Causes. In trigeminal neuralgia, also called tic douloureux, the trigeminal nerve's function is disrupted. Usually, the problem is contact between a normal blood vessel â in this case, an artery or a vein â and the trigeminal nerve at the base of your brain.This contact puts pressure on the nerve and causes it to malfunction.Trigeminal neuralgia can occur as a result of aging, or it can be related to multiple sclerosis or a similar disorder that damages the myelin sheath protecting certain nerves.Less commonly, trigeminal neuralgia can be caused by a tumor compressing the trigeminal nerve.rigeminal neuralgia can occur as a result of aging, or it can be related to multiple sclerosis or a similar disorder that damages the myelin sheath protecting certain nerves.

The world's first fully synthetic plastic was bakelite, invented in New York in 1907 by Leo Baekeland who coined the term 'plastics'. Many chemists have contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger who has been called the father of polymer chemistry and Herman Mark, known as the father of polymer physics.

When patients ask why is it called âplasticâ surgery, I usually reply, âWe had plastic before plastic had plastic.â The term plastic means to mold, and is from the Greek word plastikos. It was first used to describe a specialty of surgery in 1837. The first plastic, on the other hand, was made by Alexander Parkes in 1855 by mixing cellulose and nitric acid to produce Parkesine, more commonly known as Celluloid. Leo Hendrik Baekeland invented the first synthetic plastic, Bakelite, in 1907.
