From these trials we see that breast cancer mortality decreased by about 25% in women aged 5069 years and by 18% in women in their 40s.

Time correlation A prerequisite for recognition is a relevant time correlation between the development of jumpers knee and the knee-loading work with continued jumping/running discount zithromax 250 mg on line. The relevant time correlation will usually be that the first symptoms of the disease develop some time after commencement of the stressful work (weeks/months depending on the severity and nature of the load) purchase 100mg zithromax fast delivery. If the onset of the symptoms does not occur in close connection with a relevant load (immediately or within a few days after the exposure), this will indicate that there are other causes of the disease. Furthermore, jumpers knee must not have been diagnosed prior to relevant exposure at work. Managing claims without applying the list Only jumpers knee is covered by group D, item 4, of the list of occupational diseases. Jumpers knee not covered by the list may in special cases be recognised after submission of the claim to the Occupational Diseases Committee. This may for instance be a jumpers knee developed after 127 (a) Many hours of hard weight-training per week, where the person in question has not, or only to a very limited extent, been exposed to loads in connection with jumping/running (b) Extraordinarily severe weekly loads for less than one month (for weeks) The practice of the Occupational Diseases Committee in the assessment of claims not covered by the list will frequently be updated on the website of the National Board of Industrial Injuries. Examples of decisions based on the list Example 1: Recognition of right-sided jumpers knee (professional football player for 8 years) A 32-year-old male football player was diagnosed by a medical specialist with right-sided jumpers knee (tendinosis patellaris), consistent with the tendon attachment under the kneecap. For the past 8 years he had been a professional player in one of the big clubs in Denmark, and he had practised at least once every day. The training was varied and consisted in general football playing, interval training, running, and weight-training with heavy weights. The football player practised indoors on parquet floors and outside on grass and man-made grass. He was a regular on the team and therefore started on the pitch in most of the games, which meant that in the course of one season he played a game approximately once a week. His total load from jumping and running was estimated at about 20-25 hours per week. For a number of years, the football player played ball and practised for more than 12 hours per week on average and was diagnosed with right- sided jumpers knee (tendinosis patellaris dxt. Practice as well as games were characterised by jumping/running with many starts and stops (acceleration/deceleration) while flexing and extending the knee and with a continual load on the patellar tendon. There is also good time correlation between the load and the onset of the disease. In the course of the last year she gradually developed complaints in her left knee, right above the kneecap, with pain and tenderness as well as stiffness. Her complaints were particularly evident when she was standing on her left leg and shooting and running. She had never before had any symptoms from her left knee, and there was no known trauma to her left knee. A medical specialist in a clinical examination diagnosed her with left-sided jumpers knee (patellaris tendinitis), consistent with the tendon attachment to the upper part of the kneecap, which was confirmed by an ultrasound examination. In the course of her 3 years as a professional player she practised on an average 4-5 times a week and from 3 to 5 hours at a time. The training alternated between handball training and various handball exercises, stamina training by means of running, and various strength and weight-lifting exercises. To this should be added games about once a week, which, like most of the training apart from running, took place indoors in a sports centre 1 The European version of handball 128 on a hard surface. Practice as well as games were characterised by quick changes in pace and many quick starts and stops as well as jumping up and down, which led to stresses on the left kneecap tendon. For more than 3 years the handball player played handball and practised more than 12 hours per week on average and after 3 years she was diagnosed with left-sided jumpers knee consistent with the tendon attachment at the upper part of the kneecap. Training as well as games were characterised by high pressure on the kneecap in connection with jumping/running with frequent starts and stops (acceleration/deceleration) while flexing and extending of the knee. In addition, by far the major part of the load occurred indoors on a hard surface. Example 3: Recognition of right-sided jumpers knee (professional badminton player for 4 years) A 28-year-old woman had for 4 years worked as a professional badminton player in a big Danish club when she developed a right-sided jumpers knee with pain, tenderness, swelling and slightly restricted motion of the knee. Her career as a professional badminton player had involved hard training for several days a week and matches more or less every weekend. The matches involved jumping/running with continued starts/stops while flexing and extending her knee. The badminton player suffered an exposure relevant for the development of jumpers knee, in the form of jumping/running 25-30 hours a week for several years and with frequent starts and stops while flexing and extending the knee. Example 4: Claim turned down left-sided jumpers knee (professional football player working part time) A 25-year-old man in a clinical examination was diagnosed with left-sided jumpers knee (tendinitis patellaris) consistent with the tendon attachment to the lower part of the kneecap. He was a part time employee in a bank and worked 25 hours a week as a bank adviser. Furthermore he was employed the last 2 years on a part time contract in a Jutland League football club. The training mostly consisted in football playing and exercises on a grass course. One of the 3- 4 weekly training sessions consisted in intensive weight-training and strength training. Even if there is a diagnosis of left- sided jumpers knee, the load as a semi-professional football player was not sufficient. The football player on an average practised and played games 8 hours a week, including 2 hours of weight-training. Therefore he does not meet the requirements for exposure in the form of jumping/running with quick and frequent starts and stops while flexing and extending the knee at least 12 hours a week, perhaps in combination with intensive weight-training at least 5 hours a week or playing on a hard surface, which might give grounds for reducing to 8 hours the requirement to the total weekly load. Nor are there grounds for submitting the claim to the Occupational Diseases Committee, the football player not having experienced any extraordinary knee loads constituting any particular risk of developing left-sided jumpers knee. Example 5: Claim turned down right-sided jumpers knee (professional football player for 6 months) 129 A 25-year-old female football player was diagnosed by a medical specialist with right-sided jumpers knee with severe and chronic degeneration (tendinosis patellaris), consistent with the tendon attachment to the lower part of the kneecap. By then she had been a professional football player for 6 months and practised several hours a day, including approx. In addition she had played 20 whole football games as a professional in the course of 6 months. Games as well as training were characterised by jumping/running with frequent starts and stops while bending and extending the knee, and there was pressure on the kneecap. It appeared that a year previously she had jumpers knee in the same place, which developed in connection with football playing in her leisure time as member of an ordinary football club. But there had been a continued tendency to pain in the knee after severe loads during training. Even though the stresses as a professional football player for 6 months were sufficient to develop jumpers knee, the football player previously, and without correlation with work, suffered from jumpers knee. This substantially increases her disposition to develop the disease again due to chronic degeneration of the tendon attachment. Nor are there any grounds for submitting the claim to the Occupational Diseases Committee. This is because it was not possible to recognise the disease, it not being likely beyond reasonable doubt that the disorder was caused, solely or mainly, by working as a football player.
