OBJECTIVE: Earlier works have associated neonatal clavicular fracture (0.2-3.5% of all deliveries) with a range of procedural, fetal and maternal risk factors; more recent studies, however, have failed to firmly identify any one or a combination of them. In the present work we sought to determine possible ante/intra-partum risk factors ...

OBJECTIVE: Corticotropin releasing hormone, a hypothalamic neuropeptide, plays a major role in regulating pituitary-adrenal function and the physiologic response to stress. During pregnancy corticotropin-releasing hormone is synthesized in large amounts by the placenta and released into the maternal and fetal circulations. Various endocrine, autocrine, and paracrine roles have been suggested ...

The purpose of this paper is to review the issue of fetal rights from primarily a legal perspective, with consideration of morals and professional ethics. The practice of medicine is fraught with numerous bioethical dilemmas. These dilemmas often leave the physician wondering if he has made the correct decision. A ...

Maternal thyrotoxicosis complicates approximately 0.2% of pregnancies. Simultaneous occurrence of maternal and fetal thyrotoxicosis during labor is rare, and control of maternal tachycardia and hypertension, as well as fetal manifestations of thyrotoxicosis, are cornerstones of management. An 18-year-old nulliparous female at 33 weeks gestational age presented in labor with thyrotoxicosis. ...

OBJECTIVE: We investigated the usefulness of cervicovaginal interleukin-1beta and interleukin-8 levels during pregnancy as markers of preterm and term parturition. STUDY DESIGN: Cervicovaginal fluids were obtained from 119 pregnant women at 24 to 41 weeks' gestation. Cytokine concentrations were measured by enzyme-linked immunoassay. RESULTS: Interleukin-1beta and interleukin-8 concentrations in cervicovaginal ...

The amount of stress experienced by both the mother and fetus during labor and delivery varies considerably and is likely to be different in primiparous and multiparous women. In this study we explored relations between the birth experience and lactation performance of 40 women. Stress hormones were measured in serum ...

Hypertrophic cardiomyopathy (HCM) in pregnancy can result in a high incidence of maternal complications. Although echocardiography is frequently performed in pregnant women with HCM in order to confirm their hemodynamic classification, this modality has not been applied during labor and delivery in these patients. This case report documents the application ...
Mijovic J E - - 1998
Term and preterm parturition is associated with elevated intrauterine PG production. Although an increase of PG synthesis by the fetal membranes during term labor is well documented, there is little data available regarding the prostanoid production of these tissues at term, before the spontaneous onset of labor. In the present ...

OBJECTIVE: The purpose of this study was to determine whether magnesium sulfate given for prevention of eclampsia affected labor outcomes compared with phenytoin, which is not known to impede uterine activity when given in anticonvulsant doses. STUDY DESIGN: Secondary analysis was performed of a study of women with pregnancy-induced hypertension ...
Hon E H - - 1998
This report describes hemodynamic patterns recorded from patients who had spontaneous abortion, preterm, and term labor. A working hypothesis theorizes that specific patterns observed in these situations can be identified and correlated with those present in the preovulatory and postovulatory phases of the menstrual cycle and thereby provide a clue ...

Both mother and fetus have the remarkable ability to adapt to conditions of chronic hypoxia during the course of gestation. One of these adaptations appears to be mechanisms that prevent premature delivery despite the chronic stress of hypoxia. Our studies in the chronically hypoxic sheep revealed that the fetal adrenal ...
Murphy K - - 1998
OBJECTIVE: We assessed the relation of fetal station in early labor to subsequent patterns of dilation and descent and to the probability of cesarean delivery. STUDY DESIGN: We evaluated 132 nulliparous women who were in spontaneous latent-phase labor with singleton, vertex-presenting, term fetuses. For each participant, pertinent variables relating to ...

Fetal oxygen saturation (FSpO2) was monitored with the Nellcor Puritan Bennett N400/FS14 system during 16 labors to establish whether FSpO2 was influenced by maternal bearing down efforts in the second stage of labor. Fetal SpO2 is reported for 16 fetuses where neonatal outcome was normal. One hour of continuous data ...

To evaluate changes in vaginal polymorphonuclear leukocytes (vPMNL) in patients with preterm labor, we obtained vPMNL-rich suspensions from vaginal fluids of 77 women (21 with preterm labor and 56 control women with uncomplicated pregnancy). Total counts of vPMNL and % viability of vPMNL (viable vPMNL:total vPMNL) were significantly higher in ...

There is substantial evidence that there is an increased incidence of cesarean delivery among patients who receive epidural analgesia during labor. The controversy as to whether there is a causal relationship between epidural analgesia and cesarean delivery. Two prospective, randomized studies suggest that epidural analgesia may increase the incidence of ...

Mathews T J - - 1997
Between 1989 and 1995 the rates for stimulation and induction of labor rose every year, representing a 48 and 77 percent, respectively, total rise over the time period. In 1995 the rate of stimulation was 161 per 1,000 live births and of induction 160. Two percent, or 74,167, of the ...
Matsumoto T - - 1997
Prostaglandin (PG) E2 and PGF2 alpha are believed to play important roles in the myometrial contraction and the initiation of labor. Myometrial contraction by these prostanoids is mediated mainly through EP3 and FP, which are specific receptors to PGE2 and PGF2 alpha, respectively. During normal pregnancy, uterine myometrium are relaxed ...
Rayburn W F - - 1997
Obstetricians frequently prescribe drugs for indications other than those on the product label. Reasons for such off-label use during pregnancy include prevention of repetitive abortion, inhibition of premature labor, reduction of fetal or neonatal infection, reduction in development of preeclampsia and its complications, and ripening of the cervix or induction ...
Greig P C - - 1997
OBJECTIVE: To determine the normal concentrations of maternal serum interleukin-6 during the second and third trimesters of pregnancy and the different stages of term and preterm labor, and to examine the clinical usefulness of measuring this cytokine in the serum of women in preterm labor to diagnose asymptomatic intrauterine infections. ...

Of these, 35 (11%) received epidural ...
Schellenberg J C - - 1997
Prostaglandin production in amnion and decidua is considered important for human parturition. We investigated in pregnant guinea pigs, a species similar to women in regard to the endocrinology of pregnancy, whether the production rates of PGE2 and PGF2 alpha in various intrauterine tissues are compatible with a role in parturition. ...
