[Management of cervical intra-epithelial neoplasm during pregnancy].

Approximately 30% of women diagnosed with cervical cancer are in their childbearing years. Prenatal care provides an excellent opportunity for cervical cancer screening. The incidence of abnormal Pap smear has been reported in 5-8% of pregnant women. But we must know that Pap smears have cytologic modifications because of pregnancy. All abnormal smears have to be referred to colposcopic examination. The squamocolumnar junction is visualized in almost 100% of cases. The sensitivity of colposcopy is nearly 87% with complete concordance in 72.6%. Colposcopically directed biopsies have a good correlation with the final diagnosis with very minimal risks for both mother and fetus. The high rate of complications (hemorrhage, abortion, premature labor) and residual lesions in half of cases do not encourage conization during pregnancy. The final treatment is carried out after delivery. The only absolute indication for conization in pregnancy is to rule out microinvasive disease or make the diagnosis of invasive carcinoma when such a diagnosis will alter the timing of delivery but also when there is a no satisfactory colposcopy and a high-grade Pap smear. In these cases conization is performed for diagnostic and not therapeutic purpose. We must be aware of the high rate of loss of follow-up (6-33%).

[Voluntary interruption of pregnancy: comparative study between 1982 and 1996 in the main center of Côte d'Or. Study of women having repeat voluntary interruption of pregnancy].

UNLABELLED: Since the egal use of induced abortion (1975), all the studies have shown a relative stability of the abortion rate related to delivery. Otherwise since 1985 we have noted an increase of repeat abortions. OBJECTIVE: We compared in same center two populations of aborters with a fifteen year's interval. Then we analysed the psyco-social conditions of patients who had more than one abortion (R). METHODS: It was a comparative study between 1982 and 1996 in the main center of Côte d'Or (France). A representative sample of patients coming for abortion was retrospectively compared, (348 for 1982 and 343 for 1996). RESULTS: There were more not married patients (p = 0.0003), more nulliparous women (p = 0.0017) and more nulligestities' one (p = 0.03) in 1996 than 1982. The interval between the previous pregnancy and in 1996 (p = 0.03). Repeat abortions (R) represented 15.8% in 1982 and 21.6% in 1996. Women who have had two or more abortions had increased significantly between 1982 (1.4%) and 1996 (5.2%) (p = 0.013). The R patients had more living children than patients who accessed for the first time at abortion (noR) in the two periods (p = 0.0003) and there were more women less thirty years old in the R group in 1996 than in 1992 (p < 0.05). The R mean age for the first abortion and for the first pregnancy were lower than the noR group in 1996: respectively 23.7 years versus 27.4% years (p = 0.00009) and 20.8 years versus 23.7 years (p = 0.0001). There were no significant difference between R and noR groups with regards of contraceptive failing, the reasons of abortion and the socio-professional categories. CONCLUSIONS: There were no difference in the number of abortion between 1982 and 1996. However we noted an increase of repeat abortion. This group was characterised by great socio-economic problems, unstable couples and ambivalence with wish of pregnancy and no wish of children. It seemed exist a real psycho-social precariousness. Actually, this population was perfectly aware of contraceptive methods.

Pre-clinical study of the epinephrine-cisplatin association for the treatment of intraperitoneal carcinomatosis.

We have previously shown that intraperitoneal (i.p.) epinephrine enhances tumour penetration and anti-cancer activity of i.p.-administered cisplatin in rats with peritoneal carcinomatosis. Here, we show a direct correlation between the i.p. epinephrine concentration and cisplatin accumulation in rat peritoneal tumour nodules up to a concentration of 5 mg/l. This concentration leads to a maximal 3.7-fold increase of tumour platinum content and a maximal vasoconstriction of the peritoneal and tumour superficial microcirculation when registered by a laser doppler probe. Further, epinephrine half-life was 20.8+/-3.6 min in the peritoneal cavity of two laparotomized pigs. In these animals, epinephrine plasma concentration, heart rate and systolic blood pressure were dependent on the intraperitoneal dose of epinephrine, and life-threatening signs were not observed in either animal. In conclusion, a 5 mg/l concentration of epinephrine could be safely maintained in peritoneal fluid by regular replacement. This concentration is sufficient to maintain a constant vasoconstriction of the peritoneal and tumoral microvascular bed, and enhance the slow diffusion of cisplatin into peritoneal tumour nodules in the course of per-operative intraperitoneal chemotherapy.

Transabdominal amnioinfusion to avoid fetal demise and intestinal damage in fetuses with gastroschisis and severe oligohydramnios.

BACKGROUND/PURPOSE: Despite dramatic improvement in survival rate for neonates with gastroschisis, significant postoperative morbidity and a low mortality rate still occur. Furthermore, even in recent publications, some fetal death has been reported. Does this mean that antenatal diagnosis of gastroschisis is a missed opportunity? In fact, decreased amniotic fluid (AF) volume is observed in some fetuses with gastroschisis. However, oligohydramnios is associated with an increased risk of fetal suffering. When severe oligohydramnios is observed, intrapartum amnioinfusion, to restore AF volume, may help avoid fetal complications. METHODS: Two fetuses with gastroschisis and severe oligohydramnios were treated antenatally with amnioinfusion of saline solution. In one case, fetal heart beat decelerations were observed at 27 weeks' gestation among with the oligohydroamnios and serial transabdominal amnioinfusions were performed. In the second case, severe oligohydramnios was observed at 31, weeks and an amnioinfusion was performed. The 2 babies were delivered at 31 and 34 weeks, respectively. RESULTS: In both cases, exteriorized bowel was nearly normal at birth, and primary closure could be performed. Outcome was favorable, and they were discharged home on day 43 and day 54, respectively. CONCLUSIONS: Because fetuses with gastroschisis and oligohydramnios are part of a particular high-risk group, serial ultrasound examination and computerized fetal heart beat monitoring are necessary during the third trimester. In selected cases of gastroschisis associated with severe oligohydramnios, serial amnioinfusion may be required.

Severe fetal cytomegalic inclusion disease after documented maternal reactivation of cytomegalovirus infection during pregnancy.

Recurrent cytomegalovirus infection during pregnancy is considered less dangerous for the fetus than primary infection. We present a case of severe fetal cytomegalic inclusion disease after maternal reactivation of cytomegalovirus during the first trimester of pregnancy. The possibility of such fetal injury is an argument for prenatal diagnosis in seropositive pregnant women when ultrasonographic findings suggest cytomegalovirus infection.

[What are the current limits for prematurity?].

HIGH PREVALENCE: Over the last 15 years, there has been a 2-fold rise in the prevalence of early prematurity (birth before 33 weeks gestation) and very early prematurity (birth between 22 and 28 weeks gestation). More than 7000 infants weighing between 500 g and 1500 g are born alive each year. Survival rates above 50% at 25 weeks, 86% at 29 weeks and 96% at 32 weeks are reported. These infants have the same right to adapted care as any other person. Nevertheless, maternal risks and the fact that these early and very early premature infants account for less than 1% of all births and yet include 50% of all neonatal deaths and 50% of all sequelae. A multidisciplinary approach is crucial for women with a high risk of delivery before 27 weeks gestation. ASSESSING PROGNOSIS: These infants comprise a very heterogeneous group of patients. Their survival and prognosis depends on many different factors. Antenatal factors include gestational age, estimated fetal weight, presence or not of malformations or fetal hypotrophy, and premature rupture of the membranes. During the perinatal period, antenatal corticosteroid therapy, pre-birth referral to a maternity ward with a pediatric intensive care unit, and care and degree of baro-trauma at delivery are essential. The neonatal assessment may lead to discontinuing treatment in case of extensive neurological damage. OPTIMAL CARE: With optimal care, achieved with an organized perinatal network using well-defined criteria for maternal referral, it should be possible to save 650 more children each year and reduce the number of severe handicaps by 390 among infants born before 33 weeks gestation. PREVENTION: Considerable progress has been made in perinatology, but simple and effective preventive measures must not be overlooked: reduction in the number of multiple pregnancies, detection of socio-demographic risk factors, treatment of asymptomatic bacteriuria, early diagnosis of threatening premature birth.

Chorioamnionitis with intact membranes caused by Capnocytophaga sputigena.

We report a case of chorioamnionitis with intact membranes caused by Capnocytophaga sputigena. The pregnant woman was hospitalised in preterm labor without fever, neither tenderness, just regular contractions. In spite of the tocolitic treatment the patient gave birth to a girl at 29 weeks' gestation, weighing 1220 g and transferred to intensive care. The newborn had clinical and biological signs of infections and was initially treated by Ampicillin, cephalosporin and metronidazol. Capnocytophaga sputigena was found on membranes, cord, amniotic fluid and placenta. It was also identified in maternal endocervix culture. Histologic findings showed a focal chorioamnionitis. This was the fourteenth reported case of infection due to Capnocytophaga species occurring in pregnancy. All the cases are reviewed.

Preoperative radiotherapy and surgery for endometrial carcinoma: prognostic significance of the sterilization of the specimen.

INTRODUCTION: We report a retrospective study on the analysis of the operative specimen after preoperative radiotherapy for FIGO (1971) stage I or II endometrial carcinoma. METHODS AND MATERIALS: From 1976 to 1996, 221 patients were treated with external radiotherapy (XRT) and/or low-dose-rate brachytherapy (BT) followed by surgery (S). Patients with cervical involvement (89 patients) or with high-grade tumors (49 patients) received XRT and BT. Patients stage FIGO Ia (89 patients) or with low-grade tumors (57 patients) received BT alone. Surgery was performed 5 to 6 weeks after irradiation. RESULTS: The mean follow-up is 78 months (12-216). The 5-year survival was 90% for FIGO Ia, 80% for FIGO Ib, and 84% for FIGO II (p = 0.51). According to the differentiation, 5-year survival was 87% for grade 1, 84% for grade 2, 84% for grade 3 (p = 0.10). Grade 3 complications were registered in 2% (no grade 4). The tumors were sterilized in 37 patients (17%), sterilized but with dystrophic glands in 34 patients (16%), only modified and altered in 21 patients (9.5%), with viable cells in 56 patients (26%). After preoperative radiotherapy, 37/148 specimens were sterilized (25%), 14/74 after brachytherapy and surgery (19%), 23/74 after external radiotherapy-brachytherapy and surgery (31%). According to the response of the specimen, 5-year survival was 87% when the tumor was sterilized, 96% when altered glands were present, 85% when modified, and 76% if residual tumor with viable cells was identified (p = 0.043). CONCLUSION: Preoperative radiotherapy followed by surgery is a safe and effective treatment of FIGO stage I or II endometrial carcinomas. BT with two uterine tubes seems to be of interest in the contribution of the treatment of the uterus to sterilize the specimen. The analysis of this new prognostic factor remains important to select a population with worst prognosis.

Preoperative radiotherapy in stage I/II endometrial adenocarcinoma.

From 1972 to 1993, 170 patients received preoperative radiotherapy followed, 5-6 weeks later, by total extrafascial hysterectomy with bilateral salpingo-oophorectomy without lymphadenectomy. Eighty-three patients with good prognostic factors (low grade tumour and no cervical involvement) received low dose rate utero vaginal brachytherapy alone before surgery (Group 1). Eighty-seven patients with poor prognostic factors (high grade tumors and/or cervical involvement) received external radiotherapy to 40 Gy and low dose rate brachytherapy before surgery (Group 2). A single vaginal failure was observed (0.6%). The overall pelvic failure rate was 2.3% (four patients) including two cases with pelvic recurrence and metastases. Three of the four pelvic failures occurred in Group 1. Using the 1971 FIGO clinical staging, 5-year disease-free survival was 82% in Stage Ia, 79% in Stage Ib, and 81% in Stage II (P = 0.36). Five-year disease-free survival was 86% in Grade 1, 76% in Grade 2, and 83% in Grade 3 (P = 0.20). Five-year overall survival was 83% in Stage Ia, 79% in Stage Ib, and 83% in Stage II (P = 0.78). Five-year overall survival was 88% in Grade 1, 77% in Grade 2,83% in Grade 3 (P = 0.27). Complications were recorded with the French-Italian syllabus. Grade 2 complications occurred in 12 cases (7%), Grade 3 in five cases (3%). The lack of correlation between classical risk factors (stage, grade) and disease outcome suggests that preoperative radiotherapy strategies should be preferred when such factors can be identified before surgery.

[Chlamydia trachomatis infection: risk factors].

UNLABELLED: Genital Chlamydia Trachomatis (CT) infections are the most common cause of tubal infertility. Its prevalence is variable between the authors, but seems to be more frequent in the young population. OBJECTIVE: Evaluate the CT genital infection rate in a population consulting either in a sexually transmitted disease center (STD) or in a family planning unit (FPU). --Judge the interest of a routine screening, and by which technic. --Estimate the information level of population about STD and their prevention. METHODS: 270 men and 331 women were detected by uretral or endocervix sample with an immunofluorescence method (Syva Microtrack). CT serology were also realised. RESULTS: 18.5% of man samples, 20% of woman samples in the STD center and 17.9% of woman samples in the FPU were positive for CT. There is a strong correlation between CT positivity and cervical discharge or cervicitis (RR = 4.64, p < 0.01). Serology was positive in 45.5%, 32.5% and 21.2% respectively for STD center's men, STD center's women and PFU's women. The correlation between samples and serology was 62%. Positive samples were more frequent in the 15-30 years old population and positive serology in the over 30 years old population (RR = 3.57, p < 0.01). There is a correlation between CT positive samples and nulliparity, multiple sexual partner and history of genital infection. CONCLUSION: The high prevalence of CT genital infection observed in our centers justify a routine screening especially in the young population.

[Intrepretation of elevated transaminase levels in a pregnancy after a liver transplantation].

A young woman became pregnant 36 months after a liver transplant following an episode of fulminant hepatitis A. At 38 weeks gestation, she delivered by cesarean section following an isolated and moderate elevation of her transaminase enzymes, indicating rejection of the graft. This was later confirmed by liver biopsy. Following augmentation of steroid therapy her postnatal progress was good. The infant progressed quite well. This case raises the question of the management of pregnant women following liver transplantation, with elevated transaminase levels.

Detection and identification of human papillomavirus DNA in genital tract by digoxigenin labelling using the polymerase chain reaction method.

We propose here a simple and rapid method of Human Papillomavirus (HPV) detection applied to genital samples. The method consists of a polymerase chain reaction (PCR) of samples using a consensus primer ser (Snijders et al., 1990) with labelling by Dig-dUTP (Digoxigenin deoxyuridine triphosphate) during amplification. Type identification was carried out by hybridization of the labelling PCR product with a panel of different plasmidic HPVs dotted beforehand on nylon membranes. Forty-five genital samples were tested with this method (30 samples with evident signs of HPV infection, and 15 cervical scrapes which had a normal colposcopic examination and no cytologic signs of HPV infection). We found good sensitivity and specificity levels. The labelling method during PCR did not modify the sensitivity of PCR. Forty-five genital samples were analyzed by this technique and compared with the results of dot-blot and two PCR methods using different primers. They showed a good correlation except in four samples (high grade cervical lesions) which seemed to show a partial deletion or rearrangement. Our method, used for the first time in HPV detection, needed just one PCR and one dot-blot, thus saving an important amount of time and also decreasing examination costs.

[Ovarian steroid cell tumors: a bilateral form].

The authors report a case of bilateral ovarian steroid cell tumour, not otherwise specified (as subclassified now by Scully). For two years a 46-year-old woman had androgenic manifestations. Only plasma testosterone level was increased. A hysterectomy with bilateral ovariectomy was performed. The first diagnosis was bilateral Leydig cell tumour, but no Reinke crystal was found. The final diagnosis was steroid cell tumour, not otherwise specified. No significant nuclear atypia or mitotic activity were found and two-year follow-up was favourable. The authors discuss the difficulty to class some ovarian tumours between Leydig cell tumour and steroid cell tumour, not otherwise specified as defined by Scully.
