The medical diagnosis is made against the background of a combination of The injured persons subjective complaints (symptoms) A clinical purchase diclofenac 100mg visa arthritis in back neck, objective examination Symptoms Chronic (daily) pain of the neck and shoulder region Muscle tenderness of the neck and shoulder girdle (see figure below) Any aggravation of pain in connection with load on the region Any restricted motion In order for the disease to be covered by the list order diclofenac 100 mg fast delivery arthritis in back surgery, there needs to be chronic (daily) pain 50 mg diclofenac otc rheumatoid arthritis in lungs. Indication of palpation tenderness in 12 areas of the neck and shoulder girdle (6 on each side) purchase diclofenac 50 mg on-line arthritis back stenosis, stating in a form, on a scale from 1 to 4, the pain in connection with palpation: 1 = no tenderness 2 = slight tenderness 3 = moderate tenderness 4 = considerable tenderness 2. Indication of the number of tender areas (out of the 12 areas) Before the diagnosis of cervicobrachial syndrome (chronic neck and shoulder pain) can be made, there must be moderate to considerable tenderness of several of the 12 muscle areas of the neck and shoulder girdle as well as moderate to considerable distribution of tenderness to several of the 12 muscle areas 205 The tenderness may be unevenly distributed on the two sides if there is good correlation between the uneven distribution and the load. It is the combination of the severity of the pain and the distribution of pain/tenderness which, together with the relevant exposures at work and the duration of the exposure, makes it possible to make the diagnosis of work-related, chronic neck and shoulder pain. Neck and shoulder pain with no or slight tenderness (rated 1 or 2) limited distribution of moderate to considerable tenderness (rated 3 or 4) to a few muscular areas does not meet the diagnostic requirements to the disease cervicobrachial syndrome (chronic neck and shoulder pain). In addition to palpation tenderness there may be restricted motion of neck and shoulder and/or increased muscular consistency. Restricted motion or increased muscular consistency is not a diagnostic requirement, however. The work may have involved different work functions, and thus a certain job variety, in the course of the working day. If different functions were carried out in the course of the working day, an assessment will be made, for each function, of the concrete load on the neck and shoulder region. The duration of the various types of loads usually needs to be equivalent to at least half of the working day (3-4 hours). To this could be added two other functions without quickly repeated movements of shoulders/upper arms, lasting in total a little less than half of the working day and not meeting the exposure requirements. In this case there is alternation between four different work functions in the course of the working day, two of these functions meeting the relevant exposure requirements. As these two functions at the same time stretch over more than half of the working day, the claim will qualify for recognition on the basis of the list. The time requirements There must have been a load on the neck and shoulder for a considerable period of time. This usually means that neck and shoulder loading work must have been performed a. The total duration requirement in terms of years cannot be reduced to less than 6 years. Particular neck and shoulder exposures that may contribute to a reduction in the time requirement: Extremely quickly repeated movements of shoulders/upper arms Long-lasting bending of the neck Long-lasting, static load on the neck and shoulder girdle Strenuous movements of the shoulder/upper arm A very prolonged, daily exposure (more than 8 hours per day) Extremely quick movements of the shoulder/upper arm usually means at least 25-30 movements of the shoulder/upper arm per minute, or more. Long-lasting and considerable bending of the neck for large parts of the working day, without any chances of restitution (rest) and straightening of the muscles of the neck, may reduce the requirements to the total duration of the exposure, but not to less than 6 years. Besides, a reduction in the time requirement to not less than 6 years will depend on a concrete assessment of the extent and scope of the special neck and shoulder exposures. Other load requirements Quickly repeated movements of the shoulder/upper arm In order for the work to be characterised as relevant neck and shoulder loading work within the meaning of the list, there need to have always been quickly repeated movements of the shoulder/upper arm, of a certain frequency/intensity, for at least half of a normal working day (3-4 hours per day). Movements of the shoulder/upper arm are movements of the shoulder joint and/or the upper arm. This number may be reduced, but not to less than 10 movements per minute, if the work was characterised by special load factors. The following special load factors may contribute to reducing the requirement to the number of repeated movements per minute, but not to less than 10 movements per minute: Bending of the neck A static load on the neck and shoulder girdle Very strenuous movements of the shoulder/upper arm A very prolonged, daily load (more than 8 hours per day) A very prolonged load period (15 years or more) There is no requirement that the quickly repeated movements were made with both shoulders/upper arms. If the load was one-sided, however, it should always be consistent with clear symptoms with regard to the diagnostic criteria for chronic neck and shoulder pain on the side that suffered the relevant exposure. On the other hand, clear symptoms on both sides would not speak against recognition, even if the load was relatively one-sided. The list does not cover monotonous precision work performed close to the body and involving repeated movements of the hand, forearm and/or elbow, or any static load on the neck and shoulder girdle and/or bending of the neck without simultaneous, quickly repeated movements of shoulder/upper arm. Bending of the neck Work with bending of the neck is work that is characterised by being performed in postures where the neck is fixated in a flexed position for some time while quickly repeated movements are being made with the shoulder/upper arm. If the work was generally characterised by bending of the neck, it is possible to reduce the requirement to the number of repeated movements of the shoulder/upper arm per minute, but not to less than 10 movements per minute. Short-term or very slight bending of the neck in the course of the working day will not be characterised as relevant bending of the neck within the meaning of the list. Bending of the neck without simultaneous, quickly repeated movements of the shoulder/upper arm is not covered by the list. Static load on the neck and shoulder girdle Static load on the neck and shoulder girdle means that the work is characterised by working postures where the neck and shoulder girdle is fixated in the same posture for some time while quickly repeated work movements are being made with the shoulders/upper arms. But the work needs to have involved a certain amount of continued fixation of the neck-and- shoulder girdle musculature, in largely the same posture, for long intervals at a time. If the work generally was characterised by a static load on the neck and shoulder girdle, it is possible to reduce the requirement to the number of repeated movements of the shoulder/upper arm per minute, but not to less than 10 movements per minute. A static load on the neck and shoulder musculature without simultaneous, quickly repeated movements of the shoulder/upper arm is not covered by the list. Strenuous movements of the shoulder/upper arm If the work involved quickly repeated movements of the shoulder/upper arm in combination with a certain exertion of the shoulders/upper arms and perhaps also the neck, this might be able to reduce he requirement to the number of repeated movements per minute or the requirement to the duration of the load over time. In order for the work to be characterised as relevantly strenuous with regard to the neck and shoulder musculature, there must always have been strenuous movements of the shoulder/upper arm, but not necessarily exertion of the muscles of the neck. If the work did involve exertion of the neck musculature, however, this will also be included in the overall assessment of the load. In order for the work to be seen as characterised by strenuous movements of the shoulder/upper arm, there needs to have been exertion somewhat in excess of what would normally be required to lift and turn the arm without the influence of particular loads. This applies in particular in cases where the work is characterised by repeated movements without any simultaneous, stressful working postures for the shoulder/upper arm. Relevantly strenuous movements of the shoulder/upper arm may for instance be work that involves a lot of pushing, pulling or lifting with the application of a great deal of muscular force in the shoulder, perhaps with simultaneous twisting and turning movements of the shoulder joint (for instance in connection with deboning in a slaughterhouse). The assessment of whether the work can be regarded as strenuous in a relevant way for the neck and shoulder musculature includes the degree of using muscular force of the shoulder/upper arm and perhaps neck whether the unit offers resistance whether there are simultaneous twisting or turning movements of the shoulder joint and perhaps the neck whether the work is performed in awkward postures of shoulder/upper arm and perhaps the neck, for instance in extreme postures If the work was in general characterised by strenuous movements of the shoulder/upper arm, it will be possible to reduce the requirement to the total duration of the load, but not to less than 6 years. Strenuous movements of the shoulder/upper arm without simultaneous, quickly repeated movements of the shoulder/upper arm are not covered by the list. The pathological picture and the time correlation The assessment of the load must take into account the persons size and physiology. Furthermore there must be good time correlation between the onset of the disease and the neck and shoulder loading work. The first symptoms of the disease need to appear some time after the commencement of the neck and shoulder loading work. Depending on the scope of the load, some time is usually understood as several years. In such cases, from a medical point of view, there will be a time correlation between the work and the development of the disease, even if the first symptoms occur soon after the commencement of the neck and shoulder loading work. This also means that the disease must not have manifested itself as a chronic disease before the stressful work was commenced. On the other hand, a single, previous case of acute neck and shoulder pain with complete recovery does not in itself lead to the claim being turned down. It will be characteristic for chronic neck and shoulder pain to develop gradually in the course of a few years after the commencement of the stressful work and for the disease to be gradually aggravated with increasing pain in connection with continued exposure. It occasionally belongs to the pathological picture that the disease at some point in time is acutely aggravated. In such cases it is of no special significance whether such an acute aggravation occurs in connection with the work or in a different situation, as long as the aggravation actually occurs in a period of neck and shoulder loading work. If the acute aggravation for example occurs outside working hours, without it being an accident, the aggravation may still be referred to the neck and shoulder loading work. In cases where the injured person has ceased doing the neck and shoulder loading work, there must not have been any considerable aggravation after cessation of the exposure. Any substantial aggravation after cessation of the exposure would be in favour of finding that the neck and shoulder disease was not work-related. The medical specialist will among other things be asked to describe and assess the different work functions and the frequency and nature of the work movements. This description would include a detailed account of the concrete types of loads and their severity and duration in the course of the working day and seen over time.

Item on the list The following vibration-induced diseases of the hand and arm are included on the list of occupational diseases (group C, item 3): Disease Exposure C.

Degenerative arthritis of elbow or wrist (arthrosis primaria/other specified forms of arthrosis) Carpal tunnel syndrome: See item C. The diagnosis is made against the background of a combination of the injured persons subjective complaints (symptoms) a clinical objective examination The clinical diagnosis of white finger is in principle made in a clinical objective examination. If the clinical objective examination cannot immediately confirm the diagnosis of white fingers, an attempt can be made at documenting the disease in the ways stated below. If the attempt at provoking an attack of white fingers is not successful, the disease cannot be deemed to have been documented and the claim cannot be recognised on the basis of the list. As the attacks are triggered after exposure to cold, part of the examination can also be made by way of a simple cold provocation test where the person in question keeps his/her fingers under cold running water or inserts the finger in ice water for 5 minutes in order to provoke a white-finger attack Photo documentation. When an attack occurs, a witness confirms the white fingers by way of a photo of the person reporting the white fingers. The photo needs to show the face and hands of the person in question Certification by a doctor. An examining doctor (for example a specialist of occupational medicine) certifies that, in the examination, he or she has seen white finger attacks in the person in question with a detailed symptom description as set out below Perhaps a vascular-physiological examination. The examination is performed in a special laboratory with registration of finger blood pressure before and after finger cooling. However, if a vascular-physiological examination shows a positive white finger result, the disease is regarded as having been documented. Description of symptoms Regardless of the documentation method used, there always has to be a clear symptom description which sets out in detail which fingers and how much of the fingers may react with colour changes and a dead feeling. Furthermore there needs to be a detailed description of the delimitation and of the course of the attacks (prevalence, frequency, and duration). Work-related vibration disorders are usually reviewed by specialists of occupational health, but the documentation of attacks can also take place in other ways, see above. When the attack is subsiding, the lividness is replaced by a blue/red discolouration accompanied by a tickling sensation. Objective signs The diagnosis of white fingers is basically made in a clinical examination. Findings in a clinical examination while the person in question is having a white finger attack will be sharply delimited white fingers, involving one or more fingers on one or both hands. In a large number of cases there will be a need for the person in question to have supplementary medical examinations made: A. Assessment of wrist pulses when lifting arms and turning head sideways at the same time C. Examples of pre-existing and competitive diseases/factors Like most other diseases, white fingers 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 the nature and extent of any disclosed competitive factors 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: Familiar disposition (white fingers can be hereditary) Information of Raynauds disease of the toes Previous arm fractures Other vascular diseases of the arms Connective tissue diseases (real arthritis/rheumatoid arthritis and other autoimmune diseases) Polycytemy (a condition with abnormal increase in the number of red blood cells) Symptoms or information of any arteriosclerotic diseases, i. We cannot demand invasive examinations, but this type of examination can also be made non-invasively with surface electrodes Furthermore it may be beneficial to take a blood sample in order to rule out that substantially competitive conditions such as alcoholism, diabetes, B12 vitamin deficiency or folic acid deficiency may be the primary cause of the disease Peripheral neuropathy means injury to the distal nerves (impact on nerve ends or degeneration of nerve roots) and may occur in hands as well as feet. Peripheral means that there is damage to the ends/roots of one or more nerves with diffuse neuropathic complaints as a consequence of an impact on several big main nerves (nervus medianus, nervus ulnaris and nervus radialis) of the forearm. The disease needs to involve at least one of the three said main nerves of the forearm with consistent symptoms. Usually the disease will affect several of the mentioned three nerves (polyperipheral 136 neuropathy), but the disease can also be limited to a single nerve (monoperipheral neuropathy). The sensory nerve impulses have the effect that you for instance feel touch, pain, temperature, and pressure. This means that peripheral neuropathy may become manifest as fine motor and sensory complaints, but not necessarily both at the same time. Peripheral neuropathy can also be an accompanying disease to white fingers (Raynauds disease) and will in that case accompany the white finger attacks as opposed to an independent peripheral neuropathy, where the symptoms typically will be of a more permanent nature. The peripheral neuropathy will then in principle be regarded as a consequence of white fingers, which may qualify for recognition on the basis of the list, and therefore will not be processed as an individual disease. Cases of neuropathy in other regions than hands and fingers are not covered by this item of the list of occupational diseases. If there is peripheral neuropathy of hands as well as feet, this will furthermore be indicative of the disease having other causes than hand-arm vibrations in the workplace. For carpal tunnel syndrome, as opposed to peripheral neuropathy radiating from the medianus nerve, there will be a well-delimited pressure neuropathy at the wrist. If impingement/impact on the nervus medianus (carpal tunnel syndrome), nervus ulnaris or nervus radialis has been established, with accompanying peripheral neuropathy, it is not possible to recognise the peripheral neuropathy as a separate disease under item C. We cannot demand invasive examinations, but this type of examination can nowadays also be made non-invasively with surface electrodes. Competitive diseases/factors: Like most other diseases, peripheral neuropathy can develop or become aggravated as a consequence of other diseases or factors not connected with work. Competitive diseases/factors Like most other diseases, degenerative arthritis of the elbow or wrist can develop or become aggravated as a consequence of other diseases or factors not connected with work. Examples of possible competitive factors which may affect the onset or the course of the disease: Previous fractures of the wrist or elbow Connective tissue diseases (real arthritis/rheumatoid arthritis and other autoimmune diseases) 1. Exposure requirements for white finger and peripheral neuropathy For the diseases white fingers (Raynauds syndrome/Raynauds disease) and peripheral neuropathy of hands/fingers there must in principle have been relevant stressful work for a consecutive period of time consistent with the stresses compared with time in table 1 under item 8. A condition for recognising white fingers and peripheral neuropathy of hands/fingers is that there must have been vibration through hands and arms from hand-held tools, hand-held machines or stationary machines, the exposure happening through some kind of object. The intensity is measured by vibration acceleration, the so-called frequency-weighted acceleration, which is indicated by a 2 2 measuring unit in metres per second2 (m/s ) or decibel (dB). More specific requirements to the vibration exposure will depend on the severity of the exposure as well as the extent of the use of heavily vibrating hand tools per day and over time with reference to the form. For the purposes of making an assessment, if it is not possible to get information on the concrete acceleration level of the tool, there is a form with an indicated average level, see form 2 in paragraph 8. It should be noted that old tools usually have a higher vibration level than new tools, which are often vibration dampened. It is furthermore a prerequisite for recognition that there should be a good time correlation between the disease and the work with vibrating tools. For white fingers and peripheral neuropathy the relevant time correlation is that the first symptoms of the disease are seen some time after commencement of the stressful work of hand and arm. Depending on the extent and severity of the load, some time usually means about one year and up to several years. However, the assessment must stress whether for instance there have been extraordinarily severe, daily stresses. In such cases, from a medical point of view, there will be a time correlation between the work and the development of the disease, even if the onset of the first symptoms is a short while after commencement of the wrist-loading work. However, the disease must not have been manifest as a chronic disease before commencement of the stressful work.

Muscle Tissue Features A typical finding in polymyositis and dermatomyositis is inflammation in muscles and muscle fiber damage. The inflammation is characterized by the presence of inflam- matory cells such as lymphocytes and macrophages. This can be seen in muscle biopsies, which are helpful both for diagnosis and to exclude other muscle disorders. In the muscle tissue of patients with myositis, several inflammatory and immune- mediating molecules are produced. These are likely to be important for the clinical symptoms and for the muscle fiber damage and loss of muscle strength. These molecules are of interest as targets for new therapies that are more specific than gluco- corticoids and other immunosuppressants that are used today. A better under- standing of the key molecules that cause the disease could lead to the development of new and better therapies for patients with polymyositis or dermatomyositis. Molecules Present in Muscle Tissue in Inflammatory Conditions Cytokines are important signaling molecules in inflammatory responses and immune regulation. These cytokines are secreted by cells in the immune system and by endothelial cells in the lining of blood vessels. Endothelial cells control the passage of compounds and white blood cells into and out of the bloodstream (19). Hypoxia could also be a consequence of loss of microvessels, capillaries, in muscle tissue that is a typical finding in dermatomyositis. Interestingly, a loss of capillaries seems to be an early event in dermatomyositis. More recently, we have also observed a reduced number of capillaries in muscle tissue in patients with polymyositis (unpublished data). As oxygen supply is crucial for aerobic muscle metabolism, hypoxia can have several negative consequences that affect the working capacity of muscles and could also affect the nutritional status of patients with chronic muscle inflammation. Pharmacological Treatment As presented earlier, glucocorticoids have become the cornerstone of treatment since 1950 when they were first introduced. Although treatment with glucocorticoids made a dramatic improvement in patient survival, it soon became apparent that some patients with myositis do not respond at all and very few patients recover their former muscle performance. Furthermore, as also discussed previously, a disadvantage of high-dose glucocorticoid treatment is the substantial risk of side effects. For these reasons, combination therapies with other immunosuppressive agents have been developed. Today, glucocorticoids are still recommended as baseline treatment (starting doses of 0. Other therapies that are used in severe cases are cyclophosphamide, cyclosporine A, mycophenylate mofetile, tacrolimus or infusions with high doses of intravenous immunoglobulin. Only a few of these drugs have been tested in controlled trials of adequate size and duration to show beneficial effects. They are mostly used based on observed beneficial effects in occasional individuals or reported case series. Glucocorticoids can have profound negative effects on metabolism, making the immunosuppressive treatment of myositis an important issue with regard to nutritional status in patients with polymyositis and dermatomyositis. Prognosis Currently, there is only limited information available on the survival rate of patients with polymyositis and dermatomyositis. The few studies are mainly based on cohorts from one hospital; they are not population based and they include only a small number of patients. With this limitation in mind, the 5-year survival was estimated to be 95% and 10-year survival to be 85 or 89% in two recent papers (28,29). This may be a catabolic effect caused by the systemic chronic inflammation, or it may be a side effect of long-term glucocorticoid treatment, which is a well-known muscle catabolic agent. In patients with myositis, muscle wasting may also be caused by muscle atrophy and damage as a consequence of muscle inflammation, or to nutritional deficits depending on difficulties with swallowing. Because of the inflammatory process and to glucocorticoid treatment, muscle mass may be replaced by fat and muscle wasting may not always be signaled by weight loss. A more appropriate way to follow nutritional status is by assessment of body composition. This can be done by a dual energy X-ray absorptiometry scan, typically used for bone densitometry. Little detailed information on nutritional status is available in the literature that is specific for polymyositis and dermatomyositis. Here, we summarize available infor- mation that we find relevant for patients with myositis after a literature survey. The oxygen is provided to muscle by blood vessels including the small capillaries. By using the macronutrients carbohydrates (glycogen), proteins (amino acids) and fat (fatty acids and glycerol)energy is produced in the mitochondria in muscle cells, and the muscle will be able to contract (30). Glucocorticoids A special problem in patients with myositis that may affect nutritional status is their need for long-term (often over months to years), high-dose, glucocorticoids. Glucocorticoids are used to suppress muscle inflammation by acting on most cell types. The effects on T lymphocytes and macrophages are both direct and indirect, by influencing the mediators released by these cells (31,32). Via this mechanism, blocked gene expression of proinflammatory cytokines will occur and therefore the amount of these inflammatory molecules will decrease. As mentioned previously, it was noticed early that treatment with glucocorticoids had negative effects on muscles and may induce muscle atrophy and also a catabolic state. Glucocorticoids act in several ways to retard growth and promote muscle protein breakdown (35). Some strategies that could possibly be undertaken to counteract these negative effects of glucocorticoids are discussed later. Role of Exercise The catabolic effect of glucocorticoids on muscle tissue is likely to contribute to muscle wasting in patients with myositis who are also affected by catabolism from the muscle inflammation and from physical inactivity as well. In patients who have undergone renal transplant, the negative effect of low or moderate doses (1012 mg per day) of glucocorticoids on muscles was reversed by physical exercise. There are numerous benefits of exercise in terms of nutritional status in healthy individuals. Although many of these effects have not been evaluated specifically in patients with myositis, they could be assumed to be attributable to these patients. In healthy individuals, the muscle protein metabolism after exercise is negative and food intake is needed in order to gain muscle mass. Because patients with myositis already experience a catabolic state owing to glucocorticoid treatment, the post-exercise meal could be even more important to prevent further muscle protein breakdown. This is best achieved by digesting a combination of carbohydrates and protein after the exercise bout (52). It seems as if early post-exercise ingestion of a nutrient supplement, as opposed to ingestion 2 hours after training, enhances the anabolic effect of whole-body protein (53,54). The fact that patients with myositis are in a catabolic state caused by inflammation and steroid use, this approach, otherwise mostly used by athletes, might be of use in these patients.
