In a sixteen year old girl, investigation by routine radiographs and a bone scan suggested a focus of inflammation with a nidus and sclerosis of the acetabulum and overgrowth of the head and neck of the femur. Removal of the lesion by an anterior approach(More)
Cardiac myxomas are rare tumors which can mimic other diseases. We describe a 19-year-old man who presented clinically with polyarteritis nodosa (PAN). Muscle biopsy showed vasculitis, but corticosteroid and immunosuppressive therapy was initially effective. Cardiac myxomas were found by echocardiogram when the disease relapsed and were resected surgically.(More)
Pregnancy concomitant with Wegener's granulomatosis is extremely rare: so far, only four cases have been published. The authors report a fifth case where the disease appeared during the post-partum period, a situation which has already been noted in two of the published cases. Interruption of a subsequent pregnancy was followed by a flare-up of the disease(More)
this paper proposes an approach for the specification of human-machine dialogue for interactive process control applications. This approach is based on a formal modelling of the Human-Machine System behaviour. This modelling makes it possible to deduce the user requirements and then to identify the User Interface (UI) objects. The formal aspect allows the(More)

We report the case of a 71-year-old patient who developed knee pain aggravated by movement with pseudo-blockage which was found to be related to a secondary localization of a primary lung cancer.
