Aim: The purpose of our study was to investigate the possible effect of BsmI vitamin D receptor (VDR's) polymorphism on changes in bone mineral density (BMD) and bone turnover markers in postmenopausal women receiving different treatments.
Material And Methods: This pilot study included 42 postmenopausal women with elevated fracture risk, randomized into 1-year treatment with weekly oral alendronate or daily subcutaneous teriparatide. Both groups received daily supplements of 1000 mg calcium and 800 IU vitamin D.
Background: Inherited thrombophilia is associated with both poor obstetrical outcomes and increased cardiovascular risk later in life. In fact, a personal history of spontaneous miscarriage is reported to increase the risk of subsequent ischaemic heart disease.
Aims: This pilot study aims to evaluate the association between genetic polymorphism-related increased risk of arterial thrombosis and the history of spontaneous miscarriage early in pregnancy, among healthy postmenopausal women.
One hundred healthy postmenopausal women were randomly assigned to receive 17β-E2 1 mg/drospirenone 2 mg or 17β-E2 1 mg/norethisterone acetate 0.5 mg for 6 months, and circulating soluble Fas, soluble Fas ligand, and cytochrome c were measured at baseline and at 6 months in 87 women who completed the study. Although cytochrome c levels were undetectable, circulating soluble Fas/soluble Fas ligand ratio decreased in both groups, suggesting a decrease in ligand-mediated apoptosis.

Study Design: We reviewed a number of case reports on benign and malignant müllerian lesions and compared the developments associated with endometriosis, endosalpingiosis and endocervicosis.
Results: Our sampling of case reports confirm the suggestion that both malignant neoplasms and benign müllerian lesions can arise in foci of endometriosis in both pelvic and extrapelvic sites.
Hyperprolactinemia has been associated with endothelial dysfunction and an adverse cardiovascular risk profile, possibly as a result of the vasoconstrictive properties of prolactin. In this cross-sectional study, we examined the hypothesis that prolactin contributes to the increased cardiovascular risk occurring in early menopause by studying apparently healthy women without hyperprolactinemia. Prolactin serum levels were measured by immunoassay in 76 women aged 54.

Classic theories have failed to propose a precise pathogenetic mechanism. Recent studies have investigated the role of the immune system and oxidative stress in the development of endometriosis as well as the identification of biomarkers for a non-invasive diagnosis of the disease.

Objective: To assess the association of genetic polymorphisms related to cardiovascular disease (CVD) risk with anthropometric parameters and indices of androgenicity in healthy postmenopausal women.
Design: Cross-sectional study in a University Menopause Clinic.
Methods: The following polymorphisms were assessed in 84 healthy postmenopausal women: glycoprotein IIIa Leu33Pro, apolipoprotein E2/E3/E4, methylenetetrahydrofolate reductase (MTHFR) Ala222Val, apolipoprotein B Arg3500Gln, paraoxonase 1 Gln192Arg, plasminogen activator inhibitor 1 4G/5G, cholesterol-7 alpha-hydroxylase A-204C, and cholesterol ester transfer protein (TaqIB) B1/B2.
Apoptosis in atherosclerotic lesions is triggered by inflammatory processes, both via cell-cell contact and by cytokines and oxidized lipids. The role of apoptosis in atherogenesis is dual, depending on the stage of the plaque: In early stages, apoptotic death of smooth muscle--and inflammatory cells, such as lymphocytes and macrophages--may delay atherosclerotic process. However, once the plaque is formed, apoptosis may lead to plaque rupture and thrombosis.

Design: The study investigated 84 healthy postmenopausal women recruited from the Menopause Clinic of the 2nd Department of Obstetrics and Gynecology, University of Athens, Aretaieion Hospital. The following polymorphisms were genotyped: apolipoprotein B 3500, apolipoprotein E (E2/E3/E4), cholesterol 7 alpha-hydroxylase A-204C (CYP A-204C), cholesterol ester transfer protein B1/B2, glycoprotein IIIa leu33pro, integrin beta 3 PLA1/PLA2, plasminogen activator inhibitor 1 4G/5G, paraoxonase 1 gln192 arg, and methylenetetrahydrofolate reductase ala222val.
Objective: To evaluate the hypothesis of increased systemic oxidative stress in patients with endometriosis.
Setting: Tertiary care university hospital.
Design: Cross-sectional study.
Background: Leptin and ghrelin are increasingly being recognized as cardiotropic hormones, promoting or inhibiting the atherosclerotic process, respectively. Apoptosis may be one pathway through which the actions of these hormones are mediated. Sex hormones are reported to influence the secretion and action of ghrelin and leptin.

Objective: To analyse the aetiopathogenesis and the role of defective 'immunosurveillance' in endometriosis.
Method: Review of studies on the pathogenesis of endometriosis, focusing particularly on novel molecules which express adhesive or proteolytic properties. Hypotheses addressing the role of oxidative stress in endometriosis were also reviewed.
This study assesses the possible associations between postmenopausal therapy (hormone therapy, raloxifene, and tibolone) and E-cadherin expression in normal cervical Papanicolaou smears (squamous, glandular, and metaplastic cells). E-cadherin immunostaining was less intense in metaplastic cells of women on tibolone, whereas hormone therapy and raloxifene were not associated with altered E-cadherin expression.

Thoracic endometriosis syndrome (TES) is a rare disorder characterized by the presence of functioning endometrial tissue in the pleura, the lung parenchyma and the airways. TES may present with hemoptysis, due to the shedding of endometrial tissue in the bronchial tree, or spontaneous pneumothorax or hemothorax if the endometrial tissue is localized peripherally.

Methods: A retrospective analysis of 667 cases of moderate and severe endometriosis laparoscopically and histologically confirmed during the period 1997-2004.
Results: One hundred and ninety-three (29%) of cases were American Fertility Society (AFS) stage III (moderate endometriosis) and 473 (71%) were AFS stage IV (severe endometriosis).
Bisphosphonates belong to a class of compounds similar to pyrophosphate. In these compounds the oxygen atom of the pyrophosphate is replaced by a carbon atom resulting in a P-C-P bond. They exert a potent inhibitory effect on osteoclasts and are therefore potent antiresorptive agents.

Methods: Thirty healthy women were enrolled in the study for climacteric symptoms and received a combination of 17beta-estradiol and norethisterone acetate continuously for 2 years. An untreated group, consisting of 25 healthy postmenopausal women presenting the same symptoms and not willing to receive HRT, were also studied and served as controls.
Aim: To evaluate the association of serum corticotropin-releasing hormone (CRH) and tumor necrosis factor-alpha (TNF-alpha) in preterm labor.
Methods: Forty-nine primigravidas with a singleton viable pregnancy between 28 and 34 weeks of gestation were studied. They were divided into two groups.
Background: The cardinal role of chronic inflammation in the development of atherosclerosis is increasingly being recognized. Estrogens may prevent the evolution of atherosclerosis by suppressing immune response. Furthermore, the conflicting reports on the cardiovascular effects of hormone therapy between observational and clinical trials have triggered interest on the effect of alternative therapies on the cardiovascular system.
