A multiparous woman (VDRL-negative, Rh-positive) was admitted in labor to an Air Force hospital at an estimated 38 weeks of pregnancy. A 1,928-gm, male infant was delivered precipitously. Immediately after expulsion, the infant was noted to be extremely pale and weak, although it breathed and cried promptly. A second male infant, of similar weight, was then delivered spontaneously and appeared normal. The contrast in appearance between the two infants was striking. The first infant, receiving oxygen by mask, had obvious pallor without cyanosis or respiratory retractions. The respirations were irregular and gasping, the cry feeble. Neither peripheral nor precordial pulses of the first baby were palpable, but a faint, rapid heart beat was heard on auscultation. The second infant was pink, active, and crying vigorously, even without the administration of oxygen. Neither baby had edema, a palpable spleen or liver. A diagnosis of posthemorrhagic shock in the first infant was made. Soon thereafter, a single placenta with velamentous insertions of the cords (Fig. 1) at each side was delivered. The umbilical vessels of one cord were totally avulsed at the velamentous insertion, except for a thread-like strand which later separated in handling. Thirty milliliters of dextran were injected immediately into a cutaneous vein of the first infant, approximately 15 minutes after delivery. The baby immediately became much more vigorous and developed a discernible pulse. Further improvement occurred when 30 ml of Group-O, Rh-negative blood was injected, approximately 30 minutes later. The first hemoglobin determination, deferred until 20 hours of age to avoid unnecessary handling was 10.6 gm/100 ml in the first infant, as compared to 16 gm/100 ml in the second. Further replacement and comparative studies are shown in Figure 2. Neither infant developed icterus during the stay in the nursery. Both infants received a transfusion toward the end of the hospitalization. Blood studies and development of both infants were normal at 2 and 5 months, respectively.

AbstractNeonates with vein of Galen aneurysmal malformation (VGAM) presenting with severe cardiac failure and pulmonary hypertension represent a challenge for endovascular therapy. When early treatment is required, the small femoral arteries in this population are usually difficult to cannulate. Alternatively, the umbilical vessels offer a natural pathway to reach the lesion. Therefore, prenatal diagnosis of VGAM allows for delivery planning, perinatal management, and embolization through umbilical approach, thus leading to better outcomes.

The object of the author was a careful examination of facts in the Natural History of the Salmon, which hitherto have been taken merely upon opinion. He watched and carefully observed personally the deposition of the ova or eggs of the salmon under the gravel,—its long confinement in that situation,—its growth into a fish about an inch in length,—its ascent through the gravel, and rapid growth whilst in the rivers: the journals of observation were partly read to the Society. Twenty weeks was the period from the time of deposition to their bursting the outer shell; for nine days longer they continued under the gravel as fishes, drawing their nourishment from the yoke of the egg, which is of course attached to them by the umbilical vessels or, more properly, by the ompholo-mesenteric vessels.

Abstract The aorta-gonad-mesonephros (AGM) region is a potent hematopoietic site in the midgestation mouse conceptus and first contains colony-forming units–spleen day 11 (CFU-S11) at embryonic day 10 (E10). Because CFU-S11 activity is present in the AGM region before the onset of hematopoietic stem cell (HSC) activity, CFU-S11 activity in the complex developing vascular and urogenital regions of the AGM was localized. From E10 onward, CFU-S11 activity is associated with the aortic vasculature, and is found also in the urogenital ridges (UGRs). Together with data obtained from organ explant cultures, in which up to a 16-fold increase in CFU-S11 activity was observed, it was determined that CFU-S11 can be increased autonomously both in vascular sites and in UGRs. Furthermore, CFU-S11 activity is present in vitelline and umbilical vessels. This, together with the presence of CFU-S11 in the UGRs 2 days before HSC activity, suggests both temporally and spatially distinct emergent sources of CFU-S11.
