Nuages gris: Nuages gris (] ; French, lit.  "Grey Clouds"), S.199 or Trübe Wolken, is a work for piano solo composed by Franz Liszt on August 24, 1881.  It is one of Liszt's most haunting and at the same time one of his most experimental works, representing, according to Allen Forte, "a high point in the experimental idiom with respect to expressive compositional procedure."'  If we must look for biographical parallels with the music, perhaps the bleakness of mood is connected with difficulties faced by Liszt at the time of composition, when he was suffering from dropsy, failing eyesight, and severe injuries sustained in a fall down the stairs of the Hofgärtnerei seven weeks earlier.

Scapular fracture: A scapular fracture is a fracture of the scapula, the shoulder blade.  The scapula is sturdy and located in a protected place, so it rarely breaks.  When it does, it is an indication that the individual was subjected to a considerable amount of force and that severe chest trauma may be present.  High-speed vehicle accidents are the most common cause.  This could be anywhere from a car accident, motorcycle crash, or high speed bicycle crash but falls and blows to the area can also be responsible for the injury.  Signs and symptoms are similar to those of other fractures: they include pain, tenderness, and reduced motion of the affected area although symptoms can take a couple of days to appear.  Imaging techniques such as X-ray are used to diagnose scapular fracture, but the injury may not be noticed in part because it is so frequently accompanied by other, severe injuries that demand attention.  The injuries that usually accompany scapular fracture generally have the greatest impact on the patient's outcome.  However, the injury can also occur by itself; when it does, it does not present a significant threat to life.  Treatment involves pain control and immobilizing the affected area, and, later, physical therapy.
