    Notes: Abstract First results are presented from an experiment scattering laser light from a relativistic electron beam. The 5 cm diameter continuous electron beam of 28 keV kinetic energy and 2.6 A current presents an electron gas of a density of 8×107 cm−3, from which 20 ns pulses of laser light (490 nm) were scattered at a repetition rate of 15 Hz and an average power of 20 mJ per pulse. The Doppler-shifted wavelength of photons backscattered under 180° was analysed with a Fabry-Perot interferometer. This technique provides, for the first time, a non-destructive measurement of the velocity distribution in an electron beam radially resolved in space. The results presented here comprise the direct measurement of the absolute electron energy and the degree of space-charge compensation in the electron beam. The determination of an upper bound of 10−2 for the ratio of longitudinal to transverse electron temperature implies the first direct measurement of a flattened velocity distribution.

    Notes: Abstract A case report of a 2-year-old boy who developed severe post-operative low cardiac output, sudden cardiac arrest and consecutive multiple organ system failure after open heart surgery is described. Initially the hemodynamic situation was stabilized by extracorporeal membrane oxygenation (ECMO) combined with continuous hemofiltration (CHF) carried out for 7 days. Continuous veno-venous hemofiltration (CVVH) was necessary for further 17 days. One episode of plasmapheresis restored transiently a severe post-operative coagulopathy and enabled the removal of the pulmonary artery catheter and the chest tubes.

    Description / Table of Contents: Summary There are numerous pitfalls in the diagnosis of ankle sprains in childhood such as failing to appreciate repeated problems with a postural basis or taking another pathology to be a sprain. It is therefore advisable to be on guard, in traumatic cases of fibular epiphyseal separation and in conditions in the early stages of presentation of spasticity. Severe sprains are rare. Treatment is nearly always conservative and surgery is hardly ever used.
    Notes: Résumé Le diagnostic d'entorse de la tibio-tarsienne chez l'enfant comporte de nombreux pièges tels que la méconnaissance d'une pathologie itérative d'origine posturale, la mise sur le compte d'une entorse d'une pathologie différente. Ainsi il convient de se méfier, dans le cadre des traumatismes, du décollement épiphysaire du péroné ; dans le cadre des pathologies en début d'expression clinique, de la spasticité. L'entorse grave est rare. Le traitement en est pratiquement toujours orthopédique, le traitement chirurgical relevant de l'exception.
