Randomized Controlled TrialA pilot study of preemptive morphine analgesia in preterm neonates: effects on head circumference, social behavior, and response latencies in early childhood.
Use of preemptive analgesia in Neonatal Intensive Care Units is recommended for severe and/or invasive procedures. However, the potential long-term consequences of such analgesia, which may be prolonged, are only beginning to be studied. In this pilot study, a subset of subjects previously enrolled in the Neurological Outcomes and Preemptive Analgesia in Neonates (NEOPAIN) trial was assessed at early childhood. ⋯ Parents described morphine treated children as having more social problems, an effect specific to creating and maintaining friendships (Cohen'sd: -0.83, effect size large). Despite the small sample size and the preliminary nature of this study, these results are strongly suggestive of long-lasting effects of preemptive morphine analgesia. A larger investigation with more comprehensive assessments of some of these key features will enable a more complete understanding of the relationship between preemptive morphine treatment and long-term neurocognitive, behavioral, and adaptive outcomes.

Comparative StudyCharacteristics and behaviors of mothers who have a child with fetal alcohol syndrome.
Fetal alcohol syndrome (FAS) is a leading cause of birth defects and developmental disabilities. The objective of this study was to identify the characteristics and behaviors of mothers of children with FAS in the United States using population-based data from the FAS Surveillance Network (FASSNet). FASSNet used a multiple source methodology that identified FAS cases through passive reporting and active review of records from hospitals, specialty clinics, private physicians, early intervention programs, Medicaid, birth certificates and other vital records, birth defects surveillance programs, and hospital discharge data. ⋯ A significant proportion of mothers (9-29%) had another child with suspected alcohol effects. Compared to all US mothers, they were also significantly more likely to be on public assistance, to be on Medicaid at their child's birth, to have received treatment for alcohol abuse, to have confirmed alcoholism, to have used marijuana or cocaine during pregnancy, to have their baby screen positive for alcohol or drugs at birth, to have had an induced abortion, to have had a history of mental illness, to have been involved in binge drinking during pregnancy, and to have drunk heavily (7 days/week) during pregnancy. These findings suggest that it is possible to identify women who are at high risk of having a child with FAS and target these women for interventions.
