PURPOSE: The human leucocyte antigen-G (HLA-G) 14-bp insertion/deletion polymorphism was implicated in recurrent implantation failure (RIF), but individual published studies showed inconclusive results. Thus, a meta-analysis was performed to clarify the effect of HLA-G 14-bp polymorphism on RIF risk. METHODS: A comprehensive search for relevant articles was conducted. The odds ratios (ORs) and 95% confidence intervals (CIs) for HLA-G 14-bp polymorphism and RIF were calculated...

AIMS AND OBJECTIVES: to determine the prevalence and pattern of use of peripheral intravenous cannula (PIVC) in hospital wards. BACKGROUND: PIVC are commonly used in acute health care to directly access the bloodstream for the administration of medications, intravenous fluids (IVF) and blood products. PIVC are associated with multiple adverse events including hospital acquired bloodstream infection, thrombophlebitis, and pain/discomfort. Administration of IVF is associated with impaired mobility and nocturia which may increase falls risk in the elderly...

We report a case of ureteric injury during transvaginal oocyte retrieval (TVOR), which was identified immediately (on the operation table) and managed successfully in the same sitting. A 28-year-old woman with primary infertility underwent in-vitro fertilisation (IVF) in a private centre. Because of the policy of doing an ultrasonography post-procedure, she was diagnosed immediately with vaginal vault haematoma and ureteric injury. A double-J catheter was inserted under cystoscopic guidance. A major complication was averted by the timely diagnosis of ureteric injury and its appropriate management...

BACKGROUND: Twin pregnancies are at higher risks of velamentous cord insertion and vasa previa. In vitro fertilization is an additional risk factor of abnormal cord insertion and thus the incidence of vasa previa is likely to increase over the next decades. OBJECTIVE: We sought to evaluate the role of ultrasound imaging in optimizing the management of twins diagnosed with vasa previa antenatally. STUDY DESIGN: We searched our database for twin pregnancies diagnosed with vasa previa and managed antenatally using measurements of cervical length and performed a systematic review of articles that correlated prenatal diagnosis of vasa previa in twins and pregnancy outcome...

Transgenic pigs have become an attractive research model in the field of translational research, regenerative medicine, and stem cell therapy due to their anatomic, genetic and physiological similarities with humans. The development of fluorescent proteins as molecular tags has allowed investigators to track cell migration and engraftment levels after transplantation. Here we describe the development of two transgenic pig models via SCNT expressing a fusion protein composed of eGFP and porcine Histone 2B (pH2B)...

BACKGROUND: Implantation failure of blastocyst is one of the main reasons of failure to become pregnancy following use of Assisted Reproductive Techniques. HLA-G, one of the non-classic HLA subtypes, seems to have a vital role in neutralizing of mother immune system. According to importance of ins/del polymorphism of HLA-G in regulation of HLA-G expression, it seems that this polymorphism has an important effect in immune response against embryo, and so success of embryo implantation...

REVIEW
S D'Arpe, S Franceschetti, J Caccetta, D Pietrangeli, L Muzii, P B Panici
Hydrosalpinx has a detrimental effect on the outcome of in vitro fertilization (IVF). Surgical intervention such as salpingectomy or tubal occlusion before IVF improves the outcome of IVF, but these procedures are often contraindicated in women with dense pelvic adhesions. Thus, it is worthwhile to search minimally invasive alternative therapies. The main objective of this review is to assess and compare the value of all the therapeutic options for hydrosalpinx before IVF. The results of the following procedures were compared: the laparoscopic treatments (salpingectomy/proximal tubal occlusion), the hysteroscopic insertion of device achieving tubal occlusion, the tuberous sclerosis and the aspiration of hydrosalpingeal fluid at the time of IVF procedure...

BACKGROUND: Administration of exogenous progesterone for luteal phase support has become a standard of practice. Intramuscular (IM) injections of progesterone in oil (PIO) and vaginal administration of progesterone are the primary routes of administration. This report describes the administration preferences expressed by women with infertility that were given progesterone vaginal insert (PVI) or progesterone in oil injections (PIO) for luteal phase support during fresh IVF cycles. METHODS: A questionnaire to assess the tolerability, convenience, and ease of administration of PVI and PIO given for luteal phase support was completed by infertile women diagnosed with PCOS and planning to undergo IVF...

The major rate-limiting step in in vitro fertilization (IVF) success appears to be the implantation of the semi-allogeneic embryo into the maternal endometrium. To determine possible risk factors of recurrent failure of embryos to implant, we investigated immunogenetic determinants as level of human leukocyte antigen (HLA) histocompatibility, frequency of killer-cell immunoglobulin-like receptors (KIR) and HLA-C alleles and HLA-G polymorphism. We DNA typed women with recurrent implantation failure (RIF) and their partners for classical HLA Class I, HLA Class II, HLA-G and KIR alleles and compared these results with couples with successful embryo implantation after their first IVF and normal fertile couples...

We present two cases of endometrioid adenocarcinoma grade I, FIGO IA (staging according to the International Federation of Gynecology and Obstetrics) in young women, diagnosed within endometrial polyps. Both patients underwent repeated hysteroscopies and multiple biopsies after initial treatment to medroxyprogesterone one 400 mg daily or the insertion of IUD-LND (intrauterine device-levonorgestrel) for three months. In both of them, all histological samples were negative. Both of them decided that they would try to conceive...

Velamentous and furcate cord insertion with concomitant placenta accreta is a very rare and life-threatening event of pregnancy for both the mother and the fetus. Obstetricians should be cautious about umbilical cord insertion and placental adherence abnormalities in pregnancies conceived by assisted reproductive technologies (ART) particularly in women with Müllerian anomalies.

A successful pregnancy is the greatest goal for reproductive medicine. The probability that pregnancy occurs during a cycle of assisted reproduction is a function of multiple factors, of which embryo transfer is one of the most critical steps in these treatments. This article reports a case of successful pregnancy and twin delivery by transmyometrial embryo transfer after IVF in a woman with a neocavity parallel to the uterine cavity, which prevented the transfer of embryos to the correct place. The patient first went to another fertility centre where embryo transfer was impossible to perform because the cervix could not be canalized...

Posterior lateral endoscopic nucleotomy is widely accepted as a minimally invasive surgery for lumbar disc herniation, but few studies have compared the transforaminal approach using two different techniques, YESS and TESSYS. One hundred and fifty lumbar IVFs of cadaveric spines were studied. Eighteen-gauge needles were inserted percutaneously toward IVFs into the discs by either YESS or TESSYS. The distances from the needle to the nerve root and from the needle to the spinal dura were measured and compared across different spinal segments...
