- Abstract
Objective: To assess the efficacy of transcervical resection of submucous fibroids according to type and size., Materials and Methods: Retrospective follow-up of 235 women with submucous fibroids at outpatient hysteroscopy who underwent a hysteroscopic transcervical resection. The main indications were the abnormal uterine bleeding and fertility problems. Thirty-seven percent of patients had an associated endometrial ablation and 32% had a polyp resection. Fifty-one percent of women were menopausal. In cases of incomplete resection a repeat procedure was offered., Results: Intra-operative complications were rare (2.6%) and there was no major complication. Eighty-four percent of cases were followed-up. The median follow-up was 40 months (range 18-66 months). The procedure was classed as a success in 94.4% of patients. Among the cases that were classed as a failure, four patients had a repeated hysteroscopic procedure, three patients had a subsequent hysterectomy and four patients presented with abnormal uterine bleeding at follow-up., Conclusion: The hysteroscopic transcervical resection of submucous fibroids is a safe and highly effective long-term therapy for carefully selected women presenting with abnormal uterine bleeding and fertility problems. It produces satisfactory long-term results with few complications.

- Abstract
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).

- Abstract
Objective: To study the relation between serum human chorionic gonadotrophin (hCG) levels measured at 15-18 weeks and gestational disorders, assess their correlation with the artery uteroplacental Doppler (AUD) at 24 weeks among nulliparas, and assess the predictivity of the hCG/hPL (human placental lactogen) ratio for pre-eclampsia., Study Design: Retrospective study of two groups of women younger than 38 years old: one with an elevated serum hCG level (2 MoM (multiples of the median) or more) and a normal fetal karyotype (group A), and the other with a lower hCG level (group B). Within each group, we studied the nulliparas separately (respectively groups AO and BO). We analyzed the double screening, elevated hCG levels with abnormal AUD, for the predicting of hypertensive disorders., Results: Elevated hCG levels were significantly (p<0.05) more prevalent among women who developed gestational diabetes (groups A and AO) and among nulliparas with pregnancy-induced hypertension and pre-eclampsia (AO). Among nulliparas, the combination of the hCG assay and a subsequent Doppler increased the positive predictive value (PPV) of the assay from 19 to 75%, without reducing its negative predictive value (NPV) for gestational vascular disorders. The hCG/hPL ratio did not improve the predictivity of the hCG assay alone for pre-eclampsia., Conclusions: An hCG level of 2 MoM or more at 15-18 weeks identifies a group of women at risk of gestational vascular disorders; it therefore ought to lead to an AUD at 24 weeks. This double screening should be able to define a population of women at risk of developing a hypertensive disorder, who could thus benefit from a preventive treatment, as aspirin.

- Abstract
Objective: Study of maternal and fetal consequences of lone hyperuricemia during pregnancy and demonstration that lone hyperuricemia is not a risk factor regarding the onset of preeclampsia., Study Design: Retrospective study of two groups of women, one found to have lone hyperuricemia during pregnancy (n=102) and the others with normal serum uric acid levels (n=100)., Results: The only consequence identified of the lone hyperuricemia was a lower birth weight of children born to mothers found to have lone hyperuricemia for more than 2 weeks (P<0.05)., Conclusions: Lone hyperuricemia is not a risk factor regarding the onset of preeclampsia. It is therefore unnecessary to measure serum uric acid level during a normal pregnancy.

- Abstract
Objectives: The aim of this study, initiated in 1982, was to determine the feasibility and the interest of a first-line immunochemotherapy delivered by intraperitoneal (i.p.) and intravenous (i.v.) routes combined in ovarian cancer., Study Design: Eighty-two naive patients with a common epithelial cancer entered the study from January 1982 to December 1990 (median follow up > 70 months). For i.p. infusion, we used a simple lumbar puncture needle left in situ for < 2 h. The first 18 patients received monthly by i.p. route: Adriamycin (DXR) 40 mg/m2, Fluorouracil 1000 mg/m2, Cisplatin (CDDP) 90 mg/m2, Bleomycin 30 mg -DGZ (extract of vibrio cholerae) 60 mg/m2. For the remaining 64 patients Aracytin 500 mg/m2 replaced DXR and the dose of CDDP was more than doubled (200 mg/m2) thanks to the use of sodium thiosulfate. All 82 patients received Ifosfamid 1300 mg/m2 intravenously., Results: Local toxicity consisted in one subcutaneous abscess and one bacterial peritonitis out of 1508 abdominal punctures. Stage III turned out to be the most interesting group to evaluate the efficacy of a first-line protocol. In this group 34 out of 47 patients (72.3%) who underwent an initial incomplete surgery were in complete remission (CR) at second-look. Nevertheless, 21 out of the 34 patients in CR relapsed (61.7%) and 14 died (43.2%)., Conclusion: These results show the efficacy of our regimen administered i.p., and the safety of the delivery by a simple needle which avoids the complications of the implantable systems. Nevertheless, the usefulness of a systematic second-line chemotherapy (Paclitaxel?), despite a prognosis situation as favourable as a CR at second-look, must be taken into consideration.

- Abstract
Objective: To examine if early uterine Doppler remains a predictor of vascular complications in pregnant women treated with low-dose aspirin for a poor previous obstetrical history., Design: A study of the uterine diastolic index and the uterine notch with a continuous wave Doppler ultrasound., Setting: The maternity Hospital Port-Royal Baudelocque Paris, France., Subjects: All pregnant women between 1991-1992 (n = 48) early treated with 100 mg daily of aspirin (15.9 (S.D. = 1) weeks) for a poor previous obstetrical history., Methods: The 48 patients underwent a uterine Doppler examination at 23.8 (S.D. = 2.6) weeks. A diastolic index was calculated and the presence of diastolic notch was noted., Main Outcome Measures: Vascular complications (pre-eclampsia, intra-uterine growth retardation), birth weight., Results: Twenty six patients (54.2%) had an abnormal early uterine Doppler. Nine patients (18.7%) had a vascular complication, which occurred more frequently in pregnant patients with an abnormal uterine Doppler (8/26 vs. 1/22; P < 0.05). The mean birth weight was lower in patients with a pathological uterine Doppler (2419 (S.D. = 679) vs. 2841 (S.D. = 482) g; P < 0.05)., Conclusions: In pregnant, early treated with low-dose aspirin for poor previous pregnancies, early uterine Doppler predicted patients with a high-risk of recurrence of vascular complications.

- Abstract
Between December 1981 and December 1988, 329 consecutive patients with stage I and II breast cancers who underwent wide excision (n = 261) or quadrantectomy (n = 68) with (n = 303) or without (n = 26) axillary dissection were referred to radiotherapy. Final margins of resection were microscopically free from tumor involvement in all cases. Radiotherapy consisted in 40-45 Gy over 4-4.5 weeks to the breast, with (n = 168) or without (n = 161) regional nodal irradiation of 45-50 Gy over 4.5-5 weeks. A mean booster dose of 15 Gy was delivered to the primary site by iridium-192 implant in 169 patients (group 1) or by electrons in 160 patients (group 2). Twenty-seven percent (n = 88) of patients received tamoxifen for > or = 2 years. Adjuvant chemotherapy was administered in 22% (n = 71) of patients. Groups 1 and 2 were not strictly comparable. Group 1 patients were significantly younger, had smaller tumors, were treated with cobalt at 5 x 2 Gy per week and axillary dissection was more frequently performed. Group 2 patients were more frequently bifocal and more frequently treated by quadrantectomy and tamoxifen, and irradiation used accelerator photons at 4 x 2.50 Gy per week. No difference in terms of follow-up and survival rates was observed between the two groups. For all patients the 5- and 10-year local breast relapse rates were 6.7% and 11%, respectively. No difference was observed regarding local control either by the electron or the iridium-192 implant boosts. Axillary dissection and age had an impact on the breast cosmetic outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
Objectives: To characterize women receiving poor antenatal care and assess their perinatal risk., Design: Computerized data., Setting: Public hospital setting Paris (1987-1990). Comparison with representative sample in Ile-de-France region (n = 6423)., Methods: Poor attenders with less than 3 visits (n = 210) were compared with good attenders with 3 visits or more (n = 5631)., Results: Poor attenders were younger and had higher rates of perinatal mortality (4.7%), preterm delivery (Odds ratio 5.2:4.3-6.3) and low birth weight (Odds ratio 4.6:3.7-5.6)., Conclusion: Women with poor antenatal care have a greater risk for adverse pregnancy outcome. This risk cannot be attributed to unfavourable living conditions only.

- Abstract
One hundred thirty-two women between the ages of 19 and 50, with various forms of benign breast diseases received 1 mg promegestone, or 0.5 mg promegestone, or 10 mg lynestrenol daily (double-blind), for 15 days per cycle, during three cycles. The groups were identical before treatment, with the exception of a longer history of mastodynia and mastopathies in the 1 mg promegestone group than in the lynestrenol group (P = 0.04) and a greater proportion of mastosis zones in the lynestrenol group as compared to the 0.500 mg promegestone group (P = 0.05). The effectiveness of lynestrenol both in terms of symptomatology (evaluated as good or excellent in 66.6% of the cases) and of clinical observations (evaluated as good or excellent in 59% of the cases) is not significantly different statistically from that of promegestone at 1 mg, whose effectiveness on symptomatology was good or excellent in 65.9% and 57.1% of the cases, respectively, or from that of promegestone at 0.5 mg/day (with 65% and 51.3% effectiveness, respectively). Clinical tolerance was rated good or excellent for 73.9% of the women on 1 mg promegestone and for 59.5% of the women on 0.500 mg promegestone, compared to 66.7% of the women on lynestrenol. No statistically significant difference was observed, neither between lynestrenol and promegestone 1 mg nor between lynestrenol and promegestone 0.5 mg. This study shows a clear improvement in functional and physical signs in patients treated with promegestone. Promegestone's efficacy is close to that of lynestrenol, a nonsteroidal progestin.2+ off

- Abstract
Perinatal outcome and various indicators of perinatal risk were analyzed in a prospective study of 268 pregnant women with hypertension. Poor perinatal outcome was defined by stillbirth (n = 13), neonatal death (n = 2), and in surviving babies, by birth before 32 weeks or a birthweight below 1500 g (n = 13). In multivariate analysis, proteinuria and onset of hypertension between the 27th and 36th weeks of amenorrhea were the only two independent indicators of poor outcome (relative risks of 4.0 and 3.7, p less than 0.001 and p less than 0.01 respectively). Both these indicators were more frequent in mothers with no history of pre-pregnancy hypertension.
