Abstract
OBJECTIVES We organized a survey for in-vitro fertilization couples who beneficiated on self-preservation of part of the oocyte cohort. The main objective was to measure couples' satisfaction. Secondary objectives were; to identify how patients had been informed; to verify that the use of the ART technique met their expectations, and how they felt about oocyte or embryo freezing. METHODS The data were collected by a questionnaire sent electronically to couples who had undergone partial vitrification of the oocyte cohort and at least one warming cycle. The questionnaire consisted of 2 components; one for the women and another one for their husband. RESULTS Eighty-eight women and 62 men responded to the survey respectively, representing 50.86% and 35.84% of the targeted patients. They were satisfied with a 90% rate, men and women combined. The information we give in the center is heard by couples and is part of the trust in the medical staff. Men are more worried than women about the risks of stimulation or ovarian pick-up and are not displeased to be called upon for sperm recovery for every attempt at oocyte warming. The ambiguity of the answers on the representation of the embryo confirms what is already described, but is independent of the acceptance of freezing whether it is oocyte or embryo. CONCLUSION In the same way as evaluating the results, the evaluation of patient satisfaction is useful for the implementation of therapeutic strategies and care pathways.

Abstract
Developmental lead (Pb) exposure results in persistent cognitive/behavioral impairments as well as an elevated risk for developing a variety of diseases in later life. Environmental exposures during development can result in a variety of epigenetic changes, including alterations in DNA methylation, that can influence gene expression patterns and affect the function and development of the nervous system. The present promoter-based methylation microarray profiling study explored the extent to which developmental Pb exposure may modify the methylome of a brain region, hippocampus, known to be sensitive to the effects of Pb exposure. Male and female Long Evans rats were exposed to 0 ppm, 150 ppm, 375 ppm, or 750 ppm Pb through perinatal exposures (gestation through lactation), early postnatal exposures (birth through weaning), or long-term postnatal exposures (birth through postnatal day 55). Results showed a significant contribution of sex to the hippocampal methylome and effects of Pb exposure level, with non-linear dose response effects on methylation. Surprisingly, the developmental period of exposure contributed only a small amount of variance to the overall data and gene ontology (GO) analysis revealed the largest number of overrepresented GO terms in the groups with the lowest level of exposure. The highest number of significant differentially methylated regions was found in females exposed to Pb at the lowest exposure level. Our data reinforce the significant effect that low level Pb exposure may have on gene-specific DNA methylation patterns in brain and that this occurs in a sex-dependent manner.

Abstract
AIM This study evaluated the clinical and haemodynamic effects of norepinephrine infusion in preterm infants. METHODS The effects of norepinephrine therapy for refractory hypotension were evaluated in preterm infants between April 2009 and April 2011 at the neonatal intensive care unit of Sainte-Justine Hospital, Montreal, Quebec. Changes in haemodynamics and clinical parameters were analysed eight hours before and eight hours after the start of norepinephrine infusion, and eight hours after its cessation. RESULTS During the study, 30 preterm infants at a mean gestational age of 26.5 ± 2.6 weeks (median: 25.7, 23.4-34) and birthweight of 903 ± 437 g (median 827, 450-2550) received norepinephrine infusion for neonatal septic shock. After eight hours of treatment, mean blood pressure, urine output and FiO2 significantly improved. Eight hours after cessation of norepinephrine infusion, the number of patients treated with other inotropes decreased significantly, 24 patients (80%) had normal mean blood pressure and 27 patients (90%) had normal urine output. CONCLUSION Norepinephrine therapy could be considered to improve blood pressure and urine output during neonatal septic shock in preterm infants. Further studies are needed to prove the efficacy and safety of norepinephrine infusion in neonates.

Abstract
PURPOSE To investigate the factors that potentially lead to brain radionecrosis after hypofractionated stereotactic radiotherapy targeting the postoperative resection cavity of brain metastases. METHODS AND MATERIALS A retrospective analysis conducted in two French centres, was performed in patients treated with trifractionated stereotactic radiotherapy (3×7.7Gy prescribed to the 70% isodose line) for resected brain metastases. Patients with previous whole-brain irradiation were excluded of the analysis. Radionecrosis was diagnosed according to a combination of criteria including clinical, serial imaging or, in some cases, histology. Univariate and multivariate analyses were performed to determine the predictive factors of radionecrosis including clinical and dosimetric variables such as volume of brain receiving a specific dose (V8Gy-V22Gy). RESULTS One hundred eighty-one patients, with a total of 189 cavities were treated between March 2008 and February 2015. Thirty-five patients (18.5%) developed radionecrosis after a median follow-up of 15 months (range: 3-38 months) after hypofractionated stereotactic radiotherapy. One third of patients with radionecrosis were symptomatic. Multivariate analysis showed that infra-tentorial location was predictive of radionecrosis (hazard ratio [HR]: 2.97; 95% confidence interval [95% CI]: 1.47-6.01; P=0.0025). None V8Gy-V22Gy was associated with appearance of radionecrosis, even if V14Gy trended toward significance (P=0.059). CONCLUSION Analysis of patients and treatment variables revealed that infratentorial location of brain metastases was predictive for radionecrosis after hypofractionated stereotactic radiotherapy for postoperative resection cavities.

Abstract
Endoscopic management is the gold standard for symptomatic low-grade vesicoureteral reflux (VUR) in children. Deflux® (hyaluronic acid/dextranomer) injection is highly effective and has very few complications. We report on two cases of secondary megaureter after Deflux® injections. In the first case, a boy presented with Grade 4 VUR. He received a bilateral Deflux® injection with a total of three syringes. The postoperative ultrasound was normal. However, a check-up ultrasound 3 years later showed a significant ureteropyelocalyceal dilatation, with stasis and decreased renal function on scintigraphy, the reason why antireflux surgery (Cohen procedure) was performed. In the second case, a girl diagnosed with bilateral VUR at birth received bilateral injections with one syringe on each side at the age of 12 months. One month later, the ultrasound showed a dilation of the distal ureters (diameter of the right ureter, up to 10mm; left ureter, up to 6.7mm). The child underwent surgery 8 months later (Cohen procedure) because of iterative pyelonephritis and persistent ureter dilatation. Only one previous case has been described in the literature. In our experience, this complication has occurred only twice in 452 injections (4‰). In conclusion, endoscopic treatment with hyaluronic acid/dextranomer injection is a minimally invasive procedure that improves the situation in cases of VUR. It has few complications. Other than failure, there is a low risk of secondary expansion requiring, in our opinion, ultrasound verification over the long term.
