Oral mifepristone 600 mg and vaginal gemeprost for mid-trimester induction of abortion: An open multicenter study

This open multicenter study was performed in 20 hospital gynecological units in the UK. The effects of 600 mg oral mifepristone as pretreatment to vaginal prostaglandin induction of second second trimester abortion was studied in 267 women.

The primary efficacy variable was the abortion induction interval, defined as the time taken to expel the fetus from the time of administration of the first prostaglandin pessary. Induction was commenced 36 to 48 hours following mifepristone intake.

The mean abortion induction interval was 7 h. A total of 81.9% of women aborted within 12 h. There was a significant relationship between abortion induction interval and age of gestation, and a significant inverse relationship between abortion induction interval and parity.

Vomiting, pelvic pain, and nausea were the most frequently reported adverse events. Two patients required transfusion and one patient with a uterine scar from a previous cesarean section suffered a ruptured uterus and hysterotomy.     

Screening and treatment of bacteriuria in pregnancy and postpartum period

The paper gives an overview of today's knowledge of urinary tract infection in pregnancy and different treatment procedures. Three different studies of urinary tract infection (UTI) in pregnancy and the postpartum period are reported. Urinary screening of 1798 pregnant women showed a cumulative frequency of bacteriuria of 4.8%, recurrent infection in one-fifth of the cases, and pyelonephritis in 0.6%. Chlamydial infection was observed as a cause of dysuria in pregnancy. In the postpartum period bladder bacteriuria was demonstrated in 3.7%. The condition persisted in 27%, while short-course treatment had significant effect.Presented at the Zambon Symposium on Bacteriuria in Pregnancy, International Urogynecological Association Annual Meeting, Riva del Garda, Italy, September 13, 1989.     

Interaction of Heparin With Antiphospholipid Antibodies (APA) From the Sera of Women With Recurrent Pregnancy Loss (RPL)

PROBLEM: To determine if heparin may act directly with antiphospholipid antibodies (APA) to prevent recurrent pregnancy loss (RPL). METHOD: Patients were seen at the University of Texas Southwestern Medical Center. Twenty women with a history of RPL (≥3 miscarriages), positive APA, and an otherwise normal evaluation were treated with heparin in two daily subcutaneous dosages during a successful pregnancy. APA levels were obtained prior to conception and again at 6, 20, and 30 weeks. RESULTS: Heparin reduced APA binding to cardiolipin and phosphatidylserine in a dose-dependent fashion in ELISA. Heparin affinity chromatography absorbed over 80% of the IgG anticardiolipin antibody in serum from women with high levels of APA. Women treated with increasing dosages of heparin during pregnancy had inversely decreasing levels of IgG anticardiolipin antibody. CONCLUSION: Heparin may act by directly binding APA in vivo, thereby decreasing the adverse effects of APA in women with APA associated RPL.     

Successful triplet pregnancy in a patient with a unicornuate uterus with a cavitary communicating rudimentary horn

In a patient with primary infertility, ovulation was inducedby monitored stimulation with human menopausal gonadotrophins(HMG) because of polycystic ovarian disease. Infertility work-uphad shown a unicornuate uterus with a cavitary communicatingrudimentary horn. The husband showed a varicocele-related moderateoligoasthenoterato-zoospermia. A triplet pregnancy occurredin a third HMG ovulation induction cycle combined with intra-uterineinsemination of the husband's washed semen. The pregnancy wascarefully monitored, and measures to prevent premature deliverywere taken. Because of the patient's obvious discomfort in thepresence of premature labour, Caesarean section was performedat 33 weeks gestation and three healthy infants were delivered.This is the first report of a successful triplet pregnancy ina women with a unicornuate uterus. The reproductive and obstetricoutcome of this condition in general, and in the case of multiplepregnancy, is discussed.     

The biomechanics of vibration and low back pain

This work is a review of the mechanical factors related to low back pain production in a vibration environment. The sitting posture is an extreme orientation for the lumbar intervertebral disc that 1) increases its internal pressure, 2) increases its anteroposterior shear flexibility, while: 3) decreasing its resistance to buckling instability and 4) stressing the posterior region of the disc. Vibration is an additional mechanical stressor. Several studies suggest that the following preventive measures be taken to reduce the risk of low back pain due to driving: 1) minimize the vibration reaching the driver, 2) avoid lifting or bending immediately following driving, and 3) walk around for a few minutes following driving. © 1993 Wiley-Liss, Inc.     

25例IUD及输卵管结扎与异位妊娠的临床分析

米非司酮保守治疗异位妊娠30例疗效观察

应用米非司酮治疗早期异位妊娠30例，结果术非司酮组的治愈率76.67％．与MTX对照组对比无显著差异（P＞0．05）；米非司酮的治疗效果随治疗前血β-HCG的水平增加而递减，增加米非司酮总用量不能提高治愈率，对妊娠囊已形成的早期异位妊娠，药物保守治疗效果较差．
