Considering IL1's immunomodulatory, proangiogenic and tissue remodeling properties, and its role as an embryonic signal, modulation of endometrial cell responsiveness to IL1 via the concomitant regulation of its own activating and inhibitory receptors and receptor antagonist may represent an important regulatory mechanism of IL1-induced physiological changes occurring in the human endometrium during the normal menstrual cycle and embryo development.
Objective 1. To evaluate the effectiveness of sweeping of the membranes to reduce the need for a formal Design A randomised controlled clinical trial.Setting Three tertiary care hospitals of the province of Quebec, Canada.Population Two hundred women for whom non-urgent induction of labour was medically indicated.Methods Women were randomly allocated to sweeping of membranes, or vaginal examination for Bishop scoring only.Main outcome measures 1. Cumulative incidence and relative risk of induction of labour by either oxytocin, prostaglandins or amniotomy; 2. women's discomfort and side effects attributable to sweeping of the membranes.Results Women allocated to sweeping of the membranes required formal induction of labour less frequently than women in the control group, but this difference was not statistically significant (49% vs 60%, RR 0.83, 95% CI 0.64-1.07). Pain during vaginal examination and other side effects were more frequently reported by women allocated to the sweeping group.
ConclusionsThe observed reduction in the need for formal induction of labour is smaller than in previous studies. Side effects and discomfort associated with sweeping of the membranes must be taken into account when counselling women who require induction of labour.induction of labour; 2. to evaluate the side effects of this intervention.
During a 7-year period, 117 fetal karyotypes were available from 131 genetic amniocenteses. These procedures were performed between 14 and 37 weeks' gestation for the following abnormal ultrasound findings: (1) intrauterine growth retardation (IUGR)--61 cases; (2) fetal malformation--71 cases; and (3) amniotic fluid volume (AFV) abnormality--60 cases. Chromosomal abnormalities were identified in 19 cases (16.2 per cent). Aneuploidy was 2.5 times as frequent in the presence of malformations than in their absence. No correlation was demonstrated between specific fetal malformations and specific chromosomal abnormalities. Aneuploidy was also twice as frequent in the presence of symmetrical IUGR than in its absence. No chromosomal abnormalities were found among eight cases of asymmetrical IUGR. Four cases of aneuploidy presented with isolated IUGR, three of these involving the X chromosome. The frequency of aneuploidy was the same with or without abnormalities of AFV (14.3 versus 16.4 per cent). No chromosomal abnormality was found associated with isolated AFV abnormalities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
