Risk of gestational hypertension in pregnancies complicated with ovarian hyperstimulation syndrome.

Objective: Ovarian hyperstimulation syndrome (OHSS) is the most common iatrogenic complication due to ovulation stimulation during assisted reproductive technology. Pathophysiology of this syndrome is not completely clarified, and there is no some specific treatment. Human chorionic gonadotropin is considered as the most significant factor in etiopathogenesis of OHSS.

Risk of spontaneous preterm labor in pregnancies achieved by in vitro fertilization and complicated with severe form of ovarian hyperstimulation syndrome: A case control study.

Objectives: The purpose of this study was to examine the potential impact of severe Ovarian hyper stimulation syndrome (OHSS) on the risk of preterm birth. Severe ovarian hyperstimulation syndrome is a serious complication in the methods of in vitro fertilization. The pathophysiology of this process is not clear enough and the treatment is symptomatic.

Massive fetomaternal hemorrhage as a cause of severe fetal anemia.

Introduction: Fetomaternal hemorrhage (FMH) is a transfu-sion of fetal blood into the maternal circulation. A volume of transfused fetal blood required to cause severe, life-threatening fetal anemia, is not clearly defined. Some authors suggest vol-umes of 80 mL and 150 mL as a threshold which defines mas-sive FMH.

Diagnostic value of breast ultrasound in mammography BI-RADS 0 and clinically indeterminate or suspicious of malignancy breast lesions.

Background/aim: Not only that ultrasound makes the difference between cystic and solid changes in breast tissue, as it was the case at the beginning of its use, but it also makes the differential diagnosis in terms of benign-malignant. The aim of this study was to assess the role of sonography in the diagnosis of palpable breast masses according to the American College of Radiology Ultrasonographic Breast Imaging Reporting and Data System (BI-RADS) and to correlate the BI-RADS 4 and BI-RADS 5 category with pathohistological findings.

Methods: A retrospective study was conducted with the breast sonograms of 30 women presented with palpable breast masses found to be mammography category BI-RADS 0 and ultrasonographic BI-RADS categories 4 and 5.

Melatonin: a "Higgs boson" in human reproduction.

As the Higgs boson could be a key to unlocking mysteries regarding our Universe, melatonin, a somewhat mysterious substance secreted by the pineal gland primarily at night, might be a crucial factor in regulating numerous processes in human reproduction. Melatonin is a powerful antioxidant which has an essential role in controlling several physiological reactions, as well as biological rhythms throughout human reproductive life. Melatonin, which is referred to as a hormone, but also as an autocoid, a chronobiotic, a hypnotic, an immunomodulator and a biological modifier, plays a crucial part in establishing homeostatic, neurohumoral balance and circadian rhythm in the body through synergic actions with other hormones and neuropeptides.

Three-dimensional transvaginal ultrasonographic view of intact cornual pregnancy.

This work presents the case of the cornual ectopic pregnancy of a twenty year old patient who came to be examined due to amenorrhea which had lasted for seven weeks. Two-dimensional transvaginal ultrasound uncovered the existence of an intact ectopic pregnancy. Use of three-dimensional transvaginal ultrasound in a coronal section confirmed the diagnosis of cornual ectopic pregnancy, and the patient underwent laparatomy.
