Endometriosis is a chronic disease usually diagnosed at adult age, even the symptoms begin at adolescence. The medical history could help for the diagnosis and could select the patients for medical or surgical treatment. The main criterion is the description of severe dysmenorrhea necessitating the prescription of oral contraceptive pill early after the menarcha. The early diagnosis is a major issue in the evolution of the disease which is caracterized by physical, psyco-social and sexual repercussions. [less ▲]

Mirror syndrome is a rare entity describing the association of foetal hydrops and maternal symptoms as general oedema and excessive weight gain mimicking preec- lampsia. We report the case of a patient who developed symptoms of oedema, weight gain, headache and biological hemodilution associated with foetal hydrops due to a com- plex congenital heart defect. This symptomatology spontane- ously resolved after foetal expulsion. Mirror or Ballantyne’s syndrome needs to be identified on time and well differenti- ated from preeclampsia. Its consequences may involve the maternal and foetal prognosis. [less ▲]

BACKGROUND: Endometrial cells, which are shed by retrograde menstruation, may aberrantly express molecules involved in invasion and migration, leading to endometriosis. The aim of this study was to investigate the expression of the laminin gamma 2 chain (LAMC2) in the tissues of women with and without endometriosis. METHODS: Endometrial biopsy specimens were collected from healthy volunteers and from endometriosis patients. Biopsy specimens from the corresponding endometriotic lesions were also collected. The expression of laminin gamma 2 chain was evaluated by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Endometrial tissue from women with or without endometriosis showed constitutive expression of LAMC2 mRNA throughout the menstrual cycle. A higher mRNA level was observed in ectopic endometrium (Ec) from women with endometriosis compared with eutopic endometrium (Eu) from women with endometriosis. Immunohistochemistry revealed a varied pattern of laminin gamma 2 chain expression, with increased epithelial expression in eutopic endometrium from women with endometriosis compared with those without endometriosis. CONCLUSIONS: The altered expression of laminin gamma 2 chain in eutopic endometrium from women with endometriosis may provide new opportunities for diagnosis and treatment. [less ▲]

Ureteral endometriosis is a rare entity, espe- cially when it occurs in the postmenopausal period. In certain circumstances, this severe disease can cause obstruction, leading to ureterohydronephrosis and, finally, to a progressive and often silent loss of renal function. The symptomatology is variable and non specific, making pre- operative diagnosis difficult. The treatment is mainly surgical. Its aim is the relief of obstruction to preserve the renal function. We report the case of a 39 year old patient, hysterect- omised for endometriosis nine years earlier, who developed a recurrence demonstrated by ureteral endometriosis and revealed by ureterohydronephrosis. Robot-assisted lapa- roscopic ureterolysis allowed a complete resection of the lesion and resolved the obstruction. No recurrence of ure- terohydronephrosis was found at the fifth and ninth postop- erative month ultrasonographic controls. [less ▲]

Adenomyosis is a medical benign condition of the endometrium-myometrium interface that is histopathologically characterized by the presence of ectopic tissue (endometrial glands and stroma) in myometrium. The diagnosis is complicated by the low specificity of its symptoms and the frequent associations with others gynaecologic pathologies. Consequently, paraclinic investigations are essential to make the diagnosis. [less ▲]

Les femmes enceintes sont conscientes que toute forme d’addiction durant leur grossesse peut être préjudiciable à leur enfant. Pourtant, de nombreuses gestantes continuent de fumer, de boire de l’alcool, de consommer des drogues illicites ou d’absorber des médicaments, car ces dépendances sont particulièrement tenaces. Le quatuor de tête en termes de préjudice fœtal est composé du tabac, de l’alcool, de la cocaïne et de l’ecstasy. La période de grossesse est le meilleur moment pour mettre fin à ces addictions. Aussi, est-il indispensable de sensibiliser le grand public, les pouvoirs politiques ainsi que les médecins sur le fait que les assuétudes durant la grossesse représentent une inégalité de santé et d’espérance de vie importante pour l’enfant à naître.

OBJECTIVE: To present our experience in hysteroscopic removal of abnormally invasive placenta (AIP) residuals using bipolar energy. DESIGN: Case series. SETTING: University hospital. POPULATION: Sixteen patients with AIP residuals after 17 pregnancies. METHODS: Cases were identified by ultrasound, treated with hysteroscopic bipolar electrosurgery and oral contraceptives, and followed up by ultrasound or hysteroscopy. Nine subsequent pregnancies were described. MAIN OUTCOME MEASURES AND RESULTS: Complete removal of AIP residuals was achieved by hysteroscopic bipolar electrosurgery in all cases except one. No peroperative complications occurred. AIP residual recurred in one patient after a subsequent pregnancy and was successfully treated using the same procedure. CONCLUSIONS: AIP residual is a rare condition. Management by hysteroscopic resection using bipolar energy is save and feasible. [less ▲]

Menstrual endometrial breakdown induced by estradiol and progesterone withdrawal is regularly attributed to vasospasm of spiral arteries causing ischemia and hypoxia. We investigated whether hypoxia actually occurred in an in vivo model of menstruation. Three complementary approaches were used to look for signs of hypoxia in fragments of human functionalis xenografted to ovariectomized immunodeficient mice bearing pellets-releasing estradiol and progesterone, and then deprived of ovarian steroids. Hormone withdrawal 21 d after grafting induced menstrual breakdown and MMP expression within 4 d. Local partial oxygen pressure (pO2) was measured by electron paramagnetic resonance using implanted lithium phtalocyanine crystals. In mice with hormone maintenance until sacrifice, pO2 was low one week after grafting (14.8+/-3.4 mmHg) but increased twofold from the second week when tissue was largely revascularized. After 3 wk, pO2 was not modified by hormone withdrawal but was slightly increased on hormone reimpregnation 4 d after removal (34.7+/-6.1 mmHg) by comparison with hormone maintenance (27.1+/-8.6 mmHg). These results were confirmed using fluorescence quenching-based OxyLite measurements. In a further search for signs of hypoxia, we did not find significant HIF1-alpha immunostaining, nor pimonidazole adducts after hormone withdrawal. We conclude that hypoxia is not needed to trigger menstrual-like tissue breakdown or repair in human endometrial xenograft.-Coudyzer, P., Lemoine, P., Jordan, B.

Background: Cryopreservation of cortex ovarian tissue before anti-cancer therapy is a promising technique for fertility preservation mainly in children and young women. Ischemia in the early stage after ovarian graft causes massive follicle loss by apoptosis. VEGF111 is a recently described VEGF isoform that does not bind to the extracellular matrix, diffuse extensively and is resistant to proteolysis. These properties confer a significantly higher angiogenic potential to VEGF111 in comparison to the other VEGF isoforms. Methods: We evaluated the morphology of cryopreserved sheep ovarian cortex, grafted in the presence or absence of VEGF111. Ovarian cortex biopsies were embedded in type I collagen with or without VEGF111 addition before transplantation to SCID mice ovaries. Transplants were retrieved 3 days or 3 weeks later. Follicular density, vasculature network, haemoglobin content and cell proliferation were analysed. Results: Addition of VEGF111 increased density of functional capillaries (p=0.01) 3 days after grafting. By double immunostaining of Ki-67 and von Willebrand Factor (vWF) we demonstrated that proliferating endothelial cells were found in 83% of the VEGF111 group when compared to 33% in the control group (p=0.001). This angio-stimulation was associated with a significant enhancement of haemoglobin content (p=0.03). Three weeks after transplantation, the number of primary follicles was significantly higher in VEGF111 grafts (p=0.02). Conclusion: VEGF111 accelerates blood vessels recruitment, functional angiogenesis and improves the viability of ovarian cortex by limiting ischemia and ovarian cortex damage. [less ▲]

BACKGROUND: There is currently no consensus about indications for surgery for infertility associated with colorectal endometriosis. The aim of this study was to evaluate cumulative pregnancy rates (CPRs) after ICSI-IVF cycles in patients with colorectal endometriosis and to identify determinant factors of fertility outcome. METHODS: Prospective longitudinal multicentre study from January 2005 to June 2011. We included 75 patients with colorectal endometriosis and proved infertility without prior surgery for deep infiltrating endometriosis. Univariable analysis was used to identify determinant factors of pregnancy rate. CPR was calculated using cumulative-incidence methods from log-rank test and Kaplan-Meier curves. For multivariable analysis, Cox proportional hazards model was used. RESULTS: For CPR per patient analysis, the total number of cycles was 113 and the median number of cycles per patient was 1 (range: 1-3). In the whole population the CPR per patient after three ICSI-IVF cycles was 68.6%. The CPR for patients with or without associated adenomyosis was 19 and 82.4%, respectively (P= 0.01). In addition, a patient age over 35 years (P= 0.02) and anti-Mullerian hormone serum level under 2 ng/ml (P= 0.02) were associated with a decreased CPR per patient. At multivariable analysis, adenomyosis [HR = 0.34, 95% CI (0.12-0.99), P= 0.49] was associated with a decreased CPR. CONCLUSIONS: Our data confirm that ICSI-IVF offers a high CPR per patient. However, determinant factors of CPR should be taken into account when informing couples of their options. [less ▲]

Abstract Objective: Placenta increta or percreta is an uncommon pathology, sometimes associated with high maternal morbidity. Its prevalence increases proportionally to the number of cesarean sections. This study analyzed the changes of our management strategy to devise treatment guidelines for this uncommon disorder. Materials and methodology: Between 2005 and 2011, 10 cases of placenta increta or percreta were managed at our university hospital maternity department. Results: Among the 10 cases, seven were diagnosed prenatally. Two patients were diagnosed early, at 14 and 17 weeks of gestational age, and their pregnancies were terminated. Five had hysterectomies during the intrapartum period, and despite attempted conservative treatment for the two others, hysterectomy proved necessary 2 months postpartum because of intrauterine infections. Seven of the 10 women had hysterectomies. Conclusion: Prenatal diagnosis of placenta increta or percreta is essential to plan the delivery in a competent tertiary care center. The decision to perform a cesarean hysterectomy or leave the placenta in situ for spontaneous delivery is based on the extent of infiltration, the patient's hemodynamic status, and her desire to remain fertile. The high-risk of infection and severe hemorrhage must not be overlooked should conservative treatment be chosen. This situation requires prolonged close monitoring. [less ▲]
