"2011Z"^^ . "Henry Leon Feffer (January 15, 1918 \u2013 May 9, 2011) of Bethesda, Maryland, was an American neurosurgeon. In the mid-1950s, he was one of the first doctors to systematically test whether low-back pain could be relieved with epidural injections of hydrocortisone. Today, physicians routinely give such injections before resorting to more invasive surgery. He was a Washington, D.C. spinal surgeon for more than four decades whose patients included Saddam Hussein."@en . "1918-01-15Z"^^ . . . . . "1918Z"^^ . . . . . "Feffer, Henry Leon"@en . .
