Background: This study aimed to explore the potential influence of kisspeptin (KISS1) levels on the etiology of placenta previa for early pregnancy diagnosis., Methods: The study included 20 pregnant women diagnosed with placenta previa and 20 pregnant woman with normal pregnancies between 2021 and 2022. Plasma KISS1 levels were determined through biochemical analysis, while genetic analysis assessed KISS1 and KISS1 receptor gene expression levels. Immunohistochemical methods were employed to determine placenta KISS1 levels., Results: The evaluation of KISS1 concentration in serum revealed a significant decrease in the placenta previa group compared to the control group (P < .001). KISS1 gene expression level 0.043-fold decreased in the placenta previa group (P < .001). Furthermore, the KISS1 receptor gene expression level increased 170-fold in the placenta previa group., Conclusions: Results from biochemical, immunohistochemical, and genetic analyses consistently indicated significantly reduced KISS1 expression in patients with placenta previa. These findings suggest a potential link between diminished KISS1 levels and the occurrence of placenta previa. KISS1 may play a critical role in the etiology of placenta previa. Detailed studies on angiogenesis, cell migration and tissue modeling should be conducted to understand possible mechanisms., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction Familial Mediterranean fever (FMF) is an inflammatory rheumatic disease that affects people in their reproductive period. The aim of this study was to investigate the number of gravida, ovarian reserve, and ovarian doppler characteristics in FMF patients. Methods The study design is cross-sectional. Between November 1, 2018, and October 31, 2019, 40 FMF patients, and 40 age-matched volunteers were included in the study. Early follicular phase follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E2), progesterone, and anti-Mullerian hormone (AMH) levels, as well as ovarian volume, antral follicle count (AFC), ovarian stromal artery doppler findings, and pelvic pathologies, were evaluated. Results The number of gravida, and the AFC was significantly higher in the control group (16.00 ± 5.22) compared to the patients with FMF (13.00 ± 4.09) (p = 0.026). LH values were significantly higher in the FMF group. Thirteen patients (32.5%) received anakinra and colchicine, and 27 patients (67.5%) received only colchicine. There was no significant difference between the patients receiving anakinra, and the patients receiving colchicine in terms of AMH, FSH, AFC, and E2 values. Conclusion FMF patients were found to have low gravida and AFC, and a significant portion was observed to have pelvic fluid and hydrosalpinx. In conclusion, the presence of pelvic fluid, hydrosalpinx, and low AFC persist in FMF patients despite colchicine and/or anti-interleukin-1 treatments. The low gravida may be related to these pathologies detected in patients with FMF., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Okuyucu et al.)

COVID-19 has been a threat throughout the world since December 2019. In attempts to discover an urgent treatment regime for COVID-19, hydroxychloroquine (HCQ) and chloroquine (CQ) have been on solidarity clinical trial. However, many countries have pulled HCQ and CQ from their COVID-19 treatment regimens recently, some countries still continue using them for patients who have previously started HCQ and CQ and they may complete their course under the supervision of a doctor. HCQ and CQ are 4-aminoquinoline drugs and it is safe to use them for autoimmune diseases, rheumatoid arthritis, systemic lupus erythematosus and malaria as well. Determination of CQ, HCQ and their metabolites in biologic fluids and in pharmaceuticals has great importance, especially for pharmacokinetics, pharmacodynamics and epidemiological studies. In this review, liquid chromatographic methods developed in the last 10 years were summarized focusing on sample preparation and detection methods for HCQ and CQ determination in biological fluids and pharmaceutical preparations. It is hoped that this article could be helpful to facilitate the use of these drugs in clinical trials or drug research studies as it provides comprehensive information on the reported analytical methods., (© The Author(s) 2020.

Background: It is very common to offer low molecular weight heparin (LMWH) medications to women with unexplained habitual abortion, to increase the livebirth rate. Although no benefit from LMWH has been clearly demonstrated, examination of the effects of enoxaparin on placental structure is lacking., Objective: To assess placental structural changes in pregnancies treated with enoxaparin, compared with controls., Design and Setting: Case-control study in an obstetrics and gynecology unit of a tertiary-level university hospital in Turkey., Methods: Forty patients who had had term pregnancies and live births but also histories of habitual abortion were recruited for this study. Placentas were sampled using a systematic random sampling method. Tissue samples were obtained, embedded and sectioned for routine histological analyses. Hematoxylin and eosin staining was used. Surface area and length estimates from placental components were evaluated by using Image J. Cell proliferation and apoptosis were also assessed via immunohistochemistry., Results: There were no significant differences between the groups regarding maternal age, abortion rate, birth weight or gestational age. Comparison of the enoxaparin and control groups showed that there were no significant differences in terms of surface area and ratios of placental components. We found that Bcl-2 was generally expressed at high levels in the enoxaparin group, while there was no difference in terms of Ki-67 between the groups., Conclusions: This study demonstrates that enoxaparin did not show any significant effect on the placental structure of cases that had histories of habitual abortion.

Aim: To investigate the effect of thiol/disulfide homeostasis on the number of oocytes retrieved and metaphase 2 (M2) oocytes in patients undergoing in vitro fertilization., Method: A prospective study of 94 patients who were admitted to the in vitro fertilization clinic was conducted. Serum samples were taken on the oocyte pick-up day and kept until the analysis. Thiol and disulfide were measured in order to evaluate the total thiol/disulfide., Results: A statistically significant correlation was observed between disulfide and M2., Conclusion: This study provides an inexpensive and noninvasive method to measure oxidative stress, and suggests that there is a positive correlation between the number of M2 and disulfide, resulting in low-impact oxidative stress., Competing Interests: Financial & competing interests disclosure The authors have no relevant affiliations or financial involvement with any organization or entity with a financial interest in or financial conflict with the subject matter or materials discussed in the manuscript.

Objective: The aim of this study is to evaluate the embryo flash migration after 60 min from embryo transfer in fresh and frozen cycles., Design: 80 fresh and 81 frozen embryo transfers implemented Ondokuz Mayıs University between December 2017 and May 2018 were included in this prospective study. The fresh transfers performed at day 3 embryos as the frozen transfers were day 5 embryos. The distance between the embryo and the fundus was measured in the sagittal plane within 1 min of the transfer. After 60 min of bed rest the distance between the air bubble and the fundus was measured. The transfers were divided into three groups based on the migration of the embryos after the transfer. Embryos were classified as static if they were within 15 mm of their initial position. If they moved more than 15 mm towards the cervix or more than 15 mm towards the fundus, it was classified as cervical and fundal, respectively., Results: There was a statistically significant difference in embryo flash movements between frozen and fresh transfers (p < 0.05). In fresh transfers 48 patients (%60.0) were cervical, 14 patients (%17.5) were static and 18 patients (22.5%) were fundal. In frozen embryo transfers 31 patients (38.3%) were cervical, 31 patients (38.3%) were fundal and 19 (23.5%) patients were static., Conclusion: We found that cervical migration is lower in frozen transfers than in fresh transfers. This result may be related with the day of embryo or the endometrium in fresh or frozen cycles. Because in this study the embryos transferred were day 3 in fresh cycle and day 5 in frozen cycle. In frozen transfers there was not any significant difference in embryo position between pregnant and non-pregnant group. But in fresh transfers the cervical migration was significantly high in non-pregnant patients (p < 0.05)., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Purpose of Investigation: Primary sarcomas account for of 2-3% of all female genital tract cancers and ovaries are unusual sites for sarcomas. The authors aimed to report a case of primary ovarian sarcoma., Materials and Methods: A 46-year-old woman presented with abdominal pain and distention. Abdominal MRI revealed a 20-cm-sized complex mass in the right adnexa and ascites. Preoperative CA-125 was 289 U/ml. She underwent optimal debulking surgery and diagnosed with undifferentiated pleomorphic sarcoma with focally rhabdomyosarcomatous differentiation., Results: The patient presented with severe abdominal pain and distention 32 days after the operation and recurrent disease was diagnosed. First cure of adjuvant chemotherapy was administered, but she died 15 days later., Conclusion: Coexistence of undifferentiated pleomorphic sarcoma and rhabdomyosarcoma shows highly aggressive behavior and its prognosis is extremely poor. To the best of the authors' knowledge, this is the second case report of the coexistence of these type tumors in the literature.

Aim: Pre-eclampsia is a hypertensive disease that is characterized by high blood pressure and proteinuria after 20 gestational weeks and complicates 3-8% of all pregnancies. It is classified as either mild or severe pre-eclampsia according to severity, and the aim of this study was to investigate the structural differences between these two classifications., Methods: Placenta samples were collected from 68 women who underwent cesarean delivery. Total volume of villi and numerical density of vascular endothelial growth factor (VEGF)- and placental growth factor (PIGF)-positive cells were estimated on stereology and evaluated using one-way ANOVA., Results: There was no significantly difference in total villi volumes between the groups (P > 0.05). In contrast, on immunohistochemistry, the numerical density of VEGF-positive cells in severe pre-eclampsia was significantly different to the control and mild pre-eclampsia groups (P<0.05). Additionally, the numerical density of PIGF-positive cells in the mild and severe pre-eclampsia group was significantly higher than in the control group (P<0.01)., Conclusion: There is no relationship between villi volume and pre-eclampsia, although growth factors play a role in placental changes. The present results were supported by histopathology and several studies in the literature., (© 2015 Japan Society of Obstetrics and Gynecology.)

Background: The study aimed to evaluate changes in hematologic parameters, including white blood cell, platelet count, platelet indices, the platelet to lymphocyte and neutrophil to lymphocyte ratios in patients with early and advanced stages of epithelial ovarian cancers., Materials and Methods: The study included 100 patients with epithelial ovarian cancer who underwent primary staging exploratory laparotomy. Preoperative hematologic parameters, tumor histopathologic type, grade, stage and serum CA-125 levels were retrospectively analyzed. These parameters were compared between the patients with early (stage I-II) and advanced (stage III-IV) ovarian cancer., Results: White blood cell count and platelet indices, including mean platelet volume, platelet distribution width and platelet crit did not show a statistically significant difference between groups with early and advanced ovarian cancer. However, the neutrophil to lymphocyte ratio, platelet count, the platelet to lymphocyte ratio and CA-125 level showed a statistically significant difference between the two groups (p<0.05, p<0.01, p<0.001, p<0.01 respectively)., Conclusions: It was found that the neutrophil to lymphocyte ratio, platelet count and the platelet to lymphocyte ratio increased with the increasing stage of ovarian cancer. Furthermore, it was seen that the platelet to lymphocyte ratio is an independent prognostic factor related to the stage of epithelial ovarian cancer.

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare müllerian duct anomaly with uterus didelphys, unilateral obstructed hemivagina, and ipsilateral renal agenesis. Patients with this syndrome generally present after menarche with pelvic pain and mass and, rarely, primary infertility in later years. Strong suspicion and knowledge of this syndrome are mandatory for an accurate diagnosis. A 14-year-old female patient presented with acute retention of urine and abdominopelvic pain. Her condition was diagnosed with the use ultrasonography and magnetic resonance imaging as a case of HWW syndrome. She was treated with vaginal hemiseptal resection. The HWW syndrome should be considered among the differential diagnoses in girls with renal anomalies presenting with pelvic mass, symptoms of acute abdominal pain, and acute urinary retention.
