Abstract
The purpose of this article was to present a review of the effects of alcohol consumption by pregnant mothers on their newborn. Definitions, prevalence, pathophysiology, clinical features, diagnostic criteria, follow-up, treatment and prevention were discussed. A search was performed in Medline, LILACS, and SciELO databases using the following terms: "fetus", "newborn", "pregnant woman", "alcohol", "alcoholism", "fetal alcohol syndrome", and "alcohol-related disorders". Portuguese and English articles published from 2000 to 2009 were reviewed. The effects of alcohol consumed by pregnant women on newborns are extremely serious and occur frequently; it is a major issue in Public Health worldwide. Fetal alcohol spectrum disorders cause harm to individuals, their families, and the entire society. Nevertheless, diagnostic difficulties and inexperience of healthcare professionals result in such damage, being remembered rarely or even remaining uncovered. Alcohol-related injury to the fetus is fully avoidable; all it takes is for women not to drink alcoholic beverages during pregnancy. Therefore, detecting women who consume alcohol during pregnancy is paramount, as are specific programs to educate people about the consequences of alcohol use during pregnancy and breastfeeding.

Abstract
OBJECTIVE To identify the presence of fetal alcohol syndrome, other alcohol-related congenital defects, and/or neurodevelopment disorders in newborns of mothers who consumed alcohol during gestation. METHODS In a public maternity in the city of São Paulo, 1,964 puerperal women were interviewed and 654 had consumed alcohol at some point during gestation. The newborns were clinically and laboratorially examined in order to identify the occurrence of fetal alcohol syndrome, congenital defects or neurodevelopment disorders related to alcohol. RESULTS Three children were found with fetal alcohol syndrome (1.5/1,000 live births), 6 with congenital defects related to alcohol (3.0/1,000 live births), and 67 with developmental disorders related to alcohol (34.1/1,000 live births). The congenital malformations found in these children were thin or absent corpus callosum, brain cyst, asymmetry of the cerebral ventricles, meningomyelocele, cleft lip, anteverted nose, low-set ears, megaureter, hydronephrosis, polydactyly, congenital clubfoot, aphalangia of the toes, cryptorchidism, and hypospadia. CONCLUSION Newborns of mothers who consumed alcohol may have congenital malformations of various organs and systems, and early diagnosis is fundamental for a probable and occasional more effective resolution and progress.

Abstract
The objective of this study was to estimate the aggregate burden of maternal binge drinking on preterm birth (PTB) and low birth weight (LBW) across American sociodemographic groups in 2008. To estimate the aggregate burden of maternal binge drinking on preterm birth (PTB) and low birth weight (LBW) across American sociodemographic groups in 2008. A simulation model was developed to estimate the number of PTB and LBW cases due to maternal binge drinking. Data inputs for the model included number of births and rates of preterm and LBW from the National Center for Health Statistics; female population by childbearing age groups from the U.S. Census; increased relative risks of preterm and LBW deliveries due to maternal binge drinking extracted from the literature; and adjusted prevalence of binge drinking among pregnant women estimated in a multivariate logistic regression model using Behavioral Risk Factor Surveillance System survey. The most conservative estimates attributed maternal binge drinking to 8,701 (95% CI: 7,804-9,598) PTBs (1.75% of all PTBs) and 5,627 (95% CI 5,121-6,133) LBW deliveries in 2008, with 3,708 (95% CI: 3,375-4,041) cases of both PTB and LBW. The estimated rate of PTB due to maternal binge drinking was 1.57% among all PTBs to White women, 0.69% among Black women, 3.31% among Hispanic women, and 2.35% among other races. Compared to other age groups, women ages 40-44 had the highest adjusted binge drinking rate and highest PTB rate due to maternal binge drinking (4.33%). Maternal binge drinking contributed significantly to PTB and LBW differentially across sociodemographic groups.

Abstract
Background Alcohol consumption during pregnancy can result in a range of adverse pregnancy outcomes including Fetal Alcohol Spectrum Disorders (FASD). Risky drinking among Russian women constitutes a significant risk for alcohol-exposed pregnancies (AEP). Russian women report that obstetrics and gynecology (OB/GYN) physicians are the most important source of information about alcohol consumption during pregnancy and developing effective prevention interventions by OB/GYNs is indicated. This is the first study focused on implementation of an AEP prevention intervention at women’s clinics in Russia. Method The paper describes the intervention protocol and addresses questions about the feasibility of a brief FASD prevention intervention delivered by OB/GYNs at women’s clinics in Russia. Brief physician intervention guidelines and two evidence-based FASD prevention interventions were utilized to design a brief dual-focused physician intervention (DFBPI) appropriate to Russian OB/GYN care. The questions answered were whether trained OB/GYN physicians could deliver DFBPI during women’s routine clinic visits, whether they maintained skills over time in clinical settings, and which specific intervention components were better maintained. Data were collected as part of a larger study aimed at evaluating effectiveness of DFBPI in reducing AEP risk in non-pregnant women. Methods of monitoring the intervention delivery included fidelity check lists (FCL) with the key components of the intervention completed by physicians and patients and live and audio taped observations of intervention sessions. Physicians (N = 23) and women (N = 372) independently completed FCL, and 78 audiotapes were coded. Results The differences between women’s and physicians’ reports on individual items were not significant. Although the majority of physician and patient reports were consistent (N = 305), a discrepancy existed between the reports in 57 cases. Women reported more intervention components missing compared to physicians (p < 0.001). Discussing barriers was the most difficult component for physicians to implement, and OB/GYN demonstrated difficulties in discussing contraception methods. Conclusions The results supported the feasibility of the DFBPI in Russia. OB/GYN physicians trained in the DFBPI, monitored, and supported were able to implement and maintain skills during the study. In addition to the alcohol focus, DFBPI training needs to have a sufficient component to improve physicians’ skills in discussing contraception use.

Abstract
BACKGROUND Fetal alcohol spectrum disorders result from heavy prenatal alcohol exposure and are characterized, in some cases, by central nervous system anomalies and cognitive impairment. Regional patterns of neuroanatomical abnormalities suggest that alcohol exerts selective damage on the developing fetal brain. This study assessed brain-behavior relationships in a sample of youth with histories of heavy prenatal alcohol exposure. The aim was to characterize how structural brain alterations observed in our previous studies relate to cognitive deficits commonly reported in individuals with histories of heavy prenatal alcohol exposure. METHODS Twenty-one youth (mean age 13 years) with histories of heavy prenatal alcohol exposure and 7 nonexposed healthy comparison subjects underwent structural magnetic resonance imaging and neurobehavioral testing. Regional brain volumes within the alcohol-exposed group were correlated with neuropsychological measures of cognitive control and verbal learning/recall, as these aspects of cognition have previously been shown to be vulnerable to alcohol teratogenesis. RESULTS Between-group effect sizes revealed moderate to large cognitive performance and brain volume decrements in alcohol-exposed subjects, compared with typically developing peers. Within the alcohol-exposed group, volume of the caudate nuclei was the most consistent predictor of neuropsychological performance, after controlling for potentially confounding variables including total brain volume, IQ, and age. CONCLUSIONS These data are consistent with previous research associating gestational alcohol exposure with structural and functional changes of the caudate nucleus. Our findings extend this previous work by demonstrating that volume reductions of the caudate have behavioral relevance for this population, in relation to cognitive control and verbal learning and recall abilities.

Abstract
ABSTRACT Objective: To prepare percentile curves for measurements of palpebral fissure and the greatest width of the vermilion border of the upper lip in newborns at a public maternity ward in the City of São Paulo. Methods: A descriptive cross-sectional study was carried out from August 2006 to January 2008. In the first 24 to 72 hours of life, the palpebral fissure and the greatest width of the vermilion border of the upper lip were measured in 1,964 newborns with gestational ages from 25 to 43 weeks. Percentile curves corresponding to these measurements were prepared according to gestational age. Results: The average measurement of palpebral fissure was 1.98 cm, ranging from 0.80 to 3.00 cm, standard deviation ± 0.24 cm. The average measurement of the width of the vermilion border of the upper lip was 0.51 cm, ranging from 0.20 to 0.90 cm, standard deviation ± 0.11 cm. These measurements allowed designing the percentile curves (10th, 50th, and 90th) relative to gestational age. Conclusions: Measurement curves of palpebral fissure and of the greatest width of the vermilion border of the upper lip may be useful to evaluate the presence of facial dimorphism in newborns.

Abstract
BACKGROUND Children with fetal alcohol spectrum disorders (FASD) have deficits in verbal learning and recall. However, the specificity of these deficits has not been adequately tested. In the current study, verbal learning and memory performance of children with heavy prenatal alcohol exposure was compared to children with attention-deficit/hyperactivity disorder (ADHD), a disorder commonly seen in alcohol-exposed children. METHODS Performance on the California Verbal Learning Test-Children's Version (CVLT-C) was examined in 3 groups of children (N=22/group): (i) heavy prenatal alcohol exposure and ADHD (ALC), (ii) nonexposed with ADHD (ADHD), and (iii) nonexposed typically developing (CON). Groups were matched on age, sex, race, ethnicity, handedness, and socioeconomic status (SES). RESULTS Group differences were noted on learning trials (CON >ADHD> ALC). On the delayed recall trial, CON children performed better than both clinical groups, who did not differ from each other. Children in the ALC group demonstrated poorer recognition than children in the CON and ADHD groups, who did not differ from each other. Marginally significant group differences were noted on retention of previously learned material. Post hoc analyses indicated that ADHD children showed worse retention relative to the CON group, whereas retention in the ALC children remained intact. CONCLUSIONS These data suggest that children with heavy prenatal alcohol exposure and nonexposed children with ADHD show differential patterns of deficit on the CVLT-C. Performance of alcohol-exposed children reflects inefficient encoding of verbal material, whereas performance of the ADHD group may be better characterized by a deficit in retrieval of learned material. Differences noted between clinical groups add to a growing neurobehavioral profile of FASD that may aid in differential diagnosis.

Abstract
Conceptualizations of risks related to women's alcohol use during pregnancy, and the attendant response to preventing fetal alcohol spectrum disorder (FASD), are examined in six countries: the United States, Canada, the United Kingdom, Uganda, Uruguay, and China. Considerable differences were found in how risks were conceptualized across countries and in contextual factors that influence research, prevention, and intervention efforts. Differences in conceptualizations were also apparent within countries. Differences also existed in the degree to which the issue of drinking during pregnancy has been minimized or amplified and in whether and how responses are linked to treatment or other public health interventions.

Abstract
Created forty years ago, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) has played a major role in the great strides made in the understanding, treatment, prevention, and public acceptance of alcohol-use disorders. Throughout most of U.S. history "habitual drunkenness" was viewed as a problem of moral degeneracy or character flaw inherent in the individual. However, the wealth of scientific evidence amassed throughout NIAAA's history has established alcoholism as a medical condition, that is, as a disease for which affected individuals should feel no shame or be treated with disdain. We look at the developments in alcohol epidemiology, typology, etiology, prevention, and treatment research over the past 40 years. We also discuss how NIAAA addresses alcohol disorders from a life-course framework, affecting all stages of the lifespan, from fetus through child, adolescent, and young adult, to midlife/senior adult, with each stage involving different risks, consequences, prevention efforts, and treatment strategies.

Abstract
Prenatal alcohol exposure (PAE) alters adult neurogenesis and the neurogenic response to stress in male rats. As the effects of stress on neurogenesis are sexually dimorphic, the present study investigated the effects of PAE on adult hippocampal neurogenesis under both nonstressed and stressed conditions in female rats. Pregnant females were assigned to one of three prenatal treatments: (1) alcohol (PAE)-liquid alcohol (ethanol) diet ad libitum (36% ethanol-derived calories); (2) pair-fed-isocaloric liquid diet, with maltose-dextrin substituted for ethanol, in the amount consumed by a PAE partner (g/kg body wt/day of gestation); and (3) control-lab chow ad libitum. Female offspring were assigned to either nonstressed (undisturbed) or stressed (repeated restraint stress for 9 days) conditions. On day 10, all rats were injected with bromodeoxyuridine (BrdU) and perfused either 24 hours (cell proliferation) or 3 weeks (cell survival) later. We found that PAE did not significantly alter cell proliferation or survival, whereas females from the pair-fed condition exhibited elevated levels of cell survival compared to control females. Importantly, however, the proportion of both new neurons and new glial cells in the hippocampal dentate gyrus was reduced in PAE compared to control females. Exposure to stress did not alter neurogenesis in any of the prenatal treatment groups. In summary, compared to females from the control condition, prenatal dietary restriction enhanced the survival of new neurons, whereas PAE altered the differentiation of newly produced cells in the adult dentate gyrus. Alterations in hippocampal neurogenesis following PAE may contribute to learning and memory deficits seen in individuals with fetal alcohol spectrum disorders.

Abstract
BACKGROUND A primary goal of recent research is the development of neurobehavioral profiles that specifically define fetal alcohol spectrum disorders (FASD), which may assist differential diagnosis or improve treatment. In the current study, we define a preliminary profile using neuropsychological data from a multisite study. METHODS Data were collected using a broad neurobehavioral protocol from 2 sites of a multisite study of FASD. Subjects were children with heavy prenatal alcohol exposure and unexposed controls. The alcohol-exposed group included children with and without fetal alcohol syndrome (FAS). From 547 neuropsychological variables, 22 variables were selected for analysis based on their ability to distinguish children with heavy prenatal alcohol exposure from nonexposed controls. These data were analyzed using latent profile analysis (LPA). RESULTS The results indicated that a 2-class model best fit the data. The resulting profile was successful at distinguishing subjects with FAS from nonexposed controls without FAS with 92% overall accuracy; 87.8% of FAS cases and 95.7% of controls were correctly classified. The same analysis was repeated with children with heavy prenatal alcohol exposure but without FAS and nonexposed controls with similar results. The overall accuracy was 84.7%; 68.4% of alcohol-exposed cases and 95% of controls were correctly classified. In both analyses, the profile based on neuropsychological variables was more successful at distinguishing the groups than was IQ alone. CONCLUSIONS We used data from 2 sites of a multisite study and a broad neuropsychological test battery to determine a profile that could be used to accurately identify children affected by prenatal alcohol exposure. Results indicated that measures of executive function and spatial processing are especially sensitive to prenatal alcohol exposure.

Abstract
BACKGROUND Adaptive behavior, the ability to respond successfully to everyday demands, may be especially sensitive to the effects of heavy prenatal alcohol exposure. Similar adaptive dysfunction is common in other developmental disorders including attention-deficit/hyperactivity disorder (ADHD). ADHD is frequently present in alcohol-exposed children and this overlap in clinical presentation makes identification of alcohol-exposed children difficult. Direct comparison of children with prenatal alcohol exposure and ADHD may yield distinct patterns of cognitive and behavioral performance and add to growing knowledge of the neuropsychological and behavioral profile of prenatal alcohol exposure. Therefore, the aim of the current study was to compare adaptive behavior in children with histories of heavy prenatal alcohol exposure (ALC), nonexposed children with ADHD (ADHD), and typically developing controls (CON). METHODS Sixty-five children (ALC = 22, ADHD = 23, CON = 20) were selected from a larger ongoing study of the behavioral teratogenicity of alcohol. Alcohol-exposed and control participants were selected to match the ADHD subjects on age, sex, socioeconomic status, and race/ethnicity. Caregivers were administered the Vineland Adaptive Behavior Scales, a semi-structured interview, and were asked to rate their child's behavior on 3 domains of adaptive function. Data were analyzed using regression techniques. RESULTS Relative to controls, children in both the ALC and ADHD groups showed adaptive behavior deficits on all 3 domains and children in the ALC group were significantly more impaired than the ADHD group on the daily living skills domain. Within the ALC group, socialization standard scores were lower at older ages. This negative relationship between age and standard scores in the ALC group was also observed on the communication domain, a finding not previously reported. CONCLUSIONS This study suggests that both children with prenatal alcohol exposure and children with ADHD show impairments in adaptive function relative to controls, but that the pattern of impairment differs between these clinical groups. Adaptive ability in children with prenatal alcohol exposure is characterized by an arrest in development, as evidenced by a lack of improvement with age in socialization and communication scores. In contrast, children with ADHD exhibit a developmental delay in adaptive ability as their scores continued to improve with age, albeit not to the level of control children. Continued research focused on elucidating the patterns of deficits that exist in alcohol-exposed children ultimately will lead to improved differential diagnosis and effective interventions.

Abstract
BACKGROUND Children with heavy prenatal alcohol exposure have documented impairments in executive functioning (EF). One component of EF, concept formation, has not been well studied in this group. METHODS Children (8 to 18 years) with histories of heavy prenatal alcohol exposure, with and without fetal alcohol syndrome (FAS), were compared to typically developing controls on 2 measures of concept formation and conceptual set shifting: the Wisconsin Card Sorting Test and the Card Sorting Test from the Delis-Kaplan Executive Functioning System. In addition to between-group comparisons, performance relative to overall intellectual functioning was examined. RESULTS Children with histories of heavy prenatal alcohol exposure showed impairment on both tests of concept formation compared to non-exposed controls. These deficits included difficulty generating and verbalizing concepts, increased error rates and perseverative responses, and poorer response to feedback. However, in comparison to controls, alcohol-exposed children performed better on measures of concept formation than predicted by their overall IQ scores. Exploratory analyses suggest that this may be due to differences in how the measures relate at different IQ levels and may not be specific to prenatal alcohol exposure. CONCLUSIONS Deficits in concept formation and conceptual set shifting were observed in alcohol-exposed children with or without the diagnosis of FAS and in the absence of mental retardation. These deficits likely impact problem solving skills and adaptive functioning and have implications for therapeutic interventions in this population.

Abstract
Children with either fetal alcohol spectrum disorder (FASD) or attention-deficit/hyperactivity disorder (ADHD) display deficits in attention and executive function (EF) and differential diagnosis of these two clinical groups may be difficult, especially when information about prenatal alcohol exposure is unavailable. The current study compared EF performance of three groups: children with heavy prenatal alcohol exposure (ALC); nonexposed children with attention-deficit/hyperactivity disorder (ADHD); and typically developing controls (CON). Both clinical groups met diagnostic criteria for ADHD. The EF tasks used were the Wisconsin Card Sorting Test (WCST), the Controlled Oral Word Association Test (COWAT), and the Trail Making Test (TMT). Results indicated different patterns of deficit; both clinical groups displayed deficits on the WCST and a relative weakness on letter versus category fluency. Only the ALC group displayed overall deficits on letter fluency and a relative weakness on TMT-B versus TMT-A. In addition, WCST performance was significantly lower than expected based on IQ in the ADHD group and significantly higher than expected in the ALC group. These results, which indicate that, although EF deficits occurred in both clinical groups, the degree and pattern of deficit differed between the ALC and ADHD groups, may improve differential diagnosis.

Abstract
BACKGROUND Alcohol use during pregnancy can result in a continuum of effects including growth deficits, dysmorphology and/or complex patterns of behavioural and cognitive difficulties that influence an individual's functioning throughout their lifespan. We conducted a systematic review to identify research-based interventions for children and youth with a Fetal Alcohol Spectrum Disorder and areas for future study. METHODS We identified the substantive literature by searching 40 peer-reviewed and 23 grey literature databases, as well as reference lists. We hand-searched eight relevant journals, and undertook a systematic search of Internet sites and review of reports and documents received from key stakeholders. Two reviewers independently assessed eligibility and quality, and extracted data. Given the small number of studies that met all inclusion criteria, both experimental and quasi-experimental studies were included. RESULTS Ten intervention studies were identified, of which three were experimental or quasi-experimental, and four were non-experimental. Despite multiple attempts, three studies (two in foreign languages and one unpublished) could not be acquired. A meta-analysis could not be undertaken because the included studies examined different interventions or outcomes. Interventions targeted in the included studies were as follows: (i) psychostimulant medications (methyphenidate, pemoline and dextroamphetamine); and (ii) Cognitive Control Therapy. The identified studies were limited by very small sample sizes and weak designs. CONCLUSION There is limited scientific evidence upon which to draw recommendations regarding efficacious interventions for children and youth with a Fetal Alcohol Spectrum Disorder. Clinicians, researchers, service providers, educators, policy makers, affected children and youth and their families, and others need to urgently collaborate to develop a comprehensive research agenda for this population.

Abstract
OBJECTIVE This study compared the prevalence of psychopathological conditions in children with heavy prenatal alcohol exposure (N = 39) and nonexposed, typically developing peers (N = 30), matched with respect to age, gender, and socioeconomic status. METHODS Caregivers were interviewed with either the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime Version, or the Computerized Diagnostic Interview Schedule for Children, Version IV. Statistical resampling methods were used to create 95% confidence intervals for the difference between the proportions of children with psychopathological conditions in the exposed and control groups. RESULTS Group differences were seen in the attention-deficit/hyperactivity disorder, depressive disorders, oppositional defiant disorder, conduct disorder, and specific phobia outcome categories. The group difference in the attention-deficit/hyperactivity disorder category was by far the largest effect observed. CONCLUSIONS These results suggest that fetal alcohol exposure should be considered a possible factor in the pathogenesis of childhood psychiatric disorders. These data provide clinically relevant information about the mental health problems that children with fetal alcohol exposure are likely to face.

Abstract
BACKGROUND There has been considerable effort expended on defining neurobehavioral characteristics of children with fetal alcohol spectrum disorders (FASD). Children with FASD display a range of cognitive deficits and behavioral problems. In this article, we report on the neurobehavioral characteristics of children with FASD in selected communities in Italy. It was expected that both inattentive and hyperactive/impulsive characteristics would discriminate children with FASD from controls and that the groups would also differ on intellectual functioning, language comprehension, and academic skills. METHODS Eighty-two children, 22 diagnosed with FASD and 60 control children, participated in this study. The children were administered tests of nonverbal reasoning, language comprehension, academic achievement, and behavior. RESULTS On tests of nonverbal reasoning and language comprehension, the FASD group earned lower scores than did controls. Moreover, on a test of academic achievement the FASD group scored lower. When comparing these 2 groups on disruptive behavioral symptomatology, similar results were obtained, the FASD group showing greater attentional difficulties and hyperactivity/impulsivity behaviors and more overall behavioral problems. Stepwise logistic regression analysis showed that a model containing inattention and error scores on the language comprehension task correctly classified 85% of the participants. Compared with the control group, a significantly greater proportion of children with FASD met the Diagnostic and Statistical Manual of Mental Disorders-fourth edition (DSM-IV) criteria of ADD, inattentive type, as reported by teachers. In contrast, hyperactive symptoms among children with FASD were comparable with the control group. Teachers rated children with FASD as having more inattentive behaviors and as performing lower in academic skills than controls. The association between reported hyperactivity symptoms and achievement scores was nonsignificant for both language and math scores, suggesting that it is not the hyperactivity causing problems, but the child's inattention. CONCLUSIONS This research indicates that a nonclinic-referred sample of Italian children with FASD display a profile of neurobehavioral functioning consistent with that reported by other researchers. Furthermore, the neurobehavioral characteristic most identified with children diagnosed with FASD was inattention followed by hyperactivity.

Abstract
BACKGROUND Alcohol use in Russia is among the highest in the world. Over 600,000 children reside in institutional care in Russia, most of them in baby homes and orphanages. The actual prevalence of fetal alcohol spectrum disorders (FASD) among these children is unknown. Therefore, we performed a systematic survey of phenotypic features associated with prenatal alcohol exposure among institutionalized Russian children and related these findings to their growth, development, medical, and social histories. METHODS Phenotypic screening was conducted of all 234 baby home residents in the Murmansk region of Russia (mean age 21+12.6 months). Phenotypic expression scores were devised based on facial dysmorphology and other readily observable physical findings. Growth measurements from birth, time of placement in the baby home, and at present were analyzed. In addition, the charts of 64% of the children were randomly selected for retrospective review. Information collected included maternal, medical, developmental, and social histories. RESULTS Thirteen percent of children had facial phenotype scores highly compatible with prenatal alcohol exposure and 45% had intermediate facial phenotype scores. These scores correlated with maternal gravidity and age. At least 40% of mothers in whom history was available ingested alcohol during pregnancy; some also used illicit drugs and tobacco. Z scores for growth measurements corresponded to phenotypic score, as did the degree of developmental delay. Children with no or mild delay had significantly lower phenotypic scores than those with moderate or severe delay (p = 0.04); more than 70% of children with high phenotypic scores were moderately or severely delayed. CONCLUSIONS More than half of residents of the baby homes in Murmansk, Russia, have intermediate (45%) or high (13%) phenotypic expression scores suggesting prenatal exposure to alcohol. Despite good physical care, stable daily routine, availability of well-trained specialists, and access to medical care, these vulnerable children show significant growth and developmental delays compared with their institutionalized peers.

Abstract
BACKGROUND Among individuals who use alcohol and tobacco products, pregnant women represent a unique subpopulation that generates a greater concern because of the toxic effects of alcohol and nicotine (from cigarettes and tobacco products) on the health of both the pregnant woman and her fetus. Therefore, it is imperative to understand the interactive effects of these two substances on the fetus. Previously, we found that concurrent exposure to alcohol and nicotine did not result in the loss of greater numbers of Purkinje cells compared with each drug treatment alone, possibly as a result of a nicotine-mediated decline in peak blood alcohol concentration (BAC). The present study tested the validity of this hypothesis. METHODS On postnatal day (PD) 4, Sprague-Dawley rat pups were assigned to five groups, GC (no alcohol [ALC], no nicotine [NIC]), ALC (4 g/kg/day), NIC (6 mg/kg/day), ALC/NIC (ALC and NIC given concurrently), or ALC-NIC (NIC administered 6 hr after ALC exposure). These rat pups were reared in an artificial-rearing apparatus from PDs 4 to 9, and the cerebellar tissues were obtained on PD 10. The total number of cerebellar Purkinje cells in the vermis was estimated using stereological methods. RESULTS The results showed that alcohol significantly reduced Purkinje cell numbers. The coexposure of alcohol and nicotine did not lead to further reduction in Purkinje cell number regardless of administration method, concurrent or sequential. However, alcohol and nicotine administered concurrently but not sequentially significantly lowered the BAC. CONCLUSION These findings suggest that the lack of increased Purkinje cell loss after the coexposure of alcohol and nicotine is independent of nicotine's ability to lower the BAC. An alternative hypothesis might be that alcohol and nicotine target the same subpopulation of Purkinje cells; therefore, no additional Purkinje cells were lost from the coexposure of these two drugs.

Abstract
Clinical reports on monozygotic and dizygotic twins provided the initial evidence for the involvement of genetic factors in risk vulnerability for fetal alcohol spectrum disorders (FASD) including fetal alcohol syndrome (FAS). Research with selectively bred and inbred rodents, genetic crosses of these lines and strains, and embryo culture studies have further clarified the role of both maternal and fetal genetics in the development of FASD. Research to identify specific polymorphisms contributing to FASD is still at an early stage. To date, polymorphisms of only one of the genes for the alcohol dehydrogenase enzyme family, the ADH1B, have been demonstrated to contribute to FASD vulnerability. In comparison with ADH1B*1, both maternal and fetal ADH1B*2 have been shown to reduce risk for FAS in a mixed ancestry South African population. ADH1B*3 appears to afford protection for FASD outcomes in African-American populations. Other candidate genes should be examined with respect to FASD risk, including those for the enzymes of serotonin metabolism, in particular the serotonin transporter. By its very nature, alcohol teratogenesis is the expression of the interaction of genes with environment. The study of genetic factors in FASD falls within the new field of ecogenetics. Understanding of the array of genetic factors in FASD will be enhanced by future genetic investigations, including case-control, family association, and linkage studies.

Abstract
Developmental alcohol exposure adversely influences the developing brain. Alcohol exposure during rapid brain growth causes cell loss, alters connections between brain regions, and lowers the production of biological substances responsible for the communication among neurons. It is reasonable to suggest that alcohol may adversely affect the development of suprachiasmatic nuclei (SCN), the master circadian pacemaker. Multiple research reports suggest that abnormalities in circadian rhythms are involved in the etiopathogenesis of seasonal affective disorder (SAD), a syndrome in which depression develops during autumn or winter and remits the following spring or summer. Several lines of evidence suggest that changes in the circadian system are also involved in the development of nonseasonal mood disorders, such as major depression and bipolar disorder. Thus, developmental alcohol exposure produces subtle abnormalities in circadian rhythms that may contribute to the development of seasonal and nonseasonal mood disorders. Pharmacological, psychological, and light treatments of mood disorders have multiple effects on circadian function. The state of the circadian system may affect a response to treatment. Circadian rhythms have been reported for neurotransmitters, receptors, enzymes, and the second messenger system in the brain that are involved in the effects of treatments. Some of these rhythms have amplitudes as large as several 100%. Effects of many psychotropic medications depend on the time of administration in relation to body rhythmicity. Therefore, subtle circadian rhythm abnormalities related to developmental alcohol exposure may affect treatment response in patients with mood disorders.

Abstract
Many of the neurotoxic and neurobehavioral consequences of neonatal ethanol exposure in the rat have been characterized. However, in few studies has adult neurophysiologic function been assessed in rats exposed to ethanol during this key developmental period. In the current study, the effects of neonatal ethanol exposure on adult electroencephalographic (EEG) activity and auditory event-related potentials (ERPs) were examined in the rat. Male Sprague-Dawley rats were exposed to ethanol at 6.0 g/kg/day between postnatal days 4 through 9 by using an artificial-rearing procedure. Two control groups were used: a suckle control (SC) group and a gastrostomized control (GC) group. After reaching adulthood (i.e., at 3.5-4 months old), recording electrodes were implanted into the brain of each rat, so that EEG activity and auditory ERPs from the cortex and hippocampus could be assessed. Rats exposed to ethanol during the neonatal period were hyperactive as adults. Assessment of the EEG activity revealed that ethanol exposure increased peak frequency in the frontal cortical and parietal cortical 16-32 Hz frequency bands. Assessment of ERPs revealed that parietal cortical N1 amplitude was reduced in ethanol-exposed rats. Furthermore, parietal cortical N1 latency was increased in the GC group. These findings demonstrate that enhanced motor activity in rats exposed to ethanol during neonatal development occurs in combination with EEG indices of enhanced cortical and hippocampal arousal. Furthermore, a deficiency in cortical N1 amplitude indicates adult rats may have attention deficits. Overall, these results indicate that neonatal ethanol exposure has enduring neurobehavioral consequences, which persist into adulthood. This neurobehavioral profile in the rat is consistent with clinical observations of attention deficits and hyperactivity in children exposed to ethanol during prenatal development.

Abstract
Fetal alcohol syndrome (FAS) is a common cause of developmental disability, neuropsychiatric impairment and birth defects. The disorder is identified by the presence of growth impairment, central nervous system dysfunction, and a characteristic pattern of craniofacial features. The reported prevalence of the disorder varies widely and recent estimates approach 1% of live births. Expression of these features varies by age. People with FAS have high rates of comorbid conditions: attention deficit hyperactivity disorder (40%), mental retardation (15-20%), learning disorders (25%), speech and language disorders (30%), sensory impairment (30%), cerebral palsy (4%), epilepsy (8-10%). Birth defects are common. In the United States, the annual birth cohort of persons with FAS could be as high as 39,000 cases annually. Cause-specific mortality is 6% for patients with FAS. The disorder is expensive to treat and most patients have lifelong impairment. The annual cost of care in the United States would approach US$5.0 billion. Early recognition and entry into appropriate treatment programs appear to improve outcome. Prevention efforts should involve screening for alcohol use prior to pregnancy and at the first prenatal care visit.

Abstract
OBJECTIVE To test the sensitivity and specificity of fatty acid ethyl esters (FAEEs) extracted from meconium to identify alcohol-using pregnant women with a sensitive and specific methodology, gas chromatography-tandem mass spectroscopy (GC/MS/MS). Study design Twenty-seven samples of meconium were obtained from infants from the mixed race community in Cape Town, South Africa, who were enrolled in a longitudinal neurobehavioral study. Maternal alcohol use was reported prospectively during pregnancy. FAEEs were isolated from meconium and quantitated by GC/MS/MS. RESULTS Ethyl oleate was the FAEE that correlated most strongly with maternal self-reported drinking, especially with the average ounces of absolute alcohol ingested per drinking day. Ethyl oleate was most strongly related to drinking in the second and third trimesters (Pearson r=.55 and.40, respectively). At a threshold of 1.5 average ounces of absolute alcohol ingested per drinking day, the area under the receiving operator characteristic curve was.92 (95% confidence interval, 0.74-0.97). Using a cut-off value of 32 ng/g, sensitivity was 84.2% and specificity was 83.3%. CONCLUSIONS Ethyl oleate concentration in meconium assayed by GC/MS/MS provides a highly sensitive and specific indicator of maternal alcohol use during pregnancy.
