As a result of the increased use of drugs that enhance fertility, and the advent of in vitro fertilization and embryo transfer over the last 2 decades, the incidence of multifetal pregnancies has increased exponentially. In parallel with this increase methods of care for women carrying multiple fetuses have become more complex and well developed. Importantly, it has become obvious that in the case of such pregnancies the rates of mortality and morbidity of both fetuses and mothers, particularly in cases where four or more fetuses are involved, are extremely high. Improvements in the techniques of assisted fertilization should result in fewer yatrogenic multifetal pregnancies and a commensurate decrease in related risks. Fetal reduction seems to be an acceptable method of improving maternal and fetal outcome in high order multiple pregnancies despite the many unresolved medical and ethical dilemmas.

PURPOSE: The aim of the study was to assess perinatal outcome of pregnancy burdened with maternal addiction in comparison with an unselected population from a European transition country. MATERIALS AND METHODS: Data on pregnancies complicated by illicit drug abuse (n = 85) managed during a 10-year period (1997-2007) at Split University Hospital were analyzed. Data on the type of drug, course of gestation and labor, and on perinatal outcome were considered. Data on all non-dependence pregnancies recorded during the study period were used as a control group. RESULTS: During the study period, there were 85 dependence-complicated pregnancies (0.2%). Use of heroin alone during pregnancy was recorded in 51 women (50%), methadone alone in 6 (7%), and a combination of heroin and methadone in 9 (11%). Premature delivery was significantly more common in the group of pregnant addicts (21% vs. 6%); 49% of pregnant addicts were carriers of hepatitis C virus (HCV) and 14% of hepatitis B virus (HBV). Neonatal abstinence syndrome developed in 61 infants (7%) born to addicted mothers. There were 4 cases (4.6%) of early neonatal death; 7 neonates had 5-minute Apgar score < or = 7 (8%); 29 neonates had low birth weight for age (33%); and 7 neonates had congenital anomalies (8%). The risk of various congenital anomalies was 3-fold in the group of children born to addicted mothers. CONCLUSION: Addiction pregnancies present a small but high-risk group according to perinatal outcome. Appropriate obstetric and neonatal care can reduce the rate of complications in these pregnancies and improve perinatal outcome.

Ponderal index (fetal weight in grams x 100 / (fetal length in centimeters) 3) (PI) is one of the anthropometric methods used to diagnose impaired fetal growth. Irrespective of the infant's position on the growth-weight-for-gestational age charts, PI is low in malnourished infants and high in obese ones. As fetal growth is affected by ethnicity, geographic location and socioeconomic status, we developed standards for neonatal PI, and assessed the effects of gestational age, sex and maternal parity. Data on 5798 newborns from singleton pregnancies born in the Department of Gynecology and Obstetrics, Split University Hospital, were retrospectively analyzed. Over a 15-month period in 2000/2001, 5596 newborns from 24 to 42 weeks of gestation were born. The other 202 newborns, born from 24 to 34 weeks of gestation in the ten year period, 1990-1999, were added because of the small number of preterm infants; ensuring a minimum of 30 to fill up at least infants in each gestational week. All mothers were of Caucasian origin. Stillbirths and fetuses with congenital malformations were excluded. The 10th, 50th and 90th percentiles, mean values with standard deviation of PI and the 10th, 50th, and 90th percentiles of birth weight and birth length are presented separately at weekly intervals. PI showed linear correlation with gestational age from 24 to 39 weeks, after witch the data plateaued. Sex and parity had no impact on PI in infants born between 24 and 37 weeks. Analysis of variance revealed PI to be significantly higher in female than in male newborns, and in multiparous than in nulliparous infants after 37 weeks of gestation. In conclusion, gestational age is the most important factor of neonatal PI. The effects of sex and parity on PI should only be considered in term neonates.
