Segawa's syndrome is a hereditary progressive dystonia with diurnal fluctuation, which in contrast to other chronic dystonia in childhood responds dramatically to levodopa therapy. Very little is known on how it affects pregnancy or how it is affected by the pregnancy. We present a case of pregnancy of a patient, ...

Optimal interpretation of the events of labor requires integration of information about cervical changes, fetal descent, uterine contractions, fetal position and attitude, as well as fetal heart rate monitoring and maternal condition. The use and understanding of labor curves is a vital part of this process. The complexity and diversity ...

The use of prostaglandins in obstetrics has undergone a rapid evolution since their discovery in the early 1970s. It appears certain now that, at least in some cases, prostaglandins are important mediators of uterine activity. Indeed, a much stronger case can be made for the role of prostaglandins in labor ...

Meralgia paresthetica is a common sensory mononeuropathy of the lateral femoral cutaneous nerve which occurs in pregnancy as well as in many other conditions. The most likely etiology in pregnancy is entrapment of the nerve as it passes around the anterior superior iliac spine or through the inguinal ligament. Onset ...

"The notion of the United States as ¿the mother of exiles' is an illusion, a legend perpetuated during an era when cheap immigrant labor was necessary to fuel the development of the country. The truth is that immigrants have been shunned for much of our history, tolerated only because their ...

We evaluated the possible benefits of antepartum surveillance during the 41st week of pregnancy in a low-risk population. Three hundred low-risk patients (study group) underwent a nonstress test (NST) at the beginning of the 41st week of pregnancy. Outcomes in study group patients who delivered during the 41st week were ...

Parturition is a process that is composed of five separate and distinct physiological components but which lead from one to the next and are, therefore, interdependent. As such, the regulation of myometrial contractility should not be examined in isolation but as part of this continuum. The initiation of labor begins ...

We observed the influence of commonly used oxytocin infusion for inducing labor on the fetal heart rate (FHR). The FHR was analyzed on-line by Sonicaid Computer System 8000. There were no statistical changes in all analyzed parameters during infusion of oxytocin. Our study shows that the standard dosage of oxytocin ...
Gonser M - - 1995
Traditional protocols for oxytocin infusion regimens recommend increases of infusion rate at 15-20 min intervals. However recent clinical studies agree that prolonged intervals of 30-40 or even 60 minutes are superior to shorter dosage intervals in terms of safety and efficacy. These results are in good agreement with recent pharmacologic ...

Persistent occipito-posterior position (POP) is found in about 1% of labors, and its management is still controversial. A study group of 319 patients with POP deliveries were screened and analyzed for prepartum, intrapartum and postpartum parameters. A control group of the same size was matched for maternal age (mean 27-28 ...
Kaplan B - - 1995
The aim of this study was to evaluate whether prolonged pregnancy was associated with dangers to the fetus, and to assess the incidence of cesarean section as well as fetal distress. The outcome for mother and baby in both groups of patients with post-term pregnancies was generally good. Furthermore, the ...
Schellenberg J C - - 1995
The mechanism of the onset of labor is unknown in humans and guinea pigs. Contrary to most other species, progesterone withdrawal appears not to precede the onset of labor. To elucidate the role of oxytocin in the onset and maintenance of labor, guinea pigs were fitted with vascular catheters, an ...

Fetal macrosomia is a known intrapartum risk factor for fetal injury and maternal morbidity. The purpose of this study was to review our experience with macrosomic fetuses in nondiabetic pregnancies and compare perinatal outcomes between those whose labor had been spontaneous or induced. Between January 1989 and December 1991, the ...

beta-endorphin (beta-EP) levels increase in maternal plasma starting from the 10th to the 12th week of pregnancy and reach a peak during labor and at delivery. Respiratory autogenous training (RAT) has been acclaimed as one of the most effective non-pharmacological methods of obtaining hypoalgesia and relaxing perineal muscles during labor. ...

OBJECTIVE: To evaluate the use of intrapartum intrathecal narcotic analgesia in the obstetric population of our community-based hospital. METHODS: A protocol to administer intrapartum intrathecal narcotic analgesia was established at our institution in December 1992. All patients consenting to this procedure received a single lumbar intrathecal injection of 25 micrograms ...

The effect of prostaglandin E2 on fetal urine production was examined in women undergoing labor induction. An effect may be expected, because the administration of indomethacin, a potent antiprostaglandin, has been shown to cause a decrease in fetal urine production and subsequent oligohydramnios. The mean hourly fetal urine production before ...

Leukocyte counts and lymphocyte subpopulations were measured in umbilical cord blood obtained from normal pregnancies delivered either vaginally or by elective cesarean section. In the group delivered vaginally there were significantly higher median values for neutrophils, monocytes, and natural killer cells. The leukocytosis associated with labor is selective for mediators ...
Sawai S K - - 1994
OBJECTIVE: To shorten post-date pregnancies in a safe, effective manner by outpatient acceleration of cervical ripening. METHODS: Eighty patients with uncomplicated pregnancies at or beyond 41 weeks' gestation and a cervical Bishop score less than 9 were randomized to daily self-administered, 2-mg intravaginal prostaglandin E2 (PGE2) or placebo suppositories. Each ...
Boozarjomehri F - - 1994
OBJECTIVE: Our purpose was to test the hypothesis that transvaginal ultrasonographically determined characteristics of the cervix are associated with duration of induced labor. STUDY DESIGN: Fifty-three patients scheduled for induction of labor underwent transvaginal ultrasonography and digital cervical examinations before labor induction.

The production of prostaglandins from amnion, chorion, decidua, and myometrium was studied in a superfusion system to determine the level of prostaglandin production during late pregnancy, during spontaneous labor, and after in vivo treatment with RU486. Tissues were divided into three groups: those from pregnant control animals, those from animals ...
Rodriguez A I - - 1994
OBJECTIVE: Both blunt and sharp expansion of the initial incision at transverse cervical cesarean birth have advocates, on the basis of theoretic concerns. We sought to study the incidence of complications, including unintended extension, associated with each of these methods by comparison by means of a prospective, randomized study. STUDY ...

OBJECTIVE: To measure the apparent volume of distribution (AVOD) for magnesium (Mg) in preeclampsia and preterm labor and determine if a standard 4 gm loading dose of magnesium sulfate (MgSO4) is sufficient to attain therapeutic levels. METHODS: Twenty-five patients with preeclampsia and 25 with preterm labor received 4 g of ...
Nathanielsz P W - - 1994
Recent studies on the capabilities of the fetus in the last third of gestation demonstrated that the fetus actively prepares for its journey to the extrauterine environment. The most remarkable of these preparations is that the fetal brain gives the signal to begin the birth process. Several studies, particularly those ...
Rojansky N - - 1994
BACKGROUND: To investigate whether sonographic examination of the fetal head extension, pelvic adequacy and fetal position, could replace the traditional x-ray method in the evaluation of the breech in labor. METHODS: Seventy-two parturients admitted in labor with a breech presentation were prospectively evaluated by a newly proposed ultrasonographic approach. The ...
