Prenatal and perinatal factors associated with isolated oral clefting.

OBJECTIVE: To describe medical service utilization and maternal morbid conditions of women who carry offspring with oral clefts (OCs), to describe maternal and offspring complications during birth, and to evaluate postnatal characteristics of their newborns with isolated OCs. METHODS: Two thousand four hundred thirty-seven patients with isolated OCs and 4871 unaffected matched controls meeting inclusion criteria were selected from the U.S. Natality database for 1997. Matching variables were mother's and father's race and child's race, sex, county of birth, and month of birth. Patients and controls were compared in terms of maternal demographic characteristics, gestational complications, physical characteristics of the newborns, maternal exposure to potential risk factors, and adequacy of prenatal care. RESULTS: Although the quality of care was very good in both groups, low gestational age, low birth weight, and low 5-minute Apgar score are more frequent among newborns with OCs than in unaffected controls. Mothers of offspring with OCs are at increased risk, compared with mothers of controls, of having hydramnios or oligohydramnios, eclampsia, and abruptio placenta. Obstetric procedures, such as amniocentesis, electronic fetal monitoring, induction of labor, tocolysis, and ultrasound, and repeat cesarean deliveries are more frequent among mothers of patients than those of controls. At birth, newborns with isolated OCs are at risk of having hyaline membrane disease and of requiring assisted ventilation, independently of gestational age. CONCLUSION: The results of this large population-based, case-control study suggest that the presence of an OC in the offspring is associated with increased risk for prenatal and perinatal complications in the mother.

Acute renal failure in obstetric complications.

Early postpartum disseminated intravascular coagulation (DIC) was demonstrated by serial coagulation studies in 10 cases of acute renal failure (ARF) following obstetric complications (6 abruptio placentae, 3 retained placental fragments, 1 prolonged intrauterine fetal death). DIC abated within 48 hours irrespective of the therapeutic schedules employed. Renal damage was evidenced by a varying number of days of oligoanuric (6 cases) or polyuric (4 cases) ARF which always required dialytic treatment. Full renal recovery occurred in 9 cases. One patient died and no histological studies were performed. Renal damage seemed to correlate less with DIC than with the degree of anemia and shock.

Blows to the maternal abdomen causing fetal demise: report of three cases and a review of the literature.

Traumatic abruption results in 6% of third-trimester gravidas who are hit or kicked in the abdomen during assaults. Three cases are presented in which blows inflicted to the abdomen of pregnant women in their third trimester resulted in the death of the fetus due to abruptio placentae. Two cases were domestic altercations while one was a third-party criminal assault. In all cases the gravida herself escaped significant intra-abdominal injury, and external abdominal findings were minimal. The clinical signs were a history of loss of fetal movements shortly after the assault and loss of fetal heart tones within hours after the assault. One patient had vaginal bleeding; one had uterine contractions. In the cases of domestic abuse, both women initially gave false histories of how the injury occurred.

Preterm labor and accidental hemorrhage after disopyramide therapy in pregnancy. A case report.

BACKGROUND: Treatment of arrhythmias during pregnancy is complicated by concerns about the safety of antiarrhythmic therapy. This is the first case report of preterm labor and abruptio placentae following the administration of disopyramide during pregnancy. CASE: A 26-year-old woman, gravida 2, para 1, was diagnosed as having Wolff-Parkinson-White syndrome during the third trimester of pregnancy. Recurrent episodes of supra-ventricular tachycardia were refractory to medical therapy and required repeated direct current cardioversion. Administration of disopyramide led to the initiation of painful uterine contractions and accidental hemorrhage. CONCLUSION: Caution must be exercised during the use of disopyramide during pregnancy, and intensive monitoring should be instituted to avoid adverse maternal and fetal effects.

Influence of chorioamnionitis on long-term prognosis in low birth weight infants.

The contribution of obstetric management to quality of life of surviving low birth weight infants is unclear. A possible association between maternal chorioamnionitis and development outcome was evaluated. One hundred twenty-seven mother/infant pairs with infant birth weight less than 2000 g were studied. The antenatal course was complicated by chorioamnionitis, premature rupture of membranes without chorioamnionitis, premature labor, or abruptio placenta. Analysis of variance was performed using these four diagnosis groups. After potentially confounding variables were taken into account, the overall difference in the four groups in Mental Development Index (Bayley Scales) was borderline (P = .138). However, significant differences remained between the group with chorioamnionitis and the group with premature rupture of membranes without chorioamnionitis (P = .017). The potential advantage of leaving infants in utero after premature rupture of membranes may be offset by disadvantage of chorioamnionitis with respect to future development in surviving infants.

Severe preeclampsia at <25 weeks of gestation: maternal and neonatal outcomes.

OBJECTIVE: The purpose of this study was to determine maternal and neonatal outcomes of women who were delivered because of severe preeclampsia before 25 weeks of gestation. STUDY DESIGN: We used a computerized database to identify 3800 women with preeclampsia among 35,937 deliveries from 1991 to 1997. Of these, 39 women (1%) with severe preeclampsia were delivered before 25 weeks of gestation. We abstracted outcomes in these women and their newborns. RESULTS: All 39 women had severe preeclampsia as defined by clinical and/or laboratory criteria. Thirty-three of the 39 women had severe-range hypertension. Twenty-one women (54%) experienced morbidity that included abruptio placentae (n = 5), HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome (n = 9), renal insufficiency (n = 5), and eclampsia (n = 3). No women required dialysis or intensive care unit admission, and none of the women died. All maternal morbidities reversed after delivery. Twenty-two infants (55%) were live-born. Only 4 infants (10%) survived, all with severe handicaps. CONCLUSION: In women with severe preeclampsia before 25 weeks of gestation, delivery is associated with minimal short-term maternal morbidities, although neonatal morbidity and death are appreciable.

Eclampsia. I. Observations from 67 recent cases.

Sixty-seven cases of eclampsia were managed from 1977 to 1980, for an incidence of 1 in 310 deliveries. Eighty-four percent of patients were nulliparous and 82% had received some prenatal care. Prior to convulsion, 14 patients (21%) had a diastolic blood pressure below 90 mmHg, 39% had no edema, and 21% had no proteinuria. Thirty-seven patients (55%) had their first convulsion in the hospital. Eight patients had convulsions while receiving magnesium sulfate therapy. Convulsions occurred post partum in 25 patients (37%). In 11 patients the onset of eclampsia occurrred 3 to 11 days after delivery. The total perinatal mortality was 8.6% for all cases of eclampsia. Excluding postpartum cases, perinatal mortality was 13.3%, but was only 5% for those fetuses alive on admission to the perinatal center. Abruptio placentae was present in 9 cases and accounted for 4 of the 6 perinatal deaths. The high incidence of eclampsia at the authors' center has not decreased over the past 20 years, but maternal mortality has been reduced from 2.1 to 0%. It was disturbing to find that management error played some role in the development of eclampsia in 50% of the cases. Significant errors--including ineffective magnesium sulfate therapy, failure to treat adequately prior to transport, and lack of communication with a perinatal center--are discussed.

Chronic hypertension in pregnancy.

Pregnancies in women with chronic hypertension are at increased risk of superimposed pre-eclampsia, abruptio placentae, fetal growth retardation and prematurity. The frequencies of these complications are increased in those women who have high-risk chronic hypertension, ie severe hypertension or pre-existing cardiovascular or renal diseases, as well as in those with target organ damage. Such women should receive antihypertensive therapy and close management to improve maternal and fetal outcome. In women with low-risk chronic hypertension, antihypertensive treatments do not improve pregnancy outcome. Prophylactic low-dose acetylsalicylic acid treatment does not reduce the frequency of superimposed pre-eclampsia nor does it improve perinatal outcome in these pregnancies.

Hypertensive disorders in twin versus singleton gestations. National Institute of Child Health and Human Development Network of Maternal-Fetal Medicine Units.

OBJECTIVE: This study was undertaken to compare rates and severity of gestational hypertension and preeclampsia, as well as perinatal outcomes when these complications develop, between women with twin gestations and those with singleton gestations. STUDY DESIGN: This was a secondary analysis of prospective data from women with twin (n = 684) and singleton (n = 2946) gestations enrolled in two separate multicenter trials of low-dose aspirin for prevention of preeclampsia. End points were rates of gestational hypertension, rates of preeclampsia, and perinatal outcomes among women with hypertensive disorders. RESULTS: Women with twin gestations had higher rates of gestational hypertension (relative risk, 2.04; 95% confidence interval, 1.60-2.59) and preeclampsia (relative risk, 2. 62; 95% confidence interval, 2.03-3.38). In addition, women with gestational hypertension during twin gestations had higher rates of preterm delivery at both <37 weeks' gestation (51.1% vs 5.9%; P <. 0001) and <35 weeks' gestation (18.2% vs 1.6%; P <.0001) and also had higher rates of small-for-gestational-age infants (14.8% vs 7. 0%; P =.04). Moreover, when outcomes associated with preeclampsia were compared, women with twin gestations had significantly higher rates of preterm delivery at <37 weeks' gestation (66.7% vs 19.6%; P <.0001), preterm delivery at <35 weeks' gestation (34.5% vs 6.3%; P <.0001), and abruptio placentae (4.7% vs 0.7%; P =.07). In contrast, among women with twin pregnancies, those who remained normotensive had more adverse neonatal outcomes than did those in whom hypertensive complications developed. CONCLUSIONS: Rates for both gestational hypertension and preeclampsia are significantly higher among women with twin gestations than among those with singleton gestations. Moreover, women with twin pregnancies and hypertensive complications have higher rates of adverse neonatal outcomes than do those with singleton pregnancies.

Bilateral renal cortical necrosis: a report of 2 cases.

Two cases of renal cortical necrosis, one of which occurred after an obstetric complication (abruptio placentae) and the other after postpartum haemorrhage, are described. The diagnosis was made by percutaneous renal biopsy, intravenous pyelography and selective nephro-angiography. Immunofluorescence studies of the kidney showed no abnormality in one patient, but showed the presence of IgM in the glomerular basement membrane in the second patient. Hypotension was not observed when anuria occurred. Both patients survived. The importance of prolonged haemodialysis is stressed, since one patient was oliguric for 57 days and required intermittent haemodialysis for 5 months, while the second patient was oliguric for 17 days, required haemodialysis for 5 months and now has established hypertension.

[Diagnosis and management of obstetric acute disseminated intravascular coagulation].

Twenty-seven in-patients with obstetric DIC in our hospital from Jan. 1971 to Dec. 1990 were analysed retrospectively. The incidence was 0.12% in the first decade and 0.02%, in the second, showing a difference of significance between them. The most common predisposing factors included amniotic fluid embolism, abruptio placenta and hemorrhagic shock. Bleeding from multi-organs in various extent and coagulation disorders occurred in all those 27 cases. [Besides anti-shock treatment, heparin was employed together with fibrinogen in 4 postpartum and 1 antepartum DIC patients, fibrinogen alone in 8 cases, and hysterectomy in 11 cases. 17 patients were saved and 9 died. It is important that early diagnosis and much attention paid to clinical characteristics together with serial laboratory tests. Key management should include prompt treatment and eradication of predisposing factors. Quick decision spite of to terminate the pregnancy and even hysterectomy should be done in some risks.

Congenital hypofibrinogenemia and recurrent placental abruption.

A 32-year-old white woman with a history of 2 episodes of abruptio placentae was found to have congenital hypofibrinogenemia. She had no bleeding difficulties except when pregnant. The patient's sisters and her mother also had reduced fibrinogen levels. Results of fibrinogen measurement by clotting assays and immunologic studies were similar. Immunoelectrophoresis, molecular weight of fibrinogen chains, cross-linking by factor XIII, carbohydrate staining, and sialic acid quantitation were all normal, suggesting the diagnosis of hypofibrinogenemia rather than dysfibrinogenemia. Fibrinolysis did not account for the reduced fibrinogen level. This case demonstrates that congenital low fibrinogen levels may be associated with placental abruption and that an abnormal fibrinogen molecule is not necessary.

Maternal morbidity and obstetric complications in triplet pregnancies and quadruplet and higher-order multiple pregnancies.

OBJECTIVE: The purpose of this study was to assess the risk of maternal morbidity and obstetric complications in women with triplet pregnancies and quadruplet and higher-order multiple pregnancies. STUDY DESIGN: We compared the outcomes in women with triplet pregnancies (n=5491) and quadruplet and higher-order multiple pregnancies (n=423) with women with twin pregnancies (n=152,238), with the use of the 1995 to 1997 Multiple Birth File of the United States. RESULTS: After an adjustment was made for important confounding factors, the risks of pregnancy-associated hypertension and eclampsia, anemia, diabetes mellitus, abruptio placenta, premature rupture of membrane, and cesarean delivery were increased in women with triplet pregnancies and quadruplet and higher-order multiple gestations than in women with twin pregnancies. A dose-response relationship was observed for pregnancy-associated hypertension, diabetes mellitus, and placental abruption, with higher odds ratios in women with quadruplet and higher-order multiple gestations than in women with triplet pregnancies. CONCLUSION: The risks of maternal morbidity and obstetric complications are increased in triplet pregnancies and quadruplet and higher-order multiple pregnancies than in twin pregnancies; for certain outcomes, there is a dose-response relationship.

Outcome of pregnancies with preterm premature rupture of membranes.

OBJECTIVE: To study the outcomes of pregnancies complicated with preterm premature rupture of the membranes (PPROM) between 26-36 week gestation. METHODS: A retrospective study of 36670 pregnancies registered and managed in the Department of Obstetrics and Gynecology, King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia (KSA) from March 1993 to February 2003. RESULTS: Two hundred and twenty cases of PPROM (0.6%) were registered and treated expectantly out of 36670 total pregnancies registered during the study period. The majority of the cases (38.6%) were delivered within 72 hours of premature rupture of the membranes (PROM). Only 2.3% of the cases were prolonged to a latency period of more than one month. Maternal morbidity included chorioamnionitis (20.9%), postpartum endometritis (6.8%), abruptio placentae (4%) and septicemia (0.5%). The prenatal survival rate was 94.5% whereas neonatal outcomes included neonatal mortality (5.5%), respiratory distress (15.9%), sepsis (7.7%), and necrotizing enterocolitis (3.1%). Our study showed a positive correlation between increasing maternal age and cesarean section; increased maternal and neonatal infection rates with prolonged latency; and increased risk of neonatal infection among mothers having chorioamnionitis. CONCLUSION: The incidence of PPROM in KSA is low. Ultimate goal of therapy must be safety of the mother first. Expectant management should be the rationale if fetal immaturity exists. Induction of labor in PPROM patient > or = 34-week-gestation is a logical approach to minimize maternal infectious morbidity.

Acute renal failure in preeclampsia-eclampsia.

Acute renal failure (ARF) is regarded as relatively uncommon in preeclampsia-eclampsia (PE-E) and, in any event, of moderate degree or reversible. Cortical necrosis is reported as rare, even in fatal cases. Little light has as yet been shed on the mechanisms responsible for ARF in PE-E. This paper describes 17 cases observed over the last 15 years, in which cortical necrosis (3 histological and 2 clinical diagnoses) was relatively frequent (29.4%). The severity of renal impairment did not appear to be related to chronological age, parity, period of pregnancy in which PE-E commenced and its duration prior to delivery, presence of frank eclamptic crises or the concomitance of earlier vascular or renal disease (p greater than 0.05). The superimposition of abruptio placentae (AP) was the only clinical factor significantly correlated with cortical necrosis (p greater than 0.05). The association PE-E + AP seems to be a particularly unfavorable prognostic sign for the kidney owing to the contribution of additional damage mechanisms (vasospasm, disseminated intravascular coagulation, hemorrhagic shock) furnished by AP, while PE-E itself prepares the ground for AP. The fact that PE-E is difficult to diagnose when AP is the onset symptom may be responsible for the underestimation of its contribution towards the induction of severe renal damage.

Eclampsia. III. Neonatal outcome, growth, and development.

Infants of 72 recently managed women with eclampsia before delivery were studied. Infants with gestational age of 36 weeks or less (56%) were analyzed separately from those infants of more than 36 weeks' gestation (44%). In addition, premature infants of eclamptic mothers were compared with 40 premature infants whose mothers did not have any medical complications. Intrauterine growth retardation was symmetrical in all seven infants whose mothers had eclampsia prior to 32 weeks. All neurological abnormalities were associated with abruptio placentae or intrauterine growth retardation. Among the preterm infants of eclamptic mothers and those of normotensive mothers, there was no significant difference in any commonly acquired laboratory data. Neonatal complications in premature infants of eclamptic mothers were frequent. However, neonatal complications of the low-birth weight infants were strikingly similar regardless of the presence of eclampsia. It is possible that most neonatal complications are consequence of prematurity, instead of a sole consequence of eclampsia. Observations from follow-up data (up to 4 years of age) suggest normal growth and development for infants of mothers with uncomplicated eclampsia.

[Alcohol consumption among pregnant women and outcome of pregnancy (author's transl)].

A prospective survey of more than 9,000 pregnant women showed that those who consumed more than 0.4 l of wine or equivalent in other alcoholic beverages per day during pregnancy had a higher risk of unfavourable outcome. The risk of stillbirth was higher, particularly that due to abruptio placentae. The average birthweight was lower and the risk of giving birth to a small-for-date infant was higher. Furthermore the men placental weight was lower. Women with moderate or high alcohol consumption also differed from those with low alcohol consumption in some classical risk factors for the outcome of pregnancy, but the increased risk with consumption of alcohol remained significant when these other factors were taken into account. The increased risk among women with moderate or high alcohol consumption appeared to be limited to beer drinkers, although the mean quantity of alcohol consumed by beer drinkers was smaller than that consumed by wine drinkers.

Accuracy of reporting maternal in-hospital diagnoses and intrapartum procedures in Washington State linked birth records.

While the impact of maternal morbidities and intrapartum procedures is a common topic in perinatal outcomes research, the accuracy of the reporting of these variables in the large administrative databases (birth certificates, hospital discharges) often utilised for such research is largely unknown. We conducted this study to compare maternal diagnoses and procedures listed on birth certificates, hospital discharge data, and birth certificate and hospital discharge data combined, with those documented in a stratified random sample of hospital medical records of 4541 women delivering liveborn infants in Washington State in 2000. We found that birth certificate and hospital discharge data combined had substantially higher true positive fractions (TPF, proportion of women with a positive medical record assessment who were positive using the administrative databases) than did birth certificate data alone for labour induction (86% vs. 52%), cephalopelvic disproportion (83% vs. 35%), abruptio placentae (85% vs. 68%), and forceps-assisted delivery (89% vs. 55%). For procedures available only in hospital discharge data, TPFs were generally high: episiotomy (85%) and third and fourth degree vaginal lacerations (91%). Except for repeat caesarean section without labour (TPF, 81%), delivery procedures available only in birth certificate data had low TPFs, including augmentation (34%), repeat caesarean section with labour (61%), and vaginal birth after caesarean section (62%). Our data suggest that researchers conducting perinatal epidemiological studies should not rely solely on birth certificate data to detect maternal diagnoses and intrapartum procedures accurately.
