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''.

Commotio Cordis
Commotio cordis (Latin, "agitation of the heart") is an often lethal 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 time during the cycle of a heart beat, producing what is termed an R-on-T phenomenon that leads to the condition. It is a form of ventricular fibrillation (V-Fib), not mechanical damage to the heart muscle or surrounding organs, and not the result of heart disease. The survival rate is 58%, which is an increase in comparison to years 1993-2012, where only 34% victims survived. This increase is likely caused by the prompt CPR, access to defibrillation and higher public awareness of this condition. Commotio cordis occurs mostly in boys and young men (average age 15), usually during sports, most frequently baseball, often despite a chest protector. It is usually caused by a projectile, but can also be caused by the blow of an elbow or other body part. Being less developed, the thorax ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
