Termination Process

Background. Fibroids, which can impact pregnancies at later gestations, such as obstructing delivery, may also affect the pregnancy termination process. Case. We present the case of a 28-year-old G1 at 18 weeks who consented for a genetic pregnancy termination via dilation and evacuation. During the typical preparatory procedure with laminaria, it was noted that a 5-6cm cervical fibroid prolapsed into the vagina obstructing access to the uterine cavity. Through osmotic dilation followed by cervical Foley catheter ripening, a planned myomectomy was possible with minimal blood loss prior to uterine evacuation. Conclusion. Through appropriate counselling, planning, and effective cervical dilatation, a planned myomectomy for prolapsing fibroids at the time of termination of pregnancy is possible. This can prevent unnecessary hysterotomy and avoid need for subsequent cesarean section.

ABSTRACT The role of luteinizing hormone (LH) for the maintenance of pregnancy, parturition and lactation was investigated by immunological and histochemical methods in the rat. Neutralisation of endogenous rat-LH with Rabbit-Anti-Bovine-LH-Serum (selective hypophysectomy) from days 7-12 of pregnancy resulted in reabsorption of the foetuses and the reappearance of strong 20α-hydroxysteroid-dehydrogenase (20α-OHSD) activity in the corpora lutea (CL) of pregnancy, which normally show no such activity at that time. This effect could be prevented in part by concurrent pregnenolone administration and fully by progesterone, but was not influenced by oestrogen or prolactin. It is concluded that in early pregnancy LH is the main luteotrophic hormone in the rat even though prolactin might act synergistically with it. Antiserum treatment after the 12th day of gestation had no influence on the state or duration of pregnancy or on parturition. LH-injections during the first half of pregnancy had no luteolytic effects i. e. they did not activate 20α-OHSD activity. After day 16 they advanced the reappearance of the enzyme, but delayed parturition or resulted in stillbirths. Neither LH nor antiserum seemed to alter lactation. Since progesterone prevented both the termination of pregnancy and the recurrence of 20α-OHSD activity, it should have some regulatory properties on the enzyme. It is discussed whether the gonadotrophin-dependent progesterone level could regulate the 20α-OHSD activity rather than result from it.
