Asmapro available on CD-rom :This Asmanet Web service is under construction, with a CD for off-line usage. Medline abstracts have been added to the CD off-line version in order to have them without an Internet web access. The service is available for Mac & PC in French and in English. The AsthmaPro version uses Metacard and is very handy thanks to its excellent integrated search engine - the HTML version uses Google as an off-shore search engine, which implies then a web online access - april2003); CD can be obtained free of charge for eligible people (limited stocks); just send your request and professionnal data to Mr L. Mousseau (Phadia). You may also write to Croisix who shall forward your request whenever eligible. |

Incidence: low in comparison to the widespread usage of these resins. The mechanism resembles an irritative and toxic type of eczema except for the absence of lesions. Smoking is an established aggravating factor. No immunological mechanism has been demonstrated. |
The acrylate family can be divided into resins and glues. Methyl methacrylate is the monomer for acrylic resin polymers. Inhalation of cyanoacrylate glues may provoke an asthmatic attack. Hardening agents such as polyfunctional aziridine (PFA) may also give rise to asthma. Ventilation (in particular by increasing the downdraft air volume) protects the subjects at risk (e.g. during application of artificial fingernails). Ventilation systems reduce the concentration of methyl methacrylate but not the concentration of acrylic resin dusts. |
Asthma is associated with serious ENT symptoms: rhinitis, sinusitis, laryngitis and conjunctivitis. Urticaria (glues) and/or recurrent eczema may occur. Recurrent eczema may be observed. Headache, sensations of inebriation and digestive problems have been described. |

Bronchial provocation test (in Hospital) and monitoring of respiratory parameters in the work place are decisive arguments. Skin tests can be performed and specific IgE looked for, but these are rarely positive. There is no cross reactivity between different acrylates which can be demonstrated by bronchial provocation tests. Levels of eosinophils in induced sputum are increased following occupational exposure or tests performed using cyanoacrylate.. |

Symptom |
Incidence: asthma is much less common than dermatitis and nasal complaints caused by chromates, amongst these workers. Sensitization can take from several days to several years to develop. Atopic predisposition has yet to be established. IgE-dependent mechanism, however skin tests with unstable conjugates are often negative. Chromium salts are very caustic. Subjects suffering from alveolitis caused by chromium's toxicity have been noted as well as RADS (Reactive airways dysfunction syndrome or asthma caused by irritants – Brooks syndrome).. |
Chrome plating, polishing, chrome yellow paint, aluminium production, stainless steel welding and production of chromium metal. The cement used by bricklayers can cause asthma. |
Asthma attacks at and/or after work with cough and tight chest, sometimes severe and developing into permanent dyspenoea. Hemorrhagic rhinitis and nasal pain. Eruption of facial oedema and urticaria, contact eczema. ENT cancers have also been reported. |

Skin prick test: 0.1, 1, 5, 10mg/ml Cr2(SO4)3. Immunological dosage: RAST with Cr2(SO4)3 coupled to HSA . Bronchial provocation tests (in Hospital) are sometimes performed with potassium bichromate. The bichromate is used at 0.3% over 60 seconds. In addition to the recognized risks associated with BPT, problems with arterial tension may also occur. |

Incidence: low as few people are involved in this precise type of work. Subjects are not always atopic. IgE-dependent mechanism. Specific forms of IgE have been demonstrated to be present at significant levels, in particular for ovomucoid and ovalbumin. |
Spraying and brushing of foodstuffs with solutions containing egg yolk. Manufacture of egg powder. An American study performed in bakers and confectioners and published in 2001 demonstrated that it is possible to measure protein levels (ovalbumin, the ovomucoid fraction and lysozyme) in the workplace. The highest levels were found in those parts of the factory where the eggs are broken (breaking room). |
Asthma, cough and breathing difficulties, initially occurring at the start and at the end of the working day. Risk of anaphylactic reactions occurring after ingestion of egg products , similarly after occupational exposure, an “egg-egg” syndrome may be observed... |

Incidence: increasing - probably due to the proportion of atopic subjects working in these areas. 50% of affected subjects are atopic. IgE-dependent mechanism although there may also be an interference with arachidonic acid metabolism. The limits recommended for occupational exposure to sulphite and metabisulphite is 5mg/m3. There are also limits set for the food industry. The gravity of the problem lies in the constant risk of triggering an asthmatic attack through the inadvertent consumption of the allergen. In a factory producing persulphates, it was demonstrated that the drop in bronchial flow was greater in those subjects who has a positive skin prick test. |
The role of sulphites as occupational inhaled allergens is less well known and its description more recent than that of preservatives in food allergy. In contrast, persulphates are widely used as bleaching agents. |
Asthma and rhinitis are frequently associated with urticaria, eczema, flush and hypotension. Ingestion of sulphites may cause anaphylactic shock in sensitized subjects. |

Incidence: low, however all subjects who are exposed to nickel and develop asthma symptoms must be investigated because the disease is severe and can develop into chronic bronchopathy. IgE-dependent mechanism. Atopy does not appear to play an important role. A positive nickel patch test has no predictive value to judge the likelihood of developing asthma. Skin tests producing an immediate result are not always reliable and may be dangerous. |

Incidence: originally very high (>50% of exposed subjects) when first reported. With appropriate precautions in the work place this figure is now 10%. Most sufferers are atopic. The sensitization period takes from 15 days to several years. IgE-dependent mechanism, however platinum salts will cause release of histamine in vitro (cutaneous basophils and mast cells behave differently). The immunological assay of specific IgE molecules remains the most usual area of research: but conflicting results have been obtained. Skin tests with palladium have proved positive in dentistry; palladium being contained in dental alloys. Cross-reactivity between nickel and palladium frequently occurs. |
The first reported cases involved subjects who worked in photographic studios. Precious metals industry: platinum refining. Metals of the platinum group, the so called “precious metals” include ruthenium, palladium, osmium and irridium |
Asthma is sometimes preceded by eczema, urticaria and angioneurotic oedema. Rhinitis may be the only symptom for a long time or it may be immediately associated with asthma. It occurs at work and may continue during the night with or without a spasmodic cough. Respiratory parameters and bronchial hyperreactivity only partially regain their normal values after work has stopped. Changes in the workstation of the subject to a less exposed area does not result in an improvement in airway parameters. |

Skin prick test: using large dilutions of ammonium hexachloroplatinate from 10-9 to 10-3. Bronchial provocation test (in hospital) is very reliable but difficult to conduct successfully. The response is almost always an immediate reaction. Measurement of specific IgE : phadezym (Germany). Skin tests with Pd(NH3)4Cl2 are positive where there is an IgE-dependent mechanism. In the case of eczemas, patch tests are positive for the causative metal. |

Employees working in intensive culture greenhouses (especially jasmine). Agricultural research workers (especially sunflowers) and all persons whose job brings them into contact with plants: florists (tulips) and the esparto industry (Stipa tenacissima),. The allergens are the pollens but the leaves, bulbs and seeds may also be involved. Work in greenhouses can increase the risk as compared with work in the open air. Pollens of the cruciferous family are also the cause of sensitisations in cultivation areas. For example, Diplotaxis erucoides or wall rocket, may cause asthma in wine-growers. Pollination of this crucifera plant occurs between March and April in between the vines. Other crucifera plants may also be implicated in different agricultural practices such as Brassica oleifera in rapeseed cultivation. Farmers may also become sensitised to the mould Aspergillus Niger if it contaminates the crops. |
In general, pollen induced asthma is typically associated with episodes of coryza. Symptoms occur due to the specific pollen present in the work place outside of the natural pollen season. Asthma can be caused by preparation of bouquets of dried flowers, cleaning leaves (ficus) or pruning (stathiphyllum). Gardeners may experience asthma attacks whilst mowing lawns (aerosol of grass pollen allergens). The phoenix plant can cause contact urticaria and asthma. Urticaria of the forearms is on the increase. In 2001, a case of Hypersensitivity pneumonitis and extrinsic allergic alveolitis was described following contact with Stipa tenacissima (Esparto grass). |
