Association between follicular fluid leptin and serum insulin levels in nonoverweight women with polycystic ovary syndrome.

Aims: We evaluated the links between leptin and visfatin levels and fertilization rates in nonoverweight (NOW) women with PCOS (NOW-PCOS) from Apulia undergoing in vitro fertilization/embryo transfer (IVF).

Materials And Methodology: We recruited 16 NOW women with PCOS (NOW-PCOS) and 10 normally ovulating NOW women (control-NOW). All women underwent IVF.

Increased nuchal translucency and short femur length as possible early signs of osteogenesis imperfecta type III.

Objective: this paper reports an association between an increased Nuchal Translucency (NT) and Osteogenesis Imperfecta (OI), a type of skeletal dysplasia. Measurement of fetal NT at 10-14 weeks of gestation is a sensitive and effective screening method for chromosomal abnormalities.

Methods: a 35-year- old Caucasian woman in her fourth pregnancy was referred to our clinic for an ultrasound scan at 12 weeks of gestation, that confirmed increased Nuchal Translucency.

GnRH agonist versus GnRH antagonist in in vitro fertilization and embryo transfer (IVF/ET).

Several protocols are actually available for in Vitro Fertilization and Embryo Transfer. The review summarizes the main differences and the clinic characteristics of the protocols in use with GnRH agonists and GnRH antagonists by emphasizing the major outcomes and hormonal changes associated with each protocol. The majority of randomized clinical trials clearly shows that in "in Vitro" Fertilization and Embryo Transfer, the combination of exogenous Gonadotropin plus a Gonadotropin Releasing Hormone (GnRH) agonist, which is able to suppress pituitary FSH and LH secretion, is associated with increased pregnancy rate as compared with the use of gonadotropins without a GnRH agonist.

Anti-laminin-1 antibodies in sera and follicular fluid of women with endometriosis undergoing in vitro fertilization.

There is increasing evidence that autoimmune phenomena, including auto-antibody production, may affect fertility in women with endometriosis. The aims of this study are to evaluate anti-laminin-1 antibody (aLN-1) presence in sera and in follicular fluids (FF) of women with endometriosis undergoing IVF and its impact on oocyte maturation and IVF outcome. aLN-1 were measured by a home-made enzyme linked immunosorbent assay in sera and FF obtained from 35 infertile women with endometriosis and in sera from 50 fertile controls and 27 infertile women without endometriosis (IWWE).

Oocyte morphological abnormalities in overweight women undergoing in vitro fertilization cycles.

The effect of elevated body mass index (BMI) on the oocyte quality was investigated in women undergoing in vitro fertilization (IVF) cycles. A total of 268 patients classified on the basis of BMI subject to the first reproductive treatment were included in this study: the normal weight (NW) group consisted of 160 patients with BMI 19-24.9 kg/m(2) and the overweight (OW) group consisted of 108 patients with BMI ≥ 25 kg/m(2).

Apoptosis in normal ovaries of women with and without endometriosis.

The aim of this study was to evaluate the factors predisposing to implants of endometriotic lesions in normal ovarian cortexes of women with and without endometriosis by assessing the expression of pro-apoptotic and anti-apoptotic factors and follicular density. Ovarian biopsies were performed during laparoscopy in 18 patients with endometrioma and in 10 healthy women. Detection of apoptosis was performed with terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling assay.

Follicular growth and oocyte maturation in GnRH agonist and antagonist protocols for in vitro fertilisation and embryo transfer.

Background: The aim of this study was to evaluate the response to treatment in a group of patients undergoing IVF and randomised to receive GnRH-antagonist or the GnRH-agonist. The endpoints were the pattern of follicular growth, the maturity of the oocytes collected, the embryo quality and the pregnancy outcome.

Methods: A total of 136 patients undergoing IVF were included.

Resin-based dentin restorative materials under accelerated ageing: bio-functional behavior.

Object: The aim of the present study was the evaluation of the effect of different polishing and finishing procedures on Filtek Z250 FZ ESPE restorative material. Particularly, the consequence of artificial aging (UV-irradiation) on this resin-based dental material was investigated determining also its outcome on cell behavior.

Methods: 96 specimens of restorative material were prepared using a light emitting diode curing unit and randomly divided into four finishing and polishing groups: (I) No treatment (FZ); (II) Identoflex rubbers (ID); (III) Enhance System (EN) and (IV) Sof-Lex Pop-on XT discs (SF).

[Keratoacanthoma centrifugum of Miedzinski and Kozakiewicz].

We describe the case of one patient, 54-year-old male, with a keratoacanthoma centrifugum situated on the right auricular pavilion. The injury begins as a small nodule with a keratotic innermost part that rapidly is excavated, grows centrifugally, appearing as a new lesion, an expansion of the primary one, in the posterior higher region, with the same characteristics. These lesions join and perforate the auricular cartilaginous tissue.
