RESUMO
INTRODUCTION: To update the European guidelines for the assessment of voice quality (VQ) in clinical practice. METHODS: Nineteen laryngologists-phoniatricians of the European Laryngological Society (ELS) and the Union of the European Phoniatricians (UEP) participated to a modified Delphi process to propose statements about subjective and objective VQ assessments. Two anonymized voting rounds determined a consensus statement to be acceptable when 80% of experts agreed with a rating of at least 3/4. The statements with ≥ 3/4 score by 60-80% of experts were improved and resubmitted to voting until they were validated or rejected. RESULTS: Of the 90 initial statements, 51 were validated after two voting rounds. A multidimensional set of minimal VQ evaluations was proposed and included: baseline VQ anamnesis (e.g., allergy, medical and surgical history, medication, addiction, singing practice, job, and posture), videolaryngostroboscopy (mucosal wave symmetry, amplitude, morphology, and movements), patient-reported VQ assessment (30- or 10-voice handicap index), perception (Grade, Roughness, Breathiness, Asthenia, and Strain), aerodynamics (maximum phonation time), acoustics (Mean F0, Jitter, Shimmer, and noise-to-harmonic ratio), and clinical instruments associated with voice comorbidities (reflux symptom score, reflux sign assessment, eating-assessment tool-10, and dysphagia handicap index). For perception, aerodynamics and acoustics, experts provided guidelines for the methods of measurement. Some additional VQ evaluations are proposed for voice professionals or patients with some laryngeal diseases. CONCLUSION: The ELS-UEP consensus for VQ assessment provides clinical statements for the baseline and pre- to post-treatment evaluations of VQ and to improve collaborative research by adopting common and validated VQ evaluation approach.

PURPOSE: To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe. METHODS: Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion. RESULTS: Twenty-four sections on HNC-specific OD topics. CONCLUSION: This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Laryngeal framework surgery is an umbrella term for all phonosurgical procedures by which the cartilaginous structure of the larynx and thereby the position and tension of the vocal folds are changed. The aim is to improve the voice. By far the best known and most frequently performed operation is thyroplasty type 1 according to Isshiki, also known as medialization thyroplasty, which is indicated for treatment of glottic insufficiency. Although the first medialization thyroplasty was successfully performed by Payr in Germany in 1915, more than 100 years later, it is still not widely used in Germany.

BACKGROUND: Since many years, office-based flexible transnasal laryngoscopy is a common routine procedure. The development of new technical equipment such as high-definition cameras and flexible tip-chip endoscopes nowadays allows for much more precise examination than a few years ago. In contrast to rigid laryngoscopy, it is possible to move the tip of the endoscope close to the vocal folds and to other structures of interest. Nevertheless, without professional handling of the equipment, one cannot benefit from the potential of the newest technology. METHOD: Two easily performed and very helpful maneuvers in flexible endoscopy are described. The "dipping maneuver" enables a maximum magnification of the mucosal surfaces of the endolarynx as well as the examination of the subglottal region and the trachea by positioning the tip of the endoscope very close to the vocal folds or even in the upper trachea during long transnasal inspiration. During the "rotation laryngoscopy", the tip of the endoscope is positioned in the posterior interarytenoid region by rotating the flexible endoscope by 180° and advancing it close to the glottis. This allows a close-up examination of the anterior commissure, the inferior aspect of the vocal folds and the inside of the Morgagni's ventricle. Before performing transnasal flexible endoscopy, we routinely apply topical anesthesia sprayed intranasally. CONCLUSION: The described techniques of flexible endoscopy are easily performed and allow a maximum magnification of the mucosal surfaces and otherwise not visible regions of the endolarynx.

With photoangiolytic lasers like KTP (Potassium-Titanyl-Phosphate, 532ânm) lasers or the new "blue" laser (445ânm), even the smallest vessels and capillaries within the vocal fold can be treated without destroying the covering epithelium. This enables effective treatment of benign and malignant sub- and intraepithelial lesions of the vocal folds such as papilloma, edema, polyps, leukoplakia, dysplasia and capillary vessels while preserving the vibratory properties of the different layers of the lamina propria. Because photoangiolytic laser light can be routed through tiny glass fibers, office-based surgery with channelled flexible endoscopes are feasible as well as phonomicrosurgical operations under general anesthesia. Furthermore, the so called "blue" laser can cut tissues and thus broadens the technical armamentarium of the phonosurgeon.

This study investigated the cross-national adaptation and implementation of Papilio, a German social-emotional learning programme, in Finnish early childhood education and care (ECEC) centres. Papilio is a developmentally focused, scientifically based intervention programme focused on preventing behavioural problems and fostering social-emotional competence in children aged 3-7. The aim of this study was to investigate and evaluate the cross-national adaptation and cross-cultural adaptation and implementation of Papilio in the Finnish ECEC context. Results from qualitative interviews with one Finnish Papilio trainer, 11 early childhood education (ECE) teachers, two ECE special education teachers and two nursery nurses are supplemented with teachers' and nursery nurses' (N = 75) questionnaire data. Qualitative thematic analysis revealed that cultural adaptations were necessary on four levels: accommodation of materials, adaptation of the contents of the materials, structure and delivery. The materials and training contents were culturally adapted, whereas the delivery of the intervention was adapted according to Finnish ECEC practices. The structural adaptation included discarding timeout, due to opposition by some educators. The educators were committed to implementing the programme as instructed and resolving the practical difficulties they encountered. Their motivation to implement Papilio increased as they observed improvements in the children's social-emotional competence during intervention.

Current reviews revealed that there is a lack of effective programs and valuable effectiveness studies related to prevention of aggressive behavior and fostering of social competence in early adolescents participating in organized team sports (e.g., ball sports, such as soccer). Using a randomized controlled design, the present pilot study presents first results regarding the effectiveness of the preventive intervention program "Fairplayer.Sport" that was implemented with preadolescent soccer players (N = 145 preadolescents; aged 9-14 years; mean = 12.2 years) in organized team sport (13 soccer teams). Results revealed a reduction of aggressive behavior in the intervention groups compared to waiting-control groups (small effect size). This effect remained stable 3 months after program implementation. Implications for planning and implementing preventive intervention programs are discussed.

BACKGROUND: Photoangiolytic lasers have broadened the surgical armamentarium for many phonosurgical interventions. However, the pulse dye laser and potassium titanyl phosphate (KTP) laser have technical drawbacks and a smaller spectrum of indications. METHODS AND RESULTS: The new 445 nm wavelength laser, the so-called 'blue laser', proves to show tissue effects comparable to the KTP laser and is also capable of treating subepithelial vessels due to its photoangiolytic properties, it can coagulate and carbonize at higher energy levels, and can be used via glass fibers in non-contact and contact mode for in-office procedures. DISCUSSION: In contrast to the KTP, the new 445 nm laser can also be used as a cutting laser, thus combining very much wanted properties of diode or CO2 lasers with photoangiolytic lasers. Further advantages of the new laser are the; (1) portability of the shoe box sized, shock-proof laser machine for in-office and operating room usage, (2) the selection of pulse rates from continuous wave (cw) to less than a millisecond, (3) stronger tissue effects compared to KTP with similar energy and pulse settings, (4) far better cutting properties than the KTP, and thus (5) more possibilities for usage in laryngology as well as in other fields or surgery. CONCLUSION: We demonstrate the feasibility of the 445 nm laser in several laboratory experiments and show clinical cases where photoangiolysis and cutting was possible. However, this is a preliminary report and further systematic studies in greater numbers are warranted.

Despite the introduction of universal newborn hearing screening (UNHS), unilateral hearing loss (UHL) is sometimes recognized late. This diagnostic delay has adverse repercussions, given the importance of binaural hearing for the development of normal auditory processing. It is incorrect to maintain that unilateral hearing is the minimum requirement for adequate speech development and that hearing aid provision is consequently unnecessary. In our retrospective study, hearing aid provision resulted in improved directional and selective hearing (quiet and noisy environments) and, compared with their chronically ill counterparts, the children in our study displayed superior health-related quality of life (HRQoL) scores in all areas. On the basis of the results, the authors conclude that even mild hearing losses (from an auditory threshold of 30 to 40 dB) should have the opportunity for hearing aid provision. A selective literature review was conducted in PubMed and textbooks and with reference to national and international guidelines. Early diagnosis and treatment of UHL have a positive effect on verbal-cognitive, linguistic, communicative, and socio-emotional development, as demonstrated by neurophysiological studies. Among the treatment modalities with differing effects on the quality of binaural hearing, cochlear implants are now used increasingly in children with hearing loss bordering on deafness. CONCLUSION: Published evidence and clinical experience support early diagnosis and treatment. Wherever feasible, hearing aid provision before or at the end of the first year of life is recommended for children with UHL. What is Known: ⢠Almost 30 years ago, poor academic performance was reported in children with unilateral hearing loss (UHL). ⢠Despite improvements in treatment options, it is traditionally held that unilateral hearing is the minimum requirement for adequate speech development and hearing aid provision is unnecessary. What is New: ⢠Academic and behavioral deficits in children with UHL may be mediated by deficiencies in the default mode network. ⢠Published evidence supports the recommendation for hearing aid provision before or at the end of the first year of life in children with UHL.

Intervention and Therapy for Perpetrators and Victims of Bullying: A Systematic Review Bullying is a form of repeated and aggressive behavior with serious consequences for victims and perpetrators, who often suffer from their experiences long after the bullying episodes have ended. However, the therapeutic treatment of bullying and its consequences represents a neglected topic in bullying research. Objective of the present article is to review publications systematically describing targeted interventions for the treatment of bullying (for victims and perpetrators) and associated disorders. The selection process consisted of a comprehensive systematic search in national and international databases that identified 34 targeted interventions in 31 publications from 14 different countries. The review of ten interventions featuring a controlled design revealed that in particular treatments on both the individual and socio-ecological level (particularly parents) are effective. The remaining 24 treatments lack a controlled evaluation. Two thirds of the interventions focus on victims. In contrast to the treatment of perpetrators, the emphasis here lies on group therapy. Although treatments of bullying apply a range of therapeutic approaches and methods, cognitive behavioral therapy is represented most prominently. As a conclusion one can observe an existing lack of research in evidence-based targeted interventions for the treatment of bullying and its consequences for victims and perpetrators. To our knowledge, this is the first systematic review of therapeutic interventions for bullying in children and adolescents.

The terms used to describe vocal fold motion impairment are confusing and not standardized. This results in a failure to communicate accurately and to major limitations of interpreting research studies involving vocal fold impairment. We propose standard nomenclature for reporting vocal fold impairment. Overarching terms of vocal fold immobility and hypomobility are rigorously defined. This includes assessment techniques and inclusion and exclusion criteria for determining vocal fold immobility and hypomobility. In addition, criteria for use of the following terms have been outlined in detail: vocal fold paralysis, vocal fold paresis, vocal fold immobility/hypomobility associated with mechanical impairment of the crico-arytenoid joint and vocal fold immobility/hypomobility related to laryngeal malignant disease. This represents the first rigorously defined vocal fold motion impairment nomenclature system. This provides detailed definitions to the terms vocal fold paralysis and vocal fold paresis.

For the long-time monitoring of electrocardiograms, electrodes must be skin-friendly and non-irritating, but in addition they must deliver leads without artifacts even if the skin is dry and the body is moving. Today's adhesive conducting gel electrodes are not suitable for such applications. We have developed an embroidered textile electrode from polyethylene terephthalate yarn which is plasma-coated with silver for electrical conductivity and with an ultra-thin titanium layer on top for passivation. Two of these electrodes are embedded into a breast belt. They are moisturized with a very low amount of water vapor from an integrated reservoir. The combination of silver, titanium and water vapor results in an excellent electrode chemistry. With this belt the long-time monitoring of electrocardiography (ECG) is possible at rest as well as when the patient is moving.

The purpose of this study was to measure the relationship between the shear elastic properties of vocal fold with respect to the direction of applied stress. There is extensive published material that quantifies the shear viscoelastic properties of the vocal fold, but as much of these data were obtained using rotating parallel plate rheometers, which are unable to resolve out difference of the shear elastic behaviour with respect to direction, there is very little data that indicates anisotropic behaviour. To overcome this gap in knowledge, the team devised an apparatus that is capable of applying a shear stress in a known direction. A series of measurements were taken at the mid-membranous position, in the transverse and longitudinal directions. Point-specific measurements were performed using fourteen human cadaver excised larynges, which were hemi-sectioned to expose the vocal fold. An extremely low sinusoidal shear force of 1 g was applied tangentially to the membrane surface in both the longitudinal and transverse direction, and the resultant shear strain was measured. With the probe applied to the intact vocal fold, the average ratio of the elasticity in the transverse with respect to the longitudinal direction was 0.55. Further investigation using histological staining of collagens in the lamina propria indicates that there is a visible difference in the general alignment of collagen fibres when comparing the coronal and the sagittal sections. Our conclusion is that there is a quantifiable difference between the shear elastic response of the lamina propria in the longitudinal and transverse directions, and that this could be explained by the difference in alignment of collagen fibres within the lamina propria.

A comparison of tissue cutting effects in excised cadaver human vocal folds after incisions with three different instruments [scalpel, CO2 laser and the picosecond infrared laser-(PIRL)] was performed. In total, 15 larynges were taken from human cadavers shortly after death. After deep freezing and thawing for the experiment, the vocal folds suspended in the hemilarynx were incised. Histology and environmental scanning electron microscopy (ESEM) analyses were performed. Damage zones after cold instrument cuts ranged from 51 to 135 µm, as compared to 9-28 µm after cutting with the PIRL. It was shown that PIRL incision had smaller zones of tissue coagulation and tissue destruction, when compared with scalpel and CO2 laser cuts. The PIRL technology provides an (almost) atraumatic laser, which offers a quantum jump towards realistic 'micro'-phonosurgery on a factual cellular dimension, almost entirely avoiding coagulation, carbonization, or other ways of major tissue destruction in the vicinity of the intervention area. Although not available for clinical use yet, the new technique appears promising for future clinical applications, so that technical and methodological characteristics as well as tissue experiments seem worthwhile to be communicated at this stage of development.

Background: Based on the growing number of families and young children with a refugee background in Germany, day-care teachers face enormous challenges regarding culturally informed practice. The project "Gemeinsam stark durch den Start" (Stronger together by starting together) addresses these challenges on various levels. At the level of day-care teachers, training in culturally informed and sensitive education is combined with reflection sessions about their own attitudes and prevailing intercultural norms, thus contributing to the professionalization of day-care teachers. Aim: This paper focuses on mechanisms of action that contributed to the effectiveness of the training from two perspectives: the day-care teachers' perspective and the trainers' perspective. Methods: Staff members of 11 German day-care centers underwent graded online training sessions (team and in-depths trainings) addressing intercultural topics. All participants were presented with a questionnaire for their training evaluation before and after the training sessions. Also, participants of the in-depths trainings participated in semi-structured interviews on the training. Furthermore, qualitative interviews were conducted with all trainers (N = 4) of the workshops. Results: Day-care teachers evaluated the online training positively, especially the improvement of professionalization and the implementation of training elements. Results reveal that (work-related) reflexive sessions as well as sessions dealing with the implementation of exercise tools into daily practice were rated as fundamental parts in the training. Teachers from high-risk day-care centers estimated the trainings' effectiveness lower than those working in low-risk day-care centers. Qualitative data shows that the day-care teachers are in need of (theoretical) knowledge about all training elements and hands-on advice for dealing with specific situations. Especially day-care teachers within a high-risk environment, who already report having an elevated level of intercultural knowledge and skills, may need a higher dose training while low-risk day-care teachers may profit more from a low threshold training. Conclusion: The introduced training sessions focusing on intercultural sensitivity and competence present an important contribution to the professionalization of day-care teachers in working with children from different cultural backgrounds. Trainings should focus on reflexive elements as well as exercises in perspective taking and provide hands on materials for daily work.
RESUMO
Objective: To evaluate the concept and efficacy of an adjustable implant (Prototype SH30: porcine implant and APrevent® VOIS: human concept) for treatment of unilateral vocal fold paralysis (UVFP) via in vivo mini-pig studies, human computed tomographic (CT) and magnetic resonance (MR) image analysis, ex-vivo aerodynamic and acoustic analysis. Methods: Feasibility testing and prototype implantation were performed using in-vivo UVFP porcine model (n = 8), followed by a dimensional finding study using CT and MR scans of larynges (n = 75) for modification of the implant prototypes. Acoustic and aerodynamic measurements were recorded on excised canine (n = 7) larynges with simulated UVFP before and after medialization with VOIS-Implant. Results: The prototype showed in the in-vivo UVFP porcine model an improved glottic closure from grade 6 incomplete closure to complete closure (n = 5), to grade 2 incomplete closure (n = 2) and grade 3 incomplete closure (n = 1). On human CT/MR scans the identification of the correct size was successful in 97.3% using the thyroid cartilage alar "distance S" as the only parameter, which is an important step towards procedure standardization and implant design. Results were confirmed with implantation in human laryngeal cadavers (n = 44). Measurements of the acoustic and aerodynamic effects after implantation showed a significant decreased phonation threshold pressure (p = .0187), phonation threshold flow (p = .0001) and phonation threshold power (p = .0046) on excised canine larynges with simulated UVFP. Percent jitter and percent shimmer decreased (p = .2976; p = .1771) but not significant. Conclusions: Based on the preclinical results four sizes, differing in medial length, implant width and expansion direction of silicone cushions, seem to be enough to satisfy laryngeal size variations. This concept is significantly effective in medializing UVFP and improving the aerodynamic and acoustic qualities of phonation as reported in a preliminary clinical outcome study with long-term implantation. Level of Evidence: N/A.
RESUMO
The fairplayer.manual is a school-based program to prevent bullying. The program consists of fifteen to seventeen consecutive ninety-minute lessons using cognitive-behavioral methods, methods targeting group norms and group dynamics, and discussions on moral dilemmas. Following a two-day training session, teachers, together with skilled fairplayer.teamers, implement fairplayer.manual in the classroom during regular school lessons. This chapter offers a summary of the program's conception and underlying prevention theory and summarizes the results from two evaluation studies. Standardized questionnaires showed a positive impact of the intervention program on several outcome variables.

The purpose of this study was to describe a simplified arytenoid rotation technique and to test its applicability in excised human larynges. A non-absorbable monofilament thread is slung around the muscular process of the arytenoid cartilage through an external approach. During visual control through flexible endoscopy, two needles and a wire loop needle threader are the only instruments needed. Thread tensioning and fixation results in a stabilized arytenoid adduction. This technique avoids cricothyroid joint disarticulation and leaves the thyroid cartilage intact. The practicability of the technique was proven in five excised larynx experiments. In two clinical cases, the muscular process was slung and pulled with a monofilament thread. Tension in the vector direction parallel to the LCA muscle showed an effective and stable arytenoid rotation with complete closure of the posterior glottis. The rotational effect following sling arytenoid adduction (SAA) is similar to conventional arytenoid adduction surgery outcome. However, SAA is performed from an external approach and avoids dissection of cartilage. Challenging dissections to reach the muscular process are avoided. In some cases of unilateral vocal fold immobility, arytenoid rotation may be performed by using the SAA technique, which allows for an external and extralaryngeal approach. Further studies should assess the clinical value of this technique. In principal, the wire loop needle threader can also be employed for external vocal fold lateralization procedures.
