[Physiopathology of osteoporosis (author's transl)]. 1979

J P Camus, and A Prier, and J Crouzet

Osteoporosis is the result of the progressive loss of bone substance which occurs during a lifetime. Its histomorphological characteristics have been well-defined and it appears to be a single entity more particularly related to the general problem of cellular senescence. The rate at which bone is lost can be influenced by many events or general factors, known or unknown, which are capable of accelerating or slowing down its progression. The period when the fracture threshold is passed appears to depend on a bone mass which is weak at the end of the growth period, followed by genetic, mechanical--related more specifically to insufficient muscular activity--, hormonal-hypo-oestrogenemia-factors, and pathological episodes of more rapid demineralization (immobilization, corticotherapy) which become more irreversible with advancing age.

UI MeSH Term Description Entries
D006961 Hyperparathyroidism A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
D006980 Hyperthyroidism Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE. Hyperthyroid,Primary Hyperthyroidism,Hyperthyroidism, Primary,Hyperthyroids
D007103 Immobilization The restriction of the MOVEMENT of whole or part of the body by physical means (RESTRAINT, PHYSICAL) or chemically by ANALGESIA, or the use of TRANQUILIZING AGENTS or NEUROMUSCULAR NONDEPOLARIZING AGENTS. It includes experimental protocols used to evaluate the physiologic effects of immobility. Hypokinesia, Experimental,Experimental Hypokinesia,Experimental Hypokinesias,Hypokinesias, Experimental
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010024 Osteoporosis Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.

D004032 Diet Regular course of eating and drinking adopted by a person or animal. Diets
D004967 Estrogens Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
