...embryos lost (from spontaneous or therapeutic abortion) during the first 4½ months of pregnancy he took skin grafts for eight patients. Four failed to take, probably because of infection, Dr. Snyderman suggested. The other four took. Most remarkable was the fact that a postage-stamp-size piece of fetal skin grew and eventually covered a much larger area on a burn victim's body. Two patients have maintained the grafts for nearly a year, whereas adult skin would have sloughed off in less than a month...
...things can be wrong with the heart to require surgery. Some defects may be present in a child's heart or great vessels at birth (estimated annual U.S. incidence: 30,000 to 80,000 births). The great vessels (pulmonary artery and aorta) may be transposed, not harmful during fetal life but usually fatal soon after birth. Often there is a hole in the wall (septum) between the auricles or between the ventricles; there may be a hole permitting all four heart chambers to communicate. The aorta may override (straddle) both right and left ventricles. The neck (infundibulum...
...right side, as she has been taught." The sound of the patient's deep and rapid breathing signals the onset of each new contraction; they are now coming three minutes apart. In a quiet moment, a microphone attached to the doctor's stethoscope picks up the fetal heartbeat, amplified to thunderous volume. "That's fine," he remarks. "One hundred forty-five and going strong." Between contractions, Mrs. Usill complains of hunger. "I could do with some honey," she says, and it is brought...
...inquiry quickly focused on oxygen. At Harvard, experiments with mice proved that too little oxygen at critical stages of fetal development caused a host of abnormalities, including a condition similar to R.L.F. In Melbourne, Australia, Dr. Kate Campbell recalled that R.L.F. had first appeared in Women's Hospital when new incubators were installed and all premature babies began to get liberal doses of oxygen. In Birmingham, England, doctors pointed out that the incidence of R.L.F. rose when premature infants began to get larger and longer doses of oxygen. When oxygen was reduced, the frequency of the disease decreased...
...animals. But the English ophthalmologists are hopeful that their preliminary experiments contain some preliminary answers. It now seems more probable than ever that too much oxygen in the incubator, combined with sudden removal to normal air, may cause retrolental fibroplasia in premature children. And too little oxygen in the fetal blood stream may help to bring about the same condition...
