The role of low-molecular-weight heparin in recurrent implantation failure: a prospective, quasi-randomized, controlled study.

Low-molecular-weight heparin did not provide any beneficial effect on pregnancy outcomes in patients with two or more implantation failures. Further trials are needed to confirm a trend in favor of low-molecular-weight heparin in the subgroup with women with three or more implantation failures.

Primary ovarian leiomyosarcoma: a review of the clinical and immunohistochemical features of the rare tumor.

Primary pure ovarian leiomyosarcomas constitute a malignant subgroup of ovarian smooth muscle tumors which comprise only 1% of ovarian tumors. Their origin, etiology, histologic features, clinical behavior, and optimal treatment are still obscure. Malignant behavior is almost always associated with any 2 of coagulative necrosis, cellular atypia, and mitotic index greater than 10. Immunohistochemical and electron microscopic evaluations may improve diagnostic accuracy. Traditionally, International Federation of Gynecology and Obstetrics (FIGO) staging and treatment of ovarian sarcomas have been the same as for epithelial ovarian carcinomas. Although surgery was performed for all cases, the extent of surgery is debatable. Benefit and modality of adjuvant therapy is controversial. The prognosis of primary pure ovarian leiomyosarcomas is extremely poor depending on tumor stage, tumor size, grade, and mitotic index and mostly recurs in abdomen and pelvis. Target Audience: Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader should be able to state how rare primary ovarian leiomyosarcoma (POLMS) is, explain that because of its rarity the best diagnostic and treatment modalities are not conclusive, and recall that the authors reviewed the literature to bring the readership current on POLMS.

Comparison of advanced stage mucinous epithelial ovarian cancer and serous epithelial ovarian cancer with regard to chemosensitivity and survival outcome: a matched case-control study

Objective The aim of this study was to compare clinicopathologic characteristics, surgery outcomes and survival outcomes of patients with stage III and IV mucinous epithelial ovarian cancer (mEOC) and serous epithelial ovarian carcinoma (sEOC). Methods Patients who had surgery for advanced stage (III or IV) mEOC were evaluated retrospectively and defined as the study group. Women with sEOC who were matched for age and stage of disease were randomly chosen from the database and defined as the control group. The baseline disease characteristics of patients and platinum-based chemotherapy efficacy (response rate, progression-free survival and overall survival [OS]) were compared. Results A total of 138 women were included in the study: 50 women in the mEOC group and 88 in the sEOC group. Patients in the mEOC group had significantly less grade 3 tumors and CA-125 levels and higher rate of para-aortic and pelvic lymph node metastasis. Patients in the mEOC group had significantly less platinum sensitive disease (57.9% vs. 70.8%; p=0.03) and had significantly poorer OS outcome when compared to the sEOC group (p=0.001). The risk of death for mEOC patients was significantly higher than for sEOC patients (hazard ratio, 2.14; 95% confidence interval, 1.34 to 3.42). Conclusion Advanced stage mEOC patients have more platinum resistance disease and poorer survival outcome when compared to advanced stage sEOC. Therefore, novel chemotherapy strategies are warranted to improve survival outcome in patients with mEOC.

Serum levels of adenosine deaminase and pregnancy-related hormones in hyperemesis gravidarum.

Abstract Objectives: We investigated the correlation between pregnancy-related hormones and serum adenosine deaminase (indicator of cellular immunity) level in women with hyperemesis gravidarum. Materials and methods: Twenty patients with hyperemesis gravidarum and 20 normal pregnancies were included in this prospective, case-control study. Serum adenosine deaminase levels, hematological parameters (white blood cells, neutrophil, monocyte and lymphocyte counts) and hormone levels (prolactin, progesterone, thyroid stimulating hormone, human chorionic gonadotropin β subunit, estradiol (E2)) were measured in all women. Interrelations of blood cell counts and hormone levels with serum adenosine deaminase levels were also investigated. Results: Serum adenosine deaminase, human chorionic gonadotropin β subunit, thyroid stimulating hormone, E2, progesterone and prolactin levels, and lymphocyte and monocyte counts in women with hyperemesis gravidarum were significantly higher than in controls but white blood cells, neutrophil, T3 and T4 levels were not different. Serum adenosine deaminase level correlated with E2, progesterone, lymphocyte, and monocyte levels for all patients. Conclusion: Elevated serum adenosine deaminase in patients with hyperemesis gravidarum may relate to high levels of E2 and progesterone.

Perinatal outcomes of idiopathic polyhydramnios

OBJECTIVE To investigate the perinatal outcomes of cases with idiopathic polyhydramnios. STUDY DESIGN Retrospective analysis of 160 singleton pregnancies that were under routine surveillance at the department of obstetrics from 2008 to 2010 was performed to assess perinatal outcomes. Finally, 59 cases were included as idiopathic polyhydramnios, and 101 cases were included as controls. Preterm delivery (<37 weeks), gestational age at birth, low birth weight (<2500 g), very low birth weight (<1500 g), macrosomia (>4000 g), 1- and 5-min APGAR scores <7, small for gestational age (SGA) fetuses, large for gestational age (LGA) fetuses, C-section rates, number of fetal distress, admission to neonatal intensive care unit (NICU) after delivery, neonatal death within the first 7 days, and deaths before the age of 1 year were selected as perinatal outcome variables. RESULT Significantly higher preterm labors and low 1- and 5-min APGAR scores were noted in the idiopathic polyhydramnios group compared with the control group. CONCLUSION Although perinatal outcomes are conflicting in literature, idiopathic polyhydramnios warrants close surveillance especially near term.

Laparoscopic near-infrared fluorescent imaging as an alternative option for sentinel lymph node mapping in endometrial cancer: A prospective study

BACKGROUND To evaluate feasibility of sentinel lymph node (SLN) mapping by using near-infrared fluorescent imaging and indocyanine green (NIR/ICG) integrated laparoscopic system in clinically uterine-confined endometrial cancer. MATERIALS AND METHODS Patients with clinically early-stage endometrial cancer were included in this prospective study. ICG was injected to the uterine cervix and NIR/ICG integrated laparoscopic system (Spies Full HD D-Light P ICG technology, Karl Storz, Tuttlingen, Germany) was used during the operations. SLN and/or suspicious lymph nodes were resected. Side specific lymphadenectomy was performed when mapping was unsuccessful. Systematic lymphadenectomy was completed following SLN algorithm steps. RESULTS Seventy-one eligible patients were analyzed. The overall, unilateral and bilateral SLN detection rates were 95.7%, 18.3%, 77.4%, respectively. There were 8 (11.2%) patients with lymph node metastasis. One of them was isolated para-aortic node metastasis. Negative predictive value, sensitivity and false negative rate for detecting lymphatic spread were 98.4%, 87.5% and 1.5%, respectively. CONCLUSION Sentinel lymph node mapping can easily be performed with high accuracy by using NIR/ICG integrated conventional laparoscopic system in endometrial cancer and almost all lymphatic spread can be detected.

Determination of risk factors and perinatal outcomes of singleton pregnancies complicated by isolated single umbilical artery in Turkish population

OBJECTIVE To address the possible risk factors, eventual pregnancy outcomes, and probable troubles in follow-ups of pregnancies complicated by an isolated single umbilical artery and to provide data on Turkish cases in such an aspect that ethnic divergences may have influence. MATERIAL AND METHODS A total of 16568 singleton pregnancies that were delivered between May 2006 and May 2013 were retrospectively screened. Ninety-three fetuses were found to have an isolated single umbilical artery. One-hundred pregnancies that did not show any structural or chromosomal abnormalities were randomly selected from the rest of the cases to establish the control group. IBM SPSS Statistics 20.0 software was utilized for statistical analysis. Non-parametric data were analyzed with Mann-Whitney U test and were presented as means±standard deviations. P values less than 0.05 were statistically significant. For the adjustment of confounding factors, odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by multiple logistic regression analysis. RESULTS The incidence of small for gestational age (SGA) fetuses and hypertensive disorders in pregnancy was found to be significantly higher in cases with an isolated single umbilical artery (p<0.001 and p=0.022, respectively). Maternal smoking was found to be independently associated with the occurrence of an isolated single umbilical artery (OR: 3.556; 95% CI: 1.104-11.45). The risk of preterm birth was not higher in the study group (OR: 0.538; 95% CI: 0.576-2.873). The incidence of cases who underwent cesarean delivery because of non-reassuring fetal heart trace was similar in the study and control groups (p=0.499). CONCLUSION Attention should be paid to the development of hypertensive disorders in cases with a diagnosis of an isolated single umbilical artery, and parents should be counseled properly, including the information on increased risk of SGA. Strict follow-up of pregnancies complicated with an isolated single umbilical artery in terms of preterm birth seems unfeasible except in cases with accompanying risk factors for preterm labor.

Comparison of laparoscopy and laparotomy in surgical staging of clinical early stage endometrial cancer: A report of early experiences from Turkey

The objective of this study was to assess the feasibility of laparoscopy (LS) in endometrial carcinoma staging. Clinical early stage endometrial cancer patients (n = 153) staged by LS or laparotomy (LT) were compared. A total of 40 (26.1%) patients were treated by LS and 113 (73.9%) by LT. All patients underwent pelvic lymphadenectomy. Lymphadenectomy has been extended to para-aortic space in 55% of the LS group and 70% of the LT group. The majority of patients had stage I–II disease. The median numbers of removed pelvic and para- aortic lymph nodes were similar in two groups (p values 0.213 and 0.199, respectively). Body mass index (BMI) (kg/m2) was higher in the LT group (31.2 vs 27.4, p < 0.05). Operation time, age, tumour histology, para-aortic lymphadenectomy and complication rates were similar in the two groups. Four (10%) patients in the LS group and 12 (10.6%) in the LT group had recurrence of disease (p = 1.0). There was no statistical difference for overall survival between the two groups. In conclusion, these findings showed that in endometrial carcinoma cases, laparoscopy has provided adequate staging and similar survival rates with laparotomy.
