We compared the efficacy of misoprostol with that of prostaglandin E2 in cervical ripening and labour induction. Thus 238 women with rupture of membranes beyond 36 weeks gestation without labour were randomized to receive 50 microg misoprostol vaginal gel or 5 mg of prostaglandin E2 gel. Bishop score was evaluated before drug application and 6 hours later. Clinical data and perinatal outcome were recorded. Mean time from induction to delivery and the need for oxytocin were significantly less in the misoprostol group. There were no significant differences in spontaneous labour rate, type of delivery and perinatal outcome. It is concluded that intravaginal misoprostol is safe and more effective than prostaglandin E2 for preinduction cervical ripening in premature rupture of membranes beyond 36 weeks gestation.

The internet of things (IoT) is the notion of all devices and products being connected to the internet rather than only computers and mobile devices as has been the case until the recent past. The IoT is already booming, and its adoption will only accelerate in coming years. At the same time, the world continues to go wireless. Wired internet and telephone connections are becoming rarer with each passing year, and consumers expect and demand wireless communications. One critical enabling technology for the IoT is wireless communications: IP-cameras, printers, kitchen appliances, and more deliver greater flexibility in their design when they do not need a wired connection to access the internet. In this paper, a flexible spectrum management framework to enable greater innovation, investment, and flexibility in IoT products, as well as the necessary architecture that will enable a wider deployment of IoT, is proposed. An illustration and analogy from the success of the unlicensed bands used for wi-fi technology and the accompanying supporting organizations that enable wi-fi's success are drawn.
