Prevalência da exposição pré-natal à cocaína em uma amostra de recém-nascidos de um hospital geral universitário

OBJECTIVE: to assess the prevalence of prenatal exposure to cocaine in a sample of newborns using two methods: fluorescence polarization immunoassay and interview with the mother. METHODS: this cross-sectional study was carried out in a university teaching hospital. The population included all live births between March 23, 1999 and June 01, 1999 (n=847). Exposure was determined by a benzoylecgonine-positive meconium specimen and/or by a positive interview with the mother. RESULTS: the prevalence of prenatal exposure to cocaine in this sample was 2.4% (16 cases) according to the interviews, and 3.4% (25 cases) according to the meconium analysis. A rate of 4.6% (34 cases) was found when both methods were associated. CONCLUSIONS: we observed that the meconium test was more effective than the maternal interview for the diagnosis of prenatal exposure to cocaine. The meconium analysis enhanced diagnostic chances by 53.4%, compared to 26% in the case of maternal interview.

Prenatal exposure to cocaine: review of the neurobehavioral effects

OBJECTIVE: To study prenatal cocaine exposure, emphasizing its behavioral effects. METHODS: Literature review of the last 15 years, through Medline and direct search. RESULTS AND CONCLUSIONS: According to the literature, the incidence of prenatal cocaine exposure is up to 15.5%, and its effects on the newborn are particularly on the development of the nervous system. Pediatricians and sub-specialists must know the consequences of such exposure in order to diagnose and affect the prognosis of these children.

Socio-demographic and clinical characteristics of pregnant and puerperal crack-cocaine using women: preliminary data

Background The literature provides several studies on the effects of cocaine when exposed to the fetus. However, the majority of these data comes from animal models. Objective The objective of this study is to present socio-demographic and clinical data in crack-cocaine using pregnant women and their babies, as compared to non-users. Methods Cross-sectional study, comprised by 56 dyads of crack-cocaine using mothers-babies and 89 control dyads. In addition to the socio-demographic data and the babies’ information, data collection was based on ABIPEMI for socioeconomic level, WAIS for IQ, MINI for psychopathology and ASSIST for drug use. Results Most crack users, in comparison to non-users, did not have a partner (10.52% vs 4.4%, P = 0.001) and presented lower IQ (78.15, +/-8.07 vs 84.27 +/- 9.87; P = 0.002). The prevalence of antisocial personality disorder and suicide risk in users was higher than in non-users (24.44% vs none, P < 0.001; 28.26% vs 10.46% P = 0.01). Most of the users did not participate in prenatal care (75%). The babies that the crack-cocaine using mothers gave birth to weighed significantly less than the controls (2.858 g vs 3.240 g, P = 0.002). Discussion Users had a higher degree of psychopathology and lower attendance in prenatal care. There was an overlap of adverse factors, both for exposed mothers and babies. The sum of these vulnerabilities could result in significant harm to the developing infant.
