Caisson Disease Synonyms
fessional cleaning by a dentist or dental hygienist. Its rough surface provides an ideal medium for bacterial growth. Calculus can even extend into pockets created between the tooth and the gum.
Decompression sickness; Diver’s disease
Definition Caisson disease is a medical condition related to sudden exposure to a reduction in the pressure surrounding the body. It can happen in many situations: in divers ascending from a dive, in workers coming out of a pressurized caisson or mine, or in pilots if the cabin pressurization system of an aircraft fails. This causes inert gases (mainly nitrogen), which are normally dissolved in body fluids and tissues, to come out of physical solution and form gas bubbles in blood and tissues. Symptoms include “the bends” (joint pain) in shoulders and knees, headache, visual disturbances, extreme fatigue, lack of strength, breathing difficulties (“the chokes”), and in some cases cardiovascular collapse, unconsciousness and paralysis. The only effective treatment is recompression, carried out in a recompression chamber, where the pressure is gradually decreased.
Calculus Definition Hardened dental plaque is called calculus. Hardening occurs if dental plaque is not being removed and accumulats in the absence of proper oral care resulting in the calcification of the plaque by the minerals of the salvia. Calculus can not be removed by rinsing or tooth brushing. Once formed, it should be removed by pro-
Cancer Synonyms Malignant tumors; Neoplasms
Definition Cancer is the general term for more than 100 different distinct diseases that can affect every part of the body. Cancer is defined by a rapid abnormal cell growth beyond usual boundaries that can affect adjoining parts of the body including other organs. This process is referred to as metastasis which is the major cause of death from cancer. Cancer is caused by changes in the genes responsible for cell growth and repair, driven by interaction between genetic host factors and external agents. These external agents can be categorized into physical carcinogens, chemical carcinogens and biological carcinogens. Prevention strategies play a vital role in reducing the burden of cancer as up to one third of all cases could be avoided by: changing tobacco and alcohol use, adjusting dietary and physical activity patterns or reducing exposure to sunlight, etc. Early detection and treatment of cancer is another key element in reducing the burden of cancer as it significantly improves the prognosis. When cancer is treated, the main objectives are curing, prolonging life and improving the quality of life of the patients affected. The common treatment methods are surgery, radiotherapy and chemotherapy.
