Objective: Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion which is located in the distal fallopian tube and causes high grade serous ovarian carcinoma (HGSOC). The incidence of STIC for women underwent risk reducing salpingo-oophorectomy for BRCA mutation varies from 0.6 to 7% and its clinical outcomes are still unclear.

Introduction And Hypothesis: There has been a great deal of discussion about mesh complications in urogynecology in recent years. However, awareness of other doctors who are not urogynecologists is unknown. This study was aimed at determining the level of awareness of mesh discussions among medical doctors whose specialty is not urology or gynecology.

Objective: To evaluate whether antenatal magnesium sulphate (MgSO4) exposure has a neuroprotective effect against hearing impairment in premature newborns.

Material And Methods: Retrospective cohort study was performed with prematurely (<37 weeks) delivered newborns at a tertiary university hospital. Newborns of 92 women who received MgSO4 infusions (study group) for various indications were compared to newborns of 147 women who did not receive MgSO4 infusions (control group).

Objective: To investigate the effect of challenging factors on laparoscopic hysterectomy trends within twenty-four years.

Population And Method: This was a trend analysis study of 7558 women who underwent hysterectomy for benign indications between 1995-2018 in Bursa Uludag University Hospital, Turkey. A trend analysis of obesity, previous laparotomy (≥3) and uterine specimen weight (≥500g) was applied for abdominal hysterectomy (TAH), vaginal hysterectomy (VH), and laparoscopic hysterectomy (TLH) rates in this period.

Introduction And Hypothesis: Mesh-related problems are significant complications of laparoscopic sacral colpopexy. The conventional technique precludes performing laparoscopic sacral colpopexy without using a mesh. We describe the Ozerkan modification for laparoscopic sacral colpopexy using a polyester fiber suture instead of a standard mesh and report 1-year objective and subjective outcomes.

Objectives: There is no standardized treatment modality or a generally accepted guideline in cesarean scar pregnancy (CSP) treatment. The aim of this study is to retrospectively evaluate the outcomes of the different treatment modalities used in CSP treatment.

Material And Methods: 31 CSP patients retrospectively evaluated between May 2011 and February at Uludag University Hospital in Bursa, Turkey included in the study.

Aim: The aim of this study is to compare demographic characteristics, operative data, and complication rates of women who underwent total laparoscopic hysterectomy by the skeleton uterus technique (Skeleton-TLH) with those of women who underwent TLH by the standard technique (Standard-TLH) in a university teaching and research hospital.

Materials And Methods: This retrospective study included 932 laparoscopic hysterectomies in a university teaching and research hospital between January 1, 2013 and December 31, 2017. Clinical characteristics, operative outcomes, and complications were recorded and compared for the two techniques.

Introduction And Hypothesis: Numerous studies have found that the short-term results of laparoscopic sacrocolpopexy for pelvic organ prolapse are safe and effective. This study evaluates the long-term results of the laparoscopic sacrocolpopexy operation between the urology and gynecology branches.

Methods: A prospective study enrolling 206 patients was conducted to evaluate laparoscopic sacrocolpopexy as a surgical treatment for vaginal vault prolapse from 2011 to 2014.

Study Objective: Minimally invasive surgical procedures have shown significant improvement over the last 20 years. Today, nearly half of the surgeries, including oncology, are performed with minimally invasive methods. In obstetrics and gynecology surgery practice, laparoscopy can now be used in almost all operations.

Objective: To compare the effects of total laparoscopic hysterectomy with bilateral salpingectomy (TLH-BS) and total abdominal hysterectomy with bilateral salpingectomy (TAH-BS) on ovarian function among women of reproductive age.

Study Design: One hundred and three patients with a diagnosis of benign uterine disorder were divided into two groups in this prospective longitudinal study. Patients who had never had sexual intercourse and patients with uterovaginal disproportion underwent TAH-BS (n=57), and the remaining patients (n=46) underwent TLH-BS.

Objective: To determine the importance of placental membrane microscopic chorionic pseudocysts (MCP) in preeclamptic and normal placentas and evaluate the association between MCP and neonatal complications in preeclamptic patients.

Materials And Methods: In this prospective case-control study, microscopic examination of placentas was performed, including MCP count, in 33 preeclamptic and 35 normal control pregnant women from December 2008 to May 2009. The MCP were counted in placentas for each patient and modeled as a continuous variable to assess the difference between the two groups.

Article Synopsis
  • The study aimed to investigate whether tamoxifen (TMX) exposure causes a lasting reduction in ovarian reserve in female mice.
  • Results showed that mice treated with TMX had lower serum anti-Müllerian hormone (AMH) levels and smaller ovaries compared to the control group, indicating impaired ovarian function.
  • However, while TMX affected the growth of certain follicle types, it did not reduce the number of primordial follicles, suggesting TMX primarily disrupts hormone-sensitive follicles rather than the overall follicle pool.

Objective: To evaluate the role of adiponectin and visfatin in the pathophysiology of pre-eclampsia (PE) and how their concentrations correlate with the severity of the disease and neonatal outcomes.

Study Design: A prospective case-control study was carried out in 52 preeclamptic and 28 healthy pregnant women during the third trimester. The maternal plasma concentrations of adiponectin and visfatin were determined.

Study Question: Do the presence of endometriomas and their laparoscopic excision lead to a decrease in ovarian reserve as assessed by serum anti-Müllerian hormone (AMH) levels?

Summary Answer: Both the presence and excision of endometriomas cause a significant decrease in serum AMH levels, which is sustained 6 months after surgery.

What Is Known Already: No previous comparison of serum AMH levels between women with and without endometrioma has been reported. However, studies have suggested a decline in serum AMH levels 1-3 months after endometrioma excision but long-term data are needed.

Objective: To investigate the polymorphism rates and possible roles of glutathione-s-transferase M1, T1, and P1 gene polymorphisms in the predisposition to endometrial cancer in Caucasian women.

Materials And Methods: Serum samples and medical records were collected from 53 Caucasian women with newly diagnosed endometrial cancer and 67 women of the same race without any known history of cancer. Multiplex polymerase chain reaction (PCR) analysis was used to assess glutathione-s-transferase M1 (GSTM1) and T1 gene polymorphisms.

Aims: This study was conducted to investigate whether insertion/deletion (I/D) polymorphism of angiotensin-converting enzyme (ACE) gene and polymorphisms in glutathione S-transferase (GST) M1 and T1 genes are associated with increased risk for preeclampsia.

Materials And Methods: Sixty-three patients with hypertensive disorder of pregnancy and 85 controls were evaluated in a prospective case-control study. All subjects were genotyped by polymerase chain reaction (PCR) followed by agarose gel electrophoresis.

Introduction: The optimum follow-up regimen after treatment for early-stage endometrial cancer with curative intent is unknown. The National Comprehensive Cancer Network recommends a physical exam and vaginal cytology every three to six months for two years then at six to 12 month intervals with annual chest X-rays (CXR). However, there is debate as to whether intensive follow-up results in an improvement in outcomes for those with recurrent endometrial cancer.
