, and causal direction of the relationship between affective symptoms and OD in HNC patients. This review was conducted in accordance with the PRISMA statement. A systematic search of the literature was performed using PubMed, PsycINFO, Cochrane, and Embase. All available publications reporting on the relationship between affective conditions and swallowing function in HNC patients were included. Conference papers, tutorials, reviews, and studies with less than 5 patients were excluded. Fifteen studies met the inclusion criteria. The level of evidence and methodological quality were assessed using the ABC-rating scale and QualSyst critical appraisal tool. Eleven studies reported a positive relationship between affective symptoms and OD. The findings of this paper highlight the importance of affective symptom screening in dysphagic HNC patients as clinically relevant affective symptoms and OD seems to be prevalent and coincident in this population. Considering the impact of affective symptoms and OD on patients' daily life, early detection and an integrated interdisciplinary approach are recommended. However, due to the heterogeneity of study designs, outcomes, and outcome measures, the generalization of study results is limited.

Methods A SWAL-QOL questionnaire was completed by 75 DM1 patients and 25 healthy control subjects. The severity of the disease was evaluated using the muscular impairment rating scale (MIRS). Twenty-eight DM1 patients underwent a videofluroscopic swallowing examination (VFS). Spearman's correlation coefficient was used to measure the direction and strength of associations. Results The SWAL-QOL median scores were significantly lower for the DM1 group than for the healthy control group. The scores for the majority of the SWAL-QOL domains were lower in patients with proximal muscular weakness (MIRS 4 and 5). Postswallow vallecular pooling and piecemeal deglutition were the most impaired VFS outcome variables. Conclusion Our results suggest that a multidimensional swallowing assessment is recommended for DM1 patients as SWAL-QOL and VFS measure different aspects of the swallowing function, thus providing complementary information.

This study evaluates the predictive and prognostic value of weight loss and changes in body composition prior to and during ICI therapy in R/M HNSCC. Methods: This retrospective multicenter cohort study enrolled ninety-eight patients. Patient, tumor and treatment characteristics were retrieved from health records, including neutrophil and platelet-lymphocyte-ratio (NLR and PLR). Cachexia was defined according to the international consensus (Fearon et al. 2011). Skeletal muscle (SM), subcutaneous adipose tissue (SAT), and visceral adipose tissue (VAT) were evaluated on baseline and follow-up computed tomography scans at the third lumbar vertebrae level. Univariable and multivariable regression analysis were performed for six months progression free survival (PFS6m) and overall survival (OS). Results: Thirt...

Rapid evaporative ionization mass spectrometry (REIMS) of electrosurgical vapors has been reported for real-time classification of normal and tumor tissues for numerous surgical applications. However, the infiltrative pattern of invasion of oral squamous cell carcinomas (OSCC) challenges the ability of REIMS to detect low amounts of tumor cells. We evaluate REIMS sensitivity to determine the minimal amount of detected tumors cells during oral cavity cancer surgery. A total of 11 OSCC patients were included in this study. The tissue classification based on 185 REIMS ex vivo metabolic profiles from five patients was compared to histopathology classification using multivariate analysis and leave-one-patient-out cross-validation. Vapors were analyzed in vivo by REIMS during four glossectomies. Complementary desorption electrospray ionization–mass spectrometry imaging (DESI-MSI) was employed to map tissue heterogeneity on six oral cavity sections to support REIMS findings. REIMS sensitivity was assessed with a new cell-based assay consisting of mixtures of cell lines (tumor, myoblasts, keratinocytes). Our results depict REIMS classified tumor and soft tissues with 96.8% accuracy. In vivo REIMS generated intense mass spectrometric signals. REIMS detected 10% of tumor cells mixed with 90% myoblasts with 83% sensitivity and 82% specificity. DESI-MSI underlined distinct metabolic profiles of nerve features and a metabolic shift phosphatidylethanolamine PE(O-16:1/18:2))/cholesterol sulfate common to both mucosal maturation and OSCC differentiation. In conclusion, the assessment of tissue heterogeneity with DESI-MSI and REIMS sensitivity with cell mixtures characterized sensitive metabolic profiles toward in vivo tissue recognition during oral cavity cancer surgeries.

The effect of tooth loss on body weight loss and tube feeding (TF) dependency during CRT/BRT is unknown. This study aimed to evaluate the effect of incomplete dentition, tooth extractions prior to CRT/BRT, and the subsequent loss of functional units on (1) weight loss during CRT/BRT and (2) the need for TF during CRT/BRT for OPSCC. Methods OPSCC patients treated with CRT/BRT between 2013 and 2016 were included in this retrospective cohort study. Dental status was determined during the dental assessment at first visit and after tooth extractions prior to the start of CRT/BRT. Weight loss during CRT/BRT was scored dichotomously, comparing weight loss > 5% to stable or increased weight. Potential factors associated with weight loss were identified, including p...

The purpose of this study is two-fold: to identify the risk of malnutrition in patients with oropharyngeal dysphagia (OD) secondary to HNC, and to determine the relationship between the risk of malnutrition versus tumor characteristics, treatment modality, time interval (between the end of oncological treatment and swallowing assessment date), level of oral intake, body mass index (BMI), aspiration, pharyngeal pooling, and OD-related quality of life (QoL). METHODS The Short Nutritional Assessment Questionnaire (SNAQ) was used to screen patients for the risk of malnutrition. Patients underwent a standardized swallowing examination protocol including an endoscopic evaluation of swallowing. RESULTS Seventy-five dysphagic HNC patients were included. Forty-eight percent of the patients presented a high risk of malnutrition using SNAQ. The majority of the patients (81.3%) was on a total oral diet. Moreover, BMI did not appear to be a reliable measure to screen for malnutrition as a normal BMI was often associated with an increased risk of malnutrition on the SNAQ. In contrast, patients who were underweight or overweight did not show an association with a high risk of malnutrition. With the exception of BMI, no other patient and tumor characteristics were found to be associated with the risk of malnutrition. CONCLUSIONS This study emphasizes the importance of early nutritional screening in dysphagic HNC patients, as almost half of these patients presented a high risk of malnutrition. Malnutrition screening using SNAQ can identify HNC patients with OD who are at risk of malnutrition and subsequently need to be referred to a dietician for additional nutritional assessment, diagnosis of malnutrition, and nutritional support, even when their BMI is within normal range.

International guidelines recommend gastrostomy insertion when the expected use of TF exceeds four weeks. In this study we aimed to update and externally validate a prediction model to identify patients in need for TF for at least four weeks, meeting the international criteria for prophylactic gastrostomy insertion. Methods: This retrospective multicenter cohort study was performed in four tertiary referral head and neck cancer centers in the Netherlands. The prediction model was developed using data from the University Medical Center Utrecht and the Netherlands Cancer Institute. The model was externally validated in patients from the Maastricht University Medical Center and Radboud University Medical Center. Th...

Patient: We present a case of a 68-year-old man with complaints of unilateral hearing loss and an ipsilateral facial nerve paresis. Radiological and histopathological examination revealed a cT4bN0M0 mucosal melanoma of the middle ear. Interventions: The patient underwent a subtotal petrosectomy and postoperative radiotherapy. Main Outcome Measure: Computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography/computed tomography with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG-PET-CT), and histopathological examination. Results: After subtotal petrosectomy, histopathological examination of the resection specimen showed only fibrosis and a histiocytic and clonal T-cell infiltration, but no residual melanoma at the primary tumor site, consistent with spontaneous tumor regression. Follow-up MRI scanning 6 and 12 months after radiotherapy showed no signs of tumor recurrence. Conclusions: This case describes the concept of spontaneous regression of a mucosal melanoma of the middle ear. Spontaneous tumor regression at this location has not been described before.
