The Early Years of HDTV. Modern-day HDTV has its roots in research that was started in Japan by the NHK (Japan Broadcasting Corporation) in 1970. In 1977, the SMPTE (The Society of Motion Picture and Television Engineers) Study Group on High Definition Television was formed.
What is the connection between Peyronieâs disease and Dupuytrenâs contracture? Many men with Peyronieâs disease also have Dupuytrenâs contracture, a connective tissue disorder that causes scar tissue to harden on the palm of the hand. This causes fingers to curve, much like the penis curves in Peyronieâs disease.
Peyronies disease is a disorder of the tunica albuginea. By producing firm areas, or plaques, it focally interferes with the expansion of this normally pliant material. Peyronies plaque can be either regions of reversible inflammation in early phases of the disease, or permanent scars later on. Regardless of their composition, they alter the shape of the distended corpora cavernosa and cause a bent penile shaft. Like a piece of cellophane tape on the wall of a balloon, they cause uneven inflation and bent erections.
