Comparative StudyConcurrence of mouthing movement and rapid eye movement/non-rapid eye movement phases with advance in gestation of the human fetus.
To evaluate whether mouthing movement in the human fetus is related to advance in gestational age and whether such movement is concurrent with rapid eye movement or non-rapid eye movement phases, 26 fetuses from 28 to 41 weeks' gestation were observed for 60 continuous minutes with real-time ultrasonography. It was evident that regular mouthing movement every 300 to 600 msec concurred with the non-rapid eye movement period, from 35 weeks' gestation to term. Random mouthing movements that occurred at a wide range of intervals from 300 msec to approximately 525 seconds were observed predominantly during the rapid eye movement period and were unrelated to advance in gestational age. These observations were discussed in relation to biologic implications.

Case ReportsNeuromuscular blockade with magnesium sulfate and nifedipine.
A patient who received tocolysis with nifedipine developed neuromuscular blockade after 500 mg of magnesium sulfate was administered. This reaction demonstrates that nifedipine can seriously potentiate the toxicity of magnesium. Caution should be exercised when these two tocolytics are combined.

The incidence of gunshot wounds in the civilian population is increasing. Likewise, pregnant women are more frequently sustaining wounds of the abdomen. ⋯ Guidelines for management are suggested. Select patients may be observed if the following conditions are present: mother's condition is stable, the entrance wound is below the fundus of the uterus, the missile can be radiographically demonstrated to be in the uterine cavity, there is a negative abdominal examination, and there is no blood in the urine or gastrointestinal tract.
