Diagnosis of vocal cord dysfunction/inducible laryngeal obstruction: An International Delphi Consensus Study.

Background: Vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO) is characterized by breathing difficulties in association with excessive supraglottic or glottic laryngeal narrowing. The condition is common and can occur independently; however, it may also be comorbid with other disorders or mimic them. Presentations span multiple specialties and misdiagnosis or delayed diagnosis is commonplace.

Computed Tomography Imaging of the Larynx for Diagnosis of Vocal Cord Dysfunction.

BACKGROUND: Vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO) is characterized by breathlessness and often mimics or accompanies severe asthma. The disorder occurs intermittently, and the diagnosis is established by using laryngoscopy. Dynamic computed tomography (CT) imaging of the larynx at low-radiation doses has the potential to provide an alternative method to make the diagnosis of VCD/ILO.

Diagnosis of vocal cord dysfunction / inducible laryngeal obstruction-A Delphi study protocol.

Introduction: Currently there is no consistent and widely accepted approach to the diagnosis of vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO). Harmonised diagnostic methods are vital to enable optimal diagnosis, advance management and enable research. We aim to obtain consensus on how expert clinicians recognise and diagnose VCD/ILO.

Innovations during the Covid-19 pandemic to maintain delivery of care for vocal cord dysfunction (VCD) in a multidisciplinary team (MDT) clinic.

Multidisciplinary team clinic for vocal cord dysfunction directs therapy and significantly reduces healthcare utilization.

Background And Objective: Multidisciplinary team (MDT) clinics use an integrated approach to individualize care of complex medical conditions. Vocal cord dysfunction (VCD) is a challenging condition that is likely to benefit from MDT clinics but this has not been researched.

Methods: A prospective observational cohort study of a novel VCD MDT clinic was conducted in patients with suspected VCD.

A national level assessment of metal contamination in bats.

Many populations of bat species across the globe are declining, with chemical contamination one of many potential stressors implicated in these demographic changes. Metals still contaminate a wide range of habitats, but the risks to bats remain poorly understood. This study is the first to present a national scale assessment of toxic metal (Cd, Pb) and essential trace metal (Cu, Zn) concentrations in bats.

Clinical outcomes in a high nursing ratio ward setting for children with obstructive sleep apnea at high risk after adenotonsillectomy.

Background: In 2012 clinical management of children having adenotonsillectomy (AT) for suspected obstructive sleep apnea (OSA) at our tertiary centre changed based on previous research: children with severe obstructive sleep apnea (OSA) at increased risk of post-operative respiratory adverse events (AE) identified using home overnight oximetry or polysomnography (PSG) were managed post-operatively in a high nurse/patient ratio unit in the ward (high acuity unit, HAU) rather than in the intensive care unit (ICU) as previously.

Objectives: To examine the post-operative respiratory AE post AT in HAU.

Methods: A retrospective audit was performed of children having AT on the HAU list from Oct 2012-Sept 2014, identifying clinical information, pre-operative testing for OSA and post-operative course.

Fur: A non-invasive approach to monitor metal exposure in bats.

This paper presents a novel assessment of the use of fur as a non-invasive proxy to biomonitor metal contamination in insectivorous bats. Concentrations of metals (cadmium, copper, lead and zinc) were measured using ICP-MS in tissues (kidneys, liver, stomach and stomach content, bones and fur) obtained from 193 Pipistrellus pipistrellus/pygmaeus bats. The bats were collected across a gradient of metal pollution in England and Wales.

Abnormal vocal cord movement treated with botulinum toxin in patients with asthma resistant to optimised management.

Background And Objective: Abnormal vocal cord movement may coexist with asthma and cause additional upper/middle airway obstruction. The condition may be a form of muscular dystonia that could contribute to asthma resistant to optimised treatments. Botulinum toxin causes temporary paralysis of muscle and may be an effective local treatment that improves asthma control.

Isotopic and elemental data for tracing the origin of European olive oils.

H, C, and O stable isotope ratios and the elemental profile of 267 olive oils and 314 surface waters collected from 8 European sites are presented and discussed. The aim of the study was to investigate if olive oils produced in areas with different climatic and geological characteristics could be discriminated on the basis of isotopic and elemental data. The stable isotope ratios of H, C, and O of olive oils and the ratios of H and O of the relevant surface waters correlated to the climatic (mainly temperature) and geographical (mainly latitude and distance from the coast) characteristics of the provenance sites.

The effect of consumption of selenium enriched rye/wheat sourdough bread on the body's selenium status.

The potential of selenium-enriched rye/wheat sourdough bread as a route for supplementing dietary selenium intakes is reported. In addition to their normal diets, 24 female volunteers (24 to 25 years old) were fed either selenium-enriched bread or non-enriched bread each day (68.02 and 0.

Arsenic in seaweed--forms, concentration and dietary exposure.

This study has measured the content of total and inorganic forms of arsenic in seaweed available on retail sale for consumption, to provide data for dietary exposure estimates and to support advice to consumers. A total of 31 samples covering five varieties of seaweed were collected from various retail outlets across London and the internet. All of the samples were purchased as dried product.

Absorption of selenium from wheat, garlic, and cod intrinsically labeled with Se-77 and Se-82 stable isotopes.

There is limited information on the absorption of selenium from different foods in humans because of technical difficulties associated with isotopic labeling of dietary selenium. Wheat, garlic, and cod fish were intrinsically labeled with Se-77 or Se-82 stable isotopes. Labeled meals were fed in random order to 14 adults, with a minimum washout period of six weeks between each test meal.

Long-term results of type II thyroplasty for adductor spasmodic dysphonia.

Objectives: To assess the outcome of type II thyroplasty in the treatment of adductor spasmodic dysphonia (ASD).

Study Design: Prospective case series.

Methods: Thirteen patients with the diagnosis of ASD who were previously treated successfully with botulinum toxin therapy were recruited.
