Oasys and Occupational Asthma

This website contains information on Occupational Asthma and a free multi award winning computer program called OASYS, which is used to help diagnose Occupational Asthma from serial peak flow records. Oasys shows further information and downloads for the Oasys program. References is a searchable database of more than 5000 published papers in the field of occupational asthma. Causes shows some of the causes of occupational asthma. The Shield scheme reports some statistics for occupational asthma, mainly in the West midlands region, UK. BOHRF shows the evidence based occupational asthma guidelines for the UK. The interactive Case Histories are a learning resource for interested health professionals. There are also Medics, Specialists, Employers and Worker sections.

Comments for the paper: "Occupational asthma associated with bleached chlorine-free cellulose dust in a sanitary pad production plant.", 2018, Am J Industr Med
This is a detailed report of occupational asthma confirmed by SIC and Oasys PEF analysis with exposure to ozone bleached cellulose at low concentrations. A search for protein contaminants and specific IgE were all negative. Cellulose is a polysaccharide derived from wood, mostly pine species. This case has significant implications for others with occupational asthma from paper and cardboard dust, where symptomatic occupational asthma occurs but a specific cause has not been identified.

Comments for the paper: "Changes in occupational asthma during four decades in Slovakia, Central Europe", 2018, Ann Agric Environ Med
The study included the patients with OA who were in the database of the Department of Occupational Medicine and Clinical Toxicology at the Louis Pasteur University Hospital in Košice, Slovakia. The database comprises patients who had been diagnosed with OA and reported by this department during the period 1980–2016. At present, the standard procedure for the confirmation of asthma is initiated by the admission of the patient who suffers from respiratory problems at work to the ambulance or department of occupational medicine. In the Slovak Republic, the centre for occupational respiratory diseases is the Department of Occupational Medicine and Clinical Toxicology of Louis Pasteur University Hospital in Košice. On admission, all patients undergo a basic examination by a specialist, followed by lung function tests. An immunoallergological examination is then performed. This consists of confirmation of sensitization to a suspected allergen of the occupational environment, if available. Simultaneously, the sensitization to common inhalant airborne allergens is tested, and skin prick tests or serum specific IgE antibodies test are performed. Positivity of skin tests (prick test or epicutaneous tests) or blood tests with the history of typical respiratory symptoms at the workplace makes the diagnosis of occupational asthma very probable. After the assessment of work conditions by the hygienic worker, it should be decided whether bronchial asthma is considered an occupational. Another diagnostic method is the elimination/resume test. The results of elimination/resume test are considered positive if the clinical symptoms are absent while the patient is out of the workplace, and the worsening of the clinical state is observed after repeated exposition.

The Website

This website is run by the Oasys research group, part of the Midland Thoracic Society, UK. We are an independent group of clinicians and researchers, and run a clinical service for workers with occupational lung disease as part of the British National Health Service. We have developed the Oasys program to help ourselves and others in the diagnosis of occupational asthma. We have no specific funding, relying on research grants and the enthusiasm of our group. The website is written by Cedd Burge, who receives some funding from the group. The group meets about every 6 weeks on a Wednesday evening, as shown below.



As a casual user of this site (without logging in or registering) you can view all the information and use all the contact pages. Registered and logged in users (registering is free and we won't abuse your email) can download and use the Oasys program, ask and reply to questions in the forums, leave comments, add new references, add abstracts and full text links to existing references, answer questions in the case histories and provide evidence and suggest questions for future evidence based guidelines.

If you would like to be added to the list of known authors or collaborators then please register with the website (if you have not already done so) and then get in touch from the contact page. Once we have set the page up you will be able to edit it yourself and indicate which references you have written. Your picture will then be displayed along with each of these references. If you are already in these lists and would like to edit your page then please register with the website and then get in touch from the contact page.
