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 4,500 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.

Any problems with inhaling oxalic acid?
A popular new approach for dealing with varroa mites on honey bees. These mites were inadvertently introduced from Asia by commercial beekeepers a few years ago and, with very few exceptions such as colonies on the Isle of Man, they have essentially become endemic within all bee colonies across Europe. Left untreated, a bee colony will completely collapse after about two years because it will have become so weakened by the parasitism and a range of opportunistic infections. An “integrated pest management” approach is adopted, in which a range of strategies are used at different times of the year to try and induce reasonable mite falls through the open mesh floor of the hive. No individual strategy is brilliant (and the bees are quickly re-contaminated due to bees drifting between hives, etc) but the combined effect is “good enough”. In the last couple of years some of us have started blocking up the hive floor and hive entrance after introducing a teaspoon of oxalic acid powder into the hive on a small heater unit that is powered by a car battery. After a couple of minutes you can start to see the vapour come out of any leaks in the hive... and you can typically smell it too (not pleasant). The bees buzz very loudly for an hour or so (presumably this is their equivalent of choking??) and the mite drop is generally phenomenal. When performing this procedure, we choose a still night and stand as far from the hive as is possible whilst keeping the heater unit in place (Our nostrils are perhaps 1 to 1.5 metres from the hive). Some of us wear gloves, masks and goggles whilst others don’t. There is much debate amongst beekeepers about the risk of lung damage using such treatment. Personally, I assume that the vaporized oxalic acid granules have such a large diameter that they are very unlikely to get further down the airway than the oropharynx. Would you be able to advise me: • What the size of the risk might be to beekeepers? • The nature of the lung damage? Would “small doses” produce superficial reversible damage to the epithelium with only “larger doses” causing scarring and other irreversible damage? What dose sizes are we talking about? • What scientific papers (if any) I could read on oxalic acid lung damage (I have not been able to find any so far)?

Comments for the paper: "Asthma prevalence in Olympic summer athletes and the general population: An analysis of three European countries", 2015, Respir Med
Occupational asthma in professional swimming athletes is well recognised, probably due to inhaled chloramines, and is found in this epidemiological study. It also shows increased asthma in high-level endurance athletes over non-indurance athletes suggesting that exercise or hyperventilation alone may cause asthma. Other studies have shown more asthma in cold air athletes suggesting that hyperventilation with cold dry air causes asthma

I can't get the data sheet to come up for a new person. What's up with that? How can I?

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.
