Kashin-Beck or Urov disease is described with authority by an astute scholar and clinician, Prof. Nesterov, Director of the Institute for Rheumatism and member of the Academy of Medical Sciences of the USSR in Moscow. The disease is a chronic, disabling, degenerative, generalized osteoarthrosis involving peripheral (symmetrical) joints and spine un-associated with systemic or visceral manifestations. It occurs principally in childhood and results in growth disturbances. It is endemic in Eastern Siberia, Northern China and Northern Korea and is believed to be due to ingestion of cereal grain grown in these areas and infected with the fungus, Fusaria sporotrichiella. The incidence has been considerably reduced and hopefully will soon be eradicated by importing cereals from unaffected areas. This is a classic example of a generalized degenerative joint disease due to environmental causes, unrelated to genetic factors or inborn errors of metabolism.Le morbo Kashin-Beck o Urov es describite con autoritate per le astute scholar e clinico, Professor Nesterov, Director del Instituto pro Rheumatismo e membro del Academia de Scientias Medical del URSS in Moscova. Le morbo es un osteoarthrosis chronic, incapacitante, degenerative, generalisate que implica le articulationes peripheric (symmetric) e le rhachis sin manifestationes systemic o visceral. Illo occurre principalmente in le infantia e resulta in disordines de crescentia. Illo es endemic in Est-Siberia, Nord-China, e Nord-Corea. On opina que illo es debite al ingestion de granos cereal crescente in iste regiones, e inficite con le fungo Fusaria sporotrichiella. Le incidentia del morbo ha essite reducite considerabilemente. On spera que illo tosto va esser eradicate per le importation de cereales ab areas non inficite. Illo es un exemplo classic de un generalisate morbo degenerative articulatori que es debite a causas in le ambiente, sin relation a factores genetic o a innate errores de metabolismo.
