OBJECTIVES: Venous thromboembolism (VTE) risk increases within months of combination oral contraceptive (COC) initiation. Because elevated endogenous thrombin potential (ETP) has been found in several studies to be a VTE risk factor, we evaluated the extent of ETP changes during the initial cycle of an ethinyl estradiol (EE) and levonorgestrel (LNG) COC. We also assessed the relationship between ETP changes and systemic EE and LNG concentrations. STUDY DESIGN: Participants provided multiple blood samples during a first 21-day cycle of a 30 μg EE/150 μg LNG COC and after a further 7 days without an active COC...

Understanding the contraceptive practices of women with complex congenital heart disease (CHD) and providing them individualized contraception counseling may prevent adverse events and unplanned high-risk pregnancies. Given this, we sought to examine the contraceptive practices in women with CHD, describe adverse events associated with contraceptive use, and describe the provision of contraception counseling. Women >18 years were recruited from 2011 to 2014 from 9 adult CHD (ACHD) centers throughout North America...

OBJECTIVES: Hormonal changes during oral contraceptive pill (OCP) use may affect central corneal thickness (CCT) values. We aimed to evaluate the impact of OCP use on CCT values in healthy young women. MATERIALS AND METHODS: Fifty women subjects who use OCP for contraception (Group 1) and forty control subjects (Group 2) who do not use OCP were included in this prospective study. None of the patients had any history of systemic or ocular diseases. The CCT values measured by ultrasonic pachymeter (Nidek US-4000 Echoscan, Japan) and the intraocular pressure (IOP) values were measured by noncontact tonometer (Reichert 7 CR Corneal Response Technology, USA) at the time of admission to our clinic...

OBJECTIVES: Despite the progress in the diagnosis and treatment of breast cancer, it remains a major health problem in women. Natural flavones along with chemotherapeutic agents enhance therapeutic response and minimize toxicity of chemical agents. Centchroman (CC) colloquially called as ormeloxifene, is a nonsteroidal oral contraceptive categorized as selective estrogen receptor modulator with anti-breast cancer activity. Genistein (GN), an isoflavone found mainly in soy products possesses anti-cancerous potential against a number of cancers including breast...

Drospirenone has been used as a progestin in oral contraceptives with ethinyl estradiol (DRSP/EE) and is expected to regulate endometriosis, however, the direct effects of drospirenone on endometriosis have not been clarified. The aim of this study was to evaluate the anti-inflammatory, anti-angiogenic and anti-neurogenic effects of drospirenone on endometriotic stromal cells (ESC). ESC isolated from endometriotic tissues were obtained from patients during laparoscopic surgery for ovarian endometriosis. ESC were exposed to IL-1β and cultured in the absence or presence of drospirenone...

Focal nodular hyperplasia (FNH) of the liver is a benign lesion occurring in 0.6%-3% of the general population that probably reflects a local hyperplastic response of hepatocytes to a vascular abnormality. Most lesions are diagnosed incidentally and the natural history of the disease remains largely unknown. It has been shown that most FNH remain stable, or even regress, over a long follow-up period. We present a patient with FNH of the liver who was followed up for 7 years. A 26-year-old woman with a 5-year history of oral contraceptive use was referred to our hospital in February 2005 for further examination of a liver tumour...

BACKGROUND: Lack of information has been described as a major factor in non-use of oral emergency contraception (EC) following unprotected intercourse. Despite the ongoing vociferous debate on liberalisation of access, little evidence is available on EC knowledge in Germany, particularly among adolescents. METHODS: We conducted a cross-sectional survey among ninth graders in convenience sample of 13 Berlin schools. We assessed perceived and actual knowledge on the effectiveness, timeframe and availability of EC and on pregnancy risk in six scenarios...

PURPOSE: Cancer antigen 125 (CA125) is a glycoprotein expressed by epithelial cells of several normal tissue types and overexpressed by several epithelial cancers. Serum CA125 levels are mostly used as an aid in the diagnosis of ovarian cancer patients, to monitor response to treatment and detect cancer recurrence. Besides tumor characteristics, CA125 levels are also influenced by several epidemiologic factors, such as age, parity, and oral contraceptive use. Identifying factors that influence CA125 levels in ovarian cancer patients could aid in the interpretation of CA125 values for individuals...

INTRODUCTION: Oral contraceptives are one of the risk factors for gingival disease. Oral contraceptives can affect the proliferation of cell, growth and differentiation of tissues in the periodontium. Nowadays recent research has suggested that the newer generation oral contraceptives have less influence on gingival diseases. AIM: The purpose of this study was to systematically review the effect of oral contraceptives on periodontium. MATERIALS AND METHODS: A literature review was performed; PubMed, PubMed Central and Cochrane Library, Embase, Google Scholar were searched from 1970 up to December 2015 to identify appropriate studies...

OBJECTIVE: The gold standard for measuring oral contraceptive (OC) pharmacokinetics is the 24-h steady-state area-under-the-curve (AUC). We conducted this study to assess whether limited sampling at steady state or measurements following use of one or two OCs could provide an adequate proxy in epidemiological studies for the progestin 24-h steady-state AUC of a particular OC. STUDY DESIGN: We conducted a 13-sample, 24-h pharmacokinetic study on both day 1 and day 21 of the first cycle of a monophasic OC containing 30 μg ethinyl estradiol and 150 μg levonorgestrel (LNG) in 17 normal-weight healthy white women, and a single-dose 9-sample study of the same OC after a one-month washout...

OBJECTIVE: The peak number of oocytes is reached during intrauterine development, after which numbers decline until reserves are depleted and a woman enters menopause. In premature ovarian insufficiency (POI), the process of follicle depletion occurs at a young age (generally taken as 40 years); the condition affects about 1% of women. In this study, we investigate whether women with POI had experienced a different perinatal milieu, as reflected in their birth weight or prematurity. STUDY DESIGN: In this retrospective case-control study, we evaluated whether women diagnosed with POI had a different birth weight or prematurity rate (<37 weeks) compared with women aged over 40 at natural menopause (the controls)...

AIM: Recent investigations have demonstrated that athletes with high relaxin-2 levels have a high risk of anterior cruciate ligament injuries, while athletes taking oral contraceptives (OC) have low relaxin-2 levels. It has not yet been clarified whether taking OC reduces relaxin-2 levels. The purpose of this study was to investigate changes in relaxin-2 levels in athletes taking OC. METHODS: Levels of relaxin-2, estradiol, progesterone, luteinizing hormone and follicle-stimulating hormone were measured in serum samples (n = 183) from 106 elite female athletes...
