Commotio (Nielsen)
Carl Nielsen's ''Commotio'' or ''Commotio for Organ'', Opus 58, was composed between June 1930 and February 1931. The composer's last major work, it was first performed privately on 24 April 1931 in the chapel at Christiansborg Palace in Copenhagen. Background ''Commotio'' was considered by Nielsen to be a particularly important work. In a letter to his son-in-law Emil Telmányi on 24 February 1931 he wrote: "None of my other works has demanded such great concentration as this: an attempt to reconstitute what is truly the only valid organ style, the polyphonic music that is especially suited to this instrument, which for a long time has been regarded as a kind of orchestra, which it absolutely is not." Nielsen also commented on the length of the piece: at 22 to 24 minutes, it was longer than any of Bach's organ works.Niels Bo Foltmann, "Carl Nielsen: Piano and Organ Works"Carl Nielsen Edition, ''Royal Danish Library''. Retrieved 6 November 2010. There was great interest in the pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Commotio Cordis
Commotio cordis (Latin, "agitation / disruption of the heart") is a rare disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region) at a critical instant during the cycle of a heartbeat. The condition is 97% fatal if not treated within three minutes. This sudden rise in intracavitary pressure leads to disruption of normal heart electrical activity, followed instantly by ventricular fibrillation, complete disorganization of the heart's pumping function, and cardiac arrest. It is not caused by mechanical damage to the heart muscle or surrounding organs and is not the result of heart disease. Its incidence in the United States is fewer than 20 cases per year, often occurring in boys participating in sports, most commonly in baseball when a ball strikes a player in the chest. Commotio cordis can occur only upon impact within a narrow window of about 40 milliseconds in the cardiac electrical cycle, explaining why it is ...

Commotio Retinae
Berlin's edema (commotio retinae) a common condition caused by blunt injury to the eye. It is characterized by decreased vision in the injured eye a few hours after the injury. Under examination the retina appears opaque and white in colour in the periphery but the blood vessels are normally seen along with "cherry red spot" in the foveal region. This whitening is indicative of cell damage, which occurs in the retinal pigment epithelium and outer segment layer of photoreceptors. Damage to the outer segment often results in photoreceptor death through uncertain mechanisms. Usually there is no leakage of fluid and therefore it is not considered a true edema. The choroidal fluorescence in fluorescent angiography is absent. Visual acuity ranges from 20/20 to 20/400. The prognosis is excellent except in case of complications of choroidal rupture, hemorrhage or pigment epithelial damage, but damage to the macula will result in poorer recovery. The outcome can be worsened in the case of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
