Riley - day syndrome

(Conrad Milton Riley, 20th century, American physician and Richard Lawrence Day, 20th century, American paediatrician), type III hereditary sensory and autonomic neuropathy; also known as familial dysautonomia. This disease occurs primarily in Jewish children, who manifest neuropathic osteoarthropathy, abnormalities of spinal curvature, osteomyelitis, and ischaemic necrosis of bone, in addition to clinical signs and symptoms. In some patients, large portions of the articular surface of the femoral head, femoral condyles and tarsus may disintegrate, with resulting subluxations.
