Objective: Benign phonotraumatic lesions of the vocal folds (BVFLs) are typically seen in younger female patients with high vocal loads. Hemorrhagic polyps (HPs) do not fit the classic paradigm of most BVFLs, as they tend to occur in an older population, have a male predominance, and report to result from a vocal accident. We present one of the largest cohorts of HPs, to reexamine their etiology and clinical features.

Purpose: To establish normative values for the OMNI-Vocal Effort Scale (VES) in healthy adults without voice complaints. Secondary objective is to determine if there are differences in perceived vocal effort across age groups and between sexes.

Study Design: Prospective data collection across groups.

Purpose: Successful microlaryngeal surgery relies on an adequate laryngeal exposure. Recognizing the likelihood of challenging exposure prior to microlaryngeal surgery may assist in selecting the appropriate surgical approach and even prompt consideration of alternative treatment options. We aim to apply the mini-Laryngoscore, a preoperative assessment tool, to our study population and incorporate novel variables to optimize the prediction model.

Objectives: There is currently a lack of objective treatment outcome measures for transgender individuals undergoing gender-affirming voice care. Recently, Bensoussan et al developed an AI model that is able to generate a voice femininity rating based on a short voice sample provided through a smartphone application. The purpose of this study was to examine the feasibility of using this model as a treatment outcome measure by comparing its performance to human listeners.

Introduction: Laryngeal dystonia (LD) is a focal dystonia affecting the intrinsic laryngeal muscles. Clinical diagnosis requires subjective evaluation by experienced clinicians and is primarily based on auditory-perceptual assessment. Several speech tasks are widely accepted to elicit diagnosis specific auditory-perceptual symptoms of glottal stops in adductor LD or breathy breaks in abductor LD in spoken English.

In the present work, different configurations of nt iartificial neural networks (ANNs) were analyzed in order to predict the experimental diameter of nanofibers produced by means of the electrospinning process and employing polyvinyl alcohol (PVA), PVA/chitosan (CS) and PVA/ (Av) solutions. In addition, gelatin type A (GT)/alpha-tocopherol (α-TOC), PVA/olive oil (OO), PVA/orange essential oil (OEO), and PVA/anise oil (AO) emulsions were used. The experimental diameters of the nanofibers electrospun from the different tested systems were obtained using scanning electron microscopy (SEM) and ranged from 93.

Objectives: The COVID-19 pandemic expanded the use of telemedicine, but there is no literature exploring both patient and provider satisfaction specifically in the provision of voice therapy. This study aims to investigate patient and provider satisfaction with virtual voice therapy, its associated factors, and any correlation between the two.

Methods: Cross-sectional study.

Introduction: The Voice Handicap Index 10 (VHI-10) has been translated to many languages. There are substantial differences between the translation methods. Translated questionnaires without appropriate linguistic validation may not capture cultural differences or be understood by the participants in the manner intended by the original developers.

Introduction: It is well understood that hearing plays an important role in accurate vocal production. Singers in particular rely on auditory cues and auditory feedback to reproduce specific pitch contours. Therefore, even mild hearing loss may have a detrimental effect on a singer's ability to perform.

Purpose: Society has become increasingly dependent on telecommunication, which has been shown to negatively impact vocal function. This study explores the use of sidetone regulation during audio-visual communication as one potential technique to alleviate the effects of telecommunication on the voice.

Method: The speech acoustics of 18 participants with typical voices were measured during conversational tasks during three conditions of sidetone amplification: baseline (no sidetone amplification), low sidetone amplification, and high sidetone amplification.

Introduction: Vocal fold atrophy and scar can lead to loss of normal superficial lamina propria, negatively affecting the vibratory function of the vocal fold. These changes can lead to dysphonia, vocal fatigue, decreased volume, and altered pitch. Treatment options for these conditions are limited.

Acute vestibular syndrome is most often caused by vestibular neuritis or stroke, although demyelinating diseases may be responsible for 4% of all AVS episodes. The authors present the case of a previously healthy 17-year-old female patient complaining of spontaneous vertigo and right-sided hearing loss. Otoneurological examination suggested a peripheral vestibular cause and video head impulse test revealed a reduced vestibulo-ocular reflex gain.

Purpose: The authors aim to review available reports regarding laryngeal candidiasis and describe the existing evidence on the demographics, clinical manifestations, diagnosis, therapeutic options, and outcomes of this infection.

Methods: A review of articles on laryngeal candidiasis was conducted using PubMed database from its inception through July 2019.

Results: Patients were mainly females presenting with complaints of dysphonia and associated gastroesophageal reflux history or inhaled corticosteroids use; although local predisposing factors were common, most patients were immunocompetent.

Objectives: To analyse the possible changes on the acoustic parameters and auditory-perceptive characteristics of children's voice after adenoidectomy with or without tonsillectomy.

Methods: Prospective cohort study of children aged 5-12 years at one month before surgery (t0) and one (t1), three (t3) and six (t6) months after adenoidectomy with or without tonsillectomy. On each assessment the acoustic parameters (fundamental frequency, jitter %, shimmer % and harmonics-to-noise ratio) and auditory-perceptive analysis (nasal resonance, loudness, pitch, GRBAS scale and maximum phonation time) were recorded.

Cytosine, a DNA and RNA building-block, and Metformin, the most widely prescribed drug for the treatment of Type 2 were made to react separately with ammonium or sodium metavanadates in acidic aqueous solutions to obtain two polyoxovanadate salts with a 6:1 ratio of cation-anion. Thus, compounds [HCyt][VO]·4HO, and [HMetf][VO]·6HO, (where HCyt = Cytosinium cation, [CHNO] and HMetf = Metforminium cation, [CHN]) were obtained and characterized by elemental analysis, single crystal X-ray diffraction, vibrational spectroscopy (IR and Raman), solution V-NMR, thermogravimetric analysis (TGA-DTGA), as well as, theoretical methods. Both compounds crystallized in space group with = 1/2, where the anionic charge of the centrosymmetric ion [VO] is balanced by six Cytosinium and six Metforminium counterions, respectively.

Angiosarcoma of the head and neck, a rare malignancy, is associated with a high degree of invasiveness and poor survival. A high level of suspicion followed by histopathologic and immunohistochemical studies is warranted in order to arrive at a well-timed and accurate diagnosis. We report the case of a 56-year-old man who developed an unusually small neoplasm in the nasal columella.
