Ovine fetal growth curves in twin pregnancy: ultrasonographic assessment.

PURPOSE OF INVESTIGATION: The fetal-lamb model is a fundamental tool for developing clinical applications for the treatment of human fetal pathology (e.g., open fetal surgery). Accurate estimation of gestational age is important to avoid size-related problems during surgery. METHODS: To evaluate the effect of twinning on ovine fetal growth, we followed seven twin pregnancies in Comiso ewes from mating through parturition. Fetal growth indexes (muzzle-occipital and mean abdominal diameters, abdominal circumference, femoral and humeral length) were measured weekly using perimammary ultrasonography and analyzed with a linear quadratic regression model based on natural logarithms of each parameter and fetal age. RESULTS: The model explained > 90% of the variability observed, with determination coefficients of 95% (femoral length, abdominal circumference), 94% (abdominal diameter, humeral length), and 89% (muzzle-occipital diameter). CONCLUSION: Mean birth weight was lower than that reported for singleton fetal lambs, as it is in bigeminal pregnancies in humans, despite the uterine and placental differences between these two species. With the exception of slightly earlier growth deceleration, curves for head and long-bone growth resembled those for singleton ovine fetuses. Ovine fetal growth patterns (like those of humans) in singleton and twin pregnancies are similar.

Complementary therapy for severe Rh-alloimmunization.

PURPOSE OF INVESTIGATION: This report describes successful treatment, using invasive and noninvasive techniques, of a 36-year-old woman (gravida 10, para 0) referred to our center at 13 weeks' gestation for severe Rh alloimmunization. Pre-pregnancy indirect Coombs titers ranged from 1:1024-2048. All nine past pregnancies (conceived with three different partners) had ended in abortion, intrauterine death or neonatal death METHODS: The patient was treated with a single session of plasmapheresis (week 14) immediately followed by five days of immunoglobulin therapy and immunosuppressive therapy based on azathioprine and prednisone (weeks 15-22). Seven fetal transfusions (one intraperitoneal, six intravascular) were performed beginning at 16 weeks. RESULTS: The pregnancy, which was characterized by insulin-dependent gestational diabetes, spontaneously resolving polyhydramnios and peak indirect Coombs titers of 1:65,536, ended at 27 weeks with cesarean section delivery of a viable female weighing 1,000 g. In spite of numerous neonatal complications, the child is physically well at age 3, with normal intellectual and psychomotor development. CONCLUSION: In light of the negative outcomes of the patient's nine past pregnancies, our experience suggests that the early initiation of an integrated approach based on noninvasive and invasive techniques can play a potentially decisive role in the management of severe Rh-alloimmunization.

[To what extent is breast feeding practiced in Italy today?].

OBJECTIVES: During a survey regarding infant health in 7 regions, diffusion and length of time of breast-feeding nowadays in Italy were studied. MATERIALS AND METHODS: By OMS Epi methodology, 210 children sampled from each area of study and specialized health workers carried out the interviews at home using a specific questionnaire. The mothers were questioned about the length of time they breast fed their child. RESULTS: 76% of mothers said they breastfed, 32% said they did it for less than 3 months and 44% for more. In each area, the percentage of breastfeeding was 70% or more. This percentage changed only if the birth weight was very low or the mothers' instruction was high, but this is probably because the most cultured mothers answered easier they breast fed longer. DISCUSSION: It seems that mothers are pro-breastfeeding and, in each region, just a quarter of them don't practise it. Besides, about half women breastfed for more than 3 months. This study doesn't permit us to know why some women don't breastfeed or why they wean their children too early. For this reason, we need to curry out further studies.
