Notes: Abstract A patient with cyclic neutropenia suffered full-thickness loss of her right abdominal wall and thigh muscles from clostridial myonecrosis. No port of entry was definitely identified. The sepsis and myonecrotic process were controlled by resuscitative measures, extensive multisession debribement, and hyperbaric treatment.

Notes: The discretization of the incompressible Navier-Stokes equation on boundary-fitted curvilinear grids is considered. The discretization is based on a staggered grid arrangement and the Navier-;Stokes equations in tensor formulation including Christoffel symbols. It is shown that discretization accuracy is much enhanced by choosing the velocity variables in a special way. The time-dependent equations are solved by a pressure-correction method in combination with a GMRES method. Special attention is paid to the discretization of several types of boundary conditions. It is shown that fairly non-smooth grids may be used using our approach.
