ABSTRACT
INTRODUCTION: Most of the pregnant women do not achieve the recommended dietary intake of vitamins A and E. These vitamins may counteract oxidative stress involved in some adverse perinatal outcomes. We aimed to assess the associations between maternal vitamin A and E at mid-pregnancy with both maternal and fetal outcomes and to identify possible early biomarkers during pregnancy to predict and prevent oxidative stress in the offspring. METHODS: Data on dietary and serum levels of vitamins A and E were collected from 544 pregnant women from the Nutrition in Early Life and Asthma (NELA) study, a prospective mother-child cohort set up in Spain. RESULTS: There were large discrepancies between low dietary vitamin E intake (78% of the mothers) and low serum vitamin E levels (3%) at 24 weeks of gestation. Maternal serum vitamins A and E at mid-pregnancy were associated with higher antioxidant status not only in the mother at this time point (lower hydroperoxides and higher total antioxidant activity [TAA]) but also with the newborn at birth (higher TAA). Gestational diabetes mellitus (GDM) was negatively associated with maternal serum vitamin A (OR: 0.95 CI: 0.91-0.99, p = 0.009) at mid-pregnancy. Nevertheless, we could not detect any association between GDM and oxidative stress parameters. CONCLUSIONS: In conclusion, maternal vitamin A and E serum levels may be used as an early potential biomarker of antioxidant status of the neonate at birth. Control of these vitamins during pregnancy could help avoid morbid conditions in the newborn caused by oxidative stress in GDM pregnancies.

We present a clinical case of a patient with left renal agenesis and ipsilateral blind hemivagina who also had one or more atretic ectopic ureters opening into supposed mesonephric duct, which in turn opened into, or joined onto, the ipsilateral hemicervix, continuing with the blind hemivagina. The diagram of this complex genitourinary malformation would strongly support our hypothesis of the embryology of the human vagina as deriving from the Wolffian ducts and the Mullerian tubercle.

BACKGROUND: To analyze the therapeutic results of one dose of 3 million IU of recombinant interleukin-2 (rIL-2) left intracyst (group I) versus two doses with a 1-month interval (group II) after transvaginal ultrasound (US)-guided drainage of endometriomas under the effect of GnRH analogues. METHODS: Prospective and randomized clinical trial (helped by a random number table) at a University Hospital. Twenty-four consecutive patients with endometriomas initially sent to us for laparotomy and conservative surgery for endometriosis were included. INTERVENTIONS: Treatment with GnRH analogues every 28 days, 3 doses. Under their effect, one or two transvaginal US-guided punctures were performed in order to aspirate the endometriomas, and 3 million IU of rIL-2 were left in the aspirated cysts each time. CLINICAL RESULTS: two menstruations after GnRH analogues. Other secondary outcome measures were: the time until recurrence of cysts, symptoms and CA-125 >35 U/ml, and the need for further medical or surgical treatment. RESULTS: They were moderate or good in >50% of cases with one drainage and one dose of 3 million IU of rIL-2 intracyst, but were better with a second drainage and two doses of rIL-2 (25 vs. 58.3% 'good results'). There were fewer recurrences and the interval before recurrence was longer after two doses but differences were not significant. Six patients from group I (50%) and 3 from group II (25%) needed laparotomy and conservative surgery at 17.5 +/- 8.7 months (total time of follow-up = 33 +/- 8.8 months). CONCLUSIONS: Treatment of endometriomas with transvaginal US-guided drainage and rIL-2 left in the cysts under endometrial suppressive therapy with GnRH analogues has beneficial effects, improving clinical manifestations and avoiding some surgical therapies. The use of a higher dose of rIL-2 does not produce better results, whereas drainage + rIL-2 twice does.

BACKGROUND: Complex malformations of the female genital tract are often incorrectly identified, treated and reported, probably due to not considering the malformation as a cause of the clinical symptoms and neither the embryological origin of the different elements of the genitourinary tract. METHODS: Complex malformations are studied and classified, and new types are presented. The new types of complex malformations presented are: (i) Cases of unilateral vaginal or cervico-vaginal atresia with renal agenesis and uterine duplication, with or without communication between hemiuteri; (ii) the unilateral Rokitansky syndrome; and (iii) the combination in the same patient of unilateral Rokitansky syndrome (Müllerian defect) on one side and blind vagina and ipsilateral renal agenesis syndrome (Wolffian defect) on the other side. RESULTS: A revised version of the clinical and embryological classification of genital malformations is presented and an associated diagram points out the origin of these malformations. CONCLUSIONS: These genital malformative anomalies reaffirm our hypothesis about the embryology of the human vagina as deriving from the Wolffian ducts and the Müllerian tubercle; and they show that gynecologists should be aware of the related symptoms and the embryology of the female genital tract in order to achieve a better comprehension of the malformations for their right correction or therapeutic approach.
