Recurrent tetraamelia and pulmonary hypoplasia with multiple malformations in sibs.

A term amelic female infant was born to an apparently nonconsanguineous Arab Moslem couple. This was followed by the birth of 4 normal children. Afterwards, in 2 subsequent pregnancies, 2 amelic fetuses were diagnosed by transabdominal ultrasonography in the 18th and 12th week of gestation. Pregnancies were terminated and on autopsy both amelic fetuses had severe lung hypoplasia and aplasia of the peripheral pulmonary vessels. The first fetus also had apparently low-set ears and micrognathia, whereas the last had hydrocephaly and left cleft lip beside the lung hypoplasia and aberrant pulmonary artery. This appears to be a new autosomal recessive malformation syndrome.

The effect of disopyramide on uterine contractions during pregnancy.

To evaluate the effect of disopyramide on uterine contractions during pregnancy, the drug was given for 48 hours to 10 women with indications for labor induction. Placebo was given to 10 other women with the same indications for induction. During the study period, regular uterine contractions occurred in 10 women in the study group, as compared with none in the control group (p less than 0.0001). Eight women in the study group were delivered of infants within 48 hours, as compared with none in the control group (p less than 0.0001). The mean time until the appearance of regular uterine contractions in the study group (4.15 +/- 1.76 hours) was significantly shorter (p less than 0.001) than that in the control group (56.13 +/- 5.28 hours). Patients who were not delivered of infants within 48 hours received other medications (prostaglandin E2, oxytocin). The mean maternal blood level of disopyramide at the time of appearance of uterine contractions was 1.52 +/- 0.9 mg/ml. The mean maternal level at delivery was 0.93 +/- 0.43 mg/ml and the cord blood level at the time of delivery was 0.33 mg/ml (cord blood/maternal level ratio = 0.36, r = 0.73, p less than 0.05). These results indicate that disopyramide should not be used in pregnancy for antiarrhythmic purposes because it may induce uterine contractions and delivery.

Cocaine: maternal use during pregnancy and its effect on the mother, the fetus, and the infant.

Cocaine was previously regarded as a soft drug causing only mild damage. Its use during pregnancy, however, creates a variety of grave medical problems which necessitate immediate attention not only on the part of internists and psychiatrists but also, and more particularly, by obstetricians and pediatricians. The pregnancy of a cocaine-using woman must be carefully managed and regarded as a high-risk one. This in view of the numerous obstetric risks caused by the drug, notably premature separation of the placenta, increased incidence of stillbirths, congenital malformations, premature births, and intrauterine growth retardation. The neonatal monitoring must be focused on prevention of complications resulting from the withdrawal syndrome and associated conditions such as pneumonia, severe weight loss, and contagion from the mother. Moreover, efforts must be made to ensure a strict observation of the infant outside the hospital in view of the far greater incidence of idiopathic infant death in such cases. Owing to the sharp rise of the regular and occasional use of the drug and since pregnant women tend on anamnesis to deny any drug taking, we recommend a test of maternal urine for cocaine and other drugs whenever a suspicion to this effect arises. It is also advisable to test for the presence of such drugs in the urine of the neonate in cases of reasonable suspicion of maternal use during pregnancy, though a negative outcome of the urine test naturally does not rule out a possible use. Strict monitoring of positive cases, accompanied by preventive treatment, may contribute a great deal toward a reduction of perinatal morbidity and mortality associated with cocaine use use.
