Who is at increased risk for developing mesothelioma? Written by Linda Woodhouse
Since late 1800's Asbestos has been mined and used commercially. The use of Asbestos dramatically increased during World War II and since early 1940's millions of Americans have been exposed to asbestos dust working within industries where initally risks were not known. There has been widespread exposure to Asbestos by workers within shipyards, mines and mills, producers of asbestos products, workers in heating and construction industries, and other tradespeople and an increase risk of deveolping mesothelioma has been result. . Today, U.S. Occupational Safety and Health Administration (OSHA) sets limits for acceptable levels of asbestos exposure in workplace. By contrast, British Government's Health and Safety executive (HSE) states formally that any threshold for mesothelioma must be at a very low level and it is widely agreed that if any such threshold does exists at all, then it cannot currently be quantified. For practical purposes, therefore, HSE does not assume that any such threshold exists. People who work with asbestos wear personal protective equipment to lower their risk of exposure. The risk of asbestos-related disease increases with heavier exposure to asbestos and longer exposure time. However, some individuals with only brief exposures have developed mesothelioma. On other hand, not all workers who are heavily exposed develop asbestos-related diseases. Family members and others living with asbestos workers have an increased risk of developing mesothelioma, and possibly other asbestos-related diseases. This risk may be result of exposure to asbestos dust brought home on clothing and hair of asbestos workers.
| | Knee pain and runningWritten by Karri Koivula
Running with knees that hurt and are not getting better trough time is no fun, and being addicted to running doesn’t help either.Fortunately, pain isn’t always a definite sign of tissue damage; instead it can be protective pain that is coming from entities called myofascial trigger points. Pain from trigger points can feel like its coming from knee joint or patellae, while it’s actually coming from contraction knots in quadriceps muscles. What makes things quite enigmatic is that these knots can sometimes reside high in quadriceps muscles, far from where actual pain symptom is felt. It’s not uncommon for knee pain to be solely or partially muscular. It’s also common for doctors to overlook trigger points as a possible pain cause, because at this point there is no imaging equipment in use, which could verify their existence. For now, only way to find out if trigger point are part of pain equation, is manually palpating and searching for them from muscles. There are not many doctors who do this, or know how to do this, or think that it’s even beneficial to do this.
