[Current profile of obstetrical vesicovaginal fistulas at the maternity unit of the University of Casablanca].

Obstetrical vesicovaginal fistulas are secondary to dystocia. Late and inappropriate treatment are still a health public problem in under development countries. In five years (1993-1997), twelve vesicovaginal fistulas were repertored in the department of obstetrics and gynaecology of Casablanca (Morocco) with a frequency of 0.33@1000 deliveries and 2.4 new cases a year. 80% of the cases occurred after a long labour without efficient obstetrical care. Most of the cases (75%) were simple with an easy surgical treatment. All the fistulas were resolved after one or two surgical procedures realised by vaginal route in eight cases (2/3). During these last decades, with the efforts in obstetrical care in our country, we are assisting in a diminution of the frequency of this pathology and specially the number of complicated fistulas.

Marfan syndrome in the parturient.

Early recognition of the Marfan Syndrome and knowledge of its potentially lethal complications facilitates successful treatment of these individuals. It is through a joint effort by many specialist physicians such as the obstetrician, cardiologist, and anesthesiologist that these patients can be managed safely through pregnancy, labor, and delivery.

Reasons for the rising cesarean delivery rates: 1978-1984.

This study was undertaken to estimate the cesarean delivery rate in United States hospitals and to determine whether the reasons for rise in this rate have changed since the National Institute of Child Health and Human Development Consensus Development Conference on Cesarean Childbirth in 1979. The cesarean delivery rate steadily increased from 9.1% in 1974 to 14.7% in 1978, and to 21.2% in 1984. One-third of the rise in the cesarean rate from 1974-1978 was due to repeat cesareans, and 9% was due to fetal distress. Since 1978, 47% of the rise in the cesarean rate was attributed to repeat cesareans, and 16% to fetal distress. Less of the recent rise in the cesarean rate was due to dystocia and breech presentation. The rate of cesarean delivery among those with a previous cesarean was 96%. Deliveries complicated by fetal distress increased from 1% in 1978 to 6% in 1984. The incidence of breech presentation dropped by 18% (2.8-2.3%), which may indicate an increase in the successful use of external cephalic version. If the number of vaginal deliveries after cesarean increases in the future, then the overall cesarean delivery rate will decrease or stabilize. Additional efforts should be focused on the diagnostic categories of fetal distress and dystocia, because it is likely that the definitions of these complications are changing to include less severe forms.

Maternal and infant complications in high and normal weight infants by method of delivery.

OBJECTIVE: To estimate the population risks of maternal and infant complications with the birth of macrosomic (at least 4000 g) compared with normal weight infants. METHODS: Term, singleton infants were identified from the state of Washington's birth event records database for 1990. Diagnosis codes from the Internal Classification of Diseases (9th revision) were used to identify delivery method and previously defined complications. We adjusted for maternal demographic and clinical factors using multivariable logistic regression to derive the risk of each maternal and infant complication. RESULTS: The incidence of macrosomia was 13% (8815 of 66,086). Vaginal birth of macrosomic infants was associated with low incidence of complications except for shoulder dystocia (11%) and postpartum hemorrhage (5%). Postpartum infection was the most common complication for women who had cesarean delivery after labor (5%), and complications for women who had cesarean without labor were rare (less than 3%). Neonatal complications were rare. Among infants with shoulder dystocia, the risks of asphyxia (adjusted relative risk [RR] 1.2, 95% confidence interval [CI] 0.6, 2.3), birth trauma (RR 0.6, 95% CI 0.2, 1.6), long-bone injury (RR 1.2, 95% CI 0.6, 2.4), seizures (RR 1.0, 95% CI 0.0, 25.0), and facial palsy (RR 2.2, 95% CI 0.2, 44.4) were not significantly different for macrosomic and normal weight infants; however, macrosomic infants had a significantly increased risk of Erb palsy (RR 3.5, 95% CI 1.8, 7.5). CONCLUSION: This population-based study showed that most macrosomic infants are delivered vaginally with low rates of maternal and neonatal complications. Macrosomic infants have higher rates of Erb palsy, but similar rates of other serious complications of shoulder dystocia when compared with normal weight infants.

[Predictive factors of the delivery method in women with cesarean section scars].

OBJECTIVE: To determine the independent effect of clinical and non clinical factors on the mode of delivery after previous cesarean section. METHODS: We performed a retrospective multicenter study of 579 women who had previously undergone a cesarean section and who delivered between January 1995 and June 1997. Maternal and perinatal morbidity associated with trial of labor and elective repeat cesarean was assessed. Multiple logistic regression was used to identify prognostic factors for the outcome of a trial of labor. The odds ratios provided indicate the risk of cesarean section when the factor is present. RESULTS: The rate of successful trial of labor was 74.5%. Overall morbidity was not increased in the trial of labor group. The variables of significant predictive value were the Bishop's score (OR = 15.2 for a score < 3; 95% CI: 5.54 to 41.9), an anomaly of the pelvis (OR = 5.89; 95% CI: 2.37 to 14.7), a previous vaginal delivery (OR = 0.27; 95% CI: 0.12 to 0.60), a fetal distress (OR = 4.11; 95% CI: 2.01 to 8.43), the weight gain during pregnancy (OR = 2.01; 95% CI: 1.10 to 3.68), a delivery between 11 p.m. and 7 a.m. (OR = 0.29; 95% CI: 0.13 to 0.66), a hypertension (OR = 3.10; 95% CI: 1.09 to 8.80) and the use of an intra-uterine pressure catheter (OR = 0.26; 95% CI: 0.11 to 0.57). CONCLUSION: A trial of labor should be allowed in most of the women with previous cesarean section. The Bishop's score is the best predictor of the mode of delivery. Induction of labor and a first cesarean for dystocia do not affect the chances of vaginal birth.

The effect of nuchal cord on amniotic fluid and cord blood erythropoietin at delivery.

OBJECTIVE: We investigated the effect of a nuchal cord on fetal hypoxia by using amniotic fluid and cord blood erythropoietin as markers of chronic and acute hypoxia, respectively. METHODS: A total of 167 full-term pregnancies without maternal complications or fetal prelabor complications except fetal growth restriction of unknown cause were studied prospectively. Of these, 47 had a nuchal cord at delivery, and 62 had one or more complications during labor and delivery (nonreassuring fetal heart rate pattern, birth weight less than 2500 g, Apgar score at 1 minute less than 7, presence of meconium-stained amniotic fluid, oligohydramnios), and 26 had both nuchal cord and at least one of the intrapartum complications. RESULTS: Erythropoietin levels (mean +/- standard error of the mean) were not significantly different between the nuchal cord group (n = 47) and the no nuchal cord group (n = 120) in either amniotic fluid (19.3 +/- 4.1 mU/mL versus 13.7 +/- 1.1 mU/mL) or cord blood (57.9 +/- 10.3 mU/mL versus 52.1 +/- 4.9 mU/mL). Similarly, in the 62 fetuses with intrapartum complications, there were no significant differences in amniotic fluid (14.3 +/- 2.0 mU/mL versus 18.8 +/- 2.9 mU/mL) or cord blood erythropoietin (66.9 +/- 16.8 mU/mL versus 72.6 +/- 12.6 mU/mL) levels between those with (n = 26) or without a nuchal cord (n = 36). Among the 107 uncomplicated cases, however, amniotic fluid erythropoietin was significantly elevated in the nuchal cord group (25.5 +/- 8.7 mU/mL, n = 21) compared with that in the no nuchal cord group (11.5 +/- 0.9 mU/mL, n = 84) (P <.05), whereas there was no significant between-group difference in cord blood erythropoietin levels between nuchal cord and no nuchal cord groups (46.8 +/- 10.0 mU/mL versus 43.3 +/- 4.1 mU/mL). Tightness of the nuchal cord did not affect amniotic fluid or cord blood erythropoietin concentrations. CONCLUSION: Although nuchal cord may not significantly increase the risk of acute or labor-associated fetal hypoxia, it appears to be an independent risk factor of mild, chronic, prelabor fetal hypoxia.

Ruptured ovarian artery aneurysm complicating a term vaginal delivery.

Ruptured ovarian artery aneurysm is rare. Of the eight cases previously reported, seven were diagnosed postpartum. Our case of a ruptured right ovarian artery aneurysm was associated with massive retroperitoneal bleeding. The probable time of rupture could be traced to the second stage of labor. This case indicates the need for early evaluation of atypical flank pain during labor.

Pregnancy, delivery, and neonatal complications among autistic children.

An investigation of the prenatal, delivery, and neonatal experience of 145 autistic children matched with 330 unaffected siblings revealed that among the propositi there was a preponderance of first-born children. Obstetrical records, which had been made prior to the diagnosis of autism, indicated that autistic children were more likely than their siblings to have experienced at least one untoward event during their mothers' gestations and deliveries. Similarly, the autistic children had an increased risk of neonatal complications. Despite the significant excess of total reproductive complications in the autistic series, there was no single event or a combination of biologically related complications that could reasonably account for any large number of cases of autism. While it is possible that autism may be the product of several diverse deleterious events experienced in utero, during delivery, or in the early neonatal period, our finding could be a chance occurrence or could signal the presence of a unknown factor responsible both for autism and for a variety of reproductive complications.

Skeletal tuberculosis, pelvic contraction, and parturition.

Obliquely contracted pelvis was observed in association with tuberculosis and dystocia (difficult parturition) in four out of 762 childbearing women in a Southeast Asian population. It is hypothesized that the pelvic contracture results from tuberculosis of the sacro-iliac joint with destruction of the sacral ala. This gross morphologic deformity, as observed in living populations, may be a useful marker for skeletal tuberculosis in prehistoric and historic populations as well. The occurrence of obliquely contracted pelvis with consequent dystocia as a specific complication of systemic tuberculosis may have direct implications for differential reproductivity.

Predisposing and risk factors of umbilical cord prolapse.

Altogether 117 deliveries (0.14%) out of 82 308 were complicated by umbilical cord prolapse (UCP) in the obstetrical department of Tampere University Central Hospital in the period 1962-81. The gross perinatal mortality rate in the present study was 16.2%, but during the last 5-year period the incidence of UCP (0.09%) as well as the perinatal mortality rate (5.9%) declined significantly. UCP seemed to be more prevalent during the first half of the year. The most prominent precipitating factors for the occurrence of UCP seemed to be abnormal presentation, multiple pregnancy, low birth weight, and multiparity. Amniotomy seemed not to increase the risk for UCP. Diminished perinatal mortality figures were closely associated with increased cesarean section rates in the management of deliveries complicated by UCP. Cesarean section is therefore recommended as the treatment of choice for deliveries complicated by UCP.
