Neonatal manifestations of maternal phencyclidine exposure.

The purpose of this study was to determine the effects of maternal phencyclidine use on the fetus. Ninety-four neonates with maternal phencyclidine exposure were compared with 94 controls. Maternal phencyclidine use was assessed by questionnaire and repeated urine testing. Mothers of study and control patients were matched for demographic characteristics. Infants were assessed between 24-72 hours postnatally by a single examiner blind to the maternal history. The results showed that study infants had a mean of 5.02 +/- 2.93 abnormalities while controls had a mean of 4.13 +/- 2.65 abnormalities (p less than 0.01). Furthermore, study infants were more likely than controls to have poor attention, hypertonia, and depressed neonatal reflexes (p less than 0.05). The contribution of seven drug classes to the total number of abnormalities was assessed using stepwise multiple regression. Only phencyclidine accounted for a significant proportion of the variance (f = 4.38; p less than 0.05). The results of this study suggest that maternal phencyclidine use may lead to abnormal neonatal neurologic findings and behavior.

Measurement of the amino acid metabolite of phencyclidine by selected ion monitoring.

A technique is described for the extraction and quantitation of the pentanoic acid metabolite of phencyclidine by gas chromatography/mass spectrometry. This compound was measured in urine samples from asymptomatic pregnant patients who used phencyclidine (PCP) and their neonates. The technique is sensitive to 25 ng ml-1 urine and standard curves were linear at 25-2000 ng ml-1. Levels in samples from asymptomatic patients were 27-1388 ng ml-1. Results suggest that the pentanoic acid metabolite could be considered as a screening marker for occasional PCP use.

Phencyclidine use during pregnancy.

Phencyclidine, a frequently abused drug, has been shown to cross the placenta and may cause harmful effects in the fetus. Therefore, a prospective study was undertaken to determine the extent of phencyclidine use during pregnancy. Two thousand three hundred twenty-seven pregnant women were screened for phencyclidine use by questionnaire and enzyme-mediated immunoassay technique urine testing. Nineteen women were identified as using phencyclidine during pregnancy and 149 were past users. Women with a history of phencyclidine use were compared with a population sample of nonusers. Phencyclidine users were more likely to be white; they were also younger and of lesser parity than nonusers. The majority had a history of multiple drug abuse. Although 7.3% of the population gave a history of phencyclidine use and 0.8% were found to use the drug during pregnancy, these figures are believed to underestimate the problem.

Premature delivery and subsequent reproduction.

To examine the relationship between premature delivery and subsequent reproductive behavior, we attempted to trace 100 mothers four years after the birth of a surviving preterm or term infant. Seventy mothers were successfully traced. Maternal age, ethnicity, gravidity, parity, religion, and socioeconomic status, and the sex, birthweight, gestational age, mode of delivery, and hospital days of the index infant were jointly related to three outcome measures: occurrence of subsequent pregnancy, and, among those who again became pregnant, pregnancy interval and number of subsequent children. Among women who had one or more subsequent births during the follow-up period, those whose index infants were of lower gestational age had fewer subsequent births (r = 0.602, df = 32, p less than 0.011). No other variables, including cesarean birth, were significantly related to later reproductive behavior. These findings indicate that the birth of a premature infant may have a significant effect of decreasing or delaying subsequent reproduction. Through confirmatory studies are needed, awareness of this relationship may help obstetric perinatologists and neonatologists sensitively discuss plans for contraception and further childbearing with women who have experienced the stress of the birth of a premature infant.

Propoxyphene and acetaminophen. Possible effects on the fetus.

Propoxyphene (Darvon) and acetaminophen (Tylenol) are widely prescribed analgesic agents. Both can cross the placenta, and propoxyphene can produce serious withdrawal symptoms in newborns. Neither propoxyphene nor acetaminophen is considered a teratogen, yet, three malformed infants who were antenatally exposed to propoxyphene have previously been reported. We report a fourth case of an infant, with withdrawal symptoms and cranial-facial and digital malformations, born to a women who used propoxyphene and acetaminophen throughout her pregnancy. We suggest that possibility that the antepartum use of propoxyphene and acetaminophen, in combination, may be teratogenic.

Maternal alcohol use and infant development.

A prospective controlled study of the effect of fetal alcohol on infant development was performed. Twelve infants were identified as possibly having fetal alcohol effects based on the maternal history of alcohol abuse and the neonatal physical examination. Physical characteristics, growth, and development of these infants were compared with those of 12 control infants at birth and at a mean age of 12 months; control infants were matched for gestational age, sex, and race. Data were evaluated by descriptive statistics and analysis of differences between matched pairs of study and control infants. The results showed a significant correlation between the history of heavy antenatal maternal alcohol use and delayed mental and motor development, physical abnormalities, and growth retardation in the infants. This study suggests that infants with fetal alcohol effects can be correctly classified at birth and their outcome accurately predicted.

Zinc status of pregnant alcoholic women: a determinant of fetal outcome.

The zinc status of 25 alcoholic and 25 non-alcoholic pregnant women was measured and correlated with fetal outcome. The volume index of alcohol consumption and the Michigan Alcoholic Screening Test were used to define alcoholic women. The alcoholic women had significantly lower plasma-zinc levels that the non-alcoholic women (50.7 versus 72.2 micrograms/dl). Fetal cord-plasma zinc levels were also lower in the offspring of alcoholic women (65.5 versus 81.3 micrograms/dl). Manifestation of fetal dysmorphogenesis appears to relate to zinc status.

Abnormality of chromosome 16 and its phenotypic expression.

An abnormality of chromosome 16 in which there is extra genetic material present on the short arm (46,XY, 16p+) has been identified. This chromosomal aberration was associated with multiple congenital anomalies, including mid-facial hypoplasia, arthrogryposis, and mental retardation. On the basis of the cytogenetic appearance and the phenotype of the patient, this may represent a partial 16 trisomy. Unlike most abnormalities of chromosome 16, this syndrome was compatible with life.

Angel dust: possible effects on the fetus.

A case report of an infant whose mother used phencyclidine (PCP, "angel dust") during pregnancy is presented. As a neonate, the infant showed abnormal behavior and an unusual appearance, and later, spastic quadriparesis. Based on previous animal studies, it is likely that this infant had prolonged exposure to PCP as a fetus. His abnormal neonatal behavior was consistent with previously reported effects of this drug. The relationship between his exposure to PCP and his dysmorphology and spasticity remains speculative. It is suggested that clinicians be alert to further cases of these associations.
