Prolidase is a manganese (Mn)-dependent cytosolic exopeptidase that degrades imidodipeptides with C-terminal proline or hydroxyproline. Prolidase recycling from imidodipeptides plays a critical role in collagen resynthesis and extracellular matrix (ECM) remodelling. Following an increase in gonadotropins, ovarian and follicular collagen undergo substantial degradation.

Transmediastinal gunshot wounds (TGWs) may lead to life-threatening injuries of vital organs such as large vessels, the esophagus, and lungs. Although they are not commonly encountered in pregnant women, additional caution should be given to these patients. Physical examination for the diagnosis and the choice of treatment modality contain controversial points in hemodynamically stable patients, and resuscitation has excessive importance due to physiological changes in pregnancy.

Objective:  Primary dysmenorrhea occurs due to abnormal levels of prostanoids, uterine contractions, and uterine blood flow. However, the reasons for pain in primary dysmenorrhea have not yet been clarified. We examined the blood flow alterations in patients with primary dysmenorrhea and determined the relationship between ischemia-modified albumin (IMA) levels, as an ischemia indicator, and primary dysmenorrhea.

Lymphangiomas are rare benign tumors which are generally seen in pediatric population and the etiopathogenesis has not yet been understood. They occasionally occur in the head and neck or axillary region with only 5% of them being located in the abdominal or mediastinal cavity. These tumors may be asymptomatic or may cause acute abdominal symptoms due to the location and extention.

Sclerosing stromal tumours are rare benign ovarian neoplasms of the sex cord stromal that occur predominantly in the second and third decades of life. To date, fewer than 200 cases have been described in the literature and most patients have menstrual irregularities and pelvic pain. Sclerosing stromal tumours were reported in which the inactive tumours did not represent endocrine clinical symptoms; however, currently according to several reports, it is the active tumour that produce hormones.

Background: Ovarian hyperstimulation syndrome (OHSS) is the most serious and potentially life-threatening iatrogenic complication associated with ovarian stimulation during assisted reproductive technology protocols. The aim of this study was to evaluate the role of dopamine agonist as a preventive strategy of OHSS in women at high risk in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment cycles.

Methods: Seventy women at risk to develop OHSS undergoing IVF/ICSI treatment cycle were included.

Mixed epithelial ovarian carcinomas are extremely rare and comprise less than 4% of all malignant ovarian tumors. We report a 61-year-old postmenopausal woman with bilateral adnexal masses. In the postoperative histopathological evaluation, mixed epithelial carcinoma with areas of disseminated serous adenocarcinoma and less prevalent areas of malignant transitional cell carcinoma was observed.

Background: Endocan, a cysteine-rich dermatan sulfate proteoglycan expressed by endothelial cells, is seemed to be a new biomarker for endothelial dysfunction. Pre-eclampsia (PE) is characterized by the new onset of hypertension, proteinuria after 20 weeks of gestation, placental vascular remodeling, systemic vascular inflammation and endothelial dysfunction. The aim of this study was to investigate the relationship of PE and its severity with serum endocan levels.
