The best Viking Age example is the two sided game board from the Gokstad ship (c. 900). This is clearly Nine Men's Morris with its three courts. There is also what is clearly a Nine Men's Morris board on slate found at Peel, on the Isle of Man. (There are photos of this on the World of the Vikings CD-ROM.).
Complications may include bleeding problems, testicular swelling, and inflammation of nerves. Infection during early pregnancy may result in a child born with congenital rubella syndrome (CRS) or miscarriage. Symptoms of CRS include problems with the eyes such as cataracts, ears such as deafness, heart, and brain. Problems are rare after the 20th week of pregnancy.
The symptoms of congenital Brown Syndrome may occur due to shortening of the tendon sheath of the superior oblique muscle or thickening of the sheath that restricts its movement. However, acquired Brown Syndrome may be the result of trauma, surgery, and/or inflammation due to another underlying disorder such as Lupus or Rheumatoid Arthritis. There are several reports in the medical literature of a few rare cases of Brown Syndrome which may be inherited as an autosomal dominant genetic trait.
