Placental pathology in relation to the White's classification of diabetes mellitus.
The objective of this study was to investigate various macroscopic and microscopic features of the placenta in pregnancies complicated by diabetes according to White's classification. A total of 148 placentas were studied. Sixty-five were from control patients and 83 from diabetic mothers. ⋯ With accompanying vascular disease the placental weight and neonatal weight were reduced compared to the controls. As a result of increased perinatal jeopardy the rate of operative delivery was higher in diabetic mothers. No major difference was observed in microscopic changes of placentas in different groups according to White's classification and the normal group.

Case ReportsMagnetic resonance imaging in the evaluation of vaginal foreign bodies in a young girl.
A 7-year-old girl with foul-smelling, bloody vaginal discharge for more than 2 years was initially suspected of suffering from vaginal foreign bodies. Although plain radiography revealed no abnormal findings in the pelvis, magnetic resonance imaging (MRI) showed multiple low intensity objects and an intact vaginal wall. Four plastic toys were removed with forceps under general anesthesia. MRI is supposed to be the best technique for evaluating vaginal foreign bodies in young girls.

Randomized Controlled Trial Comparative Study Clinical TrialRandomized controlled trial of 50 and 100 mcg of misoprostol for induction of labor at term.
To compare the safety and efficacy of two different regimens of misoprostol for labor induction at term, we conducted a randomized controlled trial on women presenting for induction of labor at > or =37 weeks' gestation. Eligible women were randomized to receive intravaginal misoprostol 50 microg every 4 h or 100 microg every 6 h until any of the following: 1) adequate contraction pattern (3 contractions/10 min); 2) dilatation >3 cm; 3) artificial rupture of membranes; or 4) signs of uterine hyperstimulation. Use of oxytocin during labor was at the discretion of the managing clinician. ⋯ The mean+/-standard deviation time to delivery (hours) (11.9+/-7.3 vs 14.3+/-9.6 h, p=0.30) and cesarean section rate (35% vs 19%, p=0.30, relative risk: 1.8, 95% confidence interval 0.7-5.4) were not different in the 100 vs 50 microg group. Power analysis demonstrated that 132 women would be required in each group to achieve statistical significance in the primary outcome measure (alpha=0.05, beta=0.80). Similarly, rates of 5-minute Apgar scores <7 (4% vs 3%, p=1.0), and of meconium passage (17% vs 25%, p=0.73) were not significantly different between the two groups.

Extra-strong graduated compression stocking reduces usage of vasopressor agents during spinal anesthesia for cesarean section.
Because a standard type of graduated compression stocking is not effective for the prevention of spinal anesthesia hypothension during cesarean section, we have used an extra-strong type of graduated compression stocking. This study examined whether the extra-strong stocking reduces usage of vasopressor agents. Forty-eight and 47 full term parturients were fitted with the standard stocking and the extra-strong stocking, respectively. ⋯ The mean dose of ephedrine injected during anesthesia was 12.2 and 4.3 mg, and the incidence of ephedrine injected was 85 and 49%, in the standard and extra-strong stocking groups, respectively. The extra-strong stocking group showed significantly lower values. Fitting the extra-strong stocking on both legs for cesarean sections undergoing spinal anesthesia reduced usage of vasopressor agents, suggesting a promising use of this stocking for non-invasive prophylaxis.

Clinical TrialPain relief in labour by transcutaneous electrical nerve stimulation (TENS).
For several years Transcutaneous Electrical Nerve Stimulation (TENS) has been used in the management of chronic and acute pain. The aim of this trial was to determine its effectiveness in providing pain relief during labour as well as its influence on the incidence of requests for epidural analgesia. The experimental group (receiving TENS by a burst - conventional obstetric TENS-apparatus) and the control population (not receiving TENS) consisted of 24 and 35 women respectively. ⋯ Two days postpartum the parturient's satisfaction was evaluated by two questions, a procedure which revealed that 96% degree of satisfaction. The incidence of epidural analgesia in the experimental group was compared to the control-group. During TENS application the pain scores were significantly lower (p<0.0001), but no statistically significant difference in incidence of epidural analgesia was found between the experimental group and the control group.
