[Uterine rupture following operative hysteroscopy].

The aim of this study was to attempt to identify factors predictive of uterine rupture following operative hysteroscopy. A MEDLINE and EMBASE search (1980 to April 2006) using the keywords "hysteroscopy", "uterine rupture" and "pregnancy" was performed with no limitations of languages. 18 cases of uterine rupture following operative hysteroscopy were retrieved. Hysteroscopic metroplasty (uterine septa and synechiae) was involved in 16 (89%) cases. Hysteroscopic resection was performed with monopolar current cutting, rigid scissors and laser in respectively 14 (78%), 3 (16.5%) and 1 (5.5%) cases. Uterine perforation occurred in 10 (55.5%) cases. The interval between hysteroscopy and subsequent pregnancies varied from 1 month to 5 years with an average delay of 16 months. Uterine rupture occurred between 19 and 41 weeks, with no labour in 12 (66.5%) cases. Four fetal and one maternal deaths followed uterine rupture. Hysteroscopic metroplasty may expose patients to an increased risk of uterine rupture in subsequent pregnancy. Uterine perforation and/or the use of current monopolar section during operative hysteroscopy increase this risk. Uncomplicated hysteroscopic resection of submucous myomas and endometrial polyps do not alter obstetrical outcome. Considering hysteroscopic metroplasty, the use of coaxial bipolar electrode should be preferred.

[Young women with atypical endometrial hyperplasia or endometrial adenocarcinoma stage I: will conservative treatment allow pregnancy? Results of a French multicentric survey].

OBJECTIVES: To analyse the carcinological and obstetrical results of young women with atypical endometrial hyperplasia or endometrial adenocarcinoma, treated in a conservative way to allow pregnancy. PATIENTS AND METHODS: A retrospective analysis of 13 cases (5 adenocarcinomas and 8 atypical hyperplasias) followed in 8 French centers between 1997 and 2004. RESULTS: After 4.6 months of conservative treatment, there were no residual lesions in 61.5% of the cases. Progestatives seem to be the most effective treatment. Tumoral regression makes it possible to plan a pregnancy, with childbirth in 25% of the cases. In these frequently infertile patients, all the techniques of assisted reproduction can be used. Recurrences are not rare after hormonal treatment (37.5%), so, total hysterectomy is justified after delivery. DISCUSSION AND CONCLUSION: Conservative treatment for young women with atypical endometrial hyperplasia or endometrial adenocarcinoma stage I can be considered in some cases to enable pregnancy.

[Isthmic pregnancy located in a previous caesarean section scar treated with methotrexate. A case report].

We report a case of a patient who presented an isthmic pregnancy successfully treated with an intramuscular injection of methotrexate. The diagnosis of isthmic pregnancy was made clinically (cervical colour was normal, inferior segment soft and enlarged) and echographically (long cervix, foetal sack situated in the isthmus and the uterine body was empty). An isthmic full term pregnancy is possible but would carry major haemorrhagic risk. There are several therapeutic options if the pregnancy is interrupted: medical treatment of methotrexate, curettage, curettage with embolisation of the uterine arteries and as a last resort, hysterectomy. The success of conservative treatment seems to be related to the criteria known for the cervical pregnancy, which are cardiac activity, the level of HCG, gestational age and cranial-caudal length.

[Low-grade endometrial stromal sarcoma: contribution of hormone therapy and etoposide].

Endometrial stromal sarcoma is a rare malignant uterine tumor. We report 4 cases of low-grade endometrial stromal sarcoma, corresponding to the form with a mitotic index at less than 10 mitoses per 10 high power fields (HPF), from which we carried out a review of the literature and defined the potential interest of hormone therapy and chemotherapy by etoposide. Generally diagnosed in pre-menopause, the main clinical signs, which are not very specific, are metrorrhagia and pelvic pain. The etiologic diagnosis is established from the pathology analysis. Intravascular extension, which is observed in nearly 50% of patients, should evoke the disease. The initial treatment is mainly based open surgery, generally total hysterectomy with annexectomy. There is no effective adjuvant treatment. The potential of reccurences remains around 50% with a 34-month median. Several therapeutic options are possible after recurrence but no standard treatment has been established. We are mainly interested in three medical options but the surgery remains an alternative of choice. Chemotherapy by oral etoposide offers easy administration, good compliance and acceptable toxicity with median 20-month remission in 3 patients before progression. Hormone therapy with progestogens (hormone receptor expression of the tumor is 71% for estrogens and 95% for progesterone) is widely studied in the literature with a 46% response rate and 46% rate of disease stabilization. Hormone therapy with an anti-aromatase appears to be a promising treatment according to the bibliographic references on this subject. Overall, prognosis of low-grade endometrial sarcoma is relatively good with 100% survival at 5 years. The progression pattern is slow, requiring regular and prolonged surveillance.

[Maternal obesity: effects on labor and delivery: Excluding other diseases that might modify obstetrical management].

AIMS: The aim of this survey was to analyze the effects on labor, delivery, afterbirth, and neonatal status of maternal obesity, independently of other diseases that might modify obstetrical management. POPULATION AND METHODS: Cross-sectional survey of cases during one year in the obstetrics department of a university hospital center. The inclusion criterion was obesity, defined as BMI > 30. The exclusion criteria were hypertension, pregnancy-related hypoxemia, diabetes (pre-existing or pregnancy-related), maternal cardio-pulmonary disease, uterine scar, multiple pregnancy, and non-cephalic presentation. Two groups, one obese and the other not, were matched for age and parity. RESULTS: The rate of post-term deliveries was higher among obese women (p = 0.04), induction of labor more frequent (p = 0.05), and the duration of its first phase longer (p = 0.003); the cesarean rate was seven times higher (14.6% versus 2.1%) and the mean weight of the newborns significantly higher (p = 0.01). Multivariate analysis found the following factors to be significantly associated with maternal obesity: longer duration of the first phase of labor, less frequent spontaneous vaginal delivery, higher cesarean rate, and higher rate of lack of progress in dilatation. CONCLUSION: This study shows that maternal obesity is a risk factor for complications during pregnancy, independently of its standard complications--pregnancy-related diabetes and hypertension. It compromises the smooth progression of labor and delivery. Pregnancy in obese women must be considered to be "at risk", regardless of any complications of obesity. It is thus important to help obese women become more aware of the importance of a balanced diet for themselves and their children. The presence of an obese adult in the household quadruples the risk of obesity in children.

[Malignant tumors arising in extra-ovarian endometriosis: a case report].

We report a case of degenerative extra-ovarian endometriosis. This is a rare complication of endometriosis, the frequency of which is estimated at 0.9%. In more than 50% of the cases, the diagnosis is made following investigation for abdominal pain. If the degeneration is of the same histological type as the endometriosis, it can be said to have arisen from the endometriosis. First-line treatment is surgery, removing as much endometriosis as possible, staging at this point is also necessary. Second-line treatment, with chemotherapy, radiotherapy and even hormonotherapy may be needed. Prognosis for this tumor is variable, from 10 to 100% five-year survival, depending on histological type and localization of the disease.

[Benzodiazepine poisoning in a neonate: clinical and toxicokinetic evaluation following enterodialysis with activated charcoal].

CASE REPORT: A pregnant woman who was a regular user of anxiolytics was admitted to the maternity ward at 38 weeks and 4 days amenorrhea after a massive overdose of clorazepate dipotassium, a benzodiazepine. The exact quantity ingested was undetermined. The infant, born at 39 weeks, presented no spontaneous breathing and tracheal intubation was necessary in the delivery room. The neonatal blood concentrations of the clorazepate metabolites were very high at delivery (26 mg/l nordiazepam and 3.5 mg/l oxazepam) and showed little change over the next 5 days (16 mg/l nordiazepam and 2.1 mg/l oxazepam, with an apparent half-life of 168 h for nordiazepam and 160 h for oxazepam). By day 6, the infant was still dependent on ventilator support and enterodialysis was begun with repeated doses of activated charcoal (1 g/kg every 6 h by gastric tube). Treatment was continued for 5 days and a spectacular diminution in the serum concentrations of the two metabolites was noted on day 11: 1.5 mg/l nordiazepam and less than 0.1 mg/l oxazepam. The nordiazepam and oxazepam half-lifes were reduced to 42 h and 30 h respectively. The concomitant clinical improvement authorized the weaning from ventilation on day 12. CONCLUSION: This is the first report of the use of enterodialysis to treat severe benzodiazepine poisoning in a neonate. Depuration of the toxin was accelerated and the duration of intensive care was shortened thanks to this technique.

Towards a better understanding of the magnetic interactions within m-phenylene alpha-nitronyl imino nitroxide based biradicals.

An extensive investigation of the magnetic properties of three series of biradicals (bis-nitronyl nitroxides diNN-R, bis-imino nitroxides diIN-R and mixed INNN-R, where R is either hydrogen, a triple bond or trimethylsilylacetylenic group) has been carried out to give clear values of the intramolecular interactions through the m-phenylene coupling unit with alpha-nitronyl nitroxides (NN) or alpha-imino nitroxides (IN). An EPR study of the molecules in the isolated state is validated by ab initio calculations, which show the respective influence of spin polarisation and molecular conformation on the singlet-triplet gaps. All these results indicate that the triplet state is the ground state for such biradicals, except when the imidazolyl cycles are orthogonal to the phenyl ring. The magnetic properties of the biradicals in the solid state can be rationalised by examination of the short contacts produced between the ONCNO and ONCN groups. EPR studies on single crystals of the H-substituted series have confirmed the presence of a structural distortion for diNN-H whereas diIN-H and INNN-H do not exhibit such a peculiarity. The magnetic behaviour of diIN-H is described well by a four-spins model, with a strong intermolecular antiferromagnetic interaction of -90 K, whereas in the case of the two other compounds, a supplementary contact involves more complex interactions between the dimers. The compound diNN-tmsa exhibits a ferromagnetic intermolecular interaction of +11 K within the dimers, and this could be attributed to the relative disposition of the imidazolyl rings. Compound diNN-tr reveals a chain-like behaviour, whereas diIN-tr shows a predominant antiferromagnetic interaction within the dimers. The values for the intramolecular interactions in the solid state are in good agreement with those found for the isolated molecules.

[Gravely ill newborns (excluding greatly premature) in 1986 and 1995 in three deparments of Pays de la Loire].

AIM: Evaluation of the progress in the treatment of seriously ill newborn infants under hospital care over the nine-year period from 1986 to 1995 in three departments of the Pays de la Loire region in France. POPULATION AND METHODS: The category of seriously ill newborn infants included only infants born after at least 32 weeks of gestation and having a Cullen severity score higher than 2. The two groups of seriously ill newborn infants at risk in 1986 and 1995 were first compared to a control group of healthy newborn babies delivered during the same years. The two groups were then compared with each other. RESULTS: In 1986 and 1995, the numbers of births were respectively 32,876 and 29,446, and the numbers of seriously ill newborn infants under hospital care were respectively 307 and 245. However, between 1986 and 1995 the risk factors as well as the causes of morbidity had changed. The average period of hospitalization decreased by five days. The mortality rate dropped from 0.16% to 0.09% (P < 0.05) and the number of serious complications decreased from 0.07% to 0.03% (P < 0.05). CONCLUSION: The improvement in the care of seriously ill newborn infants between the two reference periods, 1986 and 1995, may be attributed not only to technical progress but also to a better organization of the perinatal care in our region.
