Just in time for Easter, here’s a brand new entry from the Department of Extraordinary Eggshell Artists: Polish artist Piotr Bockenheim spends countless hours using a tiny electric drill, an awesomely delicate touch, and immeasurable patience to turn goose egg shells into exquisite sculptures.

Head over to Piotr’s DeviantART gallery to view more.

Carved Goose Shells Piotr Bockenheim

Unless you spent hundreds upon hundreds of hours with a tiny electric drill carving intricate patterns into eggshells the last few months, you may have yet to reach your Easter egg decorating potential. One person who clearly has is artist Piotr Bockenheim who uses a reductive drilling technique to transform goose eggs into slitherting tangles

Ganglion cyst, aka "Bible bump", aka "Let’s hit you with a large book!"

Given the name “Bible cyst” or “Bible bump” from the original “treatment” of hitting the deformity with a Bible or other large book, ganglion cysts are actually considered tumors. Over 60% of the non-cancerous tumors of the hand are ganglionic, but their etiology is still not completely understood.

The first description of these tumors was given by Hippocrates as “knots of tissue containing mucoid flesh”, but the first theories of their origins weren’t put forth until 1746, when one Dr. Eller wrote a descriptive paper on them. He believed that they came from synovial herniation,  or rupture through the tendon sheath, and that they were true cysts.

Later theories recognized that the tumors were growths arising from ganglionic sheaths and not encysted fluids or mucoid tissues, but the old theory of “just smack it with a heavy object to burst it and make the body reabsorb it” still stuck around for a long time. Though bursting the tumor can cause temporary disappearance, this often causes more serious recurrence and additional growth. As these tissues are not cancerous, it’s generally recommended to leave them alone when they’re not interfering with normal function. Sometimes they can press against other tendons or nerves and necessitate aspiration or surgical removal, but the incidence of recurrence is over 40%. In about 75% of cases, the “cyst” will disappear or significantly decrease on its own.

So, yeah, don’t let anyone convince you to let them smack you with a heavy object, just because you have one of these growths! It’s a bad idea to let people smack you with heavy objects, just as a general rule…

Hemorrhage and petechiae 

Petechiae are the smallest class of purpura (under 3 mm), caused by hemorrhage of capillary blood vessels at the surface of the skin. They look like tiny red or purple spots that don’t blanche (turn white) when you press down on them, like, say, a sunburn does.

In forensics, petechiae can indicate death due to compression of the thorax or throat, including death due to manual strangulation or hanging. In this case, death was caused by the complete compression of the thorax by a rolling mill, which caused massive hemorrhaging in the face, due to the blood being pushed upwards. There are also petechial hemorrhages throughout the chest and collarbone area.
