Comparative StudyHaemodynamic effects of oxytocin (syntocinon) and methyl ergometrine (methergin) on the systemic and pulmonary circulations of pregnant anaesthetized women.
The haemodynamic effects of oxytocin (Syntocinon) and methyl ergometrin (Methergin) were studied in 9 healthy females in the first trimester of pregnancy. The patients were anaesthetized with sodium thiomebumal, pethidine and pancuronium bromide and ventilated on a Manley respirator. 10 i.u. oxytocin given as an i.v. bolus brought about a fall in femoral arterial pressure of 40%, systemic resistance 59% and pulmonary resistance 44% 30 sec after injection. ⋯ No changes were seen in the haemodynamic parameters during infusion of 80 mU oxytocin for 10 min. 0.2 mg Methergin brought about an increase in the femoral arterial pressure of 11%, pulmonary arterial pressure 27% and wedge pressure 31%, with no changes in the other measured parameters. The use of oxytocic drugs in patients with compromised circulation is discussed.

Randomized Controlled Trial Clinical TrialInhibition of puerperal lactation. A double blind study of bromocriptine and placebo.
Bromocriptine and placebo were randomly allocated for three weeks to 52 postpartum patients requiring lactation suppression. Bromocriptine significantly lowered plasma prolactin levels and suppressed breast milk, breast pain and engorgement quicker than placebo. No side-effects were noted and rebound lactation did not occur. Menstruation appeared to re-start sooner when Bromocriptine was given.

The significance of human chorionic gonadotropin in blood serum for the early diagnosis of ectopic pregnancy.
Determination of human chorionic gonadotropin (HCG) values in the serum by the radioimmunoassay technique, was performed in 23 women with suspected ectopic pregnancies. In 16 cases the values of HCG were high and the diagnosis of ectopic pregnancy was verified by laparoscopy and laparotomy. In 7 cases low HCG values were found and ectopic pregnancy was excluded. The detection of HCG in the serum was found to be an excellent tool for the early diagnosis of ectopic pregnancy, thus helping to prevent the dangerous sequelae which follow the late diagnosis of this condition.

Histamine metabolism in normal pregnancy and in toxaemia of pregnancy.
The urinary excretion of histamine and its metabolites, methylhistamine, methylimidazoleacetic acid and imidazoleacetic acid, was measured under standardized dietary conditions in 24 women with normal pregnancies and in eleven patients with toxaemia of pregnancy. In addition, histamine metabolism was studied in five healthy women at delivery and in four other healthy pregnant women during treatment with aminoguanidine, which is an inhibitor of diamino oxidase (histaminase). A slight increase in the urinary excretion of methylimidazoleacetic acid was observed in normal pregnancy as well as in toxaemia of pregnancy compared to non-pregnant women. ⋯ Despite the very high diamino oxidase activity in the plasma and in the uterus during pregnancy, there were no signs of altered catabolism of endogenous histamine in the pregnant women. Smoking increased the urinary excretion of the quantitatively dominant histamine metabolite, methylimidazolacetic acid, in pregnant subjects as it also does in nonpregnant subjects. The necessity of standardized dietary conditions in the study of histamine metabolism in man was again emphasized.

Case ReportsPrenatal diagnosis of soft-tissue malformations by ultrasound and X-ray.
This study presents four cases of fetal soft-tissue malformations diagnosed during pregnancy by ultrasonic scanning and amniography. The series comprises two fetal teratomas, one case of fetal ascites, and one case of a partial mole with coexistent fetus. Diagnostic and differential diagnostic problems are illustrated by a fifth case where the final diagnosis was a big maternal ovarian cyst-adenoma coexistent with a normal fetus.
