Researchers from the Adelphi University discovered in the Paliokastro on Thasos ten skeletal remains, four women and six men, who were buried between the fourth and seventh centuries A.D. Their bones illuminated their physical activities, traumas, and even a complex form of brain surgery. According to the researchers: "The very serious trauma cases sustained by both males and females had been treated surgically or orthopedically by a very experienced physician/surgeon with great training in trauma care. We believe it to have been a military physician". The researchers were impressed by the complexity of the brain surgical operation.In 1991 at the Polystylon fort in Greece, researchers discovered the head of a Byzantine warrior of the 14th century. Analysis of the lower jaw revealed that a surgery has been performed, when the warrior was alive, to the jaw which had been badly fractured and it tied back together until it healed. Islamic world
During the Islamic Golden Age, largely based upon Paul of Aeginas Pragmateia, the writings of Abulcasis (Abu al-Qasim Khalaf ibn al-Abbas Al-Zahrawi), an Andalusian-Arab physician and scientist who practiced in the Zahra suburb of Córdoba, were influential. Al-Zahrawi specialized in curing disease by cauterization. He invented several surgical instruments for purposes such as inspection of the interior of the urethra and for removing foreign bodies from the throat, the ear, and other body organs. He was also the first to illustrate the various cannulae and to treat warts with an iron tube and caustic metal as a boring instrument.
Capillaritis is where the capillaries, usually of the legs or lungs, are inflamed, allowing blood cells to pass through.It may occur in the lungs as pulmonary capillaritis, or in the skin as pigmented purpuric dermatosis. Capillaritis usually affects otherwise healthy people. Capillaritis can take many forms but is made up of tiny red or brown dots that may be spread out or in a group forming a red or brown patch on the skin. One variation, Majocchi purpupa,  forms concentric rings.Capillaritis is a mild condition not requiring treatment. There is no known cure, however capillaritis can disappear within a few weeks, recur from time to time, or persist for years. == References ==
