Solvent abuse in pregnancy: a perinatal perspective.

OBJECTIVE: To review the scope and sequelae of solvent abuse in women presenting to a Manitoba teaching hospital. METHODS: Fifty-six patient charts with a diagnosis of solvent abuse in pregnancy were identified through computer search in the medical records of Winnipeg Health Sciences Centre, General Hospital. These charts were reviewed and data obtained from birthing records and associated pediatric charts. RESULTS: Renal tubular acidosis was diagnosed in three patients (5.3%). Two patients (3.6%) had adverse neurological sequelae. One patient was diagnosed with brain damage, including expressive aphasia. Twelve patients (21.4%) delivered preterm infants. Nine infants (16.1%) had major anomalies. Seven infants (12.5%) had fetal alcohol syndrome (FAS)-like facial features. Six neonates (10.7%) had hearing loss. CONCLUSION: Substance abuse in pregnancy is associated with severe maternal and neonatal sequelae. Physicians must be aware of this increasing problem in the obstetrical population and assistance should be offered to each woman, ideally before a woman becomes pregnant, but at least at the first contact a pregnant woman makes with the health care community.

[Management of mono-amnion twin pregnancy].

There have been only a few reports on monoamniotic twin pregnancies from the period of modern perinatology. Consequently, available recommendations about the management of these high-risk pregnancies are uncertain. In this study, we present the management and the outcome of three monoamniotic twin pregnancies and two further pregnancies with acardiac acephalus twin in comparison to other case reports and case series from the literature. Practical ways of caring for these high-risk pregnancies are outlined, emphasising the continuous search for entanglement of umbilical cord by ultrasound and cardiotocography. The special importance of intensified cardiotocographic monitoring is demonstrated.

[Labor without prenatal care--an unnecessary challenge].

A group of 431 patients who had given birth, but had not attended regular check-ups during their pregnancy, are compared with a cumulative comparative group. The data is from a databank, belonging to the Swiss gynaecological working group. The following results are striking: Very young women, relatively older childbearing women, a noticeably high number of unmarried women and women from the Mediterranean countries. The number of women with heavy nicotine abuse is significant. The general progress of the pregnancy is however not noticeably different from the comparative group. The premature birth rate is higher in the group without pregnancy check-ups, as are birth deficiences and clinical foetal distress. Particularly noticeably is the high number of perinatal deaths. The pointlessness and the possible reasons for lack of regular pregnancy check-ups are discussed.

Management of UTIs during pregnancy.

This article summarizes the pathophysiology, patient presentation, diagnostic testing, and current treatment modalities for pregnant women presenting with urinary tract symptoms in pregnancy. Urinary tract infection is a common health problem, affecting millions of people each year. However, this seemingly benign condition may have serious consequences if it occurs during the course of a woman's pregnancy, and if untreated could lead to pyelonephritis, preterm labor, or Group B Streptococcal infection in the newborn. Thus, the prevention, early detection, and prompt treatment of urinary tract infections in pregnancy have become essential components of prenatal care.

Acute myocardial infarction in pregnancy and the puerperium: a population-based study.

OBJECTIVE: To estimate the population-based incidence and pregnancy outcomes of acute myocardial infarction (MI) in pregnancy. METHODS: Maternal and newborn hospital discharge records were linked to birth/death certificates for the 10-year period January 1, 1991, to December 30, 2000, for the majority (98%) of deliveries in California. This database was searched for the diagnosis of acute MI, demographic characteristics, and pregnancy outcomes. Patients were divided into 4 groups: antenatal diagnosis, intrapartum diagnosis, up to 6-week postpartum diagnosis, and those without the diagnosis of acute MI. All groups were compared by Student t test or chi(2) or both, where appropriate. RESULTS: A total of 151 women had an acute MI during the antepartum (38%), intrapartum (21%), or 6-week postpartum (41%) period, giving an incidence rate of 1 in 35,700 deliveries. The incidence rate increased over the study period. The maternal mortality rate was 7.3%, and maternal death only occurred in women with an acute MI before or at delivery (P < .01). Compared with women who did not have an acute MI, those with one were more likely to be older (30% were older than 35 years compared with 10%), multiparous (78% compared with 61%), non-Hispanic white (40% compared with 35%) or African Americans (15% compared with 7%). All measures of maternal and neonatal morbidity were increased in the acute MI group compared with those without an acute MI. Multivariate analysis identified chronic hypertension, diabetes, advancing maternal age, eclampsia, and severe preeclampsia as independent risk factors for acute MI. CONCLUSION: Acute MI during pregnancy remains a rare event, with significant maternal, fetal, and neonatal morbidity and mortality and maternal mortality limited to the antepartum and intrapartum period.

Low serum zinc concentrations in pregnancy, results of investigations and treatment.

Twenty gravidae in whom the serum zinc concentration was less than 11.5 mumol/1 were investigated. Haemoglobin, serum vitamin B-12, serum folate, serum copper, and bone marrow smears were assessed. Thirteen showed haemoglobin concentrations below 110 g/1 and in 7 of them the cause of this anaemia was not found. Histological investigations indicated increased intramedullary cell destruction. Eight women selected at random were referred for further investigation including tests of renal and hepatic function, serum protein analyses, tests of haemolysis, and estimation of zinc and oestriol excretion in urine. The low serum zinc concentrations received no probable explanation other than zinc deficiency. Seven gravidae were treated with 90 mg Zn2+ daily as zinc sulphate by mouth during the latter part of pregnancy. Zinc excretion in urine was low and increased significantly (p less than 0.005) after one week's therapy. The serum zinc also increased (p less than 0.05). Zinc therapy gave no reticulocytosis within 8-12 days. Three women reported spontaneously an improvement in sense of taste. Five of 20 gravidae had dysmature infants. Heavy bleeding occurred at delivery in 6 cases, possibly secondary to impaired uterine contractility. Seven women who received zinc therapy had all normal deliveries, but labour was prolonged in one. No side effects of zinc therapy were noted except for nausea in one case. Further trials of zinc supplementation in larger series of women with low serum zinc concentrations during pregnancy seem to be justified.

An assessment of key aetiological factors associated with preterm birth and perinatal mortality.

The 4 main causes of preterm births in 303 women with consecutive deliveries in Flinders Medical Centre were premature rupture of the membranes (39%), spontaneous preterm labour (22%), pregnancy-induced hypertension (17%) and antepartum haemorrhage (12%). Premature rupture of the membranes occurred with equal frequency in singleton and multiple pregnancies and there was no difference in the frequency of this cause between the pregnancies with live outcomes and those with perinatal deaths. Spontaneous preterm labour was more common in multiple pregnancies (39%) than in singleton pregnancies (22%). One in 3 of the preterm births and 79% of the pregnancies with perinatal deaths occurred at less than 32 weeks' gestation. As it is unlikely that any single obstetric and social intervention will be able to reduce these causes of preterm birth research must continue to find markers to predict premature rupture of the membranes and spontaneous preterm labour.

Antenatal care in developing countries. What should be done?

Development of antenatal care from the beginning of the 20th century and its relation to perinatal mortality in developed countries is presented. The role of socioeconomic factors, new diagnostic and therapeutic procedures, extended indications for cesarean section and of neonatal intensive care is also stressed. In the West- and Middle-European countries by the introduction of antenatal care the perinatal mortality (PNM) rate decreased from about 60.0@1000 in the years 1920-1930 to about 40.0@1000 in 1950s. Further decrease to about 25.0@1000 in the 1970s was conditioned by an increase of number of antenatal visits and by extended indications for cesarean section. New technologies (amnioscopy, pH.metry, cardiotocography and ultrasound examinations) decreased the PNM rate to about 13.0@1000 in the year 1980. Regional organization with neonatal intensive care units decreased PNM rate to low values of 5.0-9.0@1000. The echo of the number of antenatal visits to PNM rate is illustrated on 36,855 deliveries at the University Clinic in Zagreb. In developing countries maternal and perinatal mortality is very high. The reason for that is a bad socioeconomic background and a lack of organized antenatal and perinatal health care system. The policy to decrease maternal and perinatal mortality is presented: the improvement of antenatal booking and of the number of prenatal visits of pregnant women; their childbearing under professional assistance. The organizing of maternity health care should be different from country to country, from region to region, respectively.

Meconium stained amniotic fluid is associated with maternal infectious morbidity in pre term delivery.

The purpose of the study was to determine if intra partum meconium stained amniotic fluid (MSAF) is associated with infectious morbidity in women with pre term delivery. The study group was composed of 89 women with pre term delivery and MSAF. The control group comprised 89 women with pre term delivery and clear amniotic fluid, matched for maternal age, gravidity, parity, gestational age, rate of premature rupture of membranes, breech presentation and mode of delivery. The parameters of maternal infectious morbidity were compared between the two groups during pregnancy, delivery and puerperium. The prevalence of recurrent urinary tract infections was significantly higher in the study group than those in the control group, 7.8% (7/89) vs. 0% (0/89), respectively (p = 0.02). During delivery women with MSAF had a significantly higher rate of clinical chorioamnionitis than women without MSAF, 6% (6/89) vs. 0% (0/89), respectively (p = 0.03). Histological chorioamnionitis was also significantly higher in patients with intra partum MSAF, as compared to those the clear amniotic fluid, 11.2% (10/89) vs. 0% (0/89), respectively (p = 0.03). In addition, women in the study group had a significantly higher post partum infectious morbidity rate and endometritis than women in the control group [52.8% (47/89) vs. 37.1% (33/89) (p = 0.05); 18% (16/89) vs. 7.8% (7/89) (p = 0.03), respectively]. We conclude that intra partum MSAF should be considered as a potential marker for infectious morbidity in women with pre term labor and delivery.

Maternal risk factors for preterm birth and low birthweight in Cape Verde.

BACKGROUND: Fifteen years after the implementation of an antenatal risk screening program in Cape Verde, the first assessment of an association between maternal obstetric characteristics and preterm birth or low birthweight (LBW) infants was undertaken. METHODS: A cohort of 353 systematically selected antenatal clinic attenders in the county of Praia, Cape Verde, was studied prospectively during the period October 1991 through December 1992. The cohort was followed past the perinatal period and information was obtained according to a pretested structured questionnaire. In the analysis of preterm birth and LBW, multiple logistic regression was listed to estimate the relative risks of ll background variables. RESULTS: The prevalence of preterm birth (<37 gestational weeks) was 12%, and the prevalence of LBW infants was 8%. Low birthweight (<2500 grams) was significantly associated with low maternal age (< or = 19 years, RR=3.7); nulliparity (RR=5.2) and obstetric history of previous LBW infant (RR-6.5). The risk of preterm birth was significantly increased if the woman had an obstetric history of hypertension or convulsions (RR=2.6). CONCLUSIONS: In the setting studied, teenage women and women with previous pregnancy hypertension should be given selective attention in antenatal care to achieve improved pregnancy outcome. Primary prevention is needed to lower the prevalence of teenage pregnancies.
