In the concrete discussions the Occupational Diseases Committee will include the above issues cheap 100 mg thorazine amex. With regard to cases decided without applying the list we refer to chapter 1 of this guide cheap 100 mg thorazine free shipping. Examples of decisions based on the list Example 1: Recognition of chronic obstructive lung disease under E order genuine thorazine line. He was massively exposed to dust during chimney sweeping, and he did not use respiratory protection to begin with. A lung function examination established reduced lung function and he was diagnosed with chronic obstructive lung disease. In the performance of his work the chimney sweep was massively exposed to dust for many years, and he was diagnosed with chronic obstructive lung disease. The tobacco consumption of no more than 1 package year was very moderate and did not contribute to the disease. The work was performed in small rooms inside the ships and generated a great deal of smoke. In particular at the beginning of the period there was no sufficient respiratory protection, and the ventilation was poor throughout. The generation of smoke during the welding process resulted in frequent coughing attacks so that he had to go outside to get some fresh air. Over a number of years he developed signs of chronic bronchitis med frequent coughing and sputum expectoration and towards the end of the period developed respiratory passage problems in the form of breathing problems. He was diagnosed with chronic obstructive lung disease in a lung examination performed in a clinic of occupational medicine. In the performance of his work the welder was massively exposed to unspecific welding smoke in a room with poor ventilation and insufficient respiratory protection for a significant number of years, and there is good time correlation between the exposure to welding smoke and the disease. A scientific reference document on behalf of The Danish Working Environment Research Fund (www. Item on the list The disease asthma is included on the list of occupational diseases (Group E, item 8): Disease Exposure E. Asthma Dust or vapours from (allergic and non-allergic) (a) Plants or plant products (b) Animals or animal products (c) Enzymes, dyes, persulphate salts, synthetic resin or medicaments and precursors thereof (d) Isocyanates and certain anhydrides in epoxy resins (e) Chromium and some chromium compounds (f) Cobalt (g)Aluminium (h)Hard metal (i) Nickel 3. The diagnosis of asthma bronchiale, which is equivalent to asthma, is also covered by the list. This diagnosis is used by some doctors to describe a condition of diffuse respiratory symptoms, in particular in young children, but usually has nothing to do with actual asthma. Therefore the condition is not covered by the list, except where there is medical documentation that it is a case of asthma. In order make the diagnosis of asthma, the following requirements must be met Relevant subjective complaints (symptoms) and Clinical, objective degeneration Asthma is a very prevalent disease in the population, and only a minor proportion is caused by exposure to harmful substances in the workplace. These breathing problems are caused by a periodic obstruction of the respiratory passages (the small bronchias). There are many factors that contribute to the development of asthma and many that can provoke attacks. Asthma is a condition where the small bronchias are inflamed/irritated, either as a consequence of a previous infection (for instance with bacteria) or a previous inflammatory condition (without bacteria). Inflammation/irritation of the small bronchias makes the respiratory passages more sensitive to specific external irritants (trigger factors), which cause the respiratory passages to contract and thereby reduce the airflow and cause breathing problems in the person in question. Asthma is furthermore characterised by the lung function being normal or almost normal between the attacks or normal as a result of bronchia-extending medical treatment. As opposed to chronic bronchitis the increased resistance in the respiratory passages can be affected by bronchia-extending medicine such as Beta2 agonist spray, Bricanyl or Ventoline, or treatment with adrenal cortex hormones. In many cases the attacks will be triggered by irritants in the air, such as tobacco smoke, fog, or dust from work processes or other exposures from the environment. Symptoms Breathing problems (hard to empty the lungs of air) Shortness of breath or a wheezing sound in the chest Perhaps coughing, a pressing sensation on the chest, and hoarseness Clinical examinations and findings The medical examinations must describe a symptom picture that makes likely an asthma diagnosis. Objective signs of asthma Establishing allergic asthma (allergy) Allergic asthma can be established in one of the following tests: a. Specific bronchial provocation tests with relevant allergens, performed by specialised departments of occupational or lung medicine can also be used for the assessment of the question of recognition. The National Board of Industrial Injuries would not directly recommend this type of tests as they rarely lead to any aggravation of the disease. If there is documentation of asthma attacks in connection with the work as well as allergy to an exposure in the workplace included on the list of occupational diseases, asthma qualifies for recognition on the basis of the list. Establishing non-allergic asthma For non-allergic asthma it is harder to establish any causation with exposure to substances in the working environment. Therefore there are stricter requirements to the medical documentation of any correlation between the asthma attacks and the exposure at work. In this connection it is vital to know if the injured person had asthma before the beginning of the work- related exposure and to obtain information on the preceding development of the disease. In cases of severe and long-lasting cases of preceding asthma or asthma with substantial, competitive private allergens or established irritants this may have the effect that the claim is turned down completely or that deductions are made from the compensation. Repeated measurements with a peak flow meter will often show if the injured persons lung function becomes reduced in connection with work and improves during the weekends, for instance, or in holidays, or the other way round. Isocyanates are a generic term for a group of chemical substances which are much used in industry today, for instance in the production of lacquers. Isocyanates are released in great quantities when materials coated with isocyanates are heated to 150- 200 degrees centigrade. This is the case, for instance, with lacquered car parts repaired/welded in garages or electronic parts that are repaired. Isocyanates are also released by oxidation of chlorine-containing degreasing agents in the metal industry; by galvanization and steel hardening and by gold and silver work. Also, isocyanates are often used in products composed of two components which, when mixed, react with each other during the production of plastic. Steel contains chromium, and therefore welding and similar work on steel materials will be included. Cobalt has for centuries been used to give glass, glazing and ceramics an intense blue colour. The core of the material is the element wolfram tungsten, which through a special process gets chemically tied with coal. The above list of typical occupational groups is merely a guiding list and it is not exhaustive with regard to persons who may suffer relevant exposure to the substances in question. Other occupations will also be covered by the list to the extent that it is the same exposure as set out above. Exposure to welding smoke Exposure to welding smoke is not necessarily covered by the list item regarding asthma.

A prerequisite for the establishment of methodology for non-invasive hormone monitoring is the biological validation of the analytical method. As this validation is impossible to perform in the highly endangered Iberian lynx, the Eurasian lynx was suggested as a model for the establishment of hormone monitoring in captive male and female lynxes. The aim of the presented study was to characterize relevant steroid hormone metabolites in captive Eurasian lynx to assist with non-invasively monitoring of male and female reproductive performance. The ultimate goal was to provide a biological validation of fecal hormone assays to be applied in the Iberian lynx captive breeding programme. The animals were kept within six enclosures (74 m ) and in one large fenced enclosure (7. Animals were housed separately and males and females were put together only for mating. Fecal samples were collected monthly throughout a two-year period and stored at 20 c within 1 h after defecation until analyses. From February to April (prospective mating season) the frequency of collection was increased to 1-2 times per week. For comparative assessment of hormone metabolites, fecal samples from captive Iberian lynxes were provided from the Iberian Lynx captive Breeding center, El Acebuche, in Doana national Park (Vargas et al. After centrifugation (15 min at 1200 g) the supernatant was transferred into a new tube. All hormone measurements were carried out in duplicates to assess the coefficient of variation. Results were expressed as immunoreactive steroid metabolites in g/g of fecal wet weight. The cross-reactivitys of both antibodies and their inter- and intra-assays as coeffcients were as described before (Dehnhard et al. Ra d I o m e t a b o l I s m s t u d y To identify relevant progesterone metabolites we carried out a radiometabolism study. Following the radiolabelled injection, all excreted fecal samples were separately collected from the enclosures immediately after defecation during a 4-day period, placed in a plastic bag and stored at -20 c. Aliquots of each sample were extracted for gestagen determination and for radioactivity counting. All radioactive counting was conducted in a Perkin Elmer MicroBeta Trilux counter (Perkin Elmer, Germany). Metabolites were separated with a methanol:water mixture (78:22) at a fow rate of 1 ml/min. Metabolites were separated with an acetonitril: water mixture (43:57) at a fow rate of 1 ml/min. According to the manufacturer the functional sensitivity for the T assay on this system is 0. A test for parallelism was performed for feces from both the Eurasian and the Iberian lynx. Ra d I o m e t a b o l I s m s t u d y The testosterone radiometabolism study was performed with a solution (0. Sedation and sample collection was performed as described for females (see above). Aliquots of each sample were extracted for testosterone determination and radioactivity counting. To prove whether testosterone or its metabolites were conjugated to glucuronides or sulfates, the fecal extract was also subjected to enzyme hydrolysis and solvolysis (Jewgenow et al. A linear gradient was generated at a fow rate of 1 ml per min: 011 min, 60% to 75% methanol; 11-20 min, 75%; 20-25 min, 75% to 100% methanol. The statistical procedures were performed with the software programme Instat Version 3 (Graphpad Software Inc.

There is a tendency towards higher progestagen and estrogen metabolite concentrations during pregnancy. However, no distinct differences between profles from pregnant (a) and pseudo- pregnant (b) females were obtained. As shown for pregnant and pseudopregnant females, a distinct estrogen peak was absent at mating time. Both steroid metabolites showed a post-partum increase with no difference between the pregnant (a) and pseudo-pregnant (b) females. The results from the Eurasian lynx revealed that the measurement of fecal progesterone metabolites led to irregular patterns, which were different from expected profles derived from data of other felid species (Brown et al. Thus, fecal estrogen and progesterone metabolites were ineffective for estrus and pregnancy diagnosis in Eurasian and Iberian lynx (see also Pelican et al. Therefore a radiometabolism study was necessary to investigate whether our enzyme immunoassay could detect the relevant metabolites refecting the biologically active hormones. This involved the characterisation of immunoreactive metabolites during and after pregnancy, the determination of blood serum hormones (Jewgenow et al. Because of the limited sample size for each month, testosterone metabolite concentrations were combined every two months before, during and after breeding season, and every three months during the non-breeding period. In all four males, a similar pattern of fecal testosterone metabolite concentration were obtained with highest concentrations during the breeding season (March-April) and lowest values in January/ February.

For the development of techniques for fecal steroid analysis, experiments on the metabolism of radiolabelled steroids have provided a valuable insight into the metabolism and the excretion of hormone metabolites via faeces and urine. When passing through the non-polar (reversed phase) column, the metabolites are retained and separated based on differences in their polarity. The extract of female lynx faeces is composed of four major polar radiolabelled gestagen metabolites detectable in fractions 6-8, 10, 12-13, and 1617. Only minor amounts of radiolabelled progesterone metabolites were detectable at positions of unpolar substances corresponding 6 6 5 * m a l e 1 (15y) 5 m a l e 3 (4y) 4 4 3 3 2 * 2 1 1 0 0 Jan-Feb maR. This suggests that the circulating hormone itself is merely present in minor quantities in feces. In contrast, the radioactivity within a fraction directly refects its quantitative amount and, thus, the composition of metabolites even if their detailed chemical structure remains unknown.
