This report summarized our experience with a consecutive series of 800 women referred for midtrimester amniocentesis for prenatal diagnosis of a fetal genetic abnormality. The results are compared before and after introduction of sonography immediately prior to the tap as a routine adjunct of the procedure. Following use of sonography there was a statistically significant reduction in the frequency of bloody taps, and an increase in the proportion of successful and informative initial taps. Moreover, in many instances sonography provided information useful for identification of fetal abnormalities or for management of pregnancy. These findings support the recommendation that examination by sonography should be utilized routinely as an adjunct to amniocentesis, despite the uncertainities relating to possible long-term adverse effects of intrauterine exposure to ultrasound.

In 3400 midtrimester amniocenteses, 68 fetuses had abnormal findings. Three women elected to continue their pregnancies and the remainder chose terminations. Of these, 29 were cared for in our hospitals. Pregnancy termination was carried out in gestations averaging 21.6 +/- 2.3 weeks and fetal weights averaging 531 +/- 351 g. Three prostaglandins techniques were used, two of which proved to be effective. Dosages employed were comparable to those used in early second trimester pregnancy terminations. Side effects were similar; one retained placenta occurred. We have used a multidisciplinary counseling approach for these couples and have restricted ourselves to the medical aspects of their problems. Techniques are described for the psychologic support of the couple during this stressful period.

The purpose of the present study was to determine whether sincere and faked grip strength measurements could be distinguished from one another by the patterns of measurements obtained for the five handle (hand size) positions of the Jamar dynamometer. Healthy subjects were instructed on different trials to give a sincere, maximal effort or to fake weakness of grip. Results were that the patterns did differ for sincere and fake trials, but not as strongly as expected. The recommendation is made that further research be done using patients with upper extremity injury.
