Teenage pregnancy: risk factors for adverse perinatal outcome.

OBJECTIVES: To assess the perinatal outcome of teenage pregnancy in a large cohort and to determine risk factors for low birth weight (LBW) in teenage pregnancy. STUDY DESIGN: All singleton first deliveries to mothers of age 16-24 years between 1990 and 1997 were included. The deliveries were subdivided into three maternal age groups (16-17 and 18-19 compared to 20-24 years) and parameters of perinatal outcomes were compared. To adjust for potential confounding effects on the association between young maternal age and birth weight, logistic regression analysis was performed for LBW with maternal ethnicity, pregnancy-induced hypertension, lack of prenatal care and malformations of the newborn. RESULTS: Among a total of 11 496 patients, 600 (5.2%) were 16-17 years old, 2097 (18.2%) were 18-19 years old and the remaining 8799 (76.6%) were 20-24 years old. Bedouin ethnicity and lack of prenatal care were common in the youngest mothers. Rates of preterm delivery were 14.2%, 9.8% and 8.8% in the three age groups, respectively (p < 0.05). Rates of malformations, small for gestational age, LBW and very LBW were also significantly higher in the youngest mothers. Rates of pregnancy-induced hypertension, operative delivery and Cesarean delivery were not significantly different among the three age groups. A multivariate analysis on LBW was performed to assess the unique contribution of young maternal age, adjusted for potential confounders. Adjusted ORs for LBW were 1.25 (95% CI 1.00-1.56) for maternal age < 18 years, 1.80 (95% CI 1.54-2.03) for Bedouin ethnicity, 2.57 (95% CI 2.14-3.07) for pregnancy-induced hypertension, 1.55 (95% CI 1.30-1.84) for lack of prenatal care and 4.09 (95% CI 3.2-5.2) for malformations. CONCLUSIONS: Teenage pregnancy was found to be associated with adverse outcome such as LBW, preterm delivery, small for gestational age and malformations. The risk for LBW was affected mainly by demographic factors (maternal ethnicity, lack of prenatal care) and medical factors (pregnancy-induced hypertension, malformations).

A comparison between the effectiveness of epidural analgesia and parenteral pethidine during labor.

The study was aimed to define parturients' opinion on either epidural analgesia or intravenous pethidine, and to determine the effect of both analgesics after delivery. We interviewed and examined 401 consecutive parturients who requested analgesia during the beginning of their active stage of labor. Of those, 131 women requested and underwent epidural analgesia, and 270 received parenteral pethidine. The pain experienced before admission of any analgesia, was significantly higher in the epidural group than in the parental group (mean visual analog scale (VAS) score 8.9 and 8.4, respectively; P=0.004). However, after analgesics, women from the epidural analgesia experienced significantly less pain during labor as compared to those receiving pethidine (mean VAS scores 5.05 vs. 9.14, respectively; p<0.001). The pain scores 24 h after labor were significantly lower in patients who underwent epidural analgesia (1.69 vs. 2.13, respectively; p<0.001). We conclude that epidural analgesia is more effective than parenteral analgesia in pain and discomfort relief. This method is helpful also the day after delivery. Thus, epidural analgesia should be strongly recommended to all patients who do not have any medical contraindications to this method of treatment.

Predictors of recommendation and acceptance of intrapartum epidural analgesia.

UNLABELLED: We conducted this prospective study to characterize the obstetric and sociodemographic variables that predict physicians' recommendations and patients' acceptance of intrapartum epidural analgesia. The study population consisted of 447 consecutive, low-risk parturients in early active labor. Epidural analgesia was recommended to 393 patients (87.9%), however only 164 (41.7%) consented to receive it. A multiple logistic regression analysis demonstrated that the severity of pain, as assessed by the medical staff (odds ratio [OR] = 1.5, 95% confidence interval [CI] 1.13, 1.93), low parity (OR = 0.57, 95% CI 0.44, 0.74), and low maternal age (OR = 0.89, 95% CI 0.79, 0.99) were significant factors affecting recommendations of epidural analgesia. In a multivariate analysis, severity of subjective pain (OR = 1.39, 95% CI 1.16, 1.68), low parity (OR = 0.80, 95% CI 0.73, 0.99), high education (OR = 90.09, 95% CI 27.02,257.06), and the patients' being secular compared with religious (OR = 2.14, 95% CI 1.08,4.21) were found to be independent predictors of acceptance of epidural analgesia. There are differences between patients offered and those not offered epidural analgesia and between parturients who accept and those who do not accept this analgesia. IMPLICATIONS: We studied the factors that influence the recommendation of epidural analgesia by obstetricians, as well as its acceptance by the laboring patients at a university hospital in Israel. Epidural analgesia was recommended more often to low parity, younger women exhibiting more pain. Parturients who perceived greater pain were more secular, had low parity, and had a higher level of education were more likely to accept it.

Dual distant uterine placental insertion connected by a placental band. A case report.

BACKGROUND: There are several types of intrauterine membranes; most are not associated with any deleterious effect on fetal outcome. CASE: An unusual placental insertion was diagnosed sonographically at 23 weeks of gestation. It consisted of two distant placental insertions into the uterine wall, with a large placental mass between them floating freely in the uterine cavity. Normal fetal growth pattern and blood flow indices were found. A normal female neonate was delivered via low transverse cesarean section. There were no macroscopic or microscopic placental anomalies. CONCLUSION: This case raises several questions: the right mode of delivery, frequency of ultrasound follow-up and possibility of placental band rupture and hemorrhage during vaginal delivery.

Outcome of ovum donation in Turner's syndrome patients.

OBJECTIVE: To determine whether there is a difference in the pregnancy rate in women with Turner's syndrome (45,X) in an ovum donation program compared with women with other causes of premature ovarian failure. DESIGN: Retrospective chart review of women with Turner's syndrome (n = 11) and premature ovarian failure (n = 38) in a donor ovum program using variable dose and duration of E2 replacement therapy for endometrial preparation and using only transvaginal ultrasonographic assessment of endometrial response before ET. RESULTS: The pregnancy rates in Turner's syndrome patients and control subjects were 27% and 25%, respectively. Pregnancy rates were higher in the first cycle than in subsequent cycles for both groups (40% versus 8%). CONCLUSIONS: Turner's syndrome patients given a variable dose of estrogen, for endometrial preparation, with response assessed exclusively by transvaginal ultrasonography demonstrated pregnancy rates equal to patients with other causes of premature ovarian failure.

Culdocentesis is an obsolete diagnostic tool in suspected ectopic pregnancy.

We studied 332 patients with proven pregnancies. Prediction of hemoperitoneum by assessment of the Douglas pouch during bimanual examination had a false negative rate of 42.1%. The false negative rate for culdocentesis was 14.8%. It is therefore concluded that culdocentesis is not a useful tool in the diagnosis of suspected ectopic pregnancies.

Rethinking science policy.

Industry is now investing heavily and at an increasing rate in research and development. The government's responsibility should be to assure that this industrial spending is paralleled by real growth in its support of basic research. Such growth is realistic, even in times of budgetary constraints, given a proposed compact between the scientific community and the government, in which, inter alia, a small percentage of the funds spent on development would be reprogrammed for basic research.

How thick is the lithosphere?

A rapid decrease in shear velocity in the suboceanic mantle is used to infer the thickness of the lithosphere. It is proposed that new and highly precise group velocity data constrain the solutions and imply a thickness near 70 km.

Obstetric performance in Ethiopian immigrants compared with Israeli parturients.

It was the aim of this study to evaluate the obstetric performance of Ethiopian Jewish immigrants in comparison to the general Jewish obstetric population. The study was performed at the Soroka Medical Center, Beer Sheva, which manages the busiest delivery ward in Israel. Between 1988 and 1991 a total of 20,047 non-Ethiopian women (Group N) and 431 parturients of Ethiopian origin (group E) delivered at the Soroka Medical Center. Group E included a significantly higher percentage of grandmultiparous women than group N. Among diseases complicating pregnancy there was a statistically significant higher incidence of severe pregnancy-induced hypertension (PIH) in group E than in group N. Mild PIH and chronic hypertension were of comparable prevalence in both groups. The prevalence of class A diabetes mellitus was significantly lower in group E than in group N; the same trend was also observed for diabetes class B but without reaching statistical significance. There was no significant difference between the groups in the prevalence of polyhydramnios, postdatism and poor obstetric history, or fetal distress, s/p cesarean section, and prolapse of cord. Statistical analysis indicated a tendency towards significance for higher prevalence of premature rupture of membranes in group N. Malpresentations and malpositions were of similar prevalence in both groups. The incidence of premature delivery in group E showed a higher relative risk, suggesting a tendency of significance. The incidence of meconium-stained amniotic fluid in group E was significantly higher than in group N. There was no significant difference in the prevalence rates of placental complications such as placenta previa and abruption of placenta between the groups. The mode of delivery, the prevalence of complications during the third stage of labor, birthweight of infants and perinatal mortality were similar for both groups. In conclusion, the obstetric performance in Ethiopian Jewish immigrants is surprisingly similar to that of Israeli Jewish parturients. The only prominent pathology that does not seem to be related to life-style and nutrition is pregnancy-induced hypertension.
