In special cases late asthma qualifies for recognition if there are attacks up to 16 hours after the exposure in the workplace buy calan 80mg free shipping. However order calan overnight, in such cases it has to be documented that similar attacks do not occur at the same hour of the day during weekends or holidays (i buy calan paypal. On the other hand, there is no requirement for the exposure to have a certain duration or severity. This is because asthma is in some cases triggered after a short while and in connection with even limited exposures. Examples of pre-existing and competitive diseases/factors Like most other diseases, asthma can develop or become aggravated as a consequence of other diseases or factors not connected with work. Therefore the National Board of Industrial Injuries will make a concrete assessment of whether any disclosed competitive factors are of a nature and scope that may give grounds for turning down the disease entirely or whether, if the claim is recognised, there are grounds for making a deduction in the compensation. Examples of possible competitive factors which may affect the onset or the course of the disease: Tobacco smoking Private allergy (for instance to house-dust mites or pollen) Genetic disposition to allergy Medicine consumption Tobacco smoking cannot be deemed to be the primary cause of asthma. But there may be consistence in the symptomatic picture for asthma and diseases that are primarily caused by tobacco smoking. Therefore, in some cases smoking may have the effect that a reduction is made in the compensation payment. Managing claims without applying the list Only asthma is covered by group E, item 8 of the list. Furthermore, as stated in the list of occupational diseases, there must have been exposures meeting the recognition requirements. Asthma not covered by the list will in special cases qualify for recognition after submission of the claim to the Occupational Diseases Committee. Examples of cases that may qualify for recognition not based on the list: Asthma caused by working for a long time with low-molecular irritants (factory worker who operated a wall paper printing machine producing using acrylic foam) Asthma bronchiale caused by several years of cleaning of smoke ovens, using alkaline foam detergents and chlorinated substances etc. Shortly after she started work she would catch a cold very often and had sinusitis and problems when staying indoors. In the course of her employment she developed a persistent cough and tended to have breathing problems and eventually a specialist of pulmonary diseases diagnosed her with asthma. A building report described rather substantial deficiencies in the indoor air quality in her workplace, in the form of humidity damage, and according to the report there was visible mould formation. The day-care worker developed asthma after working in humidity damaged rooms with visible mould attack. There is a good time and causal relationship between the development of asthma and exposure to harmful plants (mould fungus) in the workplace. After 10 years he became responsible for the production and the machines, the administrative work being performed in an office in affiliation with the packing department. In the course of the last year he developed increasing respiratory passage problems with coughing, periodic attacks of wheezing, and breathing problems. In connection with being transferred to a different department he experienced a considerable improvement in his symptoms. He was diagnosed with asthma and tests showed that he was allergic to certain types of fish. The allergies were relevant in relation to the exposures to fish vapour in the workplace, and peak flow measurements showed aggravation when we was there. The fishing industry worker developed asthma as a consequence of work on premises where there was fish vapour. He was furthermore diagnosed with allergy towards certain types of fish which were also part of the production in the workplace. There is a good causal relationship between the development of asthma and the exposures in the workplace to vapour from animals/animal products. Towards the end of the period he developed symptoms of asthma in the form of red and irrigated eyes as well as breathing problems which developed when he was in the workplace. The symptoms disappeared after a long presence from work and completely disappeared after cessation of work. For a considerable number of years he suffered significant exposure to dust or vapour from animals, animal products and plant products. There is good correlation between the exposure from dust and vapours in connection with cleaning work and the symptoms, which disappeared temporarily after a long absence from work and completely when he stopped doing the work in question. Furthermore she had to close and move bags full of work clothes from the production. The bags were often overfilled and when the clothes were transferred to another bag, it generated dust. Already after a couple of years work she developed symptoms in the form of shortness of breath and was later diagnosed with allergy to various enzymes. The cleaner developed asthma as a consequence of exposure to dust from enzymes in the workplace. She tested allergic to enzymes and the symptoms of the disease developed in close time correlation with her work. In connection with gold and silver work the materials were warmed up, which released isocyanates from the materials. After 15 years the goldsmith experienced episodes of breathing problems, coughing and wheezing. For a considerable number of years the goldsmith suffered considerable exposure to isocyanates when working gold and silver into jewellery. There is good correlation between the exposure from isocyanates and the symptoms, which disappeared during holidays and completely disappeared in connection with cessation of work. After 4 years he began to work in the spray paint department and subsequently developed coughing and wheezing in connection with physical exertion. He stopped smoking, but the symptoms continued and also interfered with his sleep during the night. For a considerable period of time the auto spray painter suffered substantial exposure to isocyanates in connection with spray painting of cars. There is a good time and causal relationship between the exposures in the workplace, where he was in contact with isocyanates in connection with painting of cars, and the asthma symptoms, which likewise receded after he began to use better respiratory protection. He was inside the pig stables for most of the work day and was in close contact with the animals in connection with mucking out, piglet births, etc. Furthermore there was a constant reek of pigs in the stable, and the exhaust equipment was inadequate. It appeared from the medical information that he had been suffering from asthma since childhood and that he had experienced continuous and periodic, very severe attacks of asthma, right up to the beginning of his work in the pig stable. There was no record of any change in the attack patterns, and he had just as frequent and just as severe attacks during weekends and holidays as in connection with work. He furthermore suffered relevant exposure to pigs while working in a pig stable for 6 months. However, before starting in this job he had asthma attacks for a significant number of years and previously tested allergic to many different sources, including pigs and dogs. He is in contact with pigs in his free time and also has a dog himself, even though he is allergic to such animals.

Pemphigus has three variants categorized by the presence/absence of intraepithelial blisters and erosions of the skin and variable involvement of the mucous membranes. The diagnosis of pemphigus and bullous pemphigoid is based on the clinical picture and confirmed by specific immunopathological findings. In general, the natural history of pemphigus is characterized by constant progression with a high mortality risk; the prognosis of bullous pemphigoid is more favorable. Treatment consists of systemic corticosteroids, corticosteroid-sparing agents, and specific immunobiologic agents. Bullous pemphigoid tends to be more responsive to treatment and may also respond to topical agents as well as anti- inflammatory drugs.
