Women's country of birth and failure to catch up an overdue cervical cancer cytological screening participation during pregnancy in France, an observational study based on survey sources.

BACKGROUND: Cervical cancer is the fourth most common cancer among women worldwide, both for incidence and mortality. Prevention relies on screening with a Pap test to detect precancerous lesions, which can then be treated. Access to this screening is currently both improvable and inequitable. Pregnancy may be an ideal moment for women to catch up on their overdue cervical cancer screening. In the general population, women's risk of not being screened is associated with their place of birth and other social factors; this may be true as well among pregnant women. Our objective was to study the association between women's place of birth and their failure to catch up with this screening during pregnancy. METHODS: The 2016 French National Perinatal Survey included 13,147 women who gave birth after 21 weeks of gestation. The association between their place of birth and failure to catch up on this screening (defined by the absence of a Pap test during pregnancy for women overdue for it) was adjusted for age, parity, education level, health insurance, and when they began prenatal care with logistic regression models. RESULTS: Among the women for whom screening was then recommended, 49% were not up to date at the start of pregnancy, and of these, 53% were not caught up before delivery. After adjustment for other risk factors, maternal place of birth was not associated with a higher risk of failure to catch up with this screening during pregnancy. However, factors identified as associated with this risk included a low education level and late start of prenatal care. CONCLUSION: About half of women overdue for cervical cancer screening did not catch up with it during their pregnancy. Professionals should pay special attention to women with lower education levels and late initiation of prenatal care, who constitute a group at high risk of not catching up on this screening during pregnancy.

Risk factors for placenta accreta spectrum disorders in women with any prior cesarean and a placenta previa or low lying: a prospective population-based study.

This study aimed to identify the risk factors for placenta accreta spectrum (PAS) in women who had at least one previous cesarean delivery and a placenta previa or low-lying. The PACCRETA prospective population-based study took place in 12 regional perinatal networks from 2013 through 2015. All women with one or more prior cesareans and a placenta previa or low lying were included. Placenta accreta spectrum (PAS) was diagnosed at delivery according to standardized clinical and histological criteria. Of the 520,114 deliveries, 396 fulfilled inclusion criteria; 108 were classified with PAS at delivery. Combining the number of prior cesareans and the placental location yielded a rate ranging from 5% for one prior cesarean combined with a posterior low-lying placenta to 63% for three or more prior cesareans combined with placenta previa. The factors independently associated with PAS disorders were BMI ≥ 30, previous uterine surgery, previous postpartum hemorrhage, a higher number of prior cesareans, and a placenta previa. Finally, in this high-risk population, the rate of PAS disorders varies greatly, not only with the number of prior cesareans but also with the exact placental location and some of the women's individual characteristics. Risk stratification is thus possible in this population.

Tranexamic acid for the prevention of blood loss after cesarean among women with twins: a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery randomized clinical trial.

BACKGROUND: Although prophylactic tranexamic acid administration after cesarean delivery resulted in a lower incidence of calculated estimated blood loss of >1000 mL or red cell transfusion by day 2, its failure to reduce the incidence of hemorrhage-related secondary clinical outcomes (TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial) makes its use questionable. The magnitude of its effect may differ in women at higher risk of blood loss, including those with multiple pregnancies. OBJECTIVE: This study aimed to compare the effect of tranexamic acid vs placebo to prevent blood loss after cesarean delivery among women with multiple pregnancies. STUDY DESIGN: This was a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial data, a double-blind, randomized controlled trial from March 2018 to January 2020 in 27 French maternity hospitals, that included 319 women with multiple pregnancies. Women with a cesarean delivery before or during labor at ≥34 weeks of gestation were randomized to receive intravenously 1 g of tranexamic acid (n=160) or placebo (n=159), both with prophylactic uterotonics. The primary outcome was a calculated estimated blood loss of >1000 mL or a red blood cell transfusion by 2 days after delivery. The secondary outcomes included clinical and laboratory blood loss measurements. RESULTS: Of the 4551 women randomized in this trial, 319 had a multiple pregnancy and cesarean delivery, and 298 (93.4%) had primary outcome data available. This outcome occurred in 62 of 147 women (42.2%) in the tranexamic acid group and 67 of 152 (44.1%) receiving placebo (adjusted risk ratio, 0.97; 95% confidence interval, 0.68-1.38; P=.86). No significant between-group differences occurred for any hemorrhage-related clinical outcomes: gravimetrically estimated blood loss, provider-assessed clinically significant hemorrhage, additional uterotonics, postpartum blood transfusion, arterial embolization, and emergency surgery (P>.05 for all comparisons). CONCLUSION: Among women with a multiple pregnancy and cesarean delivery, prophylactic tranexamic acid did not reduce the incidence of any blood loss-related outcomes.

Survival Without Severe Neonatal Morbidity in Very Preterm Twins According to Planned Mode of Delivery.

OBJECTIVE: To assess survival to discharge without severe neonatal morbidity by planned mode of delivery for twins born before 32 weeks of gestation. METHODS: The JUMODA (JUmeaux MODe d'Accouchement) study was a French national prospective, population-based, cohort study of twin deliveries conducted from February 2014 to March 2015. This planned secondary analysis included diamniotic twin pregnancies from 26 0/7 through 31 6/7 weeks of gestation. Exclusion criteria included contraindications to vaginal delivery and situations for which planned cesarean delivery is favored, and neonatal prognosis depends largely on the underlying pathology rather than the planned mode of delivery. The primary outcome was survival to discharge without severe neonatal morbidity (bronchopulmonary dysplasia, grade 3 or grade 4 intraventricular hemorrhage, periventricular leukomalacia, stage 2 or stage 3 necrotizing enterocolitis). The association between planned mode of delivery and primary outcome was assessed by multivariate Poisson regression model. A propensity-score approach with inverse probability of treatment weighting also was performed to control for indication bias. Subgroup analyses according to birth order and sensitivity analyses limited to spontaneous preterm births only were performed. RESULTS: Among 424 very preterm twin pregnancies, 192 (45.3%) had a planned cesarean delivery and 232 (54.7%) had a planned vaginal delivery. Survival to discharge without severe morbidity did not differ in the two groups: 308 of 384 (80.2%) after planned cesarean and 375 of 464 (80.8%) after planned vaginal delivery (crude relative risk 0.99; 95% CI 0.91-1.15; adjusted relative risk 1.02; 95% CI 0.93-1.11). After applying inverse probability of treatment weighting, planned cesarean delivery still was not associated with higher survival to discharge without severe neonatal morbidity than planned vaginal birth (relative risk 1.11; 95% CI 0.84-1.46). Subgroup and sensitivity analyses showed similar results. CONCLUSION: Planned cesarean delivery for very preterm twins is not associated with higher survival to discharge without severe neonatal morbidity than planned vaginal delivery. These results suggest that very preterm delivery should not be considered a per se indication for planned cesarean in twin pregnancies.

Preterm premature rupture of the membranes: Guidelines for clinical practice from the French College of Gynaecologists and Obstetricians (CNGOF).

In France, the frequency of premature rupture of the membranes (PROM) is 2%-3% before 37 weeks' gestation (level of evidence [LE] 2) and less than 1% before 34 weeks (LE2). Preterm delivery and intrauterine infection are the major complications of preterm PROM (PPROM) (LE2). Prolongation of the latency period is beneficial (LE2). Compared with other causes of preterm delivery, PPROM is associated with a clear excess risk of neonatal morbidity and mortality only in cases of intrauterine infection, which is linked to higher rates of in utero fetal death (LE3), early neonatal infection (LE2), and necrotizing enterocolitis (LE2). The diagnosis of PPROM is principally clinical (professional consensus). Tests to detect IGFBP-1 or PAMG-1 are recommended in cases of uncertainty (professional consensus). Hospitalization is recommended for women diagnosed with PPROM (professional consensus). Adequate evidence does not exist to support recommendations for or against initial tocolysis (Grade C). If tocolysis is prescribed, it should not continue longer than 48 h (Grade C). The administration of antenatal corticosteroids is recommended for fetuses with a gestational age less than 34 weeks (Grade A) and magnesium sulfate if delivery is imminent before 32 weeks (Grade A). The prescription of antibiotic prophylaxis at admission is recommended (Grade A) to reduce neonatal and maternal morbidity (LE1). Amoxicillin, third-generation cephalosporins, and erythromycin (professional consensus) can each be used individually or eythromycin and amoxicillin can be combined (professional consensus) for a period of 7 days (Grade C). Nonetheless, it is acceptable to stop antibiotic prophylaxis when the initial vaginal sample is negative (professional consensus). The following are not recommended for antibiotic prophylaxis: amoxicillin-clavulanic acid (professional consensus), aminoglycosides, glycopeptides, first- or second-generation cephalosporins, clindamycin, or metronidazole (professional consensus). Women who are clinically stable after at least 48 h of hospital monitoring can be managed at home (professional consensus). Monitoring should include checking for clinical and laboratory factors suggestive of intrauterine infection (professional consensus). No guidelines can be issued about the frequency of this monitoring (professional consensus). Adequate evidence does not exist to support a recommendation for or against the routine initiation of antibiotic therapy when the monitoring of an asymptomatic woman produces a single isolated positive result (e.g., elevated CRP, or hyperleukocytosis, or a positive vaginal sample) (professional consensus). In cases of intrauterine infection, the immediate intravenous administration (Grade B) of antibiotic therapy combining a beta-lactam with an aminoglycoside (Grade B) and early delivery of the child are both recommended (Grade A). Cesarean delivery of women with intrauterine infections is reserved for the standard obstetric indications (professional consensus). Expectant management is recommended for uncomplicated PROM before 37 weeks (Grade A), even when a sample is positive for Streptococcus B, as long as antibiotic prophylaxis begins at admission (professional consensus). Oxytocin and prostaglandins are two possible options for the induction of labor in women with PPROM (professional consensus).

The perinatal health of immigrant women in France: a nationally representative study.

OBJECTIVES: Despite the healthy migrant effect, immigrants and descendants of immigrants face health challenges and socio-economic difficulties. The objective of this study is to examine the perinatal health of women of migrant origin. METHODS: The nationwide French ELFE (Etude Longitudinale Française Depuis l'Enfance) birth cohort study recruited approximately 18,000 women. We studied pre-pregnancy BMI, gestational diabetes mellitus (GDM), as well as tobacco, and alcohol consumption during pregnancy according to migrant status and region of origin. RESULTS: Women from North Africa and Turkey had a higher risk of pre-pregnancy overweight and GDM, while women from Eastern Europe and Asia had a lower risk of pre-pregnancy overweight and obesity, but a higher risk of GDM compared to non-immigrants. Women from Sub-Saharan Africa had a higher risk of being overweight or obese pre-pregnancy. Compared to non-immigrants, immigrants-but not descendants of immigrants-had lower levels of tobacco smoking, while descendants of immigrants were less likely to drink alcohol during pregnancy. CONCLUSIONS: Pregnant women of migrant origin have particular health needs and should benefit from a medical follow-up which addresses those needs.

Prevention of spontaneous preterm birth: Guidelines for clinical practice from the French College of Gynaecologists and Obstetricians (CNGOF).

In France, 60,000 neonates are born preterm every year (7.4%), half of them after the spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated with decreased prematurity (level of evidence [LE]1). It is therefore recommended (Grade A). Routine screening and treatment of vaginal bacteriosis is not recommended in the general population (Grade A). The only population for which vaginal progesterone is recommended is that comprising asymptomatic women with singleton pregnancies, no history of preterm delivery, and a short cervix at 16-24 weeks of gestation (Grade B). A history-indicated cerclage is not recommended for women with only a history of conization (Grade C), uterine malformation (professional consensus), isolated history of preterm delivery (Grade B), or twin pregnancies for primary (Grade B) or secondary (Grade C) prevention of preterm birth. A history-indicated cerclage is recommended for a singleton pregnancy with a history of at least 3 late miscarriages or preterm deliveries (Grade A). Ultrasound cervical length screening is recommended between 16 and 22 weeks for women with a singleton previously delivered before 34 weeks gestation, so that cerclage can be offered if cervical length <25mm before 24 weeks (Grade C). A cervical pessary is not recommended for the prevention of preterm birth in a general population of asymptomatic women with twin pregnancies (Grade A) or in populations of asymptomatic women with a short cervix (professional consensus). Although the implementation of universal screening by transvaginal ultrasound for cervical length at 18-24 weeks of gestation in women with a singleton gestation and no history of preterm birth can be considered by individual practitioners, this screening cannot be universally recommended. In cases of preterm labor, (i) it is not possible to recommend any one of the several methods (ultrasound of the cervical length, vaginal examination, or fetal fibronectin assay) over any other to predict preterm birth (Grade B); (ii) routine antibiotic therapy is not recommended (Grade A); (iii) prolonged hospitalization (Grade B) and bed rest (Grade C) are not recommended. Compared with placebo, tocolytics are not associated with a reduction in neonatal mortality or morbidity (LE2) and maternal severe adverse effects may occur with all tocolytics (LE4). Atosiban and nifedipine (Grade B), unlike beta-agonists (Grade C), can be used for tocolysis in spontaneous preterm labor without preterm premature rupture of membranes. Maintenance tocolysis is not recommended (Grade B). Antenatal corticosteroid administration is recommended for all women at risk of preterm delivery before 34 weeks of gestation (Grade A). After 34 weeks, the evidence is insufficiently consistent to justify recommending systematic antenatal corticosteroid treatment (Grade B), but a course of this treatment might be indicated in clinical situations associated with high risk of severe respiratory distress syndrome, mainly in case of planned cesarean delivery (Grade C). Repeated courses of antenatal corticosteroids are not recommended (Grade A). Rescue courses are not recommended (Professional consensus). Magnesium sulfate administration is recommended for women at high risk of imminent preterm birth before 32 weeks (Grade A). Cesareans are not recommended for fetuses in vertex presentation (professional consensus). Both planned vaginal and elective cesarean delivery are possible for breech presentations (professional consensus). Delayed cord clamping may be considered if the neonatal or maternal state allows (professional consensus).

Combined first-trimester Down syndrome screening in HIV-infected women.

OBJECTIVE: To determine if human immunodeficiency virus (HIV) infection or antiretroviral therapy interferes with maternal levels of free human ß-chorionic gonadotrophin (hCGß) and pregnancy-associated plasma protein-A (PAPP-A) and whether any such influence alters first-trimester Down syndrome (DS) screening in HIV-infected women. STUDY DESIGN: We performed a multicenter 1:2 matched case-control study comparing 84 HIV-infected women with singleton pregnancies with controls randomly selected among uninfected women, delivered and screened in the same center and matched for maternal age, geographical origin and fetal sex. RESULTS: Groups did not differ significantly in screening results, although case women showed a slightly lower median free hCGß multiple of the median (MoM) (1.11 versus 1.24 MoM, p=0.32) and higher median PAPP-A MoM (1.45 versus 1.32 MoM, p=0.23) than control women. The false-positive rate was similar in the case and control groups (5% versus 6.5%, p=0.5). Biomarker levels did not differ when comparing treated and untreated patients with their respective controls, and with one another. CONCLUSION: First-trimester DS combined screening biomarker levels and calculated risk do not seem to be significantly altered by HIV infection or antiretroviral treatment. This screening strategy appears to be suitable for HIV-infected women.

Comparing genotoxic signatures in cord blood cells from neonates exposed in utero to zidovudine or tenofovir.

OBJECTIVES: Zidovudine and tenofovir are the two main nucleos(t)ide analogs used to prevent mother-to-child transmission of HIV. In vitro, both drugs bind to and integrate into human DNA and inhibit telomerase. The objective of the present study was to assess the genotoxic effects of either zidovudine or tenofovir-based combination therapies on cord blood cells in newborns exposed in utero. DESIGN: We compared the aneuploid rate and the gene expression profiles in cord blood samples from newborns exposed either to zidovudine or tenofovir-based combination therapies during pregnancy and from unexposed controls (n = 8, 9, and 8, respectively). METHODS: The aneuploidy rate was measured on the cord blood T-cell karyotype. Gene expression profiles of cord blood T cells and hematopoietic stem and progenitor cells were determined with microarrays, analyzed in a gene set enrichment analysis and confirmed by real-time quantitative PCRs. RESULTS: Aneuploidy was more frequent in the zidovudine-exposed group (26.3%) than in the tenofovir-exposed group (14.2%) or in controls (13.3%; P < 0.05 for both). The transcription of genes involved in DNA repair, telomere maintenance, nucleotide metabolism, DNA/RNA synthesis, and the cell cycle was deregulated in samples from both the zidovudine and the tenofovir-exposed groups. CONCLUSION: Although tenofovir has a lower clastogenic impact than zidovudine, gene expression profiling showed that both drugs alter the transcription of DNA repair and telomere maintenance genes.

CD4 T cells with effector memory phenotype and function develop in the sterile environment of the fetus.

The T cell compartment is considered to be naïve and dedicated to the development of tolerance during fetal development. We have identified and characterized a population of fetally developed CD4 T cells with an effector memory phenotype (TEM), which are present in cord blood. This population is polyclonal and has phenotypic features similar to those of conventional adult memory T cells, such as CD45RO expression. These cells express low levels of CD25 but are distinct from regulatory T cells because they lack Foxp3 expression. After T cell receptor activation, neonatal TEM cells readily produced tumor necrosis factor-α (TNF-α) and granulocyte-macrophage colony-stimulating factor (GM-CSF). We also detected interferon-γ (IFN-γ)-producing T helper 1 (TH1) cells and interleukin-4 (IL-4)/IL-13-producing TH2-like cells, but not IL-17-producing cells. We used chemokine receptor expression patterns to divide this TEM population into different subsets and identified distinct transcriptional programs using whole-genome microarray analysis. IFN-γ was found in CXCR3(+) TEM cells, whereas IL-4 was found in both CXCR3(+) TEM cells and CCR4(+) TEM cells. CCR6(+) TEM cells displayed a genetic signature that corresponded to TH17 cells but failed to produce IL-17A. However, the TH17 function of TEM cells was observed in the presence of IL-1ß and IL-23. In summary, in the absence of reported pathology or any major infectious history, T cells with a memory-like phenotype develop in an environment thought to be sterile during fetal development and display a large variety of inflammatory effector functions associated with CD4 TH cells at birth.

Safety of protease inhibitors in HIV-infected pregnant women.

The dire conditions of the human immunodeficiency virus/acquired immune deficiency syndrome epidemic and the immense benefits of antiretroviral prophylaxis in prevention of mother-to-child transmission far outweigh the potential for adverse effects and undeniably justify the rapid and widespread use of this therapy, despite incomplete safety data. Highly active antiretroviral therapy has now become standard care, and more than half the validated regimens include protease inhibitors. This paper reviews current knowledge of the safety of these drugs during pregnancy, in terms of maternal and fetal outcomes. Transfer of protease inhibitors across the placenta is known to be minimal, and current data about birth defects and fetal malignancies are reassuring. Maternal liver function and glucose metabolism should be monitored in women treated with protease inhibitor-based regimens, but concerns about the development of maternal resistance, should treatment be discontinued, have been shown to be groundless. Neonates should be screened for hematologic abnormalities, although these are rarely severe or permanent and are not usually related to the protease inhibitor component of the antiretroviral combination. Current findings concerning pre-eclampsia and growth restriction are discordant, and further research is needed to address the question of placental vascular complications. The increased risk of preterm birth attributed to protease inhibitors should be interpreted with caution considering the discrepant results and the multitude of confounding factors often overlooked. Although data are thus far reassuring, further research is needed to shed light on unresolved controversies about the safety of protease inhibitors during pregnancy.

Genotoxic signature in cord blood cells of newborns exposed in utero to a Zidovudine-based antiretroviral combination.

BACKGROUND: The genotoxicity of zidovudine has been established in experimental models. The objective of the study was to identify genotoxicity markers in cord blood cells from newborns exposed in utero to antiretroviral (ARV) combinations containing zidovudine. METHODS: Cells were investigated by karyotyping and gene expression analysis of the CD34(+) hematopoietic stem/progenitor cell (HPC) compartment. RESULTS: Karyotyping of the cord blood cells from 15 ARV-exposed newborns and 12 controls revealed a higher proportion of aneuploid cells in the exposed group (median, 18.8% [interquartile range, 10.0%-26.7%] vs 6.6% [interquartile range, 3.1%-11.7%]; P < .001). All chromosomes were involved, with a random distribution of these alterations. Gene expression profiling of CD34(+) HPCs from 7 ARV-exposed and 6 control newborns revealed that >300 genes were significantly upregulated or downregulated by at least 1.5-fold in the exposed group (P < .05 for all comparisons). Significant alterations of genes involved in cell cycle control, mitotic checkpoints, and DNA repair were identified. Although this study does not allow discrimination between the roles of each of the 3 drugs, both cytogenetic and transcriptional findings are similar to those in cellular experiments that used zidovudine alone. CONCLUSIONS: The cord blood cells, including hematopoietic stem cells, from newborns exposed in utero to a zidovudine-based ARV combination present cytogenetic and transcriptional abnormalities compatible with DNA damage.

Neonatal plasmacytoid dendritic cells (pDCs) display subset variation but can elicit potent anti-viral innate responses.

Neonates are highly susceptible to infectious diseases and defective antiviral pDC immune responses have been proposed to contribute to this phenomenon. Isolated cord blood pDCs innately responded to a variety of TLR7 and TLR9 dependent viruses, including influenza A virus (IAV), human immunodeficiency virus (HIV) or herpes-simplex virus (HSV) by efficiently producing IFN-α, TNF-α as well as chemokines. Interestingly, following activation by CpGA, but not viruses, cord pDCs tend to survive less efficiently. We found that a hallmark of pDCs in neonates is an extended CD2+pDCs compartment compared to adult pDCs without affecting the antiviral IFN-α response. Within CD2+pDCs, we identified a subpopulation expressing CD5 and responsible for IL-12p40 production, however this population is significantly decreased in cord blood compared to adult blood. Therefore, neonatal pDCs clearly display variation in phenotype and subset composition, but without major consequences for their antiviral responses.

Down syndrome maternal serum marker screening after 18 weeks of gestation: a countrywide study.

OBJECTIVE: The objective of the study was to evaluate the efficacy of maternal serum markers in detecting Down syndrome after 18 weeks of gestation in women who book late for maternity care in a large national retrospective study. STUDY DESIGN: During the period 2007-2012, 27,648 women, regardless of maternal age (17.4% were 35 years old and over), were included in a late Down syndrome screening program (18(+0) to 35(+6) weeks) using the maternal serum markers alpha-fetoprotein and human chorionic gonadotrophin-beta. Samples were assayed in a single laboratory. A dataset of median markers previously established in our laboratory was used for risk calculation. The control group consisted of 27,648 women (14(+0) to 17(+6) weeks) randomly selected from the routine database. RESULTS: When the later screening group was compared with the standard second-trimester control group, the median multiples of medians (1.01 vs 0.98 for alpha-fetoprotein, 1.03 vs 0.98 for human chorionic gonadotrophin-beta), median risks (1 of 2414 vs 1 of 2720), false-positive rates (11.1% vs 11.6%), and trisomy 21 detection rates (83.3% vs 85.7%) did not differ significantly. CONCLUSION: Late Down syndrome maternal serum screening is feasible with a good sensitivity/specificity compromise throughout gestation and is of clinical value in late-booking women.

Progestin treatment of atypical hyperplasia and well-differentiated adenocarcinoma of the endometrium to preserve fertility.

AIM: To evaluate the outcome of a cohort of young women treated with progestin for fertility-sparing management of endometrial atypical hyperplasia (AH) and endometrial carcinoma (EC). This retrospective multicentre cohort study included women under the age of 40 years treated conservatively for AH and EC to preserve fertility using progestin for at least 3 months. Four inclusion criteria were defined: (i) the presence of AH or grade 1 EC confirmed by two pathologists (including a reference pathologist); (ii) the use of conservative management for fertility sparing; (iii) adequate radiological examination before conservative management; and (iv) a minimal follow-up time of one year. RESULTS: Twenty-two patients fulfilled the inclusion criteria (8 had EC, and 14 had AH). After progestin treatment, 17 patients responded. Among the 17 patients who experienced remission, three also experienced disease relapse. One patient initially diagnosed with AH experienced progression of her disease to stage IIIA EC. Ten pregnancies were achieved in eight patients. CONCLUSION: Fertility-sparing management using progestin offers the opportunity to fulfil maternal desires in young patients diagnosed with AH and EC. However, progression of the disease is possible and close follow-up is needed.

[Fertility sparing management of endometrial adenocarcinoma and atypical hyperplasia: a literature review]. / Traitement conservateur du cancer et des hyperplasies atypiques de l'endomètre en vue de préserver la fertilité : revue de la littérature.

In endometrial carcinoma (EC) and atypical hyperplasia (AH) diagnosed in childbearing years, the principle of uterine sparing consists in prescription of antigonadotropic treatment to obtain the remission of the endometrial lesion and allow pregnancy, always with a close follow-up looking for progression or persistence of the tumour. Studies evaluating this strategy have suggested the safety of such an approach, but numerous questions remain unanswered, like those concerning the type and the duration of treatment, and the systematic use of Assisted Reproductive Technologies… We performed a critical literature review in order to analyse patients and tumoral characteristics, treatment management and the results of fertility sparing strategy. This review shows that fertility sparing management of AH and intramucous EC permits to obtain pregnancy in one third of candidates. Few disease-related deaths have been reported after this management. One-third of patients experienced progression lesion beyond the endometrium, but generally limited to the myometrium. Progestins have been widely evaluated in this indication and provide an overall remission rate of 80% with a recurrence risk of 25%.

Cervical adenocarcinoma presenting as a cardiac tamponade in a 57-year-old woman: a case report.

INTRODUCTION: Pericardial effusion as a complication of malignant gynecological disorders is rare. Few cases of endometrial cancer, squamous cell carcinoma of the cervix, ovarian cancer and uterine carcinosarcoma have been previously reported. We report the first case of cardiac tamponade secondary to a cervical adenocarcinoma. CASE PRESENTATION: A 54-year-old Caucasian woman, without any relevant medical history and no gynecological aftercare, was admitted to our hospital emergency room with severe dyspnea. Echocardiography revealed severe pericardial effusion with a swinging heart. An emergency pericardial drainage was performed through a pericardial window, which permitted the draining of 700 mL of bloody fluid and a pericardial biopsy. Cytological examination of the fluid revealed atypical cells, and the biopsy specimen showed tumor emboli suggestive of adenocarcinoma. Magnetic resonance imaging showed a 35 mm cervical lesion indicative of an endocervical tumor. Exploratory laparoscopy revealed diffuse peritoneal lesions and histological examination of cervical curettage showed a poorly differentiated micropapillary adenocarcinoma of the cervix. CONCLUSION: Carcinomatous pericarditis as the first symptom of a malignant gynecological adenocarcinoma has not, to the best of our knowledge, been documented before. This case highlights the extreme severity of pericardial effusion secondary to cervical adenocarcinoma, a sign of advanced disease. Gynecological malignancies have to be considered in cases of neoplastic pericardial effusion.

Gigantomastia and vulvar lactating adenoma in a patient with myasthenia during pregnancy.

We report the association of gigantomastia during pregnancy and a lactating adenoma in ectopic breast tissue of the vulva in a context of myasthenia in a 27-year-old primigravid woman. We discuss the pathophysiologic condition and management of gigantomastia that involves ectopic breast tissue during pregnancy.

Glycosidic Tn-based vaccines targeting dermal dendritic cells favor germinal center B-cell development and potent antibody response in the absence of adjuvant.

In vivo targeting of C-type lectin receptors is an effective strategy for increasing antigen uptake and presentation by dendritic cells (DCs). To induce efficient immune response, glycosylated tumor-associated Tn antigens were used to target DCs through binding to macrophage galactose-type lectin (MGL). The capacity of Tn-glycosylated antigens-and the multiple antigenic glycopeptide Tn3 therapeutic candidate vaccine-to target mouse and human MGL(+) DCs are demonstrated, especially regarding dermal DCs. In mice, MGL(+) CD103(-) dermal DCs efficiently captured and processed glycosylated Tn antigen in vivo, inducing a potent major histocompatibility complex (MHC) class II-restricted T-cell response. Intradermal immunization with Tn-glycopeptides induced high levels of Th2 cytokines-even in the presence of unmethylated cytosine-phosphate-guanosine-and was associated with increased expansion of the germinal center B-cell population. Therefore, MGL acts as an efficient endocytic antigen receptor on dermal DCs in vivo, able to prime Tn-specific T- and B-cell responses. Moreover, even in the absence of adjuvant, immunization with this glycosidic Tn-based vaccine induced high levels of anti-Tn antibody responses, recognizing human tumor cells. In vivo DC-targeting strategies, based on Tn-MGL interactions, constitute a promising strategy for enhancing antigen presentation and inducing potent antibody response.
