MicroRNA-551b expression profile in low and high-grade cervical intraepithelial neoplasia.

OBJECTIVE: To evaluate the expression of microRNA (miR)-551b in patients with low and high grade cervical intraepithelial neoplasia (CIN) and to find an association with high-risk Human Papillomavirus (HR-HPV) infection-related prognostic biomarkers. PATIENTS AND METHODS: The expression level of miR-551b was determined in 50 paraffin-embedded cervical specimens (10 normal squamous epithelium, 18 condylomas, 8 CIN1, and 14 CIN2-3) using quantitative Real-time polymerase chain reaction (qRT-PCR). χ2-test compared miR-551b expression in different diagnosis groups. An Ordered Logistic Regression and a Probit correlation were made to correlate miR-551b expression levels with the cervical tissue histological findings. The immunohistochemical distribution of p16 and Ki-67 according to histopathological findings was also assessed. RESULTS: The distribution of the miR-551b expression profile was significantly lower in CIN1-3 samples compared to other histological diagnosis groups (condyloma and negative). The expression levels were inversely correlated to the cervical pathological grade, from negative to CIN2-3. A 1% increase in miR-551b expression level produced an increase of 19% to the probability of a minor histological grade diagnosis in a range from negative to CIN2-3 and an increase of 13% to the probability of a negative histological grade diagnosis. Among the cases with miR-551b expression < 0.02 (considered as cut-off value) a significant statistical correlation was found between p16 and Ki-67 expression and the diagnosis of CIN2-3. CONCLUSIONS: Our data showed a significant inverse correlation between miR-551b expression and the histological grading of the lesions, suggesting a tumor suppressive function in the different stages of cervical dysplasia.

The influence of ovulation induction and assisted conception on maternal and perinatal outcomes of twin pregnancies.

OBJECTIVE: To compare obstetrical and neonatal outcomes of twin pregnancies conceived via assisted reproductive technology (ART) with those of naturally conceived ones and to investigate the influence of the ART procedure type on these parameters. PATIENTS AND METHODS: This observational study included 450 ART and 647 spontaneous twin pregnancies delivered over 15 years at a single university-based hospital of Rome, Italy. Logistic and linear regression models adjusted for confounding factors were used to evaluate the effect of ART and the type of assisted conception (IVF/ICSI, ovulation induction ± intrauterine insemination, egg/embryo donation) on maternal and perinatal outcomes. RESULTS: The mean gestational age was significantly lower in pregnancies conceived via ART. The occurrence rates of gestational diabetes, antenatal admission, prophylactic administration of corticosteroid, very preterm delivery and neonatal intensive care unit admission were higher in the ART group. Twin pregnancies achieved via egg/embryo donation had a lower risk of maternal thrombocytopenia and cervical incompetence and were at greater risk of receiving corticosteroid prophylaxis and patent ductus arteriosus than pregnancies obtained by IVF/ICSI. Conception by ovulation induction was associated with reduced risk of hyperemesis gravidarum and longer neonatal hospitalization compared to pregnancies obtained by IVF/ICSI. CONCLUSIONS: Assisted conception was associated with adverse obstetrical outcomes and lower gestational age, but after adjustment for gestational age neonatal immediate outcomes were similar to those observed in the spontaneous group. There were no many important differences in the outcomes of twin pregnancies obtained by a different type of conception.

Combined oral contraceptives: health benefits beyond contraception.

It has been recognized for over 50 years that combined oral contraceptives (COCs) are also capable of offering health benefits beyond contraception through the treatment and prevention of several gynaecological and medical disorders. During the last years a constant attention was given to the adverse effects of COCs, whereas their non-contraceptive benefits were underestimated. To date, most women are still unaware of the therapeutic uses of hormonal contraceptives, while on the contrary there is an extensive and constantly increasing of these non-contraceptive health benefits. This review summarizes the conditions of special interest for physicians, including dysmenorrhoea, menorrhagia, hyperandrogenism (acne, hirsutism, polycystic ovary syndrome), functional ovarian cysts, endometriosis, premenstrual syndrome, myomas, pelvic inflammatory disease, bone mineral density, benign breast disease and endometrial/ovarian and colorectal cancer. The benefits of COCs in rheumatoid arthritis, multiple sclerosis, menstrual migraine and in perimenopause have also been treated for more comprehensive information. Using COCs specifically for non-contraceptive indications is still outside the product licence in the majority of cases. We strongly believe that these aspects are not of minor relevance and they deserve a special consideration by health providers and by the mass media, which have the main responsibility in the diffusion of scientific information. Thus, counseling and education are necessary to help women make well-informed health-care decisions and it is also crucial to increase awareness among general practitioners and gynaecologists.

Celiac disease and endometriosis: an insidious and worrisome association hard to diagnose: a case report.

BACKGROUND: Primary infertility is an unusual presentation of celiac disease (CD). When non-classical symptoms are present, the diagnosis is not easy and it becomes even more difficult when CD is associated with endometriosis, representing a diagnostic challenge for medical practitioners and gynecologists. CASE REPORT: A 34-year-old patient presented to the authors' observation with primary infertility. Formerly she was treated for endometriosis and the diagnosis of CD was delayed. A favorable clinical and serological response following a gluten-free-diet (GFD) was achieved and a successful pregnancy was obtained. DISCUSSION: This case report emphasizes the role of the CD in women's infertility and the possible association between CD and endometriosis. Even if the relationship between these two diseases is still unclear and further studies to address this issue are required, more attention from gynecologists is needed, considering that the later this association is diagnosed, the greater the probability of adverse outcomes of health developing.

Premature ovarian failure in a 17-year-old woman.

INTRODUCTION: Premature ovarian failure (POF) in a healthy adolescent is a rare event. It is diagnosed by the presence of amenorrhea, hypoestrogenism, and elevated follicle-stimulating hormone (FSH) levels before the age of 40. CASE: The patient presented with amenorrhoea at 17 years after identifying a change from her regular to irregular and metrorrhagic cycles. No positive medical history was noted regarding smoking, chemotherapy, radiation or autoimmune diseases and the physical examination was normal. Her family history revealed that both her maternal aunt and grandmother were affected by POF, but the karyotype test was normal and the FMR1 screening premutation test was negative. The patient underwent an ovarian biopsy which revealed the absence of functional follicles. She began a replacement therapy with estroprogestogens and she was informed about the most successful means to start a family, including adoption and oocyte donation. CONCLUSION: POF is a heterogeneous, multifactorial, and poorly understood condition that involves medical concerns, psychological sphere, and sexuality of the affected patients. Management should be directed at symptoms resolution, bone protection, and psychosocial support for women facing this unexpected and devastating diagnosis.

A 29-year-old woman with complex atypical hyperplasia and polycystic ovary syndrome: a challenging issue.

BACKGROUND: The standard treatment for complex atypical hyperplasia is hysterectomy and bilateral salpingo-oophorectomy. Although radical surgery offers high survival prospects, it also eliminates any chance of further fertility, thus in young nulliparous women who wish to preserve their childbearing potential, a conservative progestin therapy is preferable. CASE REPORT: The authors report a case of complex atypical hyperplasia in a 29-year-old nulliparous woman with polycystic ovary syndrome treated with norethisterone acetate in order to preserve her childbearing potential. The specimens sampled during the follow-up demonstrated inactive endometrium with pseudodecidual changes and no ultrasonographic images exhibited abnormal endometrial thickness. CONCLUSION: According to literature and to the authors' experience, they can affirm that progestin treatment is the most reasonable option for young nulliparous women affected by complex atypical hyperplasia who desire to maintain their fertility potential, showing its efficacy also in patients with an associated polycystic ovary syndrome.

Maternal and perinatal outcomes in spontaneous versus assisted conception twin pregnancies.

OBJECTIVE: To compare maternal and perinatal outcomes in twin pregnancies conceived via assisted reproductive techniques (ART) compared with spontaneous twin pregnancies. STUDY DESIGN: This retrospective study examined 345 dichorionic, di-amniotic twin pregnancies (207 conceived spontaneously and 138 conceived via ART), delivered between January 2007 and June 2011 at the San Pietro Fatebenefratelli Hospital, Rome, a tertiary medical centre. Maternal and perinatal outcomes were compared. A multiple logistic regression analysis was performed to calculate risk estimates as odds ratios (OR) adjusted for maternal age, parity and systemic diseases. Patient data were obtained from a computerized database and analyzed using Statistical Package for the Social Sciences Version 17. RESULTS: Gestational age and birth weight were lower in the ART group, and preterm delivery, gestational diabetes and placental abruption were higher in the ART group compared with the spontaneous conception group. The incidence rates of respiratory complications, patent ductus arteriosus and admission to the neonatal intensive care unit were higher among ART newborns. Length of hospital stay for mothers and newborns was longer in the ART group. No differences in mode of delivery, Apgar score at 5min, congenital anomalies, perinatal mortality, and other considered pregnancy and neonatal complications were found between the two groups. Multivariate analysis adjusted for maternal age, parity and systemic diseases revealed that only the rates of placental abruption [OR 7.45, 95% confidence interval (CI) 2.05-26.98] and patent ductus arteriosus (OR 3.39, 95% CI 1.01-11.46) were significantly higher for the ART group. CONCLUSIONS: Twin pregnancies conceived via ART are at greater risk of poorer outcomes than spontaneous twin pregnancies. This may be related to the type of conception and specific negative features of subfertile patients undergoing infertility treatment.

The addition of GnRH antagonists in intrauterine insemination cycles: a pilot study.

AIM: This prospective study was designed to assess whether the use of GnRH antagonists can improve the success rate of controlled ovarian stimulation (COS) in intrauterine insemination (IUI) treatments. PATIENTS AND METHODS: Eighty patients were divided into two groups: GnRH antagonist group (Group A, n=40) and control group (Group B, n=40). Patients in Group B underwent COS with recombinant Follicle Stimulating Hormone (r-FSH, 50-75 IU/d) only, while patients in Group A were administered r-FSH (50-75 IU/d) plus cetrorelix (0.25 mg/d, starting when ≥ 2 follicles ≥ 14 mm were detected on ultrasound scan). In both groups a single insemination was performed 36 hours after human Chorionic Gonadotropin (hCG, 250 mcg) administration. The primary outcome was clinical Pregnancy Rate (PR). Secondary outcomes were ongoing PR, incidence of Premature Luteinization (PL), number of follicles with mean diameter ≥ 16 mm and between 11 and 15 mm on the day of hCG administration, miscarriage rate, cycle cancellation rate, total amount of r-FSH used and duration of treatment. Student's t test and Chi-square test were used (p < .05 statistically significant). RESULTS: A total of 146 cycles were performed (Group A: n=72; Group B: n=74). A trend towards higher PR in Group A was detected, although it was not statistically significant (Clinical PR: 18.05% vs 10.81%). The number of follicles ≥ 16 mm was significantly increased in Group A. The incidence of both premature LH surge and premature luteinization (PL) was significantly higher in Group B. No significant differences were found in the duration of the stimulation protocol, and in the total amount of r-FSH administered. CONCLUSIONS: The addition of GnRH antagonist in COS/IUI protocol significantly increases the number of mature follicles. However, this multifollicular recruitment is not linked to a significantly higher PR.

Heavy metals and placental fetal-maternal barrier: a mini-review on the major concerns.

BACKGROUND: Heavy metals (HMs) are environmental contaminants with toxic properties for wildlife and humans. The placenta is a privileged organ that, along with the fetal membranes and amniotic fluid, enables growth and development of the fetus during the physiological pregnancy. It also acts as a filter reducing the passage of harmful substances, protecting the embryo and then the fetus from exposure to pollutants. The placental barrier is not completely impermeable to the passage of harmful substances; indeed, HMs were detected not only in placental tissues, but also in amniotic fluid and umbilical cord blood. The amniotic fluid can be considered as a valuable marker of prenatal exposure to exogenous factors, and as an indicator of the integrity of placental barrier. The effect of an intrauterine exposure to heavy metals has been amply evaluated during the last decades. Several studies investigated the exposure to HMs in order to evaluate the mechanism of placental transfer and the impact on fetuses and later children's health. In particular,  the early exposure to Pb, Hg, and Cd was correlated to infant health effects, such as neurological, developmental, and endocrine disorders. The aim of this mini-review is to summarise the current state of knowledge about the interaction between HMs and placental barrier, considering possible implications on fetal health.

Endometrial adenocarcinoma in a young woman.

BACKGROUND: Endometrial carcinoma usually occurs in post-menopausal women, but in three to five percent of cases, it affects patients under 40 years of age, who wish to preserve their fertility. Patients with polycystic ovarian syndrome (PCOS) and the features of this syndrome (including obesity, hyperinsulinemia, and hyperandrogenism) are at great risk of developing endometrial carcinoma. CASE REPORT: The authors report a case of endometrial adenocarcinoma at Stage I in a 37-year-old obese woman with PCOS who underwent surgical staging. DISCUSSION: In young women with obesity and PCOS, a periodic evaluation of the endometrium and implementation of risk-reducing measures for the development of endometrial cancer are needed.

An unusual clinical presentation of a pure yolk sac tumor of the ovary: case report.

INTRODUCTION: Yolk sac tumor (YST) of the ovary is a rare neoplasm, which belongs to the group of ovarian germ cell tumors. It most commonly occurs in children and young women and it is characterized by high malignancy given its premature metastasis. An early diagnosis is important but not easy. CASE: An 18-year-old girl came to the authors' observation for amenorrhea lasting approximately 16 weeks. Abdominal examination revealed a painless palpable mass in the right lower abdomen. At admission ultrasonography (US) and magnetic resonance imaging (MRI) showed a complex mass of the right adnexa with a diameter of about 15 cm. The alpha-fetoprotein (AFP) serum level was elevated to 960 UI/ml. Fertility-sparing surgery was undertaken and the histopathology revealed a Stage IA pure YST. Chemotherapy was avoided and an intensive 36 months follow-up was performed without clinical and radiological evidence of recurrence. CONCLUSION: This is the first case report of a pure YST of the ovary presented with amenorrhea. It is also a very interesting case for its Stage IA despite prolonged duration of symptoms and AFP high levels.
