[Boerhaave syndrome: a rare cause of acute thoracic pain].

In a 74-year old female patient suffering from acute thoracic pain, vomiting, and dyspnoea, the diagnosis of Boerhaave's syndrome was made. After medical treatment the patient was dismissed in a sufficiently satisfactory condition. If symptoms like vomiting, severe thoracic pain, pneumomediastinum, pneumothorax or hydropneumothorax on the left side occur, a rupture of the oesophagus should be taken into account especially in case of abuse of alcohol. The early diagnosis is decisive for the course of the disease and a lethality reduction.

An efficient finite-element algorithm for 3D layered complex structure modelling.

In this paper an efficient finite-element method (FEM) algorithm for complicated three-dimensional (3D) layered type models has been developed. Its unique feature is that it can handle, with memory requirements within the abilities of a simple PC, arbitrarily shaped 3D elements. This task is achieved by storing only the non-zero coefficients of the sparse FEM system of equations. The algorithm is applied to the solution of the Laplace equation in models with up to 79 layers of trilinear general hexahedron elements. The system of equations is solved with the Gauss-Seidel iterative technique.
