FeNO showed no significant change at 7 hours, an increase >10ppb at 24 hours had a sensitivity of 37% for a specificity of 81%. The next stage would be to test the 2.2% increase in eosinophils is subjects whose challenges were equivical in terms of FEV1 decline, or who showed a <20% FEV1 fall post challenge.

I worked with waste transformer oils in an unsuitable environment for 10 months suffering from lung problems initially burning and shortness of breath. The company whilst admittiing fume exposure have refused to state what fumes (as thay probabaly dont truely know as it was a waste product). To the best of my knowledge they would have included mineral oil, furfuraldehyde, carbon monoxide, acetalyde, alcohols, solvents (cleaning the bottles), poly chlorinated biphenols, ,various metals,maybe BHT and other unknown oil preservatives at unknown levels. No monitoring or PPE and no complete safety data sheet for this waste product. I also sourced latex gloves which I have since found out are not suitable for use with this type of product. Transformer oil is designed to absorb 2-3 times its weight in gases and the bottles I were handling were deliberatley not sealed to reduce the chances of explosion. The histamine challenge I lasted for about 1 minute in Dec 08 but I had a really bad time metabolising sulbutimol the nebulised stuff made me ill for two days. Had a peak flow score of 2.4 but by that time I got an appointment my company had outsourced the work to a laboratory, and I was being effected by all irritants inside and outside of work and lung function was reduced by things like paint, new carpets, new mdf etc as well as work (in a refinary). At the respiratory clinic they paid no attention or made any reference to my work exposures that started these symptoms. I have avoided all chemicals as far as posssible since jan 09 on doctors advice. I suffer from burning lungs coughing up of phlem and shortness of breath when I come into contact with irritants (smoke, cigarette smoke, sulphur dioxide, bleach some perfumes, tarmac, petrol, solvents, airfreshners etc). Before working there I had no history at all of any asthma and have never smoked. I am looking for any advice on what I should do now a one respiratory consultants and a doctor have said I do not have asthma because I dont have a wheeze or a chronic cough, I just clear my throat and upper airways a lot when aggrevated I wouldn't call it a chronic cough. i have shortage of breath and pain in my lungs. I was also told I would make a recovery if I left work. I have beem chemical free for 18 months and no improvement when exposed. Any advice would be gratefully received. I went back to my GP who recommended a course of antibiotics which I refused. I do not believe I have a chest infection this is the reaction I get everyday irritants on a regular basis but I can no longer afford not to work. When I am shut up in doors or in the open air away from everything I am absolutely fine! However financially I cannot afford to stay at home any more. Any help and advice would be much appreciated. www.occupationalasthma.comThu, 15 Jul 2010 14:42:40 GMThttp://www.occupationalasthma.com/forumviewquestion.aspx?id=1082I am a mechanical engineer exposed to various chemical fumes and dust. i have been working as a engineer for 7 years and around two years ago had my first asthma attack. taking over a week in hospital to recover. ever since my asthma has been difficult to manage being off work a lot and taking many courses of steriods and various inhalers. i have been sent to have skin prick tests with the outcome i had allergy to grass dust cat and horse and mould. tests that stated my breathing was 60% of normall. then histamine test with the outcome i was the most sensitive you could be. then my doctor is still sending me to work with the belief i am probally sensitive to something at work and told me to stay away from anything that i feel affects me. where do i go from here. my asthma improves away from work and i had sleepless nights whilst at work. i am worried my health could get worse at work. i would like to claim compensation for my work causing this how can i do this without proving it is occupational? my doctor says that i am just so atopic at the moment i could be caused by anythingwww.occupationalasthma.comFri, 25 Jun 2010 00:12:52 GMThttp://www.occupationalasthma.com/forumviewquestion.aspx?id=1079Having been an asthma sufferer for most of my childhood and now, in my later years, I notice that many household sprays and air-fresheners; e.g. those made by Airwick, Ambi Pur, Glade etc, can make life very unpleasant. I feel that much of the increase in childhood asthma is caused by the introduction of these agents into the home. Has any one carried out a study on the usage and over usage of these chemical sprays and their effect on asthmatic children and adults in the home environment?

November 1, 2010. We purchased a young blue crowned conure. 1 week later I developed laryngitis, which turned into a cough. I have had this productive cough ever since. I have never smoked and we only have one bird (I had a macaw for 18 yrs, it passed away 4 yrs ago). My chest xray, ctscan and pulmonary function tests are all normal. My parents took the conure for 2 months as a test to see if the bird is the cause (my pulmonary doctor thinks it is, but I tested negative to the skin prick test for budgies and chickens). During the 2 months there was improvement but not long lasting, the cough always came back. I have the bird back now, within 24 hrs of bringing the bird home, I have come down with a fever. The fever is not accompanied with shortness of breath and is only at night, for 2 nights in a row. I have always been very healthy. Could I be having an allergic response to my bird? Thank you!!!

His symptoms worsened from 2002 and he was removed from the plant in 2005 after 6 weeks of pefr monitoring in and out of work. I was not convinced that his PEFR during chemical exposure were much different in and out of work although he did appear to have more diurnal variability on work days around 10% of predicted his oasys score was 2.41. I wonder if he has a dgree of worsening of asthma due to exposure rather than true OA. strong family Hx of asthma and had previously been investigated by PEFR in the 90's and again in 1998 with no confirmed diagnisis but always a low PEFR ~450 (Pred 540 at that time) and occasional improvement with ventolin. He also did 2 weeks of pefr at work but in a different part of the plant where he was not exposed to hexamine prior to the above monitoring. His oasys score was surprisingly 3.0 but he only had one day off so I assume this is a confounding factor?www.occupationalasthma.comMon, 12 Oct 2009 09:22:29 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=392#comments101 records from occupational asthmatics and 36 records from non-occupational asthmatics were used to assess the Oasys score. Sensitivity was 81.8% for records of 4 weeks' duration and 70% for those of 2 weeks' duration (specificity 93.8 and 82.4% respectively). The sensitivity fell to 56.7% if there were only 2 consecutive workdays in each work period. Although best at 8 readings per day, sensitivity and specificity were acceptable with four daily readings (82.4 and 87%). The effect of defining a record as being of adequate quality if it was of =2.5 weeks' duration, with =4 readings per day and =3 consecutive workdays in each work period, was tested in records not used in the initial data reduction process.

I would like to know if sodium hypochloride which they use in our local swimming pool is a trigger for an attack. History - We had 6 weeks of my daughter being ill with asthma before Christmas so we stopped the lessons she was having and re-started them a fortnight ago. Last week after her lesson she become ill with asthma. The swimming lessons are the only consistent thing in all of that time as she was not at Pre-school and has now started school which is a new environment. Would you please take the time to answer my problem as I am in a dilemna as to whether we should stop the lessons.

The first assessment was done after substantial reduction in exposure having not worn latex gloves for months or years, but remained exposed to latex in the air from coworkers. At follow-up the reduced exposure group were exposed to less than 20 latex gloves used in their department/week or only sterile low allergen gloves were used. There were no air measurements made. None of the comparisons tested differences between the reduced exposure and no exposure groups. There are no redsults for the initial latex IgE levels, or changes at follow-up. The reduced exposure group took a mean 112 minutes of exposure in the initial challenge, vs 60 mins for the complete removal group, who were initially and at follow-up on more treatment, suggesting that the reduced exposure group were less severe at presentation. It is not safe to conclude from this paper that reduced exposure to latex is as good as no exposure.www.occupationalasthma.comWed, 14 Jan 2009 22:05:17 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=4575#commentslength of symptomatic exposure most important factor in prognosiswww.occupationalasthma.comSun, 11 Jan 2009 12:29:01 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=4563#commentsEvidence Table: www.occupationalasthma.comSat, 10 Jan 2009 18:44:46 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=4552#commentsDespite a lot of work, the case for or against occupational asthma was not made as the deciding test was an analysis of erial pef by 2 experts based on a lack of changes or diurnal variation on work and rest days without any other reported analysis.

The main consensus statements are as follows 1. In all individuals with new-onset or worsening asthma, take a history to screen for WRA (OA and WEA). Then confirm the diagnosis of asthma and investigate to determine whether the patient has WRA, performing these tests, whenever possible, prior to advising the patient to change jobs. 2. In all individuals with suspected WRA, obtain a history of job duties, exposures,industry, use of protective devices/equipment, nd the presence of respiratory disease in coworkers, and consult material safety data sheets (MSDSs), which list many recognized hazardous agents. Document the onset and timing of symptoms, medication use, and lung function, and their temporal relationship to periods at and away from work. 3. In individuals who have asthma not caused by work but that subsequently worsens while working, consider the diagnosis of WEA, which is usually based on changes in symptoms, medication use, and/or lung function temporally related to work. 4. In individuals with suspected sensitizerinduced OA, in addition to carefully documenting the occupational history, perform additional objective tests when feasible (eg, serial peak flow recordings, serial methacholine challenges, immunologic assessments, induced sputum testing, and SICs) to improve the diagnostic probability. 5. In individuals with suspected WRA who are currently working at the job in question, record serial measurements of peak flow as part of the diagnostic evaluation and ask the patient to record these optimally a minimum of four times daily, for at least 2 weeks at work and 2 weeks off work. 6. In individuals with suspected sensitizerinduced OA, working at the job in question, perform a methacholine challenge test or obtain comparable measurements of nonspecific airway responsiveness during a working period, and repeat it during a period (optimally, at least 2 weeks) away from the work exposure to identify work-related changes. 7. In individuals with suspected sensitizerinduced OA, perform immunologic tests (skin prick testing or in vitro specific IgE assays) to identify sensitization to specific work allergens when these tests are technically reliable and available. 8. In individuals with suspected sensitizerinduced OA, conducting an SIC (where available) is suggested when the diagnosis or causative agent remains equivocal; however, this testing should only be performed in specialized facilities, with medical supervision throughout the testing. 9. For all individuals with WRA, attempt better control of exposures. Remove patients with sensitizer-induced OA from further exposure to the causative agent in addition to providing other asthma management. 10. In individuals with irritant-induced asthma or WEA, the panel advises optimizing asthma treatment and reducing the exposure to relevant workplace triggers. If not successful, change to a workplace with fewer triggers is suggested in order to control asthma. 11. For workers who are potentially exposed to sensitizers or uncontrolled levels of irritants, the panel advises primary prevention through the control of exposures (eg, elimination, substitution, process modification, respirator use, and engineering control). 12. An individual diagnosis of OA represents a potential sentinel health event: * Evaluate the workplace to identify and prevent other cases of OA in the same setting; and * For work environments with potential exposure to sensitizers, the Panel advises secondary preventive measures including medical surveillance using tools such as questionnaires, spirometry,and, where available, immunologic tests.www.occupationalasthma.comSat, 18 Oct 2008 19:07:20 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=4492#commentsAlso a positive immediate reaction to potassium dichromate at 10mg/ml. ? specific at this concentrationwww.occupationalasthma.comThu, 16 Oct 2008 18:35:03 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=4487#commentsEvidence Table:www.occupationalasthma.comThu, 09 Oct 2008 09:58:25 GMThttp://www.occupationalasthma.com/forumviewquestion.aspx?id=869i have been using cyanacrylate glues for 2 years making lampshades. i have never ever suffered with asthma and after a couple of months working with the glue i started being ill. my doctor gave me an inhaler and when the illness got worse he referred me to a respiratory consultant. the consultant now wants me to have second opinion as he thinks it is occupational asthma and wants to prove it. am i able to make a claim for compensation from my employer? i have recently left that job www.occupationalasthma.comFri, 26 Sep 2008 23:06:00 GMThttp://www.occupationalasthma.com/occupational_asthma_pageview.aspx?id=85#commentshow do you set the reference values PEF & FEV1? how do you find what values are for you? please help jimbopilwww.occupationalasthma.comWed, 24 Sep 2008 00:22:44 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=4238#commentsMay I have more information regarding botled waterwww.occupationalasthma.comMon, 08 Sep 2008 01:37:08 GMThttp://www.occupationalasthma.com/occupational_asthma_viewreference.aspx?id=1208#commentsPlease send me emails about new plantation methods to rosington@gmail.com. or call to my phone number +94722306831www.occupationalasthma.comSun, 07 Sep 2008 10:33:29 GMThttp://www.occupationalasthma.com/forumviewquestion.aspx?id=860Once a year I go to Forida to visit my son.

Occupational asthma (OA) was diagnosed when the challenge tests were positive, unrelated to the presence or absence of a latent interval or pre-existing asthma (including some with workplace challenge tests for both WEA and OA).There were 15 with work-exerbated asthma exposed to flour (1), latex (1), isocyanates (3), glutaraldhyde (1), triethanolamine (1) and 8 unidentified. 4 0f the 19 with occupational asthma had no identified agent. Medication was kept the same throught peak flow monitoring (2 weeks at work and 2 weeks away from work)but long acting beta agonists were stopped for specific and methacholine challenges. PEF variability was expressed as the diurnal PEF variation and calculated using thr highest amplitude percentage and the mean amplitude percentage for the work and off work days. A paired t-test was used to compare work against off work and a students t-test to compare WEA with OA. The number of days wehere diurnal variation was over 20% was also analysed as well as Oasys scores and a qualitative approach (visual analysis of PEF graphs by 5 experts). Results: Occupational asthmatics had a slightly longer duration of exposure, and both groups had increased symptoms at work. Both showed an increased diurnal variability of PEF at work compared with off work, but the OA's were slightly higher at work. A greater percentage of the occupational asthmatics showed >20% diurnal variation on more work days than the WEA's. 6 records from each group (OA and WEA) had Oasys scores >2.5. Agreement between expert vsual analysis was low (Cohen K 0.27-0.7). The discussion indicates that peak flows could not entirely differentiate between OA and WEA. The low number of Oasys positives could have been caused by the continuation of long acting beta agonists which were stopped for challenges (not written in the paper). The authors indicate that a stepwise approach to diagnosing OA is required and that although PEFs are an asset to confirming work-related problems, specific challenges are still the best method.www.occupationalasthma.comWed, 16 Jul 2008 15:35:40 GMT
