RESUMEN

INTRODUCTION: Lymphocytic choriomeningitis virus (LCMV) uses rodents such as mice and hamsters as its principal reservoir. When women acquire LCMV during pregnancy because of contact with rodents, it can lead to congenital LCMV infection, which is associated with high mortality and morbidity. Although the number of cases reported in the literature is increasing, LCMV is rarely mentioned because a history of exposure to rodents is uncommon and mostly unknown. OBJECTIVES: The main objective of this article was to summarize all morphological, antenatal, and postnatal abnormalities that may suggest a congenital LCMV infection. METHODS: We reviewed PubMed case reports and case series where an antenatal and/or a postnatal description of at least one case of congenital LCMV infection was documented. RESULTS: We found 70 cases of congenital LCMV infection, 68 of which had antenatal or postnatal brain abnormalities, which were mainly chorioretinitis (59/70), hydrocephaly (37/70), microcephaly (22/70), ventriculomegaly (11/70) and periventricular calcifications (11/70). Antenatal and postnatal extracerebral abnormalities were mainly small for gestational age, ascites, cardiomegaly or anemia. Other organ damage was rare, but could include skin abnormalities, hydrops or hepatosplenomegaly. Seventy percent (49/70) of cases had major cerebral abnormalities that could have been detected by antenatal ultrasound examination. Congenital LCMV infection is associated with a significant mortality rate (30%) and survivors often have severe neurologic sequelae. CONCLUSION: LCMV is a rare congenital infection, but awareness of the various prenatal ultrasound morphological abnormalities should be improved, and LCMV should be considered when first-line etiological explorations are negative, especially when the mother's medical history indicates exposure to rodents.

RESUMEN

OBJECTIVE: Erythrocyte allo-immunization's rate has decreased but without adapted treatment the prognosis is still poor. The aim of our study was to evaluate the fetal prognosis, the complication's rate and the risk factors of complications of the intrauterine transfusion. METHODS: Retrospective study about 37 fetus and 86 intrauterine transfusions between 2001 and 2017. Our main criterion in judging was the occurrence of procedure related complications: premature membrane rupture or premature delivery within seven days from the procedure, chorioamnionitis, abnormal fetal heart rate indicating an emergency ceasarean section within the 24hours from the procedure, in utero death or neonatal death related to the procedure. RESULTS: The survival rate was about 88.9% with a severe complication's rate of 5.8% per intrauterine transfusion and 13.5% per pregnancy. Intrauterine transfusions before 18 weeks of pregnancies was a complication risk factor: 50% of complications before 18 weeks vs. 1.3%, P=0.8×10-3. On the contrary, hydrops did not seem to be a complication risk factor (16.7% of complication with hydrops vs. 3.9%, P=0.27). The localisation of the needle insertion, intra-abdominal or placental insertion, had no effect on the fetal prognosis. CONCLUSION: Intrauterine transfusion complications are rare and it enhances the fetal prognosis. However, an early procedure is related to a higher rate of complications.

RESUMEN

INTRODUCTION: The objective was to report on a consecutive series of monochorionic diamniotic pregnancies complicated by selective Intra-Uterine Growth Restriction (sIUGR) and to describe perinatal outcomes based on whether or not there were umbilical Doppler findings, and specifically to study those pregnancies treated by laser. MATERIAL AND METHODS: This was a retrospective cohort study enrolling monochorionic diamniotic pregnancies presenting isolated sIUGR after 16 weeks' gestation (WG). RESULTS: Of the 25 cases of sIUGR, 16 were type I and 9 type II or III. Types II and III occurred earlier than type I (22.3 versus 24.3 WG), were more severe (discordance of 37% versus 23%), and delivered earlier (31.3 versus 33.9 WG). Survival was 12/18 (66.7%) for types II or III versus 32/32 (100%) for type I. Five laser photocoagulation procedures were attempted and allowed the survival of both twins in 2 cases. Overall survival after laser was 6/10 (60%). DISCUSSION: Isolated sIUGR is associated with high perinatal morbidity and mortality. Laser photocoagulation treatment is feasible and may enable survival of both twins in some cases, but may be technically difficult.

RESUMEN

OBJECTIVES: To report preoperative data, surgical characteristics, complications and perinatal outcome of twin-twin transfusion syndrome (TTTS) managed with laser ablation surgery, to analyze predictors of neonatal survival and to compare the 100 most recent cases with the older 100. MATERIALS AND METHODS: Observational cohort moncentric study of 200 cases of TTTS consecutively treated with fetoscopic laser coagulation between January 2004 and December 2014. RESULTS: There were 49 stage I, 88 stage II, 55 stage III and eight stage IV. Median gestation at time of laser was 20.1±3.0 weeks' gestation (WG) whereas median gestation at delivery was 31.6±5.4 WG. Overall perinatal survival rate was 68.0% and 84.0% have one or more surviving twins. Preterm premature rupture of membranes occurred in 39 cases with and the median gestational age for this complication was 28.8±4.6 SA. Predictive factors to have at least one living birth were Quintero stage and gestational age at delivery. In the most recent period, there were significantly more TTTS Quintero stage I treated with laser, more coagulation by the Solomon technique and a larger number of coagulated vessels. CONCLUSION: The neonatal survival of TTTS is improved by fetoscopic laser coagulation, preferely by using Solomon tecnhique. The use of active management of stage I is currently on research.

RESUMEN

OBJECTIVES: Main objective was to compare accuracy of ultrasonography and MRI for antenatal diagnosis of placenta accreta. Secondary objectives were to specify the most common sonographic and RMI signs associated with diagnosis of placenta accreta. MATERIAL AND METHODS: This retrospective study used data collected from all potential cases of placenta accreta (patients with an anterior placenta praevia with history of scarred uterus) admitted from 01/2010 to 12/2014 in a level III maternity unit in Strasbourg, France. High-risk patients beneficiated antenatally from ultrasonography and MRI. Sonographic signs registered were: abnormal placental lacunae, increased vascularity on color Doppler, absence of the retroplacental clear space, interrupted bladder line. MRI signs registered were: abnormal uterine bulging, intraplacental bands of low signal intensity on T2-weighted images, increased vascularity, heterogeneous signal of the placenta on T2-weighed, interrupted bladder line, protrusion of the placenta into the cervix. Diagnosis of placenta accreta was confirmed histologically after hysterectomy or clinically in case of successful conservative treatment. RESULTS: Twenty-two potential cases of placenta accreta were referred to our center and underwent both ultrasonography and MRI. All cases of placenta accreta had a placenta praevia associated with history of scarred uterus. Sensibility and specificity for ultrasonography were, respectively, 0.92 and 0.67, for MRI 0.84 and 0.78 without significant difference (p>0.05). The most relevant signs associated with diagnosis of placenta accreta in ultrasonography were increased vascularity on color Doppler (sensibility 0.85/specificity 0.78), abnormal placental lacunae (sensibility 0.92/specificity 0.55) and loss of retroplacental clear space (sensibility 0.76/specificity 1.0). The most relevant signs in MRI were: abnormal uterine bulging (sensitivity 0.92/specificity 0.89), dark intraplacental bands on T2-weighted images (sensitivity 0.83/specificity 0.80) or placental heterogeneity (sensitivity 0.92/specificity 0.89). Association of two sonographic or MRI signs had the best sensitivity/specificity ratio. DISCUSSION AND CONCLUSION: Ultrasonography and RMI represent two interesting and complementary diagnostic tools for antenatal diagnosis of placenta accreta. Because of its cost and accessibility, ultrasonography remains the first in line to be used for diagnosis. Use of an analytical grid for diagnosis of placenta accreta could be helpful.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of laser treatment for antenatally detected twin anemia-polycythemia sequence (TAPS) compared with intrauterine transfusion or expectant management. METHODS: All monochorionic twin pregnancies with TAPS managed between 2005 and 2013 in two European fetal therapy centers were evaluated. The outcomes of TAPS cases treated primarily with laser surgery were compared with the outcomes of cases managed expectantly or treated with intrauterine transfusion. RESULTS: In this retrospective study 52 cases of TAPS were detected antenatally and were managed with either laser surgery (n=8; 15%) or intrauterine blood transfusion (n=17; 33%) or expectantly (n=27; 52%). Perinatal survival in the laser group was 94% (15/16) vs 85% (29/34) in the intrauterine-transfusion group and 83% (45/54) in the expectant-management group (P=0.30). The rates of severe neonatal morbidity in liveborn neonates in the laser, intrauterine-transfusion and expectant-management groups were 7% (1/15), 38% (12/32) and 24% (12/50), respectively (P=0.17). There was a significant reduction in respiratory distress syndrome in cases treated by laser. No severe postnatal hematological complications were detected in the laser group compared with 72% (23/32) in the intrauterine-transfusion group and 52% (26/50) in the expectant-management group (P<0.01). Median time between diagnosis and birth was 11 weeks in the laser group compared to 5 weeks after intrauterine transfusion and 8 weeks after expectant management (P<0.01). After injection of colored dye no residual anastomoses were found in the laser group. CONCLUSIONS: Laser surgery for TAPS appears to improve perinatal outcome by prolonging pregnancy and reducing respiratory distress syndrome. Larger, adequately controlled studies are needed to reach firm conclusions on the optimal management of TAPS.

RESUMEN

OBJECTIVE: To compare laser data, complications and neonatal outcome in pregnancies that undergo 'early' (≤ 17 weeks' gestation) fetoscopic laser ablation of placental vascular anastomoses for twin-twin transfusion syndrome (TTTS) with those from 'conventional' cases treated after 17 weeks. METHODS: This was a cohort study of data collected prospectively between January 2004 and December 2012. We included monochorionic diamniotic twin pregnancies complicated by TTTS and treated by fetoscopic laser coagulation. Pregnancies were grouped according to laser treatment ≤ 17 gestational weeks or > 17 weeks and obstetric and neonatal outcomes were compared between groups. RESULTS: A total of 178 pregnancies with TTTS underwent laser therapy: 40 at or before 17 weeks and 138 after 17 weeks. There was no statistically significant difference between these two groups with respect to the rate of preterm prelabor rupture of membranes (PPROM), gestational age at PPROM and rate of PPROM occurring in the 7 days following fetoscopic laser coagulation. In the early group, the interval between performing fetoscopic laser coagulation and the time of delivery was significantly longer (104 days vs 74 days, P=0.0002) and the delivery rate within 7 days of laser treatment was significantly lower (2.5% vs 15.9%, P=0.026). There was no significant difference between the two groups with regard to the rates of pregnancy without live birth (15.4% vs 15.4%, P=0.993), with one live birth (84.6% vs 84.6%, P=0.993) and with two live births (64.1% vs 58.1%, P=0.500). CONCLUSION: In the event of early TTTS, fetoscopic laser coagulation is technically feasible before 17 gestational weeks and obstetric and neonatal outcomes are comparable with those in cases of laser treatment performed after 17 weeks.

RESUMEN

OBJECTIVE: To evaluate the prognostic value of the Children's Hospital Of Philadelphia (CHOP) cardiovascular score and the modified myocardial performance index (MPI), in determining the risk of recipient fetal loss in twin-to-twin transfusion syndrome (TTTS). METHODS: This cohort study was based on data collected prospectively from 105 pregnancies complicated by TTTS (Quintero stages I-IV) and treated with laser photocoagulation between May 2008 and February 2013. Fetuses underwent detailed anatomical and Doppler ultrasonography with cardiac assessment as part of routine care. CHOP score and right MPI were calculated and cut-offs selected using receiver-operating characteristics curve analysis. These were compared according to loss of recipient fetus, using univariate and multivariate logistic regression. The correlation between CHOP score, MPI and Quintero stage was determined and we investigated differences in MPI before and after laser coagulation in a cohort of 90 recipient fetuses. RESULTS: Rates of recipient fetal loss were significantly higher when the CHOP score was ≥ 3 (39.5% vs 12.9%, P = 0.002) and when MPI z-score was > 1.645 (34.5% vs 10.6%, P = 0.004). After adjustment for Quintero stage, the risk of recipient fetal loss remained significantly higher when the CHOP score was ≥ 3 (odds ratio, 3.09; 95% CI, 1.035-9.21). There was a positive correlation between CHOP score, MPI and Quintero stage. MPI was significantly lower after compared with before laser coagulation. CONCLUSION: CHOP score and MPI are predictors of recipient fetal loss in TTTS and may be used to supplement Quintero's classification.

RESUMEN

OBJECTIVE: Primary fetal pleural effusions are rare. If severe, thoracoamniotic shunting is needed. Our objective was to study the management and outcomes of pleural effusions in our unit. METHODS: Retrospective analysis of primary fetal hydrothorax between 1991 and 2010. RESULTS: Of 41 cases, 23 (56%) were hydropic, and 27 (66%) required shunting. Overall, 2 (4.8%) were diagnosed with a chromosomal condition and 4 (9.6%) with a congenital condition (3 Noonan syndrome, 1 mild structural cardiac defect). There were 5 terminations of pregnancy (TOP), 3 in utero deaths and 33 liveborn neonates (80%). Intact survival rate was 44% (12/27) among those shunted, 56% (23/41) among all cases and 70% (23/33) among all liveborn neonates. Most (87.5%) neonatal deaths occurred in newborns delivered before 34 weeks of gestation. The survival rate was higher in nonhydropic compared with hydropic fetuses (85% vs 47%). There were no procedure-related fetal losses. One in utero death was complicated by fatal maternal amniotic embolism. CONCLUSION: Fetuses with pleural effusions should undergo expert prenatal workup. Hydropic fetuses and those with massive effusions are candidates for thoracoamniotic shunting.

RESUMEN

OBJECTIVE: To review outcomes following reductions in trichorionic triplet pregnancies at our institution. METHOD: Retrospective analysis of the outcome of trichorionic triamniotic triplets reduced to singletons (group I, n = 44) or twins (group II, n = 136) at 10 and 12 weeks of gestation. RESULTS: Reduction to one or two was based on parent's preference, hence unrelated to any specific obstetrical or maternal issue. Early fetal loss rate (e.g. <24 weeks) was 9.1% in group I versus 5.1% in group II (p = 0.83). In group I, the take-home baby rate was 86.4% versus 91.9% in group II (p = 0.8). In group I, 17.5% of the women gave birth between 33 and 36(+6) weeks of gestation versus 40.6% in group II (p = 0.026). Delivery beyond 37 weeks was 72.5% in group I and 46.9% in group II (p = 0.01). Intrauterine growth restriction rate was 27.0% in group I versus 45.0% in group II (p = 0.049). CONCLUSION: Reduction to one rather than two fetuses led to significantly higher term delivery rate without significant differences in fetal loss rate or take-home baby rate.

RESUMEN

OBJECTIVE: The aim of this study is to evaluate the incidence of elevated middle cerebral artery peak systolic velocity (MCA-PSV) in twin-to-twin transfusion syndrome (TTTS) before and after laser and its predictive value for intrauterine fetal death (IUFD) occurring within 2 to 7 days following laser. METHOD: This is a 5-year retrospective single-center study on 86 consecutive laser procedures for TTTS. MCA-PSV was measured prior to and 48 h following laser. We correlated perioperative MCA-PSV and fetal survival within 7 days following laser. RESULTS: The incidence of elevated MCA-PSV prior to and following laser (NS) was 8.2% to 9.7% (non significant (NS)). There was no correlation between the incidence of an elevated MCA-PSV prior to laser and fetal survival up to 7 days after laser (NS, χ(2) :3.49). In contrast, the presence of an MCA-PSV above 1.5 MoM 48 h following laser in the former donor puts the former donor at a higher risk for IUFD within a week after surgery [odds ratio (OR):3.42 (interval of confidence (IC) 95%:1.9-30.6), χ(2) :8.68, p < 0.003]. CONCLUSION: The occurrence of an elevated MCA-PSV following laser is related to postoperative donor death within 2 to 7 days after laser.

RESUMEN

OBJECTIVES: To report pre- and post-surgical datas of large series of severe twin-to-twin transfusion syndrome (TTTS) managed with laser ablation surgery in our centre, to evaluate the incidence of complications, perinatal outcome and to compare with other cohorts. PATIENTS AND METHODS: Observational study of 100 cases of TTTS consecutively treated with fetoscopic laser coagulation between January 2004 and April 2010 in CMCO-SIHCUS of Schiltigheim. RESULTS: There are nine stage I, 49 stage II, 38 stage III and four stage 4. Median gestation at time of laser is 20.6 weeks (14-29) whereas median gestation at delivery is 32.6 weeks (16.3-39). Overall perinatal survival rate is 68.5% (137 children over 200). Eighty-five percent have one or more surviving twins. The survival rate is the same for donors and for recipients. Preterm premature rupture of the membranes are observed in 17% of cases and the median gestational age for this complication is 30 weeks (20-34). Cerebral abnormalities are present in 7% of newborns. CONCLUSION: Our results for the management of severe TTTS are comparable to the other reported series. There are still many questions remaining concerning the optimal management of TTTS.

RESUMEN

First trimester screening for Down syndrome is yet to become the first intention strategy in France. This screening program at 11-14 weeks of gestation using maternal age, fetal nuchal translucency, maternal serum free beta-human chorionic gonadotropin and pregnancy-associated plasma protein-A has already been validated for a long time by many international studies. It seems to improve detection rate and decrease false positive rates. We report here five years prospective experience.

RESUMEN

We report and analyze four new cases of spontaneous twin anemia-polycythemia sequence (TAPS) and discuss antenatal management by fetoscopic laser coagulation for this uncommon form of chronic intertwin transfusion. The clinical course and placental characteristics of four pairs of monochorionic-diamniotic (MCDA) twins with spontaneous TAPS, of which one was treated with fetoscopic laser surgery, are described. For the three cases that did not undergo intrauterine intervention, serial Doppler measurement revealed a gradual increase in the middle cerebral artery peak systolic velocity (MCA-PSV) in the donor and a concomitant decrease in the recipient. These twins were born at between 32 and 34 weeks' gestation by Cesarean section. At birth, the donor twins were severely anemic and the recipient twins were polycythemic. Placental injection studies revealed a few small arteriovenous (AV) and venoarterial anastomoses. In the fourth case, because of the high suspicion of TAPS on MCA-PSV data at 24 weeks' gestation, fetoscopic laser coagulation of three small AV anastomoses was successfully performed. No hematological abnormalities were detected at birth. TAPS is a newly described form of chronic twin-to-twin transfusion associated with chronic anemia in the donor and polycythemia in the recipient, without twin oligo-polyhydramnios sequence (TOPS). The monitoring of MCDA pregnancies should include measurement of MCA-PSV in both fetuses even in the absence of intertwin discordance in amniotic fluid volume. Early detection of TAPS could indicate fetoscopic laser coagulation of AV anastomoses.

RESUMEN

OBJECTIVES: To evaluate the understanding of health professionals involved in first-trimester ultrasound screening of the ethical stakes involved by addressing three questions regarding: how much these professionals know about Down syndrome screening by nuchal translucency thickness measurement; their personal opinion with respect to this screening test; and their attitude with respect to their patients, in order to answer the question: 'Are ethical principles respected when women are proposed ultrasound screening during the first trimester of pregnancy?' METHODS: We studied the medical population in the east part of France by sending a questionnaire to each of 460 medical correspondents. This questionnaire attempted to evaluate the respondent's level of medical knowledge, their personal opinion with respect to first-trimester screening and their attitude towards their patients. We adapted the three-dimensional diagram designed by Marteau et al. to develop a measure of informed choice regarding screening. Only health professionals who were relatively well informed and adopted an autonomy-oriented approach were considered to be in a position to obtain true consent from their patients, respecting ethical principles in terms of competence and the autonomy of patients. RESULTS: We received 276 (60%) responses to the questionnaire. Only 31.9% of health professionals had an approach that facilitated obtaining true consent from their patients and respected the ethical principles of competence and patient autonomy; 46% were in favor of the screening test and adopted an autonomy-oriented approach but were poorly informed; and 15.4% had a directive-authoritarian approach combined with poor knowledge. Regression analysis showed that two independent factors (speciality (P = 0.031) and location of practice (P = 0.034)) affected the level of medical knowledge, and two independent factors (location of practice (P = 0.034) and the type of medical practice i.e. public or private (P < 0.05)) affected the opinion of health professionals about the screening test. Two independent factors (speciality (P < 0.001) and the age of the health professional (P = 0.02)) affected the attitudes of health professionals towards their patients. CONCLUSION: The answer to the question 'Are ethical principles respected when women are proposed ultrasound screening during the first trimester of pregnancy?' is clearly 'No'. Major effort is required to ensure that the decisions made by patients are based on a possibility of true choice.

RESUMEN

OBJECTIVE: With the increasing number of operative laparoscopies performed for the treatment of deep pelvic endometriosis, technical difficulties and risk of complications inevitably increase. We report our experience using JJ stents, in women treated for deep pelvic endometriosis, with regard to prevention and management of ureteral lesions. DESIGN: Descriptive retrospective analysis between March 2004 and March 2007. SETTING: Department of Obstetrics and Gynaecology, University Hospital, Strasbourg, France. POPULATION AND METHODS: Cases of women who underwent laparoscopic surgery for severe endometriosis and who needed a JJ stent in their management were recorded. Laparoscopic surgery was performed at the Department of Obstetrics and Gynaecology at CMCO-SIHCUS and Hautepierre Hospitals, Strasbourg, which are referral centres in the treatment of deep endometriosis. MAIN OUTCOME MEASURES: To evaluate the contribution of JJ stent in the prevention and management of ureteral lesions from endometriotic origin and/or iatrogenic origin in women treated for deep pelvic endometriosis. RESULTS: A total of 145 women had surgery for deep pelvic endometriosis. Seventeen (11.7%) women had a JJ ureteral stent inserted. In 82.4% of women, the stent was inserted pre- or peroperatively. We noted three ureteral complications, of which only one needed management by laparotomy. CONCLUSIONS: Except in extreme cases, management of ureteral endometriosis should be performed laparoscopically. Ureteral lesions whether iatrogenic, or secondary to endometriotic disease, can be treated by cystoscopy, JJ stent and laparoscopy. The combination of these three elements is the optimal management and is unlikely to cause subsequent complications. Laparotomy and its associated morbidity should be avoided.

RESUMEN

OBJECTIVES: The purpose of this study is to assess the feasibility of foetal nasal bone (NB) measurement during the first trimester of pregnancy, and to examine the contribution of this measurement to the prenatal screening for Down syndrome following the definition of NB threshold using ROC curves in an unselected population. METHODS: This prospective study was carried out at our centre SIHCUS-CMCO (reference centre) from January 2002 to December 2004 on a total of 2,044 pregnant outpatients at gestational weeks 11-14. Only 1260 singleton foetuses were used for statistical analysis. In the 784 other patients, we were unable to obtain a correct image allowing a reproducible measurement. NB was measured during the same session as nuchal translucency (NT) measurement. Ten trained sonographers took part in the study. Correlation index was evaluated to shed light on a link between interest variables and NB. Screening values of NB measurement in T 21 were also calculated with NB measurement according to crown-rump length, and expressed as the best threshold of multiple of the median determined by ROC curve. Screening values of genetic ultrasound were then evaluated by adding NB measurement to maternal age and NT measurement. RESULTS: Two thousand and forty-four patients were included. We indexed 30 cases of T 21, 14 cases of Trisomy 18, 10 cases of Trisomy 13 and 25 cases of other karyotype abnormalities. Feasibility of measurement was 62% of all cases. We observed a significant relation between NB and NT (p = 0.001 ), as well as between NB and crown-rump-length (p < 0.0001 ). However, size of NB was not correlated to maternal ethnic group (p = 0.314). At 0.6 multiple of the median thresholds, screening values of NB measurement in T 21 were: sensibility 32%, false positive rate 10%, positive predictive value 13.6%, and negative predictive value 96.9%. The likelihood ratio for T 21 in case of NB < or = 0.6 multiple of the median was 4.4 (2.0-9.4). Screening values for maternal age and NT measurement were: sensitivity 88%, false positive rate 23%,positive predictive value 9.7%, and negative predictive value 99.6%. Inclusion of NB measurement increased sensitivity to 100%, positive predictive value to 13.6%, and negative predictive value to 100%, and decreased false positive rate to 5%. CONCLUSION: NB measurement seemed to be a great sonographic marker for T 21. However, its low feasibility made it inadequate for routine settings in first trimester T 21 screening in an unselected population. Statistical independence with NT thickness needed to be further evaluated.

RESUMEN

BACKGROUND: The initial manifestation of a lymphoma as an ovarian mass is unusual, with a reportedly poor prognosis. An exploratory laparotomy is often performed as the ovarian tumor can mimic an advanced epithelial carcinoma. The criteria of lymphoma used in the selection of a nonsurgical approach, that is, chemotherapy possibly associated with radiation, are rarely defined. CASE: We report the case of a 36-year-old woman who presented with an ovarian tumor suggestive of advanced carcinoma. After an initial approach including optimal surgery, the diagnosis of large B-cell CD30+ non-Hodgkin malignant lymphoma was established. Complete remission was obtained after a chemotherapy regimen, appropriate to the specific histologic type of the lymphoma. CONCLUSION: The choice treatment of ovarian non-Hodgkin lymphoma (NHL) is chemotherapy. In the presence of an ovarian tumor, the possibility of ovarian NHL must be considered, and its clinical, biological, and/or radiological signs must be actively sought. Controlled biopsies must also be included to avoid mutilating surgery.

RESUMEN

Mifepristone, a derivative of norethindrone, a first generation synthetic progestative, has a very potent antiprogestative activity and to a lesser degree antiandrogenic and antiglucocorticoid activities. This action makes it potentially useful in the treatment of multiple hormone dependent diseases in obstetrics-gynecology as well as in a variety of medical specialties such as neurology, ophthalmology, and oncology. Nevertheless, the label of abortive pill has incited numerous ethical and political debates concerning the permission to market this drug, and this has contributed to the delay in the assessment of the potential indications of mifepristone. Largely under-utilized in practice despite its increasing theoretical benefit, clinical studies should now de conducted. Thus, based on an international review of literature during the last ten years, we have shed light on the present and potential indications of mifepristone in medical practice.
