European clinical practice guideline: managing and treating laryngopharyngeal reflux disease.

Objective: To propose a European consensus for managing and treating laryngopharyngeal reflux disease (LPRD) to guide primary care and specialist physicians.

Methods: Twenty-three European experts (otolaryngologists, gastroenterologists, surgeons) participated in a modified Delphi process to revise 38 statements about the definition, clinical management, and treatment of LPRD. Three voting rounds were conducted on a 5-point scale and a consensus was defined a priori as agreement by 80% of the experts.

Validity and Reliability of the German Vocal Fatigue Index in Adults With Voice Disorders.

Purpose: Vocal fatigue-related symptoms, frequent in patients with voice disorders, are reliably quantifiable with the Vocal Fatigue Index (VFI) in several languages. The main aim of this work was to investigate the content and construct validity of the German Vocal Fatigue Index (VFI-D) by comparison with the German Voice Handicap Index 9 international (VHI9i) and the Vocal Tract Discomfort Scale (VTD). Moreover, the scale and retest reliability were investigated.

[Gastric vs. supragastric belching, singultus, aerophagia, and differential diagnoses : An interdisciplinary perspective for otorhinolaryngologists].

Belching is the act of expelling air from the stomach or esophagus into the pharynx. Although the process is regarded as physiological, excessive belching might be associated with a significant burden for affected patients in the sense of a belching disorder. Diagnosis of a belching disorder is often challenging, and its differentiation from other conditions such as rumination syndrome, singultus, or aerophagia can be difficult.

[Help, I can't burp! A brief overview and case discussion of retrograde cricopharyngeal dysfunction].

In this short communication, we discuss the recently described syndrome of retrograde cricopharyngeal dysfunction (R-CPD) with its first description in 2019 by the laryngologist Dr. Bastian. Diagnosis is generally based on typical clinical symptoms, e.

Consensus for voice quality assessment in clinical practice: guidelines of the European Laryngological Society and Union of the European Phoniatricians.

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.

[Patient-reported outcome measures for assessing health-related quality of life in patients with voice and swallowing disorders].

Standardized and validated patient surveys in the form of questionnaires are becoming increasingly important in otorhinolaryngology. Subjective symptoms and functional limitations but also health-related quality of life are assessed with so-called patient-reported outcome measures (PROMs). Besides patient history and objective findings, these questionnaires can be applied as another important source for ensuring the quality of patient-centered care.

[Current possibilities and challenges in the treatment of laryngopharyngeal reflux].

Laryngopharyngeal reflux (LPR) is characterized by backflow of gastric or gastroduodenal content and gases into the upper aerodigestive tract, which can damage the mucus membranes of the larynx and pharynx. It is associated with a variety of symptoms such as retrosternal burning and acid regurgitation, or other unspecific symptoms such as hoarseness, globus sensation, chronic cough, or mucus hypersecretion. Due to the lack of data and the heterogeneity of studies, diagnosis of LPR is problematic and challenging, as recently discussed.

[Transcultural German translation of the reflux symptom score-12 questionnaire].

In addition to clinical and instrumental methods as well as medical history, questionnaires are well-established tools in the diagnosis of laryngopharyngeal reflux (LPR). Recently, the reflux symptom score (RSS) as well as the short version of it, the RSS-12, which are self-administered patient-reported outcome questionnaires, have been published as an alternative to the well-established reflux symptom index (RSI). The RSS-12 assesses severity and frequency of LPR symptoms as well as the impact on quality of life and has been shown to have high reliability and validity.

[Office-based phonosurgery].

Significant and new impulses regarding the treatment concept for outpatient phonosurgery on unsedated patients are currently coming from various Anglo-American authors. These "office-based procedures" have been propagated as an alternative to many conventional surgical interventions under anesthesia. The main reason for this remarkable development is the use of new endoscopic techniques in combination with photoangiolytic laser (KTP and blue laser), which allow safe and efficient phonosurgical procedures.

Assessment of Surgical Complications With Respect to the Surgical Indication: Proposal for a Novel Index.

The Clavien-Dindo classification is a broadly accepted surgical complications classification system, grading complications by the extent of therapy necessary to resolve them. A drawback of the method is that it does not consider why the patient was operated on primarily. We designed a novel index based on Clavien-Dindo but with respect to the surgical indication.

Effects of Fundamental Frequency, Vocal Intensity, Sample Duration, and Vowel Context in Cepstral and Spectral Measures of Dysphonic Voices.

Purpose Smoothed cepstral peak prominence (CPPS) and harmonics-to-noise ratio (HNR) are acoustic measures related to the periodicity, harmonicity, and noise components of an acoustic signal. To date, there is little evidence about the advantages of CPPS over HNR in voice diagnostics. Recent studies indicate that voice fundamental frequency (F0) and intensity (sound pressure level [SPL]), sample duration (DUR), vowel context (speech vs.

Fundamental Frequency and Intensity Effects on Cepstral Measures in Vowels from Connected Speech of Speakers with Voice Disorders.

Objective: Cepstral peak prominence (CPP) and smoothed CPP (CPPS) have been described as reliable parameters to detect overall dysphonia in standardized connected speech samples. Recent studies indicate that vocal intensity (sound pressure level, SPL) and fundamental frequency (f) changes may influence cepstral measurement results in healthy speakers. The main aim of the present work was to investigate the effects of prosody related SPL and f variations on cepstral measures in speech of adults with voice disorders.

Cervical Spine Disability in Correlation with Subjective Voice Handicap in Patients With Voice Disorders: A Retrospective Analysis.

Objective: Neck muscle dysfunction has been considered as risk factor or consequence of voice disorders. This study investigates the correlation between neck and voice-related subjective symptoms in patients with voice disorders.

Study Design: Retrospective case-control study.

Reliable acoustic measurements in children between 5;0 and 9;11 years: Gender, age, height and weight effects on fundamental frequency, jitter and shimmer in phonations without and with controlled voice SPL.

Background: Current pediatric voice assessment guidelines include instrumental measurements of fundamental frequency (F0) and the perturbation indices jitter and shimmer. In children below 10 years, gender, age, height and weight effects on these parameters have been inconsistently characterized. Recent research in healthy children showed, that differences in habitual speaking voice intensity (voice SPL) under the usual assessment procedure significantly affect jitter and shimmer.

Clinical relevance of speaking voice intensity effects on acoustic jitter and shimmer in children between 5;0 and 9;11 years.

Background: Current voice assessment recommendations for dysphonic children comprise instrumental acoustic measurements of the perturbation parameters jitter and shimmer. In healthy adults and children changes in speaking voice sound pressure level (voice SPL) have significant confounding effects on both parameters. In adults these effects were considerably reduced in phonations with controlled voice SPL >80dBA (10cm distance).

Feeding dystonia in McLeod syndrome.

Background: The X-linked McLeod syndrome belongs to the group of neuroacanthocytosis syndromes and has a Huntington-disease-like phenotype with a choreatic movement disorder, cognitive alterations, and psychiatric symptoms. Another neuroacanthocytosis syndrome, the autosomal recessive chorea-acanthocytosis, has a similar presentation, but distinct clinical features, believed to be characteristic, such as tongue protrusion dystonia, feeding dystonia, and rubber-man-like appearance.

Methods: This work comprised a case series of 3 patients with McLeod syndrome.
