Recently, a variable transformation for integrals over smooth surfaces in R3 was introduced in a paper by Atkinson. This interesting transformation, which includes a “grading” parameter that can be fixed by the user, makes it possible to compute these integrals numerically via the product trapezoidal rule in an efficient manner. Some analysis of the approximations thus produced was provided by ...

Since Atkinson first described idiopathic rupture of a normal spleen in 1874, there has been controversy regarding the application of the terms "idiopathic" and "spontaneous". One such case is reported, and the validity of the description "idiopathic" or "spontaneous" discussed.
