[Surgical excision of a hepatoma complicating chronic tyrosinemia (author's transl)].

A girl with chronic hereditary tyrosinemia is described in whom the diet caused an immediate resolution of tubular defect and rapid healing of the rickets. However cirrhosis was not prevented and at the age of 8 she developed a hepatoma. Complete surgical excision was possible and she remained well 15 months later. The value of blood alpha-fetoprotein levels and liver echotomography to monitor the course of the disease is emphasized. The apparent ineffectiveness of the low phenylalanine and tyrosine diet in preventing hepatic complications is discussed.

[Severe neonatal respiratory distress with linear inspiratory pressure-volume curve].

Twenty-four newborns with severe respiratory distress, treated by mechanical ventilation, are investigated by inspiratory pressure-volume curve. The curves are obtained by slow continuous inflation technique. Two shapes are described: concave curve, ten newborns (group I), linear curve, fourteen newborns (group II). The gestational age is over 36 weeks in both groups. Determination of respiratory mechanics is indicated when mean AaDO2 is higher than 500 torr in both groups, and when there is a hypercapnia (PaCO2 = 53 +/- 11 torr, with p less than 0.05) in group II. Mechanical ventilation is conducted with individually adjusted PEEP in group I, and without PEEP in group II. Twelve hours after; mean AaDO2 in group I (260 +/- 101 torr) and in group II (420 +/- 188 torr) are significantly different (p less than 0.05). The variance analysis in group II shows that PaCO2 and pH are normalized (p less than 0.001). All the newborns in group I recovered. Three newborns in group II died. Group I can be assimilated to hyaline membrane disease in full-term neonates. Practically, the cases of neonatal respiratory distress in which PEEP is not indicated can be identified by the functional characteristics of group II.

[Propionicacidemia. A report on two cases (author's transl)].

Two cases of propionicacidemia are reported. The first patient was a child aged 16 months with psychomotor retardation, severe disturbances of wakefulness, and vomiting; the second case concerned a new-born baby with metabolic acidosis and neurological disorders. In both cases the diagnosis of propionicacidemia was made after the discovery of ketonuria, and raised blood ammonia and glucose levels. Appropriate dietary measures led to great improvement in the first case, and nearly normal psychomotor development in the second case at 7 months of age. Problems related to biotin sensitivity, leucine intolerance, and raised blood ammonia levels are discussed.
