RESUMO
Angiographic diagnosis of an intracerebral aneurysm in a neonate was made on the 13th day of life following persistent neurological symptoms that began at birth. Rupture of the aneurysm probably occurred within the first day of life. This unusual condition should be considered in newborn infants with unexplained neurological signs or intracranial hemorrhage.

Fourteen infants with neonatal abstinence-associated seizures were assessed neurodevelopmentally during the first year of life. Despite abnormal neurologic examination results in eight of 12 infants at 2 to 4 months of age, nine of 12 infants had normal neurologic examination results at follow-up (two infants were unavailable for follow-up; one infant died of acquired immunodeficiency syndrome). Nine neonatal electroencephalograms were abnormal; seven of eight of these abnormal tracings normalized during the follow-up period. Bayley developmental scores remained normal during the first year of life and did not differ from either passively addicted infants without seizures or from published population norms. This short-term favorable prognosis for abstinence-associated seizures differs from that associated with neonatal seizures due to other causes. This observed improvement in neurologic function may be based on replenishment of neurotransmitters following transient depletion in the neonatal period.

A group of 412 infants with birthweights between 501 and 2,500 gm and gestational ages of 36 weeks or less were studied for the influence of both prolonged ruputre of amniotic membranes and maternal hypertension on the incidence of idiopathic respiratory distress syndrome (IRDS). The occurrence of these complications was associated with a significant decrease in the incidence of IRDS only in infants with birthweights between 1,501 and 2,500 gm (37.4% in the no complications group versus 12.8% in the complications group; P less than .01) or gestational ages of 33 to 36 weeks (35.2% in the no complications group versus 13.1% in the complications group; P less than .01). In infants with birthweights of 1,500 gm or less or gestational ages of 32 weeks or less, the specific antecedent complications of pregnancy did not alter the incidence of IRDS. Rupture of the membranes for more than 72 hours had no greater effect on the incidence of IRDS than those lasting 24 to 72 hours.

An analysis of birthweights of 337 neonates in relation to history of maternal narcotic usage was undertaken. Mean birthweight of infants born to mothers abusing heroin during the pregnancy was 2,490 gm, an effect primarily of intrauterine growth retardation. Low mean birthweight (2,615 gm) was also seen in infants born to mothers who had abused heroin only prior to this pregnancy, and mothers who had used both heroin and methadone during the pregnancy (2,535 gm). Infants born to mothers on methadone maintenance during the pregnancy had significantly higher mean birthweights (2.961 gm), but lower than the control group (3,176 gm). A highly significant relationship was observed between maternal methadone dosage in the first trimester and birthweight, i.e., the higher the dosage, the larger the infant. Heroin causes fetal growth retardation, an effect which may persist beyond the period of addiction. Methadone may promote fetal growth in a dose-related fashion after maternal use of heroin.

OBJECTIVE: To define the relationships between neonatal opiate withdrawal and drug-related factors such as maternal methadone dosage, maternal and neonatal plasma levels, and rate of decline of methadone in neonatal plasma. METHODS: Twenty-one methadone-dependent women and their newborn infants were studied. Fourteen of the women used other illicit drugs. The severity of neonatal withdrawal was assessed with a standardized scoring system. Venous blood samples for methadone levels were collected from the mothers within 24 hours of delivery and from their newborns within 24 hours of birth and on day 3-4 of life. RESULTS: The maternal methadone dosage at delivery correlated significantly with the maternal plasma level drawn at 16 hours postpartum (r = 0.512, P < .05), and the maternal methadone level in turn correlated significantly with the neonatal plasma methadone level on day 1 of life (r = 0.545, P < .05). A positive correlation was found between the severity of central nervous system signs of withdrawal and the rate of decline of the neonatal plasma methadone level from day 1 to day 4 of life (r = 0.550, P < .05). CONCLUSION: This spectrum of relationships supports the concept that careful reduction of the maternal methadone dosage during pregnancy under intensive medical and psychosocial surveillance may benefit the drug-exposed new-born infant clinically.

Over 400,000 babies may be born annually following intrauterine exposure to opiates, stimulants and other illicit drugs. In addition, fetal exposure to alcohol and nicotine is common: of the 56 million women in the childbearing age range, 34 million are drinkers and 18 million are smokers. Published epidemiologic data suggest a strong association between Sudden Infant Death Syndrome (SIDS) and maternal smoking, a weaker association between SIDS and maternal opiate use, a still weaker association between SIDS and maternal cocaine use, and no association of SIDS and maternal alcohol use. Direct scientific links, however, between SIDS and exposure to any of these substances are still lacking. Because of reports in the medical literature and lay press linking maternal substance use to subsequent SIDS, specific drug-related counseling issues must be recognized by health professionals to provide effective intervention in the event of a SIDS death.

During the study years 1972--1974, 8 of 383 infants born to mothers with known narcotic dependency during pregnancy died unexpectedly within the first 4 mth of life; autopsies were compatible with the diagnosis of SIDS. This incidence of SIDS was 5.5 times that in our hospital populations (P < 0.001) and 8.7 times that of our borough within New York City (P < 0.001). Similar factors, such as sex ratio, age at time of death, and diurnal and seasonal variations suggest that narcotic-associated sudden death may be a relevant study model for sudden unexpected death in the general population. Intrauterine exposure to narcotics and its subsequent effect on central control of respiration in the young infant may be the underlying mechanism of drug related SIDS.

During the years 1971--1974, 230 infants born to drug-dependent women and 33 infants born to ex-addicts were studied. Heroin abuse declined while methadone usage increased during those years. Compared to heroin abuse, methadone maintenance treatment during pregnancy was associated with more consistent prenatal care, more normal fetal growth and reduced fetal mortality. Meconium staining of amniotic fluid was increased in the heroin and heroin-methadone groups; this was not associated, however, with an increase in meconium aspiration or a reduction in Apgar scores. Of special note was the equally severe intrauterine growth retardation of infants of former heroin addicts who were free of narcotic use during pregnancy. Neonatal withdrawal from methadone appeared to be more severe than from heroin, as judged by amount of medication required to control symptoms and duration of treatment. In all groups, central nervous system signs were the most common manifestations of withdrawal. Severity of withdrawal did not correlate with late pregnancy maternal methadone dosage. Neonatal seizures occurred in 1.5% of the heroin group and 10% of the methadone group. Discharge of an infant to a parent rather than to an alternate care-taker was more likely if the mother was enrolled in a methadone treatment program. Methadone maintenance programs appear to offer significant therapeutic benefits, balancing the untoward effects of the drug on the newborn infant.

The assessment and management of infants with intrauterine drug exposure poses significant challenges to the clinician. These challenges can be met most appropriately by relying on accurate history taking of maternal drug use complemented by the use of standardized assessments of the drug-exposed neonate and reliance on proved protocols of pharmacologic and nonpharmacologic management.

Methadone treatment during pregnancy offers overwhelming advantages compared with the less acceptable option of medical detoxification or the unacceptably dangerous option of leaving heroin-addicted women dependent on street drugs. General agreement exists that pregnancy offers a unique opportunity to bring women into medical, obstetric, and drug treatment. Methadone maintenance in the setting of comprehensive service provision during pregnancy reduces maternal morbidity and mortality and promotes fetal stability and growth. With an accumulated experience of over 25 years, methadone maintenance has been shown to be an invaluable and often an essential ingredient in bettering the health of women during pregnancy, in improving the outcomes of those pregnancies, and in offering opiate-addicted women a chance to improve both their lives and the lives of their families.

A solitary hepatic abscess was found at postmortem examination in a neonate who died at 25 days of age. Elevation of the right diaphragm was noted radiologically from the first day of life, suggesting congenital presence of the abscess. Recognition of the previously unsuspected association between hepatic abscess and congenital diaphragmatic elevation might have led to surgical intervention and have increased the infant's chance of survival.

Data on 178 term and 34 preterm infants born to methadone-maintained mothers were analyzed to assess the effects of neonatal opiate abstinence in infants of varying gestational ages. More mothers in the term group (79%) than in the preterm group (53%) had abused other drugs during pregnancy (p less than 0.001). Mean (+/- SD) gestational age was 39.5 weeks +/- 1.4 for term infants and 34.3 weeks +/- 2.6 for preterm infants. On the basis of a semiobjective symptom scoring scale, term infants had more severe abstinence symptoms and more prominent central nervous system manifestations than preterm infants. The severity of abstinence symptoms correlated with maternal methadone dosage in both term and preterm infants. Maternal multiple drug abuse (e.g., heroin, cocaine) did not influence severity of abstinence symptoms in either group. More term infants (145/178) than preterm infants (20/34) required treatment for these symptoms (p less than 0.005). In 13 of 178 term infants, compared with 1 of 34 preterm infants, abstinence-related seizures developed. Peak severity occurred 1 to 2 days earlier in term than in preterm infants. A less severe abstinence syndrome in preterm infants may be due to (1) developmental immaturity of either dendritic ramifications, specific opiate receptors, or neurotransmitter function, or (2) reduced total drug exposure during the intrauterine period.

Among 302 neonates passively addicted to narcotics, 18 had seizures that were attributed to withdrawal. Of those 18 infants, 10 were among the 127 infants exposed to methadone (7.8%), whereas only one of them was among the 83 infants exposed to heroin (1.2%). Generalized motor seizures and myoclonic jerks were the predominant convulsive manifestations. Paregoric was more effective than was diazepam in controlling and preventing these seizures once they occurred. Electroencephalograms were obtained on 13 neonates in the interictal period; 12 of these ECGs were normal. Three infants, two with myoclonic jerks, had paroxysmal brain wave activity at the time of the seizures.
