[Effectiveness of Alphastria cream in the prevention of pregnancy stretch marks (striae distensae). Results of a double-blind study]. Stretching of the cervix and stripping of the membranes at term: a randomised controlled study. The cosmetic use of skin-lightening products during pregnancy in Dakar, Senegal: a common and potentially hazardous practice. Prevention of perineal trauma by perineal massage during pregnancy: a pilot study. Single-blind trial addressing the differential effects of two reflexology techniques versus rest, on ankle and foot oedema in late pregnancy.
nan To determine whether routine antepartum stretching of the cervix and stripping of the membranes at term would shorten the length of pregnancies, and whether this correlated with cervical status and fetal and maternal parameters.
                A prospective, randomised, controlled study of 293 term gravidas, free of medical complications, divided into two groups: stretching/stripping, and non-stretching/stripping. Digital separation of the fetal membranes from the lower uterine segment, and cervical stretching, were performed during routine vaginal examination of the first group. In the second group, only routine vaginal examination was performed.
                Of 293 patients, 152 underwent a trial of stretching and stripping; 141 served as a control group. The mean interval (hours to delivery after the procedure) was 136 h (S.D. 10), compared to 161 h (S.D. 11) in the control group (P = 0.095; not significant), but with only a trend towards the shorter interval in the first group. When patients were matched according to weeks of gestation and fetal and maternal parameters, only those at 41 weeks' gestation or more had a significant reduction in the interval from the procedure to delivery (mean 91 h (S.D. 8) compared to mean 125 h (S.D. 10) in the control group; P < 0.007). This observation was independent of cervical status and other maternal or fetal parameters.
                Only patients > or = 41 weeks' gestation benefitted from stretching of the cervix and stripping of the fetal membranes. The effect was not dependent on the cervical status or other maternal and fetal parameters. Many women of childbearing age from sub-Saharan Africa use topical skin lighteners, some of which present a risk of toxic systemic effects. The goals of this study were to evaluate, in this environment, the frequency of this practice during pregnancy, as well as eventual consequences on pregnancy. Ninety-nine women from 6 to 9 months pregnant were randomly selected among those attending a standard maternal centre in Dakar for a prenatal visit. Investigations consisted of questions about the use of skin lighteners, a standard clinical examination, follow-up until delivery and a morning blood sample for plasma cortisol levels. Sixty-eight of the 99 selected women used skin lighteners during their current pregnancy, the main active ingredients being hydroquinone and highly potent steroids (used by 64 and 28 women, respectively). No difference in the main outcomes of pregnancy were found between skin-lightener users and the others; however, women using highly potent steroids, when compared with those who did not, had a statistically significant lower plasma cortisol level and a smaller placenta, and presented a higher rate of low-birth-weight infants. Skin lightening is a common practice during pregnancy in Dakar, and the use of steroids may result in consequences in the mother and her child. Although the performance of perineal massage by a woman or her partner during the last weeks of pregnancy may help to prevent perineal trauma at delivery, the technique has never been evaluated rigorously. This study examined the feasibility of a randomized, controlled trial, and more specifically assessed the participation rate, the acceptability of the intervention, and whether or not an attending physician could remain blind to participants' groups. The pilot study was a single-blinded, randomized, controlled trial. Nulliparous women, 32 to 34 weeks pregnant, were recruited from June 8 to July 31, 1992, at the offices of family physicians and obstetricians who practice at the Hôpital du Saint-Sacrement in Quebec City. Women assigned to the intervention group practiced daily 10-minute perineal massage and completed a diary, and those in the control group had standard care. Women and attending physicians completed a questionnaire about the aspect of blindness. Among the 174 women who delivered during the study period, 104 (59.8%) were approached by a midwife and 46 (26.4%) were randomized. Twenty (91.0%) of the 22 women in the massage group returned their perineal massage diaries. Based on the postpartum questionnaire, 20 women practiced the technique at least four times a week for three weeks or longer. No woman in the control group practiced massage. The attending physician was aware of the woman's group in only three instances (6.7%). Based on the results of this pilot study, a randomized, controlled trial to evaluate the efficacy of perineal massage in preventing perineal trauma at birth appears feasible. This single-blind randomised controlled trial explored the differential effects of two different foot reflexology techniques with a period of rest on oedema-relieving effects and symptom relief in healthy pregnant women with foot oedema. Fifty-five women in the third trimester were randomly assigned to one of the three groups: a period of rest, 'relaxing' reflexology techniques or a specific 'lymphatic' reflexology technique for 15 min with pre- and post-therapy ankle and foot circumference measurements and participant questionnaire. There was no statistically significant difference in the circumference measurements between the three groups; however, the lymphatic technique reflexology group mean circumference measurements were all decreased. A significant reduction in the women's symptom mean measurements in all groups (p<0.0001) was apparent. A 'perceived wellbeing' score revealed the lymphatic technique group (p<0.0001) significantly increased their wellbeing the most, followed closely by relaxing techniques (p<0.001) and then the control rest group (p<0.03). Lymphatic reflexology techniques, relaxing reflexology techniques and a period of rest had a non-significant oedema-relieving effect. From the women's viewpoint, lymphatic reflexology was the preferred therapy with significant increase in symptom relief.
We found no high-quality evidence to support the use of any of the topical preparations in the prevention of stretch marks during pregnancy. There is a clear need for robust, methodologically rigorous randomised trials involving larger sample sizes to evaluate the effects of topical preparations on the development of stretch marks in pregnancy. In addition, it is important that preparations commonly used by women to prevent and treat stretch marks are evaluated within the context of robust, methodologically rigorous and adequately powered randomised trials.
