Objective: To evaluate and compare the distribution and density of primordial follicles within a whole sheep ovary and to gain insight into how to overcome the impact of natural follicular heterogeneity on the experimental results. Design: Histological study. Setting: Academic research center. Animals: Five- to nine-month-old ewes. Interventions: Freshly sampled whole sheep ovaries were collected and prepared for histological analysis. Main Outcome Measure(s): The follicular densities and distributions were determined for hematoxylin and eosin sections. A mathematical model was derived based on the follicle counts and Monte-Carlo simulations. Results: Heterogeneous distributions and densities of primordial follicles were identified 1) for distinct areas of the same ovarian cortex, 2) between the ovaries of the same animal and 3) across different ewes. A mathematical model based on the analysis of 37,153 primordial follicles from 8 different ovaries facilitated the estimation of the number of cortical biopsies and sections that had to be analyzed to overcome such heterogeneity. Conclusion: The influence of physiological follicular heterogeneity on experimental and clinical results can be overcome when a definite number of cortical pieces and sections are taken into consideration.

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to analyze the histomorphometric properties of the vaginal wall in women with pelvic organ prolapse (POP). METHODS: In 15 women undergoing surgery for POP, full-thickness biopsies were collected at two different sites of location from the anterior and/or posterior vaginal wall. Properties of the precervical area (POP-Q point C/D) were compared with the most distal portion of the vaginal wall (POP-Q point Ba/Bp) using histological staining and immunohistochemistry. The densities of total collagen fibers, elastic fibers, smooth muscle cells, and blood vessels were determined by combining high-resolution virtual imaging and computer-assisted digital image analysis. RESULTS: The mean elastin density was significantly decreased in the lamina propria and muscularis layer of the vaginal wall from the most distal portion of the prolapsed vaginal wall compared with the precervical area. This difference was statistically significant in the lamina propria for both anterior (8.4 +/- 1.2 and 12.1 +/- 2.0, p = 0.048) and posterior (6.8 +/- 0.5 and 10.1 +/- 1.4, p = 0.040) locations, and in the muscularis for the anterior (5.2 +/- 0.4 and 8.4 +/- 1.2, p = 0.009) vaginal wall. There were no statistically significant differences in the mean densities of collagen fibers, smooth muscle cells or blood vessels between the two locations. CONCLUSIONS: In this study, we observed changes in elastin density in two different locations of the vaginal wall from women with POP. The histomorphometric properties of the vaginal wall can be variable from one place to another in the same patient. This result supports the existence of most vulnerable locations within the vaginal wall and the potential benefit of site-specific prolapse surgery. [less ▲]

Ulipristal acetate (Esmya®) : a selective modulator of progesterone receptors, new treatment of uterine fibromatosis Summary : Uterine fibromatosis is a frequent benign gynaecological disease causing heavy menstrual bleeding and in some cases anaemia. Until now, medical treatment aimed to obtain amenorrhea by administration of progestins or Gn-RH agonists. By inducing hypo-oestrogenism, a reduction of myoma size is observed with Gn-RH agonists but after cessation of the treatment, initial myoma size is noted. The impact of progesterone in myoma growth is nowadays demonstrated and use of selective modulators of progesterone receptors represents a new medical approach of this disease. [less ▲]

BACKGROUND: This study aimed to assess the interest in robot-assisted laparoscopy for deep infiltrating endometriosis and to investigate the perioperative results. METHODS: From November 2008 to April 2012, 164 women with stage 4 endometriosis who underwent robot-assisted laparoscopy (da Vinci Intuitive Surgical System) were included by to eight international participating clinical centers. This study evaluated the procedures performed, the duration of the intervention, the complications, the recurrence, and the impact on fertility. RESULTS: The average operative time was 180 min. The main complications were laparotomy (n = 1, 0.6 %), sutured bowel injury (n = 2, 1.2 %), transfusion for a 2,300-ml bleed (n = 1), prolonged urinary catheterization (n = 1, 0.6 %), ureter-bladder anastomotic leak (n = 1, 0.6 %), and ureteral fistula after ureterolysis (n = 2, 1.2 %). The reoperation rate was 1.8 % (n = 3). The mean follow-up period was 10.2 months. A full recovery was experienced by 86.7 % (98/113) of the patients. After surgery, 41.2 % (42/102) of the patients had a desire for pregnancy, and 28.2 % (11/39) of them became pregnant. CONCLUSION: This study analyzed the largest series of robot-assisted laparoscopies for deep infiltrating endometriosis published in the literature. No increase in surgical time, blood loss, or intra- or postoperative complications was observed. The interest in robot-assisted laparoscopy for deep infiltrating endometriosis seems to be promising.

INTRODUCTION AND HYPOTHESIS: The pathophysiology of pelvic organ prolapse (POP) is incompletely understood. The purpose of this study is to describe the current knowledge about histology of the vaginal wall and its possible involvement in the pathogenesis of pelvic organ prolapse. METHODS: Eligible studies were selected through a MEDLINE search covering January 1986 to December 2012. The research was limited to English-language publications. RESULTS: Investigations of changes in the vaginal tissue that occur in women with genital prolapse are currently still limited and produced contrary results. The heterogeneity of the patients and the control groups in terms of age, parity and hormonal status, of the localization of biopsies and the histological methods as well as the lack of validation of the quantification procedures do not allow clear and definitive conclusions to be drawn. CONCLUSIONS: This review shows that current knowledge of the histological changes observed in women with POP are inconclusive and relatively limited. More studies are needed in this specific field to better understand the mechanisms that lead to POP. [less ▲]

Unexpected finding or persistence of low human chorionic gonadotropin (hCG) levels is not a rare situation. It requires a clinico-biological approach in order to avoid misunderstandings that could lead to inappropriate diagnostic or therapeutic attitudes. Beyond pregnancy, persistent low levels of hCG may be associated with various benign and malignant conditions, i.e. quiescent gestational trophoblastic disease (QTD), raised pituitary hCG or false positive elevation caused by circulating heterophile antibodies. We report the cases of two non-pregnant patients with low serum hCG. In the first case, hCG levels raised during several years following a spontaneous abortion. The likelihood of heterophilic antibodies interference was ruled out and extensive clinical investigation excluded the presence of a tumour. The diagnosis was QTD. In the second case, elevated hCG came to light as an incidental finding in a women with chronic renal failure and led the clinicians to question the laboratory. The cause was probably an increase in pituitary hCG consecutive to terminal renal failure. These cases illustrate the importance of understanding the biology of the hCG and the causes of its persistent low elevation, which are reviewed in this article. It is essential to demonstrate clinically the presence of a tumour in order to avoid unnecessary and ineffective chemotherapy and/or hysterectomy. [less ▲]

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 ▲]
