Chronic lymphocytic leukaemia during pregnancy: management and thoughts.

Chronic lymphocytic leukaemia (CLL) is the most common leukaemia in the Western world. Despite this fact, its coexistence with pregnancy is extremely rare, with few cases reported in the literature. Given the rarity of this event, it is difficult to conduct large prospective trials to evaluate diagnostic, management, and outcome aspects.

Heparin in pregnant women with previous placenta-mediated pregnancy complications: a prospective, randomized, multicenter, controlled clinical trial.

To assess whether antithrombotic prophylaxis with low-molecular-weight heparin effectively prevents recurrence of late pregnancy complications, 135 women with previous history of preeclampsia, hemolytic anemia, elevated liver enzymes and low platelet count syndrome, intrauterine fetal death, fetal growth restriction, or placental abruption who had been referred within the 12th gestational week were randomized to medical surveillance alone (n = 68) or combined to open-label nadroparin (3800 IU daily subcutaneous injections) treatment (n = 67) in the setting of a randomized, parallel-group, superiority trial, run in Italy from April 2007 to April 2010. Primary outcome was a composite end point of late-pregnancy complications. Analysis was by intention to treat.

Small size-specific umbilical vein diameter in severe growth restricted fetuses that die in utero.

Background: To study changes in umbilical vein (UV) blood flow velocity, diameter and blood flow volume in intrauterine growth retardation (IUGR) fetuses who die in utero (IUD-IUGR).

Methods: Twelve singleton IUGR fetuses who died in utero below 600 g were included. All cases had abnormal uterine and umbilical arteries PI.

Simultaneous measurements of umbilical venous, fetal hepatic, and ductus venosus blood flow in growth-restricted human fetuses.

Objective: The purpose of this study was to evaluate the changes in the distribution of the umbilical venous blood flow to the liver and to the ductus venosus in intrauterine growth-restricted human fetuses in relationship with dilation of the ductal isthmic diameter.

Study Design: Umbilical venous flow, ductus venosus blood flow, and blood flow to the fetal liver were measured in 56 severely intrauterine growth-restricted fetuses with an abnormal pulsatility index of the umbilical artery and were compared with 137 normal control fetuses. Percentages of umbilical venous blood flow through the ductus venosus and to the fetal hepatic lobes were calculated.
