Quantitative and qualitative hydrologic balance for a suburban watershed with a separate sewer system (Nantes, France).

A qualitative and quantitative budget at the outlet of the storm-water runoff system of a small suburban watershed is presented together with some data regarding waste-water. 445,000 m3 (34% of the rain-water volume) were drained by the storm-water runoff system and 40,879 m3 by the waste-water system from September 2002 to March 2004. Storm-water runoff is generally not heavily polluted with regard to trace metals but concentrations occasionally exceed the standards for surface water of good quality. On the contrary, pesticides (diuron and glyphosate) have very high concentrations especially in spring and autumn when their use is maximum. As the St Joseph storm-water runoff is finally discharged into the Erdre River, measures to reduce the use of these pollutants should be considered.

Experimental study and modelling of zinc and lead migration in sandy soils due to stormwater infiltration.

Heavy metals emitted by road traffic are contaminants of roadside soils and can potentially migrate through the soils down to groundwater during runoff water infiltration. Stormwater management requires a better understanding of the mechanisms involved in the transport and particularly chemical interactions between heavy metals and the solid matrix. Experiments with open dynamic systems and modelling with a mixing-cells-in-series model have been performed to identify the main reactions which govern the migration of zinc and lead in sandy soils. Binary and ternary exchange experiments have been performed and a numerical modelling was proposed to describe zinc and lead mobility in column experiments.

[Genital malformations and castration. Femininity, sexuality at adolescence].

A study group has been constituted at the Hôpital des Enfants-Malades in order to analyse the relational approach with adolescent girls with various disorders and malformations of the genital tract followed since childhood. This group has been using a methodology which has already been applied to psychological aspects of other somatic diseases. Endocrinologists, gynecologists and psychoanalysts have weekly discussions about clinical cases. Their discussions are tape-recorded. The transcriptions are analysed by the whole group in order to evaluate the objective and subjective data concerning patients, families and doctors. We intend to discuss problems which appear to be the most important in relation to these disorders. Whatever the somatic problem is, these girls' future is also determined by their psychic reality and also that of their families and doctors. This psychic reality integrates and modifies the objective data as well as their environment.

[Mother-child relationship and psychosocial dwarfism].

Results of a study of 11 children presenting what is known as psychosocial dwarfism are discussed. Clinical observations and projective tests (Rorschach) show the crux of the problem within the mother-child relationship to originate in reciprocal feeling of hate between mother and child. This hatred constantly manifests itself in daily life through acts and behaviour rather than through verbal expression. These results are in agreement with our findings in the psychotherapies of one child and one mother. Characterizing the mother-child relationship as ont of aggressiveness and hatred fits with other author's findings who describe the mother's neglect and rejection. However we think it is more adequate as it applies to both ends of the relation: mother on one hand, child on the other.

Children talk about death.

As a psychoanalyst in a pediatric nephrology ward, I have listened to children talking about dying and death. As soon as a child can express himself freely on this subject, no further age-dependent progress concerning the concept of death can be observed. Faced with disease and death, the child is led to the same images and conclusions, to the same order of ideas as the adult. This clearsightedness does not prevent the appearance of mechanisms of defence against the idea of death. Faced with the silence of the adult, the dying child shuts himself up in loneliness. However, the child does not want to be alone: he craves to be recognized. During the time left before his death, to be recognized is for him synonymous with: "to be recognized near death". To let a child talk about his death is to let him talk about his life, to bring him the only possible help, that is, to be with him till the end.

Sleep patterns in infants under continuous feeding from birth.

Continuous parenteral or enteral feeding of infants with major gastrointestinal problems (prolonged diarrhoeas, inflammatory digestive illnesses, anatomical anomalies necessitating surgical intervention, etc.) brings about a prolonged modification in nutritional and environmental conditions. The consequence of eliminating the feeding rhythms of the waking-sleeping rhythm in 16 infants between 1 and 8 months old were studied. In most of the infants the duration of sleep was close to that given by Kleitman in normals. Slightly decreased in 4 of the infants, these durations never showed significant differences from normative values. No delay was observed in the maturation of sleep patterns. The percentage and mean length of periods of quiet sleep were practically identical for all infants but a number of them showed large amounts of ambiguous sleep. The fact that none of these values evolved with age should be stressed. Paradoxical sleep periodicity was similar to that of normal infants, while the quiet sleep-paradoxical sleep cycles were shorter. In conclusion, the absence of feeding rhythms appeared not to modify greatly the sleep maturation and organization.

[The child in digestive resuscitation].

Twenty one children who had total parenteral nutrition followed by a constant infusion into the gastrointestinal tract between the 10th and 90th day of life were studied. When normal feeding is resumed the difficulties are related to the lengths of hospital stay, separation from the parents and the lack of contact with adults more than to the techniques of feeding themselves.

[Preliminary psychological evaluation of a group of children before and after renal transplantation].

Eighteen children who have received kidney transplants within the last three years at the Hopital des Enfants Malades in Paris provide material for this survey. We try to find out how these transplants effect the way the children live, and the main psychological problems that they create. This new way of life is characterized by an explosion of vitality, a certain liberation from prior restraint and the possibility of activities which up to then had been difficult or forbidden. However, the necessity for the child to be watched regularly, to attend the hospital for examination, to follow a special diet, to take immunodepressive drugs remind him that he is not cured. Consequences of corticotherapy and the growth retardation remain essential problems for some of them. The child will have to cope with this complex situation which also creates difficulties to acquire independence.

Renal transplantation in children: a psychological survey.

Psychological tests were carried out on 24 children with renal disease during the time they were hemodialyzed and after a minimum of one year after their transplant. These investigations included regular interviews with children and families, drawings and their commentaries, and projective techniques: Rohrschach tests. The results of these investigations indicated that the psychological status of the transplanted child could not be singled out and isolated from the effects of being ill, the different therapeutic procedures, and the personal history. Beyond the appearance adolescents give of a satisfactory social adjustment and beyond the explosion of vitality frequent amongst younger children, an impoverishment of their personality and major difficulties manifest themselves in coping with personal problems and identity crises especialy as far as agressiveness and sexuality are concerned. This neurotic mechanism appears mainly due to the traumatic experiences these children have experienced and their lack of support in mastering them through the verbalization process.

Aspects of communication between patients and doctors: an analysis of the discourse in medical interviews.

The transcripts of tape-recorded interviews of pediatric endocrinologists and patients with Turner's syndrome and their parents were reviewed in consultation with child psychoanalysts in order to evaluate certain aspects of communication between patients and doctors. The transcripts showed that the doctors often talked at cross purposes with the parents and their patients, evading emotional issues in favor of quasi-scientific explanations which the patients and parents did not understand. Parts of the discourse, at times unconscious, have been shown to be of great importance as means of communication. Reviewing the transcripts of the doctor-patients discourse is an excellent way of improving one's therapeutic communication with the patient. The same material can be used for teaching purposes.
