Queen Alexandra of Great Britain, (1844–1925), consort to Edward the VII, as the inscription on the bronze statue of her at the London Hospital, notes, "Introduced to England the Finsen light cure for Lupus, and presented the first lamp to this hospital". Etymology
The term "lupus" (meaning "wolf" in Latin) to describe an ulcerative skin disease dates to the late thirteenth century, though it was not until the mid-nineteenth that two specific skin diseases were classified as lupus erythematosus and lupus vulgaris. The term may derive from the rapacity and virulence of the disease; a 1590 work described it as "a malignant ulcer quickly consuming the neather parts; ... very hungry like unto a woolfe". See also

Disuse atrophy of the muscle occurs i.e., shrinkage of muscle fibre finally replaced by fibrous tissue (fibrous muscle)
Other causes include Guillain–Barré syndrome, West Nile fever, C. botulism, polio, and cauda equina syndrome; another common cause of lower motor neuron degeneration is amyotrophic lateral sclerosis. Diagnosis
Differential diagnosis
Myasthenia gravis – synaptic transmission at motor end-plate is impaired
Amyotrophic lateral sclerosis – causes death of motor neurons, although exact cause is unknown it has been suggested that abnormal build-up of proteins proves toxic for the neurons. See also
