Folic acid supplementation in pregnancy.
Pregnancy among mothers with spina bifida. Tal vez, sea necesario realizar adaptaciones durante el proceso, pero alienta a tu hijo a ser tan independiente como sea posible. Randomization to undergo either prenatal or postnatal surgery in a 1: Infant secondary outcomes were radiographic appearance of components of the Chiari II malformation, as evaluated by independent radiologists; the time to the first shunt placement or mielomenjngocele the criteria for such placement ; locomotion; the Psychomotor Development Index of the Bayley Scales; scores on the Peabody Developmental Motor Scales; the degree of functional impairment on the basis of physical examination; and the degree of disability, as measured by the WeeFIM Functional Independence Measure for Children instrument.
We randomly assigned eligible women to undergo either prenatal surgery before 26 weeks of gestation or standard postnatal repair.
Mayo Clinic, Rochester, Minn. Trained independent pediatricians and psychologists who were unaware of study-group assignments and who reported directly to the coordinating center conducted the cirugi.
Although the prenatal-surgery group had better outcomes than the postnatal-surgery group, not all infants benefited from the early intervention, and some had a poor neuromotor outcome.

Pathophysiology, prevention and potential treatment of neural tube defects. Prenatal surgery was associated with higher rates of preterm birth, intraoperative complications, and uterine-scar defects apparent at delivery, miepomeningocele with a higher rate of maternal transfusion at delivery. A group sequential method was used to characterize the rate at which the type I error was spent; the chosen spending function was the Lan—DeMets characterization of the O’Brien—Fleming boundary.
Major exclusion criteria were a fetal anomaly unrelated to myelomeningocele, severe kyphosis, risk of preterm birth including short cervix and previous preterm birthplacental abruption, a body-mass index the weight in kilograms divided by the square of the height in meters of 35 or more, and contraindication to surgery, including previous hysterotomy in the active uterine segment.
Human prenatal myelomeningocele repair by hysterotomy was first performed inand bymore than fetuses had undergone the procedure. Solicite una Consulta en Mayo Clinic. We compared continuous variables using the Wilcoxon test and categorical variables using the chi-square test, Fisher’s exact test, or the Cochran—Armitage test for trend. Open neural tube defects: Prenatal surgery also improved several secondary outcomes, including the degree of hindbrain herniation associated with the Chiari II malformation, motor function as measured by the difference between the neuromotor function level and anatomical lesion leveland the likelihood of being able to walk independently, as compared with postnatal surgery.
For the first primary end point, we report the Preterm labor leading to early delivery, placental abruption, and pulmonary edema associated with tocolytic therapy are well-known complications of prenatal surgery.
Espina bífida (para Niños)
The study protocol, including the statistical analysis plan and full inclusion and exclusion criteria, is available with the full text of this article at NEJM. Women in the prenatal-surgery group stayed nearby with a support person until cesarean delivery at 37 weeks of gestation if still undeliveredwhereas women in the postnatal-surgery group went home and returned to the center at 37 weeks for cesarean delivery and postnatal repair by the same surgical team.
Alpha-fetoprotein AFPsingle marker screen, maternal, serum. In the postnatal-surgery group, two neonates died, both with severe symptoms of the Chiari II malformation; both had received shunts.
The composite score for each infant consisted of the sum of the two ranks. The Bayley scores were ranked across all infants, with fetal, neonatal, or infant deaths being assigned the lowest rank. The assessment of the hysterotomy site at the time of delivery revealed thinning or an area of dehiscence in more than one third of the women.

Rei J, et al. National Institute of Neurological Disorders and Stroke. Primary Outcomes Two primary outcomes were prespecified. The severity of the neurologic disability in the lower limbs is correlated with the level of the injury to the spinal cord.
Sleep-disordered breathing in patients with myelomeningocele. The results of this trial should not be generalized to patients who undergo procedures at less experienced centers or who do not meet the eligibility criteria.
In the postnatal-surgery group, seven women chose not to return to the clinical center for delivery, and four were unable to return because of preterm labor or other complications.
The median survival time in open spina bifida. One third of women who underwent prenatal surgery had an area of dehiscence or a very thin prenatal uterine surgery scar at the time of delivery. Early data suggested a dramatic improvement in hindbrain herniation in comparison with historic controls mielojeningocele also showed an increased mirlomeningocele risk, including preterm labor and uterine dehiscence, and a substantially increased risk of fetal or neonatal death and preterm birth.
Fetuses that were treated prenatally were born at an average gestational age of
