A case of successful gonadotropins ovulation induction and donor artificial insemination (AID) followed by a complication of hydatidiform mole is presented. A review of the published papers related to this topic are commented. The organization of a world registry of AID depending on the World Health Organization is encouraged.
There have been five confirmed cases of severe Chlamydia psittaci infection during pregnancy, three having been treated in Edinburgh, Scotland. The most recent case is presented and previous experience is reviewed. The illness usually causes thrombocytopenia with disseminated intravascular coagulation, renal failure and hepatic dysfunction during the late second and early third trimester. The outcome for the fetus is usually fatal and the infection only resolves after delivery or abortion. The main hope is for education to prevent infection occurring in susceptible populations.
While genital tract infections with Haemophilus influenza (H. influenzae) are recognized with increasing frequency, this organism still remains an uncommon cause of maternal infection. The association of this pathogen with spontaneous abortion is extremely rare and has been described only in cases of midtrimester abortion. We report a case of H. influenzae bacteremia following first trimester spontaneous abortion and review the literature.

The value of plasma hCG determinations (based on the recognition of beta-subunit of hCG) and ultrasound was examined in 48 cases of suspected ectopic pregnancy. In 11 patients with the final diagnosis of ectopic pregnancy (23%), the plasma hCG was clearly subnormal (0.37-3.96 IU/ml), with only one exception, where a normally developed fetus was operated from the fallopian tube (hCG 21.1 IU/ml in the 8th wk). The plasma hCG lvels allowed differentiation of the non-pregnant cases from the normal intrauterine pregnancies and the ectopic cases, but not ata all between the different forms of intrauterine early pregnancy failures and ectopic pregnancies. By ultrasound, however, it was possible to reliably diagnose intrauterine pregnancies from the 7th wk of amenorrhea onwards, and to classify them into the normal and pathological subgroups. The direct demonstration of ectopic pregnancy by ultrasound is problematic, but the exclusion of intrauterine pregnancy by this method, combined with the simultaneous plasma hCG determination by sensitive and rapid method, can be recommended for primary examinations in suspected ectopic pregnancy.
A case report of extended placental retention and subsequent intra-uterine adhesions is presented. Three months after a second trimester abortion, ultrasonography was used to confirm the diagnosis of placental retention and to guide emptying of the uterus when normal curettage had failed. Later ultrasonic guidance was also used in the application of an IUD for the treatment of intra-uterine adhesions.
A case of gestational implantation upon a submucosal cellular leiomyoma in a 43-year-old woman is presented. The resulting histologic picture resembled placental site trophoblastic tumor (PSTT). In immunoperoxidase studies, tumor cells were positive for desmin and vimentin and negative for human placental lactogen and human chorionic gonadotropin, thus supporting a smooth muscle origin. This case demonstrates an unusual histological picture occurring in a setting that might lead to diagnostic confusion and is one in which immunohistochemical evaluation proved to be of great utility.
Female marmoset monkeys that are actively immunised against hCG beta-subunit remain infertile while antibody titres are high. With declining antibody levels the animals experience recurrent abortions that occur progressively later as the levels continue to wane. After booster immunisations the animals become infertile once more. The affinity and total binding sites of antibodies to beta-hCG were monitored after booster injections in marmosets and the values were correlated with subsequent reproductive events. The relationship between antibody amount and affinity varied considerably and the affinity was the important factor in producing the biological effects, pregnancies being often associated with a fall in antibody affinity. The antisera were also biologically active in inhibiting hCG-induced ovulation and increase in uterine weight in mice. There was no apparent cross-reaction between the antisera and human luteinizing hormone as tested by indirect immunofluorescence on adult human pituitary sections.

Haemophilus influenzae was isolated in pure or predominant culture from genital specimens from nine females and two males. Four of the females had vaginitis, two had IUD-related endometritis, one had an incomplete septic abortion, and one had probable urethral syndrome. Two males had urethritis.
OBJECTIVE: The purpose of this study was to evaluate the effectiveness of misoprostol that is administered intravaginally for uterine evacuation in patients with early pregnancy failures. STUDY DESIGN: From March 2001 through March 2003, we treated 41 patients who had early pregnancy failures with vaginal misoprostol, 800 microg. A second course of misoprostol was administered if uterine evacuation did not occur in 24 hours. Patients who had no response to misoprostol underwent a surgical curettage. Our principal outcome measures were the percentage of patients who had successful evacuation of the products of conception and the frequency of adverse drug effects. RESULTS: Twenty-six patients had successful uterine evacuation with a single course of misoprostol; 6 patients required a second course. The overall success rate was 78% (95% CI, 63, 88). No patient experienced a serious adverse drug effect. CONCLUSION: Intravaginal misoprostol is a safe, effective alternative to surgical curettage for the treatment of early pregnancy failure.
The phenomenon of implantation anchors the embryo into the uterine wall and produces a hemochorial placenta that maintains the pregnancy and fetal growth. Implantation and placentation are intimately linked and cannot be dissociated either in time or in space. Preeclampsia is characterized by hypertension and proteinuria. It is secondary to an anomaly of the invasion of the uterine spiral arteries by extra-villous cytotrophoblast cells, associated with local disruptions of vascular tone, of immunological balance and inflammatory status, and sometimes with genetic predispositions. Preeclampsia is a disease of early pregnancy, a form of incomplete spontaneous abortion, but is expressed late in pregnancy. Aspirin may play a favorable role in implantation which is related to the genesis of preeclampsia and some cases of intra-uterine growth restriction. The most important points in obtaining a preventive effect from low-dose aspirin during the pregnancy are early treatment (before 13 weeks of gestation) and the prescription of a sufficient dose (more than 100 mg per day).
STUDY OBJECTIVE: To explore the effectiveness (success, safety, and complications) of a novel technique of gestational sac aspiration in the management of early pregnancy failure as an alternative to dilation and evacuation (D&E) and conservative management. DESIGN: Prospective historical cohort study comparing effectiveness of gestational sac aspiration (study group) to conservative management (control group) with follow-up until negative quantitative beta human chorionic gonadotropin testing is achieved (Canadian Task Force classification II-1). SETTING: An infertility treatment center. PATIENTS: Among 60 women with failed early pregnancies that were achieved by in vitro fertilization or intrauterine insemination, 20 underwent gestational sac aspiration, whereas 40 chose conservative management. INTERVENTIONS: Gestational sac aspiration was done by transvaginal ultrasound-guided needle aspiration under conscious sedation. Aspirated tissue was sent for karyotyping. Both study and control (conservative management) groups received close follow-up with ultrasound and serial beta human chorionic gonadotropin measurements. MEASUREMENTS AND MAIN RESULTS: There was no significant difference in age, infertility factor, or treatment between study and control groups. Mean gestational age was 8 versus 6 weeks in study and control groups, respectively (p < .05). One and 11 patients required D&E in the study and control groups, respectively (p < .05). Karyotyping was successful in all except one patient in the study group. Chromosomal abnormalities were found in 36% of products of conception. No significant complications occurred CONCLUSION: Gestational sac aspiration is a simple and safe outpatient technique that is more effective than conservative management of early pregnancy failure and less invasive than D&E. Moreover, the technique provides a high probability of obtaining a noncontaminated adequate gestation tissue sample for chromosomal study.
Irregular vaginal bleeding is a common symptom of women seeking gynecologic care. Etiologies of irregular vaginal bleeding can be classified into the following categories: pregnancy related (retained products of conception, threatened or missed abortion, or ectopic pregnancy), hormonal (disorders of ovulation, menopause, or hormonal contraceptive use), structural (polyps, myomas, or arteriovenous malformation), neoplasm (endometrial cancer), and infection (endometritis). After the history and physical examination, the initial evaluation of irregular vaginal bleeding has traditionally involved an endometrial biopsy. Transvaginal ultrasound has revolutionized the evaluation of the gynecologic ultrasound examination by providing a minimally invasive means to determine the etiology for the bleeding. Transvaginal ultrasound assessment of the endometrial cavity allows treatment to be tailored to the specific cause of irregular vaginal bleeding, thus saving women time, money, and exposure to unnecessary interventions. The purpose of this article is to give the clinician critical information regarding the capabilities of ultrasound to evaluate women with irregular vaginal bleeding.
OBJECTIVE: The purpose of this study was to determine the reliability of ultrasonographic examination in the clinical management of spontaneous abortions thought to be complete. STUDY DESIGN: Patients with clinical findings suggestive of complete spontaneous abortion were managed prospectively on the basis of ultrasonographic results. Patients with an "empty uterus" were managed expectantly; those with a thickened endometrium or echoes consistent with retained tissue were subjected to curettage. RESULTS: Forty-eight of 49 (98%) patients with an "empty uterus" by ultrasonographic examination had an uneventful recovery without curettage. Nine of 13 (69%) patients with a thickened endometrium or evidence of retained tissue on ultrasonography had chorionic villi obtained by curettage. CONCLUSION: Ultrasonography is a highly reliable test in the management of women thought to have complete spontaneous abortion.

OBJECTIVE: To describe a simple and previously unreported treatment for retained fetal bone fragments as a cause of secondary infertility. SETTING: Fertility center at a Canadian teaching hospital. DESIGN: Case report. PATIENT(S): A 36-year-old woman with a 15-year history of secondary infertility. INTERVENTION(S): A second dilation and curettage (D+C) performed under abdominal ultrasound guidance was performed where the curette could be directed for the removal of echogenic endometrial foci. MAIN OUTCOME MEASURE(S): Resolution of long-term infertility. RESULT(S): Spontaneous pregnancy 4 months after ultrasound-guided D+C and subsequent term delivery. CONCLUSION(S): If an echogenic area is discovered in the endometrium, it is now standard to look at the uterine cavity by hysteroscopy. However, if the hysteroscopy is normal, we suggest that a D+C with intraoperative abdominal ultrasound assistance be done to ensure that all the abnormal tissue is removed.
