IBM is often initially misdiagnosed as polymyositis. A course of prednisone is typically completed with no improvement and eventually sIBM is confirmed. sIBM weakness comes on over months or years and progresses steadily, whereas polymyositis has an onset of weeks or months. Other forms of muscular dystrophy (e.g. limb girdle) must be considered as well.
In some applications, for example prosthetic devices such as artificial joints, it is desired to have surfaces very resistant to both chemical corrosion and wear due to friction. Ion implantation is used in such cases to engineer the surfaces of such devices for more reliable performance. As in the case of tool steels, the surface modification caused by ion implantation includes both a surface compression which prevents crack propagation and an alloying of the surface to make it more chemically resistant to corrosion.
Woo was born Wu Yu-Seng (Ng Yu-Sum in Cantonese) in Guangzhou, China, amidst the chaos of the Chinese Civil War at the end of October, 1946. Because of school age restrictions, his mother changed his birth date to 22 September 1948, which is what remains on his passport. The Christian Woo family, faced with persecution during Mao Zedong's early anti-bourgeois purges after the communist revolution in China, fled to Hong Kong when he was five.
Impoverished, the Woo family lived in the slums at Shek Kip Mei. His father was a teacher, though rendered unable to work by tuberculosis, and his mother was a manual laborer on construction sites. The family was rendered homeless by the big Shek Kip Mei fire of 1953. Charitable donations from disaster relief efforts enabled the family to relocate; however, violent crime had by then become commonplace in Hong Kong housing projects.
At age three he was diagnosed with a serious medical condition. Following surgery on his spine, he was unable to walk correctly until eight years old, and as a result his right leg is shorter than his left leg. His Christian background shows influences in his films. As a young boy, Woo had wanted to be a Christian minister. He later found a passion for movies influenced by the French New Wave especially Jean-Pierre Melville. Woo has said he was shy and had difficulty speaking, but found making movies a way to explore his feelings and thinking and would "use movies as a language".
The local cinema would prove a haven of retreat. Woo found respite in musical films, such as The Wizard of Oz and in American Westerns. He has stated the final scene of Butch Cassidy and the Sundance Kid made a particular impression on him in his youth: the device of two comrades, each of whom fire pistols from each hand, is a recurrent spectacle later found in his own work.
Woo married Annie Woo Ngau Chun-lung in 1976 and has three children. He has lived in the United States since 1993.
