This study aimed to analyse perinatal outcomes in ofloxacin-exposed pregnancies. This prospective study was conducted on 143 singleton pregnancies between January 2001 and April 2014, after oral ofloxacin exposure in the first trimester. A total of 33 exposed mothers were compared with 110 age-matched controls who were not exposed to teratogen. The mean maternal age was 31.4 ± 3.6 years, and the median gestational age was 4.1 weeks at the exposure. No significant differences were observed in either gestational age or in the foetal ultrasonographic long bone length between the exposed and control groups. Spontaneous abortions occurred without a significant difference (6.1% versus 10.0%, p = .733). In addition, no significant differences were found in either the stillbirths or in the major birth defects between the exposed and control groups (0% versus 2.0%, p = 1.000 and 0% versus 4.0%, p = .572, respectively). Ofloxacin has no significant effect on perinatal outcomes. Impact statement What is already known on this subject? Ofloxacin and other quinolones are avoided during pregnancy because of concerns about cartilage toxicity. But we do not find human data reporting such toxicity in a case report. What the results of this study add? Previous studies were designed for evaluation of just congenital anomaly. But in this study, we measured the fetal long bone length to replace for evaluation of fetal cartilage toxicity. In fetal stage, we can not measure the cartilage of fetus. so we measure fetal long bone length for evaluation that ofloxacin might influence to fetal cartilage growth. Even though this sample size is small. this results will be helpful to counsel pregnant women who exposed to ofloxacin during pregnancy.

Objectives: The aim was to investigate the effect of -maternal smoking exposure assessed by urinary tobacco-specific nitrosamine metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-a1-butanol (NNAL) with adverse pregnancy outcomes., Methods: A total of 251 pregnant women were recruited. Urinary cotinine and NNAL were measured. Participants' sociodemographics were obtained by questionnaire and pregnancy outcomes were collected by charts review after delivery., Results: The prevalence of smoking was 8.4% (21 of 249), 1.2% (3 of 241), and 3.7% (9 of 241) in pregnant women according to questionnaire, cotinine, and NNAL, respectively. As compared with questionnaire positivity and cotinine levels, women with positive NNAL were independent determinants for spontaneous abortion (adjusted OR 12.357, 95% CI 2.053-74.368), preterm birth (adjusted OR 22.239, 95% CI 3.737-132.357), and small for gestational age (adjusted OR 6.915, 95% CI 1.385-34.524)., Conclusions: Urinary NNAL might be a useful biomarker in detection of maternal smoking status in association with adverse pregnancy outcomes. Use of this marker in preconception and pregnancy counselling before planning pregnancy may allow prevention of several adverse pregnancy outcomes., (© 2018 S. Karger AG, Basel.)

It is accepted that blood phosphatidylethanol (PEth) concentrations are reliable biomarkers of ethanol (alcohol) exposure. We therefore conducted a preliminary study to test the hypothesis that elevated blood PEth concentrations can help to identifying women with prenatal alcohol exposure who are at higher risk of adverse pregnancy outcomes. The study included 35 first-trimester pregnant women who self-reported alcohol ingestion and had PEth blood concentration ⩾4 nM at recruitment. As a control group, 233 first-trimester pregnant women who self-reported as being either abstainers or light alcohol drinkers and had blood PEth concentrations <4 nM, were also included. All participants were followed up until completion of their pregnancies. Women with prenatal alcohol exposure and PEth concentrations ⩾4 nM had a risk ratio of spontaneous abortions of 3.21 (95%CI 0.93-11.06; P=0.074). Because of the potential implications in the prenatal care of women reporting risky alcohol exposure, the preliminary results from the present study indicate the need for testing the hypothesis in a more definitive approach., (Copyright © 2015 Elsevier Ltd.

Objectives: Little is known on how the dose and timing of exposure co-influence the cumulative concentration of fatty acid ethyl esters (FAEEs) in meconium. The objective of the study was to assess the cumulative concentration of FAEEs in meconium as a biomarker of light, moderate, or heavy prenatal alcohol exposure occurring at either first, second, or third trimesters of pregnancy., Methods: History of prenatal alcohol exposure was obtained in the 34th week of gestation from 294 pregnant women. Meconium was collected from their babies within the first 6 to 12 h after birth and examined for the presence of nine FAEEs., Results: No significant differences were identified between the cumulative levels of FAEEs in the meconium from the babies born to abstainers and those born to mothers with history of light-to-moderate prenatal alcohol exposure during their pregnancy., Conclusions: Light-to-moderate prenatal alcohol exposure cannot be reliably predicted by the cumulative FAEE concentrations in meconium of exposed babies. A cumulative FAEE level of >10 nmol/g would be required to consider that prenatal alcohol exposure during the second to third trimesters occurred at risky levels in the absence of reliable maternal history of ethanol exposure., (© 2014 John Wiley & Sons, Ltd.)

No information is currently available on the safety of the aminoglycoside ribostamycin in pregnancy. We aimed to study the pregnancy outcome of women inadvertently exposed to ribostamycin during the first trimester of pregnancy. In a prospective cohort study, 102 women inadvertently exposed to ribostamycin during the first trimester of pregnancy and an age- and gravidity-matched control group, were enrolled. Study outcomes were gestational age at birth, major and minor malformations, and birth weight. Fetal outcomes were evaluated in 85 women inadvertently exposed to ribostamycin during the first-trimester of pregnancy and in 170 control subjects. Newborns were clinically examined at birth by a neonatologist and by imaging studies if any suspicious abnormalities were noted. There were 4/85 (4.9%) babies born with major malformations in the exposed group and 3/170 (1.8%) in the control group (P=0.7). Gestational age at delivery, rate of minor anomalies, rate of preterm births, and birth weight were not different between groups. In conclusion, similar to what is reported for other aminoglycoside, exposure to ribostamycin during the first-trimester of pregnancy does not appear to increase the risk of adverse fetal outcomes.

Background: We aimed to investigate the risk factors associated with unintended pregnancies as well as the association between unintended pregnancies and potential teratogenic exposures., Methods: A cross-sectional survey was performed among women attending the Maternity School of the Samsung Cheil Hospital and Women's Health Care Center in Seoul, Korea. Demographic data, obstetric history, socioeconomic status, intention to become pregnant, and exposure to potential teratogens were obtained., Results: A total of 1354 women with median age of 29 years and median gestational age of 29 weeks were included. Of these, an educational level above high school was 74.2%, primigravida was 77.3% and unintended pregnancy was 48%. In the logistic regression analysis, women younger than 24 years of age had a relative risk (RR) of 2.5 (95% confidence interval [CI], 1.3-4.7) of having an unintended pregnancy and women with lower household monthly income level had a RR of 1.3 (95% CI, 1.0-1.6). Women with unintended pregnancies had an RR of 1.9 (95% CI, 1.5-2.5), 3.0 (95% CI, 2.0-4.5), 1.5 (95% CI, 1.0-2.3), 2.9 (95% CI, 1.1-7.2), and 2.0 (95% CI, 1.62.4) of being exposed to alcohol, medications, cigarette smoking, X-rays, or to any of these, respectively, during the first trimester of pregnancy., Conclusions: Unintended pregnancies are more likely to occur among young women with a lower household monthly income level. Prenatal counseling should be especially recommended for women with unintended pregnancies in order to evaluate whether they have been exposed to potential teratogenic agents., ((c) 2005 Wiley-Liss, Inc.)

This study aimed to evaluate pregnancy outcomes of women who were inadvertently exposed to levosulpiride in early pregnancy. All 162 consecutive singleton pregnant women counselled through the Korean Motherisk Program, Cheil General Hospital, between April 2001 and April 2014, on teratogenic risk after inadvertent exposure to levosulpiride in early pregnancy were enrolled in this study. The women were exposed to levosulpiride at median 4.8 gestational weeks. The rate of miscarriage was not significantly different between groups (9.2% in those exposed and 5.5% in the non-exposed; p = .084). The rate of major malformations was not significantly different between exposed (2.7%) and non-exposed pregnancies (4.4%) (p = .481). All other pregnancy outcomes between the two groups were comparable (p > .05). Our data suggest that levosulpiride causes no significant adverse effects on pregnancy outcomes and therefore may be not a major teratogen. [ABSTRACT FROM AUTHOR]
