Continuous laryngoscopy during provocation in the assessment of inducible laryngeal obstruction

Article

Transient paradoxical closure of the larynx, occurring in the absence of any underlying structural or neurological defect, is a recognized cause of paroxysmal breathlessness and wheeze. This phenomenon, most commonly termed vocal cord dysfunction and more recently termed inducible laryngeal obstruction (ILO),1 is often misdiagnosed and mistreated as asthma.2, 3 This may be explained by the lack of a robust, accepted diagnostic methodology.4, 5

Honorary Consultant in Occupational Lung Disease and Asthma

Jo is an Honorary Respiratory Consultant in occupational lung disease and asthma at Royal Brompton Hospital and Senior Clinical Research Fellow at the National Heart and Lung Institute, Imperial College.

Her research is primarily focused on the respiratory heath of working populations including firefighters and individuals exposed to silica. She has been awarded funding to establish a UK Silicosis Registry. She is clinical advisor to the All-Party Parliamentary Group on Respiratory Health (silicosis). She is a member of the Group of Occupational Respiratory Disease Specialists (GORDS) and recent Chair of the British Thoracic Society Occupational and Environmental Lung Disease Specialist Advisory Group (2021-2024).  

Exacerbation patterns in adults with asthma in England. A population-based study

Article

Rationale: Asthma is heterogeneous and knowledge on exacerbation patterns is lacking. Previous studies have had a relatively short follow-up or focused on severe disease.

Objectives: To describe exacerbation patterns over a prolonged follow-up in a population that includes patients of all disease severity.

Follow-up survey of patients with occupational asthma

Article
Using a postal questionnaire, we surveyed all patients attending our specialist occupational lung disease clinic 1 year after having received a diagnosis of OA due to a sensitizer (n = 125). We enquired about their current health and employment status and impact of their diagnosis on various aspects of their life. Additional information was collected by review of clinical records.

Laboratory animal allergy is preventable in modern research facilities

Article
We surveyed 750 laboratory animal workers and measured airborne Mus m 1 (mouse allergen) levels in seven UK institutions. We compared the prevalence of sensitisation to mouse proteins (by specific IgE assay or skin prick test) and of work-related allergic symptoms in IVC-only and open cage units.

Occupational contributions to Interstitial Lung Disease

Editorial
  • Globally, coal workers pneumoconiosis, silicosis, and asbestosis remain the most important pneumoconioses.
  • Idiopathic pulmonary fibrosis (IPF) and asbestosis can be challenging to differentiate clinically, and there is clear evidence for an occupational contribution to IPF.
  • Bacterial contamination of metal working fluid has recently emerged as an important cause of occupational hypersensitivity pneumonitis.

Occupational exposure to particulate matter and staff sickness absence on the London underground

Article

The London Underground (LU) employs over 19,000 staff, some of whom are exposed to elevated concentrations of particulate matter (PM) within the network. This study quantified the occupational exposure of LU staff to subway PM and investigated the possible association with sickness absence (SA).

A job exposure matrix to quantify subway PM2.5 staff exposure was developed by undertaking measurement campaigns across the LU network. The association between exposure and SA was evaluated using zero-inflated mixed-effects negative binomial models.
