[Show abstract][Hide abstract] ABSTRACT: Sexually transmitted diseases threaten every sexually active individual, whereas especially our younger adults, as more IT literate, should be better familiarized with the various methods of STDs protection as well as of the traditional and modern contraception. Our purpose was to investigate and compare the awareness of 18-45 years old adults from urban and rural areas on sexual and reproductive health issues and to establish any potential new strategies for its best promotion. Two hundred individuals coming from either our capital, which represents the purest urban dimension of our Greek lifestyle spectrum, or one specific carefully selected, as a characteristic opposite non-urban dimension in our lifestyle scale, rural town, were stratified randomly and answered a three-part closed ended questionnaire. Useful results were extracted, like, for example, although 29.5% reported that they were in a committed relationship, trusted traditional methods of contraception and protection from STDs, like condom, 18% out of them has not been regularly using it. Moreover the percentage of hormonal contraception was low (9%). The younger the people and the more the urban lifestyle they have adopted, the lesser cautious on their choice of sexual partners are. Men still seem to be alternating between sexual partners and perform “one night stands” more frequently than women. Finally we came to the conclusion that the awareness on sex and reproduction is not so developed as we would expect from our adequate standard of living before the years of the economic crisis (<2010). We noticed many cases of fragmentary information, false view and high-risk sexual behavior. Moreover, mainland residents seem to be less informed about the current data of STDs and contraception, even though their behavior is less risky.

Osteoprotegerin (OPG) is a soluble glycoprotein, involved in bone metabolism. OPG is also found in other tissues, and studies have shown that it is expressed in vascular smooth muscle cells. OPG has been implicated in various inflammations and also has been linked to diabetes mellitus. Increased serum OPG levels were found in patients with diabetes and poor glycemic control. Furthermore, prepubertal children with type 1 diabetes have significantly increased OPG levels. Receptor activator of nuclear factor kappa-B ligand (RANKL) is not found in the vasculature in normal conditions, but may appear in calcifying areas. OPG and RANKL are important regulators of mineral metabolism in both bone and vascular tissues. Few data are available on the relationship between plasma OPG/RANKL levels and endothelial dysfunction as assessed using noninvasive methods like ultrasound indexes, neither in the general population nor, more specifically, in diabetic patients. The aim of our review study was to investigate, based on the existing data, these interrelationships in order to identify a means of predicting, via noninvasive methods, later development of endothelial dysfunction and vascular complications in diabetic patients.

[Show abstract][Hide abstract] ABSTRACT: Decreased expression of E-cadherin has been associated with poorly differentiated endometrial carcinomas and poorer outcomes.
The purpose of this study was to examine the distribution of E-cadherin immunohistochemical expression in specimens from primary endometrial carcinomas and its relation to classical clinicopathological prognostic factors.
Surgically-resected tissues of 30 patients with primary endometrial carcinomas were studied. Histological type and grade, depth of myometrial invasion, lymph-vascular space invasion, fallopian tube or ovarian invasion, and the presence of tumoral necrosis were evaluated. Immunohistochemical examination was performed on deparaffinized four-microm-thick sections.
The mean age of patients was 65 years (+/- 11.41). The 63.54% of carcinomas were moderately/poorly differentiated. No statistical correlation was found between the score or intensity of E-cadherin immunohistochemical staining (strong or moderate positive expression) and the clinicopathological factors tested.
The association of E-cadherin immunoreactivity with the standard clinicopathological factors seemed to be contradictory. The classical clinicopathological factors remain the most important prognostic parameters.

[Show abstract][Hide abstract] ABSTRACT: Introduction
Autoimmune oophoritis is a rare condition, which provokes ovarian failure with either primary amenorrhea or secondary amenorrhea and a subsequent loss of fertility and ovarian hormonal function. The purpose of this report is to document the clinical findings from two patients with autoimmune oophoritis.
Two cases of autoimmune oophoritis are presented whose histopathological findings were consistent with international literature. Both cases were histopathologically characterised by lymphocytic and plasmacytic inflammatory infiltrations around the cystic follicles. The inflammation was located both in the theca and granular layers.
Patients with autoimmune oophoritis should be recognised by the histopathology of the ovarian biopsies as they are at an increased risk of developing other autoimmune disorders.
[Show abstract][Hide abstract] ABSTRACT: It is well known that the innate immunity system, involving the contribution of monocytes and macrophages, may dysfunction in fetuses and preterm neonates. Monocytes are capable of differentiating into dendritic cells (DCs) or into mucosal macrophages during certain infections and of producing inflammatory mediators such as TNF- α (tumor necrosis factor-alpha), nitric oxide, and reactive oxygen species. Fetuses as well as neonates are prone to infections as a result of a defective mechanism within the above mononuclear system. Monocyte function in fetuses and preterm neonates depends on the phagocytic and oxidative capacity of macrophages and their antigen-adhesion ability. Functional rather than anatomical impairment is probably the underlying cause, while a defective production of cytokines, such as TNF- α , IL-6 (Interleukin 6), IL-1 β (Interleukin 1 beta), and G-CSF (Granulocyte Colony-Stimulating Factor), has also been involved. The insufficient production of the above inflammatory mediators and the phenomenon of endotoxin intolerance, which latter occurs during entry of any antigen into the premature neonate, place preterm neonates at higher risk for infections. Existing research data are herein presented which, however, are deficient and fragmental, this accounting for the fact that the precise pathophysiology of these disturbances is not yet fully clarified.

[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: The purpose of the study was to determine the incidence of gene expression of Oct-4 and DAZL, which are typical markers for stem cells, in human granulosa cells during ovarian stimulation in women with normal FSH levels undergoing IVF or ICSI and to discover any clinical significance of such expression in ART. METHODS: Twenty one women underwent ovulation induction for IVF or ICSI and ET with standard GnRH analogue-recombinant FSH protocol. Infertility causes were male and tubal factor. Cumulus--mature oocyte complexes were denuded separately and granulosa cells were analyzed for each patient separately using quantitative reverse-transcription--polymerase chain reaction analysis for Oct-4 and DAZL gene expression with G6PD gene as internal standard. RESULTS: G6PD and Oct-4 mRNA was detected in the granulosa cells in 47.6% (10/21). The median of Oct-4 mRNA/G6PD mRNA was 1.75 with intra-quarteral range from 0.10 to 98.21. The OCT-4 mRNA expression was statistically significantly correlated with the number of oocytes retrieved; when the Oct-4 mRNA expression was higher, then more than six oocytes were retrieved (p=0.037, Wilcoxon rank-sum). No detection of DAZL mRNA was found in granulosa cells. There was no additional statistically significant correlation between the levels of Oct-4 expression and FSH basal levels or estradiol peak levels or dosage of FSH for ovulation induction. No association was found between the presence or absence of Oct-4 mRNA expression in granulosa cells and ovarian response to gonadotropin stimulation. Also, no influence on pregnancy was observed between the presence or absence of Oct-4 mRNA expression in granulosa cells or to its expression levels accordingly. CONCLUSIONS: Expression of OCT-4 mRNA, which is a typical stem cell marker and absence of expression of DAZL mRNA, which is a typical germ cell marker, suggest that a subpopulation of luteinized granulosa cells in healthy ovarian follicles (47.6%) consists of stem cells, which are not originated from primordial germ cells. Absence of Oct-4 gene expression in more than half of the cases means probably the end of the productive journey of these cells, towards the oocyte.

[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: The purpose of the study was to determine the incidence of survivin gene expression in human granulosa cells during ovarian stimulation in Greek women with normal FSH levels, undergoing IVF or ICSI and to discover any correlation between levels of gene expression and clinical parameters, efficacy of ovulation or outcomes of assisted reproduction. METHODS: Twenty nine women underwent ovulation induction for IVF or ICSI and ET with standard GnRH analogue-recombinant FSH protocol. Infertility causes were male and tubal factor. Cumulus--mature oocyte complexes were denuded and the granulosa cells were analyzed for each patient separately using quantitative reverse transcription polymerase chain reaction analysis for survivin gene expression with internal standard the ABL gene. RESULTS: The ABL and survivin mRNA were detected in granulosa cells in 93.1%. The expression levels of survivin were significantly lower in normal women (male infertility factor) compared to women with tubal infertility factor (p = 0.007). There was no additional statistically significant correlation between levels of survivin expression and estradiol levels or dosage of FSH for ovulation induction or number of dominant follicles aspirated or number of retrieved oocytes or embryo grade or clinical pregnancy rates respectively. CONCLUSIONS: High levels of survivin mRNA expression in luteinized granulosa cells in cases with tubal infertility seem to protect ovaries from follicular apoptosis. A subpopulation of patients with low levels of survivin mRNA in granulosa cells might benefit with ICSI treatment to bypass possible natural barriers of sperm-oocyte interactions.

[Show abstract][Hide abstract] ABSTRACT: Ovarian steroid cell tumours, not otherwise specified (NOS) are rare sex cord-stromal tumours of the ovary. These tumours should be considered a cause of isosexual precocious puberty in children and virilisation in adults.
We report a case of 40-year-old woman with mental handicap who presented with 3 years of amenorrhea and progressive virilisation. Pelvic ultrasonography identified a 6.19 × 6.15 cm well-defined echogenic-multilobular mass arising from the left ovary. Fluid in the cul-de-sac was noted. Colour Doppler examination with endovaginal ultrasonography showed high vascularity of the tumour with low resistance to flow. A computed tomography (CT) scan of the upper and lower abdomen showed a lobular mass with diaphragms in the left adnexal structure and fluid in the cul-de-sac; no adrenal gland enlargement or additional tumour was detected. Laboratory analysis revealed increased levels of serum total testosterone. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Histological examination showed a benign steroid cell tumour, NOS without evidence of necrosis, haemorrhage or invasion. The immunohistochemical study showed that the tumour cells were positive for inhibin, CD 99, Melan A and vimentin and negative to CK AE1, CK AE3, progesterone and estrogen receptors.
Careful medical history, physical examination, laboratory serum values and imaging studies are helpful in making the pre-operative diagnosis. Steroid cell tumours, NOS are usually benign, unilateral and characterised by the composition of two similar-appearing polygonal cell types. They differ from Leydig cell tumours in the lack of crystals of Reinke in their cytoplasm.
[Show abstract][Hide abstract] ABSTRACT: Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that develop in the wall of the gastrointestinal tract and their diagnosis during pregnancy or puerperium is extremely rare.
A 28-year old patient presented with acute abdomen due to hemoperitoneum from a large mass arising of the small intestine with distended vessels on its top and a ruptured superficial vessel bleeding into the peritoneal cavity. The patient was at the tenth postpartum day of her first pregnancy. The preoperative diagnosis was a possible ovarian or uterine mass. After an emergency exploratory laparotomy a segmental bowel resection was performed, removing the tumor with a part of 3-cm of the small intestine. Histology revealed GIST with maximum diameter of 13 cm and mitotic rates more than 5 mitoses per 50 high power fields with some atypical forms, indicating a high risk malignancy. Immunohistochemical staining of the tumor tissue demonstrated strongly positive reactivity to CD 117 (c-kit) and CD34 in almost all the tumor cells. The patient was treated with oral imatinib mesylate (Gleevec) 400 mg daily for one year. Three years after surgery, the patient was alive without evidence of metastases or local recurrence.
Considering that only few patients with gastrointestinal stromal tumors have been reported in the obstetrical and gynecological literature, the awareness of such an entity by the obstetricians-gynecologists is necessary in order to facilitate coordinated approach with the general surgeons and oncologists for the optimal care of the patients.

[Show abstract][Hide abstract] ABSTRACT: This was a retrospective clinical study of emergency hysterectomy performed between 1997 and 2007 at two tertiary hospitals to study incidence, indications and maternal mortality. We included all women who required emergency hysterectomy to control major postpartum hemorrhage after delivery, following a pregnancy of at least 24 weeks' gestation, regardless of the mode of delivery. There were 12 emergency hysterectomies, with a frequency of 0.0726% among 16,521 deliveries. Indications included uterine atony (4 cases), uterine rupture (3 cases), uterine retroversion (2 cases), abnormal placentation (2 cases) and amniotic fluid embolization (1 case). The result was two maternal deaths. Although emergency obstetric hysterectomy is a life saving operation, it is associated with high maternal mortality.

[Show abstract][Hide abstract] ABSTRACT: PURPOSE: Termination of pregnancy in the second trimester with misoprostol is safe and effective, but there is very limited published experience of its use in women with one or more previous cesarean sections. Uterine rupture might occur when misoprostol and oxytocin are used for pregnancy termination at the second trimester in women with previous uterine scars. In the English literature there are some case-series of studied women with a history of previous cesarean sections, in which misoprostol was used for second trimester termination of pregnancy. However, many different protocols have been used with different doses of misoprostol and different intervals between doses and it is difficult to draw definite conclusions. Therefore, the decision to attempt pregnancy termination in the second trimester in cases with previous uterine scar should be made on a case-by-case basis, after consideration of the number of previous cesarean sections and gestational age, and careful labor monitoring of these patients.
[Show abstract][Hide abstract] ABSTRACT: Background. Teratomas are the most common tumors. They are usually localized in the sacrococcygeal area, while the pharyngeal localization is very rare. The number of cases of stomatopharyngeal teratomas detected prenatally via sonography is very small. Case Report. We present the case of a 24-year-old primipara at 18 weeks' gestation, that at the routine ultrasound scan, the fetus was found with an echogenic mass, filling the stomatopharyngeal cavity and protruding from the mouth. Other abnormalities were not found. Termination of pregnancy was achieved using misoprostol. A female stillborn fetus with a weight of 250 g and length of 25.5 cm was delivered. The postmortem and pathologic examination confirmed the diagnosis. Conclusion. Pharyngeal teratomas can be diagnosed with the use of ultrasounds in utero facilitating parents' counseling in early time.

The tumor may also occur around the tendon, synovium, or joint capsule. Rare sites are the tongue, testes and liver. Chondroma of the fallopian tube is extremely rare, with only two reports in the English literature. We present the first reported case of extraskeletal chondroma of the fallopian tube causing transportation impairment of the fertilized ovum in a 32-year-old gravida 1, para 1 woman.
[Show abstract][Hide abstract] ABSTRACT: Congenital anomaly of the Müllerian duct system can result in various urogenital anomalies including uterus didelphys with blind hemivagina and ipsilateral renal agenesis. The diagnosis of this condition is usually made after menarche, but its rarity and variable clinical features may contribute to a diagnostic delay for years after menarche.
A 24-year-old woman presented to the emergency room of the Department of Obstetrics and Gynecology complaining of severe worsening lower abdominal pain, vomiting and pus-like vaginal discharge. Physical examination revealed acute abdomen with diffuse lower abdominal tenderness, rebound and muscular resistance. Cervical and vaginal observation was impossible because of the patient's discomfort. Bimanual gynecological examination showed high tenderness cervical motion. Transabdominal ultrasound scan was performed and the radiologist interpreted the ultrasonographic findings as existence of a pelvic mass with mixed echogenicity. The preoperative diagnosis was ruptured tubo-ovarian abscess and emergency laparotomy was performed. Free pus in the pelvis was found. Also, a double uterus with an elongated and inflammatory right fallopian tube with pus passing out of its fimbrial end was observed. Vaginal examination under general anesthesia revealed an obstructed right hemivagina with vaginal pus-like discharge from a small fistula hole on the septate vagina. The final diagnosis was uterus didelphys with unilateral imperforate right hemivagina and pyocolpos. Transvaginal resection of the vaginal septum was performed and a large amount of pus and blood was spilled out. Postoperatively, intravenous pyelography demonstrated agenesis of the right kidney.
We demonstrated the difficulty in making a correct diagnosis of this rare congenital anomaly of the female genital tract, especially after many years since menarche. This condition should be considered to prevent misdiagnosis or suboptimal treatment and decrease morbidity and unnecessary surgical procedures.
[Show abstract][Hide abstract] ABSTRACT: The existence of a longitudinal vaginal septum with double cervix communicating bilaterally with a nonseptate uterine body and normal adnexa is an unusual müllerian anomaly.
A 43-year-old woman presented with menorrhagia and duplication of the cervix and vagina. Afibromatous uterus was suggested by clinical examination and confirmed by ultrasonography. The patient underwent total abdominal hysterectomy with bilateral salpingooophorectomy. The surgical specimen revealed a fibromatous uterus with double cervix communicating bilaterally with a nonseptate uterine body; both adnexa were normal.
This rare müllerian anomaly is inconsistent with the classical embryologic theory of caudal to cranial müllerian development but supports the alternative embryologic hypothesis suggested by Müller et al, according to which fusion and absorption begin at the isthmus and proceed simultaneously in both the cranial and caudal directions.

[Show abstract][Hide abstract] ABSTRACT: Aggressive angiomyxoma is a rare, benign but locally aggressive mesenchymal neoplasm, which occurs almost exclusively during the reproductive years of women. A 28-year-old woman developed an aggressive angiomyxoma within the left labium minus of the vulva. The tumor was excised, but the lesion was expanded to the surgical margins. Microscopically, sections showed many walled vessels of various sizes, a loose myxoid and collagenous stroma and stellate and spindle-shaped neoplasmatic cells. Immunohistochemically, the neoplasmatic cells showed strong positivity for vimentin and desmin and moderate positivity for CD34 and estrogen receptors. In conclusion, aggressive angiomyxoma of the vulva should be distinguished from the benign and malignant myxoid tumors or tumor-like conditions of vulva. The pathologic and immunohistochemic characteristics, the difficulties in determining the surgical margins and the treatment of this tumor are discussed. Also, the international literature is reviewed.

[Show abstract][Hide abstract] ABSTRACT: Angiomyofibroblastoma is a rare mesenchymal tumor. This study presents the clinical, histologic, and immunohistochemical features of an angiomyofibroblastoma of the vagina occurring in an 80-year-old breast cancer patient under prolonged treatment with tamoxifen. Histologically, the tumor was characterized by alternating hypercellular and hypocellular edematous zones and small- to medium-sized blood vessels, which were characteristically thin walled. The tumor cells were spindle shaped (mainly) or round shaped (occasionally) arranged in cords and nests. The stroma was edematous and contained inflammatory cells, especially lymphocytes and mast cells. Immunohistochemistry of the tumor cells revealed diffuse and intense immunoreactivity for vimentin and desmin. The staining for estrogen receptors and progesterone receptors was positive, with a percentage of 70% and 40%, respectively. In conclusion, the tumor was diagnosed as an angiomyofibroblastoma based on its typical histologic and immunohistochemical features. The expression of estrogen and progesterone receptors suggests that it might arise as a neoplastic proliferation of hormonally responsible mesenchymal cells. Tamoxifen may exert stimuli effects upon mesenchymal cells.
