RESUMO
OBJECTIVE: The aim of this study was to evaluate pregnancy complications and obstetric and perinatal outcomes in women with twin pregnancy and GDM. STUD DESIGN: An observational multicentre retrospective study was performed and 534 pregnant woman and 1068 twins infants allocated into two groups, 257 with GDM and 277 controls, were studied. MAIN OUTCOME MEASURES: Pregnant women characteristics, hypertensive complications, preterm delivery rate, mode of delivery and birthweight were analysed. RESULTS: Pregnant women with GDM were older (p < 0.001) and had higher body mass index (p < 0.001) than controls. GDM was associated with higher risk of prematurity in twin pregnancy (odds ratio 1.64, 95% confidence interval [1.14-2.32], p = 0.005). This association was based on the association with other pregnancy complications. Birthweight Z-scores were significantly higher in the GDM group (p = 0.02). The rate of macrosomia was higher in the GDM group (p = 0.002) and small for gestational age (SGA) babies were significantly less frequent (p = 0.03). GDM was an independent predictor of macrosomia (p = 0.006). CONCLUSION: The presence of GDM in twin pregnancy was associated with a higher risk of hypertensive complications, prematurity and macrosomia, but significantly reduces the risk of SGA infants. Prematurity was related to the presence of other associated pregnancy complications.

BACKGROUND/PURPOSE: Recent experience in fetal surgery to correct myelomeningocele in humans reports an early reversion of hydrocephalus and decreased need of ventricular shunting in the first months of life; however, it has not been possible to demonstrate benefit in lower extremity function. In the present work, we have tried to ascertain the impact of cord exposure on hind limb function. METHODS: Fetal rabbits with myelomeningocele (group M), treated myelomeningocele (group T), and control animals (group C) were compared at birth regarding physical examination, somatosensory-evoked potentials of the hind limbs, ventricular morphometry, and spine histology. RESULTS: No major difference was found between groups M and T in the physical examination. Somatosensory-evoked potentials of the hind limbs were absent in group M and present in group T, although showing a longer latency period and decreased amplitude than controls. The area of the third ventricle was significantly larger in group M than in group C; in group T, it was also somewhat larger but not significantly so. Cord histology had evident changes in group M and minor changes in group T, which resembled normal group C cord. CONCLUSIONS: Prenatal covering of the spinal cord prevents central and peripheral neurologic deterioration in this animal model of myelomeningocele.
