Endometriotic Uterocutaneous Fistula after Cesarean Section

Endometriosis outside the pelvis is rare and most cases occur in surgical scars after operations involving the female genital tract. Fistulae involving the uterus are also very rare, usually being the result of postpartum and postoperative complications. In the present report, a case of a 44-year-old patient with an endometriotic uterocutaneous fistula is described. The patient presented 6 years after her fourth cesarean section with a painful nodule on the cesarean scar, which was bleeding during menstruation. The lesion extended to the uterine fundus, connecting the endometrial cavity with the skin. This is merely the second case of a uterocutaneous fistula to be reported in the literature and the first case developed on grounds of endometriosis.

Apert Syndrome: The Current Role of Prenatal Ultrasound and Genetic Analysis in Diagnosis and Counselling

Apert syndrome is a rare congenital malformation syndrome characterized by the triad of cutaneous and progressive bony syndactyly, midfacial hypoplasia and craniosynostosis. Two missense mutations of the gene encoding the fibroblast growth factor receptor 2 (FGFR2) have been implicated in most cases. We report a case of Apert syndrome detected on prenatal ultrasound. Postnatal genetic analysis showed, for the first time, that the previously reported P253R mutation of the FGFR2 gene is also prevalent in southeast Europe. After prenatal sonographic detection of anomalies suggestive of Apert syndrome, parents should be counselled about prognosis and risk of recurrence, and the option of amniocentesis should be offered.

Ultrasound and MR-imaging in preoperative evaluation of two rare cases of scar endometriosis

Scar or incisional endometriosis is a rare, often misdiagnosed, pathologic condition of the abdominal wall. Two cases of incisional endometriosis are presented. Both patients presented with atypical cyclic pain and palpable nodules on scars of previous cesarean sections. In both cases, the mass was totally excised, after accurate preoperative evaluation with 2-D ultrasound, power Doppler and MRI. Microscopic examination confirmed the preoperatively presumed diagnosis of cutaneous endometriosis. In cases of suspected scar endometriosis, preoperative diagnostic imaging is valuable in determining the extent of disease, thus enhancing accurate and total excision.

Pelvic echinococcus mimicking multicystic ovary

An unusual case of pelvic echinococcus cyst is presented, appearing initially on transvaginal ultrasound as a pelvic mass mimicking a multicystic ovary. A similar mass in the liver raised preoperatively the suspicion of echinococcosis, making an open surgical procedure preferable to laparoscopy. Diagnosis was confirmed pathologically after removal of the cyst. Though their location in the pelvis is rare, echinococcal cysts should be considered in the differential diagnosis of pelvic masses, especially in patients from endemic areas. Evaluation of previous medical history and current symptoms, together with the ultrasonographic findings, is important for correct diagnosis and appropriate management. Copyright

Amniotic Fluid and Maternal Serum Metabolic Signatures in the Second Trimester Associated with Preterm Delivery

Preterm delivery (PTD) represents a major health problem that occurs in 1 in 10 births. The hypothesis of the present study was that the metabolic profile of different biological fluids, obtained from pregnant women during the second trimester of gestation, could allow useful correlations with pregnancy outcome. Holistic and targeted metabolomics approaches were applied for the complementary assessment of the metabolic content of prospectively collected amniotic fluid (AF) and paired maternal blood serum samples from 35 women who delivered preterm (between 29 weeks + 0 days and 36 weeks +5 days gestation) and 35 women delivered at term. The results revealed trends relating the metabolic content of the analyzed samples with preterm delivery. Untargeted and targeted profiling showed differentiations in certain key metabolites in the biological fluids of the two study groups. In AF, intermediate metabolites involved in energy metabolism (pyruvic acid, glutamic acid, and glutamine) were found to contribute to the classification of the two groups. In maternal serum, increased levels of lipids and alterations of key end-point metabolites were observed in cases of preterm delivery. Overall, the metabolic content of second-trimester AF and maternal blood serum shows potential for the identification of biomarkers related to fetal growth and preterm delivery.

Epidemiology of HPV infection and current status of cervical cancer prevention in Greece: final results of the LYSISTRATA cross-sectional study.

The objective of this study was to assess the overall prevalence of the human papilloma virus (HPV) infection and distribution of high-risk HPV (hrHPV) types in Greece and evaluate the participation of women in primary and secondary cervical cancer prevention. This was a prospective, cross-sectional study carried out between October 2005 and January 2011 in Greece; 5379 women filled out the study questionnaire anonymously. 5107 women underwent cervical HPV-DNA testing, either by Hybrid Capture 2, followed by restriction fragment length polymorphism-PCR, or by the Abbott Real-Time High-Risk HPV test. Overall, 5.8% (295/5107) of women were positive for hrHPV infection. The most common hrHPV type was HPV-16 (24.8% among infected women; 1.4% overall), followed by HPV types 31, 35, 53, 18, 51, 56, 58, 52, 39, 66, 45, 33, 59, and 68. In respect to primary prevention of cervical cancer, acceptance of anti-HPV vaccination appeared to decrease over time (from 85–89.9% annually during 2005–2008 to 64.4–60.5% during 2009–2010, P<0.001). In respect to secondary prevention, only 30.3% of women had regular (annually for more than 5 years) Pap smears; regular gynecologic examinations, Papanicolaou testing, and knowledge of HPV were all associated with various demographic parameters (age, education, place of residence, occupation, and income). The prevalence of hrHPV infection in Greece is similar to that in other European countries; the most common type is HPV-16. The initially relatively high acceptance of HPV vaccination decreased after licensing of the vaccine. Demographic parameters appear to influence participation in cervical cancer screening.

Mucocele of the Vermiform Appendix with Sonographic Appearance of an Adnexal Mass

Mucocele of the vermiform appendix is caused by mucus retention in its lumen, due to obstruction or hyperproduction. Appendiceal malignancy can be the underlying cause, making accurate preoperative diagnosis imperative. In women, it can sometimes present as an adnexal mass. A rare case of an appendiceal mucocele is presented, mimicking a cystic tumor of the right adnexum, both clinically and ultrasonographically. In addition, serum levels of CA-125 were increased. This is the first case of a mucocele of the appendix simulating an adnexal mass on ultrasound with increased levels of CA-125 to be reported. This clinical entity should be considered in patients presenting on ultrasound with a right-sided adnexal mass as a rare potential diagnosis.

Endometriosis and ovarian cancer risk: a systematic review of epidemiological studies.

Background: A possible etiological association between endometriosis and ovarian cancer has been repeatedly reported in the literature. Objective: Our aim was to evaluate published epidemiological data on this issue. Review Methods: We conducted an extensive search of the literature in MEDLINE, of articles ever published until February 2014, using the key-words “endometriosis” and “ovarian” and one of the following terms in the title: “cancer” or “malignancy” or “malignant” or “tumor” or “neoplasia” or “neoplasm” or “transformation.” Retrieved papers were checked for further relevant publications. Results: Overall, our search yielded 1 prospective cohort study, 10 retrospective cohort, and 5 case–control studies. A meta-analysis of these studies was not considered to be appropriate, due to differences in data reporting, study design, and adjustment for confounding factors. Limitations: The main limitation of studies found, with one exception, was the lack of operative confirmation of endometriosis. Conclusion: An association of endometriosis with clear-cell and endometrioid ovarian cancer was a consistent finding in most studies. On the other hand, existing epidemiological evidence linking endometriosis with ovarian cancer is insufficient to change current clinical practice. Prospective cohort studies, with prior laparoscopic confirmation, localization, and staging of endometriosis are needed, in order to further clarify this issue.

Long-term follow-up after cervical cancer treatment and subsequent successful surrogate pregnancy

Preservation of fertility is a major concern for premenopausal women after diagnosis of cervical cancer. Successful surrogate pregnancy after treatment for cervical cancer has very rarely been reported. In the present report, a case of successful surrogate pregnancy after radical hysterectomy, lymphadenectomy and ovarian transposition for cervical cancer, followed by radiation therapy, is presented. After stimulation of the transposed ovaries using the short gonadotrophin-releasing hormone (GnRH) analogue protocol, four oocytes were retrieved transabdominally from the genetic mother. IVF followed and two embryos were transferred to the surrogate mother, leading to an uneventful singleton pregnancy, and ultimately normal vaginal delivery of a healthy female infant at term. The unique aspect in this case is the long-lasting favourable outcome for both genetic mother and child, observed during 8.5 years of follow-up, the longest follow-up period reported to date in such cases.

Prenatal management and postnatal separation of omphalopagus and craniopagus conjoined twins

Two cases of prenatally diagnosed conjoined twins are presented: a set of omphalopagus twins sharing a common liver, and a set of craniopagus with involvement limited to the skull. In both cases, prenatal diagnosis allowed accurate planning of pre- and postnatal management. Prenatal management involved serial imaging and counseling with participation of different specialists according to imaging findings. In the rare case of conjoined twins, an interdisciplinary approach is required, with feto-maternal specialists playing a pivotal role in co-ordinating teamwork and planning successive stages of management.
