It is a blue-black coloration that shows a normal skin undertone when palpated.

Polyuria, Polydipsia and Possible Diabetes Insipidus?
Discussion
The body is smart. It has mechanisms for maintaining balances within the body in a closely controlled manner but allows for a variety of states. This is very true for fluid balance in the body which is highly controlled between almost all of the major body organ systems. When fluid is low, the sensor sends signals for us to drink, and conserves fluid until we can. When the fluid is high, the kidneys excrete the excess and sends signals not to drink. Usually it works very well. While there are many pathological states that can cause polyuria and/or polydipsia, the most common reason is excessive fluid intake beca...

What Types of Hand Stereotypies are Associated with Rett Syndrome?
Discussion
Lady MacBeth and patients with Rett Syndrome (RS) are obviously not alike other than in making similar hand motions. In Shakespeare’s MacBeth (5.1.25-30), Lady MacBeth was driven into madness because of her murderous guilt and tries to wash the blood off her hands as she sleepwalks.
Doctor. What is it she does now? Look, how she rubs/ her hands.
Gentlewoman. It is an accustomed action with her, to seem thus/ washing her hands. I have known her continue in this/ a quarter of an hour.
