X-linked ichthyosis is no "cure." One of the aims of treatment is to reduce scaling by removing the excess, flaky scales, and keep the skin hydrated. This can be achieved using a variety of topical creams. Research is ongoing with regard to the use of gene therapy to treat XLI. In the 1960s, recessive x-linked ichthyosis was distinguished clinically from other ichthyoses. The Ichthyosis Support Group - http://www.ichthyosis.org.uk.

Kutta condition Kutta condition The Kutta condition is a principle in steady-flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies with sharp corners, such as the trailing edges of airfoils. It is named for German mathematician and aerodynamicist Martin Kutta. Kuethe and Schetzer state the Kutta condition as follows: In fluid flow around a body with a sharp corner, the Kutta condition refers to the flow pattern in which fluid approaches the corner from both directions, meets at the corner, and then flows away from the body. None of the fluid flows around the sharp corner. The Kutta condition is
