[Parenteral nutrition using an arteriovenous fistula].

Seventeen children with extended resection of the small intestine, chronic intestinal adynamia or Crohn's disease were given prolonged parenteral nutrition through an arteriovenous fistula, exclusively of associated with enteral nutrition. This new technique allowed the patients to lead a normal life, with a normal growth. In more than 22 patient-years no infectious complication occurred. Thrombosis of the fistula remains the most important complication; il can be prevented thanks to a controlled infusion technique, including adjunction of platelet aggregation inhibiting drugs and the maintenance of proper hemodynamics.

[Disturbances of chemotaxis in protein-calorie malnutrition (author's transl)].

A study of specific and non-specific immune functions was performed in 14 children presenting with severe malnutrition, before and after parenteral hyperalimentation by central catheter. Anomalies of cellular functions (reduction of the percentage of E rosettes and deficient proliferation with mitogens) were rarely found. Measurements for serum immunoglobulins did not show any anomaly; however reduced percentages of EAC rosettes and important increase in "null" cells were found in about one third of the cases. The main finding was a decreased serum chemotactic activity following activation of the classic complement pathway. This was found in 12 children and returned to normal values in all cases after hyperalimentation.

[Chronic neutropenia and Crohn's disease in childhood. Report of 2 cases ].

Two children in whom Crohn's disease complicated the course of chronic neutropenia are reported. These two cases had other features in common: consanguinity of the parents, relatively good clinical tolerance of neutropenia and almost complete lack of blood and marrow eosinophils. The possible relationships between the 2 diseases are discussed.

[Choleriform diarrhea in a case of ganglioneuroblastoma. Demonstration of a high blood level of vasoactive intestinal peptide (VIP)].

The case of a 6-month old infant presenting with profuse diarrhea associated with increased plasma V.I.P. (600 pg/ml) is reported. The increased excretion of V.I.P., most probably of tumoral origin may be considered as responsible for the diarrhea. The discovery of an increased plasma level of V.I.P., occuring during a choleriform diarrhea, leads to evoke and search for a tumoral process of the APUD system.
