INTRODUCTION: Human development includes lots of physical and emotional changes. The human voice depends on age. Voice production is a complex physiological and acoustic phenomenon that depends on many factors such as structure, hormone level, degree of fatigue or nutrition and hydration of the body, systemic diseases, and emotional state. All these factors can be present in anorexia nervosa (AN), such as excessive weight loss, generated hydro-electrolytic changes, nutritional deficiencies, hormonal disturbances in the function of the hypothalamic-pituitary-adrenal axis, the hypothalamic-pituitary-thyroid axis, the hypothalamic-pituitary-ovarian axis, and emotional distress...

OBJECTIVE: To systematically evaluate the clinical efficacy and safety of proton-pump inhibitors (PPIs) combined with alginate versus PPIs alone in the treatment of gastroesophageal reflux disease (GERD). METHODS: Randomised Controlled Trials (RCTs) of PPIs combined with alginate and PPIs alone for the treatment of GERD in PubMed, Embase, and The Cochrane Library were searched and screened, and the risk assessment of bias and statistical analysis were performed using Rev Man 5...

INTRODUCTION: Health literacy, a strong indicator of health outcomes, is an important aspect of good patient care. With an increasing reliance on the Internet for health information, online patient materials should be easily understood by the average reader. The American Medical Association (AMA) and National Institutes of Health (NIH) recommend that patient education materials be written at a sixth-grade level. Creating effective digital information requires careful consideration of not only word choice, but also many other factors including actionability, comprehensiveness, evidence, and visual organization...

INTRODUCTION: We investigated transcutaneous laryngeal ultrasonography (TLUS) for assessing vocal fold (VF) mobility during thyroid and parathyroid surgeries, emphasizing its precision and utility in signal loss scenarios. METHODS: Between October 2020 and January 2023, we performed TLUS, Doppler sonography, laryngeal twitch response (LTR) palpation, and electromyography (EMG) to monitor recurrent laryngeal nerve function during neck surgeries. Postoperatively, the VF activity was verified using fiberoptic video laryngoscopy (FL)...

OBJECTIVE: Mature vocal fold nodules and fibrous phono-traumatic lesions that have failed standard voice therapy can be challenging. Autologous platelet-rich plasma (PRP) is rich in growth factors and easily obtained from a simple blood draw. Growth factor injection into the vocal folds may reverse the scar and inflammation in recalcitrant, bilateral phono-traumatic lesions such as mature vocal fold nodules. This study reports the short-term (3months) voice results after PRP injection in 11 subjects with recalcitrant, bilateral phono-traumatic lesions that have failed voice therapy...

OBJECTIVE: 1. To investigate the discriminatory and diagnostic power of nonlinear dynamic analysis measures concerning voices from normal, benign, and malignant voice disorders. 2. To study the correlations of nonlinear dynamic analysis measures with perceptual ratings to evaluate the reliability of the objective acoustic analysis in predicting severity of voice. METHOD: The perturbation analysis metrics used were Jitter%, Shimmer%, and signal-to-noise ratio. The nonlinear dynamic analysis metrics used were spectrum convergence ratio (SCR), nonlinear energy difference ratio (NEDR), and rate of divergence (ROD)...

The trombone and the male voice cover similar frequency ranges and, at a physical level, the basic anatomies of the voice and the trombone show some qualitative similarity: both have two vibrating flaps of muscular tissue (the vocal folds and the trombonist's lips, respectively), and in each case, these are loaded acoustically by resonant ducts both upstream and downstream. There are also large differences. For example, the downstream ducts differ in length. The trombone usually operates with an oscillation frequency close to that of one of the downstream resonances; this is only occasionally true of the voice...

BACKGROUND AND PURPOSE: Laryngeal transplantation (LT) remains an infrequently performed procedure due to well-defined and limited medical indications. The challenges include a very complicated surgery, continuous immunosuppressive treatment, as well as post-transplant rehabilitation of voice, speech, and swallowing. The aim of this paper is to describe a model of voice and speech rehabilitation after LT, based on our own experience. STUDY DESIGN: Observational study...

OBJECTIVE: The ability to perceive strain or tension in a voice is critical for both speech-language pathologists and singing teachers. Research on voice quality has focused primarily on the perception of breathiness or roughness. The perception of vocal strain has not been extensively researched and is poorly understood. METHODS/DESIGN: This study employs a group and a within-subject design. Synthetic female sung stimuli were created that varied in source slope and vocal tract transfer function...

OBJECTIVE: This study aims to is to develop a disorder-specific patient-reported outcome measure to be used in Islamic clergymen with voice disorders and to investigate its validity and reliability. METHODS AND PROCEDURES: Employing an exploratory sequential mixed-methods design, this study conducted in two phases. Initially, semistructured interviews were conducted with 10 clergymen experiencing voice disorders. Subsequently, the questionnaire underwent rigorous validation, encompassing content, construct, and criterion validity assessments, in addition to test-retest reliability and internal consistency analyses...

OBJECTIVE: To develop a novel Laryngopharyngeal Reflux Disease (LPRD) model in Bama pigs through endoscopic cricopharyngeal myotomy. METHODS: A total of eight 8-month-old Bama pigs were randomly assigned to either the control or surgery group. Prior to intervention, upper esophageal sphincter (UES) manometry and laryngopharyngeal Dx-pH monitoring were conducted to establish baseline physiological parameters for each pig. Subsequently, the surgery group underwent endoscopic cricopharyngeal myotomy, while the control group did not...

BACKGROUND: Currently, little is known about the characteristics of individuals presenting for physiotherapy care with voice and throat problems. PURPOSE: The aim of this study is to describe the demographic and clinical characteristics of individuals presenting to physiotherapy for voice and throat-related problems, and to use this information to clarify the role of physiotherapy in the management of people with voice and throat problems. METHODS: A retrospective clinical case notes review was conducted of all clients who accessed physiotherapy for voice and throat problems at a private practice based in Christchurch within a 12-month period from 1st October 2020 to 1st October 2021...

OBJECTIVE: The aim of the study is to investigate the use of incidences and characteristics of Prevocalic Electroglottographic Signal (PVES) derived from electroglottography (EGG) in characterizing glottal stops (GS) in cleft palate speech. METHODS: Mandarin nonaspirated monosyllabic first-tone words were used for the speech sampling procedure. A total of 1680 utterances (from 83 patients with repaired cleft palates) were divided into three categories based on the results of auditory-perceptual evaluation of recorded speech sounds by three independent reviewers: [Category A (absence of GS agreed by all three reviewers) (n = 1192 tokens), Category B (two out of three reviewers agreed on the presence of a GS) (n = 181 tokens) and Category C (all three reviewers agreed on the presence of a GS) (n = 307 tokens)]...

BACKGROUND: Inducible laryngeal obstruction (ILO) is the adduction of the true vocal folds during inspiration or, less frequently, expiration. Its etiology is unknown. PURPOSE: This study aimed to identify ILO as a possible cause of shortness of breath (SOB) in post-COVID-19 patients. METHODS: A retrospective study was conducted on 59 post-COVID-19 adults complaining of SOB. We collected the cases' clinical and chest imaging data, including demographic data, pulmonary function test (PFT), CT chest, and laryngeal endoscopic examination...

OBJECTIVES: Special education teachers (SETs) work with students with disabilities. To get and keep these students' attention during the lesson, they may use their voices with high loudness and frequent pitch changes. These situations can be tiring for their voices and affect their vocal health. This study aimed to compare SETs' voice fatigue, reflux symptoms, and self-assessments according to their voice use habits in their work and social lives. METHODS: A total of 208 SETs were included...

The Glottal Area Waveform (GAW) is an important component in quantitative clinical voice assessment, providing valuable insights into vocal fold function. In this study, we introduce a novel method employing Variational Autoencoders (VAEs) to generate synthetic GAWs. Our approach enables the creation of synthetic GAWs that closely replicate real-world data, offering a versatile tool for researchers and clinicians. We elucidate the process of manipulating the VAE latent space using the Glottal Opening Vector (GlOVe)...
