Nonimmune hydrops fetalis is observed with the frequency of 1:3000 cases diagnosed pre- and postnatally. In the following paper the authors analyzed the course of pregnancy complicated by fetal ascites and polyhydramnios with the appearance of colonic ileus and they presented the postnatal condition of the baby The preliminary diagnosis was confirmed after birth and the newborn was operated in the second day of his life. The congenital small bowel atresia was qualified as a III B type (Grossfeld qualification), which is called the "pagoda" syndrome [3]. The colonic atresia is located then around the superior mesenteric vessels, which leads to colonic necrosis (Figure 1).

This paper presents a case of a pregnant woman who was admitted to the obstetrics and gynecology department because of a new onset of uncontrolled diabetes in 27 weeks gestation. The maternal and fetal diabetic complications suggested a chronic character of the disease which must have been undiagnosed before pregnancy. Many of the co-existing infections caused a life-threatening ketoacidosis. Fortunately with the adequate treatment it was possible to ensure appropriate birth weight of the newborn baby despite the ultrasound markers for LGA (Large For Gestational Age) observed during pregnancy. Intensive insulin therapy was obligatorily continued by the mother after the delivery.

Introduction: Methods of macrosomic fetal weight estimation are associated with large deviations and statistically significant errors. Fetal macrosomia might be better predicted by using fetal ultrasound measurements and maternal characteristics., Material and Methods: Ultrasound evaluation of fetal weight was performed in 113 singleton fetuses one week (max. 7 days) before delivery. Retrospectively all newborns with birth weight o A new logarithmic estimation formula proposed by Hart and co. was compared with commonly used formulas of Shepard, Campbell, Hadlock I, Hadlock II, Hadlock Ill. Exclusion criteria were: multiple pregnancies, intrauterine deaths, structural or chromosomal abnormalities. The new formula established by Hart (loge EFW = 7.6377445039 + 0.0002951035 x maternal weight + 0.0003949464 x HC + 0.0005241529 x AC + 0,0048698624 x FL) uses fetal biometric measurements and maternal weight as two different parameters: EFW- estimated fetal weight, maternal weight--weight measured at one week (max. 7 days) before delivery HC--fetal head circumference, AC--abdominal circumference, FL--femur length., Results: The new Hart formula gives the lowest mean percentage error (MPE) : -0.74% and mean absolute percentage error (MAPE) : 3.38%, as compared to other routinely used formulas which presented statistically significantly higher MPE and AMPE With the new formula 84 of estimated fetal weights fell within +5% of the actual weight at birth, 111 within +/- 10% and 112 within +/- 15% and +/- 20%., Conclusions: The presented ultrasound formula demonstrated a more precise macrosomic fetuses weight estimation with the lowest MPE and MAPE as compared to the others and might be introduced when fetal macrosomia is suspected.
