Leila Top, Nicolaos Salakos, Michalis Kaloeidas, Georgios Koumantakis, Perilkis Panagopoulos, Efthimios Deligeoroglou

Aim: The aim of this study is to summarize the methods used for contraception from antiquity to nowadays and to highlight the latest ones with their advantages and disadvantages.
Materials and Methods: In order to gather the following data, scientific papers from the PUBMED database, ancient texts, historical data, newer article-searching literature, contraceptive methods and the collection of books of the Family Planning Department of the 2nd Department of Obstetrics & Gynecology of the Aretaieion Hospital.
Results: Contraception is a means of controlling fertility, is an old and sexual function. The history of contraception began with the discovery of the relationship between intercourse and pregnancy. Over the years many contraceptive methods have emerged, involving mechanical components up to the use of pharmaceuticals, and several of them were natural and others were artificial.
Conclusions: Today contraception provides the couples with the opportunity to determine both the time and number of pregnancies. The progress in the decrease of the number of unwanted pregnancies and the provision of contraception with minimal side effects is a collective effort requiring constant collaboration of reliable clinics, scientists and volunteers of clinical trials in combination with the collaboration of the pharmaceutical industry, family planning organizations and the government. The new contraception alternatives are going to improve the opportunities of an appropriate, acceptable contraceptive method by the wider public, eliminating thus birth control failure.

Key Words: Contraception, methods of contraception, history of contraception, new methods of contraception.

Assisted Reproduction in Congenital Adrenal Hyperplasia

Anastasios Chatziaggelou, Evangelos G. Sakkas , Raffaella Votino, Maria Papagianni , George Mastorakos

Congenital Adrenal Hyperplasia (CAH) is a group of autosomal recessive disorders characterized by defects of adrenal steroidogenesis due to mutations in one of the following enzymes: 21-hydroxylase (21OH), 11b-hydroxylase (11bOH), 17a-hydroxylase (17OH; also known as 17, 20-lyase), 3b hydroxysteroid dehydrogenase type 2 (3bHSD2), steroidogenic acute regulatory protein (StAR), P450 cholesterol side-chain cleavage (P450scc), and P450 oxidoreductase (POR). More than 95% of congenital adrenal hyperplasia cases are due to mutations in CYP21A2, the gene encoding the adrenal steroid 21-hydroxylase enzyme (P450c21). This work focuses on this type of CAH given that it is the most frequent one. This disease is characterized by impaired cortisol and aldosterone production as well as androgen excess. A variant of the CAH is the non-classic type of CAH (NCCAH), usually asymptomatic before the 5th year of age, diagnosed during puberty especially in patients visiting a fertility clinic. NCCAH is characterized mainly by anovulatory cycles and/or high androgen concentrations. Both types of CAH are associated with infertility. Given that the incidence of NCCAH is greater than that of CAH, patients suffering from NCCAH are more often diagnosed for the first time in a fertility clinic. Thus, screening for NCCAH should always be considered. The causes of infertility in CAH patients are multi-factorial including virilization of external genitalia, altered psychosocial development, and hormonal disorders. The main challenges encountered in assisted reproduction are the androgen excess-associated anovulatory cycles as well as the increased circulating progesterone concentrations during the follicular phase which impact endometrial receptivity, tubal motility, and cervical thickness. Administration of sufficient substitution dose of glucocorticoids usually resolves these problems and leads not only to successful assisted reproduction treatment but also to spontaneous pregnancy. Patients with CAH should be followed by a multidisciplinary team including gynecologist, endocrinologist, and pediatrician.

Keywords: infertility, IVF (in vitro fertilization), congenital adrenal hyperplasia (CAH), pregnancy, assisted reproduction (ART)

Demographic, clinical and hormonal characteristics of patients with premature ovarian insufficiency and those of early menopause: data from two tertiary premature ovarian insufficiency centers in Greece

 

The aim of the study was to compare demographic, hormonal and clinical parameters in patients with premature ovarian insufficiency (POI) and women with early menopause in Greece. One hundred thirty-nine women of Greek origin, aged 14–45 years, referring for oligomenorrhea and having elevated FSH concentrations were divided into three groups regarding the age of menstrual disturbances onset [POI1: </=30 years (n = 42); POI2: 31–39 years (n = 36); early menopause: 40–45 years (n = 61)].

The mean age of menstrual disturbances onset and that of diagnosis in all POI and early menopause patients were 28.7 years (28.7 ± 7.7) versus 42.1 years (42.1 ± 1.5) and 33.8 years (33.8 ± 7.2) versus 43.3 years (43.3 ± 1.4), respectively. POI patients and women with early menopause were diagnosed, respectively, five years and approximately four to six months later than the age of menstrual disturbances onset. Moreover, FSH2 (second confirmatory FSH measurement at 4-to-6-weeks interval) was greater in all POI patients than in early menopause women (55.4 ± 33.9 vs. 32.4 ± 19.4; p < .05) whereas mean age of menarche was greater in early menopause women than in POI patients (13 ± 1.3 vs. 12 ± 2.2; p < .05). Furthermore, FSH2 was increased in all POI and decreased in early menopause patients.

The effects of autoimmune disorders on mental health of women in reproductive age.

Hell Iatr 2018; 84: 15-22.

Salioni A-M, Christopoulos P, Zervas I, Mastorakos G.

Nowadays, we know how important is to understand being healthy. Contrary to this, we have to investigate more and more the hidden faces of longterm illnesses and find the reasons of morbidity. The activation of autoimmunity inclines to be increased in contemporary time, not only in Greece, but also globally, without understanding the causes. The systematic erythematosus lupus (SEL) and rheumatoid arthritis (RA) are, probably, two of the most characteristic examples of up to date chronic autoimmunity diseases. Women are more frequent affected than men in proportion of 3:1, a fact that create changes not only physical and organic, but also psychological. Additionally, there are a lot of chances either in childhood or in reproductive and old one. The psychological morbidity is taking place in most of these diseases, affecting the patients’ behavior and their position against them. Multiple factors are incriminated for their appearance, as fatigue, stress, anxiety, etc. In addition a lot of causes affect their development both at their remission and at their relapse. The depression dominate and is promptly correlated both with the systematic erythematosus lupus and rheumatoid arthritis.
