Important discoveries as to its mechanism were made during the Blitz of London in 1941. It is a significant problem for those injured in earthquakes, and relief efforts for such disasters often include medical teams equipped to treat survivors with rhabdomyolysis. Signs and symptoms
The symptoms of rhabdomyolysis depend on its severity and whether kidney failure develops. Milder forms may not cause any muscle symptoms, and the diagnosis is based on abnormal blood tests in the context of other problems. More severe rhabdomyolysis is characterized by muscle pain, tenderness, weakness and swelling of the affected muscles. If the swelling is very rapid, as may happen with a crush injury after someone is released from under heavy collapsed debris, the movement of fluid from the bloodstream into damaged muscle may cause low blood pressure and shock. Other symptoms are nonspecific and result either from the consequences of muscle tissue breakdown or from the condition that originally led to the muscle breakdown. Release of the components of muscle tissue into the bloodstream causes electrolyte disturbances, which can lead to nausea, vomiting, confusion, coma or abnormal heart rate and rhythm. The urine may be dark, often described as "tea-colored", due to the presence of myoglobin.
Rhabdomyolysis after consuming quail was described in more recent times and called coturnism (after Coturnix, the main quail genus). Migrating quail consume large amounts of hemlock, a known cause of rhabdomyolysis.In modern times, early reports from the 1908 Messina earthquake and World War I on kidney failure after injury were followed by studies by London physicians Eric Bywaters and Desmond Beall, working at the Royal Postgraduate Medical School and the National Institute for Medical Research, on four victims of The Blitz in 1941. Myoglobin was demonstrated in the urine of victims by spectroscopy, and it was noted that the kidneys of victims resembled those of patients who had hemoglobinuria (hemoglobin rather than myoglobin being the cause of the kidney damage). In 1944 Bywaters demonstrated experimentally that the kidney failure was mainly caused by myoglobin. Already during the war, teams of doctors traveled to bombed areas to provide medical support, chiefly with intravenous fluids, as dialysis was not yet available. The prognosis of acute kidney failure improved markedly when dialysis was added to supportive treatment, which first happened during the 1950–1953 Korean War. Etymology and pronunciation
The word rhabdomyolysis ( ) uses the combining forms rhabdo- + myo- + -lysis, yielding "striated muscle breakdown". Other animals
Rhabdomyolysis is recognized in horses. Horses can develop a number of muscle disorders, many of which may progress to rhabdomyolysis.
