  • Asbestosis

    serch.it?q=Asbestosis

    Asbestosis is long term inflammation and scarring of the lungs due to asbestos. Symptoms may include shortness of breath, cough, wheezing, and chest pain. Complications may include lung cancer, mesothelioma, and pulmonary heart disease. Asbestosis is caused by breathing in asbestos fibers. Generally it requires a relatively large exposure over a long period of time. Such levels of exposure typically only occur in those who work with the material. All types of asbestos fibers are associated with concerns. It is generally recommended that currently existing asbestos be left undisturbed. Diagnosis is based upon a history of exposure together with medical imaging. Asbestosis is a type of interstitial pulmonary fibrosis. There is no specific treatment. Recommendations may include influenza vaccination, pneumococcal vaccination, oxygen therapy, and stopping smoking. Asbestosis affected about 157,000 people and resulted in 3,600 deaths in 2015. Asbestos use has been banned in a number of countries in an effort to prevent disease.

  • Chest radiograph

    serch.it?q=Chest-radiograph

    A chest radiograph, colloquially called a chest X-ray (CXR), or chest film, is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine. Like all methods of radiography, chest radiography employs ionizing radiation in the form of X-rays to generate images of the chest. The mean radiation dose to an adult from a chest radiograph is around 0.02 mSv (2 mrem) for a front view (PA, or posteroanterior) and 0.08 mSv (8 mrem) for a side view (LL, or latero-lateral). Together, this corresponds to a background radiation equivalent time of about 10 days.

  • Tuberous sclerosis

    serch.it?q=Tuberous-sclerosis

    Tuberous sclerosis complex (TSC), is a rare multisystem genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs, and skin. A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, and lung and kidney disease. TSC is caused by a mutation of either of two genes, TSC1 and TSC2, which code for the proteins hamartin and tuberin, respectively. These proteins act as tumor growth suppressors, agents that regulate cell proliferation and differentiation. The disease is often abbreviated to tuberous sclerosis, which refers to the hard swellings in the brains of patients, first described by Désiré-Magloire Bourneville in 1880.
