Scars of the Wigner Function.

We propose a picture of Wigner function scars as a sequence of concentric rings along a two-dimensional surface inside a periodic orbit. This is verified for a two-dimensional plane that contains a classical hyperbolic orbit of a Hamiltonian system with 2 degrees of freedom. The stationary wave functions are the familiar mixture of scarred and random waves, but the spectral average of the Wigner functions in part of the plane is nearly that of a harmonic oscillator and individual states are also remarkably regular. These results are interpreted in terms of the semiclassical picture of chords and centers.

[The "pedrada" ("coup-de-fouet") syndrome. A possibility to be considered in acute leg pain].

The authors describe a clinical case of pedrada syndrome in a patient formerly suffering from acute CID. It is a pathology enough rare and easily mistakable with phlebotrombosis of leg but from which is well to be able to do differential diagnosis because of therapy for an affection is clearly contraindicated for the other.

[Post-phlebothrombotic venous insufficiency of the lower limbs. Echo-guided targetted surgery].

The post-phlebothrombotic syndrome surgery has always had a limited space within the limits of the venous lower limbs surgery. This, either for the distrust of surgeon to operate a limb with deep thrombotic phenomenon, or because the range of possible operations is rather limited and constituted by very cruent and devasting operations. The introduction of very accurate method in the preoperative diagnostic, as the echo-color-Doppler, enables an accurate mapping of the new venous post-phlebothrombotic situation and a careful haemodynamic study of the deep or superficial venous circle. Hence, the surgeon has a new and significant chance to perform a minimal surgery generally directed to the ligation of the perforans veins that has become incontinent after the phlebothrombotic insult. In this way, the wide and devasting dissection can be avoided as previous Linton-type interventions.
