[The problem of radiation exposure during radiography of the entire spine].

The stimulus for this investigation concerning radiation exposure during radiography of the spine, particularly in children with scoliosis, is the fact that there are no data in the literature. In 16 series of measurements we studied the effect of grids, kilovoltage, focus-film distance and film-screen systems using dosimeters. The use of grids led to a 5-7 times increase in radiation dose compared with exposures without grids.

Effects of vasopressin and desmopressin on memory. A double-blind study in 40 healthy volunteers.

In a study involving 40 healthy student volunteers, 10 subjects were given lysine vasopressin at a dose of 0.4 ml (23 IU) per day in 3 divided doses for 15 days by the nasal route. Ten subjects were given desmopressin at a dose of 0.

[Interhemispheric disconnection syndrome in glioma of the posterior part of the corpus callosum].

The syndrome of interhemispheric disconnexion has been systematically researched in 10 cases of medial and posterior callosal tumours. The cases have been documented with CT Scann and two of them were anatomically verified. Two had a complete disconnexion syndrome; another, whose lesion was situated on the forceps major, had no sign of disconnexion.

[Confabulatory anomia from visual and tactile agnosia in a case of multi-infarct dementia. Neuropsychological study (author's transl)].

Observation of a patient suffering from a double softening of the brain (inner side of right temporal lobe, left occipital lobe). Clinically, Korsakoff's syndrome, right quadranopsia, pure alexia, tactile and visual agnosia concerning objects, colors and faces. Relative integrity of elementary perceptions (matching tests), impairments of stimulus identification (Lissauer's associative agnosia).
