[Direct collection of information during blood donation in blood mobiles]. / La saisie directe des informations lors d'un don de sang en collecte mobile.

Direct data storage, in the presence of the donor, ensures a realistic reliability and erases any deferred interpretation of the essential information for a good donation identification. Computers can help relieve this restraint. Indeed the evolution of microcomputers (increased capacity and power, decreased weight and volume, and good performance in any use makes them more and more accurate. Associated use of barcodes and microcomputers gives a nonmanual non-human line of words: donor-donation-analysis-blood products-patient. We found, working that way, the following advantages: Information secured. No deferred inputs. Instart comparison of the information on the donor's past history. Accurate donation-donor connection. Such a system represents one more step towards a continuous line of treatment from Donor to Patient in regard of Blood Transfusion Safety.

[Lewis-negative blood group. Definite frequency, probable prognostic value in adult psychiatry]. / Groupe sanguin Lewis négatif. Fréquence certaine, valeur pronostique probable en psychiatrie de l'adulte.

The negative Lewis blood type is meaningfully more frequent with our psychiatric patients than with the general population. The theoretical interest of this fact is certain for the reason of two particularities of this blood type. It is not genetically and definitely determined at birth: the absence of passing over negativity through positivity seems to constitute a factor in favour of the blossoming of a psychiatric pathology. It is in connection with the secretory aptitude of some cells: this fact opens some perspectives for the comprehension of the deficits in the neurotransmitters. The application of theory will be confirmed by others statistics. But it indeed appears that the control of the chemiotherapy is more difficult with the negative Lewis blood type patients.

[The Lewis blood group is more frequently nonexpressed in psychiatry than in the general population]. / Le groupe sanguin Lewis est plus fréquemment non exprimé en psychiatrie que dans la population générale.

The Lewis-negative blood group seems to occur more frequently in psychiatry than in the overall population. The Lewis group is not genetically determined at birth as Lewis-positive or negative; the latter occurs significantly more often among 219 "overall" psychiatric patients than in the overall population: 47% instead of 10%. As a first approximation, the absence of transition from its negativity to positivity seems to constitute a favoring factor for the subsequent clinical development of a psychiatric syndrome, without allowing to predict its nature or severity. For the other blood groups, the genetic determination of which is irreversible, the same sample shows the same repartition as in the overall population.
