GnRH antagonist rescue of a short-protocol IVF/ICSI cycle and GnRH agonist triggering to prevent ovarian hyperstimulation syndrome: two case reports.

OBJECTIVE: To describe two clinical cases concerning patients at risk of developing severe ovarian hyperstimulation syndrome (OHSS) during in vitro fertilization (IVF) stimulation. DESIGN: Description of clinical management and outcomes of patients using an IVF antagonist rescue protocol to prevent OHSS. SETTING: Reproductive medicine unit, University Hospital. MATERIALS AND METHODS: Two infertile patients undergoing controlled ovarian stimulation (COS) for IVF/intracytoplasmic sperm injection (ICSI) presenting with high risk of OHSS. IVF/ICSI patients following COS under short protocol and high risk of OHSS were managed by withdrawing the agonist and replacing it with an antagonist and triggering ovulation with an agonist bolus. Main outcome measures included incidence of OHSS, oocytes retrieved, and pregnancy rates. RESULTS: None of the two patients developed OHSS. None of the patients had metaphase II retrieved oocytes at oocyte retrieval. CONCLUSIONS: Use of COS with short protocol in an IVF/ICSI cycle carries a risk of severe OHSS. Rescuing the cycle by withdrawing the agonist and replacing it with an antagonist and triggering ovulation with an agonist bolus is not always effective and should not be used if short time interval between agonist replacement with antagonist and ovulation triggering is available.

Maternal hyperthyroidism after intrauterine insemination due to hypertrophic action of human chorionic gonadotropin: a case report.

PURPOSE OF INVESTIGATION: To report a rare case of maternal hyperthyroidism after intrauterine insemination due to hypertrophic action of hCG. MATERIALS AND METHODS: A 36-year-old woman after successful intrauterine insemination and triplet pregnancy, developed hyperthyroidism with resistance to medical treatment. RESULTS: All signs of hyperthyroidism resolved and the results of thyroid function tests returned to normal without any medication after embryo meiosis. CONCLUSIONS: De novo maternal hyperthyroidism may develop during pregnancy as a result of pathological stimulation of the thyroid gland from the high levels of hCG hormone that can be seen in multiple pregnancies. The risk of hyperthyroidism is related to the number of fetuses. Reversibility of symptomatology can be seen after fetal reduction of multiple pregnancies.

Trocar metastases in laparoscopic approach for gynecologic malignancies. A short review of the literature.

INTRODUCTION: Compared to laparotomy, laparoscopy has many benefits for patients, such as shorter recovery and lower morbidity rates. Port site metastases after laparoscopic approach in the treatment of gynecologic malignancies are uncommon. The purpose of this review is to identify and summarize possible risk factors for port-site metastases in patients undergoing laparoscopic surgery in the ambit of gynecologic oncology. DISCUSSION: The precise incidence of port-site metastases is not well known because many patients are not followed-up during the whole postoperative period. Possible risk factors that can increase the risk of port-site metastases can be the presence of large masses in the abdomen, especially in the presence of concomitant ascites and in patients treated for ovarian carcinomas. Different theories have been postulated in order to explain the development of port site metastases during laparoscopy for oncological patients. CONCLUSIONS: Patient selection is an essential factor that can influence the incidence of port site metastases in gynecological patients. Robust data regarding port site metastases in gynecologic oncology are needed.

IVF/ICSI frozen replacement cycles; every cycle? Opinion expressed after a systematic review of the literature.

OBJECTIVE: To determine whether in vitro fertilization (IVF), frozen replacement cycles offer better outcomes than fresh cycles in order to support, or not, a possible shift towards total replacement of fresh IVF/intracytoplasmic sperm injection (ICSI) cycles from frozen elective transfers (FETs). STUDY DESIGN: Systematic review; opinion paper. RESULTS: Initial results seem to support a shift in current practice towards frozen cycles. CONCLUSION: Initial results may support replacement all fresh IVF/ICSI cycles with FETs, as this could be a safer and equally effective strategy. However, robust evidence from randomized controlled trials is needed if this will be generally applied.

The role of mTOR signaling pathway in premalignant and malignant cervical lesions.

PURPOSE OF THE STUDY: Aberrant activation of the Akt/mTOR/pS6 signaling pathway has been identified in various types of cancer and is under investigation in cervical cancer. The purpose of this study was to assess the expression of the phosphorylated/activated forms of Akt (upstream molecule), 4E-BP1 and pS6 (downstream molecules) in biopsy samples of cervical low grade squamous intraepithelial lesions (LSIL), high grade squamous intraepithelial lesions (HSIL), and squamous cell carcinoma (Ca) compared to normal cervical epithelium. MATERIAL AND METHODS: The study included 38 cases diagnosed as LSIL, 31 cases as HSIL, 29 cases as Ca, and eight control cases from normal cervix. Immunohistochemistry was used to assess the expression of pAkt, p4E-BP1 and pS6. RESULTS: Statistical analysis revealed significant differences between HSIL and Ca groups compared to controls regarding intensity, positivity, and total scores for all three molecules (p < 0.001). A trend for higher expression with increasing grade of dysplasia was demonstrated. CONCLUSION: These results strongly support the view that the mTOR signaling pathway is involved in cervical carcinogenesis.

A rare case report of squamous-cell carcinoma arising from mature cystic teratoma of ovary.

The most frequent ovarian germ cell tumors are mature cystic teratomas (MCTs), composing 10-25% of all ovarian neoplasms. MCTs have the potential of undergoing malignant transformation, typically in postmenopausal women, with a frequency of 0.17-3%, with squamous cell carcinoma being the most common malignant tumor arising from MCT. We present the rare clinical entity of a squamous cell carcinoma arising from a mature cystic teratoma in a 56-year-old premenopausal woman as well as diagnostic and therapeutic route followed.

Primary fallopian tube carcinoma: a case report and mini-review of the literature.

Primary fallopian tube carcinoma (PFTC) is an uncommon gynecologic tumor, responsible for 0.14% to 1.8% of genital malignancies, with a mean incidence of 3.6 per million women per annum. The factors that contribute to its appearance are not well-known. Overall survival percentages for patients with PFTC are generally low. Although the preoperative diagnosis rarely occurs and it is usually first confirmed by the pathologist, an earlier diagnosis occurs with early clinical manifestation and prompt investigation leading to better prognosis. Both PFTC and epithelial ovarian cancer (EOC) are treated with similar surgical and chemotherapy methods. The authors report a case of a patient with bilateral high grade serous carcinoma of the fallopian tube, whose initial presentation was bilateral cystic adnexal masses and serosanguinous discharge, with no other pelvic involvement. This article also reviews in brief and presents updates of this rare gynecological malignancy.

Fertility preservation in women with early stage cervical cancer. Review of the literature.

Within the last decades, the percentage of diagnosed cervical cancer in women of reproductive age has increased. The possibility of diagnosing small cervical tumors (< or = twocm) in childbearing age, can be explained due to the fact that many women, are aware of the benefits of Pap smear or colposcopy examination. Many demand a more conservative policy to handle such lesions in order to have an uneventful pregnancy in the near future.

Morbus Bourneville: a case report and review of the literature.

Tuberous sclerosis (TS) or tuberous sclerosis complex (TSC), also known as Bourneville disease or Bourneville-Pringle disease, is an autosomal dominant disorder classically characterized by the presence of hamartomatous growths in multiple organs. A combination of symptoms may include seizures, developmental delay, behavioral problems, skin abnormalities, and lung and kidney diseases. The authors present a case of a 18 year-old female patient with a history of TS, epileptic episodes, mental retardation, and papillary formations in multiple organs located at the abdominal, axillary, cervical, facial, and genital region.

Effect of tamoxifen on postmenopausal endometrium.

PURPOSE: The objective of this study was to evaluate the effect oftamoxifen on the endometrium of45 postmenopausal women with breast cancer, as evidenced by hysteroscopic, ultrasound, histological methods, and by immunohistochemical investigation of the expression of Bcl-2 and Ki67. MATERIALS AND METHODS: Forty-five postmenopausal women with breast cancer (ER and/or PgR positive) undergoing tamoxifen therapy for six to 48 months, were selected from the files of the 2nd Department of Obstetrics and Gynecology, University of Athens Aretaieion Hospital, among a total of 120 patients treated from 2004-2009. RESULTS: The ultrasound findings during the follow-up period revealed 18 cases of thickened endometrium, 14 cases of suspected polyps, one case with accumulation of endometrial fluid, and 12 cases of heterogeneous endometrial echo texture. The patients had undergone hysteroscopy because of thickened endometrium (18/45 patients), postmenopausal bleeding (14/45 patients), and polyps (13/45 patients). The endometrial tissue samples were examined in the Pathology Department of Aretaieion Hospital and showed in 23 cases with adenomatous endometrial polyps, 15 cases with endometrial cystic atrophy, two cases with adenomatous hyperplasia, and five cases with mucosal endometrial adhesions. Immunohistochemical investigation of Bcl-2 and KJ67 expression was undertaken on paraffin blocks and showed elevated expression in the cases with endometrial polyps and hyperplasia, in contrast to atrophic endometria. CONCLUSION: Long-term tamoxifen therapy of postmenopausal women with breast cancer is associated with uterine pathology. Ultrasonography alone is useful in asymptomatic patients selecting cases with increased endometrial thickness for further investigation. Hysteroscopy is an accurate method for diagnosing endometrial disease because it provides a direct view of the uterine cavity, reveals focal lesions, and enables targeted biopsies to be performed at the same time. Pathological findings show elevated expression of Ki67 and Bcl-2 in hyperplastic endometria and adenomatous polyps, consistent with an elevated glandular cell proliferation due to tamoxifen effect.

Uterine tamponade balloon for the management of massive hemorrhage during cesarean section due to placenta previa/increta.

OBJECTIVE: Uterine tamponade with the Bakri catheter is effectively used as a treatment in postpartum hemorrhage and as a means to prevent fertility. CASE: We present a case of a 40-year-old pregnant woman who had a massive hemorrhage during cesarean section who was successfully treated with a tamponade balloon. Furthermore, we comment on a similar technique--Logothetopoulos pack--which was first developed and used in our department in the early years of the previous century. CONCLUSION: A conservative technique such as the Bakri catheter is an alternative intermediate step to control postpartum hemorrhage when pharmaceutical methods fail and before proceeding to obstetric hysterectomy.

Management of ASCUS findings in Papanicolaou smears. A retrospective study.

AIM: Atypical squamous cells of undetermined significance (ASCUS) are a cervical cytologic finding category suggestive but not definitive of squamous intraepithelial lesions. ASCUS remains an incompletely described entity and accounts for even 5%-10% of reported Papanicolaou (Pap) smears. The management of women with such cytologic findings remains controversial. The aim of this study was to evaluate the cytology laboratory findings with regards to ASCUS diagnosis, using cervical Pap smears, and colposcopic biopsies, as well as their management. MATERIALS AND METHODS: This is a retrospective study of patients with ASCUS Pap smears taken during the period January 2010 - December 2010 in the Second Department of Obstetrics and Gynecology, Aretaieion Hospital. RESULTS: During the study period, 657 Pap smears were examined at the Aretaieion Hospital; moreover, seven patients, whose Pap smears were cytologically diagnosed with ASCUS, were referred from other clinics, providing a total of 42 cases with a descriptive diagnosis of ASCUS for review. Of the 42 cases, eight were not studied because they were either lost in follow-up or they did not have available data. The remaining 34/42 patients were evaluated by colposcopic examination and directed biopsies where necessary. The ratio of ASCUS to low-grade squamous intraepithelial lesion (LGSIL), high-grade squamous cell intraepithelial lesion (HGSIL) or squamous cell carcinoma (SCC) was 5/34, 1/34, and 0/34, respectively. In the 34 ASCUS cases evaluated by colposcopy, the age distribution varied from 22 to 54 years. Eight of 34 cases did not have a child, 7/34 were primigravida, 18/34 were secondi-gravida, and 1/34 had four children. Four out of 34 cases were postmenopausal, 3/34 referred no history of abnormal bleeding, 21/34 were smokers, 6/34 used oral contraceptives, 2/34 used intrauterine devices, 1/34 took replacement of hormones, 4/34 had prior abnormal Pap smears human papillomavirus (HPV), or 1/34 had previous cancer (breast cancer). Colposcopy was inconclusive in 4/34 patients, while 8/34 cases were negative for Schiller and acetic acid tests and also had normal colposcopy. Infectious organisms were found in 8/34 patients with ASCUS, including actinomyces (1/8), trichomonas (5/8), and candida albicans (2/8). Histologic tests revealed 16/34 koilocytosis cases, 5/34 LGSIL, 1/34 HGSIL, and 0/34 SCC. CONCLUSION: The dilemma in the management of patients with an ASCUS diagnosis still exists as a significant problem for clinicians.
