Antiphospholipid syndrome and recurrent miscarriages.

Sixty percent of recurrent spontaneous abortions are unexplained. Antiphospholipid syndrome is a multisystem disease with the predominant features of venous and arterial thrombosis, recurrent pregnancy loss, foetal death and the presence of antiphospholipid antibodies. Many epidemiological studies focus on antiphospholipid autoantibodies syndrome (APS) as a cause of recurrent spontaneous abortion (RSA). It is found that 7-25% of RSA would have APS as the main risk factor. 'Association not being synonymous with cause', the proportion of abortions due to the APS is difficult to estimate for several reasons: definition of recurrent abortion is variable, the assays for antiphospholipid antibodies are not well standardised, inclusion of patients in the study group according to the antibodies titre is author dependent. Recent studies suggest association of antiphospholipid antibodies syndrome not only with recurrent abortions but also with infertility. New mechanisms are described by which antiphospholipid antibodies could cause placental thrombosis and infarction, acting directly on the surface anticoagulant expressed on trophoblastic cells. Only lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) assays are sufficiently standardised to be usable in routine. Testing for other antiphospholipid antibodies (aPLs) should remain investigational. Several treatments have been proposed: low doses of aspirin, low or immunosuppressive doses of corticosteroids, and preventive or effective dose of heparin, intravenous immunoglobulin.

Theories of endometriosis.

Endometriosis is characterised by the presence of abnormally located tissue resembling the endometrium with glands and stroma. Several hypotheses have attempted to explain the development of such tissue. The oldest theory, that of metaplasia, suggests that under diverse influences coelomic tissue could be transformed into endometrium. The most often cited theory, that of implantation, proposes that the physiological phenomenon of endometrial reflux in the fallopian tubes during menstruation may, in certain conditions, overcome local defense mechanisms, implant, and proliferate. The peritoneal fluid in unaffected women possesses the capacity to prevent endometriotic tissue from becoming established. The reasons for the occurrence of endometriosis and its consequences (pain, sterility, adhesions) are probably numerous and involve the endometrium, the immune system (macrophages, natural killer cells), the peritoneum, and fallopian tubes. The failure to clear the peritoneal cavity of fragments of endometrium could cause a state of local inflammation with hyperactivation of macrophages secreting a variety of different compounds. Some of these compounds may bring about metaplasia of the peritoneum or the development of Mullerian residues.

[Tumor markers and ovarian cysts].

A practical review of tumor markers, particularly CA125 is proposed. The questions are: what is the role of CA125 assay in cancer screening programs, can preoperative CA125 level predict the benign or malignant nature of an adnexal anomaly, can postoperative CA125 predict the quality of surgical resection of cancer of the ovary?

[Imaging of the endometrium].

During genital activity, physiological and pathological modifications can be observed; Pre- and postmenopausal menometror-rhagia are the principle clinical signs of various endometrial pathologies: benign (polyp, atrophy or endometrial hypertrophy), malignant (cervical or endometrial carcinoma) or neighboring pathologies (myometrium or ovary). The value and methods of various imaging techniques (B-mode and Doppler abdominal and endovaginal ultrasonography, hysterosonography, computed tomography, MR imaging and hysteroscopy) are described together with symptomatological features permitting identification of the endometrial pathology.

Positive margins after conization and risk of persistent lesion.

OBJECTIVE: The aim of this study was to investigate a method to reduce the frequency of uterine reoperation with no persistent lesion and to identify factors predictive of persistent or recurrent lesions. MATERIALS AND METHODS: Of 505 conizations performed by the same surgeon, 71 had positive margins (average patient age = 35.7 +/- 7.7 years). The patients underwent either immediate reoperation or monitoring with a Pap smear and colposcopy. RESULTS: Histologic assessment of the cervical cone after conization showed positive margins in 14.1% of cases [endocervical and exocervical margins affected in 50 of 505 (9.9%) and 21 of 505 (4.2%) cases, respectively]. Of 59 of these patients (83.1%) who underwent follow-up monitoring over an average of 35.2 months (range: 2.6-180. 8), 12 patients (average age: 40.8 +/- 6.4 years) underwent immediate hysterectomy and 47 (average age 34.0 +/- 7.4 years) benefited from monitoring first [secondary discovery of 19 persistent lesions within 6 months and 9 recurrences within 18 months on average (range: 8.8-48 months)]. Of the 9 patients with recurrent lesions, 7 underwent reintervention and 2 monitoring. Of the 19 patients with persistent lesions, 18 underwent reintervention and 1 monitoring. Normal histology was observed in 29.4% of patients undergoing secondary reoperation for an abnormal smear compared with 66.7% of patients undergoing immediate reoperation (P = 0.04). Severity of lesion and age of patients could not be used to predict the incidence of a persistent or recurring lesion. Seventy-nine percent of conizations had positive endocervical margins in patients with a recurring or persistent lesion compared with 48% in patients with normal follow-up (P = 0.03). CONCLUSION: Cytology and colposcopy follow-up in cases of positive conization margins may help to establish justification for the choice of reoperation, thereby limiting morbidity following repeated surgery.

Is endometriosis an endometrial disease?

Endometriosis is characterised by the presence of abnormally located tissue resembling the endometrium with glands and stroma. Several hypotheses have attempted to explain the development of such tissue. The most often cited theory, that of implantation, proposes that the physiological phenomenon of endometrial reflux in the fallopian tubes during menstruation may, in certain conditions, overcome local defense mechanisms, implant, and proliferate. The implantation theory does not explain why endometriosis will develop only in approximately 10-15% of women, while the reflux of endometrial tissue via the fallopian tubes during menstruation is a quasi-universal phenomenon. The endometrium of women affected by endometriosis could be abnormal compared with endometrium of healthy women. The abnormal endometrium could be able to protect itself from harmful effects of immune cells by expressing specific antigens, by harbouring a different immune cell population and by synthetizing and secreting immunosuppressive factors. Several others characteristic features of endometrium have been described in women with endometriosis: (1) production of its own estrogens in too heavy amount; (2) aptitude for setting up on peritoneum; (3) tendencies to proliferate and to invade tissue; (4) aggressiveness for the peritoneum; (5) auto-protection from physiological apoptosis; (6) abnormal expression of heat shock proteins; and (7) excessive angiogenesis.

[Endoscopic para-aortic dissection by the extraperitoneal approach: clinical study of 37 patients].

OBJECTIVE: To give the preliminary results of a series of 37 operations for a para-aortic endoscopic curage by the extraperitoneal passage. MATERIAL AND METHODS: Thirty-seven patients, with an average age of 45.8 +/- 12 years, were operated on for cervical cancer, with an average tumor diameter of 4.9 +/- 1 cm. The indications were: the tumor's diameter > or = 4 cm (N = 24), one FIGO stage > or = IIb distal (N = 10), N+ pelvic (N = 3). The irradiation was pelvic (if N-) or abdominopelvic (if N+). RESULTS: The operation lasted 125.3 +/- 36.8 min, and the average number of ganglions removed was 21.2 +/- 10.2. The upper limit of the curage was submesenteric for nine patients and subrenal for 28. The immediate postoperatory complications were: a retroperitoneal hematoma, an acute intestinal occlusion treated by laparotomy, and a ureteral wound on a fixed ganglion, treated by an endoprosthesis. The number of N+ was ten in all, of which three were macroscopic: 0/1 for stage Ib1; 2/12 (16.7%) for Ib2; 4/14 (28.6%) for IIb proximal; 4/10 (40%) for IIb distal or more. There were 6/26 (23.1%) N+ microscopic cases for subrenal curages, versus 1/8 (12.5%) for submesenteric. (Excluding 3 N+ microscopic cases). All were given postoperatory radiotherapy except for one, who had a widened hysterectomy (N-). After an average follow-up of 9.5 +/- 5.9 months, there were two pelvic recurrences and six at a distance (of which four died). We had a lymphocele superinfection at six weeks on the diverticular sigmoiditis. There was an enteritis in a patient who had an abdominal irradiation after a laparotomy for acute occlusion. CONCLUSION: Out of 36 patients having postoperatory radiotherapy, para-aortic extraperitoneal curage diagnosed seven N+ microscopic cases, allowing 26 uniquely pelvic irradiations.

[Prophylactic and therapeutic vaccine therapy in papillomavirus infections].

HPV types are carcinogenic in cervical cancer. This view is supported by epidemiological and biological evidence. Knowledges of HPV gene expression, of natural history of cervical HPV infection and neoplasia and of tumoral antigenic expression have lead to develop two strategies for vaccine development: 1-Prophylactic vaccines of HPV infections. 2-Therapeutic vaccines aimed to control the tumor growth and even to cure the patient. After an update of natural history of cervical HPV infection, the different target of vaccine strategies. The first published trials will be presented.

[The mechanisms of endometriosis].

Endometriosis is characterised by the presence in abnormal situation of a tissue resembling the endometrium with glands and stroma. Several assumptions try to explain the development of this tissue. The oldest, the theory of the metaplasia, suggests that under various influences the coelomic tissues would be transformed into endometrium. Most often agreed, the theory known as the implantation theory, explains why the endometrial cells and fragment desquamated during menstrual period transported through the fallopian tubes into the peritoneal cavity (physiological phenomenon) could under certain conditions implant, proliferate and develop overcoming the local mechanisms of defence. The peritoneal cavity of the normal women have the capacity to prevent the evolution towards endometriosis. The reasons of an evolution towards the endometriosis and its symptoms (pain, sterility, adherences are probably numerous implying the immune system, the endometrium, the macrophages, the cells natural killer, the peritoneum the fallopian tubes. The failure to removes the peritoneal cavity of the fragments would induce an inflammatory local state with hyperactivation of the macrophages which secrete many molecules, of which some could lead the metaplasia of the peritoneum or the development of müllerian residues.

Rejection of stapled prosthetic mesh after laparoscopic sacropexy.

We report the first case of rejection of prosthetic mesh after laparoscopic sacropexy using a Roticulator stapler. The risk of this complication is extremely low if simple precautions are observed. Our experience suggests that the use of staples to attach the mesh to the vaginal apex should be avoided. At the end of the procedure a careful assessment should be made to ensure that the vaginal wall is intact and not penetrated by staples.

[Clinical aspects of primary cancer of the fallopian tube. A retrospective study of 20 cases].

OBJECTIVES: From a review of 20 cases of primary carcinoma of the fallopian tube, we stress the various clinical aspects of the disease and discuss the possibilities of a preoperative diagnosis. MATERIALS AND METHODS: A retrospective study covering the period between 1982 and 1996. An analysis of the different etiological factors mentioned in the literature, of the physical signs and symptoms of the carcinoma, of the patients' age and hormonal status as well as the role of additional investigations was conducted. RESULTS: The average age of the patients was 62.3 years, 90% of the women had reached menopause and 15% were nullipara. A history of salpingitis was noted in 5% of the patients and another 5% had infertility problems. 20% of the patients had suffered from another carcinoma. Metrorrhagia was the most frequent clinical finding revealing the disease (55%) followed by abnormal secretions of blood stained liquid (15%). Hydrops Tubae Profluens was not observed in this series. The main complementary investigations performed were pelvic ultrasound scanning and hysterosalpingography, preoperative diagnosis was possible in 15% of cases; diagnosis was made during the operative procedure in 45% of cases and by pathologic examination in the remaining 40% of patients. CONCLUSION: Primary carcinoma of the fallopian tube is a rare form of cancer of unknown aetiology. Clinical signs are often unrelated and sometimes misleading; however, preoperative diagnosis is possible if one keeps in mind the existence of this carcinoma.

Intravenous nitroglycerin for internal podalic version of the second twin in transverse lie.

OBJECTIVE: To report our experience with high doses (0.1-0.2 mg per 10 kg pregnant weight) of intravenous (IV) nitroglycerin as a uterine relaxing agent for managing internal podalic version of the second twin in transverse lie with unruptured membranes. METHODS: Between August 1994 and December 1997, we managed 22 cases of internal podalic version of the second twin with the administration of high doses of IV nitroglycerin. RESULTS: Twenty internal podalic versions were completed successfully, and two cases failed. One failure was considered not related to IV nitroglycerin because the patient had a panic attack, requiring general anesthesia for sedation. The internal podalic version then succeeded. The patient with true failure of IV nitroglycerin required emergency cesarean because of acute fetal bradycardia and a nonrelaxed uterus. This was the only nontransverse lie, but with a very high face presentation. One internal podalic version was complicated by hemorrhage (2000 mL). CONCLUSION: Intravenous nitroglycerin to induce uterine atonia, with epidural analgesia, avoids general anesthesia and makes internal podalic version easier. In 22 cases (with success in 20) of internal podalic version of the second twin in transverse lie with unruptured membranes, IV nitroglycerin induced transient and prompt uterine relaxation without affecting maternal and fetal outcomes.

Fetal macrosomia: risk factors and outcome. A study of the outcome concerning 100 cases >4500 g.

OBJECTIVE: Because difficult vaginal delivery is more frequent with macrosomic fetuses, some authors recommend routine caesarean section for the delivery of fetuses >4500 g. The purpose of this study was to evaluate the appropriateness of this recommendation, in particular, to analyze maternal and fetal complications according to the mode of delivery. METHOD: Maternal and neonatal records of 100 infants with weights of at least 4500 g were identified retrospectively from January 1991 to December 1996. Outcome variables included the mode of delivery and the incidence of maternal and perinatal complications. RESULTS: The study sample consisted of 100 infant and mother pairs. Macrosomic fetuses represented 0.95% of all deliveries during this period and only ten were >5000 g. Mean birth weight was 4730 g (maximum, 5780 g). Gestational diabetes was present in nineteen patients. Diabetes was present in three patients. A trial of labour was allowed in 87 women, and elective caesarean delivery was performed in thirteen patients. The overall cesarean rate, including elective caesarean delivery and failed trial of labour, was 36%. Of those undergoing a trial of labour, 73% (64/87) delivered vaginally. Shoulder dystocia occurred fourteen times (22% of vaginal deliveries) and it was the most frequent complication in our series. There were five cases of Erb's palsy, one of which was associated with humeral fracture, and four cases of clavicular fracture. By three months of age, all affected infants were without sequelae. There was no related perinatal mortality and only two cases of birth asphyxia. Maternal complications with vaginal delivery of macrosomic infants included a high incidence of lacerations requiring repair (eleven cases). No complications were noticed in the patients who had a caesarean section. CONCLUSION: Vaginal delivery is a reasonable alternative to elective cesarean section for infants with estimated birth weights of less than 5000 g and a trial of labour can be offered. For the fetuses with estimated birth weight >5000 g, an elective caesarean section should be recommended, especially in primiparous women.
