Case ReportsPregnancy in a patient with a history of myocardial infarction and coronary artery bypass grafting.
A 37-year-old woman conceived after experiencing a myocardial infarction and undergoing three-vessel aortocoronary artery bypass grafting. Pregnancy was complicated by angina, which was successfully treated with propranolol and bed rest. At term the patient underwent vaginal delivery, without evidence of intrapartum myocardial ischemia or failure.

Functional development of human eye movement in utero assessed quantitatively with real-time ultrasound.
Functional development of eye movement in the human fetus in utero was assessed quantitatively, with real-time ultrasound. A pair of lens-derived echoes was used as a landmark to evaluate positional deviation with eye movement. The frequency of eye movement was measured either with 1-minute continuous observations or at 1-minute cross sections. ⋯ Three critical ages, with respect to physiologic development of fetal eye movements, were evident: 22 to 25, 30 to 33, and 38 to 41 weeks. The first and the second indicate the onset of the moderate-frequency and high-frequency eye movements, thereby implying a transition, presumably to a state of so-called rapid eye movement and a rise of rapid eye movement, respectively. The third represents full maturation of the mechanisms, that is, non-rapid eye movement and rapid eye movement.

Comparative StudyCesarean delivery of the second twin after vaginal delivery of the first twin.
Cesarean birth of twin B after the vaginal delivery of twin A is an infrequent event. There is little information in the literature documenting outcome of vaginal-abdominal delivery. ⋯ Twenty-one cases of combined vaginal-cesarean section deliveries were managed at our institute in a 10-year period. There was no apparent increase in maternal and perinatal morbidity and mortality when twin B was delivered by cesarean section after vaginal delivery of twin A.

Atraumatic delivery in cases of malpresentation of the very low birth weight fetus at cesarean section: the splint technique.
A technique to assist in the atraumatic delivery of the very low birth weight fetus in cases of malpresentation at cesarean section is described; the technique minimizes potential trauma associated with version and/or extraction techniques. Use of uterine relaxing anesthetic agents and subsequent risk of hemorrhage are avoided.
