[Action of injected disopyramide on ventricular arrhythmias and atrioventricular conduction].

The authors have studied the bathmotropic and dromotropic effects of intravenous injection of 100 mg of disopyramide, the therapeutic dose being 1 to 2 mg/kg. Out of the 28 severe arrhythmias studied, it was the ventricular extrasystoles which benefited most from treatment (79% completely successful, while there was a lesser degree of success in treating the ventricular tachycardias (35% completely successful, 30% partially successful). The negative dromotropic effect of injected disopyramide on sub-nodal conduction was studied by an endocavitary technique in 10 patients presenting with a spontaneous onset of disordered intracardiac conduction; the effects were moderate. With the exception of 4 cases who sustained complications involving rhythm and haemodynamics, the clinical and cardiovascular tolerance of patients to the drug appeared to be satisfactory.

[Behaviour of serum concentrations of glucose, immunoreactive insulin and potassium ions in newborns after long term or crash treatments with Partusisten or Partusisten in combination with Isoptin (author's transl)].

The investigation was done on 50 infants born of metabolic healthy mothers. A group of 10 women received short term treatment with Partusisten and Isoptin. Another 10 were treated over the same period with Partusisten only. A further group of 15 received long term treatment (more than 7 days) with Partusisten and Isoptin and a final group of 15 mothers received placebos. Serum concentrations of glucose, immunoreactive insulin and potassium, together with acid-base-status and other important blood chemistry were determined in mothers and newborns directly postpartum. Blood sugar, immunoreactive insulin and potassium were further determined in the newborns 30 minutes, 60 minutes, 2 hours and 6 hours after birth. The results showed that a temporary relative hypoglycaemia occured in the newborns in short term as well as long term treatment with Partusisten or Partusisten in combination with Isoptin. Temporary derangements in insulin-glucose equilibrium were also seen in newborns from mothers receiving long term treatment. It was also demonstrated that approximately 1 hour post-partum, blood sugar and immunoreactive insulin of the newborn attained values compatible with normal carbohydrate metabolism. From these results it is indicated that infants born of mothers, who received tocolytic treatments with Partusisten or Partusisten in combination with Isoptin, should be given sodiumbicarbonate and glucose directly after birth.

[Serum placental lactogen in late pregnancy and its relation to placental villous surface and to placental maturation (author's transl)].

The placentas of ninety-six pregnancies supervised by measurements of human placental lactogen (HPL) were examined. The histometrically determined placental villous surface and the degree of maturation of the villous tissue were compared to HPL-values in late pregnancy and to the weight of the newborn. The production of HPL is dependent on the extent of the syncytiotrophoblast surface area and, in addition, is modulated by the grade of differentiation of the chorionic epithelium. Placental villi with abnormalities of maturation apparently synthesize more HPL than villi of normal maturation.

[Acute coronary thrombosis in a 28 year-old woman].

A 28-year-old woman, with no previous cardiovascular history, was hospitalized for myocardial infarction complicated by bifascicular block followed by complete atrio-ventricular block with a regressive course. A coronary arteriography performed on the 10th day demonstrated a thrombosis of the anterior interventricular artery, the rest of the coronary network being normal. The influence of a dyslipidaemia and the taking of oral contraceptives was discussed as an aetiology.
