Daily practice management of septate uterus: reproductive outcome after septoplasty.

Background: Septate uterus is the most common uterine malformation found in women presenting poor reproductive history. Hysteroscopic septoplasty (HS) restores the uterine anatomy in a safe procedure. Objectives: The goal of our study is to determine the reproductive outcomes after HS of symptomatic septate uterus. Materials and Methods: In a retrospective observational single centre study the reproductive outcomes and complications after HS were evaluated in 31 women with symptomatic septate uterus. The patients were separated into two groups according to the symptoms - infertility or recurrent pregnancy loss (RPL). Main outcome measures: were the pregnancy and live birth rate and secondarily the complication rate. Furthermore, the results were analysed depending on the need of assisted reproductive techniques (ART). Results: The treatment has resulted in an overall pregnancy rate of 71% for both groups. The spontaneous pregnancy rate is 45% and 8 pregnancies resulted from ART (26%). The overall first live birth rate is 51.6%. A decrease has been noticed in the miscarriage rate from 95.24% to 24% (p<0.001) in the overall population. Conclusions: In patients with a symptomatic septate uterus hysteroscopic septoplasty is a safe and effective procedure. The favourable results pointing out the benefits of surgery on the reproductive outcomes as well as the relatively simple and safe technique of HS make the intervention attractive.

[Polycystic ovary syndrome : the advantages of multidisciplinary management]. / Le syndrome des ovaires micropolykystiques : l'avantage d'une prise en charge multidisciplinaire.

The polycystic ovary syndrome is one of the most frequent endocrine disorders in women of reproductive age. The first signs and symptoms of the disease may be present as early as puberty. Diagnostic criteria include hyperandrogenism (clinical or biological), ovulatory dysfunction and polycystic ovarian morphology on ultrasound. The consequences of the syndrome are multiple. These consist of fertility issues and metabolic anomalies with increased cardiovascular risk, but also sleep disturbances, increased risk of endometrial hyperplasia and endometrial cancer and a potentially important psychological impact with decreased quality of life. The management of polycystic ovary syndrome is multidisciplinary and treatment is variable, depending on symptoms and the patient's desire for fertility. In all cases, measures aiming to improve the metabolic dysfunction are essential, going from adopting a healthy lifestyle to adequate therapy of each metabolic anomaly.

Le syndrome des ovaires micropolykystiques est une des endocrinopathies les plus fréquentes de la femme en âge de reproduction. Les premiers signes et symptômes peuvent se manifester dès la puberté. Les critères de diagnostic reposent sur une hyperandrogénie (clinique ou biologique), une anovulation chronique et un aspect d'ovaires micropolykystiques à l'échographie. Les conséquences du syndrome sont multiples, essentiellement concernant les troubles de la fertilité et les perturbations métaboliques avec un risque cardio-vasculaire augmenté, mais également des anomalies du sommeil, un risque augmenté d'hyperplasie endométriale et de cancer endométrial et un impact psychologique parfois important avec diminution de la qualité de vie. La prise en charge est multi-disciplinaire et le traitement variable, en fonction des symptômes et des souhaits de fertilité de la patiente. Dans tous les cas, une prise en charge métabolique, avec une hygiène de vie saine et des traitements visant les perturbations métaboliques individuelles, est essentielle.

Use of methotrexate in the treatment of ectopic pregnancies: a retrospective single center study.

INTRODUCTION: The aim of this study was to evaluate the efficacy of methotrexate (MTX) in the treatment of ectopic pregnancies. We identified predictive factors of success or failure and compared our results with previous studies to make recommendations for its use. MATERIAL AND METHODS: A cohort of 61 patients from a single center was retrospectively analyzed. Inclusion criteria were a diagnosis of ectopic pregnancy and treatment with a single-dose injection of MTX. The need to perform surgery despite MTX was defined as treatment failure while needing a second MTX injection was not. RESULTS: In our cohort, MTX demonstrated a success rate of 80%. This rate rose to 84% when patients with human Chorionic Gonadotropin (hCG ) > 5,000 IU/L were excluded. Twenty percent underwent surgery for pain, increased mass size and/or suboptimal hCG kinetics. Low hCG levels on days 0, 4 and 7 as well as the absence of pain, metrorrhagia and hemoperitoneum were predictive of success. MTX was also efficient in the treatment of persisting pregnancies of unknown location (PUL). CONCLUSION: Our results are consistent with previous studies and emphasize the fact that MTX is less effective above a certain level of hCG. We obtained a cut-off value of 2439 IU/L with a sensitivity of 66.7% and a specificity of 93.9%. MTX should not be used when hCG is higher than 5,000 IU/L and laparoscopic surgery should be performed. Our results bring additional data about the efficacy of MTX in the management of persisting pregnancies of unknown location.

Activation of the human immunodeficiency virus long terminal repeat by varicella-zoster virus IE4 protein requires nuclear factor-kappaB and involves both the amino-terminal and the carboxyl-terminal cysteine-rich region.

Varicella-zoster virus open reading frame 4-encoded protein (IE4) possesses transactivating properties for varicella-zoster virus genes as well as for those of heterologous viruses such as the human immunodeficiency virus type 1 (HIV-1). Mechanisms of HIV-1 LTR (long terminal repeat) transactivation were investigated in HeLa cells transiently transfected with an IE4 expression plasmid and a CAT reporter gene under the control of the HIV-1 LTR. These results demonstrated that IE4-mediated transactivation of the HIV-1 LTR in HeLa cells required transcription factor kappaB (NF-kappaB). Using the gel retardation assay, it was shown that transfection of the IE4 expression vector in HeLa cells was not associated with induction of NF-kappaB under the p50.p65 heterodimeric form and that no direct binding of IE4 to the kappaB sites could be detected. Both Western blot and immunofluorescence analyses suggested that the ability of IE4 to activate transcription through kappaB motives was not connected with its capacity to override the inhibitory activities of IkappaB-alpha or p105. Finally, in vitro protein-protein interactions involving IE4 and basal transcription factors such as TATA-binding protein and transcription factor IIB were carried out. A direct interaction between IE4 and TATA-binding protein or transcription factor IIB components of the basal complex of transcription was evidenced, as well as binding to the p50 and p65 NF-kappaB subunits. Mutagenesis analysis of IE4 indicated that the COOH-terminal cysteine-rich and arginine-rich regions (residues 82-182) were critical for transactivation, whereas the first 81 amino acids appeared dispensable. Moreover, the arginine-rich region is required for the in vitro binding activity, whereas the COOH-terminal end did not appear essential.
