Endometriosis allergic or autoimmune disease: pathogenetic aspects--a case control study

PURPOSE OF INVESTIGATION

The aim of this study was to evaluate the correlation between endometriosis and pathologies on an immune basis for the possible involvement of the immune system in the pathogenesis of endometriosis.

MATERIALS AND METHODS

In this retrospective study, data of 304 patients with endometriosis and 318 without endometriosis were collected in a uniform manner for both groups and inserted into two databases, respectively, for patients with and without endometriosis. The authors calculated the percentages of patients with allergies, autoimmune diseases, asthma in both groups, and later statistical analysis were performed with two different chi-square tests.

RESULTS

The results obtained have shown that patients with endometriosis have a higher prevalence of allergies (p = 0.0003) and coexistence of both allergies and autoimmune diseases (p = 0.0274), compared to those without.

CONCLUSIONS

The present study seems to support the possible association between endometriosis and allergic diseases.

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.

Fertility preservation in female cancer patients: an emerging challenge for physicians

Fertility preservation has become an issue of great importance in female cancer patients due to increasing survival rates and delayed childbearing. It is an emerging challenge for physicians, cause of several related issues (multidisciplinary approach, doctor-patient communication, ethical, religious and legal problems) and many unresolved questions. This review aims to update the latest literature data, summarizing the effects of cancer treatments on female fertility and the various options currently available to offer cancer patients the opportunity of future pregnancies. Many strategies exist for fertility preservation in young women and they should be assessed according to the patient's age, type of cancer, partner status and time available. Some techniques are well established, others are still experimental. The established methods include embryo cryopreservation, transposition of ovaries prior to radiation therapy, radiation shielding of gonads and conservative surgical approaches. The experimental methods include oocyte cryopreservation, in vitro maturation of oocytes, ovarian tissue cryopreservation and transplantation, and ovarian suppression. Improvement of these techniques as well as better characterization of their success rates and risks, await further investigation. Oocytes donation and gestational surrogacy represent the last options. Thus, the care of these patients is challenging, complex and requires a multidisciplinary approach. A close collaboration between Oncologists, Specialists in Reproductive Medicine, Gynecologic Oncologists and Endocrinologists is crucial for always offering the best possible option.

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.

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.

Borderline ovarian tumors, fertility-sparing surgery and pregnancy outcome

BACKGROUND

Borderline ovarian tumors (BOTs) represent a type of epithelial tumors having a biologic intermediate behavior between clearly malignant and straight benign tumors. Most of BOTs interest women during fertile age, for which it is necessary to consider a fertility sparing surgery.

AIM

To evaluate the clinical aspects and pregnancy rate of women affected by borderline ovarian tumors who have undergone fertility sparing surgery.

PATIENTS AND METHODS

A study of 22 patients affected by BOTs who have been treated with a fertility sparing surgery was conducted between January 2005 and October 2011 at Sant'Andrea Hospital, "Sapienza" University of Rome. The patients' characteristics analyzed were: age, histological type, tumor size, adnexal surgery, pre-operative serum CA-125, diagnostic circumstances, number of patients who became pregnant and number of overall pregnancies.

RESULTS

Among the 22 patients treated with a fertility sparing surgery, only sixteen wanted to get pregnant. Eleven patents out of 16 accomplished it. The pregnancy rate was 68.7%.

CONCLUSIONS

Fertility sparing surgery can be considered a safe procedure for young women affected by borderline ovarian tumors.

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.

[Venous thromboembolism in pregnancy: current state of the art]

Venous thromboembolism (VTE) is a major cause of maternal morbidity and mortality during pregnancy or early after delivery and it remains a diagnostic and therapeutic challenge. The latest Confidential Enquiry into Maternal Deaths (2006-2008) showed that VTE is now the third leading cause of direct maternal mortality, beside sepsis and hypertension. In particular the prevalence of VTE has been estimated to be 1 per 1000-2000 pregnancies. The risk of VTE is five times higher in a pregnant woman than in non-pregnant woman of similar age and postpartum VTE is more common than antepartum VTE. A literature search was carried out on Pubmed using the following key words: "venous thromboembolism", "pregnancy", "risk factors", "prophylaxis", "anticoagulants". Studies from 1999 onwards were analyzed. This review aimed to provide an update of whole current literature on VTE in pregnancy highlighting the most recent findings in diagnostic and therapeutic strategies, considering in detail risks and benefits of various techniques and drug classes, for both mother and fetus. Large trials of anticoagulants administration in pregnancy are lacking and recommendations are mainly based on case series and on expert opinions. Nonetheless, anticoagulants are believed to improve the outcome of pregnancy for women with current or previous VTE.

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

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.

Growth factors in preeclampsia: a vascular disease model. A failed vasodilation and angiogenic challenge from pregnancy onwards?

Preeclampsia is the major cause of maternofetal and neonatal morbi-mortality including intrauterine growth retardation, miscarriages and stillbirths. Inadequate vascular dilation and angiogenesis represent the crucial underlying defect of gravidic hypertension, denoting a failed response to the vasodilatory and pro-angiogenic challenge imposed by pregnancy, especially if multifetal. A similar pathogenesis appears involved in gestational diabetes. In this review we aimed to provide a hint on understanding the deeply involved angiogenic disorders which eventually culminate in utero-placental failure. The key players in these complex processes may be found in an intricate network of growth factors (GFs) and GF inhibitors, controlled by several vascular risk factors modulated by environment and genes, which eventually impact on early and late cardiovascular outcomes of mother and fetus.

GnRH antagonists in assisted reproductive techniques: a review on the Italian experience

Current Controlled Ovarian Stimulation (COH) for Assisted Reproductive Techniques (ART) pursues three main objectives: hypophyseal activity suppression, multiple follicle growth stimulation, and ovulation induction. By suppressing hypophyseal activity, it is possible to prevent untimely LH surge and allow the appropriate development of the leading follicle. The classical GnRH agonist long protocol is the most widely used in COH for ART. However, an alternative regimen based on GnRH antagonist has been recently introduced in clinical practice. As competitive antagonists, these drugs display an immediate and quickly reversible effect and they avoid hormonal withdrawal side effects. Moreover, this protocol shows undeniable advantages, including the shorter duration of the treatment, the lower amount of gonadotropin required, the shorter hormonal and ultrasound monitoring of patients, milder physical and emotional stress, and a lower risk of Ovarian Hyperstimulation Syndrome (OHSS). The use of GnRH antagonists was traditionally restricted to selected patients, as "poor responders" and women at high-risk of developing OHSS such as Polycystic Ovary Syndrome (PCOS) and patients who had previously experienced OHSS. These findings could prompt a trend to change from the standard agonist protocol to the antagonist protocol in all categories of patients. This review provides a comprehensive overview of the use of GnRH antagonist protocols applied both to IVF techniques and to IUI procedures in the Italian experience.

Imiquimod 5% cream versus cold knife excision for treatment of VIN 2/3: a five-year follow-up

BACKGROUND

Vulvar intraepithelial neoplasia (VIN) is a premalingnant condition. For long time, surgery was considered the first-line therapy in the treatment of high grade VIN. Imiquimod was recently introduced as an alternative to surgery.

AIM

To compare the overall complete response, the recurrence rate and the risk factors for relapse among patients with VIN 2/3 treated with Imiquimod or surgical excision.

PATIENTS AND METHODS

Eighty women who had histological diagnosis of VIN 2 and VIN 3 were enrolled in this prospective study. Patients immunocompromised, with recurrent VIN, with well differentiated type VIN or VIN 1 and women treated more than once were excluded from the study. Patients were divided into two groups: group A was treated with Imiquimod, group B underwent surgical excision. Patients' characteristics analyzed were: age, smoking, degree of the primary lesion, state of margins, multifocal disease. We have evaluated the recurrence rate, the relapse rate, and the overall complete response, considering as recurrence the onset of a lesion after an initial complete response to Imiquimod and/or after the surgical treatment and as relapse all patients who had a recurrence plus those with medical treatment failure.

RESULTS

Multifocal lesions (p = 0.03) and VIN 3 (p = 0.002) were associated with a higher risk of relapse. The recurrence rate was higher in the group B (p = 0.009), but the relapse rate was higher in the group A (p = 0.04). The overall complete response was better in the group B (p = 0.04).

CONCLUSIONS

Although the advent of new medical options can decrease the morbidity associated with invasive surgical procedures, surgical treatments remain the best treatment modality for VIN with regard to relapse and overall complete response.

In vitro fertilization stimulation protocol for normal responder patients

The aim of this prospective observational study is to determine the different outcomes of IVF/ICSI treatments after using antagonists or agonists of gonadotrophin-releasing hormone (GnRH) for controlled ovarian hyperstimulation (COH) in normal responder patients. Two hundred forty-seven patients undergoing IVF treatment at the Centre of Reproductive Medicine, Rome (CERMER), from January 2005 to December 2008, were included in the study. Patients were stimulated either with a standard long protocol with GnRH agonists (n = 156) or with GnRH antagonists (n = 91). The use of GnRH antagonists resulted in a significant reduction in the duration of the stimulation (Agonist Group 14.10 ± 2.25 vs Antagonist Group 11.34 ± 2.11; p < 0.001) and in the amount of gonadotrophin (IU of r-FSH) needed (Agonist Group 1878 ± 1109 vs Antagonist Group 1331 ± 1049; p = 0.0014). Moreover a lower number of cycles were cancelled with the antagonist protocol (4.39 vs 6.41%). The GnRH antagonist protocol, when compared to the GnRH agonist one, is associated with a similar clinical pregnancy rate, similar implantation rate, significantly lower gonadotrophin requirement and shorter duration of stimulation. For this reason, GnRH antagonists might be a good treatment even for normal responder patients undergoing IVF.

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.

Gynecologic sarcoma: a clinico-pathological review

Most of the cases showing good prognosis in literature are probably intermediate tumors between benign and malignant of undetermined malignant potential (UMP) and other tumors with intermediate features which are currently not considered among sarcomas. Misdiagnosis of a malignant lesion as a benign one has a tragic outcome for the patient. Best therapic choice for sarcomas remains surgery, while chemotherapy (CTX) and radiation therapy (RT) could be used in adjuvant settings. A major effort should be played in the understanding of biological features and behavior of the disease to address a better clinical practice. Uterine sarcomas are rare gynecological tumors; their incidence has been increasing during the last few years.

Colostrum in menopause effects on vaginal cytology/symptoms

The aim of this study was to assess the effects of three weeks of daily colostrum cream on vaginal cytology and local symptoms related to menopause. Genito-urinary symptoms and cell morphology were analyzed at time 0 (T0) and after three weeks (16 +/- days since the end of treatment) at time 1 (T1). Dyspareunia, vaginal dryness, and maturation index (MI) reached a statistically significant difference between T0 and T1. The results proved to be an alternative treatment for vaginal distress caused by lack of hormones in patients in which hormonal treatment is contraindicated.

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.

Fertility-sparing treatment of endometrial cancer precursors among young women: a reproductive point of view

BACKGROUND

Early-stage endometrial cancer and complex atypical hyperplasia are treated with hysterectomy and bilateral salpingo-oophorectomy. An emerging issue among younger women affected is the possibility of a fertility-sparing treatment with progestative therapy and close follow-up.

AIM

To assess the possibility of conceiving after a diagnosis of atypical endometrial hyperplasia among women younger than 40 years old, in term of delaying definitive treatment and achieving pregnancy.

MATERIALS AND METHODS

15 women younger than 40 years old with complex CAH or early carcinoma of the endometrium and a wish to preserve fertility. Progestins were administered orally for at least a 12 weeks period. Endometrial biopsies were used at follow-up.

RESULTS

In 11 women, a complete pathological remission of the disease was observed. 4 pregnancies were attained in 4 women. 3 showed progression and underwent definitive surgery at 18 months. 1 showed no response at 24 months and 3 cycles and was counseled to receive a hysterectomy.

CONCLUSIONS

A conservative approach in patients younger than 40 years appears a valid option, and a progestative therapy trial should be attempted whether a valid consensus is attained. Considering the risk to find AEH at biopsies and eventually a carcinoma at hysterectomy (25% of cases) a careful management is strictly required.

Recombinant luteinizing hormone priming in multiple follicular stimulation for in-vitro fertilization in downregulated patients

Follicle development is controlled amongst other factors by pituitary gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH) that act in synergy in completing follicle maturation. Exogenous gonadotropins, combined with gonadotropin-releasing hormone agonists, have been successfully used in patients with ovulatory disorders undergoing assisted reproduction. There is some evidence of a beneficial role of androgens or LH administration before FSH stimulation. This study was designed to verify whether the addition of LH in the early follicular phase, in downregulated patients undergoing follicular stimulation for assisted reproduction, would add benefits in terms of general outcomes and pregnancy rates. We compared two groups of patients one of which was treated with recombinant FSH (rFSH) alone and the other with rFSH plus recombinant LH (rLH), in the early follicular phase only. The number of eggs recovered was higher in the group treated with FSH only; however, the number of embryos available at transfer was similar in the two groups and, more importantly, the number of Grades I and II embryos was higher in the group pretreated with LH. Similarly, although biochemical pregnancy rate and clinical pregnancy rates were similar in both groups, a beneficial role of LH priming was demonstrated by the higher implantation rate achieved in these patients.

Evaluation of E6 and E7 mRNA expression in HPV DNA positive breast cancer

Several studies have suggested a possible role for HPV in the pathogenesis of the breast cancer. We investigated the presence of the HPV DNA in breast cancers and non malignant disease breast tissues by the use of a standard HPV detection method (INNO-Lipa HPV), in order to detect HPV DNA in metastatic nodes, to investigate a possible cervical HPV co-infection, and to evaluate the E6/E7 mRNA expression in HPV DNA positive breast cancer tissues. The rate of HPV infection was significantly higher in the cancer group than in controls (9/31 vs. 0/12, p = 0.04). One out of eight metastatic axillary nodes was positive for HPV infection; 2/3 of the positive HPV breast cancer patients were co-infected at the cervical site. The role of the virus in breast oncogenesis is still unclear, since our analysis failed in demonstrating the expression of viral E6 and E7 in positive HPV positive breast tumor tissues.

Prognostic Implication of High Risk Human Papillomavirus E6 and E7 mRNA in Patients with Intraepithelial Lesions of the Cervix in Relationship to Age

Since the introduction of the cytological screening programs, a significant reduction in the incidence of cervical cancer has been achieved. Almost all of these cancers are related to high-risk (HR) Human Papillomavirus (HPV) cervical infections. However, the natural history of HPV infection seems to be different in younger patients, resulting in a higher rate of regression. There is, therefore, the need to identify HPV-related biomarkers in order to enhance the effectiveness of screening of high-risk cytological lesions, in particular in women over 35 years of age. This study aims to evaluate the prognostic value of the HR HPV E6 and E7 mRNA expression in women with intraepithelial lesions of the cervix, older or younger than 35 years of age. One hundred and eighty-four HR HPV DNA positive patients with a low squamous intraepithelial lesion (LSIL) were tested for mRNA expressions, included in an observational study, and evaluated at follow-up with standard cytology up to 24 months from the mRNA test. The frequency of HSIL/LSIL cytology in the older cohort of mRNA positive patients was significantly higher compared to mRNA-negative patients, both at 1 and 2 years of follow-up ( Chi-square: p 0.007 and p 0.009), but this difference was not found in the younger cohort. According to our results, the E6/E7 mRNA test could be a biomarker for viral activity, useful in identifying patients at higher risk of abnormal cytology, and in implementing the management of HR HPV DNA-positive women over 35 years of age.

Myc down-regulation affects cyclin D1/cdk4 activity and induces apoptosis via Smac/Diablo pathway in an astrocytoma cell line

OBJECTIVES

We investigated the antiproliferative effect of Myc down-regulation via cell proliferation inhibition, cell cycle perturbation and apoptosis in two human astrocytoma models (T98G and ADF) steadily expressing an inducible c-myc Anti-sense RNA.

MATERIALS AND METHODS

Cell growth experiments were performed using the trypan blue dye exclusion test and cell cycle analysis was evaluated by flow cytometry. Cell cycle molecules were detected by Western blot analysis, co-immunoprecipitation and reverse transcription-polymerase chain reaction assays.

RESULTS

We showed that Myc down-regulation in astrocytoma cells led to G1 accumulation and an inhibition of cell proliferation characterized by S phase delay. Co-immunoprecipitation experiments detected formation of inactive cyclin D1/cdk4 complexes as evaluated by presence of an active unphosphorylated form of retinoblastoma protein, the best characterized target substrate for cyclin D1/cdk4 complex, in ADF pINDc-myc anti-sense 7 cells. We also found that either p57Kip2 "apice" or p27Kip1 "apice" inhibitors bound to cyclin D1/cdk4 complex, thus, suggesting that they cooperated to inhibit the activity of cyclin D1/cdk4. Moreover, c-Myc down-regulation led to activation of the apoptotic mitochondrial pathway, characterized by release of cytochrome c and Smac/Diablo proteins and by reduction of c-IAP levels through activation of proteasome-mediated protein degradation system.

CONCLUSIONS

Our results suggest that c-Myc could be considered as a good target for the study of new approaches in anticancer astrocytoma treatment.

Microcolposcopy in the diagnostic evaluation of abnormal cervical cytology: when and why to do it

Microcolposcopy is an in vivo cytological examination of the uterine cervix allowing the localization of exoendocervical precancerous lesions. The aim of this study was to assess the diagnostic reliability of microcolposcopy by means of correlation with histology, colposcopy and Pap test results. For the study, 256 patients with abnormal Pap test results were selected and subjected to colposcopy and microcolposcopy with the aim of evaluating the presence of any intraepithelial lesions. One hundred and nine of these patients were subjected to a biopsy. Colposcopy, histology and cytology results were compared with those obtained by microcolposcopy. In low-grade squamous intraepithelial lesion (LSIL) cytology cases, the percentage agreement on lesion grade between Pap test and microcolposcopy results was 74%, while in high-grade squamous intraepithelial lesion (HSIL) cytology cases, it was equal to 80%. The comparison between colposcopy and microcolposcopy showed a level of agreement of 72% for lower grades and 68% for higher grades. Finally, histology was in agreement with microcolposcopy in 73% of cervical intraepithelial grade 1 neoplasia (CIN 1) cases and reached 71% for CIN 2-3. Microcolposcopy proved to be accurate with regard to the diagnosis of lesion grade, and showed to be definitive in patients where cytology was positive for HPV infection and colposcopy was not able to identify any lesions.

Benefit of concomitant gastrointestinal and gynaecological evaluation in premenopausal women with iron deficiency anaemia

BACKGROUND

Iron-deficiency anaemia (IDA) is common in premenopausal women and menorrhagia is often considered responsible. Aim To evaluate prospectively the occurrence of bleeding and iron malabsorption related gastrointestinal (GI) diseases likely responsible of IDA in premenopausal women regardless of their menstrual flow.

METHODS

One hundred and eighty-seven premenopausal women [median age 39 (20-56) years] irrespective of their menstrual flow underwent gastroscopy with gastric and duodenal biopsies and faecal occult blood test (FOBT). Patients over 50 years, positive 1st degree family history for colonic cancer and/or positive FOBT underwent colonoscopy too.

RESULTS

Menorrhagia was present in 67.4% of premenopausal women. A possible GI cause of IDA was found in 129/187 patients; in 65.2% the cause of IDA was possibly related to iron malabsorption diseases. GI bleeding as a cause of IDA was found in seven patients. An exclusive GI cause of IDA was found in 26.7% of premenopausal women, whereas a possible GI cause was observed in 34.2% of menorrhagic premenopausal women. The main risk factor for the presence of likely GI causes was the presence of upper GI symptoms (OR 5.2: 95% CI = 1.6-16.4).

CONCLUSIONS

Most premenopausal women had a possible upper GI cause of IDA because of diseases related to iron malabsorption. Menorrhagia and a GI cause coexist in one-third of women with iron-deficiency anaemia.

Impact of endocrine disruptor chemicals in gynaecology

The potential hazardous effects that estrogen- and androgen-like chemicals may have both on wildlife and human health have attracted much attention from the scientific community. Endocrine disruptors (EDCs) are chemicals that have the capacity to interfere with normal signalling systems. EDCs may mimic, block or modulate the synthesis, release, transport, metabolism and binding or elimination of natural hormones. Even though potential EDCs may be present in the environment at only very low levels, they may still cause harmful effects, especially when several different compounds act on one target. EDCs include persistent pollutants, agrochemicals and widespread industrial compounds. Not all EDCs are man-made compounds; many plants produce substances (phytoestrogens) that can have different endocrine effects either adverse or beneficial in certain circumstances. Natural substances such as sex hormones from urban or farm wastes can become concentrated in industrial, agricultural and urban areas; thus, such wastes may be considered potential 'EDCs' for humans and/or wildlife. Much attention has focussed on changing trends in male reproductive parameters in relation to EDC exposure; however, studies on the female reproductive system have been less comprehensive. We have focussed this article on four major aspects of female reproductive health: fertility and fecundability, endometriosis, precocious puberty and breast and endometrial cancer.

Determination of cervicovaginal microorganisms in women with abnormal cervical cytology: the role of Ureaplasma urealyticum

OBJECTIVE

To evaluate the existence of an association between cervicovaginal infections and precancerous lesions of the uterine cervix, through determination of prevalent cervicovaginal micro-organisms, alone and in association with human papillomavirus (HPV), in patients with abnormal and normal vaginal cytology.

PATIENTS AND METHODS

Patients with abnormal vaginal cytology were divided into three study groups according to cytological findings: ASC-US, L-SIL and H-SIL. All patients underwent colposcopic examination and exoendocervical and vaginal sampling for microbiological and molecular analysis for detection of HPV-DNA, Ureaplasma urealyticum, Chlamydia trachomatis, Trichomonas vaginalis, mycetes and common bacteria. Results were compared with the patient group asymptomatic for cervicovaginal inflammation with negative vaginal cytology and colposcopy.

RESULTS

A high association between Ureaplasma urealyticum infection and the grade of cytological cervical lesion (27% for ASC-US, 35% for L-SIL and 45% for H-SIL) was found. Furthermore, 19% of the control group samplings were positive for Ureaplasma urealyticum, significantly less than that observed in the positive cytology groups. An interesting association of HPV with Ureaplasma urealyticum in patients with H-SIL vaginal cytology (83%), much higher than that observed in patients with slightly abnormal or normal vaginal cytology (56% for ASC-US, 49% for L-SIL, 40% for normal cytology) was also identified. In contrast, the association between Papillomavirus and multiple microorganisms seemed to decrease with the level of cellular dysplasia in 30% of controls, 33% of ASC-US, 32% of L-SIL and 17% of H-SIL.

CONCLUSION

The presence of a high Ureaplasma urealyticum level seems to be a cofactor of HPV infection, a necessary cause of precancerous lesions of the uterine cervix. The presence of Ureaplasma urealyticum may play a role both in initiating viral cellular anomalies and in viral persistence. It can be hypothesized that these initial processes are helped by a state of cervical inflammation, also supported by multiple microorganisms. It would, thus, be suggested for all patients who present with an abnormal PAP test to undergo a cervicovaginal microbiological examination to detect potentially pathogenic microbes for correct diagnosis and treatment, as well as a more complete follow-up of cervical cytological lesions.

Prediction of persistent vaginal intraepithelial neoplasia in previously hysterectomized women by high-risk HPV DNA detection

AIM

To estimate the incidence and latency of Vaginal Intraepithelial Neoplasia (VAIN) in women previously hysterectomized for benign/malign pathology and to evaluate the role of high risk HPVs in the prediction of persistent or recurrent disease.

SUBJECTS AND METHODS

830 women with prior hysterectomy for benign/malign pathologies followed by cytological scraping and vaginal colposcopy. Forty-four patients presented VAIN lesions confirmed by histopathological diagnosis. HPV DNA test was performed at the time of diagnosis. Patients were treated by Laser CO(2) vaporization and underwent follow-up by cytology, colposcopy for a mean period of 3 years. HPV DNA test was performed at 6 months after treatment and every years. Persistent or relapsed disease was confirmed by histopathology.

RESULTS

Incidence of VAIN in women hysterectomized for benign pathologies did not differ significantly from the malign group. VAIN degree was more severe in the hysterectomized patients with cervical malignancy and subsequently radiated respect to non-radiated patients. The HPV DNA test at 6 months after VAIN treatment showed fifteen positive cases: twelve HPV 16 (80%) and three HPV 18 (20%). In five cases HPV DNA test was positive with a persistent negative cytological smear during the years. Positivity to high-risk HPV (either 16 or 18) was significantly higher in the patients with relapse to VAIN (10/44, p<0.002).

CONCLUSIONS

We suggest to include HPV DNA test in addition to cytology in the follow-up of patients previously treated for VAIN, in order to predict VAIN persistence or progression in vaginal carcinoma before cytology becomes abnormal.

Oocytes cryopreservation: state of art

In the present review article we sought to analyze, on the basis of a systematic review, the indications, rationale of oocytes cryopreservation, as well as the techniques that improved the aforementioned procedure in order to higher the pregnancy rate in women undergoing that procedure. Moreover, we pointed out the importance of oocytes cryopreservation in the research field as oocyte banking may be of utmost importance to increase the availability of oocytes for research applications such as genetic engineering or embryo cloning. Oocyte freezing has 25 year of history alternating successes and setbacks. Human oocytes have a delicate architecture but are freezable. Clinical efficiency remains low, but healthy children have been born, indicating that chromosomally normal embryos can originate from frozen oocytes. Freezing protocols are not yet optimal and it is now desirable to combine empirical and theoretical knowledge.

Regression rate of clinical HPV infection of the lower genital tract during pregnancy after laser CO2 surgery

The objective of the study was to evaluate the effects of laser CO2 surgery during pregnancy to prevent clinical HPV infection recurrence after delivery and vertical infection. A case-control study was performed on 280 pregnant women affected by clinical HPV infection treated during pregnancy with 256 women treated three months after delivery. Follow-up was performed for a minimum of three colposcopic examinations for two years. Recurrence rates were calculated considering the number of positive findings for at least one colposcopic examination confirmed by biopsy after a negative control in a year. Statistical comparison of rates was performed by chi-squared and Fisher's exact test. Recurrence rates were higher in the women treated in postpartum (p < .01) than in the group treated during gestation (p < .005). Clinical HPV infections treated during the second trimester of pregnancy showed a sensitive decrease in recurrence-rate of infection. Rarity of respiratory papillomatosis makes conclusions inconsistent for the prevention of vertical infection.

Serum CA125 level modifications in women undergoing repeated IVF cycles

In the present paper, serum CA125 modifications in patients undergoing their first IVF cycle were compared with those of patients in their second attempt. A significant increase of this marker was detected in each group of patients at day 14 after embryo transfer. However, the level of CA125 monitored in the patients in their second attempt was significantly higher than that determined in patients undergoing their first ovarian stimulation. This condition does not influence either ovarian response or oocyte and embryo quality. Moreover similar IVF outcome was obtained. Therefore we propose that patients undergoing repeated assisted reproductive technology (ART) cycles may suffer from ovarian surface epithelial damage and/or altered cellular growth rate.

Anti human papillomavirus vaccine: the checkmate to human papillomavirus?

Cervical cancer is the second most frequently found neoplasia in women worldwide. At least 95% of cervical cancers contain viral DNA which, in 80% of cases, belongs to one of the human papillomavirus (HPV) viral types at high oncogenic risk: 16, 18, 31 and 45. HPV is, at this point, considered the first "necessary cause" of cervical cancer, against which primary prevention with a reduction in the risk of infection can be carried out. Numerous molecular biological studies have been conducted to identify the biological markers of this infection and to refine an effective and well tolerated vaccine capable of preventing HPV infection as well as possibly treating those cases in which the infection has already caused an HPV-related disease of the genital tract. In the near future, the real primary prevention of this disease will be conducted, similar to what occurred for Hepatitis B, using immunoprophylaxis with an anti-cancer vaccine.

Pelvic relapses in ovarian cancer. Role of CA-125, transvaginal ultrasound and color Doppler

From January 1995 to January 2001, 40 patients with epithelial ovarian cancer were treated at our Institution. Fourteen of these, with a clinical CR after surgery and platinum-based chemotherapy, were evaluated monthly by gynecological examination, Ca-125 RIA assay, pelvic ultrasound with transabdominal and transvaginal probe and color Doppler. Six pelvic relapses, from 1.5 to 3.0 cm, were detected by transvaginal ultrasound (US). They showed a rich neovascularization with low resistance, high flow, PI from 0.3 to 1.0 and RI < 0.5 in all cases. US did not reveal any sign of relapse in the remaining eight patients. In all cases of pelvic relapses ultrasonic signs of recurrence preceded the increase of Ca-125 by one to six months (average 3.8).

A new molecular and cytogenetic approach to sterility. A review of the literature

In the therapeutic procedure of conjugal fertility, the use of intracytoplasmic sperm injection (ICSI) has opened new possibilities when conventional in vitro fertilization (IVF) techniques are unsuccessful. Cytogenetic studies showed the presence of genetic anomalies in foetuses conceived with this technique. Starting from these considerations, through a data collection of the literature, the authors report the latest scientific findings on this problem. They show the limits of the knowledge about genetic risks linked to these techniques, increasingly imposing rigorous medical behavior and conscious choices of the couple.

[Ectopic pregnancy after in vitro fertilization and embryo transfer. Analysis of literature]

The incidence of ectopic pregnancy has dramatically increased in the last decade. The triggering factors may be different and among them there is the introduction of medical assisted procreation techniques. Tubal pathologies in 80% of women undergoing artificial insemination techniques, the transfer in the womb of more than one embryo and the method of the same embryo-transfer may influence the onset of an ectopic pregnancy. This study aims to detect the factors that can prevent or reduce thc incidence of this pathology, after a close examination of the literature.

Surgical treatment of invasive carcinoma of the vulva. Our experience

OBJECTIVE

The purpose of this study was to investigate the clinical findings, treatment and outcome of patients with vulvar carcinoma in the L'Aquila area.

METHODS

Fifteen cases of vulvar carcinoma seen between September 1991 and December 1999 at the Department of Obstetrics and Gynecology of the University of L'Aquila were reviewed. Clinical, pathologic, surgical and follow-up data were collected from patient records. Mean age at diagnosis was 66.4 years. All patients were evaluated through a careful medical history and physical examination, vulvoscopy, abdomino-pelvic CT or MR, urethrocystoscopy, rectocolonscopy and SCC, and CEA determination. Radical surgery included six patients treated by the Taussig-Way operation. Modified radical surgery accounted for nine patients treated by the Byron three-incision approach.

RESULTS

The major early complication was groin wound breakdown which occurred in four cases. The major late complication was chronic leg edema which was reported in six patients. The average number of nodes removed per patient was 19.5. Seven patients (46.7%) had a T2N0M0 pathologic stage, four (26.7%) were T2N1M0, four (26.7%) T1N0M0. Five patients died of local and distant recurrences within 37 months after surgical treatment; ten patients are alive, nine are apparently free from disease whereas one presented local and systemic recurrence within 18 months after surgery.

CONCLUSIONS

Vulvar carcinoma predominantly affects older women. Most patients in our series (11/15) had tumors more than 2 cm in diameter. Although the vulva is an external organ and early detection should be achieved, many patients presented with extensive primary lesions due to both patient and physician delay. Stage of disease, tumor size, and nodal metastases are potential prognostic factors useful in selecting patients for a more conservative surgical approach.
