Voice disorders affect patients profoundly, and acoustic tools can potentially measure voice function objectively. Nonetheless, existing are limited to analysing voices displaying near periodicity, do not account for inherent biophysical nonlinearity non-Gaussian randomness. They directly complex nonlinear aperiodicity, turbulent, aeroacoustic, Often these have clinical usefulness. This paper introduces two new speech analysis: recurrence fractal scaling, which overcome the range limitations...
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has resulted in an unprecedented shutdown social and economic activity, with the cultural sector particularly severely affected. Restrictions on musical performances have arisen from a perception that there is significantly higher risk of aerosol production singing than speaking, based upon high-profile examples clusters COVID-19 following choral rehearsals. However, comparing generation different types vocalization,...
Aerosol particles of respirable size are exhaled when individuals breathe, speak and sing can transmit respiratory pathogens between infected susceptible individuals. The COVID-19 pandemic has brought into focus the need to improve quantification particle number mass exhalation rates as one route provide estimates viral shedding potential risk transmission viruses. Most previous studies have reported concentrations aerosol in an plume. We a robust assessment absolute from measurements minute...
Abstract Background: Voice disorders affect patients profoundly, and acoustic tools can potentially measure voice function objectively. Disordered sustained vowels exhibit wide-ranging phenomena, from nearly periodic to highly complex, aperiodic vibrations, increased "breathiness". Modelling surrogate data studies have shown significant nonlinear non-Gaussian random properties in these sounds. Nonetheless, existing are limited analysing voices displaying near periodicity, do not account for...
Experimental measurements of the superconducting-to-normal phase boundary for a Sierpenskigasket wire network are presented. The fractal phase-boundary curve, ${T}_{c}(H)$, shows four orders dilational invariance and is in excellent quantitative agreement with theoretical predictions. fracton dimension, $\stackrel{-}{\overline{d}}$, has also been measured found to be 1.35 \ifmmode\pm\else\textpm\fi{} 0.02, consistent calculated value 1.365 planar Sierpinski gasket.
The coronavirus disease-19 (COVID-19) pandemic led to the prohibition of group-based exercise and cancellation sporting events. Evaluation respiratory aerosol emissions is necessary quantify exercise-related transmission risk inform mitigation strategies.Aerosol mass emission rates are calculated from concurrent ventilation data, enabling absolute comparison. An aerodynamic particle sizer (0.54-20 μm diameter) samples exhalate within a cardiopulmonary testing mask, at rest, while speaking...
The performing arts have been significantly restricted due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. We report measurements of aerosol and droplet concentrations generated when playing woodwind brass instruments comparisons with breathing, speaking, singing. These were conducted in a room zero number concentration background 0.5-20 µm diameter size range, allowing clear attribution detected particles specific activities. A total 13 examined across 9...
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has brought renewed attention to aerosol and droplet generation. While many studies have robustly quantified (<10 µm diameter) number mass exhalation rates, fewer explored larger This study quantifies droplets (>20 generated by a cohort of 76 adults children using water-sensitive paper deposition approach. Unvoiced voiced activities spanning different levels loudness, lengths sustained phonation, specific manner...
Respiratory particles produced during vocalized and nonvocalized activities such as breathing, speaking, singing serve a major route for respiratory pathogen transmission. This work reports concomitant measurements of exhaled carbon dioxide volume (VCO
The following position statement from the Union of European Phoniatricians, updated on 25th May 2020 (superseding previous issued 21st April 2020), contains a series recommendations for phoniatricians and ENT surgeons who provide and/or run voice, swallowing, speech language, or paediatric audiology services.
Background Persistent throat symptoms are commonly attributed to ‘laryngopharyngeal reflux’. Despite a limited evidence base, these increasingly being treated in primary care with proton pump inhibitors. Objective To assess the value of inhibitor therapy patients persistent symptoms. Design This was double-blind, placebo-controlled, randomised Phase III trial. Setting multicentre UK trial eight ear, nose and departments. Participants A total 346 participants aged ≥ 18 years Reflux Symptom...
IntroductionVoice assessment and treatment involve the manipulation of all subsystems voice production, may lead to production respirable aerosol particles that pose a greater risk potential viral transmission via inhalation pathogens (eg, SARS-CoV-2) than quiet breathing or conversational speech.ObjectiveTo characterise during selection therapy tasks.MethodsWe recruited 23 healthy adult participants (12 males, 11 females), whom were speech-language pathologists specialising in disorders. We...
Tapia syndrome, a rare complication of posterior cervical surgery, characterised by concurrent paralyses recurrent laryngeal branch vagus and hypoglossal cranial nerves, occurred in patient after foraminotomies for radiculopathy. We discuss hypothesised pathophysiology, diagnostic, therapeutic avoidance strategies relevance to prone neurosurgical procedures.
Abstract Clinical acoustic voice recording analysis is usually performed using classical perturbation measures including jitter, shimmer and noise-to-harmonic ratios. However, restrictive mathematical limitations of these prevent for severely dysphonic voices. Previous studies alternative nonlinear random addressed wide varieties vocal pathologies. Here, we analyze a single pathology cohort, testing the performance alongside measures.We present pre- post-operatively in unilateral fold...
AbstractTransmission of an airborne disease can occur when individual exhales respiratory particles that contain infectious pathogens. Surgical face masks are often used to reduce the amount aerosol emitted into environment by while also lowering concentration inhales. Respiratory generation is activity-dependent with high person-to-person variability. Moreover, mask fit differs among people. Here, we measure efficacy surgical (EN14683 Type IIR) in reducing both (0.3 – 20 μm diameter) and...

Pharyngocele is defined as lateral pharyngeal wall herniation located in the piriform recess or at valleculae and was first described 1886. The phenomenon rare. It characterised by bulging of pharynx locally associated with recurrent increase intrapharyngeal pressure, reduced muscle resilience, increasing age. case describes a 51-year-old recreational trumpeter bilateral pharyngoceles that demonstrated when blowing into his instrument, reminiscent bullfrog.

In ophthalmology, there have been few reports of botulinum toxin type-A (BTX-A) injection into the lacrimal gland to treat epiphora. ENT, adductor and abductor (ABSD) spasmodic dysphonia are often treated with BTX-A injections respective overacting vocal cord muscles. We describe a 53-year old male Parkinson's disease who did not respond either gland, for epiphora secondary Parkinsonian-related blink lagophthalmos, or posterior cricoarytenoid (PCA) muscles ABSD.
