The aim of this study was to evaluate the immunological activities of human decidual mesenchymal stem cells (MSCs) on proliferation, apoptosis and percentage of regulatory T cells (Treg) in abortions and to investigate whether these activities differ in spontaneous abortions (SA) and recurrent abortions (RA). This prospective cohort study included women who had a first-trimester abortion between 2019 and 2022. Women with uterine anomaly, endocrinological disease, known autoimmune or thrombophilic disease, and fetal chromosomal abnormality in abortion material were excluded.

New molecular therapies are available for the treatment of spinal muscular atrophy (SMA) but early intervention is required. We report two cases that were diagnosed prenatally, where treatment with nusinersen was initiated within 7 h and three days respectively. The children were followed up for 13 months and almost six years respectively.

Prompt and accurate diagnosis of polymicrobial bacteremia, which causes the difficulty in anti-infective treatments, poor treatment outcome and high mortality, is essential for initiating effective antimicrobial therapy. Here we present a case of bacteremia caused by two types of uncommon bacteria, Lactobacillus jenseniand and Veillonella montpellierensis in a 29-year-old pregnant woman at 33 weeks of gestation with anemia due to iron deficiency. She had no comorbidity or other chronic illnesses and was successfully treated with appropriate antibiotic use.

Background: Considering the changes in thyroid physiology associated with pregnancy and poor outcomes related to abnormal maternal thyroid function, international guidelines recommend using population-based trimester-specific reference intervals (RIs) for thyroid testing. If these RIs are not available in the laboratory, implementing recommended fixed cut-off values globally is still controversial. To address this issue, we aimed to establish appropriate RI of thyroid-stimulating hormone (TSH) in pregnant Turkish women for our laboratory and compare the prevalence of thyroid dysfunction based on the established and recommended criteria.

Aim: To compare the classical double-layer uterine closure to a double-layer purse-string uterine closure (Turan technique) in cesarean section regarding short- and long-term results.

Methods: Patients were randomized into either the double-layer purse-string uterine closure arm (study group, 84 patients) or the classical double-layer uterine closure arm (control group, 84 patients). For short-term comparison, a detailed transvaginal ultrasound examination was planned in all patients 6 weeks after the operation and a wedge-shaped defect in the uterine incision scar was accepted as uterine scar defect and recorded.

Article Synopsis
  • - The study aimed to evaluate the effectiveness of tetracycline sclerotherapy combined with cyst aspiration versus aspiration alone for treating recurring non-neoplastic ovarian cysts in 96 patients.
  • - Patients were divided into two groups: one received both aspiration and tetracycline sclerotherapy, while the other only received aspiration. Follow-ups were done monthly for a year using ultrasound.
  • - Results showed significantly lower recurrence rates for the group that received tetracycline sclerotherapy (14.6%) compared to the aspiration-only group (50%), suggesting that the combination method is more effective.

Essential thrombocythaemia (ET) is a disease characterized by an increased platelet count, megakaryocytic hyperplasia and a hemorrhagic or thrombotic tendency. Pregnancy in patients with ET can have a favorable outcome. However, ET has also been reported to complicate pregnancy by recurrent abortions, intrauterine death, and fetal growth retardation due to placental infarctions.

Purpose: To determine the diagnostic accuracy of different diagnostic methods (blind dilatation & curettage (D&C), transvaginal ultrasonography (TVS), sonohysterography (SH), and hysteroscopy) compared with gold standard (hysteroscopic biopsy's histopathologic result) in diagnosis of focal intrauterine lesions of recurrent postmenopausal bleeding.

Methods: 36 postmenopausal women with recurrent vaginal bleeding after a normal D&C results were enrolled into the study. TVS, SH, hysteroscopy were performed on all patients.

Article Synopsis
  • The study compares the effectiveness of vaginal versus sublingual misoprostol for terminating second-trimester pregnancies and its impact on blood flow in uterine and umbilical arteries.
  • Forty-nine patients were randomly assigned to receive misoprostol either vaginally or sublingually, with various assessments done before and after treatment.
  • Results indicated that sublingual misoprostol led to shorter times for active labor and delivery, and while both methods increased uterine artery blood flow, only the sublingual method did not affect the umbilical arteries.

Pregnancy and cancer is a complex situation. The coincidence of chronic myelogeneous leukemia (CML) and pregnancy is an uncommon event, in part because CML occurs mostly in older age groups. The management of CML during pregnancy is a difficult problem because of the potential effects of the therapy on the mother and fetus.

Imperforate hymen is a urogenital tract anomaly that represents the most frequent congenital malformation of the female genital tract. CA 19-9 and CA 125 are widely used as tumor markers, however several benign conditions are also known to increase serum CA 19-9 and CA 125 levels. According to classical textbook knowledge, imperforate hymen is not listed under the benign conditions that increase serum CA 19-9 and CA 125 levels.
