RESUMO

The tumoral origin and extensive passaging of HeLa cells, a most commonly used cervical epithelial cell line, raise concerns on their suitability to study the cell responses to infection. The present study was designed to isolate primary epithelial cells from human ectocervix explants and characterize their susceptibility to C. trachomatis infection. We achieved a high purity of isolation, assessed by the expression of E-cadherin and cytokeratin 14. The infectious progeny in these primary epithelial cells was lower than in HeLa cells. We showed that the difference in culture medium, and the addition of serum in HeLa cultures, accounted for a large part of these differences. However, all things considered the primary ectocervical epithelial cells remained less permissive than HeLa cells to C. trachomatis serovar L2 or D development. Finally, the basal level of transcription of genes coding for pro-inflammatory cytokines was globally higher in primary epithelial cells than in HeLa cells. Transcription of several pro-inflammatory genes was further induced by infection with C. trachomatis serovar L2 or serovar D. In conclusion, primary epithelial cells have a strong capacity to mount an inflammatory response to Chlamydia infection. Our simplified purification protocol from human explants should facilitate future studies to understand the contribution of this response to limiting the spread of the pathogen to the upper female genital tract.

RESUMO

To assess the impact of a brief training for obstetricians and midwives about screening for domestic violence during pregnancy follow-up and to identify barriers to a routine enquiry. A monocentric quasi-experimental study was performed in an obstetrics department in Paris, France. We asked patients during their pregnancy follow-up to complete a survey describing their demographic characteristics. They were also asked if a health professional had screened them for domestic violence during the current pregnancy. Exclusion criteria were refusal and inability to complete the survey alone. Health professionals attended a brief training about domestic violence. The intervention provided general information about domestic violence to alert health professionals (prevalence, risk factors, consequences on women's health, pregnancy, and children) and guidelines on screening and how to deal with women disclosing domestic violence. They also had to complete a survey about their knowledge and practice concerning domestic violence. Two months later, patients consulting for their pregnancy follow-up completed the same survey. Health professionals were not aware of the study's aim throughout its course. The primary outcome was the rate of patients screened for domestic violence during pregnancy follow-up. The secondary outcome was the identification of barriers to a routine enquiry. Four hundred ninety-five patients completed the first survey (control group): 21 patients (4.8%) had been screened for domestic violence. Twenty-one health professionals attended the intervention. Eight (38.1%) stated that they never screened for domestic violence, and 3 (14.3%) stated that they always did. Three hundred ninety-five patients completed the second survey (experimental group): 17 patients (4.3% vs 4.8%, p = 0.53) stated that they had been screened for domestic violence. The main barriers to screening mentioned by health professionals were the presence of the partner, the lack of awareness of the need to screen, uncomfortable feelings, and the difficulty to identify victims. There was no increased screening for domestic violence during pregnancy follow-up after a brief training of obstetricians and midwives. An early training during medical studies or more extensive training for professionals could be more efficient.

RESUMO

BACKGROUND: Little is known about the molecules that contribute to the growth of epithelial ovarian carcinomas (EOC), which remain the most lethal gynecological cancer in women. The chemokine Fractalkine/CX(3)CL1 has been widely reported to play a biologically relevant role in tumor growth and spread. We report here the first investigation of the expression and role of CX(3)CL1 in EOC. RESULTS: Epithelial cells from the surface of the ovary and the Fallopian tubes and from benign, borderline and malignant tumors all stained positive for CX(3)CL1. In tumor specimens from 54 women who underwent surgical treatment for EOC diagnosis, CX(3)CL1 immunoreactivity was unevenly distributed in epithelial tumor cells, and ranged from strong (33%) to absent (17%). This uneven distribution of CX(3)CL1 did not reflect the morphological heterogeneity of EOC. It was positively correlated with the proliferation index Ki-67 and with GILZ (glucocorticoid-induced leucine zipper), previously identified as an activator of the proliferation of malignant EOC cells. Hierarchical clustering analysis, including age at diagnosis, tumor grade, FIGO stage, Ki-67 index, CX(3)CL1, SDF-1/CXCL12 and GILZ immunostaining scores, distinguished two major clusters corresponding to low and high levels of proliferation and differing in terms of GILZ and CX(3)CL1 expression. GILZ overexpression in the carcinoma-derived BG1 cell line resulted in parallel changes in CX(3)CL1 products. Conversely, CX(3)CL1 promoted through its binding to CX(3)CR1 AKT activation and proliferation in BG1 cells. In a mouse subcutaneous xenograft model, the overexpression of GILZ was associated with higher expression of CX(3)CL1 and faster tumor growth. CONCLUSION: Our findings highlight the previously unappreciated constitutive expression of CX(3)CL1 preceding tumorigenesis in ovarian epithelial cells. Together with GILZ, this chemokine emerges as a regulator of cell proliferation, which may be of potential clinical relevance for the selection of the most appropriate treatment for EOC patients.

RESUMO

Backgroud. Hereditary angioedema (HAE) is characterized by recurrent swelling of the skin, the abdomen (causing severe acute pain), and the airways. A recently discovered type caused by mutations in the factor XII gene (designated as HAE type III) occurs mainly in women. Estrogens may play an important role, but few obstetrical complications have been reported. Case. We report the symptoms and obstetrical complications of women in two families with HAE attributable to the p. Thr328Lys mutation in the F12 gene. Clinical manifestations included acute and severe maternal abdominal pain, with transient ascites, laryngeal edema, and fetal and neonatal deaths. Patients had normal C4 levels and a normal C1 inhibitor gene. Administration of C1-inhibitor concentration twice monthly decreased the attack rate in one mother, and its predelivery administration (1000 U) led to the delivery of healthy girls. Conclusions. Obstetricians and anesthesiologists should be aware of this rare cause of unexplained maternal ascites and in utero or fetal death associated with edema.

RESUMO

PURPOSE OF REVIEW: To review operative procedures, specific risks, complications and evaluation of efficacy of Essure tubal sterilization performed simultaneously with endometrial ablation. RECENT FINDINGS: Dysfunctional uterine bleeding is a significant health problem in premenopausal women. Endometrial ablation is an effective therapeutic option for the management of menorrhagia and an alternative to hysterectomy. Most women undergoing endometrial ablation are of reproductive age, and, because pregnancy after endometrial ablation could be complicated, many of these women require permanent birth control. Since the introduction of Essure tubal sterilization, this permanent contraception method has been widely used and offers an hysteroscopic approach similar to endometrial ablation techniques. Combining these two procedures offers the advantage of performing the two procedures simultaneously, but inherent rules and technical procedures must be followed to avoid any kind of injury such as heat conduction, material injuries, specific complications and specific follow-up. SUMMARY: The combination of safety and efficacy of endometrial ablation and hysteroscopic sterilization makes a compelling argument for their concomitant use.

RESUMO

OBJECTIVE: To describe the long-term outcome of using tension-free vaginal tape (TVT) with and without associated procedures. METHODS: A questionnaire was mailed to a population of 61 women who had undergone TVT surgery more than 6 years ago. Of this population, 41 (80%) had suffered from stress urinary incontinence (SUI). The questionnaire included questions about urinary symptoms, satisfaction and quality of life. The questionnaire was answered by 51 of the 61 women. RESULTS: Mean follow up was 83 months. The women with SUI had a persistent cure rate of 80% with a satisfaction rate of 97%. The cure rate after 6 years was 37% in women with mixed incontinence. Concomitant hysterectomy (relative risks = 0.87) and body mass index (BMI) do not alter the long-term results of TVT procedure. Peroperative bladder injury is not associated with an increased risk of long-term lower urinary tract symptoms (LUTS) or with a decreased satisfaction rate (relative risks = 0.85). CONCLUSIONS: Concomitant hysterectomy, increased BMI and bladder injury do not alter good long-term results of TVT.

RESUMO

A large ovarian cyst was diagnosed at 22 weeks' of gestation in a 32-year-old woman. The ultrasonographic appearance of the ovarian cyst was unusual with multiple mobile, spherical echogenic structures floating in the cystic mass, called intracystic "fat balls." Right adnexectomy was performed by laparotomy at 28 weeks' of gestation, because of rapid growth and overall size exceeding 20 cm. Pathological examination confirmed ovarian cystic teratoma. Usually, dermoid cysts are slow-growing, even in premenopausal women. The exact mechanism related to the fast growth during pregnancy is unknown. It could be related to an unusual pattern of estrogen (E)/P receptors expression in the cystic teratoma. This case shows that a fast-growing, mature ovarian cystic teratoma may occur during pregnancy.

RESUMO

CONTEXT: In human, the chronology of the testicular development has been extensively studied, but the factors implicated in the onset and the regulation of gametogenesis and steroidogenesis remain hardly known. OBJECTIVES: To identify these factors, we developed an organ culture system for human fetal testes recovered during the first trimester (6-12 wk) of gestation. We first aimed at investigating the characteristics of this system by comparing the in vivo and in vitro gametogenesis and steroidogenesis. Second, we used organ culture to investigate the effect on the human testicular functions of retinoic acid (RA), previously described as a regulator of gonadal development in rodents. RESULTS: Organ culture proved to be an efficient tool for studying the early development of the testicular functions. Indeed, this system was able to maintain satisfactory development of the germ cells and Leydig cells in the absence of any added factor. For older fetuses, the number of germ cells decreased in culture and the LH was necessary to maintain the steroidogenic activity. The addition of 10(-6) m RA decreased the total number of germ cells in the fetal testis at all studied stages. This resulted from an increase in apoptosis, which slightly exceeded the increase of proliferation. However, RA had a stimulatory effect on the steroidogenic function for the youngest fetuses over a short period of time by increasing the expression of P450 cholesterol side-chain cleavage, 17 alpha-hydroxylase/C17-20 lyase, and steroidogenic acute regulatory protein. CONCLUSIONS: Thus, RA appears as a potential regulator of both gametogenesis and steroidogenesis in human fetal testis. Our organ culture is an interesting tool for studying the effects of various factors on the development of human fetal testis, in particular the effect of hormone-disrupting chemicals.
