Postpartum months provide a challenging period for poor women. This study examined patterns of menstrual resumption, sexual behaviors and contraceptive use among urban poor postpartum women. Women were eligible for this study if they had a birth after the period September 2006 and were residents of two Nairobi slums of Korogocho and Viwandani. The two communities are under continuous demographic surveillance. A monthly calendar type questionnaire was administered retrospectively to cover the period since birth to the interview date and data on sexual behavior, menstrual resumption, breastfeeding patterns, and contraception were collected. The results show that sexual resumption occurs earlier than menses and postpartum contraceptive use. Out of all postpartum months where women were exposed to the risk of another pregnancy, about 28% were months where no contraceptive method was used. Menstrual resumption acts as a trigger for initiating contraceptive use with a peak of contraceptive initiation occurring shortly after the first month when menses are reported. There was no variation in contraceptive method choice between women who initiate use before and after menstrual resumption. Overall, poor postpartum women in marginalized areas such as slums experience an appreciable risk of unintended pregnancy. Postnatal visits and other subsequent health system contacts provide opportunities for reaching postpartum women with a need for family planning services. 相似文献

Jejunal diverticulosis is a rare malformation that is often asymptomatic. Complications might be similar to those occurring in large-bowel diverticula but also include a much more particular event: intestinal obstruction due to migration and impaction of enterolith formed inside diverticula. This is a very uncommon entity; diagnosis and management are thus often delayed. Mostly surgical exploration is necessary because obstruction symptoms are unresponsive to medical treatment. The authors report a new case of enterolith ileus in a 74-year-old man, due to jejunal diverticulosis, and its successful surgical management in emergency. Only 39 similar cases have ever been reported in the literature. 相似文献

Ultrasound treatment has been proposed by several authors to enhance the repair of long bone injury. The present study investigated in a murine model the treatment by low-intensity pulsed ultrasound (LIPUS) of calvarial flat bone defect. The animals were operated to create bone defect and exposed to ultrasound for 5 min per day, 5 d per week, during two weeks. Two intensities of ultrasound (1 MHz, 100 Hz pulse repetition frequency and 20% duty cycle) were investigated: 100 and 300 mW/cm2 spatial-averaged, time-averaged. Re-ossification surface and volume were determined after 30 and 60 days using computerized X-ray tomography in all animals of the control and treated groups. The results showed a significant increase of bone re-ossification in the group treated with the higher-intensity ultrasound (mean value of 18% volume reconstruction), whereas lower bone reconstruction was observed in the lower-intensity and control groups (respective mean values of 10 and 12% volume reconstruction).
