Abstract
PURPOSE The use of benzodiazepines and Z-hypnotics during pregnancy has raised significant concerns in recent years. However, there are limited data that capture the prescription patterns and predisposing factors in use of these drugs, particularly among women who have been long-term users of benzodiazepines and Z-hypnotics before pregnancy. METHODS This population-based cohort study comprised 2 930 988 pregnancies between 2004 and 2018 in Taiwan. Women who were dispensed benzodiazepines or Z-hypnotics during pregnancy were identified and further stratified into groups based on their status before pregnancy: long-term users (with a supply of more than 180 days within a year), short-term users (with a supply of less than 180 days within a year), and nonusers. Trends in the use of benzodiazepines or Z-hypnotics and concomitant use with antidepressants or opioids were assessed. Logistic regression models were utilized to identify factors associated with use of these drugs during pregnancy, and interrupted time series analyses (ITSA) were employed to evaluate utilization patterns of these drugs across different pregnancy-related periods. RESULTS The overall prevalence of benzodiazepine and Z-hypnotic use was 3.5% during pregnancy. Among prepregnancy long-term users, an upward trend was observed. The concomitant use of antidepressants or opioids among exposed women increased threefold (from 8.6% to 23.1%) and sixfold (from 0.3% to 1.7%) from 2004 to 2018, respectively. Women with unhealthy lifestyle behaviors, such as alcohol abuse (OR 2.48; 95% CI, 2.02-3.03), drug abuse (OR 10.34; 95% CI, 8.46-12.64), and tobacco use (OR 2.19; 95% CI, 1.96-2.45), as well as those with psychiatric disorders like anxiety (OR 6.99; 95% CI, 6.77-7.22), insomnia (OR 15.99; 95% CI, 15.55-16.45), depression (OR 9.43; 95% CI, 9.07-9.80), and schizophrenia (OR 21.08; 95% CI, 18.76-23.69), and higher healthcare utilization, were more likely to use benzodiazepines or Z-hypnotics during pregnancy. ITSA revealed a sudden decrease in use of benzodiazepines and Z-hypnotics after recognition of pregnancy (level change -0.55 percentage point; 95% CI, -0.59 to -0.51). In contrast, exposures to benzodiazepines and Z-hypnotics increased significantly after delivery (level change 0.12 percentage point; 95% CI, 0.09 to 0.16). CONCLUSIONS In this cohort study, an increased trend of benzodiazepine and Z-hypnotic use during pregnancy among prepregnancy long-term users, as well as concomitant use with antidepressants or opioids were found. The findings have highlighted the existence of various risk factors associated with the use of these drugs during pregnancy. Utilization patterns varied across different stages of pregnancy, highlighting the need for prescription guidelines and educational services for women using these drugs during pregnancy.

Abstract
Importance Benzodiazepine use during pregnancy has raised significant concerns due to the potential harmful effects of this drug class on neonates. Studies on the association between benzodiazepine use and the risk of miscarriage are limited. Objective To quantify the risk of miscarriage associated with benzodiazepine use during pregnancy after controlling for unmeasured confounders and exposure time trends. Design, Setting, and Participants This was a nationwide, population-based case-time-control study using Taiwan's National Birth Certificate Application database and the National Health Insurance database. Pregnancies resulting in miscarriage between 2004 and 2018 were included in the case group and were 1:1 matched with exposure time-trend control individuals using disease risk score, considering demographic characteristics and prepregnancy comorbidities. Data were analyzed from August 2022 to March 2023. Exposures Discordant exposures to benzodiazepines during risk period (1-28 days before miscarriage) and 2 reference periods (31-58 days and 181-208 days before the last menstrual period) were compared for each pregnancy. Main Outcomes and Measures Miscarriage was defined as any pregnancy loss occurring between the first prenatal care visit (usually 8 weeks) and the 19th completed week of pregnancy. Results This study comprised a total of 3 067 122 pregnancies among 1 957 601 women, 136 134 of which (4.4%) resulted in miscarriage. The mean (SD) age of the study population was 30.61 (5.91) years. The use of benzodiazepines during pregnancy was associated with an increased risk of miscarriage (odds ratio [OR], 1.69; 95% CI, 1.52-1.87), and consistent findings were observed across multiple sensitivity analyses considering different time windows and accounting for misclassification. In subgroup analyses, an increased risk of miscarriage was associated with each commonly used individual benzodiazepine, ranging from case-time-control ORs of 1.39 (95% CI, 1.17-1.66) for alprazolam to 2.52 (95% CI, 1.89-3.36) for fludiazepam. Conclusions and Relevance This nationwide case-time-control study revealed an increased risk of miscarriage associated with benzodiazepine use during pregnancy after accounting for measurable confounders, and results were unlikely to be due to unmeasured confounding. These findings underscore the necessity for health care professionals to meticulously balance the risk-benefit ratio when considering the use of benzodiazepines to treat psychiatric and sleep disorders during pregnancy.

Association between maternal benzodiazepine or Z-hypnotic use in early pregnancy and the risk of stillbirth, preterm birth, and small for gestational age: a nationwide, population-based cohort study in Taiwan. Lancet Psychiatry 2023; 10:499-508. [PMID: 37353262 DOI: 10.1016/s2215-0366(23)00148-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/16/2023] [Accepted: 04/17/2023] [Indexed: 06/25/2023]
Abstract
BACKGROUND Benzodiazepines and Z-hypnotics are commonly prescribed for anxiety and insomnia during pregnancy, but the evidence regarding potential adverse neonatal outcomes is insufficient because of poor control for confounding factors in previous studies. We therefore aimed to evaluate the association between the use of benzodiazepines or Z-hypnotics during early pregnancy and adverse neonatal outcomes (stillbirth, preterm birth, and small for gestational age). METHODS We did a nationwide, population-based cohort study in Taiwan using three data sources: Taiwan's National Birth Certificate Application database, the National Health Insurance database, and the Maternal and Child Health Database. The study cohort included all singleton pregnancies of females aged 15-50 years who gave birth between Jan 1, 2004, and Dec 31, 2018. Pregnancies without valid information were excluded. Benzodiazepine and Z-hypnotic use was defined as at least one benzodiazepine or Z-hypnotic prescription during early pregnancy (the first 20 weeks of pregnancy). The primary outcomes were stillbirth (fetal death at or after 20 weeks' gestation), preterm birth (<37 weeks' gestation), and small for gestational age (birthweight below the 10th percentile for gestational age by sex). Logistic regression models with propensity score fine stratification weighting were used to control for potential confounders and examine the association between benzodiazepines or Z-hypnotics use during early pregnancy and the risk of adverse neonatal outcomes. Odds ratios (ORs) and 95% CIs were reported. We used confounding by indication control analyses, a sibling control study, and a paternal negative control design to account for unmeasured confounders. The risk associated with exposure during late pregnancy was also assessed. FINDINGS Between Oct 7, 2021, and June 10, 2022, we analysed the study data. The cohort included 2 882 292 singleton pregnancies; of which, 75 655 (2·6%) of the mothers were dispensed one or more benzodiazepines or Z-hypnotics during early pregnancy. Women exposed during pregnancy were older (mean age at delivery was 31·0 years [SD 5·3] for exposed women vs 30·6 years [4·9] for unexposed women), had a higher prevalence of psychiatric disorders, and were more likely to have unhealthy lifestyle behaviours than unexposed women. Information about ethnicity was not available. Early pregnancy exposure was associated with adverse neonatal outcomes compared with non-exposure. The propensity score-weighted OR was 1·19 (95% CI 1·10-1·28) for stillbirth, 1·19 (1·16-1·23) for preterm birth, and 1·16 (1·13-1·19) for small for gestational age. After controlling for confounding by indication, there was no significant association between drug exposure and stillbirth risk; however, this attenuation was not observed for preterm birth and small for gestational age. In models with sibling controls that accounted for familial confounding and genetic factors, early exposure to benzodiazepines or Z-hypnotics was not associated with an increased risk of stillbirth and preterm birth, but it remained significantly associated with small for gestational age. The paternal negative control analyses with point estimates close to the null indicated no strong evidence of unmeasured confounding shared by the mother and the father. Substantially increased risks of stillbirth and preterm birth were observed for late pregnancy exposure. INTERPRETATION Benzodiazepine or Z-hypnotic use in early pregnancy is not associated with a substantial increase in the risk of stillbirth and preterm birth after accounting for unmeasured confounding factors. Clinicians should be aware of the increased risk of small for gestational age and caution should be taken when prescribing these medications during late pregnancy.

Immunological evaluation of herbal extracts commonly used for treatment of mental diseases during pregnancy. Sci Rep 2023; 13:9630. [PMID: 37316493 DOI: 10.1038/s41598-023-35952-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 05/26/2023] [Indexed: 06/16/2023] Open
Abstract
Nonpsychotic mental diseases (NMDs) affect approximately 15% of pregnant women in the US. Herbal preparations are perceived a safe alternative to placenta-crossing antidepressants or benzodiazepines in the treatment of nonpsychotic mental diseases. But are these drugs really safe for mother and foetus? This question is of great relevance to physicians and patients. Therefore, this study investigates the influence of St. John's wort, valerian, hops, lavender, and California poppy and their compounds hyperforin and hypericin, protopine, valerenic acid, and valtrate, as well as linalool, on immune modulating effects in vitro. For this purpose a variety of methods was applied to assess the effects on viability and function of human primary lymphocytes. Viability was assessed via spectrometric assessment, flow cytometric detection of cell death markers and comet assay for possible genotoxicity. Functional assessment was conducted via flow cytometric assessment of proliferation, cell cycle and immunophenotyping. For California poppy, lavender, hops, and the compounds protopine and linalool, and valerenic acid, no effect was found on the viability, proliferation, and function of primary human lymphocytes. However, St. John's wort and valerian inhibited the proliferation of primary human lymphocytes. Hyperforin, hypericin, and valtrate inhibited viability, induced apoptosis, and inhibited cell division. Calculated maximum concentration of compounds in the body fluid, as well as calculated concentrations based on pharmacokinetic data from the literature, were low and supported that the observed effects in vitro would probably have no relevance on patients. In-silico analyses comparing the structure of studied substances with the structure of relevant control substances and known immunosuppressants revealed structural similarities of hyperforin and valerenic acid to the glucocorticoids. Valtrate showed structural similarities to the T cells signaling modulating drugs.

The role of prenatal exposure to antidepressants, anxiolytic, and hypnotics and its underlying illness on the risk of miscarriage using BIFAP database. Pharmacoepidemiol Drug Saf 2022; 31:901-912. [PMID: 35689300 PMCID: PMC9543237 DOI: 10.1002/pds.5488] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 03/21/2022] [Accepted: 06/05/2022] [Indexed: 12/04/2022]
Abstract
Purpose Despite the notable increase on the prescription of antidepressants and anxiolytics during pregnancy, recommendation on maintaining the treatment during prenatal period is still controversial. We aimed to separately assess the role of effects of the antidepressants and anxiolytic and the underlying illness, controlled by potential confounding associated with miscarriage onset. Methods We used data from a validated pregnant cohort aged 15–49 years from 2002 to 2016 using BIFAP database. All confirmed miscarriages were used to perform a nested control analysis using conditional logistic regression. Women were classified according to use of each drug of interest into four mutually exclusive groups: nonusers, users only during prepregnancy, continuers, and initiators during first trimester. Adjusted odds ratios (aORs) for major confounders during pregnancy such as number of visits to primary care practitioners visits, obesity, smoking, HTA, diabetes with 95% confidence intervals were calculated. Results Compared with nonusers, antidepressants continuers had the highest increased risk of miscarriage aOR (95%) of 1.29 (1.13–1.46), being continuers of paroxetine and fluoxetine the antidepressants with the strongest association. Likewise, continuers of anxiolytics and initiators showed an increased risk of 1.19 (1.04–1.37) and 1.30 (1.13–1.50). When separating the effect between the condition itself or the treatment, women exposed during first trimester, regardless treatment duration and/or the underlying illness, had the highest risk 1.27 (1.08–1.51) for antidepressants and 1.25 (1.13–1.39) for anxiolytics. Conclusions Our analysis showed an association between prenatal exposure to antidepressants and anxiolytics and miscarriage onset after controlling by potential confounding adjusting for confounders and the underlying illness. This association was not supported for hypnotic medications. Further studies are warranted to evaluate the risk of miscarriage among subpopulation of pregnant women requiring these medications.

Abstract
Insomnia symptoms are frequent during peripartum and are considered risk factors for peripartum psychopathology. Assessing and treating insomnia and related conditions of sleep loss during peripartum should be a priority in the clinical practice. The aim of this paper was to conduct a systematic review on insomnia evaluation and treatment during peripartum which may be useful for clinicians. The literature review was carried out between January 2000 and May 2021 on the evaluation and treatment of insomnia during the peripartum period. The PubMed, PsycINFO, and Embase electronic databases were searched for literature published according to the PRISMA guidance with several combinations of search terms "insomnia" and "perinatal period" or "pregnancy" or "post partum" or "lactation" or "breastfeeding" and "evaluation" and "treatment." Based on this search, 136 articles about insomnia evaluation and 335 articles on insomnia treatment were found and we conducted at the end a narrative review. According to the inclusion/exclusion criteria, 41 articles were selected for the evaluation part and 22 on the treatment part, including the most recent meta-analyses and systematic reviews. Evaluation of insomnia during peripartum, as for insomnia patients, may be conducted at least throughout a clinical interview, but specific rating scales are available and may be useful for assessment. Cognitive behavioral therapy for insomnia (CBT-I), as for insomnia patients, should be the preferred treatment choice during peripartum, and it may be useful to also improve mood, anxiety symptoms, and fatigue. Pharmacological treatment may be considered when women who present with severe forms of insomnia symptoms do not respond to nonpharmacologic therapy.

Abstract
INTRODUCTION Status epilepticus (SE) in pregnancy represents a life-threatening medical emergency for both mother and fetus. Pregnancy-related pharmacokinetic modifications and the risks for fetus associated with the use of antiseizure medications (ASMs) and anesthetic drugs complicate SE management. No standardized treatment protocol for SE in pregnancy is available to date. AREAS COVERED In this review, we provide an overview of the current literature on the management of SE in pregnancy and we propose a multidisciplinary-based protocol approach. EXPERT OPINION Literature data are scarce (mainly anecdotal case reports or small case series). Prompt treatment of SE during pregnancy is paramount and a multidisciplinary team is needed. Benzodiazepines are the drugs of choice for SE in pregnancy. Levetiracetam and phenytoin represent the most suitable second-line agents. Valproic acid should be administered only if other ASMs failed and preferably avoided in the first trimester of pregnancy. For refractory SE, anesthetic drugs are needed, with propofol and midazolam as preferred drugs. Magnesium sulfate is the first-line treatment for SE in eclampsia. Termination of pregnancy, via delivery or abortion, is recommended in case of failure of general anesthetics. Further studies are needed to identify the safest and most effective treatment protocol.

Abstract
BACKGROUND Benzodiazepines are frequently prescribed during pregnancy; however, evidence about possible teratogenicity is equivocal. We aimed to evaluate the association between first-trimester benzodiazepine use and the risk of major congenital malformations. METHODS AND FINDINGS Using Korea's nationwide healthcare database, we conducted a population-based cohort study of women who gave birth during 2011 to 2018 and their live-born infants. The exposure was defined as one or more benzodiazepine prescriptions during the first trimester. We determined the relative risks (RRs) and confidence intervals (CIs) of overall congenital malformations and 12 types of organ-specific malformations. Infants were followed from birth to death or 31 December 2019, whichever came first (up to 8 years of age). Propensity score fine stratification was employed to control for 45 potential confounders. Among a total of 3,094,227 pregnancies, 40,846 (1.3%) were exposed to benzodiazepines during the first trimester (mean [SD] age, 32.4 [4.1] years). The absolute risk of overall malformations was 65.3 per 1,000 pregnancies exposed to benzodiazepines versus 51.4 per 1,000 unexposed pregnancies. The adjusted RR was 1.09 (95% CI 1.05 to 1.13, p < 0.001) for overall malformations and 1.15 (1.10 to 1.21, p < 0.001) for heart defects. Based on mean daily lorazepam-equivalent doses, the adjusted RRs for overall malformations and heart defects were 1.05 (0.99 to 1.12, p = 0.077) and 1.12 (1.04 to 1.21, p = 0.004) for <1 mg/day and 1.26 (1.17 to 1.36, p < 0.001) and 1.31 (1.19 to 1.45, p < 0.001) for >2.5 mg/day doses, respectively, suggesting a dose-response relationship. A small but significant increase in risk for overall and heart defects was detected with several specific agents (range of adjusted RRs: 1.08 to 2.43). The findings were robust across all sensitivity analyses, and negative control analyses revealed a null association. Study limitations include possible exposure misclassification, residual confounding, and restriction to live births. CONCLUSIONS In this large nationwide cohort study, we found that first-trimester benzodiazepine exposure was associated with a small increased risk of overall malformations and heart defects, particularly at the higher daily dose. The absolute risks and population attributable fractions were modest. The benefits of benzodiazepines for their major indications must be considered despite the potential risks; if their use is necessary, the lowest effective dosage should be prescribed to minimize the risk.

Abstract
Our aim was to evaluate maternal use of sedative drugs before, during, and after pregnancy and to assess the influence of use of these drugs on pregnancy outcomes. The study cohort (N = 6231) consists of all primiparous women, who lived in the city of Vantaa, Finland, and who delivered a singleton between 2009 and 2015. Data were obtained from Finnish national health registers. Of the women, 3.2% (n = 202) purchased at least once sedative drugs within 90 days before conception, during pregnancy and/or within 90 days after delivery. Sedative drug users were older, less likely to cohabitate, more often smokers, had lower educational attainment and had more mental diseases (for all p < 0.001) compared with non-users. Sedative drug users purchased more often antidepressants and drugs for the alimentary tract, musculoskeletal and nervous system than non-users (for all p < 0.001). No adverse birth or pregnancy outcomes were found in the group using sedative drugs compared with the non-users. Studies in larger cohorts are needed to confirm our study findings.

[PMID: 32064503 DOI: 10.1093/jat/bkaa012] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2019] [Revised: 04/03/2019] [Accepted: 11/29/2019] [Indexed: 12/17/2022] Open
Abstract
An LC-MS-MS method for the determination of 14 benzodiazepines (BZDs) (alprazolam, α-hydroxyalprazolam, clonazepam, bromazepam, diazepam, nordiazepam, lorazepam, lormetazepam, oxazepam, flunitrazepam, 7-aminoflunitrazepam, triazolam, midazolam and zolpidem) and 15 antidepressants (ADs) (amitriptyline, nortriptyline, imipramine, desipramine, clomipramine, norclomipramine, fluoxetine, norfluoxetine, sertraline, norsertraline, paroxetine, venlafaxine, desmethylvenlafaxine, citalopram and desmethylcitalopram) in meconium was developed and validated. Meconium samples (0.25 ± 0.02 g) were homogenized in methanol and subjected to mixed-mode cation exchange solid-phase extraction. Chromatographic separation was performed in reversed phase, with a gradient of 0.1% formic acid in 2 mM ammonium formate and acetonitrile. Two different chromatographic gradient methods were employed, one for the separation of ADs and another for BZDs. Analytes were monitored by tandem mass spectrometry employing electrospray positive mode in MRM mode (2 transitions per compound). Method validation included: linearity [n = 5, limit of quantification (LOQ) to 400 ng/g], limits of detection (n = 6, 1-20 ng/g), LOQ (n = 9, 5-20 ng/g), selectivity (no endogenous or exogenous interferences), accuracy (n = 15, 90.6-111.5%), imprecision (n = 15, 0-14.6%), matrix effect (n = 10, -73 to 194.9%), extraction efficiency (n = 6, 35.9-91.2%), process efficiency (n = 6, 20.1-188.2%), stability 72 h in the autosampler (n = 3, -8.5 to 9%) and freeze/thaw stability (n = 3, -1.2 to -47%). The method was applied to four meconium specimens, which were analyzed with and without hydrolysis (enzymatic and alkaline). The authentic meconium samples tested positive for alprazolam, α-hydroxyalprazolam, clonazepam, diazepam, nordiazepam, fluoxetine, norfluoxetine, clomipramine and norclomipramine. Therefore, the present LC-MS-MS method allows a high throughput determination of the most common BZDs and ADs in meconium, which could be useful in clinical and forensic settings.

Abstract
Drugs can have harmful effects on the embryo or the fetus at any point during pregnancy. Not all the damaging effects of intrauterine exposure to drugs are obvious at birth, some may only manifest later in life. Thus, drugs should be prescribed in pregnancy only if the expected benefit to the mother is thought to be greater than the risk to the fetus. Dosing of drugs during pregnancy is often empirically determined and based upon evidence from studies of non-pregnant subjects, which may lead to suboptimal dosing, particularly during the third trimester. This review collates examples of drugs with known recommendations for dose adjustment during pregnancy, in addition to providing an example of the potential use of PBPK models in dose adjustment recommendation during pregnancy within the context of drug-drug interactions. For many drugs, such as antidepressants and antiretroviral drugs, dose adjustment has been recommended based on pharmacokinetic studies demonstrating a reduction in drug concentrations. However, there is relatively limited (and sometimes inconsistent) information regarding the clinical impact of these pharmacokinetic changes during pregnancy and the effect of subsequent dose adjustments. Examples of using pregnancy PBPK models to predict feto-maternal drug exposures and their applications to facilitate and guide dose assessment throughout gestation are discussed.

Prevalence of benzodiazepines and benzodiazepine-related drugs exposure before, during and after pregnancy: A systematic review and meta-analysis. J Affect Disord 2020; 269:18-27.

Abstract
BACKGROUND Maternal use of benzodiazepines during pregnancy is common and has increased over the last decades. In this systematic review and meta-analysis, we studied the literature to estimate the worldwide use of benzodiazepines before, during and after pregnancy, which could help to estimate benzodiazepine exposure and to prioritize and guide future investigations. METHODS We systematically searched Embase, Medline Ovid, Web of Science and Cochrane Central up until July 2019 for studies reporting on benzodiazepine use before (12 months), during and after pregnancy (12 months). Random effects meta-analysis was conducted to calculate pooled prevalence estimates, as well as stratified according to substantive variables. RESULTS We identified 32 studies reporting on 28 countries, together reporting on 7,343,571 pregnancies. The worldwide prevalence of benzodiazepine use/prescriptions during pregnancy was 1.9% (95%CI 1.6%-2.2%; I2 97.48%). Highest prevalence was found in the third trimester (3.1%; 95%CI 1.8%-4.5%; I2 99.83%). Lorazepam was the most frequently used/prescribed benzodiazepine (1.5%; 95%CI 0.5%-2.5%; I2 99.87%). Highest prevalence was found in Eastern Europe (14.0%; 95%CI 12.1%-15.9%; I2 0.00%). LIMITATIONS All analyses revealed considerable heterogeneity. CONCLUSIONS Our meta-analysis confirmed that benzodiazepine use before, during and after pregnancy is prevalent. The relatively common use of benzodiazepines with possible risks for both mother and (unborn) child is worrying and calls for prescription guidelines for women, starting in the preconception period. Given the substantial proportion of children exposed to benzodiazepines in utero, future research should continue to study the short- and long-term safety of maternal benzodiazepine use during pregnancy and to explore non-pharmacological alternative treatments.

Abstract
Brain disorders and mental diseases, in particular, are common and considered as a top global health challenge for the twenty-first century. Interestingly, women suffer more frequently from mental disorders than men. Moreover, women may respond to psychotropic drugs differently than men, and, through their lifespan, they endure sex-orientated social stressors. In this chapter, we present how women may differ in the development and manifestation of mental health issues and how they differ from men in pharmacokinetics and pharmacodynamics. We discuss issues in clinical trials regarding women participation, issues in the use of psychotropic medications in pregnancy, and challenges that psychiatry faces as a result of the wider use of contraceptives, of childbearing at older age, and of menopause. Such issues, among others, demand further women-oriented psychiatric research that can improve the care for women during the course of their lives. Indeed, despite all these known sex differences, psychiatry for both men and women patients uses the same approach. Thereby, a modified paradigm for women's psychiatry, which takes into account all these differences, emerges as a necessity, and psychiatric research should take more vigorously into account sex differences.

Abstract
BACKGROUND Breastfeeding women who are prescribed with psychotropic medications on a regular basis are often concerned, regarding the possible implications of such treatment on the breastfed infant. A mother's well-being has a direct influence on the well-being of the baby. However, the notorious reputation of psychotropic medications may lead to suboptimal prescribing by the physician and poor adherence by the mother. METHODS A PubMed search (from 1976 through February 2017) was conducted for commonly used psychotropic drug classes, as well as individual medications commonly prescribed in these classes, along with the MeSH terms "breastfeeding"/"lactation". In each case, we chose studies that describe the pharmacokinetics of passage into breast milk and/or adverse effects in breastfed infants. RESULTS No large-scale controlled studies regarding the safety of psychotropic medications in breastfeeding mothers were reported. Based on case reports and small studies, most psychotropic medications produce low milk levels and low plasma levels in the infant, while serious adverse effects in the breastfed infant are rarely reported. Safety data for some psychotropic medications are still unavailable. CONCLUSION According to the data available in the literature to date, most psychotropic medications are expected to produce low levels in breast milk with no clinical importance. Nevertheless, an individual risk-benefit assessment of a proposed treatment should always be performed, as inter-individual differences may have a substantial effect on the breastfeeding infant's response to the treatment. Further studies and additional objective data are needed to consolidate and improve our current knowledge of psychopharmacotherapy in breastfeeding women.

Abstract
Benzodiazepines and benzodiazepine-related medications (BBRMs) are anxiolytics and hypnotics acting on γ-amino butyric acid (GABA)A receptors. BBRMs are assumed to have a low potential for major congenital malformations, but research on more subtle and protracted developing symptoms of these medications is lacking. Therefore, we prospectively investigated the association between BBRM use in pregnancy and long-term effects on child behavior in a large population-based cohort study. The study population consisted of 104 children prenatally exposed to BBRM, 527 children exposed to maternal prenatal anxiety or phobic anxiety symptoms (without exposure to BBRM), and 5609 control children. At child age, 6years, Oppositional Defiant Disorder (ODD), Aggressive Behavior and Anxiety Problems were assessed by the Child Behavior Checklist (CBCL) reported by the mother and the Teacher Report Form (TRF). Children prenatally exposed to BBRM had higher scores of ODD and aggressive behavior, but not of anxiety. However, these associations were explained by maternal anxiety symptoms during pregnancy. Moreover, prenatal exposure to anxiety (without exposure to BBRM) was associated with increased scores of child ODD, aggressive behavior, and anxiety. In conclusion, the current study demonstrates that prenatal BBRM exposure was not independently associated with ODD and aggressive behavior in childhood when prenatal anxiety symptoms were taken into account.

Abstract
Objective:To provide a guide for practicing pharmacists, pharmacy technicians, and other healthcare professionals so that they are able to counsel and advise breast-feeding mothers and fellow healthcare professionals on the safety and use of antiinfectives, vaccines, antiepileptics, benzodiazepines, psychotherapeutic drugs, and radiopharmaceuticals during breast-feeding.Data Sources:Primary texts used by the breast-feeding community ( Medications and Mothers' Milk, Drugs in Pregnancy and Lactation, Drugs and Human Lactation) were searched, as well as Micromedex, MEDLINE, PubMed, EMBASE, and EMBASE2 (1984–February 2004).Study Selection/Data Extraction:Multiple sources were used wherever available to validate the data, and primary articles were used to verify all tertiary source information. Search terms included breast-feeding, lactation, nursing, and medications, as well as specific drug names.Data Synthesis:Concerns regarding medication use during breast-feeding have caused mothers to either discontinue nursing or not take necessary medications. Complete avoidance of medications or cessation of breast-feeding is often unnecessary. Although there are drugs that can be harmful to nursing infants, breast-milk concentrations of most drugs are insufficient to cause any harm.Conclusions:Having objective and reliable information on medications enables pharmacists, pharmacy technicians, other healthcare providers, and mothers to make educated decisions regarding drug therapy and breast-feeding.

Abstract
BACKGROUND AND PURPOSE The quality of spectroscopic studies may be limited because of unrestricted fetal movement. Sedation is recommended to avoid motion artefacts. However, sedation involves side effects. The aim of this study was to assess the feasibility and quality of brain (1)H-MR spectroscopy in unsedated fetuses and to evaluate whether quality is dependent on the type of spectra, fetal presentation, GA, and/or fetal pathology. MATERIALS AND METHODS Seventy-five single-voxel spectroscopic studies of the fetal brain, performed at gestational weeks 19-38 at 1.5T, were evaluated retrospectively. A PRESS (TE = 144 or 35 ms) was used. Fetal presentation, GA, and kind of pathology were recorded. The quality of the spectra was assessed by reviewing the spectral appearance (line width, signal-to-noise) of the creatine resonance obtained relative to concentrations (ratios-to-creatine) of choline, myo-inositol, and NAA. RESULTS Of 75 studies, 50 (66.6%) were rated as readable: short TE = 17/50 (34%), long TE = 33/50 (66%), cephalic presentation in 36/50 (72%) studies, breech in 10/50 (20%) studies, and "other" presentation in 4/50 (8%) studies (mean GA, 31.0 weeks). Twenty-eight of 50 fetuses (56%) showed normal development (short TE = 12/28, long TE = 16/28), and 22/50 (44%) showed pathology. Of the 75 studies, 25 (33.3%) were not readable: short TE = 14/25 (56%), long TE = 11/25 (44%), cephalic presentation in 20/25 (80%) studies, breech in 4/25 (16%) studies, and other presentation in 1 study (4%) (mean GA, 30.1 week). Thirteen of 25 fetuses (52%) showed normal development; 12/25 (48%) showed pathology. Statistical analysis revealed no impact of the different parameters on the quality of spectra. CONCLUSIONS Single-voxel spectroscopy can be performed in approximately two-thirds of unsedated fetuses, regardless of the type of spectra, fetal presentation, GA, and pathology.

Abstract
OBJECTIVE To study the possible human teratogenicity of short-term (generally 3 weeks) oral diazepam treatment during pregnancy. DESIGN AND SETTING A matched case-population control pair analysis based on the total (maternal self-reported and medically recorded) or medically recorded diazepam treatments, in addition to a comparison between cases and patient controls in the population-based large data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities from 1980 to 1996. STUDY PARTICIPANTS 38 151 population-control neonates without any congenital abnormalities, 22 865 neonates or fetuses with congenital abnormalities (cases) and 812 neonates or fetuses with Down's syndrome (patient controls). MAIN OUTCOME MEASURES 24 congenital abnormality groups. RESULTS 2746 (12.0%) cases, 4130 (10.8%) population controls and 97 (11.9%) patient controls were born to mothers treated with diazepam during pregnancy. The matched case-population control pair analysis showed a higher rate of limb deficiencies, rectal-anal atresia/stenosis, cardiovascular malformations and multiple congenital abnormalities after diazepam use during the second and third months of gestation, i.e. in the critical period for most major congenital abnormalities, based on maternal self-reported and medically recorded information. However, the evaluation of only medically recorded diazepam use did not indicate a higher use of diazepam in any congenital abnormality group. Thus, the higher occurrence of diazepam treatment among cases in the primary analysis may be due to the lower proportion of maternal self-reported diazepam intake in the population control group, i.e. recall bias. The comparison of diazepam use between 24 congenital abnormality groups and patient controls as the referent group showed a difference only in the group of intestinal atresia/stenosis, probably due to chance error caused by multiple comparison. CONCLUSIONS Short-term diazepam treatment in usual therapeutic doses during pregnancy did not present any detectable teratogenic risk to the fetus.

Abstract
BACKGROUND Excessive alcohol use during pregnancy has been associated with adverse maternal and neonatal effects. It is therefore important to develop and evaluate effective interventions during this important time in a woman's life. To our knowledge there have been no systematic reviews of randomised control trials (RCT) in this population. OBJECTIVES To evaluate the effectiveness of pharmacologic interventions in pregnant women enrolled in alcohol treatment programs for improving birth and neonatal outcomes, maternal abstinence and treatment retention. SEARCH STRATEGY We searched the Cochrane Drugs and Alcohol Group's Trial register (August 2008) ; MEDLINE (1.1950 to 6.2008) ; EMBASE (1.1974 - 8.2008); CINAHL (1.1982-6.2008); PsycInfo (1.1806-6.2008), and reference lists of articles. SELECTION CRITERIA We sought to include randomised or quasi-randomised studies comparing any pharmacologic intervention versus other pharmacologic treatment alone or in association with psychosocial treatment, placebo, non-intervention or psychosocial intervention. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion in the review. Included studies were to be assessed using standardized data extraction and quality assessment forms. No suitable trials were identified. MAIN RESULTS The search strategy identified 793 citations. Twenty-three citations were deemed relevant for full text review; an additional ten articles were retrieved through hand searching references, for a total of thirty-three articles. Following full text review no articles met the inclusion criteria. Data extraction and assessment of methodological quality were therefore not possible. AUTHORS' CONCLUSIONS The review question remains unanswered as there were no randomised control trials found relevant to the topic. There is a need for high quality research to determine the effectiveness of pharmacologic interventions in pregnant women enrolled in alcohol treatment program.

Abstract
The teratogenic potential of diazepam is debated. The objective of this study was to examine the effects of extremely high doses of diazepam used for attempted suicide during pregnancy on embryo-fetal development. Pregnant women were identified from the female patients of the Department of Toxicology Internal Medicine, Korányi Hospital, Budapest, who had been admitted as self-poisoned subjects from the three million people of Budapest and the surrounding region. This evaluation compares the incidences and types of congenital abnormalities observed in exposed children born to mothers who attempted suicide with diazepam alone or in combination with other drugs during pregnancy with their sib controls. The database consists of a total of 1044 women with self-poisoning during pregnancy between 1960 and 1993. Of these 1044 self-poisoned pregnant women, 229 (21.9%) used diazepam with or without other drugs for a suicide attempt; 112 of these women delivered live-born infants. Doses of diazepam taken ranged between 25 and 800 mg. Of 112 exposed children, 15 (13.4%) had congenital abnormalities, whereas of their 112 matched sibs, eight (7.1%) had congenital abnormalities (odds ratios with 95% confidence intervals: 2.0, 0.8-5.0). Of 37 pregnant women who attempted suicide between the 4th and 12th postconceptional weeks, five (13.5%) delivered live-born babies with a congenital abnormality (undescended testis in two exposed children; congenital dysplasia of the hip, talipes equinovarus deformation type, congenital inguinal hernia-each in one exposed child). The suicide attempts of the mothers of these children did not occur during the critical periods for induction of these defects, indicating that the observations were unrelated to diazepam. The very large doses of diazepam used for self-poisoning during pregnancy did not increase the rate of congenital abnormalities in the offspring.

Abstract
The purpose of this article is to report an evaluation of the teratogenic and fetotoxic potential of medezepam in humans based on pregnant women who used very large doses of medazepam for a suicide attempt. All self-poisoned patients were cared for at the Department of Toxicology Internal Medicine, Koranyi Hospital, a toxicological inpatients clinic in Budapest, Hungary, between 1960 and 1993. Pregnant women were identified from self-poisoned subjects admitted from a population base of three million people of Budapest and the surrounding region. The rates of congenital abnormalities (CAs), intrauterine fetal development, cognitive and behavioral status in children born to mothers who attempted suicide with medazepam alone or in combination with other drugs during pregnancy was compared in their sib controls. Between 1980 and 1993, 835 pregnant women in our study attempted suicide during pregnancy with drugs. Of these, 314 delivered live-born infants and 283 were examined and/or evaluated. Thirty-two (3.8%) of these 835 pregnant women used medazepam with or without other drugs for self-poisoning; 10 of these women delivered live-born babies. The dose of medazepam used for the suicide attempt ranged between 60 and 500 mg, with a mean of 276 mg. Eight of the 32 suicide attempts involving medazepam occurred between the 4th and 12th postconceptional weeks. Of the 10 live-born exposed children, one was affected with congenital inguinal hernia; one of the 13 sib controls had a lethal hydronephrosis. No adverse effects were observed on intrauterine growth, cognitive status, or behavioral deviations in the 10 children born to mothers who attempted suicide with medazepam during pregnancy. Very large doses of medazepam were used for self-poisoning during pregnancy. These doses did not increase the rate of CAs even though eight mothers attempted suicide during the most critical period for production of CAs. No fetotoxic, including neurotoxic, effects of exposure of live-born children to a very large dose of medazepam were observed. Our experiences show the feasibility and benefits of use of the self-poisoning model in estimating human teratogenic and fetotoxic risks of drugs.

Abstract
FDA has identified alprazolam, a new type of benzodiazepine, as pregnancy category D. The objective of this study was to evaluate the effects on fetal development of very large doses of alprazolam that were used for suicide attempts during pregnancy. Pregnant women were identified among the patients of the Department of Toxicology Internal Medicine, Korányi Hospital, Budapest, who were admitted as self-poisoned subjects from a total population of the three million people of Budapest and its surrounding region. Rates of congenital abnormalities, intrauterine fetal development, and cognitive-behavioral status were compared between children born to mothers who attempted suicide during pregnancy using alprazolam alone or in combination with other drugs and in their sib controls. Between 1984 and 1993, 559 pregnant women attempted suicide during pregnancy with drugs: 30 of these women self-poisoned with alprazolam, 10 delivered live-born infants who were examined. Doses of alprazolam used were between 7.5 and 100 mg, with a mean of 30 mg. Six of the 10 exposed children were born to mothers who attempted suicide between the 6th and 12th postconceptional weeks. Of the 10 exposed children, two had congenital abnormalities. One had a multiple congenital abnormality that included atypical gastroschisis and minor anomalies; an association of this defect and the 30 mg alprazolam used for self-poisoning in the 14th postconceptional week cannot be excluded. Another exposed child had mild pectus excavatum, but the times of the suicide attempt and the critical period for producing this defect did not overlap. Of 12 sibs, one had a multiple congenital abnormality. Thus, the rate of congenital abnormalities did not significantly differ between exposed children and their sibs. Mean birth weight was higher for babies born to mothers who attempted suicide by alprazolam during pregnancy than in their sib controls. Cognitive status and behavioral scale of the exposed children did not indicate fetotoxic effects, including neurotoxic effects, of large doses of alprazolam. The large doses of alprazolam used for self-poisoning during pregnancy did not result in a significantly higher rate of congenital abnormalities; however, there were only 10 self-poisoned pregnant women, and an association of one multiple congenital abnormality with a large dose of alprazolam cannot be excluded. The findings in this study did not identify fetotoxicity, including neurotoxicity, of very large doses of alprazolam. Our study shows that the self-poisoning model is feasible and provides beneficial information for use in estimating human teratogenic and fetotoxic risks of drugs.

Abstract
The human teratogenic potential of chlordiazepoxide is debated. To study the effects on the fetal development of very large doses of chlordiazepoxide that were used for a suicide attempt during pregnancy, self-poisoned pregnant women were identified from patients in a toxicological inpatient clinic in Budapest, Hungary. Comparisons were made between congenital abnormalities, intrauterine fetal development, and cognitive–behavioral status of the exposed children born to mothers who attempted suicide with chlordiazepoxide alone or in combination with other drugs during pregnancy and their sib controls. Of 1044 women with self-poisoning during pregnancy between 1960 and 1993, 88 (8.4%) used chlordiazepoxide with or without other drugs for suicide attempt; 35 of these women delivered live-born infants. Doses of chlordiazepoxide taken ranged between 20 and 300 mg, with a mean of 117 ± 86 mg. Of 35 exposed children, six (17.1 %) were affected with congenital abnormalities compared with three (13.6%) of their 22 sibs (OR with 95% CI: 1.3 (0.3–4.4). Of 18 pregnant women who attempted suicide between the 4th and 12th postconceptional week, the period most sensitive to congenital malformation, four delivered live-born children affected with a congenital abnormality (atrial septal defect type II, complex defect of respiratory system, mild pyelectasis because of the stenosis of ureteropelvic junction, congenital inguinal hernia). Two other children had fetal alcohol syndrome and unrecognized multiple congenital abnormality including talipes equinovarus, deformation type, and four minor anomalies. The pregnancy age–specific mean birth weight indicated intrauterine fetal growth retardation, which was confirmed by a dose–response relationship and by the higher rate of low birth–weight newborns. Cognitive status and behavioral scale of exposed children did not indicate neurotoxic effects. Very large doses of chlordiazepoxide used for suicide attempts during pregnancy did not induce a higher rate of congenital abnormalities but were associated with dose-dependent intrauterine growth retardation.

Abstract
Endoscopy during pregnancy raises the unique issue of fetal safety. Endoscopic medications comprise a significant component of fetal risks from endoscopy. Before endoscopy, the gastroenterologist or anesthesiologist should evaluate the potential fetal risks of sedation and analgesia, identify any contraindications to endoscopy, stabilize the maternal medical status as necessary, and correct maternal hypoxia or hypotension. The mother should be informed about the potential teratogenic risks of endoscopic medications during pregnancy. Patients who receive sedation and analgesia should be monitored during endoscopy by continuous electrocardiography, continuous pulse oximetry, and intermittent sphygmomanometry, as well as by the pulse and respiratory rate. General principles of sedation and analgesia during pregnancy include use of the minimal effective dose, avoidance of unnecessary medications, and preferable use of Food and Drug Administration category B medications.

Abstract
Defects attributable to drug therapy represent about 1% of congenital defects of known aetiology. This means that a precautionary attitude and correct use of drugs in fertile, and especially pregnant, women is a feasible form of prevention. Drugs currently in use with proven teratogenic effect number approximately 25, but new pharmaceutical drugs are constantly in preparation. Recognition of a drug-induced teratogenic effect is a complex procedure taking into account not only experimental animal data but also experience in humans. Considering that 40% of pregnancies are not planned, it follows that any drug with known or suspected teratogenic potential must be used only under strict medical control. Also, adequate knowledge on potential teratogenicity of a drug permits modification of therapy before conception. It goes without saying that any drug should be used during pregnancy only if it is essential, and it would be prudent to use only those where adequate information is provided and prior clinical experience is available. Teratology Information Services can assist both physicians and patients when any doubt exists.

Abstract
OBJECTIVE Dependence on alcohol, nicotine, or illicit drugs during pregnancy continues to be a problem of major medical, social, and fetal consequences. The purpose of this systematic review was to summarize current experience that pertains to pharmacotherapy for pregnant women with specific chemical addictions. STUDY DESIGN Studies were identified through Medline and HealthSTAR (1979-2003) that linked specific pharmacotherapy with pregnancy. This article reviews the English language literature for clinical studies that link the 2 conditions. In addition, reference lists of all articles that were obtained were evaluated for other potential citations. RESULTS Pregnant women are excluded systematically from almost all drug trials. Most knowledge about the fetal effects from maternal substance and medication use comes from animal data and from case reports and small clinical series. With the exception of methadone and nicotine replacement, clinical experience with antiaddictive medications in pregnant women is either very limited (alcohol, stimulants) or nonexistent (cannabis, hallucinogens). CONCLUSION Antiaddiction medications are important in the treatment of pregnant women with opioid and nicotine dependence and are of growing importance in the treatment of alcohol and stimulant dependence. Future directions will be toward increasing knowledge about current drug therapy and in developing new antiaddiction medications.

Abstract
The objective of the study was to check the human teratogenic potential of oral chlordiazepoxide treatment during pregnancy at the analysis of pairs of 22,865 cases with congenital abnormalities (CAs) and 38,151 matched healthy controls in the population-based data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities (HCCSCA) between 1980 and 1996. Two hundred and one (0.9%) case mothers and 268 (0.7%) control mothers had chlordiazepoxide treatment during pregnancy, respectively. Our analysis showed higher odds ratio (OR) with 95% confidence interval (CI; 2.5, 1.0-6.0) for chlordiazepoxide use during the 2nd-3rd month of gestation in the group of congenital cardiovascular malformations. However, this association was found when exposure data were based mainly on maternal self-reported chlordiazepoxide treatments (80% in cases and 71% in controls). There was no increase in the rate of any specific congenital cardiovascular malformation type. In conclusion, therapeutic doses of chlordiazepoxide during pregnancy are unlikely to pose a substantial teratogenic risk to the human fetus, although a somewhat higher rate of congenital cardiovascular malformations cannot be excluded.

Abstract
More than 12,000 pregnant patients in the United States per annum have conditions that are normally evaluated by EGD. More than 6000 pregnant patients in the United States per annum have conditions that are normally evaluated by sigmoidoscopy or colonoscopy. About one thousand more have symptomatic choledocholithiasis during pregnancy, which is a strong indication for endoscopic sphincterotomy in nonpregnant patients. Endoscopy during pregnancy raises the unique issue of fetal safety. Endoscopic medications comprise a significant component of fetal endoscopic risks. Safety of EGD during pregnancy has been examined in a case-controlled study of 83 patients, a mailed survey of 73 patients, and 28 case reports. Safety of sigmoidoscopy during pregnancy has been examined in a case-controlled study of 46 patients, a mailed survey of 13 patients, and 10 case reports. Safety of therapeutic ERCP during pregnancy has been analyzed in studies of 23, 10, 6, and 5 patients, and in 32 case reports. These studies suggested that EGD, sigmoidoscopy, and ERCP should be performed when strongly indicated: EGD for significant upper gastrointestinal bleeding, sigmoidoscopy for nonhemorrhoidal rectal bleeding, and ERCP for symptomatic choledocholithiasis when sphincterotomy is contemplated. PEG and colonoscopy are currently considered experimental during pregnancy because of insufficient data on fetal safety. Several cases of PEG and colonoscopy were successfully performed during pregnancy. Performance of endoscopy during pregnancy should increase with further technical refinements, and greater awareness of procedure safety.

Abstract
Although little data exist directly evaluating the utility and safety of endoscopy in the pregnant woman with IBD, it appears to be well tolerated by both mother and fetus, and provides useful clinical information. When performed to evaluate gastrointestinal bleeding, EGD has a high diagnostic yield, while EGD for nausea and vomiting is less informative. In the patient without IBD presenting with hematochezia, unexplained diarrhea, severe abdominal pain, or severe rectal pain, careful sigmoidoscopic examination is indicated, often leading to a diagnosis of new-onset or unsuspected IBD. Likewise, the pregnant IBD patient with worsening symptoms, despite appropriate medical therapy, may also benefit from sigmoidoscopy. Colonoscopy is less often indicated, but can be safely performed in the carefully selected pregnant patient. In all cases obstetrical consultation should be obtained prior to endoscopy, and the risks and benefits of endoscopy to both mother and child should be considered. Close attention should be paid to appropriate drug selection for conscious sedation, and sedation should be administered to provide patient comfort, while avoiding oversedation. Extrapolating from data obtained during endoscopic examination of the pregnant non-IBD patient, fetal monitoring is generally not indicated, although it should be considered for the high-risk or late third-trimester patient. Following these principles assures that endoscopy can be safely performed in the pregnant IBD patient with the best possible outcome for both mother and baby.

Abstract
The issue of prescription of analgesics during lactation is clinically important but also complex. Most of the information available is based on single dose or short term studies, and for many drugs only a single or a few case reports have been published. As great methodological problems exist in the assessment of possible adverse drug reactions in neonates and infants, there is limited knowledge about the practical impact of the, often very low, concentrations found. Nevertheless, some recommendations can be made. Breast-feeding during maternal treatment with paracetamol (acetaminophen) should be regarded as being safe. Short term use of nonsteroidal anti-inflammatory drugs seems to be compatible with breast-feeding. For long term treatment, short-acting agents without active metabolites, such as ibuprofen, should possibly be preferred. The use of aspirin (acetylsalicylic acid) in single doses should not pose any significant risks to the suckling infant. Use of codeine is probably compatible with breast-feeding, although the effects of long term exposure have not been fully elucidated. For propoxyphene, it seems unlikely that the suckling infant will ingest amounts that will cause any detrimental effects during short term treatment. However, it cannot be excluded that significant amounts of the metabolite norpropoxyphene may arise in the suckling infant during long term exposure. Treatment of the mother with single doses of morphine or pethidine (meperidine) is not expected to cause any risk for the suckling infant. Repeated administration of pethidine, in contrast to morphine, affects the suckling infant negatively. Thus, morphine should be preferred in lactating mothers. However, during long term treatment with morphine, the importance of uninterrupted breast-feeding should be assessed on an individual basis against the potential risk of adverse drug effects in the infant. If it is decided to continue breast-feeding the infant should be observed for possible adverse effects. In general, if treatment of a lactating mother with an analgesic drug is considered necessary, the lowest effective maternal dose should be given. Moreover, infant exposure can be further reduced if breast-feeding is avoided at times of peak drug concentration in milk. As breast milk has considerable nutritional, immunological and other advantages over formula milk, the possible risks to the infant should always, and on an individual basis, be carefully weighed against the benefits of continuing breast-feeding.

Abstract
More than 12,000 pregnant patients in the United States per year have conditions normally evaluated by esophagogastroduodenoscopy (EGD). More than 6000 pregnant patient in the United States per year have conditions normally evaluated by sigmoidoscopy or colonoscopy. Endoscopy during pregnancy raises the unique issue of fetal safety, and endoscopic medications comprise a significant component of fetal risks from endoscopy. This article analyzes the safety of endoscopic medications during pregnancy, reviews the literature on the safety of gastrointestinal endoscopy during pregnancy, proposes guidelines for endoscopic indications during pregnancy, and describes modifications of gastrointestinal endoscopy during pregnancy to increase fetal and maternal safety.

Abstract
Diazepam is routinely used in obstetrics in the treatment of maternal eclampsia or as anesthetic induction during deliveries or cesarean sections. We investigated here the effects of perinatal diazepam treatment on the liver of Sprague Dawley rats. From 15th day of gestation to birth pregnant rats were treated daily in the first experimental group (DZ1) with 2.5 mg DZ/kg b.w., s.c., the second (DZ2) with 5 and the third (DZ3) with 10 mg DZ/kg b.w. After birth respective treatment was continued to the pups till 5th day postnatal. One half of pups from DZ2 and control was sacrificed at 12th day, the other were raised to 120th day and then sacrificed. After fixation in formaldehyde serial paraffin sections were processed with proliferating cell nuclear antigen (PCNA), autofluorescence of lipofuscin and Elastica v. Gieson staining. Livers from 12 day old rats showed increased levels of PCNA marked hepatocytes and lipofuscin containing cells. Livers from 120 day old animals exhibited increased levels of PCNA cells especially with weakly stained nuclei, the number of lipofuscin containing cells were decreased in DZ1 and DZ2 but reached in DZ3 the similar number as control. Statistical analysis showed that quantification of Kupffer cells lacked significance. To conclude livers of 12 day old animals demonstrated a stimulated DNA synthesis and an accumulation of nondegradable residues. Livers from 120 day old rats demonstrated an increase in number of potentially proliferating hepatocytes by increased levels of weakly stained PCNA nuclei. At lower dosage DZ seems to inhibit lipofuscinogenesis, at highest dosage DZ accumulates non-degradable residues. Elastica v. Gieson staining was not suitable to quantify Kupffer cells with certainty.

Abstract
The long-term consequences of neonatal exposure to diazepam (DZP) on behavioral abilities and local cerebral glucose utilization (LCGU) in 12 brain regions involved in the control of memory and anxiety were studied in adult rats. Rat pups received a daily subcutaneous injection of 10 mg/kg DZP or of the dissolution vehicle from postnatal day (P) 2 to 21. Learning and memory were tested in P60-P70 rats over 5 consecutive days in a T maze and an eight-arm maze while anxiety and reaction to novelty were tested in a two-compartment box with a two-step staircase on the enriched side. LCGU was measured in the P60 rat by the quantitative autoradiographic [14C]deoxyglucose method. In the T maze, when performed without delay between the two trials, the rate of alternation was significantly lower in DZP- than in vehicle-exposed rats on the first 2 days of testing and similar in both groups on days 3-5. In the procedure with a 30 s intertrial delay, the rate of alternation was similar in DZP- and vehicle-treated rats on all days of testing. In the eight-arm maze, DZP-treated rats were more active, i.e., entered more arms per minute than control animals. The number of arms entered before the first error was lower on day 1 and higher on day 3 in DZP- compared to vehicle-exposed rats. In the two-compartment box, DZP-treated rats crossed more often and spent more time than controls on the lower step of the staircase while control rats made more rearings and spent more time than DZP-exposed rats in the well protected corner of the box. LCGU were decreased by early DZP exposure in six regions which were mammillary body, septum, visual and prefrontal cortices, dorsomedian caudate nucleus and mediodorsal thalamus. In conclusion, postnatal DZP treatment induced at adulthood an increase in activity, a delay in task acquisition but no learning-memory impairment and reduced the level of anxiety allowing active responding to novelty. These quite subtle behavioral changes were accompanied by discrete metabolic decreases in regions mediating anxiety, reflecting a change in the level of anxiety and emotionality.

Abstract
For most agents with CNS activity, there are limited data regarding their safety in breastfeeding. Any decision to institute treatment for a neurological or psychiatric disorder must weigh the benefits of maternal treatment against the potential harm to the breastfeeding mother of withholding medication which may improve her illness. For the neonate, one must balance the risk of medication exposure against the benefit of receiving breast milk. Most tricyclic antidepressants can be used in lactating women. Because of the limited data, selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors should only be used with due consideration of the potential adverse effects. Breastfeeding is best avoided by women who require lithium therapy, because of both the immature excretory systems in the infant and relatively high doses received by the infant. There is little information about the safety of antipsychotic medications in breastfeeding. Concerns include toxicity and abnormal neurological development in the infant. These agents may be used with caution. Most agents which cause depression of the CNS, including opiates and sedatives, can be used in small doses and for short courses in breastfeeding mothers. Most anticonvulsants can be used in lactating women. Reference texts and consultation with experts are useful adjuncts to discussion of the risks and benefits of therapy with the patient. The scope of this review is limited to drugs with therapeutic uses, thus drugs of abuse are not discussed, nor are caffeine and alcohol (ethanol).

Abstract
The placenta was classically considered a barrier, but in 1957 this notion was shattered. This organ is only a selective filter and metabolic site. In this review, the placental transfer of the top 17 substances of abuse are analyzed. In the National Library of Medicine only 41 papers that documented placental transfer of the major substances of abuse could be located, and these data excluded approximately one-sixth of the most commonly abused substances. Nonetheless, it was possible to evaluate placental transfer of all substances of abuse based on their physical chemical properties. It is with despair that it must be reported that virtually all substances of abuse freely cross the placenta, exposing the embryo/fetus to whatever substances the mother may be using.

Abstract
Although there are a number of studies and individual case reports concerning the use of benzodiazepines in human pregnancy, the data concerning teratogenicity and effects on postnatal development and behaviour are inconsistent. There is evidence from studies in the 1970s that first trimester exposure to benzodiazepines in utero has resulted in the birth of some infants with facial clefts, cardiac malformations, and other multiple malformations, but no syndrome of defects. Diazepam and chlordiazepoxide are amongst the drugs most frequently implicated in the earlier studies. However, data from later studies provide no clear evidence of significant increase in either the overall incidence of malformations or of any particular type of defect. Many of the women included in these studies has psychiatric illnesses, epilepsy, or diabetes all of which have an intrinsic risk in pregnancy, and some were on multidrug therapy. Medical-obstetric histories and family history of malformations were not always presented in the publications, which makes assessment of risk associated with benzodiazepine use per se difficult. Nevertheless, in most of the studies involving first trimester use of benzodiazepines, the majority of infants were normal at birth and had normal postnatal development. Late third trimester use and exposure during labour seems to be associated with much greater risks to the fetus/neonate. Some, but by no means all infants exposed at this time, exhibit either the floppy infant syndrome, or marked neonatal withdrawal symptoms. Symptoms vary from mild sedation, hypotonia, and reluctance to suck, to apnoeic spells, cyanosis, and impaired metabolic responses to cold stress. These symptoms have been reported to persist for periods from hours to months after birth. This correlates well with the pharmacokinetic and placental transfer of the benzodiazepines and their disposition in the neonate. However, there has been no significant increase in the incidence of neonatal jaundice and kernicterus in term infants. The prolonged use of benzodiazepines throughout pregnancy raised the concern that there may be altered transmitter synthesis and function, leading to neurobehavioural problems in the children. In approximately 550 children who were followed up for various times up to four years of age, there is no increase in either the malformation rate or adverse effects on neurobehavioural development and IQ. Although some of the data indicate that a small number of children were slower to develop during the first year or so, they did exhibit catch up growth and most had developed normally by four years of age. Where developmental deficits persisted, it was not possible to prove a cause-effect relationship with benzodiazepine exposure. These children were often from families where there was maternal illness requiring prolonged drug therapy or where there were social problems. It is important to consider poor environmental and social factors when assessing the possible prenatal influence of the benzodiazepines on the postnatal health and development of the child. There is evidence that clonazepam, clorazepate, diazepam, lorazepam, midazolam, nitrazepam, and oxazepam are excreted into breast milk. The published data indicate that the levels detected in breast milk are low; therefore, the suckling infant is unlikely to ingest significant amounts of the drug in this way. Problems may arise if the infant is premature or has been exposed to high concentrations of drug either during pregnancy or at delivery.

Abstract
This review is an update on anesthetic agents and their excretion into breast milk; it presents the reported effects on suckling infants, and discusses the precautions which should be considered. For most anaesthetic agents, there is very sparse information about breast milk excretion and even less published knowledge about the possible effects on the suckling infant. Generally, when an anaesthetic agent is given on a single-dose basis, there is no evidence that it is excreted in breast milk in clinically significant amounts, even if there are detectable concentrations of the drug in the milk. Most anaesthetics are rapidly cleared from the mother, and, consequently, it should be possible to allow suckling as soon as practically feasible after surgery. However, repeated administration of certain opiates and benzodiazepines has been reported to cause adverse effects in neonates, with premature neonates apparently being more susceptible. Thus, in long-term treatment with these drugs, the importance of uninterrupted breast feeding should be assessed against possible adverse drug effects in the neonate.

Abstract
OBJECTIVE To present a procedure for establishing treatment guidelines during pregnancy and, as an application of the method, the recommendations for treatment of pruritus. DESIGN A preliminary survey was carried out among participants of the study group to determine drug choices for treatment of pruritus during pregnancy. Literature data on the selected drugs were analyzed. Recommendations for treatment were proposed, taking into account for most efficient agents and the least toxic for the fetus. This draft was submitted to all participants of the study group; criticism and suggestions were gathered. A new draft was evolved and repeatedly submitted to participants until consensus was reached. SETTING Study group set up in southwestern France, with the help of national experts. PARTICIPANTS Forty-three general practitioners, six gynecologists and/or obstetricians, five pharmacologists, two dermatologists, and an embryologist. RESULTS The main recommendations for treatment of pruritus during pregnancy are to begin with topical treatment; emollient bath additives, moisturizing cream, talc. If insufficient, a systemic treatment should be added. Antihistamines are prescribed first: hydroxyzine or dexchlorpheniramine is used during the first 2 months. From the third month, the same agents can be used, as can mequitazine. The duration of treatment can be up to 10 days. The group's second choice was benzodiazepine (oxazepam) as second-line treatment. CONCLUSIONS Strategies for treatment of diseases during pregnancy are not always well defined. For many common diseases, very few data are available concerning drug use in pregnant women. The study group, based on consensus among participants, proposed treatment guidelines.

Abstract
A critical evaluation of anaesthetic agents in the puerperium is difficult because systematic, relevant studies are still lacking. Current knowledge of the effects of different agents used in labour and caesarean section indicates that significant residual effects on the mother and newborn are limited. In the early puerperium, based on physiological and/or hormonal changes, the mother could be more sensitive to inhalational anaesthetic agents and local analgesics. To date there is no evidence that any anaesthetic agent is excreted in breast milk in clinically significant amounts when given as a single dose. The only exception is perhaps in the case of very premature neonates whose mothers have had multidrug therapy before labour. Even then the importance of breast milk should be carefully assessed against possible adverse drug effect. However, repeated administration of long-acting benzodiazepines and continuous epidural administration of pethidine (meperidine) can have adverse effects on the neonate. The essential conclusion of this review is that breast-feeding is best. The different anaesthetic agents are excreted in the milk in amounts so low that detrimental effects on the neonate should not be expected.

Abstract
Benzodiazepines are among the most frequently prescribed drugs worldwide. This popularity is based not only on their efficacy but also on their remarkable safety. Pure benzodiazepine overdoses usually induce a mild to moderate central nervous system depression; deep coma requiring assisted ventilation is rare, and should prompt a search for other toxic substances. The severity of the CNS depression is influenced by the dose, the age of the patient and his or her clinical status prior to the ingestion, and the coingestion of other CNS depressants. In severe overdoses, benzodiazepines can occasionally induce cardiovascular and pulmonary toxicity, but deaths resulting from pure benzodiazepine overdoses are rare. Quantitative determinations of benzodiazepines are not useful in the clinical management of intoxicated patients since there is no correlation between serum concentrations and pharmacological and toxicological effects. Benzodiazepine overdoses occurring during pregnancy rarely induce serious morbidity in mothers or fetuses, although large doses administered near delivery can induce respiratory depression in neonates. The teratogenic potential of benzodiazepines remains controversial, but is probably small if it exists at all. There is clear evidence that the prolonged use of even therapeutic doses of benzodiazepines will lead to dependence. The risk of developing significant withdrawal symptoms is related to dosage and duration of treatment. Prevention of gastrointestinal absorption should be initiated in all intentional benzodiazepine overdoses. Forced diuresis and dialysis techniques are not indicated since they will not significantly accelerate the elimination of these agents. Intravenous administration of flumazenil, a pure benzodiazepine antagonist, effectively reverses benzodiazepine-induced CNS depression.

Abstract
Prenatal exposure to benzodiazepines may lead to developmental abnormalities in humans and animals. To assess the behavioral and neurochemical effects of such exposure, pregnant mice were treated with lorazepam, 2 mg/kg/day, from days 13-20 of gestation, and open-field activity was assessed in offspring at 3 and 6 weeks of age and the function of GABAA receptors at 6 weeks of age. Activity was increased in mice exposed to lorazepam, compared to untreated or vehicle-treated controls at 3 weeks, but was unchanged at 6 weeks. Muscimol-stimulated uptake of chloride was decreased in lorazepam-treated mice, compared to controls, with a decrease in maximum uptake but no change in the EC50 for muscimol. Concentrations of lorazepam in maternal plasma and brain showed a similar brain:plasma ratio as previously reported and concentrations in fetal brain were about 50% of maternal levels. Lorazepam persisted for 48 hours after birth in dams but not in the offspring. These results indicate persistent behavioral and neurochemical alterations after prenatal exposure to lorazepam. This model may be useful in assessing other effects of prenatal exposure to benzodiazepine.
